SingleRAN CDMA and LTE Zero Bufferzone Feature Parameter Description
2 Overview

Overview
2.1 Background As networks evolve from CDMA to LTE, inter-RAT intra-frequency interference may occur at the coverage edges of these two networks. To reduce the interference, the conventional solution is to geographically isolate LTE coverage areas from CDMA coverage areas by planning a buffer zone in between. However, LTE cells working on the same frequency as nearby CDMA cells cannot be deployed in the buffer zone, which leads to a significant waste of spectrum resources. The CDMA and LTE Zero Bufferzone feature has been introduced to reduce this waste of spectrum resources. This feature uses the spectrum resources in the buffer zone to deploy LTE cells, improving spectral efficiency and eliminating the need to plan the buffer zone.
2.2 Introduction The CDMA and LTE Zero Bufferzone feature optimizes uplink and downlink scheduling for LTE, reducing the inter-RAT intra-frequency interference between CDMA and LTE networks. This feature involves the refarming of existing CDMA spectrum. Two concepts will be particularly important to understand how the feature works: dedicated spectrum and shared spectrum. The relationship between dedicated and shared spectrums is illustrated in Figure 2-1 below, using an LTE cell with a bandwidth of 5 MHz as an example. Figure 2-1 Dedicated and shared spectrums

2 Overview
NOTE
CDMA 1x is short for CDMA 1 times radio transmission technology and EV-DO for Evolution-Data Optimized.
2.3 Benefits Increasing LTE Network Capacity This feature uses the shared spectrum in the buffer zone to deploy LTE cells, which increases spectral efficiency and improves the network capacity and user experience for LTE. Take a 10 MHz spectrum for example. The spectrum consists of the CDMA-dedicated spectrum (5 MHz), the CDMA/LTE shared spectrum (one or two CDMA carriers), and the LTE-dedicated spectrum. If this feature is not used, only a 1.4 or 3 MHz spectrum can be used to deploy LTE cells in the buffer zone. But with this feature, there will be a 5 MHz spectrum available to deploy LTE cells there. The uplink and downlink capacities will be, respectively, 200% and 110% greater than when there was only 1.4 MHz available. If there had originally been 3 MHz available for LTE deployment, the respective uplink and downlink capacity gains will be 45% and 25%. Figure 2-2 Feature application in the 10 MHz spectrum scenario
NOTE
The capacity gains mentioned above are obtained under the assumption that all remaining resource block (RB) resources can be scheduled. On live networks, the capacity gains may decrease by up to 20%.

Technical Description
3.1 Overview The eNodeB determines whether an LTE UE is a cell edge user (CEU) or a cell center user (CCU) based on the reference signal received power (RSRP) measured by the UE and the feature configuration. The eNodeB then optimizes uplink and downlink scheduling for the UE, which reduces the inter-RAT intra-frequency interference between CDMA and LTE networks. l
If the eNodeB determines that a UE is CEU, the UE can occupy the RBs only on the LTE-dedicated spectrum during physical uplink shared channel (PUSCH) or physical downlink shared channel (PDSCH) scheduling.
l
If the eNodeB determines that a UE is CCU, the UE can occupy the RBs on both the LTE-dedicated spectrum and shared spectrum during PUSCH or PDSCH scheduling.
The CDMA and LTE Zero Bufferzone feature is controlled by the AvoidCDMAInterfSwitch option of the AvoidInterfSwitch parameter. This feature supports no more than two shared spectrums. The start RB position and end RB position of the first shared spectrum are specified by the ClSharedFreqStartRb1 and ClSharedFreqEndRb1 parameters respectively. The start RB position and end RB position of the second shared spectrum are specified by the ClSharedFreqStartRb2 and ClSharedFreqEndRb2 parameters respectively.
3.2 Reducing PUSCH Interference The eNodeB uses different PUSCH RB scheduling solutions for UEs based on the configuration policy of the shared spectrum, the uplink physical resource block (PRB) usage, and the UE location to reduce mutual interference between an LTE PUSCH and a CDMA carrier. Figure 3-1 shows the PUSCH RB scheduling process.

If the RSRP of a UE is greater than the value of the UlNearPtUserRsrpThd parameter, the eNodeB considers the UE a CCU.
3.3 Reducing PDSCH Interference The eNodeB uses different PDSCH RB scheduling solutions for UEs based on the configuration policy of the shared spectrum and the UE location to reduce mutual interference between an LTE PDSCH and a CDMA carrier. Figure 3-2 shows the PDSCH RB scheduling process. Issue 03 (2016-06-23)

When cells enabled with the CDMA and LTE Zero Bufferzone feature and other common cells are involved in UL CoMP, the benefits provided by UL CoMP may be affected if the uplink spectrums available for these cells are inconsistent. Only the LTE-dedicated spectrum can be scheduled at the edge of cells enabled with CDMA and LTE Zero Bufferzone. If the proportion of the LTE-dedicated spectrum to all spectrums is 75% and these cells and other common cells are involved in UL CoMP, only the LTE-dedicated spectrum can obtain combination gains, which are lower than those obtained in normal situations.

LTE-A Introduction
When the CDMA and LTE Zero Bufferzone feature is enabled on the secondary cell (SCell) in CA scenarios: l LTE-A Introduction has the following impacts on this feature if the secondary carrier is configured with downlink SCell but not with uplink SCell: CA UEs cannot estimate path loss through uplink RSRP measurement. As a result, the eNodeB cannot determine whether a CA UE is a CCU. Even though a CA UE is a CCU, uplink and downlink shared spectrums cannot be scheduled. l LTE-A Introduction has no impact on this feature for non-CA UEs, or if the secondary carrier is configured with both uplink SCell and downlink SCell.

l
Impact on CDMA system capacity Both uplink and downlink capacities may decrease by 5% to 15%.
Network Performance If there is no inter-RAT intra-frequency interference between CDMA and LTE networks before feature activation, activating this feature may generate the interference. The data rates of LTE UEs at the coverage edge may decrease because the PDCCH experiences more interference and the coverage area of the LTE cell shrinks. To avoid this problem, configure CDMA pilot beacons (PBs) to isolate the interference or hand over the LTE UEs at the coverage edge to LTE high-frequency cells quickly. This feature will expand the bandwidth available to LTE cells operating in the buffer zone, from 1.4 or 3 MHz, to 5 MHz. The following KPIs will improve for these cells: l
Cell Downlink Average Throughput

Engineering Guidelines
6.1 When to Use CDMA and LTE Zero Bufferzone This feature is recommended if all the following conditions are met: l
CDMA-to-LTE refarming is required.
l
At least 5 MHz of contiguous spectrum is available in the buffer zone.
l
The proportion of the LTE-dedicated spectrum to all spectrums is greater than or equal to 50%. For example, there are four CDMA carriers. If two of them work in the shared spectrum and the other two work in the LTE-dedicated spectrum after CDMA-to-LTE refarming, then the proportion of the LTE-dedicated spectrum to all spectrums is 50%.
l
The inter-site distance is greater than 1 km. If the inter-site distance is less than or equal to 1 km, network performance may deteriorate due to the mutual interference between CDMA and LTE. This is because there is a small difference in the loss between the path from the UE to the serving cell and that from the UE to the neighboring cell.

6.3 Planning 6.3.1 RF Planning Before feature activation, plan the buffer zone based on the engineering parameters and the operator's CDMA and LTE spectrum usage rules. Buffer zone planning is the same as normal CDMA-to-LTE refarming planning. For details, contact Huawei technical support. The following are the recommendations for RF planning: l
It is recommended that spectrum distribution be performed for CDMA-to-LTE refarming in the following order: LTE-dedicated spectrum, shared spectrum, and CDMA-dedicated spectrum.
l
It is recommended that the proportion of the LTE-dedicated spectrum be greater than or equal to 50%. This is to prevent LTE uplink resource insufficiency due to a large difference between the shared spectrum and the LTE-dedicated spectrum.
l
For a CDMA cell where there is a PB at the coverage edge, it is recommended that you keep the PB. For a CDMA cell where there is no PB, it is recommended that you configure a PB at the coverage edge to improve the KPIs.
l
This feature is recommended if the spectrum in which the CDMA intra-frequency carrier operates is at the edge of the LTE spectrum, as shown in Figure 6-1, Figure 6-2, and Figure 6-3.

CDMA carrier that operates in a different frequency from LTE 800 MHz under the guidance of a CDMA PB. When an LTE UE moves from an LTE 800 MHz cell to an LTE 1800 MHz cell during the handover between LTE carriers at the coverage edge, it will be handed over to an interference-free LTE 1800 MHz carrier through an inter-frequency handover.
6.3.2 Network Planning N/A
6.3.3 Hardware Planning 5 MHz LTE is used as an example. The bandwidth of one CDMA carrier is 1.23 MHz, and the bandwidth of four CDMA carriers is only 4.92 MHz. Therefore, the non-standard bandwidth scenario is involved. In dual-mode scenarios, radio frequency (RF) modules must support the Compact Bandwidth feature. At present, only the CRFUe and RRU3653 support the Compact Bandwidth feature in CDMA/LTE dual-mode scenarios. In LTE-only scenarios, 5 MHz LTE can be configured directly. There is no special requirement for RF modules.
