Inter-Dependence of BBU Uplink Resource Feature Parameter Trial on 25 Sites in Different Resource Pool HUAWEI TECHNOLOGIES CO., LTD.

 

Inter-Dependence of BBU Uplink Resource Feature Parameter Description Overview: Many operators have have deployed three or four carriers per sector to accommodate increased traffic on UMTS networks. In typical three-sector scenarios, a NodeB supports a maximum of 9 or 12 cells. However, the the uplink resource group that uses only the WBBP boards can serve a maximum of six cells. To serve more cells, more than one uplink resource group is required, but the channel elements (CEs) cannot be shared among the uplink resource groups. To ensure that CEs are shared among the resource groups, Huawei has introduced the WRFD-151210 Inter-Dependence Inter-Dependence of BBU Uplink Resource feature. Activation: Deactivate the cells before changing. //Setting the chain mode for cell deployment on the baseband equipment on the NodeB SET NODEBALGPARA: ULRESWORKMODE=AUTO_CHAIN; //Adding //Add ing all local cells served by uplink baseband equipment 2 to uplink baseband equipment 1 MOD ULOCELL: ULOCELLID=7, LOCELLTYPE=NORMAL_CELL, ULBASEBANDEQMID=1; MOD ULOCELL: ULOCELLID=8, LOCELLTYPE=NORMAL_CELL, ULBASEBANDEQMID=1; MOD ULOCELL: ULOCELLID=9, LOCELLTYPE=NORMAL_CELL, ULBASEBANDEQMID=1; //Adding //Add ing all baseband boards to the same uplink baseband equipment on the NodeB RMV BASEBANDEQM: basebandEqmId=2, basebandEqmType=UL; MOD BASEBANDEQM: BASEBANDEQMID=1, BASEBANDEQMTYPE=UL, OPMODE=ADD, SN=0;//Reestablishing all local cells on the NodeB STR REALLOCLOCELL:; REALLOCLOCELL:;//Activ //Activating ating all logical cells on the RNC Reactivate cell after implementation.
