摘要： A method of wireless communication includes generating a list of cells for physical broadcast channel (PBCH) decoding. The method also includes allocating memory for decoding and cancelling a subset of cells from the generated cell list. The method further includes storing information related to subsets of cells from the generated list in the allocated memory during different time periods. The allocated memory is sufficient for attempting, at each time period, decoding of each subset of cells and cancelling of decoded cells in each subset. The method further includes cycling through the generated cell list by processing each subset of the cell list during the different time periods.

摘要： Techniques for controlling the transmit power of a user equipment (UE) using multiple antennas for uplink transmission are described. In one design, the UE receives at least one transmit power control (TPC) command for the multiple antennas. The UE adjusts the transmit power for each antenna based on the TPC command(s). In one design, the UE receives a single TPC command for all antennas and adjusts the transmit power for each antenna based on this TPC command. All antennas may then have equal transmit power. In another design, the UE receives multiple TPC commands for multiple antenna groups, one TPC command for each antenna group. Each antenna group may include one antenna or more than one antenna. The UE adjusts the transmit power for each antenna group based on the TPC command for that antenna group. All antennas in each antenna group may have equal transmit power.

摘要： Power adjustment in the user equipment (UE) includes adjusting the transmission power level for each of multiple transport blocks based on the spectral efficiency associated with the transport block. The UE receives a scheduled transport format parameter for each of multiple transport blocks to be transmitted.

The UE will adjust the power according to the determined transmit power level adjustment and transmit each transport block using the adjusted power level.
