Antenna port mode and transmission mode transitions

摘要

A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.

1. A wireless communication device with one or more antenna ports performing an uplink power control procedure for one or more component carriers that comprises:
a determining unit configured to determine a total transmission power of antenna ports for SRS for each component carrier to generate the determined total transmission power; and an allocating unit configured to allocate the determined total transmission power to be split equally across the configured antenna port for SRS, wherein the number of antenna ports used for SRS transmission for the wireless communication device is configured, wherein the determined total transmission power is defined by a function based on at least the number of PRBs in the component carrier, wherein the number of PRBs is the number of assigned PRBs for SRS for the wireless communication device, wherein the total transmission power of antenna ports for SRS for each component carrier is obtained by reducing a projected transmission power for SRS in a case that a sum of projected values exceeds a maximum transmission power of the wireless communication device, and wherein the sum of projected values is a sum of projected SRS transmission power for component carriers.
