BACKGROUND

Various procedures may be used for selecting wireless communication resources. A wireless device and/or a base station may select one or more beams among the multiple beams for transmission and/or reception of signals. Signaling protocols may not be able to indicate/provide information for the wireless device to select beams, which may result in the wireless device being unable to determine a beam to be used for transmission and/or reception of signals.

SUMMARY

The following summary presents a simplified summary of certain features. The summary is not an extensive overview and is not intended to identify key or critical elements.

Wireless communications using one or more serving beams are described. A wireless device may determine/select one or more beams for transmission of signals (e.g., sounding reference signals, SRSs) to one or more cells. The wireless device may select a beam (e.g., based on various considerations), among a plurality of beams used for transmission of a signal in a first cell, for transmission of another signal in a second cell. The base station may be aligned to use a beam that may be based on a selection rule applied at the wireless device. Beam selection techniques described herein may result in advantages such as improved decoding/reception performance of SRS transmission, uplink channel estimation, uplink scheduling, and/or downlink scheduling.

These and other features and advantages are described in greater detail below.
