Abstract
Systems and methods for improved UL performance with SRS antenna switching are provided. A UE may adjust antenna selections and/or antenna switch timing to account for excessive transmission errors due to antenna switching between SRS and PUSCH transmissions. A UE may monitor CRC error rates, and if PUSCH resources next to SRS resources have higher CRC rates above a threshold, the UE may determine if an RSRP difference between the respective antennas is below a threshold. If the RSRP difference is below the threshold, the UE may determine that the antenna port used for SRS may also be used by PUSCH without substantially detrimentally affecting PUSCH. A UE may also determine which SRS resources occurs adjacent to a PUSCH resource most often and assign that SRS resource to a default antenna which may be used for PUSCH transmission. A UE may also adjust antenna switch timing.
