Publication number: 20240422774Abstract: Aspects presented herein may enable a base station to perform demodulation reference signal (DMRS)-based channel sounding for a channel between the base station and a UE, such that the base station may configure a more suitable precoding for coherent UL multiple input multiple output (MIMO) transmission(s) of the UE without increasing communication overhead significantly or at all. In one aspect, a base station performs channel sounding for a channel based on a set of physical uplink shared channel (PUSCH) DMRS received from a UE via the channel. The base station selects a precoding to be used by the UE for a subsequent PUSCH transmission via the channel based on the channel sounding. The base station transmits, for the UE via a physical downlink control channel (PDCCH), a transmit precoder matrix indicator (TPMI) indicating the selected precoding, where the PDCCH schedules the subsequent PUSCH transmission for the UE.Type: ApplicationFiled: June 13, 2023Publication date: December 19, 2024Inventors: Jae Ho RYU, Gokul SRIDHARAN, Hari SANKAR, Rebecca Wen-Ling YUAN

Publication number: 20240172295Abstract: Aspects are provided which allow a UE to apply CFO compensation to resolve mismatched RAPIDs caused by uplink Doppler shifts in HST deployments. The UE obtains one or more RARs each including a RAPID, where each of the RARs is responsive to a random access message including a preamble. The UE determines, in each of a threshold number of the one or more RARs, that the RAPID of a corresponding RAR is different than the preamble of a corresponding random access message. The UE then offsets a carrier frequency for each of one or more subsequent random access messages in response to the determination. As a result, mismatched RAPIDs due to uplink Doppler shifts may be avoided and RACH success rates may thereby be improved.Type: ApplicationFiled: May 29, 2021Publication date: May 23, 2024Inventors: Yuyu YAN, Liang HONG, Jie MAO, Levent AYDIN, Erman KOKEN, yongle WU, Rebecca Wen-Ling YUAN, Ziad AHMAD, Brian Clarke BANISTER, Ashok MANTRAVADI, Nanrun WU, Xinyu WANG, Jie ZHU
