Abstract:

An apparatus of a user equipment (UE) may include a memory and one or more processors operatively coupled to the memory. The processors may process a scheduling trigger to provide channel state information (CSI) and beam information using extra-large physical uplink shared channel (xPUSCH). The processing device may also generate a reporting message comprising CSI and beam information. The processing device may then encode xPUSCH data to include the reporting message.

International Classification:

H04B 7/08
H04B 7/0413
H04B 17/309

Abstract:

Various embodiments herein provide techniques for minimum mean-square error interference rejection combining (MMSE-IRC) processing of a received signal, distributed between a baseband unit (BBU) and a remote radio unit (RRU). The RRU may perform uplink receive beamforming (e.g., using maximum ratio combining (MRC)) based on multiple channel measurements (e.g., a set of multiple sounding reference signal (SRS) channel measurements) obtained on respective measurement signals transmitted by a user equipment (UE). The RRU may send the processed signal to the BBU for further processing. The BBU may perform MMSE-IRC based on the processed signal received from the RRU, e.g., using demodulation reference signals (DM-RSs). Other embodiments may be described and claimed.

International Classification:

H04W 74/08
H04W 16/14
H04L 1/00

Abstract:

Systems, devices, and techniques for wideband operations in unlicensed spectrum are described. A described technique receiving, by a user equipment (UE), a schedule for transmitting on a Physical uplink shared channel (PUSCH) over at least a portion of a plurality of listen-before-talk (LBT) subbands of a bandwidth part (BWP) in an unlicensed spectrum. The scheduled PUSCH bandwidth indicated by the schedule can be greater than a unit bandwidth of a LBT subband. The technique includes performing, by the UE, a LBT procedure on each scheduled LBT subband of the plurality of LBT subbands, each of the scheduled LBT subbands being associated with the scheduled PUSCH bandwidth. The technique includes performing, by the UE, a PUSCH transmission in accordance with the schedule that uses one or more of the scheduled LBT subbands that have passed the LBT procedure.

International Classification:

H04W 72/12
H04W 72/04
H04L 1/18
H04L 5/00

Abstract:

Systems, devices, and techniques for adjusting a user equipment (UE) processing time parameter in a wireless communication system that include transmission and reception points (TRPs) are described. A described technique performed by UE includes receiving a first physical downlink shared channel (PDSCH) from a first TRP corresponding to a first scheduling physical downlink control channel (PDCCH) and a second PDSCH from a second TRP corresponding to a second scheduling PDCCH. The technique further includes transmitting a first hybrid automatic repeat request acknowledgement (HARQ-ACK) message and a second HARQ-ACK message based on the first PDSCH and the second PDSCH in accordance with a first processing time parameter and a second processing time parameter, respectively. The first processing time parameter can be based on a PDSCH mapping type, a processing capability of the UE, and one or more timing characteristics of the first PDSCH and the second PDSCH.

H04B 7/0456

Abstract:

An approach is described that includes receiving a CSI report, where the CSI report includes a channel quality indicator (CQI), a rank indicator (RI), and a precoding matrix indicator (PMI). The approach further includes constructing a precoding matrix based on a linear combination of a plurality of mutually orthogonal digital Fourier transformation (DFT) spatial beams, and determining a number of bits for the PMI of the precoding matrix. The approach also includes determining a space frequency matrix based, at least in part, on the number of bits for the PMI and the precoding matrix, and compressing the space frequency matrix. Finally, the approach includes determining a compressed PMI based, at least in part, on the space frequency matrix.
