Abstract: A user equipment (UE) is configured with multi-transmission and reception point (multi-TRP) operation. The UE groups capabilities of handling two overlapping physical downlink shared channel (PDSCH) transmissions into a plurality of groups, determining a UE capability of handling two overlapping PDSCH transmissions based on the plurality of groups and transmits the UE capability to a next generation nodeB (gNB) of a 5G new radio (NR) wireless network. The UE also determines if a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH) transmission collides with a cell-specific reference signal (CRS) of a long term evolution (LTE) transmission and determines if the CRS originated from a same multi-transmission/reception point (TRP) as the DMRS.

Abstract: Embodiments of the present disclosure relate to aperiodic sounding reference signal (SRS) transmission. According to embodiments of the present disclosure, the collision of the triggered SRS resource sets (such as, the SRS resource set being triggered too early or the triggered SRS resource sets being overlapped in time and/or frequency domain) may be well handled, and the configuring and updating procedures for SRS resource may be more flexible.

Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

Abstract: Embodiments of the present disclosure relate to downlink data reception operation. According to embodiments of the present disclosure, a baseband processor of a user equipment (UE) is configured to perform operations comprising receiving Downlink Control Information (DCI) through more than one beams from at least one from at least one TRP; determining a DCI transmission scheme for the received DCI, wherein the DCI transmission scheme is configured by an upper layer signaling, and wherein the DCI transmission scheme is one of a Single Frequency Network (SFN) scheme, a non-SFN scheme, and a hybrid scheme, wherein the DCI is transmitted using both SFN scheme and non-SFH scheme in the hybrid scheme; determining whether the received DCI indicates a Transmission Configuration Indicator (TCI) for PDSCH reception from the at least one TRP or not. The operations further comprise in accordance with a determination that the received DCI fails to indicate the TCI and based on the determined DCI transmission scheme, selecting at least one TCI for the PDSCH reception from candidate TCIs configured for one or more Control Resource Sets (CORESETs) associated with the DCI.

Abstract: Some aspects include an apparatus, method, and computer program product for identifying a panel on user equipment (UE) for sounding reference signal (SRS) and/or physical uplink shared channel (PUSCH) communications. This panel selection may be applicable to codebook as well as non-codebook based PUSCH transmission schemes. In some aspects, a base station may provide the UE with an indication of one or more SRS resources and/or sets of SRS resources. The UE may then identify a panel corresponding to the indicated SRS resources and use this panel for PUSCH communications. In some aspects, the UE may apply prioritization scheduling when the UE uses different panels for SRS and PUSCH communications. This prioritization scheduling may address switching delays, which may occur when the UE switches between panels.
