Abstract: A user equipment (UE) receives a configuration from a base station for receiving multiple repetitions of a transmission in a slot aggregation. The UE receives an indication indicating one or more beams used for the multiple repetitions of the transmission. The UE receives a first repetition of the transmission in a first slot based on single frequency network (SFN) operation using at least one configuration that is different from a configuration used for receiving a second repetition in a second slot based on non-SFN operation. The UE optionally determines, based on the indication, whether repetitions within the multiple repetitions of the transmission are transmitted by the base station based on the SFN operation or the non-SFN operation.

Abstract: Apparatus, methods, and computer-readable media for facilitating cross-carrier beam association are disclosed herein. An example method for wireless communication at a UE includes receiving, from a base station, an indication of a cross-carrier beam association associated with a first carrier and a second carrier different than the first carrier. The example method also includes determining an association between a first set of beams of the first carrier and a second set of beams of the second carrier based on the indication of the cross-carrier beam association. Additionally, the example method includes receiving on the first set of beams and the second set of beams based on the determined cross-carrier beam association.

Abstract: A user equipment (UE) may receive a downlink control information (DCI) including an antenna port field and a transmission configuration indication (TCI) field for scheduling a physical downlink shared channel (PDSCH). The TCI field may indicate that two or more reference signals apply to two or more demodulation reference signal (DMRS) ports across all resource blocks and symbols for the PDSCH for at least one transmission layer of the PDSCH. The antenna port field may indicate a plurality of indicated DMRS ports. The UE may map two or more DMRS ports of the indicated DMRS ports to at least one transmission layer of the PDSCH. The UE may receive the at least one transmission layer of the PDSCH as a single-frequency-network (SFN) transmission based on the two or more reference signals and the two or more DMRS ports.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit beam information, associated with the UE, during a random access channel (RACH) procedure and while in an inactive mode or in an idle mode. The UE may remain in the inactive mode or in the idle mode after transmitting the beam information. Numerous other aspects are provided.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a downlink control information (DCI) indicating two or more transmission configuration indication (TCI) states for a physical downlink shared channel (PDSCH). The UE may differentiate that the two or more TCI states apply to all demodulation reference signal (DMRS) ports or all transmission layers across all resource blocks and symbols for the PDSCH from TCI states that apply to different sets of DMRS ports or different sets of resource blocks or symbols. The UE may generate a composite quasi-co-location (QCL) based on the two or more TCI states in response to the differentiating. The UE may receive the PDSCH based on the composite QCL.

Abstract: Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for performing rate matching when resources for a physical downlink shared channel (PDSCH) overlap with resources of a control resource set (CORESET) in which a physical downlink control channel (PDCCH) that scheduled the PDSCH. As used herein, rate matching generally refers to the process of repeating or puncturing bits on a transport channel.
