In some aspects, a user equipment (UE) may receive, from a first transmit receive point (TRP), a downlink control information (DCI) communication, the UE being included in a multi-TRP configuration with the first TRP and a second TRP. The UE may determine information unique to the first TRP. The information unique to the first TRP may be at least one of associated with the DCI communication or included in the DCI communication. The UE may generate a downlink scrambling sequence initialization code, associated with the first TRP, based at least in part on the information unique to the first TRP. The UE may generate a downlink scrambling sequence, associated with the first TRP, based at least in part on the downlink scrambling sequence initialization code associated with the first TRP.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to semi-persistent configuration of reference signals (RSs), such as measurement reference signals (MRSs) for beam refinement. An example method generally includes transmitting, to a user equipment (UE), a reference symbol (RS) configuration, wherein transmitting the RS configuration is independent of activating RS training for the UE, transmitting, to the UE, a message indicating an activation of RS training subsequent to transmitting the RS configuration, transmitting RSs to the UE periodically based on the RS configuration, and receiving, from the UE, measurement reports based on the transmitted RS.

Abstract: A first apparatus may determine a first schedule associated with the one or more repetitions of the control information on the control channel based on the first information. The first apparatus may receive, from the network, at least one of the one or more repetitions of the control information on the control channel based on the first schedule, wherein the control information indicates a second schedule associated with a random access response (RAR) on a data channel. The first apparatus may receive, from the network, the RAR on the data channel based on the second schedule.

Abstract: Aspects of the present disclosure relate to techniques for multibeam PDCCH monitoring during CDRX operations. A BS may determine a configuration of one or more beams for a UE to monitor for receiving a downlink control channel from the BS, wherein the configuration is based, at least in part, on a monitoring window since the subframe in which the downlink control channel (e.g., PDCCH), indicates an initial UL, DL, or SL use data transmission for the UE. The BS may transmit, to the UE, an indication of the configuration. A UE may perform corresponding operations and may monitor one or more beams based on the received configuration.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may measure a first reference signal, associated with a frequency band of a long term evolution (LTE) system, and a second reference signal associated with a frequency band of a new radio (NR) system. The frequency band of the NR system may overlap the frequency band of the LTE system. The UE may determine first channel state feedback, associated with the frequency band of the LTE system, and second channel state feedback, associated with the frequency band of the NR system, based at least in part on the first reference signal and the second reference signal, respectively. The UE may report the first channel state feedback or the second channel state feedback in uplink control information (UCI). Other aspects are provided.
