Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for applying a beam switch interruption time across one or more active component carriers. In some cases a UE may be able to detect an actual overlap condition in which two physical downlink control channels (PDCCHs) monitoring occasions with different beam parameters overlap in time or a soft overlap condition in which a distance between the two PDCCH monitoring occasions in time is less than a threshold value; and to apply a prioritization rule to determine which of the PDCCH monitoring occasions to monitor for PDCCHs in response to detect the actual overlap or a soft overlap (e.g., almost immediately in contact in time or the gap is very small compared to the slot size).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, on a downlink control channel and a first beam, first downlink control information (DCI), wherein the first DCI identifies a second DCI that is carried on a downlink shared channel; and receive multiple repetitions of the second DCI on the downlink shared channel on a plurality of second beams.

Abstract: Aspects described herein relate to receiving, from a base station, a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, receiving, from the base station, the one or more repetitions of the downlink control channel, and combining the one or more repetitions of the downlink control channel to decode the downlink control channel. In another aspect, the network can transmit, to a user equipment (UE), a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, and transmitting, to the UE, the one or more repetitions of the downlink control channel over the resources.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: Wireless communication devices, systems, and methods related to mechanisms for transmitting and receiving reference signals in a high-speed train (HST) single frequency network (SFN). A base station (BS) determines a first frequency pre-compensation value for a reference signal transmitted via a first transmission and reception point (TRP) and a second frequency pre-compensation value for a reference signal via a second TRP. The BS notifies a user equipment (UE) of the first and second pre-compensation values through at least one of the TRPs. The BS applies the first pre-compensation value to the reference signal via the first TRP and the second pre-compensation value to the reference signal via the second TRP. The UE adjusts its tracking loop for the reference signal based on the pre-compensation values, reducing estimation and/or search overhead at the UE.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDDCH includes a first DCI part and the PDSCH includes a second DCI part. In an example, a TBS associated with the PDSCH may be determined (e.g., either by factoring or ignoring resource elements associated with the second DCI part). In another example, the PDSCH may be associated with a modulation scheme with a constellation having constellation points, whereby the second DCI part in the PDSCH is restricted to a subset of the constellation points. In another example, rate-matching may be performed for one or more resource elements of the second DCI part.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first control signal in a control resource set (CORESET) from a first transmit receive point (TRP), wherein the first control signal includes a set of control channel elements (CCEs) to encode a first portion of a first downlink control information (DCI) message and/or a first portion of a second DCI message. The UE may receive a second control signal in the CORESET from a second TRP, wherein the second control signal includes the set of CCEs to encode a second portion of the first DCI message and/or a second portion of the second DCI message. Numerous other aspects are provided.

Abstract: A UE may determine that two or more resources on two or more beams from a base station have phase continuity. The UE may determine, based on the two or more resources on the two or more beams having the phase continuity, a joint channel information associated with the two or more beams using individual measurements respectively corresponding to the two or more beams. The UE may then transmit, to the base station, a group-based beam report including the joint channel information. The base station may provide the UE with an indication that the two or more resources on the two or more beams from the base station have phase continuity. The base station may receive the group-based beam report from the UE based on the indication, and the base station may configure communication with the UE on a joint channel based on the group-based beam report.

Abstract: This disclosure provides methods, devices and systems for beamforming in wireless communications. Some implementations more specifically relate to beamforming configurations for multicast communications. A transmitting device may transmit multicast data to multiple receiving devices, concurrently, via a physical downlink shared channel (PDSCH). The PDSCH may be preceded by a physical downlink control channel (PDCCH). The PDCCH may provide scheduling information for the PDSCH, including a multicast beam associated with the PDSCH and a timing offset or delay between the PDCCH and the PDSCH. A receiving device may determine that the PDSCH contains multicast data based on an indication in the PDCCH. To receive the PDSCH, each receiving device may tune its antennas in a direction of the scheduled multicast beam or a default beam based on the delay between the PDCCH and the PDSCH.
