Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or base station. In one aspect, the apparatus may receive a channel state information (CSI) report configuration via radio resource control (RRC) signaling, the CSI report configuration including at least one of a channel measurement resource (CMR) resource setting, an interference measurement resource (IMR) resource setting, or a report quantity parameter. The apparatus may also determine a downlink receive beam of one or more downlink receive beams based on the CSI report configuration. The apparatus may also communicate with a base station via the downlink receive beam based on the determined downlink receive beam. Additionally, the apparatus may calculate a signal-to-interference-plus-noise ratio (SINR) quantity associated with a plurality of downlink transmit beams. The apparatus may also decode the CSI report configuration.

Abstract: A first apparatus may be implemented as a user equipment (UE) or a component thereof. The first apparatus may be configured to receive a pre-grant message from a base station on a wireless channel. The first apparatus may be further configured to determine an interference level associated with the wireless channel. The first apparatus may then indicate the interference level to the base station in response to the pre-grant message. A second apparatus may be implemented as a base station or a component thereof. The second apparatus may be configured to transmit a pre-grant message to a UE on a wireless channel. The second apparatus may be further configured to detect for an acknowledgement (ACK) message responsive to the pre-grant message from the UE. The second apparatus may then determine an interference level associated with the wireless channel proximate to the UE based on detecting for the ACK message.

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: Certain aspects of the present disclosure provide techniques for feedback compression. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving, from a base station, a configuration to be used for compressing one or more measurements corresponding to at least one reference signal using an artificial intelligence (AI) encoder; receiving the at least one reference signal; and transmitting a codeword to the base station, the codeword being associated with a compression of the one or more measurements in accordance with the configuration.

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.
