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: This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.

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: In order to improve the selection of search space candidates for a downlink control channel, an apparatus determines a set of decoding candidates of a lower aggregation level for a downlink control channel based on a random selection from a plurality of potential decoding candidates, wherein the plurality of potential decoding candidates are defined from a second set of decoding candidates of a higher aggregation level. The apparatus then attempts to decode the downlink control channel based on determined sets of decoding candidates of different aggregation levels. The downlink control channel may comprise a PDCCH.
