Abstract: A plurality of scheduled entities, such as transmission reception points (TRPs), may each transmit at least one TRP-specific beam failure detection reference signal (BFD-RS) having a corresponding TRP identifier (ID) to a scheduled entity. The scheduled entity may be configured with at least one TRP-specific medium access control (MAC) parameter. The scheduled entity may receive the TRP-specific BFD-RSs and respective TRP IDs associated therewith. The scheduled entity may measure each BFD-RSs and count beam failure instances associated with each TRP ID. The scheduled entity may transmit a beam failure recovery request (BFRQ) associated with the respective TRP ID in response to a predetermined quantity of respective TRP-specific BFD-RS measurements of at least one of the respective TRP-specific BFD-RSs being less than a predetermined value. A scheduling entity may receive the BFRQ, where the at least one TRP-specific MAC parameter was used to trigger the BFRQ.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may receive a control message indicating a first (MCS) value and a first resource associated with a first codeword and a second MCS value and a second resource associated with a second codeword. The UE may monitor the first resource for the first codeword in accordance with one or more first parameters determined by indexing a first MCS table using the first MCS value. The UE may monitor the second resource for the second codeword in accordance with one or more second parameters determined by indexing one of the first MCS table using the second MCS value or a second MCS table using the second MCS value. The UE may decode the first codeword and the second codeword based on monitoring the first resource and the second resource.

Abstract: This disclosure provides systems, methods and apparatuses for uplink channel transmission for multiple transmit receive points (TRPs). In one aspect, a user equipment (UE) resolves overlapping physical uplink control channels (PUCCHs) in a slot or overlapping PUCCH(s) and PUSCH(s) that are mapped to a same TRP in a multi-TRP scenario and that are mapped to two or more different TRPs in the multi-TRP scenario. For example, in a multi-TRP scenario that includes two TRPs, the UE may eliminate overlap of these uplink channels for each of the two TRPs individually and may additionally eliminate overlap of these uplink channels between the two TRPs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first message indicating a first set of parameters associated with time domain resource allocation (TDRA) information for a first quantity of shared channels. The UE may receive a second message (e.g., downlink control information (DCI)) scheduling a set of shared channels, a second quantity of the set of shared channels exceeding the first quantity. The set of shared channels may include a first subset of shared channels corresponding to the first quantity, and a second subset of shared channels including additional shared channels. In addition, the UE may determine a second set of parameters for the second subset based on the first set of parameters, where the UE and a network entity may communicate the first subset using the first set of parameters and the second subset using the second set of parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform beam sweeping for a physical uplink channel within time domain windows or across time domain windows based on a time domain window index. In cases where frequency hopping is enabled, the UE may transmit uplink repetitions and demodulation reference signals (DMRSs) across two frequency hops during two consecutive time domain windows using a first transmit beam, and may then follow up with transmissions across two frequency hops during the next two consecutive time domain windows using a second transmit beam. Or, the UE may transmit uplink repetitions and DMRSs in a first frequency hop with first and second transmit beams during two respective consecutive time domain windows, and may transmit in a second frequency hop with the first and second transmit beams during the next two respective consecutive time domain windows.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for handling hybrid automatic repeat request (HARQ) processes with discontinuous reception (DRX) operations. A user equipment (UE) may use timers to maintain an ON duration in DRX. The UE may receive, via downlink control information (DCI), an indication of a feedback transmission opportunity (TxOP) for a HARQ process. The UE may activate a timer at the end of the TxOP regardless of whether the UE transmits feedback in the TxOP to ensure that the UE remains active. In some implementations, a base station may provide the UE with multiple opportunities to transmit a feedback message. The UE may reactivate a timer after each feedback TxOP for the same HARQ process or may activate the timer after the first feedback TxOP and may refrain from activating the timer after subsequent feedback TxOPs for the HARQ process.

Abstract: Aspects described herein relate to beam sweep based semi-persistent signaling (SPS) or configured grant (CG) activation. In one aspect, a network entity may determine a beam sweep pattern for at least one of a SPS based downlink periodic transmission, an uplink control transmission for the SPS based downlink periodic transmission, or a CG based uplink periodic transmission. The network entity may further transmit an indication including the beam sweep pattern to a user equipment (UE). In another aspect, a UE may receive a beam sweep pattern for at least one of a SPS based downlink periodic transmission, an uplink control transmission for the SPS based downlink periodic transmission, or a CG based uplink periodic transmission from a network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message, the DCI message including at least a first field and a second field, the first field indicating a request for Type 3 hybrid automatic repeat request (HARD) acknowledgment (HARQ-ACK), the second field indicating a physical downlink shared channel (PDSCH) communication is not scheduled when a value of the second field includes: all zeros if resource allocation Type 0 is configured, all ones if resource allocation Type 1 is configured, or all ones or all zeros in a dynamic switch configuration. The UE may transmit the Type 3 HARQ-ACK based at least in part on the DCI message. Numerous other aspects are described.
