Abstract: Methods, systems, and devices for wireless communication are described in which a user equipment (UE) may transmit one or more uplink communications to multiple transmission-reception points (TRPs). Transmission parameters for each repetition may be based on parameters (e.g., a number of antenna ports, a spatial domain filter or beam, a rank or number of layers, or any combinations thereof) that are determined from an indication of whether the repetitions are to use different sounding reference signal (SRS) resource sets, and indicated SRS resource of each SRS resource set. The indication may include a same number of bits regardless of whether one SRS resource set is used or multiple SRS resource sets are used, and may be based on a prior configuration of the UE.

Abstract: This disclosure provides methods for transmissions and retransmissions over a configured grant (CG) physical uplink shared channel (PUSCH) and for transmissions over physical uplink control channel (PUCCH) resources in multi-transmission and reception point (TRP) deployments. A user equipment (UE) may receive signaling configuring a first set of power control parameters and a second set of power control parameters for a CG-PUSCH resource. Additionally or alternatively, the UE may receive signaling activating a first closed-loop power control operation and a second closed-loop power control operation for a PUCCH resource.

The configuration may indicate transmission parameters associated with different symbols such as sub-band full duplex (SBFD) symbols and non-SBFD symbols. For example, the transmission parameters may indicate power control parameters (e.g., a received power target value, a power control factor value, a closed-loop power control value) and a unified transmission configuration indicator (TCI) (e.g., a joint uplink and downlink TCI state, separate uplink and downlink TCI states). The UE may transmit uplink transmissions to the BS, in accordance with the transmission parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may support repetition of physical downlink control channels (PDCCH) and handling a combined PDCCH candidate associated with multiple search space sets. For example, a UE may combine a first PDCCH candidate corresponding to a first search space set and a second PDCCH candidate corresponding to a second search space set to form a combined PDCCH candidate. The UE may decode the combined PDCCH candidate based on one or more factors, for example, such as a blind decoding PDCCH candidate threshold. As a result, the UE may decode the combined PDCCH candidate in addition to decoding of individual PDCCH candidates, thereby providing increased flexibility for downlink control information (DCI) and improving the reliability of PDCCH.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for independent scheduling by a first transmission and reception point (TRP) and a second TRP for a user equipment (UE) operable in a multiple TRP (mTRP) mode. A semi-static time division duplexing (TDD) pattern may indicate a set of downlink symbols, a set of uplink symbols and a set of flexible symbols. A portion of the flexible symbols may be dedicated for communications with the first TRP, and the second TRP may not use the portion of the flexible symbols dedicated for communications with the first TRP. The first UE may operate in the mTRP mode in the semi-static downlink symbols or uplink symbols and operate in a single TRP mode in the portion of the flexible symbols dedicated for communications with the first TRP.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for linking downlink control information candidates across multiple transmission and reception points (TRPs) with cell discontinuous transmission (DTX) operations. A user equipment (UE) may determine a linkage status of linked downlink control information candidates across multiple TRPs with DTX operations. The UE may determine the linkage status based on a DTX status of the first TRP or a DTX status of the second TRP. When the DTX status of the first TRP or the second TRP is activated, the UE may determine the linkage status is a broken linkage. The UE may determine the linkage status as the broken linkage if one of the downlink control information candidates is within an inactive duration of a DTX cycle. The UE may determine the linkage status as the maintained linkage or broken linkage based on DCI format.

Abstract: Methods, systems, and devices for wireless communications are described for configuration of multiple transmission configuration indicator (TCI) states and selection of a particular TCI state or TCI states for different instances of scheduled periodic communications between a user equipment (UE) and one or more transmission-reception points (TRPs) or base stations. A UE may receive, from a network entity, control signaling identifying two or more TCI states that are to be applied to communications of one or more channels subsequent to a determined time. The network entity may also provide a periodic communication configuration with a series of resource allocations for periodic communications, and a selection indication for which of the two or more TCI states are to be selected for the periodic communications. The UE may communicate via the one or more channels according to one or more TCI states based on the selection indication.

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.
