Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques and devices for uplink gap configuration and determination of uplink resources after uplink gap distribution. Certain aspects are directed to an apparatus for wireless communications at a user equipment (UE). The UE may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the instructions may cause the apparatus to obtain, from a base station, an uplink gap pattern (ULGP) configuration indicating a first ULGP associated with a first time window, wherein the first ULGP is indicative of a distribution of one or more uplink slots activated as uplink gaps within the first time window, and wherein the one or more uplink slots are independent from being used for any transmission initiated by the apparatus.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a bandwidth part (BWP) hopping configuration indicating a set of hops for a BWP of the UE. The UE may identify a radio link failure (RLF) during a time period configured by the set of hops. The UE may disable the BWP hopping configuration based at least in part on identifying the RLF. The UE may initiate a random access procedure on a BWP that is associated with the random access procedure. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing a bandwidth of a user equipment (UE). The UE has a narrower bandwidth part (NBWP) that follows a NBWP hopping pattern and allows the UE to hop frequency over time within a larger bandwidth. The UE receives a configuration of one or more NBWP hopping patterns for one or more configured NBWPs, each configured NBWP having a bandwidth less than or equal to a maximum configurable bandwidth of a bandwidth part. The UE determines an active NBWP hopping pattern for an active NBWP of the one or more configured NBWPs. The UE communicates on frequency domain resources for a frequency domain hop indicated by the active NBWP hopping pattern applied to the active NBWP. The UE may receive an indication of whether to switch the active NBWP hopping pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source node in a non-terrestrial network (NTN) providing an NTN cell, measurement reference information regarding one or more measurements, wherein the measurement reference information includes association information including a group identifier for the one or more measurements. The UE may communicate in the NTN cell in accordance with the measurement reference information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a scaling factor for a beam failure detection (BFD) evaluation period associated with a secondary cell group of a set of secondary cell groups. The scaling factor may be determined based at least in part on a number of secondary cell groups included in the set of secondary cell groups. In some aspects, the UE may perform a BFD measurement, associated with the secondary cell group, based at least in part on the scaling factor for the BFD evaluation period. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for processing multi-layer transmissions simultaneously received from multiple network entities. An example method for wireless communications by a user equipment (UE) includes obtaining a first channel matrix for spatially processing multi-layer transmissions from a first network entity received via a first antenna panel at the UE; obtaining a second channel matrix for spatially processing multi-layer transmissions from a second network entity received via a second antenna panel at the UE; and spatially processing one or more multi-layer transmissions from the first and second network entities simultaneously received via the first and second antenna panels at the UE, based on a third channel matrix including entries of the first channel matrix and entries of the second channel matrix.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may receive a configuration from a base station (BS). 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.
