Abstract: A gain factor is used for calculating one transmit power relative to another transmit power. For example, in UMTS high speed uplink packet access, a gain factor called βed is employed for transmission associated a given enhanced transport format combination indicator (E-TFCI). Conventionally, a gain factor to be used for a given E-TFCI can be determined via interpolation between two of the reference E-TFCIs to reduce signaling overhead. However, certain network configurations may result in one or more of the reference E-TFCIs that could be otherwise be used according to conventional techniques being outside of a valid range. In the event such a sub-optimal configuration occurs, interpolation and/or extrapolation schemes based on at least one reference E-TFCIs that is within and/or or is not within the valid range are used to calculate a gain factor for a given E-TFCI.

Abstract: Methods, systems, and devices for wireless communications are described that provide for receive chain selection at a user equipment (UE) with efficient switching between a reduced number of receive chains and an increased number of receive chains for downlink communications based on conditions at the UE. A UE may adaptively adjust the number of active receive chains based on downlink grant activity, channel conditions, network parameters, or any combinations thereof. An estimator block at the UE may determine to adjust the number of receive chains based on a number of downlink grants within one or more time periods. In some cases, grants for an amount of data that exceeds a threshold may be qualified in order to be counted at the estimation block. Further, a transient state may be provided where the UE may maintain a higher number of active receive chains until UE feedback is provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for managing scheduling requests (SRs) in a user equipment (UE) that supports a split data radio bearer (DRB). In some aspects, the UE may trigger a first SR for a first communication link and a second SR for a second communication link in response to determining that a first amount of data in the UE data buffer is greater than a first threshold. The UE may transmit the first SR to a first base station (BS) via the first communication link. Prior to transmission of the second SR, the UE may determine whether a second amount of data in the UE data buffer is less than a second threshold. The UE may cancel the second SR in response to the second amount of data in the UE data buffer being less than the second threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first service, having a first priority during a time interval, associated with a first subscriber identification module (SIM), and a second service, having a second priority during the time interval, associated with a second SIM of the UE, the first priority having a higher priority than the second priority. The UE may identify a first type of communication associated with the second SIM. The UE may adjust, based at least in part on the first type of communication, at least one of the first priority or the second priority during the time interval. The UE may perform a communication in accordance with the adjusted at least one of the first priority or the second priority. 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 to initiate a random access channel (RACH) procedure with a base station (BS). The UE may determine, based at least in part on determining to initiate the RACH procedure, whether a timing alignment timer, associated with a timing alignment of the UE and the BS, is expired. The UE may initiate the RACH procedure using the timing alignment based at least in part on determining that the timing alignment timer is not expired. Numerous other aspects are provided.

Abstract: Aspects relate to random access channel procedures. In some examples, if a user equipment (UE) has not successfully received a random access channel (RACH) downlink message prior to the end of a random access window for a first RACH attempt, the UE may elect to proceed with a second RACH attempt. For example, the UE may determine whether there are any remaining downlink symbols available during the random access window to receive the RACH downlink message. If not, the UE may retransmit a physical RACH (PRACH) preamble.

Abstract: A UE may obtain an indication of a first subset of PRACH resources in a set of PRACH resources, the first subset of PRACH resources having a set of channel metrics that is greater than or equal to a first threshold value, select a first PRACH resource from the first subset of PRACH resources based on a first set of channel metrics of the first PRACH resource or a first RO associated with the first PRACH resource, and transmit a RACH message to a network node in the first RO. The UE may evaluate the multiple qualifying SSBs/CSI-RSs and select one SSB/CSI-RS among the qualifying SSBs/CSI-RSs based on a scheduling opportunity of the associated ROs and a power usage on the UE side.
