Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration. The UE may transmit, via a scheduling request resource of a second logical channel that has a valid scheduling request configuration, a scheduling request for resources to transmit the data buffered for transmission via the first logical channel. 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:
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:
Aspects are provided allowing a MSIM UE to transmit a controlled pattern of fake HARQ-ACK and a controlled RLC status report in response to un-decoded data transmissions from a base station, while suspending SRS antenna switching during performance of an activity in a different network subscription, in order to relieve MCS penalties in response to such suspension while minimizing RLC holes. The UE sends a plurality of SRSs to a base station in a first network using a first SIM of the UE, where each of the SRSs is sent using a different antenna. The UE suspends SRS transmission from the different antennas while performing an activity in a second network using a second SIM of the UE. The UE sends a HARQ-ACK to the base station while the SRS transmission is suspended in response to at least one of a plurality of un-decoded data transmissions from the base station.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate (410) a first service, having a first priority during a time interval, associated with a first subscriber identification module (SIM), and a second service (420), 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 (440) a first type of communication associated with the second SIM. The UE may adjust (450), 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 (460) a communication in accordance with the adjusted at least one of the first priority or the second priority.
