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:
Methods, systems, and devices for wireless communication are described. The method may include receiving an UL grant for each CC of a plurality of CCs. In an aspect, each UL grant may include a number of transport blocks (TBs) assigned to each CC. The method may further include sorting CCs among the plurality of CCs as a function at least in part based on the number of TB for each of the CCs, and transmitting one or more packet data units (PDUs) using a subset of CCs of the plurality of CCs. In an aspect, the subset of CCs may be based at least in part on the sorting, and any CC of the plurality of CCs in which only medium access control (MAC) padding PDUs would be transmitted may not be included in the subset of CCs.
Abstract:
Disclosed are methods and apparatus for rejecting unreliable downlink (DL) transmit power control (TPC) commands in windup mode. In one aspect, the method includes receiving by a user equipment (UE) a plurality of DLTPC commands from a base station, analyzing on one or more transmitted uplink (UL) TPC commands, detecting a windup mode based on the one or more DLTPC and ULTPC commands, and rejecting one or more DLTPC down commands in the windup mode.
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 perform, to a first base station and via a first radio frequency (RF) chain associated with a first subscription, a first uplink transmission based at least in part on one or more of an uplink carrier aggregation capability of the UE or an uplink multiple-input multiple-output (MIMO) capability of the UE. The UE may perform, to the first base station or to a second base station, and via a second RF chain associated with a second subscription and configured to operate simultaneously with the first RF chain, a second uplink transmission based at least in part on one or more of the uplink carrier aggregation capability of the UE or the uplink MIMO capability of the UE. Numerous other aspects are described.
Abstract:
Certain aspects of the present disclosure provide techniques for sending uplink control information. A method that may be performed by a user equipment (UE) includes receiving an uplink grant for transmission on a plurality of physical uplink shared channels (PUSCHs), the plurality of PUSCHs being located on different component carriers (CCs); identifying one or more PUSCHs of the plurality of PUSCHs on which uplink control information (UCI) can be transmitted in a slot; assigning PUSCH data to the one or more identified PUSCHs on which the UCI can be transmitted before assigning PUSCH data to remaining PUSCHs of the plurality of PUSCHs; and transmitting the UCI and the PUSCH data in the slot on the assigned PUSCHs.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, using a first subscription of the UE, a first communication connection associated with a first service. The UE may establish, using a second subscription of the UE, a second communication connection associated with a second service. The UE may operate in a dual subscriber identity module (SIM) dual active (DSDA) mode based at least in part on establishing the first communication connection and establishing the second communication connection. The UE may perform an action to maintain concurrent services, including the first service and the second service, while operating in the DSDA mode. Numerous other aspects are described.
Abstract:
Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives, from a network entity, after transmitting at least a first repetition of a physical uplink control channel (PUCCH) transmission according to a first repetition factor, a dynamic indication of a second repetition factor to apply for transmitting the same PUCCH transmission. The UE determines an application time of the second repetition factor based on at least a timing of a last complete or partial transmission instance of the PUCCH transmission. The UE transmits, to the network entity, one or more additional repetitions of the PUCCH transmission based, at least in part, on the determined application time of the second repetition factor.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, to a first base station and via a first radio frequency (RF) chain, at least a portion of a first uplink transmission associated with a first priority. The UE may receive, from the first base station or from a second base station and during the first uplink transmission, a physical downlink control channel (PDCCH) grant for a second uplink transmission associated with a second priority higher than the first priority. The UE may cancel a remaining portion of the first uplink transmission based at least in part on receiving the PDCCH grant for the second uplink transmission. The UE may perform, to the first base station or to the second base station and via a second RF chain, the second uplink transmission. Numerous other aspects are described.
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.
