Abstract: This disclosure provides systems, methods and apparatuses for measurement of cells and determination of a non-standalone (NSA) coverage status using an NSA coverage database. The NSA coverage database may indicate candidate frequencies of New Radio (NR) cells that provide NSA coverage corresponding to a given Long Term Evolution (LTE) serving cell. The NSA coverage database may also indicate whether a system information block 1 (SIB1) has been previously received on a candidate frequency. The user equipment (UE) may perform measurement of candidate frequencies using the NSA coverage database, and may identify cases where a cell not providing NSA coverage has a same candidate frequency as a cell providing NSA coverage using the indication of whether SIB1 has been previously received on a candidate frequency.

Abstract: Aspects are provided which allow a UE to manage a number of antennas in adaptive receive diversity (ARD) based on packet error rate (PER). The UE measures a downlink PER and determines a number of antennas for receiving a downlink transmission based on the measured, downlink PER. The UE measures downlink PER during switching from a fallback state to a steady state in an ARD state machine, and the UE changes a size of a fallback window in the ARD state machine based on the measured, downlink PER. The UE also disables switching from the steady state to the fallback state based on the measured downlink PER. As a result, a balance between UE reception performance and power savings is maximized and improved downlink data throughput is achieved.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a first service associated with a first subscriber identification module (SIM), the first service having a first priority. The UE may identify at least one re-prioritization condition that is satisfied, wherein the at least one re-prioritization condition is associated with at least one of the first service or a second service associated with a second SIM, the second service having a second priority that is lower than the first priority. The UE may adjust, based at least in part on the at least one re-prioritization condition being satisfied, the second priority, wherein the adjusted second priority is higher than the first priority. The UE may perform a communication corresponding to the second service based at least in part on the adjusted 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 receive, at a packet data convergence protocol (PDCP) layer, a packet having a PDCP sequence number. The UE may determine whether the received packet, having the PDCP sequence number, satisfies one or more reordering criteria. The UE may discard, before an expiration of a reordering timer, the received packet based at least in part on the determination of whether the received packet satisfies the one or more reordering criteria. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink reference signal configuration indicating antenna switching for transmitting an uplink reference signal of a first radio access technology (RAT). The UE may report a rank for a downlink communication of a second RAT, wherein the rank is in accordance with an upper bound, for the rank, associated with mitigating downlink performance degradation on the second RAT due to the antenna switching. Numerous other aspects are provided.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE) or component thereof. The apparatus may be configured to transmit to a base station a first request to transmit data in a buffer. The apparatus may be further configured to transmit to the base station a second request to transmit the data in the buffer in absence of a grant in response to the first transmit request. The apparatus may be further configured to remain awake for at least a portion of a scheduled discontinuous reception (DRX) sleep state following the transmission of the second request.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify radio access technology (RAT) state information associated with the UE, the RAT state information including an indication of whether the UE is operating in a steady state or is operating in a transition state. The UE may adapt a codec rate associated with an application of the UE based at least in part on whether the UE is operating in the steady state or is operating in the transition state. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a first timer associated with a first antenna and a second timer associated with a second antenna. The UE may identify an expiration of the first timer associated with the first antenna. The UE may determine, based at least in part on the identified expiration of the first timer, whether a remaining time of the second timer associated with the second antenna is less than a timer threshold. The UE may select, based at least in part on the determination that the remaining time of the second timer is less than the timer threshold, the second antenna. Numerous other aspects are provided.
