Abstract:
Methods and systems improve performance of a wireless communication device supporting an active communication in a first network on a modem stack associated with a first subscriber identity module. The wireless communication device may detect that a control signal was received on the modem stack associated with the first SIM, identify a percentage of scheduled uplink feedback corresponding to the control signal received on the modem stack associated with the first SIM that will be transmitted on the first network, and determine whether determining whether the identified percentage is less than a threshold. If the identified percentage is that will be transmitted to the first network is less than the threshold, the wireless communication device may ignore operations instructed by the control signal received on the modem stack associated with the first SIM.
Abstract:
Various embodiments for managing carrier transmissions after a tune-away on a wireless communication device may include determining whether a network has received transmissions from a first carrier of a first subscription after completion of the tune-away from the first subscription to a second subscription. In response to determining that the network has not received transmissions from the first carrier, the wireless communication device may determine whether a second carrier of the first subscription is transmitting to the network after completion of the tune-away. In response to determining that the second carrier is not transmitting to the network, the wireless communication device may route transmission from the first carrier to the second carrier.
Abstract:
Aspects related to allocating transmission power in wireless communications are described. It can be determined whether data is to be transmitted on an uplink control channel in one or more upcoming transmission time intervals (TTIs). Based on this determination, transmission power is allocated to an uplink enhanced dedicated channel in the one or more upcoming TTIs. Where uplink control channel data is not to be transmitted in the one or more upcoming TTIs, transmission power that would have been used for the uplink control channels can instead be allocated to the enhanced dedicated channel.
Abstract:
Aspects of the present disclosure provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.

Abstract:
Aspects of mitigating throughput degradation during wireless communication include determining that a first transmission signal fails decoding at a network entity due to transmit (TX) blanking when a user equipment (UE) supports dual subscriber identity module dual active (DSDA) and is operating in hybrid automatic repeat request (HARQ) with incremental redundancy; determining whether a first retransmission signal for the first transmission signal fails decoding at the network entity; and retransmitting the first transmission signal as a new transmission signal when a determination is made that the first retransmission signal for the first transmission signal fails decoding at the network entity.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, based at least in part a determination to transmit one or more packets, a scheduling request (SR) occasion in which to transmit an SR for uplink resources to transmit the one or more packets, the SR occasion occurring prior to a start of a connected discontinuous reception (CDRX) on duration of the UE. The UE may determine whether the SR occasion occurs within a threshold amount of time prior to the start of the CDRX on duration of the UE. The UE may transmit the SR in the SR occasion based at least in part on the determination of whether the SR occasion occurs within the threshold amount of time prior to the start of the CDRX on duration of the UE. Numerous other aspects are provided.
Abstract:
Aspects of the present disclosure provide techniques to enable random access channel (RACH) enhancements over previously known techniques for narrowband (e.g., narrowband Internet-of-Things (NB-IoT) ) communications systems. An example method includes receiving a first allocation of frequency resources for a first period for receiving a downlink (DL) transmission or transmitting an uplink (UL) transmission, and postponing transmission of a random access channel (RACH) by the UE during the period.
Abstract:
In an aspect, this disclosure provides for determining a power imbalance between a first radio frequency (RF) carrier and a second RF carrier of a dedicated physical control channel for uplink transmission, determining whether the power imbalance is greater than a power imbalance threshold, and blocking data transmission on one of the first RF carrier or the second RF carrier when the power imbalance is greater than the power imbalance threshold.
