摘要： Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may use multiple subscriber identification modules (SIMs) in dual-SIM dual-active (DSDA) communications. A DSDA UE may support identification of a set of available radio frequency (RF) resources for communications, where the set of available RF resources include multiple RF components (e.g., transmit/receive antennas), RF baseband resources (e.g., processing resources that support processing and decoding of transmissions), or combinations thereof. The set of available resources may be shared between multiple SIMs, and the UE may identify different resource partitions of the set of available resources, with different resource partitions used to provide concurrent communications of both the first SIM and the second SIM based on parameters of each SIM.

摘要： Methods, systems, and devices are described for transmitting scheduling requests for uplink transmission resources following a handover. A user equipment (UE) may determine that a handover from a first base station to a second base station has occurred, and may implement one or more processes to enhance efficiency in communications following the handover. A UE, for example, may wait for successful acquisition and/or derivation of timing information from a base station before attempting to schedule uplink resources with the base station.

摘要： Methods, systems, and devices are described for wireless communication at a base station. A base station may identify a service type of a mobile device (e.g., voice, web-browsing, or video download). The base station may then determine handover or measurement parameters for the mobile device based on the service type. The base station may also determine a performance metric of the service type. The base station may then adjust the set of parameters based at least in part on the performance metric. In some cases, the base station may select a measurement configuration based on the adjusted parameters.

摘要： Methods, systems, and devices are described for call setup (e.g., VoLTE) for a wireless communication device. During a call setup procedure, the device may implement a “keep alive” mechanism to maintain an RRC connection established as part of the call setup procedure. The “keep alive” mechanism may be configured to insert some padding traffic (e.g., dummy packets) to maintain the RRC connection, for example, by restarting the network RRC connection release timer to prevent its expiration and release of the RRC connection during call setup.

摘要： Systems, methods, and apparatuses for improved traffic management in wireless communications are disclosed. Aspects of the present disclosure provide real-time radio frequency (RF) assessments to a network by leveraging measurement reports from user equipment (UE). In some aspects, the network utilizes the real-time RF assessments based on the measurement reports to adjust one or more idle-mode parameters of the UE and assign priorities to a plurality of frequencies based on their respective coverage area and/or propagation characteristics. In one example, the priority assignments for two or more of the plurality of frequencies may be inversely proportional to their respective coverage areas, so as to push UEs with acceptable signal quality to frequencies with smaller coverage area, thereby releasing frequencies with greater coverage area for UEs that are near or at the edge of the effective range of the base station.

摘要： Methods, systems, and devices are described for data transmission using header compression techniques that may include dropping all of a portion of a payload for one or more Protocol Data Units (PDUs). A wireless communications device may determine that a robust header compression (RoHC) mode is in an initialization and refresh (IR) state, indicating a full Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU), including complete header information, is to be transmitted. The wireless communications device may identify that a payload of at least part of a media frame is to be transmitted in the IR state, and drop at least part of the payload when a probability of segmenting the payload during transmission in the IR state exceeds a threshold.
