Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A user equipment (UE) may have data in a buffer for uplink (UL) transmission. The UE may transmit a buffer status report (BSR) indicating the amount of data. The BSR may fail or a base station may not grant sufficient resources for transmission of the data. A BSR failure condition may be based on a radio link control (RLC) operating mode of the data. For example, the data may be an acknowledgement (ACK) for an acknowledged mode (AM) DL transmission. In this case, the UE may initiate a BSR retransmission (Retx-BSR) timer and determine whether any duplicate transmissions have been received. The data may also be associated with an unacknowledged mode (UM), and the BSR failure condition may include waiting for a time interval that is less than the Retx-BSR time interval. When the BSR failure condition is satisfied, the UE may transmit a scheduling request to the base station.

Abstract: 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.

Abstract: 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.

Abstract: Methods, systems, and devices for managing wireless communications are described. In one embodiment, information relating to a scheduling request performance of a first set of one or more user equipments (UEs) may be compiled, and at least a subset of the information may be transmitted to trigger an identification of an adjustment of an uplink power control setting of a second set of one or more UEs. In another embodiment, information to trigger an identification of an adjustment of an uplink power control setting for transmitting scheduling requests may be received from each of a first plurality of UEs. The information may be analyzed, and a power adjustment may be identified for the uplink power control setting for at least one of a second plurality of UEs. The identified power adjustment may then be transmitted to the at least one of the second plurality of UEs.

Abstract: User equipment (UE) transmits an access response to a random access procedure (RACH) preamble message to acquire an uplink grant from a node of a wireless communication system. The access response provides an uplink grant to the UE for a request for authorization to transmit uplink data to the node. In response to determining that the access response message provides an uplink grant sufficient to empty the UE's data buffer, the UE transmits the request for authorization including the uplink data to the node. The UE can then terminate the RACH procedure without requiring any subsequent uplink grant from the node, having accomplished successful data transmission using the request for authorization.
