Abstract: Some techniques and apparatuses described herein enable synchronization of a user equipment (UE) identifier between a UE and a base station upon UE identifier reallocation, which enables the UE to use preconfigured uplink resources to reduce latency, reduce signaling overhead, and/or the like. For example, some techniques and apparatuses described herein enable the UE to use preconfigured uplink resources when a UE identifier reallocation occurs between preconfigured uplink resource configuration and use of the preconfigured uplink resources by the UE to transmit uplink data.

Abstract: Certain aspects of the present disclosure provide techniques for an enhanced query and response message for a recommended bit rate for uplink and/or downlink streaming. The techniques generally include generating a query message indicating a requested data rate for streaming services, wherein the requested data rate is indicated via a bit rate field and one or more additional bits, and sending the query message to a base station.

Abstract: The present disclosure relates to methods and devices for a handover procedure which may include a user equipment (UE), first base station, and a second base station. In one aspect, the UE can receive an indication to handover from the first base station to the second base station. The UE may then establish a connection with the second base station. In another aspect, the UE can maintain a connection with the first base station over a period of time during the handover. The UE can also communicate with the first base station and the second base station during the period of time based on a time division multiplexing (TDM) pattern. The TDM pattern can comprise a pattern of subframes for communicating with the first and second base station. In another aspect, the UE can release the connection with the first base station at the end of the period of time.

Abstract: Aspects of the disclosure relate to a method of operating a user equipment (UE) for wireless communication with a network. In some aspects, the UE obtains a medium access control (MAC) control element (CE) from a network. The MAC CE may be configured to indicate any one of a plurality of state transition actions for a secondary cell. The UE transitions to a secondary cell dormant state when a state transition action indicated by the MAC CE includes a transition to the secondary cell dormant state. The UE operates in the secondary cell dormant state.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving service recovery using communications systems operating according to new radio (NR) technologies. For example, a method may include receiving an uplink transmission from a user equipment (UE) with a Cell Radio Network Temporary Identifier (C-RNTI), determining the C-RNTI lacks context at the network entity, and signaling, in response to the determination, an indication of an immediate C-RNTI release to the UE.

Abstract: The present disclosure provides user equipment power consumption and secondary cell (SCell) activation latency reductions in wireless communication systems. For example, a UE may determine that a secondary cell activation condition has been satisfied. The UE may further transition to a secondary cell activated state based on determining that the secondary cell activation condition has been satisfied, the secondary cell activate state corresponding to a dormant SCell state. The UE may operate at least in the dormant SCell state.

Abstract: A method of wireless communication by a user equipment (UE) without a radio resource control (RRC) connection to a base station includes receiving system information from the base station and transmitting a data communication to the base station over a control plane without establishing an RRC connection with the base station. A UE in an RRC suspended state may transmit a data communication to the base station over a user plane without resuming an RRC connection with the base station. The data communication may comprise data and UE identity information and/or a cause indication. A base station may indicate resources in the system information for the transmission of the data communication information and receive the data communication over the control plane without establishing an RRC connection with the UE or over a user plane without resuming an RRC connection with an RRC suspended UE.

Abstract: A method includes sending communication data from a user equipment (UE) to a base station (eNB) during a random access procedure prior to establishment of a radio resource control (RRC) connection between the UE and the base station. Methods may allow a UE to use a message 1 (Msg1) communication or a message 3 (Msg3) communication to send data to a base station prior to the establishment of the RRC connection between the UE and the base station. Other aspects, embodiments, and features are also claimed and described.
