    Abstract: Aspects of the present disclosure provide methods and apparatus for transmitting an uplink reference signal, receiving a keep alive (KA) command based, at least in part, on the uplink reference signal, and taking one or more actions to perform a handover to a non-serving base station (BS) in accordance with the KA command. Additionally, aspects provide methods and apparatus for receiving an uplink reference signal from a user equipment (UE), measuring the uplink reference signal, and transmitting a KA command to the UE based, at least in part, on the measured uplink reference signal. The KA command may be scrambled by an identifier associated with the UE. Additionally or alternatively, a cyclic prefix (CP) of the uplink reference signal may be longer than a CP of another type of reference signal.

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a service-based cell reselection by a user equipment (UE) in a wireless communication system. The UE may have a service relationship with a particular service. A wireless communication system may provide different types of services via different radio frequencies. The UE may determine which cells to measure for cell reselection to include those that correspond to a service of interest to the UE. In addition to power savings, the UE may experience faster cell reselection for a service. The techniques of this disclosure also may enable a priority-based cell reselection so that the UE can camp on a cell that supports a higher priority service compared to other services supported by the UE.

    CPC classification number: H04W72/1284 ,  H04W72/1231

    Abstract: A user equipment (UE) may receive, at a packet data convergence protocol (PDCP) layer, a service data unit (SDU) including uplink (UL) data to be transmitted to a base station, and transmit, to the base station, at least one UL transmission including the UL data and timing information associated with an arrival of the SDU at the PDCP layer. The base station may receive the at least one UL transmission including the UL data, identify timing information, and calculate an UL delay based at least in part on the timing information from the UE. The timing information may be communicated in at least one of a PDCP protocol data unit (PDU) header or a medium access control (MAC) control element (CE) (MAC-CE).

    Abstract: Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) may communicate in a wireless communications system. The base station may select a first bandwidth part from a plurality of bandwidth parts, the first bandwidth part having a bandwidth size corresponding to a traffic burst size for application data traffic within a time period. The UE may determine the bandwidth size using one or more parameters and indicate the bandwidth size to the base station. Additionally or alternatively, the base station may determine the bandwidth size using the one or more parameters. The base station may transmit, to the UE, a control signal indicating the first band-width part having the bandwidth size. The base station may schedule transmission of the application data traffic using the first bandwidth part and communicate the application data traffic with the UE using the first bandwidth part.
