Abstract: A user equipment (UE) transmits reference signals for positioning while in Idle or Inactive state. While in a connected state, the UE is pre-configured with Sounding Reference Signal (SRS) resource configuration including at least one of timing adjustment (TA) and an uplink (UL) transmission spatial filter. The UE transmits positioning SRS while in Idle or Inactive mode based on the pre-configuration. The TA and UL transmission spatial filter may be updated by a serving base station using control signals or a paging message received by the UE while in in Idle or Inactive mode. The validity of the TA and UL transmission spatial filter may be monitored using expiration timers or a relative position change threshold. The reference signals transmitted may be based on a UE may Physical Random Access Channel (PRACH), which is insensitive to TA changes. A long sequence PRACH may be used for improved positioning accuracy.

Abstract: The disclosure is directed to group communications in a mixed casting services wireless communication system. An embodiment detects a loss of multicast coverage at a user equipment (UE), notifies a server of the loss of multicast coverage, wherein the server is configured to provide a desired multicast communication, and requests that communications related to the desired multicast communication be conducted on a unicast service using application layer signaling independent of link layer signaling.

Abstract: In an embodiment, a first MBSFN area is configured to support a higher data rate than a lower data rate portion of a second MBSFN area, and an application server executes a common data rate mode by delivering a data stream for a group session to the first and second MBSFN areas via IP multicast at a common data rate that is regulated by quality feedback. In a further embodiment, the application server exits the common data rate mode and delivers the data stream to the first MBSFN area via IP multicast at an MBSFN-specific data rate that is higher than the common data rate, while delivering the data stream to the lower data rate portion of the second MBSFN area via IP unicast. In another further embodiment, the application server resumes the common data rate mode.

Abstract: In an embodiment, a network device obtains a plurality of data packets that are each associated with one of a plurality of different streams, wherein each of the plurality of obtained data packets includes a header portion with stream-specific routing information. The network device strips the stream-specific routing information from the plurality of obtained data packets to produce a plurality of stream-specific payload portions, which are merged into a shared payload portion of a stream-multiplexed data packet that includes common routing information for the plurality of streams in a common header portion. The network device transmits the stream-multiplexed packet to a target device, and the target device determines whether any of the plurality of different streams are relevant to the target UE based on stream-mapping information contained in the stream-multiplexed packet, and selectively decodes and processes the stream-specific payload portions corresponding based on the determination.
