Abstract: Certain aspects of the present disclosure provide techniques for enhancing ephemeris for non-terrestrial networks. For example, UEs of different orbit propagation capabilities (e.g., computing orbit propagation models of different accuracy levels) may receive additional ephemeris parameters. In one aspect, a network entity may determine at least one additional set of ephemeris parameters that includes different ephemeris parameters than one or more basic sets of ephemeris parameters associated with a satellite that provides a coverage for the network entity. The network entity may transmit broadcast signaling indicating the at least one additional set of ephemeris parameters. The UE may receive and use the at least one additional set of ephemeris parameters in an orbit propagation model to compute a state of motion of the satellite.

Abstract: A first client device may participate in a media communication session with a second client device. The first client device may receive a local IP address type of the second client device. The first client device may provide the local IP address type to an intermediate network device. In this manner, the intermediate network device may use the local IP address type to calculate a protocol data unit (PDU) set size (PSSize) based on the local IP address type. The intermediate network device may add the calculated PSSize value to a tunnel header of a tunnel packet that encapsulates a packet including media data sent by the second client device to the first client device. In this manner, other network devices may receive accurate values for the PSSize when media data is exchanged via network tunnels, to ensure that all packets of a common PDU set are delivered together.

Abstract: An example device includes one or more memories configured to store a current real-time transport protocol (RTP) packet and one or more processors. The one or more processors are configured to determine a protocol data unit (PDU) set, the PDU set comprising a plurality of PDUs, each PDU comprising a corresponding RTP packet. The one or more processors are configured to determine, for a current RTP packet of the PDU set, a remaining PDU set size, the remaining PDU set size being indicative of a size of the sum of a remainder of the PDUs of the PDU set. The one or more processors are configured to transmit the current RTP packet including an RTP header extension comprising a value indicative of the remaining PDU set size.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a first cell. The UE may receive a request to report one or more parameters associated with handover from the first cell to a second cell during a time period. The one or more parameters may include an estimated propagation delay between the UE and the second cell during the time period, an estimated rate of change in propagation delay during the time period, or both. The UE may transmit a message indicating the parameters in response to the request. The UE may receive an indication of an uplink grant occasion associated with the handover during the time period based on indicating the parameters.

Abstract: Aspects of the present disclosure provide systems and methods for informing a user equipment (UE) that which beam the UE is being served, for example, such as in relation to bandwidth part (BWP) switching in a non-terrestrial network (NTN). According to certain aspects, a network entity may transmit to a user equipment (UE) signaling indicating at least one BWP switch. The network entity provides, to the UE, an indication of a serving synchronization signal block (SSB) for the UE to use after the BWP switch.

Abstract: A UE may receive, from at least one cell via at least one bit in a MIB or a SIB, a barring indication based on a supported network of the at least one cell and a supported network of the UE. The supported network of the at least one cell may correspond to a TN or an NTN, and the supported network of the UE may correspond to a TN or an NTN. The UE may skip, based on the received barring indication, a selection of the at least one cell for communication. Accordingly, the UE may not camp on the at least one cell. The barring indication for NTN-supporting UEs and for TN-supporting UEs may be separately indicated via the MIB or the SIB.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a media server may set up a communication session to support an extended reality (XR) application. The UE may receive an indication of a semantic model to use for processing data packets to be received at the UE. The semantic model is determinative of incomplete audio data based on a meaning of known audio data. The UE may receive a set of data packets that encodes a first portion of a sequence of audio data and generate, using the semantic model and one or more data packets of the set of data packets, a second portion of the sequence of audio data. The second portion is in addition to the first portion.

Abstract: Aspects relate to mechanisms for wireless communication devices to update satellite and beam specific information. A user equipment (UE) selects a first cell associated with a first satellite for wireless communication in the non-terrestrial network. The UE determines whether to use one or more standard parameters or one or more satellite-cell specific parameters for accessing the first cell. The one or more standard parameters are based on one or more standard characteristics common to a plurality of satellites including the first satellite. The one or more satellite-cell specific parameters are based on a change to at least one standard characteristic of the one or more standard characteristics of the first satellite.
