Abstract: A tethering user equipment (UE) device, such as a cell phone, may be tethered to a tethered device, such as augmented reality (AR) glasses. The tethered device may execute a Web Real-time Communication Protocol (WebRTC) endpoint application, and the tethering UE device may execute a WebRTC endpoint support function. The tethering UE device may access WebRTC signaling functions of a WebRTC operator network on behalf of the tethered device to send and receive AR media data of a WebRTC communication session. The tethered device may present received AR media data (e.g., audio, video, and image data) and may collect and send user movement data (e.g., view orientation, physical movement data, controller interaction data, or the like) to the tethering UE device to cause the tethering UE device to send the user movement data to other devices participating in the WebRTC communication session.

Abstract: A method for wireless communication includes validating a PUR configuration in a NTN based on location-related information associated with a satellite. For example, a UE may determine, based on location-related information of a satellite in a non-terrestrial network, whether a preconfigured uplink resource (PUR) configuration is valid. The UE may also transmit, to a base station (BS) via the satellite in response to determining that the PUR configuration is valid, a communication signal in a PUR. For example, the UE may determine, based on the location-related information associated with the satellite, if the parameter satisfies the threshold, and transmit UL data in a PUR occasion based on the determined parameter satisfying the threshold.

Abstract: Systems, methods and instrumentalities are disclosed for decoding data. For example, it may be determined, in a current slot, whether data received in a previous slot is decoded successfully. The data received in the previous slot may be included in a Physical Downlink Shared Channel (PDSCH). If the data received in the previous slot is not decoded successfully, preemptive multiplexing information may be detected in a first search space. The data received in the previous slot may be decoded, for example, using detected preemptive multiplexing information. The preemptive multiplexing information may be of a current slot. The preemptive multiplexing information may be comprised in a first DCI. A second search space of the current slot may be searched. For example, the second search space may be searched for a second DCI. The first DCI and the second DCI may be different.

Abstract: A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).

Abstract: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may identify at least one scheduling offset associated with a propagation delay between a base station of a NTN and the UE. The apparatus may also select a first scheduling offset of the at least one scheduling offset associated with the propagation delay between the base station and the UE. Additionally, the apparatus may transmit, to the base station, an uplink transmission based on the first scheduling offset, the uplink transmission being associated with a PUSCH, a PUCCH, or a PRACH.

Abstract: An example method includes sending or receiving a session description protocol (SDP) message that includes binding information that associates a first RTP header extension and a second RTP header extension for an RTP session, wherein the binding information is indicative of a first timestamp in the first RTP header extension, and the first timestamp in the second RTP header extension, both being indicative of a time at which a first RTP packet including the first RTP header extension is transmitted. The method includes transmitting, by a first device, the first RTP packet and receiving, by the first device, a second RTP packet, the second RTP packet including the second RTP header extension including the first timestamp, a second timestamp, and a third timestamp. The method includes determining, based on at least one of the first timestamp, the second timestamp, or the third timestamp, a delay.

Abstract: Methods, systems, and devices for wireless communications are described. A reference signal distribution scheme described herein may allow for the benefits of orthogonal cover codes, and improve mechanisms to identify and address resulting carrier frequency offset. Techniques are described for distributing reference signals (e.g., demodulation reference signals) over a set of resources. The reference signals may be arranged in equi-spaced clusters, where groups of the reference signals per cluster are spaced according to a first timing offset, and where each cluster may be spaced according to a second timing offset. The network may configure the reference signal distribution scheme at various user equipments, indicating values for the timing offset. The user equipments may transmit reference signals according to the indicated scheme.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may account for the application of orthogonal cover coding (OCC) to an uplink transmission when determining the transport block size (TBS) for the uplink transmission. OCC may be used to multiplex transmissions from multiple UEs and may involve spreading information. Described techniques may involve accounting for the spreading of information bits when determining the TBS for the uplink transmission to which OCC is applied. Sub-physical resource block (sub-PRB) frequency allocations may be provided for uplink transmissions. The UE may account for the allocated quantity of sub-carriers when determining the quantity of information bits. To indicate a sub-PRB, the UE may be configured to reinterpret one or more fields of an existing downlink control information (DCI) format as indicating the allocated sub-carriers, or a new DCI format may be configured that includes fields for indicating a sub-PRB allocation.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

The first wireless device may transmit an indication of one or more candidate APs for a handover of the second wireless device from the first wireless device to maintain the connectivity between the second wireless device and a network. As such, the second wireless device may use the wireless characteristics to determine whether to handover to a candidate AP or maintain the tethered wireless connection with the first wireless device.

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.
