Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may provide, to a distributed unit (DU) of the base station, an indication of one or more candidate physical entity (PHY) profiles. The base station may receive, from the DU, an indication of a selected PHY profile, of the one or more candidate PHY profiles, to use for communication with a device, such as a user equipment. Numerous other aspects are described.

Abstract: The disclosure relates in some aspects to forbidden area procedures and connection release management for a user terminal (UT). Forbidden area-related procedures include, for example, using a special paging area code (PAC) in conjunction with a forbidden area, defining a location reporting threshold for a UT based on the proximity of the UT to a forbidden area, or using a default paging area code if a service restriction for a UT has ended. Connection release management includes, for example, a UT sending a request to cause the release of a Radio Connection that the UT no longer needs, or a UT sending a Location Indication (e.g., including a flag requesting release of a connection) to release the connection used for location reporting when a UT is done sending the location information and is going to go back to idle mode.

Abstract: Various aspects of the disclosure relate to managing ephemeris information. Provisions are made for providing ephemeris information to a user terminal (UT). Messages are defined for sending ephemeris information and for requesting ephemeris information. Ephemeris information for a subset of the satellites in a constellation may be sent to a UT to reduce signaling load. A UT may manage a database of ephemeris information to ensure freshness of the ephemeris information.

Abstract: Methods, systems, and devices for wireless communications are described. In an example, a method includes a first node receiving a precision time protocol (PTP) message, identifying one or more timing domains to be supported by the first node based at least in part on the PTP message, and sending, to a second node of the wireless communication network, an indicator of the one or more timing domains to be supported by the first node. Another example at a node includes receiving, from additional nodes of the wireless communication network, indicators of one or more timing domains supported by the additional nodes, receiving a PTP message associated with a timing domain, and sending the PTP message to a subset of the additional nodes based at least in a part on the indicators of one or more timing domains supported by the additional nodes.

Abstract: The present disclosure provide various methods, computer-readable media, and apparatuses for managing communication paths, which may include at least one direct communication path between UEs, such as a sidelink communication path. Illustratively, an apparatus of the present disclosure may be a UE or component thereof that is configured to establish a direct wireless communication link and an indirect wireless communication link with another UE to carry data associated with one traffic stream. Further, the apparatus may be configured to communicate with the other UE over at least one of the direct communication link or the indirect communication link after the direct communication link and the indirect communication link are established with the other UE.

Abstract: Apparatus, methods, and computer program products for relaying and side link communication are provided. An example method may include receiving, from a BS via a controlled discovery procedure, a query to verify a sidelink procedure with at least one UE. The example method may further include establishing, via the BS as a L2 relay, the sidelink procedure with the at least one UE. The example method may further include switching from the sidelink procedure to a sidelink PDCP procedure with a hybrid mode, the BS being an L2 relay for the sidelink PDCP procedure. The example method may further include transmitting to the at least one UE via the BS as the L2 relay, or receiving, from the at least one UE via the BS as an L2 relay, one or more PDCP PDUs corresponding to L2.

Abstract: Certain aspects of the disclosure provide techniques for signaling port information of user equipment (UE) ports in a wireless communication system including a radio access network. Certain aspects provide a method for wireless communication. The method includes receiving, at a network node, port information of one or more ports of one or more UEs. The method further includes deriving a network topology indicating connectivity between devices comprising the one or more UEs based on the port information of the one or more ports.

Abstract: The disclosure relates in some aspects to enabling a user terminal (UT) to obtain information about nearby cells and any beams generated by nearby cells. For example, a network can send a neighbor cell list to UTs, where the list identifies the cells in that neighborhood and provides information about any beams generated by those cells. Thus, a UT can learn the neighboring beams/cells that the UT can reselect to if the current beam/cell becomes weak. In some aspects, the UE can learn the attitude (e.g., pitch, roll, yaw, or any combination thereof) profile of neighboring satellites as well as the pointing angles and the ON-OFF schedules of their beams. In some aspects, the UT can learn a start angle and a span for a satellite and use this information to identify a satellite the UT can reselect to if the current beam/cell becomes weak.

Abstract: Methods and systems are described for verifying the source and integrity of a media presentation description (MPD) defined by the Dynamic Adaptive Streaming over HTTP (DASH) protocol. A streaming client receives an MPD from an MPD publisher. The MPD can include addresses associated with one or more media servers and/or advertising servers. The streaming client can receive from the MPD publisher at least one of a digital signature, cryptographic key, and certificate information associated with the MPD. The streaming client can verify the legitimacy of the MPD by verifying the digital signature using the received cryptographic key. The streaming client may use the certificate information to verify the MPD. The streaming client can prevent playing the media associated with the MPD if the MPD is not legitimate. The legitimacy of servers associated with addresses in the MPD may also be verified using authentication information for servers stored in the MPD.

Abstract translation: 描述了用于验证由动态自适应流HTTP（DASH）协议定义的媒体呈现描述（MPD）的源和完整性的方法和系统。 流媒体客户端从MPD发布者接收MPD。 MPD可以包括与一个或多个媒体服务器和/或广告服务器相关联的地址。 流媒体客户端可以从MPD发布者接收与MPD相关联的数字签名，加密密钥和证书信息中的至少一个。 流客户端可以通过使用接收的加密密钥验证数字签名来验证MPD的合法性。 流媒体客户端可以使用证书信息来验证MPD。 如果MPD不合法，流媒体客户端可以阻止播放与MPD相关联的媒体。 与MPD中的地址相关联的服务器的合法性也可以使用存储在MPD中的服务器的认证信息进行验证。
