Abstract: Techniques and apparatuses are described for enabling a base station to enable peer-to-peer communication among multiple user equipment (UE) over a mmWave link. The techniques described herein overcome challenges that the multiple UEs might otherwise face in trying to establish peer-to-peer links on their own. By relying on the base station to grant air interface resources for the UE to perform peer-to-peer communications with the UE, the UE can communicate directly with the other UE, independent of links that the UE or the other UE maintains with the base station. Furthermore, reliance on the base station may help the UE and the other UE mitigate interference from other nearby mmWave links that are separate from the peer-to-peer wave link. In addition, by relying on the base station to specify the beam sweeping pattern, beam acquisition by the UE and the other UE may be improved.

Abstract: Methods, devices, systems, and means for intra-UECS communication by a coordinating user equipment, UE, in a user equipment-coordination set, UECS, are described herein. The coordinating UE allocates first air interface resources to a second UE and second air interface resources to a third UE for intra-UECS communication. The coordinating UE receives, using the allocated first air interface resources, an Internet Protocol, IP, data packet from the second UE in the UECS. The coordinating UE determines that a destination address included in the IP data packet is an address of the third UE and transmits, using the allocated second air interface resources, the IP data packet to the third UE.

Abstract: This document describes techniques and devices for determining a machine-learning architecture for network slicing. A user equipment (UE) and a network-slice manager communicate with each other to determine a machine-learning (ML) architecture, which the UE then employs to wirelessly communicate data for an application. In particular, the UE selects a machine-learning architecture that provides a quality-of-service level requested by an application. The network-slice manager accepts or rejects the request based on one or more available end-to-end machine-learning architectures associated with a network slice that supports the quality-of-service level requested by the application. By working together, the UE and the network-slice manager can determine an appropriate machine-learning architecture that satisfies a quality-of-service level associated with the application and forms a portion of an end-to-end machine-learning architecture that meets the quality-of-service requested by the application.

Abstract: Techniques and apparatuses are described that implement cooperative bistatic radar sensing using deep neural networks. In particular, a base station (120) operates as a transmitter of the bistatic radar, and the user equipment (110) operates as a receiver of the bistatic radar. During radar sensing, the base station (120) and the user equipment (110) use their respective deep neural networks (460 and 420) for signal generation and signal processing. The deep neural networks (460 and 420) also enable the base station (120) and the user equipment (110) to utilize the same hardware for both radar sensing and wireless communication. With cooperative bistatic radar sensing, the base station (120) and the user equipment (110) can compile explicit information about objects within an operating environment and use this information to improve wireless communication performance.

Abstract: Techniques and apparatuses are described that implement control signaling for monostatic radar sensing. In particular, a base station uses control signaling to configure a user equipment for monostatic radar sensing and control when monostatic radar sensing is performed by the user equipment. With control signaling, the base station can enable monostatic radar sensing to occur using similar frequency resources used for wireless communication, which enables efficient use of a frequency spectrum. The base station can also use control signaling to reduce interference observed by other user equipment as the user equipment performs monostatic radar sensing. By performing monostatic radar sensing, the user equipment compiles explicit information about objects within an operating environment and shares this information with the base station. The base station uses this information to improve wireless communication performance.

The base station determines that the first joint transmission fails to meet a performance metric and directs the multiple UEs participating in the UECS to add signal adjustments to a second joint transmission.

Abstract: Techniques and apparatuses are described for deep neural network (DNN) processing for a user equipment-coordination set (UECS). A network entity selects (910) an end-to-end (E2E) machine-learning (ML) configuration that forms an E2E DNN for processing UECS communications.

The network entity receives (940) feedback associated with the UECS communications and identifies (945) an adjustment to the E2E ML configuration. The network entity then directs at least some of the multiple devices participating in an UECS to update the respective sub-DNN of the E2E DNN based on the adjustment.

The UE controls, based on the one or more satellite parameters, operation of a software application that utilizes a data service provided via the at least one satellite.

Abstract: This document describes techniques and apparatuses for distributed network cellular identity management. In particular, a distributed-network cellular-identity-management (DNCIM) server includes a lookup table that stores and relates together a user-equipment (UE) public key associated with a UE private key, a core-network (CN) public key associated with a CN private key, and a subscriber identity. Using the DNCIM server, the UE and an authentication server respectively generate two different (e.g., asymmetric) cipher keys based on the UE private key and the CN public key, and the UE public key and the CN private key. The UE and the authentication server can also authenticate one another by referencing information in the lookup table of the DNCIM server. Using these cipher keys, the UE and the authentication server can establish secure communications with each other.

Abstract: This document describes techniques and systems that enable a base-station-initiated grant revoke. The techniques and systems allow a base station to generate and send a grant-revocation message (GRM) to a user equipment (UE) to revoke a scheduled uplink (UL) or downlink (DL) grant from the base station. The base station can transmit the GRM to the UE using a variety of techniques. For example, based on a trigger event, the base station may assign a UE identifier, such as a specific radio network temporary identifier (RNTI), to the UE and transmit the GRM to the UE using a revoke-physical-downlink-control-channel (R PDCCH) transmission that is associated with the UE identifier. These techniques allow the base station to revoke a scheduled UL or DL grant, which can enable the UE to quickly address timing-critical resource allocation issues and mitigate the effects of adverse operating conditions.

The base station and the other base stations in the ACS jointly-transmit the joint-codebook to the UE and receive Precoding Matrix Indicator, PMI, feedback from the UE. The base station and the other base stations in the ACS jointly-process downlink data for the UE using the PMI feedback and the joint-codebook and jointly-transmit the downlink data to the UE.
