Abstract: A method for allocating available transceiver resources across different component carriers (CC) includes obtaining a carrier aggregation capability that includes a list of available CCs supported by the UE at a current location for simultaneous communication with a carrier aggregation capable network. The method also includes, for each of the available CCs, obtaining an expected key performance indicator (KPI) associated with the corresponding available CC at the current location. The method also includes allocating the available transceiver resources across the available CCs based on the expected KPIs at the current location.

Abstract: This document describes monitoring and managing wireless backhaul integrated with mobile access in fifth generation new radio (5G NR) wireless networks. The techniques described employ an Integrated Backhaul-Access and Mobility Function (IB-AMF) to enable authorization of a base station to access a 5G network through another base station. The techniques described also monitor channel conditions and traffic loads to manage backhaul links and facilitate handovers of base station backhaul connections between other base stations.

Abstract: Techniques and apparatuses are described for enabling dual connectivity with secondary cell-user equipment. In some aspects, a base station (121) serving as a primary cell forms a base station-user equipment dual connectivity (BUDC) group (410) by configuring a user equipment (UE, 111) as a secondary cell-user equipment (SC-UE, 420) to provide a secondary cell. The base station (121) or SC-UE (420) can then add other UEs (112, 113, 114) to the BUDC group (410) thereby enabling dual connectivity for the UEs through the primary cell or secondary cell provided by the SC-UE (420). In some cases, the SC-UE (420) schedules resources of an air interface (302) by which the other UEs to communicate with the SC-UE (420). By so doing, the SC-UE (420) can communicate data with the other UEs (112, 113, 114) of the BUDC group (410) without communicating through a base station (121, 122), which decreases latency of communications between the UEs (111-114) of the BUDC group (410).

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: This document describes techniques and apparatuses for user-equipment coordination set (UECS) beam sweeping. In aspects, a user equipment (UE) receives an indication to coordinate beam sweeping with a UECS. The UE directs each UE in the UECS to perform a beam-training procedure by receiving a set of downlink beam transmissions, and forwards beam report information to a base station. In implementations, the UE receives an indication of one or more beam identities and one or more assigned time slots, and directs at least two UEs in the UECS to use specific beams indicated by the beam identities at specific time slots indicated by the assigned time slots, such as by transmitting a respective beam identity and a respective time slot to each UE of the at least two UEs.

Abstract: This document describes techniques and apparatuses for joint-transmission over an unlicensed frequency band using a user equipment (UE)-coordination set. In aspects, a first UE in a UE-coordination set acts as a coordinating UE. The coordinating UE receives, using a local wireless network connection, uplink data from a second UE in the UE-coordination set. The coordinating UE distributes, using the local wireless network connection, the uplink data to at least a third UE in the UE-coordination set. The coordinating UE receives, from at least one UE in the UE-coordination set, respective results of a clear channel assessment of the unlicensed frequency band. The coordinating UE determines a specified time to begin joint-transmission of the uplink data based on the results and coordinates the joint-transmission by directing the at least one UE to initiate the joint-transmission of the uplink data based on the specified time.

Abstract: The present disclosure describes methods and apparatuses for forming beams that carry data transmitted from a user device to a base station. In some aspects, a transmission configuration is determined based on a set of beams downlinking the base station to the user device and carrying a set of data. The determined transmission configuration is the applied to a transceiver of the user device, which then transmits another set of data carried by another set beams uplinking the user device to the base station.

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 methods, devices, systems, and means for user-equipment-coordination-set (404) control aggregation that facilitates more efficient control-plane signaling in comparison to conventional wireless communication systems. Overhead for control-plane signaling is reduced by communicating reports and control commands for the multiple user equipments (110) in the user-equipment-coordination-set (404) in a single message instead of communicating a single control message for each user equipment (110). Additionally, the user-equipment-coordination-set (404) uses joint-reception and joint-transmission, to increase the reliability of communicating reports and control commands, especially in the case of challenging radio communication conditions between a base station (121) and an individual UE (110) located near the edge of a cell provided by the vase station.

Abstract: Techniques and apparatuses are described for enabling base stations (121, 122) to coordinate for canceling cross-link interference (380). The techniques and apparatuses described herein overcome challenges that a single base station (121) might otherwise face in trying to compensate a reception (131) by the base station (121) for cross-link interference (382) from a transmission (132) by another base station (122). The techniques and apparatuses described herein enable the base stations (121, 122) to form coordination sets to exchange information to enable the base stations (121, 122) to accurately reconstruct cross-link interference (380) and ultimately cancel the cross-link interference (380) to improve link quality.
