Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit, to a user equipment (UE) operating in a discontinuous reception mode, a wakeup signal indicating whether data is available to be transmitted to the UE, the wakeup signal transmitted using a first set of transmit beams, which may be selected from a periodic beam management procedure, in accordance with a beam sweeping configuration. The base station may receive, from the UE and based at least in part on the wakeup signal, a response signal. The base station may perform, based at least in part on the response signal, further beam update procedures to identify a second set of transmit beams for future transmissions of the wakeup signal and/or for transmission of physical downlink control channel (PDCCH) to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for transmitting, from a user equipment (UE) to a base station, a report indicating a beamforming capability of the UE, receiving, from a base station, a configuration for a plurality of control resource sets (CORESETs) based at least in part on the report, selecting multiple CORESETs of the plurality of CORESETs, and monitoring the selected multiple CORESETs during a monitoring occasion. In some examples, the UE may also monitor one or more unselected CORESETs that have a quasi co-location relationship with one of the selected CORESETs.

Abstract: A wireless node (e.g., a slave relay node) may receive scheduling commands over multiple wireless links and identify a scheduling conflict. For example, the wireless node my identify a conflict of wireless resources indicated by the received scheduling commands. The wireless node may select a non-conflicting subset of the scheduling commands based on a conflict policy, and transmit data over the wireless links according to the non-conflicting subset of the scheduling commands. Additionally or alternatively, the wireless node may transmit a conflict report indicating the identified scheduling conflict. The conflict report may be sent to other wireless nodes (e.g., master relay nodes associated with the conflicting scheduling commands). The other wireless nodes may engage in negotiation signaling to resolve the scheduling conflict, and may transmit an updated scheduling command to the slave relay node. The slave relay node may transmit data over wireless links based on the updated scheduling command.

Abstract: A UE may identify a first indication associated with a first signaling to be received in a time interval and identify a second indication associated with a second signaling to be received in the time interval. The UE may select to receive and receive, in the time interval, at least one of the first signaling or the second signaling based on at least one of the first or second indications. One or more of the first and second indications may be received from a BS or determined by the UE via predefined or other means. A BS may convey indications of the first and/or second signaling. The first and second indications may be transmitted sufficiently before the signaling in an effort to allow the UE to select and tune its receiver beam in the direction of the signaling to be received.

Abstract: Certain aspects of the disclosure provide techniques for a user equipment (UE) to determine a receive beam of a plurality of receive beams for receiving an upcoming transmission from a base station, wherein the determining is based on whether an indication is received from the base station indicating if the upcoming transmission includes a reference signal (RS) multiplexed with additional data. The techniques further provide for the UE to receive the upcoming transmission using the determined receive beam.

Abstract: Methods, systems, and devices for wireless communications are described. A relay device may detect an upstream radio link failure (RLF) associated with an upstream link of a wireless backhaul, where the wireless backhaul includes a first wireless link between the relay device and a first upstream backhaul device. The relay device may provide a first indication of the upstream radio link failure over a second wireless link between the relay device and a first downstream device. The relay device may establish a third wireless link with a second upstream backhaul device based on the detected upstream radio link failure. The relay device may provide multiple-access services to one or more downstream devices, where providing the multiple-access services is based on backhaul communications between the relay device and the second upstream backhaul device over the third wireless link.

Abstract: Methods, systems, and devices for wireless communications are described that provide for selection of different sets of transmission beams by a user equipment (UE) for establishing beamformed communications with a base station. Each transmission beam of a first set of transmission beams may have corresponding uplink random access channel (RACH) resources. A UE may monitor for transmission beams from a base station and select a first transmission beam of the first set for communications with the base station. As part of a connection establishment, the base station may provide configuration information that indicates a second set of transmission beams that includes each transmission beam of the first set of transmission beams and at least an additional transmission beam. In some cases, the additional transmission beam may be mapped to a first RACH resource that also corresponds to a first transmission beam of the first set of transmission beams.

Abstract: Methods, systems, and devices for wireless communications are described that provide for multiple timing advance offsets that may be used in communications between wireless devices on a wireless communications system. A first timing advance offset may be a fixed offset that has a predetermined value or is selected from a set of available predetermined values, and a second timing advance offset may be adjustable by a wireless device. The second timing advance offset may be used in cases where relatively large distances between wireless devices are present in a system, where certain fixed timing advances are used in addition to or irrespective of a receiving devices propagation delay, where one or more parent nodes have an associated timing reference, or combinations thereof.

Abstract: Aspects described herein relate to communicating timing advance (TA) values in an integrated access and backhaul (IAB) network. A first node in a wireless network can receive a media access control (MAC) control element (CE) indicating a downlink transmission timing advance for transmitting downlink communications. The first node can transmit downlink communications based on the MAC CE.
