Abstract: A first apparatus may communicate with a user equipment (UE) through an active beam. The first apparatus may transmit, to the UE, information indicating a periodicity at which control information is to be communicated on a control channel through a control-information beam. The first apparatus may communicate, with the UE, the control information on the control channel through the control-information beam at the periodicity. Further, the first apparatus may receive a request to change the active beam, which may indicate a beam index corresponding to a second beam, and the first apparatus may change the active beam to the second beam corresponding to the beam index indicated by the request.

Abstract: This disclosure provides systems, methods and apparatuses for efficient signaling of feedback regarding communications of a relaying operation. In some aspects, a relay node may defer feedback regarding reception of a first communication until relaying feedback regarding the payload of the first communication, thereby reducing overhead and signaling burden. In some aspects, a relay node may skip the transmission of feedback regarding the first communication altogether, either on the assumption that the link between the relay node and the first wireless node is reliable, or on the basis of the first wireless node being able to infer the reception of the first communication based on subsequent communications. In some aspects, a relay node may be enabled to skip forwarding of feedback from a second wireless node, such that the first wireless node can infer that the payload was received if no negative feedback associated with the payload is received.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may concurrently configure repeaters in a wireless communications system via multicast control messaging. The base station may identify a quantity of repeaters in communication with the base station. Some repeaters may be in communication with the base station via other repeaters, for example in a chain configuration. The base station may prepare a multicast message including control information for the quantity of repeaters. In some examples, the base station may transmit the multicast message directly to each repeater in the quantity of repeaters, which may be referred to as a single hop control transmission. In some examples, the base station may transmit the multicast message via one or more chains of repeaters, which may be referred to as a multi-hop control transmission. The described techniques may include improved repeater operations and promote efficient repeater communications, among other benefits.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus may be a repeater node. The apparatus may receive, at one or more first antennas of the node, a first signal via at least one first beam. The apparatus may measure, at one or more third antennas of the node, at least one of a power or a quality of at least one third beam. The at least one of the power or the quality of the at least one third beam may be measured at a same time as the first signal is received. The apparatus may forward, at one or more second antennas of the node, the first signal via at least one second beam.

Abstract: The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a communication system may include a repeater that relays communications between communication devices. The repeater determines a downlink gain value to use for one or more downlink initial access messages received at the repeater. The repeater determines an uplink gain value to use for one or more downlink initial access messages received at the repeater. The uplink gain value is based on the downlink gain value and a noise level related to a channel between the communication device and the repeater. The repeater receives a downlink initial access message, and applies the downlink gain value to the downlink initial access message. The repeater receives an uplink initial access message, and applies the uplink gain value to the uplink initial access message.

Abstract: In order to maintain conformance with exposure limits, in band measurements may be performed. A method, a computer-readable medium, and an apparatus may be provided for wireless communication at a user equipment. The apparatus receives an indication of a cell specific resource, e.g., a cell specific resource available for MPE measurement. The apparatus then performs a measurement based on the cell specific resource and determines whether to adjust a transmission characteristic of the user equipment based on whether the measurement meets a threshold. In another aspect a base station apparatus may configure a cell specific resource in which a user equipment may perform an MPE measurement and control use of the cell specific resource for the MPE measurement.

Abstract: Wireless communications systems and methods related to mitigating maximum permissible exposure (MPE) constraints based on user equipment (UE) feedback are provided. A first wireless communication device transmits, to a second wireless communication device, a plurality of reports, each report indicating an allowable transmission power level at the first wireless communication device satisfying an MPE parameter. The first wireless communication device receives, from the second wireless communication device, a first configuration based on an MPE profile associated with the first wireless communication device in response to the plurality of reports. The first wireless communication device transmits, to the second wireless communication device, a first communication signal over a first beam based on the first configuration.

Abstract: All or a portion of a timeslot of a slotted communication system may be dynamically designated for transmitting or for receiving. For example, a timeslot originally designated for receiving information at a wireless node may be temporarily designated for transmitting information from the wireless node. Such a designation may be made to accommodate a temporary asymmetry in traffic flow between wireless nodes or may be made based on other criteria. In some aspects, a resource utilization messaging scheme may be employed to mitigate interference associated with the designation of timeslots for transmitting or receiving.
