摘要： 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.

摘要： 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.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit configuration information associated with identifying a plurality of sets of random access channel (RACH) occasions (ROs), wherein a first set of ROs, of the plurality of sets of ROs, is associated with a first set of parameters for a low-resolution analog to digital converter (ADC) and a first mode of the network node, and a second set of ROs, of the plurality of sets of ROs, is associated with a second set of parameters for a high-resolution ADC and a second mode of the network node. The network node may communicate, when operating in a particular mode of the network node, using a particular set of ROs, of the plurality of sets of ROs, associated with the particular mode of the network node. Numerous other aspects are described.

摘要： 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.

摘要： In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for establishing, by a user equipment (UE), a first time period to evaluate one or more quality parameters of one or more reference signals, wherein the first time period is based on at least one of a number of panels of the UE or a number of beams that the UE monitors simultaneously; determining, by the UE, a quality parameter of a beam or a cell based on the one or more quality parameters of the one or more reference signals; and determining, by the UE, whether the one or more quality parameters of the one or more reference signals exceeds a quality threshold.

摘要： Methods, systems, and devices for wireless communication are described. Methods, systems, and devices provide for different tone spacing schemes for different channels. Methods, systems, and devices also provide for different tone spacing schemes for different stages of communication between a UE and a base station. The base station may indicate, to the UE, the tone spacing scheme in a control channel, a synchronization signal, or a reference signal and the tone spacing scheme may be selected by the base station from available tone spacing schemes for communication. Tone spacing schemes may also be referred to as numerologies.
