Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a beam failure recovery (BFR) message regarding a failed link, wherein the failed link is one of an indirect link with a network node via a relay node or a direct link with the network node, wherein the BFR message is transmitted on one of the indirect link or the direct link that is not the failed link. The UE may receive an updated beam configuration for the failed link on a selected beam indicated by the BFR message. Numerous other aspects are described.

Method, apparatus, and computer program product for a user equipment to receive a downlink control information message from an access point in a wireless communications network and to echo a new beam index in the PUCCH feedback resource in response to the message indicating a PUCCH feedback resource and containing a beam change information or in response to the message indicating a downlink grant containing a beam change indication MAC control element but so CSI-feedback is scheduled for the PUCCH feedback resource. If a scheduling request resource is indicated by the message or the MAC control element, the user equipment is triggered to transit a scheduling request on that indicated scheduling request resource. If a scheduling request resource is not indicated by the message or the MAC control element, the user equipment is triggered to perform a scheduling request procedure on a periodic scheduling request resource.

According to one aspect of the present disclosure, coverage can be improved by taking account of overhead.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit a first reference signal using a first network transmit beam corresponding to a first carrier.

Methods, systems, and devices for wireless communications are described. Techniques described herein provide for a network entity to determine a beam focusing distance for a reconfigurable intelligent surface (RIS) for a user equipment (UE) located in the near field region of the RIS. The beam focusing distance may be determined using reference signals for different test beam focusing distances within the near field region of the RIS. The test beams may have a same angular direction from the RIS to the UE. The test beams may have a beam focusing distance selected from a set of beam focusing distances within the near field region of the RIS.

A method for providing a self-reliant secondary network of communication nodes using resources associated with a primary network defining sector beams using corresponding resources including respective SSBs includes performing a beam search with respect to the sector beams, performing beam detection to detect neighboring beams among the sector beams, and performing geospatial beam selection to define a selected set of SSBs of respective ones of the sector beams as being geospatial white space unlikely to interfere with the primary network when utilized by the communication nodes in the secondary network. The method may further include performing power control with respect to the selected set of SSBs, and applying medium access control protocols to enable the secondary network to use the selected set of SSBs of the primary network.

An initial access method and an apparatus are provided. In the method, an RS set corresponding to an SSB is introduced. The SSB is sent by using a wideband and a wide beam, and an RS in the RS set occupies a small quantity of time domain resources through frequency division multiplexing and is sent by using a narrow beam. A transmit beam of the RS in the RS set is a refinement of a transmit beam of the SSB. Narrow beam training is completed by using the RS set, to find an optimal narrow beam pointing to a UE, so that in the method, time domain resource overheads of the SSB can be effectively reduced while communication efficiency is ensured.
