Embodiment approach

[0352] Specifically, the first implementation of determining the correspondence between CORESET groups and beam failure recovery parameters includes that each CORESET group corresponds to a set of beam failure recovery parameters, and each CORESET group corresponds to a beam failure recovery process. , perform one or more of the following operations: beam failure detection, beam failure request, new beam information reporting indication (that is, new reference signal reporting), when beam failure requests in two CORESET groups collide, or two The new beam information report of the CORESET group indicates a collision. The two request information or report information can be combined and reported, or only one of them is reported, or the beam failure request of one CORESET group collides with the new beam information report of another CORESET group. It is also possible that the two requested information or reported information can be reported together, or only one of them can be r...

Abstract

The invention provides an information determination method and device, a corresponding relation determination method and device, equipment and a medium. The information determination method comprisesthe following steps: determining second information according to first information, wherein the first information comprises at least one of the following information: a time domain parameter of a search space, a CORESET group, a CORESET set, the number of CORESETs, the number of frequency domain bandwidths, a frequency domain bandwidth group, a PUCCH resource group, a first type beam failure recovery parameter, signaling information and a predetermined rule; and the second information comprises at least one of the following parameters: a second type of beam failure recovery parameter, a wireless link reference signal, a frequency domain bandwidth corresponding to MAC-CE signaling, a PUCCH resource corresponding to the MAC-CE signaling, and a quasi co-location parameter of a downlink channel or a signal.

Description

technical field [0001] The present application relates to the field of wireless communication, and specifically relates to a method, device, equipment and medium for determining information and determining a corresponding relationship. Background technique [0002] In the 5G millimeter wave system, due to the severe channel fluctuation, beam misalignment between the base station and the user may occur. Beam fault recovery can help base stations or users adjust the current faulty beam to an available beam according to beam measurement results, thereby avoiding frequent wireless link failures caused by beam misalignment. In NR (New Radio, new air interface), the beam failure recovery process is defined, but only the case where the number of CORESET (Control Resource Set, control resource set) is relatively small is considered. When the number of CORESET or the frequency domain bandwidth to be detected In many cases, how to quickly recover from beam failure and improve link ro...
