Abstract

The invention discloses a method for determining random access resources and terminal equipment, which can solve the problem of possible resource collision between RMSI and the random access resources. The method comprises the following steps that the terminal equipment determines a resource overlapped with a target time domain symbol in a random access resource group as an unavailable resource, wherein the target time domain symbol comprises at least one symbol, the symbol is a symbol occupied by target residual minimum system information RMSI, the target RMSI comprises at least one RMSI associated with a target synchronization signal block SSB, the target SSB comprises an actually transmitted SSB and an SSB having a quasi co-location relationship with the actually transmitted SSB, and the unavailable resources are not used for random access.

Description

technical field [0001] The embodiment of the present application relates to the field of communication technologies, and specifically relates to a method and a terminal device for determining random access resources. Background technique [0002] In the 5G new radio (New Radio, NR) system, the base station will configure a set of random access resources for the terminal, and this set of random access resources appears periodically. Further, the protocol specifies a series of rules for determining which random access resources are valid and which are invalid in the above group of random access resources. [0003] In the unlicensed frequency band, when the terminal determines the effective random access resources based on the given random access resources, compared with the 5G NR system, it may encounter the problem of lacking static or semi-static uplink and downlink indications. [0004] Since the NR-Unlicensed (NR-U) system occupies the channel based on the Listen Before T...
