Description

Resource allocation method and device The present application claims priority from the chinese patent office, application number 202311524529.9, application name "resource allocation method and apparatus" filed on day 14 11, 2023, the entire contents of which are incorporated herein by reference. Technical Field The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for resource allocation. Background Because of the respective drawbacks of both frequency division duplex FDD and time division duplex TDD, as an increase to FDD technology and TDD technology, studies are currently being conducted on Subband non-overlapping full duplex (Subband non-overlapping Full Duplex, SBFD) technology. Currently, 5G NR is generally performed based on a single frequency domain configuration of BWP when performing frequency domain resource allocation. However, the introduction of SBFD technology may cause that DL link and UL link of the terminal device have different available frequency domain resources in different time periods, and then only a single frequency domain configuration based on BWP cannot realize that BWP has different bandwidths in different time periods, that is, the current frequency domain resource allocation mode is not used any more. Therefore, it is desirable to provide a frequency domain resource allocation method adapted to SBFD technologies. Disclosure of Invention The embodiment of the application provides a resource allocation method and device, which are applied to the technical field of communication.

In this implementation, the resource location of the SBFD region is indicated by the first configuration information, and the resource distribution of the PUSCH or PDSCH on the SBFD region is indicated by the first scheduling information, so that a resource allocation manner adapted to the SBFD technology can be implemented. In one possible design, the first configuration information includes time domain location information and frequency domain location information of a first transmission direction. In one possible design, the SBFD region includes SBFD slots, the time-domain location information is used to indicate that at least one first slot is the SBFD slot, the first slot is at least a portion of a first type of slot indicated by a system information block, SIB, or a first radio resource control, RRC, configuration message, or The SBFD region includes SBFD symbols, and the time-domain location information is used to indicate that at least one first symbol is the SBFD symbol, where the first symbol is at least some of the first type of symbols indicated by the SIB or the first RRC configuration message.

In one possible design, the time domain location information includes a first bitmap, where bits with a first value in the first bitmap are used to indicate the first slot, or bits with a first value in the first bitmap are used to indicate the first symbol. In such an implementation, the time domain location indication of the SBFD region may be implemented by way of a bitmap, and discontinuous slot location configuration may be supported to enable flexible configuration of slots of the SBFD region. In one possible design, the time domain position information includes a time slot start position and a time slot number of the at least one first time slot, or The time domain position information includes a symbol start position and a symbol number of the at least one first symbol. In this implementation, the slot position indication for the SBFD region may be implemented by way of a start + number. In one possible design, the time domain location information includes a first resource indicator value RIV indicating a time slot start position and a time slot number of the at least one first time slot, or The first RVI is for indicating a symbol start position and a number of symbols of the at least one first symbol. In such an implementation, the time domain location indication of the SBFD region may be implemented by way of RIV to reduce signaling overhead. In one possible design, the time domain position information includes a first index value, a time slot in a time domain position corresponding to the first index val
