In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description is given of related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as an alternative, which all belong to the protection scope of the embodiments of the present application.
Currently, a terminal can support only one active BWP within one carrier and only a continuous BWP configuration, i.e., frequency domain resources configuring BWP are continuous. The configuration of the frequency domain resource locations of the physical channel and the physical signal are both configured or indicated with reference to the continuous frequency domain resource of the BWP where they are located, and as an example, the physical channel is: physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), physical downlink control channel (Physical Downlink Control Channel, PDCCH), physical uplink control channel (Physical Uplink Control Channel, PUCCH), physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), and the like, and examples of the physical signals include: channel state information Reference signals (Channel State Information-Reference signals, CSI-RS), sounding Reference signals (Sounding Reference Signal, SRS), and the like.
Currently, there are many discontinuous smaller bandwidth spectrums for NR, as shown in fig. 2, if the terminal can only aggregate the carriers according to the previous spectrum usage, but one Transport Block (TB) can still transmit in one carrier. Since the bandwidth of each carrier is small, a large TB size (TB size) cannot be supported. For one service packet, the base station can only split it into multiple small TBs for transmission, which requires multiple PDCCHs to schedule multiple small TBs respectively. On the other hand, since the bandwidth of each carrier is small, the PDCCH of a larger aggregation level cannot be supported.
In addition, in the flexible duplex scenario, as shown in fig. 3, an Uplink (UL) frequency domain resource may be added in the middle of a Downlink (DL) frequency domain resource of a time division duplex (TDD band), so as to improve uplink throughput of the TDD band and reduce uplink delay.
If the terminal can only support BWP of continuous frequency domain resources according to the current design manner, more than two BWP must be configured for the terminal, but the terminal can only operate on one BWP at a time, which also results in insufficient use of frequency domain resources by the terminal and reduced throughput.
For this reason, the following technical solutions of the embodiments of the present application are proposed. The technical solution of the embodiment of the present application provides a frequency domain resource allocation method, which implements allocation of a frequency domain resource discontinuous in the frequency domain (i.e. BWP of the discontinuous resource). As an application scenario, for a full duplex scenario, a terminal is configured with a discontinuous downlink BWP. As another application scenario, for a small spectrum aggregation scenario, the scattered spectrum resources may be configured as one BWP.
In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application.
