Embodiment 2

[0071] The technical solution in the second embodiment is relatively simple and easy to implement, but also brings some problems. For example in Figure 6

[0072] Step S701: Receive the DCI sent by the base station, and determine the scheduling subband in the PUSCH.

[0083] For example, as shown in FIG. 10, K=4, N=9 (that is, 9 subbands are actually scheduled in the PUSCH), D=18, therefore,

[0085] The third type: the total frequency domain distance D is alternately divided into a first frequency domain segment and a second frequency domain segment. That is, the total frequency

[0092] Step S1201: Receive the DCI sent by the base station, and determine the scheduling subband in the PUSCH.

[0097] Further, step S1202 specifically includes the following two divisions:

[0109] Step 3: Execute step 2 cyclically until j is the last scheduled subband group.

[0110] As shown in FIG. 13 , D=18, K=4, N=9, and the frequency domain subbands corresponding to the scheduling subbands in ...

Abstract

The present invention introduces a method, device, device and readable storage medium for allocating scheduling subbands. The method includes: receiving downlink control information DCI sent by a base station, and determining scheduling subbands in a physical layer uplink shared channel PUSCH; According to at least one parameter in the total number of scheduling subbands in the PUSCH and the total frequency domain distance of the scheduling subbands in the PUSCH, and the total number of precoding indications in the DCI, establish the precoding indication in the DCI and the PUSCH The correspondence of the scheduling subbands in . The invention solves the instruction transmission problem of the precoding information of the uplink scheduling subbands, and notifies the precoding information of the uplink scheduling subbands whose number changes dynamically through the fixed precoding instruction in the DCI.

Description

Method, apparatus, device, and readable storage medium for allocating scheduling subbands technical field The present invention relates to the technical field of uplink transmission, in particular to a method, apparatus, equipment and Readable storage medium. Background technique At present, for uplink transmission, including codebook-based transmission (Codebook Based) and non-codebook-based transmission (Non‑codebook Based), NR (New Radio, new wireless technology) only supports DCI (Downlink Control Information, downlink control information) in the precoding indication to notify the precoding information of the wideband. For channel frequency selection For highly selective users, the precoding indication will bring performance loss. However, for how to indicate the precoding of the uplink scheduling subband code information, there is no good solution yet. SUMMARY OF THE INVENTION The main purpose of the present invention is to propose a method, apparatus, d...
