Abstract

The embodiment of the invention provides a PDCCH and PDSCH scheduling control method and device. The method applied to a base station comprises the steps of sending a first PDCCH carrying first DCI toa terminal through a single sub-band, wherein the first DCI carries a starting sub-band number and the maximum sub-band aggregation level of a second PDCCH, and the second PDCCH is sent through multiple sub-bands; according to the starting sub-band number and the maximum sub-band aggregation level of the second PDCCH, sending the second PDCCH carrying second DCI to the terminal through the multiple sub-bands, wherein the second DCI carries the PDSCH starting sub-band number and the occupied sub-band number when the PDSCH is sent; and sending the PDSCH to the terminal according to the PDSCH starting sub-band number and the occupied sub-band number. The embodiment of the present invention solves the problem in the prior art that the PDCCH scheduling efficiency and the system overhead cannotbe both considered when the PDCCH and the PDSCH are scheduled in any combination.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a scheduling control method and device for PDCCH and PDSCH. Background technique [0002] In the existing power wireless private network application scenarios, when multi-subband transmission is used, in order to support low-latency application scenarios, it is necessary to support Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) are scheduled in the same frame; in addition, in order not to reduce the demodulation performance of PDCCH, it is necessary to support subband aggregation; in addition, in order to improve system efficiency, PDCCH should not occupy too many resources. [0003] Among them, PDCCH is distributed on multiple subbands, using adaptive subband aggregation to improve link performance, and PDSCH is also distributed on multiple subbands, using frequency ...
