Embodiment 1

[0085] Figure 5 A schematic flowchart of a method for monitoring a PDCCH provided by the present invention is shown. The solution provided by the embodiment of the present invention is aimed at a scenario where a network device configures one or more BWPs for a terminal, and the terminal is in a BWP working mode. The method specifically includes:

[0086] S201. The network device determines configuration information of at least one CORESET.

[0087] Wherein, the at least one CORESET mentioned above can be configured in units of carriers, or can be configured in units of BWPs. Specifically, when at least one CORESET is configured in units of carriers, at least one CORESET is configured on a carrier, and each carrier is configured with The number of CORESETs can be different, which is not limited here; when at least one CORESET is configured in units of BWPs, a BWP is configured with at least one CORESET, and the number of CORESETs configured by each BWP can be different, whi...

Embodiment 2

[0092] Image 6 A schematic flowchart of a method for monitoring a PDCCH provided by the present invention is shown. This embodiment is aimed at the scenario where the terminal is in the BWP working mode. When monitoring the PDCCH in at least one CORESET, the terminal needs to determine the CORESET to be monitored from all configured CORESETs. The process for the terminal to determine the CORESET to be monitored from the configured CORESETs can be implemented in two ways. Therefore, in this embodiment, on the basis of S201 to S203 provided in Embodiment 1, S203 may be replaced by S303a, or S203 may be replaced by S303b1 and S303b2 according to different implementation manners.

[0093] Such as Image 6 As shown, method 1: implicit determination method (that is, the terminal implicitly determines the CORESET to be monitored according to the corresponding relationship between CORESET and BWP)

[0094] Specifically, replacing S203 with S303a, the method includes:

[0095] S3...

example 1

[0102] Example 1: When the CORESET is configured based on the carrier, the terminal determines at least one complete CORESET that falls within the BWP that the terminal currently accesses in the CORESET set on the carrier where the terminal is currently located, and the determined complete CORESET Monitor PDCCH in CORESET.

[0103] For example, if Figure 7 As shown, CORESET is configured according to the carrier, and there are 3 CORESETs configured on the carrier ( Figure 7 CORESET1, CORESET2, CORESET3), if CORESET1 falls into the BWP1 currently accessed by the terminal, and CORESET1 in BWP1 is a complete CORESET. Then the terminal only needs to monitor CORESET1 falling into BWP1. When the terminal determines the CORESET that needs to be monitored in BWP1, the terminal can determine implicitly according to the corresponding relationship between CORESET and BWP, that is, determine the CORESET that falls within the bandwidth of BWP1, or send an instruction message from the n...

Abstract

The invention discloses a method for monitoring a PDCCH, a terminal and a network device, relates to the technical field of wireless communication, and introduces how to configure a terminal to monitor a PDCCH in a scenario where a network device configures one or more BWPs for a terminal. The method includes: determining configuration information of at least one control resource set CORESET; sending the configuration information of the at least one CORESET to the terminal; where at least one CORESET is configured in units of carrier or partial bandwidth BWP; the carrier includes at least one BWP; When at least one CORESET is configured in units of carriers, at least one CORESET is configured in one carrier; when at least one CORESET is configured in units of BWPs, at least one CORESET is configured in one BWP.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for monitoring a PDCCH, a terminal and a network device. Background technique [0002] In the 5G (NR (new radio)) system, a large bandwidth (for example, greater than or equal to 100MHZ) is usually used to transmit data. Since terminals have different bandwidth capabilities, in order to enable a terminal with a small bandwidth capability to access a part of bandwidth in a large bandwidth network, a concept of a bandwidth part (BWP) is introduced in the NR system. In the NR system, a terminal can be configured with one or more BWPs. When the terminal is configured with multiple BWPs, each BWP can adopt the same or different numerical configuration (numerology), so that the terminal can access the BWP of the large-bandwidth network. . For the scenario where the network device configures one or more BWPs for the terminal, the issue of the terminal m...
