Embodiment 1

[0201] Embodiment 1. A communication method, including:

[0202] The terminal device receives indication information from the network device, the indication information instructing the terminal device to work on the non-dormant bandwidth part BWP in the first secondary cell;

[0203] The terminal device enables the terminal device to work on a first BWP according to the indication information, and the first BWP is a non-dormant BWP in the first secondary cell.

Embodiment 2

[0204] Embodiment 2. The method as described in Embodiment 1, wherein the terminal device enables the terminal device to work on the first BWP, including:

[0205] The terminal device switches from the second BWP to the first BWP, where the second BWP is the dormant BWP or the non-dormant BWP currently used by the terminal device, and the first BWP is the first secondary cell within the first activated BWP.

Embodiment 3

[0206] Embodiment 3. The method as described in Embodiment 1, wherein the terminal device enables the terminal device to work on the first BWP, including:

[0207] The terminal device switches from the third BWP to the first BWP, where the third BWP is the dormant BWP or the non-sleep BWP currently used by the terminal device, and the first BWP is the BWP configured by the network device BWP to switch to.

Abstract

The invention relates to a communication method and a communication device, which are used for realizing that when terminal equipment receives indication information indicating to work on a non-dormant BWP in a certain auxiliary cell by network equipment, the terminal equipment can clearly determine which BWP works on and execute corresponding operation. The method comprises the steps of a network device generating indication information and sending the indication information to a terminal device, the indication information indicating the terminal device to work on a non-dormant BWP in a first secondary cell; and then, the terminal equipment enables the terminal equipment to work on a first BWP according to the indication information, and the first BWP is a non-dormant BWP in the first auxiliary cell. Therefore, when the terminal equipment receives the indication information indicating to work on the non-dormant BWP in a certain auxiliary cell by the network equipment, which BWP works on can be determined, and the terminal equipment works on the corresponding BWP.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] With the development of communication technology, carrier aggregation (CA) has been introduced into the standard. A terminal device can be configured with multiple component carriers (CC), and one CC corresponds to a primary cell (PCell), which is the terminal The cell where the device performs initial connection establishment, or the cell where radio resource control (radioresource control, RRC) connection reestablishment is performed, or the primary cell designated during a handover (handover) process. PCell is responsible for RRC communication with terminal equipment. Physical uplink control channel (physical up control channel, PUCCH) information can only be sent on the PCell. The remaining CCs correspond to secondary cells (secondary cells, SCells). [0003] When the terminal device is co...
