Embodiment 1

[0311] figure 2 The signaling flow of the BWP processing method provided by the embodiment of this application Figure 1 . Such as figure 2 As shown, the method includes:

[0312]S201. The network device sends the first information and the second information to the terminal.

[0313] S202. The terminal receives the first information and the second information sent by the network device.

[0314] Wherein, the first information is used to indicate that at least one default bandwidth part BWP corresponds to at least two active BWPs, and the second information is used to indicate that the at least two active BWPs correspond to at least one first timer.

[0315] Specifically, the first information is used to indicate a correspondence between each default BWP in at least one default BWP and an activated BWP, where each default BWP corresponds to at least two activated BWPs. That is, the first information is used to indicate the correspondence between each default BWP and an ...

Abstract

The embodiment of the present application provides a bandwidth part BWP processing method and device, including: the terminal receives the first information and the second information sent by the network device, the first information is used to indicate that at least one default bandwidth part BWP corresponds to at least two active state BWP, the second information is used to indicate that at least two BWPs in the activated state correspond to at least one first timer, and the first timer is used by the terminal to deactivate at least one BWP in the at least two BWPs in the activated state A timer for activation processing: according to the first information and the second information, the terminal performs deactivation processing on at least one BWP among at least two activated BWPs and performs activation processing on at least one BWP among the default BWPs, or performs at least At least one BWP among the two activated BWPs is deactivated. This embodiment provides an implementation manner of deactivation when there are multiple activated BWPs.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for processing a BWP of a bandwidth part. Background technique [0002] In the 5G new air interface (New Radio, NR), the system bandwidth, that is, the bandwidth of a carrier can become very large (such as 200MHz or 400MHz), and some terminals have limited capabilities and cannot support large bandwidth, so the network equipment will configure the terminal BWP (Bandwidth Part, BWP), that is, a part of the system bandwidth, such as 20MHz, on which the terminal can communicate with the network device. [0003] In order to reduce the power consumption of the terminal, the concept of BWP fallback (fallback) is also introduced in NR. Specifically, when a terminal is activated on a larger BWP, a timer is started to time the activation time of the larger BWP, and if the downlink control information (downlink control informa...
