Embodiment approach

[0222] a possible implementation

[0223] The interval of the SPS resource of BWP1 is configured as uplink N time units, and the time unit can be subframe (subframe), transmission time interval (Transmission Time Interval, TTI), time slot (slot), physical layer downlink control channel opportunity (Physical Downlink Control Channel occasion, PDCCH occasion), symbol (symbol), etc., for example, the SPS transmission resource interval is 6 symbols, which means that the continuous SPS resource interval is 6 symbols.

[0224] Optionally, the unknown start time position and end time of the SPS transmission opportunity corresponding to the SPS resource can be derived through a calculation formula, or the default configuration of the protocol. This embodiment does not limit the specific configuration method.

[0225] Optionally, the lengths of time units such as the subframe length, TTI length, Slot length, PDCCH occasion length, and Symbol length are related to the air interface form...

Abstract

The embodiment of the invention provides a communication method, device and equipment. The method comprises the steps: a terminal receives a BWP indication message sent by network equipment, the BWP indication message being used for indicating the terminal to activate a BWP and / or deactivate the BWP; and the terminal sends a BWP feedback message to a base station, wherein the BWP feedback messageis used for indicating that the terminal successfully receives the BWP indication message so that the problem of data transmission failure caused by different BWP communication adopted by the UE and the base station when the UE cannot receive or cannot correctly analyze the BWP indication message can be avoided and the communication quality is improved.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a communication method, device, and equipment. Background technique [0002] In a new generation wireless communication system (New Radio, NR), a concept of a bandwidth part (Bandwidth Part, BWP) is introduced. The frequency band of a cell can be divided into multiple sub-bands, and each sub-band can overlap. Each sub-band has a corresponding air interface format. Each sub-band can also have uplink and downlink control channels and data channels. Such a sub-band Bands are called BWP in NR. [0003] Each cell has an initial activation BWP, and the base station can notify the user equipment (User Equipment, UE) to perform the initial activation BWP through broadcast information, system information, etc. After the UE completes initial access to the cell through the initial activation BWP, it can be configured to different For example, there are BWP1 and B...
