Embodiment Construction

[0063]The technical solution in this application will be described below with reference to the accompanying drawings.

[0064] The terms involved in this application are described in detail below:

[0065] 1. Beam:

[0066] A beam is a communication resource, and different beams can be regarded as different communication resources. Different beams can send the same information, or different information. A beam may correspond to at least one of time domain resources, space resources and frequency domain resources.

[0067] Optionally, multiple beams with the same or type of communication characteristics may be regarded as one beam, and one beam may include one or more antenna ports for transmitting data channels, control channels, and sounding signals. For example, the transmitting beam may refer to the distribution of signal strength formed in different directions in space after the signal is transmitted by the antenna; the receiving beam may refer to the distribution of si...

Abstract

The present application provides a method and device for determining cell activation delay. The method includes: the terminal device or the network device can respectively determine the activation delay corresponding to the cell to be activated according to whether the downlink spatial filtering of the downlink signal of the cell to be activated is the same or different from the downlink spatial filtering of the downlink signal of the activated cell. In this way, the terminal device sends the CSI within the activation delay, and the network device receives the CSI within the activation delay, and judges whether the cell to be activated is successfully activated according to whether the CSI is received. That is to say, in the embodiment of the present application, the terminal device and the network device can determine a reasonable activation delay, so as to prevent the terminal device and the network device from misjudging whether the secondary cell is successfully activated due to the activation delay being too long or too short, so as to ensure that the device Under the premise of reducing power consumption, the success rate of cell activation is improved.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a method and device for determining cell activation delay. Background technique [0002] In a new radio interface (new radio, NR), a terminal device will perform initial access in a primary cell (primary cell, PCell) after being turned on. Afterwards, the network device may carry configuration parameters of a secondary cell (secondary cell, SCell) through configuration signaling or resource control (radio resource control, RRC) configuration, so as to add an SCell for the terminal device. [0003] Specifically, the network device can dynamically decide to configure the SCell for the user based on an internal algorithm, and issue SCell activation signaling to the terminal device through media access control (media access control, MAC)-control element (control element, CE) signaling. The terminal device activates the corresponding SCell according to the activation sign...
