Embodiment approach

[0093] When the first DCI scheduled SL cell or carrier, it is understood that the number of SIZEs of the SL cell or carrier does not exceed M2, which is 1 or 2, that is, scheduled the SL cell or The number of SIZEs of the carrier does not exceed 1 or 2.

[0094] It should be understood that the DCI Size budget of the first object may be a network device configuration, preconfiguration, protocol definition, other user instructions, or the user's own choice.

[0095] Alternatively, the first object can be a network device configuration, preconfiguration, protocol definition, other user instructions or users themselves.

[0096] Alternatively, if the first object and / or the DCI Size budget of the first object is pre-configured, other users indicate or the user itself, the user can also report the first object and / or the first object DCI Size budget .

[0097] Alternatively, the second bit of the second bit of the second DCI is the number of bits of the target DCI corresponding to...

Embodiment 1

[0166] Each target object has its own corresponding target DCI Size, which contains at least one of the following items.

[0167] A, the target DCI size corresponding to each BWP pair;

[0168] B, configure the target DCI size for each UL BWP;

[0169] C, configure the target DCI size for each DL BWP

[0170] D, configure the target DCI size for each SL BWP

[0171] For A, optionally, the BWP pairing can be pairing UL BWP and DL BWP. For example, the BWP ID of the UL BWP and DL BWP can be considered to be a BWP pair, and the BWP pair of BWP pairs corresponding to different BWP IDs respectively configure the corresponding target DCI size, respectively. Alternatively, for the corresponding target DCI size, there is only the DL BWP of BWPID = 4 without the presence of the DL BWP of BWPID = 4, and the BWP ID = 4 does not have a BWP pair, so that There is a target DCI size that configures BWP ID = 4.

[0172] For A, optionally, the BWP pairing can be paired by SL BWP and UL BWP. For ex...

Embodiment 2

[0180] Embodiment 2, determine the target DCISize in accordance with the BWP to determine the target DCISize in the case of the BWP switching, thereby determining the SL DCI Size.

[0181] The user determines the SL DCI Size based on the target object that the current user is activated. The specific may include at least one of the following:

[0182] The user determines the corresponding SL DCI Size according to the target DCI size corresponding to the currently activated BWP pair;

[0183] The user determines the corresponding SL DCI Size according to the target DCI size corresponding to the currently activated UL BWP;

[0184] The user determines the corresponding SL DCI Size according to the target DCI size corresponding to the currently activated DL BWP;

[0185] The user determines the corresponding SL DCI Size based on the target DCI Size corresponding to the currently activated SL BWP.

[0186] Alternatively, when the target object is switched, the user determines the SL DC...

Abstract

Provided are a Downlink control information (DCI) transmission method and communication equipment, and the method comprises the steps: acquiring a first bit number of a first DCI, the first DCI being a bypass downlink control information SL DCI; determining a third bit number of the first DCI according to the first bit number and a second bit number of the second DCI; and transmitting the first DCI according to the third bit number. According to the embodiment of the invention, the determination mode of the bit number of the SL DCI is defined, so that the understanding consistency of the network equipment and the terminal is kept.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to a DCI transmission method and a communication device. Background technique [0002] In the New Radio, NR) V2X system, two resource allocation modes are supported, respectively, respectively, respectively, and the autonomous resourceselection mode, respectively. Among them, the scheduling resource allocation mode is often referred to as MODE-1. In the scheduling resource allocation mode, it is usually controlled by the network device and allocates resources for each terminal, and the resource is selected by the terminal in autonomous resource selection mode. [0003] In the case where the network device controls the SL resource (for example, MODE-1), the network device can scheder or activate or activate the side link (SIDELINK, SL) resources through downlink control information (DCI). Define new DCI formats for scheduling or activating SL resources. Among them...
