Embodiment 1

[0026] refer to figure 2 As shown in , an embodiment of the present application provides a method for determining available resources, which is applied to the above-mentioned communication system, and the method includes steps S101-S103:

[0027] S101. The first UE acquires semi-persistent scheduling (Semi-Persistent Scheduling, SPS) resource occupation transmission period and resource reselection counter information of the second UE.

[0028] Specifically, refer to image 3 As shown in , step S101 may include step S1011:

[0029] S1011, the first UE parses the physical shared control channel (Physical Sharing ControlChannel, PSCCH) of the second UE to obtain the space channel information format (Space Channel Information, SCI Format) 1 information, wherein, the SCI Format 1 information includes the SPS of the second UE Resource occupation transmission cycle and resource reselection counter information.

[0030] Specifically, the SPS resource occupation transmission period...

Embodiment 2

[0052] Taking the first UE as a mode 3 UE and the second UE as a mode 4 UE as an example, this embodiment of the present application provides another method for determining available resources, refer to Figure 5 As shown in , the method includes:

[0053] S201. The base station notifies the first UE to perform detection.

[0054] The base station may notify all or part of the first UEs that the first UEs are mode 3 UEs.

[0055] S202. The first UE parses the SCI Format 1 information in the PSCCH of the second UE to obtain the mode information, resource occupation priority information, SPS resource occupation transmission period, and resource reselection counter information of the second UE, and obtains the information according to the second UE's If the mode information determines that the second UE is a UE of mode 4, then step S203 is performed; otherwise, S202 is performed again.

[0056] S203. The first UE detects energy of the second UE to determine resources not occupi...

Embodiment 3

[0066] The embodiment of the present application provides a first UE 12 , including: an acquiring unit 1201 , a detecting unit 1202 , a determining unit 1203 , and a sending unit 1204 .

[0067] The obtaining unit 1201 is configured to obtain the semi-persistent scheduling SPS resource occupation transmission period and resource reselection counter information of the second UE, wherein the first UE is a UE of mode 3, and the second UE is a UE of mode 4, Alternatively, the first UE is a mode 4 UE, and the second UE is a mode 3 UE.

[0068] The detecting unit 1202 is configured to detect energy of the second UE to determine resources not occupied by the second UE within a detection period.

[0069] The determining unit 1203 is configured to determine available resources of the first UE according to the SPS resource occupation transmission period, resource reselection counter information, and resources not occupied by the second UE.

[0070] In a possible implementation manner, ...

Abstract

Embodiments of the present application provide a method, device, and system for determining available resources, which relate to the communication field and are used to resolve resource occupation conflicts between UEs in mode 3 and UEs in mode 4 when determining available resources. The method for determining available resources includes: the first user equipment UE obtains the semi-persistent scheduling SPS resource occupation transmission period and resource reselection counter information of the second UE, wherein the first UE is a mode 3 UE, and the second UE The UE is a UE of mode 4, or the first UE is a UE of mode 4, and the second UE is a UE of mode 3; the first UE detects the energy of the second UE to determine that no Resources occupied by the second UE; the first UE determines available resources of the first UE according to the SPS resource occupation transmission period, resource reselection counter information, and resources not occupied by the second UE . The embodiment of this application is applied to V2X communication.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, device and system for determining available resources. Background technique [0002] With the widespread application of mobile Internet, Internet of Things, and wireless sensing technologies, the Internet of Vehicles has become one of the key ways to realize future smart transportation and smart cities. Along with the research and formulation of the Long Term Evolution (LTE)-Vehicle to X (V2X) standard, the cellular network-based V2X technology has become another research hotspot in the Internet of Vehicles. [0003] For resource scheduling of user equipment (User Equipment, UE), LTE-V2X includes two resource scheduling modes, mode 3 (mode 3) and mode 4 (mode 4). UEs working in mode 3 have resources scheduled by the base station, and UEs working in mode 4 independently schedule resources according to resource occupancy. A UE can only be in one of mode 3 and mode 4 a...
