Problems solved by technology

This communication mode also has two disadvantages. One is that the spectrum of D2D communication needs to be allocated by the network side, which requires a large amount of signaling overhead, which puts a heavy load on the network side; The communication spectrum cannot be re-allocated to other UEs, or the spectrum is rarely reused by other UEs, which is not conducive to the spatial multiplexing of resources and reduces the utilization rate of the spectrum

Embodiment 1

[0101] figure 2 It is a flowchart of a method for selecting a communication mode according to another embodiment of the present invention. Such as figure 2 As shown, the communication performance parameter is an average spectrum occupancy rate, and the average spectrum occupancy rate represents an average value of the spectrum occupancy rate within a predetermined time range. The communication mode selection method includes the following steps:

[0102] Step S210, the user equipment sets a threshold of spectrum occupancy;

[0103] Step S220, the user equipment obtains an average spectrum occupancy rate;

[0104] Step S230, the user equipment compares the obtained average spectrum occupancy rate with the set threshold of spectrum occupancy rate, wherein, if the average spectrum occupancy rate is greater than the threshold of the average spectrum occupancy rate, it means that the first The first mode is better than the second mode, that is, enter step S230Y if the obtained...

Embodiment 2

[0113] image 3 It is a flowchart of a method for selecting a communication mode according to yet another embodiment of the present invention. Such as image 3 As mentioned above, the main difference from the previous embodiment is that the communication performance parameter is the number of user equipments, and the number of user equipments indicates the number of other user equipments around the user equipment that can be detected by the user equipment; For communication performance parameters, determining the D2D communication mode of the user equipment may mainly include the following steps:

[0114] Step S310, the user equipment sets a threshold of the number of user equipments;

[0115] Step S320, the user equipment obtains the number of user equipment;

[0116] Step S330, the user equipment compares the obtained number of user equipments with the set threshold of the number of user equipments, wherein, if the number of user equipments is greater than the threshold o...

Abstract

The invention discloses a communication mode selection method and user equipment. The communication mode selection method comprises the steps that the user equipment acquires communication performance parameters; and a D2D communication mode of the user equipment is confirmed according to the acquired communication performance parameters, wherein the D2D communication mode comprises a first mode and a second mode, the user equipment performs D2D communication by utilizing communication spectrum resource allocated by a network under the first mode, and the user equipment selects the shared communication spectrum resource to perform D2D communicated under the second mode. According to the communication mode selection method and the user equipment provided by the embodiment of the invention, D2D communication performance and communication spectrum resource utilization rate can be both considered effectively, and realization is easy.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a communication mode selection method and user equipment. Background technique [0002] In the past 20 years, wireless communication technology has achieved great development, and wireless communication network has become an indispensable part of people's life. However, with the rapid increase in the number of people using wireless communication networks and the increasing performance requirements for wireless communication networks, limited wireless spectrum resources have become the key to limiting wireless communication performance. [0003] Currently, the cellular network is the main wireless communication network. In the communication based on the cellular network, the communication between two user equipment needs to be forwarded by the base station, that is, the same data packet needs to occupy space resources at least twice from the user equipment ...
