Problems solved by technology
However, when the number of UEs is relatively large, due to contention conflicts, that is, collision problems caused by multiple UEs competing for the same contention opportunity, the resource utilization efficiency will also drop rapidly.

Embodiment Construction
[0057] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.
[0058] figure 1 It is a flow chart of the method for acquiring and sending data resources of the present invention, such as figure 1 Shown, including:
[0059] Step 100: Obtain a resource request index and a set of competition opportunities.
[0060] In this step, the resource request index and contention opportunity set are allocated to the UE by the network such as the base station.
[0061] Among them, the resource request index is used to correspond to a resource that the UE can send data.
[0062] One or more competitive opportunities are included in the set of competitive opportunities. ...

The invention discloses a method and a device for acquiring and sending data resources, including acquiring a resource request index and a set of competition opportunities; acquiring the maximum number of competitions using the set of competition opportunities; The UE participates in the competition opportunity of the competition, and uses the competition opportunity to obtain resources for sending data. Through the method of the present invention, the UE can only participate in the competition of the competition opportunity set after obtaining the information of the maximum number of competitions. Therefore, based on the method of the present invention, the collision problem caused by the competition of multiple UEs for the same competition opportunity, namely competition, can be easily reduced by adjusting the time of sending the maximum number of competitions or the setting of the maximum number of competitions for different UEs. conflict. At the same time, signaling overhead and processing delay caused by the network side scheduling resources for the UE are also avoided, thereby improving resource utilization.
Description
Technical field [0001] The present invention relates to a wireless communication system resource management technology, in particular to a method and device for acquiring transmission data resources. Background technique [0002] In a wireless communication system, when user equipment (UE, User Equipment) or machine terminal equipment (for simplification, the UE is described below) needs to send data, it first needs to obtain the resources for sending the data. In the prior art, the UE Resources are usually obtained in one of two ways: [0003] One way to obtain transmission data resources is that the UE first applies for resources from the network, and the network sends authorization for the UE by means of scheduling; the UE detects the authorization, and then obtains the resources allocated by the network to itself according to the authorization instructions. The disadvantage of this method is that it requires more signaling overhead and processing delay. In addition, when the ...
