The invention discloses a scheduling-free-based resource selection method and device, and relates to the technical field of wireless communication. The scheduling-free-based resource selection methodcomprises the steps that a base station divides scheduling-free resources into a preferred resource section and a candidate resource section; the base station allocates resources in the preferred resource section for users in advance; the base station configures resources in the candidate resource section as a resource pool for the users to select when sending data; and selecting the resources allocated to the users in the preferred resource section and / or the resources in the resource pool for data transmission according to the data volume required to be sent. The method and device avoid thewaste of reserved resources in scheduling-free transmission, and reduces the probability of resource collision.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a scheduling-free resource selection method and device. Background technique [0002] The 5G system needs to support higher data rates and lower latency, and provide and guarantee a better experience for each user in the network. In low-latency and high-reliability scenarios, services such as Internet of Vehicles, telemedicine, and industrial control require end-to-end latency to be as low as 0.5ms. [0003] In order to meet the low-latency requirements in low-latency and high-reliability scenarios, the 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) standardization organization proposed a scheduling-free transmission mechanism for uplink, that is, users will not receive scheduling from the base station signaling. Existing scheduling-free resource selection methods mainly include: the base station allocates resources for us...
