Scheduling-free GF resource allocation method and related equipment

Abstract

The invention provides a scheduling-free GF resource allocation method and related equipment, which are used for reasonably allocating GF resources. The invention provides a scheduling-free GF resource allocation method comprising the steps that an intelligent management function unit IMF acquires feature information of a service; the IMF determines GF resource information corresponding to the feature information or GF resource indication information corresponding to the feature information; the IMF sends GF resource information or GF resource indication information to the base station or a management unit of the base station, the GF resource information is used for describing GF resources corresponding to the cell or GF resources corresponding to the network slice, the cell corresponds to the base station, the network slice corresponds to the base station, and the GF resource indication information is used for indicating the base station to determine the GF resource information or indicating the management unit to determine the GF resource information.

Description

technical field [0001] The present application relates to the communication field, and in particular to a scheduling-free GF resource allocation method and related equipment. Background technique [0002] Low-latency services are an important scenario in the fifth-generation mobile communication technology (5th-generation, 5G). When low-latency services are used for uplink data transmission, it is necessary to support grant-free (GF) data upload. In order to save the signaling interaction time of "sending a scheduling request by a user equipment (user equipment, UE)" and "sending an uplink data transmission resource indication to the UE", and achieving the low-latency index requirement. [0003] The existing solution is to manually allocate GF resource information for the cell or network slice in advance. The GF resource is used to describe the GF resource corresponding to the cell or network slice, and then download the GF resource information through the 5G base station (g...

Problems solved by technology

[0004] However, this GF resource allocation method has defects in practical applications. Since the GF resources corresponding to cells or network slices are fixed, on the one hand, when the number of UEs or data upload requirements are small, it will cause waste of redundant GF resources. On the one hand, when the number of UEs or data upload requirements are large, the pre-allocated GF resources obviously cannot satisfy all data uploads.
