Resource sharing method and device

Abstract

The invention provides a resource sharing method and device, and the method is suitable for single-cell PRB resource sharing of an NB-IoT system, and comprises the steps: obtaining PRB release information of a first physical resource module; according to the first PRB release information, releasing a static configuration relationship between the first uplink non-anchor PRB and the first downlink non-anchor PRB; an selecting an uplink non-anchor PRB conforming to an application rule from the at least one uplink non-anchor PRB and a downlink non-anchor PRB conforming to the application rule fromthe at least one downlink non-anchor PRB to form a first configuration relationship for data transmission, wherein the at least one uplink non-anchor PRB comprises a first uplink non-anchor PRB, andthe at least one downlink non-anchor PRB comprises a first downlink non-anchor PRB. The combination of each uplink non-anchor PRB and a plurality of downlink non-anchor PRBs is realized; each downlinknon-anchor PRB is combined with a plurality of uplink non-anchor PRBs, so that the NB-IoT system can freely combine the uplink and downlink non-anchor PRBs according to configuration requirements, light load or no load of PRB resources is avoided, and the utilization rate of the PRB resources is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource sharing method and device. Background technique [0002] With the rapid development of the Internet of Things, major operators around the world have taken the Internet of Things as a key development strategy, in order to help operators quickly seize the Internet of Things market and reuse LTE network infrastructure. Narrow Band Internet of Things (NB-IoT) technology has been proposed, and NB-IoT system technology has the characteristics of low cost, low power consumption, wide coverage and large connection. [0003] In the NB-IoT system, since the deployment bandwidth is 180kHz, which is the same as the bandwidth of a Physical Resource Block (PRB) in the LTE system, the 3GPP standard introduces the multi-carrier (Multi-PRB) ) design, and the PRB type is divided into anchor carrier (Anchor PRB) and non-anchor carrier (Non-Anchor PRB). Among them...

Problems solved by technology

[0004] In NB-IoT deployment scenarios, usually a cell has only one anchor PRB and can carry multiple non-anchor PRBs. These NB-IoT carrier resource configurations are deployed through static configuration, which means that if the carrier After resources are occupied by NB-IoT configuration, other systems (such as LTE) cannot be used. For the scenario where NB-IoT anchor PRB or non-anchor PRB is deployed in the LTE band, such a static configuration deployment method will lead to The available resources of LTE are reduced, which reduces the system capacity of LTE
