Abstract

The invention discloses an uplink resource determining method and system. The method comprises the following steps: a base station sending resource configuration parameters to user terminals, wherein the resource configuration parameters comprise N (1, PUCCH); the base station sending PDCCH control signalings and corresponding PDSCH data to the individual user terminals, and sending G-PDCCH control signalings and corresponding PDSCH data to a user terminal group; the user terminals, according to types of the received control signalings, obtaining indexes nCCE of first control channel elements (CCEs) occupied by corresponding control channels; and the user terminals detecting PDSCHs, by use of the indexes nCCE, the resource configuration parameters and corresponding offset amounts, determining uplink resources of ACK / NACK, and feeding the ACK / NACK back on the determined uplink resources. The method and system effectively solve the problem of uplink ACK / NACK resource conflicts.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for determining uplink resources. Background technique [0002] It is estimated that by 2020, mobile data traffic will increase by 500-1000 times compared to 2010, and the 5G system needs to increase the network capacity accordingly to meet the explosive growth demand of data services. However, high-bandwidth applications such as ultra-high-definition video, video conferencing, massive data sharing, and 3D games place higher demands on communication rates. The 5G system needs to support higher data rates to support future large-bandwidth services, and provide and guarantee a higher and fairer rate experience for each user in the network. [0003] In addition, the future network will face the contradiction between a surge in capacity demand and a shortage of spectrum. 5G needs to further improve spectrum utilization efficiency, including improving air interfa...
