Problems solved by technology
[0013] However, the inventors of the present invention found that, based on this solution, the scheme of DAI equal to 3 or 4 cannot be supported for the uplink DAI, and the coordinated scheduling of two uplink subframes cannot be supported for the uplink index
Therefore, the degree of freedom of scheduling is limited

The invention involves a method of the uplink link index domain used to configure the downlink links in EIMTA in the base station of the dual -worker wireless communication system in time.The road reference configuration is one in the configuration collection of {2, 4, 5}. This method includes the four downlink links that configure the time dual -time -shaped to {0} are divided into the first sub -frame group and the second group and the second second group and the second.Sub -frame packets; configure the uplink link in the uplink resource scheduling in the downlink link of the first sub -frame group to DAI, to indicate the PDCH sub -frame number and downlink semi -static scheduling PDCCHThe sum of the number of sub -frames; and configure the uplink link index in the uplink link resources in the uplink link resources of the secondary frame group to the first upward link index.According to the method of the present invention, the existing resources can be used to provide UL index and UL DAI at the same time, thereby improving the efficiency of resource utilization and meeting the corresponding needs.
Description
Technical field [0001] The present invention relates to communication technology, and in particular, to a method for configuring an uplink index field in a downlink subframe for eIMTA in a base station of a time division duplex wireless communication system. Background technique [0002] Under the Rel-12 version of TDD (Time Division Duplexing: Time Division Duplexing) eIMTA (enhanced Interference Management and Traffic Adaptation: Enhanced Interference Management and Traffic Adaptation) work item (Work Item: WI), the following consensus has been reached: [0003] -For the uplink, its scheduling and HARQ time slots follow the TDD UL-DL configuration defined in SIB1; [0004] -The downlink HARQ reference configuration can be selected from the TDD UL-DL configuration {2, 4, 5} of the Rel-8 version. [0005] In today's TDD standard, for TDD configuration {0}, a 2-bit uplink index field in uplink resources is used to perform multi-subframe scheduling. As shown in section 8.0, for TDD UL / ...
