发明名称 TRANSMISSION OF ACKNOWLEDGEMENT INFORMATION IN ADAPTIVELY CONFIGURED TDD COMMUNICATION SYSTEMS
摘要 Methods and apparatus of a base station or a User Equipment (UE) in communication with each other are provided. The UE is configured by the base station for operation with an adapted Time Division Duplex (TDD) UpLink-DownLink (UL-DL) configuration. A process enabling transmission of acknowledgement information from the UE for communication in two different sets of DL Transmission Time Intervals (TTIs) is provided.

主权项 1. A method comprising: configuring, by a base station to a User Equipment (UE) a first Time Division Duplex (TDD) UpLink-DownLink (UL-DL) configuration, a second TDD UL-DL configuration, and a third TDD UL-DL configuration; and transmitting, by the base station to the UE in a DL or special SubFrame (SF) of the third TDD UL-DL configuration, either a Physical DL Control CHannel (PDCCH) or an Enhanced PDCCH (EPDCCH) conveying a DL Control Information (DCI) format that schedules to the UE either a reception of a Physical DL Shared CHannel (PDSCH) or a release of a Semi-Persistently Scheduled (SPS) PDSCH in the DL or special SF, wherein if the DCI format is conveyed by the EPDCCH it includes an Acknowledgement Resource Offset (ARO) field, wherein, in response to receiving the first TDD UL-DL configuration, the second TDD UL-DL configuration, and the third TDD UL-DL configuration, the UE: determines, according to the second TDD UL-DL configuration, an UL SF to transmit acknowledgement information in response to at least one reception of PDSCH or SPS PDSCH release in a set of DL or special SFs of the third TDD UL-DL configuration;receives a number of PDSCHs and SPS PDSCH release in a subset of the set of DL or special SFs;determines: acknowledgement information for the set of DL and special SFs in response to at least the reception of the number of PDSCHs and SPS PDSCH release in the subset of the set of DL or special SFs,a first subset of the set of DL or special SFs that are DL or special SFs in the first TDD UL-DL configuration for which acknowledgement information is transmitted in the UL SF and a second subset of the set of DL or special SFs comprising of DL or special SFs that are not in the first subset; anda first set of resources and a second set of resources in the UL SF, wherein a resource in the first set of resources corresponds to a SF in the subset that is in the first subset wherein the resource is determined either using a first offset if the reception is scheduled by a PDCCH or using the ARO field and a second offset if the reception is scheduled by an EPDCCH;a resource in the second set of resources corresponds to a SF in the subset that is in the second subset wherein the resource is determined using a third offset if the reception is scheduled by a PDCCH or using the ARO field and the second offset if the reception is scheduled by an EPDCCH;selects, from the first set of resources or from the second set of resources, a resource of a physical UL control channel to transmit the acknowledgement information, wherein the resource is selected based on the values of the acknowledgement information; andtransmits, to the base station, the acknowledgement information in the selected resource.
