Title:
DEVICES FOR RECONFIGURING UPLINK AND DOWNLINK ALLOCATIONS
Document Type and Number:
WIPO Patent Application WO/2013/111607
Kind Code:
A1
Abstract:
A User Equipment (UE) for reconfiguring uplink and downlink (UL-DL) allocations is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE determines whether at least one subframe is convertible over a default Time Domain Duplexing (TDD) UL-DL configuration. If at least one subframe is convertible, then the UE determines a first reference UL-DL configuration and a second reference UL-DL configuration. The UE also sends any hybrid automatic repeat request acknowledgement (HARQ-ACK) information corresponding to a Physical Downlink Shared Channel (PDSCH) based on the first reference configuration. The UE further determines a Physical Uplink Shared Channel (PUSCH) schedule based on the second reference UL-DL configuration. The UE additionally receives any hybrid automatic repeat request acknowledgement (HARQ-ACK) information corresponding to a Physical Uplink Shared Channel (PUSCH) based on the second reference UL-DL configuration.
