Systems and methods for configuration signaling

摘要

A User Equipment (UE) for receiving time-division duplexing (TDD) uplink/downlink (UL/DL) configurations is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE receives a first TDD UL/DL configuration for a cell and secondary configuration information that includes at least a second TDD UL/DL configuration for the cell.

1. A user equipment (UE) for receiving time-division duplexing (TDD) uplink/downlink (UL/DL) configurations, comprising:
a processor; and non-transitory memory in electronic communication with the processor, wherein instructions stored in the memory are executable to cause the processor to:
receive a first time-division duplexing (TDD) uplink/downlink (UL/DL) TDD UL/DL configuration for a cell and secondary configuration information that comprises at least a second TDD UL/DL configuration for the cell, wherein supported combinations of the first TDD UL/DL configuration and the second TDD UL/DL configuration are defined and not all combinations of the first TDD UL/DL configuration and the second TDD UL/DL configuration are supported;determine a downlink (DL)-reference TDD UL/DL configuration based on the second TDD UL/DL configuration which is signaled in a radio resource control (RRC) message;perform Physical Downlink Shared Channel (PDSCH) operations based on at least the DL-reference TDD UL/DL configuration;determine an uplink (UL)-reference TDD UL/DL configuration based on the first TDD UL/DL configuration which is signaled in a system information block (SIB) or an RRC message; andperform Physical Uplink Shared Channel (PUSCH) operations based on at least the UL-reference TDD UL/DL configuration.
