Abstract:
Aspects of the disclosure provide a method for physical broad-cast channel (PBCH) processing at a base station (B S) in a wireless communication system. The method can include performing a channel coding process to generate encoded PBCH data at the BS. The encoded PBCH data is to be carried in a synchronization signal block (SS block) having an SS block index (SBI), and transmitted from a cell having a cell ID. The method can further include performing a second scrambling over the encoded PBCH data with a second scrambling code determined based on the cell ID and the SBI to generate second scrambled PBCH data.
Abstract:
The embodiments of this invention propose methods of physical resource allocation for UL control channels including PUCCH and PRACH in adaptive TDD systems. In an adaptive TDD system, there are multiple types of UL-DL configuration, e.g. System configuration, UL-reference configuration (same to System configuration), DL-reference configuration (different from System configuration) and actual configuration. If legacy UE and eIMTA UE respectively follow System configuration and DL-reference configuration to feedback DL HARQ-ACK and corresponding PUCCH resources are implicitly determined by CCE index, PUCCH resource collision may happen, i.e. multiple PUCCHs are transmitted in single resource. The problem of PUCCH resource collision will cause PUCCH performance degeneration and needs to be resolved. Some solutions are proposed in the invention to resolve this problem.
