System and method for an uplink control signal in wireless communication systems

摘要

A user equipment is capable of receiving communications from a cell including at least one base station. The user equipment includes a receiver configured to receive from the base station both a cell specific radio resource control (RRC) configuration comprising a cell specific resource offset parameter for a PUCCH HARQ-ACK, and a UE specific RRC configuration comprising a UE specific RS base sequence parameter and an UE specific resource offset parameter for the PUCCH HARQ-ACK.

1. A method for communication between a User Equipment (UE) and a Node B (NB), the method comprising:
receiving, from the NB, a common radio resource control (RRC) configuration information comprising a common resource offset parameter for a physical uplink control channel (PUCCH) and a UE specific RRC configuration information comprising a UE specific resource offset parameter for the PUCCH; receiving, from the NB, a downlink (DL) control information (DCI) on one of a physical downlink control channel (PDCCH) constructed by at least one channel control element (CCE) and an enhanced physical downlink control channel (ePDCCH) constructed by at least one enhanced channel control element (eCCE); receiving data on a physical downlink shared channel (PDSCH) associated with the PDCCH or the ePDCCH; identifying a PUCCH resource, nPUCCH(1), based on
nPUCCH(1)=nCCE+NPUCCH(1),where nCCE is a number of a first CCE used for transmission of the DCI and NPUCCH(1) is one of the UE specific resource offset parameter and a cell specific resource offset parameter;
identifying at least one orthogonal cover and at least one cyclic shift based on the PUCCH resource, nPUCCH(1); and transmitting a hybrid automatic repeat request acknowledge (HARQ-ACK) on the PUCCH based on the PUCCH resource, nPUCCH(1), the at least one orthogonal cover, and the at least one cyclic shift.
