Abstract
Systems and methods for interlace PUCCH transmission in 5G networks are described. The gNB sends an RRC message to a UE. The RRC message provides one or more PUCCH interlace allocations within a BW. Each PUCCH interlace allocation has a PUCCH format for each PUCCH interlace. Each PUCCH format contains a different PUCCH interlace index. The UE sends a PUCCH interlace in the BWP based on the PUCCH interlace allocation. A PUCCH in the allocated PUCCH interlace has a cyclic shift that is dependent on a resource block number in the allocated PUCCH interlace within the BWP.
Claims19
An apparatus for a 5th generation NodeB (gNB), the apparatus comprising:
- processing circuitry configured to:
- encode, for transmission to a user equipment (UE), a radio resource control (RRC) message comprising a physical uplink control channel (PUCCH) interlace allocation, the PUCCH interlace allocation providing a PUCCH resource within the PUCCH interlace allocation within a bandwidth part (BWP), and
- decode, from the UE, a PUCCH in the BWP based on the PUCCH interlace allocation, the PUCCH having a cyclic shift dependent on a resource block number of a resource block, within the PUCCH interlace allocation, used for transmission of the PUCCH;
- and
- memory configured to store the RRC message.
A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a 5th generation NodeB (gNB), the instructions when executed configure the one or more processors to:
- encode, for transmission to a user equipment (UE), a radio resource control (RRC) message comprising a physical uplink control channel (PUCCH) interlace allocation for each of multiple PUCCH interlaces within a bandwidth part (BWP), the PUCCH interlace allocation providing a PUCCH resource within the PUCCH interlace allocation;
- and decode, from the UE, a PUCCH in the BWP based on the PUCCH interlace allocation, wherein the PUCCH has a cyclic shift α1 dependent on a resource block number of a resource block, within the PUCCH interlace allocation, used for transmission of the PUCCH.
A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE), the instructions when executed configure the one or more processors to:
- decode, from a 5th generation NodeB (gNB), a radio resource control (RRC) message comprising a physical uplink control channel (PUCCH) interlace allocation, the PUCCH interlace allocation providing a PUCCH resource within the PUCCH interlace allocation within a bandwidth part (BWP);
- and encode, for transmission to the gNB, a PUCCH in the BWP based on the PUCCH interlace allocation, the PUCCH having a cyclic shift dependent on a resource block number of a resource block, within the PUCCH interlace allocation, used for transmission of the PUCCH.
