US 2022/0030606 A1 · ENHANCED REPETITION MECHANISM FOR PHYSICAL UPLINK CONTROL CHANNEL

Abstract

An apparatus and system to provide an enhanced repetition mechanism for PUCCH coverage enhancement are described. The resource allocation and handling mechanisms for collisions with semi-static downlink symbols and invalid symbols are described. The UE receives a PUCCH resource in RRC signalling. The PUCCH resource includes a starting symbol and number of symbols of a PUCCH repetition in a slot and a repetition factor that indicates a number of repetitions. For contiguous repetitions, a repetition that crosses a slot boundary is dropped or segmented. A segmented portion equal to 3 symbols is not transmitted.

Dependent claims

An apparatus for a 5th generation NodeB (gNB), the apparatus comprising:

processing circuitry configured to:
encode, for transmission to a user equipment (UE), a control signal that indicates a physical uplink control channel (PUCCH) resource, the PUCCH resource comprising at least one time domain resource allocation (TDRA) for repetitions of a PUCCH and an indication of a number of repetitions of the PUCCH, and
decode, from the UE, a particular PUCCH having repetitions in accordance with the PUCCH resource;
and
a memory configured to store the PUCCH resource.
