Transmission of uplink control information for coordinated multi-point reception

摘要

Methods and apparatus for a User Equipment (UE) to determine a number of coded modulation symbols per spatial layer for an Uplink Control Information (UCI) type it multiplexes in a Physical Uplink Shared CHannel (PUSCH) is provided. The UE communicates with different sets of Reception Points (RPs) in different Transmission Time Intervals (TTIs) wherein two RPs in a same set of RPs have a communication latency that is smaller than or equal to a predetermined value and two RPs in two different respective sets of RPs have a communication latency that is larger than a predetermined value.

1. A method for transmitting an uplink control information (UCI) type by a user equipment (UE), the method comprising:
receiving higher layer signaling information including a plurality of offset values {βoffset,1UCI-type, Λ, βoffset, NRPUCI-type} corresponding to sets of reception points (RPs) (NRP), the plurality of offset values being used for transmitting the UCI to at least two base stations; determining a number of coded modulation symbols per spatial layer Q′ for the UCI type based on the offset value βoffset, nRPUCI-type corresponding to a set of RPs (nRP) determined from the sets of RPs (NRP), the sets of RPs (NRP) including the set of RPs (nRP); multiplexing per spatial layer the Q′ coded modulation symbols for the UCI type in a physical uplink shared channel (PUSCH); and transmitting the PUSCH.
