Multiple uplink control channel transmission with reduced cubic metric

摘要

It is determined that there are X uplink control channel resources available for uplink signaling. Each of those X uplink control channel resources are sub-channelized into a plurality of sub-channels that each defines a unique time instant or point in time. For each of Y units of control information there is selected a unique combination of one of the sub-channels and a modulation (X and Y are each integers greater than one). The Y units of control information are sent on the X uplink control channel resources according to the respectively selected combinations. By example the uplink resources may be an ACK/NAK/DTX bit on a PUCCH. In one example the sub-channels are individual slots of a PUCCH. In another example the sub-channels are the reference-signal part and the data part of a single PUCCH slot.

1. An apparatus comprising:
at least one processor; and at least one memory storing computer program instructions; in which the at least one memory, with the computer program instructions, is configured with the at least one processor to cause the apparatus at least to:
determine that there are already assigned uplink control channel resources available for uplink signaling;sub-channelize each of the assigned uplink control channel resources into a plurality of sub-channels to support an increased number of bits on the assigned uplink control channel resources;select for each unit of control information a unique combination of at least one of the sub-channels and a modulation, in which the control information is at least one of acknowledge, negative acknowledge, and discontinuous transmission signaling; andsend the control information according to the respectively selected combinations, in the assigned uplink control channel resources corresponding to at least one of physical uplink control channel format 1a and 1b resources.
