First Claim
Patent Images
1. One or more non-transitory computer readable media having instructions that, when executed, cause a communication device to:
- identify uplink control information (UCI) bits, which include channel state information (CSI) bits of a CSI bit stream and acknowledgement/negative acknowledgement (ACK/NACK) bits of a hybrid automatic repeat request-acknowledgement (HARQ-ACK) bit stream, to be transmitted in a physical uplink control channel (PUCCH) of a subframe, the CSI bits associated with a CSI report for a plurality of cells;
identify whether a number of the UCI bits is greater than a threshold;
if the number is not greater than the threshold, transmit the UCI bits with the CSI bits appended to the ACK/NACK bits; and
if the number is greater than the threshold;
identify one or more first cells of the plurality of cells, the one or more first cells having one or more cell index values, respectively, that are lower than one or more cell index values of one or more second cells of the plurality of cells, respectively;
select a subset of the CSI bits based on a result of the identification of the one or more first cells, wherein the CSI bits include first CSI bits corresponding to the one or more first cells and second CSI bits corresponding to the one or more second cells, and wherein the subset of the CSI bits includes all the first CSI bits and only some of the second CSI bits; and
transmit a portion of the UCI bits with the subset of the CSI bits appended to the ACK/NACK bits.

15. An apparatus to be included in user equipment (UE), the apparatus comprising:
-
first circuitry to provide uplink control information (UCI) bits, which include channel state information (CSI) bits of a CSI bit stream and acknowledgement/negative acknowledgement (ACK/NACK) bits of a HARQ-ACK bit stream, to be transmitted in a physical uplink control channel (PUCCH) of a subframe; and second transmit circuitry coupled to the first circuitry, the second transmit circuitry to; identify whether a number of the UCI bits is greater than a threshold; if the number is not greater than the threshold, transmit the UCI bits with the CSI bits appended to the ACK/NACK bits to an evolved node B (eNB); and if the number is greater than the threshold, select a subset of the CSI bits and transmit a portion of the UCI bits with the subset of the CSI bits appended to the ACK/NACK bits to the eNB, wherein if the CSI bits are associated with a CSI report for a plurality of cells, select the subset of the CSI bits further includes; identify one or more first cells of the plurality of cells, the one or more first cells having one or more cell index values, respectively, that are lower than one or more cell index values of one or more second cells of the plurality of cells, respectively; and select the subset of the CSI bits based on a result of an identification of the one or more first cells, wherein the CSI bits include first CSI bits corresponding to the one or more first cells and second CSI bits corresponding to the one or more second cells, and wherein the subset of the CSI bits includes all the first CSI bits and only some of the second CSI bits. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
