Uplink Control Information Transmission in a Wireless Network
A physical uplink control channel (PUCCH) may comprise a plurality of sets of PUCCH resource blocks overlapping in time. A plurality of channel state information (CSI) reports may be used for transmission via the PUCCH resource blocks. Transmission of at least one CSI report for transmission may use PUCCH resource blocks based on a size of the CSI report and size of the sets of PUCCH resource blocks.
1 . A method comprising:
receiving, by a wireless device and from a base station, configuration of a physical uplink control channel (PUCCH) for the wireless device, wherein the PUCCH comprises a first set of PUCCH resource blocks that overlaps in time with a second set of PUCCH resource blocks; and
transmitting one or more CSI reports via the second set of PUCCH resource blocks, wherein use of the second set of PUCCH resource blocks is based on:
a comparison comprising a size of the one or more CSI reports and a size of the first set of PUCCH resource blocks; and
a preference for the first set of PUCCH resource blocks based on the first set of PUCCH resource blocks comprising a smaller size than the second set of PUCCH resource blocks.
2 . The method of claim 1 , further comprising transmitting, by the wireless device via the first set of PUCCH resource blocks, at least one other CSI report, wherein use of the first set of PUCCH resource blocks is based on the first set of PUCCH resource blocks having a smaller size than the second set of PUCCH resource blocks.
3 . The method of claim 1 , further comprising selecting the one or more CSI reports according to at least a CSI report priority that is based, at least in part, on a CSI process identification (ID).
4 . The method of claim 1 , further comprising determining a plurality of CSI reports, for transmission, based on signals received via a plurality of cells that are configured for the wireless device to transmit CSI reports.
5 . The method of claim 1 , further comprising determining a plurality of CSI reports, for transmission, based on signals received via a plurality of cells that are grouped into a plurality of PUCCH groups comprising:
a primary PUCCH group comprising a primary cell with a primary PUCCH transmitted to the base station; and
a secondary PUCCH group comprising a secondary cell with a secondary PUCCH transmitted to the base station.
6 . The method of claim 1 , wherein the one or more CSI reports comprises a plurality of CSI reports, wherein use of the second set of PUCCH resource blocks is based on a size of the plurality of CSI reports, and wherein the transmitting comprises transmitting the plurality of CSI reports.
7 . A method comprising
transmitting, by a base station and to a wireless device, configuration of a physical uplink control channel (PUCCH) for the wireless device, wherein the PUCCH comprises a first set of PUCCH resource blocks that overlaps in time with a second set of PUCCH resource blocks; and
receiving one or more CSI reports via the second set of PUCCH resource blocks, wherein use of the second set of PUCCH resource blocks is based on:
a comparison comprising a size of the one or more CSI reports and a size of the first set of PUCCH resource blocks; and
a preference for the first set of PUCCH resource blocks based on the first set of PUCCH resource blocks comprising a smaller size than the second set of PUCCH resource blocks.
8 . The method of claim 7 , further comprising receiving, from the wireless device via the first set of PUCCH resource blocks, at least one other CSI report, wherein use of the first set of PUCCH resource blocks is based on the first set of PUCCH resource blocks having a smaller size than the second set of PUCCH resource blocks.
9 . The method of claim 7 , wherein the one or more CSI reports were selected according to at least a CSI report priority that is based, at least in part, on a CSI process identification (ID).
10 . The method of claim 7 , wherein CSI reports are determined for transmission based on signals received via a plurality of cells that are grouped into a plurality of PUCCH groups comprising:
a primary PUCCH group comprising a primary cell with a primary PUCCH transmitted to the base station; and
a secondary PUCCH group comprising a secondary cell with a secondary PUCCH transmitted to the base station.
11 . The method of claim 7 , wherein the one or more CSI reports comprises a plurality of CSI reports, wherein use of the second set of PUCCH resource blocks is based on a size of the plurality of CSI reports, and wherein the receiving comprises receiving the plurality of CSI reports.
12 . A base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, configure the base station to:
transmit, to a wireless device, configuration of a physical uplink control channel (PUCCH) for the wireless device, wherein the PUCCH comprises a first set of PUCCH resource blocks that overlaps in time with a second set of PUCCH resource blocks; and
receive one or more CSI reports via the second set of PUCCH resource blocks, wherein use of the second set of PUCCH resource blocks is based on:
a comparison comprising a size of the one or more CSI reports and a size of the first set of PUCCH resource blocks; and
a preference for the first set of PUCCH resource blocks based on the first set of PUCCH resource blocks comprising a smaller size than the second set of PUCCH resource blocks.
13 . The base station of claim 12 , wherein the instructions, when executed by the one or more processors, further configure the base station to receive, from the wireless device via the first set of PUCCH resource blocks, at least one other CSI report, wherein use of the first set of PUCCH resource blocks is based on the first set of PUCCH resource blocks having a smaller size than the second set of PUCCH resource blocks.
14 . The base station of claim 12 , wherein the one or more CSI reports were selected according to at least a CSI report priority that is based, at least in part, on a CSI process identification (ID).
15 . The base station of claim 12 , wherein CSI reports are determined for transmission based on signals received via a plurality of cells that are grouped into a plurality of PUCCH groups comprising:
a primary PUCCH group comprising a primary cell with a primary PUCCH transmitted to the base station; and
a secondary PUCCH group comprising a secondary cell with a secondary PUCCH transmitted to the base station.
16 . The base station of claim 12 , wherein the one or more CSI reports comprises a plurality of CSI reports, wherein use of the second set of PUCCH resources is based on a size of the plurality of CSI reports, and wherein the receiving comprises receiving the plurality of CSI reports.
