Updating secondary cell configuration in a wireless network
View Patent ↗A plurality of cells are grouped into a plurality of physical uplink control channel (PUCCH) groups comprising a primary PUCCH group and a secondary PUCCH group comprising a first plurality of secondary cells. The first plurality of secondary cells comprises a PUCCH secondary cell. A wireless device receives a second message comprising one or more parameters indicating a release of the PUCCH secondary cell. The wireless device releases each of the first plurality of secondary cells in the secondary PUCCH group.
1. A method comprising:
receiving, by a wireless device from a base station, at least one message comprising configuration parameters of a plurality of cells, the plurality of cells grouped into a plurality of physical uplink control channel (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 first plurality of secondary cells in the plurality of cells, the first plurality of secondary cells comprising a PUCCH secondary cell with a secondary PUCCH transmitted to the base station;
receiving a second message comprising one or more parameters indicating a release of fewer than all of the first plurality of secondary cells, wherein the fewer than all of the first plurality of secondary cells comprises the PUCCH secondary cell; and
releasing each of the first plurality of secondary cells in the secondary PUCCH group in response to the one or more parameters indicating the release of the PUCCH secondary cell.
2. The method of claim 1 , wherein the configuration parameters comprise:
a plurality of common parameters; and
a plurality of dedicated parameters.
3. The method of claim 1 , further comprising the base station detecting a radio link issue with the PUCCH secondary cell employing at least one of the following:
detecting a loss of PUCCH secondary cell signals;
detecting a loss of synchronization with the PUCCH secondary cell signals; and
measuring high error rates on the PUCCH secondary cell.
4. The method of claim 1 , further comprising the base station detecting a radio link issue with the PUCCH secondary cell employing at least one of the following:
measuring high interference on the PUCCH secondary cell;
receiving a channel quality indicator (CQI) feedback indicating poor signal quality on the PUCCH secondary cell; and
receiving measurement reports indicating poor signal quality on the PUCCH secondary cell.
5. The method of claim 1 , further comprising transmitting a second message indicating a radio link issue with the PUCCH secondary cell.
6. The method of claim 1 , wherein at least one message comprises a cell index of the PUCCH secondary cell.
7. The method of claim 1 , further comprising transmitting channel state information on the secondary PUCCH.
8. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed, cause the wireless device to:
receive, from a base station, at least one message comprising configuration parameters of a plurality of cells, the plurality of cells grouped into a plurality of physical uplink control channel (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 first plurality of secondary cells in the plurality of cells, the first plurality of secondary cells comprising a PUCCH secondary cell with a secondary PUCCH transmitted to the base station;
receive a second message comprising one or more parameters indicating a release of fewer than all of the first plurality of secondary cells, wherein the fewer than all of the first plurality of secondary cells comprises the PUCCH secondary cell; and
release each of the first plurality of secondary cells in the secondary PUCCH group in response to the one or more parameters indicating the release of the PUCCH secondary cell.
9. The wireless device of claim 8 , wherein the configuration parameters comprise:
a plurality of common parameters; and
a plurality of dedicated parameters.
10. The wireless device of claim 8 , wherein the base station is configured to detect a radio link issue with the PUCCH secondary cell employing at least one of the following:
a detection of a loss of PUCCH secondary cell signals;
a detection of a loss of synchronization with the PUCCH secondary cell signals; and
a measurement of high error rates on the PUCCH secondary cell.
11. The wireless device of claim 8 , wherein the base station is configured to detect a radio link issue with the PUCCH secondary cell employing at least one of the following:
a reception of a channel quality indicator (CQI) feedback indicating poor signal quality on the PUCCH secondary cell; and
a reception of measurement reports indicating poor signal quality on the PUCCH secondary cell.
12. The wireless device of claim 8 , wherein the instructions, when executed, further cause the wireless device to transmit a second message indicating a radio link issue with the PUCCH secondary cell.
13. The wireless device of claim 8 , wherein the at least one message comprises a cell index of the PUCCH secondary cell.
14. The wireless device of claim 8 , wherein the instructions, when executed, further cause the wireless device to transmit channel state information on the secondary PUCCH.
