Abstract
A wireless device receives a configuration of a physical uplink control channel (PUCCH) group. The PUCCH group comprises a PUCCH secondary cell with a secondary PUCCH and a secondary cell. A command indicating deactivation of the PUCCH secondary cell is received in a first subframe. In response to the deactivation of the PUCCH secondary cell, transmission of channel state information for the secondary cell in a second subframe that is eight subframes after the first subframe is stopped. Thee stopping does not occur before the second subframe.
Claims18
A method comprising:
- receiving, by a wireless device, a configuration of a physical uplink control channel (PUCCH) group comprising:
- a first secondary cell with a secondary PUCCH;
- and
- a second secondary cell;
- receiving, in a first subframe, a media access control (MAC) command comprising a bitmap indicating deactivation of the first secondary cell;
- and
- stopping, in response to the deactivation of the first secondary cell, transmission of channel state information for the second secondary cell in a second subframe that is eight subframes after the first subframe, wherein the stopping does not occur before the second subframe.
