Radio Resource Control Mechanism in a Wireless Device and Wireless Network

摘要

Cells are grouped into a plurality of physical uplink control channel (PUCCH) groups comprising a primary PUCCH group and a secondary PUCCH group. A base station detects a radio link issue with a PUCCH secondary cell while one or more other cells in the secondary PUCCH group have acceptable radio link quality. The base station transmits at least one second message configured to release at least one of the one or more other cells in the secondary PUCCH group.

主权项

1. A method comprising:
transmitting, by a base station to a wireless device, at least one first message comprising configuration parameters of a plurality of cells, wherein the plurality of cells are grouped into a plurality of physical uplink control channel (PUCCH) groups comprising:
a primary PUCCH group comprising a primary cell with a primary PUCCH received by the base station; anda secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH received by the base station; detecting a radio link issue with the PUCCH secondary cell while one or more other cells in the secondary PUCCH group have acceptable radio link quality; and transmitting at least one second message configured to release at least one of the one or more other cells in the secondary PUCCH group.
