Common control deactivation in carrier aggregation

摘要

There are provided measures for common control deactivation in carrier aggregation, said measures exemplarily including a configuration of a secondary carrier for carrier aggregation with a primary carrier of a terminal, including a deactivation of a common control for the secondary carrier, an indication of the deactivation of the common control for the secondary carrier via the primary carrier, and a signaling of control information, substituting control information of the deactivated common control, for facilitating selection of or operation on the secondary carrier without the deactivated common control via the primary carrier from a base station to the terminal. Said measures may exemplarily be applied for common control deactivation in carrier aggregation in heterogeneous network environments based on LTE, LTE-Advanced, HSPA and/or UMTS radio access systems.

主权项

1. A method comprising:
configuring, by a network entity, a secondary carrier for carrier aggregation with a primary carrier of a terminal, including deactivating a physical common channel for the secondary carrier; transmitting, by the network entity, an indication of the deactivation of the physical common channel for the secondary carrier via the primary carrier to the terminal; and transmitting, by the network entity, a signaling of control information that is substituting other control information of the deactivated physical common channel, the control information facilitating selection of the secondary carrier and enabling the terminal to access and monitor a common reference signal of the secondary carrier without the deactivated physical common channel via the primary carrier to the terminal, wherein the control information comprises information for at least two of synchronization with the secondary carrier, radio resource management related measurements on the secondary carrier, demodulation of a shared data channel of the secondary carrier, and radio link failure recovery of the secondary carrier.
