METHOD AND APPARATUS FOR PRESERVING PHYSICAL UPLINK CONTROL CHANNEL RESOURCES

摘要

A network configuration and process are disclosed in which a user equipment preserves its physical uplink control channel resources (PUCCH) in connected mode when so instructed by the network upon expiration of a time alignment timer. Upon re-initiation of network messaging the network passes information to the user equipment during random access signalling to re-use the physical uplink control channel resources.
