Uplink resynchronization for use in communication systems

摘要

A method and apparatus for reusing an uplink control channel configuration associated with an uplink control channel, the method comprising the steps of, at a user agent, receiving an uplink control channel resource configuration assigned by an access device, transmitting to the access device using the control channel resources associated with the received uplink control channel resource configuration and, after a time alignment timer expires, retaining the uplink control channel resource configuration.

主权项

1. An access device comprising:
a processor; and a memory for storing instructions executable by the processor; wherein the processor is programmed to:
send a Physical Uplink Control Channel (PUCCH) resource configuration to a wireless device, the PUCCH resource configuration including an indication of a PUCCH resource;transmit one or more time advance commands to the wireless device to control a time alignment timer in the wireless device;receive uplink transmissions from the wireless device over the PUCCH resource;receive an uplink transmission request after the time alignment timer has expired; andsend an indication that the PUCCH resource configuration is still available.
