TELECOMMUNICATIONS APPARATUS AND METHODS

摘要

A wireless telecommunication system that comprises a base station and a terminal device communicating over a radio interface. The radio interface supports a downlink control channel for conveying control messages from the base station to the terminal device and a downlink data channel (e.g. a physical downlink shared channel) for conveying higher-layer messages from the base station to the terminal device. The control messages convey information on resource allocations for the higher-layer messages on the downlink data channel. The terminal device is configured to receive a control message from the base station conveying an indication of allocated transmission resources on the downlink data channel and determine a validity period for the control-plane message. During the validity period for the control message the terminal device is configured to receive a plurality of different higher-layer messages from the base station on the downlink data channel using the allocated transmission resources.

1: A method of operating a terminal device communicating with a base station in a telecommunications system over a radio interface supporting a downlink control channel for conveying control messages from the base station to the terminal device and a downlink data channel for conveying other messages from the base station to the terminal device, wherein the control messages convey information on resource allocations for the other messages on the downlink data channel, and wherein the method comprises receiving a control message from the base station conveying an indication of allocated transmission resources on the downlink data channel, determining a validity period for the control message, and receiving a plurality of other messages from the base station on the downlink data channel using the allocated transmission resources within the validity period for the control message.
