TELECOMMUNICATIONS APPARATUS AND METHODS

摘要

Methods and apparatus for transmitting data to terminal devices in a wireless telecommunications system. The data may be user-plane data associated with a repeating Multimedia Broadcast/Multicast Services (MBMS) session to be transmitted using MBMS over a Single Frequency Network (MBSFN) in a network including at least one relay node supported by a donor base station. The scheme includes delivering the data from the base station to the relay node in advance of a scheduled transmission to terminal devices at a first time, and transmitting the data from the relay node to a terminal device at the first time. The relay node is further configured to store the data in a cache. The relay node may then retrieve the data from the cache in advance of a scheduled transmission to terminal devices at a second time, and transmit the retrieved data to a terminal device at the second time.

主权项

1. A method of operating a base station to control the transmission of data to terminal devices in a wireless telecommunications system by a relay node for the base station, the method comprising:
transmitting the data to the relay node for transmission by the relay node to a terminal device at a first time; conveying an indication to the relay node to indicate the relay node should attempt to store the data in a cache at the relay node; and subsequently conveying an indication to the relay node to indicate the relay node should retrieve the data from the cache and transmit the data to a terminal device at a second time.
