20120236782 | QUALITY OF SERVICE CONTROL IN A RELAY - A method in a communications system in which a plurality of user equipments are transmitting data to a donor node via a relay node, the plurality of user equipments each storing the data in its own UE buffer prior to transmission to the relay node, the relay node storing the data received from the plurality of user equipments in a relay buffer prior to transmission to the donor node. The method comprises at the relay node, sending a relay buffer status report from the relay node to the donor node when a buffered data value passes a threshold value. The buffered data value representing either data stored in the UE buffers or data stored in the relay buffer. | 09-20-2012 |
20120243461 | RELAY HANDOVER CONTROL - A method is provided in handover of a user equipment in a communications system from communicating with a donor node via a relay node, to communicating with a target node, the donor node being operable to transmit downlink data to the relay node in a series of sequentially marked donor packets, the relay node being operable to then transmit the downlink data to the user equipment in a series of sequentially marked relay packets. The method includes receiving a handover request at the donor node and, upon receipt, beginning buffering of the donor packets in a temporary buffer at the donor node, transmitting a status message from the relay node to the donor node indicating a first of the relay packets not received by the user equipment, transmitting an update message from the donor node to the relay node indicating the first donor packet buffered in the temporary buffer. | 09-27-2012 |
20120243462 | TRANSMISSION IN A COMMUNICATION SYSTEM USING RELAY NODES - The application relates to a transmission method in a communication system comprising a base station, a relay node and a plurality of UEs, the method comprising: when a new user data stream is established between a UE and the relay node, sending data stream characteristics including quality of service requirements, a channel identification and a UE identification for the user data stream to the base station; for transmission between the relay node and the base station, grouping the user data stream into one of a plurality of groups of multiplexed user data streams, each of which groups is defined by quality of service requirements; wherein the user data stream can be distinguished within its group on receipt using multiplexing information held within the group in conjunction with the data stream characteristics. | 09-27-2012 |
