摘要： Aspects of the present invention relate to the scheduling of resources in a telecommunication system that includes a mobile terminal and base station. In one embodiment, the mobile terminal sends an initial scheduling request to a base station. Subsequently, the mobile terminal does not transmit a scheduling request to the base station unless and until a scheduling request triggering event is detected.

摘要： Methods for efficiently controlling the retransmission of data units in a wireless telecommunication system, wherein multiple complementary feedback mechanisms are used to control retransmission. A receiver attempts to decode each received data unit. If a data unit is successfully decoded, the receiver transmits positive feedback to the transmitter; if a data unit is not successfully decoded, the receiver transmits negative feedback to the transmitter. In all cases, the transmitter employs at least first and second feedback mechanisms for transmitting the positive and negative feedback. In an exemplary embodiment, acknowledgement (ACK) and non-acknowledgement (NACK) messages are sent in response to the receipt of each data unit on a first unreliable channel and Status Messages identifying sequence numbers of particular data units are periodically transmitted on a second reliable channel; the receiver preferably removes data units from its transmit window only upon receipt of a Status Message indicating successful decode.

摘要： A base station of a mobile communication network supports continuity of a Multimedia Broadcast Multicast Service, MBMS, for a terminal. The base station receives, from the terminal, an information element informing the base station of a combination of bands, which the terminal supports for carrier aggregation. The terminal supports MBMS reception on any carrier configurable as a serving cell for the terminal according to the information element. The base station derives, from the received information element, MBMS reception capabilities of the terminal. The base station determines a number of carriers, which are configurable by the base station as serving cell of the terminal, such that the terminal is enabled to receive at least one MBMS.

摘要： The present invention relates to a transmission of information in a wireless communication network between a radio access node and a relay node, wherein, according to a new ground rule, for each allocated downlink subframe for a down link transmission from the access node to the relay node, an uplink transmission subframe for an uplink transmission is allocated four transmission time intervals later. A downlink subframe is only allocated when a further subframe of the same transmission time interval for a transmission from the relay node to the user equipment is a subframe of a type that indicates to a user equipment that no data are received beyond a control region of the subframe.

摘要： The present invention relates to a method and to a transceiver (400) for detecting HARQ transmission failure in a telecommunications system. The transceiver (400) is arranged to execute a HARQ process which is used to generate a transmission of data units to e.g. a eNodeB. The transceiver is also arranged to determine when a maximum number of transmission attempts is reached and when this occurs to flush a HARQ buffer associated with the HARQ process and to detect that a HARQ transmission failure has occurred when the last HARQ feedback received for the current HARQ process is not a HARQ ACK.

摘要： Control of a data packet buffer in a communication system and a data packet queue in a transmission link are shown. The queue stores a plurality of received data packets that are intended for transmission over a wireless interface. Selected packets are discarded from the queue without the selected packets having been transmitted. A packet is selected for discarding depending on at least the length of time the packet has been stored in the queue. The discarding of a selected packet is effectuated on condition that at least a predetermined time period has elapsed since a previous discarding of a packet has taken place. Such a solution is advantageous in that, for varying transmission bandwidth conditions in the transmission link, it is possible to achieve good link utilization and throughput, while at the same time enabling a low end-to-end delay for packets transmitted in the link.
