摘要:
A method in a wireless communication system for reporting buffer information includes selecting a format for a buffer report based on a number of radio bearer groups, k, for which data is available for transmission by a user equipment. The buffer report indicates a respective buffer fill level for one or more radio bearer groups associated with the user equipment. The method also include encoding a buffer fill level for one or more radio bearer groups in a buffer report in accordance with the selected format and transmitting the buffer report.

The invention relates to a technique for uplink data transmissions in, e.g., mobile networks. A method embodiment for performing the technique in a transmitter (122) comprises the steps of allocating, for a first transmission (T1′) as the transmission power for an uplink control channel (UCOCH), the smaller of an available transmission power and a desired transmission power for the uplink control channel; and allocating, for at least one subsequent transmission (T2′) triggered by a feedback indication (128), zero transmission power to the uplink control channel (UCOCH).

Methods and apparatus for processing error control messages, such as RLC ARQ control messages, are disclosed. An exemplary method comprises signaling a medium access controller (MAC) that link resources are needed for transmitting data, receiving an indication from the MAC that link resources for transmitting the data are scheduled, and generating an error control message after receiving said indication, based on a current error control status. The error control message is then forwarded to the MAC for transmission. Because the generation of an error control message is delayed until resources for its transmission are scheduled, the queuing of stale control messages is avoided.

The present invention relates to a UE, base station network node and methods thereof in a cellular mobile communication system. One method concerns handover from a first radio base station to a second radio base station wherein, it comprises the steps receiving a notification from the first radio base station that currently serves said UE, said notification indicating the last packet to be transmitted to this user equipment from said first radio base station on a first connection; and informing the second radio base station by a request to commence transmission from this second radio base station when the notified last packet is received at the UE.

摘要:
According to the teachings presented herein, a base station implements active queue management (AQM) for uplink transmissions from user equipment (UE), such as a mobile terminal. The base station, e.g., an eNodeB in a Long Term Evolution (LTE) network, uses buffer status reports, for example, to estimate packet delays for packets in the UE's uplink transmit buffer. In one embodiment, a (base station) method of AQM for the uplink includes estimating at least one of a transmit buffer size and a transmit buffer queuing delay for a UE, and selectively dropping or congestion-marking packets received at the base station from the UE. The selective dropping or marking is based on the estimated transmit buffer size and/or the estimated transmit buffer queuing delay.

A method and apparatus for signaling scheduling information in a spatial multiplexing wireless communications system, as well as corresponding methods and apparatus for processing such signaling information, are disclosed. Signaling scheduling information includes scheduling first and second transport blocks for simultaneous transmission during a first transmission interval on first and second data substreams, respectively, and assigning a single re-transmission process identifier for the first transmission interval and transmitting first scheduling information for the first transmission interval. The first scheduling information includes the re-transmission process identifier and first disambiguation data. Additionally, at least one of the first and second transport blocks is scheduled for re-transmission during a second transmission interval. Second scheduling information for the second transmission interval is also transmitted; the second scheduling information including the re-transmission process identifier and second disambiguation data.

A method for configuring a connection between first and second peer entities in a wireless telecommunications network comprises sending a hash value between the first and second peer entities, the hash value being a compact representation of information relating to a connection configuration procedure between the first and second peer entities.

The present invention relates to a user equipment, UE, wirelessly connectable to a cellular mobile communication network adapted to perform uplink cell change of the UE from the first radio base station to a second radio base station. The UE comprises means for controlling the HARQ retransmissions and means for determining the time point for performing the cell change based on the controlled ongoing HARQ retransmissions of outstanding data.

The present invention provides a stall avoidance mechanism that may be used alone or in conjunction with an ambiguity avoidance mechanism in an ARQ protocol. Both mechanisms decrease data delays and increase data throughput rates. Stall avoidance is accomplished by determining whether a stall condition exists with respect to receiving a missing data unit. In one example, only a single timer is needed to avoid stalls. Retransmission ambiguities may be avoided using a retransmission window in the transmitter and/or a receive window in the receiver. Although each mechanism may be used independently of the other, a preferred example embodiment uses a stall avoidance timer, a retransmission window in the transmitter, and a receive window in the receiver.
