摘要： In a wireless communication network where base stations receive protocol data units (PDUs) from mobile stations for decompression and deciphering for ordered, sequential transfer as service data units (SDUs) to an associated core network, the teachings presented herein provide a method of supporting seamless handover of a mobile station from a source base station to a target base station. By way of example, the teachings herein apply to a network based on the E-UTRA specifications, as promulgated by the 3GPP. However, that example is non-limiting, as the teachings herein apply to any network that employs in-sequence data delivery and duplicate data detection at handover. Broadly, the source base station forwards out-of-sequence SDUs and corresponding sequence number information to the target base station in support of seamless handover, and the target base station uses that information to request retransmissions as needed for packet reordering.

摘要： A method for sending buffer status information includes checking if a quality of service (QoS) parameter is defined for a first logical channel and at least one condition of the set of predetermined conditions associated with a logical channel group is fulfilled. If the QoS parameter is defined and at least one condition of the set is fulfilled, the method includes setting a number of bits in a media access control header according to a first semantic. The bits carry buffer status information, and the first semantic—is based on the QoS parameter of the first logical channel. Otherwise, the method includes setting the number of bits carrying the buffer status information according to a second semantic that is based on an amount of data available for transmission across the logical channel group.

摘要： User equipment in a wireless communication system monitors scheduling information and locally detects a change in link data rate of the uplink channel based on the monitored scheduling information. In this way, a change in link data rate can be detected directly without significant delay. This direct or early detection of a rate change is then combined with an appropriate system reaction. The information of the detected change in link data rate is preferably utilized for adapting the application data rate of an IP application running in the user equipment. As an alternative, or as a complement, data packets are classified based on relative importance and selected for transfer of information over the uplink channel based on the classification of data packets and in dependence on the detected change in link data rate.

摘要： Methods and apparatus for producing a compressed buffer status report (400) for use in a wireless network are disclosed. In several of the disclosed embodiments, a wireless terminal (160) forms a compressed buffer status report (400) that includes a field (410) of one or more bits that indicate an overall status corresponding to all or substantially all of the uplink data buffers for the wireless terminal (160), along with one or more fields (420) that indicate buffer status for specific corresponding radio bearers or groups of radio bearers. Accordingly, a small buffer report (410) may be sent in-band with the uplink data transmission, such as in headers (810) of one or more MAC packet data units (800), to convey information about the status of the wireless terminal's buffers, both for all the buffers (i.e., collectively), and for each of several high-priority radio bearers or groups of radio bearers.

摘要： Techniques for a mobile station to signal a request for a reduction in data transmission rate to a base station are disclosed. An example method for facilitating flow control in a wireless communication system includes monitoring resource use associated with a mobile station and, based upon the resource use, setting a congestion indicator in a header of at least one uplink traffic data packet. The uplink traffic data packet is then sent to a wireless base station, which detects the congestion indicator. In some embodiments, ECN bits in an IP header of the uplink traffic data packet are set. In other embodiments, ECN bits in an IP header of a downlink traffic data packet are set, to trigger the generation of a TCP header that indicates congestion in subsequent uplink packets.
