摘要:
Method and arrangement in a first node for requesting a status report from a second node. The first node and the second node are both comprised within a wireless communication network. The status report comprises positive and/or negative acknowledgement of data sent from the first node, to be received by the second node. The first node comprises a first counter configured to count the number of transmitted Protocol Data Units, PDUs, and a second counter configured to count the number of transmitted data bytes. The method and arrangements comprises initializing the first and the second counter to zero, transmitting data to be received by the second node, comparing the value of the first and the second counters with a first threshold limit value and a second threshold limit value and requesting a status report from the second node if any of the threshold limit values is reached or exceeded.

A Level-1 (L1) signaling flag is mapped to unused (invalid) bit sequences in Part 1 of the HS-SCCH—that is, Part 1 bit encodings that are not defined in the UTRAN specifications—and a corresponding L1 command is encoded in Part 2. This allows UE to detect early that the HS-SCCH is pure L1 signaling, and the UE may avoid wasting power by not processing an accompanying HS-PDSCH. Alternatively, in CPC HS-SCCH-less mode, the UE may blind decode the HS PDSCH. In one embodiment, a general DRX mode is defined and controlled via L1 signaling. In one embodiment, a UE acknowledgement improves the L1 signaling accuracy. In one embodiment, a L1 signal and UE acknowledgement protocol are utilized to “ping” a UE.

The present invention relates to a method for use in a user equipment (10), and relates to a user equipment (10) for enabling a serving base station (40) to estimate interference contribution in a network when scheduling resources for the use equipment. According to the method, the user equipment determines an amount of resources required to send data and the user equipment sends a report to it serving base station when the required amount of resources is greater than a threshold value. In the report, measurements performed by the user equipment are included. The report will assist the serving base station with its estimation of the degree of interference user equipments generates in the network, and hence the power and resources to assign.
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.

Methods and arrangements in a base station and a User Equipment are provided. The methods and arrangements relates to the scenario when the UE is handed over from a source base station to a target base station in a handover scenario, and wherein the target base station may not support functionalities which the source base station and the UE support. The method in the UE comprises receiving (501) a configuration message from the target base station via the source base station, configuring (502) the UE based on the received configuration message from the target base station by searching (503) for a second field in an information element of the received configuration message. The presence/non-presence or a value of the second field is indicative of how to manage a configured first functionality associated with an optional first field, wherein the configured first functionality may not be supported by the target base station.

The present invention relates to wireless communication systems, and more particularly to a method and an apparatus for periodically reporting the buffer status in a wireless communication system. Methods and arrangements for an improved buffer status reporting taking the type of radio bearer configuration into account is provided. This is achieved according to an embodiment of the present invention by taking the type of radio bearer configuration into account when determining the content of the buffer status report sent by the UE to the eNodeB.
摘要:
A base station indicates to mobile stations as to whether specific offsets apply for use when measuring a signal strength of base stations in neighboring cells. Additionally, if the neighboring cells do use offsets, the present invention may indicate as to whether the neighboring cell offsets are the same as the current serving cell offset.
摘要:
A node (22) of a telecommunications network (2) receives, over a transmission chain (24) subject to packet jitter, packets of a connection involving a client device (26). The node (22) comprises a packet buffer (38) configured to store the packets received over the transmission chain prior to transmission of the packets to the client device (26). The node (22) further comprises a client-conscious scheduler (40) which is configured to schedule the transmission of the packets from the packet buffer (38) over a channel (32) to the client device (26) in accordance with a timing consideration of the client device (26). In an example embodiment, the timing consideration of the client device (26) which is taken into account by the scheduler (40) is avoidance of drain of a playout buffer of the client device.
