摘要： A radio access network comprises a donor base station node (29) and a relay base station node (20). The relay base station node (29) participates in communications across a first radio interface with a wireless terminal (30) and also participates in communications over a backhaul link across a second radio interface, the second radio interface reusing at least some functionality of the first interface. The donor base station node (28) configures a subframe configuration pattern. The subframe configuration pattern is arranged to specify which subframe(s) of a frame structure may be utilized for the backhaul link. As a result of subframe configuration, a HARQ process state in a HARQ process at one of the base station nodes is known by the other base station node by any of several operational modes.

摘要： The mobile station described herein comprises a transmission buffer, a receiver, a transmitter, and a controller. The controller triggers a scheduling request and buffer status report when data enters the transmission buffer. When the receiver receives a contention-based scheduling grant allocating contention-based uplink resources, the transmitter transmits one or more data packets retrieved from the transmission buffer along with the buffer status report on the contention-based resources to the network station. If one or more data packets remain in the transmission buffer after transmission of the buffer status report on the contention-based resources, the controller maintains the pending status of the buffer status report and the corresponding scheduling request.

摘要： Fields such as sequence numbers and length indicators of protocol layers are extended in extended headers so as to be backwards compatible with corresponding legacy headers. The existing fields of the legacy headers are not directly extended. Instead, existing fields are logically concatenated with other fields of the extended header. Whether the extended fields or legacy fields will be used can be determined dynamically based on current transport block size or semi-statically by higher layers.

摘要： The present disclosure relates to methods and devices for filtering uplink data in a radio communication system. The present disclosure more specifically relates to a method performed in a radio device 100. The method comprises receiving, over a radio interface, a message comprising at least one barring parameter associated with a characteristic of a logical bearer 30 between the radio device and a core network 300. The method also comprises determining that an uplink data packet is associated with the characteristic of the logical bearer. The method also comprises determining, based at least on the barring parameter, whether access for transmitting the UL data packet 10 over the radio interface is allowed.

摘要： In one or more embodiments, the present invention provides a method and apparatus for "early" triggering of a BSR in a relay node ( 16). Doing so is advantageous, for example, in reducing the overall time between a UE's transmission of data to a relay node ( 16) on an access link (22) and the corresponding transmission of that data from the relay node (16) to a donor base station (20) on a backhaul link (24). Of course, that example is non-limiting. More broadly, in at least one embodiment, the present invention provides for triggering a BSR in the relay node (16) right after learning that there is at least one UE (12) connected to the relay node ( 16) that wants to transmit UL data. Further, one or more embodiments provide a simple method and apparatus for using a relay node BSR to inform a donor base station (20) about the scheduled status of UEs supported by the relay node (16).

摘要： A system, method and node of downlinking transmissions to an unsynchronized UE in a telecommunications network. The method begins by a node in the network requesting synchronization of the UE with the network. A first transmission of data is sent from the node to the UE prior to synchronization of the UE. The UE then synchronizes with the network by the UE performing a Random Access procedure with the node, thereby triggering a time alignment command from the node to the UE to synchronize the UE with the network. A second transmission of data is then sent from the node to the UE after the UE is synchronized. A response feedback message is sent to the node from the UE. The message is a cumulative feedback message of the first transmission of data and the second transmission of data. Thus, data may be transmitted prior to synchronization of the UE.

摘要： method and an arrangement (800) in a radio network node (140) for sharing of a first Cell Radio Network Temporary Identifier, referred to as “C-RNTI” between at least a first and a second communication device (110, 120) are provided. The radio network node (140) receives a first random access preamble from the first communication device (110). Furthermore, the radio network node (140) associates the first C-RNTI to the first communication device (110), in response to the first random access preamble. The radio network node (140) receives a second random access preamble from the second communication device (120). Moreover, the radio network node (140) associates the first C-RNTI to the second communication device (120), in response to the second random access preamble, while the association of the first C-RNTI to the first communication device (110) is maintained. A method and an arrangement (900) in a first communication device (110) for enabling sharing of a first Cell Radio Network Temporary Identifier between at least the first communication device (110) and a second communication device (120) are provided.

摘要： A method implemented at a user equipment (UE) may include receiving a grant from a base station permitting the user equipment to transmit data to the base station and transmitting data to the base station, where the data includes a buffer status report (BSR) that indicates an amount of data in a buffer of the UE. The method may further include starting or restarting a discontinuous reception (DRX) timer when the data including the BSR is transmitted to the base station. The method may additionally include monitoring (730) a control channel during a duration of the DRX timer. In another implementation, a method may include receiving a feedback message in response to the data transmission including the BSR, and starting or restarting the discontinuous reception (DRX) timer when the feedback message is received. The feedback message may include an acknowledgement (ACK) or a negative acknowledgement (NACK). In a further implementation, a method may include starting a process specific hybrid automatic repeat request (HARQ) round trip time (RTT) timer upon transmission of the data including the BSR, starting a grant timer when the HARQ RTT timer expires, and monitoring the control channel during a duration of the grant timer.
