Abstract: Underlay network node and macro base station and methods therein for enabling avoidance of interference in a cell extension area associated with an uplink/downlink imbalance. The underlay network node is assumed to be associated with a cell area A, and a cell extension area B, where the cell extension area B has an uplink/downlink imbalance in relation to a neighboring base station and the network node. The method in the underlay network node involves serving a UE in both uplink and downlink when the UE is located in cell area A. The method further involves serving a UE only in the uplink when the UE is located in cell extension area B, thus enabling avoidance of interference related to communication of a UE located in said cell extension area B.

Abstract: 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.

Abstract: In a method of generating a Level 2 message from a number of messages generated by at least one User Equipment (UE) in an idle state and transmitted on an enhanced Dedicated Channel, E-DCH a checksum to each Layer 3 (L3) message, e.g. (RRC or NAS) is added to check the correctness of the message. Hereby the need for transmitting a long Core Network (CN) Identity (ID) for contention resolution on Layer 2 for UEs in idle mode is removed. As a result performance of the cellular radio network will be improved.

Abstract: An object of the present invention is to provide a mechanism for improving coverage in a wireless communications system. The object is achieved by a method in a sending node (210) for transmitting a data unit to a receiving node (220). The data unit comprises a number of bits. The sending node (210) and the receiving node (220) are both comprised in a wireless communications system (200). According to the method, the sending node (210) obtains (606, 810) a value n associated with the data unit. Then, the sending node (210) selects (608, 814) a transmission time instance depending on n , such that a function exists that uniquely associates the selected transmission time instance with n . Finally, the sending node (210) transmits (612, 818) the data unit to the receiving node (220) in the selected transmission time instance, without the value n.

Abstract: UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8-n) bits, where n = the number of bits in C/T field.

Abstract: Data units according to the first transmission format are divided into data units according to the second transmission format. A single-bit segmentation indicator inserted into the header of a data unit according to the second transmission format indicates whether the data unit according to the first transmission format ends in a data unit according to the second transmission format.

Abstract: The present invention relates to a method, a user equipment and a network node in a cellular radio network. According to the method of the present invention, the network units detects a failed transmission of a handover command to the UE, which is still having a uplink channel available, and further receives a RRC message from the UE indicating the loss of a serving cell and indicating the strongest cell. The network unit prepares and initiates a new serving cell re-establishment and sends to the UE a RRC reconfiguration message. The UE can then continue normal operation in the new cell.

Abstract: According to the invention data in a number of logical downlink channels (PCCH, CCCH, BCCH, CTCH, MCCH, MSCH and MTCH) intended for one or more mobile terminals are received in a first mapping unit (10), where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel (HS-DCH) and processes said data.
