摘要： A technique is provided for processing data in a packet-based communications environment. A single data packet is encapsulated into a single link layer packet data unit. The link layer unit is encoded to form at least one code block. After the currently available radio resource capacity during a fixed duration transmission interval has been determined, bits within the code block are selected to fit into or otherwise match the radio resource capacity. Thereafter, the selected bits are transmitted via a physical layer. In some variations, unsolicited redundant sets of bits are transmitted thereafter to facilitate successful receipt.

摘要： The invention discloses a mobile station (200), a base station (300), a method and a computer program for communication in a wireless communication network (100), where cell edge user experiencing difficulties on the contention-based channel are treated differently than those users who are not power limited and/or do not experience collisions. Suggested solutions to this problem may be different treatment of the cell edge users in contrast to users located closer to the base station (300) either by communication over an orthogonal scheduled channel, or by forcing mobile stations (200) who have successfully sent their data to wait a specific time period or by dividing the mobile stations (200) into different groups based on the signal attenuation experienced by the different mobile stations (200).

摘要： Methods and arrangements 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 system. The status report comprises positive and/or negative acknowledgement of data sent from the first node, to be received by the second node. The methods comprises the steps of: detecting if any data units have been lost during the transmission, generating a status report, based on the made detection concerning lost data units, buffering the generated status report in a buffer, updating the buffered status report when a change concerning lost data units is detected, receiving a trigger for sending a status report to the second node, and transmitting the status report to the second node, as a response to the received trigger.

摘要： A relay node (29) radio access network (RAN) is configured to communicate using backhaul subframes over a Un radio interface with a donor base (27) station node and to communicate using access subframes over a Uu radio interface with a wireless terminal (30). Downlink backhaul subframes and downlink access subframes are transmitted over an air interface using the same frequency band, but a beginning of a selected downlink access subframe precedes a beginning of a next-in-time downlink backhaul subframe by a downlink timing advance (TA). The relay node (29) both receives downlink control information from the donor base station node and transmits downlink control information to the wireless terminal during the downlink backhaul subframe, e.g., during a time to which the downlink backhaul subframe has been allocated.

摘要： An apparatus, method, and system for dynamically assigning orthogonal codes to different information signals communicated between a Node B and user equipment in a cellular radio communication system in which a fixed number of codes are allocated between dedicated transport channels (DCHs) and high speed downlink shared channels (HS-DSCHs). A radio controller (RNC) allocates a minimum number of codes for HS-DSCH physical channels (HS-PDSCH codes) to the Node B. The Node B determines HS-PDSCH codes that are not currently being utilized and allocates HS-PDSCH codes from the unused codes without having to communicate with the RNC. When the additional HS-PDSCH codes are needed for DCH codes, the Node B reallocates the codes for DCH purposes without reducing the number of HS-PDSCH codes below the allocated minimum.

摘要： A serving RNC signals the load contribution of all mobiles for which it is the serving RNC to all cells controlled by another RNC that are affected by the uplink transmissions of those mobiles. This allows the other RNC to determine the contribution of those mobiles to the total uplink interference in its cells. In one example, the uplink load maybe estimated using mobile-based path gain measurements.

摘要： A method, system and apparatus for spreading physical channels using partly orthogonal multiple code trees. A portion of a first code tree is used to spread the physical channels. This first code tree is a combination of a channelization code sequence and a first scrambling code sequence. A portion of a second code tree is used to spread the physical channels that are remaining and were not spread using the first code tree. This second code tree is a combination of the channelization code sequence and a second scrambling code formed by modifying the first scrambling code. The portion of the second code tree used to spread the channels is orthogonal to the portion of the first code tree used. A plurality of other code trees could be formed using scrambling codes based on the modification of the first scrambling code.

摘要： A method for downlink power control in wireless communication systems is provided. In response to a transmitter power change request from a mobile terminal (110) over a wireless connection, a power control parameter is determined at network level based on connection-specific information indicating the degree of priority of the connection (DPIi). The power control parameter preferably relates to a maximum connection-specific transmitter power, a power step size and/or a quality target, and is used by the base station to distribute transmitter power (pi) to the connection.
