    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 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.

    摘要: A method in a base station for selecting a set of transport format schemes for a cell is provided. The set of transport format schemes shall be used for a radio transmission from a communication device to the base station. The base station is serving the eel! comprising the communication device. The communication device is unsynchronized for transmission to the base station. The base station specifies (201) a plurality of sets of transport format schemes. Each set of transport format schemes is associated to a respective guard time, which guard time is a time margin required to compensate for the communication device being unsynchronized for transmission to the base station. After determining (203) a required guard time as the maximum timing advance value used in the cell the base station selects (204) one set of transport format schemes from the plurality of sets of transport format schemes to be available for the cell. The set is selected such that its associated guard time matches the determined required guard time in the cell.

    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: A radio communication system and a method for assigning a short-lived Cell Radio Network Temporary Identifier (C-RNTI) to a first user equipment performing random access to a radio network node are provided. The radio communication system registers the first user equipment as connected to the radio network node. A message for synchronizing the radio network node and the first user equipment with respect to the first time period is transferred. After the first time period has elapsed, the radio communication system maintains the first user equipment connected to the radio network node, and allows the short-lived C-RNTI to be assigned to a second user equipment. Furthermore, a first user equipment and method for enabling assignment of a short-lived C-RNTI to the first user equipment performing random access and a radio network node and method for assigning a short-lived C-RNTI to a first user equipment performing random access are provided.
