A method for measuring the transmission quality between a base station and at least one remote station in a communication network having at least one channel for transferring signals between said base station and said at least one remote station involves measuring a transmission quality for signal transmissions via said at least one channel, and defining a transmission quality measurement period for said at least one channel in relation to said measured transmission quality. Moreover, a system for a communication network having at least one base station and at least one remote station transferring signals between each other via at least one channel carries out the method of measuring the transmission quality, wherein the system comprises measuring means for measuring transmission qualities for signal transmissions via said at least one channel, means for the definition of at least one transmission quality measurement period for signal transmissions between said base station and said at least one remote station, and control means for the measurement of the transmission qualities during said at least one transmission quality measurement period.

A method of transmitting a status report from a receiving terminal to a transmitting terminal is disclosed. A receiving terminal generates a status report according to a first retransmission protocol implemented by a higher layer protocol layer and sends the status report to a transmitting terminal in one or more data units of a lower layer protocol. If the lower layer data units are not successfully received, the lower layer protocol provides a failure indication, referred to as a local NACK, to the higher layer protocol. In response to the failure indication, the higher layer protocol generates an updated status report and sends the updated status report from the receiving terminal to the transmitting terminal.

According to the invention data in a number of logical downlink intended for one or more mobile terminals are received in a first mapping unit, 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 and processes said data.

The present invention relates to a method and an arrangement for reducing a state transition time from a power saving state for a user equipment (18) in a communication network. The state transition time is reduced by retaining in the user equipment (18) one or more information parameter, such as the radio network temporary identifier for a high speed downlink shared channel (H-RNTI), when performing a state transition to said power saving state so as to enable a time reduction when said user equipment switches back from said power saving state.

A method of optimising the use of radio resources in a mobile radio communication system during a combinational multimedia session involving circuit switched and packet switched sessions between user terminals, the method comprising: disabling an in-sequence delivery option of packets between radio network control nodes of the radio access network(s) serving the user terminals for said packet switched session.

Method and arrangement in a source radio network node for reducing the amount of user equipment related data forwarded to a target radio network node, when performing a handover of a user equipment. The method comprises determining that the user equipment is to perform a handover from the source radio network node to the target radio network node, increasing the polling frequency of polls sent to the user equipment, transmitting a poll to the user equipment, receiving a status message from the user equipment, as a response to the transmitted poll, dropping the data which, according to the received status message have been acknowledged by the user equipment, and forwarding the data which have not been acknowledged by the user equipment according to the received status message, to the target radio network node.
摘要:
A method (400) for use in a cellular system with at least one controlling node (110), eNodeB, which controls user terminals, UEs (130), in a cell (120). According to the method, a UE can be in one of at least two different states (410), an idle state, a DRX state, and an “on duration” state. A UE (130) can receive at least a first (420) and a second (425) type of traffic from its eNodeB (110). If (415) the first type of traffic is received by a UE during an on duration period, the UE assumes the idle (DRX) state at the end of the on duration period, and if (430) the second type of traffic is received by the UE during an on duration period, the UE prolongs the current on duration period by a certain amount of time.

Systems, devices, methods and software according to these exemplary embodiments provide for reducing the number of different sequence numbers used to transmit radio link control, RLC, data blocks to avoid, for example, sequence number stalling. This can be accomplished by, for example, transmitting or receiving RLC protocol data unit, PDU, segments as the initial or original instance of data communication.
摘要:
The present invention relates to an improved procedure for synchronization of re-configuration of RRC procedures between the radio base station and the UE. This is achieved by associating a new configuration to be used by a UE with an additional UE identity. The UE is normally identified by a first UE identity, but is informed in a re-configuration message that the UE also has the additional UE identity. The UE is identified by the additional UE identity when the new configuration is to be activated. Hence, when the radio base station detects that the UE responds to requests, which included the additional UE identity, the radio base station can conclude that the UE has activated the new configuration.
