摘要： A cellular communication system (100) comprises a first base station (103) which schedules resource for a user equipment (101). When receiving a resource allocation message, the user equipment (101) transmits a first message comprising a transmit indication to a plurality of base stations (103-109) wherein the transmit indication is indicative of a subsequent transmission of a second message. The user equipment (101) then proceeds to determine a transmit format for the second message; and to transmit the second message to the plurality of base stations (103-109) using the transmit format. When receiving the transmit indication, the plurality of base stations (103-109) proceed to configure their receivers to receive the second message. The first message may be transmitted in a control channel and the second message may be transmitted in a user data channel. The invention is particularly applicable to a High Speed Uplink Packet Access HSUPA service in a UMTS cellular communication system and may facilitate soft handover.

摘要： In a mobile telecommunication system (10), a number of user equipments (40–45) may receive multimedia broadcast multicast services. The method for power allocation and user assignment for MBMS services determines any number (K) of user equipments which may be served without complete cell area coverage (78). For more than K user equipments (40–45) requesting MBMS services, dedicated channels are assigned (84). For user equipments requesting MBMS service during a broadcast, such user equipment is assigned to the channel (broadcast or dedicated) with the lower power requirement, if power is available. If the user is assigned to the broadcast channel, and power is available, power of the broadcast channel is adjusted (108). Otherwise, the power of the broadcast channel is increased and no further power is indicated as being available (112).

摘要： The present invention relates to methods of operation of a communication device and to corresponding communication devices. In particular the invention relates to a first method of operation of a communication device, wherein some pilot bits associated with data bits are transmitted with a power at least partly dependent on the data rate at which the data bits are transmitted. At the base station, power control is carried out only on pilot bits with constant power, whereas channel estimation is carried out on all pilot bits. The invention also relates to a second method of operation of a communication device wherein all pilot bits associated with data bits are transmitted with one of a plurality of powers, at least partly dependent on the data rate at which the data bits are transmitted. At the base station a power control process compares the received signal with a plurality of thresholds, and sends a power control signal to the communication device based on the result of the comparison.

摘要： An improved turbo code based incremental redundancy includes a first step of puncturing a data stream for a first transmission to provide a set of first unpunctured trellis sections. A next step includes puncturing a data stream for a second transmission to provide a set of second unpunctured trellis sections. A next step includes incremental redundancy combining the first and second transmissions of the trellises to provide non-adjacent first and second unpunctured trellis sections. The above arrangement results in a uniform distribution of punctured and unpunctured bits to provide lower errors.

摘要： Various embodiments are described to address the need for an apparatus and method of outer-loop power control for enhanced uplink communications that address some of the outstanding problems in the prior art. Generally expressed, a base site (131), while a first uplink channel is inactive, monitors packet retransmissions to generate an uplink quality indicator. Here, packet retransmissions refers to the number of packet retransmissions used by a remote unit (101) to send packets to a base transceiver station (111) via at least one other uplink channel. Also, while the first uplink channel is inactive, the base site adjusts a signal-to-interference ratio (SIR) target for the first uplink channel based on the uplink quality indicator. Then, when the first uplink channel becomes active, the base site begins power controlling the first uplink channel using the SIR target.
