摘要： One aspect of the present invention concerns the management of processing resource allocations for a Turbo receiver, where such resources are consumed from a finite resource budget within a defined processing time interval. The contemplated Turbo receiver attempts to allocate more processing resources to those demodulation and/or Turbo decoding tasks that make more valuable contributions with respect to the ultimate goal of successfully decoding all data streams that are of interest in a received signal. The advantageous management approach allows the Turbo receiver to obtain better results for a given consumption of processing resources, and further permits the Turbo receiver to quit upon either achieving a successful outcome within a defined processing time interval or exhausting the budgeted resources.

摘要： In one or more aspects, the present invention improves the efficiency of soft information transfer within a soft-value processing apparatus, by reducing in some sense the “amount” of soft information transferred between constituent processor circuits within the apparatus, without forfeiting or otherwise compromising the transfer of “valuable” soft information. In one example, the soft values produced by a constituent processor circuit are identified as being reliable or unreliable according to a reliability threshold. Some or all of the unreliable values are omitted from a soft value information transfer to another constituent processor circuit, or they are quantized for such transfer. The reduction in memory requirements for soft information transfer advantageously allows the use of lower power, less complex, and less expensive circuitry than would otherwise be required in the apparatus, which may be, as a non-limiting example, a Turbo receiver in a wireless communication device.

摘要： The systematic and parity bits of a symbol are tightly coupled to each other based on the way in which the symbol is encoded. The relationship between the systematic and parity bits can be exploited to improve the accuracy of soft bit estimation for both the systematic bits and parity bits. In one embodiment, a received symbol is processed by demodulating the received symbol to determine an initial soft estimate of each systematic bit and corresponding one or more parity bits in the sequence. The systematic bit sequence is iteratively decoded to revise the soft estimate of the systematic bit. The initial soft estimate of the one or more parity bits associated with each systematic bit is revised based on the revised soft estimate of each systematic bit. The received symbol can be decoded or regenerated based on the revised soft estimate of each systematic bit and corresponding one or more parity bits.

摘要： Mechanism to receive control signals transmitted from a base station (210, 510, 910) to the user equipment (220, 520, 920) in a manner that minimizes power consumption on the user equipment (220, 520, 920) while still maintaining some acceptable level of performance is described. The user equipment (220, 520, 920) periodically measures the signal quality of component carriers used by the base station (210, 510, 910) and requests control signaling (anchor) carrier reselection. Either a single component carrier can be chosen if the single carrier has sufficient quality or multiple component carriers can be selected when the quality of the single quality is low. The anchor carrier reselection may also be triggered to manage the system as a whole. For fast moving user equipments (220, 520, 920), anchor carrier hopping pattern can be provided to increase robustness and reduce reselection signaling overhead.

摘要： A method for an electronic receiver of processing a packet of a hybrid automatic repeat request (HARQ) system is disclosed. The method comprises receiving a first transmission of the packet, wherein the first transmission comprises a first plurality of soft symbol values and determining whether the first plurality of soft symbol values meets a stop criterion. If it is determined that the first plurality of soft symbol values does not meet the stop criterion, a subject of the first plurality of soft symbol values is determined, wherein the subset comprises a number of soft symbol values of the first plurality of soft symbol values, the number being greater than zero and less than the first plurality. The subset of the first plurality of soft symbol values is stored in a HARQ buffer. A second plurality of soft symbol values, comprised in a second transmission of the packet received by the electronic receiver, is combined with the stored subset of the first plurality of soft symbol values to produce a third plurality of combined soft symbol values. Corresponding arrangement, receiver, device, and computer program product are also disclosed.

摘要： A method for allocating orthogonal sequences to user equipment devices, UEs, of a group sharing a channel of a telecommunication system is disclosed. The method comprises determining which UE of the group having largest transmission resource assigned for a physical up-link shared channel, PUSCH; determining a first orthogonal sequence of the UE of the group having largest transmission resource assigned; determining a second sequence that equals a quadrature phase offset of the first orthogonal sequence; reserving said second sequence when allocating sequences to remaining UEs of the group by avoiding the second sequence as long as there are other orthogonal sequences available. A control circuitry for a network node is also disclosed.

摘要： A terminal with transmitter and receiver operates in a multi-carrier communication system and receives at least two downlink carriers. One or more timing advance commands are received, each associated with a group of one or more uplink carriers, each group being associated with one or more of the received downlink carriers. For each downlink carrier associated with one of the groups of uplink carriers, one is selected as a reference downlink carrier; the reference downlink carrier timing is ascertained; and a transmission time period is ascertained based on the timing of the downlink reference carrier and an offset specified by the timing advance command associated with the group of uplink carriers. The transmission time period comprises a start time and a stop time. Transmission is initiated at an earliest transmission start time of the ascertained transmission time periods and is ceased at a latest ascertained stop time.
