摘要： In one embodiment, a method of scheduling transmissions for a base station in a multi-carrier wireless communication network comprises scheduling initial transmissions of data packets for one or more users on a first carrier, without reserving scheduling capacity on the first carrier for retransmissions. Doing so increases the scheduled capacity of the first carrier for initial transmissions. The method further includes scheduling retransmissions, as needed, for given ones of the data packets on one or more second carriers. The method allows more traffic to be scheduled on the first carrier, meaning that multi-carrier transmissions are less frequently needed to convey all of the traffic targeted to one or more receivers. Those receivers therefore spend more time operating with a reduced receiver bandwidth (as compared to the bandwidth required for receiving more than one carrier), which reduces operating power.

摘要： A user equipment (UE) located in an extended-range area of a neighbor base station cell in a communication network, such as a low-power cell in a heterogeneous network, can inform its serving base station, such as a macro cell overlying the low-power cell, of the UE's capability of canceling interference from other cells' transmissions. That capability information enables the serving cell to decide based on more information whether range extension of the neighbor cell is beneficial for a number of UEs, and can result in more efficient radio resource utilization.

摘要： A wireless communication transceiver compensates a given received signal for retransmission interference, if (uncompensated) decoding of the given received signals fails. The transceiver estimates the retransmission interference bearing on the given received signal based on hypothesizing that another user (or users) mistakenly transmitted in the same time interval, using some or all of the same channel resources as were allocated to the given received signal. The transceiver may retain information in any given interval, indicating the channel allocations used for those user signals successfully received in that interval. The retained information allows the transceiver to determine, with respect to a given signal received in a current time interval, which other users would be interfering users if they mistakenly retransmitted in the current time interval. The transceiver may target its compensated decoding, which may be iterative, to the most likely and/or most significant ones of the potentially of interfering user(s).

摘要： In one or more aspects, the method and apparatus presented herein consider corresponding uplink resource allocations when allocating ARQ signal powers. In particular, in at least one embodiment, more power is allocated to the acknowledgment (“ack”) signal(s) corresponding to user equipment (UE) transmissions that involve larger allocations of uplink resources. For the example context of an LTE network, an eNodeB “boosts” its ack signaling power for acknowledging UE transmissions associated with larger uplink bandwidth allocations. Additionally, or alternatively, the UE is configured to bias its ARQ signal evaluations, to bias its ack/nack decision determinations to favor the ack decision, at least for those acks associated with transmissions that used greater resource allocations.

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： 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.
