    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: Decoding a received Orthogonal Frequency Division Multiplex (OFDM) signal that occupies a first set of subcarriers in a radio frequency spectrum includes ascertaining an interference model that represents interference occurring in the first set of subcarriers caused by a transmitted OFDM signal that occupies a second set of subcarriers in the radio frequency spectrum. A set of scaled soft values is produced that represents information conveyed by the received OFDM signal over the first set of subcarriers, wherein each scaled soft value in the set of scaled soft values corresponds to a respective one of the subcarriers in the first set of subcarriers, and wherein a scaling amount applied to each of the scaled soft values is based on a corresponding level of interference in said respective one of the subcarriers as indicated by the interference model. A decoding process is performed that generates detected data from the scaled soft values.

    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: 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: According to the teachings presented herein, a method and apparatus provide a reduced search space for blindly decoding a message included in a signal received at a communication receiver, where the message has an unknown format. Improving blind detection efficiency in this manner offers numerous advantages, including but not limited to lower power consumption through reduced processing overhead, and lower power consumption through expanded sleep opportunities. As a non-limiting example, the communication receiver comprises a mobile station configured for operation according to Long Term Evolution (LTE) standards, as promulgated by the 3GPP for E-UTRA systems, where the mobile station is configured to reduce a search space of DCI message decoding by determining message format likelihoods and blindly decoding a received DCI message based on the message format likelihoods.
