    Abstract: A method of operating a terminal in a radio access network may include receiving a transmission of first and second data blocks over respective first and second multiple-input-multiple-output (MIMO) layers during a transmission time interval (TTI). Respective first and second demodulated codewords may be generated corresponding to the transmission of the first and second data blocks, and the first and second demodulated codewords may be decoded. Responsive to failure decoding the first demodulated codeword and success decoding the second demodulated codeword, a negative acknowledgement may be transmitted indicating failure receiving the first and second data blocks.

    Abstract: A MIMO (Multiple-Input-Multiple-Output) receiver may receive a plurality of MIMO transport blocks transmitted from a plurality of MIMO transmission antennas over a same carrier frequency. More particularly, a MIMO signal including the plurality of MIMO transport blocks may be received through a plurality of reception antennas, and respective measures of signal quality for each of the MIMO transport blocks may be computed. A MIMO transport block may be selected from the plurality of MIMO transport blocks based on the measures of signal quality, and the selected MIMO transport block may be decoded. Responsive to failure decoding the selected MIMO transport block, processing of all MIMO transport blocks received in the MIMO signal may be terminated.

    Abstract: A system and method to provide intelligent scheduling of network resources when a user equipment (UE) is operating in a Frequency Division Duplex (FDD) wireless network with duty cycle limitation. Intelligent scheduling is accomplished in two stages—a training stage, and a scheduling stage. In the training stage, a training module in the eNodeB senses the Transmission Time Interval (TTI) pattern when the UE is “awake” (i.e., when the UE is transmitting power under a P % duty cycle (P

    Abstract translation: 当用户设备(UE)在具有占空比限制的频分双工(FDD)无线网络中操作时,提供网络资源的智能调度的系统和方法。 智能调度分两个阶段完成:训练阶段和调度阶段。 在训练阶段,当UE“唤醒”时(即当UE在P%占空比(P <100))发送功率时,eNodeB中的训练模块检测传输时间间隔(TTI)模式。 在调度阶段,基于来自训练阶段的信息,eNodeB中的调度器智能地将网络资源分配给UE以在上行链路和下行链路上进行传输。 因此,仅当UE“唤醒”时才分配资源,或者当唤醒时可以发送/接收ACK / NAK。 这种智能调度可以显着地减少系统中的重传,并且可以提高系统在占空比受限频带中的效率。

    Abstract: A method in a radio receiver arrangement for receiving data blocks of radio signalling. The method comprises receiving a plurality of data blocks over a radio interface from a transmitting side. The method also comprises applying a single hybrid automatic repeat request (HARQ) process to the plurality of data blocks, whereby it is determined that at least one of the plurality of data blocks has been received ok and that at least one of the plurality of data blocks has not been received ok. The method also comprises generating a negative acknowledgement (NAK) for the plurality of data blocks in response to the at least one of the plurality of data blocks having not been received ok. The method also comprises outputting, from the receiver arrangement, at least one symbol obtained from the at least one of the plurality of data blocks which has been received ok.

    Abstract: A system and method for configuring a variable Channel Quality Information (CQI) reporting period based on a User Equipment's (UE) Doppler frequency or speed. Mobile users are divided into three Doppler frequency regions based on their speed—for example, low, medium, and high Doppler users—and are assigned the CQI, reporting periods accordingly by the base station. The users in the low and high Doppler regions (i.e., UEs with low and high speeds) receive a high value for the CQI reporting period, whereas—the users in the medium Doppler region (i.e., UEs with medium speeds) receive a low value for the CQI reporting period. The UE speed-specific CQI reporting period improves the uplink capacity by adaptively controlling a UE's CQI-related uplink transmissions, without compromising on the downlink capacity/throughput.
