  • Patent number: 10256945
    Abstract: A method and device for performing Hforward error (FEC) correction avoidance based upon predicted block code reliability in a communications device is provided. An avoidance unit comprising a metric computation unit and a decision unit generates a reliability metric based upon a received code block. The reliability metric is compared to a reliability threshold, and the forward error correction decoder in the communications device is disabled if the metric is below or equal to the threshold.

  • Publication number: 20190059080
    Abstract: Methods, devices, and systems for the transmission of information in a wireless communication system are disclosed. In one embodiment, a method for the transmission of information in a wireless communication system comprises receiving a downlink message, wherein the downlink message includes a first control channel element; determining a first index using the location of the first control channel element; determining a second index; determining a first orthogonal resource using the first index; determining a second orthogonal resource using the second index; spreading an uplink message using the first orthogonal resource to form a first spread signal; spreading the uplink message using a second orthogonal resource to form a second spread signal; transmitting the first spread signal using a first antenna; and transmitting the second spread signal using a second antenna.

  • Publication number: 20190052487
    Abstract: Methods and devices are described for polar encoding and decoding control information that has been modulated based on one or more identifiers of the transmitter and/or receiver. Some embodiments describe scrambling sequence design for multi-mode block discrimination on control information blind detection and decoding. Separate scrambling masks may be applied to disparate bit fields within a coded DCI message, wherein each of the scrambling masks is derived from a user equipment (UE)-specific identifier, a UE group identifier, or a base station identifier. Frozen bits of the polar code may be used to encode and transmit hybrid automatic repeat request (HARQ) acknowledgment messaging for early retransmission of unsuccessful downlink messages. A tiered process of UE identification may be employed to improve a balance between early termination of the decoding process and success of the UE identification process.

  • Patent number: 10205619
    Abstract: A base station may generate and transmit a transport stream including a sequence of frames. A frame may include a plurality of partitions, where each partition includes a corresponding set of OFDM symbols. For each partition, the OFDM symbols in that partition may have a corresponding cyclic prefix size and a corresponding FFT size, allowing different partitions to be targeted for different collections of user devices, e.g., user devices having different expected values of maximum delay spread and/or different ranges of mobility. The base station may also dynamically re-configure the sample rate of each frame, allowing further resolution in control of subcarrier spacing. By allowing the cyclic prefixes of different OFDM symbols to have different lengths, it is feasible to construct a frame that confirms to a set payload duration and has arbitrary values of cyclic prefix size per partition and FFT size per partition. The partitions may be multiplexed in time and/or frequency.

  • Patent number: 10135517
    Abstract: A method for preventing a first network node from missing a transmission from a second network node. The method includes, when a ten millisecond periodicity is used for Multicast/Broadcast Single Frequency Network (MBSFN) subframes, setting a time between an uplink grant from the second network node to the first network node and an acknowledgement/negative-acknowledgement message (ACK/NACK) from the second network node to the first network node equal to ten milliseconds. The method further includes, when a forty millisecond periodicity is used for MBSFN subframes, the second network node sending the first network node an asynchronous grant for an uplink retransmission when a data packet is missed, and when the first network node receives the grant for the uplink retransmission, the first network node retransmitting the missed data packet.

  • Publication number: 20180309610
    Abstract: Techniques are disclosed relating to generating and receiving radio frames with multiple portions that have different encoding schemes. An apparatus may include one or more processing elements configured to receive, via a wireless radio, wireless data that includes a plurality of portions that each include multiple orthogonal frequency-division multiplexing (OFDM) symbols. Different ones of the portions have different frequency transform sizes and different sampling rates. The wireless data may also include control data that indicates the frequency transform sizes and sampling rates for the ones of the portions. The apparatus may select, based on the control data and a determined velocity of the apparatus, one or more but not all of the plurality of portions and may decode the selected one or more portions to determine data represented by the OFDM symbols in the selected one or more portions. Different portions of the wireless data may be adapted for decoding by devices moving at different maximum velocities.

    Abstract: In some implementations, a method in a user equipment (UE) for adaptively determining a wakeup period includes determining a power level of a Downlink (DL) transmission from a base station during a first wakeup period within a Discontinuous Reception (DRX) inactive time. The UE deactivates a RF receiver in response to the determination of the second wakeup period. The UE activates the RF receiver at a beginning of the second wakeup period prior to a DRX active time. The UE receives a DL paging channel transmission during the DRX active time.
