  • Patent number: 11751181
    Abstract: A scheduling apparatus and a scheduling method, wherein the amount of signaling for frequency resource allocation information can be reduced while maintaining system throughput performance. In a base station apparatus, a scheduling section allocates frequency resources to frequency allocation target terminals based on set frequency allocation units, and a frequency allocation parameter setting section adjusts the set frequency allocation units set in the scheduling section based on cluster numbers. Due to this, in each cluster number, frequency resources can be allocated based on the most suitable frequency allocation units with respect to the signaling bit number. As a result, the amount of signaling for frequency resource allocation information can be reduced. Further, system throughput can be maintained by making the cluster number, which is a parameter having little effect on system throughput, a setting parameter for frequency allocation units.

In some systems, a user equipment (UE) may monitor sets of decoding candidates over a search space in each monitoring occasion to detect downlink control transmissions. Such a monitoring process may be resource intensive. To reduce the processing power involved in monitoring the control channel, a UE may measure resources associated with the downlink control channel to obtain a quality metric. The UE may compare the quality metric to one or more thresholds and may perform a decoding process on a set of configured decoding candidates for the downlink control channel based on the comparing. In some cases, if the channel quality is relatively good, the UE may perform a list decoding process using a list size less than a maximum list size or may perform partial data tone processing to reduce the processing complexity for some of the decoding candidates.

  • Patent number: 11483046
    Abstract: Techniques for transmitting channel state information (CSI) are described. In an example, a device determines a condition associated with a link parameter of a link between the device and another device. Based at least in part on the condition, the device determines a CSI packet period. The device transmits, to the other device and based at least in part on the CSI packet period, a CSI packet over the link. Accordingly, when the conditions change, the CSI packet period can be adapted to the changes, thereby improving the CSI transmissions over the link given the most current conditions.

  • Patent number: 11411685
    Abstract: A terminal is disclosed including a processor that, when an uplink shared channel is used to transmit a delivery acknowledgement signal (HARQ-ACK) and an uplink data (UL-SCH), controls a mapping of the delivery acknowledgement signal based on whether bundling is applied to the delivery acknowledgement signal and based on a number of bits of the delivery acknowledgement signal; and a transmitter that transmits the delivery acknowledgement signal and the uplink data. In other aspects, a radio communication method and a base station are also disclosed.

  • Patent number: 11387976
    Abstract: Examples described herein include apparatuses and methods for full duplex device-to-device cooperative communication. Example systems described herein may include self-interference noise calculators. The output of a self-interference noise calculator may be used to compensate for the interference experienced due to signals transmitted by another antenna of the same wireless device or system. In implementing such a self-interference noise calculator, a selected wireless relaying device or wireless destination device may operate in a full-duplex mode, such that relayed messages may be transmitted as well as information from other sources or destinations during a common time period (e.g., symbol, slot, subframe, etc.).

  • Patent number: 11388699
    Abstract: A method of transmitting packets between a plurality of nodes of a network. The method comprising in each of a plurality of data timeslots, transmitting a data packet with one of the plurality of nodes and listening to receive the data packet with the remainder of the plurality of nodes. The method further comprising in each of one or more parity timeslots following the plurality of data timeslots, transmitting a parity packet with one or more of the plurality of nodes and listening to receive the parity packet with the remainder of the plurality of nodes. Each parity packet is derived from a set of the data packets transmitted during the plurality of data timeslots.

  • Patent number: RE49329
    Abstract: The teachings herein present a method and apparatus that implement and use a factorized precoder structure that is advantageous in terms of performance and efficiency. In particular, the teachings presented herein disclose an underlying precoder structure that allows for certain codebook reuse across different transmission scenarios, including for transmission from a single Uniform Linear Array (ULA) of transmit antennas and transmission from cross-polarized subgroups of such antennas. According to this structure, an overall precoder is constructed from a conversion precoder and a tuning precoder. The conversion precoder includes antenna-subgroup precoders of size NT/2, where NT represents the number of overall antenna ports considered. Correspondingly, the tuning precoder controls the offset of beam phases between the antenna-subgroup precoders, allowing the conversion precoder to be used with cross-polarized arrays of NT/2 antenna elements and with co-polarized arrays of NT antenna elements.
