  • Patent number: 11051208
    Abstract: Resources used for downlink communication may be partitioned by the base station so that a portion of the resources is reserved for the downlink transmission of low latency data. However, low latency data may be bursty or sporadic in nature, and may be transmitted in short packets. Therefore, there may not always be low latency data at the base station that needs to be transmitted using all of the low latency resources. System and methods are therefore disclosed in which the base station opportunistically schedules, on the low latency resources, latency tolerant data for one or more latency tolerant UEs. When latency tolerant data is scheduled on the low latency resources, signaling is used to indicate if the latency tolerant transmission on the low latency resources is modified.

  • Patent number: 10945206
    Abstract: This specification discloses methods and devices to enable high resolution configuration of a low-power wake-up detector (LP Detector), which in turn is implemented allowing for very coarse threshold detection (i.e., the detectable threshold levels are widely spaced apart from each other) due to power consumption and design reasons. Based on this invention, the detection resolution can be enhanced from 10 mV steps to <1 mV steps. This makes the detection configuration more accurate, which allows for improved calibration, and reduces false wake-ups by smartly controlling hardware at no additional cost in power consumption. In some embodiments, the invention to enable high resolution configuration of a low-power wake-up detector (LP Detector) can be implemented by using a wake-up threshold control to control both a low-power wake-up detector (LP Detector) and an attenuator belonging to a receiver.

Some embodiments include a UWB receiver that can inspect a channel impulse response (CIR) between a first and second electronic device and identify one or more first path candidates (FPCs). For a candidate path, the UWB receiver can identify subsequent paths that create inter-pulse interference (IPI) on the candidate path. Using estimates for the interfering path strengths (e.g., channel coefficients from the CIR) and the known cryptographically sequence of pulse polarities (SPP), the UWB receiver can reduce the IPI from these interfering paths on the FPCs, and then make decisions based at least on the remaining pulse polarities, whether the one or more FPCs comprise a legitimate transmission signal.

  • Patent number: 10813130
    Abstract: The present invention relates to cognitive wireless sensor network technologies, and in particular to a medium access control method for a cognitive sensor network based on broadcast preamble sampling. A cognitive node in the cognitive sensor network adopts a periodical dormancy-awakening mechanism. Firstly, a state of a primary user is judged by using a spectrum sensing technology. If the primary user is not active, a data sending node establishes a communication link by using a broadcast preamble code. Each neighbor node simultaneously considers information of hops from a gateway according to an awakening order, and independently determines to serve as a relay node for forwarding data. Furthermore, a transmission conflict between the cognitive node and the primary user may be caused due to return or missed alarm of the primary user. The present invention adopts a retransmission mechanism based on confirmation to ensure transmission reliability of data packets.

  • Patent number: 10785800
    Abstract: Systems and methods for dynamically selecting energy detection thresholds (EDTs) in radio nodes deploying listen before talk within a coordinated network to improve throughput on shared spectrum are disclosed. The radio nodes are configured to coordinate to deploy mechanisms to avoid or reduce interference issues, including collisions, with use of shared spectrum (e.g., unlicensed spectrum). One such mechanism is Listen Before Talk (LBT), and a radio node deploying LBT sets an EDT at which the radio node hears traffic from neighboring radio nodes on the shared spectrum. In an exemplary aspect, the EDT of radio nodes in the coordinated network of radio nodes can be dynamically selected and/or adjusted to improve throughput of the individual radio nodes and/or of the network of radio nodes as a whole.

  • Patent number: 10778395
    Abstract: A method is provided for reporting feedback information of Multicast-Broadcast Single-Frequency Network (MBSFN) transmission by a user equipment in a wireless communication system. The user equipment receives configuration information for feedback information of the MBSFN transmission when the user equipment receives signals from a plurality of base stations based on the MBSFN transmission, and transmits the feedback information measured in a resource region according to the configuration information. The user equipment receives a common reference signal (CRS) of an antenna port 0 of an interference cell from the interference cell in an MBSFN area, and the feedback information is measured in the resource region considering a position of a symbol allocated the CRS of the antenna port 0 of the interference cell.

  • Patent number: 10771200
    Abstract: Embodiments of a mobile device and method of communication are generally described herein. The mobile device may be configured to operate as a slave device for a Bluetooth link with a master device. The mobile device may transmit a packet in an ESCO interval. The mobile device may, in an ESCO retransmission slot of the ESCO interval: attempt to decode, from the slave device, a request for retransmission of the packet. If the request for retransmission is not successfully decoded, the mobile device may determine whether the request for retransmission was sent during the ESCO retransmission slot based at least partly on a channel energy level detected during the ESCO retransmission slot. If it is determined that the request for retransmission was not sent during the ESCO retransmission slot, the mobile device may refrain from monitoring subsequent ESCO retransmission slots of the ESCO interval.

  • Patent number: 10764877
    Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an AP, that reduce the overhead associated with triggering an uplink transmission from the STA. In some examples, the STA may also calculate its transmit power by decoding a spatial reuse subfield of the trigger frame from the AP and identifying downlink pathloss measurements of the trigger frame. Accordingly, the STA may identify acceptable interference level of the AP and calculate a transmit power in order to minimize interference at the AP. In some aspects, the STA may transmit its uplink packets to a different AP on one or more punctured channels at the calculated transmit power of the STA.

  • Patent number: 10743201
    Abstract: Joint demodulation of a desired transmission and an interfering transmission received from an interfering cell with an unknown combination of transmission parameters is performed. For each subcarrier, an exhaustive search for the serving cell symbols and projection for the interfering cell symbols is performed for tested hypotheses of the interfering cell, by minimizing a whitened noise parabola for each combination of searched hypothesis and hyper constellation point of the serving cell. A constellation point for the interfering cell that is closest to the minimum point of the parabola is selected, where coefficients of the parabola are calculated once for each subgroup of four modulation types of the interfering cell. A measure of likelihood for each of the tested hypotheses is calculated. A cumulative measure of likelihood for each of the tested hypotheses is calculated, and the most likely hypothesis is selected based on the cumulative measure of likelihood.
