Slot Configuration in Control Channel Repetition
A wireless device may receive, via at least one physical downlink control channel (PDCCH) monitoring occasion of PDCCH monitoring occasions linked for repetition, at least one repetition of downlink control information (DCI) indicating reception of a downlink signal in a subset of symbols from a set of symbols configured for transmission of an uplink signal. A wireless device may cancel transmission of the uplink signal in one or more symbols, of the set of symbols, that occur after a time from a last symbol of a PDCCH monitoring occasion that ends latest among the PDCCH monitoring occasions.
Asymetric decision feedback equalization
Systems and methods for implementation of modified decision feedback equalization. In one embodiment, a method, includes sweeping a reference voltage signal across a set of voltages to find a center point of an eye diagram, determining whether an asymmetry is present in the eye diagram relative to the center point of the eye diagram, and when an asymmetry is determined to be present, generating a control signal to select a mode of decision feedback equalization to be applied to an input data bit.
Channel disruption wireless communication system
The wireless channel of the wireless communication system is selectively disrupted or interfered with based on the logical states of the data to be transmitted by an electronic device having no wireless data signal transmitting circuitry. A host device transmits a query packet which includes a header and a series of sub-frames to be received by a receiving device. As each sub-frame is transmitted, the electronic device can selectively disrupt the wireless channel by changing its characteristics such that the receiving device can no longer decode that sub-frame based on channel estimation from the header of the frame. Wireless channel disruption occurs in response to a specific state of the bit of data of a message to be communicated by the electronic device. The receiving device then issues a status reply to the host device indicating which sub-frames are decodable and which sub-frames are undecodable based on the initial channel estimation. The host device decodes the status reply to extract the message.
Enhanced processes for HARQ feedback
A wireless device may receive configuration parameter(s) of a time alignment timer associated with a cell. The wireless device may determine to defer transmission of a HARQ feedback, associated with a transport block, from a first timing to a second timing. The wireless device may transmit, via the cell, the HARQ feedback in the second timing based on the time alignment timer running in the second timing and regardless of whether the time alignment timer is running or is not running in the first timing.
TELEMETRY DATA ERROR DETECTION
A device may receive a first telemetry data entry associated with an attribute and store a record associated with the first telemetry data entry, wherein the record identifies a first context value associated with the attribute. The device may log a first timestamp of the first telemetry data entry in a lookup table, wherein the lookup table includes a mapping of the attribute to the first context value and to the first timestamp. The device may receive a second telemetry data entry associated with the attribute and may determine, from the mapping, that the second telemetry data entry is associated with a second context value that is different from the first context value. The device may determine whether a second timestamp, of the second telemetry data entry, is before the first timestamp. The device may perform an action based on whether the second timestamp is before the first timestamp.
PUCCH timing for terminal apparatus, base station apparatus, and communication method in a wireless communication system
A terminal apparatus includes a receiver configured to receive a PDCCH including a DCI format, and a transmitter configured to transmit a PUCCH. In a case that the DCI format schedules a PDSCH and that a last OFDM symbol of the PDSCH is mapped in a first slot, the PUCCH is transmitted in a second slot, the number of slots from the first slot to the second slot is given based on a PDSCH-to-HARQ-timing-indicator field, and a length of each of the slots is given based on a subcarrier spacing configuration of the PUCCH.
HARQ TXOP frame exchange for HARQ retransmission using HARQ threads
Embodiments described herein provide apparatus and methods for performing HARQ operations using parallel HARQ threads, where each new transmission of a Media Access Control (MAC) Protocol Data Unit (MPDU)/Aggregate-MPDU (A-MPDU)/Physical Layer Convergence Procedure (PLCP) Service Data Unit (PSDU) triggers the activation of a HARQ thread. Each HARQ thread contains one or more HARQ coding words or coding units. A HARQ thread index is setup by a transmission opportunity (TXOP) holder for a corresponding PSDU and is used to identify HARQ threads. Transmission information such as duration in formation for PPDUs including BA/HARQ-ACK feedback such as RX/TX addresses, etc. can be determined according to previous transmission values of a received PPDU (e.g., values of a MAC or PHY header).
Communication system, communication device, method, and recording medium of program
A receive terminal setting a non-delivery determination time for determining that a next data packet is not delivered after transmitting an acknowledgement (ACK) packet for a received data packet; when the next data packet is not delivered within the non-delivery determination time, the receive terminal repeatedly transmits a retransmission request (RACK) packet prompting the transmission of the next data packet; a transmit terminal specifies a non-delivered data packet using time difference information based on the time-of-day information of the received ACK packet and RACK packet and retransmits the specified data packet to the receive terminal; the time-of-day information here is a time stamp added by the receive terminal to each of the ACK packet and RACK packet when transmitted, or a time stamp added by the transmit terminal to each of the ACK packet and RACK packet when received.
In-vehicle information processing for unauthorized data
An information processing method performed by an information processing system including a storage device to process a plurality of data frames flowing in an in-vehicle network including at least one electronic control unit includes a receiving step of sequentially receiving a plurality of data frames flowing in the in-vehicle network, a frame collection step of recording, in a reception log held in the storage device, reception interval information indicating reception intervals between the plurality of data frames as frame information, a feature acquisition step of acquiring, from the reception interval information, a feature relating to distribution of the reception intervals between the plurality of data frames, and an unauthorized data presence determination step of determining the presence/absence of an unauthorized data frame among the plurality of data frames.
Telemetry data error detection
A device may receive a first telemetry data entry associated with an attribute and store a record associated with the first telemetry data entry, wherein the record identifies a first context value associated with the attribute. The device may log a first timestamp of the first telemetry data entry in a lookup table, wherein the lookup table includes a mapping of the attribute to the first context value and to the first timestamp. The device may receive a second telemetry data entry associated with the attribute and may determine, from the mapping, that the second telemetry data entry is associated with a second context value that is different from the first context value. The device may determine whether a second timestamp, of the second telemetry data entry, is before the first timestamp. The device may perform an action based on whether the second timestamp is before the first timestamp.
