  • Patent number: 11362767
    Abstract: A receiver includes an antenna, a transceiver coupled to the antenna, a decoder and a processor. The transceiver receives from a transmitter of a wireless communication network a data block. The data block includes encoded data transmitted on a plurality of resources allocated to the receiver. The decoder decodes the encoded data and determines for the allocated resources whether decoding of the encoded data was successful or failed. The processor evaluates whether one or more of the resources for which the decoding failed are included in a report, the report indicating for one or more of the allocated resources that encoded data transmitted on the one or more allocated resources is not decodable or is likely to be not decodable, and causes the transceiver to send a retransmission request to the transmitter responsive to the evaluation.

  • Publication number: 20220182879
    Abstract: An apparatus for a wireless communication system uses a plurality of frequency bands for a communication with one or more network entities. The apparatus receives a transport block, TB, which is split into a plurality of code block groups, CBGs, comprising one or more code blocks, CBs, confined to one of the plurality of frequency bands. The apparatus provides or predicts a feedback for each CBG indicating one or more of a successful receipt, a non-successful receipt, no need for redundancy and a need for some redundancy. The apparatus compresses the feedbacks for each CBG into a compressed feedback based on an interference pattern on one or more of the frequency bands which is detectable at the apparatus and the transmitter or the one or more network entities, e.g. Listen-before-Talk, LBT, failure, and to transmit to the one or more of the network entities the compressed feedback.

  • Publication number: 20220150968
    Abstract: A user device, UE, for a wireless communication system is served by a base station and uses one or more frequency bands for a communication with one or more entities, e.g., other UE(s) or other gNB(s), in the wireless communication system. Some or all of the plurality of frequency bands are unlicensed frequency bands on which a communication is allowed for a certain transmission time (COT) responsive to a successful channel access procedure e.g. Listen-Before-Talk, LBT. The UE is configured, e.g., using an RRC signaling, with one or more configured grant, CG, configurations so as to allow the UE to perform one or more CG transmissions. Responsive to detecting a COT and a potential collision of a CG transmission with the COT, e.g. the COT of another entity, e.g., other UE(s) or other gNB(s), in the wireless communication system, the UE deactivates or backs off the CG transmission.

  • Publication number: 20220109554
    Abstract: The present invention is concerned with different novel concepts for reducing latency in data transmission. These concepts may be exploited by a transceiver configured to perform wireless data communication with a third party device by aggregating time division duplex carriers having different temporal distribution of uplink times and downlink times. These concepts may further be exploited by an apparatus configured to perform data transmission or reception via allocations of transmission resources of aggregated carriers in units of transmission time intervals into which the aggregated carriers are subdivided, wherein the aggregated carriers are temporally subdivided into the transmission time intervals in a temporal grid, respectively, wherein the aggregated carriers' grids are temporally mutually offset.

  • Publication number: 20220061090
    Abstract: An apparatus, for wideband communication with one or more transceivers in a wireless communication system using one or more subbands of a predefined wideband, is configured to perform initial Listen-Before-Talk, LBT, for each subband of the predefined wideband so as to determine from the predefined wideband one or more non-occupied subbands on which the wideband communication is allowed during a certain transmission time, and during the certain transmission time, transmit to and/or receive from the transceiver using the non-occupied subbands. During the certain transmission time and in case the initial LBT indicted that one or more of the subbands are occupied, the apparatus is configured to perform a further LBT for the one or more occupied subbands so as to determine one or more of the initially occupied subbands being no longer occupied, and transmit to and/or receive from the transceiver using, in addition to the initially non-occupied subbands, the one or more no longer occupied subbands.
