  • Patent number: 11153034
    Abstract: A user equipment includes a receiver and a transmitter and is configured to report channel state information (CSI) to a base station in a communication system in which a plurality of downlink component carriers and at least one uplink component carrier are configured. The receiver receives, in a slot nTrigger, a trigger message that triggers reporting of the CSI for at least one unlicensed downlink component carrier of the plurality of downlink component carriers. The transmitter transmits, in a slot nReport, the CSI based on reference signals present in a slot nRS on the at least one unlicensed downlink component carrier. Responsive to the at least one unlicensed downlink component carrier being occupied for a period of time for a bursty downlink transmission, only the reference signals in the slot nRS are evaluated for the CSI, and other slots in the period of time are not evaluated for the CSI.

  • Publication number: 20210321435
    Abstract: The invention relates to a user equipment for being scheduled with uplink radio resources. The user equipment receives from a radio base station a first-stage uplink resource scheduling message, indicating uplink radio resources usable by the UE to perform an uplink transmission via an unlicensed cell. The receiver further receives a second-stage uplink resource scheduling message, which is related to the first-stage uplink resource scheduling message. Upon reception of the second-stage uplink resource scheduling message, a processor of the UE determines that an uplink transmission is scheduled in case the first-stage uplink resource scheduling message is valid. The first-stage uplink resource scheduling message is determined valid based on a determination as to whether an uplink transmission has been triggered by another second-stage uplink resource scheduling message within a predetermined time period prior to reception of the second-stage uplink resource scheduling message.

  • Publication number: 20210314121
    Abstract: An integrated circuit includes control circuitry and transmitting circuitry. The control circuitry maps data or a reference signal onto resources including orthogonal subcarriers of a first numerology and a second numerology, which differ at least by subcarrier spacing and are frequency-multiplexed on a subcarrier basis. The control circuitry assigns no transmit power to at least one subcarrier located between a subcarrier of the first numerology and a subcarrier of the second numerology. The subcarriers of the second numerology include: inter-numerology-orthogonal subcarriers, each of which is centrally aligned with a subcarrier of the first numerology, and non-inter-numerology-orthogonal subcarriers not centrally aligned with any subcarrier of the first numerology and located between two adjacent subcarriers of the first numerology. The control circuitry assigns no transmit power to at least one of the non-inter-numerology-orthogonal subcarriers.

  • Publication number: 20210288745
    Abstract: The present disclosure relates to transmitting transport blocks in subframes of a predefined length within a wireless communication system. A downlink control information including a resource grant comprising a predetermined modulation and a predetermined transport block size is received (user equipment is the transmitter) or generated (base station is the transmitter). Then transport block including channel coded data to be transmitted in a subframe with the predetermined modulation and the predetermined transport block size is generated. Sensing is performed in the subframes and based thereon, it is determined whether a partial subframe or a complete subframe is available for transmission of the generated transport block. Finally, the transport block is transmitted with a modified modulation different from the predetermined modulation if the partial rather than complete subframe is available.

  • Publication number: 20210288861
    Abstract: The present disclosure relates to adaptive modulation and coding scheme selection and signaling in a communication system. In particular, a modulation and coding scheme to be used for transmission of a data is selected from a set of predetermined modulation and coding schemes. The predetermination of the set is performed by selecting the set from a plurality of predefined sets. The sets have the same size, so that a modulation and coding selection indicator signaled to select the modulation and coding scheme may be advantageously applied to any of the selected sets. Moreover, a second set includes schemes with a modulation not covered by the schemes of a first set, and which is of a higher order than any modulation in the first set.

  • Patent number: 11122593
    Abstract: A base station is disclosed, which is capable of appropriately configuring the timings of data assignment, data transmission and reception, and feedback for a case where the DL and UL sTTI lengths are different from each other. In this base station (100), a transmission section (106) transmits a downlink signal using a first short transmission time interval (sTTI) shortened in length than a TTI and used for downlink; and a reception section (107) receives an uplink signal using a second sTTI shortened in length than the TTI and used for uplink. When the first sTTI is shorter in length than the second sTTI, the reception section (107) receives the uplink signal in the second sTTI positioned after a predetermined interval from the transmission timing of the downlink signal, the predetermined interval being configured based on the length of the first sTTI.

  • Publication number: 20210258129
    Abstract: This invention relates to a proposal of an uplink resource assignment format and a downlink resource assignment format. Furthermore, the invention relates to the use of the new uplink/downlink resource assignments in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, while minimizing the signaling overhead, the invention proposes a new uplink/downlink resource assignment format that allow the activation/deactivation of individual downlink component carriers configured for a mobile. The new uplink or downlink resource assignment comprises an indication of the activation state of the configured downlink component carriers, i.e., indicate which downlink component carrier(s) is/are to be activated or deactivated.

  • Publication number: 20210185673
    Abstract: Provided is a terminal apparatus that, when two terminals having mutually different subframe structure patterns are coexistent, can suppress DCI scheduling constraints of those terminals in a base station. In a terminal, a signal separation unit separates, from a received signal, both a response signal assigned to a first resource determined on the basis of a number of resources associated with the first subframes in which the signal was received and downstream control information assigned to a second resource. It should be noted that at a timing when both a first structure pattern that has been set in the terminal and a second structure pattern that has been set in another terminal that cannot change the setting of the structure pattern are the first subframes, the signal separation unit uses a number of resources associated with the first subframes of the second structure pattern.

  • Publication number: 20210168845
    Abstract: The invention relates to a method for dynamically indicating a TDD reconfiguration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication.

    Abstract: The invention relates to an improved transmission protocol for uplink data packet transmission in a communication system. A receiver of a user equipment receives a Fast Retransmission Indicator, referred to as FRI. The FRI indicates whether or not a base station requests a retransmission of a previously transmitted data packet. A transmitter of the user equipment retransmits the data packet using the same redundancy version as already used for the previous transmission of the data packet.
