  • Patent number: 10498493
    Abstract: A method for retransmission of uplink transmissions, performed by a wireless device with configured uplink grants. The method comprises transmitting a first transmission to a network node with a redundancy version (RV). The wireless device then determines to retransmit the first transmission, and retransmits the first transmission with a retransmission RV based on the type of retransmission. For a non-adaptive retransmission, the retransmission RV value is the same as the RV of the first retransmission. For an adaptive retransmission, the retransmission RV is the RV value received in a retransmission grant.

  • Patent number: 10499378
    Abstract: A method and a network node, for handling a feedback procedure requiring transmission of feedback messages on a reverse link to indicate either an ACK or a NACK of correct reception of data transmitted on a forward link in a radio communication with a wireless device. The network node obtains (300) a quality of the forward link and determines (302) an expected data error rate on the forward link based on the quality of the forward link. The network node then assigns (306) radio resources on the reverse link for transmission of the feedback messages based on the expected data error rate, so that more radio resources are assigned for the reverse link when the expected data error rate is relatively high than when the expected data error rate is relatively low. Thereby, the amount of radio resources on the reverse link can be adapted to the expected data error rate such that any waste of radio resources to no avail can be reduced.

    Abstract: A radio node (52) in a wireless communication system (10) employs multiple different candidate formats (22) that define different possible positions of decoding checks (24) within a transport block of a specific size. The radio node (52) determines, from these different candidate formats (22), a format that defines a position of decoding checks (24) within a transport block (16) to be encoded or decoded. The radio node (52) then encodes or decodes at least a portion of the transport block (16) based on the determined format.

  • Publication number: 20190334662
    Abstract: According to some embodiments, a method in a radio network element of providing hybrid automatic repeat request (HARQ) feedback comprises receiving, from a wireless transmitter, a first set of coded bits. The first set of coded bits comprises a partial subset of coded bits to be received during a transmission time interval (TTI). The radio network element decodes the first set of coded bits; determines a first decoding indicator based on the success or failure of the decoding of the first set of coded bits; and communicates the first decoding indicator to the wireless transmitter. Particular embodiments communicate the first decoding indicator to the wireless transmitter within four TTI of receiving the first set of coded bits. Particular embodiments estimate a decoding indicator for the entire TTI based on the success or failure of the decoding of the first set of coded bits.

  • Patent number: 10447439
    Abstract: In a mobile network, the transmission of downlink data blocks (303, 307) to one or more terminal devices (200, 210) is accomplished on the basis of a retransmission protocol with a first feedback time (F1) defining a time interval between transmission of a first data block (303) and transmission of a first feedback message (308) being different from a second feedback time (F2) defining a time interval between transmission of a second data block (307) and transmission of a second feedback message (309). The first feedback message (308) indicates whether the first data block (303) was successfully received, and the second feedback message (309) indicates whether the second data block (307) was successfully received. A base station (100) of the mobile network controls the terminal device (200, 210) to send the second feedback message (309) on other resources than used for transmission of the first feedback message (308).

  • Patent number: 10433268
    Abstract: A device operates in a cellular communications network by detecting a timing signal from a serving base station, obtaining timing information from at least one other base station, and setting a value for a transmission time offset based on the detected timing signals from the serving base station and the at least one other base station. The device then transmits signals to the serving base station using the set value for the transmission time offset. The device may obtain the timing information from at least one other base station by detecting a timing signal transmitted by the at least one other base station, and subtracting the timing difference between the detected timing signals from the serving base station and the one other base station from a predetermined baseline time offset.

  • Patent number: 10383011
    Abstract: Small base station, micro, femto or pico BTS (PBS) are connected via Un interface to a donor eNB DeNB. In case of a handover from that PBS packets that had not been acknowledged by a UE need to be forwarded to the target base station. Forwarding them via Un and DeNB to the target eNB causes latency and wast radio resources on Un. Thus, the DeNB uses information about the handover to buffer packets and, after being informed by PBS, forward those packets that had not been acknowledged by the UE. This procedure, therefore, saves resources on Un interface and reduces latency. No forwarding of those packets from PBS to DeNB is required. There is provided a method for forwarding data to a wireless terminal. The method is performed by a proxy node. The method comprises receiving data on a link between a core network and a backhaul hub node. The data is addressed to a wireless terminal served by, or handed over from, a serving network node.
