  • Patent number: 10812227
    Abstract: Modern mobile communication systems transfer data by error protection measures including the use of a forward error correction code for the channel coding and a HARQ (hybrid automatic repeat request) system for the repeated transfer of incorrect transport blocks in response to the error protection mechanisms failing. When a turbo code is used as an error protection code, two decoders work on the decoding of the turbo code. Disclosed is an expanded HARQ system wherein the receiving side determines which of the decoders was more greatly challenged in the decoding of the turbo code and reports this to the transmitting side. Instead of uniformly providing more redundancy data to both decoders, more redundancy data are targetedly provided to the more greatly challenged decoder in the expanded HARQ process than in the case of the repetition operation according to the typical HARQ process reducing the latency of the data transfer.

  • Patent number: 10757710
    Abstract: A wireless device receives message(s) from a base station comprising configuration parameters of a first uplink bandwidth part of a cell. The configuration parameters comprise: a bandwidth part configuration parameter of the first uplink bandwidth part, and random access channel parameters of a random access channel resource. A preamble is transmitted via the random access channel resource on the first uplink bandwidth part. A random access radio network temporary identifier (RA-RNTI) is determined based on the bandwidth part configuration parameter and one or more of the random access channel parameters. A downlink control channel is monitored for a downlink control information addressed to the RA-RNTI in response to the determining. The downlink control information indicates a downlink radio resource of a random access response is received. The random access response is received via the downlink radio resource in response to the downlink control information.

  • Patent number: 10739841
    Abstract: Bandwidth for information transfers between devices is dynamically changed to accommodate transitions between power modes employed in a system. The bandwidth is changed by selectively enabling and disabling individual control links and data links that carry the information. During a highest bandwidth mode for the system, all of the data and control links are enabled to provide maximum information throughout. During one or more lower bandwidth modes for the system, at least one data link and/or at least one control link is disabled to reduce the power consumption of the devices. At least one data link and at least one control link remain enabled during each low bandwidth mode. For these links, the same signaling rate is used for both bandwidth modes to reduce latency that would otherwise be caused by changing signaling rates. Also, calibration information is generated for disabled links so that these links may be quickly brought back into service.

  • Patent number: 10728080
    Abstract: Methods, systems, and devices for wireless communication are described. A transmitter, such as a user equipment and/or a base station, may perform polar coding to encode bits. The polar coding may be associated with a plurality of component channels associated with a polar code length. The transmitter may interleave the encoded bits. The transmitter may map the interleaved encoded bits to a modulation symbol. The interleaving and mapping of each encoded bit may be based on an asymmetry of a polar code construction. The transmitter may transmit the interleaved encoded bits based on the mapping.

  • Patent number: 10721027
    Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

  • Patent number: 10716116
    Abstract: The embodiments herein relate to a method in a base station (603) for communicating with a user equipment (605) in the communication network (600). The base station (603) is configured to communicate with the user equipment (605) according to a selectable of at least two user equipment categories. Based on information about a selected user equipment category, the base station (603) determines a first number of maximum transmission layers supported by the base station (603). The base station (603) communicates with the user equipment (605) according to up to the determined first number of maximum transmission layers and according to the selected user equipment category.

  • Patent number: 10715284
    Abstract: The invention relates to a method of requesting retransmission of a lost data packet initially transmitted by a multicast transmitter in a network, the multicast transmitted multicasting data packets in the network, said method being carried out by a first multicast receiver and comprising the following steps: upon detection (201) of a loss of at least one data packet on a data link between the multicast transmitter and the first multicast receiver, setting (206) a timer value and arming (207) a timer; upon detection (208) that the timer reaches the set timer value, sending (209) a non-acknowledgment message to the multicast transmitter via an uplink control link, said non-acknowledgment message comprising an identifier of at least one lost data packet, if it has not been previously retransmitted by the multicast transmitter.

  • Patent number: 10716132
    Abstract: A wireless communication base station device, terminal device, and method have reduced signaling while maintaining high scheduling gain. A judgment unit pre-stores a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality, and the maximum value for the number of clusters that is output by the judgment unit, a scheduling unit schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.

    Abstract: A device, system and method are provided for wirelessly transmitting a sequence of video packets containing video data for one or more video frames. An importance metric associated with a priority of transmitting each individual packet in the sequence of video packets is independently computed, a retry limit or packet lifetime for each individual video packet in the sequence of video packets is independently determined based on the importance metric, and each video packet in the sequence of video packets is attempted to be transmitted. If the transmission attempt for an individual video packet in the sequence fails, the transmission attempt is repeated for up to the retry limit or the packet lifetime independently determined for the individual packet or until a successful transmission is achieved, whichever occurs first.
