  • Publication number: 20210144750
    Abstract: Methods and systems are provided that facilitate sidelink (SL) retransmission scheduled by the network if a SL transmission of a transport block (TB) is unsuccessful. Signalling is used by the network to send a configured grant of transmission resources available for SL transmissions by the UE that repeat on a periodic basis within each of period. The UE makes SL transmissions during one of the periods by transmitting one or more SL transmissions of at least one transport block using the configured resources. The network can schedule a retransmission by transmitting a downlink control information (DCI) to schedule a SL retransmission of one of the transmitted TB. The UE transmits a SL transmission containing a retransmission of the transport block using resources specified in the DCI. The UE transmits a sidelink control information associated with each SL transmission, containing a HARQ process ID for the SL transmission.

    Abstract: In accordance with embodiments, methods for data communications are disclosed. A device obtains a forward error correction (FEC) encoded bit stream. The device maps the FEC encoded bit stream to produce a set of symbols according to a bit-to-symbol mapping rule. The bit-to-symbol mapping rule comprises a first mapper bit position associated with a first mapper error protection level and a second mapper bit position associated with a second mapper error protection level. The first mapper error protection level is greater than the second mapper error protection level. The device then transmits the set of symbols in the communications system.

  • Publication number: 20210105104
    Abstract: A first user equipment (UE) is configured to receive from a base station a signaling comprising indication of one or more time-frequency resources and an indicator indicating a time gap, and transmit a transport block (TB) to a second UE using the one or more time-frequency resources. For each of the time-frequency resources, the first UE monitors a hybrid automatic repeat request (HARQ) feedback from the second UE, using a physical sidelink feedback channel (PSFCH) resource; and transmits to the base station a HARQ feedback report signal based on the HARQ feedback or absence thereof, in a physical uplink control channel (PUCCH), using a single PUCCH resource determined based on the time gap from a last one of the PSFCH resources.

  • Patent number: 10952031
    Abstract: Methods and devices are provided to enable a cluster of user equipments (UEs) to receive a multicast signal over a first spectrum band and access a second spectrum band as a single virtual entity for device-to-device (D2D) mutual broadcast within the cluster. In an embodiment, a first UE in a cluster receives a multicast signal from a wireless network over the first spectrum band, the multicast signal including downlink information targeted to a second UE in the cluster. The first UE performs in a contention procedure for a transmission opportunity (TXOP) in the second spectrum band in accordance with group listen-before-talk (LBT) parameters configured for the cluster. If the contention procedure has acquired a TXOP in the second spectrum band for the cluster, the first UE sends at least a portion of the downlink information to the second UE over the second spectrum band during the TXOP.

  • Patent number: 10938635
    Abstract: Systems and methods are provided that facilitate multiple switching points within a slot. A slot format indication is conveyed to a user equipment which indicates which symbols within a slot are uplink, downlink or unknown. Some formats feature half-slot switching meaning that a switch from uplink to downlink transmission takes place twice within a slot. Switching on a more frequent basis can deliver improved latency.

  • Publication number: 20210058198
    Abstract: Methods and devices utilizing sidelink transmission between user equipment (UEs) for HARQ retransmission are provided. The sidelink HARQ retransmissions include data from the initial transmission or an outer coded version thereof. HARQ feedback from the targeted receiver of the initial transmission may identify code block groups and/or individual code blocks the target receiver did not successfully decode. A UE that has not successfully decoded an entire transport block, may still cooperate in HARQ retransmission for the targeted receiver of the transport block by retransmitting at least a subset of the code block groups that it was able to successfully decode for the transport block.

  • Publication number: 20210058937
    Abstract: Systems and methods are provided for transmitting and receiving pre-emption indications. The pre-emption indication is transmitted every K symbols or slots, on a group-common physical downlink control channel. The pre-emption indication is in respect of a group of K symbols or slots preceding a symbol or slot containing the group-common pre-emption indication. The group-common pre-emption indication indicates, for the group of K symbols or slots, which resources are pre-empted. The base station schedules resources for first downlink traffic, and transmits the scheduled first downlink traffic subject to pre-emption, and transmits second downlink traffic by pre-empting resources for the first downlink traffic. On the UE side, the UE receives the pre-emption indication. The UE receives its scheduled traffic taking into account the pre-emption indication.

  • Patent number: 10925046
    Abstract: A New Radio (NR) control signal that indicates one or more Long Term Evolution (LTE) network parameters may be transmitted to NR UEs to enable the NR UEs to identify which resources carry LTE signal(s). The NR UEs may then receive one or more NR downlink signals over remaining resources in a set of resources without processing those resources that carry LTE signal(s). The NR downlink signals may have a zero power level, or otherwise be blanked, over resources that carry the LTE signal(s).

  • Patent number: 10925047
    Abstract: When a user equipment (UE) is wirelessly communicating with a network, the wireless channel conditions may sometimes result in a low signal-to-noise ratio (SNR). The low SNR may be a result of the UE having poor geometry, e.g. the UE is at a cell edge. It is desired to increase the reliability of wireless communications in low SNR conditions. In some embodiments, less information may be dynamically signaled in the downlink control information (DCI), thereby allowing for a possibly lower effective coding rate.
