    Abstract: Embodiments of this disclosure improve the reliability of blind decoding when beamforming is used by having a user equipment (UE) receive a single downlink control information (DCI) message with different transmission and/or reception parameters. In some embodiments, a UE receives more than one set of configuration parameters, where any two sets of configuration parameters out of the more than one set of configuration parameters have at least one different parameter. The UE may receive two sets of configuration parameters each having a different transmission modes, but the same search space type. Additional examples are also provided.

    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.

    Abstract: Systems and methods for early termination of feedback in respect of sidelink transmissions are provided. A first UE transmits at least one sidelink (SL) transmission of a first set of SL transmissions to a second UE, the first set of SL transmissions comprising an initial SL transmission and a set number of SL retransmissions. If no ACK is received, then the first UE transmits the set number of retransmissions. On the other hand, if an ACK is received, then the first UE transmits fewer than the set number of SL retransmissions when an ACK is received from the second UE before the set number of SL retransmissions has been completed. By transmitting fewer than all of the set number of SL retransmissions, resources can be freed up for other purposes. The approach may be used for SL configured grant transmission.

    Abstract: With sidelink reservation signals sent together with the sidelink data, there is the possibility of interference with other sidelink signals. In order to address this, systems and methods are provided in which a first UE transmits a reservation signal to indicate at least one time-frequency resource for transmitting sidelink data. Following this, the first UE transmits at least one sidelink data transmission to a second UE using the at least one time-frequency resource indicated by the reservation signal. The reservation signal is transmitted before the at least one sidelink data transmission signal so that a third UE may detect the reservation signal and use the reservation signal to avoid using the at least one time-frequency resource indicated in the reservation signal.

    Abstract: Methods and systems are provided in which a UE transmits sidelink (SL) control information comprising a scheduling assignment (SA) indicating an SL transmission resource for a SL data transmission to a target UE. The SL transmission resource is based on one or more occupied SL resources identified by the UE and the SL transmission resource includes resources for an initial transmission and one or more retransmissions. The UE then transmits the SL data transmission using the SL transmission resource according to the transmitted SL control information. This is done without receiving, in a downlink control information (DCI), a grant of communication resources.
