Abstract: Systems and methods for sidelink configuration are provided. A transmitting user equipment (UE) transmits configuration parameters relating to a sidelink transmission between the UE and a second UE via higher-layer signalling and then transmits the sidelink transmission to the second UE. The higher layer signalling is a layer above the sidelink transmission. The parameters may include feedback channel parameters or parameters for sidelink reference signal transmission by the second UE. The parameters may be selected by the transmitting UE, or they may be received initially from the network. The parameters may be part of a sidelink configured grant configuration (SL CG) signalled to the second UE. The sidelink transmission may be a configured-grant transmission to the second UE according to the SL CG configuration. The higher layer signalling may be PC5 signalling or RRC signaling.

Abstract: A method includes: a terminal device may determine, based on a type of downlink control information DCI, whether data scheduled by using the DCI exists on a preempted time-frequency resource, to determine whether the data transmitted on the preempted time-frequency resource needs to participate in data decoding.

Abstract: A network may have data to send to a target UE in a D2D group. It is desired to use the D2D group to help facilitate the downlink transmission of the data to the target UE. In one embodiment, control information in a downlink control channel is masked with a D2D group ID. UEs in the D2D group use the group ID to unmask the control information. The control information is used to locate and decode data in the downlink data channel that is meant for the target UE. Other UEs in the D2D group may forward the decoded data (or a re-encoded version of the decoded data or other information) to the target UE over a D2D channel.

Abstract: Virtualized group-wise communications between a wireless network and a plurality of user equipments (UEs) are supported using UE cooperation. UE cooperation includes receiving, at a cooperating UE (CUE), downlink information from the wireless network destined for a target UE (TUE) and associated with a group identifier (ID). The group ID indicates a virtual multi-point (ViMP) node that includes the TUE and the CUE. The UE cooperation also includes sending the downlink information to the TUE. The UE or UE component can have a processor configured to forward between the wireless network and a TUE at least some information that is associated with a group ID indicating a ViMP node that groups the TUE and the UE.

Abstract: Method and devices are provided for wireless communication. A method involves obtaining, by a receive user equipment (UE), configuration information relating to a sidelink transmission between the first UE and a second UE, the configuration information for indicating to the first UE that the sidelink transmission is not associated with any corresponding sidelink control information (SCI). A further step involves receiving, by the receive UE, the sidelink transmission from the second UE using time and frequency resources indicated by the configuration information. Another method involves obtaining, by a transmit UE, configuration information relating to a sidelink transmission between the first UE and a second UE, the configuration information for indicating to the first UE that the sidelink transmission is not associated with any corresponding SCI and transmitting, by the first UE, the sidelink transmission to the second UE using time and frequency resources indicated by the configuration information.

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: 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).

Abstract: A system and method for multiplexing traffic. A wireless device such as a user equipment (UE) may receive a first signal over first resources assigned to carry a first downlink transmission from a base station, and receive a first downlink control indication (DCI) message from the base station. The first DCI message may include a pre-emption region (PR) indication and a PR bitmap, and the PR indication may indicate a location of a time-frequency region. The PR bitmap may include bits associated with different portions of the time-frequency region, and each of the bits in the PR bitmap may indicate whether a preemptive downlink transmission is present in the corresponding portion of the time-frequency region.

Abstract: Systems and methods of sidelink configuration, and sidelink transmission are provided. A base station transmits, and correspondingly a user equipment (UE) receives, a UE-specific radio resource control (RRC) signal for indicating a resource pool configuration and a sidelink configured grant (SL CG) configuration. The UE transmits a SL CG transmission using the transmission resource indicated by the SL CG configuration, without the UE receiving, in a downlink control information (DCI), a grant of transmission resources.

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: A base station may transmit downlink control information (DCI) scheduling communications between the base station and a UE. The DCI is in a fallback DCI format. Based on whether or not the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE ID of the UE, data transmitted by the base station or by the UE according to the DCI may be scrambled by a sequence that is initialized with a configurable parameter, or initialized with a cell ID.

Abstract: Soft information for achieving interference cancellation in downlink transmissions can be communicated over device-to-device (D2D) links, thereby allowing paired user equipments (UEs) to receive downlink transmissions over the same radio resources. More specifically, paired UEs that receive transmissions over the same time-frequency resources may exchange soft or hard information over D2D links in order to facilitate interference cancellation. The D2D links may be unidirectional or bidirectional, and may be established over in-band or out-of-band resources. Paired UEs may be in the same or different cells, and may receive their respective transmissions from the same or different transmit point. UEs may be paired with one another based on various criteria, e.g., interference cancellation capabilities, scheduling metrics, etc.

Abstract: Systems and methods are disclosed for establishing a device-to-device (D2D) group amongst a plurality of user equipments (UEs). In one embodiment a target UE transmits, using D2D communication, a request message inviting at least one other UE to be part of a D2D group with the target UE. A neighbour UE receives the request message and transmits a report message indicating that the neighbour UE will be part of the D2D group with the target UE. A base station receives the report message and transmits to the target UE and to the neighbour UE a confirmation message indicating that the neighbour UE is in the D2D group with the target UE.

One Physical Downlink Control Channel (PDCCH) for DL control information transmission is assumed to carry at least one assignment or scheduling information block for at least one Physical Downlink Shared Channel (PDSCH) for DL data transmission or for at least one Physical Uplink Shared Channel (PUSCH) for UL data transmission. Embodiments of the present application provide methods of providing configuration information that can be used by a user equipment (UE) to determine transmission mode for the PDSCH and PUSCH as well as information to determine where to monitor for the PDSCH, PUSCH and PUCCH information.

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.

Abstract: A sidelink (SL) configuration for SL communications directly between a communication terminal and another communication terminal is separate from a communication network link configuration for communications with network equipment in some embodiments. An SL configuration, which could be an SL reconfiguration or an SL preconfiguration for use by the communication terminal after the terminal transitions from in coverage to out of coverage, could be transmitted through network/terminal signaling, and detailed examples of such signaling are disclosed herein. An SL configuration could be or include an SL bandwidth part (BWP) configuration and an SL communication resource configuration, such as one or more resource pools, within the SL BWP. An SL configuration that is determined and transmitted by network equipment to one or more terminals could also or instead involve a common or initial SL configuration to be used for SL communications by multiple communication terminals.
