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.

Devices and methods of signaling for resource selection and reservation in sidelink transmission

Methods and systems for physical layer network coding based on two-dimensional (2D) joint coding are described. In some methods, first and second packets are obtained. A set of one or more cross-packet check blocks is generated, where each cross-packet check block is generated based on a set of cross-packet bits including at least one bit from each of the first and second packets. At least one cross-packet check block is transmitted to a first communication node.

Methods and systems for network coding using cross-packet check blocks

A method for uplink transmission by a UE includes obtaining information regarding a plurality of power control sets each having a plurality of power control parameters, wherein a value of at least one parameter in a first power control set is different from a value of the at least one parameter in a second power control set; obtaining information associating at least one of the power control sets with at least one operational property of the UE; and when at least one of the operational properties is in effect on the UE, transmitting a PUSCH using the parameters of the power control set associated with the at least one operational property in effect.

Method of power control for uplink transmission

Provided is a method in a user equipment, the method comprising: as part of a HARQ process having a HARQ process ID, transmitting an initial grant-free transmission and K−1 repetitions, where K>=2. A pre-defined mapping of the HARQ process ID to at least one resource available for grant-free transmission is a function of K.

Configuration, indication and ACK/NACK for multiple HARQ grant-free transmission

Methods and systems for two-dimensional (2D) coding are described for broadcast, multicast or groupcast applications. Two or more information code blocks (CBs) are transmitted to a plurality of intended receiving nodes. One or more cross-CB check blocks are generated, each cross-CB check block being generated based on a set of cross-CB bits, the set of cross-CB bits including at least one bit selected from each of at least two of the information CBs. At least one cross-CB check block is transmitted to at least one of the intended receiving nodes.

Methods and apparatuses for broadcast multicast or groupcast transmission using vertical check blocks

A method of data communication, comprising: obtaining resource unit information associated with a physical uplink channel; determining an identifier at least in part based on the resource unit information; and using the identifier for transmission of a physical uplink shared channel (PUSCH). Also, a method of data communication, comprising: obtaining resource unit information associated with a physical uplink channel; determining an identifier at least in part based on the resource unit information; and using the identifier for transmission of a physical downlink channel. Also, an apparatus comprising a processor and an RF communication unit, the processor configured to obtain resource unit information associated with a physical uplink channel; determine an identifier at least in part based on the resource unit information; and use the identifier for transmission of a physical uplink shared channel (PUSCH) or a physical downlink channel.

Methods and apparatus for determining network identifier for use by user equipment

A method and apparatus to configure grant-free transmission resources are provided. At least two configuration options can co-exist for configuring the grant-free transmission resources. The base station may explicitly or implicitly notify a user equipment which option is selected for grant-free transmission by that user equipment.

Methods and systems for resource configuration of wireless communication systems

A method for transmitting data over a SL data channel wherein a transmit UE and a receive UE are each semi-statically provided with a CG configuration such that a CG configuration indication does not have to be transmitted in association with each individual data transmission during a duration that the CG configuration is applied.

Sidelink configured grant resource configuration and signalling

A method that includes sensing, by a first user equipment (UE), a signal transmitted by a second UE indicating a resource reservation for a shared channel for a sidelink (SL) transmission by the second UE and a priority associated with the SL transmission; determining, by the first UE, a threshold based on a type of the SL transmission and the priority; and selecting, by the first UE, a resource in the shared channel to use for a SL transmission by the first UE based on the threshold.

Sensing and resource selection based on priorities for sidelink transmissions

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.

Transmission pattern indication and selection for sidelink grant free transmission

Methods are disclosed that enable a user equipment (UE) to receive cell specific, UE specific and, in some embodiments, Physical Uplink Shared Channel (PUSCH) specific parameters from a network side component, such as a transmit/receive point, and use that information to set at least one PUSCH transmit power when transmitting to the network side.

Systems and method of power control for uplink transmissions

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.

Methods and apparatus for sidelink communications and resource allocation

A user equipment (UE) receives a message that indicates a sidelink (SL) communication resource configuration to be used by the UE for communicating SL control information and SL data between the UE and another UE. The UE transmits SL control information according to the SL communication resource configuration, and transmits SL data according to the SL communication resource configuration. The SL control information and the SL data are transmitted by the UE without the UE receiving, in a downlink control information (DCI), a grant of communication resources.

In a wireless communication system, a grant-free uplink transmission is an uplink transmission sent from a user equipment (UE) to a base station that does not need a dynamic and explicit scheduling grant from the base station. Systems and methods are disclosed for performing hybrid automatic repeat request (HARQ) for grant-free uplink transmissions. Signaling relating to the ACK/NACK for the HARQ, as well as signaling relating to configuring the UE for grant-free uplink transmission, is also disclosed.
