Abstract: Systems, methods, apparatuses, and computer program products for configuring a dual-mode SL LCH with simultaneous mode 1 and mode 2 transmission are provided. One method may include configuring one or more dual-mode sidelink (SL) logical channels (LCHs) to at least one user equipment to enable simultaneous sidelink mode 1 and sidelink mode 2 transmission. The method may also include receiving, from the at least one user equipment, at least one sidelink (SL) buffer status report (BSR) that may optionally comprise buffer status for one or more of the configured dual-mode logical channels (LCHs) according to a network configuration, and transmitting, to the at least one user equipment, a resource allocation that can be applied for the dual-mode logical channels (LCHs) according to the network configuration.

Abstract: It is provided a method comprising: indicating that a HARQ process is initiated for transmitting at least a first HARQ message comprising an inquiry as the first message of the HARQ process, wherein the inquiry inquires whether a relay terminal for relaying a communication of a transmitting terminal is available; transmitting the first HARQ message using the HARQ process; monitoring whether a HARQ feedback is received from at least one relay terminal in response to the first HARQ message according to the HARQ process; deciding that the at least one relay terminal is available if the HARQ feedback is received from the at least one relay terminal; deciding that the at least one relay terminal is not available if the HARQ feedback is not received from the at least one relay terminal.

Abstract: Systems, methods, apparatuses, and computer program products for physical sidelink transmission for sidelink inter-user equipment resource allocation. A method may include receiving at a first user equipment based on a decision of a second user equipment, a resource allocation from the second user equipment. The method may also include determining whether to transmit a sidelink control information associated to a transmission using the resource allocation over a control channel. The method may further include performing a transmission using the resource allocation.

Abstract: Apparatus and method for communication are provided. One or more link identifiers used by a first terminal device are obtained. Information on communication of another terminal device with the first terminal device based on the obtained one or more link identifiers is obtained. Based on the obtained information, it is determined, that the first terminal device is active for communication and transmission to the first terminal device performed based on the determination.

Abstract: Various example embodiments relate to providing feedback with an adaptive acknowledgement mode. A device may transmit an allocation of transmission resource(s) associated with a second acknowledgement mode. The second acknowledgement mode may include transmission of a positive acknowledgement and a negative acknowledgement. Another device may detect a condition to switch to a first acknowledgement mode including transmission of the negative acknowledgement and not transmission of the positive acknowledgement. The other device may transmit an indication of a switch to the first acknowledgement mode. Apparatuses, methods, and computer programs are disclosed.

Abstract: When there is a role switch between a first apparatus acting as a relay node towards a wireless network for one or more second apparatuses acting as remote nodes a relay context used by the first apparatus towards the wireless network is communicated to a second apparatus using sidelink communication. After that the first apparatus starts to act as a remote node and the second apparatus starts to act as a relay node using the relay context. Use of the same relay context makes the role switch transparent to the wireless network.

Abstract: According to an aspect, there is provided a terminal device comprising means for performing the following. The terminal device transmits a tethering request for setting up a tethering cell over at least one communications network to at least one tethering terminal device capable of setting up a tethering cell. Then, the terminal device performs tethering cell discovery for discovering tethering cells set up by any of said at least one tethering terminal device. In response to discovering a tethering cell provided by a tethering terminal device of said at least one tethering terminal device, the terminal device accesses the tethering cell.
