Example embodiments of the present disclosure relate to transmission of control information associated with sidelink positioning reference signal. In an example method, a first terminal device in a radio access network comprises at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the first terminal device to: transmit, to a second terminal device in the radio access network, control information associated with a sidelink (SL) positioning reference signal (PRS) during a SL positioning session for positioning of the second terminal device, using a resource for the control information in a Physical Sidelink Feedback Channel (PSFCH) symbol or in at least one symbol dedicated for the control information. In this way, the first terminal device can efficiently transmit control information to the second terminal device with backward compatibility.

Transmission of control information associated with sidelink positioning reference signal

Embodiments of the present disclosure provide for selecting a first candidate beam for communication with a first transmitter (Tx) user equipment (UE) and a second candidate beam for communication with a second Tx UE; determining a first radio resource expected to be used by the first Tx UE for a first radio transmission to a receiver UE and a second radio resource expected to be used by the second Tx UE for a second radio transmission to the receiver UE; determining that the first radio resource overlaps in time with the second radio resource, and that the first candidate beam does not match the second candidate beam; and determining whether to: receive the first radio transmission using the first candidate beam, receive the second radio transmission using the second candidate beam, or receive the first radio transmission and the second radio transmission using a third candidate beam.

Enhanced beam selection for NR sidelink communication in FR2

Systems, methods, apparatuses, and computer program products for user equipment behavior with respect to hybrid automatic repeat request retransmission in new radio sidelink co-existence scenarios with another technology are provided. For example, a method can include enabling, for a receiving user equipment, hybrid automatic repeat request negative acknowledgement only feedback. The method can also include first determining whether to condition negative feedback on at least one first condition, or second determining whether negative feedback is conditioned on at least one second condition. The method can further include third determining whether to retransmit a message according to hybrid automatic repeat request according to results of the first determining or the second determining. The method can additionally include communicating with the receiving user equipment based on a result of the third determining.

User equipment behavior of hybrid automatic repeat request retransmission in new radio sidelink co-existence scenario with other technology

A method for positioning in a sidelink communication. The method includes detecting, by an anchor component, a presence of at least one user equipment; and activating, by the anchor component, a transmission of a positioning reference signal to the user equipment responsive to the detected presence of the at least one user equipment.

Transmission of positioning reference signals for sidelink communications

A method and an apparatus for a second user equipment, that causes the apparatus to perform: determining whether a synchronization signal has been received during a first set of synchronization resources; and when it is determined the synchronization signal was received, determining that the apparatus is allowed to use communication resources during a second set of synchronization resources for a first sidelink communication; and when it is determined the synchronization was not received, abstaining from using the communication resources during the second set of synchronization resources for a first sidelink communication; and monitoring the second set of synchronization resources for a synchronization signal.

Apparatus and method

Example embodiments of the present disclosure relate to a solution of transmitting sidelink (SL) feedback information on non-contiguous resource sets. In this solution, in accordance with a determination that a plurality of feedback transmission occasions for sidelink transmissions are mapped on non-contiguous resource sets, an apparatus determines a group of contiguous resource sets mapped with a subset of the plurality of feedback transmission occasions; and transmits feedback information on the group of contiguous resource sets.

Sidelink feedback information

There is provided an apparatus, said apparatus comprising means for providing first control information using a first control channel and at least second control information using a second control channel, wherein the first control information comprises at least an indication of resource reservation for an associated data channel and the second control information comprises at least transmission format information for the associated data channel, wherein the associated data channel comprises periodic or aperiodic data traffic.

Control channel structure design to support V2X traffic

A user equipment includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the user equipment to: select radio resources for a first sidelink transmission to a first user equipment based on sidelink control information from a second user equipment, the sidelink control information including at least beam information for a second sidelink transmission by the second user equipment; and perform the first sidelink transmission to the first user equipment on the selected radio resources.

Sidelink beam information sensing and transmission

An SL UE that detects a resource conflict associated with a transmitting UE may be able to indicate this resource conflict by transmitting inter-UE coordination information over a PSFCH resource determined based on a group member ID of the transmitting UE. This may be different from transmitting HARQ feedback via a PSFCH resource determined based on a group member ID of the detecting UE.

Collision indication for sidelink groupcast with HARQ option 2

A user device may receive from a base station, information indicating that support for a receive limited user device is enabled based on a presence of a threshold number of receive limited user devices within a range of a cell of the base station. A receive limited user device is a user device that is unable to receive a transmission that was transmitted based on one or more communication capabilities of a full set of communication capabilities. The user device may select, in response to receiving the information, one or more communication capabilities to support a receive limited user device. The user device may transmit information using the selected one or more communication capabilities.

Support for receive-limited user equipment in wireless environments

Embodiments of the present disclosure provide a communication method and apparatus. For example, at a first device, a resource for data transmission is randomly selected, and the resource is used to transmit data. In addition, the first device sends, to a second device, an indication that the first device will continue to use the resource for transmitting further data. A corresponding apparatus is further disclosed in the present disclosure.

Method and apparatus for managing resources in communication system

The method includes determining a time interval during which at least one other user equipment is to transmit a data transmission; generating a scheduling signal indicative of the data transmission; and transmitting the scheduling signal during the determined time interval.
