The assistance information comprises a plurality of elements indicative of characteristics of the sidelink communications and at least one of the plurality of elements comprises an indication of the discontinuous reception mode of the receiving user equipment.

Allocating resources for direct user equipment communication

Apparatus and method to perform receiving from a network node of a first mobile network of more than one mobile network of a communication network, by a user equipment of the first mobile network, an indication () of an approaching coverage limit for a coverage area associated with a link between the first public land mobile network and the user equipment wherein the user equipment includes a multi subscriber identity module, and wherein a first subscriber identity module of the multi subscriber module is connected to a network node associated with the first mobile network; and based on the receiving, performing pro-active preparation for causing () a second subscriber identity module of the multi subscriber identity module of the user equipment to enable pro-active preparation of switching to a second mobile network of the more than one mobile network in response to an upcoming failure of the link between the user equipment and the first mobile network based on the approaching coverage limit of the coverage area. Further, there is determining, by a network node of a first mobile network of more than one mobile network of a communication network, an approaching coverage limit for a coverage area associated with a link between the first mobile network and a user equipment, wherein the user equipment includes a multi subscriber identity module and wherein a first subscriber identity module of the multi subscriber module is connected to a network node associated with the first public land mobile network; and based on determining, sending towards the user equipment information including an indication to perform pro-active preparation for causing a second subscriber identity module of the multi subscriber identity module of the user equipment to enable pro-active preparation for switching by the second subscriber identity module to a second mobile network of the more than one mobile network in response to an upcoming failure of the link between the user equipment and the first mobile network based on the approaching coverage limit of the coverage area.

Enhanced service continuity utilizing MUSIM

A method including transmitting, by a third user device, to one or more second user devices, a request message for requesting a handover of a sidelink positioning session established between the third user device and a first user device; receiving, by the third user device, from the one or more second user devices, one or more response messages to the request message; selecting, by the third user device, at least one second user device of the one or more second user devices; and transmitting, by the third user device, to the at least one second user device, at least one configuration for performing one or more handovers of the sidelink positioning session from the third user device to the at least one second user device for the first user device.

Handover of sidelink positioning session

There is provided an apparatus for a sidelink, SL, communication comprising means for transmitting a transport block, TB, via the SL communication, means for receiving a feedback in response to the transmitted TB, means for storing information contained in the transmitted TB upon receiving said feedback, means for receiving a status report comprising information associated with the TB, and means for comparing said information contained in the status report with said stored information contained in the transmitted TB in order to identify an attacker based on discrepancy between said information contained in the status report and said stored information contained in the transmitted TB.

Detecting sidelink attacks

Systems, methods, apparatuses, and computer program products for new radio (NR) sidelink relay of small data transmissions (SDT) are provided. One method may include determining whether conditions to use SDT via at least one relay user equipment are met. When it is determined that the conditions to use the SDT are met, the method may include transmitting a SDT relaying request comprising a SDT payload to the at least one relay user equipment. The method may also include receiving a SDT response, from the at least one relay user equipment, based on how the SDT relaying request is transmitted.

Radio sidelink relay of small data transmissions

Systems, methods, apparatuses, and computer program products for sidelink group coordination for group-specific synchronization reference are provided. For example, a method can include determining, by a user equipment, whether a first condition is met for coordination on group synchronization reference for a group of user equipment. The method can also include determining, by the user equipment, whether a second condition is met to act as group synchronization reference user equipment for the group.
