Abstract: 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. The method can further include transmitting, by the user equipment, a group synchronization reference signal when determined to act as the group synchronization reference user equipment. The method can additionally include performing, by the user equipment, a reduced synchronization search when determined not to act as the group synchronization reference user equipment.

Abstract: Systems, methods, apparatuses, and computer program products for neighbor cell measurement based timing advance validation. A method may include receiving a network configuration comprising a timing advance command from a network element. The method may also include acquiring at least measurement data of a serving cell relative to a first set of neighbor cells at a first time instance, and measurement data of the serving cell relative to a second set of neighbor cells at a second time instance according to the network configuration. The method may further include performing a timing advance validity check using at least the acquired measurement data from the first time instance and the second time instance. Further, the method may include performing data transmission based on a result of the timing advance validity check.

Abstract: Systems, methods, apparatuses, and computer program products for identifier (ID)-based inter-user equipment (UE) resource allocation (RA). A method may include receiving, at a first user equipment, a list of identifiers used for communication between a second user equipment and its one or more peer user equipment (UEs). The method may also include obtaining information of a first resource reserved for communication between the second user equipment and its one or more peer user equipment, based on the received list of identifiers. The method may further include determining a second resource for the second user equipment based on the obtained information of the first resource. In addition, the method may include allocating the second resource for sidelink communication of the second user equipment.

Abstract: In accordance with some example embodiments, an apparatus may comprise at least one processor and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to transmit at least one parameter configuration of a random access channel procedure to a user equipment; receive at least one physical uplink shared channel part of a first random access channel message using at least one transmitter beam configuration; upon detection of at least one preamble part of the first random access channel message, decode the physical uplink shared channel part of the first random access channel message and perform at least one channel quality measurement on at least one demodulation reference signal sequence transmitted on a number of selected transmitter beam configurations.
