Abstract: An apparatus configured to: determine a reserved resource for a first transmission and a received signal strength associated with the reserved resource; determine, from a set of candidate resources for a second transmission, a candidate resource, wherein the candidate resource at least partially overlaps in time with the reserved resource, wherein the candidate resource does not overlap in frequency with the reserved resource; determine a relative location, in frequency, of the candidate resource with respect to at least one of: the reserved resource, a first carrier frequency associated with the first transmission, or a second carrier frequency associated with the second transmission; and exclude the candidate resource from the set of candidate resources in response to the received signal strength, associated with the reserved resource, being above a resource exclusion threshold, wherein the resource exclusion threshold is based, at least partially, on the relative location of the candidate resource.

Abstract: Apparatus and method for counter measures for attacking messages are provided. Solution comprises communicating (500) with another apparatus utilising sidelink transmissions, monitoring (502) for an attacking sidelink message based on the content or timing of received messages and entering (504) a defensive mode to mitigate the attack when one or more received messages has been detected as attacking sidelink messages.

Abstract: Systems, methods, and apparatuses for sidelink collision avoidance based on sensing, such as PSFCH sensing, are provided. One method may include sensing, by a first UE, a first sidelink feedback transmission from a second UE in a first PSFCH resource, and determining, based on the first PSFCH resource, a first radio resource in which the second UE received a first data transmission from a third UE. The method may also include sensing a second sidelink feedback transmission from the second UE in a second PSFCH resource, determining, based on the second PSFCH resource, a second radio resource in which the second UE received a second data transmission from the third UE, and determining, based on at least one of the determined first radio resource or second radio resource, a third radio resource in which the second UE is expected to receive a third data transmission from the third UE.

Abstract: 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.
