摘要： Methods, architectures, apparatuses and systems directed to active sensing in a wireless communications system (WCS) are provided. A method may include receiving, from a network element, information indicating an activation of a first of a plurality of sensing configurations, wherein the first sensing configuration and a second of a plurality of sensing configurations may include information indicating first and second resources of the WCS; transmitting a first sensing signal according to the first sensing configuration and using the first resources; performing first measurements related to the first sensing signal; transmitting, to the network element, information indicating a change from the first sensing configuration to the second configuration; receiving, from the network element, information indicating an acknowledgment of the change in the sensing configurations; transmitting a second sensing signal according to the second sensing configuration and using the second resources; and performing second measurements related to the second sensing signal.

摘要： A method to reserve a directional channel, such as in an unlicensed spectrum for instance, is disclosed. In an example embodiment, the method may be performed by a receiving node, such as a user equipment (UE) for instance. In such method, the receiving node may receive an enhanced directional transmit request message from a transmitting node and transmit an enhanced directional transmit confirmation message using one or more first beams, with at least one first beam being directed in a first direction towards the transmitting node. Further, the receiving node may transmit at least one additional enhanced directional transmit confirmation message using one or more second beams, with at least one second beam being directed in a second direction towards a potentially interfering node. In the method, the second direction is a different direction than the first direction.

摘要： Systems, methods, and instrumentalities are disclosed for Random Access Channel (RACH) procedures in unlicensed spectrum. A wireless transmit/receive unit (WTRU) may monitor for a random access response (RAR) or a reference signal (RS), e.g. in an RAR window. The WTRU may determine whether an RS has been received a threshold amount of times, e.g. if an RAR is not received. The WTRU may continue to monitor for an RAR or an RS, e.g. if the RS has not been received a threshold amount of times and the RAR window is not at a maximum RAR window size.

摘要： Methods, systems, and devices for addressing timing advance (TA) in non-terrestrial network communication is disclosed herein. A wireless transmit and receive unit (WTRU) may receive system information from a base station attached to an airborne or spaceborne vehicle that indicates a physical random access channel (PRACH) resource. The WTRU may determine a timing offset based on a plurality of information, such as the location information and the system information. The WTRU may transmit a preamble using the timing offset via the PRACH resource. The base station may receive the preamble and send a random access response (RAR) that includes, for example, a TA command. The WTRU may receive the RAR including the TA command and combine the timing offset with the TA command to determine an actual TA, after which the WTRU may use the actual TA for uplink transmissions.

摘要： A WTRU may track parameters associated with the WTRU or target WTRUs. The parameters may be associated with positioning and/or sidelink communications. The WTRU may receive a configuration for transmission of reference signals to target WTRUs. The WTRU may transmit one or more reference signals on one or more configured sidelink resources. The WTRU may receive respective measurement report(s) from respective target WTRU(s) (e.g., a target WTRU may receive a reference signal transmitted by the WTRU and send an associated measurement report). The WTRU may be configured to send the received target WTRU measurement(s) to the network entity. The WTRU may send each of the received measurements. The WTRU may send the received measurement(s) if condition(s) are satisfied. For example, if a first measurement associated with a first measurement report from a first target WTRU exceeds a first threshold, the WTRU may send the first measurement to the network entity.
