摘要： Embodiments disclosed and described herein provide systems, apparatus and methods by which advanced networks including 5G capable networks and devices can operate to meet standards, while coexisting with non-telecommunication devices that propagate energy at frequencies within bands used by the 5G capable networks and devices. In particular, systems, apparatus and methods disclosed herein mitigate risk of the networks interfering with the propagated energy while maintaining operation of the networks and protecting the networks and devices from the energy.

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： Latency reduction by fast forward (FF) in multi-hop communication device and/or systems is disclosed. Packets may be received and forwarded using a codeword (CW)-based approach with and/or without per-CW CRC. A FF session may have a flow ID and packets may have sequence numbers. Packets targeted for FF may be divided into independently decodable CWs that may be transmitted in the next hop, for example, as soon as the destination is determined without waiting for an entire packet's arrival and/or for CRC verification. Low latency (e.g. FF) traffic may be indicated. CW-based FF may be extensible for an e2e RAN path from a WTRU to the last access node in a RAN. Intermediate metrics, a packet CRC and/or a per-CW CRC may be utilized for data integrity. HARQ and/or CW retransmission procedures may be implemented between network nodes for error handling.

摘要： A wireless transmit receive unit (WTRU) may receive a set of candidate resources, which may be used for transmission. The WTRU may periodically perform CCA on a channel (e.g., before transmitting on the channel). When the channel is determined to be free, the WTRU may determine a resource for transmission from the candidate resources. The resource may be determined based on the time remaining in the time period. For example, when the time remaining in the time period is shorter, the WTRU may determine to transmit on a resource that comprises more frequency resources. The WTRU may determine a Multiple Input Multiple Output (MIMO) scheme based on the number of frequency resources. The WTRU may send a transmission on the resource, which may include a demodulation reference signal (DM-RS). The DM-RS may indicate the resource used from transmission to a receiver of the transmission.

摘要： A method performed by a base station may compromise: receiving RADAR information; sending scheduling information, wherein the scheduling information includes a set of time and frequency resources associated with a physical downlink transmission that avoid RADAR interference, and wherein the set of time and frequency resources is determined based on the RADAR information; and sending the physical downlink transmission using resources based on the set of time and frequency resources.

摘要： Methods and apparatuses for receive (Rx) beam selection are described herein. A wireless transmit/receive unit (WTRU) may be configured to receive, from a base station (BS), configuration information for joint communication and sensing (JCS) reference signals. The configuration information may include resources for reference signal transmission and resources for measurement reporting. The WTRU may be further configured to receive, from the BS, an indication to activate a subset of the resources for JCS reference signal transmission. The WTRU may be further configured to transmit, a plurality of JCS reference signals using the activated subset of resources for reference signal transmission. The WTRU may be further configured to measure, via a plurality of Rx beams, a backscatter power associated with each of the transmitted plurality of JCS reference signals. The WTRU may be further configured to calculate beam blockage statistics based on the measured backscatter power.

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.
