Abstract: A method and apparatus for dimensioning a plurality of base stations to be installed within an area such as an enterprise location or a floor space within an enterprise location of an enterprise network. The wireless communication network is a spectrum-controlled network such as a Citizen's Broadband Radio Service (CBRS) network that is spectrum-controlled by a spectrum access server, and the base stations may comprise CBRS devices (CBSDs). A method of allocating radio bands among the base stations is described that effectively utilizes the available spectrum. A domain proxy is connected to communicate with the spectrum access server on behalf of the CBSDs, to inquire regarding spectrum and request spectrum grant.

Abstract: Methods and apparatus are disclosed for determining spectrum availability within a radio band managed by a Spectrum Management Entity (SME), and allocating available spectrum to Base Station/Access Points (BS/APs) of an Enterprise Network (EN). The EN includes a domain proxy that sends a registration request to the SME indicating a maximum EIRP for the BS/APs. After receiving registration, the Domain Proxy sends a spectrum inquiry and receives a response specifying available spectrum. If less than the entire requested spectrum is available, then the maximum EIRP indication is reduced, and a next iteration is performed re-registering the BS/APs and requesting spectrum. Iterations are repeated until the entire requested spectrum is available, and then spectrum is allocated to the BS/APs. Each iteration of channel availability is stored, and channels are allocated utilizing a Self-Organizing Network (SON) technique responsive to the stored channel availability. The EN may comprise a CBRS Network.

Abstract: Systems and methods for mitigation of cross channel interference are disclosed in which the TDD configuration of a potential cross channel interference source is detected by received signals within the network with which the source interferes. The TDD configuration is then used to synchronize the transmissions from the network with which the source interferes to reduce the interference. In addition, interference is mitigated by providing adaptive guard bands based on results of a radio frequency environmental survey and/or coaxing an interfering user to another channel. Sub-channels can be assigned based on the results of the radio frequency environmental survey and Quality of Service requirements for traffic flows.

Abstract: Wireless transmit/receive units (WTRUs) may include unmanned aerial vehicles (UAVs). The WTRUs/UAVs may cooperate to exchange channel busy ratio (CBR) and/or CBR statistics of one or more (e.g., all) the carriers that the WTRUs/UAVs monitors with each other for carrier selection/carrier reselection. A network may provide one or more inputs on carrier selection. For example, a network may provide one or more inputs on carrier selection based on the congestion that the network infers (e.g., through the CBR measurements reported by the WTRUs/UAVs and/or through its own measurements). MAC/PHY layers may be configured to perform transmit adaptation during PDCP packet duplication. For example, the carrier aggregation capability of receivers may be considered to adapt the number of transmissions per carrier. Based on the carrier aggregation capability of the receivers, the number of transmissions at one or more (e.g., every) carriers may be optimized jointly across carriers.

Abstract: A method and apparatus for handling channel termination in a spectrum-controlled wireless communication network and bringing power back up to resume normal operation. The network includes Base Stations/Access Points (BS/APs) in communication with a number of User Equipment devices (UEs) within the coverage area over wireless channels. When a channel termination order is received, the network identifies at least one BS/AP communicating on the prohibited channel and designates at least one BS/AP not transmitting on the prohibited channel which is allowed to increase transmission power. The system gradually reduces power on the impacted BS/AP and gradually increases power on the designated BS/AP to induce handoff to provide a smooth transition and avoid service interruptions to connected UEs. In one embodiment the wireless network is a Citizen's Broadband Radio Service (CBRS) network, and the BS/APs are located at an enterprise location and form part of an enterprise network.

Abstract: A method and apparatus for deploying Base Stations/Access Points (BS/APs) in an enterprise wireless communications network. The method is useful to deploy BS/APs in a managed radio communication environment to mitigate and prevent interference between competing transmitters in the area. The BS/APs may comprise Citizens Broadband radio Service Devices (CBSDs) deployed in 4G and 5G enterprise communications networks operating under FCC rules relating to Citizens Broadband Radio Service (CBRS). Spectrum may be managed by a Spectrum Management Entity (SME). In order to pre-register BS/APs prior to deployment, location coordinates corresponding to an enterprise address may be used. A domain proxy (DP) may request registration, obtain a spectrum grant, and maintain the grant.

Abstract: Methods and apparatuses are described herein for providing Hybrid Automatic Repeat Request (HARQ) techniques for a non-terrestrial network. For example, a wireless transmit/receive unit (WTRU) may transmit, to a satellite base station (BS), uplink (UL) feedback that includes configuration information for redundancy versions (RVs) and cross redundancy versions (cRVs). The WTRU may receive one or more first RVs associated with a first transport block (TB). The WTRU may receive one or more second RVs associated with a second TB and at least one cross redundancy version (cRV) associated with the first TB and second TB. The cRV may include parity bits generated from both the first TB and second TB. If at least one of the first TB or the second TB is unsuccessfully decoded, the WTRU may decode the first TB and second TB jointly based on the at least one cRV.

Abstract: An unmanned aerial vehicle (UAV) may detect a risk of collision with one or more objects in an airspace serviced by a mobile edge computing (MEC) node. The MEC node may provide an edge detect and avoid (edge-DAA) function for use in the airspace. The UAV may determine a first resolution advisory (RA) to be acted on in order to avoid the collision with the one or more objects based on a local DAA function within the UAV. The UAV may receive, from the MEC node, a second RA to be acted on in order to avoid the collision with the one or more objects based on the edge-DAA function. If the second RA can be acted onto avoid the collision with the one or more objects, the UAV may act on the second RA and may send a message to the MEC node with an acknowledgement.

Abstract: 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.

Abstract: A wireless transmit/receive unit (WTRU) may receive a downlink communication from a network over a first interface transmitted to one or more WTRUs in a group of WTRUs. The WTRU may determine an access class of the WTRU based on a packet loss percentage of the downlink communication. The access class may be associated with a contention window for accessing a second interface. The WTRU may transmit packet loss information to the one or more WTRUs over the second interface in the contention window. The WTRU may receive packet loss feedback from the one or more WTRUs over the second interface. The WTRU may determine that the access class of the WTRU is a highest class of the one or more WTRUs. The WTRU may transmit a single groupcast negative acknowledgement (gNACK) to the network on behalf of the one or more WTRUs over the first interface.

The processor may be configured to receive a message from the other vehicle that is indicative of one or more conflicts and to determine a list that includes the vehicle(s) associated with the one or more conflicts. The processor may be configured to determine a resolution that addresses the conflict(s) associated with the list.

Abstract: An unmanned aerial system (UAS) may execute a mission planned by a UAS traffic management (UTM) system. The UAS may receive a mission planning response message from the UTM that includes a mission route for the UAS to navigate and a configuration of one or more trigger events. The mission route may be made up of a sequence of waypoints in an airspace. Each of the waypoints may be configured with a dynamic path conforming profile (PCP) a dynamic required navigation performance (RNP) value. The UAS may monitor at least the RNP value in one or more time intervals to determine if a trigger event occurs. The UAS may transmit a path conformance status report to the UTM upon determining that a trigger event of the one or more trigger events occurred. The path conformance status report may indicate conformance to one or more parameters specified in the PCP.
