The operations of the two transceiver modules 210 and 230 may be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250 at the same time that the downlink transmitter is coupled to the downlink antenna 212. Conversely, the operations of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250 at the same time that the uplink transmitter is coupled to the uplink antenna 232. In some embodiments, there is close time synchronization with a minimal guard time between changes in duplex direction.
[0037] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via the wireless data communication link 250, and cooperate with a suitably configured RF antenna arrangement 212 / 232 that can support a particular wireless communication protocol and modulation scheme.

[0043] B. Systems and Methods for eliminating sensing interference
[0044] Radio access network (RAN) provides sensing service. There are two basic sensing modes for wireless sensing: mono-static sensing and bi-static sensing. According to the type of devices (UEs or base stations) , the two basic sensing modes can also be subdivided. FIG. 3 illustrates two basic sensing nodes. In mono-static sensing or bi-static sensing, there may be interference between adjacent base stations that exceeds the receiving capacity, as shown in FIG. 4. Base station 1 sends sensing signals and receives reflected or scattered waves of the sensing signals. In FIG. 4, base station 1 senses UAV (unmanned aerial vehicle) flying at low altitudes. When the UAV flies between base station 1 and base station 2, the sensing signal sent by base station 1 will be directly transmitted to base station 2 as shown by the red dashed line in FIG. 4. Because the deployment locations of the base stations are relatively high, in the scenario described in FIG. 4, the wireless signal transmission between base station 1 and base station 2 is usually the LOS path. The LOS path here is almost free space transmission. The calculation formula for free space power is as follows: Pr=Pt+Gt+Gr-32.4-20lg (f) -20lg (d)
[0045] where f is in Giga-Hertz (GHz) and d is in meters (m) .
[0046] The free space receiving power at 4.9 GHz and 26 GHz using a base station transmission power of 53dBm and an antenna gain of 8 dBm as parameters as shown in FIG. 5. When the distance base stations is 700 m, the received power is -34.11 dBm, as shown in the tip of FIG. 5. In actual base stations, the antenna gain of the base station is greater than the above calculation. However, this power may also exceed the maximum receiving power of the base station (the maximum receiving power of the low-frequency base station is -45 dBm) . This situation is harmful to the base station, on the one hand, it will affect the lifetime of the base stations, and on the other hand, it will interfere with the reception of nearby base stations. Aspects of the present disclosure provides a method of solving received power oversaturation or inference, reducing intercell interference and improving the lifespan of devices.
[0047] Embodiment #1: Power control of Mono-static sensing
[0048] In the mobile communication network, BSs 102 have the potential for wireless sensing due to the introduction of technologies such as large bandwidth and multiple antennas and so on. The BSs 102 can provide sensing services while providing communication service for UEs. The BSs 102 may work at 4.9GHz and the distance between BSs 102 may be 700m.
[0049] In networking, each BS 102 that may be sensing and communicating may lead to the problem of receiving power oversaturation. A procedure of solving sensing receiving oversaturation as shown in FIG. 6. When BS 1 sends the sensing signal with high transmission power, and the transmitting beam of BS 1 is directed towards BS 2, the beam may cause receiving power oversaturation at the BS 2.
[0050] BS 2 sends a measurement report about oversaturation to the sensing function (SF) . The measurement result may include at least one of Receiving power oversaturation event (i.e., receiving power oversaturation occurs) , Timestamp. (i.e., time when the receiving power oversaturation event occurs) , Cell ID (i.e., identification of the cell where the receiving power oversaturation event occurs) , Antenna Port. (i.e., antenna port where the receiving power oversaturation event occurs) , and Potential interference source list (i.e., ID of potential interference source) . In some embodiments, the SF sends a recommendation message to BS 1 to recommend the new sensing resource configuration. The SF determining BS 1 as the interference source may be based on the measurement report, sensing resource configuration information, or other information reported by each base station.
[0051] The recommendation message that indicates sensing may include at least one or more parameters. A first parameter may include a list of <DL Sensing Resource ID, Tx Power>. The DL Sensing Resource ID may identify a DL Sensing Resource. If all the sensing resources indicated by the list of DL Sensing Resource ID use the same Tx power, the information is replaced with a list of DL Sensing Resource ID and Tx power. A second parameter may include a list of <DL Sensing Resource set ID, Tx Power>. DL Sensing Resource set ID may identify a DL Sensing Resource set. If all the sensing resources indicated by the list of DL Sensing Resource set ID use the same Tx power, the information is replaced with a list of DL Sensing Resource ID and Tx power. A third parameter may include a list of DL Sensing Resource ID and Receiving power oversaturation event. The recommendation message may include Maximum allowable receiving power and interfered distance. The interfered distance indicates the distance from the interfered device to the interfering device. If one or more interfered devices are present, the interfered distance indicates the minimum distance from the interfered devices to the interfering device.
[0052] BS 1 may adjust the transmission configuration of the DL sensing resource. For example, BS 1 may adjust the transmission power of beam #5 and beam #6, as shown in FIG. 6. In some embodiments, BS 2 sends a capability message to SF. The capability message may include one or more parameters, such as the max receiving power (i.e., the maximum power the SF can receive) and the maximum allowable interference power (i.e., the maximum allowable interference power the SF can receive) . In some embodiments, after the SF may determines BS 1, SF calculates the Tx power of sensing resources (beam #5 and beam #6) which are interfering BS 2, as shown in FIG. 6. The SF can calculate the Tx power of sensing resources (beam #5 and beam #6) using the equation Tx_power≤Max_receiving_power+passloss, where the passloss is obtained through the location of BS 1 and BS 2.
[0053] Embodiment #2: Power control of bi-static sensing
[0054] In the mobile communication network, in addition to the sensing receiver and sensing transmitter are co-located in the same device (i.e., mono-static sensing) , sensing receiver and sensing transmitter are separated in the different devices (i.e., bi-static sensing) . In FIG. 7, BS 1 sends sensing signals as the sensing transmitter, and BS 2 receivers sensing signals as the sensing receiver. When the sensing objects are close to the middle area between BS 1 and BS 2, BS 1 sends sensing signals, and the transmitting sensing signals of BS 1 is directed towards BS 2, this sensing signals will cause receiving power oversaturation on BS 2.
[0055] When receiving power oversaturation occurs on BS 2, BS 2 sends a measurement report about oversaturation to the sensing function (SF) . The measurement result may include at least one of a Receiving power oversaturation event (i.e., receiving power oversaturation occurs) , a list of <Timestamp, Duration> (i.e., the time when the receiving power oversaturation event occurs) , a duration (i.e., duration of the receiving power oversaturation) , Cell IDs (i.e., identification of the cells where the receiving power oversaturation event occurs) , Antenna Ports (i.e., antenna ports where the receiving power oversaturation event occurs) , and a Potential interference source list (i.e., ID of potential interference source) .
[0056] The SF sends a recommendation message to BS 1 to recommend the new sensing resource configuration. The SF determining BS 1 as the interference source may be based on the measurement report, sensing resource configuration information, or other information reported by each base station. The recommendation message includes one or more parameters. A first parameter may include a list of <DL Sensing Resource ID, Tx Power>. The DL Sensing Resource ID may identify a DL Sensing Resource. If all the sensing resources indicated by the list of DL Sensing Resource ID use the same Tx power, the information is replaced with a list of DL Sensing Resource ID and Tx power. A second parameter may include a list of <DL Sensing Resource set ID, Tx Power>. DL Sensing Resource set ID may identify a DL Sensing Resource set. If all the sensing resources indicated by the list of DL Sensing Resource set ID use the same Tx power, the information is replaced with a list of DL Sensing Resource ID and Tx power. A third parameter may include a list of DL Sensing Resource ID and Receiving power oversaturation event. The recommendation message may include Maximum allowable receiving power and interfered distance. The interfered distance indicates the distance from the interfered device to the interfering device. If one or more interfered devices are present, the interfered distance indicates the minimum distance from the interfered devices to the interfering device.
[0057] BS 1 adjusts the transmission configuration of DL sensing resource. For example, BS 1 adjust the transmission power of beam4, beam #5 and beam #6. Each sensing resource corresponds to a beam as shown in FIG. 8.
[0058] Embodiment #3: Xn DL sensing resource coordination
[0059] FIG. 9 illustrates receiving power oversaturation within a different slot structure. The slot structure of BS 1 is “DDDFU” and the slot structure of BS 2 is “DFUUU” where D represents downlink, U represents uplink, F represents flexible. Mono-static sensing mode may be implemented by BS 1 and BS 2. If BS 1 is transmitting sensing signals in the third “D” slot and BS 2 are receiving communication signal in the first “U” slot, the transmission of BS 1 may cause receiving power oversaturation on BS 2.
[0060] In some embodiments, BSs 102 may provide sensing service and communication service for an unmanned aerial vehicle (UAV) .
