DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0021] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0022] Figure 1 The flowchart of the embodiment of the method of the present application is as follows. The embodiment of the present application proposes a synaesthesia power control method, which is applied to the synaesthesia station sensing signal transmission, and includes the following steps 110-140: Step 110: Obtain a transmission path loss between the first base station and the second base station.

[0023] It should be noted that the first base station is a telepathic station, that is, it can send and receive communication signals and also can send and receive perception signals. The second base station is a base station adjacent to the first base station, and can be a telepathic station or a communication station, and the communication station is a base station that only sends and receives communication signals.

[0024] Preferably, the obtaining of the transmission path loss between the first base station and the second base station includes: the first base station sends a measurement signal to the second base station, and the second base station determines the transmission path loss based on the received power of the measurement signal; or, the second base station sends a measurement signal to the first base station, and the first base station determines the transmission path loss based on the received power of the measurement signal.

[0025] Specifically, according to the first method, one method of obtaining the transmission path loss PL is that the first base station sends a path loss measurement signal to the second base station, and the second base station measures the signal receiving power P r1 , and the received power P r1 Or the calculated transmission path loss is fed back to the first base station. The first base station obtains the feedback receiving power P r1 After that, according to the path loss measurement signal transmission power P t1 Calculate the transmission path loss PL=P t1 -P r1 Optionally, the first base station obtains the feedback information (the second base station measures the received power P r1 Or calculate the transmission path loss) directly through the transmission interface between the second base station, or the second base station feeds it back to the core network element, and then the core network element transmits it to the first base station.

[0026] Specifically, according to the second method, another method for obtaining the transmission path loss PL is that the second base station sends a path loss measurement signal to the first base station, and the first base station measures the signal receiving power P r2 , and according to the received power P r2 and the obtained transmission power P of the path loss measurement signal sent by the second base station t2 Calculate the transmission path loss PL=P t2 -P r2 Optionally, the first base station obtains the transmission power P of the path loss measurement signal sent by the second base station. t2 The information is directly obtained through the transmission interface between the second base station, or the second base station feeds it back to the core network element, which then transmits it to the first base station.

[0027] In an embodiment of the present application, preferably, the transmission path loss is also changed according to the transmission beam of the first base station and / or the receiving beam of the second base station. Specifically, different beams correspond to different transmission path losses, and the first base station obtains the transmission path losses under different transmission beams and / or different receiving beams of the second base station.

[0028] Step 120: Determine a target power for the second base station to receive the perception signal.

[0029] The perception power is the power of the perception signal sent by the telepathic base station (first base station), which can coexist simultaneously with the uplink signal of the second base station on the same frequency. The interference coexistence between the uplink signal and the perception signal is managed by configuring the perception signal target power. The lower the perception signal target power is, the smaller the interference to the second base station in receiving the uplink signal will be.

[0030] In one embodiment, determining the target power for the second base station to receive the perception signal includes: receiving configuration information, where the configuration information includes the target power for the second base station to receive the perception signal.

[0031] In one embodiment, the method further comprises the following steps: determining a perception signal power configuration parameter, wherein the perception signal power configuration parameter comprises at least one of the following: a maximum transmit power of the perception signal, a target power for the second base station to receive the perception signal, and a path loss compensation factor.

[0032] In an embodiment of the present application, preferably, the following steps are also included: the first base station receives a perception signal power configuration parameter from a core network element or a second base station.

[0033] In the embodiment of the present application, preferably, the perception signal power configuration parameter is also changed according to the perception signal transmission priority. Optionally, the perception signal transmission power configuration is related to the perception signal transmission priority, that is, different transmission priorities may correspond to different maximum perception signal transmission powers P max , and / or, target power P of different sensing signals to the second base station target For example, a higher transmission priority perception signal can correspond to a higher target power P target .

[0034] It should be noted that, in order to avoid interference with the uplink communication signal, the perception signal power configuration parameter can be specifically used for an application scenario where the perception signal and the uplink communication signal of the second base station interfere with each other. In response to interference between the perception signal and the uplink communication signal of the second base station, the first base station obtains a transmission power configuration for the coexistence of interference between the perception signal and the uplink communication signal of the second base station, or, in response to interference between the perception signal and the uplink communication signal of the second base station, the first base station activates a transmission power configuration for the coexistence of interference between the perception signal and the uplink communication signal of the second base station.

[0035] When the perception signal transmission power configuration is updated or needs to be activated, the first base station determines the perception signal transmission power based on the updated power configuration in the next perception signal transmission time slot after receiving the updated transmission power configuration, or determines the subsequent perception signal transmission power configuration based on the updated or activated power configuration after the configuration effective time T. The effective time is agreed according to the protocol, or the first base station obtains it from the core network element or the second base station.

[0036] Step 130: Determine the transmission power of the first base station perception signal according to the transmission path loss and the target power.

[0037] The perception signal transmission power configuration includes: the maximum transmission power P of the perception signal max , the target power P of the sensing signal to the second base station target Optionally, the sensing signal transmission power configuration also includes a path loss compensation factor a Furthermore, the cognitive signal transmission power configuration includes the cognitive signal maximum transmission power P on the i-th cognitive signal transmission opportunity. max (i) Target power P of the sensing signal to the second base station target (i).

[0038] The perception signal transmission power is configured by the first base station according to a protocol agreement, or is obtained from a core network element or a second base station. In one embodiment, the transmission power of the i-th perception signal transmission opportunity is determined as: P t (i)=min{P max (i),P target (i)+ a ×PL+f(M(i))+g(MCS(i))+y(b(i))+h(i)} (1) Wherein M(i) is the number of resources occupied by the perception signal, f(M(i)) represents a power adjustment function related to the number of resources occupied by the perception signal, MCS(i) is the modulation and coding level adopted by the perception signal, g(MCS(i)) represents a power adjustment function related to the modulation and coding level adopted by the perception signal, b(i) is the signal format adopted by the perception signal, y(b(i)) represents a power adjustment function related to the perception signal format, h(i) is the power adjustment amount of the perception signal under closed-loop power control, and PL is the transmission path loss between the first base station and the second base station obtained in step 110.

[0039] It should be noted that the goal of power regulation is to manage the final transmission power of the sensing signal to manage the reception interference to the uplink signal.

[0040] Optionally, when the sent power of the perception signal is not related to the number of resources occupied by the perception signal, the corresponding f(M(i)) value is 0. When the sent power of the perception signal is not related to the MCS level adopted by the perception signal, the corresponding g(MCS(i)) value is 0. When the sent power of the perception signal is not related to the format of the perception signal, the corresponding y(b(i)) value is 0. When the sent power of the perception signal does not adopt closed-loop power control, the value of h(i) is 0.

[0041] In one embodiment, the following steps are also included: obtaining a closed-loop power control adjustment amount, and making a cumulative adjustment or an absolute value adjustment to the transmission power of the first base station's perception signal. In the optional closed-loop power control, the first base station obtains a closed-loop power control adjustment amount δ from the core network element or the second base station, and the first base station makes a cumulative adjustment or an absolute value adjustment to the corresponding perception signal transmission power according to h(i). The cumulative adjustment is h(i)=h(i-1)+δ, and the absolute value adjustment is h(i)=δ.

[0042] In the embodiment of the present application, preferably, the transmit power is also changed according to the transmit beam of the first base station and / or the receive beam of the second base station. The optional transmit power is related to the transmit beam of the first base station, that is, the transmit power related parameters (such as P target (i), M(i)), MCS(i), b(i), h(i), PL) are related to the first base station's transmit beam. Further, optionally, the transmit power is related to the first base station's transmit beam and the second base station's receive beam, that is, the above transmit power related parameters (such as P target (i), M(i)), MCS(i), b(i), h(i), PL) are related to the first base station's transmit beam and the second receive beam. Further optionally, when the transmit power is related to the first base station's transmit beam, in order to save the perception signal power control measurement and signaling overhead, when the first base station switches the beam to send the perception signal that coexists with the uplink interference of the second base station, the transmit power of the switching beam j in the i-th perception signal transmission opportunity is: P t (i,j)=min{P max (i,j),P t (k)+θ(j,k)}(2) Where P max (i, j) is the maximum transmission power of beam j sent by the first base station, P t (k) is the transmission power of the sensing signal in the transmission beam k before switching, and θ(j,k) is the power deviation between the transmission beam j and the transmission beam k.

[0043] The first base station obtains the power deviation θ(j, k) between different beams in the following manner: according to the protocol agreement, or the first base station obtains it from the core network element or the second base station.

[0044] It should also be noted that, optionally, when a first base station corresponds to multiple second base stations, that is, when the uplink communication signals of the first base station and the multiple second base stations coexist with interference, the perception signal sending power determined by the first base station is the minimum value between the maximum sending power of the perception signal of the first base station and the perception signal sending power determined under the relevant second base stations.

[0045] Step 140: The first base station sends a perception signal based on the determined perception signal sending power.

[0046] The first base station configures the sensing signal according to the sensing signal transmission power corresponding to the transmission beam determined in steps 110 to 130, if the sensing signal configuration coexists with uplink interference of the neighboring second base station. It should be noted that the above steps are used for network entities of a wireless communication system, including network-side devices or other intermediate devices; the above steps can also be used for service devices that provide information processing for the network entity devices; the above steps can also be used for any device, system, subsystem, circuit, chip or software entity that provides information reception, transmission, identification, and processing for network-side devices or other intermediate devices.

As shown in the figure below, the transmission path loss corresponds to the transmission path loss of the second base station's transmission beam 1, transmission beam 2, ... transmission beam K. According to channel reciprocity, the transmission path loss is further used to correspond to the transmission path loss of the first base station's transmission beam 1, transmission beam 2, ... transmission beam N. The specific corresponding method is based on the protocol agreement, or the first base station obtains it from the core network element or the second base station.

As shown in the figure below, the transmission path loss corresponds to the receiving power or transmission path loss under the second base station and the first base station beam pairing (transmitting beam k, receiving beam l), where k=1, 2,…, K; l=1, 2,…, L.
