Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to a communication method, an apparatus, and a computer-readable storage medium. Background Art

[0002] Currently, the industry widely discusses introducing artificial intelligence (AI) technology at the level of channel state information (CSI), that is, supporting intelligent CSI compression and recovery. Specifically, an AI model is introduced in a terminal device to compress the estimated CSI, and the compressed CSI is fed back to a network device; an AI model is introduced in the network device to recover the compressed CSI. Through the above method, the feedback overhead of the terminal device can be effectively reduced, and the network device can also obtain high-precision CSI.

[0003] In the prior art, a proxy model can also be set in the terminal device to simulate the CSI model in the network device, so as to evaluate the inference accuracy of the AI model. Summary of the Invention

[0006] The terminal device sends the first information to the network device. Based on the received first information, the network device can determine the matching degree between the proxy model and the CSI reconstruction model, and further can determine whether to manage the proxy model in the terminal device, such as deactivating the proxy model or stopping monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model.

[0008] Optionally, the trigger condition includes: a performance parameter of a communication link is lower than a preset threshold, and / or the proxy model does not match the CSI compression model.

[0009] When the terminal device detects that the triggering condition is met, it sends the first information. Further, when the performance parameter of the communication link is poor and / or the proxy model does not match the CSI compression model, the terminal device sends the first information, which can reduce the uplink overhead of the terminal device.

[0010] Optionally, the terminal device may deactivate the proxy model in response to the mismatch between the proxy model and the CSI reconstruction model, or stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model.

By deactivating the proxy model, or stopping monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model, the power consumption of the terminal device can be reduced.

[0022] Optionally, in response to receiving indication information, deactivate the proxy model, or stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model.

[0042] In the prior art, a proxy model is set in a terminal device to evaluate the inference accuracy of the AI models in the terminal device and the network device.

[0043] In an embodiment of the present invention, the terminal device sends first information to the network device. Based on the first information, the network device can determine whether to deactivate the proxy model in the terminal device, or instruct the terminal device to stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model. Alternatively, the terminal device determines whether to deactivate the proxy model in the terminal device, or instructs the terminal device to stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model. Thereby, the management of the proxy model is realized.

[0044] To make the above objects, features, and beneficial effects of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0045] The terminal device described in the embodiments of this application is a device with wireless communication functions, and can also be referred to as a terminal, mobile station (MS), mobile terminal (MT), access terminal device, in-vehicle terminal device, industrial control terminal device, user equipment (UE), UE unit, UE station, mobile station, remote station, remote terminal device, mobile device, wireless communication device, UE agent, or UE device, etc. The UE can be fixed or mobile. It should be noted that the UE can support at least one wireless communication technology, such as LTE, NR, etc. Exemplarily, the UE can be a mobile phone, tablet (pad), desktop computer, laptop computer, all-in-one computer, in-vehicle terminal, virtual reality (VR) UE, augmented reality (AR) UE, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication functions, computing device, or other processing devices connected to a wireless modem, wearable device, UE in a future mobile communication network, or UE in a future evolved public land mobile network (PLMN), etc. In some embodiments of this application, the UE can also be a device with transceiver functions, such as a chip system. Among them, the chip system can include a chip and can also include other discrete devices.

[0046] In the embodiments of the present application, a network device is a device that provides wireless communication functions for terminal devices, and can also be referred to as a radio access network (RAN) device, or an access network element, an access network device, etc. Among them, the network device can support at least one wireless communication technology, such as LTE, NR, etc. Exemplarily, the network device includes, but is not limited to: the next-generation base station (generation node B, gNB) in 5G, evolved node B (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved node B, or home node B, HNB), baseband unit (BBU), transmitting and receiving point (TRP), transmitting point (TP), mobile switching center, etc. The network device can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in the cloud radio access network (CRAN) scenario, or the network device can be a relay station, an access point, a vehicle-mounted device, a terminal device, a wearable device, and a network device in future mobile communications or a network device in a future evolved PLMN, etc. In some embodiments, the network device can also be a device with the function of providing wireless communication for terminal devices, such as a chip system. Exemplarily, the chip system can include a chip and can also include other discrete devices.

[0047] In some embodiments, the network device can also communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks.

[0048] In the embodiments of the present application, CSI can be used to describe information related to channel quality. For example, CSI describes the propagation process of a wireless signal between a transmitter and a receiver, including the effects of distance, scattering, fading, etc. on the signal. For downlink transmission, CSI can be used for a terminal device to feedback the downlink channel quality to the network device, so that the network device can perform processing such as beam management and mobility management based on the CSI. The CSI sent by the terminal device to the network device can be carried in a CSI report.

[0049] For example, CSI may also include at least one of the following: channel state information-reference signal resource indicator (CRI), rank indicator (RI), channel quality indicator (CQI), precoding matrix indicator (PMI), layer indicator (LI), layer 1-reference signal receiving power (L1-RSRP), layer 1-signal to interference plus noise ratio (L1-SINR), capability index, time-domain channel properties (TDCP), channel information, etc.

[0050] In an embodiment of the present application, the terminal device performs channel measurement through a downlink reference signal to obtain channel information. Measurement can also be described as evaluation, detection, estimation, etc. Among them, the downlink reference signal may include, but is not limited to, channel state information-reference signal (CSI-RS), synchronization signal block (SSB), or physical broadcast channel demodulation reference signal (PBCH DMRS), etc. For example, the terminal device may perform downlink channel measurement according to CSI-RS to obtain channel matrix information, so as to obtain CSI according to the channel matrix information.

[0051] In the embodiments of the present application, channel information can be used to characterize channel features or characteristics. For example, the channel information can be channel matrix information, and / or, it can be CSI, and / or, it can be a channel feature vector. Or, the channel information can also be a CSI report. Or, the channel information can also be the time-domain information of the channel, the frequency-domain information of the channel, the time-frequency-domain information of the channel, or the channel information in the delay-doppler domain, etc., and no specific limitation is made thereto. The channel matrix information and CSI will be elaborated below.

[0052] Among them, the channel matrix information can be used to describe information related to the channel matrix. For example, the channel matrix information can include one or more of the following: channel matrix H, equivalent channel matrix, precoding matrix W (the precoding matrix W can be derived from the channel matrix H), the right singular vector V of the channel matrix H, square matrix H T The eigenvector v of H i 、the vector associated with the channel matrix H (such as the vector of the channel matrix H under a certain transformation, etc.), the channel matrix H T The vector associated with H (such as the vector of H T under a certain transformation, etc.).

[0053] The embodiments of the present invention provide a communication method, refer to Figure 1 , and the following will be described in detail through specific steps.

[0054] In specific implementation, the communication method provided in the following steps 101 to 102 can be executed by a chip with data processing capabilities in the terminal device (such as a baseband chip, etc.), or by a chip module with data processing capabilities in the terminal device, or by the terminal device. The following takes the terminal device executing the communication method as an example for illustration.

[0055] Step 101, send the first information.

[0056] In specific implementation, the network device can configure channel state information reference signal (CSI-RS) for the terminal device and send the configured CSI-RS to the terminal device. The terminal device performs channel estimation operations based on the received CSI-RS to obtain CSI.

[0057] Refer to Figure 2 , and a schematic diagram of a scenario applying an AI model in the embodiments of the present invention is given.

[0058] In a terminal device, a CSI compression model 201 may be deployed to compress the estimated CSI through the CSI compression model 201. The terminal device may feedback the compressed CSI to a network device. In the network device, a CSI reconstruction model 202 corresponding to the CSI compression model 201 may be deployed. The network device receives the compressed CSI and reconstructs the compressed CSI through the CSI reconstruction model 202, that is, restores the compressed CSI.

[0059] A proxy model may also be deployed in the terminal device. The proxy model may be used to simulate the CSI reconstruction model deployed in the network device, and then evaluate the inference accuracy of the CSI compression model and / or the CSI reconstruction model. The proxy model may be similar to the CSI reconstruction model and can restore the compressed CSI.

[0060] In a specific implementation, if the accuracy requirement for the output result of the proxy model is relatively high, the terminal device needs to have strong storage capabilities and computing capabilities, and the structure of the proxy model is relatively complex. In actual applications, the terminal device has a relatively low accuracy requirement for the proxy model, so a proxy model with a relatively low complexity can be selected.

[0061] That is to say, compared with the CSI reconstruction model, the structure of the proxy model can be simpler, and the accuracy of the output result of the proxy model can be lower than that of the CSI reconstruction model.

[0062] In some embodiments, the proxy model may be a simplified CSI reconstruction model.

[0063] In other embodiments, the proxy model may be a model corresponding to the CSI compression model. This model has a CSI reconstruction function and can restore the compressed CSI.

[0064] In an embodiment of the present invention, the terminal device may send first information to the network device. The first information may include at least one of the following: the matching degree between the proxy model and the CSI compression model, the accuracy of the output result of the proxy model, the output result of the proxy model, the first request information, and the second request information.

[0065] In a specific implementation, the matching degree between the proxy model and the CSI compression model may be characterized by the similarity between the output result of the proxy model and the output result of the CSI compression model. The higher the similarity between the output result of the proxy model and the output result of the CSI compression model, the higher the matching degree between the proxy model and the CSI compression model.

[0066] In some embodiments, the similarity between the output result of the proxy model and the output result of the CSI compression model may be obtained by calculating the Euclidean distance between the output result of the proxy model and the output result of the CSI compression model.

[0067] In some other embodiments, the similarity between the output result of the proxy model and the output result of the CSI compression model is calculated by calculating the Manhattan distance, Pearson correlation coefficient, cosine similarity, etc. between the two.

[0068] In a specific implementation, since the proxy model is deployed in the terminal device, the terminal device can obtain the output result of the proxy model. The output result of the proxy model is the result of the proxy model restoring the compressed CSI. The terminal device can compare the output result of the proxy model with the CSI before compression, and thus can determine the accuracy of the output result of the proxy model.

[0069] In some embodiments, the terminal device can send the accuracy of the output result of the proxy model to the network device. In some other embodiments, the terminal device can only send the output result of the proxy model to the network device. In still some other embodiments, the terminal device can send both the output result of the proxy model and the accuracy of the output result to the network device.

[0070] In a specific implementation, the terminal device can send a first request message to the network device, and the first request message is used to request the output result of the CSI reconstruction model. After receiving the first request message, the network device can send the output result of the CSI reconstruction model to the terminal device. The terminal device can obtain the output result of the CSI reconstruction model. Thus, the terminal device can determine the accuracy of the output result of the proxy model based on the output result of the CSI reconstruction model and the output result obtained by the proxy model.

[0071] In the embodiments of the present invention, before sending the first message, the terminal device can further determine whether a preset trigger condition is satisfied. If the preset trigger condition is satisfied, step 101 can be executed; otherwise, if the preset trigger condition is not satisfied, step 101 does not need to be executed.

[0072] That is to say, the terminal device's determination of whether the preset trigger condition is satisfied is an optional item for executing step 101. When the terminal device detects that the trigger condition is satisfied and sends the first message, the uplink overhead of the terminal device can be reduced.

[0073] In some embodiments, when it is determined that the trigger condition is satisfied, the terminal device sends the first message. In some other embodiments, when the terminal device sends the first message to the network device, it does not need to detect whether the trigger condition is satisfied.

[0074] In a specific implementation, the trigger condition may include: the performance parameter of the communication link is lower than a preset threshold, and / or the proxy model does not match the CSI compression model, and / or the accuracy of the output result of the proxy model is lower than a preset threshold.

[0075] Specifically, the performance parameter of the communication link being lower than the preset threshold may mean that: the bit error rate of the communication link is greater than the preset bit error rate threshold, or the block error rate of the communication link is greater than the preset block error rate threshold. Among them, the above-mentioned preset threshold may be defined by the protocol, configured by the network device, or from the terminal device capability information.

[0076] It can be understood that the performance parameters of the communication link may also include other parameters, such as data transmission rate, data transmission bandwidth, channel capacity, etc.

[0077] The mismatch between the proxy model and the CSI compression model may mean that: the similarity between the output result of the proxy model and the CSI before compression is lower than the similarity threshold.

[0078] In some embodiments, the similarity threshold may be pre-set. When the similarity between the output result of the proxy model and the CSI before compression is lower than the similarity threshold, it can be determined that the proxy model and the CSI compression model do not match; conversely, when the similarity between the output result of the proxy model and the CSI before compression is greater than the similarity threshold, it can be determined that the proxy model and the CSI compression model match.

[0079] The similarity threshold can be configured by the network device and sent by the network device to the terminal device through high-layer signaling (such as RRC signaling, MAC CE, etc.). The similarity threshold can also be pre-defined. For example, the similarity threshold is pre-defined in the communication protocol. It can be understood that the above-mentioned similarity threshold can also be from the terminal device capability information.

[0080] In specific implementation, the triggering condition may also include: detecting that the performance parameter of the communication link gradually deteriorates. The performance parameter of the communication link gradually deteriorating may mean that the matching degree between the proxy model and the CSI compression model gradually deteriorates.

[0081] An optional solution is provided. In the embodiments of the present invention, the communication method may further include the following steps:

[0082] Step 102, deactivate the proxy model, or stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model.

[0083] In the embodiments of the present invention, the terminal device may determine whether the proxy model and the CSI reconstruction model match.

[0084] In some embodiments, the terminal device may send first request information to the network device, requesting the network device to send the output result of the CSI reconstruction model. The network device sends the output result of the CSI reconstruction model to the terminal device. The terminal device compares the output result of the proxy model with the output result of the CSI reconstruction model, and then can obtain the matching degree between the proxy model and the CSI reconstruction model, and further determine whether the proxy model matches the CSI reconstruction model.

[0085] In some other embodiments, the terminal device may determine whether the proxy model matches the CSI reconstruction model based on the accuracy of the output result of the proxy model. If the accuracy of the output result of the proxy model is lower than a preset accuracy threshold, it may be determined that the proxy model does not match the CSI reconstruction model; otherwise, it may be determined that the proxy model matches the CSI reconstruction model.

[0086] In the embodiments of the present invention, it may also be determined by the network device whether the proxy model matches the CSI reconstruction model.

[0087] In some embodiments, the network device may receive the output result of the proxy model sent by the terminal device and compare the output result of the proxy model with the output result of the CSI reconstruction model. Thus, the network device can know whether the proxy model matches the CSI reconstruction model.

[0088] In some embodiments, the network device may receive the output result of the proxy model sent by the terminal device and compare the output result of the proxy model with the output result of the CSI reconstruction model. The network device may send the comparison result to the terminal device. Thus, the terminal device can know whether the proxy model matches the CSI reconstruction model.

[0089] In the embodiments of the present invention, if the terminal device determines that the proxy model does not match the CSI reconstruction model, the terminal device may deactivate the proxy model.

[0090] In some embodiments, for the terminal device to deactivate the proxy model may mean that the terminal device stops using the proxy model.

[0091] In a specific application, the terminal device may monitor the CSI compression model and / or the CSI reconstruction model to evaluate the inference accuracy of the CSI compression model and / or the CSI reconstruction model. Specifically, the terminal device may monitor the CSI compression model and / or the CSI reconstruction model using different monitoring types.

[0092] Specifically, the terminal device can monitor the CSI compression model and / or the CSI reconstruction model based on the proxy model; the terminal device can also monitor the CSI compression model and / or the CSI reconstruction model based on the data characteristics of the input data / output data; the terminal device can further monitor the CSI compression model and / or the CSI reconstruction model based on the confidence label mechanism.

[0093] It can be understood that with the development of technology and the further evolution of communication protocols, other monitoring types capable of monitoring the CSI compression model and / or the CSI reconstruction model may also appear, not limited to the several monitoring types provided in the above content. Due to space limitations, in the embodiments of the present invention, the monitoring types for monitoring the CSI compression model and / or the CSI reconstruction model are not exhaustively listed.

[0094] In the embodiments of the present invention, if the terminal device detects that the proxy model does not match the CSI reconstruction model, the terminal device can stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model and switch the monitoring type for monitoring the CSI compression model and / or the CSI reconstruction model.

[0095] In some embodiments, the terminal device can monitor the CSI compression model and / or the CSI reconstruction model based on the confidence label mechanism. In other embodiments, the terminal device can monitor the CSI compression model and / or the CSI reconstruction model based on the data characteristics of the input data / output data.

[0096] In the embodiments of the present invention, the terminal device can also send a second request message to the network device. The second request message is used to request the network device to configure the monitoring type for monitoring the CSI compression model and / or the CSI reconstruction model. In the second request message, configuration parameters related to the requested monitoring type can also be included. After receiving the second request message, the network device sends the monitoring type and / or the configuration parameters related to the monitoring type to the terminal device through the configuration information. The terminal device obtains the configuration information and monitors the CSI compression model and / or the CSI reconstruction model using the requested monitoring type based on the configuration parameters corresponding to the monitoring type.

[0097] For example, the terminal device sends a second request message to the network device. The second request message is used to request the network device to configure the monitoring type and the configuration parameters. The network device configures the monitoring type for the terminal device through the configuration information as: monitoring the CSI compression model and / or the CSI reconstruction model based on the data characteristics of the input data / output data. The terminal device receives the configuration information and monitors the CSI compression model and / or the CSI reconstruction model based on the data characteristics of the input data / output data.

[0098] In an embodiment of the present invention, the network device may also determine whether to deactivate the proxy model based on the first information, or whether to stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model. If the network device determines to deactivate the proxy model and / or determines to stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model, the network device may generate indication information and send the indication information to the terminal device. The network device may send the indication information to the terminal device by means of RRC signaling, downlink control messages, etc.

[0099] The terminal device receives the indication information. Based on the indication information, it can determine to deactivate the proxy model; or stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model.

[0100] In an embodiment of the present invention, monitoring the CSI compression model and / or the CSI reconstruction model may include: monitoring the CSI compression model; or monitoring the CSI reconstruction model; or monitoring a model pair composed of the CSI compression model and the CSI reconstruction model.

[0101] In summary, with the above solution, the proxy model deployed in the terminal device can be managed.

[0102] It should be noted that the above step 102 is an optional step. Or, the above step 102 may be independent of step 101. That is to say, there may be no necessary logical association between step 101 and step 102.

[0103] In some embodiments, the terminal device executes step 102 after completing step 101. In other embodiments, the terminal device only needs to execute step 101 and does not need to execute the subsequent step 102.

[0104] In still other embodiments, the terminal device can execute step 102 without sending the first information.

[0105] For example, the network device sends indication information to the terminal device. The terminal device receives the indication information and executes the above step 102. In this scenario, the execution of step 102 may not depend on step 101.

[0106] For another example, if the terminal device detects that the current remaining computing power is insufficient or the current remaining operating space is insufficient, the terminal device may execute step 102. In this scenario, the execution of step 102 may not depend on step 101.

[0107] Refer to Figure 3 , another communication method in the embodiment of the present invention is given, and the following is described in detail through specific steps.

[0108] In a specific implementation, the communication method provided in the following steps 301 to 302 may be executed by a chip with data processing capabilities in the terminal device (such as a baseband chip, etc.), or by a chip module with data processing capabilities in the terminal device, or by the terminal device. The following uses the terminal device executing the communication method as an example for illustration.

[0109] Step 301: Deactivate the proxy model, or stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model.

[0110] In a specific implementation, when the terminal device detects that the proxy model does not match the CSI reconstruction model, it may deactivate the proxy model, or stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model.

[0111] In a specific implementation, when the terminal device receives the indication information, it may also deactivate the proxy model, or stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model. The indication information may be sent by the network device.

[0112] In a specific implementation, when the terminal device detects that the current remaining computing power is insufficient or the current remaining operating space is insufficient, it may deactivate the proxy model, or stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model.

[0113] Step 302: Obtain configuration information.

[0114] In a specific implementation, the terminal device may also send a second request message to the network device. The second request message is used to request the network device to configure the monitoring type for monitoring the CSI compression model and / or the CSI reconstruction model. In the second request message, configuration parameters related to the requested monitoring type may also be included. After receiving the second request message, the network device sends the monitoring type and / or the configuration parameters related to the monitoring type to the terminal device through the configuration information. The terminal device obtains the configuration information and monitors the CSI compression model and / or the CSI reconstruction model using the requested monitoring type based on the configuration parameters corresponding to the monitoring type.

[0115] Alternatively, even if the network device does not receive the second request message, it may also send the configuration information to the terminal device. For example, the network device may pre - send the configuration information to the terminal device, and the network device may indicate the monitoring type to the terminal device in the manner of downlink control information.

[0116] In an embodiment of the present invention, step 302 is an optional step. That is to say, there is no inevitable logical relationship between step 301 and step 302. If the terminal device needs to obtain configuration information, the terminal device executes step 302 after completing the execution of step 301. If the terminal device does not need to obtain configuration information, the terminal device does not need to execute step 302.

[0117] Referring to Figure 4 , another communication method in the embodiment of the present invention is given, and the following is described through specific steps.

[0118] In a specific implementation, the communication method provided below can be executed by a chip with data processing capabilities in the network device, or by a chip module with data processing capabilities in the network device, or by the network device. The following takes the network device executing the communication method as an example for description.

[0119] Step 401, send indication information.

[0120] In an embodiment of the present invention, the network device may send indication information to the terminal device, and the indication information indicates to deactivate the proxy model, or indicates to stop monitoring the CSI compression model / CSI reconstruction model based on the proxy model.

[0121] The terminal device receives the indication information. Based on the indication information, it can determine to deactivate the proxy model; or stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model.

[0122] That is to say, the network device can directly send indication information to the terminal device to instruct the terminal device to perform corresponding management on the proxy model.

[0123] In an embodiment of the present invention, before sending the indication information, the network device may further execute the following steps:

[0124] Step 400, obtain first information.

[0125] In a specific implementation, the terminal device may send first information to the network device. The first information may include at least one of the following: the matching degree between the proxy model and the channel state information CSI compression model, the output result of the proxy model, the first request information, the second request information; the first request information is used to request the output result of the CSI reconstruction model corresponding to the CSI compression model, and the second request information is used to request the monitoring type for monitoring the CSI compression model and / or the CSI reconstruction model.

[0126] The network device may determine whether to deactivate the proxy model or whether to stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model according to the first information. If the network device determines to deactivate the proxy model and / or determines to stop monitoring the CSI compression model and / or the CSI reconstruction model based on the proxy model, the network device may generate indication information and send the indication information to the terminal device. The network device may send the indication information to the terminal device by means of RRC signaling, downlink control messages, etc.

[0127] In a specific implementation, if the terminal device sends a second request message to the network device, the network device may further send configuration information to the terminal device, and the configuration information may include the monitoring type corresponding to the second request message.

[0128] It should be noted that the above step 400 is an optional item, and step 401 may not depend on step 400. That is to say, the network device may send the indication information without receiving the first information. In other words, there is no inevitable logical relationship between the network device sending the indication information and whether it receives the first information.

[0129] For example, the network device may determine to send the indication information based on information such as scheduling requirements and perceived radio environment parameters.
