Description

Communication method and device

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for communication.

Background

When using a terminal device, such as a mobile phone, the transmitting antenna is located relatively close to the brain or other parts of the human body, and in order to avoid emitting too much electromagnetic radiation, there are generally some safety standards to ensure that there is not too much electromagnetic radiation, thereby ensuring the safety of people using the mobile phone. For example, whether the influence of radiation from a terminal device (such as a mobile phone) on a human body meets a standard or not may be measured by maximum permissible radiation exposure (MPE) or Specific Absorption Rate (SAR).

In some communication systems, such as a fifth generation (5G) system or a New Radio (NR), in order to satisfy wide area coverage, both the network device and the terminal device are deployed with multiple antenna panels, and beams used for communication between the network device and the terminal device are transmitted or received through the antenna panels (antenna panels). Especially for terminal equipment, antenna panel deployment is more important to the performance impact in order to meet coverage, and with limited space and cost savings.

Therefore, in a scenario where the terminal device is deployed by using a multi-antenna panel, how to ensure that the radiation intensity of the terminal device meets the safety standard and the transmission performance can be ensured.

Disclosure of Invention

The application provides a communication method and device, which can not only prevent the radiation intensity from exceeding the regulation limit, but also realize the uplink transmission enhancement based on the radiation intensity constraint.

In a first aspect, a method of communication is provided. The method may be performed by a sending end device. For example, the sending end device may be a terminal device, that is, the method may be executed by the terminal device, or may be executed by a chip or a chip system or a circuit configured in the terminal device. In addition, when the sending end device is a terminal device, the receiving end device may be a network device. For another example, the sending end device may also be a network device, that is, the method may also be executed by the network device, or may also be executed by a chip or a chip system or a circuit configured in the network device. In addition, when the sending end device is a network device, the receiving end device may be a terminal device. This is not a limitation of the present application.

The method can comprise the following steps: reporting the information of the radiation intensity; communicating using a target beam and/or a target antenna panel; wherein the target beam is a default beam, and/or the target antenna panel is a default antenna panel; alternatively, the target beam is an indicated beam, and/or the target antenna panel is an indicated antenna panel, and the indicated beam and/or the indicated antenna panel is one or more of candidate beams and/or candidate antenna panels.

In one possible approach, the target beam is a default beam, and/or the target antenna panel is a default antenna panel. Based on the scheme, the method can comprise the following steps: reporting the information of the radiation intensity; communication is performed using a default beam and/or a default antenna panel.

Based on the above technical solution, signaling overhead, transmission delay, reliability, and complexity compromise are comprehensively considered, and the terminal device and the network device may use a default beam and/or a default antenna panel to communicate (e.g., transmit data or signals). Taking the terminal device as an example, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the network device does not need to indicate the terminal device the specific information of the beam and/or the antenna panel used for transmitting data, and the terminal device can use the default beam and/or the default antenna panel for communication (such as transmitting data or signals). Therefore, the radiation intensity can be prevented from exceeding the regulation limit, the signaling overhead can be reduced, and the transmission time delay can be reduced.

Yet another possible approach is that the target beam is the indicated beam and/or the target antenna panel is the indicated antenna panel. Based on the scheme, the method can comprise the following steps: reporting the information of the radiation intensity; communicating using the indicated beam and/or the indicated antenna panel; wherein the indicated beam is one or more of the candidate beams and the indicated antenna panel is one or more of the candidate antenna panels.

Alternatively, the candidate beam or the candidate antenna panel may be an activated beam or antenna panel.

Based on the above technical solution, signaling overhead, transmission delay, reliability, and complexity compromise are comprehensively considered, and the terminal device and the network device may use the indicated beam and/or the indicated antenna panel to communicate (e.g., transmit data or signals). Taking the terminal device as an example, when the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limit, the network device may designate one or more of the candidate beams and/or candidate antenna panels for communication, or the network device may instruct the terminal device to select one or more of the candidate beams and/or candidate antenna panels for communication. Thereby, it is possible to avoid that the radiation intensity exceeds the legislative limits. In addition, a suitable beam and/or antenna panel can be selected according to the actual communication situation, so that not only can the beams of the terminal device and the network device be aligned, but also the communication performance can be improved.

Yet another possible approach is for the target antenna panel to be the default antenna panel, and for the target beam to be the indicated beam; alternatively, the target antenna panel is the indicated antenna panel and the target beam is the default beam.

With reference to the first aspect, in certain implementations of the first aspect, the using a target beam and/or a target antenna panel for communication includes: communicating using the target beam and/or the target antenna panel upon receiving a response message.

An example of the response message is an Acknowledgement (ACK) message. Taking the information of the radiation intensity reported by the terminal device as an example, the network device may perform ACK confirmation on the information of the radiation intensity reported by the terminal device, for example, confirm that the information of the radiation intensity is successfully received through a New Data Indicator (NDI) flipping method in Downlink Control Information (DCI). In this example, the terminal device may communicate with the network device using a default beam and/or a default panel upon receiving the message.

For yet another example, the response message may be carried in the control information, indicated by 1 bit (bit) or multiple bits in the control information. Taking the terminal device as an example, the network device may instruct the terminal device to use a default beam and/or a default panel to communicate with the network device through 1 bit or more bits in the control information, for example. For another example, the network device may also display the beam and/or the panel used by the terminal device through 1 bit or multiple bits in the control information.

Based on the above technical solution, after receiving the response message, for example, after responding to the reported radiation intensity, the target beam and/or the target antenna panel is used for communication. Therefore, the beams of the transceiving end device (such as the beams of the terminal device and the network device) can be aligned, and the communication performance is improved.

With reference to the first aspect, in certain implementations of the first aspect, the reporting the information on the radiation intensity includes: reporting the information of the radiation intensity under the condition that the adopted power back-off value is larger than a first threshold; or reporting the information of the radiation intensity under the condition that the quality of the wave beam after the power return is not optimal and/or the quality of the antenna panel after the power return is not optimal; or reporting the information of the radiation intensity under the condition that the quality of the wave beam after the power return is smaller than a second threshold and/or the quality of the antenna panel after the power return is smaller than a third threshold; or reporting the information of the radiation intensity under the condition that the channel capacity is smaller than a fourth threshold; or reporting the information of the radiation intensity periodically.

Based on the technical scheme, the information of the radiation intensity can be reported under the condition of meeting a certain condition, so that the signaling overhead caused by unnecessary reporting can be avoided.

With reference to the first aspect, in certain implementations of the first aspect, the activated beams include N beams, and/or the activated antenna panels include M antenna panels, N, M each being an integer greater than 1 or equal to 1; the default beam is a beam with the best beam quality in the N beams, and/or the default antenna panel is an antenna panel with the best antenna panel quality in the M antenna panels; or, the default beam includes a beam of the N beams whose beam quality is greater than a fifth threshold, and/or the default antenna panel includes an antenna panel of the M antenna panels whose antenna panel quality is greater than a sixth threshold; or the default beam comprises T1 different beams of the N beams, and/or the default antenna panel comprises T2 different antenna panels of the M antenna panels, T1, T2 are both integers greater than 1, and T1 is less than or equal to N, T2 and less than or equal to M; or the default beam is a power-backed beam, and/or the default antenna panel is a power-backed antenna panel; or the default beam is a beam with power not returned, and/or the default antenna panel is an antenna panel with power not returned; or the default beam is a beam requested to be used, and/or the default antenna panel is an antenna panel requested to be used; or, the default beam includes a beam of the N beams except for a beam used for current communication, and/or the default antenna panel includes an antenna panel of the M antenna panels except for an antenna panel used for current communication.

Optionally, the default beam is a power-backed beam and/or the default antenna panel is a power-backed antenna panel when the following conditions are met: the power back-off value is smaller than a preset threshold; or the quality of the wave beam after the power return is larger than a second threshold, and/or the quality of the antenna panel after the power return is larger than a third threshold; or, the power-backed beam is a beam with the best beam quality among the N beams, and/or the power-backed antenna panel is an antenna panel with the best beam quality among the M antenna panels.

Based on the above technical solution, there are many possible forms of the default beam and/or the default antenna panel, and in particular, detailed in the following embodiments.

With reference to the first aspect, in certain implementations of the first aspect, the using a target beam and/or a target antenna panel for communication includes: repeatedly transmitting data using the target beam and/or target antenna panel.

Optionally, the data is transmitted repeatedly or, so to speak, the data is transmitted repeatedly. Taking the antenna panel as an example, the repeated transmission of data or the transmission of repeated data means that the same data is transmitted by using different antenna panels. For example, a different Redundancy Version (RV) and/or a different modulation and coding scheme may be used each time data is transmitted.

Based on the technical scheme, the target beam and/or the target antenna panel can be used for repeatedly transmitting data, so that the reliability of data transmission can be improved as much as possible.

With reference to the first aspect, in certain implementations of the first aspect, repeatedly transmitting data using the target beam and/or target antenna panel includes: the data is repeatedly transmitted using a plurality of different beams and/or a plurality of different antenna panels, or the data is repeatedly transmitted using the same beam and/or the same antenna panel.

With reference to the first aspect, in certain implementations of the first aspect, the information on radiation intensity includes one or more of: information of the target beam and/or target antenna panel; the candidate beam and/or the candidate antenna panel; power density; the maximum allowable radiation MPE problem occurs; MPE percentage; a power backoff indicator; a power backoff value; a power headroom or an energy headroom; the uplink transmission duty ratio identification needs to be reduced; the uplink transmission duty ratio value needs to be reduced; power backed beams and/or antenna panel quality.

With reference to the first aspect, in certain implementations of the first aspect, the target beam and/or target antenna panel is a beam and/or antenna panel to which the information of radiation intensity is associated.

Based on the above technical solution, when the reported radiation intensity information includes information associated with the radiation intensities of a plurality of beams, one or a part of the plurality of beams may be selected as a target beam. Or, when the reported radiation intensity information includes information related to radiation intensities of a plurality of antenna panels, one or a part of the antenna panels in the plurality of antenna panels may be selected as a target antenna panel.

With reference to the first aspect, in certain implementations of the first aspect, the radiation intensity information is reported based on one or more of: terminal device, single beam, single antenna panel.

Based on the above technical solution, taking the terminal device as an example, the terminal device may perform monitoring management by using the antenna panel or the beam as a unit, for example, the terminal device respectively maintains a set of management information for each activated beam or each activated antenna panel, that is, a monitoring management mechanism based on the beam or the antenna panel. Alternatively, the terminal device may perform monitoring management in units of all active antenna panels or beams, for example, the terminal device maintains a set of management information for all active beams or all active antenna panels, that is, a monitoring management mechanism based on beams or antenna panels. Or reporting may be performed in units of terminal devices, which is not limited herein.

With reference to the first aspect, in certain implementations of the first aspect, the method further includes: reporting support for default beam and/or antenna panel communications, or reporting support for indicated beam and/or antenna panel communications.

In a second aspect, a method of communication is provided. The method can be executed by the terminal device, or can also be executed by a chip or a chip system or a circuit configured in the terminal device; alternatively, the method may be performed by a network device, or may be performed by a chip or a chip system or a circuit configured in the network device, which is not limited in this application.

The method can comprise the following steps: determining whether a preset condition is met; and under the condition that a preset condition is met, performing communication by using the power-backed wave beam and/or the power-backed antenna panel.

Optionally, in the case that a preset condition is met, the information of the radiation intensity is not reported, and the power-backed beam and/or the power-backed antenna panel is used for communication.

Based on the above technical solution, signaling overhead, transmission delay, reliability, and complexity compromise are comprehensively considered, and the terminal device and the network device may use the beam and/or the antenna panel after power backoff to perform communication (such as data or signal transmission). Taking the terminal device as an example, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, if a certain condition is satisfied, the terminal device may not report the information of the radiation intensity, and continue to use the current beam and/or antenna panel for communication, i.e., use the power-backed beam and/or power-backed antenna panel for communication. Therefore, the radiation intensity can be prevented from exceeding the regulation limit, the signaling overhead can be reduced, and the transmission time delay can be reduced.

With reference to the second aspect, in certain implementations of the second aspect, the preset condition is one of: the adopted power back-off value is smaller than a first threshold; or the quality of the wave beam after the power return is optimal, and/or the quality of the antenna panel after the power return is optimal; or the quality of the wave beam after the power return is larger than a second threshold, and/or the quality of the antenna panel after the power return is larger than a third threshold; alternatively, the channel capacity is greater than the fourth threshold.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a fifth generation (5G) system or a New Radio (NR), a Long Term Evolution (LTE) system, a Frequency Division Duplex (FDD) system, a Time Division Duplex (TDD) system, a Universal Mobile Telecommunications System (UMTS), and the like. The technical scheme of the embodiment of the application can also be applied to device-to-device (D2D) communication, machine-to-machine (M2M) communication, Machine Type Communication (MTC), and communication in a vehicle networking system.

For the understanding of the embodiments of the present application, a communication system suitable for the embodiments of the present application will be described in detail with reference to fig. 1.

Fig. 1 is a diagram of a wireless communication system 100 suitable for use in embodiments of the present application. As shown in fig. 1, the wireless communication system 100 may include at least one network device, such as the network device 111 shown in fig. 1, and the wireless communication system 100 may further include at least one terminal device, such as the terminal devices 121 to 123 shown in fig. 1. The network equipment and the terminal equipment can be both provided with a plurality of antennas, and the network equipment and the terminal equipment can communicate by using a multi-antenna technology. The network device can be used as a sending end, and the terminal device can be used as a receiving end; alternatively, the network device may serve as a receiving end, and the terminal device may serve as a transmitting end.

It is understood that the transmission between the network device and the terminal device may be transmitted through radio waves, or may be transmitted through transmission media such as visible light, laser, infrared, optical fibers, and the like.

It should be understood that fig. 1 is merely an exemplary illustration and the present application is not limited thereto. For example, the embodiments of the present application may also be applied to any communication scenario including a transmitting end and a receiving end.

It should also be understood that the network device in the wireless communication system may be any device having a wireless transceiving function. Such devices include, but are not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (Node B, NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (e.g., Home evolved NodeB, or Home Node B, HNB), BaseBand Unit (Base band Unit, BBU), Access Point (AP) in Wireless Fidelity (WIFI) system, etc., and may also be 5G, such as NR, gbb in system, or TRP, transmission Point (TRP or TP), one or a group of antennas (including multiple antennas, NB, or a transmission panel) of a Base Station in 5G system, such as a baseband unit (BBU), or a Distributed Unit (DU), etc.

In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may further include an Active Antenna Unit (AAU). The CU implements part of the function of the gNB and the DU implements part of the function of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of a Radio Resource Control (RRC) layer and a Packet Data Convergence Protocol (PDCP) layer. The DU is responsible for processing a physical layer protocol and a real-time service, and implements functions of a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a Physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing and active antenna related functions. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as the RRC layer signaling, may also be considered to be transmitted by the DU or by the DU + AAU under this architecture. It is to be understood that the network device may be a device comprising one or more of a CU node, a DU node, an AAU node. In addition, the CU may be divided into network devices in an access network (RAN), or may be divided into network devices in a Core Network (CN), which is not limited in this application.

It should also be understood that terminal equipment in the wireless communication system may also be referred to as User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like. The embodiments of the present application do not limit the application scenarios.

To facilitate understanding of the embodiments of the present application, the terms and contexts referred to in the present application will first be briefly described below.

When the terminal device is used, the transmitting antenna is relatively close to the brain or other parts of the human body, and in order to avoid emitting too much electromagnetic energy radiation, the transmitting antenna is generally expressed by some standards so as to ensure that the electromagnetic energy radiation is not too much, and the safety of people using the terminal device is guaranteed. For example, maximum permissible radiation (MPE), or radio frequency radiation maximum permissible values (RF exposure), or Specific Absorption Rate (SAR), or radio frequency radiation (RF emission), etc. may be used to represent that the constraints on the radiation requirements of the human body are satisfied. Hereinafter, for the sake of understanding, description will be mainly made with MPE as an example.

Typically the MPE constraint index is the average amount of area radiation over the average time at a distance. As to the specific constraint requirements, reference may be made to the constraint requirements given by the international commission on non-ionizing radiation protection (ICNIRP) and the Federal Communications Commission (FCC). By way of illustration, tables 1 and 2 show two possible ways of constraining.

Table 1 shows a simple way of constraining, i.e. taking into account the frequency (f)_ref) Power Density (PD), statistical area, and statistical time. In practice, the MPE constraints will also typically take into account body distance and antenna array factors, as shown in Table 2.

As shown in table 2, for example, when a 2 × 2 antenna array is deployed and the area of the array (array area) is 9cm, the frequency f is 10GHz²When the distance d between a terminal device (such as portable applications) and a human body is 0.5cm, the ICNIRP constraint is met, the maximum transmitted power (maximum transmitted power) is 13dbm,the maximum Equivalent Isotropic Radiated Power (EIRP) (or effective isotropic EIRP) is 24 dBm. The example does not consider time averaging and the terminal device can be considered to transmit continuously.

TABLE 1

TABLE 2

The MPE constraints take into account the amount of radiation over the average time, so when radiation is not sustained, the amount of radiation can increase. Taking table 2 as an example, the given transmission power and EIRP constraint are both indexes under continuous transmission, that is, indexes with a duty cycle (or duty ratio) of 100%; if the uplink transmission duty cycle decreases over a period of time, the corresponding transmit power or EIRP may increase. For example, if the uplink transmission duty cycle is reduced to 25% over a period of time (e.g., under TDD typical matching DDDSU), the corresponding transmit power or EIRP may be increased by 6 dB.

As can be seen from the above analysis, the MPE constraint considers many factors, such as distance from the human body, transmission power, EIRP, uplink transmission duty ratio (or transmission time ratio), and the like. These factors are entirely implementation-dependent on the terminal device. For example, the body distance may be obtained by a sensor; as another example, transmit power or EIRP may be implemented with power backoff; for another example, the uplink transmission duty cycle may be configured reasonably by reporting the capability to the network device, and so on. However, the implementation by a simple terminal device may bring certain problems and risks to the system. For example, power backoff may cause uplink coverage collapse and may also result in Radio Link Failure (RLF) risk of the system; as another example, an uplink transmission duty cycle that is too low may result in an uplink throughput that is too low. In addition, sensors that detect human body distance also face accuracy and precision issues, among other things.

The above briefly introduces the relevant information about MPE constraints and the following introduces the relevant content of using beam communication.

In some communication systems, such as 5G NR, high frequency bands (generally considered to be above 6 GHz) are newly added, such as 28GHz, 39GHz or 60GHz bands. The introduction of the high frequency band can realize larger bandwidth and higher transmission rate. The introduction of high frequency bands may cause severe fading of the signal during spatial propagation due to the high frequency. For example, a Beamforming (BF) technique may be used to obtain a good directional gain, so as to increase directional power in the transmission direction, improve signal to interference plus noise ratio (SINR) at the receiving end, and further improve system performance.

In the 5G NR research process, considering cost and performance comprehensively, a Hybrid Beamforming (HBF) technique including digital beamforming and analog beamforming may be adopted. In the implementation of beamforming technology, the core component includes an antenna panel (antenna panel), and a beam is transmitted or received through the antenna panel. In the implementation of 5G NR deployment, because directional beams are used, in order to satisfy wide area coverage, both the network device and the terminal device are deployed by using multiple antenna panels. Especially for terminal equipment, antenna panel deployment is more important to the performance impact in order to meet coverage, and with limited space and cost savings.

After the network device and the terminal device both adopt the hybrid beamforming technology, some discussion is brought about.

1. Regarding transmit and receive beam management.

With respect to transmit and receive beam management, the content of beam management is finally standardized in the first release 3GPP Rel-15 of 5G NR, through several discussions. The framework of beam management is standardized, including beam training, beam measurement and reporting, individual signal or channel beam indication, etc. The uplink and downlink signals or channel beam indications are briefly described below, respectively.

For example, for a Physical Downlink Control Channel (PDCCH) beam indication, a beam resource pool may be configured by using higher layer Radio Resource Control (RRC) signaling, and one of the beams may be activated by medium access control-control element (MAC-CE) signaling to indicate a PDCCH beam. For another example, for a Physical Downlink Shared Channel (PDSCH) beam indication, a beam resource pool may be configured by using higher layer RRC signaling, a beam subset including a plurality of beams is activated by MAC-CE signaling, and finally a beam of the beam subset is triggered by Downlink Control Information (DCI) to indicate a PDSCH beam. As another example, for periodic and aperiodic channel state information reference signal (CSI-RS) beams, it may be indicated through RRC signaling. As another example, for a semi-persistent CSI-RS beam, this may be indicated by the MAC-CE. For another example, for a Physical Uplink Control Channel (PUCCH) beam indication, a beam resource pool may be configured by using higher layer RRC signaling, and one of the beams may be activated by MAC-CE signaling to indicate a PUCCH beam. As another example, for a Physical Uplink Shared Channel (PUSCH) beam indication, a Sounding Reference Signal (SRS) beam indication may be indicated by an SRI associated therewith. As another example, beam indications for periodic SRS (P-SRS) and aperiodic SRS (AP-SRS) may be indicated by RRC signaling. As another example, for semi-persistent SRS (SP-SRS), RRC signaling may be employed or may be indicated through MAC-CE signaling.

It should be understood that the related contents regarding the management of the transmitting and receiving beams are only for easy understanding of the description, and do not limit the protection scope of the embodiments of the present application.

2. Regarding the antenna panel.

In the above-mentioned signal or channel beam indication process, the switching of the beam (or beam pair) is a core process, and not only relates to the beam switching of the network device, but also relates to the beam switching of the terminal device. In the 3GPP Rel-15 release, the antenna panel is not explicitly defined, and the antenna panel of the network device or the antenna panel of the terminal device, respectively, is transparent. The transparency can be understood as that the network device antenna panel status terminal device is not visible, and similarly, the network device antenna panel status terminal device is also not visible, depending on the respective implementation. Therefore, how the beams or resources (signals or channels, etc.) are associated with the antenna panel also depends substantially on the device implementation. When the network device notifies the terminal device to switch the beam, the network device cannot determine whether the terminal device switches the antenna panel during the switching process of the beam because the antenna panel is transparent. Switching the antenna panel includes two actions, antenna panel activation and antenna panel switching. In addition, it takes a certain time to switch the antenna panel regardless of the terminal device or the network device. RAN4 proposals have discussed and agreed that switching antenna panels typically requires around 2-3ms (including antenna panel activation and antenna panel switching). In most scenes of the current protocol, the time for switching the antenna panel is not reserved, so that when the beam switching occurs, if the antenna panel needs to be switched, enough time is reserved by relying on a system main control node to complete the switching of the antenna panel by the network equipment or the terminal equipment.

Antenna panels, panel for short. Each antenna panel may be configured with one or more receive beams and one or more transmit beams. Thus, an antenna panel may also be understood as a beam group. A communication device, such as a terminal device or a network device, may receive signals via a receive beam on an antenna panel or may transmit signals via a transmit beam on the antenna panel.

The antenna panel is a logical entity and how physical antennas are mapped to the logical entity is determined by the product implementation. An antenna panel Identifier (ID) is defined such that at least the transmitting antenna panel of the terminal device is visible to the network device, so that the network device can indicate or obtain the terminal device antenna panel status based on the ID of the antenna panel.

An antenna panel may also be implicitly identified by a certain signal or a certain set of signals. Such as may be represented by constraining some transmission properties of the signal and the set of signals. For example, in the Rel-15 protocol, the behavior of restricting SRS resource sets (SRS resource sets) "SRS resources belonging to the same SRS resource set cannot be transmitted simultaneously, and SRS resources belonging to different SRS resource sets can be transmitted simultaneously" shows that beams of the same antenna panel cannot be transmitted simultaneously, and beams of different antenna panels can be transmitted simultaneously.

For example, one antenna panel may correspond to one SRS resource set ID, that is, one SRS resource set ID may be used to indicate one antenna panel. Alternatively, the ID of the antenna panel may be directly associated with the reference signal resource or the set of reference signal resources. Alternatively, the ID of the antenna panel may be allocated for a target reference signal resource or a set of reference signal resources. Alternatively, the ID of the antenna panel may be additionally configured in spatial relationship (spatial relationship) information.

In addition, aiming at the receiving and sending of the single antenna panel, the terminal equipment is simple to realize, the power consumption and the heat dissipation are low, and the management of the panel is simple; but a certain time (such as 2-3ms) is required to be reserved when the panel is activated and switched, so that the system efficiency is reduced; the antenna panels are simultaneously transmitted and received, the robustness of the system is strengthened, and the system efficiency can be improved; however, the complexity of terminal device implementation is increased, and the problems of large power consumption and heat dissipation are caused.

It should be understood that the related contents of the antenna panel are only for easy understanding, and do not limit the protection scope of the embodiments of the present application. For example, in future protocols, when the ID of the antenna panel is improved, the method is still applicable to the embodiment of the present application.

3. MPE constraints for the end devices.

The embodiment of the application mainly concerns MPE constraint of terminal equipment.

As mentioned above, FCC and ICNIRP have certain constraints on terminal device radiation, such as the radiated power or energy per centimeter at a certain distance from a person should be less than a certain value.

In the 3GPP Rel-15 release, MPE is discussed more at the RAN4, since it involves more index constraints. In Rel-15, the RAN4 presents two static solutions, power backoff and uplink transmission duty cycle reporting. The terminal device may be implemented by considering a power backoff mode or an uplink transmission duty ratio reporting mode respectively according to specific implementations, or by combining the two modes. Some possible examples are as follows.

For example, the terminal device returns the power to meet the MPE constraint under the premise that the uplink transmission duty ratio reporting is 100% in consideration, so that the terminal device meets the MPE constraint at any time. For another example, the terminal device reports the uplink transmission duty ratio to satisfy the MPE constraint under the premise of considering the maximum transmission power or the EIRP, and the terminal device may satisfy the MPE constraint without power backoff in the uplink transmission duty ratio. For another example, the terminal device reports and improves the uplink transmission duty ratio while considering the maximum transmission power or the EIRP, and if the MPE constraint is not satisfied, the terminal device needs to back off the power in the uplink transmission duty ratio, and the MPE constraint can also be satisfied.

Furthermore, the RAN4 defines an MPE evaluation period of 1s at Rel-15, and the end device can evaluate MPE cases for any 1s period, depending on the implementation.

Since Rel-15 provides a static scheme, the static scheme does not adapt well to changing channel environments. Therefore, RAN4 further addresses the need for a dynamic solution to solve the MPE problem at Rel-16. Rel-16 considers the scope of solving the MPE problem to be solving the radio link failure caused by MPE. The method mainly focuses on two aspects, namely reporting the current MPE state of the terminal equipment and reporting the future MPE state (margin and prediction) of the terminal equipment. The realizable modes comprise: and reporting the uplink transmission duty ratio or reporting the power back-off value. The RAN4Rel-16 scheme is mainly that MPE states of terminal equipment are reported to network equipment through the terminal equipment, and then the network equipment can be scheduled under the consideration of MPE constraint. Meanwhile, the MPE problem when selecting uplink transmission based on a Multi-antenna panel (Multi-panel) is discussed in Rel-16RAN 1.

In Rel-17RAN1FeMIMO WID, MPE problem is also proposed, and the writing method is to consider the problem of uplink coverage loss caused by MPE constraint when the verification and standardization selects uplink transmission based on Multi-panel.

As can be seen from the above, in the existing solutions, the MPE constraints for the terminal device mainly include two solutions: static schemes and dynamic schemes.

1) A static scheme.

Specifically, Rel-15 defines a set of static solutions to solve the MPE problem. The scheme relates to two sub-schemes, which can be implemented independently or jointly, depending on the network device configuration and the terminal device implementation.

The first sub-scheme is as follows: a static UE capability is defined that limits the maximum uplink transmission duty cycle. The transmission time through the control terminal satisfies the MPE index constraint, a format as shown below.

[[

maxUplinkDutyCycle-FR2 ENUMERATED{n15，n20，n25，n30，n40，n50，n60，n70，n80，n90，n100}OPTIONAL

]]

And the second sub-scheme is as follows: a power backoff mechanism is defined to manage the maximum power reduction (P-MPR). And the MPE index constraint is met by controlling the uplink transmission power.

The two sub-schemes can respectively and independently solve the MPE problem, and the MPE problem can be combined to meet MPE index constraint.

For example, if maxuplinkdtycycle-FR 2 reports in the first sub-scheme, and when the uplink transmission duty ratio of the terminal device in any 1s evaluation period is greater than the capability report value, the terminal device performs power backoff according to uplink scheduling, that is, P-MPR. For another example, if maxuplinkdtycycle-FR 2 is not reported in the first sub-scheme, the terminal device may directly satisfy the MPE constraint through power backoff.

2) And (4) dynamic scheme.

Rel-16 proposes some MPE reporting schemes, as follows.

As an example, when an MPE problem occurs, the terminal device reports a beam or a panel for transmitting data after considering the MPE problem. As another example, when an MPE problem occurs, the terminal device carries a reporting base beam or panel through the PHR, or based on a terminal device power back-off value. As yet another example, the terminal reports power headroom or energy headroom. In another example, the terminal device reports MPE alarm signaling: such as an alert message by RRC or 'P' bit of MAC-CE. For another example, the terminal device reports the uplink transmission duty ratio. The network device can calculate and decide the next scheduling condition through the report of the terminal device.

Although the static scheme can ensure that the terminal equipment always confirms to meet MPE constraint, the use range of the terminal equipment is limited, and the dynamic scene cannot be met. Although the dynamic scheme can meet the dynamic scene, the dynamic signaling is added, the reporting reliability after MPE occurs is poor, and the transmission delay can be generated.

In view of this, in the embodiment of the present application, compromise between signaling overhead, transmission delay, reliability, and complexity is comprehensively considered, and an uplink transmission enhancement method based on radiation intensity constraint is implemented.

Various embodiments provided herein will be described in detail below with reference to the accompanying drawings.

Fig. 2 is a schematic interaction diagram of a method 200 of communication according to an embodiment of the present application. The method 200 may include the following steps.

210, communicating using a target beam and/or a target panel, wherein the target beam is a default beam and/or the target antenna panel is a default antenna panel; alternatively, the target beam is the indicated beam, and/or the target antenna panel is the indicated antenna panel, and the indicated beam is one or more of the candidate beams, and the indicated antenna panel is one or more of the candidate antenna panels.

For convenience of understanding, the following embodiments mainly take a scenario in which the terminal device communicates with the network device using the target beam and/or the target panel as an example, and it should be understood that the scheme described in the embodiments of the present application may also be used when the network device communicates with the terminal device using the target beam and/or the target panel.

Optionally, the terminal device may report the capability information, and the capability item may include: { MPE transmission capability supporting default MPE transmission, MPE transmission capability supporting indication }. Accordingly, the network device may indicate the configuration, which may include, for example: { MPE transmission capability supporting default MPE transmission, MPE transmission capability supporting indication }. For example, the terminal device may report capability information, and the capability information indicates that the terminal device supports a default transmission capability or a default MPE transmission, that is, the terminal device may use a default beam and/or panel for communication. For another example, the terminal device may report capability information, and indicate that the terminal device supports the indicated transmission capability or the indicated MPE transmission through the capability information, that is, the terminal device may use the indicated beam and/or panel for communication. For another example, the terminal device may report capability information, and indicate, through the capability information, that the terminal device supports both default MPE transmission and indicated MPE transmission capability.

In a possible implementation manner, the target beam may be a beam indicated by the network device to the terminal device; and the target panel can be a panel indicated by the network equipment to the terminal equipment. Taking a panel as an example, the indicated panel can be one or more panels specified from the candidate panels. The candidate panel may be a panel that is activated by the terminal device, or may be a plurality of panels that are agreed in advance or indicated in advance or configured in advance, which is not limited herein. In yet another possible implementation, the target beam may be a default beam; the target panel, may be a default panel. The following is mainly exemplified by default beams and default panel.

Taking a beam as an example, the default beam may include one beam, or the default beam may include a plurality of beams.

The default beam, or agreed-upon beam, represents a pre-agreed beam, or a beam prescribed by a protocol, or a beam that does not require explicit indication by the network device or used by the current communication. It is to be understood that when the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limit, the network device does not need to indicate to the terminal device specific information of the beam used for transmitting data, the terminal device may transmit data using a default beam, and accordingly, the network device receives data using the corresponding beam.

Taking a panel as an example, the default panel can include one panel, or the default panel can include a plurality of panels.

The default panel, or contracted panel, may represent a pre-contracted panel, or a panel specified by the agreement, or a panel not explicitly indicated by the network device or currently used for communication. For example, when the radiation intensity of the terminal device exceeds a regulatory limit or is about to exceed the regulatory limit, the network device does not need to indicate to the terminal device specific information of a panel used for transmitting data, the terminal device may transmit data using a default panel, and accordingly, the network device receives data using the corresponding panel.

Based on the embodiment of the application, signaling overhead, transmission delay, reliability and complexity compromise are comprehensively considered, and the terminal device can use a default beam and/or a default panel to perform communication (such as sending uplink data or signals). For example, when the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limit, a default beam and/or a default panel may be used for communication (e.g., sending uplink data or signals, etc.), so that not only the radiation intensity exceeding the regulatory limit may be avoided, but also uplink transmission enhancement based on the radiation intensity constraint may be implemented.

There are many standards for characterizing the radiation intensity, the embodiment of the present application mainly uses MPE as an example for illustration, and other standards that can characterize the radiation intensity can use the solution of the embodiment of the present application. In the following examples where MPE problems occur or MPE risks are experienced, the skilled person will understand the meaning, which is used to indicate that the radiation intensity exceeds a regulatory limit, or that the radiation power or energy of the terminal device does not meet a law or statute or regulation.

It should be understood that the embodiments of the present application mainly use the example that the terminal device uses the beam and/or the panel to communicate with the network device, which is not limited to this. For example, at low frequencies, the terminal device may communicate with the network device using an antenna. In a low frequency radiation constraint scenario, the solution of the embodiments of the present application may also be used, such as using a default or indicated antenna for communication.

Optionally, before step 210, the method 200 may further include step 201.

And 201, the terminal equipment reports the information of the radiation intensity.

After the terminal device reports the radiation intensity information, whether to use a default beam and/or a default panel to communicate with the network device can be determined according to the existence of a response received from the network device or according to the content of a response message sent by the network device; or after the terminal equipment reports the information of the radiation intensity, the terminal equipment uses a default beam and/or a default panel to communicate with the network equipment; or after the terminal equipment reports the information of the radiation intensity, the terminal equipment uses a default wave beam and/or a default panel to communicate with the network equipment after a period of time; or determining to use a default beam and/or a default panel according to the content of a response message sent by the network equipment, and communicating with the network equipment by using the default beam and/or the default panel after a period of time; this is not limitative.

The following examples describe the information on the intensity of the radiation in detail.

Alternatively, the embodiments of the present application may include at least the following scheme 1 and scheme 2.

In scheme 1, a terminal device reports radiation intensity information and communicates with a network device by using a target beam and/or a target panel, as in step 201;

and in the scheme 2, the terminal equipment does not report the information of the radiation intensity and uses the beam and/or the panel used by the current communication to communicate with the network equipment.

Scheme 1 and scheme 2 are described in detail below.

In the scheme 1, the terminal equipment reports the information of the radiation intensity and uses a target beam and/or a target panel to communicate with the network equipment.

The following mainly takes the target beam and/or the target panel as the default beam and/or the default panel as an example for illustration. That is, according to scheme 1, the terminal device reports the radiation intensity information, and communicates with the network device using a default beam and/or a default panel.

Optionally, the terminal device reports the radiation intensity information when a certain condition is met.

For example, in a case where the quality of the beam and/or the panel after the power backoff is not optimal, the terminal device reports the information of the radiation intensity.

For another example, the terminal device reports the radiation intensity information if the power-backed beam and/or panel quality is less than threshold # 5. The threshold #5 may be used for the terminal device to determine whether the radiation intensity information needs to be reported. If the beam and/or the panel quality after the power return is larger than the threshold #5, the terminal equipment does not need to report the information of the radiation intensity; if the beam and/or panel quality after the power backoff is smaller than the threshold #5, the terminal device needs to report the information of the radiation intensity. The case of equality is not limited.

The threshold #5 may be a numerical value or a condition, and is not limited. For example, threshold #5 may be a predefined value, such as a protocol predefined value, or a network device configuration notification value; alternatively, the value may be determined from the historical communication situation, and is not limited thereto.

For another example, when the power back-off value adopted by the terminal device is greater than the threshold #6, the terminal device reports the radiation intensity information. The threshold #6 may be used for the terminal device to determine whether the radiation intensity information needs to be reported. If the power back-off value is smaller than the threshold #6, the terminal equipment does not need to report the information of the radiation intensity; if the power back-off value is greater than the threshold #6, the terminal device needs to report the radiation intensity information. The case of equality is not limited.

The threshold #6 may be a numerical value or a condition, and is not limited. For example, threshold #6 may be a predefined value, such as a protocol predefined value, or a network device configuration notification value; alternatively, the value may be determined from the historical communication situation, and is not limited thereto.

In another example, when the terminal device determines that the communication environment satisfies a certain condition, the terminal device reports the radiation intensity information. For example, if the channel capacity is smaller than the threshold #7, the terminal device reports the radiation intensity information. The threshold #7 may be used for the terminal device to determine whether the radiation intensity information needs to be reported. If the channel capacity is larger than the threshold #7, the terminal equipment does not need to report the information of the radiation intensity; if the channel capacity is smaller than the threshold #7, the terminal device needs to report the radiation intensity information. The case of equality is not limited.

The threshold #7 may be a numerical value or a condition, and is not limited. For example, threshold #7 may be a predefined value, such as a protocol predefined value, or a network device configuration notification value; alternatively, the value may be determined from the historical communication situation, and is not limited thereto.

As yet another example, the terminal device may periodically report information of the radiation intensity.

It is to be understood that the above conditions are exemplary only and not limiting.

The details of the information about the radiation intensity reported by the terminal device are described in detail below.

In a possible case, the terminal device sends information of the radiation intensity to the network device and, after receiving the response message of the network device, communicates with the network device using a default beam and/or a default panel.

The response message is, for example, an Acknowledgement (ACK) message. The network device may perform ACK acknowledgement on the information of the radiation intensity reported by the terminal device, for example, confirm that the information of the radiation intensity is successfully received by a New Data Indicator (NDI) flipping method in the DCI. After receiving the message, the terminal device communicates with the network device using a default beam and/or a default panel.

As another example, the response message may be carried in control information, and the terminal device is instructed to use a default beam and/or a default panel to communicate with the network device by 1 bit (bit) or multiple bits in the control information.

It should be understood that the above is illustrative only and not limiting. For example, there is still another possible case that when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the terminal device sends the information of the radiation intensity to the network device, and if the terminal device does not receive a negative-acknowledgement (NACK) of the network device within a certain time period, the terminal device communicates with the network device using a default beam and/or a default panel.

It should also be understood that the embodiment of the present application mainly uses the ACK message as an example for illustration, which is not limited to this, and other ways that can confirm the successful reception of the radiation intensity fall within the scope of the embodiment of the present application.

It should also be understood that the above description is made with reference to default beams and/or default panel as examples. A scheme is also achievable in which the target beam is the indicated beam, and/or the target panel is the indicated panel. In a possible implementation manner, the network device may also display, through 1 bit or multiple bits in the control information, a beam and/or a panel used by the terminal device. By the mode, the network equipment can select the proper beam and/or panel for the terminal equipment according to the actual communication situation, so that the beams of the terminal equipment and the network equipment can be aligned, and the communication performance can be improved.

Specific implementations are described below in connection with default beams and default panel possible forms.

Assume that the terminal device has N activated beams, M activated panels, and N, M is an integer greater than 1 or equal to 1, e.g., N, M is each greater than 1.

It should be understood that in the examples of the present application, N and M are not strictly defined. For example, the embodiments of the present application may be described based on that the beam activated by the terminal device is N beams, that is, the terminal device may use the target beam to perform communication when the beam activated by the terminal device is N beams. For another example, in the embodiment of the present application, the description may be performed for M panels based on the panel that is activated by the terminal device, that is, the terminal device may use the target panel to perform communication when the panel that is activated by the terminal device is the M panels. For another example, in the embodiment of the present application, the description may be performed based on that the activated beam of the terminal device is N beams and the activated panel is M panels, that is, when the activated beam of the terminal device is N beams and the activated panel is M panels, the terminal device may use the target beam on the target panel to perform communication, and at this time, N and M may be equal, or M may be greater than N.

Taking a panel as an example, the default panel can be in the form of any one or more of the following.

Format 1, the default panel is the panel with the best quality panel.

That is, the terminal device may transmit data using the best quality of the activated panel by default, and accordingly, the network device receives data using the corresponding panel.

It should be understood that under form 1, a panel with the best quality panel can mean that the panel is the panel with the best quality panel among the M panels; alternatively, it can mean that the panel is the best panel meeting certain criteria; alternatively, the expression may be a plurality of panels, and the panel is preferable when a certain criterion is satisfied; alternatively, it can also mean that only the panel meets a certain threshold requirement.

It is assumed that the panel activated by the terminal device includes panel #1, panel #2, panel #3, and panel #4, and the panel currently communicated by the terminal device (or the panel to be used by the terminal device, such as the panel used by the network device to schedule the terminal device for data to be transmitted) is panel # 1. When the radiation intensity of the terminal equipment exceeds the regulation limit or is about to exceed the regulation limit, the terminal equipment can take some measures to prevent the radiation intensity of the terminal equipment from exceeding the regulation limit, for example, the terminal equipment can perform power back-off on currently used panel #1 (or panel #1 to be used). In addition, the terminal equipment can perform beam measurement to determine the panel with the optimal quality.

In the embodiments of the present application, the quality of a panel is referred to several times, and it is understood that the quality of a panel may refer to the quality of the panel, and may also refer to the quality of a beam on the panel. For example, the quality of a panel may be optimal, which means that the quality of the panel is optimal among a plurality of panels, or that the quality of a beam used for communication on the panel among a plurality of beams is optimal.

Beam measurement, i.e., obtaining beam quality information by measuring reference signals (such as SRS, CSI-RS, but not limited to the above reference signals) associated with a beam, parameters for measuring beam quality include, but are not limited to, Reference Signal Receiving Power (RSRP). For example, the beam quality can also be measured by parameters such as Reference Signal Reception Quality (RSRQ), signal-to-noise ratio (SNR), signal-to-interference plus noise ratio (SINR), and the like. For this reason, the following description is omitted.

In one possible case, the quality of the panel #1 is optimal, i.e. the quality of the panel #1 is still optimal after the power has been backed off.

In this case, the terminal device can continue to transmit data using the power-backed panel # 1. In this case, the terminal device may not report the information of the radiation intensity, that is, the terminal device does not report the information of the radiation intensity, and transmit data using the panel #1 with the power returned.

In a specific example, as shown in fig. 3, before the MPE problem is considered by the terminal device, the quality of panel #1 is the best and the quality of panel #4 is the worst. After the terminal device considers the MPE problem, the panel with the optimal quality is still the panel #1, and then the terminal device can not trigger the MPE problem reporting. The network device and the terminal device use the currently scheduled or protocol-constrained transceiving beam pair on the panel #1 by default to transceive the PUSCH.

There are many ways for the terminal device to determine the quality of each panel or beam, and this is not a limitation. For example, as shown in fig. 3, a terminal device measures a downlink beam quality (DL beam quality) and derives an uplink beam quality or an uplink panel quality from the downlink beam quality. For another example, the terminal device may transmit according to a beam or a panel indicated by the network device, and further determine the panel or the beam quality after there is no power control estimation of the MPE. It should be understood that any way in which the terminal device can be made aware of the panel or beam quality is suitable for use in embodiments of the present application. For this reason, the following description is omitted. For convenience of description, the following description mainly takes the example that the terminal device measures the downlink beam quality and derives the uplink beam quality or the uplink panel quality according to the downlink beam quality.

Yet another possible scenario is that the quality of panel #1 is not optimal, i.e. the quality of panel #1 after power back is not optimal.

In this case, the terminal device reports the radiation intensity information to the network device. The network device determines that the radiation intensity of the terminal device exceeds or is about to exceed the regulation limit according to the information of the radiation intensity.

As an example, a pre-agreement or protocol provides that when the radiation intensity of the terminal device exceeds or is about to exceed a regulatory limit, the best quality of the activated panel is used to transmit data. Then, when the network device determines that the radiation intensity of the terminal device exceeds the regulation limit or is about to exceed the regulation limit, the network device configures the terminal device to transmit data by using the panel with the best quality. And the network device may perform ACK acknowledgement on the information of the radiation intensity reported by the terminal device, for example, confirm that the information of the radiation intensity is successfully received by using an NDI flipping method in DCI. And after receiving the message, the terminal equipment uses the panel with the best quality in the activated panels to send data according to the scheduling of the network equipment.

As yet another example, when the network device determines that the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limit, the network device configures the terminal device to transmit data using the best quality panel. And the network equipment sends a response message to the terminal equipment, so as to inform the terminal equipment of adopting the panel with the best quality to send data. For example, this may be achieved by a 1-bit field. If the bit field takes a value of "1", it indicates that the terminal device can use the panel with the best quality to send data; the value of the bit field is "0", which indicates that the terminal device continues to use the current panel to transmit data.

It should be understood that the above two examples are only illustrative and not limiting. For example, after receiving the information about the radiation intensity of the terminal device, the network device may not send a message to the terminal device, and the terminal device may not receive a message for a certain period of time, and may default that the network device agrees to send data according to the best quality panel.

A specific example is shown in fig. 4. The terminal equipment measures the quality of the downlink wave beam, deduces the quality of the uplink wave beam or the quality of the uplink wave beam according to the quality of the downlink wave beam, and before the terminal equipment considers the MPE problem, the quality of the wave beam #1 is optimal, and the quality of the wave beam #4 is worst. After the MPE problem is considered by the terminal equipment, the panel with the optimal quality is changed into a panel #2, and then the MPE problem can be reported by the terminal equipment. The network equipment knows that the terminal equipment has MPE problem, and the network equipment and the terminal equipment use a suboptimal panel #2 transceiving beam pair to transceive PUSCH by default.

Based on the above form 1, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the terminal device may default to use the panel with the best quality to communicate with the network device, so that not only the beams of the terminal device and the network device may be aligned, but also the transmission performance may be improved by using the panel with the best quality to communicate, and the signaling overhead may be reduced, and the transmission delay may be reduced.

Format 2, the default panel includes the panel of the M panels having a panel mass greater than the threshold # 1.

That is, the terminal device may transmit data by default using a panel of which the quality is greater than the threshold #1 among the activated panels, and accordingly, the network device receives data using the corresponding panel. For example, if a single panel meets a certain threshold requirement (e.g., quality greater than threshold #1), then the default panel is that panel.

The threshold #1 may be used for the terminal device to determine whether a certain panel can be used to transmit data. If the quality of a certain panel is greater than the threshold #1, the panel can be used for sending data; if the quality of a certain panel is less than the threshold #1, the panel is not used to transmit data. The case of equality is not limited. For example, when the quality of a certain panel is equal to the threshold #1, the panel may be used to transmit data, or the panel may not be used to transmit data.

The threshold #1 may be a numerical value, or may be a condition or a criterion, and is not limited. For example, threshold #1 may be a predefined value, such as a protocol predefined value, or a network device configuration notification value; alternatively, the value may be determined from the historical communication situation, and is not limited thereto.

It is assumed that the panel activated by the terminal device includes panel #1, panel #2, panel #3, and panel #4, and the panel currently communicated by the terminal device (or the panel to be used by the terminal device, such as the panel used by the network device to schedule the terminal device for data to be transmitted) is panel # 1.

When the radiation intensity of the terminal equipment exceeds the regulation limit or is about to exceed the regulation limit, the terminal equipment can take some measures to prevent the radiation intensity of the terminal equipment from exceeding the regulation limit, for example, the terminal equipment can perform power back-off on currently used panel #1 (or panel #1 to be used). In addition, the terminal device may perform beam measurements to determine a panel with a quality greater than threshold # 1.

One possible scenario is that the only panel with a quality greater than the threshold #1 is panel #1, i.e. the quality of panel #1 after power back is greater than the threshold # 1.

In another possible case, the panel with the quality greater than the threshold #1 includes panel #2 and panel #3, i.e., the quality of both panel #2 and panel #3 after the power backoff is greater than the threshold # 1.

As an example, a pre-agreement or protocol provides that when the radiation intensity of the terminal device exceeds or is about to exceed a regulatory limit, data is transmitted using a panel with a quality greater than a threshold # 1. Then, when the network device determines that the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the network device configures the terminal device to transmit data using a panel with quality greater than the threshold # 1. And the network device may perform ACK acknowledgement on the information of the radiation intensity reported by the terminal device, for example, confirm that the information of the radiation intensity is successfully received by using an NDI flipping method in DCI. After receiving the ACK message, the terminal device uses a panel with quality greater than threshold #1 to transmit data according to the scheduling of the network device, for example, uses panel #2 and panel #3 to transmit data.

As yet another example, when the network device determines that the radiation intensity of the terminal device exceeds or is about to exceed a regulatory limit, the network device configures the terminal device to transmit data using a panel with a quality greater than a threshold # 1. And the network equipment sends a response message to the terminal equipment, wherein the response message is used for informing the terminal equipment of sending data by using the panel with the quality greater than the threshold # 1. For example, this may be achieved by a 1-bit field. If the bit field takes a value of "1", it indicates that the terminal device can use a panel with quality greater than threshold #1 to transmit data; the value of the bit field is "0", which indicates that the terminal device continues to use the current panel to transmit data. For another example, the network device may also send information of the threshold #1 to the terminal device, and the terminal device determines to send data using a panel with quality greater than the threshold #1 based on the information of the threshold #1, such as sending data using panel #2 and panel # 3.

As a specific example, as shown in fig. 5, the network device and the terminal device use a transceiving beam pair of panel with quality greater than threshold #1 by default to transceive PUSCH. For the terminal device, the terminal device measures the downlink beam quality (DL beam quality), and derives the uplink beam quality or the uplink panel quality according to the downlink beam quality. Suppose that the quality of panel #1 is the best and the quality of panel #4 is the worst before the MPE problem is considered by the terminal equipment. For the terminal equipment, after the terminal equipment considers the MPE problem, namely after the power back-off value of the panel is considered, the panel with the optimal quality is judged to be the panel #2, and the panel with the quality larger than the threshold #1 comprises the panel #2 and the panel #3, so the PUSCH is transmitted by using the panel #2 and the panel # 3. For the network device, after knowing that the terminal device has the MPE problem, if the terminal device triggers the MPE problem reporting (that is, the terminal device reports the MPE problem), the network device can know, through measurement, that the panel whose quality is greater than the threshold #1 includes a panel #2 and a panel #3, and thus, the panel corresponding to the panel #2 and the panel #3 is used to receive the PUSCH.

In this embodiment, for the terminal device, the terminal device may know the beam quality (i.e., uplink beam quality) (or panel quality) at least in any one of the following manners. The beam quality is explained below as an example.

In one approach, the terminal device may derive the uplink beam quality based on the downlink beam quality, as described above.

The terminal equipment can perform downlink beam measurement maintenance. Before the MPE problem occurs or in the last measurement period, the terminal device may use channel reciprocity to know the corresponding uplink beam quality before the MPE problem occurs, based on the CSI-RS or each available downlink beam quality. The terminal device may need to power back off after the MPE problem occurs. Therefore, the terminal device may obtain the beam quality after fallback according to the uplink beam quality obtained before and in combination with the current fallback power.

In another mode, the terminal device may perform uplink beam management, so as to obtain the uplink beam quality.

The terminal device may perform uplink Beam management, that is, uplink Beam measurement maintenance, through an srs (srs for Beam management) for Beam management. Before the MPE problem occurs or in the last measurement period, the network device may notify the terminal device of the corresponding uplink beam quality through downlink signaling. The terminal device may need to power back off after the MPE problem occurs. Therefore, the terminal device may obtain each beam quality after fallback according to the uplink beam quality obtained before and in combination with the current fallback power.

It should be understood that, after any of the above manners, when the terminal device determines the beam quality, the backoff power is considered, for example, the terminal device obtains each beam quality after backoff according to the downlink beam quality obtained before and in combination with the current backoff power; for another example, the terminal device obtains the quality of each beam after backoff according to the uplink beam quality obtained before and in combination with the current backoff power.

It should be further understood that the above two manners are only exemplary, and any manner that can enable the terminal device to know or derive the uplink beam quality is applicable to the embodiments of the present application.

Based on the above form 2, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the terminal device may default to use a panel with quality greater than a certain threshold to communicate with the network device, so that not only the beams of the terminal device and the network device may be aligned, but also the signaling overhead may be reduced. In addition, by using panel communication with quality greater than a certain threshold, communication performance can be improved.

Format 3, the default panel includes a plurality of different panels from the M panels.

Optionally, the terminal device communicates using the best beam on each panel.

That is, the terminal device may transmit data using T different ones of the activated panels by default, and accordingly, the network device receives data using the corresponding panels. Wherein T may be an integer greater than 1. T may be pre-agreed, or protocol-specified, or pre-configured by the network device.

For example, the T different panels may be selected from large to small or small to large in order according to the ID. For another example, the T different panels may select the T panels with the highest frequency of use according to the historical communication situation. For another example, the T different panels may be the T panels with the highest quality when used according to the historical communication situation. For another example, the T different panels may select the T panels with the highest frequency of use according to the historical communication situation. As another example, the T different panels can be any of the T different panels. As another example, the T different panels can be all panels that have been activated. As another example, the T different panels can be those that have not experienced MPE problems among the M panels that have been activated.

It is assumed that the panel that the terminal device has activated includes panel #1, panel #2, panel #3, and panel #4, the panel that the terminal device currently communicates with (or the panel that the terminal device will use, such as the panel that the network device schedules data to be transmitted for the terminal device) is panel #1, and the default panel includes M panels.

When the radiation intensity of the terminal equipment exceeds the regulation limit or is about to exceed the regulation limit, the terminal equipment can take some measures to prevent the radiation intensity of the terminal equipment from exceeding the regulation limit, for example, the terminal equipment can perform power back-off on currently used panel # 1.

In a possible case, the terminal device reports the radiation intensity information to the network device. The network device determines that the radiation intensity of the terminal device exceeds or is about to exceed the regulation limit according to the information of the radiation intensity.

As an example, a pre-agreement or protocol provides that when the radiation intensity of the terminal device exceeds or is about to exceed a regulatory limit, 4 panels are used to transmit data. Then, when the network device determines that the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the network device configures the terminal device to transmit data in a repetition (repetition) manner. And the network device may perform ACK acknowledgement on the information of the radiation intensity reported by the terminal device, for example, confirm that the information of the radiation intensity is successfully received by using an NDI flipping method in DCI. After receiving the ACK message, the terminal device transmits data using 4 panels, for example, panel #1, panel #2, panel #3, and panel #4, according to the scheduling of the network device.

As yet another example, when the network device determines that the radiation intensity of the terminal device exceeds or is about to exceed a regulatory limit, the network device configures the terminal device to transmit data using 4 different panels. And the network equipment sends a response message to the terminal equipment, wherein the response message is used for informing the terminal equipment of using different 4 panels to send data. For example, this may be achieved by a 1-bit field. If the bit field takes the value of '1', the terminal equipment is indicated to use 4 different panels to send data; the value of the bit field is "0", which indicates that the terminal device continues to use the current panel to transmit data.

Alternatively, when configuring each panel transmission, the best quality beam pair on the respective panel can be used.

A specific example is shown in fig. 6. The terminal equipment can trigger MPE problem reporting. After knowing that the MPE problem occurs to the terminal equipment, the network equipment adopts a repetition mode to schedule the terminal equipment to send data, and uses different panels to send the data. And the terminal equipment sends data through different panels according to the scheduling of the network equipment.

Based on the above form 3, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the terminal device can communicate with the network device using T different panels by default. Therefore, the beam alignment of the terminal equipment and the network equipment can be realized, and the signaling overhead can be reduced. Further, by using a plurality of panel communications, the communication reliability can also be improved.

Format 4, the default panel includes panels of the M panels other than the first panel.

In this embodiment, the first panel may represent a panel currently communicating with the terminal device; or the first panel may represent a panel to be used by the terminal device, such as a panel used by the network device to schedule data for the terminal device to be transmitted. The first beam may comprise one or more beams, i.e. the terminal device may use one or more beams for communication with the network device or to be communicated with in the present plan. The first panel may include one or more panels, i.e., the terminal device may use one or more panels to communicate with the network device or to communicate with the plan. For convenience of description, the first beam and the first panel are used hereinafter. It should be understood that, taking the first panel as an example, in the case that the first panel includes a plurality of panels, when the radiation intensity occurs or will occur, the power of part of the panels in the first panel may be backed, and the power of all the panels in the first panel may be backed, which is not limited. Optionally, the information of radiation intensity may comprise information relating to the radiation intensity of the first beam and/or the first panel.

That is, in the scheme of form 4, the terminal device may transmit data using a panel other than the first panel among the M panels by default, and accordingly, the network device receives data using the corresponding panel.

It is assumed that the activated panel of the terminal device includes panel #1, panel #2, panel #3, and panel #4, and the first panel is panel # 1.

When the radiation intensity of the terminal equipment exceeds the regulation limit or is about to exceed the regulation limit, the terminal equipment can take some measures to prevent the radiation intensity of the terminal equipment from exceeding the regulation limit, for example, the terminal equipment can perform power back-off on currently used panel # 1. Further, the terminal device can transmit data using panel #2, panel #3, and panel # 4.

As an example, a pre-agreement or protocol provides that when the radiation intensity of the terminal device exceeds or is about to exceed a regulatory limit, data is transmitted using a panel other than the first panel (i.e., panel # 1). Then, when the network device determines that the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limit, the network device configures the terminal device to transmit data using the panel of the activated M panels other than the first panel. And the network device may perform ACK acknowledgement on the information of the radiation intensity reported by the terminal device, for example, confirm that the information of the radiation intensity is successfully received by using an NDI flipping method in DCI. After receiving the ACK message, the terminal device transmits data using a panel other than the first panel (i.e., panel #1), such as panel #2, panel #3, and panel # 4.

As yet another example, when the network device determines that the radiation intensity of the terminal device exceeds or is about to exceed a regulatory limit, the network device configures the terminal device to transmit data using a panel other than the first panel (i.e., panel # 1). The network equipment sends a response message to the terminal equipment, and the response message is used for informing the terminal equipment to send data by using a panel except the first panel. For example, this may be achieved by a 1-bit field. If the bit field takes a value of "1", it indicates that the terminal device uses a panel other than the first panel to transmit data, e.g., uses panel #2, panel #3, and panel #4 to transmit data; the value of the bit field is "0", which indicates that the terminal device continues to use the current panel to transmit data.

A specific example is shown in fig. 7. The terminal equipment can trigger MPE problem reporting. After knowing that the MPE problem occurs to the terminal equipment, the network equipment adopts a repetition mode to schedule the terminal equipment to send data, and uses different panels except the first panel to send the data. The terminal device transmits data through a different panel other than the first panel according to the scheduling of the network device.

Based on the above form 4, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the terminal device may transmit data to communicate with the network device using a panel other than the first panel by default, so that not only the occurrence of the radiation intensity can be avoided, but also the beam alignment of the terminal device and the network device can be made, and the signaling overhead can be reduced.

Format 5, the default panel is the panel after power-back.

That is, the terminal device may transmit data using a power-backed panel by default, and accordingly, the network device receives data using the corresponding panel.

It is assumed that the activated panel of the terminal device includes panel #1, panel #2, panel #3, and panel #4, and the first panel is panel # 1. When the radiation intensity of the terminal equipment exceeds the regulation limit or is about to exceed the regulation limit, the terminal equipment can take some measures to prevent the radiation intensity of the terminal equipment from exceeding the regulation limit, for example, the terminal equipment can perform power back-off on currently used panel # 1. In addition, the terminal device may perform beam measurements.

One possible scenario is that if the terminal device can communicate using the power backed panel, the terminal device can continue to transmit data using the power backed panel # 1. In this case, the terminal device may not report the information of the radiation intensity, that is, the terminal device does not report the information of the radiation intensity, and transmit data using the panel #1 with the power returned.

It is assumed that the panel activated by the terminal device includes panel #1, panel #2, panel #3, and panel #4, and the first panel includes panel #1, panel #2, and panel # 3. When the radiation intensity of the terminal equipment exceeds the regulation limit or is about to exceed the regulation limit, the terminal equipment can take some measures to prevent the radiation intensity of the terminal equipment from exceeding the regulation limit, for example, the terminal equipment can perform power back-off on the panel #1 and the panel # 2. In addition, the terminal device may perform beam measurements.

One possible case is that if the terminal device can communicate using the power-backed panel #1, panel #2, the terminal device can continue to transmit data using the power-backed panel #1, panel # 2. In this case, the terminal device may not report the information of the radiation intensity, that is, the terminal device does not report the information of the radiation intensity, and transmit data using the power-backed panel #1 and panel # 2.

Based on the above form 5, when the terminal device determines that the radiation intensity exceeds the regulatory limit or is about to exceed the regulatory limit, it is possible to avoid the radiation intensity of the terminal device from exceeding the regulatory limit by taking some measures. In addition, the terminal equipment can also continue communication by using a power-backed panel, so that the signaling overhead can be reduced, the time delay caused by panel switching can be reduced, and the communication performance can be improved.

Form 6, the default panel is a panel without power back-off.

That is, the terminal device may transmit data using a panel without power backoff by default, and accordingly, the network device receives data using the corresponding panel.

One possible scenario is that if the terminal device can communicate using the pan #3 without power backoff, the terminal device can continue to transmit data using the pan #3 without power backoff. In this case, the terminal device may not report the information of the radiation intensity, that is, the terminal device does not report the information of the radiation intensity, and transmit data using the panel #3 without power backoff.

Based on the above form 6, when the terminal device determines that the radiation intensity exceeds the regulatory limit or is about to exceed the regulatory limit, it is possible to avoid the radiation intensity of the terminal device from exceeding the regulatory limit by taking some measures. In addition, the terminal equipment can also continue communication by using a panel without power backspace, thereby not only reducing signaling overhead, but also reducing time delay caused by panel switching and improving communication performance.

In form 7, the default panel includes the panel that the terminal device requests to use.

That is, the terminal device may transmit data using a panel recommended by the terminal device by default, and accordingly, the network device receives data using the corresponding panel.

When the radiation intensity of the terminal equipment exceeds the regulation limit or is about to exceed the regulation limit, the terminal equipment reports the information of the radiation intensity to the network equipment, and the information of the radiation intensity comprises a panel recommended by the terminal equipment for uplink transmission. The network device may send a response message to the terminal device acknowledging, by 1 or more bits: whether the terminal equipment sends data according to the recommended panel or not.

Taking 1 bit as an example, the network device sends a response message to the terminal device, for example, the response message may be carried in 1 bit in the control information. The control information includes a plurality of bit fields, and a 1-bit field may be added to the control information to indicate whether the terminal device transmits data according to the recommended panel. For example, the network device corresponding to 0 confirms that the data can be sent according to the recommended panel by the terminal device corresponding to 0, and the network device corresponding to 1 confirms that the data cannot be sent according to the recommended panel by the terminal device corresponding to 1.

Based on the above form 7, when the terminal device determines that the radiation intensity exceeds the regulatory limit or is about to exceed the regulatory limit, it can recommend panel for use in transmitting data to the network device. Therefore, the signaling overhead can be reduced, and the communication performance can be improved.

It should be understood that the above is exemplary of several forms of default panel and is not intended to be limiting. For example, it is also possible to communicate by default using a panel with a person, so that not only the radiation intensity towards the person can be reduced, but also normal communication can be guaranteed. As another example, a best quality panel other than the first panel may also be used by default. As another example, a first panel other than the first panel may also be used by default (e.g., by ID order or by mass). As another example, a panel that does not suffer from MPE problems is used by default.

It should also be understood that the above is mainly exemplified by a default panel, and the above various forms are also applicable to the scheme of the panel indicated by the network device. For example, after the terminal device reports the information of the radiation intensity to the network device, the network device may also display, through 1 bit or multiple bits in the control information, a beam and/or a panel used by the terminal device, where the panel may be any of the above-described forms of panels.

It should be further understood that, in the above scheme 1, the example of reporting the information of the radiation intensity by the terminal device is taken as an example, and this is not limited thereto. For example, the network device may obtain the information about the radiation intensity of the terminal device by other means, such as determining whether the radiation intensity exceeds the regulations or is about to exceed the regulations according to certain conditions, such as determining whether the radiation intensity of the terminal device exceeds the regulations or is about to exceed the regulations according to the communication status of the terminal device. When the network equipment predicts that the radiation intensity of the terminal equipment exceeds the regulation or is about to exceed the regulation, the network equipment can send indication information to the terminal equipment. The terminal device may communicate with the network device using the default beam and/or the default panel after receiving the indication from the network device, or the terminal device may communicate with the network device using the indicated beam and/or the indicated panel.

It should also be understood that when the terminal device sends data to the network device using the default panel, the data may be sent repeatedly. For example, when the default panel includes a plurality of different panels, the terminal device may repeatedly transmit data or transmit repeated data using the plurality of different panels, or the terminal device may repeatedly transmit data or transmit repeated data using the same panel. For another example, when the default panel includes one panel, the terminal device may repeatedly transmit data using the one panel or transmit repeated data. Here, the data is repeatedly transmitted or the data is transmitted repeatedly, that is, the same data is transmitted using different panels. For example, a different Redundancy Version (RV) and/or a different modulation and coding scheme may be used each time data is transmitted.

It should also be understood that several schemes suitable for use with the embodiments of the present application have been described above in connection with the default panel format, and that each scheme may be used alone or in combination.

The form 1 and the form 5 are exemplified by being used in combination. For example, a pre-agreement or a protocol provides that when the radiation intensity of the terminal device exceeds a regulatory limit or is about to exceed the regulatory limit, the default panel may be a panel with the best panel quality among the M panels, or the default panel may also be a panel with power returned, and specifically, may be selected according to an actual communication situation (e.g., according to the size of data volume to be transmitted, channel quality, etc.). In a possible implementation manner, the network device may send a response message to the terminal device, and confirm, through 1 or more bits: the default panel is the panel with the best panel quality among the M panels, or the panel after power return. Taking 1 bit as an example, the network device sends a response message to the terminal device, for example, the response message may be carried in 1 bit in the control information. The control information comprises a plurality of bit fields, and a 1-bit field can be added in the control information to indicate whether the default panel is the panel with the best panel quality among the M panels or the panel with the power fallback. For example, 0 corresponds to the default panel and is the panel with the best panel quality among the M panels, that is, 0 corresponds to the terminal device and uses the panel with the best panel quality among the M panels to transmit data, and 1 corresponds to the default panel and is the panel with the power returned, that is, 1 corresponds to the terminal device and uses the panel with the power returned to transmit data.

It should also be understood that the contents of scheme 1 have been described above primarily in terms of panel, and that the schemes described above apply to beams. I.e., the panels above may all be replaced with beams. If the default beam is the beam with the optimal beam quality in the N beams; as another example, the default beam includes a beam of the N beams having a beam quality greater than a threshold; as another example, the default beam includes a plurality of different beams of the N beams; as another example, the default beam includes a beam of the N beams other than the first beam; as another example, the default beam includes a power-backed beam; as another example, the default beam includes a beam without power backoff; as another example, the default beam includes a beam requested to be used by the terminal device, and so on.

Based on the above scheme 1, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, signaling overhead, transmission delay, reliability and complexity compromise are considered comprehensively, the terminal device reports the radiation intensity information to the network device, and then the terminal device can use a default beam and/or a default panel to communicate with the network device, or the terminal device can use an indicated beam and/or an indicated panel to communicate with the network device. Therefore, the network equipment can not only carry out reasonable configuration for the terminal equipment, but also inform the terminal equipment by using smaller signaling. Therefore, the beams of the terminal device and the network device can be aligned, and the signaling overhead can be reduced.

The contents of scheme 1 are described in detail above, and the contents of scheme 2 are described below.

The description will be made by taking a panel as an example.

It is possible that the terminal device communicates with the network device using a panel without power back-off when the radiation intensity of the terminal device exceeds or is about to exceed regulatory limits.

It is assumed that the activated panels of the terminal device include panel #1, panel #2, panel #3, and panel #4, and the first panel includes panel #1 and panel # 2. When the terminal device uses the panel #1 to cause the radiation intensity to exceed the regulatory limit or to exceed the regulatory limit, the terminal device may take some measures to avoid the radiation intensity of the terminal device from exceeding the regulatory limit, for example, the terminal device may perform power backoff on the panel # 1. In addition, the terminal device may not report the information of the radiation intensity, and continue to use the panel #2 without power back-off to communicate with the network device.

It is further possible that the terminal device communicates with the network device using a power-backed panel when the radiation intensity of the terminal device exceeds or is about to exceed regulatory limits.

In one approach, when the radiation intensity of the terminal device exceeds or is about to exceed regulatory limits, the terminal device communicates with the network device directly using the panel after power return.

In yet another approach, when the radiation intensity of the terminal device exceeds or is about to exceed regulatory limits, the terminal device communicates with the network device using a power-backed panel if certain criteria are met.

The criterion may be, for example, predefined, such as specified by a protocol, or may be indicated by the network device in advance, or may be predefined by the terminal device and the network device.

The criteria may be, for example: the quality of the panel after power return is optimal; or the quality of the panel after the power return meets a certain threshold; or the power back-off value meets a certain threshold; alternatively, the communication environment satisfies a certain condition. The following are described separately.

One possible criterion is: the panel quality after power return is optimal.

That is, when the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limits, the terminal device communicates with the network device using the power-backed panel if the quality of the power-backed panel is optimal.

It is assumed that the panel activated by the terminal device includes panel #1, panel #2, panel #3, and panel # 4.

Example 1, the first panel was panel # 1. When the radiation intensity of the terminal equipment exceeds the regulation limit or is about to exceed the regulation limit, the terminal equipment can take some measures to prevent the radiation intensity of the terminal equipment from exceeding the regulation limit, for example, the terminal equipment can perform power back-off on currently used panel # 1. In addition, the terminal device may perform beam measurement, and if the quality of the panel #1 is the best quality among the panels activated by the terminal device, the terminal device may not report the information of the radiation intensity and continue to use the panel #1 with the power backed off to communicate with the network device.

Example 2, the first panel includes panel #1 and panel # 2. When the terminal device uses the panel #1 to cause the radiation intensity to exceed the regulatory limit or to exceed the regulatory limit, the terminal device may take some measures to avoid the radiation intensity of the terminal device from exceeding the regulatory limit, for example, the terminal device may perform power backoff on the panel # 1. In addition, the terminal device may perform beam measurement, and if the quality of the panel #1 is the best quality among the panels activated by the terminal device, the terminal device may not report the information of the radiation intensity and continue to use the panel #1 with the power backed off to communicate with the network device.

Yet another possible criterion, the panel quality after power backoff meets a certain threshold.

That is, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, if the quality of the power-backed panel is greater than the threshold #2, the terminal device may not report the information of the radiation intensity and continue to use the power-backed panel to communicate with the network device.

The threshold #2 may be used for the terminal device to determine whether the power-backed panel can be used to transmit data. If the quality of the power-backed panel is greater than the threshold #2, the power-backed panel can be used for sending data; and if the quality of the power-backed panel is less than the threshold #2, not using the power-backed panel to transmit data. The case of equality is not limited. For example, when the quality of the power-backed panel is equal to the threshold #2, the power-backed panel may be used to transmit data, or the power-backed panel may not be used to transmit data.

The threshold #2 may be a numerical value, or may be a condition or a criterion, and is not limited. For example, threshold #2 may be a predefined value, such as a protocol predefined value, or a network device configuration notification value; alternatively, the value may be determined from the historical communication situation, and is not limited thereto.

It should be understood that, considering the radiation intensity, the terminal device may power back the currently used panel, that is, when the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limit, if the quality of the power-backed panel is greater than the threshold #2, the terminal device may not report the information of the radiation intensity and use the power-backed panel to transmit data.

Yet another possible criterion is that the power backoff value meets a certain threshold.

That is, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, if the power backoff value is less than the threshold #3, the terminal device may not report the information of the radiation intensity and continue to use the power backed-back panel to communicate with the network device.

The threshold #3 may be used for the terminal device to determine whether the terminal device can continue to use the power-backed panel to transmit data. If the power backoff value is less than the threshold #3, the panel after the power backoff can be used to transmit data; and if the power back-off value is larger than the threshold #3, not using the panel with the power back-off to transmit data. The case of equality is not limited. For example, when the power backoff value is equal to the threshold #3, the power backed-off panel may be used to transmit data, or the power backed-off panel may not be used to transmit data.

The threshold #3 may be a numerical value, a condition or a criterion, and is not limited. For example, threshold #3 may be a predefined value, such as a protocol predefined value, or a network device configuration notification value; alternatively, the value may be determined from the historical communication situation, and is not limited thereto.

It should be understood that, considering the radiation intensity, the terminal device may power back the currently used panel, that is, when the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limit, if the power back value is less than threshold #3, the terminal device may not report the information of the radiation intensity and use the power backed panel to transmit data.

Yet another possible criterion is that the communication environment satisfies a certain condition.

That is, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, if the communication environment meets a certain condition, the terminal device may not report the information of the radiation intensity and continue to use the panel with the power returned to communicate with the network device.

For example, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, if the channel capacity is greater than the threshold #4, the terminal device may not report the information of the radiation intensity and continue to use the power-backed panel to communicate with the network device.

The threshold #4 may be used for the terminal device to determine whether the terminal device can continue to use the power-backed panel to transmit data. If the channel capacity is larger than the threshold #4, continuing to use the panel with the power returned to transmit data; if the channel capacity is less than threshold #4, then the power-backed panel is not used to transmit data. The case of equality is not limited.

The threshold #4 may be a numerical value, a condition or a criterion, and is not limited. For example, threshold #4 may be a predefined value, such as a protocol predefined value, or a network device configuration notification value; alternatively, the value may be determined from the historical communication situation, and is not limited thereto.

It should be understood that, considering the radiation intensity, the terminal device may power back the currently used panel, that is, when the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limit, if the channel capacity is greater than the threshold #4, the terminal device may not report the information of the radiation intensity and use the power-backed panel to transmit data.

It should also be understood that the above lists several possible forms of criteria, which are not limiting. For example, the above criteria may be used in combination, such as different criteria used in different scenarios, as long as the terminal device and the network device are well defined.

It is further possible that the terminal device communicates with the network device using the power backed panel and the non-power backed panel when the radiation intensity of the terminal device exceeds or is about to exceed regulatory limits.

It is assumed that the activated panels of the terminal device include panel #1, panel #2, panel #3, and panel #4, and the first panel includes panel #1 and panel # 2. When the terminal device uses the panel #1 to cause the radiation intensity to exceed the regulatory limit or to exceed the regulatory limit, the terminal device may take some measures to avoid the radiation intensity of the terminal device from exceeding the regulatory limit, for example, the terminal device may perform power backoff on the panel # 1. In addition, the terminal device may not report the information of the radiation intensity, and continue to use the power backed panel #1 and the power backed panel #2 to communicate with the network device.

It is to be understood that the above lists several possibilities, which are not limiting. For example, the terminal device may also send data to the network device through any of the above cases, and carry information about the radiation intensity therein, and after the network device receives the information, the network device may reconfigure a used beam and/or panel for the terminal device, or may also configure the terminal device to repeatedly send data, and so on. For another example, the terminal device may determine through any of the above criteria when passing through the first case, i.e., when using a beam and/or a panel without power backoff.

Based on the above scheme 2, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the terminal device may continue to use the currently used beam and/or panel to communicate with the network device according to the quality of the currently used beam and/or panel, or channel capacity, etc., by comprehensively considering the signaling overhead, transmission delay, reliability and complexity tradeoffs, i.e., using the power backed-off beam and/or panel to communicate with the network device. Therefore, not only can the beams of the terminal device and the network device be aligned, but also signaling overhead can be greatly reduced, for example, no signaling message (namely, the radiation intensity does not need to be reported, and the beam and/or the panel used for uplink transmission does not need to be indicated) can be realized.

It should be understood that the above is mainly exemplified by a panel, and the above-described schemes are applicable to beams. I.e., the panels above may all be replaced with beams. The terminal device communicates with the network device using a beam without power backoff, such as when the radiation intensity of the terminal device exceeds or is about to exceed regulatory limits; for another example, when the radiation intensity of the terminal device exceeds or is about to exceed the regulatory limit, the terminal device directly uses the power-backed beam to communicate with the network device; for another example, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, if the beam quality after power backoff is optimal, the terminal device uses the beam after power backoff to communicate with the network device; for another example, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, if the beam quality after power backoff meets a certain threshold or the power backoff value meets a certain threshold or the communication environment meets the condition, the terminal device uses the beam after power backoff to communicate with the network device; as another example, when the radiation intensity of the terminal device exceeds or is about to exceed regulatory limits, the terminal device communicates with the network device using the power-backed beam and the beam without power backoff.

The contents of scheme 1 and scheme 2 are introduced above, respectively. It should be understood that the above-described schemes are merely illustrative and not restrictive. For example, when the terminal device does not report the information of the radiation intensity, the terminal device may use the beam and/or the panel currently used for communication to communicate with the network device, or may also use the beam and/or the panel indicated by the network device to communicate with the network device.

Alternatively, scheme 1 and scheme 2 above may or may not be related.

In one case, case 1 and case 2 may be related.

In a possible association manner, before reporting the information of the radiation intensity to the network device, the terminal device may first determine whether the information of the radiation intensity needs to be reported. The scheme of scheme 1 can be used under the condition that the information of the radiation intensity needs to be reported; the scheme of scheme 2 may be used without reporting information on the radiation intensity.

And a possible judgment mode is to determine whether the information of the radiation intensity needs to be reported or not according to the quality of the beam and/or the panel after the power is returned.

For example, if the quality of the beam and/or the panel after the power backoff meets a certain condition, the terminal device determines not to report the information of the radiation intensity, otherwise, reports the information. The condition may be, for example, predefined, such as specified by a protocol, or may be indicated by the network device in advance, or may be predefined by the terminal device and the network device. The conditions may be, for example: the beam and/or panel quality after the power is backed off is optimal; alternatively, the power-backed beam and/or panel quality meets a certain threshold.

For example, if the beam and/or the panel quality after the power backoff is optimal, the terminal device determines not to report the information of the radiation intensity, otherwise, reports the information.

For another example, if the beam and/or the panel quality after the power backoff is greater than the threshold #5, the terminal device determines not to report the radiation intensity information, otherwise, reports the radiation intensity information. The threshold #5 may be used for the terminal device to determine whether the radiation intensity information needs to be reported. If the beam and/or the panel quality after the power return is larger than the threshold #5, the terminal equipment does not need to report the information of the radiation intensity; if the beam and/or panel quality after the power backoff is smaller than the threshold #5, the terminal device needs to report the information of the radiation intensity. The case of equality is not limited.

In another possible judgment mode, whether the information of the radiation intensity needs to be reported is determined according to the power back-off value.

For example, if the power back-off value is smaller than the threshold #6, the terminal device determines not to report the information of the radiation intensity, otherwise, reports. The threshold #6 may be used for the terminal device to determine whether the radiation intensity information needs to be reported. If the power back-off value is smaller than the threshold #6, the terminal equipment does not need to report the information of the radiation intensity; if the power back-off value is greater than the threshold #6, the terminal device needs to report the radiation intensity information. The case of equality is not limited.

Another possible judgment method determines whether the information of the radiation intensity needs to be reported according to the communication environment.

For example, if the channel capacity is greater than threshold #7, the terminal device determines not to report the radiation intensity information, otherwise, reports. The threshold #7 may be used for the terminal device to determine whether the radiation intensity information needs to be reported. If the channel capacity is larger than the threshold #7, the terminal equipment does not need to report the information of the radiation intensity; if the channel capacity is smaller than the threshold #7, the terminal device needs to report the radiation intensity information. The case of equality is not limited.

It should be understood that the above-mentioned association is only illustrative and not restrictive. For example, the terminal device may also transmit data using scheme 2 first, and relevant information about the radiation intensity is carried in the data. After the network device receives the data, the terminal device can transmit the data by using the scheme 1 again; or the network device may reconfigure the used beams and/or panels, etc. for the terminal device. Illustratively, scheme 1 or scheme 2 may be selected according to the actual communication situation.

In yet another case, case 1 and case 2 may not be associated.

For example, the terminal device may directly report the information of the radiation intensity. Further, the terminal device may communicate with the network device using a default beam and/or panel, or the terminal device may communicate with the network device using an indicated beam and/or panel.

The above mainly introduces scheme 1 and scheme 2, and the following introduces the information of the radiation intensity and the way of reporting the information of the radiation intensity by the terminal device.

And the terminal equipment reports the triggering condition of the information of the radiation intensity.

In the embodiment of the application, the terminal device notifies the network device of information related to the current or future radiation intensity, such as notifying the network device that the radiation intensity exceeds or is about to exceed a regulation limit, and further such as notifying the network device of information related to the radiation intensity. Therefore, the network device can be conveniently configured and scheduled reasonably based on the relevant information of the radiation intensity, and can also transmit signals or channels (i.e. transmit and receive signals or channels).

For example, the terminal device may periodically report the information of the radiation intensity to the network device, e.g., the terminal device may periodically report the information of the radiation intensity to the network device so as to inform the network device of the information about the radiation intensity. Or, as another example, when the terminal device determines that the radiation intensity exceeds the regulatory constraint, the terminal device reports the information of the radiation intensity to the network device so as to notify the network device that the radiation intensity exceeds the regulatory constraint. Or, as another example, when the terminal device determines that the radiation intensity is about to exceed the regulatory constraint, the terminal device reports the information of the radiation intensity to the network device so as to inform the network device that the radiation intensity is about to exceed the regulatory constraint.

The information of the radiation intensity may for example comprise one or more of: PD, MPE percentage, transmission power, uplink transmission duty cycle flag, uplink transmission duty cycle value, candidate transmission beams or panels, warning information, power backoff flag, power backoff value, power headroom or energy headroom, terminal device power backed-off beams and/or panel quality, information of recommended beams, information of recommended panels, flag indicating that uplink transmission duty cycle needs to be reduced, duty cycle value of uplink transmission needs to be reduced, etc. The terminal device can help the network device to reasonably schedule and configure for subsequent communication by telling the network device about the information.

Where the MPE percentage is the percentage compared to the MPE limit. The percentage MPE means X% MPE is reached, 100% MPE means 1 (mW/cm)²). FCC MPE can be limited to 1 (mW/cm)²)。

Wherein the PD may be in units of milliwatts per square centimeter (mW/cm)²). The transmission power may comprise, for example, EIRP, which may be in units of mW or dBm.

The alarm information may be, for example, MPE risk or MPE problem occurrence or radiation intensity exceeding a regulatory constraint, or alternatively, the alarm information may be that MPE risk or MPE problem occurrence or radiation intensity exceeding a regulatory constraint is about to occur.

It should be understood that the above listed information of radiation intensity is only an exemplary illustration, and is not limited thereto, and as long as the information is related to radiation of the terminal device, the information falls into the protection scope of the embodiments of the present application.

Alternatively, the terminal device may perform monitoring management in units of a panel or a beam, for example, the terminal device maintains a set of management information for each activated beam or panel, respectively, that is, a monitoring management mechanism based on the beam or panel. Alternatively, the terminal device may perform monitoring management in units of all active panels or beams, for example, the terminal device maintains a set of management information for all active panels or all active panels, i.e. a monitoring management mechanism based on the beams or the panels. Or reporting may be performed in units of terminal devices, which is not limited herein.

Optionally, the terminal device may report the information of the radiation intensity in any one of the following manners.

In implementation mode 1, the terminal device notifies the network device of the radiation intensity information through Uplink Control Information (UCI). For example, the terminal device may inform the network device of the occurrence of MPE problem through UCI specific information. Correspondingly, the network device can also determine that the MPE problem occurs in the terminal device based on the UCI.

In implementation mode 2, the terminal device may notify the network device of the information of the radiation intensity through the identification bit. Illustratively, the terminal device may notify the network device of the radiation intensity information through a Power Headroom Report (PHR).

For example, the terminal device may notify the information of the radiation intensity of the network device through a 'P' bit carried by the PHR; for another example, the terminal device may notify the network device by separately designing the physical layer identification bit. The terminal device may report on the basis of the beam or the panel, for example, report that an MPE problem occurs in a certain beam or a certain panel, and other related information (for example, a power back-off value of the beam or the panel, etc.); or it may not report on a beam or panel basis, such as reporting MPE problems occurring or about to occur at the terminal device.

For another example, the terminal device only informs the network device through the P-MPR carried in the PHR, and the terminal device has an MPE problem. Correspondingly, the network device can also determine that the MPE problem occurs in the terminal device based on the PHR.

In implementation manner 3, the terminal device may notify the network device of the radiation intensity information through the uplink signal. The uplink signal may be: SRS, demodulation reference signal (DMRS), uplink Phase Tracking Reference Signal (PTRS), preamble (preamble), and the like. Correspondingly, the network equipment can also determine that the MPE problem occurs in the terminal equipment based on the uplink signal.

It should be understood that the above is only exemplary, and any manner of reporting the radiation intensity is applicable to the embodiments of the present application. As an example, the terminal device may use few bits (e.g., 1 bit) to report whether an MPE problem occurs. For another example, the terminal device may report whether an MPE problem occurs through the power back-off value, for example, the MPE reports a specific value or a plurality of specific values of the power back-off value, which indicates whether an MPE problem occurs. For example multiplexing the current version, a certain value of the MPE power back-off report value, such as 0000 or 1111, indicates that MPE is problematic. For another example, each terminal device reports without distinguishing between panel or beam, for example, using a table of current possible MPE report values, see table 3.

It should be understood that, in some embodiments, when the radiation intensity exceeds or is about to exceed the regulatory constraint, the power back-off is taken as an example for description, but this does not limit the application, and any treatment manner capable of reducing the radiation intensity is applicable to the embodiments of the application.

It should also be understood that in some of the above embodiments, MPE constraints are taken as an example for illustration, but this is not a limitation of the present application, and any constraint that can characterize radiation intensity is applicable to the embodiments of the present application, for example, SAR constraints.

It should also be understood that, in some embodiments described above, the terminal device uses a default beam and/or a default panel to transmit data (such as PUSCH) for example, but this does not limit the present application. The terminal device may use the default beam and/or default panel to send data or signals or signaling, etc. to the network device.

It should also be understood that in the above embodiments, reference is made to the terminal device transmitting a signal or channel (e.g., a data channel, PUSCH) using a default or indicated beam, which may include one or more beams, and/or a panel, which may include one or more panels.

It should also be understood that the above embodiments are mainly exemplified by using beams and/or panels for communication, and are not limited thereto. For example, in a low-frequency radiation constraint scenario, when the antenna is used for communication, the scheme related to the above embodiment may also be used.

Based on the above technical solution, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, the terminal device may continue to use the currently used beam and/or panel to communicate with the network device according to the quality of the currently used beam and/or panel, or the channel capacity, etc., by comprehensively considering the signaling overhead, transmission delay, reliability and complexity trade-offs, for example, using the power backed-off beam and/or panel to communicate with the network device. Therefore, not only can the beams of the terminal device and the network device be aligned, but also signaling overhead can be greatly reduced, for example, no signaling message (namely, the radiation intensity does not need to be reported, and the beam and/or the panel used for uplink transmission does not need to be indicated) can be realized. In addition, the system time delay can be reduced, and the communication performance can be improved.

In addition, based on the above technical solution, when the radiation intensity of the terminal device exceeds the regulatory limit or is about to exceed the regulatory limit, signaling overhead, transmission delay, reliability and complexity compromise are considered comprehensively, the terminal device reports the radiation intensity information to the network device, and communication is performed by using a default beam and/or a default panel. Therefore, the network equipment can not only carry out reasonable configuration for the terminal equipment, but also inform the terminal equipment by using smaller signaling. Therefore, the beams of the terminal device and the network device can be aligned, and the signaling overhead can be reduced. In addition, the system time delay is reduced, and the system performance loss caused by the MPE problem is reduced.

The various embodiments described herein may be implemented as stand-alone solutions or combined in accordance with inherent logic and are intended to fall within the scope of the present application.

It is to be understood that, in the above-described method embodiments, the method and the operation implemented by the terminal device may also be implemented by a component (e.g., a chip or a circuit) available for the terminal device, and the method and the operation implemented by the network device may also be implemented by a component (e.g., a chip or a circuit) available for the network device.

A transceiver unit may also sometimes be referred to as a transceiver, transceiving circuitry, or the like. A receiving unit may also be referred to as a receiver, a receiving circuit, or the like.
