Description

Method, device, chip and storage medium for notifying state of antenna panel

The present application is a divisional application, the original application having application number 201910722074.9, the original application date being 2019, 08 and 6, the entire content of the original application being incorporated by reference in the present application.

Technical Field

The present application relates to the field of communications, and in particular, to a method, an apparatus, a chip, and a storage medium for notifying an antenna panel status.

Background

In a high-frequency communication system, in order to overcome the path loss, both a network device and a terminal generally perform communication using a directional high-gain antenna array (analog beam). Since both the network device and the terminal can generate a plurality of beams, it is necessary to select a beam in a suitable direction for communication.

In high frequency communication systems, a terminal device is usually equipped with a plurality of antenna panels (antenna panels), or antenna arrays (antenna arrays), which can cover a plurality of different directions, and each antenna panel can be responsible for generating one or more beams. Fig. 1 schematically shows a configuration of a terminal device equipped with a plurality of antenna panels, and as shown in fig. 1, a terminal device 100 is equipped with a plurality of antenna panels 101. Each antenna panel 101 of the terminal device 100 may face in one direction.

At present, one implementation is that the terminal device only makes one antenna panel in an activated (activation) state at the same time, and the other antenna panels are in a deactivated (deactivation) state. The antenna panel in the activated state can be used for data transmission, the antenna panel in the deactivated state cannot be used for data transmission, and the data transmission is data transmission or data reception. An antenna panel of the terminal device is switchable between an activated state and a deactivated state.

In the prior art, the network device does not sense the state of the antenna panel of the terminal device, and thus, when the network device performs scheduling, the antenna panel in a deactivated state may be scheduled, which may further cause data transmission failure or data transmission time lengthening.

Fig. 2 shows a schematic architecture diagram of a communication system to which embodiments of the present application are applied. As shown in fig. 2, the communication system may include a network device 201 and one or more terminal devices 202, and the network device 201 and the terminal devices 202 are connected by a wireless connection or a wired connection or other means.

The network device may be a Base Transceiver Station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) network device, or may be an nb (nodeb) in a Wideband Code Division Multiple Access (WCDMA), or may be an eNB or enodeb (enodeb) in a Long Term Evolution (Long Term Evolution, LTE). The Network device may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario. The network device may also be a network device in a future 5G network device or a network device in a future evolved PLMN network. The network device 201 may also be a wearable device or a vehicle mounted device.

The terminal device may be a User Equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a remote terminal, a mobile device, a terminal, a wireless communication device, a terminal agent, or a terminal Equipment, etc. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a terminal device in a future 5G network device or a terminal device in a future evolved PLMN network device, etc.

In the embodiments of the present application, the term "network device" includes, but is not limited to, a node, a station controller, an Access Point (AP), or any other type of interface device capable of operating in a wireless environment.

The antenna panel (antenna panel) in the embodiment of the present application may be referred to as a panel (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 the antenna panel or may transmit signals via a transmit beam on the antenna panel.

Specifically, the network device and the terminal device communicate through an antenna, that is, the terminal device and the network device receive and transmit signals through the antenna. The terminal equipment and the network equipment are provided with antenna units (antenna elements). A plurality of antenna elements may be integrated in a panel, and the panel with integrated antenna elements is called an antenna panel (also denoted by panel). Each antenna panel may generate one or more beams (beams), i.e., each antenna panel may transmit and receive signals in one or more directions.

The antenna panel may also be denoted as an antenna array (antenna array) or an antenna sub-array (antenna subarray). One antenna panel may include one or more antenna arrays (antenna sub-arrays). An antenna panel may be controlled by one or more oscillators (oscillators). One radio frequency circuit may drive one or more antenna elements on the antenna panel. Thus, one antenna panel may be driven by one radio frequency link, or may be driven by multiple radio frequency links. The radio frequency link may also be referred to as a receive path and/or a transmit path, a receiver branch (receiver branch), and so on. Therefore, the antenna panel may also be replaced by a radio frequency link or a plurality of radio frequency links driving one antenna panel or one or more radio frequency links controlled by one crystal oscillator.

An antenna panel may also be a logical concept, an antenna panel may be a logical entity, (i.e. not embodying physical antenna structures), such as a set of antenna ports, or a set of transmit and/or receive beams, or a set of transmit and/or receive directions.

In the embodiment of the present application, the terminal device and the network device may distinguish the antenna panel by the panel identification ID. The identifier of the antenna panel may be a logical identifier, or may be embodied as a reference signal resource set identifier (and/or a synchronization signal block resource set identifier), for example, a Sounding Reference Signal (SRS) resource set ID, a channel state information reference signal (CSI-RS) resource set ID, or the like, or may be a reference signal resource identifier (and/or a synchronization signal block resource identifier), for example, an SRS resource ID, a CSI-RS resource ID, or the like. When the panel is identified as the identifier of the reference signal resource or the reference signal resource set, if the identifier is the uplink reference signal resource (or the uplink reference signal resource set), the identifier corresponds to the uplink transmitting antenna panel or the downlink receiving panel corresponding to the uplink transmitting antenna panel which transmits the uplink reference signal resource (or the uplink reference signal resource set); if the identifier is a downlink reference signal resource and/or a synchronization signal resource, the identifier corresponds to a downlink receiving panel for receiving the downlink resource and/or the synchronization signal resource or an uplink sending panel corresponding to the downlink receiving panel.

The terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In the present application, "at least one" means one or more, "a plurality" means two or more. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

Identification or identification information for identifying an object, which may be: terminal equipment and a user. An identifier may include at least one of a name, a number, an id (identification), as long as the identified object can be distinguished from other objects.

Based on the system architecture shown in fig. 2, fig. 3 exemplarily shows a flowchart of a notification method for an antenna panel status provided in an embodiment of the present application, and as shown in fig. 3, the method includes the following steps:

step 301, a first antenna panel of a terminal device is changed from an activated state to a deactivated state, and a notification message is sent to a network device; the notification message is used for indicating that the first antenna panel is changed from the activated state to the deactivated state.

The terms "first", "second", "third", and "fourth" in the "first antenna panel", "second antenna panel", "third antenna panel", and "fourth antenna panel" in the embodiments of the present application are merely for distinction and do not have a limiting meaning. The first antenna panel is any one of the antenna panels of the terminal device.

The antenna panel of the terminal device in the embodiment of the present application has two states, an activation (activation) state and a deactivation (deactivation) state. The antenna panel is in an activated state, which means that the antenna panel can be used for data transmission, for example, the antenna panel is in an activated state, or the activated state can also be referred to as an ON state, a power-ON state, or the like. The deactivated state refers to that the antenna panel cannot be used for data transmission, for example, the antenna panel is in an inactivated state, and may also refer to that the antenna panel is in a dormant state or an OFF state, which may also be referred to as an OFF state, or a power-down state.

Correspondingly, the network device receives a notification message sent by the terminal device, wherein the notification message is used for indicating that the first antenna panel of the terminal device is changed from the activated state to the deactivated state.

Step 302, the network device determines that the first antenna panel is changed from the activated state to the deactivated state according to the notification message.

Since the antenna panel of the terminal device is invisible to the network device in the existing 3GPP Release 15(R15) protocol, or it can be said that the R15 protocol mainly manages the single-panel terminal device. In the prior art, when a network device schedules a terminal device to perform uplink transmission, it is not concerned which antenna panel the terminal device uses to transmit, nor is it concerned that the antenna panel of the terminal device is in an activated or deactivated state, and in this case, the probability of scheduling the terminal device in the deactivated state is high.

Fig. 4 exemplarily shows a flow chart of another notification method for an antenna panel state provided in the embodiment of the present application. Both

steps

401 and 402 of fig. 4 may occur before step 301 of fig. 3 described above, as shown in fig. 4, including the following steps:

step 401, the terminal device reports the capability parameter of the terminal device, and the network device configures the parameter corresponding to the terminal device.

Step 401 may occur before step 301 of fig. 3 described above.

In a possible embodiment, a connection may be established and interaction may be performed between the network device and the terminal device. For example, the terminal device may report its own capability parameter to the network device, where the capability parameter may include, for example, a capability class (UE Power class) of the terminal device. For example, if the capability level of the terminal device is level 1, the type of the terminal device is a Fixed Wireless Access (FWA) terminal device. For another example, if the capability level of the terminal device is level 2, the type of the terminal device is a Vehicular (Vehicular) terminal device. The capability parameters may also include the terminal device's capability to support an antenna panel, such as whether the terminal device supports a single antenna panel or a multiple antenna panel.

The parameter corresponding to the terminal device configured by the network device may include an output power variation threshold of the terminal device used in the subsequent embodiments.

In step 402, the terminal device communicates with the network device via the first antenna panel.

Specifically, the terminal device may use the first antenna panel for data transmission with the network device, such as transmitting uplink physical channels and signals through the first antenna panel.

In an optional implementation manner, the notification message in step 301 may be a power head room report (PHR). In this case, the operation of step 301 may be replaced with step 403 described below.

Step 403, the first antenna panel of the terminal device changes from the active state to the deactivated state, and sends a first remaining power packet to the network device. The output power in the first residual power message is a first preset value corresponding to the first antenna panel, and/or; and the residual power in the first residual power message is a second preset value corresponding to the first antenna panel.

In the embodiment of the present application, "first" and "second" in "first remaining power message" and "second remaining power message" are merely for distinction and have no limiting meaning.

In the existing R15 protocol, it is specified that in order to better serve the uplink transmission of the terminal device, the terminal device is allowed to report the PHR MAC CE. The reporting condition of the remaining Power message specified in R15, "a Power Head Report (PHR) short be triggered if of the following events ocur:

phr-ProhibitTimer expires or has expired and the path loss has changed more than phr-Tx-PowerFactorChange dB for at least one activated Serving Cell of any MAC entity which is used as a pathloss reference since the last transmission of a PHR in this MAC entity when the MAC entity has UL resources for new transmission”。

the corresponding Chinese of the reporting condition is: "when the timer PHR-ProhibitTimer expires or the path loss change exceeds PHR-Tx-PowerFactorChange dB, the PHR message is triggered. Wherein, the first limiting condition of the path loss change is as follows: at least one activated service cell of any MAC entity transmits the path loss reference of the PHR last time; second limiting condition for path loss change: this MAC entity has available uplink resources. ".

In the embodiment provided in fig. 4 in the present application, a trigger condition is provided for the remaining power packet, that is: "the antenna panel changes from the activated state to the deactivated state, and triggers the residual power message". That is to say, in the embodiment of the present application, synchronization of the antenna panel states of the terminal device may be implemented by using an existing remaining power message in the prior art. On the other hand, the network device may change the state of the first antenna panel from the activated state to the deactivated state according to the remaining power message by using the output power in the first remaining power message as the first preset value corresponding to the first antenna panel and/or by using the remaining power in the first remaining power message as the second preset value corresponding to the first antenna panel.

Further, optionally, the remaining power message may also be triggered when the antenna panel changes from the deactivated state to the activated state, in this case, the following may also be described: and triggering the residual power message when the state of the antenna panel of the terminal equipment is changed.

The terminal device can inform the network device about the output power of the terminal device and the residual power of the terminal device by reporting the residual power message. In this embodiment, the output power of the terminal device may indicate an Uplink transmission capability of the terminal device, and the remaining power may indicate how much remaining power remains after current Uplink transmission is performed (for example, after a Physical Uplink Shared CHannel (PUSCH), a Physical Uplink Control CHannel (PUCCH), or a Sounding Reference Signal (SRS) is sent).

In the embodiment of the present application, the terminal device may have one antenna panel, or may have a plurality of antenna panels as shown in fig. 1, where each antenna panel has two parameters, that is, an output power of the antenna panel and a remaining power of the antenna panel. The output power of the terminal device may be determined from the output power of the antenna panel on the terminal device, and the remaining power of the terminal device may be determined from the remaining power of the antenna panel on the terminal device.

In a possible embodiment, considering that the capabilities of the antenna panels of the terminal device may be different, the output power of the terminal device may be the maximum of the output powers of all the antenna panels in the active state on the terminal device. In a possible embodiment, the remaining power of the terminal device may be reported according to an actual situation, for example, the difference obtained by subtracting the power currently used by the terminal device for data transmission from the output power of the terminal device may be used as the remaining power.

In an alternative approach for implementing step 403, when the absolute value of the variation of the output power of the first antenna panel of the terminal device is greater than or equal to the output power variation threshold: a notification message is sent to the network device. It can also be described as: and if the absolute value of the variation of the output power of the first antenna panel of the terminal equipment is greater than or equal to the threshold of the variation of the output power, triggering the report of the notification message. The threshold of the output power variation may be preset, or may be issued by the network device, or may be negotiated between the base station and the network device through some signaling, for example, the network device may configure the threshold of the output power variation for the terminal device in step 401.

In another alternative scheme for implementing step 403, when the absolute value of the variation of the remaining power of the first antenna panel of the terminal device is greater than or equal to the remaining power variation threshold: a notification message is sent to the network device. It can also be described as: and if the absolute value of the variation of the residual power of the first antenna panel of the terminal equipment is greater than or equal to the threshold of the variation of the output power, triggering the report of the notification message. The remaining power variation threshold may be preset, or may be issued by the network device, or may be negotiated between the base station and the network device through some signaling, for example, the network device may configure the remaining power variation threshold for the terminal device in step 401.

In another alternative scheme for implementing step 403, when the absolute value of the variation of the output power of the terminal device is greater than or equal to the output power variation threshold: a notification message is sent to the network device. It can also be described as: and if the absolute value of the variable quantity of the output power of the terminal equipment is greater than or equal to the variable quantity threshold of the output power, triggering the report of the notification message.

In another alternative scheme for implementing step 403, when the absolute value of the variation of the remaining power of the terminal device is greater than or equal to the remaining power variation threshold: a notification message is sent to the network device. It can also be described as: and if the absolute value of the variable quantity of the residual power of the terminal equipment is greater than or equal to the variable quantity threshold of the output power, triggering the report of the notification message.

In this embodiment, the notification message may be a remaining power message. In an optional implementation manner, when the notification message is a remaining power message, in this embodiment of the present application, the following may also be described as: setting a reporting condition for the remaining power message, where the reporting condition for the remaining power message may be, for example: the absolute value of the variation of the output power of the first antenna panel of the terminal equipment is greater than or equal to the threshold of the variation of the output power; the absolute value of the variation of the remaining power of the first antenna panel of the terminal device may be greater than or equal to the remaining power variation threshold; or the absolute value of the variation of the output power of the terminal equipment is larger than or equal to the threshold of the variation of the output power; or the absolute value of the amount of change in the remaining power of the terminal device may be greater than or equal to the remaining power change amount threshold.

Optionally, when the first antenna panel is in an active state, the active state is changed to a deactivated state, that is, the terminal device changes from performing data transmission through the first antenna panel to stopping performing data transmission using the first antenna panel, both the output power and the remaining power of the first antenna panel return to zero. In this case, the variation of the output power of the first antenna panel is a difference between the output power of the first antenna panel in the activated state and zero, and it can be seen that the variation of the output power of the first antenna panel is large and is larger than a preset threshold of the variation of the output power. In practical applications, since the output power of the first antenna panel in the activated state may be a negative number, the variation of the output power of the first antenna panel may be a negative number, in which case an absolute value of the variation of the output power may be obtained, and then the absolute value of the variation of the output power may be compared with the threshold of the variation of the output power.

Fig. 5 exemplarily shows a structural diagram of a remaining power message, as shown in fig. 5, a field 501 for carrying remaining power of a terminal device, a field 502 for carrying output power of the terminal device, and some reserved bits 503 are included in the remaining power message in the existing protocol.

The remaining power message is a signaling message that occupies 2 bytes (16 bits), and the reserved bit 503 may be set to 0. The field 501 for carrying the remaining power of the terminal device occupies 6 bits and can be represented by PH, and the field 501 for carrying the remaining power of the terminal device can include two parameters, which are respectively written as a type parameter and a cell parameter. The type parameter refers to the type of the remaining power message, three types of remaining power message reporting types are defined in the original protocol, and the embodiment of the present application does not relate to a specific type, that is, any type may be used. The Type parameter can be specifically selected by three values, Type 1, Type 2, and Type 3, respectively. Type 1 specifically refers to the difference between the output power and the power of the uplink data channel transmission in the protocol. Type 2 refers in the protocol to the difference between the output power and the power of the uplink control channel transmission. Type 3 refers in the protocol to the difference between the nominal power and the power of the uplink sounding signal transmission. The cell parameters may be written specifically into Pcell, where Pcell refers to a primary cell, and in the embodiment of the present application, the cell parameters may be other values, and are not necessarily the primary cell.

The output power of the terminal device may also be referred to as a maximum output power, where the english is "nominal power", and in some cases, may also be referred to as a rated maximum power, or may be directly called a rated power, and the english may also be "nominal power". The output power field of the terminal device may occupy one or more bits, e.g., 6 bits, and may be denoted as P _CMAX,f，c . Wherein f refers to a carrier frequency (carrier), and c refers to a serving cell (serving cell). It should be noted that the specific numbers referred to in the embodiments of the present application are merely examples and are not meant to be limiting.

The meaning of the 6 bits of the field 501 for carrying the remaining power of the terminal device shown in fig. 5 can be determined by table 1 and table 2. Table 1 and table 2 each illustrate the meaning of the numbers carried in the field 501 for carrying the remaining power of the terminal device in fig. 5. Taking the values of the first two rows of tables 1 and 2 as an example, as shown in table 1, when the value of the field 501 for carrying the remaining POWER of the terminal device is 0, it indicates that the remaining POWER level of the terminal device is "POWER _ HEADROOM _ 0", and as can be seen from table 2, when the remaining POWER level of the terminal device is "POWER _ HEADROOM _ 0", it indicates that the remaining POWER of the terminal device is less than-32 decibels (dB). For another example: as shown in table 1, when the value of the field 501 for carrying the remaining POWER of the terminal device is 1, it indicates that the remaining POWER level of the terminal device is "POWER _ HEADROOM _ 1", and as can be seen from table 2, when the remaining POWER level of the terminal device is "POWER _ HEADROOM _ 1", it indicates that the remaining POWER of the terminal device is not less than-32 dB and less than-31 dB.

The meaning of the 6 bits of the field 502 shown in fig. 5 for carrying the output power of the terminal device can be determined by table 3 and table 4. Table 3 and table 4 each illustrate the meaning of the numbers carried in the field 502 for carrying the output power of the terminal device in fig. 5. Taking the values in the first two rows of tables 3 and 4 as an example, as shown in table 3, when the value of the field 502 for carrying the output power of the terminal device is 0, it indicates that the output power level of the terminal device is "PCMAX _ C _ 00", and as can be seen from table 4, when the output power level of the terminal device is "PCMAX _ C _ 00", it indicates that the output power of the terminal device is less than-29 decibel milliwatts (dBm). For another example: as shown in table 3, when the value of the field 502 for carrying the output power of the terminal device is 1, it indicates that the output power level of the terminal device is "PCMAX _ C _ 01", and as can be seen from table 4, when the output power level of the terminal device is "PCMAX _ C _ 01", it indicates that the output power of the terminal device is not less than-29 dBm and less than-28 dBm.

Table 4 output power information (Mapping of P) of terminal device in remaining power message _CMAX,f，c )

In step 403, a first preset value corresponding to each antenna panel may be separately set for each antenna panel, and the first preset values corresponding to any two antenna panels may be different or the same. The second preset value corresponding to each antenna panel may also be set separately for each antenna panel, and the second preset values corresponding to any two antenna panels may be different or the same.

In a possible embodiment, the first preset value may be set to 000000 and the second preset value may be set to 000000. It can be seen from table 1 and packet 2 that when the remaining power value 000000 indicates that the remaining power is less than-32 dB, and when the output power value 000000 indicates that the remaining power is less than-29 dBm, these two cases are basically impossible to occur in practical application, so if at least one of the output power and the remaining power in the remaining power message reported by the terminal device is 000000, the network device may determine that the antenna panel currently performing data transmission has been changed from the active state to the inactive state.

In the embodiment of the present application, the first preset value corresponding to each antenna panel may have a plurality of values, and the second preset value corresponding to each antenna panel may also have a plurality of values. In this case, by setting the output power to the first preset value corresponding to the first antenna panel and/or setting the remaining power to the second preset value corresponding to the first antenna panel, it is possible to indicate that the first antenna panel is changed from the activated state to the deactivated state, and also indicate the reason why the first antenna panel is changed from the activated state to the deactivated state this time. For example, the remaining power is 000000, and the output power is 111111. In this example, the values of the remaining power and the output power may also be expressed as: although the terminal device has output power, the remaining power is zero, and the network device may determine that the antenna panel currently performing data transmission is stopped from being used and is in a deactivated state. The values in this example may be due to the occurrence of a Maximum Permissible Emission (MPE) event. The MPE event means that the terminal equipment estimates that the radiation of a wireless signal transmitted by the terminal equipment per se exceeds the maximum allowable exposure amount limited by a regulation on human body through measurement or calculation and the like, and in this case, the terminal equipment may need to actively reduce the self-transmitting power and reduce the transmitting time ratio or switch to another transmitting antenna panel or beam so that the terminal equipment is not aligned with the direction of the human body any more. In this example, when the remaining power value in the first remaining power message sent by the terminal device is 000000, the output power value is 111111, and the network device determines that the first antenna panel is changed from the activated state to the deactivated state, and also determines that the reason why the first antenna panel is changed from the activated state to the deactivated state this time is due to an MPE event.

In step 403, the first remaining power message may further include first indication information, where the first indication information is used to indicate a reason for changing the state of the first antenna panel. In an optional implementation manner, in the example in the last paragraph, the reason for changing the state of the first antenna panel may be indicated by setting the output power to a first preset value corresponding to the first antenna panel and setting the remaining power to a second preset value corresponding to the first antenna panel, where in this case, the first indication information may be the first preset value carried by the output power field and the second preset value carried by the remaining power field.

In another alternative embodiment, the first indication information may be carried by a reserved bit in the remaining power message. For example, one or more reserved bits 503 in fig. 5 may be used to carry the first indication information. The corresponding relation between the preset value of the preset bit of the first remaining power message and the reason for changing the state of the first antenna panel can be preset, and the network device determines the reason for changing the state of the first antenna panel according to the preset corresponding relation between the preset value of the preset bit of the first remaining power message and the reason for changing the state of the first antenna panel and the value set by the preset bit of the first remaining power message.

For example, when the 1 st reserved bit of the first remaining power packet is 1, the reason for changing the state of the corresponding first antenna panel is as follows: the terminal equipment stops using the first antenna panel; when the 2 nd reserved bit of the first remaining power packet is 1, the reason for the state change of the corresponding first antenna panel is as follows: the terminal equipment encounters the problem of ultra MPE; when the 3 rd reserved bit of the first remaining power packet is 1, the reason for the state change of the corresponding first antenna panel is as follows: the terminal device enables other antenna panels for data transmission.

In step 403, the first remaining power message may further include second indication information, where the second indication information is used to indicate an identifier of the second antenna panel and a status of the second antenna panel; the second antenna panel includes one or more antenna panels of the terminal device other than the first antenna panel. That is, when the terminal device has a plurality of antenna panels, in the remaining power message triggered by the change of the first antenna panel from the activated state to the deactivated state, in addition to the change of the first antenna panel to the deactivated state, the states of other antenna panels may be indicated. For example, the reserved bits in the remaining power message may be used to carry the second indication information, such as the status of several antenna panels of the terminal device may be notified in a binary number manner or in a bit map manner. For example, the reserved bit of the remaining power message is located in the corresponding relationship of the antenna panels, when a preset bit is 1, it indicates that the antenna panel corresponding to the reserved bit is in the deactivated state, and when the preset bit is 0, it indicates that the antenna panel corresponding to the reserved bit is in the activated state.

In another optional implementation manner, a corresponding relationship between the first preset value and the second preset value combination and the identifier of the antenna panel and the state of the antenna panel may be preset, and the network device determines the identifier and the state of each antenna panel indicated by the remaining message according to the received first preset value and the received second preset value, and the corresponding relationship between the first preset value and the second preset value combination and the identifier of the antenna panel and the state of the antenna panel. That is, by setting the output power to the first preset value corresponding to the first antenna panel and/or setting the remaining power to the second preset value corresponding to the first antenna panel, it is indicated that the first antenna panel is currently changed from the activated state to the deactivated state, and the identifier and the state of the second antenna panel may also be indicated. For example, when the output power is set to 000000 and the remaining power is set to 000000, it may indicate that the antenna panel #1 is no longer used for data transmission (in a deactivated state), and if the first antenna panel is the antenna panel #1, the network device receives the remaining power message, and may determine that the first antenna panel currently used for transmission is no longer used for data transmission. For another example, setting the output power to 000001 and setting the remaining power to 000001 may indicate that the antenna panel #2 is no longer used for data transmission (is in a deactivated state), and if the first antenna panel is the antenna panel #1, the network device receives the remaining power packet, may determine that the first antenna panel currently used for transmission is no longer used for data transmission, and may also determine that the antenna panel #2 is no longer used for data transmission.

Step 404 may be performed after step 403, as described above, and after step 302 of fig. 3, as described above.

Step 404, the third antenna panel of the terminal device is switched from the deactivated state to the activated state, and sends the second remaining power packet to the network device.

Correspondingly, the network equipment receives a second residual power message sent by the terminal equipment; the second remaining power message is sent when a third antenna panel of the terminal equipment is switched from a deactivation state to an activation state; and the network equipment determines that the third antenna panel is switched from the deactivation state to the activation state according to the second residual power message.

That is, in the embodiment provided in step 404, a new remaining power message trigger condition is set, i.e., the antenna panel is switched from the deactivated state to the activated state. Therefore, the purpose of state synchronization of the antenna panel of the terminal equipment can be achieved by utilizing the existing residual power message.

The step 404 can also be described as: when the absolute value of the variation of the output power of the third antenna panel of the terminal device is greater than or equal to the output power variation threshold: a notification message is sent to the network device. It can also be described as: and if the absolute value of the variation of the output power of the third antenna panel of the terminal equipment is greater than or equal to the threshold of the variation of the output power, triggering the report of the notification message.

When the notification message is a remaining power message, it may also be described that an absolute value of a variation of the output power of the third antenna panel of the terminal device is greater than or equal to an output power variation threshold, and then reporting of the second remaining power message is triggered. That is, a condition is set for reporting the remaining power message, that is: the absolute value of the amount of change in the output power of the second antenna panel of the terminal device is greater than or equal to the output power change amount threshold.

In step 404, in an optional implementation manner, when the third antenna panel is in the deactivated state, the output power and the remaining power of the third antenna panel may return to zero. When the third panel is in the active state, the output power of the third panel is typically a non-zero value. In this case, the variation of the output power of the third antenna panel is a difference between the output power of the third antenna panel in the activated state and zero, and it can be seen that the variation of the output power of the third antenna panel is large and larger than a preset threshold of the variation of the output power. In practical applications, since the output power of the third antenna panel in the activated state may be a negative number, the variation of the output power of the third antenna panel may be a negative number, in which case the absolute value of the variation of the output power may be taken, and then the absolute value of the variation of the output power may be compared with the threshold of the variation of the output power. The threshold of the output power variation may be preset, or may be issued by the network device, or may be negotiated between the base station and the network device through some signaling, for example, the network device may configure the threshold of the output power variation for the terminal device in step 401.

In step 404, when the terminal device currently performs data transmission only through the third antenna panel, the output power field of the terminal device in the second remaining power message is the output power of the third antenna panel, and the remaining power field of the terminal device in the second remaining power message is the remaining power of the third antenna panel.

In step 404, the second remaining power message may further include the second indication information, where the second indication information is used to indicate an identifier of the second antenna panel and a state of the second antenna panel; the second antenna panel includes one or more antenna panels of the terminal device other than the first antenna panel. That is, when the terminal device has a plurality of antenna panels, the second remaining power message triggered by the change of the third antenna panel from the deactivated state to the activated state may indicate the states of other antenna panels in addition to the change of the third antenna panel to the activated state. For example, the reserved bits in the remaining power message may be used to carry the second indication information, such as the status of several antenna panels of the terminal device may be notified in a binary number manner or in a bit map manner. For example, the reserved bit of the remaining power message is located in the corresponding relationship of the antenna panels, when a preset bit is 1, it indicates that the antenna panel corresponding to the reserved bit is in the deactivated state, and when the preset bit is 0, it indicates that the antenna panel corresponding to the reserved bit is in the activated state.

After the above step 404, a step 405 may be performed.

Step 405, the network device schedules the antenna panel in the activated state on the terminal device according to the state of the antenna panel of the terminal device.

It can be seen from the above content that, in the embodiment of the present application, the terminal device completes the switching process of the antenna panel through the steps 401 to 405, that is, the terminal device switches from the first antenna panel to the third antenna panel, and in the switching process of the antenna panel, the state of the antenna panel of the terminal device is synchronized to the network device, so that the network device schedules the antenna panel according to the state of the antenna panel, and in the scheduling process, the network device can avoid scheduling the antenna panel in the deactivated state, thereby improving the success rate of data transmission of the network device. And the embodiment shown in fig. 4 completes the switching of the antenna panel and the state synchronization problem of the antenna panel by using the residual power message in the prior art, and the solution is compatible with the prior art and has less changes.

With respect to step 301 in fig. 3, another possible implementation manner may be provided in this embodiment, in this implementation manner, the notification message in step 301 may not be the remaining power message multiplexed in fig. 4, and may be a newly defined signaling. The notification message may be triggered when the state of the antenna panel of the terminal device changes from an active state to a deactivated state, upon receipt of which the network device determines that the antenna panel currently in use is no longer used for transmission.

In this embodiment, the notification message may occupy as few bytes as possible, for example, may be signaling that occupies only 1 bit, and thus, as little information as possible may be used to notify the network device that the state of the first antenna panel is changed from activation to deactivation. In this embodiment, step 401 and step 402 may also be performed before step 301. In this embodiment, the above-mentioned

steps

404 and 405 may also be performed.

In an optional implementation manner, further, after the terminal device sends the notification message to the network device, and after the network device receives the notification message, the terminal device may schedule uplink resources to the terminal device according to the notification message, so as to trigger the terminal device to send the remaining power packet. In this case, it can be said that the reporting condition of the remaining power message is: the terminal equipment sends a notification message to the network equipment and receives the indication information of the uplink resource scheduled by the network equipment for the terminal equipment.

In another optional implementation manner, further, after the terminal device sends the notification message to the network device, the remaining power reporting may be automatically triggered. In this case, it can be said that the reporting condition of the remaining power message is: the terminal device sends a notification message to the network device.

Further, in a possible implementation manner, the notification message may further include an identifier of the first antenna panel, so that the network device may determine, after receiving the notification message, that the state of the first antenna panel is changed from the deactivated state to the activated state according to the notification message.

Further, in a possible implementation manner, the notification message may further include first indication information, where the first indication information is used to indicate a reason for changing the state of the first antenna panel.

Further, in a possible embodiment, the notification message may further include second indication information, where the second indication information is used to indicate an identifier of the second antenna panel and a status of the second antenna panel; the second antenna panel includes one or more antenna panels of the terminal device other than the first antenna panel. That is, when the terminal device has a plurality of antenna panels, the notification message triggered by the first antenna panel changing from the activated state to the deactivated state may indicate the state of another antenna panel in addition to the first antenna panel changing to the deactivated state.

It can be seen from the above that, in the foregoing step 301, the terminal device in this embodiment may set the notification message as a newly defined signaling, and in this embodiment, when the antenna panel of the terminal device is switched from the deactivated state to the activated state, the foregoing step 404 may also be executed. In addition, in the embodiment, the notification message can be set as a newly defined signaling, so that the data transmission amount can be reduced by reducing the bit occupied by the notification message, and the uplink data resource can be saved.

Fig. 1 in the embodiment of the present application exemplarily shows a possible structure schematic diagram of a terminal device, and as shown in fig. 1, the terminal device is configured with a plurality of antenna panels. In the embodiment of the application, data transmission between the terminal device and the network device through a plurality of antenna panels can also be supported. The notification message in the embodiment of the present application may carry the status of each of the plurality of antenna panels. Further, optionally, the notification message may also carry the remaining power of the terminal device and the output power of the terminal device.

The notification message may be a newly defined signaling, or may multiplex the remaining power message, specifically, optionally, the first remaining power message further includes: the remaining power and the output power of the fourth antenna panel; the fourth antenna panel comprises one or more antenna panels in the terminal device; the remaining power of the terminal device and the output power of the terminal device. In this case, the first remaining power packet and the second remaining power packet may have a number of extension fields more than the remaining power packet in the related art.

The first remaining power message and the second remaining power message may also be referred to as extended remaining power messages. The remaining power and the output power of each of the plurality of antenna panels carried in the first remaining power message may be carried in an extension field of the first remaining power message. Fig. 6 exemplarily shows a schematic structural diagram of an extended remaining power packet in an embodiment of the present application. The schematic structural diagram of the extended remaining power packet shown in fig. 6 may be a schematic structural diagram of a first remaining power packet, or may be a schematic structural diagram of a second remaining power packet. As shown in fig. 6, the expanding the remaining power message may include: a field 601 for carrying the remaining power of the terminal device, a field 602 for carrying the output power of the terminal device, a field 603 for carrying the remaining power of the antenna panel #1 of the terminal device, a field 604 for carrying the output power of the antenna panel #1 of the terminal device, a field 605 for carrying the remaining power of the antenna panel #2 of the terminal device, a field 606 for carrying the output power of the antenna panel #2 of the terminal device, and some reserved bits 607. In fig. 6, the antenna panel #1 and the antenna panel #2 of the terminal device are only described as an example, and if the output power and the remaining power of one or more other antenna panels need to be carried, the first remaining power message and the second remaining power message may be further extended.

In a possible embodiment, the output power of the terminal device may be the maximum of the output powers of all antenna panels in the active state on the terminal device. For example, the antenna panels currently activated on the terminal device are antenna panel #1 and antenna panel # 2. When the terminal device uses the antenna panel #1 alone to perform data transmission, the output power of the antenna panel #1 is 23dBm, when the terminal device uses the antenna panel #2 alone to perform data transmission, the output power of the antenna panel #2 is 20dBm, when the terminal device uses the antenna panel #1 and the antenna panel #2 together to perform data transmission, the output power of the terminal device is the output power of the antenna panel #1 when the terminal device uses the antenna panel #1 alone to perform data transmission, and when the terminal device uses the antenna panel #2 alone to perform data transmission, the output power of the terminal device is 23dBm, which is the larger value of the output power of the antenna panel # 2. When the terminal device uses a plurality of antenna panels to perform data transmission with the network device at the same time, each antenna panel can equally divide the output power of the terminal device, that is, when the output power of the terminal device is 23dBm, and the antenna panel #1 and the antenna panel #2 are simultaneously used to perform uplink data transmission, the output power of each antenna panel is 20 dBm. The parameters in this example may be as shown in table 5 below.

TABLE 5 output power schematic of terminal device

In a possible implementation manner, the remaining power of the terminal device may be reported according to an actual situation, for example, the remaining power of the terminal device may be determined according to the remaining power of each antenna panel currently performing data transmission, if one antenna panel is used alone to perform data transmission, the remaining power of the terminal device is the remaining power of the antenna panel, and if two antenna panels are used simultaneously to perform data transmission, the remaining power of the terminal device is the sum of the remaining powers of the two antenna panels.

Further, optionally, the remaining power field and/or the output power field of an individual antenna panel in the structure of expanding the remaining power shown in fig. 6 may be used to indicate the status of a single antenna panel. For example, as shown in fig. 6, when the antenna panel #1 is in a deactivated state, a value of at least one of a field 603 for carrying remaining power of the antenna panel #1 of the terminal device and a field 604 for carrying output power of the antenna panel #1 of the terminal device may be set to a preset value. That is, in one possible embodiment, when the fourth antenna panel is in the deactivated state: the remaining power of the fourth antenna panel carried in the first remaining message is a third preset value, and/or the output power of the fourth antenna panel is a fourth preset value. Correspondingly, when the remaining power of the fourth antenna panel carried in the first remaining packet is a third preset value, the output power of the fourth antenna panel is a fourth preset value: the network device determines that the fourth antenna panel is in a deactivated state. In an optional embodiment, the third preset value and the fourth preset value are both set to 0.

Fig. 7 is a schematic flowchart illustrating a method for notifying an antenna panel state according to an embodiment of the present application, and as shown in fig. 7, the method includes:

step 701, the terminal device reports the capability parameter of the terminal device, and the network device configures the parameter corresponding to the terminal device.

This step 701 is the same as the step 401 described above.

Step 702, when the terminal device monitors that the state of any one or more antenna panels changes, a third remaining power message is triggered.

In this step, when the terminal device monitors that the state of the antenna panel is changed from activation to deactivation, the third remaining power message may be the first remaining power message in the content, and when the terminal device monitors that the state of the antenna panel is changed from deactivation to activation, the third remaining power message may be the second remaining power message of the content. The third remaining power message and the previous "third", "first" and "second" in the first remaining power message and the second remaining power message are only used for distinguishing the remaining power messages, and have no limiting meaning. The formats of the first remaining power message, the second remaining power message, and the third remaining power message may be the format of the extended remaining power message in fig. 6.

And bearing the output power and the residual power of each antenna panel in a third residual power message, wherein when the state of the antenna panel is in a deactivated state, the bearing content of an output power field for bearing the antenna panel in the third residual power message is a fourth preset value, and/or the bearing content of a residual power field for bearing the antenna panel is a third preset value.

In this step 702, the terminal device monitors that the state of any one or any plurality of antenna panels changes, which may be monitoring that the state of any one or more antenna panels changes from an activated state to a deactivated state; or the state of any one or more antenna panels can be monitored to be changed from the deactivation state to the activation state; it may also be that it is monitored that the state of any one or more antenna panels is changed from the activated state to the deactivated state, and the state of any one or more antenna panels is changed from the deactivated state to the activated state.

For step 702, by way of example with reference to the example of table 5, fig. 8, fig. 9, and fig. 10 respectively show schematic diagrams of content carried by a third remaining power message according to an embodiment of the present application. When the third remaining power packet structure of the terminal device is as shown in fig. 6, and when the terminal device performs data transmission only using the antenna panel #1, the numerical value carried by each field of the third remaining power packet is as shown in fig. 8, the content carried by the field 601 for carrying the remaining power of the terminal device is 2dB, the content carried by the field 602 for carrying the output power of the terminal device is 23dBm, the content carried by the field 603 for carrying the remaining power of the antenna panel #1 of the terminal device is 2dB, the content carried by the field 604 for carrying the output power of the antenna panel #1 of the terminal device is 23dBm, the content carried by the field 605 for carrying the remaining power of the antenna panel #2 of the terminal device is 0dB, and the content carried by the field 606 for carrying the output power of the antenna panel #2 of the terminal device is 0 dBm.

When the terminal device performs data transmission only using the antenna panel #2, the values carried by the fields of the third remaining power packet are as shown in fig. 9, the content carried by the field 601 for carrying the remaining power of the terminal device is 3dB, the content carried by the field 602 for carrying the output power of the terminal device is 20dBm, the content carried by the field 603 for carrying the remaining power of the antenna panel #1 of the terminal device is 0dB, the content carried by the field 604 for carrying the output power of the antenna panel #1 of the terminal device is 0dBm, the content carried by the field 605 for carrying the remaining power of the antenna panel #2 of the terminal device is 3dB, and the content carried by the field 606 for carrying the output power of the antenna panel #2 of the terminal device is 20 dBm.

When the terminal device uses the antenna panel #1 and the antenna panel #2 to perform data transmission, the values carried by the fields of the third remaining power packet are as shown in fig. 10, the content carried by the field 601 for carrying the remaining power of the terminal device is 5dB, the content carried by the field 602 for carrying the output power of the terminal device is 23dBm, the content carried by the field 603 for carrying the remaining power of the antenna panel #1 of the terminal device is 2dB, the content carried by the field 604 for carrying the output power of the antenna panel #1 of the terminal device is 20dBm, the content carried by the field 605 for carrying the remaining power of the antenna panel #2 of the terminal device is 3dB, and the content carried by the field 606 for carrying the output power of the antenna panel #2 of the terminal device is 20 dBm.

Step 703, the network device schedules the antenna panel in the activated state on the terminal device according to the state of the antenna panel of the terminal device and the remaining power and output power of the terminal device.

As can be seen from the embodiment shown in fig. 7, the embodiment of the present application can support simultaneous invocation of multiple antenna panels, and the embodiment of the present application can be compatible with a reporting mechanism of a residual power message in the prior art, and implement synchronization of states of antenna panels of a terminal device by using a scheme of extending the residual power message, so that when the terminal device implements switching of the antenna panels, a network device schedules an antenna panel in an active state, thereby improving a success rate of data transmission.

According to the foregoing method, fig. 11 is a schematic structural diagram of a communication device provided in this embodiment of the present application, and as shown in fig. 11, the communication device may be a terminal device or a network device, or may be a chip or a circuit, for example, a chip or a circuit that may be disposed in the terminal device, or further, for example, a chip or a circuit that may be disposed in the network device.

Further, the communication device 1101 may further include a bus system, wherein the processor 1102, the memory 1104 and the transceiver 1103 may be connected via the bus system.

It is to be understood that the processor 1102 may be a chip.
