The cell may be a unit for managing wireless communication from the viewpoint of higher-layer resource management. A cell may include a carrier. Depending on the duplex mode, the downlink carrier and the uplink carrier of a cell may be different (e.g., in a frequency division duplex (FDD, frequency division duplex) system), and the downlink carrier and the uplink carrier of a cell may be the same (e.g., in a time division duplex (TDD, time division duplex) system). In carrier aggregation/dual-link, a part of cells may contain both downlink and uplink carriers, and a part of cells may contain only downlink carriers.

It may be understood that, the communication system described in the embodiments of the present application is for more clearly describing the technical solution of the embodiments of the present application, and is not limited to the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiments of the present application is equally applicable to similar technical problems.

With the development of communication networks, a relay device controlled by a network, which may also be called an intelligent relay device or a relay device for amplifying signals in a directional manner, is expected to become a key technology for expanding the coverage area of a cell. The downlink signal of the base station is received by the UE after being amplified by the intelligent relay equipment, and correspondingly, the uplink signal of the UE is also received by the base station after being amplified by the intelligent relay equipment.

The intelligent relay equipment can send two uplink signals, including the uplink signal forwarded by the intelligent relay equipment and the uplink signal generated by the intelligent relay equipment. In order to avoid interference to other UEs in the cell, the base station needs to control the uplink signal generated by the intelligent relay device and the transmission power of the forwarded uplink signal.

Therefore, the present disclosure provides a method and an apparatus for determining transmission power, where an intelligent relay device can determine transmission power of an uplink signal according to transmission power control information sent by a network device, so as to ensure stability of reception power of the network device when receiving the signal, and ensure that interference is not generated on uplink signals of other users in the network.

The method and apparatus for determining transmission power provided in the present application are described in detail below with reference to the accompanying drawings.

Fig. 2 shows a flow diagram of a transmit power determination method according to an embodiment of the present disclosure. As shown in fig. 2, the method may be performed by an intelligent relay device and includes the following steps.

S201, receiving transmission power control information sent by the network device, where the transmission power control information includes at least one power indication for indicating a transmission power used by the intelligent relay device to send the signal.

The network device may transmit power control information, which may be, for example, transmit power control (Transmitting Power Control, TPC) commands, to the intelligent relay device, the transmit power control information including at least one power indication indicating the transmit power employed by the intelligent relay device to transmit the signal.

The transmission power control information may be transmitted by downlink control information (Downlink Control Information, DCI).

S202, determining the transmission power based on at least one power indication.

After receiving the transmission power control information, the intelligent relay device may determine the transmission power used for transmitting the signal based on at least one power indication included in the transmission power control information.

In some embodiments, the intelligent relay device may determine the transmit power employed to transmit the signal based on the pre-configured power control mode and at least one power indication included in the transmit power control information.

The preconfigured power control mode may be agreed in advance by the intelligent relay device and the network device, or may be signaled to the intelligent relay device by the network device through radio resource control (Radio Resource Control, RRC).

The preconfigured power control modes may include a closed loop power control mode, as well as a combined power control mode. In the closed-loop power control mode, the intelligent relay equipment only performs closed-loop power control; in the combined power control mode, the intelligent relay device performs open loop power control first and then closed loop power control.

According to the transmission power determining method of the embodiment of the disclosure, the intelligent relay device receives transmission power control information sent by the network device, wherein the transmission power control information comprises at least one power indication for indicating transmission power adopted by the intelligent relay device for transmitting signals, and the intelligent relay device determines the transmission power based on the at least one power indication. Therefore, the network equipment can adjust the sending power of the uplink signals sent by the intelligent relay equipment, thereby ensuring the stability of the receiving power of the network equipment when receiving the signals and ensuring that the uplink signals of other users in the network are not interfered.

Fig. 3 shows a flow diagram of a transmit power determination method according to an embodiment of the present disclosure. As shown in fig. 3, the method may be performed by an intelligent relay device, which may have one or more available resource objects, wherein the available resource objects may include one or more of available antenna ports, available frequency bands, and available channels, and the transmission power determination method may include the following steps.

S301, receiving transmission power control information sent by a network device, where the transmission power control information includes at least one power indication for indicating a transmission power employed by an intelligent relay device to send a signal, and power application information for indicating an available resource object for which each power indication is available.

The network device may send transmit power control information, which may be, for example, TPC commands, to the intelligent relay device, the transmit power control information including at least one power indication and power application information indicating available resource objects for which each power indication is available, e.g., antenna ports and/or frequencies and/or uplink control channels and/or uplink data channels for which each power indication is available, etc.

The transmission power control information may be transmitted through DCI.

In some embodiments, if the transmit power control information includes a power indication, the available resource object to which the power indication is applicable is indicated by a particular field in the transmit power control information. For example, at least two fields in DCI are used to represent transmit power control information, one field (TPC field) represents power indication and one field represents power application information. Wherein a field representing the power application information indicates an available resource object to which the power indication is applicable, e.g. an antenna port and/or a frequency band and/or an uplink control channel and/or an uplink data channel, etc., which field indicates in particular which available resource object is configurable by the network device by RRC signaling.

In some embodiments, if the transmission power control information includes a plurality of power indicators, the plurality of power indicators are represented by a plurality of positions in the transmission power control information, where each power indicator is applicable to an available resource object determined based on a position where the power indicator is located and a preset position correspondence. For example, there are a plurality of positions of at least one field in the DCI, one position (tpc#1) represents power indication 1, one position (tpc#2) represents power indication 2, where the preset position correspondence indicates that position tpc#1 corresponds to resource object 1, and position tpc#2 corresponds to resource object 2.

It is assumed that the available antenna ports of the intelligent repeater apparatus include antenna ports 1-7, and that the available frequency bands of the intelligent repeater apparatus include frequency bands 1-3, and that the available channels include uplink channels 1-2.

In an example, the transmission power control information sent by the network device to the intelligent relay device includes a power indication 1 and power application information. For example, the power application information may indicate that power indication 1 is available for antenna ports 1-3. As another example, the power application information may indicate that power indication 1 is available for band 1. As another example, the power application information may indicate that power indication 1 is available for uplink channel 1. As another example, the power application information may indicate that power indication 1 is available for antenna ports 1-3 as well as band 1.

In the above example, the transmission power control information includes one power indication of power indication 1, and the power application information may be represented by a specific field in the transmission power control information. For example, if a particular field indicates antenna port 1-3, it indicates that power application information in the transmit power control information indicates that power indication 1 is available for antenna port 1-3. As another example, if the specific field indicates band 1, it indicates that the power application information in the transmission power control information indicates that power indication 1 is available for band 1. As another example, if the specific domain indicates the uplink channel 1, it indicates that the power application information in the transmission power control information indicates that the power indication 1 is available for the uplink channel 1. As another example, if the specific field indicates antenna port 1-3 and band 1, it indicates that the power application information in the transmit power control information indicates that power indication 1 is available for antenna port 1-3 and band 1.

In another example, the network device includes two power indications 1-2 and power application information in the transmit power control information sent to the intelligent relay device. For example, the power application information may indicate that power indication 1 is available for antenna ports 1-3 and power indication 2 is available for antenna ports 4-7. As another example, the power application information may indicate that power indication 1 is available for band 1 and power indication 2 is available for bands 2-3. As another example, the power application information may indicate that power indication 1 is available for uplink channel 1 and power indication 2 is available for uplink channel 2. As another example, the power application information may indicate that power indication 1 is available for antenna port 1-3 and band 1, and power indication 2 is available for antenna port 4-7 and band 2-3.

In the above example, two power indications of power indications 1-2 are included in the transmission power control information, and the power application information may be represented by representing a plurality of power indications at a plurality of positions in the transmission power control information. It is assumed that the first bit of the particular field represents a power indication 1 and the second bit represents a power indication 2. For example, the preset position correspondence indicates that the first bit corresponds to the antenna port 1-3 and the second bit corresponds to the antenna port 4-7, and then indicates that the power application information in the transmission power control information indicates that the power indication 1 is available for the antenna port 1-3 and the power indication 2 is available for the antenna port 4-7. For another example, the preset position corresponding relation indicates that the first bit corresponds to the frequency band 1, and the second bit corresponds to the frequency band 2-3, and then indicates that the power application information in the transmission power control information indicates that the power indication 1 can be used for the frequency band 1, and the power indication 2 can be used for the frequency band 2-3. For another example, the preset position corresponding relation indicates that the first bit corresponds to the uplink channel 1, and the second bit corresponds to the uplink channel 2, and indicates that the power application information in the transmission power control information indicates that the power indication 1 can be used for the uplink channel 1 and the power indication 2 can be used for the uplink channel 2. For another example, the preset position corresponding relation indicates that the first bit corresponds to the antenna port 1-3 and the frequency band 1, and the second bit corresponds to the antenna port 4-7 and the frequency band 2-3, and then indicates that the power application information in the transmission power control information indicates that the power indication 1 can be used for the antenna port 1-3 and the frequency band 1, and the power indication 2 can be used for the antenna port 4-7 and the frequency band 2-3.

S302, based on each power indication, a transmission frequency is determined for an available resource object to which the power indication is applicable.

After receiving the transmission power control information, the intelligent relay device may determine, based on each power indication included in the transmission power control information, a transmission power employed by the intelligent relay device to transmit a signal using an available resource object for which the power indication is available. In some embodiments, the intelligent relay device may determine, based on each power indication included in the transmit power control information and a pre-configured power control mode corresponding to an available resource object for which the power indication is available, a transmit power with which the intelligent relay device transmits signals using the available resource object for which the power indication is available.

The preconfigured power control mode may be pre-agreed by the intelligent relay device and the network device, or may be notified to the intelligent relay device by the network device through RRC signaling.

Referring to the above example, when the intelligent trunk device receives power indication 1 and power application information indicating that power indication 1 is available for antenna port 1-3, the intelligent trunk device may determine transmit power based on power indication 1 when transmitting signals on antenna port 1-3, e.g., in some embodiments, the intelligent trunk device may determine the transmit power based on power indication 1 and a preconfigured power control mode corresponding to the antenna port 1-3.

As another example, when the intelligent repeater unit receives power indication 1-2 and power application information indicating that power indication 1 is available to antenna port 1-3 and power indication 2 is available to antenna port 4-7, the intelligent repeater unit can determine a transmit power based on power indication 1 when transmitting signals on antenna port 1-3, e.g., in some embodiments, the intelligent repeater unit can determine the transmit power based on power indication 1 and a preconfigured power control mode corresponding to antenna port 1-3; the transmit power is determined based on the power indication 2 when transmitting signals on the antenna ports 4-7, e.g., in some embodiments, the intelligent repeater unit may determine the transmit power based on the power indication 2 and a pre-configured power control mode corresponding to the antenna ports 4-7.

As another example, when the intelligent trunk device receives power indication 1-2 and power application information indicating that power indication 1 is available for band 1 and power indication 2 is available for band 2-3, the intelligent trunk device may determine transmit power based on power indication 1 when transmitting signals on band 1, e.g., in some embodiments, the intelligent trunk device may determine the transmit power based on power indication 1 and a preconfigured power control mode corresponding to band 1; the transmit power is determined based on power indication 2 when transmitting signals on frequency band 2-3, e.g., in some embodiments, the intelligent relay device may determine the transmit power based on power indication 2 and a pre-configured power control mode corresponding to frequency band 2-3.

According to the transmission power determining method of the embodiment of the disclosure, the intelligent relay device receives transmission power control information transmitted by the network device, wherein the transmission power control information comprises a plurality of power indications for indicating transmission power adopted by the intelligent relay device for transmitting signals and power application information for indicating antenna ports and/or frequency bands to which each power indication can be applied, and the intelligent relay device determines the transmission power adopted when transmitting signals on the corresponding antenna ports and/or frequency bands based on each power indication. Therefore, the network equipment can adjust the sending power of the uplink signals sent by the intelligent relay equipment, thereby ensuring the stability of the receiving power of the network equipment when receiving the signals and ensuring that the uplink signals of other users in the network are not interfered.

Fig. 4 shows a flow diagram of a transmission power determination method according to an embodiment of the present disclosure, which may be performed by an intelligent relay device based on the embodiments shown in fig. 2 and 3, as shown in fig. 4, and may include the following steps.

S401, receiving the transmission power control information sent by the network device.

In some embodiments, the transmit power control information includes at least one power indication for indicating a transmit power at which the intelligent relay device transmits signals.

In some embodiments, the transmit power control information includes at least one power indication for indicating a transmit power employed by the intelligent relay device to transmit the signal and power application information for indicating available resource objects for which each power indication is available.

The transmission power control information may be transmitted through DCI.

For the description and specific details of step S401 above, reference may be made to the relevant descriptions and details of steps S201 and S301 above.

S402, determining the transmission power based on the transmission power control information.

The intelligent relay device can send two uplink signals, including an uplink signal forwarded by the intelligent relay device and an uplink signal generated by the intelligent relay device. Typically, the intelligent repeater unit may employ some specific resource objects to transmit its own generated uplink signals and other specific resource objects to transmit the forwarded uplink signals.

In some embodiments, when the transmit power control information includes only a power indication, the intelligent relay device can determine the transmit power employed in transmitting the signal based on the power indication. For the description and specific details of this embodiment, reference may be made to the above description and details of step S202, which are not repeated herein.

For example, as for transmission power control information including only a power indication, which is indicated by RRC signaling by the network device or previously agreed by the intelligent relay device and the network device, the power indication in the transmission power control information may be applied to a specific resource object used by the intelligent relay device when transmitting a signal generated by itself, and the intelligent relay device may determine the transmission power employed when transmitting a signal generated by itself using the corresponding resource object based on the power indication.

As another example, with respect to the transmission power control information including only the power indication, which is indicated by the network device through RRC signaling or previously agreed by the intelligent relay device and the network device, the power indication in the transmission power control information may be applied to a specific resource object used by the intelligent relay device when transmitting the forwarded signal, and the intelligent relay device may determine the transmission power employed when transmitting the forwarded signal using the corresponding resource object based on the power indication.

As another example, the network device indicates through RRC signaling or the intelligent relay device and the network device agree in advance that, for the transmission power control information including only the power indication, the power indication in the transmission power control information may be applied to all available resource objects of the intelligent relay device, and then the intelligent relay device may determine the transmission power employed when transmitting signals using any available resource object based on the power indication.

In other embodiments, when the transmit power control information includes only power indications and power application information indicating available resource objects to which each power indication is applicable, the intelligent relay device can determine a transmit frequency for the available resource objects to which the power indication is applicable based on each power indication. For the description and specific details of this embodiment, reference may be made to the above description and details of step S302, which are not repeated herein.

For example, the transmission power control information includes one power indication and power application information, wherein the power application information indicates that the one power indication can be applied to a specific resource object used by the intelligent relay device when transmitting the self-generated signal, and the intelligent relay device can determine the transmission power employed when transmitting the self-generated signal based on the power indication and the power application information.

If the transmission power control information includes a power indication, the power indication is indicated by a specific field in the transmission power control information to be applicable to the available resource object.

For example, the transmission power control information includes a plurality of power indications and power application information, wherein the power application information indicates that the plurality of power indications may be applied to a specific resource object used by the intelligent trunk device when transmitting the self-generated signal and to other specific resource objects used when transmitting the forwarded signal, respectively, and the intelligent trunk device is able to determine a first transmission power employed when transmitting the self-generated signal and a second transmission power employed when transmitting the forwarded signal based on the plurality of power indications and the power application information.

And if the transmission power control information comprises a plurality of power indications, the plurality of power indications are represented by a plurality of positions in the transmission power control information, wherein each power indication can be applied to the available resource object and is determined based on the position of the power indication and the corresponding relation of the preset position.

In some embodiments, step S402 may include determining the transmit power based on the pre-configured power control mode and the transmit power control information.

In open loop power control, the intelligent relay device may determine an open loop transmit power. In the closed loop power control, the intelligent relay device may adjust the currently available transmission power based on the power indication included in the transmission power control information to determine the transmission power, where the currently available transmission power may be the open loop transmission power determined in the open loop power control, the transmission power after being adjusted and determined in the last closed loop power control, or the preset power. Specifically, the power indication may include an absolute difference value or a cumulative difference value, and whether the power indication includes an absolute difference value or a cumulative difference value may be configured by the RRC. If the power indication comprises an absolute difference value, the currently available transmitting power is a preset power or an open loop transmitting power; if the accumulated differential value is included in the power indication, the currently available transmit power is the previously determined transmit power.

When the absolute difference value is included in the power indication and the preconfigured power control mode is the combined power control mode, the above-described step S402 may be implemented as follows.

S4021, performing power measurement to determine path loss power based on a system message and a downlink reference signal sent by a network device; determining an open loop transmit power based on the path loss power and the target receive power; and adjusting the open loop transmit power based on the absolute differential value to determine the transmit power.

If the absolute difference value is included in the power indication and the pre-configured power control mode is the combined power control mode, the intelligent relay device needs to perform open loop power control to determine open loop transmit power first, and then perform closed loop power control to adjust the determined open loop transmit power based on the absolute difference value.

Under open loop power control, the network device sends target receiving power to the intelligent relay device through a system broadcast message, the intelligent relay device performs power measurement through a received downlink reference signal to calculate path loss power, and the intelligent relay device can determine open loop sending power based on the target receiving power and the path loss power after obtaining the path loss power because the uplink and downlink channel frequency bands are equivalent and channel condition conversion is smaller in a short time.

Under closed loop power control, the intelligent relay device transmits an uplink signal according to open loop transmission power, and the network device performs power adjustment according to a signal-to-interference-and-noise ratio (Signal to Interference plus Noise Ratio, SINR) or a Block Error Rate (BLER) reported by the intelligent relay device in combination with a target SINR and a target BLER. Specifically, the power indication sent by the network device to the intelligent relay device includes an absolute difference value, and the intelligent relay device adjusts the open loop transmission power according to the absolute difference value to determine the transmission power when transmitting the signal.

When the absolute difference value is included in the power indication and the preconfigured power control mode is the closed loop power control mode, the above step S402 may be implemented as follows.

S4022, adjusting the preconfigured power based on the absolute difference value to determine the transmission power.

If the absolute difference value is included in the power indication and the pre-configured power control mode is a closed loop power control mode, the intelligent relay device needs to execute closed loop power control to adjust the pre-configured power based on the absolute difference value.

Specifically, the power indication sent by the network device to the intelligent relay device includes an absolute difference value, and the intelligent relay device adjusts the preset power according to the absolute value to determine the sending power when sending the signal.

In some embodiments, the preconfigured power is a default power value or an initial power value indicated by RRC signaling sent by the network device. The default power value may be a default maximum power value.

For example, the absolute difference value may always be a positive number, and the intelligent relay device subtracts the absolute difference value from the default power value to determine the transmission power.

As another example, the network device sends the initial power value to the intelligent relay device through RRC signaling, the absolute difference value may be positive or negative, and the intelligent relay device adds or subtracts the absolute difference value to determine the transmission power based on the initial power value.

When the integrated differential value is included in the power indication, the above step S402 may be implemented as follows.

S4023, adjusting the currently available transmission power based on the accumulated differential value to determine the transmission power.

The power indication sent by the network device to the intelligent relay device includes a cumulative differential value. And the network equipment considers that the power adjustment is needed according to the power measurement result of the uplink signal, and then the network equipment transmits the transmission power control information comprising the accumulated differential value to the intelligent relay equipment.

If the accumulated differential value is included in the power indication, the intelligent trunk device adjusts based on the currently available transmit power (i.e., the transmit power used for the last time the signal was transmitted), regardless of whether the preconfigured power control mode is a combined power control mode or a closed loop power control mode.

For example, when the power adjustment value is the cumulative differential value, the intelligent relay device adjusts according to the transmission power used for transmitting the signal last time, for example, P (i) last time, and then P (i+1) =p (i) +/-the cumulative differential value next time.

In some embodiments, the intelligent relay device may determine the transmit power employed to transmit the signal based on the pre-configured power control mode and at least one power indication included in the transmit power control information. The preconfigured power control mode may be agreed in advance by the intelligent relay device with the network device or may be signaled to the intelligent relay device by the network device through radio resource control (Radio Resource Control). The preconfigured power control modes may include a closed loop power control mode, as well as a combined power control mode. In the closed-loop power control mode, the intelligent relay equipment only performs closed-loop power control; in the combined power control mode, the intelligent relay device performs open loop power control first and then closed loop power control.

As another example, if the specific field indicates band 1, it indicates that the power application information in the transmission power control information indicates that power indication 1 is available for band 1. As another example, if the specific domain indicates the uplink channel 1, it indicates that the power application information in the transmission power control information indicates that the power indication 1 is available for the uplink channel 1.
