Description

A communication method, device and system

This application claims the priority of the Chinese patent application with the application number 202111278091.1 and the application title "a method, device and system for communication" submitted to the China Patent Office on October 30, 2021, the entire contents of which are incorporated herein by reference. Applying.

technical field

The present application relates to the technical field of communication, and in particular to a communication method, device and system.

Background technique

With the development of wireless communication technology, various new services emerge one after another, and different services have different resource requirements. This requires that various services in future wireless networks should be able to use limited channel resources more efficiently. In the long term evolution system (long term evolution, LTE) and 5G new radio technology (new radio, NR) system, the sounding reference signal (sounding reference signal, SRS) is a very important uplink signal. After the user equipment (user equipment, UE) establishes a connection with the base station, the base station can allocate SRS resources for the UE, and then estimate the uplink channel quality through the SRS sent by the UE. In particular, in a time division duplex system, based on the reciprocity of the uplink and downlink channels, the base station can also estimate the quality of the downlink channel according to the SRS sent by the UE, and then perform downlink beamforming. Due to the time-varying characteristics of the wireless communication channel, if the currently configured SRS sent periodically or the SRS sent semi-statically has a longer sending period, the effect of using SRS for channel estimation will be worse, which will affect the user and system throughput. The shorter the cycle, the SRS resources are not enough to be allocated to each user.

In the existing technology, the range of SRS resources available to UEs in each cell is limited. When the base station allocates SRS resources for UEs in the cell, it often only considers the capability indication information reported by users when they access and the current status of base station resources. , allocating unallocated SRS resources within the range of available SRS resources to the UE. This way of allocating SRS resources only when users access is poor in terms of flexibility and utilization efficiency of SRS resources.

Contents of the invention

In a first aspect, an embodiment of the present application provides a communication method, wherein a terminal sends first indication information to a network device, where the first indication information indicates an SRS resource configuration expected by the terminal. The terminal receives first SRS resource configuration information from the network device.

Through this method, the exemplary beneficial effects include that after the terminal accesses the network device, the terminal can send indication information to the network device to inform the network device of its current demand for SRS resources, so that the network device can dynamically and reasonably adjust the resources allocated to the terminal. SRS resources, thereby improving the flexibility of SRS resource allocation and the utilization rate of SRS resources.

In a possible implementation manner, before the terminal sends the first indication information to the network device, the terminal also determines the SRS resource configuration expected by the terminal based on the state information of the terminal. Through this implementation, exemplary beneficial effects include that after the terminal accesses the network device, it can send the first indication information to the network device according to the trigger of its own state, so that the terminal can correctly indicate its own SRS resource requirements to the network device .

This can not only reduce the signaling overhead of the first indication information, but also make the terminal's current demand for SRS resources fed back to the network device more reasonable.

In a possible implementation manner, before the terminal receives the first SRS resource configuration information from the network device, the terminal may also receive an acknowledgment response from the network device, where the acknowledgment response is used to indicate that the network device has successfully received The first indication information. The terminal adjusts the sending of the SRS based on the SRS resource configuration expected by the terminal. Through this implementation, exemplary beneficial effects include that the terminal can adjust the SRS transmission according to the SRS resource configuration expected by the terminal under the condition that the network device has received the first indication information, so as to reduce the network device's need to send the terminal Adjusted for cases where the sent SRS is mistaken for interference. That is to say, after the network device receives the first indication information, it will perform SRS measurement according to the SRS resource configuration (that is, the SRS resource configuration expected by the terminal) understood by both parties, so that the network device will not send the terminal The signal at the location of the SRS is detected as an interfering signal. At the same time, through this implementation, exemplary beneficial effects include that the terminal does not need to wait until the network device re-allocates and sends the first SRS resource configuration information to the terminal based on the above-mentioned first indication information, and then adjusts the sending of the SRS . Especially when the first SRS resource configuration information is carried in high-level signaling (such as radio resource control (radio resource control, RRC) message), when the response response is carried in bottom signaling (such as physical layer signaling), the terminal You can adjust your own SRS sending much faster.

In a possible implementation manner, after the terminal receives the first SRS resource configuration information from the network device, the terminal may adjust SRS sending based on the first SRS resource configuration information. Through this implementation, exemplary beneficial effects include that the terminal can obtain more reasonable SRS resources from the network device. That is to say, the first SRS resource configuration information can overwrite the terminal's expected SRS resource configuration according to which the terminal sends the SRS before, so that the terminal can use the first SRS resource configuration newly allocated to the terminal by the network device based on the above-mentioned first indication information. The SRS resource is configured, and the SRS is sent reasonably.

The network device adjusts the SRS measurement based on the SRS resource configuration expected by the terminal. Through this implementation manner, exemplary beneficial effects include reducing the situation that the network device mistakenly regards the SRS adjusted and sent by the terminal as interference. That is to say, after the network device receives the first indication information, it will perform SRS measurement according to the SRS resource configuration (that is, the SRS resource configuration expected by the terminal) understood by both parties, so that the network device will not send the terminal The signal at the location of the SRS is detected as an interfering signal. At the same time, through this implementation, the exemplary beneficial effect also includes that the network device does not need to wait until it re-allocates and sends the first SRS resource configuration information to the terminal based on the above-mentioned first indication information, and then adjusts the SRS. Measurement. Especially when the first SRS resource configuration information is carried in high-level signaling (such as radio resource control (radio resource control, RRC) message), when the response response is carried in bottom signaling (such as physical layer signaling), the network Devices can adjust their own SRS measurements more quickly.

The communication method and device of the embodiment of the present invention will be described in detail below with reference to FIGS. 2-5 .

Please refer to FIG. 2 . FIG. 2 is a schematic flowchart of a communication method 100 provided in an embodiment of the present application. Including the following steps:

S201: The terminal sends first indication information to the network device.

Wherein, the first indication information indicates the SRS resource configuration expected by the terminal.

In this application, the SRS resource configuration information may be used to indicate at least one of the following: a period (periodicity) of the SRS resource, an offset (Offset) of the SRS resource, or a parameter of SRS frequency hopping (freqHopping).

Wherein, the offset of the SRS resource may include an offset between the SRS resource and the start time point of the period of the SRS resource.

Exemplarily, the period of the SRS resource and the time unit of the offset of the SRS resource may be the same or different. The time unit may include an orthogonal frequency division multiplexing symbol (orthogonal frequency division multiplexing symbol, OFDM symbol), a time slot (slot), a subframe (subframe), or a frame (frame).

Taking the definition of the cycle of SRS resources and the offset of SRS resources in the 3rd Generation Partnership Project (3GPP) TS38.331v16.6.0 (2021-09) as an example, the cycle of SRS resources and the offset of SRS resources Offset includes periodicityAndOffset. The periodicityAndOffset is used to indicate the period of the SRS resource and the offset of the SRS resource.

The frequency hopping parameters of the SRS may include at least one of the following: the full bandwidth of the SRS measurement (for example, the entire bandwidth required for SRS measurement or SRS transmission), the number of frequency hops required for the full bandwidth SRS measurement (for example, in the SRS measurement The number of times to complete all SRS measurements or SRS transmissions in the full bandwidth), or the bandwidth of each SRS measurement (for example, the product of the bandwidth of each SRS measurement and the number of frequency hops required for the full bandwidth SRS measurement is equal to the full bandwidth of the SRS measurement) , the pattern (pattern) of SRS frequency hopping (for example, the pattern can indicate that SRS measurement or transmission is performed according to the frequency from low to high, or SRS measurement or transmission is performed according to the order of frequency first low then high and then low. For another example, the pattern The UE may be instructed to select the timing of a different frequency band that can be used to transmit the SRS).

Take the definition of SRS frequency hopping parameters in 3GPP TS38.331 v16.6.0 (2021-09) as an example, the SRS frequency hopping parameters include c-SRS, b-SRS, or b-hop. Wherein c-SRS is used to indicate the full bandwidth of SRS measurement. The c-SRS and b-SRS are used to jointly indicate the bandwidth of each SRS measurement, and/or, the number of frequency hopping required for the full bandwidth SRS measurement. b-hop is used to indicate the pattern of SRS frequency hopping.

Exemplarily, the frequency domain units of the full bandwidth of the SRS measurement and the bandwidth of each SRS measurement may be the same or different. The frequency domain unit may include resource block (resource block, RB), hertz (hertz, HZ), physical resource block (physical resource block, PRB), etc.

Exemplarily, in the SRS frequency hopping mode, the terminal can implement full-bandwidth SRS measurement on the full-bandwidth of SRS measurement within one SRS measurement cycle (for example, a cycle equal to several SRS resources).

Optionally, the first indication information may be carried in user equipment assistance information (UE Assistance Information) or overheating protection information (Overheating Assistance) of the terminal.

In a possible implementation manner, the terminal may determine the SRS resource configuration expected by the terminal based on the state information of the terminal.

Wherein, the status information of the terminal includes at least one of the following: whether the temperature of the terminal reaches a preset temperature (for example, whether it is in an overheated state), whether the power of the terminal reaches a preset power (or in other words, whether it needs to enter an energy-saving mode), At least one antenna of the terminal fails (that is, the terminal capability is limited), and the service throughput rate of the terminal (for example, whether it is processing large or small packet services, large or small flow services, high-speed services or low-speed services) ), or distance information between the terminal and the network device (for example, whether it is at a far point or a near point).

The temperature of the terminal reaches a preset temperature; here, the preset temperature can be one value or multiple values, and the adjustment of corresponding SRS resources can also be divided into multiple levels. For example, when the temperature of the terminal reaches 40 degrees, the allocation of SRS resources is reduced, and when the temperature of the terminal reaches 60 degrees, the allocation of SRS resources may be further reduced. When the temperature drops, the adjustment of SRS resources can also be divided into multiple levels.

The power of the terminal reaches the preset power; here the preset temperature can be one value or multiple values, and the adjustment of corresponding SRS resources can also be divided into multiple levels. For example, when the power of the terminal is reduced to 20%, the allocation of SRS resources is reduced, and when it is reduced to 5%, the allocation of SRS resources can be further reduced. When the power level increases, the adjustment of SRS resources can also be divided into multiple levels.

At least one antenna of the terminal has failed. Here, the adjustment of the corresponding SRS resources can be divided into multiple levels according to the number of failed antennas. For example, when there is one failed antenna, the allocation of SRS resources is reduced, and when there are two failed antennas, the allocation of SRS resources may be further reduced. When the failed antenna returns to normal, the adjustment of the SRS resources may also be divided into multiple levels according to the number of antennas that return to normal.

Exemplarily, when the terminal determines not to send the SRS based on the state information of the terminal, the first indication information may include information indicating that the terminal expects not to send the SRS. Optionally, the terminal may set the period (periodicity) of the SRS resource indicated in the first indication information to infinity. In this way, the network device can determine that the terminal does not expect to send SRS resources according to the infinite SRS resource period value expected by the terminal.

S202: The network device sends first SRS resource configuration information to the terminal.

After receiving the first indication information from the terminal, the network device may determine first SRS resource configuration information according to the first indication information, and send the first SRS resource configuration information to the terminal.

Exemplarily, the network device may, according to the terminal's expected SRS resource configuration indicated by the first indication information, the capability indication information previously reported by the terminal, the current SRS resource allocation status of the network device, and the terminal currently managed by the network device number, etc., re-allocate SRS resources for the terminal, and send the first SRS resource configuration information indicating the new SRS resource allocation to the terminal.

Exemplarily, the first SRS resource configuration information may be carried in a radio resource control reconfiguration (radio resource control reconfiguration, RRC reconfig) message.

Optionally, before the terminal sends the first indication information to the network device, that is, before operation S201, the method 100 may also include S203:

S203: The network device sends second SRS resource configuration information to the terminal.

Exemplarily, the second SRS resource configuration information may be determined by the network device based on the terminal capability indication information sent to the network device when the terminal accesses the network device, and the resource status (such as SRS resource allocation) of the network device. The terminal's initial SRS resource allocation.

At this time, the terminal in S201 may determine the SRS resource configuration expected by the terminal based on the status information of the terminal and the second SRS resource configuration information.

Exemplarily, a time slot (slot) is used as a time unit, and of course the time unit may also be a subframe (subframe), a frame (frame), or an orthogonal frequency division multiplexing symbol (orthogonal frequency division multiplexing symbol, OFDM symbol). The period of the SRS resource and the time unit of the offset of the SRS resource may also be different.

On the one hand, it is assumed that the period of the SRS resource indicated by the second SRS resource configuration is 20 slots, and the offset of the SRS resource is 0 slot. When the terminal determines that the period of the SRS needs to be changed based on the state information of the terminal (for example, it needs to enter the energy-saving mode), the terminal can determine the period of the SRS resource indicated by the SRS resource configuration expected by the terminal as a period of 20 slots N times, N can take a fraction or an integer.

Assume that the terminal determines the period of the SRS resource indicated by the terminal's desired SRS resource configuration as 40 slots. A possible implementation manner is that the SRS resource configuration desired by the terminal includes the period of the SRS resource and the period value is set to 40. Another possible implementation is that the terminal's desired SRS resource configuration includes a first value and the first value is set to 2, so that the network device knows that the period of the terminal's desired SRS resource is equal to that of the second SRS resource configuration information. The period of the indicated SRS resource is doubled (that is, 40 slots). In this way, the signaling overhead of the first indication information can also be reduced.

Further, because according to the indication of the second SRS resource configuration information, within the expected period of 40 slots, there should be two resource time domain positions that can be used to send SRS, for example, the first slot and the second slot 21 slots.

At this time, the terminal may set the offset of the SRS resource indicated by the SRS resource configuration expected by the terminal as 0 slots. A possible implementation manner is that the SRS resource configuration expected by the terminal includes the offset of the SRS resource and the offset value is set to 0. Another possible implementation is that the terminal's desired SRS resource configuration includes a second value and the second value is set to 1, so that the network device knows that the terminal has selected the first one indicated by the second SRS resource configuration information. The time-domain position of the resource used to send the SRS (that is, the first slot), in this way, can also reduce the signaling overhead of the first indication information. Alternatively, the terminal may also set the SRS resource offset indicated by the terminal's desired SRS resource configuration as 20 slots. A possible implementation manner is that the SRS resource configuration desired by the terminal includes an offset of the SRS resource and the offset value is set to 20. Another possible implementation is that the terminal's expected SRS resource configuration includes a second value and the second value is set to 2, so that the network device knows that the terminal has selected the second one indicated by the second SRS resource configuration information. The time-domain position of the resource used to send the SRS (that is, the second slot), in this way, can also reduce the signaling overhead of the first indication information.

On the other hand, it is assumed that the number of frequency hopping required for the full-bandwidth SRS measurement indicated by the second SRS resource configuration is 4 or the bandwidth of each SRS measurement is 24 RBs. When the terminal determines that the frequency hopping of SRS needs to be changed based on the state information of the terminal (such as needing to enter the energy-saving mode), the terminal can configure the SRS resources expected by the terminal to indicate the frequency hopping required for the full-bandwidth SRS measurement The number of times is determined to be M times of 4, or the bandwidth of each SRS measurement indicated by the terminal's desired SRS resource configuration may be determined to be M times of 24 RBs, where M may be a fraction or an integer.

In method 100, after the terminal accesses the network device, the working state of the terminal may change dynamically. In this way, the requirements of the terminal for SRS resources will also change. For example, as the working hours of the terminal continue, the power of the terminal will gradually decrease. When the power reaches a certain power threshold, the terminal can enter the energy-saving mode. At this time, the terminal's ability to satisfy the SRS resource configuration may also decrease accordingly. When the terminal is charging and the battery power returns to above the power threshold, the terminal's demand for SRS resources may increase accordingly. Therefore, the network device may be notified of the terminal's current requirement for SRS resources through the first indication information. Through this method, the exemplary beneficial effects include that after the terminal accesses the network device, the terminal can send indication information to the network device to inform the network device of its current demand for SRS resources, so that the network device can dynamically and reasonably adjust the resources allocated to the terminal. SRS resources, thereby improving the flexibility of SRS resource allocation and the utilization rate of SRS resources.

Please refer to FIG. 3 , which is a schematic flowchart of another communication method 200 provided in the embodiment of the present application; it includes the following steps:

S301: The network device sends second SRS resource configuration information to the terminal.

S302: The terminal sends first indication information to the network device.

For this operation, refer to operation S201.

S303: The network device sends an answer response to the terminal.

After the network device receives the first indication information from the terminal, the network device sends an answer response to the terminal. Wherein, the response response is used to indicate that the network device has successfully received the first indication information, or the response response is used to indicate that the network device agrees to accept the SRS resource configuration expected by the terminal indicated by the first indication information.

Exemplarily, the acknowledgment response may be an acknowledgment (acknowledge, ACK). The response response may be carried in a physical layer message, a media access control control element (media access control control element, MAC CE).

S304: The terminal adjusts the SRS transmission.

After the terminal responds according to the received response from the network device, it may determine that the network device has successfully received the first indication information, or the network device has agreed to accept the terminal's desired SRS resource configuration indicated by the first indication information.

The terminal can adjust the sending of the SRS according to the SRS resource configuration expected by the terminal.

S305: The network device adjusts the SRS measurement.

After the network device sends the response to the terminal, it can adjust the SRS measurement based on the SRS resource configuration expected by the terminal.

Through the acknowledgment response, exemplary beneficial effects include reducing the situation that the network device may mistake the SRS adjusted to be sent by the terminal as interference. That is to say, after the network device receives the first indication information, it will perform SRS measurement according to the SRS resource configuration (that is, the SRS resource configuration expected by the terminal) understood by both parties, so that the network device will not send the terminal The signal at the location of the SRS is detected as an interfering signal.

At the same time, through the embodiment of the present application, exemplary beneficial effects also include that the terminal does not need to wait until the network device reallocates and sends the first SRS resource configuration information to the terminal based on the first indication information, and then adjusts the SRS. Measurement. Especially when the first SRS resource configuration information is carried in high-level signaling (such as radio resource control (radio resource control, RRC) message), when the response response is carried in bottom signaling (such as physical layer signaling), the terminal It can adjust its own SRS transmission faster, and the network device can also adjust its own SRS measurement faster.

Optionally, method 200 may also include S306:

S306: The network device sends the first SRS resource configuration information to the terminal.

Through S306, exemplary beneficial effects include that the network device can reconfigure SRS resources for the terminal at an appropriate time (for example, the remaining amount of SRS resources or the remaining amount of processing capability of the network device reaches a certain threshold). The terminal can obtain more reasonable SRS resources from the network device. That is to say, the first SRS resource configuration information can overwrite the terminal's expected SRS resource configuration according to which the terminal sends the SRS before, so that the terminal can use the first SRS resource configuration newly allocated to the terminal by the network device based on the above-mentioned first indication information. The SRS resource is configured, and the SRS is sent reasonably.

In addition, through the above method 200, it is possible to dynamically reduce the allocation of SRS resources for terminals with reduced capabilities or needs, thereby expanding the user capacity of network devices, facilitating new access terminals to obtain sufficient SRS resources, and improving SRS allocation. flexibility and utilization.
