Description

Communication method, device and system

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for communications.

Background

With the development of wireless communication technology, various new services are layered endlessly, and the resource requirements of different services are different, so that it is required that various services can use limited channel resources more efficiently in future wireless networks. In long term evolution systems (long term evolution, LTE) and in 5G new radio technology (NR) systems, the sounding reference signal (sounding reference signal, SRS) is an important uplink signal. After a User Equipment (UE) establishes a connection with a base station, the base station may allocate SRS resources to the UE and then estimate uplink channel quality through SRS transmitted by the UE. In particular, in a time division duplex system, based on reciprocity of uplink and downlink channels, the base station can also estimate downlink channel quality according to SRS transmitted by the UE, so as to perform downlink beam forming. Due to the time-varying characteristics of the wireless communication channel, if the transmission period of the SRS transmitted in the currently configured period or the SRS transmitted semi-statically is longer, the effect of channel estimation by the SRS is poorer, and thus the user and the system throughput rate are affected, but if the transmission period is shorter, the SRS resource is insufficient to be allocated to each user.

In the prior art, the available SRS resource range of the UE in each cell is limited, and when the base station allocates SRS resources to the UE in the cell, only the capability indication information reported when the user accesses and the current status of the base station resources are considered, and SRS resources which are not allocated in the available SRS resource range are allocated to the UE. This manner of SRS resource allocation only when a user accesses is poor in flexibility and utilization efficiency of SRS resource usage.

Disclosure of Invention

The technical problem to be solved by the embodiments of the present application is to provide a communication method, a communication device, and a network, so as to solve the problems of limited SRS resources, inflexible allocation, and poor utilization efficiency.

In a first aspect, an embodiment of the present application provides a communication method, where 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.

By the method, the terminal can send the indication information to the network equipment after the terminal is accessed to the network equipment, and inform the network equipment of the current demand of the network equipment for the SRS resources, so that the network equipment can dynamically and reasonably adjust the SRS resources allocated to the terminal, and the flexibility of SRS resource allocation and the utilization rate of the SRS resources are improved.

In one possible implementation, before the terminal sends the first indication information to the network device, the terminal further determines, based on the state information of the terminal, an SRS resource configuration desired by the terminal. Through the implementation manner, the terminal can send the first indication information to the network equipment according to the trigger of the state of the terminal after the terminal is accessed to the network equipment, so that the terminal can correctly indicate the SRS resource requirement of the terminal to the network equipment.

In one possible implementation manner, the state information of the terminal includes at least one of a temperature of the terminal reaching a preset temperature, an electric quantity of the terminal reaching a preset electric quantity, at least one antenna of the terminal being faulty, a service throughput rate of the terminal, or distance information of the terminal and a network device.

In one possible implementation, the terminal receives the second SRS resource configuration information from the network device before the terminal sends the first indication information to the network device. The terminal determines an SRS resource configuration desired by the terminal based on the state information of the terminal and the second SRS resource configuration information. Through the implementation manner, the terminal can determine the SRS resource configuration expected by the terminal in the initial SRS resource range allocated by the network equipment for the terminal according to the state information of the terminal. Therefore, not only the signaling overhead of the first indication information can be reduced, but also the current demand of the terminal for SRS resources fed back to the network equipment is more reasonable.

In one possible implementation, before the terminal receives the first SRS resource configuration information from the network device, the terminal may further receive an acknowledgement response from the network device, where the acknowledgement response is used to indicate that the network device successfully receives the first indication information. The terminal adjusts SRS transmission based on the SRS resource configuration desired by the terminal. By means of the implementation manner, the terminal can adjust the sending of the SRS according to the SRS resource configuration expected by the terminal under the condition that the network equipment is confirmed to receive the first indication information, so that the situation that the network equipment misconsiders the SRS sent by the terminal in adjustment as interference is reduced. That is, when the network device receives the first indication information, the network device performs SRS measurement according to the SRS resource configuration (i.e. the SRS resource configuration expected by the terminal) that is understood by both parties, so that the network device will not detect the signal at the position where the terminal transmits the SRS as an interference signal. Meanwhile, through the implementation manner, the exemplary beneficial effects also include that the terminal does not need to wait until the network equipment reallocates the terminal and sends the first SRS resource configuration information to the terminal based on the first indication information, and then adjusts the sending of the SRS. Especially when the first SRS resource configuration information is carried in higher layer signaling (e.g. radio resource control (radio resource control, RRC) message) and the acknowledgement response is carried in lower layer signaling (e.g. physical layer signaling), the terminal can adjust its SRS transmission faster.

In one possible implementation, after the terminal receives the first SRS resource configuration information from the network device, the terminal may adjust SRS transmission based on the first SRS resource configuration information. Through the implementation manner, exemplary beneficial effects include that the terminal can obtain more reasonable SRS resources from the network equipment. That is, the first SRS resource configuration information may cover the SRS resource configuration expected by the terminal according to which the terminal transmits the SRS before, so that the terminal may perform reasonable SRS transmission according to the first SRS resource configuration newly allocated to the terminal by the network device based on the first indication information.

In one possible implementation, the SRS resource configuration information is used to indicate at least one of: the periodicity of the SRS resources, the offset of the SRS resources, or the frequency hopping parameters of the SRS.

In one possible implementation, the offset of the SRS resource includes an offset between the SRS resource and a starting point in time of a period of the SRS resource.

In one possible implementation, the frequency hopping parameter of the SRS includes at least one of: full bandwidth for SRS measurements, number of hops required for full bandwidth SRS measurements, or bandwidth for each SRS measurement.

In a possible implementation manner, the first indication information is carried in user equipment auxiliary information or overheat protection information of the terminal.

In a second aspect, embodiments of the present application provide a communication method, including a network device receiving first indication information from a terminal, where the first indication information indicates an SRS resource configuration expected by the terminal. And the network equipment determines first SRS resource configuration information according to the first indication information and sends the first SRS resource configuration information to the terminal.

By the method, the flexibility and the utilization rate of SRS allocation can be improved, and for terminals with reduced demands, the network equipment can dynamically reduce the allocation of SRS resources to the terminals, so that the newly accessed terminals can obtain enough SRS resources, the cell throughput rate and the number of users are improved, and the efficiency of channel estimation by the network equipment is also improved.

In one possible implementation, the network device may also send the second SRS resource configuration information to the terminal before the network device receives the first indication information from the terminal.

In one possible implementation, after the network device receives the first indication information from the terminal, the network device sends a response to the terminal, where the response is used to indicate that the network device successfully receives the first indication information. The network device adjusts SRS measurements based on the SRS resource configuration desired by the terminal. By the implementation manner, exemplary beneficial effects include reducing the situation that the network device mistakes the SRS which is regulated to be transmitted by the terminal as interference. That is, when the network device receives the first indication information, the network device performs SRS measurement according to the SRS resource configuration (i.e. the SRS resource configuration expected by the terminal) that is understood by both parties, so that the network device will not detect the signal at the position where the terminal transmits the SRS as an interference signal. Meanwhile, through the implementation manner, the exemplary beneficial effects also include that the network equipment does not need to wait until the network equipment reallocates the terminal and sends the first SRS resource configuration information to the terminal based on the first indication information, and then adjusts SRS measurement. Especially when the first SRS resource configuration information is carried in higher layer signaling (e.g. radio resource control (radio resource control, RRC) message) and the acknowledgement response is carried in lower layer signaling (e.g. physical layer signaling), the network device can adjust its SRS measurement faster.

The following describes a communication method and apparatus according to an embodiment of the present invention in detail with reference to fig. 2 to 5.

Referring to fig. 2, fig. 2 is a flow chart of a communication method 100 according to an embodiment of the present application. The method comprises the following steps:

s201: the terminal sends first indication information to the network equipment.

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

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

Wherein the offset of the SRS resource may include an offset between the SRS resource and a starting point in time of a period of the SRS resource.

Illustratively, the periodicity of the SRS resource and the time unit of the offset of the SRS resource may or may not be the same. The time unit may include an orthogonal frequency division multiplexing symbol (orthogonal frequency division multiplexing symbol, OFDM symbol), a slot (slot), a subframe (subframe), or a frame (frame), etc.

Taking the definition of the periodicity of SRS resources and the offset of SRS resources in the third generation partnership project (3rd Generation Partnership Project,3GPP) ts38.331v16.6.0 (2021-09) as an example, the periodicity of SRS resources and the offset of SRS resources include periodic and offset. Wherein periodic and offset is used to indicate the periodicity of the SRS resource and the offset of the SRS resource.

The frequency hopping parameter of the SRS may include at least one of: the number of hops required for the full-bandwidth SRS measurement (e.g., the total bandwidth required for the SRS measurement or SRS transmission), or the bandwidth of each SRS measurement (e.g., the product of the bandwidth of each SRS measurement and the number of hops required for the full-bandwidth SRS measurement is equal to the total bandwidth of the SRS measurement), the pattern of SRS hopping (pattern) (e.g., the pattern may indicate that the SRS measurement or transmission is performed in a frequency-first-to-high order, or in a frequency-first-to-first-high-to-low order, etc.), and the pattern may indicate that the UE selects a timing of a different frequency band that is available for transmitting SRS, for example.

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

Illustratively, the full bandwidth of the SRS measurement may or may not be the same as the frequency domain units of the bandwidth of each SRS measurement. The frequency domain unit may include Resource Blocks (RBs), hertz (HZ), physical resource blocks (physical resource block, PRBs), and the like.

In the frequency hopping mode of SRS, the terminal may implement full-bandwidth SRS measurement over the full bandwidth of SRS measurement within one SRS measurement period (e.g., a period that may be equal to several SRS resources).

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

In one possible implementation, the terminal may determine an SRS resource configuration desired by the terminal based on state information of the terminal.

Wherein the state information of the terminal includes at least one of: whether the temperature of the terminal reaches a preset temperature (e.g., whether the terminal is in an overheated state), whether the electric quantity of the terminal reaches a preset electric quantity (or whether the terminal needs to enter an energy-saving mode), whether at least one antenna of the terminal is faulty (that is, the terminal is limited in capability), the service throughput of the terminal (e.g., whether a large packet service or a small packet service, a large flow service or a small flow service, a high speed service or a low speed service is being processed), or the distance information of the terminal from the network device (e.g., whether the terminal is at a far point or a near point).

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

The electric quantity of the terminal reaches a preset electric quantity; the preset temperature may be one value or may be a plurality of values, and the adjustment of the corresponding SRS resource may be divided into a plurality of levels. For example, when the terminal power is reduced to 20%, the allocation of SRS resources is reduced, and when the terminal power is reduced to 5%, the allocation of SRS resources can be further reduced. When the power increases, the adjustment of SRS resources can be divided into a plurality of levels as well.

At least one antenna of the terminal fails. The adjustment of the corresponding SRS resources may be divided into multiple levels according to the number of failed antennas. For example, when 1 failed antenna is used, the SRS resource allocation is reduced, and when 2 failed antennas are used, the SRS resource allocation can be further reduced. When the failed antenna returns to normal, the SRS resource may be adjusted into a plurality of levels according to the number of antennas that return to normal.

For example, when the terminal determines not to transmit the SRS based on the state information of the terminal, the first indication information may include information indicating that the terminal desires not to transmit the SRS. Alternatively, 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 expects not to send SRS resources according to the infinite SRS resource period value expected by the terminal.

S202: the network device sends the 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 allocation information according to the first indication information, and send the first SRS resource allocation information to the terminal.

For example, the network device may reallocate SRS resources for the terminal according to the SRS resource configuration expected by the terminal and the capability indication information reported before the terminal indicated by the first indication information, the current SRS resource allocation status of the network device, the number of terminals currently managed by the network device, and the like, and send the first SRS resource configuration information indicating the new SRS resource allocation to the terminal.

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

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

s203: the network device sends the second SRS resource configuration information to the terminal.

The second SRS resource configuration information may be, for example, an initial SRS resource allocation for the terminal determined by the network device based on terminal capability indication information sent to the network device when the terminal accesses the network device, and a current resource status of the network device (e.g., SRS resource allocation).

The terminal in S201 may determine the SRS resource configuration desired by the terminal based on the state information of the terminal and the second SRS resource configuration information.

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

In one aspect, the period of the SRS resource indicated by the second SRS resource configuration is assumed to be 20 slots, and the offset of the SRS resource is assumed to be 0 slots. When the terminal determines that the period of the SRS needs to be changed based on the state information of the terminal (if the terminal needs to enter the energy-saving mode), the terminal may determine the period of the SRS resource indicated by the SRS resource configuration expected by the terminal as N times of 20 slots, where N may be a fraction or an integer.

Assume that a terminal determines a period of SRS resources indicated by an SRS resource configuration desired by the terminal as 40 slots. One possible implementation is that the period of SRS resources is included in the SRS resource configuration desired by the terminal and the period value is set to 40. Another possible implementation manner is that the first value is included in the SRS resource configuration expected by the terminal and is set to 2, so that the network device knows that the period of the SRS resource expected by the terminal is equal to 2 times (i.e. 40 slots) the period of the SRS resource indicated by the second SRS resource configuration information, which can also reduce the signaling overhead of the first indication information.

Further, since there should be two resource time domain positions available for transmitting SRS in the expected period of 40 slots according to the indication of the second SRS resource configuration information, for example, the first slot and 21 st slot may be.

At this time, the terminal may set an offset of the SRS resource indicated by the SRS resource configuration desired by the terminal to 0 slots. One possible implementation is that the offset of the SRS resource is included in the SRS resource configuration desired by the terminal and the offset value is set to 0. Another possible implementation manner is that the SRS resource configuration expected by the terminal includes a second value and the second value is set to 1, so that the network device knows that the terminal selects the first resource time domain position (i.e. the 1 st slot) for transmitting the SRS of the indication of the second SRS resource configuration information, and in this way, signaling overhead of the first indication information can be reduced. Alternatively, the terminal may set the offset of the SRS resource indicated by the SRS resource configuration desired by the terminal to 20 slots. One possible implementation is that the offset of the SRS resource is included in the SRS resource configuration desired by the terminal and the offset value is set to 20. Another possible implementation manner is that the SRS resource configuration expected by the terminal includes a second value and the second value is set to 2, so that the network device knows that the terminal selects the second resource time domain location (i.e. the 2 nd slot) for transmitting the SRS of the indication of the second SRS resource configuration information, and in this way, signaling overhead of the first indication information can be reduced.

On the other hand, assume that the number of hops required for the full-bandwidth SRS measurement indicated by the second SRS resource configuration is 4 or 24 RBs per bandwidth of the SRS measurement. When the terminal determines that the frequency hopping of the SRS needs to be changed based on the state information of the terminal (if the terminal needs to enter the power saving mode), the terminal may determine the number of frequency hops required for the full-bandwidth SRS measurement indicated by the SRS resource configuration expected by the terminal to be M times of 4, or may determine the bandwidth of each SRS measurement indicated by the SRS resource configuration expected by the terminal to be M times of 24 RBs, where M may be a fraction or an integer.

In method 100, the operating state of a terminal may be dynamically changed after the terminal accesses a network device. This causes the terminal's demand for SRS resources to change as well. For example, as the working duration of the terminal continues, the power of the terminal may decrease gradually, when the power is reduced to a certain power threshold, the terminal may enter an energy saving mode, at this time, the capability of the terminal to meet the SRS resource allocation may also decrease correspondingly, and when the terminal charges, the power is restored to above the power threshold, at this time, the requirement of the terminal for the SRS resource may also increase correspondingly. Therefore, the network device may be informed of the current need for SRS resources by the first indication information. By the method, the terminal can send the indication information to the network equipment after the terminal is accessed to the network equipment, and inform the network equipment of the current demand of the network equipment for the SRS resources, so that the network equipment can dynamically and reasonably adjust the SRS resources allocated to the terminal, and the flexibility of SRS resource allocation and the utilization rate of the SRS resources are improved.

Referring to fig. 3, a flow chart of another communication method 200 according to an embodiment of the present application is shown; the method comprises the following steps:

s301: the network device sends the second SRS resource configuration information to the terminal.

S302: the terminal sends first indication information to the network equipment.

The operation may refer to operation S201.

S303: the network device sends a response to the terminal.

After the network device receives the first indication information from the terminal, the network device transmits a response to the terminal. The response is used for indicating that the network equipment successfully receives the first indication information, or the response is used for indicating that the network equipment agrees to accept the SRS resource configuration expected by the terminal indicated by the first indication information.

The acknowledgement response may be, for example, an Acknowledgement (ACK). The reply response may be carried in a physical layer message, a medium access control element (media access control control element, MAC CE).

S304: the terminal adjusts SRS transmission.

After the terminal receives the response from the network device, it may be determined that the network device has successfully received the first indication information, or the network device has agreed to accept the SRS resource configuration expected by the terminal indicated by the first indication information.

The terminal may adjust SRS transmission according to the SRS resource configuration desired by the terminal.

S305: the network device adjusts SRS measurements.

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

Exemplary benefits include reducing instances where the network device misinterprets the SRS that the terminal adjusts to transmit as interference through the response. That is, when the network device receives the first indication information, the network device performs SRS measurement according to the SRS resource configuration (i.e. the SRS resource configuration expected by the terminal) that is understood by both parties, so that the network device will not detect the signal at the position where the terminal transmits the SRS as an interference signal.

Meanwhile, through the embodiment of the application, the exemplary beneficial effects also include that the terminal does not need to wait until the network equipment reallocates the terminal 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 a higher layer signaling (such as a radio resource control (radio resource control, RRC) message) and the response is carried in an underlying layer signaling (such as a physical layer signaling), the terminal may adjust its SRS transmission faster, and the network device may also adjust its SRS measurement faster.

Optionally, the method 200 may further include S306:

s306: the network device sends the first SRS resource configuration information to the terminal.

Through S306, exemplary benefits include that the network device can reconfigure SRS resources for the terminal at an appropriate time (e.g., the SRS resource remaining amount or the network device processing capability remaining amount reaches a certain threshold). The terminal may obtain more reasonable SRS resources from the network device. That is, the first SRS resource configuration information may cover the SRS resource configuration expected by the terminal according to which the terminal transmits the SRS before, so that the terminal may perform reasonable SRS transmission according to the first SRS resource configuration newly allocated to the terminal by the network device based on the first indication information.

In addition, by the method 200, the allocation of the SRS resources can be dynamically reduced for the terminal with reduced capability or requirement, so that the user capacity of the network equipment can be expanded, the newly accessed terminal can obtain enough SRS resources, and the flexibility and the utilization rate of SRS allocation are improved.
