Description

Method and equipment for reporting and receiving reference signal

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method and a device for reporting and receiving a reference signal.

Background

At present, the fifth generation mobile communication technology is gradually mature, but the spectrum resources are increasingly in short supply in the current environment. In order to meet the requirements of the fifth generation mobile communication systems, the high band spectrum resources will be used more. Meanwhile, in order to ensure the coverage, an analog beam forming technology is adopted, so that the terminal equipment and the network side equipment select the optimal beam for communication. The high-frequency band spectrum resource is rich, but the radio propagation anti-attenuation capability is weak, and a serious blocking phenomenon exists, so that the signal can be interrupted by walls, trees and people moving around, and continuous coverage is difficult to realize. Therefore, when the terminal device judges that the quality of the communication link of the current beam for communicating with the network side device is poor, the terminal device sends a beam recovery request to the network side device, and meanwhile, the terminal device reports other alternative beams with good quality to the network side device to avoid communication interruption.

In the prior art, a terminal device sends a beam recovery request to a network side device through a dedicated PRACH (Physical Random Access Channel) resource. Since the PRACH resources are divided into a plurality of groups, and there is a correspondence between different resource groups, the preamble used, and the reference signal in the network side device, when the terminal device sends a beam recovery request to the network side device through the PRACH resources, the network side device may determine corresponding beam information according to the PRACH resources and the preamble. However, the terminal device can only send a beam recovery request on one PRACH resource group each time, and only one reference signal can be reported each time, so that the network side device can only recover through the beam corresponding to the reference signal reported by the terminal device when performing beam recovery, and the success rate of recovery is low; if the failure occurs, the terminal equipment needs to report again, repeat the operation, waste time and reduce the working efficiency.

In summary, in the prior art, when communication is interrupted, the terminal device can report only one reference signal to the network side device through the PRACH, so that the success rate of beam recovery is low, and the time delay is long.

Disclosure of Invention

The invention provides a method and equipment for reporting and receiving a reference signal, which are used for solving the problems of low success rate and large time delay of terminal equipment for beam recovery by using a PRACH (physical random access channel) when communication interruption occurs in the prior art.

In a first aspect, an embodiment of the present invention provides a method for reporting a reference signal, where the method includes:

the terminal equipment receives the number of the reported reference signals configured by the network side equipment;

the terminal device reports a reference signal in at least one candidate beam reference signal set to the network side device through a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH).

In the method, the terminal equipment receives the number of the reported reference signals configured by the network side equipment, and reports the reference signals in at least one alternative beam reference signal set to the network side equipment through a PUCCH or PUSCH after determining the number of the reference signals needing to be reported; because the terminal equipment can report the reference signals in the alternative beam reference signal set corresponding to the number of the configured reference signals to the network side equipment at one time through the PUCCH or PUSCH, and because the terminal equipment reports a plurality of reference signals, beam recovery is carried out between the terminal equipment and the network side equipment on the beams corresponding to the plurality of reference signals, the success rate of normal communication of beam recovery is improved, and the time delay is reduced.

In a possible implementation manner, the format of the reference signal in the candidate beam reference signal set reported by the terminal device includes a reference signal index value and a reference signal received power.

In a possible implementation manner, if the number of reported reference signals configured by the network side device and received by the terminal device is equal to 1, the receiving power value of the reference signal in the candidate beam reference signal set is represented by X bit; or

If the number of the reported reference signals received by the terminal equipment and configured by the network side equipment is greater than 1, the terminal equipment represents the receiving power value of the reference signal in the alternative beam reference signal set corresponding to the maximum receiving power by X bit, and represents the receiving power of the reference signal in the other alternative beam reference signal sets by Y bit;

According to the method, the reference signals in the alternative beam reference signal set are reported by using the format in the existing standard, so that the network side equipment can conveniently detect and identify, the beam corresponding to the received reference signal is determined, and the working efficiency is improved.

In a possible implementation manner, the RSRP (Reference Signal Receiving Power) value of at least one Reference Signal in the Reference signals in the candidate beam Reference Signal set reported by the terminal device is the first special state value.

According to the method, the first special state value is set between the terminal equipment and the network side equipment, so that when the terminal equipment sends the reference signal to the network side equipment, the network side equipment can determine the beam corresponding to the reference signal reported by the terminal equipment as the alternative beam according to the first special state value and communicate on the alternative beam, the beam with communication interruption before use is not used for communication, and the success rate of normal communication of the beam recovery can be improved.

In a possible implementation manner, if the number of the reference signals in the reported candidate beam reference signal set is smaller than the number of the reported reference signals configured by the network side, and all the reference signals reported by the terminal device to the network side device through the PUCCH or the PUSCH are reference signals in the candidate beam reference signal set, the remaining bit fields except the bit field of the reference signals in the reported candidate beam reference signal set are the second special state value.

According to the method, the terminal equipment fills the bit fields except the reference signal bit field in the reported alternative beam reference signal set by adopting the second special state value, so that the terminal equipment can normally report the reference signal to the network side equipment, and after the network side equipment receives the reference signal reported by the terminal equipment, the position filled by adopting the second special state value is determined to be meaningless, further the reference signals in the rest alternative beam reference signal set are detected, communication is carried out on a plurality of alternative beams, communication is not carried out on the beams with communication interruption before use, and the success rate of normal communication of beam recovery can be improved.

In a possible implementation manner, if the number of the Reference signals in the reported candidate beam Reference Signal set is smaller than the number of the reported Reference signals configured on the network side, and the Reference Signal reported by the terminal device to the network side device through the PUCCH or the PUSCH is a combination of the Reference Signal in the candidate beam Reference Signal set and L1-RSRP reporting, L1-RSRP (Layer One-Reference Signal Receiving Power) reporting uses an existing manner of mapping the received Power of the Reference Signal to a corresponding bit.

According to the method, the terminal equipment sends the plurality of reference signals to the network side equipment, so that the network side equipment determines the corresponding plurality of beams according to the reference signals and communicates on the plurality of beams, and the success rate of beam recovery is improved.

According to the method, the terminal equipment fills the bit fields except the reference signal bit field in the reported alternative beam reference signal set by using the second special state value, so that the terminal equipment can normally report the reference signal to the network side equipment, and after the network side equipment receives the reference signal reported by the terminal equipment, the position filled by using the second special state value is meaningless, and then the reference signals in the remaining alternative beam reference signal set are detected and communicated on a plurality of alternative beams, and meanwhile, the communication can be carried out on the previously used beams, so that the success rate of the beam recovery for carrying out normal communication can be improved.

In a second aspect, an embodiment of the present invention provides another method for reporting a reference signal, where the method includes:

the network side equipment configures the number of reported reference signals for the terminal equipment;

and the network side equipment receives the reference signals in the alternative beam reference signal set reported by the terminal equipment through a PUCCH or PUSCH.

According to the method, the network side equipment configures the number of the reported reference signals for the terminal equipment, so that the terminal equipment can report the number of the corresponding reference signals according to the quality of the received reference signals, the network side equipment receives the reference signals in the alternative beam reference signal set reported by the terminal equipment through the PUCCH or PUSCH, so that the network side equipment can search the corresponding alternative beam according to the reference signals in the alternative beam reference signal set reported by the terminal equipment, and further switch to the alternative beam for communication, and because a plurality of reference signals are received, the communication can be continued on the plurality of alternative beams, the success rate of beam recovery is improved, and the time delay is reduced.

In one possible implementation manner, the format of the reference signal in the candidate beam reference signal set received by the network side device includes a reference signal index value and a reference signal received power.

In a possible implementation manner, if the number of the reference signals configured and reported by the network side device for the terminal device is equal to 1, the receiving power value of the reference signal in the received candidate beam reference signal set is represented by X bit;

if the number of the reference signals configured and reported by the network side equipment for the terminal equipment is greater than 1, the receiving power value of the reference signal in the alternative beam reference signal set corresponding to the received maximum receiving power is represented by X bit, and the receiving power of the reference signal in the rest alternative beam reference signal sets is represented by Y bit;

wherein X is a positive integer and Y is a positive integer less than X.

According to the method, the network side equipment receives the reference signals in the alternative beam reference signal set reported according to the existing standard format, so that the network side equipment is convenient to detect and identify the reference signals, the working time is reduced, and the working efficiency is improved.

In a possible implementation manner, the received power value of at least one reference signal in the reference signals in the candidate beam reference signal set received by the network side device is a first special state value.

According to the method, the network side equipment can determine the beam corresponding to the reference signal reported by the terminal equipment as the alternative beam according to the first special state value, and continue to communicate on the alternative beam, so that the success rate of normal communication of the beam recovery is improved.

In a possible implementation manner, if the number of the reference signals in the reported candidate beam reference signal set is smaller than the number of the reported reference signals configured by the network side, and all the reference signals reported by the network side device through the PUCCH or PUSCH receive terminal device are reference signals in the candidate beam reference signal set, the remaining bit fields except the bit field of the reference signals in the reported candidate beam reference signal set are the second special state value.

According to the method, the network side equipment can normally receive the reference signal sent by the terminal equipment, the bit field occupied by the second special state value is meaningless according to the second special state value, the actual reference signals are all the reference signals in the alternative beam reference signal set, the corresponding alternative beams are found according to the actual reference signals, communication is continuously carried out on the remaining alternative beams, and the success rate of beam recovery is improved.

In a possible implementation manner, if the number of the reference signals in the reported candidate beam reference signal set is smaller than the number of the reported reference signals configured by the network side, and the network side device receives, through the PUCCH or the PUSCH, the reference signals reported by the terminal device as a combination of the reference signals in the candidate beam reference signal set and the L1-RSRP report, the L1-RSRP report uses an existing manner of mapping the reference signal reception power to the corresponding bit.

According to the method, the network side equipment can normally receive the reference signals reported by the terminal equipment and detect the received reference signals, when the reference signals in the alternative beam reference signal set and the reference signals corresponding to the L1-RSRP are determined to be reported, the corresponding beams are searched according to the two types of reference signals, and communication is continuously carried out on the beams corresponding to the reference signals in the received alternative beam reference signal set, and the success rate of the beam recovery normal communication is improved because a plurality of beams can carry out communication.

Detailed Description

The architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and it can be known by a person skilled in the art that with the occurrence of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

At present, the fifth generation mobile communication technology is gradually mature, in order to meet the requirements of the fifth generation mobile communication system, the high-frequency band spectrum resource with rich resources is used more, but the radio propagation anti-attenuation capability of the high-frequency band spectrum is weak, and continuous coverage is difficult to realize. When the terminal device determines that the quality of a beam for communicating with the network side device is poor, the terminal device needs to report a reference signal to the network side device, and when the network side device receives the reference signal, the corresponding beam is determined according to the quality of the reference signal and switched, so that the terminal device and the network side device can normally communicate with each other, and communication interruption is avoided.

In the prior art, a terminal device can only send a beam recovery request on one PRACH resource group at a time, only one reference signal can be reported at a time, a network side device communicates with the terminal device through a beam corresponding to the reference signal, and if the communication quality is poor, that is, the beam recovery is unsuccessful, the terminal device needs to send the beam recovery request to the network side device again. Because only one reference signal can be reported each time, the success rate of communication between the recovery network side device and the terminal device through the beam pair is low, and the communication needs to be sent for many times, so that the time delay is large, and the working efficiency is low.

Therefore, embodiments of the present invention provide a scheme for reporting a reference signal in an alternative beam reference signal set for beam recovery through a PUCCH or a PUSCH, and since a terminal device in an embodiment of the present invention may report a plurality of reference signals to a network side device through the PUCCH or the PUSCH at the same time, the network side device and the terminal device may communicate on beams corresponding to the plurality of reference signals, the number of beams used for communication is large, the success rate of normal communication is large, and a plurality of beams may be transmitted at one time, which reduces time delay and improves work efficiency.

The terminal equipment is equipment with a wireless communication function, can be deployed on land and comprises an indoor or outdoor, a handheld or a vehicle-mounted terminal; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, an industrial control (industrial control) wireless terminal device, a self driving (self driving) wireless terminal device, a remote medical (remote medical) wireless terminal device, a smart grid (smart grid) wireless terminal device, a transportation safety (transportation safety) wireless terminal device, a smart city (smart city) wireless terminal device, a smart home (smart home) wireless terminal device, etc.; but also UEs in various forms, Mobile Stations (MSs), the terminal equipment (terminal device).

The network side device is a device for providing a wireless communication function for the terminal device, and includes but is not limited to: a gbb in 5G, a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved node B or home node B, HNB), a BaseBand Unit (BBU), a transmission point (TRP), a Transmission Point (TP), a mobile switching center (msc), and the like. The base station in the present application may also be a device that provides the terminal device with a wireless communication function in other communication systems that may appear in the future.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a schematic structural diagram of a system for reporting and receiving a reference signal, where the system specifically includes:

the terminal device 10 is configured to receive the number of reported reference signals configured by the network side device; and reporting the reference signal in the at least one alternative beam reference signal set to network side equipment through a PUCCH or PUSCH.

The network side device 20 is configured to configure the number of the reported reference signals for the terminal device; and receiving the reference signal in the alternative beam reference signal set reported by the terminal equipment through a PUCCH or a PUSCH.

In the embodiment of the invention, the terminal equipment receives the number of the reported reference signals configured by the network side equipment, and reports the reference signals in at least one alternative beam reference signal set to the network side equipment through a PUCCH or PUSCH after determining the number of the reference signals needing to be reported; the terminal equipment can report the reference signals in the alternative beam reference signal set corresponding to the number of the configured reference signals to the network side equipment at one time through the PUCCH or PUSCH, and because the terminal equipment reports a plurality of reference signals, the beam recovery is carried out between the terminal equipment and the network side equipment on the beams corresponding to the plurality of reference signals, thereby improving the success rate of the beam recovery normal communication.

Specifically, when communication is interrupted between the network side device and the terminal device, the network side device may send a plurality of reference signals to the terminal device, and configure the number of reference signals to be reported for the terminal device according to the quality of the terminal device. Suppose that a network side device sends K reference signals to a terminal device, and reports N reference signals for the terminal device configuration.

After receiving the K reference signals sent by the network side device, the corresponding terminal device detects the reception power values of the K reference signals sent by the network side device, and reports the N reference signals to the network side device through the PUCCH or the PUSCH.

It should be noted that the K reference signals include reference signals in K1 candidate beam reference signal sets and reference signals in K2 previously used reference signal sets for L1-RSRP reporting.

The L1-RSRP reporting means that the content of CSI (Channel State Information) configured by the network side device for the terminal device includes: CSI-RSRP (CSI-RS Resource Indicator-Reference Signal Receiving Power), or None (null); the method is used for reporting the reference signal index and the corresponding receiving power to the network side equipment by the terminal equipment when communication interruption does not occur.

In the embodiment of the invention, when the terminal equipment reports the reference signal to the network side equipment, the priority of the reference signal in the candidate beam reference signal set is higher than the priority of the reference signal in the reference signal set for L1-RSRP reporting. When the number of the reference signals in the alternative beam reference signal set meets the reporting number configured by the network side equipment, the terminal equipment reports the reference signals in all the alternative beam reference signal sets; when the reference signals in the candidate beam reference signal set cannot satisfy the reporting number configured by the network side device, the reference signals reported by the terminal device to the network side device are a combination of the reference signals in the candidate beam reference signals and a special state bit field (referred to as a second special state value), or a combination of the reference signals in the candidate beam reference signal set and the reference signals in the reference signal set for L1-RSRP reporting.

Specifically, when the terminal device reports the reference signal to the network side device through the PUCCH or the PUSCH, a format of the reference signal in the reported candidate beam reference signal set is the same as a format of the report L1-RSRP in the existing standard.

When the terminal device reports the reference signal in the candidate beam reference signal set to the network side device, the terminal device mainly includes two parts, namely a reference signal index and a reference signal receiving power.

In the embodiment of the present invention, when a terminal device reports reference signals in an alternative beam reference signal set to a network side device, a format of the reported reference signals is related to a number of reports, which specifically includes the following steps:

the first method is as follows: if the number of the reported reference signals configured by the network side equipment received by the terminal equipment is equal to 1, when the terminal equipment reports the reference signals in the candidate beam reference signal set, reporting a received power value in the reference signals by adopting an X bit mode, wherein X is a positive integer.

For example, the number of the reported reference signals received by the terminal device and configured by the network side device is 1, and at this time, the received power value corresponding to the reference signal in the candidate beam reference signal set reported by the terminal device is converted into a format representation of X bit.

Correspondingly, the format of the reference signal in the candidate beam reference signal set reported by the terminal equipment, which is received by the network side equipment, is the reference signal index and the reference signal received power, and the reference signal received power is correspondingly in the form of X bit.

The second method comprises the following steps: if the number of the reported reference signals configured by the network side equipment received by the terminal equipment is greater than 1, reporting the reference signals by adopting a differential mode when the terminal equipment reports the reference signals in the candidate beam reference signal set, reporting the received power value of the reference signal with the maximum received power by adopting an X bit mode, and reporting the received power values of the rest of the reference signals by adopting Y bits, wherein Y is a positive integer smaller than X.

For example, the terminal device receives 2 reporting reference signals configured by the network side device, and if it is determined that the number of reporting is greater than 1, reports the reference signals in the candidate beam reference signal set in a differential manner, where a reception power value corresponding to the reference signal with the largest reception power is converted into a format of X bits for presentation, a reception power value of another reference signal is converted into a format of Y bits for presentation, and if X is a positive integer smaller than X, and Y is 7 and 4, the reception power value corresponding to the reference signal with the largest reception power is converted into a format of 7 bits for presentation, and the reception power value of another reference signal is converted into a format of 4 bits for presentation.

Correspondingly, the format of the reference signal in the candidate beam reference signal set reported by the terminal equipment received by the network side equipment is the reference signal index and the reference signal receiving power, and the receiving powers corresponding to the received reference signal are respectively in the forms of 7bit and 4 bit.

In implementation, the format in the existing standard is used for reporting the reference signal in the alternative beam reference signal set, so that the network side device can conveniently perform detection and identification, determine the beam corresponding to the received reference signal, and accelerate the working efficiency.

Based on the foregoing, the present invention will be briefly described by the following examples.

The first embodiment is as follows: the network side device configures and reports 1 reference signal (N is 1) for the terminal device.

In the embodiment of the present invention, a standard for identifying a reference signal in an alternative beam reference signal set is set between a terminal device and a network side device, that is, an RSRP value of a reference signal in the alternative beam reference signal set is set to be a first special state value, when the network side device detects that the RSRP value in the reference signal reported by the terminal device is the first special state value, it is determined that the received reference signal is the reference signal in the alternative beam reference signal set, and at this time, the network side device switches a beam to an alternative beam corresponding to the reference signal and communicates with the terminal device on the alternative beam.

The first special state value is set in advance by the terminal device and the network side device, and may be set to all "0" states or all "1" states, which is not limited herein and is only an example, and the first special state value is also applicable to the following embodiments.

Take the first special state value as all "0" states for example.

When the network side device configures and reports 1 reference signal for the terminal device, at this time, (T + X) bits can be adopted to report the reference signal, where T bit represents the reference signal index, and X bit represents the reference signal receiving power value. If the content reported by the terminal equipment is { X₁ X₂…X_T00 … 0}, after the network side device receives the content reported by the terminal device, the content reported by the terminal device is detected, the reference signal received power is determined to be all '0' state according to the detection result, at this time, the RSRP value of the reference signal is determined to be the first special state value, the reference signal reported by the terminal device is determined to be the reference signal in the alternative beam reference signal set, and thenThe network side equipment communicates with the terminal equipment on the alternative beam;

and if the reference signal received power received by the terminal equipment is not in a full '0' state, determining that the reference signal reported by the terminal equipment is a reference signal in a reference signal set for L1-RSRP reporting.

Example two: the network side equipment configures and reports N reference signals (N >1) for the terminal equipment, and the reference signals needing to be reported in K1 candidate beam reference signal sets sent by the network side equipment are greater than the number of the configured reported reference signals (K1> N), and at this time, all the N reference signals reported by the terminal equipment are the reference signals in the candidate beam reference signal sets.

In the embodiment of the present invention, a terminal device reports reference signals in multiple candidate beam reference signal sets to a network side device, and at this time, if the network device detects that an RSRP value of a reference signal in at least one candidate beam reference signal set is a first special state value, it is determined that all of the multiple reference signals reported by the terminal device are reference signals in the candidate beam reference signal set.

Take reporting two reference signals and the first special state value is all '0' state as an example.

At this time, when reporting the reference signal according to the format in the existing standard, reporting the reference signal in a differential mode, assuming that the reference signal is reported in the formats of (T + X) bit and (T + Y) bit, wherein T bit represents the reference signal index, X bit represents the reference signal receiving power value corresponding to the reference signal with the maximum receiving power when reporting, and Y bit represents the reference signal receiving power value corresponding to the other reported reference signals.

When the network side device determines that the reference signal receiving power value in at least one of the two reference signals reported by the terminal device is in a full '0' state, the reference signal reported by the terminal device is determined to be a reference signal in the alternative beam reference signal set, otherwise, the reference signal reported by the terminal device is a reference signal in the L1-RSRP reference signal set.

Specifically, the content reported by the terminal device may be in the following format:

the first format is as follows: x₁ X₂…X_T 0 0…0

X₁ X₂…X_T Y₁…Y_Y；

And a second format: x₁ X₂…X_T Y₁…Y_X

X₁ X₂…X_T 0 0…0；

And a third format: x₁ X₂…X_T 0 0…0

X₁ X₂…X_T 0 0…0；

When the network side device detects that the reference signal reported by the terminal device is any one of the three contents, the reference signal may be determined to be a reference signal in the candidate beam reference signal set reported by the terminal device, and at this time, the network side device and the terminal device continue to communicate in the candidate beam.

Wherein "Y" is₁…Y_X"and" Y₁…Y_Y"is any combination of" 0 "and" 1 "bits, and is not limited herein.

In implementation, a first special state value is set between the terminal device and the network side device, so that when the terminal device sends a reference signal to the network side device, the network side device can determine, according to the first special state value, that a beam corresponding to the reference signal reported by the terminal device is an alternative beam, and perform communication on the alternative beam, instead of performing communication using a beam with communication interruption before, thereby improving the success rate of beam recovery and performing normal communication.

Example three: the network side equipment configures and reports N reference signals (N >1) for the terminal equipment, but reference signals to be reported in K1 candidate beam reference signal sets sent by the network side equipment are smaller than the number of reported reference signals configured by the network side equipment (K1< N), at this time, the N reference signals reported by the terminal equipment contain the reference signals in the K1 candidate beam reference signal sets, and the rest bit fields are second special state values.

Optionally, if the number of the reference signals to be reported in the candidate beam reference signal set to be reported is smaller than the number of the reported reference signals configured by the network side, and all the reference signals reported by the terminal device to the network side device through the PUCCH or the PUSCH are the reference signals in the candidate beam reference signal set, the remaining bit fields except the bit field where the reference signals in the candidate beam reference signal set are reported are the second special state values.

In the embodiment of the present invention, a standard for confirming that there is no corresponding reference signal is set between the terminal device and the network side device, that is, when there is a bit field not filled with the reference signal in the reported reference signal, but the bit field not filled with the reference signal cannot be empty, at this time, a second special state value is set to fill the bit field not occupied by the reference signal, and there is no meaning, and there is no corresponding reference signal; it is only convenient for the network side device to normally receive the reference signal in the bit field occupied by the reference signal. When the network side device detects the second special state value, it can be determined that no reference signal exists at the position, but the reference signals at other positions are continuously detected.

The second special state value is set in advance by the terminal device and the network side device, and may be set to be a full "0" state or a full "1" state, which is not limited herein, but is merely an example.

And (3) reporting the reference signals by using the network side equipment as the terminal equipment configuration, but the terminal equipment can only report the reference signals in the reference signal set of 2 alternative beams, and the bit field of the remaining reference signal is occupied by the second special state value for example. Wherein, the first special state value is set as all '0' state, and the second special state value is set as all '1' state.

When the network side device determines that the reference signal receiving power value in at least one of the three reference signals reported by the terminal device is in a full '0' state and the received reference signal has a bit field occupied by a second special state value, it determines that all the reference signals reported by the terminal device are reference signals in the alternative beam reference signal set, and otherwise, the reference signals in the L1-RSRP reference signal set are reported.

The method comprises the steps that a network side device configures and reports three reference signals for a terminal device, the reported reference signals cannot be empty, the terminal device preferentially reports the reference signals in an alternative beam reference signal set when reporting the reference signals, a second special state value is used to occupy a bit field of the remaining reference signal because only the reference signals in two alternative beam reference signal sets exist in the terminal device, and the network side device determines that all the reference signals are the reference signals in the alternative beam reference signal set when detecting that a first special state value and a second special state value exist in the reported alternative reference signals because all the reported reference signals are the reference signals in the alternative beam reference signal set.

the first format is as follows: x₁ X₂…X_T 0 0…0

X₁ X₂…X_T Y₁…Y_Y

1 1……………1；

For format one, the three reference signals reported by the terminal equipment have a first special state value and a second special state value, and at this time, the network side equipment determines that the terminal equipment reports the reference signals in the two alternative beam reference signal sets.

And a second format: x₁ X₂…X_T Y₁…Y_X

X₁ X₂…X_T 0 0…0

1 1……………1；

For format two, the three reference signals reported by the terminal device have a first special state value and a second special state value, and at this time, the network side device determines that the terminal device reports the reference signals in the two candidate beam reference signal sets.

And a third format: x₁ X₂…X_T0 0…0

X₁ X₂…X_T 0 0…0

1 1……………1；

For format three, there are two first special state values and one second special state value in the three reference signals reported by the terminal device, and at this time, the network side device determines that the terminal device reports the reference signals in the two candidate beam reference signal sets.

For the above three formats, if the network side device detects that the bit field of one reference signal is occupied by the second special state value, it determines that there are two reference signals in the received three reference signals, and when the first special state value exists, the network side device determines that the two reference signals reported by the terminal device are both reference signals in the candidate beam reference signal set.

When the network side device detects that the terminal device reports any one of the three contents, it may determine that the terminal device reports a reference signal in the candidate beam reference signal set.

In implementation, the terminal device fills the bit fields except the reference signal bit field in the reported alternative beam reference signal set with the second special state value, so that the terminal device can normally report the reference signal to the network side device, and after the network side device receives the reference signal reported by the terminal device, the position filled with the second special state value can be determined to be meaningless, and then the reference signals in the remaining alternative beam reference signal set are detected and communicated on a plurality of alternative beams, communication is not performed on the beams with communication interruption before use, and the success rate of beam recovery for normal communication can be improved.

Example four: the network side equipment configures and reports N reference signals (N >1) for the terminal equipment, but reference signals to be reported in K1 candidate beam reference signal sets sent by the network side equipment are smaller than the number of the configured reported reference signals (K1< N), at this time, the N reference signals reported by the terminal equipment comprise reference signals in K1 candidate beam reference signal sets, and N-K1 reference signals in the reference signal sets for L1-RSRP reporting.

Optionally, if the number of the reference signals in the reported candidate beam reference signal set is smaller than the number of the reported reference signals configured by the network side, and the reference signal reported by the terminal device to the network side device through the PUCCH or the PUSCH is a combination of the reference signal in the candidate beam reference signal set and the L1-RSRP report, the L1-RSRP report uses an existing manner of mapping the reference signal reception power value to the corresponding bit.

When the number of reported reference signals configured by the network side device for the terminal device is greater than the number of reference signals in the candidate beam reference signal set sent by the network side device and the device to the terminal device, the terminal device may send a part of the reference signals in the candidate beam reference signal set and send a part of the reference signals in the reference signal set for L1-RSRP reporting when reporting the reference signals, and when sending the reference signals in the L1-RSRP reference signal set, the reception power values of the reference signals in the reference signal set for L1-RSRP reporting are mapped to a corresponding bit mode.

And (3) reporting reference signals by network side equipment configuration, wherein two reference signals are reference signals in the alternative beam reference signal set, and the first special state value is a full '0' state.

At this time, when reporting the reference signal according to the format in the existing standard, reporting the reference signal in a differential mode, assuming that the reference signal is reported in the formats of (T + X) bit and (T + Y) bit, wherein T bit represents a reference signal parameter index, X bit represents a reference signal receiving power value corresponding to the reference signal with the maximum receiving power when reporting, and Y bit represents a reference signal receiving power value corresponding to the other reported reference signals.

When determining the three reference signals reported by the terminal device, the received power of the reference signals in the two candidate beam reference signal sets reported at this time are both the first special state values, and the remaining received power values of the reference signals in the reference signal set for L1-RSRP reporting are mapped to the corresponding bit mode.

The network side equipment configures and reports three reference signals for the terminal equipment, the reported reference signals cannot be empty, when the terminal equipment reports the reference signals, the terminal equipment preferably reports the reference signals in the alternative beam reference signal set, because the terminal equipment only has the reference signals in two alternative beam reference signal sets, the terminal equipment reports the reference signals corresponding to the bit field of the rest reference signal by adopting an L1-RSRP reporting format, when the terminal equipment reports the reference signals by adopting the L1-RSRP reporting format, the bit field corresponding to the receiving power of the reference signals reported by L1-RSRP adopts a mode of ' 0 ' 1 ' bit converted according to the receiving power value of the reference signals, therefore, when the reference signals in the alternative beam reference signal set are reported, the RSRP values of the reference signals in all the alternative beam reference signal sets are expressed by a first special state value, and the method prevents the reference signal reporting in the alternative beam reference signal set from being mixed with the reference signal reporting in the reference signal set for L1-RSRP reporting.

Specifically, the content reported by the terminal device has the following format:

X₁ X₂…X_T 0 0…0

X₁ X₂…X_T R₁…R_X；

for the content format reported by the terminal equipment, the network side equipment preferentially reports the reference signals in the two candidate beam reference signal sets, the RSRP values of the reference signals in the candidate beam reference signal sets are mostly first special state values, and the RSRP values reported by L1-RSRP are ' 0 ' bit ' and ' 1 ' bit corresponding to the received power;

therefore, when the network side device receives the reference signals in the above format, the second special state value is not detected, but the RSRP values reported by L1-RSRP are detected, at this time, it is determined that the reference signals corresponding to the two first special state values are the reference signals in the candidate beam reference signal set, and the remaining one is reported by L1-RSRP.

The method comprises the steps that network side equipment receives three reference signals reported by terminal equipment, detects the receiving power of the reference signals in the three reference signals, determines two of the three reference signals as first special state values, indicates that the reference signals in an alternative wave beam reference signal set exist, and communicates with the terminal equipment after determining corresponding alternative wave beams according to the reference signals in the alternative wave beam reference signal set;

and the network side equipment determines that the bit of the reference signal received power of the other reference signal is a mode of mapping the reference signal received power into a corresponding bit, and then determines the bit as a reference signal in a reference signal set for L1-RSRP reporting, and determines the corresponding L1-RSRP according to the mapping relation between the reference signal received power and the bit.

In implementation, the terminal device fills the bit fields except the reference signal bit field in the reported alternative beam reference signal set with the second special state value, so that the terminal device can normally report the reference signal to the network side device, and after the network side device receives the reference signal reported by the terminal device, it can be determined that the position filled with the second special state value is meaningless, and then the reference signals in the remaining alternative beam reference signal set are detected, and communication is performed on a plurality of alternative beams, so that the success rate of beam recovery for normal communication can be improved.
