Description

Information processing and information indicating method and device

Technical field

This application relates to the field of communication technology, and in particular to methods and devices for information processing and information indication.

Background technique

In the unlicensed frequency band, all radio access technology (RAT) devices (such as network equipment, terminals, etc.) need to implement a listen before talk (LBT) mechanism before using the channel to send signals. In other words, the RAT device first determines whether the current channel is occupied before sending a signal, and only when the current channel is not occupied (that is, the LBT detection succeeds), the channel can be used to send a signal.

On unlicensed frequency bands, it can be based on synchronization signal broadcast channel block (synchronization signal physical broadcast channel block, SSB or SS/PBCH block) and/or non-zero-power CSI-RS (non-zero-power CSI-RS, NZP-CSI) -RS), to perform radio link monitoring (RLM) measurement or radio resource management (radio resource management, RRM) measurement. Among them, CSI-RS is the English abbreviation of channel state information reference signal (channel state information reference signal).

For communication systems working in unlicensed frequency bands, in RLM measurement/RRM measurement, it is possible that the network device has configured the terminal with the time-frequency resource occupied by the reference signal that needs to be measured, and the LBT detection performed by the network device fails. This will cause the network equipment to be unable to use the current channel, that is, the network equipment cannot send the reference signal. At this time, if the terminal performs RLM measurement/RRM measurement on the time-frequency resource configured by the network device, the measured received power is not the received power from the reference signal configured by the network device. Therefore, based on the measured received power It does not reflect the current link environment, that is, the RLM measurement/RRM measurement result is inaccurate, which leads to inaccurate RLM calculation/RRM calculation results performed subsequently using the measurement result.

It can be seen that the terminal determines whether the network device has sent the RLM reference signal or the RRM reference signal has become a technical problem to be solved urgently.

Summary of the invention

The embodiments of the present application provide methods and devices for information processing and information indication, which can enable a terminal to determine whether a network device has sent an RLM reference signal or an RRM reference signal.

In a first aspect, an information processing method is provided, which is applied to a receiving end device (such as a terminal or a network device). The method includes: acquiring the received power of a first reference signal mapped on a first time-frequency resource; The frequency resource is the time-frequency resource occupied by the RLM reference signal/RRM reference signal (ie, RLM-RS/RRM-RS) of the receiving end device. Acquire the received power of the second reference signal mapped on the second time-frequency resource; wherein the second time-frequency resource does not overlap with the first time-frequency resource. According to the received power of the first reference signal and the received power of the second reference signal, it is determined whether the transmitting end device has transmitted the RLM reference signal/RRM reference signal on the first time-frequency resource.

Since the sender device sends RLM-RS/RRM-RS and does not send RLM-RS/RRM-RS on the same time-frequency resource, the reference signal received by the receiver device on the time-frequency resource ( That is, the received power of the first reference signal) is different. Therefore, by introducing the second reference signal and using the received power of the second reference signal as a reference, it helps to determine whether the transmitting end device sends the RLM on the first time-frequency resource. -RS/RRM-RS. For example, performing the same operation on the received power of the second reference signal and the different received power will result in different results. Based on this, by pre-defining one or more operating rules between the received power of the second reference signal and the received power of the first reference signal, it can be determined whether the transmitting end device has sent RLM- on the first time-frequency resource. RS/RRM-RS.

In addition, in this technical solution, when performing RLM measurement/RRM measurement, the receiving end device can autonomously determine whether the transmitting end device has sent RLM-RS/RRM-RS on the configured corresponding time-frequency resources, without the need to configure RLM -The participation of RS/RRM-RS equipment (which can be a sender device or a network device). Therefore, it helps to improve the flexibility of the communication system. In addition, after the receiving end device determines whether RLM-RS/RRM-RS is transmitted on the corresponding configured time-frequency resource, it can further determine whether to use the received power of the first reference signal for RLM calculation/RRM calculation. Therefore, there is Helps improve the accuracy of RLM calculation/RRM calculation results.

In an example, the sending end device and the receiving end device are a network device and a terminal, respectively.

In another example, both the sending end device and the receiving end device are network devices.

In yet another example, both the sending end device and the receiving end device are terminals.

Optionally, based on any of these examples, the time-frequency resources occupied by the RLM reference signal/RRM reference signal of the receiving end device refer to the RLM reference signal/RRM reference signal configured by the transmitting end device to the receiving end device. The time-frequency resources occupied by the signal.

Optionally, when the receiving end device is a terminal (where the sending end device can be a network device or a terminal), the time-frequency resources occupied by the RLM reference signal/RRM reference signal of the receiving end device all refer to the configuration of the network device The time-frequency resource occupied by the RLM reference signal/RRM reference signal of the receiving end device.

In a possible design, the time interval between the first time-frequency resource and the second time-frequency resource is smaller than the first threshold. In this way, it is helpful to improve the accuracy of the receiving end device in determining whether the transmitting end device has sent the RLM reference signal/RRM reference signal on the first time-frequency resource.

For example, the first time-frequency resource and the second time-frequency resource occupy the same subframe, the same time slot, or the same symbol.

In a possible design, the frequency domain interval between the first time-frequency resource and the second time-frequency resource is smaller than the second threshold. In this way, it is helpful to improve the accuracy of the receiving end device in determining whether the transmitting end device has sent the RLM reference signal/RRM reference signal on the first time-frequency resource.

For example, the first time-frequency resource and the second time-frequency resource occupy the same PRB, the same BWP, or the same subcarrier.

In a possible design, there is a QCL relationship between the RLM-RS/RRM-RS and the second reference signal, or the transmission beam used for transmitting the RLM-RS/RRM-RS and when the second reference signal is transmitted The transmission beams used are the same (or similar). In this way, it is helpful to improve the accuracy of the receiving end device in determining whether the transmitting end device has sent the RLM reference signal/RRM reference signal on the first time-frequency resource.

In a possible design, the method further includes: receiving first indication information, where the first indication information is used to indicate an association relationship between the RLM reference signal resource/RRM reference signal resource and the second reference signal resource. In this case, determining whether the transmitting end device has transmitted the RLM reference signal/RRM reference signal on the first time-frequency resource according to the received power of the first reference signal and the received power of the second reference signal includes: according to the first indication information , The received power of the first reference signal and the received power of the second reference signal, and determine whether the transmitting end device has transmitted the RLM reference signal/RRM reference signal on the first time-frequency resource.

This possible design provides a technical solution for enabling the receiving end device to learn the "association relationship between the RLM reference signal resource/RRM reference signal resource and the second reference signal resource" through signaling interaction. In actual implementation, the association relationship may be predefined, such as predefined through an agreement.

In a possible design, the method further includes: receiving second indication information, where the second indication information is used to indicate the position of the time-frequency resource occupied by the second reference signal, for example, by indicating the port number corresponding to the second reference signal , The sequence number of the second reference signal, etc. indirectly indicate the position of the time-frequency resource occupied by the second reference signal, or the position of the time-frequency resource is indicated by the index of the time-frequency resource occupied by the second reference signal.

In a possible design, the method further includes: receiving third indication information, where the third indication information is used to indicate the position of the time-frequency resource occupied by the RLM reference signal/RRM reference signal.

For any of the foregoing indication information (including any one of the first indication information to the third indication information), it may be sent by the sending end device. Or, when the receiving end device is a terminal (the sending end device may be a network device or a terminal), the indication information may be sent by the network device.

For any of the foregoing indication information (including any one of the first indication information to the third indication information), it can be carried in one or a combination of RRC signaling, MAC signaling, and DCI. Configured.

In a possible design, the RLM reference signal resource/RRM reference signal resource may only have an association relationship with the second reference signal resource, or the RLM reference signal resource/RRM reference signal resource may also be associated with other second reference signal resources. The signal resources have an association relationship, or other RLM reference signal resources/RRM reference signal resources may also have an association relationship with the second reference signal resource.

That is to say, the RLM reference signal resource/RRM reference signal resource with an association relationship and the second reference signal resource (also can be referred to as an RLM reference signal/RRM reference signal with an association relationship and the second reference signal) may be one. One-to-one, one-to-many, or many-to-one relationships, of course, can also be many-to-many relationships.

In a possible design, the RLM reference signal/RRM reference signal includes: SSB or NZP-CSI-RS.

In a possible design, the transmit power of the second reference signal is less than the threshold, for example, the transmit power of the second reference signal is equal to zero.

In a possible design, the second reference signal includes: ZP-CSI-RS.

In a possible design, according to the received power of the first reference signal and the received power of the second reference signal, it is determined whether the transmitting end device has transmitted the RLM reference signal/RRM reference signal on the first time-frequency resource, including: When the difference between the received power of the second reference signal and the received power of the first reference signal is greater than or equal to the third threshold, it is determined that the transmitting end device has transmitted the RLM reference signal/RRM reference signal on the first time-frequency resource; When the difference between the received power of the second reference signal and the received power of the first reference signal is less than the third threshold, it is determined that the transmitting end device does not send the RLM reference signal/RRM reference signal on the first time-frequency resource.

This is in consideration of "if the sending end device sends RLM-RS/RRM-RS on the first time-frequency resource, the first reference signal (that is, the RLM-RS/RRM-RS) obtained by the receiving end device The received power is usually large, which will cause the received power of the first reference signal to differ greatly from the received power of the second reference signal; if the transmitting end device does not send RLM-RS/RRM-RS on the first time-frequency resource, then The received power of the first reference signal (such as noise, etc.) obtained by the receiving end device is usually small, which will make the received power of the first reference signal and the received power of the second reference signal not much different from the technical solution proposed. This calculation is simple, convenient and easy to implement.

It should be noted that the RLM-RS/RRM-RS is specifically RLM-RS, the second reference signal is specifically ZP-CSI-RS, and the receiving end device is a terminal as an example: because the NR system supports the configuration of ZP-CSI- Interference measurement is performed in the CSI interference measurement (CSI-IM) of the RS. REs configured with CSI-IM only have signal power from other access devices (including internal operating units). For RLM-RS, in REs configured with RLM-RS, there is also useful signal power from the serving unit. After quantization, the signal power in the REs occupied by RLM-RS can be regarded as the sum of the power of other interference signals and the useful signal power of the service unit. Therefore, the terminal can compare the energy detection of the target frequency resources (REs) configured with ZP-CSI-RS and RLM-RS, and then determine whether the RLM-RS is successfully transmitted. If the measurement results of ZP-CSI-RS and RLM-RS are almost the same, or less than the preset threshold, the terminal can assume that the configured RLM-RS is not successfully transmitted.

In a possible design, the above-mentioned threshold (such as the first threshold, the second threshold, or the third threshold) can be configured by the transmitting device through signaling (such as RRC signaling, MAC signaling, or DCI). , Or can be pre-defined (for example, pre-defined by agreement).

In a possible design, the foregoing steps of obtaining the received power of the first reference signal and the received power of the second reference signal are performed by the L1 layer of the receiving end device.

In a possible design, the method may further include: when it is determined that the transmitting end device has transmitted the RRM reference signal on the first time-frequency resource, performing RLM calculation/RRM calculation using the received power of the first reference signal. When it is determined that the transmitting end device does not transmit the RRM reference signal on the first time-frequency resource, the received power of the first reference signal is not used for RLM calculation/RRM calculation. In this way, it is helpful to provide the accuracy of the RRM calculation result when the RRM calculation is performed on the L3 layer.

In a possible design, according to the received power of the first reference signal and the received power of the second reference signal, it is determined whether the transmitting end device has transmitted the RLM reference signal/RRM reference signal on the first time-frequency resource, including: When the RLM reference signal/RRM reference signal is an RRM reference signal, the L1 layer of the receiving end device determines whether the transmitting end device transmits on the first time-frequency resource according to the received power of the first reference signal and the received power of the second reference signal RRM reference signal. The method may further include: when it is determined that the transmitting end device has transmitted the RRM reference signal on the first time-frequency resource, the L1 layer of the receiving end device sends the received power of the first reference signal to the L3 layer of the receiving end device. This possible design provides a mechanism for "during RRM measurement, the L1 layer reports the measured received power of the reference signal (ie the first reference signal) to the L3 layer", which helps to perform RRM at the L3 layer When calculating, provide the accuracy of the RRM calculation result.

In a possible design, according to the received power of the first reference signal and the received power of the second reference signal, it is determined whether the transmitting end device has transmitted the RLM reference signal/RRM reference signal on the first time-frequency resource, including: When the RLM reference signal/RRM reference signal is an RRM reference signal, the L3 layer of the receiving end device determines whether the transmitting end device transmits on the first time-frequency resource according to the received power of the first reference signal and the received power of the second reference signal RLM reference signal/RRM reference signal.

This possible design provides a mechanism for "During RRM calculation, the L3 layer of the receiving end device determines the effective RRM measurement", which helps to provide the accuracy of the RRM calculation result when the RRM calculation is performed at the L3 layer.

In a possible design, it is determined whether the transmitting end device has transmitted the RLM reference signal/RRM reference signal on the first time-frequency resource, which is equivalent to whether the RRM measurement of the receiving end device based on the first reference signal is a valid RLM Reference signal/RRM reference signal.

Specifically, the sending end device sends the RLM reference signal/RRM reference signal on the first time-frequency resource, which is equivalent to that the RRM measurement of the receiving end device based on the first reference signal is a valid RRM measurement; the sending end device is not in the first time-frequency resource. Sending an RLM reference signal/RRM reference signal on a time-frequency resource is equivalent to that the RRM measurement of the receiving end device based on the first reference signal is not a valid RRM measurement.

In a second aspect, an information indication method is provided, the method comprising: generating indication information, the indication information being used to indicate an association relationship between an RLM reference signal resource/RRM reference signal resource and a second reference signal resource. Wherein, the time-frequency resource occupied by the RLM reference signal/RRM reference signal is the first time-frequency resource, the time-frequency resource occupied by the second reference signal is the second time-frequency resource, and the first time-frequency resource and the second time-frequency resource are Resources do not overlap. The association relationship is used by the receiving end device to determine whether the transmitting end device has sent the RLM reference signal/RRM reference signal on the first time-frequency resource; and sending the indication information to the receiving end device.

This method can be applied to the sending end device. Or, when the receiving end device is a terminal (wherein, the sending end device may be a terminal or a network device), the method can be applied to a network device.

In a possible design, the time interval between the first time-frequency resource and the second time-frequency resource is smaller than the first threshold. For example, the first time-frequency resource and the second time-frequency resource occupy the same subframe, the same time slot or the same symbol.

In a possible design, the frequency domain interval between the first time-frequency resource and the second time-frequency resource is smaller than the second threshold. For example, the first time-frequency resource and the second time-frequency resource occupy the same PRB, bandwidth BWP, or the same subcarrier.

In a possible design, there is a QCL relationship between the RLM-RS/RRM-RS and the second reference signal.

Hereinafter, in conjunction with the drawings, the technical solutions provided by the embodiments of the present application will be described through the configuration phase and the information processing phase. As an example, the configuration phase can be considered as the basis of the information processing phase.

Configuration phase

As shown in FIG. 5, it is a schematic diagram of interaction of a configuration method provided by an embodiment of this application. The method may include the following steps:

S101: The network device generates indication information, which is used to indicate the time-frequency resources occupied by the RLM-RS/RRM-RS, the time-frequency resources occupied by the second reference signal, and the RLM-RS/RRM-RS resources and the second reference signal. 2. The association relationship between the reference signal resources (equivalent to the association relationship between the RLM-RS/RRM-RS and the second reference signal). The time-frequency resources occupied by the reference signals with the association relationship do not overlap.

RLM-RS/RRM-RS may be SSB and/or NZP-CSI-RS. The second reference signal may be ZP-CSI-RS.

If an RLM-RS resource/RRM-RS resource has an association relationship with a second reference signal resource, in the information processing stage, the terminal can determine whether the network device uses the RLM-RS resource/RRM based on the second reference signal -RS resource sent RLM-RS/RRM-RS.

If one RLM-RS resource/RRM-RS resource has an association relationship with a second reference signal resource, it can be considered that there is an association relationship between the RLM-RS/RRM-RS and the second reference signal.

In actual implementation, the number of RLM-RS/RRM-RS configured by the network device to the terminal is more than one. Accordingly, the network device may configure one or more second reference signals to the terminal. In addition, the correspondence between RLM-RS/RRM-RS and the second reference signal (or RLM-RS resource/RRM-RS resource and the second reference signal resource) may be one-to-one, one-to-many, and many-to-one. Or a many-to-many relationship. The corresponding relationship is used to characterize that the terminal can use several second reference signals to determine whether the network device has sent several RLM-RS/RRM-RS. That is, the network device can configure one or more second reference signals to the terminal to assist the terminal in determining whether the network device sends an RLM-RS/RRM-RS, or; configure a second reference signal to the terminal to assist The terminal determines whether the network device has sent multiple RLM-RS/RRM-RS.

The time-frequency resources occupied by the reference signals with the association relationship do not overlap, which means that the reference signals with the association relationship do not occupy the same time-frequency resource. However, time-frequency resources can be frequency-division multiplexed or time-frequency resources can be time-division multiplexed between reference signals with an association relationship. Of course, it is also possible to neither frequency division multiplex nor time division multiplex time-frequency resources.

S102: The network device sends the instruction information to the terminal.

The information indicated by the instruction information is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed. For example, the information to be instructed can be directly indicated, such as through the information to be instructed itself or the information to be instructed. The index directly indicates the information to be indicated. For example, the information to be indicated can be indicated indirectly by indicating other information, where there is an association relationship between the other information and the information to be indicated. For example, only part of the information to be indicated may be indicated, while other parts of the information to be indicated are known or agreed in advance. For example, it is possible to realize the indication of specific information by means of the pre-arranged order (such as stipulated in the agreement) of the various information, so as to reduce the indication overhead to a certain extent. For example, the common parts of each information can be identified and unified instructions, so as to reduce the instruction overhead caused by separately indicating the same information.

In addition, the specific instruction method may be various existing instruction methods, for example, the foregoing instruction methods and various combinations thereof. In the specific implementation process, the required instruction method can be selected according to specific needs. The embodiment of the application does not limit the selected instruction method. As a result, the instruction method involved in the embodiment of the application should be understood as covering that can make the instruction to be instructed Various methods for obtaining information to be indicated.

The technical solutions provided in the embodiments of the present application should be understood to cover various forms. For example, some or all of the characteristics involved in the embodiments of the present application should be understood to cover various manifestations of the characteristics.

The indication information can be sent together as a whole, or can be divided into multiple sub-information and sent separately, and the sending period and/or sending timing of these sub-information can be the same or different. The specific sending method is not limited in this application. The sending period and/or sending timing of these sub-information may be pre-defined, for example, pre-defined according to a protocol, or configured by the network device by sending configuration information to the terminal.

In an example, the indication information may include: location information of time-frequency resources occupied by one or more RLM-RS/RRM-RS, location information of time-frequency resources occupied by one or more second reference signals, And which RLM-RS/RRM-RS has an association relationship with which or which second reference signal. In this example, the association relationship is explicitly indicated. Based on this example, any one or more pieces of information included in the instruction information can be sent together as a whole, or divided into multiple sub-information to be sent separately.

In another example, the indication information may include: location information of time-frequency resources occupied by one or more RLM-RS/RRM-RS, and locations of time-frequency resources occupied by one or more second reference signals information. In this example, the information included in the indication information may be sent together as a whole to implicitly indicate that there is an association relationship between the one or more RLM-RS/RRM-RS and the one or more second reference signals. In this way, signaling transmission overhead can be saved. For example, assuming that a piece of signaling carries the location information of the time-frequency resources occupied by RLM-RS/RRM-RS1~2 and the location information of the time-frequency resources occupied by the second reference signal 1, then the RLM-RS/RRM -RS1 and RLM-RS/RRM-RS2 both have an association relationship with the second reference signal 1.

Taking the second reference signal as ZP-CSI-RS as an example, the position of the time-frequency resource occupied by the ZP-CSI-RS can be configured by configuring the ZP-CSI-RS sequence number, where the ZP-CSI-RS sequence number and ZP -The positions of the time-frequency resources occupied by the CSI-RS correspond one-to-one. The ZP-CSI-RS sequence number configuration method may include one of the following implementation methods:

Manner 1: The number of ZP-CSI-RS in this manner may correspond to the "zp-CSI-RS-ResourceId" in the TS38.331 parameter "ZP-CSI-RS-Resource". For example, assuming that the location of the time-frequency resources occupied by ZP-CSI-RS is shown in figure b in Figure 4, and the ZP-CSI sequence numbers are {2, 4, 5, 8} respectively, then in this embodiment of the application, The configured ZP-CSI-RS sequence numbers may be {2, 4, 5, 8} respectively.

Method 2: The number of ZP-CSI-RS in this method can be independent of the "zp-CSI-RS-ResourceId" in the TS38.331 parameter "ZP-CSI-RS-Resource". The number of "zp-CSI-RS-ResourceId" is renumbered. For example, assuming that the location of the time-frequency resources occupied by ZP-CSI-RS is shown in figure b in Figure 4, and the ZP-CSI sequence numbers are {2, 4, 5, 8} respectively, then in this embodiment of the application, The configured ZP-CSI-RS sequence number can be renumbered as {1,2,3,4}.

The indication information may be realized by, for example, but not limited to, one or a combination of at least two of RRC signaling, MAC signaling, and DCI. For example, one or a combination of at least two of RRC signaling, MAC signaling and DCI is used to indicate the location of the time-frequency resources occupied by RLM-RS/RRM-RS, that is, the network equipment can be configured with periodicity/aperiodicity (Ie semi-statically or dynamically) RLM-RS/RRM-RS. For another example, one or a combination of at least two of RRC signaling, MAC signaling, and DCI is used to indicate the position of the time-frequency resource occupied by the second reference signal, that is, the network device can configure the periodic/aperiodic first 2. Reference signal.

S103: The terminal receives the instruction information.

In specific implementation, the configuration phase is optional, or part of the information configured in the configuration phase (that is, part of the information indicated by the indication information) is optional. For example, if part of the information indicated by the above-mentioned indication information has been predefined (such as stipulated by a protocol), this part of information may not be configured in the configuration phase. For another example, if all the information indicated by the above-mentioned instruction information has been predefined (such as stipulated by a protocol), the network device and the terminal may not execute each step in the above-mentioned configuration phase. In order to clearly describe the technical solutions provided by the embodiments of the present application, in some descriptions (or examples) of the present application, the network device configures the terminal with the information indicated by the above-mentioned instruction information as an example for description. , I won’t repeat it below.

In an embodiment, the time interval between the time-frequency resources occupied by the reference signals with the association relationship is less than the first threshold. That is to say, in the time domain, the time-frequency resources occupied by the reference signals with the association relationship are within the coherent time. Among them, the coherence time can be understood as being within a certain time interval.

For example, the first threshold may be pre-defined as stipulated by the protocol, or may be configured through RRC signaling, MAC signaling, or DCI. For example, the first threshold may be one or more subframes, or one or more time slots, or one or more symbols.

Optionally, the time-frequency resources occupied by the reference signals with the association relationship occupy the same subframe or the same time slot or the same symbol. In this case, it can be considered that the time interval between the time-frequency resources occupied by the reference signals with the association relationship is less than the first threshold.

In another embodiment, the frequency domain interval between the time-frequency resources occupied by the reference signals with the associated time-frequency resources and the associated time-frequency resources is smaller than the second threshold. That is to say, in the frequency domain, the time-frequency resource occupied by the reference signal with the associated time-frequency resource is within the coherent bandwidth. Among them, the coherent bandwidth is an important parameter of the multipath channel characteristics. It refers to a specific frequency range in which any two frequency components have a strong amplitude correlation. The multipath channel has constant gain and linear phase. In a wireless communication system, if the bandwidth of the signal is smaller than the coherent bandwidth of the channel, the received signal will experience a flat fading process. At this time, the spectral characteristics of the transmitted signal can still remain unchanged in the receiver. If the bandwidth of the signal is greater than the coherent bandwidth of the channel, the received signal will experience frequency selective fading. At this time, some frequencies of the received signal gain greater gain than other components, which causes distortion of the received signal and causes inter-symbol interference. .

For example, the second threshold may be predefined as specified by the protocol, or may be configured through RRC signaling, MAC signaling, or DCI. For example, the second threshold may be one or more same physical resource blocks (PRB), or one or more subcarriers, etc.

Optionally, the time-frequency resources occupied by the reference signals with the association relationship occupy the same PRB, bandwidth part (BWP), or the same subcarrier. In this case, it can be considered that the frequency domain interval between the time-frequency resources occupied by the reference signals with the association relationship is smaller than the second threshold.

In another embodiment, the RLM-RS/RRM-RS having an association relationship and the second reference signal have a quasi co-located (QCL) relationship, or the RLM-RS/RRM-RS is sent and the second reference signal is sent. The transmission beams used for the second reference signal are the same (or similar).

Wherein, quasi co-location is used to indicate that multiple resources have one or more identical or similar communication features. For multiple resources with quasi co-location, the same or similar communication configuration can be adopted. For example, if two antenna ports have a co-location relationship, then the large-scale characteristics of the channel transmitting one symbol on one port can be inferred from the large-scale characteristics of the channel transmitting one symbol on the other port. Among them, the large-scale characteristics can include: delay spread, average delay, Doppler spread, Doppler shift, average gain, terminal device receiving beam number, transmit/receive channel correlation, receive arrival angle, receiver antenna space Relevance, etc.

In yet another implementation manner, the time-frequency resource can be frequency-division multiplexed, or the time-frequency resource can be time-division multiplexed, or neither can be frequency-division multiplexed between the associated RLM-RS/RRM-RS and the second reference signal Time-frequency resources are multiplexed time-frequency resources from time to time.

It should be noted that, if there is no conflict, some or all of the technical features in any of the above embodiments can be combined to obtain a new embodiment. For example, the correspondence between the periodic RLM-RS/RRM-RS and the periodic/aperiodic second reference signal is one-to-one, one-to-many, many-to-one, or many-to-many. For another example, the time-frequency resources occupied by the reference signals with the association relationship are within the coherence time and within the coherence bandwidth.

The following describes the relationship between the RLM-RS/RRM-RS with a mapping relationship and the time-frequency resources occupied by the second reference signal provided by the embodiment of the present application. In the following description, the second reference signal is ZP-CSI-RS as an example.

Optionally, when configuring aperiodic ZP-CSI-RS, it can be specifically configured in one of the following ways:

Method 1: Continue to use the field DCI 1_1 in the current R15NR system to configure ZP-CSI-RS, that is, trigger the configuration of ZP-CSI-RS through the "ZP CSI-RS trigger" field in the DCI. When the physical downlink shared channel (PDSCH) is configured for multi-slot transmission, one trigger is valid for all time slots scheduled by the DCI. The length of the "ZP CSI-RS trigger" field can be expressed as

Among them, n _ZP is the number of parameters "ZP-CSI-RS-ResourceSet" allowed to be configured by the upper layer. For example, when n _ZP is 2 bits, you can use bits 01/10/11 to represent ResourceSet ID 1/2/3, 00 reserved.

Method 2: In the unlicensed frequency band, define group common PDCCH (group common PDCCH, GC PDCCH), PDCCH is the English abbreviation of physical download control channel (physical download control channel), GC-PDCCH channel means that the network equipment successfully occupies the channel A cell-level control signaling sent afterwards mainly contains fields such as time slot indication and channel occupancy time (COT) information. Considering that the ZP-CSI-RS configuration method is also at the cell level, the information used to configure the ZP-CSI-RS can be added to the GC-PDCCH. Its resource mapping method (for example, "CSI-RS-ResourceMapping" in "ResourceMapping" in RRC signaling) can still use the resource mapping method of NZP-CSI-RS. Through this configuration method, SSB and ZP-CSI-RS can be better combined.

Example 1

In this embodiment, the RLM-RS/RRM-RS is SSB and the second reference signal is ZP-CSI-RS as an example for description.

In the following, taking the one-to-many relationship between an SSB and its associated ZP-CSI-RS as an example, the positions of time-frequency resources occupied by one SSB and its associated ZP-CSI-RS are exemplified. Description:

1) One SSB and its associated multiple ZP-CSI-RS occupy the same time slot.

Based on this, a SSB and any ZP-CSI-RS associated with it can frequency division multiplex time-frequency resources, or time-division multiplex time-frequency resources, or neither frequency-division multiplex nor time-division multiplex time-frequency resources .

6A to 6C and 7A to 7B are schematic diagrams of the time-frequency resource positions of each reference signal when one SSB and its associated multiple ZP-CSI-RS occupy the same time slot. Among them, the figures in these figures all take the association between one SSB and four ZP-CSI-RSs as examples, and in these figures, the SSB and ZP pointed to by the thick double-headed arrows -There is an association relationship between CSI-RS.

The time-frequency resource positions of the four ZP-CSI-RSs shown in FIG. 6A to FIG. 6C may be as shown in diagram a or diagram c in FIG. 4. Among them, in FIG. 6A, the SSB and its associated 4 ZP-CSI-RS frequency division multiplexing time-frequency resources. In FIG. 6B, the time-frequency resources are time-division multiplexed between the SSB and its associated 4 ZP-CSI-RS. In FIG. 6C, the SSB and its associated 4 ZP-CSI-RS neither frequency division multiplex time-frequency resources nor time-frequency resources.

The time-frequency resource positions of the four ZP-CSI-RSs shown in FIG. 7A to FIG. 7B may be as shown in diagram b in FIG. 4. Among them, in FIG. 7A, the SSB and its associated 4 ZP-CSI-RS frequency division multiplex time-frequency resources. In Figure 7B, the SSB and some of the four ZP-CSI-RSs associated with ZP-CSI-RS (such as ZP-CSI-RS on symbol 5 and symbol 12) frequency division multiplex time-frequency resources, part ZP-CSI-RS (such as ZP-CSI-RS on symbol 6 and symbol 13) neither frequency division multiplexes time-frequency resources nor time-frequency resources.

It should be noted that the foregoing is only an example, and it does not limit the location of the time-frequency resources occupied by the provided SSB and its associated multiple ZP-CSI-RS in the application embodiment. For example, when the SSB and its associated 4 ZP-CSI-RS frequency division multiplexing time-frequency resources, these 4 ZP-CSI-RS may not be located on the symbol 4 shown in FIG. 6A, but It is located on symbol 2 or symbol 3 or symbol 5 in FIG. 6A.

It should be noted that the above are all described by taking the positions of the time-frequency resources occupied by the SSB configured in slot 0 and its associated multiple ZP-CSI-RSs as examples. In one example, the configuration window The time-frequency resources occupied by the configured SSB and its associated multiple ZP-CSI-RS in each time slot are the same as the configured SSB and its associated multiple ZP-CSI-RS in time slot 0 The time-frequency resources occupied by the RS are shown.

2) One SSB and its associated multiple ZP-CSI-RS do not occupy the same time slot.

Based on this, one SSB and any ZP-CSI-RS associated with it can neither frequency division multiplex nor time division multiplex time-frequency resources.

As shown in FIG. 8A to FIG. 8B, it is a schematic diagram of the time-frequency resource position of each reference signal when one SSB and its associated multiple ZP-CSI-RSs do not occupy the same time slot. Among them, Figure 8A ~ Figure 8B take the association relationship between one SSB and 4 ZP-CSI-RS as an example for description, and the SSB and ZP-CSI-RS pointed to by the thick double-headed arrow are associated with each other. relationship. The time-frequency resource positions of the four ZP-CSI-RSs in FIG. 8A to FIG. 8B may be as shown in the diagram a or the diagram c in FIG. 4.

It is understandable that in Figures 8A and 6A, the time-frequency resource position occupied by SSB and the time-frequency resource position occupied by ZP-CSI-RS are the same. The difference between the two is that SSB and ZP-CSI-RS The association relationship between RSs is different. Similarly, FIG. 8B can be obtained based on FIG. 6B. It can be seen that, based on Figure 6C, Figure 7A and Figure 7B, those skilled in the art can obtain the time-frequency resources of each reference signal when one SSB and its associated multiple ZP-CSI-RSs do not occupy the same time slot. Schematic diagram of the location.

Example 2

In this embodiment, the RLM-RS/RRM-RS is NZP-CSI-RS, and the second reference signal is ZP-CSI-RS as an example for description. As an example, the time-frequency resource occupied by one NZP-CSI-RS is one RE.

9A to 9C, FIG. 10, and FIG. 11 are schematic diagrams of the time-frequency resource positions occupied by NZP-CSI-RS and ZP-CSI-RS that have an association relationship. In these figures, the NZP-CSI-RS and the ZP-CSI-RS pointed to by the thick double-headed arrows have an association relationship. specific:

In FIGS. 9A to 9C, NZP-CSI-RS and ZP-CSI-RS with an association relationship are time-division multiplexed with time-frequency resources. FIGS. 9A to 9C respectively illustrate examples of the correspondence between NZP-CSI-RS and ZP-CSI-RS, which is one-to-one, one-to-many, and many-to-one.

In FIG. 10, NZP-CSI-RS and ZP-CSI-RS with an association relationship are frequency division multiplexed time-frequency resources. Figures a, b, and c of FIG. 10 respectively illustrate examples of the one-to-one, one-to-many, and many-to-one correspondences between NZP-CSI-RS and ZP-CSI-RS.

In FIG. 11, the NZP-CSI-RS and the ZP-CSI-RS having an association relationship neither frequency-division time-domain resources nor frequency-division-frequency domain resources are taken as an example for description. Figures a, b, and c in FIG. 11 respectively take the corresponding relationship between NZP-CSI-RS and ZP-CSI-RS as one-to-one, one-to-many, and many-to-one as examples.

It is understandable that the above is only an example, and it does not limit the time-frequency resource positions occupied by the associated NZP-CSI-RS and ZP-CSI-RS that are applicable to the embodiments of the present application. For example, the REs occupied by the NZP-CSI-RS and the ZP-CSI-RS that have an association relationship may be adjacent or separated by a certain distance. For another example, when the correspondence between NZP-CSI-RS and ZP-CSI-RS is one-to-many, NZP-CSI-RS can time/frequency multiplex time-frequency resources with part of ZP-CSI-RS, Or neither time-division nor frequency-division time-frequency resources; time-division/frequency-division multiplexing time-frequency resources with another part of ZP-CSI-RS, or neither time-division nor frequency-division time-frequency resources.

Information processing stage

As shown in FIG. 12, it is a schematic diagram of interaction of an information processing method provided by an embodiment of this application. The method may include the following steps:

S201: The network device performs LBT detection after sending the foregoing instruction information to the terminal (for example, performing the foregoing S102). If the LBT detection is successful, the RLM-RS/RRM-RS is sent to the terminal on the first time-frequency resource. If the LBT detection fails, the RLM-RS/RRM-RS is not sent on the first time-frequency resource. Among them, the first time-frequency resource is the time-frequency resource occupied by one RLM-RS/RRM-RS configured to the terminal by the network device.

For the specific implementation of step S201, reference may be made to the prior art.

If in the configuration phase, the network device configures the terminal with multiple RLM-RS/RRM-RS positions, as an example, the network device can perform one time before sending each RLM-RS/RRM-RS LBT testing.

For the terminal, the time-frequency resource occupied by each RLM-RS/RRM-RS configured by the network device can be used as the first time-frequency resource, thereby performing the following steps S202 to S204:

S202: The terminal determines that the RLM-RS resource/RRM-RS resource (such as the first time-frequency resource) has an association relationship with the second reference signal resource (such as the second time-frequency resource) according to the received indication information. The second time-frequency resource is a time-frequency resource occupied by a second reference signal configured by the network device to the terminal. The first time-frequency resource and the second time-frequency resource do not overlap.

The second time-frequency resource in step S202 may be any second time-frequency resource that has an association relationship with the first time-frequency resource. For example, if the network device configures the terminal to have an association relationship between the RLM-RS1 resource and the second reference signal 1 to 2 resources, and the time-frequency resource occupied by RLM-RS1 is the first time-frequency resource, then, in S202 The second time-frequency resource described may be: the time-frequency resource occupied by the second reference signal 1 or the time-frequency resource occupied by the second reference signal 2.

As an example, both the first time-frequency resource and the second time-frequency resource occupy an unlicensed frequency band.

It is understandable that, in this embodiment, S202 is completed in the information processing stage as an example for description. Alternatively, S202 can be completed in the configuration phase. For example, after receiving the above-mentioned indication information, the terminal determines and stores each group of reference signal resources having an association relationship, and directly uses the association relationship in the information processing stage.

S203: The terminal obtains the received power of the first reference signal mapped on the first time-frequency resource, and the received power of the second reference signal mapped on the second time-frequency resource. Specifically, this step may be performed by the L1 layer (ie, the physical layer) of the terminal.

The first reference signal is a signal that is actually received by the terminal and mapped on the first time-frequency resource. It is understandable that although the first time-frequency resource is the time-frequency resource occupied by a RLM-RS/RRM-RS configured to the terminal by the network device, in fact, if the LBT detection is successful in S201, the network device The RLM-RS/RRM-RS will be sent on the first time-frequency resource. Therefore, the first reference signal received by the terminal on the first time-frequency resource is the RLM-RS/RRM-RS. If the LBT detection fails in S201, the network device will not send RLM-RS/RRM-RS on the first time-frequency resource. Therefore, the first reference signal received by the terminal on the first time-frequency resource is not RLM-RS /RRM-RS, it may be some interference or noise.

The embodiment of the present application does not limit which parameter is used to characterize (or evaluate) the received power of the reference signal. For example, the parameter used to characterize (or evaluate) the received power of the reference signal may include: the current measurement time reference signal reception Signal energy, strength, power, reference signal received power (RSRP), reference signal received quality (RSRQ), received signal strength indication (RSSI) or physical layer It is used to calculate the signal-to-noise and interference ratio (SINR) and so on for calculating the bit error rate (BER).

The unit of the received power of the first reference signal and the received power of the second reference signal may be one of dBm, dB, or w. But in comparison, the unit needs to be unified.

S204: The terminal determines whether the network device has sent the RLM-RS/RRM-RS on the first time-frequency resource according to the received power of the first reference signal and the received power of the second reference signal. If yes, it means that the LBT detection is successful when S201 is executed. If not, it means that the LBT detection fails when S201 is executed. specific:

If a first time-frequency resource corresponds to a second time-frequency resource (ie one-to-one), that is, there is an association relationship between the first time-frequency resource and a second time-frequency resource, the terminal can directly The received power of the reference signal and the received power of the second reference signal determine whether the network device has sent the RLM-RS/RRM-RS on the first time-frequency resource.

For example, if the difference between the received power of the first reference signal and the received power of the second reference signal is greater than or equal to the third threshold, it is determined that the network device has transmitted the RLM-RS/RRM-RS on the first time-frequency resource; otherwise, It is determined that the network device does not send RLM-RS/RRM-RS on the first time-frequency resource. This example may be applicable to a scenario where the transmission power of the second reference signal is small, for example, the transmission power of the ZP-CSI-RS is equal to zero. In this scenario, if the network device sends RLM-RS/RRM-RS on the first time-frequency resource, the received power of the first reference signal (that is, the RLM-RS/RRM-RS) obtained by the terminal is usually larger , This will make the received power of the first reference signal differ greatly from the received power of the second reference signal; if the network device does not send RLM-RS/RRM-RS on the first time-frequency resource, the terminal obtains the first The received power of the reference signal (such as noise, etc.) is usually small, which makes the received power of the first reference signal and the received power of the second reference signal not much different. Based on this, it is proposed to compare the "difference between the received power of the first reference signal and the received power of the second reference signal" with a threshold (that is, the third threshold) to determine whether the network device transmits on the first time-frequency resource. The technical scheme of RLM-RS/RRM-RS was adopted.

If one first time-frequency resource corresponds to multiple second time-frequency resources (that is, one-to-many), that is, there is an association relationship between the first time-frequency resource and multiple second time-frequency resources, the terminal can first The received power of each second reference signal received on the multiple second time-frequency resources is processed (such as smoothing processing or averaging processing, etc.), and the network is determined based on the received power of the first reference signal and the power obtained after processing. Whether the device has sent RLM-RS/RRM-RS on the first time-frequency resource.

For example, if the difference between the received power of the first reference signal and the power obtained after the processing is greater than or equal to the third threshold, it is determined whether the network device has transmitted the RLM-RS/RRM-RS on the first time-frequency resource; otherwise, It is determined that the network device does not send RLM-RS/RRM-RS on the first time-frequency resource.

It is understandable that, since "multiple first time-frequency resources correspond to one second time-frequency resource (ie many-to-one)", it can be obtained by combining multiple "one-to-one" relationships. Therefore, in this case, execute In S204, for any one of the first time-frequency resources, a technical solution based on the above-mentioned "one-to-one" can be referred to. Similarly, since “many-to-many” can be obtained by combining multiple “one-to-many” relationships, in this case, when S204 is executed, for any one of the first time-frequency resources, reference may be made based on the above-mentioned “many-to-many” relationship. One-to-one technical solution.

The following describes the technical solutions provided in the embodiments of the present application based on RRM measurement and RLM measurement respectively:

When applied to RRM measurement, in an implementation manner, the above S204 is executed by the L1 layer of the terminal. Based on this, the L1 layer of the terminal may report the received power of the first reference signal to the L3 layer (that is, the RRC layer) of the terminal after determining that the network device has sent the RRM-RS on the first time-frequency resource. Subsequently, the L3 layer of the terminal may perform RRM calculation (or RRM statistics) based on the received power of the first reference signal. The L1 layer of the terminal may not report the received power of the first reference signal to the L3 layer of the terminal after determining that the network device has sent the RRM-RS on the first time-frequency resource. In this way, the received power used by the L3 layer of the terminal to perform the RLM calculation/RRM calculation is the received power of the RRM-RS configured by the network device, which helps to improve the accuracy of the RRM-RS measurement result compared with the prior art. Compared with the prior art, this implementation improves the reporting mechanism of the L1 layer of the terminal in the RRM measurement.

When applied to RRM measurement, in another implementation manner, S204 is performed by the L3 layer of the terminal. Based on this, when the L3 layer of the terminal determines that the RRM measurement based on the first reference signal is a valid RRM measurement (equivalent to the network device sending the RRM-RS on the first time-frequency resource), it can base this time on the first reference signal. The received power of the reference signal is used for RRM calculation, for example, the RSRP is obtained based on the received power of the first reference signal. Optionally, the L3 layer of the terminal may change the last RRM measurement when it determines that the measurement based on the first reference signal is not a valid RRM measurement (equivalent to the network device not sending RRM-RS on the first time-frequency resource) The obtained RRM calculation result is used as the RRM calculation result of this RRM measurement. For example, the calculation method of the filter used for RRM calculation of the L3 layer of the terminal may be as follows:

if RP≥P ₀

F _n =(1-α)F _n-1 +αM _n

elseif RP＜P ₀

F _n ＝F _n-1

end

Where, P represents the received power of the first reference signal. If the first time-frequency resource corresponds to a second time-frequency resource, R represents the received power of the second reference signal mapped on the second time-frequency resource; if the first time-frequency resource corresponds to multiple second time-frequency resources, then R represents the power obtained after processing (such as smoothing processing or averaging processing) of the received power of each second reference signal mapped on the multiple second time-frequency resources. P ₀ represents the third threshold. F _n represents the RSRP/RSRQ/RSSI calculated at the nth time, and F _n-1 represents the RSRP/RSRQ/RSSI calculated at the n-1th time. α is a parameter in smoothing filtering, which can be called the forgetting factor. M _n represents the value obtained this time. For example, if the RRM measurement is specifically an RSRP measurement, _{the value of M n} may be equal to the value of P.

It should be noted that when RP<P ₀ , _{the calculation formula of F n} can also be replaced with other formulas, which is not limited in the embodiment of the present application.

In addition, for comparison, here is the calculation formula for the filter used in the current protocol for the L3 layer of the current terminal for RRM calculation:

F _n =(1-α)·F _n-1 +α·M _n.

The explanation of the relevant parameters in the formula can refer to the above.

Compared with the prior art, this implementation modifies the calculation formula of the filter used for the RRM calculation at the L3 layer of the terminal, which helps the wireless communication system to better adapt to the unlicensed frequency band and improve the flexibility of the system. It is understandable that, in this implementation manner, the method may further include: after performing S203, the L1 layer of the terminal reports the received power of the first reference signal and the received power of the second reference signal to the L3 layer.

When applied to RLM measurement, after performing the above S201-S204, the terminal can trigger the change of the RLM or RLF related counter after determining that the network device has sent the RRM-RS on the first time-frequency resource; and after determining that the network device is in the first time-frequency resource After the RRM-RS is not sent on the time-frequency resource, the measurement result of this time is ignored, that is, the change of the RLM or RLF-related counter is not triggered.

In the technical solution provided by the embodiment of the present application, the second reference signal is introduced, so that the terminal can determine whether the network device has sent the RLM-RS/RRM-RS on the corresponding time-frequency resource through the received power of the second reference signal. This is a technical solution provided in consideration of the following factors: since the network equipment transmits RLM-RS/RRM-RS and does not transmit RLM-RS/RRM-RS on the same time-frequency resource, the terminal is at that time The received power of the reference signal (ie, the first reference signal) received on the frequency resource is different. Therefore, using the received power of the second reference signal as a reference and performing the same operation with the different received power, different results will be obtained. Based on this, by pre-defining one or more operating rules between the received power of the second reference signal and the received power of the first reference signal, it is possible to deduce whether the first reference signal is RLM-RS/RRM-RS, That is, it is determined whether the network device sends the RLM-RS/RRM-RS on the first time-frequency resource.

In addition, because in this technical solution, when performing RLM measurement/RRM measurement, the terminal can autonomously determine whether the network device has sent RLM-RS/RRM-RS on the configured corresponding time-frequency resource, without the participation of the network device. . Therefore, it helps to improve the flexibility of the communication system. In addition, after the terminal determines whether the network device has sent RLM-RS/RRM-RS on the configured corresponding time-frequency resources, it can further determine whether to use the received power of the first reference signal for RLM calculation/RRM calculation. Therefore, there is Helps improve the accuracy of RLM calculation/RRM calculation results.
