In order to better understand the schemes of the embodiments of the present application, technical terms related to the embodiments of the present application are described below.

1) And the CSI-RS is used for realizing the functions of channel state measurement, beam management, time frequency offset tracking, mobility management and rate matching.

The method is characterized in that a non-zero power channel state information reference signal (non-zero-power CSI-RS, NZP-CSI-RS) is used for measuring channel states, a network device can configure one or more NZP-CSI-RS resource sets for the terminal device through radio resource control (radio resource control, RRC) signaling, and the terminal device measures and reports NZP-CSI-RS resources contained in the NZP-CSI-RS resource sets. The channel state information (channel state information, CSI) measured and reported by the terminal device includes, but is not limited to, one or more of the following: channel quality indication (Channel Quality Indicator, CQI), precoding matrix (precoding matrix indicator, PMI), CSI-RS resource indication (CSI-RS resource indicator, CRI), synchronization signal and physical broadcast channel (physical broadcast channel, PBCH) block (synchronization Signal and PBCH block, SSB) resource indication (SBB resource indicator, SSBRI), layer indication (layer indicator, LI), rank Indication (RI), layer1reference signal received power (layer 1reference signal receiving power, L1-RSRP), layer1 signal to interference plus noise ratio (layer 1 signal to interference plus noise ratio, L1-SINR), or Capability Set Index (Capability [ Set ] Index).

Each NZP-CSI-RS resource set contains one or more NZP-CSI-RS resources, and each NZP-CSI-RS resource can be configured with a maximum of 32 ports and mapped to one or more symbols. The NZP-CSI-RS resources can be configured through high-level parameters NZP-CSI-RS-Resource, CSI-Resource eConfig and NZP-CSI-RS-Resource set, and specific configuration information comprises but is not limited to the following information:

NZP-CSI-RS-resource eid: ID of NZP CSI-RS resource;

scramblingID: scrambling code ID generated by CSI-RS sequence;

periodic AndOffset: the period and offset values of the periodic CSI-RS;

qcl-InfoPeriodacCSI-RS: indicating quasi co-location (QCL) relation of periodic CSI-RS.

2) QCL, a large scale parameter of a channel experienced by a symbol on one antenna port, can be inferred from the channel experienced by a symbol on another antenna port. The large scale parameters of the channel include, but are not limited to, delay spread, average delay, doppler spread, doppler shift, average gain, and spatial reception parameters. QCL includes the following types (types):

QCL-type a: doppler shift, doppler spread, average delay, delay spread;

QCL-type B: doppler shift, doppler spread;

QCL-type C: doppler shift, average delay;

QCL-type D: spatial reception parameters (mainly for the 6G or higher frequency band).

The general transmission configuration indication (transmission configuration indicator, TCI) state represents QCL reference information, the TCI state structure comprising: DL Reference RS1 QCL Type 1,DL Reference RS2|QCL Type 2. Each TCI state contains configuration parameters of QCL relationships between demodulation Reference signal (demodulation Reference signal, DMRS) ports of one or more downlink Reference signals (downlink Reference signal, DL Reference RS) and physical downlink shared channel (physical downlink shared channel, PDSCH), DMRS ports of physical downlink control channel (physical downlink control channel, PDCCH), or CSI-RS ports of CSI-RS resources. DMRS ports, e.g., PDSCH, may obtain QCL information for Type a and Type D from tracking reference signals (tracking reference signal, TRS) and beam-managed CSI-RS. If a TCI state includes two QCL-types, the two QCL-types are typically different.

3) TRS is one of periodic NZP CSI-RS. In a high-speed rail scenario, the terminal device uses TRS to perform time-frequency offset tracking, which is generally a NZP CSI-RS resource with density of 3 and 1 port, and a TRS symbol interval in one slot is 4. For the low frequency band, the higher layer may configure the UE with one or more NZP CSI-RS sets, each set of NZP CSI-RS resources containing 4 periodicity of NZP CSI-RS resources, the 4 NZP CSI-RS resources being distributed over two consecutive time slots, each time slot containing two periodicity of NZP CSI-RS resources, and the positions of the NZP CSI-RS resources in the two time slots being the same in the time domain. For the high-band, the high layer configures one or more NZP CSI-RS sets for the UE, each NZP CSI-RS resource set comprising two periodic NZP CSI-RS resources distributed over 1 slot, or 4 periodic NZP CSI-RS resources distributed over two consecutive slots, each slot comprising two periodic NZP CSI-RS resources, and the positions of the NZP CSI-RS resources in the two slots are the same in the time domain.

4) The terms "system" and "network" in embodiments of the present application may be used interchangeably. The term "plurality" means two or more, and in view of this, the term "plurality" may also be understood as "at least two" in the embodiments of the present application. "at least one" may be understood as one or more, for example as one, two or more. For example, including at least one means including one, two or more, and not limiting what is included, e.g., including at least one of A, B and C, then A, B, C, A and B, A and C, B and C, or A and B and C, may be included. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/", unless otherwise specified, generally indicates that the associated object is an "or" relationship. In addition, unless specified to the contrary, the embodiments of the present application may refer to "first," "second," etc. ordinal numbers for distinguishing between a plurality of objects and not to limit a sequence, timing, priority, or importance of the plurality of objects.

In order to facilitate understanding of the embodiments of the present application, a description is given next of a deployment scenario of a high-speed rail DPS applicable to the present application, where the network architecture and the service scenario described in the embodiments of the present application are for more clearly describing a technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided by the embodiments of the present application, and as a person of ordinary skill in the art can know that, with the appearance of a new service scenario, the technical solution provided by the embodiments of the present application is applicable to similar technical problems.

In a high-speed rail DPS scenario, in order to save the overhead of CSI-RS, CSI-RS is often transmitted by a specific transmission and reception point (transmission reception point specific, TRP specific), that is, a network device configures a common CSI-RS resource set for all terminal devices in a cell, each TRP transmits several CSI-RS resources in the CSI-RS resource set, and when a terminal device establishes a QCL relationship with a TRS transmitted by a certain TRP, other TRPs also transmit corresponding CSI-RS resources. As shown in fig. 2, the network device configures 6 common CSI-RS resources, and the 6 CSI-RS resources are shared by all terminal devices in the cell, and there are 3 TRPs in the cell, each TRP transmits 2 CSI-RS resources, and when the terminal device and TRP0 communicate with each other, TRP1 and TRP2 also transmit corresponding CSI-RS resources.

The terminal device performs measurement and reporting according to the CSI-RS resources issued by the TRP, but the maximum number of NZP CSI-RS resources that the terminal device supports simultaneous measurement and the maximum number of CSI reports (reports) that are simultaneously reported are limited. At present, the most NZP CSI-RS resources which can be measured simultaneously by the terminal equipment are 1 or 2, and the CSI report which can be reported simultaneously is 1.

Although there are different terminal devices supporting simultaneous resource measurement and reporting in the network, CSI-RS resources are sometimes transmitted according to cell level or TRP level in order to save CSI-RS resource overhead and facilitate network deployment. In the high-speed rail DPS scenario, in order to compatibly support terminal devices with 1 number of simultaneous resource measurements and reporting, there are several possible deployment schemes:

deployment scheme one: the network device configures a set of periodic CSI-RS resources at a Cell level, and as shown in fig. 3, all TRPs belonging to one Cell simultaneously transmit a set of identical CSI-RS resources to the terminal device.

For the terminal equipment, since all TRPs transmit the same CSI-RS resource, the measurement result measured and reported by the terminal equipment is the comprehensive result of the CSI-RS resources transmitted by all TRPs, and the state of the current transmission and reception data channels of the terminal equipment cannot be accurately reflected, so that the downlink demodulation performance is reduced.

Deployment scheme II: as shown in fig. 4, different TRPs configure different periodic CSI-RS resources through RRC reconfiguration messages.

In the moving process of the terminal equipment, along with TRP or TCI switching, different TRPs reconfigure different CSI-RS resources for the terminal equipment, so that the measurement result measured and reported by the terminal equipment is matched with the current downlink data receiving channel.

However, in the DPS scene of high-speed rail, the terminal device moves fast and frequently switches the TRP, the network device configures different periodic CSI-RS resources for the terminal device through the RRC reconfiguration command of the terminal device level, which causes a great amount of high-layer signaling overhead, and the effective time is slower, so that the downlink demodulation performance is affected in the DPS scene.

In the deployment scheme, the terminal equipment can measure and report all periodic CSI-RS resources configured by the network equipment, but the number of simultaneous resource measurement and reporting by the terminal equipment may be limited, and may be less than the number of all periodic CSI-RS resources configured by the network equipment, so that the measurement result reported by the terminal equipment is inaccurate, and the downlink demodulation performance is affected. Accordingly, an embodiment of the present application provides a measurement resource indicating method, and fig. 5 is a schematic diagram of a measurement resource indicating method, including the following steps:

S501: the network equipment sends the first indication information, and correspondingly, the terminal equipment receives the first indication information.

The first indication information is used for indicating the terminal equipment to measure and report L periodic reference signal resources, wherein L is an integer greater than or equal to 1. For example, the first indication information may include higher layer or physical layer signaling, in particular, the first indication information includes, but is not limited to, MAC CE and/or DCI commands.

The Periodic reference signal resource is, for example but not limited to, a Periodic CSI-RS (Periodic CSI-RS or P-CSI-RS) resource.

By way of example, the network device may be, but is not limited to, a particular TRP of an access network device (or base station).

S502: and the terminal equipment measures and reports the L periodic reference signal resources, and correspondingly, the network equipment receives the measurement results of the L periodic reference signal resources.

In the method, the network equipment instructs the terminal equipment to measure and report the L periodic reference signal resources through the first instruction information, the terminal equipment can measure and report a certain number of periodic reference signal resources according to the dynamic instruction of the network equipment, and the terminal equipment does not measure and report all periodic channel resources configured by the network equipment, so that the accuracy of a measurement result reported by the terminal can be improved, the downlink demodulation performance is improved, the accuracy of downlink scheduling is further improved, and the downlink throughput is improved.

In one possible implementation, the value of L is related to the number of resources supported by the terminal device to be measured and reported simultaneously, so that the terminal device with limited number of resources to be measured and reported is supported to measure and report the periodic reference signal resources, and the accuracy of the measurement result is further improved. For example, L is less than or equal to K, K is an integer greater than or equal to 1, and K represents the number of periodic reference signal resources which are supported by the terminal equipment at most for measurement and reporting. If the number of resources supported by the terminal equipment to be measured simultaneously is different from the number of resources reported simultaneously, the minimum value in the two numbers can be used as the number K of the periodic reference signal resources supported by the terminal equipment to be measured and reported at most. For example, the maximum number of periodic reference signal resources supported by the terminal device is determined (e.g. 1 or 2) by the most configured periodic NZP-CSI-RS resources (maxconfignnumbernzp-CSI-RS-PerCC) supported by each carrier of the higher layer parameters, and the maximum number of measurement results of the periodic reference signal resources supported by the terminal device and reported at the same time is determined (e.g. 1) by the most reported periodic NZP-CSI-RS resources (maxconnumberperiodic CSI-PerBWP-ForCSI-Report) supported by each BWP of the higher layer parameters, then the number K of periodic reference signal resources supported by the terminal device and reported at the most is 1.

Optionally, when K is less than or equal to M, the first indication information is used to instruct the terminal device to measure and report L periodic reference signal resources, M is an integer greater than or equal to 1, and M represents the number of periodic reference signal resources configured by the network device for the terminal device. That is, when the number of periodic parameter signal resources configured by the network device for the terminal device exceeds the number of periodic reference signal resources that the terminal device supports measurement and reporting at most, the network device instructs the terminal device to measure and report the L periodic reference signal resources through the first indication information, so as to support the terminal device with limited number of measurement and reporting resources to measure and report the periodic reference signal resources. Wherein, for a plurality of periodic reference signal resources, at least one of time domain resources, frequency domain resources and code domain resources are different among different periodic reference signals. If the same time-frequency domain resource positions are configured for different periodic reference signals, but different code domain resources are configured, the resource overhead can be further reduced. When the network device configures the periodic reference signal resource for the terminal device, the periodic reference signal resource may be configured by using a higher layer signaling, including but not limited to RRC signaling.

When the first indication information indicates the terminal device to measure and report the L periodic reference signal resources, the following manner may be adopted to indicate:

mode one: implicit indication means.

The first indication information is used for indicating the terminal equipment to measure and report the L periodic reference signal resources corresponding to the activated L TCI state IDs. In one implementation, the first indication information is an activation command for transmitting configuration indication status identifiers (transmission configuration indication state identifier, TCI state IDs), for example, the first indication information is used for indicating that L TCI state IDs are activated, and the TCI state IDs are associated with periodic reference signal resources, that is, the first indication information indicates, by indicating the L TCI state IDs that are activated, that the terminal device measures and reports the L periodic reference signal resources. The first indication information may be a defined activation signaling, such as TCI States Activation for UE-specific PDSCH MAC CE and/or Transmission Configuration Indication) command, or a newly added activation signaling.

In this manner, when the terminal device measures the L periodic reference signal resources in S502, a channel characteristic parameter may be obtained according to the reference signal resources corresponding to the activated L TCI state IDs, and the L periodic reference signal resources corresponding to the activated L TCI state IDs may be measured and reported according to the channel characteristic parameter. That is, in this manner the periodic reference signal resource and the reference signal resource are associated by the corresponding TCI state ID. Wherein the reference signal includes, but is not limited to, one or more of a tracking reference signal (tracking reference signal, TRS), or a synchronization reference signal (synchronization signal and physical broadcast channel (physical broadcast channel, PBCH) block (synchronization signal and PBCH block, SSB)), and the channel characteristic parameter includes, but is not limited to, a channel time frequency offset characteristic.

In some cases, the number M of periodic reference signal resources configured by the network device for the terminal device is equal to or less than N, where N represents the number of reference signal resources configured by the network device for the terminal device, where each of the M periodic reference signal resources is associated with at least one of the N reference signal resources, and each of the reference signal resources is associated with one TCI state ID. In general, if m=n, each periodic reference signal resource is associated with one reference signal resource, and if M < N, each periodic reference signal resource is associated with more than two reference signal resources, both of which are described below. When the network device configures the reference signal resource for the terminal device, the reference signal resource may be configured by using a higher layer signaling, including but not limited to RRC signaling.

For example, in the DPS scenario, it is assumed that the network device configures N TRS resources (only for example, but also for SSB and other reference signal resources) for the terminal device, where each TRS resource is associated with one TCI state ID, and then the network device further configures M P-CSI-RS resources (only for example, but also for other periodic reference signal resources) for the terminal device. The network device may configure the P-CSI-RS resources at the TRP level, and instruct the terminal device to measure and report only the L P-CSI-RS resources therein by presetting some constraints.

In the case of m=n, each P-CSI-RS resource is associated with one TRS resource by one TCI state ID, i.e., the TCI state ID corresponding to the QCL information of each P-CSI-RS resource is the same as the TCI state ID of its corresponding TRS resource. For example, there may be a constraint that if a terminal device only supports measurement of one CSI-RS resource at maximum, for example, the reporting capability maxConfigNumberNZP-CSI-RS-PerCC of the terminal device is 1, the terminal device measures and reports the P-CSI-RS resource corresponding to the activated TCI state ID.

In the case of M < N, each P-CSI-RS resource is configured with greater than or equal to 1 TCI state ID. The association relationship may satisfy: TCI is associated with different P-CSI-RS resources at the corresponding TCI state ID before and after one switching. If the terminal device is activated with one TCI state ID (possibly corresponding to TCI before or after switching), the terminal device measures and reports the P-CSI-RS resource corresponding to the one TCI state ID.

When M < N, as shown in fig. 6, one possible scenario is that the network device configures QCL relationships of 6 TRS resources, and TCI state IDs corresponding to the 6 TRS resources are 1 to 6 respectively. The network device is configured with 2P-CSI-RS resources, wherein QCL information in CSI-RS1 of the P-CSI-RS resources corresponds to TCI state IDs 1,3 and 5 (corresponding to TRSs 1,3 and 5, respectively), and QCL information in CSI-RS2 of the P-CSI-RS resources corresponds to TCI state IDs 2,4 and 6 (corresponding to TRSs 2,4 and 6, respectively). In the moving process of the terminal equipment, the switching sequence of TRS resources/TCI state is as follows: 1- >2- >3- >4- >5- >6, and the sequence of measuring and reporting the P-CSI-RS resources by the corresponding terminal device is as follows: 1- >2- >1- >2- >1- >2. In fig. 6, if the TCI state ID corresponding to UE1 is 2, UE1 measures and reports P-CSI-RS resource 2, and if the TCI state ID corresponding to UE2 is 5, UE2 measures and reports P-CSI-RS resource 1.

When M < N, as shown in fig. 7, one possible scenario is that the network device configures QCL relationships of 6 TRS resources, and TCI state IDs corresponding to the 6 TRS resources are 1 to 6, respectively. The network device is configured with 3P-CSI-RS resources, wherein QCL information in CSI-RS1 of the P-CSI-RS resources corresponds to TCI state IDs 1 and 3 (corresponding to TRSs 1 and 3, respectively), QCL information in CSI-RS2 of the P-CSI-RS resources corresponds to TCI state IDs 2,4 and 6 (corresponding to TRSs 2,4 and 6, respectively), and QCL information in CSI-RS2 of the P-CSI-RS resources corresponds to TCI state ID 5 (corresponding to TRS 5, respectively). In the moving process of the terminal equipment, the switching sequence of TRS resources/TCI state is as follows: 1- >2- >3- >4- >5- >6, and the sequence of measuring and reporting the P-CSI-RS resources by the corresponding terminal device is as follows: 1- >2- >1- >2- >3- >2. In fig. 7, if the TCI state ID corresponding to UE1 is 2, UE1 measures and reports P-CSI-RS resource 2, and if the TCI state ID corresponding to UE2 is 5, UE2 measures and reports P-CSI-RS resource 3.

Mode two: explicit indication means.

The first indication information is used to indicate one or more of a periodic reference signal Resource identity (e.g., resource ID), or a periodic reference signal Resource Set identity (e.g., resource Set ID), or a scrambling code identity of the periodic reference signal Resource. For example, if the parameters other than the scrambling code are the same between the periodic reference signals, the first indication information is used to indicate the scrambling code identification of the periodic reference signals.

Alternatively, the first indication information may include, but is not limited to, MAC CE or DCI, that is, when TRP is switched, the network device may dynamically indicate, by the MAC CE or DCI, the periodic reference signal resource measured and reported by the terminal device. Taking the above fig. 6 as an example, the network device may instruct the UE1 to measure and report the P-CSI-RS resource 2 through the MAC CE or DCI, and instruct the UE2 to measure and report the P-CSI-RS resource 1 through the MAC CE or DCI.

Based on the same technical concept as the measurement resource indication method described above, the embodiment of the present application also provides a communication system, as shown in fig. 8, where the communication system 800 includes a network device 801 and a terminal device 802. The network device 801 and the terminal device 802 may implement the method described in the above method embodiments.

For example, the network device 801 is configured to send first indication information, where the first indication information is used for the terminal device 802 to measure and report L periodic reference signal resources, where L is an integer greater than or equal to 1;

the terminal device 802 is configured to receive the first indication information, measure and report L periodic reference signal resources;

the network device 801 is further configured to receive measurement results of the L periodic reference signal resources.

In one implementation, when K is less than or equal to M, the first indication information is used to instruct the terminal device 802 to measure and report L periodic reference signal resources, where L is less than or equal to K, K, M is an integer greater than or equal to 1, M represents the number of periodic reference signal resources configured by the network device 801 for the terminal device 802, and K represents the number of periodic reference signal resources that the terminal device 802 supports measurement and reporting at most.

In one implementation, the first indication information includes a MAC CE or DCI.

In one implementation, the first indication information is used to instruct the terminal device 802 to measure and report L periodic reference signal resources corresponding to the activated L transmission configuration indication status identifiers TCI state ID.

In one implementation, the terminal device 802 is specifically configured to obtain a channel characteristic parameter according to the reference signal resource corresponding to the activated L TCI state IDs; and measuring and reporting the L periodic reference signal resources corresponding to the activated L TCI state IDs according to the channel characteristic parameters.

In one implementation, M.ltoreq.N, N represents the number of reference signal resources configured by the network device 801 for the terminal device 802, each of the M periodic reference signal resources being associated with at least one of the N reference signal resources, each reference signal resource being associated with one TCI state ID.

In one implementation, the first indication information is used to indicate a periodic reference signal resource identity, or a periodic reference signal resource set identity, or a scrambling code identity of a periodic reference signal resource.
