technical field

The present application belongs to the field of communication technologies, and in particular relates to a method, apparatus and device for reporting signal parameters.

Background technique

Under the network deployment of a single frequency network (SFN), a base band unit (BBU) can be connected to multiple remote radio heads (RRH), that is, multiple sending and receiving points ( transmitting receiving point, TRP). In this way, user equipment (UE) does not need to frequently switch base stations during high-speed movement.

In the SFN transmission scenario, multiple TRPs in the network can simultaneously transmit the same data to the UE. However, since the positional relationship between the UE and the multiple TRPs is different, the power, time delay, phase and Doppler frequency shift of the transmission signals of the multiple TRPs reaching the UE may be different. For example, when the delays of the SFN signals from the two TRPs to the UE are the same, the SFN signals may be cancelled; when the delays of the SFN signals from the two TRPs to the UE are large, the SFN signals may appear serious Deep fading in the frequency domain: When the UE moves at high speed between two TRPs, it will cause two Doppler frequency offsets with opposite signs in the received signal, resulting in deep fading in the time domain of the SFN signal.

To sum up, how to improve the data transmission performance in the SFN transmission scenario has become an urgent problem to be solved.

The method for reporting signal parameters provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

As shown in FIG. 2 , an embodiment of the present application provides a method for reporting signal parameters. The method can be applied to the above wireless communication system, and the method can include the following steps 201 to 203 .

Step 201: The UE measures signal parameters of multiple TRP transmission signals through at least one reference signal resource set.

The at least one reference signal resource set may be configured by the network device to the UE through CSI resource setting (resource setting), and the multiple TRPs may be TRPs that transmit signals to the UE.

It should be noted that the above-mentioned multiple TRPs may be multiple TRPs for transmitting signals to the UE in the SFN transmission scenario.

Optionally, the type of one reference signal resource set (any reference signal resource set in the above at least one reference signal resource set) is any of the following:

Tracking reference signal (TRS);

Non-TRS non-zero power channel state information reference signal (non-zero power CSI reference signal, NZP-CSI-RS);

Synchronization signal and physical broadcast channel block (SSB);

Positioning reference signal (positioning reference signal, PRS).

Optionally, in this embodiment of the present application, in the case that the above at least one reference signal resource set is M reference signal resource sets (M is an integer greater than 1), the types of the M reference signal resource sets may be the same, or the types of the M reference signal resource sets may be the same. It may be different, and may be specifically determined according to actual usage requirements, which is not limited in this embodiment of the present application.

That is to say, the types of the above M reference signal resource sets can be any one of TRS, non-TRS NZP-CSI-RS, SSB and PRS, or can be TRS, non-TRS NZP-CSI-RS, SSB and any combination of PRS.

Optionally, in one measurement of the signal parameters of the above-mentioned multiple TRP transmission signals, if the reference signal resource sets for measuring the signal parameters of the multiple TRP transmission signals are of the same type, then the signal parameters of the multiple TRP transmission signals are measured. The pilot patterns of the reference signal resource sets are the same.

Optionally, in one measurement of the signal parameters of multiple TRP transmission signals, if the reference signal resource sets for measuring the signal parameters of the multiple TRP transmission signals are of the same type, the reference signal resource sets for measuring the signal parameters of the multiple TRP transmission signals are of the same type. The pilot patterns of the reference signal resources in the signal resource set are the same.

Optionally, when the type of the reference signal resource set is the above-mentioned non-TRS NZP-CSI-RS, the frequency domain density (density) of the non-TRS NZP-CSI-RS is a first value (denoted as Y) , the number of ports (ports) of the non-TRS NZP-CSI-RS is the second numerical value (denoted as Z).

It can be understood that when the type of the reference signal resource set is a non-TRS NZP-CSI-RS, the frequency domain density of the NZP-CSI-RS resources in the NZP-CSI-RS resource set is the above-mentioned first value, and/or , the port number of the NZP-CSI-RS resource is the second value.

Exemplarily, the above-mentioned first numerical value may be 3, that is, Y=3, and the above-mentioned second numerical value may be 1, that is, Z=1. Of course, in actual implementation, the first value and the second value may also be any other possible values, which may be specifically determined according to actual usage requirements, which are not limited in the embodiments of the present application.

Optionally, in one measurement of signal parameters of multiple TRP transmission signals, the time domain interval of reference signal resources or resource sets for measuring signal parameters of different TRP transmission signals is smaller than the first threshold.

In the embodiment of the present application, in the case where the reference resources for measuring the signal parameters of different TRP transmission signals are reference resources in the same reference signal resource set, in one measurement of the signal parameters of multiple TRP transmission signals, the measurement of different TRP transmission signals The time domain interval of the reference signal resources of the signal parameter of the signal is smaller than the first threshold.

Exemplarily, taking two TRPs (respectively TRP1 and TRP2) as an example, it is assumed that the NZP-CSI-RS1 resource is sent from TRP1, the NZP-CSI-RS2 and NZP-CSI-RS3 resources are sent from TRP2, and the above first value is is 5 symbols, that is, X=5 symbols, then as shown in Figure 3, the time domain interval between NZP-CSI-RS1 and NZP-CSI-RS2 is 2 symbols, that is, NZP-CSI-RS1 and NZP -The time domain interval of CSI-RS2 satisfies the condition of less than 5 symbols, so it can be used to measure the signal parameters in the same CSI report; while the time domain interval of NZP-CSI-RS1 and NZP-CSI-RS3 is greater than 5 symbols , does not meet the conditions, so the network device can avoid delivering this configuration.

In the embodiment of the present application, in the case where the reference resources for measuring signal parameters of different TRP transmission signals are reference resources in different reference signal resource sets, in one measurement of the signal parameters of multiple TRP transmission signals, the different TRP transmission signals are measured in one measurement. The time domain interval of the reference signal resource set of the signal parameter is smaller than the first threshold.

In the embodiment of the present application, the above-mentioned time domain interval of the reference resource sets for measuring signal parameters of different TRP transmission signals refers to the time domain interval between the first resources of different reference signal resource sets. Taking the reference signal resource sets (that is, two reference signal resource sets) for measuring signal parameters of two TRP transmission signals as an example, the time domain interval of the two reference signal resource sets may be: the first reference signal resource set in one reference signal resource set The time-domain interval between a resource and the first resource in another reference signal resource set.

Exemplarily, taking two TRPs (respectively TRP1 and TRP2) as an example, it is assumed that the TRS1 resource set is sent from TRP1, the TRS2 resource set is sent from TRP2, and the TRS1 resource set and the TRS2 resource set belong to different CSI resource configurations (CSI resource sets respectively). resource setting), and the first value is 5 symbols (that is, X=5 symbols), then as shown in Figure 4, since the time domain interval between the TRS1 resource set and the TRS2 resource set is 2 symbols, so shown in Figure 4 The configuration mode can be a qualified configuration mode.

Optionally, in the embodiment of the present application, the CSI resource configuration (CSI resource setting) and the CSI report configuration (CSI report setting) may have different associations. The following three possible implementations are used to configure the CSI resource configuration and the CSI report configuration. The relationship between them is exemplified.

The first possible implementation: in the case that the reference signal resource sets for measuring the signal parameters of multiple TRP transmission signals belong to different CSI resource configurations, different CSI resource configurations (CSI resource setting) and the same CSI report configuration (CSI report setting) has an associated relationship.

The second possible implementation manner: when the reference signal resource sets for measuring the signal parameters of multiple TRP transmission signals belong to different CSI resource configurations, the different CSI resource configurations are associated with different CSI reporting configurations.

The third possible implementation manner: in the case that the reference signal resource sets for measuring signal parameters of multiple TRP transmission signals belong to the same CSI resource configuration, the same CSI resource configuration has an associated relationship with the same CSI reporting configuration.

Optionally, in this embodiment of the present application, the CSI reporting configuration (CSI resource setting) may be associated with a periodic TRS.

Optionally, in the embodiment of the present application, when the type of the reference signal resource set includes aperiodic TRS, the CSI reporting amount configured in the CSI reporting configuration (CSI resource setting) may be none or the above-mentioned signal parameter reporting quantity.

Step 202: The UE sends signal parameter reporting information to the network device.

The above-mentioned other reporting amounts may be the existing reporting amounts in the CSI reporting configuration.

It can be understood that in the case where the network device configures multiple signal parameter reporting amounts to the UE, the network device may carry the multiple signal parameter reporting amounts in the same CSI reporting configuration and send it to the UE, or report the multiple signal parameter reporting amounts to the UE. The amount and other reported amounts can be carried in the same CSI reporting configuration and sent to the UE.

Optionally, in this embodiment of the present application, the type of the reported amount of the signal parameter may be any of the following:

the value of the signal parameter;

difference of signal parameters;

The absolute value of the difference of the signal parameters.

Optionally, in the case where the type of the signal parameter reporting amount is the value of the signal parameter, the values of the signal parameters of the above-mentioned multiple TRP transmission signals may be mapped in the same CSI report according to a preset order for reporting.

The size order of the identifier (ID) of the reference signal resource set;

The order of the numbers of the reference signal resources;

The size order of the CSI-RS resource indicator (CSI-RS resource indicator, CRI);

Exemplarily, taking two TRPs as an example, it is assumed that the preset order is the order of the reference signal resource sets from small to large, and the number of the reference signal resource sets for measuring the signal parameters of the TRP1 transmission signal is smaller than that for measuring the TRP2 transmission signal. The number of the reference signal resource set of the signal parameter, the UE can first map the value of the signal parameter of the TRP1 transmission signal in the CSI report, and then map the value of the signal parameter of the TRP2 transmission signal.

Optionally, in this embodiment of the present application, when the type of the signal parameter reporting amount is the difference value of the signal parameter:

The difference value of the above signal parameters may be the value of the signal parameter measured on the reference signal resource set with a large number, minus the value of the signal parameter measured on the reference signal resource set with a small number; or,

The difference value of the reference signal may be the value of the signal parameter measured on the reference signal resource set after the configuration sequence, minus the value of the signal parameter measured on the reference signal resource set before the configuration sequence; or,

The difference value of the above reference signal may be the value of the signal parameter measured on the reference signal resource set in the configuration order, minus the value of the signal parameter measured on the reference signal resource set in the configuration order; or,

The difference value of the above signal parameters is the value of the signal parameter measured on the reference signal resource with the small number, minus the value of the signal parameter measured on the reference signal resource with the large number; or,

The difference between the reference signals is the value of the signal parameter measured on the reference signal resource in the preceding configuration sequence, minus the value of the signal parameter measured on the reference signal resource in the configuration order.

It can be understood that the calculation method of the difference value of the above-mentioned signal parameters may be a pre-agreed (that is, predefined) calculation method. In this way, when the network device configures the type of the above-mentioned signal parameter reporting amount as the difference value of the signal parameter, the UE The difference value of the reference signal can be obtained directly through the above calculation method.

In addition, in actual implementation, the difference value of the signal parameter may also be calculated in any other possible manner, which may be specifically determined according to actual usage requirements, which is not limited in this embodiment of the present application.

Optionally, in the embodiment of the present application, when the type of the above-mentioned signal parameter reporting amount is the difference value of the signal parameter, the signal parameter reporting method provided by the embodiment of the present application may further include the following steps 204 and 205 .

Specifically, it can be determined according to actual use requirements, which is not limited in the embodiment of the present application.

In the embodiment of the present application, in the case where the type of the signal parameter reporting amount is the difference value of the signal parameter, the UE may explicitly indicate the difference between the signal parameters reported by the UE to the network device by sending the identification information of the first TRP to the network device. How the value is calculated. It can be understood that the first TRP may be a reference TRP for calculating the difference of the signal parameters.

Optionally, in this embodiment of the present application, the above-mentioned first TRP may be a TRP corresponding to a signal parameter that is used as a subtrahend or a minuend when calculating the difference between the reference signals.

Exemplarily, taking two TRPs as an example, which are TRP1 and TRP2 respectively, it is assumed that the above-mentioned first TRP is the TRP corresponding to the signal parameter of the minuend when calculating the difference of the reference signal, and the difference of the reference signal is equal to the transmission of TRP1. The value of the signal parameter of the signal is subtracted from the value of the signal parameter of the TRP2 transmission signal, then the UE can determine the TRP2 as the reference TRP (ie the first TRP), and can report the identification information of the TRP2 to the network device.

Optionally, when the type of the signal parameter reporting amount is the absolute value of the difference of the signal parameters, the signal parameter reporting method provided in this embodiment of the present application may further include the following steps 206 and 207 .

Step 206: The UE sends the identification information of the second TRP to the network device.

Step 207: The network device receives the identification information of the second TRP sent by the UE.

It should be noted that the embodiment of the present application may not limit the execution order between step 206 and the above-mentioned step 202, that is, the UE may execute step 206 before step 202, or execute step 206 after step 202, or execute steps at the same time. 202 and step 206. Specifically, it can be determined according to actual use requirements, which is not limited in the embodiment of the present application.

Optionally, the second TRP may be the TRP corresponding to the signal parameter with the smallest or largest value when the absolute value of the difference between the reference signals is calculated.

It should be noted that, in this embodiment of the present application, when the above-mentioned multiple TRPs are two TRPs (for example, TRP1 and TRP2), the above-mentioned second TRP may be the absolute value of the difference between the reference signals, and the signal of the signal transmitted by TRP1 when the absolute value of the difference is calculated. A TRP corresponding to a signal parameter with a smaller or larger value between the value of the parameter and the value of the signal parameter of the TRP1 transmission signal.

Optionally, in this embodiment of the present application, the identification information of the TRP may include any of the following:

Optionally, in the embodiment of the present application, in the case that the number of the above-mentioned signal parameter reporting amounts is multiple, the UE sends the above-mentioned signal parameter reporting information to the network device in two possible ways, namely, the first way and the second way. Method two. The two possible ways are exemplarily described below.

Manner 1: The UE multiplexes multiple signal parameter reporting information on the same reporting resource, and sends it to the network device, so that the network device can receive multiple signal parameter reporting information multiplexed by the UE on the same reporting resource.

Mode 2: The UE multiplexes multiple signal parameter reporting information and other reporting information on the same reporting resource, and sends it to the network device, so that the network device can receive multiple multiplexed multiplexed information on the same reporting resource sent by the UE. Signal parameter reporting information and other reporting information.

It should be noted that one signal parameter reporting amount may correspond to one signal parameter, that is, each signal parameter reporting information in the above-mentioned multiple signal parameter reporting information may correspond to different signal parameters respectively. In this way, after the UE measures and obtains the measurement results of the signal parameters of the multiple TRP transmission signals, the UE can package the measurement results corresponding to each signal parameter reporting amount respectively, so as to obtain multiple signal parameter reporting information. Then, the UE may multiplex the multiple signal parameter reporting information on the same reporting resource and send it to the network device, or the UE may multiplex the multiple signal parameter reporting information and other reporting information on the same reporting resource, and sent to the network device.

Optionally, in this embodiment of the present application, in the case that the above-mentioned CSI reporting configuration further includes a reporting threshold condition corresponding to the signal parameter reporting amount, the above-mentioned step 202 can be specifically implemented by the following step 202a.

Step 202a: The UE sends signal parameter reporting information to the network device under the condition that the above measurement result satisfies the reporting threshold condition.

It can be understood that after the UE obtains the measurement results of the signal parameters of the above-mentioned multiple TRP transmission signals, the UE can first determine whether the measurement results meet the above reporting threshold conditions, and if so, the UE can send the above-mentioned signal parameter reporting information to the network device. .

A possible implementation manner, when the type of the above-mentioned signal parameter reporting amount is the absolute value of the difference value of the signal parameter, the above-mentioned reporting threshold condition may be: the absolute value of the difference value of the signal parameter is greater than or equal to the reporting trigger threshold. value.
