Description

Measuring method, first device and second device

The present application claims priority to Chinese Patent Application No. 201101450464.0, filed on May 11, 2018, the entire disclosure of which is incorporated herein by reference. Combined in this application.

Technical field

The present application relates to the field of communications technologies, and in particular, to a measurement method, a first device, and a second device.

Background technique

In the standardization process of the 5th generation wireless communication system (5G) under study by the 3rd generation partnership project (3GPP), it is proposed to use the synchronization signal block for mobility measurement. The synchronization signal occupies approximately 4.5 ms of time domain resources in time. Therefore, in order to support synchronization signal block based mobility measurements, the base station needs to configure measurement resources for synchronizing signal blocks. The minimum time domain duration of this measurement resource is 5-6 ms in order to include all possible synchronization signal blocks transmitted from different base stations. However, in the 5G study, it is also proposed to use the channel state information reference signal CSI-RS (CSI-RS) for mobility measurement. The CSI-RS occupies fewer symbols in the time domain and can be randomly distributed to different time slots.

If continuous measurement is performed using the measurement resources for synchronizing signal blocks in the prior art, the measurement overhead of the system is inevitably increased. Meanwhile, if the UE always receives CSI-RSs from different beam directions transmitted from different base stations in each time slot, the UE will frequently switch the reception beams in the time slots, causing the UE to The reception on the physical downlink shared channel (PDSCH) is frequently interrupted, affecting the service data transmission performance of the UE, affecting the peak rate and user experience that can be achieved.

Summary of the invention

The present application provides a measurement method, a first device, and a second device, which are used to solve the technical problem that the existing downlink CSI measurement solution affects the service data transmission performance of the terminal device.

In a first aspect, the embodiment of the present application provides a measurement method, where a first message is sent by a first device to a second device, where the first message indicates that the first device is a CSI-RS measurement resource configured by the second device, and each CSI The RS measurement resources include symbols for transmitting CSI-RS, X symbols before symbols for transmitting CSI-RS, and Y symbols after symbols for transmitting CSI-RS, and X and Y are positive integers; After receiving the first message, the second device performs measurement on the at least one CSI-RS measurement resource according to the first message, and obtains the measurement result, and reports the measurement result to the first device, where at least one CSI-RS measurement resource is used. And may be part or all of the CSI-RS measurement resources in the CSI-RS measurement resources configured by the first device for the second device. The second device performs channel measurement according to the scheme, and has less impact on the service data transmission of the second device.

With the above method, the number of symbols occupied by each CSI-RS measurement resource for measurement can be controlled within N, N is equal to the number of symbols used for transmitting CSI-RS, the sum of X and Y, and the second device is Measurements are made on these symbols, which can avoid the terminal device 102 continuously occupying too many symbols for measurement during the measurement process, and prevent long-term interruption of service data transmission.

Exemplarily, the first message may further indicate, by the first device, at least one CSI-RS transmission resource configured by the second device, where part or all of the at least one CSI-RS transmission resource, and at least one indicated by the first message The CSI-RS measurement resource has a corresponding relationship; or the at least one CSI-RS measurement resource indicated by the first message has a correspondence with some or all of the at least one CSI-RS transmission resource configured by the first device for the second device. . The above method is used, and the specific information of the CSI-RS transmission resource does not need to be carried in the first message, and the at least one CSI-RS transmission resource corresponding to the CSI-RS transmission resource may be used, for example, by using a bitmap or a CSI-RS transmission resource. The number information) indicates the CSI-RS measurement resources, thereby saving signaling overhead.

For example, the first message may include a DCI, which is used to indicate the CSI-RS measurement resource in the target time slot, where the target time slot may be a time slot in which the DCI is located, or may be a time slot scheduled by the DCI. In an implementation, the DCI may include a first field of M bits to indicate CSI-RS measurement resources. With this method, the CSI-RS measurement resource can be indicated by DCI, which further saves signaling overhead.

For example, the symbol for transmitting the CSI-RS in the CSI-RS measurement resource may also be a plurality of symbols that are consecutive in the time domain, where the first device may indicate the information to the second device by using the CSI-RS repetition indication information. The symbols used to transmit the CSI-RS are a plurality of symbols that are consecutive in time domain; the CSI-RS repetition indication information may also be used to indicate the number of consecutive symbols for transmitting CSI-RS in the time domain, so that the UE 102 determines the CSI- RS measurement resources.

Exemplarily, the CSI-RS measurement resource used in the second device measurement should satisfy at least one of the following conditions to further reduce the impact of channel measurement on service data transmission:

The control resource set of the physical downlink control channel PDCCH is not included in the symbol of the CSI-RS measurement resource;

There is no uplink transmission on the symbol of the CSI-RS measurement resource;

There is no scheduled physical downlink shared channel PDSCH on the symbol of the CSI-RS measurement resource;

Exemplarily, each CSI-RS measurement resource in the CSI-RS measurement resource configured by the first device for the second device may be located in the same time slot, so that the second device does not exceed one continuous market per measurement. The duration of the time slot further reduces the impact of measurements on traffic data transmission.

Exemplarily, the X symbols before the symbol for transmitting the CSI-RS may not be used for the first device to send the message or the signal, and the Y symbols after the symbol for transmitting the CSI-RS may not be used for the first device. Send a message or signal. Correspondingly, the second device may not receive the service data on the data resource with the same time domain location as the CSI-RS measurement resource when performing measurement according to the CSI-RS measurement resource.

For example, the symbol occupied by the CSI-RS measurement resource may be determined according to the subcarrier spacing of the CSI-RS in the CSI-RS measurement resource, where the duration of the symbol occupied by the CSI-RS measurement resource is the foregoing The integer multiple of the symbol duration of the PDSCH of the second device.

Exemplarily, the second device may determine the quantity of the at least one CSI-RS measurement resource according to its own receiving capability. In an implementation, if the second device supports only a single independent transceiver channel, the second device determines the quantity of the at least one CSI-RS measurement resource, and the second device determines the at least one CSI - the number of RS measurement resources is not greater than Z ₁ , or determining that the number of the at least one CSI-RS measurement resource is less than Z ₁ ; or, if the second device supports multiple independent transceiver channels, the second device determines The number of the at least one CSI-RS measurement resource is not greater than Z ₂ , or the number of the at least one CSI-RS measurement resource is determined to be less than Z ₂ , where Z _{2 is} greater than Z ₁ , Z ₁ , Z ₂ Is a positive integer. By adopting the above method, the second device can be prevented from performing excessive channel measurement when the receiving capability is insufficient, thereby affecting service data transmission.

In a second aspect, another measurement method provided by the embodiment of the present application may be implemented by the following steps:

The second device determines at least one channel state information reference signal CSI-RS measurement resource, wherein each of the CSI-RS measurement resources includes a symbol for transmitting a CSI-RS, and the symbol for transmitting the CSI-RS X symbols and Y symbols after the symbol for transmitting the CSI-RS, X, Y are positive integers;

The second device performs measurement on the at least one CSI-RS measurement resource to obtain a measurement result;

The second device sends the measurement result to the first device.

With the above method, the number of symbols occupied by the second device for measuring CSI-RS measurement resources can be controlled within N, N is equal to the number of symbols used for transmitting CSI-RS, the sum of X and Y, and the second device. Measurements on these symbols can avoid the terminal device 102 continuously taking too many symbols for measurement during the measurement process, preventing long-term interruption of service data transmission.

Exemplarily, the at least one CSI-RS measurement resource has a corresponding relationship with some or all of the at least one CSI-RS transmission resource acquired by the second device.

Exemplarily, the at least one CSI-RS transmission resource may be part or all of the CSI-RS measurement resources of the CSI-RS measurement resources configured by the first device for the second device. Therefore, the first device may indicate the CSI-RS measurement resource to the second device by using at least one CSI-RS transmission resource corresponding to the CSI-RS transmission resource, thereby saving signaling overhead.

Exemplarily, the method may further include:

The second device receives downlink control information DCI, where the DCI is used to indicate a CSI-RS measurement resource in a target time slot, where the target time slot is a time slot in which the DCI is located, or the target time slot is The time slot scheduled by the DCI. Exemplarily, the DCI includes a first field that is longer than M bits, and the first field is used to indicate the CSI-RS measurement resource from the target time slot. With this method, the CSI-RS measurement resource can be indicated to the second device by using the DCI, thereby further saving signaling overhead.

Exemplarily, the at least one CSI-RS measurement resource satisfies at least one of the following conditions to further reduce the impact on the service data transmission when measuring the CSI-RS measurement resource:

Exemplarily, the symbol for transmitting the CSI-RS in the CSI-RS measurement resource is a plurality of symbols that are consecutive in the time domain. For example, the second device may further receive CSI-RS repetition indication information sent by the first device, where CSI-RS repetition indication information is used to transmit symbols of the CSI-RS as multiple symbols in a time domain continuation; CSI The -RS repeat indication information may also be used to indicate the number of consecutive symbols for transmitting CSI-RS in the time domain, in order for the UE 102 to determine CSI-RS measurement resources.

Exemplarily, the X symbols before the symbol for transmitting the CSI-RS may not be used for the first device to send the message or the signal, and the Y symbols after the symbol for transmitting the CSI-RS may not be used for the first device.

It is possible to implement or carry out the various illustrative logical blocks, modules and circuits described in connection with the present disclosure. The processor may also be a combination of computing functions, for example, including one or more microprocessor combinations, combinations of digital signal processors and microprocessors, and the like.

The cellular mobile communication system 100 is taken as an example to describe a specific step of the measurement method provided by the embodiment of the present application. The network device 101 is a first device, and the terminal device 102 is a second device. As shown in FIG. The method includes the following steps:

Step S101: The network device 101 sends a first message to the terminal device 102, where the first message is used to indicate the R CSI-RS measurement resources configured by the network device 101 for the terminal device 102, where each CSI-RS measurement resource is included for The symbols of the CSI-RS, the X symbols before the symbols used to transmit the CSI-RS, and the Y symbols after the symbols used to transmit the CSI-RS, R, X, and Y are positive integers; in implementation, the first The CSI-RS measurement resource indicated by the message may be at least one CSI-RS measurement resource configured by the network device 101 for the terminal device 102;

Step S102: The terminal device 102 receives the first message sent by the network device 101.

Step S103: The terminal device 102 performs measurement on at least one CSI-RS measurement resource to obtain a measurement result.

Step S104: the terminal device 102 sends the measurement result to the network device 101.

Step S105: The network device 101 receives the measurement result sent by the terminal device 102.

With the above method, the terminal device 102 can perform measurement on at least one CSI-RS measurement resource in the CSI-RS measurement resource configured by the network device 101, because the number of symbols occupied by each CSI-RS measurement resource can be controlled within N, N is equal to the sum of the number of symbols used for transmitting the CSI-RS, X and Y, thereby preventing the terminal device 102 from continuously occupying too many symbols for measurement, preventing long-term interruption of service data transmission.

Exemplarily, the symbols occupied by each CSI-RS measurement resource indicated by the first message may be limited to a limited number of symbols N, where the N is equal to the number of symbols used for transmitting the CSI-RS. The sum of X, Y and Y, the network device 101 can also control the values of X and Y, for example, let X=Y=1, or let X=Y=2, further shortening the service for the terminal device 102. The time during which the data transmission was interrupted by the measurement.

Exemplarily, each CSI-RS measurement resource configured by the network device 101 for the terminal device 102 may be located in the same slot, so that the duration of the measurement by the terminal device 102 does not exceed one time slot, further reducing the service data transmission. Interrupt duration.

Illustratively, at least one CSI-RS measurement resource can be used for mobility measurements, or for wireless link monitoring, or for beam management.

Exemplarily, if at least one CSI-RS measurement resource is applied to the beam management of the terminal device 102, the network device 101 may be the serving base station of the terminal device 102, and the network device 101 indicates to the terminal device 102 by using the first message. The at least one CSI-RS measurement resource, the terminal device 102 may perform measurement on all the CSI-RS measurement resources indicated by the first message; or in the measurement method provided by the embodiment of the present application, the terminal device 102 may also receive the first message. Measurements are made on a portion of the CSI-RS measurement resources in all of the indicated CSI-RS measurement resources.

For example, as shown in FIG. 7, if both X and Y are 1, and the number of symbols used to transmit the CSI-RS is also 1, the CSI-RS measurement resource 700 configured by the network device 101 for the terminal device 102 may include for transmission. The symbol 701 of the CSI-RS, one symbol 702 before the symbol 701 for transmitting the CSI-RS, and one symbol 703 after the symbol 701 for transmitting the CSI-RS.

Exemplarily, the symbol for transmitting CSI-RS included in the CSI-RS measurement resource configured by the network device 101 may also be multiple time-domain continuous symbols, for example, two consecutive symbols, and then the CSI-RS measurement is performed at this time. The resource includes two consecutive symbols for transmitting CSI-RS, X symbols before symbols for transmitting CSI-RS, and Y symbols after symbols for transmitting CSI-RS, and X and Y are positive integers. For example, the network device 101 may send CSI-RS repetition indication information to the terminal device 102 to indicate that the symbol used for transmitting the CSI-RS is a plurality of symbols in a time domain continuation, and the CSI-RS repetition indication information may further indicate the transmission CSI- The number of consecutive symbols of the RS.

Exemplarily, in the implementation of step S101, the first message indicates the CSI-RS measurement resource configured by the network device 101 for the terminal device 102 in any of the following manners:

In a first manner, the first message directly indicates the CSI-RS measurement resource configured by the network device 101 for the terminal device 102, for example, a symbol indicating the CSI-RS measurement resource. With this solution, the network device 101 directly informs the terminal device 102 of the symbols of the R CSI-RS measurement resources configured for the terminal device 102. After receiving the first message, the terminal device 102 can use all the CSIs indicated by the first message. The measurement is performed on the symbol of at least one CSI-RS measurement resource in the RS measurement resource.

For example, as shown in FIG. 8, the network device 101 indicates to the terminal device 102 through the first message that there are 3 CSI-RS measurement resources in the time slot S, wherein the CSI-RS measurement resource A is located at the symbol position 801, CSI- The RS measurement resource B is located at the symbol position 802, and the CSI-RS measurement resource C is located at the symbol position 803. The terminal device 102 can select at least one symbol from the symbol position 801, the symbol position 802, and the symbol position 803 after receiving the first message. The position is measured.

In the second mode, the first message further indicates that the network device 101 is configured to the at least one CSI-RS transmission resource of the terminal device 102, where part or all of the at least one CSI-RS transmission resource indicated by the first message is a terminal with the network device 101. At least one CSI-RS measurement resource configured by the device 102 has a corresponding relationship. In an implementation, the first message may indicate at least one symbol for transmitting the CSI-RS. It should be noted that at least one CSI-RS transmission resource has a corresponding relationship with at least one CSI-RS measurement resource, that is, a CSI-RS transmission resource can be determined according to each CSI-RS measurement resource. For example, the CSI-RS transmission resource configured by the network device 101 indicated by the first message for the terminal device 102 is the symbol 701 for transmitting the CSI-RS as shown in FIG. 7, and the CSI-RS measurement corresponding thereto is used. The resource may be a CSI-RS measurement resource 700 including the symbol 701 for transmitting a CSI-RS. In addition, the first message may also indicate the number of the at least one CSI-RS transmission resource that the network device 101 configures for the terminal device 102.

In an embodiment, the first message may carry a bit bitmap, which is used to indicate which CSI-RS measurement resources corresponding to the CSI-RS transmission resources are used by the network device 101 for the CSI-RS transmission resource configured by the terminal device 102. 101 is a CSI-RS measurement resource configured for the terminal device 102. For example, the network device 101 indicates to the terminal device 102 that the 16 CSI-RS transmission resources configured for the terminal device 102 by using the first message, and further, the network device 101 also carries a 16-bit bitmap with the first message. Each bit in the bit bitmap corresponds to a CSI-RS transmission resource, wherein the bit value in the bit bitmap can be set to a specific value, such as set to 1, to indicate the CSI-RS corresponding to the bit. The CSI-RS measurement resource corresponding to the transmission resource is a CSI-RS measurement resource configured by the network device 101 for the terminal device 102. After receiving the first message, the terminal device 102 may take the value of the corresponding bitmap. The CSI-RS measurement resource corresponding to the CSI-RS transmission resource of 1 is used as the CSI-RS measurement resource configured by the network device 101 for the terminal device 102, so that the CSI-RS measurement resource can be measured.

In another implementation manner, the first message may carry the number of the CSI-RS transmission resource corresponding to the CSI-RS measurement resource, to indicate that the CSI-RS measurement resource corresponding to the CSI-RS transmission resource is the network device 101 as the terminal device 102. Configured CSI-RS transmission resources. For example, the network device 101 indicates to the terminal device 102, by using the first message, 16 CSI-RS transmission resources configured for the terminal device 102, where the numbers of the CSI-RS transmission resources are 0 to 15, respectively, and the network device 101 is The first message carries information indicating that the CSI-RS transmission resources are numbered 1, 2, and 4. After receiving the first message, the terminal device 102 may transmit the CSI-RS transmission resources numbered 1, 2, and 4. The corresponding CSI-RS measurement resource is used as the CSI-RS measurement resource configured by the network device 101 for the terminal device 102, and is measured by the network device 101 for the CSI-RS measurement resource configured by the terminal device 102.

In another embodiment, the network device 101 may further classify CSI-RS transmission resources, so that the network device 101 may indicate a certain type of transmission resource in the first message to indicate CSI-RS measurement corresponding to the transmission resource of the type. Resources are CSI-RS measurement resources. For example, the K CSI-RS transmission resources configured by the network device 101 for the terminal device 102 may be divided into L groups. The specific manner may be that the modulo operation is performed on the number L of all CSI-RS transmission resources, and the modulo operation result is obtained. The same CSI-RS transmission resource is used as a group, and the group identifier of each group of CSI-RS transmission resources may be the operation result of the modulo operation. Thereafter, the network device 101 may indicate a group of CSI-RS transmission resources by using the first message. The terminal device 102 is provided such that the terminal device 102 can perform measurements on the CSI-RS measurement resources corresponding to the set of CSI-RS transmission resources.

For example, if the network device 101 configures 16 CSI-RS transmission resources for the terminal device 102, the CSI-RS transmission resources are numbered from 0 to 15, respectively. If the CSI-RS transmission resources are divided into eight groups, the CSI- The packet case of the RS transmission resource is as shown in Table 1. The network device 101 can indicate at least one set of CSI-RS transmission resources to the terminal device 102 through the group identity.

CSI-RS传输资源编号CSI-RS transmission resource number	00	11	22	33	44	55	66	77	88	99	1010	1111	1212	1313	1414	1515
CSI-RS传输资源的组标识Group ID of CSI-RS transmission resources	00	11	22	33	44	55	66	77	00	11	22	33	44	55	66	77

Table 1 CSI-RS transmission resource grouping table

Exemplarily, according to the time slot number, the first message is used to indicate that the terminal device 102 performs measurement according to different groups of CSI-RS transmission resources on different time slots. Specifically, the network device 101 may perform a modulo operation on the K CSI-RS transmission resources configured by the terminal device 102, and use the CSI-RS transmission resources with the same modulo operation result as a group, and each group of CSI-RSs The group identifier of the transmission resource may be the operation result of the modulo operation, and at the same time, the slot number may be modulo-calculated to divide the time slot into L groups, and the group identifier of each group of slots may be modulo operation. As a result of the operation, in the implementation, the CSI-RS transmission resource in the slot of the group ID L0 may be indicated by the first message, and the CSI-RS transmission resource with the group identifier L0.

With this method, all CSI-RS transmission resources can be allocated to different time slots for measurement, and the terminal device 102 is prevented from being measured in the same time slot and on all CSI-RS transmission resources indicated by the network device 101. The data transmission in the time slot, at the same time, the method can also ensure that the terminal device 102 measures all the CSI-RS transmission resources indicated by the network device 101, thereby improving the measurement effect.

For example, if the network device 101 configures 16 CSI-RS transmission resources for the terminal device 102, the CSI-RS transmission resources are numbered from 0 to 15, respectively. If the CSI-RS transmission resources are divided into eight groups, the CSI- The packet status of the RS transmission resource is as shown in Table 1. In addition, the network device 101 can also perform the modulo operation on the slot number pair 8, thereby dividing the time slot into eight groups, and the grouping situation is as shown in Table 2. The network device 101 can By using the first message, the CSI-RS measurement resource on the time slot with the group identifier 0, such as 0, 8, or 16 is numbered as the CSI-RS whose group identifier is 0, such as 0, 8, or 16, by the terminal device 102. The CSI-RS measurement resource corresponding to the transmission resource.

Table 2 Time slot grouping table

In addition, in the implementation, the slot number in the above solution may be replaced by the number of the transmission period, where the transmission period may be composed of multiple consecutive time slots, for example, the transmission period may be ten consecutive time slots. Therefore, all the CSI-RS transmission resources configured by the network device 101 for the terminal device 102 can be allocated to different transmission periods for measurement, thereby further reducing the channel measurement performed by the terminal device 102 in the time slot for the service data transmission in the time slot. Interruption time.

In the third mode, the at least one CSI-RS measurement resource indicated by the first message has a corresponding relationship with some or all of the CSI-RS transmission resources of the at least one CSI-RS transmission resource determined by the terminal device 102. The at least one CSI-RS transmission resource determined by the terminal device 102 may be a CSI-RS transmission resource configured by the network device 101 for the terminal device 102, and the terminal device 102 may perform radio resource control according to the radio resource control sent by the network device 101. The RRC) message determines the CSI-RS transmission resource. In addition, the terminal device 102 may also determine the CSI-RS transmission resource according to the system message sent by the network device 101.

In an embodiment, the first message may carry a bit bitmap to indicate which CSI-RS measurement resources corresponding to the CSI-RS transmission resources determined by the terminal device 102 are the network device 101 as the terminal. The CSI-RS measurement resource configured by the device 102. Wherein, each bit in the bit bitmap corresponds to one CSI-RS transmission resource, wherein the value of the bit in the bit bitmap can be set to a specific value, such as set to 1, to indicate the CSI corresponding to the bit. The CSI-RS measurement resource corresponding to the RS transmission resource is a CSI-RS measurement resource configured by the network device 101 for the terminal device 102, and after receiving the first message, the terminal device 102 can take the corresponding bitmap. The CSI-RS measurement resource corresponding to the CSI-RS transmission resource with a value of 1 is used as the CSI-RS measurement resource configured by the network device 101 for the terminal device 102 so that the CSI-RS measurement resource can be measured.

In another implementation manner, the first message may carry the number of the CSI-RS transmission resource corresponding to the CSI-RS measurement resource, to indicate that the CSI-RS measurement resource corresponding to the CSI-RS transmission resource is the network device 101 as the terminal device. 102 configured CSI-RS transmission resources. For example, the network device 101 indicates to the terminal device 102 that it is 16 CSI-RS transmission resources configured for the terminal device 102 by using an RRC message, where the numbers of the CSI-RS transmission resources are 0 to 15, respectively, and the network device 101 is in the After the message carries the information indicating that the CSI-RS transmission resources are 1, 2, and 4, the terminal device 102 may correspond to the CSI-RS transmission resources numbered 1, 2, and 4 after receiving the first message. The CSI-RS measurement resource is used as the CSI-RS measurement resource configured by the network device 101 for the terminal device 102.

In another implementation manner, if the terminal device 102 can determine at least one CSI-RS transmission resource configured by the network device 101 for the terminal device 102 according to the RRC message sent by the network device 101, the network device 101 can also transmit the CSI-RS. The resources are classified, so that the network device 101 can indicate a certain type of transmission resource in the first message to indicate that the transmission resource has a corresponding relationship with the CSI-RS measurement resource. To save the space of the application file, the network device 101 indicates the implementation manner of the at least one set of CSI-RS transmission resources to the terminal device 102 by using the first message, and may refer to the implementation manner exemplified in the second method.

In another implementation manner, the network device 101 may further indicate, according to the time slot number, that the terminal device 102 performs measurement according to different groups of CSI-RS transmission resources on different time slots, and the implementation manner thereof may refer to mode two. An embodiment in which the terminal device 102 performs measurement according to different sets of CSI-RS transmission resources on different time slots according to the slot number; or the network device 101 may further use the network device 101 as the terminal device according to the number of the transmission period. All the CSI-RS transmission resources configured by the 102 are allocated to different transmission periods for measurement. For the implementation manner, all the CSI-RSs configured by the network device 101 for the terminal device 102 according to the number of the transmission period may be referred to in the second embodiment. An embodiment in which resources are allocated to measurements on different transmission cycles.

In the implementation of step S101, the first message may be downlink control information (DCI) sent by the network device 101 to the terminal device 102, or may be an RRC message or the like.

The possible implementation of step S101 provided by the embodiment of the present application is as follows:

The network device 101 sends a DCI to the terminal device 102, which can be used to indicate the CSI-RS measurement resource configured by the network device 101 in the target time slot for the terminal device 102. For example, the terminal device 102 can transmit part or all of the target time slot. The CSI-RS measurement resource corresponding to the resource is used as the at least one CSI-RS measurement resource configured by the network device 101 for the terminal device 102, where the target time slot may be a time slot in which the DCI is located, or a time slot scheduled by the DCI, for example, The DCI is used to schedule the next time slot for transmitting the DCI, and the next time slot for transmitting the DCI can be used as the target time slot. In an implementation, the part or all of the transmission resources in the target time slot may be at least one CSI-RS transmission resource indicated by the network device 101 to the terminal device 102 by using the first message; The total transmission resource may also be at least one CSI-RS transmission resource determined by the terminal device 102 in the foregoing mode 3.

Exemplarily, the DCI may also carry a first field that is longer than M bits to indicate CSI-RS measurement resources in the target time slot, where the first field may be a bit bitmap. Specifically, in the target time slot, the number of transmission resources configured by the network device 101 for the terminal device 102 is three, and the network device 101 can also carry a 3-bit bitmap in the DCI, each of the bit bitmaps. The bit corresponds to a CSI-RS transmission resource, and the network device 101 can set the value of some or all of the bits to a specific value, such as 1 to indicate the CSI corresponding to the CSI-RS transmission resource corresponding to the bit. The RS measurement resource is a CSI-RS measurement resource configured by the network device 101 for the terminal device 102, and after receiving the DCI, the terminal device 102, in the time slot in which the DCI is located, has a corresponding bit value of 1 transmission resource. The corresponding CSI-RS measurement resource is used as the CSI-RS measurement resource configured by the network device 101 for the terminal device 102; or, after receiving the DCI, the terminal device 102 will allocate the corresponding bit in the time slot scheduled by the DCI. The CSI-RS measurement resource corresponding to the transmission resource with a value of 1 is used as the CSI-RS measurement resource configured by the network device 101 for the terminal device 102.

Exemplarily, the DCI may also carry information indicating the number of the CSI-RS transmission resource. Specifically, if the number of CSI-RS transmission resources configured by the network device 101 for the terminal device 102 is 3, the network device 101 may further carry the information of the number of the CSI-RS transmission resource in the DCI, such as carrying the CSI. - The information of the number 1 of the RS transmission resource, the terminal device 102, after receiving the DCI, the CSI-RS measurement resource corresponding to the transmission resource numbered 1 in the time slot in which the DCI is located, as the network device 101 as the terminal device The configured CSI-RS measurement resource is further measured on the CSI-RS measurement resource; or, after receiving the DCI, the terminal device 102 corresponds to the transmission resource numbered 1 in the time slot scheduled by the DCI. The CSI-RS measurement resource is used as a CSI-RS measurement resource configured by the network device 101 for the terminal device 102, and is further measured on the CSI-RS measurement resource.

Exemplarily, the terminal device 102 can determine the quantity of at least one CSI-RS measurement resource to perform measurement according to its own receiving capability. For example, the terminal device 102 can determine the maximum number of times the terminal device 102 measures on at least one CSI-RS measurement resource according to the number of independent transceiver channels that can be supported by itself: if the terminal device 102 determines that it only supports receiving through a single independent transceiver channel. The number of CSI-RS measurement resources determined by the terminal device 102 is not greater than Z ₁ ; or the number of CSI-RS measurement resources determined by the terminal device 102 is less than Z ₁ ; if the terminal device 102 determines that it supports multiple independent transceiver channels If the receiving is performed, the number of CSI-RS measurement resources determined by the terminal device 102 is not greater than Z ₂ ; or the number of CSI-RS measurement resources determined by the terminal device 102 is less than Z ₂ , and Z ₁ and Z ₂ are positive integers. In an embodiment, Z _{2 may be} configured by network device 101 to be a positive integer greater than Z ₁ , such that a terminal device supporting reception through multiple transceiver channels may perform more measurements within the time slot to obtain For better measurement results, only terminal devices that receive through a single independent transceiver channel perform fewer measurements in the time slot to reduce the impact on terminal device service data reception. In addition, in the implementation, the foregoing Z ₁ may also be used to indicate that only the maximum number of CSI-RS measurement resources that can be determined in one time slot by the receiving terminal device through a single independent transceiver channel is supported, and the above Z ₂ may also be used to indicate The maximum number of CSI-RS measurement resources that can be determined in one time slot by receiving terminal devices through multiple independent transceiver channels.

In the implementation of step S103, the terminal device 102 may perform measurement on a CSI-RS measurement resource that satisfies at least one of the preset conditions, and the preset condition may include at least one of the following conditions:

The symbol of the CSI-RS measurement resource does not include the control resource set of the PDCCH, the uplink of the CSI-RS measurement resource, and the symbol of the CSI-RS measurement resource without the scheduled PDSCH or the CSI-RS measurement resource. The scheduled PDSCH is not used to carry high reliability and/or low latency services. Therefore, the terminal device 102 performs measurement on the CSI-RS measurement resource that satisfies the preset condition, and can further reduce the influence of the reception interruption of the transmission in the measurement process on the transmission of the service data.

In an implementation manner, before the step S103, the terminal device 102 may further determine whether the CSI-RS measurement resource meets the preset condition after determining, by the network device 101, the CSI-RS measurement resource indicated by the first message, if the condition is met. Then, the terminal device 102 can perform measurement on the CSI-RS measurement resource; otherwise, the terminal device 102 does not perform measurement on the CSI-RS measurement resource.

For example, after receiving the first message, the terminal device 102 determines that the CSI-RS measurement resource configured by the network device 101 includes the CSI-RS measurement resource A as shown in FIG. 8, and the CSI-RS measurement resource A is located. The symbol location 801 includes a control resource set that does not include a PDCCH on a symbol of a CSI-RS measurement resource, no uplink transmission on a symbol of a CSI-RS measurement resource, and a downlink PDSCH that is not scheduled on a symbol of a CSI-RS measurement resource, and the terminal The device 102 may determine not to perform measurement on the CSI-RS measurement resource A after determining the control resource set of the PDCCH on the CSI-RS measurement resource A; or, the terminal device 102 may have a line transmission on the determined CSI-RS measurement resource A. After the data, it is determined that the measurement is not performed on the CSI-RS measurement resource A; or, the terminal device 102 may determine that there is a scheduled downlink PDSCH on the CSI-RS measurement resource A, and determine not to perform measurement on the CSI-RS measurement resource A.

Exemplarily, the symbol occupied by the CSI-RS measurement resource may be determined according to the subcarrier spacing of the CSI-RS in the CSI-RS measurement resource, and the symbol occupied by the CSI-RS measurement resource is the CSI-RS measurement by the terminal device 102. When the measurement is performed on the resource, the terminal device 102 cannot perform the symbol on the data transmission resource of the service data transmission, wherein the duration of the symbol occupied by the CSI-RS measurement resource is an integer multiple of the symbol duration of the PDSCH of the terminal device 102.

As shown in FIG. 9a, if the subcarrier spacing of the CSI-RS is the same as the subcarrier spacing of the PDSCH of the terminal device 102, the symbol occupied by the CSI-RS measurement resource 901 is the symbol 902 on the PDSCH, that is, the terminal device 102. When performing measurements on the CSI-RS measurement resource 901, the terminal device 102 cannot simultaneously perform service data transmission on the symbol 902 of the PDSCH, wherein the symbol 902 of the PDSCH is the same as the time domain position of the CSI-RS measurement resource 901.

If the subcarrier spacing of the CSI-RS is twice the subcarrier spacing of the PDSCH of the terminal device 102, for example, the subcarrier spacing of the CSI-RS is 120 kilohertz (kHz), and the subcarrier spacing of the PDSCH is 60 kHz, at this time, the CSI The symbol length of the -RS is half the symbol length of the PDSCH. As shown in FIG. 9b, the first CSI-RS measurement resource determined by the terminal device 102 includes only one symbol for transmitting CSI-RS, that is, the symbol 903, and the number of CSI-RS symbols included in the first CSI-RS measurement resource is 3. If the time domain start position of the symbol 903 is the same as the time domain start position of the symbol 904 of the PDSCH, at this time, the terminal device 102 has a CSI-RS symbol before the symbol 903, the symbol 903, and a CSI- after the symbol 903. When the measurement is performed on the RS symbol, the data cannot be received on the symbol 904 and the symbol 905 on the PDSCH.

For example, the second CSI-RS measurement resource determined by the terminal device 102 includes only one symbol 906 for transmitting a CSI-RS, and the second CSI-RS measurement resource includes a CSI-RS symbol number of three, if the symbol 906 is before The time domain start position of one CSI-RS symbol is the same as the time domain start position of the symbol 904 of the PDSCH, at this time, the terminal device 102 is at a symbol 906, a CSI-RS symbol preceding the symbol 906, and a symbol 906. When the measurement is performed on the CSI-RS symbol, the data cannot be received on the symbol 904 and the symbol 907 on the PDSCH.

If the subcarrier spacing of the CSI-RS is 4 times the subcarrier spacing of the PDSCH of the terminal device 102, for example, the subcarrier spacing of the CSI-RS is 60 kilohertz (kHz), and the subcarrier spacing of the PDSCH is 15 kHz, according to the CSI. The length of the slot determined by the subcarrier spacing of the RS is one quarter of the length of the slot determined according to the subcarrier spacing of the PDSCH.

For example, as shown in FIG. 9c, the first CSI-RS measurement resource determined by the terminal device 102 includes only one symbol 908 for transmitting a CSI-RS, and the number of CSI-RS symbols included in the first CSI-RS measurement resource is 3. If the time domain start position of a CSI-RS symbol preceding the symbol 908 in the first CSI-RS measurement resource is the same as the time domain start position of the PDSCH symbol 909, at this time, the terminal device 102 is at symbol 908, symbol 908. When a previous CSI-RS symbol and a CSI-RS symbol following the symbol 908 are measured, data reception cannot be performed on the symbol 909 on the PDSCH; for example, the second CSI-RS measurement resource determined by the terminal device 102. Only one symbol 910 for transmitting a CSI-RS is included, and the number of CSI-RS symbols included in the second CSI-RS measurement resource is 3, if a CSI-RS symbol after the symbol 908 in the first CSI-RS measurement resource The time domain end position is the same as the time domain end position of the PDSCH symbol 909. At this time, when the terminal device 102 performs measurement on the symbol 910, one CSI-RS symbol before the symbol 910, and one CSI-RS symbol after the symbol 910, Unable to perform data on symbol 909 on PDSCH Receiving; for example, the third CSI-RS measurement resource determined by the terminal device 102 includes only one symbol 911 for transmitting a CSI-RS, and the third CSI-RS measurement resource includes a CSI-RS symbol number of three, if The time domain start position of the symbol 911 in a CSI-RS measurement resource is the same as the time domain start position of the PDSCH symbol 909. At this time, the terminal device 102 has a CSI-RS symbol and a symbol 911 before the symbol 911 and the symbol 911. When the measurement is performed on one subsequent CSI-RS symbol, the data cannot be received on the symbol 909 and the symbol 912 on the PDSCH; for example, only one of the fourth CSI-RS measurement resources determined by the terminal device 102 is included for transmission. The symbol 913 of the CSI-RS, the number of CSI-RS symbols included in the fourth CSI-RS measurement resource is 3, if the time domain end position of the symbol 913 in the first CSI-RS measurement resource, and the time domain end position of the PDSCH symbol 909 In the same way, at this time, when the terminal device 102 performs measurement on the symbol 913, one CSI-RS symbol before the symbol 913 and one CSI-RS symbol after the symbol 913, one PDSCH symbol that cannot be after the PDSCH symbol 909 and the symbol 909 is Number 914 Reception.

In an embodiment of the measurement method provided by the embodiment of the present application, the X symbols before the symbol for transmitting the CSI-RS in the CSI-RS measurement resource are not used by the network device 101 to send a message or a signal, and/or The Y symbols following the transmission of the symbols of the CSI-RS are not used by the network device 101 to transmit messages or signals to prevent the UE 102 from receiving messages or signals transmitted by the network device 101 when these symbols are being measured. Correspondingly, when the terminal device 102 performs measurement on the at least one CSI-RS measurement resource, the data transmitted on the data transmission resource with the same time domain location of the CSI-RS measurement resource may be punctured, wherein the data transmission The resource may be a time domain resource for transmitting service data, and the data transmission resource is not used by the second device to transmit or receive data.

The puncturing operation means that the terminal device 102 does not receive part of the data (for example, data transmitted on the PDSCH) for some reason. In this case, the terminal device 102 performs the decoding of the unreceived data. The "punch" operation, that is, the unreceived data is completely zeroed when input to the decoder to avoid the occurrence of receiver decoding errors. Specifically, in the embodiment of the present application, when the terminal device 102 performs measurement on the CSI-RS measurement resource, the data transmitted on the PDSCH with the same time domain location as the CSI-RS measurement resource may be punctured to avoid performing measurement on the terminal. The device 102 receives interference caused by data transmitted on the PDSCH.

For example, as shown in FIG. 10, if the terminal device 102 needs to perform data transmission on the PDSCH transmission resource 1001, where the PDSCH transmission resource 1001 occupies 10 symbols, and the terminal device 102 needs to perform channel on the CSI-RS measurement resource 1002. The quality measurement, where the CSI-RS measurement resource 1002 occupies 3 symbols of the PDSCH, the terminal device 102 can correspond to the 3 symbols occupied by the CSI-RS measurement resource A when decoding the data transmitted on the PDSCH transmission resource 1001. The decoding preamble of the data is set to zero.

In addition, in the implementation, the terminal device 102 may perform a rate matching operation on data transmitted on a data transmission resource having the same time domain location as the CSI-RS measurement resource, where the data transmission resource may be used to transmit the service data to the terminal device 102. Time domain resources. When transmitting data, the base station of the service data allocates certain time-frequency resources, for example, 10 symbols, and 6 physical resource blocks (PRBs) are used to transmit the data. It is assumed that the terminal device 102 occupies 10 devices. The 3 symbols in the symbol are measured, and the original terminal device 102 needs to receive the data on 10 symbols, but after subtracting the 3 symbols occupied by the terminal device 102, the terminal device 102 can only receive the 7 symbols. data. From the perspective of the base station transmitting the data, when the base station transmits the PDSCH, the symbol that can actually be used to carry the PDSCH (ie, the symbol that can be used by the terminal device 102 to receive the data) is changed from 10 symbols to 7 symbols, also That is, the time-frequency resources are reduced. In one way, the base station can re-adjust the original service data transmission rate so as to be carried to the reduced time-frequency resources. This adjustment process is usually performed on the channel coding of the PDSCH. The module implements the adjustment of the information bits at the time of encoding to the post-encoding information bit mapping, and adjusts the coding rate of the information bits carried in the PDSCH channel, and the physical resources of the PDSCH that are actually available at the time of matching, thereby being originally 10 The data transmitted on the symbol can be transmitted on 7 symbols, and the terminal device 102 does not affect the complete reception of the data even if it can only receive data on 7 symbols. This process is rate matching. The above process adjusts the coding rate of the information bits carried in the PDSCH channel, and the physical resources of the PDSCH that are actually available at the time of matching. Correspondingly, in order to avoid the reception error, the terminal device 102 performs the corresponding rate matching reception according to the above procedure.

For example, as shown in FIG. 10, if the terminal device 102 needs to perform data transmission on the PDSCH transmission resource 1001, where the PDSCH transmission resource 1001 occupies 10 symbols, and the terminal device 102 needs to perform channel on the CSI-RS measurement resource 1002. Quality measurement, in which the CSI-RS measurement resource 1002 occupies 3 symbols of the PDSCH, the terminal device 102 can perform rate matching operation with the base station transmitting the data, so that the base station matches the coding rate according to the rate at 7 (10-3) Data is transmitted on the symbols, and the terminal device 102 receives the data on 7 symbols at the adjusted rate.

In the implementation of step S103, the measurement performed by the terminal device 102 on the at least one CSI-RS measurement resource may be a measurement of channel quality, including but not limited to reference signal received power (RSRP), reference. The measurement signal received quality (RSRQ), the received signal strength indicator (RSSI), and the signal to interference noise ratio (SINR) are measured to obtain corresponding measurement results. In addition, the terminal device 102 can also perform mobility measurement on at least one CSI-RS measurement resource and obtain a mobility measurement result; the terminal device 102 can also perform wireless link monitoring measurement on at least one CSI-RS measurement resource. And get the measurement results of the wireless link monitoring. Thereafter, in step S104, the terminal device 102 may report the plurality of measurement results obtained in step S103 to the network device 101 respectively; or the terminal device 102 may report the multiple measurement results obtained in step S103 to the network through the same message. Device 101.

In the implementation of step S103, when the terminal device 102 performs measurement on at least one CSI-RS measurement resource, the number of measurements on the CSI-RS measurement resource in the same time slot does not exceed K times, and K may be a network device. The signaling to the terminal device 102 by means of signaling may also be pre-configured in the terminal device 102, thereby preventing the terminal device 102 from performing excessive channel measurement in the same time slot, resulting in transmission and reception of service data of the terminal device 102. Interrupted multiple times.

The specific steps of another measurement method provided by the embodiment of the present application are described by using the cellular mobile communication system 100 as an example. The method specifically includes the following steps as shown in FIG. 6:

Step S201: The terminal device 102 determines a channel state information reference signal CSI-RS measurement resource, where each CSI-RS measurement resource includes a symbol for transmitting a CSI-RS, and X symbols before a symbol for transmitting a CSI-RS And Y symbols after the symbol for transmitting the CSI-RS, X, Y are positive integers; the CSI-RS measurement resource may be configured by the network device 101 for the terminal device 101; exemplary, in the CSI-RS measurement resource CSI-RS is used for mobility measurement; or CSI-RS in CSI-RS measurement resource is used for radio link monitoring; or CSI-RS in CSI-RS measurement resource is used for beam management;

Step S202: The terminal device 102 performs measurement on at least one CSI-RS measurement resource to obtain a measurement result.

Step S203: The terminal device 102 transmits the measurement result to the network device 101.

Step S204: The network device 101 receives the measurement result.

With the above method, the terminal device 102 can perform measurement on at least one CSI-RS measurement resource, wherein the number of symbols occupied by each CSI-RS measurement resource is equal to the number of symbols used to transmit the CSI-RS, X and Y. The sum of the measurements made by the terminal device 102 on these symbols does not occupy too many symbols, so that the measurement method can prevent a long interruption of the transmission of the service data during the measurement by the terminal device 102.

Exemplarily, the value of X and Y may be indicated by the network device 101 to the terminal device 102, or the values of X and Y may be pre-configured in the terminal device 102. For example, the terminal device 102 is instructed by the network device 101 in advance, and the values of X and Y are all 1, thereby further shortening the time for data transmission interruption caused by the measurement of the service by the terminal device 102.

Exemplarily, each CSI-RS measurement resource determined by the terminal device 102 may be located in the same time slot, so that the duration of the measurement by the terminal device 102 does not exceed the duration of one time slot, further reducing the interruption of the service data transmission. duration.

Exemplarily, the CSI-RS measurement resource determined by the terminal device 102 may have a structure as shown in FIG. 7, where the CSI-RS measurement resource 700 determined by the terminal device 102 may include a symbol 701 for transmitting a CSI-RS, A symbol 702 preceding the symbol 701 of the CSI-RS is transmitted, and a symbol 703 following the symbol 701 for transmitting the CSI-RS. In addition, if the symbol for transmitting the CSI-RS in the CSI-RS measurement resource determined by the terminal device 102 may also be multiple time-domain consecutive symbols, for example, two consecutive symbols, the network device 101 may send the terminal device 102. The CSI-RS repeats the indication information to indicate that the symbols used for transmitting the CSI-RS are a plurality of symbols in the time domain contiguous; the CSI-RS repetition indication information may also indicate the number of the plurality of consecutive symbols transmitting the CSI-RS.

In the implementation of step S201, the at least one CSI-RS measurement resource determined by the terminal device 102 may have a corresponding relationship with some or all of the at least one CSI-RS transmission resource acquired by the terminal device 102, where the terminal device 102 The determined at least one CSI-RS transmission resource may be at least one CSI-RS transmission resource indicated by the network device 101 to the terminal device 102 by using an RRC message or a system message, where the at least one transmission resource is the network device 101 being the terminal device 102. Configured resources for transmitting CSI-RS. It should be noted that at least one CSI-RS transmission resource has a corresponding relationship with at least one CSI-RS measurement resource, that is, a CSI-RS measurement resource can be determined according to each transmission resource, for example, The CSI-RS measurement resource corresponding to the CSI-RS measurement resource that the network device 101 indicated by the first message is configured for the terminal device 102 is the symbol 701 for transmitting the CSI-RS as shown in FIG. The CSI-RS measurement resource 700 of the symbol 701 of the RS. In addition, the first message may also indicate the number of the at least one CSI-RS transmission resource that the network device 101 configures for the terminal device 102.

In an implementation manner of the step S201, the terminal device 102 may determine at least one CSI-RS measurement resource according to the DCI sent by the network device 101 to the terminal device 102, where the DCI sent by the network device 101 is used to indicate the target time slot. The CSI-RS measurement resource may be a time slot in which the DCI is located, or may be a time slot scheduled by the DCI.

Exemplarily, the DCI includes a first field that is longer than M bits, and the first field is used to indicate a CSI-RS measurement resource from the target time slot, where the first field may be a bit bitmap, and the first field may also be Information indicating the number of the CSI-RS transmission resource.

For example, the manner in which the first field in the DCI is set, and the manner in which the network device 101 indicates the CSI-RS measurement resource by using the DCI, may refer to the implementation in step S101 of the present application, and the network device 101 indicates the CSI-RS transmission resource through the DCI. Possible implementation.

In the implementation of step S201, the terminal device 102 may further determine the quantity of at least one CSI-RS measurement resource to perform measurement according to its own receiving capability. For example, the terminal device 102 can determine the maximum number of times the terminal device 102 measures on at least one CSI-RS measurement resource according to the number of independent transceiver channels that can be supported by itself: if the terminal device 102 determines that it only supports receiving through a single independent transceiver channel. The number of CSI-RS measurement resources determined by the terminal device 102 is not greater than Z ₁ ; or the number of CSI-RS measurement resources determined by the terminal device 102 is less than Z ₁ ; if the terminal device 102 determines that it supports multiple independent transceiver channels If the receiving is performed, the number of CSI-RS measurement resources determined by the terminal device 102 is not greater than Z ₂ ; or the number of CSI-RS measurement resources determined by the terminal device 102 is less than Z ₂ , and Z ₁ and Z ₂ are positive integers. In an embodiment, Z _{2 may be} configured by network device 101 to be a positive integer greater than Z ₁ , such that a terminal device supporting reception through multiple transceiver channels may perform more measurements within the time slot to obtain A better measurement effect, and only supports UEs receiving through a single independent transceiver channel to perform fewer measurements in the time slot to reduce the impact on UE service data reception. In addition, in the implementation, the foregoing Z ₁ may also be used to indicate that only the maximum number of CSI-RS measurement resources that can be determined in one time slot by the receiving terminal device through a single independent transceiver channel is supported, and the above Z ₂ may also be used to indicate The maximum number of CSI-RS measurement resources that can be determined in one time slot by receiving terminal devices through multiple independent transceiver channels.

In the implementation of step S201, the at least one CSI-RS measurement resource determined by the terminal device 102 should satisfy a preset condition, and the preset condition may include at least one of the following conditions:

The symbol of the CSI-RS measurement resource does not include the control resource set of the PDCCH, the uplink of the CSI-RS measurement resource, and the symbol of the CSI-RS measurement resource without the scheduled PDSCH or the CSI-RS measurement resource. There is a scheduled PDSCH, but the scheduled PDSCH is not used to carry high reliability and/or low latency traffic. Therefore, the terminal device 102 performs measurement on the CSI-RS measurement resource that meets the preset condition, and does not perform measurement on the CSI-RS measurement resource that does not satisfy the above preset condition, which can further reduce the reception interruption of the transmission during the measurement process. The impact of the transmission of data. The terminal device 102 determines whether the CSI-RS measurement resource meets the preset condition, and performs the measurement on the preset condition. The terminal device 102 determines the CSI-RS measurement resource according to the preset condition and is satisfied in step S103.

For example, the symbol occupied by the CSI-RS measurement resource may be determined according to the subcarrier spacing of the CSI-RS in the CSI-RS measurement resource, where the duration of the symbol occupied by the CSI-RS measurement resource is the terminal device 102. The integer number of times of the symbol length of the PDSCH, the symbol occupied by the CSI-RS measurement resource, is the time domain for transmitting the service data when the terminal device 102 performs measurement on the CSI-RS measurement resource, and cannot transmit or receive the service data.

Thereafter, in step S104, the terminal device 102 may report the plurality of measurement results obtained in step S103 to the network device 101 respectively; or the terminal device 102 may report the multiple measurement results obtained in step S103 to the network through the same message. Device 101, completes the measurement process.

The device 101 indicates to the terminal device 102 through signaling, or may be pre-configured in the terminal device 102, thereby preventing the terminal device 102 from performing excessive channel measurement in the same time slot, resulting in service data of the terminal device 102.

Embodiment: UE receiver side

The technical problem that is mainly solved in this embodiment is that in 5G, there is no reference signal covering all cell directions that has been transmitted throughout the cell. The synchronization signal SS (Synchronization Signal) is also transmitted in various directions in a beam manner, and the channel state information reference signal CSI-RS (Channel State Information Reference Signal) only indicates a reference signal in a specific beam direction. Therefore, when receiving downlink control information DCI (Downlink Control Information), the UE needs to know the amplitude of the symbol where the DCI information is located in advance, for example, the UE can accurately adjust the automatic gain control AGC (Automatic Gain Control) of the receiver. The gain factor is such that the demodulation of the DCI has the largest signal to noise ratio (SNR).

The method in this embodiment is to determine the power between the RS and the DCI by configuring the RS of the DCI quasi-co-location QCL (Quasi-Colocation) to be received by the UE, and according to the type of the DCI or the phase of the connected network where the UE is located. Deviation. Based on this power deviation and the signal strength of the detected RS, the UE determines the optimal gain control factor for receiving the DCI to achieve the optimal SNR of the UE receiver.

Specifically, it is seen from the receiver of the UE.

Further, optionally, as described above, the RS herein may be an SS for synchronization, a CSI-RS for measurement, or a TRS (Tracking RS) for synchronization at the time. The invention is not limited thereto.

Further, optionally, the above RS has a QCL relationship with the downlink DCI to be used by the receiver of the UE for the adjustment of the automatic gain control. The QCL relationship includes that the two RSs have the same beam direction, or the same receive beam can be used to receive two types of RSs, or one or more of the channel parameters of the two RSs are determined to be the same. The physical meaning is that the DCI and the RS are transmitted from the same or similar spatial direction, or have experienced the same or similar spatial transmission channels, so as not to affect the UEs to treat them equivalently as signals transmitted in the same direction, Will produce too much error or impact.

Further, optionally, the second device receives the downlink control information according to the reference signal and power deviation information between the downlink control information and the reference signal.

Specifically, optionally, the second device determines, according to the received signal strength of the reference signal and a power deviation between the downlink DCI and the RS, a gain control factor for receiving the downlink DCI, where the second device receives according to the gain control factor. The downlink DCI. For example, the UE first receives the RS, and the obtained power range of the signal has a fluctuation range of [-50, -80] dBm and the power of the downlink DCI is 5 dB higher than the RS, so that the UE can know that the fluctuation range of the downlink DCI signal is [ -45, -75] dBm. Therefore, the UE can determine the gain factor of the AGC appropriately for the reception of the DCI, thereby obtaining the quantized value after the Analog-to-Digital Converter (ADC) of the correct downlink DCI, thereby obtaining the optimal DCI. Receive SNR. On the other hand, if the UE does not know the power difference between the downlink DCI and the RS, the UE may set the gain factor of the erroneous AGC, resulting in a decrease in the received SNR. In the above example, if the gain range of the received DCI is still adjusted to be the same as that of the receiving RS [-50, -80] dBm, the signal of the DCI of the signal quantized by the ADC will be 5 dB less than the actual signal. This is something that needs to be avoided and circumvented in wireless communication systems.

Embodiment: The process of the embodiment on the transmitter side of the base station is similar to that on the receiving side of the UE. The difference is that the processing of the receiver on the UE side is not visible to the base station transmitter, and can only be reflected in the processing process inside the base station and the downlink air interface signal. The transmission process of the order. The following describes the following:

Specifically, from the perspective of the transmitter of the base station, the base station needs to first determine the type of downlink control information that is sent to the UE. The downlink control information can be divided into two types. The first type of downlink control information includes any one of the following: downlink control information indicating a system message, downlink control information indicating a random access response, and downlink control information indicating a paging message. The second type of downlink control information includes any one of the following: downlink control information indicating user specific data, and downlink control information common to a group of users.

The reason why the downlink control information is divided into different types is that the UE can only receive the first type of downlink control information and cannot receive the second type of downlink control information before establishing the RRC (Radio Resource Control) link. Another reason is that the direction of the beam of the first type of downlink control information is often broadcast or not directed to users in a specific direction, and its beam is wider; and the direction of the second type of downlink control information is often multicast or unicast. It points to a user in a particular direction, and its beam is narrower. The antenna gain of the narrower beam in the transmit direction is stronger, so the transmit power above it can be different from the DCI with a wider beam direction. For these two reasons, it is necessary to indicate the power difference between the downlink control information and the reference signal from the UE according to the type of different downlink control information or the connection phase in which the UE is located. For example, if the UE is in the RRC establishment, the UE cannot receive the power difference between the downlink control information and the reference signal through the RRC message. Conversely, after the UE establishes the RRC connection, the RRC message can be used to indicate the power difference between the downlink DCI and the RS.

Further, optionally, the downlink control information common to a group of users includes any one of the following: downlink control information indicating resource preemption; downlink control information indicating a slot format; and downlink control information indicating power control indication information. The downlink control information common to these groups of users is sent to a group of UEs. This group of UEs may be in a similar area in the spatial direction or have the same transmission characteristics.

Further, optionally, different types of downlink control information use the corresponding random access radio network standard (RNTI) to scramble the downlink control information. For example, the downlink control information indicating the resource preemption may use the INT-RNTI to perform CRC scrambling of the DCI; the downlink control information indicating the slot format may use the SFI-RNTI to perform DCI CRC scrambling; and indicate the downlink of the power control indication information. The control information may use TPC-PUSCH-RNTI or TPC-PUCCH-RNTI or TPC-SRS-RNTI for CRC scrambling of DCI. In another example, the UE-specific downlink control information may be used to perform DCI CRC scrambling using UE-specific C-RNTI or CS-RNTI(s) or TC-RNTI or SP-CSI-RNTI.

Further, the base station needs to define the power difference between the DCI and the RS in a predefined manner, so that the UE that does not receive the system message SIB1 can also determine the power difference between the downlink DCI and the RS. After the UE receives the SIB1, the power difference between the first type of DCI and the RS may be indicated by SIB1.

Optionally, when the SIB1 further indicates the power difference between the downlink DCI and the RS, the information in the SIB1 is used to overwrite the predefined information. That is, the UE determines the power difference between the downlink DCI and the RS based on the indication information in the SIB1.

Further, optionally, the power difference between the downlink DCI and the RS may be based on the transmit power of the symbol where the physical downlink control signal PDCCH (Physical Downlink Control Channel) where the DCI is located and the transmit power of the symbol where the RS is located. It can also be defined by using the power difference between the transmit power on the subcarrier where the downlink DCI is located and the transmit power on the subcarrier where the RS is located. The invention is not limited thereto. In general, because the bandwidth between the RS and the DCI is different, the power difference on the subcarriers can be used to define fewer bits to use.

Further, optionally, as described above, the power difference between the first type of control information and the RS is because the beam width occupied by the first type of control information is wider than the beam width occupied by the second type of control information. smaller. Fewer bits can be used to indicate the power difference between the first type of DCI and the RS, thereby achieving the purpose of reducing air interface signaling. Further, since the power difference between the first type of DCI and the RS is indicated in the system message, reducing the overhead of the system message is also important for the transmission efficiency of the network, so fewer bits can be used to indicate the first The power difference between DCI and RS.
