Description

Method and device for indicating channel state measurement parameters

This application claims the priority of the Chinese patent application filed with the State Intellectual Property Office of China with application number 201910518486.0 on June 15, 2019, and the priority of the Chinese patent application with the title of "A method and device for indicating channel state measurement parameters" Right, the entire contents of which are incorporated in this application by reference.

Technical field

The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for indicating channel state measurement parameters.

Background technique

The standby time of the terminal is an important part that affects the user experience. As the fifth generation (5 ^th generation, 5G) new air interface (new radio, NR) system needs to support greater bandwidth, higher transmission rate than the long-term evolution (long term evolution, LTE) systems, wider coverage, Therefore, the power consumption of NR terminals is greater than that of LTE terminals.

In order to reduce the power consumption of the terminal and ensure a good user experience, the 3rd generation partnership project (3GPP) has established a project on the topic of terminal power saving in Rel-16 to study how to reduce terminal power consumption. Optimize the plan to achieve the purpose of terminal energy saving. In the power saving topic, there is the following solution: the network device sends a "PDCCH-based power saving signal" to the terminal to instruct the terminal to perform a series of operations to save power consumption. The power saving signal based on the PDCCH may be in front of an activation period "On Duration" of a discontinuous reception (connected discontinuous reception, C-DRX) to indicate whether the terminal should monitor scheduling during On Duration. In addition, the above-mentioned "PDCCH-based power saving signal" can also be used to indicate other functions, such as instructing the terminal to perform channel state information reference signal (CSI-RS) measurement, and the power saving signal can Trigger an aperiodic CSI-RS and a CSI report. Through CSI measurement and reporting, the network device can know the specific status of the downlink channel, so that it can use more appropriate parameters for scheduling in On Duration, thereby improving transmission efficiency and transmission speed. In this way, the terminal can enter a short sleep state after receiving/sending data quickly, thereby saving power consumption.

The aperiodic CSI-RS trigger offset value (triggering offset) determines that the PDCCH and the CSI-RS triggered by it are in the same slot or in different time slots. If the triggering offset of the CSI-RS configured by the network device is too small (for example, 0), in order to avoid data and/or signal loss, after receiving the PDCCH, the terminal must buffer the data and/or signal while decoding the PDCCH, and the terminal needs to be turned on at all times Its own radio frequency module caches data and/or signals, causing waste of power consumption.

One of the simplest solutions is that the network equipment configures the triggering offset of all CSI-RS of the terminal sufficiently large. However, this "configuration restriction" has a great impact on the flexibility of network device configuration. Currently, no suitable solution is provided for the setting of aperiodic CSI-RS trigger offset value.

Summary of the invention

The embodiments of the present application provide a method and device for indicating channel state measurement parameters to reduce terminal power consumption.

In order to achieve the foregoing objectives, the following technical solutions are adopted in the embodiments of this application:

In the first aspect, an embodiment of the application provides a method for indicating channel state measurement parameters. The terminal determines a first channel state information reference signal (CSI-RS) trigger offset value, where the first CSI-RS trigger offset value is based on physical The minimum time slot difference between the time slot where the PDCCH based power saving signal/chanel (PBPSS) of the downlink control channel PDCCH is located and the time slot where the aperiodic CSI-RS triggered by the PBPSS is located; the terminal receives the network equipment The first PBPSS sent; the terminal receives the first CSI-RS sent by the network device; the time slot difference between the time slot where the first PBPSS is located and the time slot where the first CSI-RS triggered by the first PBPSS is located is not less than the first CSI -RS trigger offset value.

Among them, PBPSS is used to indicate whether the terminal needs monitoring and scheduling during OnDuration before the activation period OnDuration of a discontinuous reception.

Among them, CSI-RS is used for the terminal to measure the channel state between the terminal and the network device. In addition to PBPSS can be used to indicate whether the terminal needs monitoring and scheduling in OnDuration, PBPSS is also used to instruct the terminal to perform CSI measurement and a CSI report. Through CSI measurement and reporting, the network device can know the specific status of the downlink channel, so that it can use more appropriate parameters for scheduling in On Duration, thereby improving transmission efficiency and transmission speed. In this way, the terminal can enter a short sleep state after receiving/sending data quickly, thereby saving power consumption. The first PBPSS is a specific power saving signal, such as WUS, the first CSI-RS, and is a channel measurement reference signal for the first PBPSS to indicate triggering for a certain channel measurement.

Based on the method provided in the first aspect, the terminal can determine the first CSI-RS trigger offset value, and the first CSI-RS trigger offset value is less than or equal to the time slot of the PDCCH-based power saving signal and the aperiodic CSI- The time slot difference between the time slots where the RS is located, so the first CSI-RS trigger offset value can also be understood as the difference between the time slot where the PDCCH-based power saving signal is located and the time slot where the aperiodic CSI-RS triggered by the PDCCH is located. The minimum time slot difference between. When the first CSI-RS trigger offset value offset is set to be large enough, first of all, the terminal can clearly know that the network device will not be within offset time slots after the time slot where the PDCCH-based power saving signal is sent by the network device. When sending CSI-RS signals, the terminal does not need to buffer data during this period, so the terminal can turn off the radio frequency module to save power consumption. Secondly, the terminal can reduce code speed and processing voltage, thereby saving power consumption.

With reference to the first aspect, in a first possible implementation manner of the first aspect, the terminal determining the first CSI-RS trigger offset value includes: the first CSI-RS trigger offset value is in the first CSI-RS resource group The smallest value among the trigger offset values of all CSI-RS resources, the first CSI-RS resource group is a group of resources configured by the network device for the terminal, and any resource in the first CSI-RS resource group is only triggered in the PBPSS.

In this implementation manner, the network device configures dedicated resources for the CSI-RS triggered by the PDCCH-based power saving signal, so that the offset between the PDCCH-based power saving signal and the aperiodic CSI-RS triggered by it is sufficiently large. After the PDCCH-based power saving signal is shifted by offset time slots, the terminal will not receive the CSI-RS transmission, and the RF module can be turned off to avoid unnecessary signal reception, and the terminal can reduce the code speed and reduce the processing voltage , So as to achieve the purpose of energy saving. And the resource can only be triggered in the power saving signal based on the PDCCH, and cannot be triggered in the PDCCH used for scheduling data. Specifically, the implementation manner of configuring the CSI-RS resource by the network device can refer to Embodiment 1 of the present application. Optionally, before the network device sends the configuration information to the terminal, the terminal may report the desired "first CSI-RS trigger offset value" to the network device.

With reference to the first aspect, in a second possible implementation manner of the first aspect, the terminal determining the first CSI-RS trigger offset value includes: the first CSI-RS trigger offset value is all associated with the first trigger state group The minimum value among the trigger offset values of the CSI-RS resources, the first trigger state group is a group of trigger states configured by the network device for the terminal, and any trigger state in the first trigger state group is only indicated in the PBPSS.

In this implementation, the network device defines a special triggering state (triggering state) for the CSI-RS triggered based on the PDCCH power saving signal, and each CSI triggering state is associated with a certain CSI-RS resource and CSI reporting configuration. The difference from the prior art is that the trigger state can only be indicated in the PDCCH-based power saving signal.

With reference to the first aspect, in a third possible implementation manner of the first aspect, the terminal determining the first CSI-RS trigger offset value includes: the first CSI-RS trigger offset value is the second trigger offset value, and The second trigger offset value is configured to the terminal by the network device; the second trigger offset value is only used for PBPSS.

In this implementation manner, the resources and triggering state for triggering CSI-RS are configured according to the prior art, that is, the configuration of the PDCCH for scheduling data transmission and the configuration of the CSI measurement triggered by the PDCCH-based power saving signal are the same. In order to ensure that the triggering offset is sufficiently large, the network device configures a second trigger offset value for the terminal, and the second trigger offset value can only be used when the aperiodic CSI-RS signal is triggered in the power saving signal based on the PDCCH.

With reference to the third possible implementation manner of the first aspect, in the fourth possible implementation manner of the first aspect, the terminal determining the first CSI-RS trigger offset value includes: the terminal is configured by the network device with the second trigger offset The first CSI-RS trigger offset value is the larger of the second trigger offset value and the third trigger offset value; the third trigger offset value is the smallest K0 value indicated by the network device; where, K0 is the time slot difference between the time slot where the PDCCH (scheduling PDCCH, SPDCCH) used for scheduling data is located and the time slot where the physical downlink data channel PDSCH scheduled by the SPDCCH is located.

In this implementation, the minimum K0 value indicated by the network device is multiplexed into the radio network temporary identifier RNTI (Radio Network Temporary Identifier) of "PDCCH-based power saving signal", and the minimum K0 value is used as the third trigger The offset value offset3. At the same time, consider that the network device configures a second trigger offset value offset2 for the terminal. The function of the second trigger offset value is to assume that the terminal will not receive the RS before the PDCCH-based power saving signal is offset by 2 time slots. Send; configuration considerations for the second trigger offset value: PDCCH decoding time, which may require the terminal to turn on additional hardware and software processing time after decoding; the configuration method of the second trigger offset value: may be protocol provisions or network configuration. Due to the larger offset setting, the terminal can reduce code speed and processing voltage, thereby saving power consumption, so the first CSI-RS trigger offset value should be the second trigger offset value and the third trigger offset value The larger value in.

With reference to the fourth possible implementation manner of the first aspect, in the fifth possible implementation manner of the first aspect, the terminal determining the first CSI-RS trigger offset value includes: the first CSI-RS trigger offset value Is the smaller one of the third trigger offset value and the fourth trigger offset value; where the fourth trigger offset value is the time slot difference between the time slot where the PBPSS is located and the OnDuration start time slot.

In this implementation, the minimum K0 value indicated by the network device is multiplexed into the wireless network temporary identification RNTI of the "PDCCH-based power saving signal", and the minimum K0 value is used as the third trigger offset value, while considering To the fourth trigger offset value, here the fourth trigger offset value refers to the time slot difference between the time slot where the PDCCH-based power saving signal is located and the OnDuration start time slot. When the third trigger offset value is less than the fourth trigger offset value, because the CSI-RS triggered by the power saving signal is after the third trigger offset value, the first CSI-RS trigger offset value is the third trigger The offset value. When the third trigger offset value is greater than the fourth trigger offset value, the CSI-RS triggered based on the power saving signal of the PDCCH can be sent after the terminal enters On Duration. This can help the terminal to track the channel or perform operations such as beam management by receiving the CSI-RS faster, which is helpful to improve performance, so the first CSI-RS trigger offset value is the third trigger offset value. In summary, the first CSI-RS trigger offset value is the smaller of the third trigger offset value and the fourth trigger offset value.

With reference to the fifth possible implementation manner of the first aspect, in the sixth possible implementation manner of the first aspect, the terminal determining the first CSI-RS trigger offset value includes: when the second trigger offset value and the second trigger offset value When the three trigger offset values are all less than the fourth trigger offset value, the first CSI-RS trigger offset value is the larger of the second trigger offset value and the third trigger offset value; otherwise, the first CSI-RS trigger offset value The RS trigger offset value is the fourth trigger offset value.

In this implementation manner, the second trigger offset value offset2, the third trigger offset value offset3, and the fourth trigger offset value offset4 are considered at the same time. There are three cases to consider at this time: when the second trigger offset value and the third trigger offset value are both less than the fourth trigger offset value, this situation is similar to the third possible implementation, the first CSI-RS The trigger offset value should be the larger of the second trigger offset value and the third trigger offset value. When the second trigger offset value and the third trigger offset value are both greater than the fourth trigger offset value, this situation is similar to the fourth possible implementation, and the first CSI-RS trigger offset value should be the first Four trigger offset value. When one of the second trigger offset value and the third trigger offset value is greater than the fourth trigger offset value, and one is less than the fourth trigger offset value, the second trigger offset value is smaller than the fourth trigger offset value, and the first The three trigger offset value is greater than the fourth trigger offset value as an example. When only the second trigger offset and the third trigger offset value are considered, take the larger value of the two, that is, the third trigger offset value. Consider the third trigger offset value and the fourth trigger offset value. At this time, since the third trigger offset value is greater than the fourth trigger offset value, the fourth trigger offset value should be taken as the first CSI-RS trigger offset value. In summary, the first CSI-RS trigger offset value can be determined by the following formula: min{max{offset2,offset3},offset4}.

The minimum time slot difference between. When the first CSI-RS trigger offset value offset is set to be large enough, first of all, the terminal can clearly know that the network device will not be within offset time slots after the time slot where the PDCCH-based power saving signal is sent by the network device.

Detailed ways

To facilitate the understanding of the methods provided in the embodiments of the present application, before introducing the embodiments of the present application, some terms involved in the embodiments of the present application are explained:

The physical downlink control channel (PDCCH) is mainly used to carry downlink control information (DCI). DCI can include public control information (such as system information, etc.) and user-specific information (such as downlink resources) Allocation instructions, uplink scheduling, random access response, uplink power control parameters, etc.) etc. The PDCCH can schedule data channels through the DCI carried by it. For example, DCI can be used to indicate the transmission parameters of the data channel (such as the time domain resource location of the data channel, etc.). Before the data channel is transmitted, the network device can send the PDCCH to the terminal. After receiving the PDCCH, the terminal can demodulate the DCI in the PDCCH first, and then transmit the data channel on the time domain resource location indicated by the DCI.

The data channel can be used to carry data. According to the data carried on the data channel, the 3GPP protocol divides the data channel into: physical uplink shared channel (PUSCH) (or called uplink data channel) and physical downlink channel (PDSCH) (Alternatively called the downlink data channel). Among them, the PUSCH is used to carry data sent from the terminal to the network device (or referred to as uplink data), and the PDSCH is used to carry data sent from the network device to the terminal (or referred to as downlink data).

Further, the PDCCH can also trigger the transmission of aperiodic channel state information reference signal (aperiodic channel state information reference signal, aperiodic CSI-RS) through the DCI carried by it, and/or the PDCCH can trigger the aperiodic sounding reference through the DCI carried by it Signal (sounding reference signal, SRS) transmission, etc. Taking the PDCCH to trigger the transmission of CSI-RS as an example, the network device can send the PDCCH to the terminal. The DCI carried by the PDCCH is used to trigger the transmission of CSI-RS. After receiving the PDCCH, the terminal can demodulate the DCI in the PDCCH according to the instructions of the DCI The triggering state (triggering state) determines the triggered CSI-RS resource, and determines the time domain resource location of the resource according to the configuration information of the resource, and finally receives the CSI-RS sent by the network device at the corresponding time domain resource location.

The CSI-RS is used for the terminal to measure the channel state between the terminal and the network device. The CSI-RS may include one or more channel state measurement resources. For example, the network device may send DCI for triggering CSI-RS to the terminal, and the terminal determines the triggered CSI-RS resource according to the triggering state indicated by the DCI, and determines the time domain resource location of the resource according to the configuration information of the resource. The terminal receives the CSI-RS sent by the network device according to the time domain resource position of the CSI-RS, measures the channel state measurement resources included in the CSI-RS, and reports channel state information (CSI-RS) to the network device according to the measurement results. ).

SRS is used for network equipment to measure channel information between it and the terminal. For example, the network device can send the DCI used to trigger the SRS to the terminal, and the terminal determines the time domain resource location of the triggered SRS resource according to the triggering state indicated by the DCI. At the time domain resource location of the SRS, some or all of the terminal’s antennas are used. Send SRS to network equipment. The network device receives the SRS, and measures the channel information between it and the terminal according to the received SRS.

Among them, one PDCCH may occupy one or more symbols in one slot. The embodiment of the present application does not limit the time slot occupied by the PDCCH, and the starting position of the symbols occupied by the PDCCH in the time slot and the number of symbols.

Discontinuous reception (DRX) can be called discontinuous reception (connected discontinuous reception, C-DRX) in a connected state. The basic principle of C-DRX is that a terminal in the RRC_CONNECTED state is configured with a C-DRX cycle. Figure 1 is a schematic diagram of the C-DRX cycle. As shown in Figure 1, the C-DRX cycle can be composed of an activation period "On Duration" and a sleep period "Opportunity for DRX". During the “On Duration” time, the terminal monitors and receives the physical downlink control channel (PDCCH); during the “Opportunity for DRX” time, the terminal does not receive the PDCCH to reduce power consumption. Among them, the cycle size of the C-DRX and the length of the activation period and the sleep period are configured to the terminal by the network device.

Optionally, when the PDCCH is used to schedule the data channel, the network device configures the terminal in advance with scheduling information monitoring occasion, and the terminal starts to monitor the PDCCH when the scheduling information monitoring opportunity configured by the network device arrives. Among them, the scheduling information monitoring opportunity can be configured to the terminal periodically, so that the terminal periodically monitors the PDCCH.

Wherein, the time slot occupied by the PDCCH and the time slot occupied by the data channel scheduled by the PDCCH and/or the triggered reference signal may be the same or different. In the 3GPP protocol, according to the time slots occupied by the PDCCH and the time slots occupied by the PDCCH scheduling data channel and/or the triggered reference signal, the scheduling mode of the terminal is divided into: single slot scheduling, cross-slot scheduling. Time slot scheduling (cross-slot scheduling). Wherein, simultaneous slot scheduling may mean that the PDCCH and its scheduled data channel and/or triggered reference signal are located in the same time slot, and cross-slot scheduling may mean that the PDCCH and its scheduled data channel and/or triggered reference signal are located in different time slots, for example :

When the PDCCH is used to schedule the PDSCH, the PDCCH and the scheduled PDSCH can be in the same time slot, that is, simultaneous slot scheduling, or in different time slots, that is, cross-slot scheduling. In the 3GPP protocol, the K0 value indicates whether the PDCCH and its scheduled PDSCH are scheduled at the same time or across time slots. Among them, the K0 value is the time slot difference between the time slot occupied by the PDCCH and the time slot occupied by the scheduled PDSCH. The value of K0 has a value set, which is configured by the network device through RRC signaling For the terminal, for example, it can be {0, 1, 2...}. If K0=0, it means that PDCCH and PDSCH are in the same time slot, that is, "simultaneous slot scheduling". If K0>0, it means that PDCCH and PDSCH are not in the same time slot, that is, "cross-slot scheduling". The network device can directly indicate the K0 value to the terminal, or the network device configures a time domain resource allocation (TDRA) table for the terminal. The TDRA table includes the index value (index) and the K0 value corresponding to the index value. , The network device can indirectly indicate the K0 value to the terminal by indicating the index value to the terminal.

For example, Table 1 below is a schematic diagram of the TDRA table configured by the network device for the terminal when the PDCCH schedules the PDSCH. The TDRA table includes the corresponding relationship between the index value and the K0 value. As shown in Table 1, when the index value is 0, the K0 value When the index value is 1, the K0 value is 1; when the index value is 2, the K0 value is 2. When the network device schedules the PDSCH to the terminal through the PDCCH, the network device can configure the TDRA table shown in the terminal configuration table 1. Subsequently, if the network device indicates the index value of 1 to the terminal, the terminal can use the index value of 1 as the index and query the table 1. It is determined that the K0 value corresponding to the index value 1 is 1, and the PDCCH and PDSCH are in different time slots, that is, cross-slot scheduling.

When the PDCCH is used to schedule the PUSCH, the PDCCH and the scheduled PUSCH can be in the same time slot, that is, simultaneous slot scheduling, or in different time slots, that is, cross-slot scheduling. In the 3GPP protocol, the K2 value is used to indicate whether the PDCCH and its scheduled PUSCH are scheduled at the same time or across time slots. Among them, the K2 value is the time slot difference between the time slot occupied by the PDCCH and the time slot occupied by the scheduled PUSCH. The value of K2 has a value set, which is configured by the network device to the terminal, for example It can be {0, 1, 2...}. If K2=0, it means that the PDCCH and PUSCH are in the same time slot, that is, "simultaneous slot scheduling". If K2>0, it means that PDCCH and PUSCH are not in the same time slot, that is, "cross-slot scheduling". The network device can directly indicate the K2 value to the terminal, or the network device configures a TDRA table for the terminal. The TDRA table includes an index value (index) and a K2 value corresponding to the index value. The network device can indicate the index value to the terminal. The K2 value is indirectly indicated to the terminal.

For example, Table 2 below is a schematic diagram of the TDRA table configured by the network device for the terminal when the PDCCH schedules the PUSCH. The TDRA table includes the correspondence between the index value and the K2 value. As shown in Table 2, when the index value is 0, the K2 value Is 0; when the index value is 1, the K2 value is 2. When the network device schedules the PUSCH to the terminal through the PDCCH, the network device can configure the TDRA table shown in Table 2 to the terminal. Subsequently, if the network device indicates an index value of 1 to the terminal, the terminal can use the index value of 1 as the index and query the table Second, determine that the K2 value corresponding to the index value 1 is 2, the PDCCH and the PDSCH are in different time slots, and there is a difference of 2 time slots between the two, that is, cross-slot scheduling.

It should be noted that Table 1 and Table 2 are only exemplary tables. In addition to the content shown in the table, Table 1 and Table 2 may also include other content, such as starting and length indication values (starting and length). incdication value), mapping type (mapping type), etc., this application does not limit this.

When the PDCCH is used to trigger the CSI-RS, the PDCCH and the CSI-RS triggered by it can be in the same time slot or in different time slots. In the 3GPP protocol, the aperiodic CSI-RS triggering offset is used to determine that the PDCCH and the CSI-RS triggered by it are in the same slot or in different time slots. Among them, the aperiodic CSI-RS trigger offset value is the time slot difference between the time slot occupied by the PDCCH and the time slot occupied by the scheduled CSI-RS, the aperiodic CSI-RS trigger offset value can be determined by the network device Configured to the terminal, if the aperiodic CSI-RS trigger offset value is equal to 0, it means that the PDCCH and the triggered CSI-RS are in the same time slot. If the aperiodic CSI-RS trigger offset value is greater than 0, it means that the PDCCH and the triggered CSI-RS are in different time slots.

When the PDCCH is used to trigger the SRS, the PDCCH and the triggered SRS can be in the same time slot or in different time slots. In the 3GPP protocol, it is determined by aperiodic SRS triggering offset (triggering offset) that the PDCCH and the triggered SRS are in the same slot or in different time slots. Among them, the aperiodic SRS trigger offset value is the time slot difference between the time slot occupied by the PDCCH and the time slot occupied by the scheduled SRS. The aperiodic SRS trigger offset value can be configured by the network equipment to the terminal, if The aperiodic SRS trigger offset value is equal to 0, indicating that the PDCCH and the triggered SRS are in the same time slot. If the aperiodic SRS trigger offset value is greater than 0, it means that the PDCCH and the triggered SRS are in different time slots.

At present, in order to reduce the power consumption of the terminal, optimization can be carried out from two aspects: one is to improve the data transmission efficiency when there is business load (that is, there is data to be transmitted); the other is to improve the data transmission efficiency when there is no business load (that is, when there is no data to be transmitted). ), reduce the energy consumption of the terminal. Regarding the second point, it is mentioned in the report of the International Telecommunication Union-Radiocommunication Sector (ITU-R) that the energy consumption of the terminal can be reduced by increasing the proportion of the terminal in the sleep state.

For example, as shown in Figure 2, within a C-DRX On Duration time, the terminal receives the PDCCH in the t1 period, as shown on the left side of Figure 2, if the terminal does not know whether there is simultaneous slot scheduling in the current time slot (as long as If the TDRA table configured by the network device includes K0=0, there may be simultaneous slot scheduling). In order to avoid data and/or signal loss, after receiving the PDCCH, the terminal must buffer the data and/or signal while decoding the PDCCH, as shown in Figure 2. During the t2 period shown on the left, the terminal needs to turn on its own radio frequency module at all times to buffer data and/or signals. If the terminal knows in advance that the PDCCH and the data channel are scheduled across time slots, as shown on the right side of Figure 2, there must be no data channel scheduled by the PDCCH and/or trigger reference signals in the current time slot, then the terminal is receiving the PDCCH Afterwards, in the process of decoding the PDCCH, you can turn off your own radio module without buffering any data and/or signals to achieve energy saving. As shown on the right side of Figure 2, the shaded part corresponding to the t2 period is the energy saved by the terminal. .

It can be seen from the above that when the terminal has no data service, the terminal should be placed in the "cross-slot scheduling" state to save power consumption (provided that all K0 meet K0>0); when the terminal has data service arrival At this time, the terminal should be in the state of "simultaneous slot scheduling" to ensure that the data transmission is completed quickly and to reduce time delay. In order to enable the terminal's scheduling mode to quickly match the terminal's current service type, dynamic signaling can be used to indicate the switching of the scheduling mode, for example, to indicate a "valid" subset of the TDRA table. For example, there are 3 rows in the table, among which the first row is K0=0, and the last two rows are K0>0. You can indicate that only the last two lines are valid. Alternatively, the network device implements the configuration of multiple TDRA tables, dynamically indicating which table is "valid". For example, if two tables are configured, K0=0 exists in the first table, and all K0 in the second table satisfy K0>=2. Or, the network device dynamically indicates a minimum K0 value. For example, the minimum dynamic indication K0 is 3 and so on.

As the 5G NR (new radio) system needs to support larger bandwidth, higher transmission rate, and wider coverage than the 4G LTE (Long Term Evolution) system, the power consumption of NR terminals is greater than that of LTE terminals. . In order to ensure a good user experience, 3GPP (3rd Generation Partnership Project) has set up a special project in Rel-16 for the topic of terminal power consumption saving, and studied optimization schemes for reducing terminal power consumption.

In the power saving subject, there are the following solutions: network equipment can send to the terminal a power saving signal (power saving signal/channel) based on the physical downlink control channel (PDCCH), as shown in Figure 3, based on the PDCCH The power saving signal can be before the On Duration of a C-DRX, and the power saving signal can be used to instruct the terminal to receive discontinuous reception (connected discontinuous reception, C-CRX) in the next one or more connected states. In a cycle (cycle), it is in a sleep state or an awake state; the solid line box in FIG. 3 represents On Duration when the terminal is in the awake state, and the dashed box represents On Duration when the terminal is in the sleep state. After receiving the power saving signal, the terminal can be in a sleep state or in an awake state according to the indication of the power saving signal, so that some circuits of the terminal can be turned off in the sleep state to reduce the energy consumption of the terminal.

In addition, the above-mentioned "PDCCH-based power saving signal" can also be used to indicate other functions, such as instructing the terminal to perform CSI (channel state) measurement. As shown in FIG. 4, the power saving signal based on PDCCH can trigger an aperiodic CSI-RS and a CSI report. Through CSI measurement and reporting, network equipment can know the specific status of the downlink channel, so that more appropriate parameters (such as MCS (modulation and coding scheme), precoding matrix, etc.) can be used in On Duration. Scheduling, thereby improving transmission efficiency and transmission speed. In this way, the terminal can enter a short sleep state after receiving/sending data quickly, thereby saving power consumption.

It can be seen from the above that the time slot difference between the time slot occupied by the PDCCH and the time slot occupied by the triggered CSI-RS can be determined by the aperiodic CSI-RS triggering offset value (triggering offset). As shown in Figure 5, if the triggering offset of the CSI-RS configured by the network device is too small, to avoid data and/or signal loss, after the terminal receives the PDCCH-based power-saving signal, it decodes the PDCCH-based power-saving signal At the same time, it is necessary to turn on its own radio frequency module at all times to buffer the CSI-RS signal, resulting in waste of terminal power consumption. To solve this problem, an embodiment of the present application provides a method for indicating channel state measurement parameters to determine a first CSI-RS trigger offset value for the PDCCH-based power saving signal, so that the PDCCH-based power saving signal is The time slot difference between the slot and the time slot where the triggered aperiodic CSI-RS is located is not less than the first CSI-RS trigger offset value. Because the first CSI-RS trigger offset value is less than or equal to the time slot difference between the time slot where the PDCCH-based power saving signal is located and the time slot where the triggered aperiodic CSI-RS is located, the first CSI-RS trigger is The offset value can be understood as the minimum time slot difference between the time slot where the PDCCH-based power saving signal is located and the time slot where the triggered aperiodic CSI-RS is located, so the above is determined by the PDCCH-based power saving signal A first CSI-RS triggering offset value may also be referred to as a minimum CSI-RS triggering offset value (minimum CSI-RS triggering offset), where the minimum CSI-RS triggering offset value may be {0, 1, 2…….}. When the minimum CSI-RS trigger offset value offset1 is greater than zero, the terminal can clearly know that the network device will not send CSI-RS within offset1 time slot after the time slot where the network device sends the PDCCH-based power saving signal. Signal, the terminal does not need to buffer data during this period of time, so the terminal can turn off the radio frequency module to save power consumption. In addition, the terminal can decode the PDCCH-based power saving signal within this time range. When the offset1 is set to be large enough, the terminal can reduce the code speed and processing voltage, thereby saving power consumption. After the terminal successfully decodes the power saving signal, it can know the specific time slot where the CSI-RS triggered by the power saving signal is located, so as to remove the actual time slot in which the power saving signal triggers the CSI-RS to receive the CSI-RS. In actual scenarios, there may be a situation where offset1=0. Although it cannot play a role in saving power consumption for the terminal, the network device can trigger the transmission of CSI-RS faster so that the terminal can receive the reference signal as soon as possible. Achieve faster channel tracking or beam management.

It should be noted that the first CSI-RS trigger offset value, the minimum CSI-RS trigger offset, and offset1 mentioned in the embodiments of this application document have the same meaning and are only different expressions in different scenarios. .

Fig. 8 is a flow chart of signaling interaction between network equipment triggering CSI-RS and terminal CSI reporting in the prior art. As shown in Fig. 8, the method may include:

Step 801: The network device generates configuration information.

Step 802: The network device configures aperiodic CSI-RS resources for the terminal.

The configuration of the CSI-ResourceConfig is indicated in the RRC signaling configuration IE, and the recourceType is configured as aperiodic.

Step 803: The network device configures a group of triggering states for the terminal.

Through IE, CSI-SemiPersistentOnPUSCH-TriggerStateList configures a set of trigger states, where each trigger state is associated with a CSI report configuration CSI-ReportConfig, and each CSI-ReportConfig is associated with one or more CSI-RS resources.

Step 804: The network device generates a PDCCH for scheduling PUSCH.

In the prior art, when a network device triggers a CSI-RS signal, it can only be indicated in the PDCCH for scheduling the uplink data PUSCH.

Step 805: The network device sends the PDCCH for scheduling the PUSCH to indicate a trigger state.

The network device sends a field in the DCI in the PDCCH for scheduling the PUSCH to indicate an index of a trigger state.

Step 806: The terminal receives and analyzes the PDCCH of the scheduled PUSCH.

Step 807: The network device generates a corresponding CSI-RS signal.

Step 808: The network device sends the corresponding CSI-RS according to the indication of the PDCCH for scheduling the PUSCH.

CSI-RS is triggered by a field called CSI request (CSI request) in scheduling DCI.

Step 809: The terminal receives the CSI-RS according to the related configuration corresponding to the trigger state, performs channel estimation, and generates CSI report information.

Step 810: The terminal sends CSI report information to the network device.

The CSI report information is carried in the scheduled PUSCH.

Step 811: The network device analyzes the CSI reported information, and determines subsequent PDSCH scheduling parameters.

In the prior art, before the network device triggers the CSI-RS signal through the PDCCH, the network device first configures the terminal with aperiodic CSI-RS resources and a set of trigger states. Each trigger state is associated with a CSI report configuration CSI-ReportConfig. One CSI-ReportConfig is associated with one or more CSI-RS resources.

Exemplarily, in the prior art, the process of triggering CSI-RS resources by a network device may be:

The network equipment configures a group of 5 CSI-RS resources with index=0 to 4 for the terminal through RRC signaling;

The network equipment configures a group of triggering states for the terminal through RRC signaling, state=0~1, where state 0 is associated with three resources with index=0~2, and state 1 is associated with two resources with index=3~4;

The network device sends the DCI for scheduling data transmission to the terminal. There is a field in the DCI indicating that triggering state=1, then the network device sends two CSI-RS resources with index=3 to 4 at the corresponding position.

In the first embodiment of the present application, on the basis of the prior art, a network device configures dedicated resources for the CSI-RS triggered by the PDCCH-based power saving signal, so that the PDCCH-based power saving signal and its triggered aperiodic CSI-RS The offset between is large enough to avoid unnecessary signal reception, so as to achieve the purpose of energy saving.

Specifically, the implementation manner of configuring CSI-RS resources by the network device can refer to the following manner 1 to manner 3.

Manner 1: Define a set of CSI-RS resources, and the CSI-RS resources can only be triggered in the power saving signal based on the PDCCH, and cannot be triggered in the PDCCH for scheduling data transmission (scheduling).

Exemplarily, the power saving signal may be wake-up signal (WUS), which is sent before the On Duration of a C-DRX, and is used to indicate whether the terminal needs to be in the next one or more C-DRX cycles. PDCCH for monitoring scheduling data. The dedicated CSI-RS resource configured by the network device for the terminal can be defined as AP-CSI-RS-ResourceSet-ForPowerSaving. The network device configures 10 resources with index=0-9 for the terminal, where index=0-6 indicates normal CSI-RS (that is, CSI-RS that can be triggered by the PDCCH of scheduled data according to the prior art), offset={0 ,1,2}; index=7-9 indicates AP-CSI-RS-ResourceSet-ForPowerSaving, offset={3,4,5}. In the PDCCH for scheduling data transmission, only resources with index=0 to 6 can be triggered; in the PDCCH-based power saving signal, only resources with index=7 to 9 can be triggered. If the network device enables the "power saving signal" function, even if the resources with index=7-9 have been configured, these resources cannot be indicated or used.

Optionally, before the network device sends the configuration information to the terminal, the terminal may report the desired "minimum CSI-RS trigger offset value" to the network device, and this value is exemplarily represented by offset1.

Method 2: Define AP-CSI-RS-ResourceSet-ForPowerSaving. The configuration information of AP-CSI-RS-ResourceSet-ForPowerSaving is included in the enable information of the PDCCH-based power saving signal.

Exemplarily, the configuration mode of the PDCCH-based power saving signal may be:

The signaling is explained as follows: PowerSavingConfig is the configuration signaling for enabling the terminal power saving function, which includes the power saving signal configuration signaling PowerSavingSignalConfig based on the PDCCH.

PowerSavingSignalConfig may include:

SearchSpaceIndex: the index value of the search space for monitoring the "power saving signal", that is, in which search space the "power saving signal" is to be monitored;

IndicatedFunctions: What are the functions to be indicated in the "power saving signal", for example, it may include at least "indicating whether to monitor scheduling in On Duration", and may also include "whether aperiodic CSI-RS measurement can be triggered". In the embodiment of this application, both of these functions exist.

AP-CSI-RS-ResourceSet-ForPowerSaving is a set of resources configured by network equipment for "PDCCH-based power saving signal".

AP-CSI-RS-Resources-ForPowerSaving is a specific set of resource configurations, where each configuration may include UsedSequence (used sequence) and offset value.

aperiodicTriggeringOffset INTEGER(0..6): is the configured offset value. Optionally, before the network device sends configuration information to the terminal, the terminal can report the expected "minimum CSI-RS trigger offset value" to the network device. As long as the offset value is configured to be large enough, it can be guaranteed that the terminal will be able to decode successfully within the offset time slots after the PDCCH time slot.

Manner 3: The enabling information of the power saving signal based on the PDCCH includes association information, which is associated with the configuration information of AP-CSI-RS-ResourceSet-ForPowerSaving.

AP-CSI-RS-Resources-ForPowerSaving SEQUENCE OF resourceID: the configuration information associated with AP-CSI-RS-ResourceSet-ForPowerSaving through resourceID.

AP-CSI-RS-Resource-ForPowerSaving: Contains AP-CSI-RS-ResourceSet-For PowerSaving configuration information.

Optionally, before the network device sends the configuration information to the terminal, the terminal may report the expected "minimum CSI-RS trigger offset value" to the network device, and this value is exemplarily represented by offset1.

In summary, in the first embodiment, the network device can configure dedicated resources for the CSI-RS triggered by the PDCCH-based power-saving signal through any of the above methods, so that the PDCCH-based power-saving signal and the The offset between the triggered aperiodic CSI-RS is sufficiently large. For the terminal, since the terminal knows that the network device will definitely not trigger the transmission of CSI-RS before the offset slot after the time slot where the PDCCH-based power saving signal is located, the terminal can not buffer data during this period of time, thereby To achieve the purpose of energy saving. In addition, the terminal can decode the PDCCH-based power saving signal in the offset time slots after the time slot where the PDCCH-based power saving signal is located. A larger offset value can reduce the speed of the terminal and reduce the processing voltage. Thereby saving power consumption. After the terminal successfully decodes the DCI of the power saving signal, it can know the specific time slot of the CSI-RS triggered by the power saving signal, so that the actual time slot of the CSI-RS triggered by the power saving signal to receive the CSI-RS.

In the second embodiment of the present application, the network device defines a special triggering state (triggering state) for the CSI-RS triggered based on the PDCCH power saving signal.

As shown in FIG. 8, in the prior art, CSI-RS is triggered by a field called CSI request (CSI request) in scheduling DCI. This field actually does not directly indicate the CSI-RS resource, but indicates a CSI triggering state. The network device will configure a set of CSI triggering states for the terminal through the CSI-AperiodicTriggerStateList parameter, and each CSI triggering state will be associated with a certain CSI-RS resource and CSI reporting configuration. When the network device triggers a CSI measurement, the terminal will determine the CSI-RS resource that needs to be received according to the triggering state indicated by the network device, and report the relevant configuration of the CSI feedback information. In the prior art, the network device configures a set of triggering states for the terminal at most.

The method of this embodiment is to define a set of new trigger states for the CSI-RS triggered by the PDCCH power saving signal. Exemplarily, the configuration signaling may be called CSI-AperiodicTriggerStateListForPowerSaving.

Exemplarily, the network device configures 10 resources with index=0-9, where index=0-6 is the CSI-RS with offset=0; index=7-9 is the CSI-RS with offset=1, and is defined as follows :

When the triggering state=0 is indicated in the PDCCH, if the PDCCH is a PDCCH for scheduling data transmission, the CSI-RS with index=0 will be triggered; if the PDCCH is a "power saving signal based on PDCCH", the trigger is CSI-RS with index=7.

The difference with the prior art is that, in this embodiment, if the triggering state indicated by the scheduling DCI is 0, the trigger is the CSI-RS resource corresponding to the trigger state 0 configured by the parameter CSI-AperiodicTriggerStateList, and the CSI-RS resource that reports the CSI feedback information. Related configuration; if the triggering state indicated by the PDCCH power saving signal is 0, the trigger is the CSI-RS resource corresponding to the trigger state 0 configured by the parameter CSI-AperiodicTriggerStateListForPowerSaving, and the related configuration for reporting CSI feedback information.

Optionally, before the network device sends the configuration information to the terminal, the terminal may report the expected "minimum CSI-RS trigger offset value" to the network device.

In the third embodiment of the present application, the CSI-RS and triggering state are configured according to the prior art, that is, the configuration of the PDCCH for scheduling data transmission and the configuration of the CSI measurement triggered by the power saving signal based on the PDCCH is the same configuration. In order to ensure that the triggering offset is large enough, the network device configures a second CSI-RS trigger offset value for the terminal, that is, the minimum CSI-RS trigger offset value is the second trigger offset value, and the second CSI-RS trigger offset The value can only be used when the aperiodic CSI-RS signal is triggered in the PDCCH-based power saving signal, and cannot be used when the aperiodic CSI-RS signal is triggered by the PDCCH for scheduling data transmission.

Exemplarily, as shown in FIG. 9A, the network device configures a second CSI-RS trigger offset value for the terminal with offset2=1, and the power saving signal is wake-up signal (WUS), then WUS triggers The time slot where the reference signal is located is the first time slot and subsequent time slots after the time slot where the WUS DCI is located. For the terminal, since the terminal knows that the network device will definitely not trigger the transmission of CSI-RS before the first time slot after the time slot where the WUS DCI is located, the terminal can not buffer data during this time, thereby achieving the purpose of energy saving. After the terminal successfully decodes the WUS DCI, it can know the specific time slot where the CSI-RS triggered by the WUS is located, and then go to the actual time slot where the WUS triggers the CSI-RS to receive the CSI-RS.

In addition, the larger the offset2 is, the slower the terminal can decode WUS PDCCH processing speed, and the slower decoding speed means that the terminal consumes lower power consumption. It is sufficient to ensure that WUS DCI is successfully decoded before WUS triggers the minimum trigger offset and DRX On Duration of RS.

In the prior art, in order to avoid waste of power consumption caused by the terminal having to always turn on the radio frequency module because it does not know whether the current time slot has a scheduling. The network device can semi-statically configure the "K0/K2/CSI-RS trigger offset value/SRS trigger offset value" for the terminal through the RRC signaling to the "available minimum value", that is, the minimum K0 value of the network configuration (minimum K0), the smallest K2 value (minimum K2), the smallest aperiodic CSI-RS trigger offset value (minimum Aperiodic CSI-RS triggering offset), or the smallest aperiodic SRS trigger offset value (minimum aperiodic SRS triggering offset) . These "available minimum values" may be configured for each cell, or may be configured for each BWP (Bandwidth part).

The difference with the existing network equipment in the prior art is that the terminal RRC is semi-statically configured or dynamically indicating the "currently available minimum value" of "K0/K2/CSI-RS trigger offset value/SRS trigger offset value". The minimum CSI-RS trigger offset value in this embodiment is only used for the power saving signal based on the PDCCH, and cannot be used for the PDCCH for scheduling data transmission.

Optionally, the value of offset2 may be included in the configuration information of the power saving signal based on the PDCCH and configured.

Optionally, before the network side sends the configuration information to the terminal, the terminal may report the desired "minimum CSI-RS trigger offset value" to the network side.

In some cases, in order to achieve faster channel tracking, the terminal needs the network device to quickly trigger the CSI-RS to perform the channel state test. At this time, the value of offset2 may be less than the time for the terminal to decode WUS DCI. Therefore, before the decoding is successful, the network The device still needs to trigger CSI-RS transmission according to the position indicated by off2. Although the power consumption of WUS detection is high, the network device can trigger the transmission of CSI-RS faster, so that the terminal can receive the reference signal as soon as possible. Can realize faster channel tracking or beam management.

Exemplarily, as shown in FIG. 9B, taking offset2=0 as an example, the minimum CSI-RS trigger offset value for WUS to trigger CSI-RS is 0. Then the time slot where the reference signal triggered by WUS is located is the time slot where the WUS DCI is located or the time slot after the time slot where the WUS DCI is located. For the terminal, since it is impossible to know whether the CSI-RS triggered by the WUS is triggered at the same time or across the time slot before the WUS DCI is successfully decoded, the terminal starts to buffer data when receiving the WUS signal.

In this embodiment, offset2 can be an integer or a length of time. When offset2 is an integer, it means simultaneous slot scheduling or cross-slot scheduling. For example, offset2=0 means that the time slot of the reference signal triggered by WUS is the time slot of WUS DCI or the time slot after the time slot of WUS DCI, offset2= 1 indicates that the CSI-RS triggered by WUS is in the next time slot of the time slot where the WUS DCI is located or the time slot after the next time slot. Offset2 may also be a time length, such as a symbol level, such as 10 symbols, and the terminal assumes that the WUS-triggered CSI-RS transmission will not be received within 10 symbols after the WUS monitoring moment.

In the fourth embodiment of the present application, the smallest K0 value indicated by the network device is called offset3, and offset3 is multiplexed into the radio network temporary identifier RNTI (Radio Network Temporary Identifier) of the "PDCCH-based power saving signal", that is, "based on The "minimum CSI-RS trigger offset value" of the "PDCCH power saving signal" triggering the CSI-RS is offset3. The difference between this embodiment and the third embodiment is that offset3 can be used for both the PDCCH-based power saving signal and the PDCCH for scheduling data transmission.

Exemplarily, the power consumption saving signal in the embodiment of the present application may be based on PDCCH. If it is a power saving signal based on PDCCH, a new RNTI is introduced, such as PS-RNTI, then the cyclic redundancy check (CRC, Cyclic redundancy check) of the power saving signal based on PDCCH is scrambled by PS-RNTI of.

For another example, the power saving signal in the embodiment of the present application may be wake-up signal (WUS). If the power saving signal is called WUS, and a WUS-RNTI is introduced, then WUS is a PDCCH scrambled by WUS-RNTI.

In this embodiment, the power consumption saving signal is WUS as an example for description.

As mentioned above, in the prior art, the network can semi-statically configure the "per-Cell" or "per-BWP" or "per-UE" "K0/K2/CSI-RS trigger offset" for the terminal through RRC signaling. Value/SRS trigger offset value" "Available minimum value", that is, the network configuration minimum K0 value (minimum K0), minimum K2 value (minimum K2), minimum aperiodic CSI-RS trigger offset value ( minimum Aperiodic CSI-RS triggering offset, or minimum aperiodic SRS triggering offset (minimum aperiodic SRS triggering offset). Note that for one value of "K0/K2/CSI-RS trigger offset value/SRS trigger offset value", the network can configure one or more "available minimum values", if the network is configured with multiple "available Minimum value", the network needs to indicate that one of the values is the default value, or the standard determines that one of the multiple "available minimum values" configured according to certain rules is the default value, for example, the smallest value among multiple values. The value is the default value. If the network is only configured with a "available minimum value", this value is the default value.

For one value of "K0/K2/CSI-RS trigger offset value/SRS trigger offset value", when the network configures one or more "available minimum values" through RRC signaling for the first time, the terminal will Use its default value as the "currently available minimum value". When the terminal wakes up from the sleep state (for example, enters DRX on duration), or after the terminal switches from one BWP to another BWP, the network can dynamically adjust the "currently available minimum value" through L1 signaling (for example, PDCCH).

In another possible implementation, WUS can dynamically indicate the "currently available minimum value".

In this embodiment, there are two ways to apply the minimum K0 value indicated by the network device to the scenario where WUS triggers an aperiodic RS:

Method 1: The method stipulated in the agreement

The standard stipulates that if the network configures the "available minimum value" for K0, and can dynamically adjust the "currently available minimum value" through L1 signaling, the currently available minimum value (ie minimum K0) is applied to the WUS trigger aperiodic The RS scenario, for example, is applicable to a scenario where WUS triggers a network device to send aperiodic CSI-RS, and/or a scenario where WUS triggers a terminal to send aperiodic SRS signals.

Exemplarily, the network device applies the currently available minimum K0 value to the scenario where WUS triggers the network device to send aperiodic CSI-RS. Assuming minimum K0=1, the network device will not use the aperiodic CSI-RS triggered by WUS It is sent in the same time slot as WUS, and the terminal does not expect to receive aperiodic CSI-RS triggered by WUS in the time slot of receiving WUS.

It should be noted that if the "currently available minimum value" is dynamically adjusted by the L1 signaling, the scenario where WUS triggers the CSI-RS should also use the updated "currently available minimum value".

Method 2: The way of network configuration. The network can choose to configure whether the smallest K0 value currently available applies to the scenario where WUS triggers RS. Specifically, the configuration method can be Method 1 or Method 2:

Manner 1: Indicate in the RRC configuration IE of the PDCCH-based power saving signal.

Exemplarily, the RRC configuration IE is as follows:

Method 2: When configuring the minimum value available for K0, configure the function.

Exemplarily, the following configuration information may exist in RRC signaling:

In this embodiment, the minimum K0 value indicated by the network device is referred to as offset3, and the minimum K0 value indicated by the network device can be applied to the scenario where WUS triggers CSI-RS through either of the above two methods. That is, the "minimum CSI-RS trigger offset value" for WUS to trigger CSI-RS is offset3. As a terminal, the terminal will not receive the CSI-RS triggered by WUS before the time slot indicated by {WUS time slot + offset2}.

Exemplarily, as shown in FIG. 10, when offset3=2, the time slot where the CSI-RS triggered by WUS is located is the second time slot or the time slot after the time slot where WUS DCI is located. For the terminal, since the terminal knows that the network device will definitely not trigger the transmission of CSI-RS before the second time slot after the time slot where the WUS DCI is located, the terminal can not buffer data during this time, thereby achieving the purpose of energy saving. After the terminal successfully decodes the WUS DCI, it can know the specific time slot where the CSI-RS triggered by the WUS is located, and then go to the actual time slot where the WUS triggers the CSI-RS to receive the CSI-RS.

In this embodiment, the network device uses the designated minimum K0 value as the "minimum CSI-RS trigger offset" for WUS to trigger the CSI-RS, and the power consumption of the WUS can be dynamically adjusted and detected by the dynamic indication of offset3.

In the fifth embodiment of the present application, the scenarios involved in the third and fourth embodiments are combined, and offset2 and offset3 are considered at the same time. The minimum K0 value indicated by the network device is called offset3, and offset3 is multiplexed into the "PDCCH-based power saving signal" wireless network temporary identification RNTI. At the same time, considering that the network device is "power saving based on PDCCH" "Signal" configuration "Second CSI-RS trigger offset value" offset2, if offset3<offset2, the "minimum CSI-RS trigger offset value" of WUS trigger CSI-RS is equal to offset2, otherwise, WUS triggers CSI-RS The "minimum CSI-RS trigger offset value" is equal to offset3, that is, the "minimum CSI-RS trigger offset value" of the WUS trigger CSI-RS is equal to the larger value of offset2 and offset3.

The offset2 in this embodiment is equivalent to the "second CSI-RS trigger offset value" configured by the network device to the terminal in the third embodiment of this application. The function of Offset2: The terminal assumes that it will not receive RS transmission before offset 2 time slots after WUS Occasion; the configuration consideration of offset2: PDCCH decoding time, after decoding, it may require the terminal to turn on additional hardware and software processing time; offset2 Configuration method: It can be protocol stipulation or network configuration.

Exemplarily, as shown in FIG. 11A, when offset3<offset2, such as offset2=1 and offset3=0, the "minimum CSI-RS trigger offset value" of the WUS trigger RS is equal to offset2. For the terminal, since the terminal knows that the network device will definitely not trigger the transmission of CSI-RS before the first time slot after the time slot where the WUS DCI is located, the terminal can not buffer data during this time, thereby achieving the purpose of energy saving. After the terminal successfully decodes the WUS DCI, it can know the specific time slot where the CSI-RS triggered by the WUS is located, and then go to the actual time slot where the WUS triggers the CSI-RS to receive the CSI-RS.

Exemplarily, as shown in FIG. 11B, when offset3>offset2, such as offset2=1 and offset3=2, the "minimum CSI-RS trigger offset value" of the WUS trigger RS is equal to offset3. For the terminal, since the terminal knows that the network device will definitely not trigger the transmission of CSI-RS before the second time slot after the time slot where the WUS DCI is located, the terminal can not buffer data during this time, thereby achieving the purpose of energy saving. After the terminal successfully decodes the WUS DCI, it can know the specific time slot where the CSI-RS triggered by the WUS is located, and then go to the actual time slot where the WUS triggers the CSI-RS to receive the CSI-RS.

Offset2 can be an integer, indicating simultaneous slot scheduling or cross-slot scheduling. For example, offset2=0 indicates that the time slot of the reference signal triggered by WUS is the time slot of WUS DCI or the time slot after the time slot of WUS DCI, offset2=1 Indicates that the RS triggered by WUS is in the next time slot of the time slot where the WUS DCI is located or the time slot after the next time slot. Offset2 may also be a time length, such as a symbol level, such as 10 symbols, and the terminal assumes that the WUS-triggered RS transmission will not be received after the WUS monitoring time is offset by 10 symbols. When offset2 represents a time length, replace offset3 with delta, which represents the time interval between the WUS monitoring moment and the start symbol of the time slot indicated by offset3.

Exemplarily, as shown in FIG. 12, offset2 represents a time length, and offset3=0 results in delta<offset2, so the "minimum CSI-RS trigger offset value" for WUS to trigger CSI-RS is equal to offset2. The terminal does not need to cache data during the period of offset2

In this embodiment, it is considered that the network device sets an offset2 for the terminal. At this time, regardless of the size of the offset3, the terminal does not need to cache data in advance within the offset2, which ensures that there is an upper limit for the power consumption of the terminal to detect WUS. On this basis, if offset3>offset2 or delta>offset2, the terminal can further reduce the processing speed of decoding WUS, and further save the power consumption of the terminal to detect WUS.

In Embodiment 6 of the present application, on the basis of Embodiment 4, an offset4 is considered. The minimum K0 value indicated by the network device is called offset3, and offset3 is multiplexed into the wireless network temporary identification RNTI of the "PDCCH-based power saving signal". At the same time, considering offset4, here offset4 refers to WUS and OnDuration If offset3>offset4, the "minimum CSI-RS trigger offset value" of WUS trigger CSI-RS is equal to offset4, otherwise, the "minimum CSI-RS trigger offset value" of WUS trigger CSI-RS is equal to offset3 That is, the "minimum CSI-RS trigger offset value" for WUS to trigger CSI-RS is equal to the smaller value of offset3 and offset4.

Exemplarily, as shown in FIG. 13A, when offset3<offset4, such as offset3=0 and offset4=3, the "minimum CSI-RS trigger offset value" for WUS to trigger the CSI-RS is equal to offset3=0. Then the time slot where the CSI-RS triggered by the WUS is located is the time slot where the WUS DCI is located or the time slot after the time slot where the WUS DCI is located. For the terminal, it is impossible to know whether the RS triggered by the WUS is triggered at the same time or across the time slot before the WUS DCI is successfully decoded, so the terminal needs to start buffering data when receiving the WUS signal.

Exemplarily, as shown in FIG. 13B, when offset3>offset4, such as offset3=4 and offset4=3, if the solution of the fourth embodiment is followed, the CSI-RS triggered by WUS can only be sent after offset3. In this embodiment, the "minimum CSI-RS trigger offset value" of the WUS-triggered CSI-RS is set to offset4, and the WUS-triggered CSI-RS can be sent after the terminal enters On Duration. This can help the terminal to track the channel or perform operations such as beam management by receiving the CSI-RS triggered by the WUS more quickly, which helps to improve the performance. In addition, in this embodiment, it is assumed that the terminal has successfully decoded WUS before entering OnDuration, so after entering OnDuration, the terminal only needs to trigger the actual time slot of CSI-RS transmission in WUS to receive CSI-RS.

In the seventh embodiment of the present application, on the basis of the fifth embodiment, offset4 is taken into consideration, where offset4 refers to the distance between WUS and OnDuration. This can be divided into the following situations.

In the first case, offset2<offset4 and offset3<offset4, the minimum triggering offset of the WUS to trigger the RS is the larger value of offset2 and offset3.

Exemplarily, as shown in FIG. 14A, offset2=1, offset3=2, and offset4=3. At this time, offset2<offset4 and offset3<offset4, the WUS trigger "minimum CSI-RS trigger offset value" is equal to offset3=2. For the terminal, since the terminal knows that the network device will definitely not trigger the transmission of CSI-RS before the second time slot after the time slot where the WUS DCI is located, the terminal can not buffer data during this time, thereby achieving the purpose of energy saving. After the terminal successfully decodes the WUS DCI, it can know the specific time slot where the CSI-RS triggered by the WUS is located, and then go to the actual time slot where the WUS triggers the CSI-RS to receive the CSI-RS.

In the second case, offset2>offset4 and offset3>offset4, the minimum triggering offset of the WUS to trigger the RS is offset4.

Exemplarily, as shown in FIG. 14B, offset2=5, offset3=4, offset4=3, at this time offset2>offset4 and offset3>offset4, then WUS triggers "minimum CSI-RS trigger offset value" equal to offset4, then WUS The triggered CSI-RS can be sent after the terminal enters On Duration. This can help the terminal to track the channel or perform operations such as beam management by receiving the CSI-RS triggered by the WUS more quickly, which helps to improve the performance. In addition, the terminal must have successfully decoded WUS before entering OnDuration, so after entering OnDuration, the terminal only needs to receive the CSI-RS in the actual time slot in which the WUS triggers RS transmission.

In the third case, if one of the offset2 and offset3 values is greater than offset4, and one is less than offset4, the WUS trigger "minimum CSI-RS trigger offset value" is equal to offset4.

Exemplarily, as shown in FIG. 14C, offset2=1, offset3=4, offset4=3, at this time offset2<offset4 and offset3>offset4, then WUS triggers the "minimum CSI-RS trigger offset value" of the aperiodic CSI-RS "Equal to offset4. When only considering offset2 and offset3, since the terminal knows that it will not receive the RS transmission triggered by WUS within offset2 and offset3, the terminal will select offset2 in order to further reduce the processing speed of decoding WUS and further save the power consumption of the terminal to detect WUS. The larger value of offset3 and offset3 is regarded as the minimum triggering offset, that is, the "minimum CSI-RS triggering offset value" is offset3. On this basis, considering offset4, at this time offset3>offset4, the WUS-triggered RS can be sent after the terminal enters OnDuration, that is, the "minimum CSI-RS trigger offset value" is equal to offset4. This can help the terminal to track the channel or perform operations such as beam management by receiving the RS triggered by the WUS more quickly, and contribute to the improvement of performance. In addition, the terminal must have successfully decoded WUS before entering OnDuration, so after entering OnDuration, the terminal only needs to receive the CSI-RS in the actual time slot in which the WUS triggers RS transmission.

It can be understood that, combining the above three situations, the "minimum CSI-RS trigger offset value" for WUS to trigger aperiodic CSI-RS can be determined by the following formula: min{max{offset2, offset3}, offset4}.
