Description

Reference signal resource transmission method, device and storage medium

technical field

The embodiments of the present application relate to communication technologies, and in particular, to a method, device, and storage medium for transmitting reference signal resources.

Background technique

The sounding reference signal (SRS) is an important uplink reference signal in the ^4th generation (4G) and ^5th generation (5G) mobile communication systems, which enables network equipment to obtain downlink channel status. Various functions such as information, antenna switching, uplink beam management and positioning.

At present, the 5G communication system supports flexible configuration of uplink and downlink resources, and the number of uplink symbols and downlink symbols contained in each time slot can be flexibly configured or indicated. However, in a time slot with fewer uplink symbols, the terminal device may not be able to completely transmit the SRS resources instructed by the network device to transmit in the time slot, resulting in the inability to implement the corresponding detection function. For example, the network device instructs the terminal device to send SRS resources on 4 consecutive symbols in a time slot, and to detect a larger channel bandwidth by frequency hopping on different symbols, however, when only 2 uplinks are included in the time slot symbol, the terminal equipment will not be able to completely transmit the SRS resources of 4 consecutive symbols in this time slot, and cannot complete the function of detecting a larger bandwidth. How to improve the reliability of reference signal transmission has become a problem to be solved at present.

The related technologies and terms involved in this application are described below.

1. Sounding reference signal SRS

The SRS signal is an important reference signal in the 5G new radio (NR) system and is widely used in various functions in the NR system, such as

1. For the acquisition of downlink channel state information (UE sounding procedure for DL CSI acquisition)

2. For uplink beam management

3. Used for positioning function

4. Cooperate with codebook-based uplink transmission (including frequency domain scheduling and determination of Rank/precoding matrix indicator (PMI)/Modulation Coding Scheme (MCS))

5. Cooperate with Non-Codebook based uplink transmission (including frequency domain scheduling and SRS resource indication (Sounding Reference Signal Resource Indicator, SRI)/MCS determination)

The network can configure one or more SRS resource groups (SRS Resource set) for a UE, and each SRS Resource set can configure one or more SRS resources (SRS resource).

The transmission of SRS can be divided into periodic (Periodic), semi-persistent (Semi-persistent), and aperiodic (Aperiodic). The details are as follows:

1. Periodic SRS and Semi-persistent SRS

Periodic SRS refers to periodically transmitted SRS, and its period and time slot offset are configured by radio resource control (RRC) signaling. Once the terminal receives the corresponding configuration parameters, it will send the SRS according to a certain period until The RRC configuration is invalid. The spatial correlation information (Spatial Relation Info, which indicates the transmission beam in an implicit manner) of the periodic SRS is also configured by RRC signaling. The spatial correlation information may indicate one CSI-RS, SSB or reference SRS, and the terminal determines the transmit beam of the third SRS resource according to the indicated receive beam of the CSI-RS/SSB, or determines the third SRS resource according to the transmit beam of the reference SRS resource. The transmit beam of the SRS resource.

Semi-persistent SRS is also a periodically transmitted SRS, and the period and slot offset are configured by RRC signaling, but its activation and deactivation signaling is through the medium access control control element (medium access control control element, MAC CE) is carried. The terminal starts to periodically transmit SRS after receiving the activation signaling until it receives the deactivation signaling. The spatially related information (transmission beam) of the semi-persistent SRS is carried along with the MAC CE that activates the SRS.

After receiving the period and time slot offset configured by RRC, the terminal determines the time slot that can be used to transmit SRS according to the following formula:

where T _SRS and T _offset are the configured period and offset, n _f and

are the radio frame and time slot numbers, respectively.

2. Aperiodic SRS transmission

In the NR system, aperiodic SRS transmission is introduced, and the base station can trigger the SRS transmission of the terminal through uplink or downlink DCI. The trigger signaling for triggering aperiodic SRS transmission can be carried either by the DCI used for scheduling PUSCH/PDSCH in the UE-specific search space, or by the DCI format 2_3 in the common search space. Among them, DCI format 2_3 can not only be used to trigger aperiodic SRS transmission, but also can be used to configure the TPC command of SRS on a group of UEs or a group of carriers at the same time. The corresponding relationship between the value of the SRS request field and the triggered SRS resource set may be as shown in Table 1.

Table 1

After receiving the aperiodic SRS trigger signaling (eg DCI), the terminal performs SRS transmission on the SRS resource set indicated by the trigger signaling. The time slot offset (slot offset) between the trigger signaling and the SRS transmission is configured by higher layer signaling (RRC). The network side instructs the terminal through high-layer signaling in advance the configuration parameters of each SRS resource set, including time-frequency resources, sequence parameters, power control parameters, and the like. In addition, for each SRS resource in the triggered SRS resource set, the terminal can also determine the transmission beam used for transmitting the SRS on the resource through the spatial correlation information of the resource, and the information is configured for each SRS resource through RRC.

Among them, for the slot offset (slot offset), if the UE receives the DCI signaling triggering the aperiodic SRS in the slot n, the UE will

Send the SRS resources in the corresponding set, as shown in Figure 1 below. Wherein, k is the RRC parameter slotOffset configured for each set, and μSRS and μPDCCH are the subcarrier spacing configurations of the triggering SRS and the PDCCH that carry the triggering command, respectively.

-SRS time domain resource configuration:

startPosition INTEGER(0..13),

The startPosition parameter is used to configure the symbol offset l _offset , that is, l _offset ∈ {0,1,...,13}.

nrofSymbols ENUMERATED{n1,n2,n4},

The nrofSymbols parameter is used to configure the number of consecutive OFDM symbols for SRS time domain resources

That is, each SRS resource can be configured in any symbol of a time slot, the time domain start symbol l ₀ of the SRS,

Count down ₁₀ symbols from the last symbol of the slot.

-SRS resource frequency domain configuration:

The frequency domain configuration of SRS is determined by the parameters C _SRS , B _SRS (configured by RRC signaling) in 3GPP protocol 38.211-Table 6.4.1.4.3-1 (as in Table 2), m _{SRS, b} are the physical resources for SRS transmission The number of physical resource blocks (PRBs), where b=B _SRS .

Table 2

The NR system supports frequency hopping of SRS. If b _hop <B _SRS is satisfied (where b _hop is an RRC configuration parameter), the terminal sends the SRS signal in the form of frequency hopping. Where m _SRS,0 is the total bandwidth of SRS frequency hopping, and m _SRS,b is the number of PRBs sent in each frequency hopping. And the terminal determines the frequency domain position of each frequency hopping by the following formula:

N _b is determined by 3GPP protocol 38.211-Table 6.4.1.4.3-1, n _RRC is the RRC configuration parameter, where F _b (n _SRS ) is determined by the following formula:

Among them, regardless of the value of the N _b parameter,

The parameter n _SRS represents the number of SRS frequency hopping. For aperiodic SRS, the number of SRS frequency hopping is determined by the following formula:

in,

is the number of consecutive OFDM symbols (configured for RRC), and is the repetition factor (configured by RRC) used to indicate the number of repeated OFDM symbols without frequency hopping. For example, when R=1, frequency hopping is performed in units of 1 OFDM symbol; when R=2, frequency hopping is performed in units of 2 OFDM symbols.

For periodic and half-period SRS, the number of SRS hopping is determined by the following formula:

Among them, T _SRS and T _offset are the configured period and offset, n _f and

are the radio frame and time slot numbers, respectively.

is the number of time slots contained in each frame.

2. Slot format indicator (SFI)

Or called slot format indication information, the slot format includes downlink symbols, uplink symbols and flexible symbols. The format of each slot of the UE is configured by the high layer parameter tdd-UL-DL-ConfigurationCommon. The tdd-UL-DL-ConfigurationCommon includes the subcarrier spacing configuration parameter referenceSubcarrierSpacing and the time slot format parameter pattern1. where pattern1 contains:

- Period P of slot configuration, configured by higher layer parameter dl-UL-TransmissionPeriodicity.

- The number of downlink time slots containing only downlink symbols, which is configured by the higher layer parameter nrofDownlinkSlots.

- The number of downlink symbols, which is configured by the high-level parameter nrofDownlinkSymbols.

- The number of uplink time slots containing only uplink symbols, which is configured by the higher layer parameter nrofUplinkSlots.

- The number of uplink symbols, which is configured by the high-level parameter nrofUplinkSymbols.

Further, if the UE is configured with a higher layer parameter SlotFormatIndicator, the UE can modify the slot format through DCI 2_0. The value of the SFI-index field in DCI2_0 indicates to the UE the slot format of each of the multiple time slots of each DL BWP or each UL BWP, and the effective position of the SFI is the first time when the UE detects DCI 2_0. Time slot starts. The SFI-index field contains the number of bits, and the value of maxSFIindex is the maximum value provided by the high-level parameter slotFormatCombinationId. The slot format is identified by the corresponding format index provided in Table 3, where 'D' represents downlink symbols, 'U' represents uplink symbols, and 'F' represents flexible symbols. It should be noted that the UE cannot indicate the symbols already configured as uplink symbols in tdd-UL-DL-ConfigurationCommon as downlink symbols through the SFI-index field in DCI2_0, and vice versa.

table 3

With the flexible configuration of uplink and downlink resources in the current 5G communication system, it may happen that the terminal equipment cannot fully transmit the reference signal resources in a certain time slot that needs to transmit the reference signal resources, which will cause the transmission delay of the reference signal, or The corresponding detection function cannot be effectively implemented because it cannot be completely transmitted. For example, it cannot effectively detect a large bandwidth, complete uplink beam management, and so on.

For example, the current NR system supports SRS frequency hopping, wherein the number of aperiodic SRS frequency hopping is also limited by the number of consecutive OFDM symbols configured by the network side for each SRS resource, thus limiting the channel bandwidth that can be detected.

At present, mobile phone terminals will support more and more transceiver antennas, such as 1T4R, 1T6R, 1T8R, 2T8R. According to the current protocol configuration, for the antenna switching scenario, whether it is periodic SRS, semi-periodic SRS or aperiodic SRS, it is impossible to completely transmit SRS resources in one time slot, and especially for aperiodic SRS, it is even necessary to configure multiple resource groups to Full transmission of aperiodic SRS resources is guaranteed.

The transmission of reference signal resources limited to one time slot will not meet the measurement or detection requirements of reference signal resources. A transmission mechanism is needed to support reference signal resources to be transmitted in multiple time slots and improve the robustness of reference signal resource transmission. . Therefore, it is proposed in this application that the network device can instruct the terminal device to transmit L reference signal resources in N time units, and the terminal device transmits at least one of the L reference signal resources in N time units according to the instruction of the network device. reference signal resources. This enables the terminal device to transmit the quantity of reference signal resources that meet the demand in time, and to complete functions such as measurement or detection of the reference signal resources in time. The probability of successful reference signal resource transmission is increased, and the reliability of reference signal resource transmission is improved.

The method for transmitting reference signal resources provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

FIG. 2 is a schematic flowchart of a method for transmitting reference signal resources provided by an embodiment of the present application.

S210: The network device determines first information, where the first information is used to instruct the terminal device to transmit L reference signal resources in N time units.

Among them, L and N are positive integers.

By way of example and not limitation, a time unit may be a slot, a subframe or a frame.

That is to say, the time units in the present application may all be replaced by time slots, or all may be replaced by subframes, or all may be replaced by frames. However, the present application is not limited thereto, and the time unit may also be other time units.

Optionally, the reference signal resource may be a demodulation reference signal (demodulation reference signal, DMRS) resource or a sounding reference signal (sounding reference signal, SRS) resource.

The network device may determine and instruct the terminal device to transmit one or more reference signal resources in one or more time units according to the usage requirements of the reference signal resources. For example, the reference signal resource is an SRS resource, and the network device may determine to instruct the terminal device to send an SRS resource for acquiring downlink channel state information within one time unit, that is, N=1, L=1, and the network device may generate the first SRS resource. information and send it to the terminal device. And, in order to fully measure the uplink beam for uplink beam management, the network device may determine to instruct the terminal device to transmit multiple SRS resources for performing uplink beam management in multiple time units. That is, N>1, L>1, it is possible to avoid the situation that the SRS resources cannot be completely transmitted due to resource conflict, and thus the uplink beam management cannot be completed. Alternatively, the network device may also determine and instruct the terminal device to repeatedly transmit one SRS resource in N time units according to other uses of the SRS resource. However, the present application is not limited to this. After determining that the terminal device needs to send L SRS resources in N time units, the network device generates first information, and sends the first information to the terminal device in S220 to notify the terminal device to send L SRS resources in N time units. SRS resources. However, the present application is not limited to this.

As an example and not limitation, the first information is a radio resource control (radio resource control, RRC) message, a medium access control control element (medium access control control element, MAC CE) or downlink control information (downlink control information, DCI).

Optionally, the first information includes configuration information of each reference signal resource in the L reference signal resources.

For example, the configuration information of the reference signal resource configures the starting position of the reference signal resource and the number of consecutive orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols. That is, each reference signal resource may occupy one or more OFDM symbols.

In an implementation manner, the starting position of the reference signal resource configured by the configuration information of the reference signal resource may be one of the sets {0, 1, 2, 3, 4, 5}, or the starting position may be is one of the set {0, 1, 2, 3...12, 13}.

In another implementation manner, the starting position of the reference signal resource configured by the configuration information of the reference signal resource may be a plurality of sets {0, 1, 2, 3, 4, 5}, or may be the starting position The positions can be multiple in the set {0, 1, 2, 3...12, 13}.

Optionally, the configuration information of the reference signal resource may indicate one or more values in the set of the number of consecutive OFDM symbols, indicating the number of consecutive OFDM symbols occupied by the reference signal resource.

For example, the reference signal resource configuration information can be written as SRS-Resource, the set of the number of consecutive OFDM symbols is {1, 2, 4}, and the configuration information of a reference signal resource in the first information indicates 2 in the set, It means that the reference signal resource occupies two consecutive OFDM symbols. However, the present application is not limited to this.

As an example and not limitation, the set of the number of consecutive OFDM symbols may be one or more of the following:

{1,2,4}, {1,2,4,8,12}, {1,2,4,8,12,14}, {1,2,4,8,12,16}, {1 ,2,4,8,12,18}, {1,2,4,8,12,28} or {14,16,18,28}.

Optionally, the set of consecutive OFDM symbols is {1, 2, 4};

Optionally, the set of consecutive OFDM symbols is {1, 2, 4, 8, 12};

Optionally, the set of consecutive OFDM symbols includes any one of {14, 16, 18, 28} and {1, 2, 4, 8, 12}, for example, the set is {1, 2, 4, 8, 12,14} or {1,2,4,8,12,16} or {1,2,4,8,12,18} or {1,2,4,8,12,28} etc., in SRS - The number of consecutive OFDM symbols configured in the Resource is one of the above sets;

Optionally, the set of the number of consecutive OFDM symbols is any two of {14, 16, 18, 28} and {1, 2, 4, 8, 12}, and the number of consecutive OFDM symbols is configured in the SRS-Resource is a value in the above set;

Optionally, the set of the number of consecutive OFDM symbols is any three of {14, 16, 18, 28} and {1, 2, 4, 8, 12}, and the number of consecutive OFDM symbols is configured in the SRS-Resource is a value in the above set;

Optionally, the set of the number of consecutive OFDM symbols is {1, 2, 4, 8, 12, 14, 16, 18, 28}, and the number of consecutive OFDM symbols configured in the SRS-Resource is one of the above sets. value.

According to the above solution, more consecutive OFDM symbol configurations can be supported, and a larger channel bandwidth can be detected in a frequency hopping scenario. In addition, the transmission of SRS resources across time slots is supported, so as to avoid the failure of SRS transmission, and the transmission of SRS resources can be postponed to the next time slot for joint transmission.

The reference signal resource configuration information (for example, SRS-Resource) may also configure a repetition factor of the reference signal resources, where the repetition factor is the repetition times of the reference signal resources in a time unit (for example, a time slot, subframe or frame) .

Optionally, the set of repetition factors is {1,2,4};

Optionally, the set of repetition factors is {1, 2, 4, 8, 12};

Optionally, the set of repetition factors includes any one of {14, 16, 18, 28} and {1, 2, 4, 8, 12}, for example, the set is {1, 2, 4, 8, 12, 14 } or {1,2,4,8,12,16} or {1,2,4,8,12,18} or {1,2,4,8,12,28} etc, in SRS-Resource Configure the number of consecutive OFDM symbols to be one of the above sets;

Optionally, the set of repetition factors includes any two of {14, 16, 18, 28} and {1, 2, 4, 8, 12}, and the number of consecutive OFDM symbols configured in the SRS-Resource is the above set one of the values;

Optionally, the set of repetition factors includes any three of {14, 16, 18, 28} and {1, 2, 4, 8, 12}, and the number of consecutive OFDM symbols configured in the SRS-Resource is the above set one of the values;

Optionally, the set of repetition factors includes {1, 2, 4, 8, 12, 14, 16, 18, 28}, and the number of consecutive OFDM symbols configured in the SRS-Resource is one of the above sets.

Optionally, the L reference signal resources are pre-configured by the network device for the terminal device through configuration information, and the first information may include identification information of each reference signal resource in the L reference signal resources.

For example, before sending the first information, the network device sends an RRC message to the terminal device, where the RRC message includes configuration information of the L reference signal resources, and the first information may include identification information of the L reference signal resources. Or, the RRC message includes configuration information of a first set, where the first set includes the L reference signal resources, and the first information may include identification information of the first set. But the application is not limited to this.

Optionally, the first information is configuration information of a first set, and the first information further includes usage configuration parameters of the first set.

For example, the first set is an SRS resource set, and the usage of the SRS resource set can be configured as one of beam management (beamManagement), codebook (codebook), non-codebook (nonCodebook) and antenna switching (antennaSwitching). That is to say, the first information may select a usage from the usage set {beamManagement, codebook, nonCodebook, antennaSwitching} as the usage of the SRS resource set. However, the present application is not limited to this.

The configuration information of the reference signal resource can configure the frequency domain related parameters for the reference signal. For example, the configuration information of the SRS (for example, written as SRS-Resource) can configure the frequency domain related parameters of the SRS, and the c-SRS can be configured as one of 0 to 63 , b-SRS can be configured as one of 0 to 3, and b-hop can be configured as one of 0 to 3. However, the present application is not limited to this.

In addition, the first information may indicate the number N of time units included in the N time units in the following manner.

In an embodiment, the first information includes second indication information, where the second indication information is used to indicate the number N of time units included in the N time units.

For example, the second indication information in the first information indicates 3, indicating that the number of time units included in the N time units is 3, that is, the first information indicates that L reference signal resources are transmitted in 3 time units . However, the present application is not limited to this.

In another implementation manner, the first information includes fourth indication information, and the fourth indication information includes a bit string of P bits, where the P bits correspond to the P time units, wherein among the P bits N bits indicate the first value, the N time units are time units corresponding to the N bits, P is a positive integer, and P≧N.

Optionally, the length P of the bit string may be specified by the protocol or configured by higher layer parameters.

That is to say, the number of bits indicating the first value among the P bits is N.

For example, the fourth indication information in the first information includes a bit string of 8 bits (ie, P=8), and the bit string may also be called a bitmap or a bitmap (bitmap). When four bits in the bit string are set to "1", the N time units are the four time units corresponding to the four bits set to "1". If the bit string is 00110110, it means that the 3rd, 4th, 6th, and 7th time units in the 8 time units corresponding to the bit string are used for transmitting the L reference signal resources. However, the present application is not limited to this.

S220, the network device sends the first information to the terminal device.

Accordingly, the terminal device receives the first information from the network device.

Optionally, the terminal device may report capability information to the network device before receiving the first information, where the capability information is used to indicate that the terminal device supports sending one or more reference signal resources in multiple time slots, or in other words, the capability information Used to indicate that the terminal device supports the transmission of one or more reference signal resources across time slots.

S230: The terminal device determines, according to the first information, to transmit at least one reference signal resource among the L reference signal resources in each of the N time units.

First, the terminal device may determine the positions of the N time units according to the first information, that is, the positions of the time units in which the L reference signal resources are transmitted. When the time unit is a slot, it may be called a slot position; when the time unit is a subframe, it may be called a subframe position; or when the time unit is a frame, it may be called a frame position. However, the present application is not limited to this.

In an embodiment, the protocol specifies a first time offset, where the first time offset is the number R of time units by which the N time units are offset with respect to the reference time unit.

Optionally, the definition of the number R of time units offset by the reference time unit may be the Rth physical time unit (for example, the physical time unit may be a physical time slot), or the R+1th physical time unit ( That is, the value of R contains 0).

Optionally, the definition of the number R of time units offset by the reference time unit may be the Rth effective time unit, or the R+1th effective time unit (the value of R includes 0).

In this application, the reference time unit may be referred to as a reference time slot if the time unit is a time slot, or may be referred to as a reference subframe if the time unit is a subframe, or may be referred to as a reference subframe if the time unit is a subframe. In the case of a frame, the reference time unit may be referred to as a reference frame. However, the present application is not limited thereto, and the time unit may also be other time units.

In an example, the first information is carried in a first time unit, and the second indication information included in the first information indicates the number N of time units included in the N time units, then the first time offset is the number of time units offset by the N time units with the first time unit as the reference time unit, for example, if the first time offset is M, then the Mth time unit after the first time unit is the first time unit in the N time units.

For example, the protocol specifies that the time unit offset of N time units is 3. As shown in FIG. 3 , the network device sends the first information in time unit n (ie, an example of the first time unit), and the first information indicates that L reference signal resources are transmitted in 4 time units. Then the 4 time units are the third time unit after time unit n is the 4 time units of the starting time unit, namely time unit n+3, n+4, n+5 and time unit n+6, but The present application is not limited to this.

In another example, the network device sends the second information to the terminal device in the second time unit, where the second information is used to trigger the terminal device to transmit the L reference signal resources. The first time offset may be the number of time units offset by the N time units taking the second time unit as a reference time unit. For example, if the first time offset is M, the Mth time unit after the second time unit is the first time unit in the N time units.

For example, the first information may be an RRC message, and the network device configures L reference signal resources through the RRC message, and the L reference signal resources are transmitted in N time units. The network device sends the second information to the terminal device in the second time unit, triggering the terminal device to transmit the L reference signal resources in the N time units. Then the first time unit of the N time units is the Mth time unit after the second time unit. However, the present application is not limited to this.

In another example, the first information is carried in a first time unit, and the first information includes fourth indication information, that is, a bit string including P bits, wherein the P bits correspond to P time units, and the The first time offset may be the number of time units by which the first time unit of the P time units is offset when the first time unit is used as the reference time unit. For example, if the first time offset is Q, the Qth time unit after the first time unit is the first time unit in the P time units.

For example, as shown in FIG. 4 , the network device sends the first information in time unit n (ie, an example of the first time unit), the first information includes fourth indication information, and the fourth indication information includes 5 bits of bits string (ie P=5), the bit string is 00110. If the first time offset is 3, the first time unit of the 5 time units corresponding to the 5 bits is the third time unit after time unit n, that is, time unit n+3. Then the five time units are time unit n+3 to time unit n+7. Among them, the third bit and the fourth bit in the 5 bits, two bits indicate the first value, that is, indicate "1", then the number of time units included in the N time units is 2, and the 2 time units The time units are respectively the time unit n+5 corresponding to the third bit and the time unit n+6 corresponding to the fourth bit. However, the present application is not limited to this.

In another example, the first information includes fourth indication information, and the network device triggers the terminal device to transmit the L reference signal resources by sending the second information to the terminal device in the second time unit. Then, the first time offset may be the number of time units by which the first time unit of the P time units is offset when the second time unit is used as the reference time unit. For example, if the first time offset is Q, the Qth time unit after the second time unit is the first time unit in the P time units.

In another implementation manner, the first information includes third indication information, and the third indication information is used for the second time unit offset.

The second time offset may be the number of time units offset by the N time units or the P time units corresponding to the P bits using the first time unit as a reference time unit, or the second time offset It may be the number of time units offset by the N time units or the P time units corresponding to the P bits using the second time unit as a reference time unit. However, the present application is not limited to this. For specific embodiments, reference may be made to the description in the previous embodiment, which is not repeated here for brevity.

In another embodiment, the time offset of the N time units may be indicated by one or more of RRC message, MAC CE or DCI.

For example, the priority order indicated by the RRC message, the MAC CE and the DCI can be specified, and the terminal device determines the time offset of the N time units according to the received information with the highest priority. For example, it may be specified that the indicated priority order is DCI>MAC CE>RRC. The time slot offset configured by the RRC message is 0, the time unit offset indicated by the network device through the MAC CE is A, and the terminal device is triggered to send the L reference signal resources, then the terminal device determines that the N time units and the The time offset between the time units where the MAC CE is located is A. If the time offset configured by the network device through the RRC message is 0, and the time offset indicated by the MAC CE is A, and the time offset indicated by the DCI is B, and the DCI is used to trigger the terminal device to send the L With reference to the signal resource, the terminal device may determine that the time offset between the N time units and the time unit where the DCI is located is B. However, the present application is not limited to this.

For another example, the terminal device jointly determines the time unit offsets of the N time units according to the received indication information indicating the time unit offsets. For example, the network device configures the time offset as 1 through the RRC message, the network device triggers the terminal device to send the L reference signal resources through the MAC CE, and the MAC CE indicates that the time offset is A, then the N time units The offset relative to the reference time unit is 1+A. Or, the network device configures the time offset as 1 through the RRC message, the network device triggers the terminal device to send the L reference signal resources through DCI, and the DCI indicates that the time offset is B, then the N time units are relative to The offset of the reference time unit is 1+B. Or, if the network device indicates that the time offset is A through the MAC CE, and triggers the terminal device to send the L reference signal resources through DCI, and the DCI indicates that the time offset is B, then the N time units are relative to the reference time The offset of the cell is A+B. However, the present application is not limited to this.

It should be noted that the number of offset time units of the first time unit in the N time units relative to the reference time unit may be 0, that is, the first time unit of the N time units is the reference time unit . The time offset may also be 1, that is, the first time unit of the N time units is the next time unit of the reference time unit. That is to say, the number of offset time units of the first time unit in the N time units relative to the reference time unit may be a value greater than or equal to 0.

In this application, the transmission manner of the L reference signal resources in the N time units may include one or more of the following implementation manners.

Embodiment 1, L=1, the first information specifically instructs the terminal device to transmit one reference signal resource in N time units.

For example, the network device may configure reference signal resource A for the terminal device, the starting symbol of reference signal resource A is the fourth last OFDM symbol in a time unit, and the reference signal resource A occupies 8 consecutive OFDM symbols. The first information includes fourth indication information, and the bit string containing 4 bits in the fourth indication information is 1100. For example, as shown in FIG. 5, the reference time unit is time unit n, and the time offset is M, then the first time unit of the 4 time units corresponding to the 4-bit bit string is time unit n+M. If the first 2 bits in the string are set to "1", the N time units include 2 time units, namely time unit n+M and time unit n+M+1. Because the reference signal resource A is configured to occupy 8 consecutive OFDM symbols with the fourth last OFDM symbol as the starting symbol (that is, the symbol position of the reference signal resource A is 8 consecutive OFDM symbols where the fourth OFDM symbol is the starting symbol) OFDM symbols), therefore, the reference signal resource A occupies OFDM symbol 10 to OFDM symbol 13 in time unit n+M and occupies OFDM symbol 0 to OFDM symbol 3 in time unit n+M+1. However, the present application is not limited to this.

It should be noted that, in the examples of this application, the time unit may be replaced by the time unit in the specific implementation according to the specific implementation, and the reference signal resource may be replaced by the reference signal resource in the specific implementation. The unit is a time slot, and the reference signal resource A is an SRS resource A, then the symbol position of the SRS resource A is the OFDM symbol 10 to OFDM symbol 13 in the time slot n+M, and the OFDM symbol in the time slot n+M+1. 0 to OFDM symbol 3, other examples can also be similarly replaced, and for brevity, the details are not repeated.

For another example, the bit string of 6 bits in the fourth indication information is 110110. As shown in FIG. 6 , the reference time unit is time unit n, and the time offset is M, then the 6 bits corresponding to the 6-bit bit string are The first time unit of the time units is time unit n+M. Since the 1st, 2nd, 4th, and 5th bits in the bit string are set to "1", the N time units include 2 time units, namely the time unit n+M, n+M+1, n+M+3, n+M+4. Since the reference signal resource A is configured to occupy 8 consecutive OFDM symbols with the fourth last OFDM symbol as the starting symbol, the reference signal resource A occupies OFDM symbols 10 to 13 in the time unit n+M and time OFDM symbol 0 to OFDM symbol 3 in unit n+M+1 and the reference signal resource A are repeatedly transmitted once in time units n+M+3 and n+M+4, but the present application is not limited thereto.

The first information may be an RRC message, and the first information may be configuration information of reference signal resources. For example, the reference signal resources may be SRS resources, and the first information may be written as SRS-Resource. The fourth indication information may be called a cross-slot bitmap, which may be written as crossSlotbitmap, and the fourth indication information includes a bit string of length P. The fourth indication information may be an optional (OPTIONAL) configuration item in the first information. For example, the first information may be as follows:

Wherein, the SRS-Resource may further include the identification information of the SRS resource, the srs-ResourceId, and the configuration information nrofSRS-Ports of the number of antenna ports of the SRS resource, but the present application is not limited to this. The first information may also include other unlisted information.

For another example, the first information includes the second indication information indicating the number N of N time units. The first information may be an RRC message, and the first information may be configuration information of reference signal resources. For example, the reference signal resources may be SRS resources, and the first information may be written as SRS-Resource. The second indication information may be referred to as a cross-slot size, which may be written as crossSlotSize, and the crossSlotSize may indicate an integer value from 0 to Y, for example, indicates N, where N≤Y. The second indication information may be an optional (OPTIONAL) configuration item in the first information. For example, the first information may be as follows:

Optionally, the first information includes the second indication information indicating the number N of N time units, where the N time units are consecutive N time units; or, the N time units are consecutively available time units; the The N time units are time units that include uplink symbols and/or flexible symbols; or, the N time units are time units that include OFDM symbols used for transmitting the L reference signal resources; or, The N time units are time units including orthogonal frequency division multiple access OFDM symbols used for transmitting part or all of the L reference signal resources.

The N time units determined by the terminal device according to the above definition of the N time units may be referred to as valid time units of the N time units. When the time unit is a time slot, the effective time unit can be called an effective time slot; when the time unit is a subframe, the effective time unit can be called an effective subframe; when the time unit is a frame , the valid time unit may be referred to as a valid frame. However, the present application is not limited to this.

For example, the N time units are consecutive N time units, if the reference time unit is time unit n and the time offset is M, then the starting unit of the N time units is time unit n+M, and the The N time units include time unit n+M to time unit n+M+N-1. However, the present application is not limited to this.

For another example, the network device pre-indicates the uplink and downlink formats of the time resources to the terminal device, wherein each time unit may include uplink symbols, downlink symbols and flexible symbols. The N time units may be N time units including uplink symbols (ie, OFDM symbols used to transmit uplink signals or channels). If the reference time unit is time unit n, and the time offset is M, if time unit n+M contains uplink symbols, the starting time unit of the N time units is the time unit n+M, if time unit n+M Does not include uplink symbols, then the first time unit after time unit n+M that includes uplink symbols is the starting time unit of N time units, and sequentially determines the N time units that include uplink symbols after time unit n+M, namely is the time unit for transmitting the L reference signal resources. However, the present application is not limited to this. Alternatively, the N time units may be time units containing uplink symbols and/or flexible symbols, that is, time unit n+M is the N time units containing uplink symbols and/or flexible symbols in the time unit of the starting time unit The time unit is a time unit for transmitting L reference signal resources.

For another example, the terminal device determines, according to the priority of the resources, a time unit that can be used to send the reference signal resource in the time unit starting from time unit n+M, for example, the time unit that needs to be occupied by the reference signal resource in time unit n+M. The symbol is an uplink symbol, and there is no signal or channel with a higher priority than the reference signal resource that needs to be transmitted on the uplink symbol, then it can be determined that the time unit n+M includes the OFDM symbol used for transmitting the reference signal resource. The unit n+M is the first time unit in the N time units, and it is determined that N-1 time units after the time unit n+M include the OFDM symbols used for transmitting the reference signal resource.

Alternatively, the N time units may be a time unit in which time unit n+M is a start time unit and includes at least one OFDM symbol for transmitting the reference signal resource. For example, if at least one of the symbols to be occupied by the reference signal resource in the time unit n+M is an uplink symbol, and no signal or channel with a higher priority than the reference signal needs to be transmitted on the at least one symbol, then the time Unit n+M is the starting time unit of the N time units. For example, the reference signal resource needs to occupy the last two symbols in the time unit. If at least one of the last two symbols in the time unit n+M can be used to transmit the reference signal resource, the time unit n+M is the The starting time unit of the N time units, and then determine that the time unit after the time unit n+M includes a time unit that can be used to transmit at least one symbol of the reference signal resource (that is, it includes the time unit used to transmit the reference signal resource. time unit of an OFDM symbol for some or all of the resources). That is to say, even if some OFDM symbols are used to transmit reference signal resources, they are considered as valid time units, so that reference signal resources can be sent as soon as possible to the maximum extent, the timeliness of sending reference signal resources can be improved, and the system performance can be improved.

Wherein, the signal or channel with a higher priority than the reference signal resource may include a physical uplink control channel (PUCCH) or a channel ( physical uplink shared channel, PUSCH), etc., but this application does not limit it.

For example, the N time units are N time units including orthogonal frequency division multiple access OFDM symbols used for transmitting part or all of the reference signal resource A. The reference signal resource A occupies the last 4 OFDM symbols in a time unit, and the second indication information in the first information indicates N=3. For example, as shown in FIG. 7, the network device pre-configures the uplink and downlink symbol formats for the terminal device, and 3 symbols out of the 4 OFDM symbols that the reference signal resource A needs to occupy in the time unit n+M are uplink symbols, then the time unit n +M is the first time unit in the N time units, and the time unit n+M+1 does not include uplink symbols, then the time unit is not used as a time unit in the N time units, and then the time unit n+ In M+2 and n+M+3, the last 4 OFDM symbols to be occupied by reference signal resource A are uplink symbols and are not occupied by signals or channels of higher priority, so the 3 OFDM symbols used to transmit the reference signal resource A The time units are time units n+M, n+M+2, and n+M+3. However, the present application is not limited to this.

Example 2, L>1, the first information specifically instructs the terminal device to transmit the L reference signal resources once in each of the N time units.

That is to say, the L reference signal resources include multiple reference signal resources, and the L reference signal resources are repeatedly transmitted in N time units.

Optionally, the L reference signal resources may be reference signal resources in the first set, and the first information may be configuration information of the first set. For example, the reference signal resource is an SRS resource, and the first information may be configuration information of an SRS resource set, which may be written as SRS-ResourceSet. When the first information includes second indication information, the second indication information may be written as crossSlotSize, which is used to indicate the number N of time units for transmitting L reference signal resources. The crossSlotSize may indicate an integer value from 0 to Y, eg, indicates N, where N≤Y. The SRS-ResourceSet can be as follows:

The identification information srs-ResourceSetId of the first set is also configured in the SRS-ResourceSet, and the L SRS resources included in the first set can be configured through srs-ResourceIdList. However, the present application is not limited to this, and the SRS-ResourceSet may also include other configuration information.

Optionally, the first information includes the second indication information indicating the number N of N time units. The N time units are consecutive N time units, or, the N time units are N time units including uplink symbols and/or flexible symbols; N time units of OFDM symbols of the reference signal resources; or, the N time units are OFDMs that include a part or all of the resources for transmitting the L reference signal resources N time units of the symbol.

For the specific implementation of determining the N time units, reference may be made to Example 1, which is not repeated here for brevity.

When the first information includes fourth indication information, the fourth indication information may be referred to as a cross-slot bitmap, which may be written as crossSlotbitmap, and the fourth indication information includes a bit string of length P. The fourth indication information may be an optional (OPTIONAL) configuration item in the first information. The SRS-ResourceSet can be as follows:

SRS-ResourceSet can be as follows:

For example, as shown in FIG. 8 , L=2, N=3, L reference signal resources include 2 reference signal resources, wherein one reference signal resource occupies

OFDM symbols

9 and 10 in one time unit, and the other reference signal resource occupies

OFDM symbols

9 and 10 in one time unit. Occupies

OFDM symbols

12, 13 in one time unit. The three time units used for transmitting the L reference signal resources are three consecutive time units. Then the three time units are time units n+M, n+M+1, and n+M+2. However, the present application is not limited to this.

Example 3, L>1, the first information specifically instructs the terminal device to transmit at least one reference signal resource among the L reference signal resources in each of the N time units, and each of the N time units The number of reference signal resources in the L reference signal resources transmitted in the time unit is less than L.

In one implementation, for example, the reference signal resources are SRS resources, the L reference signal resources are reference signal resources in the SRS resource set, and the usage (usage) of the SRS-ResourceSet can be configured as antenna switching (for example, for 1T6R, 1T8R, 2T8R, etc.), that is, different SRS resources in the SRS resource set can be transmitted on different transmit antennas. Alternatively, the usage (usage) of the SRS-ResourceSet may also be configured as other usages such as {beamManagement, codebook, nonCodebook, antennaSwitching}.

That is, the L reference signal resources are distributed and transmitted in N time units.

Wherein, the first information may include the second indication information or the fourth indication information, and the specific implementation may refer to the description in the second example. The terminal device may determine the number of time units included in the N time units according to the second indication information or the fourth indication information, and the terminal device may also determine the number N of time units according to one of the following embodiments.

In one embodiment, the terminal device determines the number N of time units included in the N time units according to the number of time units occupied by each of the L reference signal resources, wherein,

n _l is the number of time units occupied by the lth reference signal resource in the L reference signal resources.

For example, the first information indicates to transmit L reference signal resources in the first set, L=3, where the number of time units occupied by the first reference signal is 2, the second reference signal resource and the third reference signal The number of occupied time units is all 1, then N=2+1+1=4. Then the terminal equipment can determine to transmit the 3 reference signal resources in 4 time units. However, the present application is not limited to this.

In another embodiment, the terminal device determines the number N of time units included in the N time units according to the number L of reference signal resources included in the L reference signal resources and the first mapping relationship, wherein, The first mapping relationship is a mapping relationship between the number of reference signal resources and the number of time units.

For example, the first mapping relationship may be as shown in Table 4. For example, the L reference signal resources include one reference signal resource, and N=1, that is, the one reference signal resource indicated by the first information is transmitted in one time unit. If L=8, then N=3, that is, the 8 reference signal resources indicated by the first information are transmitted in 3 time units. However, the present application is not limited to this.

In another embodiment, the protocol may specify at least one threshold value for the number of reference signal resources. When the number of reference signal resources is less than the threshold value, the number of time units is N1, and the number of reference signal resources is greater than the threshold value. When , the number of time units is N2.

For example, the threshold value of the number of reference signal resources is 4, and when the number of reference signal resources in the L reference signal resources is L≤4, the number of time units is N=1; When the number of reference signal resources L>4, the number of time unit units is 2. However, the present application is not limited to this.

The terminal device may determine the time unit occupied by each reference signal resource in the following manner.

In an embodiment, the terminal device determines, according to the number L of reference signal resources included in the L reference signal resources, to transmit the reference signal in the L reference signal resources in each time unit of the N time units. The number of signal resources, wherein the first N-1 time units in the N time units transmit the signal resources of the L reference signal resources

reference signal resources, and the Nth time unit among the N time units is used to transmit the reference signal resources among the L reference signal resources.

reference signal resources.

That is to say, if the number of reference signal resources cannot be divisible by the number of time units N, more reference signal resources may be sent in the earlier time unit, and fewer reference signal resources may be sent in the later time unit, Thus, the delay of reference signal resource transmission is reduced. For example, if the SRS resource set includes 3 SRS resources and occupies 2 time slots, two SRS resources with smaller identifiers (identifiers, IDs) may be sent in the first time slot, and the largest IDs may be sent in the second time slot SRS resources. However, the present application is not limited to this.

For example, if the first information indicates that 7 reference signal resources are to be transmitted in 4 time units, the terminal device may determine to transmit 2 of the 7 reference signal resources in the first 3 time units of the 4 time units, respectively. For reference signal resources, one reference signal resource is transmitted in the last time unit of the four time units. Optionally, in the N time units, the L reference signal resources are sequentially transmitted in the order of the L first identifiers from small to large or from large to small, wherein one of the second identifiers is used to identify One reference signal resource of the L reference signal resources.

Optionally, when configuring the L reference signal resources for the terminal device, the network device may configure a first identifier for each reference signal resource, and the values of the L second identifiers are different in size. In the N time units, the L reference signal resources are sequentially transmitted in an ascending order of the L second identifiers or a descending order.

Optionally, the order in which the L reference signals are transmitted may be specified by a protocol or may be indicated by a network device.

In another implementation manner, the first information includes first indication information, where the first indication information is used to indicate a time unit respectively occupied by each of the L reference signal resources in the N time units.

In an embodiment, the first indication information includes L first identifiers, the L first identifiers correspond to the L reference signal resources, and one first identifier is used to indicate the corresponding The time unit occupied by the reference signal resource in the N time units.

In other words, the first indication information includes an identifier in the N time units of a time unit occupied by each of the L reference signal resources. For example, the first information indicates that five reference signal resources (such as reference signal resources A, B, C, D, and E) in the first set are transmitted in three time units, and the identifiers of the three time units (that is, the first Identification) information is 1, 2, 3 respectively, the first indication information in the first information includes five first identifications, the five first identifications are 1, 1, 2, 3, 3, the five first identifications Corresponding to the 5 reference signal resources in sequence, therefore, the terminal device can determine, according to the first indication information, that the reference signal resources A and B in the 5 reference signal resources occupy a time unit with an identifier of 1, a reference signal resource A, and a reference signal resource B. The signal resource C occupies the time unit whose time unit identifier is 2, and the reference signal resources D and E occupy the time unit whose time unit identifier information is 3, but the present application is not limited to this.

In another implementation manner, the first indication information includes L first values, the L first values correspond to the L reference signal resources, and one of the first values corresponds to the The number of time units of the interval between the time unit occupied by the reference signal resource and the first time unit of the N time units.

In other words, the first indication information includes the number of time units spaced between the time unit occupied by each of the L reference signal resources and the first time unit of the N time units.

For example, the first information indicates that 5 reference signal resources (such as reference signal resources A, B, C, D, and E) in the first set are transmitted in 3 time units, and the first indication information includes 5 first values, The five first values are 0, 0, 1, 2, and 2 respectively, and the five first values correspond to the five reference signal resources in sequence. Therefore, the terminal device can determine the reference signal resources according to the first indication information A and B are separated from the first time unit of the three time units by 0 time units, indicating that the reference signal resources A and B are transmitted in the first time unit of the three time units; the reference signal resource C and the The first time unit in the three time units is separated by one time unit, indicating that the reference signal resource C is transmitted in the second time unit of the three time units; the reference signal resources D and E are related to the three time units. The first time unit in the unit is separated by two time units, indicating that the reference signal resources D and E are transmitted in the third time unit among the three time units, but the present application is not limited to this.

After receiving the first information, the terminal device may determine, according to the first information, the L reference signal resources indicated by the network device and the N time units indicated by the network device for transmitting the L reference signal resources. However, whether the L reference signal resources can be transmitted also needs to determine K time units in the N time units that can transmit resources in the L reference signal resources according to the priority of the resources in actual communication in S230.

S240: The terminal device determines, according to the priorities of the resources in the N time units, to transmit at least one reference signal resource among the L reference signal resources in K time units of the N time units.

For example, as shown in FIG. 9 , the first information indicates that one reference signal resource (for example, reference signal resource A) is transmitted in three consecutive time units, and the reference signal resource A occupies

symbols

10, 11, 12, and 13 in each time unit. There are 4 symbols in total, and the 3 time units are time units n+M, n+M+1, and n+M+2. However, according to the uplink and downlink formats configured by the network equipment, the

symbols

10 and 11 in the time unit n+M are not uplink symbols, so the reference signal resources and

symbols

10, 11, 12, and 13 in the time unit n+M+1 cannot be transmitted. Both are downlink symbols, therefore, the reference signal resource A cannot be transmitted in this time unit. Therefore, the terminal device can determine the resources in the 2 transmission reference signal resource A in the 3 time units, that is to say, transmit some resources of the reference signal resource A in symbols 13 and 14 in the time unit n+M, All resources of reference signal resource A are transmitted in time unit n+M+2. However, the present application is not limited to this.

For another example, the first information indicates that 2 reference signal resources in the first set, reference signal resource A and reference signal resource B, are transmitted once in each of the N time units, and the reference signal resources in the N time units are transmitted once. If a time unit does not contain uplink symbols, the terminal device does not transmit the two reference signal resources in the first set in this time unit. The other time units in the N time units may be used for transmitting the resources in the reference signal resource A. Then, the terminal device determines to transmit the resources among the L reference signal resources in N-1 time units (ie, K=N-1) among the N time units.

For another example, the first information indicates that 2 reference signal resources in the first set, reference signal resource A and reference signal resource B, are transmitted once in each of the N time units, and the reference signal resources in the N time units are transmitted once. The 2 symbols occupied by the reference signal resource A in one time unit need to transmit the PUCCH, that is, the reference signal resource A and the PUCCH resource overlap. The PUCCH is transmitted on the 2 symbols in the unit, and the reference signal resource A is not transmitted in this time unit, and only the reference signal resource B is transmitted. The other time units in the N time units may be used for transmitting the two reference signal resources in the first set. Then the terminal device determines to transmit the resources in the 2 reference signal resources in the N time units, wherein only the reference signal resource B is transmitted in one time unit, and the 2 reference signals in the first set are transmitted once in other time units. resource. However, the present application is not limited to this.

S250, the terminal device sends at least one reference signal resource among the L reference signal resources to the network device in the K time units.

After the terminal device determines in S240 K time units in the N time units that can actually transmit at least one reference signal resource among the L reference signal resources, the terminal device sends the L reference signal resources to the network device in the K time units. At least one reference signal resource in the signal resources.

Correspondingly, the network device receives at least one reference signal resource in the L time units from the terminal device in the K time units.

According to the above solution, the terminal device can transmit at least one reference signal resource among the L reference signal resources in N time units according to the instruction of the network device. This enables the terminal device to transmit the quantity of reference signal resources that meet the demand in time, and to complete functions such as measurement or detection of the reference signal resources in time. The reliability of reference signal resource transmission is improved. It is possible to configure a reference signal resource set for terminal devices with different capabilities, support the transmission of reference signal resources in a cross-slot mode, ensure timeliness, reduce signaling overhead and improve the probability of successful transmission of reference signal resources. The network can flexibly trigger the transmission of reference signal resources through the method provided in this application, and flexibly control the complexity of scheduling and implementation.

Based on the above solution, when the reference signal resource is an SRS resource, the network can configure multiple SRS flexible triggering modes for the terminal. For example, the transmission of SRS resources across time slots can support more continuous OFDM symbol configurations, support triggering multiple SRS resources in one time slot, support detection of larger channel bandwidth in frequency hopping scenarios, and make rational use flexible The convenience of time slots. It can also increase the successful transmission of SRS, and meet the requirement of triggering a large number of SRS resources under special circumstances. Cross-slot transmission of aperiodic SRS resource sets with antenna switching, which can configure an aperiodic SRS resource set for UEs with different capabilities and support the transmission of all SRS resources in a cross-slot mode, ensuring timeliness while reducing signaling overhead and improving SRS Successful transfer of the resource. The network can flexibly trigger the transmission of the SRS through the present application, and flexibly control the complexity of scheduling and implementation.
