Example 1

FIG. 2 is a flowchart of a data interrupt indication method according to the first embodiment, which is applied to a terminal device side. As shown in Figure 2, the method includes:

Step 201: The terminal device receives first indication information of a third time-frequency resource sent by the network device and used to instruct the terminal device to send uplink data.

Step 202: The terminal device detects interruption indication information sent by the network device within the detection time, and the interruption indication information is used to indicate a first time-frequency resource that interrupts data transmission.

In this embodiment, when the terminal device has uplink data transmission, the resource of the terminal device sending the uplink data may be occupied by a terminal device with a higher priority than the terminal device to send the uplink data of the high-priority terminal device. If the terminal device still sends uplink data on the resource, it will cause interference to the uplink data transmission of the high-priority terminal device. Therefore, in this embodiment, the terminal device detects the interruption indication information sent by the network device at the detection time. To determine whether the uplink data transmission needs to be interrupted. As a result, it is possible to ensure that the low-priority terminal equipment low-power detection interrupt indication information interrupts the uplink data transmission, effectively avoids mutual interference, and ensures the reliability or delay requirements of the uplink data transmission of the high-priority terminal equipment. Resource utilization.

In this embodiment, the method may further include: (optional)

Step 203: The terminal device sends the uplink data to the network device on a second time-frequency resource. The second time-frequency resource does not include the first time-frequency resource. Or, the terminal device is not on the first time-frequency resource. Sending the uplink data, or the terminal device stops sending the uplink data.

In step 201, the first indication information may be high-level configuration information configured by the network device to configure semi-static uplink transmission resources, or may be resource allocation information carried in uplink scheduling authorization control information, which is not described herein again. Optionally, before step 201, the method may further include (not shown): the terminal device sends uplink scheduling request information to the network device, and the terminal device notifies the network device of the uplink data to be sent through the uplink scheduling request information, Request network equipment to allocate uplink data transmission resources. The high-level configuration information, uplink scheduling control authorization control information, and uplink scheduling request information of the semi-static uplink transmission resources are specific to the prior art, and are not repeated here.

In this embodiment, in step 202, in order to determine whether the uplink data transmission needs to be interrupted, the terminal device needs to detect the interruption indication information sent by the network device at a detection time, and the detection time is: the time after the start of the detection, or the detection The time before the end point, or the time window between the detection start point and the detection end point. The detection time may be notified to the terminal device through the network device, and / or may be calculated by the terminal device, or may be predefined, which is described below.

In one embodiment, the detection time may be notified to the terminal device through a network device. In this embodiment, the method may further include: (not shown)

The terminal device receives second instruction information sent by the network device, and the second instruction information includes information about the detection time; the second instruction information may be transmitted through radio resource control signaling, system information, MAC signaling, and physical layer. At least one of the control information is sent to the terminal device.

In one aspect, the related information of the detection time includes at least one of information of a detection start point, information of a detection end point, and length information of a time window.

For example, the information of the detection start point and / or the information of the detection end point may be a relative time with respect to a reference time, and the reference time may be one of the following time: the last symbol of the uplink scheduling request information; uplink scheduling authorization control information The last symbol of the third time-frequency resource; the last symbol of the third time-frequency resource.

For example, the length information of the time window may be absolute length information of the time window or relative length information relative to the time length of the third time-frequency resource.

The unit of the relative time, the unit of the absolute length of the time window, and the unit of the relative length may be one or a combination of at least two of seconds, milliseconds, microseconds, symbols, time slots, and subframes. This embodiment This is not a limitation.

On the one hand, the related information of the detection time includes: an information of the detection start point, and / or information of the detection end point, and / or an index of a combination of length information of the time window, wherein the detection time can be uniquely determined according to the index, the index and The mapping relationship of the detection time may be predefined or pre-configured by the network device to the terminal device, which is not limited in this embodiment.

In this embodiment, when the second indication information includes information of a detection start point, the terminal device detects the interruption indication information from the detection start point, or the terminal device is within a default time window from the detection start point. The interrupt indication information is detected.

In this embodiment, when the second indication information includes information on the detection end point, the terminal device detects the interruption indication information before the detection end point, or the terminal device is within a default length time window before the detection end point. The interrupt indication information is detected.

In this embodiment, when the second indication information includes information of a detection start point and a detection end point, the terminal device detects the interruption indication information within a time between the detection start point and the detection end point.

In this embodiment, when the second indication information includes information of a detection start point and length information of a time window, the terminal device detects the interruption indication information within a time window of a length indicated by the length information from the detection start point.

In this implementation manner, when the second indication information includes information of a detection end point and length information of a time window, the terminal device detects the interruption indication information within a time window of a length indicated by the length information before the detection end point.

The above are just examples, and no more examples are given here.

In one embodiment, the detection time may be calculated by the terminal device. In this embodiment, the method may further include: (not shown, optional) The terminal device calculates the starting point and / Or end of detection time.

In this embodiment, the terminal device determines that the detection start point is a point in time before the first interval of the third time-frequency resource is separated by the effective interval, and the detection end point is the last symbol of the third time-frequency resource. The point in time at which the effective interval was previously spaced.

For example, the time domain length of the third time-frequency resource is L, the first symbol position is symbol S, the effective interval is K, the frame number of the system frame where the symbol S is located is SFN, and the detection starting point is:

SFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot + S-K

Among them, numberOfSlotsPerFrame is the number of slots contained in each frame, and numberOfSymbolsPerSlot is the number of symbols contained in each slot.

For example, the time domain length of the third time-frequency resource is L, the last symbol position is the symbol S + L-1, the effective interval is K, the frame number of the system frame where the symbol S is located is SFN, and the detection end point is:

SFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot + S + L-1-K

The meaning of the effective interval and the embodiment will be described below.

In this embodiment, the terminal device detects the interruption indication information sent by the network device at the detection time, and when the interruption indication information is detected (that is, received), there is a certain amount of time to stop sending uplink data on the first time-frequency resource. The time interval, which includes the time for processing the interrupt indication information and the response time to stop data transmission, etc. The effective interval is related to the processing capability of the terminal device, in other words, the interval before a data symbol on the third time-frequency resource When the interruption indication information is not detected at the time when the effective time is reached, the terminal device cannot stop the uplink transmission of the data, that is, it will send the uplink data according to the resource indicated by the first indication information.

In one embodiment, the terminal device determines the effective interval according to its capability. For example, the capability (the ability to report the PUSCH preparation time N2) and the effective interval have a predefined relationship. According to N2, the effective interval can be determined implicitly. For example, the effective interval is predefined as 50% of N2, which is only an example here, or the method may further include: (not shown, optional) the terminal device may send a capability report to the network device, and the capability report includes Information about the effective interval. The related information may be relationship information of the effective interval to N2, for example, the related information is a percentage of the effective interval of N2 or an effective interval of X symbols is less than N2, etc., and this is merely an example. In this embodiment, the effective interval is the shortest effective interval, that is, the shortest time interval between the last symbol of the interrupt indication information and the time when the terminal device can stop the transmission of the uplink data symbol. The capability report of the effective interval may be used for the network device to determine whether to send interrupt indication information for instructing the terminal device to interrupt sending uplink data. Based on the effective interval in the capability report, the network device can determine whether the terminal device is capable of receiving the interrupt indication information (for example, the time interval between the time when the interrupt instruction information is expected to be sent and the interrupt target (data on the interrupt resource) is less than the effective Time, even if the network device sends the interrupt indication information, the terminal device can stop sending the uplink data at least after the effective interval, but at this time, the uplink data may have been sent within the effective interval.) When the terminal device is capable, , The interrupt indication information is sent, otherwise the interrupt indication information is not sent, and thus, downlink resources can be saved.

In one embodiment, the method may further include: (not shown, optional) the terminal device may receive the third instruction information of the effective interval sent by the network device, and the terminal device determines the effective interval according to the third instruction information The third indication information may be sent to the terminal device through at least one of radio resource control signaling, system information, MAC CE signaling, and physical layer control information.

For example, the network device can configure a set of effective intervals through RRC signaling, and one of the effective intervals is activated by MAC or CE signaling, or an effective interval is indicated by control information. The control information may be public control information or uplink scheduling authorization control information. This embodiment is not limited to this.

In this embodiment, the method may further include (optional): the terminal device reports related information of the effective interval (shortest effective interval), the network device configures the effective interval according to the shortest effective interval, and passes the third instruction information Configure and / or instruct the terminal device.

In this embodiment, the terminal device detects the interruption indication information from the calculated detection starting point, or the terminal device detects the interruption indication information within a time window of a default length from the calculated detection starting point, or the The terminal device detects the interruption indication information before the calculated detection end point, or the terminal device detects the interruption indication information within a default time window before the calculated detection end point, or the terminal device starts from the calculated detection start point The interruption indication information is detected before starting to the end of the detection of the calculation.

In one embodiment, the detection time may be predefined, for example, the length of the time window may be a default length, or it may be defaulted that the length of the time window is equal to the time length of the third time-frequency resource.

On the one hand, the detection start point and / or the detection end point may be one of the following times: the last symbol of the uplink scheduling request information; the last symbol of the uplink scheduling grant control information; the first symbol of the third time-frequency resource ; The last symbol of the third time-frequency resource.

On the one hand, the detection start point and / or the detection end point may be a relative time relative to a reference time, which may be one of the following times: the last symbol of the uplink scheduling request information; the last one of the uplink scheduling authorization control information Symbol; the first symbol of the third time-frequency resource; the last symbol of the third time-frequency resource, the relative time may be predefined and may be determined by a user's processing capability. This embodiment is not limited thereto.

In one embodiment, the detection time may also be determined through at least two combinations of terminal device calculation, pre-defined, and network device notification methods. For example, the terminal device calculates the detection end point, and the network device notifies the detection start point or time window. The time window length is a default value; or the terminal device calculates the detection start point, the network device notifies the detection end point, or the time window, and the terminal device detects the interruption indication information within the time window notified by the network device starting from the calculated detection start point; or The terminal device detects the interruption indication information within a time window notified by the network device before the calculated detection end point; or the terminal device detects the time from the detection start point of the calculation / notification to the notification / calculation detection end point. Interrupt indication information, no longer one by one here.

Embodiments of the interrupt instruction information will be described below.

In this embodiment, the interruption indication information may be included in public control information sent by the network device to the terminal device, or the interruption indication information may be user-specific control information, or the interruption indication information may be sent by the network device to the terminal device. The reference signal is described in detail below.

In one embodiment, the interruption indication information is included in the common control information, and the common control information is that all service terminal devices in the cell or a group of service terminal devices can receive the decoded control information.

For example, the interrupt indication information may be a resource indication value (RIV) of a first number of bits, where the RIV is used to indicate a starting resource interruption unit and the number of resource interruption units included in the first time-frequency resource, such as The RIV indicates the initial resource interruption unit and the number of the resource interruption unit by a triangular binary tree method. The specific i manner is similar to the RIV indication manner in the prior art, and details are not described herein again.

For example, the interruption indication information may reuse a resource allocation manner when performing data scheduling in the prior art.

For example, the interrupt indication information may be a first number of bitmap bitmaps, used to indicate whether the first number of resource interruption units after the last symbol carrying the common control information is the first time-frequency Resource, one bit of the bitmap indicates whether a corresponding resource interruption unit is the first time-frequency resource.

In this implementation manner, the resource interruption unit may be an uplink transmission resource and / or a downlink transmission resource, which is not limited in this embodiment. The resource interruption unit is a predetermined bandwidth in the frequency domain and a second in the time domain. Time-frequency resources of the number of OFDM symbol times.

For example, the first number is 7, the resource interruption unit is a time-frequency resource of 2 OFDM symbols (the frequency domain width is the frequency domain size of the OFDM symbol), and the 7-bit bitmap can indicate whether 14 OFDM symbols are the first Time-frequency resources (whether transmission was interrupted),

The bitmap only indicates the uplink transmission resource, that is, the resource interruption unit is the uplink transmission resource, then the first symbol position of the 14 OFDM symbols is the next uplink symbol of the last symbol occupied by the common control information, that is, the first bitmap One bit indicates whether the two uplink symbols starting with the next uplink symbol are the first time-frequency resource.

Or, the bitmap indicates 14 consecutive OFDM symbols starting from the next symbol of the last symbol occupied by the common control information, that is, the resource interruption unit is not limited to whether it is an uplink resource or a downlink resource.

A bit value of 0 in the bitmap indicates that the corresponding 2 OFDM symbols are not interrupted, that is, it is not the first time-frequency resource, and a bit value of 1 indicates that the corresponding 2 OFDM symbols are interrupted, that is, For the first time-frequency resource, the two OFDM symbols may be an uplink symbol and / or a downlink symbol, which is not limited in this embodiment.

In this embodiment, the first quantity and / or the second quantity are default values or the method may further include: (not shown, optional) high-level signaling and broadcast information sent by the terminal device through the network device At least one of the physical layer control information obtains the first number and / or the second number. For example, the network device configures the second quantity through RRC signaling, and the first quantity is a default value; or the network equipment configures the first quantity through RRC signaling, and configures the second quantity through broadcast information. For example, the first number and the second number are greater than 1 or equal to 1.

In one embodiment, the interrupt indication information may be user-specific control information.

In one example, the user-specific control information indicates that the first time-frequency resource is the third time-frequency resource indicated in step 201. In this example, the user-specific control information includes the HARQ process of the uplink data in step 201. Sequence number, that is, after the terminal device receives the first indication information in step 201 and before the data transmission ends, if it receives user-specific control information including the HARQ process sequence number of the uplink data, the user-specific information is used as the interrupt indication information. , Indicating that the first time-frequency resource is the third time-frequency resource, which means that the priority of the user-specific control information is higher than the first indication information, and the terminal device stops sending the uplink data on the third time-frequency resource.

In this example, the network device may further reallocate a second time-frequency resource for transmitting the uplink data to the terminal device. The user-specific control information may further include: indication information of the second time-frequency resource. In step 203 The terminal device sends the uplink data on a second time-frequency resource that does not include the first time-frequency resource.

In another example, the user-specific control information includes first time-frequency resource indication information, and the first time-frequency resource indication information indicates that the integer number of resource interruption units included in the third time-frequency resource is the first time-frequency resource. In other words, the first time-frequency resource indication information indicates which resource interruption unit in the third time-frequency resource is the first time-frequency resource, that is, which resource interruption unit in the third time-frequency resource. No uplink data can be transmitted. The first time-frequency resource indication information is a resource indication value (RIV) of a third number of bits or a bitmap of a third number of bits. For a method of determining the third number, refer to the first The number and the second number are not repeated here.

For example, the time domain length of the third time-frequency resource is a third number of OFDM symbols (one OFDM symbol corresponds to one resource interruption unit), and the first time-frequency resource indication information indicates which of the OFDM symbols (hereinafter referred to as interrupted OFDM) Symbol) as the first time-frequency resource, the interrupted OFDM symbol may be indicated by using a bitmap of a third number of bits, where each bit indicates whether one of the corresponding third number of OFDM symbols is the interrupt OFDM symbol, for example, a bit value of 0 indicates that the OFDM symbol can be used to send uplink data, a bit value of 1 indicates that the OFDM symbol is an interrupted OFDM symbol, and the first time-frequency resource indication information can indicate the third time-frequency The interruption situation of each resource interruption unit in the resource (whether it is interrupted or not, or whether it is the first time-frequency resource). The implementation manner of the resource interruption unit is as described above. This embodiment does not use this as a limitation. The indication method is similar to the implementation of the interrupt indication information RIV in the public control information, and no further examples are given here.

In this example, the user-specific control information further includes indication information of a fourth time-frequency resource; the fourth time-frequency resource may be a time-frequency resource reallocated by the network device to the terminal device, and is used to send the information originally indicated as Part of the uplink data sent on the third time-frequency resource of the first time-frequency resource, and the remaining part of the data is also sent on the third time-frequency resource that was not originally designated as the first time-frequency resource, that is, in step 203 The terminal device sends the uplink data on a second time-frequency resource, and the second time-frequency resource is a resource set consisting of resources other than the first time-frequency resource and the fourth time-frequency resource in the third time-frequency resource That is, the second time-frequency resource does not include the first video resource.

In an embodiment, the interrupt indication information may be a reference signal, and the first time-frequency resource may be indicated by a symbol sequence constituting the reference signal and / or a set of resource elements mapping the reference signal. The first time-frequency resource is the following one of the resource interruption units or the fourth number of the resource interruption units. For example, the reference signal may be the same as the DMRS used for PDSCH demodulation, and / or, the resource mapping mode of the reference signal is the same as that of DMRS used for PDSCH demodulation, and the reference signal may also be other types of reference. The signal is not limited in this embodiment.

In this embodiment, the existing reference signal is reused, which can reduce the complexity of the system

In an example, the reference signal indicates that the first time-frequency resource is a resource interruption unit that is separated by a valid interval after the symbol time where the reference signal is located; when the terminal device detects the reference signal, the A resource interruption unit after an effective interval after the symbol time is interrupted. The resource interruption unit is as described above, and is not repeated here.

In one example, the reference signal indicates that the first time-frequency resource is a fourth number of the resource interruption units, and the start position of the fourth number of the resource interruption units is an interval after a symbol time where the reference signal is located. Resource interruption unit for an effective interval. The fourth number of resource interruption units may specifically be determined according to a sequence symbol mapped to the reference signal and / or a set of resource elements mapped to the reference signal.

The following uses the above DMRS reference signal as an example to describe how to determine the fourth number of resource interruption units.

FIG. 3A and FIG. 3B are schematic diagrams of DMRS configuration type 1 and DMRS configuration type 2 in the existing NR system (different mapping patterns, mapping the set of resource elements of the reference signal). As shown in FIG. 3B, DMRS configuration type 1 is frequency Each subcarrier of an interval of a subcarrier in the domain is divided into the same group, which is divided into two sets of subcarriers. On the same group, the antenna ports are orthogonal through the frequency domain orthogonal mask. When an OFDM symbol is configured, each Group subcarriers map up to two DMRS antenna port reference signals, that is, a configuration type 1 of an OFDM symbol supports a maximum of four orthogonal DMRS antenna ports. As shown in FIG. 3B, in the DMRS configuration type 2, two consecutive subcarriers in the frequency domain are divided into one group, which is divided into three sets of subcarriers. When an OFDM symbol is configured, each group maps a maximum of two DMRS antennas. The reference signal of the port is guaranteed to be orthogonal by a frequency division orthogonal sequence of length 2. Therefore, a configuration type 2 of one OFDM symbol supports a maximum of six orthogonal DMRS antenna ports.

For example, when a DMRS of 1 OFDM symbol of type 1 is configured as the interruption indication information, the OFDM symbol may carry whether four consecutive resource interruption units indicated by the OFDM symbol sequence of 4 antenna ports are the first time-frequency resource, The position after the DMRS transmission position is separated by a valid interval indicates the start position of the fourth number of resource interruption units, and the DMRS sequence corresponding to port 1 and the set of mapped resource elements indicate the fourth number of resource interruption units. The first resource interruption unit in is the first time-frequency resource. The DMRS sequence corresponding to port 2 and the set of mapped resource elements indicate that the first two resource interruption units in the fourth number of resource interruption units are the first time-frequency resource. Frequency resource, the DMRS sequence corresponding to port 3 and the mapped resource element set indicate that the third resource interruption unit is the first time-frequency resource, and the DMRS sequence corresponding to port 4 and the mapped resource element set indicate the last two resource interruption units are The first time-frequency resource;

Or, in order to enhance the reference signal transmission power and signal strength, the first group and the second group of subcarrier sets are transmitted at different times, that is, the DMRS sequence received on the first group of subcarrier sets indicates the first or first two The resource interruption unit is the first time-frequency resource. The DMRS sequence received on the second set of subcarriers indicates that the first three or all four resource interruption units are the first time-frequency resource. Implementation of the resource interruption unit As mentioned before, we will not repeat them here.

In the above, one OFDM symbol is configured as an example, but this embodiment is not used as a limitation.

In this embodiment, the reference signal is scrambled by a scrambling code sequence dedicated to the interrupt indication, which means that the reference signal can be used as the interrupt indication information.

In this embodiment, in step 201, the terminal device detects the interruption indication information at the detection time period at a predetermined period. Therefore, at least two interrupt indication information may be detected. When the first time-frequency resources indicated by the at least two interrupt indication information overlap, the reliability of the interrupt indication may be enhanced.

In this embodiment, in step 201, when at least two interrupt indication information are detected, and the at least two interrupt indication information indicate that the interrupt conditions on the same resource are different, the terminal device interrupts according to the first or last interrupt. The indication information determines the first time-frequency resource. For a resource interruption unit, if one interruption indication information indicates that the unit is the first time-frequency resource, and another interruption indication information indicates that the unit is not the first time-frequency resource, the first The first or last detected interrupt indication information is used as a reference, that is, uplink data is not sent on the first time-frequency resource indicated in the first or last detected interrupt indication information.

When at least two interrupt indication information are detected, and there is one interrupt indication information indicating a predetermined time-frequency resource as the first time-frequency resource, the terminal device determines the predetermined time-frequency resource as the first time-frequency resource. For a resource interruption unit, if there is an interruption indication information indicating that the unit is a first time-frequency resource, and other interruption indication information indicates that the unit is not the first time-frequency resource, that is, the resource interruption unit is used as the first time-frequency resource, The terminal equipment does not send uplink data on this interruption unit.

In an implementation manner, the uplink scheduling request sent by the high-priority terminal device includes an uplink time-frequency resource that it needs to send high-priority data, and the network device according to the uplink time-frequency sent by the high-priority terminal device The resource determines the first time-frequency resource, so as to meet the low-latency requirement of the high-priority terminal device.

In an implementation manner, the terminal device determines whether to stop sending the uplink data according to whether the first time-frequency resource includes a preload demodulation reference signal of the uplink data.

In one example, the first time-frequency resource includes resources that carry the front-loaded demodulation reference signal (front-loaded DMRS) in the third time-frequency resource, and the second time-frequency resource does not include the uplink data. When the resources of the additional demodulation reference signal (Additional DMRS) are used, the terminal device stops sending the uplink data.

In one example, the first time-frequency resource includes a resource carrying the front-loaded demodulation reference signal (front-loaded DMRS) in the third time-frequency resource, and the second time-frequency resource includes the uplink data. When the resources of the additional demodulation reference signal (Additional DMRS) are used, the terminal device sends the uplink data on the second time-frequency resource.

According to the foregoing embodiment, the method for detecting the interrupt indication information and the interrupt indication information at the detection time by the terminal device is proposed, which can solve the problem of how to instruct the interrupt transmission in the uplink data transmission, and can ensure that the low-priority terminal device detects the interrupt indication with low power consumption. Information and data transmission on some resources are interrupted while avoiding mutual interference, thereby ensuring the reliability or delay requirement of uplink data transmission of high-priority terminal equipment, and improving resource utilization.
