Description
Technical Field
The embodiment of the application relates to the field of wireless communication, in particular to a method and a device for indicating resources.
Background
With the development of mobile communication technology, fifth generation (the fifth generation, 5G) mobile communication technology has become a hotspot for global development. The mobile internet and the internet of things are used as main driving forces for future communication development, and can have great influence in the fields of people living, working, leisure, traffic and the like, and the 5G business demands are diversified. For example, in an industrial control scenario, the controller needs to maintain time synchronization with the actuators. The controller sends control signaling to the executor to instruct the executor to execute the command at the determined time, and if the cognition of the executor and the controller to the time is different, namely the executor is not synchronous, the executor can execute the command at the wrong time, so that the task execution fails. The network device is used as a centralized controller of the terminal device, and can be used as a time synchronization source of the terminal device to send indication information to the terminal device, so that all the terminal devices in the cell are kept in time synchronization with the network device, and the time synchronization between the terminal devices is indirectly achieved.
The network device and the terminal device may periodically interact with time information (e.g., time-dependent network (time sensitive networking, TSN) information) to adjust the clock to maintain time synchronization based on the time information. For example, TSN information is transmitted on configured resources such as unlicensed grant (CG) resources or semi-persistent scheduling (semi-persistent scheduling, SPS) resources. However, since the service period (for example, the period of the TSN information) is different from the period of the configuration resource, if the service arrival time is different from the time of transmitting the configuration resource after the service arrives, the TSN information is transmitted after the time of transmitting the configuration resource. In some embodiments, as shown in (a) in fig. 1, the period of the configuration resource is greater than the service period, and the delay of transmitting time information is greater; as shown in fig. 1 (b), if the period of the configuration resources is smaller than the service period, some configuration resources (such as resources corresponding to the time of "x" in the drawing) will not transmit the service period, and the configuration resources are wasted. Therefore, how to improve the utilization rate of system resources is a problem to be solved.

In embodiments of the application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
Mobile communication technology has drastically changed people's lives, but the pursuit of higher performance mobile communication technology has never stopped. In order to cope with the future explosive mobile data flow increase, equipment connection of mass mobile communication and various new services and application scenes which are continuously emerging, a 5G mobile communication system is generated. The 5G mobile communication system is also called a new radio access technology (new radio access technology, NR) system. The international telecommunications union (international telecommunication union, ITU) defines three general classes of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (enhanced mobile broadband, emmbb), URLLC, mass machine type communication (massive machine type communications, mctc), multimedia broadcast multicast service (Multimedia Broadcast Multicast Service, MBMS), and location services, among others. Deployment scenarios include Indoor hotspots (industry hotspots), dense Urban areas (Urban), suburban areas, urban Macro coverage (Urban Macro), and high-speed rail scenarios.
Typical eMBB services include ultra-high definition video, augmented reality (augmented reality, AR), virtual Reality (VR), and the like. The main characteristics of these services include large data volume and high transmission rate.
Typical mctc services include smart grid distribution automation, smart cities, and the like. The main characteristics of these services include the large number of networking devices, the small amount of data transmitted and the insensitivity of data to transmission delay. These mctc terminals need to meet the demands of low cost and very long standby time.
Typical URLLC services include wireless control in industrial manufacturing or production processes, motion control of unmanned vehicles and unmanned aircraft, and haptic interactive applications such as remote repair and tele-surgery. The main characteristics of these services are the requirement of ultra high reliability, low latency, small amount of data to be transmitted and burstiness. For example, vehicle-to-outside information exchange (vehicle to everything, V2X) requires a reliability of 99.999% with an end-to-end delay of 5 milliseconds (ms); the power distribution (power distribution) needs to have a reliability of 99.9999% and an end-to-end delay of 5ms; the factory automation (factory automation) reliability was 99.9999% and the end-to-end delay was 2ms.
In long term evolution (long term evolution, LTE) systems, the smallest time scheduling unit is a transmission time interval (transmission time interval, TTI) of 1ms in time length. The 5G not only supports time domain scheduling granularity of time unit level, but also can support time domain scheduling granularity of micro time unit, and can meet the time delay requirements of different services. For example, time units are mainly used for the emmbb traffic and micro time units are mainly used for the URLLC traffic. It should be noted that the above time units and micro time units are general terms, and a specific example may be that a time unit may be referred to as a slot, and a micro time unit may be referred to as a micro slot, a non-slot-based, a mini-slot, or a symbol (symbol); alternatively, a time unit may be referred to as a subframe, and a micro-time unit may be referred to as a micro-subframe; other similar time domain resource partitioning methods are not limited. Wherein, a time slot may include 14 time domain symbols, and a mini time slot includes less than 14 time domain symbols, such as 2, 3, 4, 5, 6 or 7, etc.; or, for example, a time slot may include 7 time domain symbols, and a mini time slot includes less than 7 time domain symbols, such as 2 or 4, and the specific value is not limited.

For one time unit with a subcarrier spacing of 120kHz, the period of the configuration resources may include 2 time domain symbols, 7 time domain symbols, and n×14 symbols, n= {1,2,4,5,8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 256, 320, 512, 640, 1024, 1280, 2560, 5120}.

Next, a method of resource indication will be described in detail. In a first possible implementation, the first time-frequency resource may be indicated by the indication information, and the network device or the terminal device receives or transmits data on the indicated first time-frequency resource. Fig. 4 is a flowchart of a method for indicating resources according to an embodiment of the present application. As shown in fig. 4, the method may include:
s401, the network equipment sends first indication information to the terminal equipment, wherein the first indication information is used for indicating M first time-frequency resources in N first time-frequency resources.
In some embodiments, the network device may send the first indication information to the terminal device through higher layer signaling. Higher layer signaling may refer to signaling by higher layer protocol layers. The higher protocol layer is at least one protocol layer above the physical layer. The higher layer protocol layers may include at least one of the following protocol layers: a medium access control (medium access control, MAC) layer, a radio link control (radio link control, RLC) layer, a packet data convergence protocol (packet data convergence protocol, PDCP) layer, a radio resource control (radio resource control, RRC) layer, and a non-access layer (non access stratum, NAS).
For example, the network device may send the first indication information to the terminal device through RRC signaling. Alternatively, alternatively described as: the network device sends an RRC signaling to the terminal device, the RRC signaling including the first indication information.
In some embodiments, the network device may send the first indication information to the terminal device through physical layer signaling. Such as downlink control signaling (dynamic control indication, DCI).
The first indication information is used for indicating M first time-frequency resources in N first time-frequency resources, wherein N and M are positive integers, and each first time-frequency resource in the M first time-frequency resources is used for transmitting data.
In one possible design, the first indication information may be a bit sequence, through which M first time-frequency resources of the N first time-frequency resources are indicated. For example, the first indication information may be a bitmap, which may include N bits. If the bits of the M bits of the N bits are 1, it may be indicated that each of the first time-frequency resources indicated by the M bits is used for transmitting data, and the bits of the N-M bits of the N bits are 0, it may be indicated that each of the first time-frequency resources indicated by the N-M bits is not used for transmitting data. If the bits of the M bits of the N bits are 0, it may be indicated that each of the first time-frequency resources indicated by the M bits is used for transmitting data, and the bits of the N-M bits of the N bits are 1, it may be indicated that each of the first time-frequency resources indicated by the N-M bits is not used for transmitting data. Alternatively, the value of N is also indicated in the first information.
Alternatively, the first time-frequency resource not used for transmitting data may transmit other service information or service information of other users, which is not limited by the present application.
S402, the terminal equipment receives the first indication information sent by the network equipment.
The first indication information is used for indicating M first time-frequency resources in N first time-frequency resources, and each first time-frequency resource in the M first time-frequency resources is used for transmitting data. The detailed explanation of the first indication information may refer to the explanation of S401, and will not be repeated.
In some embodiments, when the network device sends data to the terminal device, the data may be sent on a first time-frequency resource indicated by the first indication information, where the data may be downlink data, and the first time-frequency resource may be PDSCH. Specifically, the explanation of the details of the network device transmitting data to the terminal device is referred to in S403 and S404.
S403, the network equipment sends data to the terminal equipment on M first time-frequency resources in the N first time-frequency resources by taking the N first time-frequency resources as a period.
It is particularly emphasized that in the present application, the data transmitted to the terminal device on M first time-frequency resources of the N first time-frequency resources may be M data. Each data in the M data may be 1 data Transport Block (TB), or may be 1 group of data transport blocks, where the 1 group of data transport blocks may be multiple repetitions of one transport block, or may be multiple transport blocks, which will not be described in detail later.
In some embodiments, starting from the first starting time, data is transmitted on M first time-frequency resources within each resource cycle period with N first time-frequency resources as resource cycle periods. The first starting time is the starting time of transmitting the first time-frequency resource. Each data information transmitted on the first time-frequency resource may be the same or different, and is not limited.
S404, the terminal equipment receives the data sent by the network equipment on M first time-frequency resources in the N first time-frequency resources by taking the N first time-frequency resources as a period.
In some embodiments, the terminal device may determine the time to transmit the first time-frequency resource according to a first starting time and a first period, where the first starting time is the starting time to transmit the first time-frequency resource, and the first period is the period to transmit the first time-frequency resource. After the terminal equipment receives the first indication information, starting from the first starting time, receiving data on M first time-frequency resources in each resource cycle period by taking N first time-frequency resources as resource cycle periods. The data received on the first time-frequency resource may be M data, which may be the same or different. Each data in the M data may be 1 TB or 1 group of data transport blocks, where the 1 group of data transport blocks may be multiple repetitions of one transport block or multiple transport blocks, which will not be described in detail later.
In other embodiments, when the terminal device sends data to the network device, the data may be sent on a first time-frequency resource indicated by the first indication information, where the data may be uplink data, and the first time-frequency resource may be PUSCH. Specifically, the explanation of the details of the terminal device transmitting data to the network device is referred to in S405 and S406.
And S405, the terminal equipment sends data to the network equipment on M first time-frequency resources in the N first time-frequency resources by taking the N first time-frequency resources as a period.
In some embodiments, after the terminal device receives the first indication information, starting from the first starting time, data is sent on M first time-frequency resources in each resource cycle period with N first time-frequency resources as resource cycle periods.
S406, the network equipment receives data sent by the terminal equipment on M first time-frequency resources in the N first time-frequency resources by taking the N first time-frequency resources as a period.
In some embodiments, starting from the first starting time, M data are received on M first time-frequency resources within each resource cycle period with N first time-frequency resources as resource cycle periods.
According to the resource indication method provided by the embodiment of the application, the network equipment and the terminal equipment can receive or send the data on the appointed first time-frequency resource by indicating the first time-frequency resource for sending the data, so that the utilization rate of the configuration resource is effectively improved.
In addition, since the first time-frequency resource is a semi-static resource, the receiving end (network device or terminal device) can perform blind detection on the first time-frequency resource to receive data. If the receiving end performs blind detection on all the configured first time-frequency resources, some first time-frequency resources do not bear data, which results in wasting the power consumption of the receiving end. The method for resource indication provided by the embodiment of the application has the advantages that the receiving end performs blind detection on the first time-frequency resources indicated by the first indication information to receive data, so that blind detection on all configured first time-frequency resources is avoided, the utilization rate of the time-frequency resources is effectively improved, and the power consumption of the receiving end is saved. The embodiment of the application provides a method for determining resource allocation, which selects the minimum resource circulation period and the minimum resource use number on the premise of meeting the data transmission delay, thereby reducing the expenditure of indication information and improving the utilization rate of system resources. Moreover, by adopting the method provided by the embodiment of the application, the service and the resource period can be better matched, and the deviation of the understanding of the receiving end and the sending end on the available resources is avoided, so that the time delay and the reliability of the service are ensured.
In some embodiments, N and M may be determined by the network device based on the first start time, the first period, the second start time, and the second period. The second starting time is the starting time of the service period of the data. The second period is a traffic period of the data. Since after the service arrives, if the time of the service arrives is different from the time of transmitting the first time-frequency resource, the data is transmitted after waiting for the time of transmitting the first time-frequency resource. In order to ensure the time delay of transmitting data and avoid the situation that a certain service is not transmitted yet and the next service arrives, the first period is set smaller than the second period. As shown in fig. 5, S501 is performed before the first indication information, S401, is transmitted.
S501, the network equipment determines M first time-frequency resources in the number N of the first time-frequency resources according to the first starting time, the first period, the second starting time and the second period.
Since the arrival time of the service and the transmission time of the first time-frequency resource are both periodically appeared, the difference between the arrival time of the service and the transmission time of the first time-frequency resource also presents a periodic rule. In some embodiments, the network device may determine the specific values of N and M from the first period and the second period. N and M satisfy the following formula (1).
P_tr*M＝P_re*N (1)
Where p_tr denotes the second period and p_re denotes the first period.
Further, after the network device determines the specific values of N and M, M first time-frequency resources for transmitting data in the N first time-frequency resources are determined. Assuming that the second starting time is the starting time of the service period of the data, the second starting time is the same as the first starting time, that is, the time when the first service arrives is the same as the time when the first time is the first time when the first time is sent, the first time frequency resource corresponding to the first starting time can be determined as the first time frequency resource for transmitting the data, then, the first time-frequency resource corresponding to the time of the first time-frequency resource closest to the time of arrival of the traffic is determined as the first time-frequency resource of the transmission data, and so on, thereby determining M first time-frequency resources in the N first time-frequency resources.
Alternatively, the second period may be configured in advance for the network device and the terminal device. Thus, the network device need not acquire the second period from the other network elements. Or acquiring a second period before transmitting data through information interaction between the terminal equipment and the network equipment.
In the following, an example of determining M first time-frequency resources in the number N of first time-frequency resources is described, taking the second period of 0.833ms as an example. In order to ensure the delay of transmitting data, a suitable first time-frequency resource is searched in the first time-frequency resources smaller than 0.833 ms. For example, for one slot with a subcarrier spacing of 15kHz, the time length of 2 symbols is 1/7ms, the time length of 7 symbols is 0.5ms, and the time length of 14 symbols is 1ms, so the value of the first period may be 0.5ms or 1/7ms.
When the first period is 0.5ms and the second period is 0.833ms, substituting 0.5ms and 0.833ms into formula (1), i.e., p_re=0.5 ms=1/2 ms, p_tr=0.833 ms=5/6 ms, the smallest M and N established by 5/6*M =1/2*N are selected, then m=3, n=5. M and N satisfy the relationship of mutual quality.
When the first cycle is 1/7ms and the second cycle is 0.833ms, substituting 1/7ms and 0.833ms into equation (1), i.e., p_re=1/7 ms, p_tr=0.833 ms=5/6 ms, selecting the smallest M and N that 5/6*M =1/7*N holds, then m=6, n=35. M and N satisfy the relationship of mutual quality.
Therefore, on the premise of ensuring the data transmission delay, selecting M and N with the shortest resource cycle period or further considering M and N with the smallest configuration resource number in the resource cycle period, determining that M=3 and N=5, wherein the first period is 0.5ms. As shown in fig. 6, a schematic diagram of the transmitted data. The time instant at which the first time-frequency resource is transmitted may be 0, 0.5, 1, 1.5, 2, 2.5, etc. Data is not transmitted on the first time domain resource corresponding to the time of drawing 'x'.
As shown in table 1, the specific time of transmitting the data.
TABLE 1
| Service sequence number | Service arrival (ms) | Time of day (ms) of transmitting a first time domain resource | Time delay (ms) |
| 0 | 0 | 0 | 0 |
| 1 | 0.833333 | 1 | 0.166667 |
| 2 | 1.666667 | 2 | 0.333333 |
| 3 | 2.5 | 2.5 | 0 |
| 4 | 3.333333 | 3.5 | 0.166667 |
| 5 | 4.166667 | 4.5 | 0.333333 |
| 6 | 5 | 5 | 0 |
| 7 | 5.833333 | 6 | 0.166667 |
| 8 | 6.666667 | 7 | 0.333333 |
| 9 | 7.5 | 7.5 | 0 |
| 10 | 8.333333 | 8.5 | 0.166667 |
| 11 | 9.166667 | 9.5 | 0.333333 |
As can be seen from fig. 6 and table 1, the traffic number 0 indicates that the 1 st data arrives, the arrival time of the 1 st data arrives is 0ms, the time of transmitting the first time domain resource is 0ms, and the time of transmitting the 1 st data is 0ms. The service number 1 indicates that the 2 nd data arrives, the arrival time of the 2 nd data arrives is 0.833333ms, the time of transmitting the first time domain resource is 1ms, and the time of the 2 nd data transmission is 1ms. The delay was 0.166667. The service number 2 indicates that the 3 rd time arrives, the arrival time of the 3 rd time arrives is 1.666667ms, the time of transmitting the first time domain resource is 2ms, and the time of the 3 rd time of transmitting the data is 2ms. The delay was 0.333333. Data is not transmitted on the first time-frequency resource corresponding to 0.5ms and the first time-frequency resource corresponding to 1.5ms, and the data is circulated in sequence.
Thus, every 5 first time-frequency resources is one resource cycle period. For each resource cycle period, data is transmitted or received on the first time-frequency resource, the third first time-frequency resource, and the fifth first time-frequency resource, and data is not transmitted on the second first time-frequency resource and the fourth first time-frequency resource.
Thus, the first indication information may indicate 3 first time-frequency resources among the 5 first time-frequency resources. If the first indication information is a bitmap, the bitmap is 10101. Or the value of N is also indicated in the first information.
By way of example, assuming a second period of 16.67 ms=100/6 ms, selecting a value for the first period that is less than the second period, such as 5ms, 8ms or 10ms, can result in values of M and N according to equation (1) as shown in table 2. Finally, it can be determined that the smallest combination m=3, n=5 is selected
TABLE 2
| First period of | M | N |
| 10 | 3 | 5 |
| 8 | 12 | 25 |
| 5 | 3 | 10 |
Therefore, on the premise of ensuring the data transmission delay, selecting the M and the N with the shortest resource cycle period, or further considering the M and the N with the smallest configuration resource number in the resource cycle period, the M=3 and the N=5 can be determined, and the first period is 10ms. The first indication information may indicate 3 first time-frequency resources among the 5 first time-frequency resources. Every 5 first time-frequency resources are one resource cycle period. For each resource cycle period, data is transmitted or received on the second first time-frequency resource, the fourth first time-frequency resource, and the fifth first time-frequency resource, and data is not transmitted on the first time-frequency resource and the third first time-frequency resource. If the first indication information is a bitmap, the bitmap is 01011. Or the value of N is also indicated as 5 in the first information.
Further, before the network device sends the first indication information to the terminal device, the network device may configure the first time-frequency resource for the terminal device, so that the terminal device receives or sends data on the first time-frequency resource. As shown in fig. 5, S502 to S503 are executed before S501.
S502, the network equipment sends first resource configuration information to the terminal equipment.
In some embodiments, the network device may send the first resource configuration information to the terminal device through higher layer signaling. For example, the network device may send the first resource configuration information to the terminal device through RRC signaling. For example, the higher layer parameters configuredGrantConfig, configuredGrantConfig in the RRC signaling include RRC-configurable uplink Grant. The first resource configuration information is rrc-configurable uplink grant. The first resource configuration information includes a first start time and a first period.
S503, the terminal equipment receives the first resource configuration information sent by the network equipment.
In some embodiments, after receiving the first resource configuration information, the terminal device may send or receive data on the periodically configured first time-frequency resource. In other embodiments, after receiving the first resource configuration information and then receiving the downlink control information (downlink control information, DCI), the terminal device activates a first time-frequency resource configured by the first resource configuration information, and transmits or receives data on the periodically configured first time-frequency resource. The first resource configuration information includes a first start time and a first period. The specific explanation of the first resource configuration information may refer to the explanation of S502, and will not be repeated.
In other embodiments, the network device may configure the terminal device with multiple sets of time-frequency resources on which to receive data. As shown in fig. 7, the method further comprises.
S701, the network equipment sends second resource configuration information to the terminal equipment.
In some embodiments, the network device may send the second resource configuration information to the terminal device through higher layer signaling. For example, the network device may send the second resource configuration information to the terminal device through RRC signaling. For example, the higher layer parameters configuredGrantConfig, configuredGrantConfig in the RRC signaling include second resource configuration information (e.g., RRC-configurable uplink). The second resource configuration information includes a third start time and a third period, the third start time is a start time of transmitting the second time-frequency resource, and the third period is a period of transmitting the second time-frequency resource.
S702, the terminal equipment receives the second resource configuration information sent by the network equipment.
In some embodiments, after receiving the second resource configuration information, the terminal device may send or receive data on the periodically configured second time-frequency resource. In other embodiments, after receiving the second resource configuration information, the terminal device activates a second time-frequency resource configured by the second resource configuration information after receiving the DCI, and transmits or receives data on the periodically configured second time-frequency resource. The second resource configuration information includes a third start time and a third period. The specific explanation of the second resource configuration information may refer to the explanation of S701, which is not repeated.
It should be noted that the sequence of the steps of the method for indicating the resource provided by the embodiment of the application can be properly adjusted. For example, the order of S502 and S701 may be interchanged, that is, the network device may send the second resource configuration information to the terminal device first and then send the first resource configuration information to the terminal device, and any method that is easily conceivable to be changed by those skilled in the art within the technical scope of the present disclosure should be covered within the protection scope of the present disclosure, so that no further description is given.
In some embodiments, the network device may further determine L second time-frequency resources of the number K of second time-frequency resources, i.e. determine a resource cycle period of the second time-frequency resources. As shown in fig. 7, S703 is performed before the first indication information, i.e., S401, is transmitted.
S703, the network device determines L second time-frequency resources in the number K of the second time-frequency resources according to the third starting time, the third period, the second starting time and the second period.
The time of arrival of the service and the time of transmission of the second time-frequency resource are both periodically appeared, so that the difference between the time of arrival of the service and the time of transmission of the second time-frequency resource also presents a periodic law. In some embodiments, the network device may determine K and L according to the third start time, the third period, the second start time, and the second period, where K and L are both positive integers, and K and L satisfy formula (1). Specific reference may be made to S501, which is not described herein.
Thus, the first indication is also used to indicate L second time-frequency resources of the K second time-frequency resources. Each of the L second time-frequency resources is used for transmitting data.
In some embodiments, when the network device sends data to the terminal device, the data may be sent on a second time-frequency resource indicated by the first indication information, where the data may be downlink data, and the second time-frequency resource may be PDSCH. Specifically, the detailed explanation of the network device transmitting data to the terminal device is set forth with reference to the execution S704 and S705.
And S704, the network equipment takes K second time-frequency resources as a period, and sends data to the terminal equipment on L second time-frequency resources in the K second time-frequency resources.
In some embodiments, starting from the third starting time, the data is sent on L second time-frequency resources in each resource cycle period with K second time-frequency resources as resource cycle periods. The number of data to be transmitted on the second time-frequency resource may be one or more, and each of the plurality of data may be the same or different, but is not limited thereto.
And S705, the terminal equipment receives data sent by the network equipment on L second time-frequency resources in the K second time-frequency resources by taking the K second time-frequency resources as a period.
In some embodiments, the terminal device may determine the time of transmitting the second time-frequency resource according to the third start time and the third period. After the terminal equipment receives the first indication information, starting from the third starting moment, receiving M data on L second time-frequency resources in each resource cycle period by taking K second time-frequency resources as resource cycle periods. The data received on the second time-frequency resource may be one or more, and each of the plurality of data may be the same or different, but is not limited thereto.
In other embodiments, when the terminal device sends data to the network device, the data may be sent on a second time-frequency resource indicated by the first indication information, where the data may be uplink data, and the second time-frequency resource may be PUSCH. Specifically, the terminal device transmits data to the network device for detailed explanation with reference to execution of the explanation of S706 and S707.
S706, the terminal equipment takes the K second time-frequency resources as a period, and sends data to the network equipment on L second time-frequency resources in the K second time-frequency resources.
In some embodiments, after the terminal device receives the first indication information, starting from the third starting time, using K second time-frequency resources as resource cycle periods, and sending L data on L second time-frequency resources in each resource cycle period.
And S707, the network equipment takes the K second time-frequency resources as a period, and receives the data sent by the terminal equipment on L second time-frequency resources in the K second time-frequency resources.
In some embodiments, starting from the third starting time, the K second time-frequency resources are taken as resource cycle periods, and the L data are received on the L second time-frequency resources in each resource cycle period.
In one possible design, the first indication information is a bitmap including n+k bits. The bits of the M bits of the N bits indicate a first time-frequency resource of the transmitted or received data. The bits of L bits of the K bits indicate a second time-frequency resource of the transmission or reception data. Or the value of N is also indicated in the first information.
For example, if the bit of the L bits in the K bits is 1, it may indicate that each of the second time-frequency resources indicated by the L bits is used for transmitting data, and the bit of the K-L bits in the K bits is 0, it may indicate that each of the second time-frequency resources indicated by the K-L bits is not used for transmitting data. If the bit of the L bits in the K bits is 0, it may indicate that each of the second time-frequency resources indicated by the L bits is used for transmitting data, and the bit of the K-L bits in the K bits is 1, it may indicate that each of the second time-frequency resources indicated by the K-L bits is not used for transmitting data.
It can be appreciated that m+l data are traffic cycle periods. Data (e.g., M data) is received on M first time-frequency resources and data (e.g., L data) is received on L second time-frequency resources within each traffic cycle period.
By way of example, as shown in fig. 8, a schematic diagram of data is transmitted. The first starting time is 0ms, the first period is 1ms, and the time of transmitting the first time-frequency resource may be an integer millisecond, for example: 0.1, 2, 3, etc. The third starting time is 0.5ms, the third period is 1ms, and the time of sending the second time-frequency resource may be a half integer millisecond, for example: 0.5, 1.5, 2.5, etc. The time instant at which the first time-frequency resource is transmitted differs from the time instant at which the second time-frequency resource is transmitted by 0.5ms. The second period is 0.833ms. Data is not transmitted on the first time domain resource corresponding to the time of drawing 'x'.
As can be seen from fig. 8 and table 1, the traffic number 0 indicates that the 1 st data arrives, the arrival time of the 1 st data arrives is 0ms, the time of transmitting the first time domain resource is 0ms, and the time of transmitting the 1 st data is 0ms.
The service number 1 indicates that the 2 nd data arrives, the arrival time of the 2 nd data arrives is 0.833333ms, the time of transmitting the first time domain resource is 1ms, and the time of the 2 nd data transmission is 1ms. The delay was 0.166667.
The service number 2 indicates that the 3 rd time arrives, the arrival time of the 3 rd time arrives is 1.666667ms, the time of transmitting the first time domain resource is 2ms, and the time of the 3 rd time of transmitting the data is 2ms. The delay was 0.333333. No data is transmitted on the first time-frequency resource corresponding to 3ms and the first time-frequency resource corresponding to 4 ms.
The service number 3 indicates that the 4 th data arrives, the arrival time of the 4 th data arrives is 2.5ms, the time of transmitting the first time domain resource is 2.5ms, and the time of transmitting the 4 th data is 2.5ms.
The service number 4 indicates that the 5 th data arrives, the arrival time of the 5 th data arrives is 3.333333ms, the time of transmitting the first time domain resource is 3.5ms, and the time of transmitting the 5 th data is 3.5ms. The delay was 0.166667.
The service number 5 indicates that the 6 th data arrives, the arrival time of the 6 th data arrives is 4.166667ms, the time of transmitting the first time domain resource is 4.5ms, and the time of transmitting the 6 th data is 4.5ms. The delay was 0.333333. No data is transmitted on the first time-frequency resource corresponding to 0.5ms and the first time-frequency resource corresponding to 1.5 ms. And sequentially circulating.
Thus, every 5 first time-frequency resources is one first resource cycle period. For each first resource cycle period, data is transmitted or received on the first, second and third first time-frequency resources, and no data is transmitted on the fourth and fifth first time-frequency resources. Every 5 second time-frequency resources is a second resource cycle period. For each second resource cycle period, data is transmitted or received on the third first time-frequency resource, the fourth first time-frequency resource and the fifth first time-frequency resource, and no data is transmitted on the first time-frequency resource and the second first time-frequency resource.
Thus, the first indication information may indicate 3 of the 5 first time-frequency resources and 3 of the 5 second time-frequency resources. The bitmap is 1110000111. Or the value of N is also indicated as 10 in the first information.
In another possible design, the first indication information includes an identification of a first time-frequency resource transmitting the M data and an identification of a second time-frequency resource transmitting the L data.
It should be understood that the "transmission" may refer to either transmission or reception. M+l data are the traffic cycle periods. In each service cycle period, M data are received on M first time-frequency resources, and L data are received on L second time-frequency resources.
Assume that the identity of the first time-frequency resource is 1 and the identity of the second time-frequency resource is 2. As can be seen from fig. 8 and table 1, the first indication information may indicate the identities of 3 first time-frequency resources and the identities of 3 second time-frequency resources, i.e. 1, 2.
For example, the first arrival time of the data is 0ms, the first starting time is 0ms, the 1 st data is transmitted using the first time-frequency resource, so 3 times of data are continuously transmitted, namely, the 1 st, 2 nd and 3 rd data are transmitted using the first time-frequency resource, the arrival time of the 4 th data is 2.5ms, and after the 2ms of the 3 rd data are transmitted, the 2.5ms is the first time for transmitting the data, so 3 times of data are transmitted on the second time-frequency resource, namely, the 4 th, 5 th and 6 th data are transmitted using the second time-frequency resource. And so on to transmit data.
In a second possible implementation, the first time-frequency resource for transmitting or receiving data may be autonomously determined before the network device or the terminal device transmits or receives the data.

The ith moment is the starting moment of the ith-1 service period of the data, the jth moment is the starting moment of the first time frequency resource of the ith-1 transmission data, the jth moment is the starting moment of the first time frequency resource of the ith transmission data, and both the i and the j are positive integers.
In one possible design, each first time-frequency resource may be detected to determine the first time-frequency resource that may transmit data. In some embodiments, the network device may first determine a first value from the i-1 th time and the j-1 th time, the first value being a difference between the j-1 th time and the i-1 th time, or the first value being an absolute value of a difference between the j-1 th time and the i-1 th time. And then, determining n as a positive integer according to the first period, the first numerical value and the second period, wherein n is the number of the first period, the number of the first period meets the minimum value of the first condition, and the first condition is that the sum of the first period and the first numerical value is larger than the second period. And determining the sum of the n first periods and the first value as the j time. The j-th time satisfies the formula (2).

Wherein T is j Represents the j-th time, c 1 Represents a first period, n represents the number of the first periods, t i-1 Represents the i-1 th time, T i-1 Indicating time i-1, c 2 Representing a second period.
In another possible design, the network device may determine the time of the first time-frequency resource for transmitting data based on the start time of the service period (or the arrival time of the service).
In some embodiments, the network device may determine n as a positive integer according to a j-1 th time, a first period, and an i-1 th time, where n is the number of first periods, the number of first periods satisfies a minimum value of a first condition, the first condition is that a sum of the first periods and the j-1 th time is greater than the i-1 th time, the i-1 th time is a start time of an i-th service period of the data, and a sum of the i-1 th time and the second period is equal to the i-th time. And then, determining the j moment according to the n first periods and the j-1 moment, wherein the j moment is the minimum value in the starting moment of the first time-frequency resource which is larger than the i moment.
The j-th time satisfies the formula (3).
T j ＝T j-1 +n*c 1 ＞t i (3)
Wherein T is j Represents the j-th time, c 1 Represents a first period, n represents the number of the first periods, t i Represents the i-th time, T j-1 Indicating the j-1 time.

S905, the terminal equipment determines a j moment according to the first period, the second period, the i-1 moment and the j-1 moment.
In one possible design, each first time-frequency resource may be detected to determine the first time-frequency resource that may transmit data. In another possible design, the network device may determine the time of the first time-frequency resource for transmitting data based on the start time of the service period (or the arrival time of the service). Specific reference to S903 is not repeated.

Therefore, the terminal equipment receives the data on the determined first time-frequency resource, and the first time-frequency resource which does not receive the data can receive other information, so that the utilization rate of the configuration resource is effectively improved. Meanwhile, blind detection of all configured first time-frequency resources is avoided, blind detection of determined first time-frequency resources is performed, and power consumption of terminal equipment is saved.
In other embodiments, before the terminal device sends the data to the network device, the first time-frequency resource for sending the data may be determined first, where the data may be uplink data, and the first time-frequency resource may be PUSCH. S907 and S910 are performed.

Specific explanation of S907 and S910 may refer to the explanation of S903 and S906, which will not be repeated.
In addition, if there is a deviation between the start time of the 1 st service period of the data and the start time of the first time-frequency resource of the 1 st transmission data, there may be an error in the transmission data, and the receiving end may not accurately receive the data.
