Description

A method and device for resource indication

Technical field

Embodiments of the present application relate to the field of wireless communications, and in particular, to a method and device for resource indication.

Background technique

With the development of mobile communication technology, the fifth generation (5G) mobile communication technology has become a hot spot of global research and development. As the main driving force for future communication development, mobile Internet and Internet of Things will have a huge impact on people's living, work, leisure, transportation and other fields, and 5G business needs are diversified. For example, in industrial control scenarios, the controller needs to maintain time synchronization with the actuators. The controller sends control signaling to the actuator, instructing the actuator to execute the command at a certain time. If the actuator and the controller have different perceptions of time, that is, the time is not synchronized, it will cause the actuator to execute the command at the wrong time, resulting in Task execution failed. As a centralized controller of terminal equipment, network equipment can be used as a time synchronization source for terminal equipment, sending instruction information to terminal equipment, so that all terminal equipment in the community can maintain time synchronization with network equipment, and indirectly achieve the time between terminal equipment. Synchronize.

Network devices and terminal devices can periodically exchange time information (such as time-sensitive networking (TSN) information), and adjust clocks based on the time information to maintain time synchronization. For example, TSN information is transmitted on configured resources (such as configured grant (CG) resources or semi-persistent scheduling (SPS) resources). However, since the service cycle (such as the cycle of TSN information) is different from the cycle of configured resources, after the service arrives, if the time of arrival of the service is different from the time of sending the configured resources, the TSN information will be sent after the time of sending the configured resources. In some embodiments, as shown in (a) in Figure 1, the cycle of configuring resources is greater than the service cycle, and the delay in transmitting time information is larger; as shown in (b) in Figure 1, if the cycle of configuring resources is If it is less than the business cycle, some configuration resources (the resources corresponding to the time when "×" is drawn in the figure) will not transmit the business cycle, which is a waste of configuration resources. Therefore, how to improve the utilization of system resources is an urgent problem to be solved.

In the embodiments of this application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "such as" in the embodiments of the present application is not to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the words "exemplary" or "such as" is intended to present the concept in a concrete manner.

Mobile communication technology has profoundly changed people's lives, but people's pursuit of higher-performance mobile communication technology has never stopped. In order to cope with the explosive growth of mobile data traffic in the future, massive mobile communication device connections, and the continuous emergence of various new services and application scenarios, the 5G mobile communication system emerged as the times require. The 5G mobile communication system is also called the new radio access technology (NR) system. The International Telecommunication Union (ITU) has defined three major application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), URLLC, and massive machine type communications (mMTC). , Multimedia Broadcast Multicast Service (Multimedia BroadcastMulticast Service, MBMS) and positioning services, etc. Deployment scenarios include indoor hotspots, dense urban areas, suburbs, urban macro coverage, and high-speed rail scenarios.

Typical eMBB services include ultra-high definition video, augmented reality (AR) and virtual reality (VR), etc. The main characteristics of these services include large amounts of transmitted data and high transmission rates.

Typical mMTC services include smart grid distribution automation and smart cities. The main characteristics of these services include the huge number of networked devices, the small amount of transmitted data, and the data being insensitive to transmission delays. These mMTC terminals need to meet the requirements of low cost and very long standby time.

Typical URLLC businesses include wireless control in industrial manufacturing or production processes, motion control of driverless cars and drones, and tactile interactive applications such as remote repair and remote surgery. The main characteristics of these services are the requirement of ultra-high reliability, low latency, small amount of transmitted data and burstiness. For example, vehicle to everything (V2X) information exchange with the outside world requires a reliability of 99.999% and an end-to-end delay of 5 milliseconds (milliseconds); power distribution requires a reliability of 99.9999%. The end-to-end delay is 5ms; the factory automation reliability is 99.9999%, and the end-to-end delay is 2ms.

In the long term evolution (LTE) system, the smallest time scheduling unit is a transmission time interval (TTI) with a length of 1ms. 5G supports not only time domain scheduling granularity at the time unit level, but also time domain scheduling granularity at the micro time unit level, and can meet the delay requirements of different services. For example, time units are mainly used for eMBB services, and micro time units are mainly used for URLLC services. It should be noted that the above time unit and micro time unit are general terms. A specific example can be that the time unit can be called a time slot, and the micro time unit can be called a micro time slot or non-slot. -based), mini-slot or symbol; alternatively, the time unit can be called a subframe, and the micro time unit can be called a micro subframe; other similar time domain resource division methods are not limited. .

The number of time domain symbols included in a mini-slot is less than 7, such as 2 or 4, etc. The specific value is not limited.

For example, the first indication information may be a bitmap, and the bitmap may include N bits. If M bits among the N bits are 1, it can mean that each first time-frequency resource among the first time-frequency resources indicated by the M bits is used to transmit data, and N-M among the N bits The bits of the bits are 0, which may indicate that each first time-frequency resource among the first time-frequency resources indicated by the N-M bits is not used to transmit data. If M bits among the N bits are 0, it can mean that each first time-frequency resource among the first time-frequency resources indicated by the M bits is used to transmit data, and N-M among the N bits The bits of bits are 1, which may indicate that each first time-frequency resource among the first time-frequency resources indicated by the N-M bits is not used to transmit data.

In some embodiments, when the network device sends data to the terminal device, the data may be sent on the 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, for a detailed explanation of the data sent by the network device to the terminal device, refer to the description of S403 and S404.

S403. The network device sends data to the terminal device on M first time-frequency resources among the N first time-frequency resources with the N first time-frequency resources as a period.

It should be particularly emphasized that in this application, the data sent to the terminal device on the M first time-frequency resources among the N first time-frequency resources may be M pieces of data. Each of the M pieces of data may be a data transmission block (TB), or a group of data transmission blocks, and the group of data transmission blocks may be multiple repetitions of one transmission block, It can also be multiple transmission blocks, which will not be described again later.

In some embodiments, starting from the first starting moment, N first time-frequency resources are used as resource cycle periods, and data is sent on M first time-frequency resources in each resource cycle period.

In some embodiments, the terminal device may determine the time to send the first time-frequency resource based on the first starting time and the first period.

S406: The network device receives the data sent by the terminal device on M first time-frequency resources among the N first time-frequency resources with the N first time-frequency resources as a period.

In some embodiments, starting from the first starting moment, N first time-frequency resources are used as resource cycle periods, and M pieces of data are received on M first time-frequency resources in each resource cycle period.

The resource indication method provided by the embodiment of the present application enables the network device and the terminal device to receive or send data on the designated first time-frequency resource by indicating the first time-frequency resource for sending data, thereby effectively improving the configuration Resource utilization.

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 configured first time-frequency resources, some of the first time-frequency resources do not carry data, which will result in wasted power consumption of the receiving end. Embodiments of the present application provide a resource indication method. The receiving end performs blind detection on the first time-frequency resource indicated by the first indication information to receive data. This avoids blind detection of all configured first time-frequency resources, which not only effectively improves The utilization of time-frequency resources also saves power consumption at the receiving end. The embodiments of this application provide a method for determining resource allocation. On the premise of meeting the data transmission delay, the minimum resource cycle period and the minimum number of resource usage are selected, thereby reducing the overhead of indication information and improving system resource utilization. . Moreover, the method provided by the embodiments of this application can better match the service and resource cycles, avoid deviations in the understanding of available resources by the receiving end and the sending end, and thereby ensure the delay and reliability of the service.

In some embodiments, N and M may be determined by the network device based on the first starting time, the first period, the second starting time, and the second period. The second starting time is the starting time of the data service cycle. The second cycle is the business cycle of data. After the service arrives, if the time when the service arrives is different from the time when the first time-frequency resource is sent, the data will be sent after waiting until the time when the first time-frequency resource is sent. In order to ensure the delay in sending data and avoid the situation where a certain service has not been sent yet and the next service has arrived, the first period should be set to be smaller than the second period. As shown in Figure 5, before sending the first instruction information, that is, S401, S501 is executed.

S501. The network device determines M first time-frequency resources among the number N of first time-frequency resources based on the first starting time, the first period, the second starting time, and the second period.

Since the time when the service arrives and the time when the first time-frequency resource is sent appear periodically, the difference between the time when the service arrives and the time when the first time-frequency resource is sent also exhibits a periodic pattern. In some embodiments, the network device may determine specific values of N and M based on the first period and the second period. N and M satisfy the following formula (1).

P_tr*M＝P_re*N (1)

Among them, P_tr represents the second period, and P_re represents the first period.

Further, after the network device determines the specific values of N and M, it determines M first time-frequency resources among the N first time-frequency resources for transmitting data. Assume that the second starting time is the starting time of the data service cycle, and 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-frequency resource is sent for the first time. The first time-frequency resource corresponding to the first starting time may be determined as the first time-frequency resource for transmitting data, and then the first time-frequency resource corresponding to the time of the first time-frequency resource closest to the time of service arrival may be determined as The first time-frequency resource for transmitting data, and so on, thereby determining M first time-frequency resources among the N first time-frequency resources.

Optionally, the second cycle can be configured in advance for the network device and the terminal device. Therefore, the network device does not need to obtain the second cycle from other network elements. Or obtain the second cycle before transmitting data through information interaction between the terminal device and the network device.

Taking the second period as 0.833 ms as an example, the following describes the determination of M first time-frequency resources among the number N of first time-frequency resources. In order to ensure the delay of sending data, a suitable first time-frequency resource is searched for among the first time-frequency resources that are less than 0.833ms. For example, for a time 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. Therefore, the time length of the first period is Values can be 0.5ms or 1/7ms.

When the first period is 0.5ms and the second period is 0.833ms, substitute 0.5ms and 0.833ms into formula (1), that is, P_re=0.5ms=1/2ms, P_tr=0.833ms=5/6ms, select 5 /6*M=1/2*N holds the smallest M and N, then M=3 and N=5. M and N satisfy the mutually prime relationship.

When the first period is 1/7ms and the second period is 0.833ms, substitute 1/7ms and 0.833ms into formula (1), that is, P_re=1/7ms, P_tr=0.833ms=5/6ms, select 5/ 6*M=1/7*N holds the minimum M and N, then M=6, N=35. M and N satisfy the mutually prime relationship.

Therefore, on the premise of ensuring the data transmission delay, select M and N with the shortest resource cycle period, or further consider M and N with the smallest number of resources configured in the resource cycle period, then it can be determined that M=3, N=5, and One cycle is 0.5ms. As shown in Figure 6, a schematic diagram of sending data. The time at which the first time-frequency resource is sent may be 0, 0.5, 1, 1.5, 2, 2.5, etc. No data will be transmitted on the first time domain resource corresponding to the time when "×" is drawn in the figure.

As shown in Table 1, it is the specific time of sending data.

Table 1

Business serial number Business arrival (ms) The time when the first time domain resource is sent (ms) 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

It can be seen from Figure 6 and Table 1 that the service sequence number 0 represents the first data arrival, the arrival time of the first data arrival is 0ms, the time when the first time domain resource is sent is 0ms, and the time when data is sent for the first time is 0ms. Service number 1 indicates the second data arrival. The arrival time of the second data arrival is 0.833333ms. The time when the first time domain resource is sent is 1ms. The second time when data is transmitted is 1ms. The delay is 0.166667. Service number 2 indicates the third data arrival. The arrival time of the third data arrival is 1.666667ms, the time of sending the first time domain resource is 2ms, and the time of the third data transmission is 2ms. The delay is 0.333333. No data is sent on the first time-frequency resource corresponding to 0.5ms and the first time-frequency resource of 1.5ms, and the cycle is repeated.

Therefore, every five first time-frequency resources is one resource cycle period. For each resource cycle period, data is sent or received on the first first time-frequency resource, the third first time-frequency resource and the fifth first time-frequency resource, and the second first time-frequency resource and the fifth first time-frequency resource are sent or received. No data is sent on the four first time-frequency resources.

Therefore, 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.

For example, assuming that the second period is 16.67ms=100/6ms, select a value where the first period is smaller than the second period, such as 5ms, 8ms or 10ms. According to formula (1), M and N can be obtained as shown in Table 2 value. Finally, it can be determined to select the smallest combination M=3, N=5

Table 2

first cycle M N 10 3 5 8 12 25 5 3 10

Therefore, on the premise of ensuring the data transmission delay, select M and N with the shortest resource cycle period, or further consider M and N with the smallest number of resources configured in the resource cycle period, then it can be determined that M=3, N=5, and One cycle is 10ms. The first indication information may indicate 3 first time-frequency resources among the 5 first time-frequency resources. Every five first time-frequency resources is a resource cycle. For each resource cycle period, data is sent or received on the second first time-frequency resource, the fourth first time-frequency resource, and the fifth first time-frequency resource, and the first first time-frequency resource and the fifth first time-frequency resource are No data is sent on the three first time-frequency resources. If the first indication information is a bitmap, the bitmap is 01011. Or the first information also indicates that the value of N is 5.

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 Figure 5, before S501, S502 to S503 are executed.

S502. The network device sends the first resource configuration information to the terminal device.

In some embodiments, the network device may send the first resource configuration information to the terminal device through high-layer signaling. For example, the network device may send the first resource configuration information to the terminal device through RRC signaling.

The first resource configuration information is rrc-ConfiguredUplinkGrant. The first resource configuration information includes a first starting time and a first period.

S503. The terminal device receives the first resource configuration information sent by the network device.

The second resource configuration information includes a third starting time and a third period. The third starting time is the starting time for sending the second time-frequency resource, and the third period is the period for sending the second time-frequency resource.

Receive data. The second resource configuration information includes a third starting time and a third period. For a specific explanation of the second resource configuration information, please refer to the explanation of S701, and there is no need to repeat it.

It should be noted that the sequence of steps in the resource indication method provided by the embodiments of the present application can be adjusted appropriately.

Anyone familiar with the technical field can Within the technical scope disclosed in this application, it is easy to think of various methods of change, which are all covered by the protection scope of this application, and therefore will not be described again.

In some embodiments, the network device may also determine L second time-frequency resources among the number K of second time-frequency resources, that is, determine the resource cycle period of the second time-frequency resources. As shown in Figure 7, before sending the first instruction information, that is, S401, S703 is executed.

S703. The network device determines L second time-frequency resources among the number K of second time-frequency resources based on the third starting time, the third period, the second starting time, and the second period.

Since the time when the service arrives and the time when the second time-frequency resource is sent appear periodically, the difference between the time when the service arrives and the time when the second time-frequency resource is sent also exhibits a periodic pattern. In some embodiments, the network device may determine K and L based on the third starting moment, the third period, the second starting moment and the second period, where K and L are both positive integers, and K and L satisfy the formula ( 1). For details, please refer to the explanation of S501 and will not be repeated.

Therefore, the first indication is also used to indicate L second time-frequency resources among 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 the 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.

There may be one or more data sent on the second time-frequency resource, and each data in the plurality of data may be the same or different, and there is no limitation.

S705: The terminal device receives the data sent by the network device on L second time-frequency resources among the K second time-frequency resources with the K second time-frequency resources as a period.

In some embodiments, the terminal device may determine the time to send the second time-frequency resource based on the third starting time and the third period. After the terminal device receives the first indication information, starting from the third starting time, taking K second time-frequency resources as the resource cycle period, it receives M on the L second time-frequency resources in each resource cycle period. data. The data received on the second time-frequency resource may be one or more, and each data in the multiple data may be the same or different, without limitation.

M bits among the N bits indicate the first time-frequency resource for transmitting or receiving data. L bits among the K bits indicate the second time-frequency resource for transmitting or receiving data. Or the value of N is also indicated in the first information.

It can be understood that M+L data represents the business cycle. In each service cycle, data (for example, M pieces of data) are received on M first time-frequency resources, and data (for example, L pieces of data) are received on L second time-frequency resources.

For example, as shown in Figure 8, a schematic diagram of sending data. The first starting time is 0ms, the first period is 1ms, and the time at which the first time-frequency resource is sent can be an integer millisecond, such as 0, 1, 2, 3, etc. The third starting time is 0.5ms, the third period is 1ms, and the time at which the second time-frequency resource is sent can be a half-integer millisecond, such as 0.5, 1.5, 2.5, etc. There is a difference of 0.5 ms between the time when the first time-frequency resource is sent and the time when the second time-frequency resource is sent.

The arrival time of the sixth data arrival is 4.166667ms, the time when the first time domain resource is sent is 4.5ms, and the sixth data transmission time is 4.5ms. The delay is 0.333333. No data is sent on the first time-frequency resource corresponding to 0.5ms and the first time-frequency resource of 1.5ms. Cycle in turn.

Therefore, every five first time-frequency resources is a first resource cycle period. For each first resource cycle, data is sent or received on the first first time-frequency resource, the second first time-frequency resource, the third first time-frequency resource, and the fourth first time-frequency resource. and no data is sent on the fifth first time-frequency resource. Every five second time-frequency resources is a second resource cycle period. For each second resource cycle period, data is sent or received on the third first time-frequency resource, the fourth first time-frequency resource, and the fifth first time-frequency resource, and the first first time-frequency resource and no data is sent on the second first time-frequency resource.

The bitmap is 1110000111. Or the first information also indicates that the value of N is 10.

In another possible design, the first indication information includes an identifier of a first time-frequency resource for transmitting M pieces of data and an identifier of a second time-frequency resource for transmitting L pieces of data.

It should be understood that "transmitting" may refer to sending or receiving. M+L data is the business cycle. In each service cycle, M pieces of data are received on M first time-frequency resources, and L pieces of data are received on L second time-frequency resources.

It is assumed that the identifier of the first time-frequency resource is 1 and the identifier of the second time-frequency resource is 2. As can be seen from Figure 8 and Table 1, the first indication information may indicate the identifiers of three first time-frequency resources and the identifiers of three second time-frequency resources, that is, 1, 1, 1, 2, 2, 2.

For example, the first arrival time of data is 0ms, the first starting time is 0ms, and the first time-frequency resource is used to transmit the first data. Therefore, data is transmitted three times in a row, that is, the first, second, and third data are transmitted. Using the first time-frequency resource, the arrival time of the fourth data is 2.5ms. After 2ms of transmitting the third data, 2.5ms is the first opportunity to transmit data. Therefore, 3 is sent on the second time-frequency resource. Second time data, that is, the second time-frequency resource is used to transmit the 4th, 5th and 6th data. The data is transmitted in turn.
