The chip system in the embodiments of the present application may be composed of chips, and may also include chips and other discrete devices.

2) The network equipment includes a base station (BS), which may be a device that can be deployed in a wireless access network and can perform wireless communication with a terminal. Among them, the base station may have multiple forms, such as macro base stations, micro base stations, relay stations, and access points. Exemplarily, the base station involved in the embodiments of the present application may be a base station in a 5th generation (5G) mobile communication system or a base station in long term evolution (LTE), where the base station in 5G also It can be called a transmission and reception point (TRP) or gNB. In the embodiment of the present application, the device that realizes the function of the network device may be a network device, or may be an device that supports the function of the network device, for example, a chip system.

3) Communication system, you can use various wireless access technologies (radio access technology, RAT), such as code division multiple access (code division multiple access (CDMA), time division multiple access (time division multiple access, TDMA), frequency division multiple Frequency (division multiple access, FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (single carrier FDMA, SC-FDMA), etc. The RAT used is not limited. In this application, the term "system" may be interchanged with "network". The network can be divided into 2G (generation) network, 3G network, 4G network or future evolution network, such as 5G network, according to factors such as the capacity, rate, delay, and RAT adopted by different networks. A typical 2G network includes a global mobile communication system (global system for communication / general packet radio service, GSM) network or a general packet radio service (general packet radio service, GPRS) network, and a typical 3G network includes a universal mobile communication system (universal Mobile telecommunications systems (UMTS) networks.

For example, unlicensed spectrum resources may include the 5GHz frequency band. Among them, using unlicensed spectrum resources to transmit data, the sender can follow the principle of listen before talk (LBT), that is, before sending data using the unlicensed channel corresponding to the unlicensed spectrum resources, the sender needs to The channel is monitored.

It is understandable that in the description of this application, the words “first” and “second” are only used to distinguish the description, and cannot be understood as indicating or implying relative importance, nor as indicating or implying order. In the embodiments of the present application, the term “wireless communication” may also be simply referred to as “communication”, and the term “communication” may also be described as “data transmission”, “information transmission”, or “transmission”.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

As shown in FIG. 1, an embodiment of the present application provides a communication system 100. The communication system 100 may include a network device 101 and a terminal device 102.

Among them, the network device 101 and the terminal device 102 can communicate through the licensed spectrum, can also communicate through the unlicensed spectrum, and can also communicate through the licensed spectrum and the unlicensed spectrum at the same time. The embodiments of the present application do not limit the spectrum resources used between the network device and the terminal device.

As an example, when the network device 101 and the terminal device 102 communicate on the licensed spectrum, they can communicate according to the fixed first uplink-downlink ratio. For example, in the industrial Internet, it has the characteristics of considerable uplink and downlink traffic. Therefore, the first uplink and downlink ratio can be set to 1: 1, and the network device 101 and the terminal device 102 can follow the fixed 1: 1 first level Line matching and communication. For this example, the terminal device 102 needs to obtain permission from the network device 101 before sending the uplink data, that is, the terminal device 102 can send the uplink data only after the permission from the network device 101, and the delay of the uplink data is large. Exemplarily, first, the terminal device 102 sends an uplink request to the network device 101. After receiving the uplink request, the network device 101 may send an uplink sending permission to the terminal device 102. After receiving the uplink sending permission, the terminal device 102 Before sending uplink data.

As another example, when the network device 101 and the terminal device 102 communicate on an unlicensed spectrum, the principle of listen before talk (LBT) can be followed. When the network device 101 or the terminal device 102 sends data, they need to first Monitor the channel and only send data when the channel is idle. For this example, both the network device 101 and the terminal device 102 need to monitor the channel when sending data, and data can be sent only when the channel is detected to be idle, and the transmission delay of both uplink data and downlink data is large.

In view of the above, the present application provides a communication method. The principle of the communication method is as follows: a terminal device sends downlink service data on authorized spectrum resources, and sends uplink service data on unlicensed spectrum resources. Since uplink service data is sent on unlicensed spectrum resources without the permission of network equipment, the transmission delay of uplink service data can be reduced. Further, the network device can allocate the first time-frequency resource to the terminal device on the unlicensed spectrum resource, and the terminal device can directly perform uplink data transmission on the first time-frequency resource, without following the LBT principle, and further reducing upstream service data Transmission delay.

As shown in FIG. 2, taking the device that realizes the function of the network device as a network device, and taking the device that realizes the function of the terminal device as a terminal device as an example, a process of a communication method is provided. In the network device 101 shown in FIG. 1, the terminal device may be the terminal device 102 shown in FIG. 1 described above. The process includes:

S201. The network device sends downlink service data on the authorized spectrum resource.

S202. The terminal device receives downlink service data on the authorized spectrum resource.

S203. The terminal device sends uplink service data on unlicensed spectrum resources.

The uplink service data includes at least one of normal uplink service data or burst uplink service data, and the normal uplink service data may also be called normal uplink service data. The method can also be described as: the uplink service data includes at least one of normal uplink service data or burst uplink service data. For example, the uplink service data includes ordinary uplink service data, the uplink service data includes burst uplink service data, or the uplink service data includes normal uplink service data and burst uplink service data.

S204. The network device receives uplink service data on unlicensed spectrum resources.

In the frequency domain, when the authorized spectrum resource is configured to be used only for downlink data transmission, the unlicensed spectrum resource can be used for burst uplink service data transmission and ordinary uplink service data transmission, that is, the terminal device is in the unlicensed spectrum Burst uplink service data and normal uplink service data can be sent on resources. Correspondingly, network equipment can receive burst uplink service data and normal uplink service data on unlicensed spectrum resources. In an implementation manner, when burst uplink service data and normal uplink service data are to be sent on the unlicensed spectrum resource at the same time, the terminal device may send the burst uplink service data first, and then send the normal uplink service data. Alternatively, the terminal device may perform puncturing on the unlicensed spectrum, the punctured position is used to send ordinary uplink service data, and the non-punctured position may be located to send burst uplink service data. When the authorized spectrum resource is configured to be used for both uplink data transmission and downlink data transmission, the unlicensed spectrum resource can be used for burst uplink service transmission, that is, the terminal device can send burst uplink service data on the unlicensed spectrum resource Correspondingly, the network equipment can receive burst uplink service data on unlicensed spectrum resources.

Optionally, in the embodiment of the present application, when the authorized spectrum resource is configured to be used for both uplink data transmission and downlink data transmission, if the first uplink and downlink ratio in the authorized spectrum resource is not met, the timely transmission of uplink services cannot be satisfied. According to data requirements, the terminal device can also send uplink service data on unlicensed spectrum resources. Correspondingly, the network device can also receive uplink service data on unlicensed spectrum resources. For example, as shown in Figure 5, authorized spectrum resources are 3.5GHz-3.7GHz and unlicensed spectrum resources are 5GHz. Network equipment and terminal equipment can perform uplink service transmission and downlink service transmission on the authorized spectrum resources. Network equipment and terminal equipment Only uplink service transmission is performed on unlicensed spectrum resources.

In the embodiment of the present application, the network device may allocate the first time-frequency resource to the terminal device in the unlicensed spectrum resource. Wherein, in the frequency domain, the first time-frequency resource includes a first resource block on an unlicensed spectrum resource. The first resource block may specifically include one or more resource blocks. In the time domain, the first time resource The frequency resource includes the first time unit. The network device may send a first indication, which is used to notify the terminal device of the first time-frequency resource. Correspondingly, the terminal device may receive the first indication, and according to the first indicated by the first indication Time-frequency resources to send upstream service data to network equipment. Alternatively, the position of the first time-frequency resource in the unlicensed spectrum can be pre-configured or pre-defined. When the terminal device has uplink service data to be sent, the first time-frequency resource at the corresponding position on the unlicensed spectrum resource is directly used to send the uplink service The data is sufficient.

In practical applications, the service range of the network device may include one or more terminal devices. When a terminal device is included in the service range of the network device, the network device may allocate the first time-frequency resource to the terminal device independently. When the service range of the network device includes multiple terminal devices, the network device may allocate an independent or non-independent first time-frequency resource to each terminal device on the unlicensed spectrum resource, where the corresponding The time-frequency resources may overlap completely or partially, or may not overlap at all. It can be understood that the first time-frequency resources can be independently allocated to each terminal device, for example, non-overlapping first time-frequency resources can be allocated, or the first time-frequency resources that partially overlap can be allocated, which can reduce different terminals as much as possible. The overlap probability of the first time-frequency resource between devices. The size of the first time-frequency resource corresponding to each terminal device may be the same or different.

In the embodiments of the present application, the following manner may be used to allocate the first time-frequency resource to the terminal device:

The network device may send the first information to the terminal device on the authorized spectrum resource, for example, the first information may be carried in information such as uplink scheduling information or resource configuration information of the authorized spectrum resource. The first information includes resource configuration information of authorized spectrum resources. For example, the resource configuration information of the authorized spectrum resource may include a time slot format, positions of channels and signals in the time slot, subcarrier spacing, cyclic prefix (CP) length, and so on.

The terminal device may receive the first information from the network device on the authorized spectrum resource, and according to the resource configuration information of the authorized spectrum resource in the first information, etc., send the second information to the network device at the corresponding position of the authorized spectrum resource. The second information includes feedback for the first information. Specifically, the second information may be a confirmation signal, confirmation information, or confirmation feedback.

After receiving the second information, the network device may determine the number of terminal devices within its service range. Then, according to factors such as the number of terminal devices and the service volume, each terminal device within its service range is allocated the first time-frequency resource on the unlicensed spectrum resource.

In the following embodiments, the first time-frequency resource that does not overlap with each other is allocated to each terminal device on unlicensed spectrum resources, and the size of the first time-frequency resource corresponding to each terminal device is the same as an example. :

For example, as shown in FIG. 3, the number of terminal devices within the service range of the network device is 9, and the serial numbers are terminal device 0 to terminal device 8 in sequence. Then, in the frequency domain, the network device may divide the current unlicensed spectrum resource into 9 blocks, with the sequence numbers being resource block 0 to resource block 8 in sequence. In the time domain, within a cyclic time (CT), the network device can divide the time into three parts, namely {0, 1 / 3CT} time, {1 / 3CT, 2 / 3CT} time and { 2 / 3CT, CT} time. The network device may allocate first time-frequency resources to terminal device 0 to terminal device 8 respectively.

In an example, referring still to FIG. 3, the first time-frequency resource corresponding to terminal device 0 is: the frequency domain includes resource blocks (0, 3, 6), and the time domain includes {0, 1 / 3CT} Time; the first time-frequency resource corresponding to terminal device 1 is: resource blocks (0, 3, 6) in the frequency domain, and {1 / 3CT, 2 / 3CT} time in the time domain; the corresponding terminal device 2 The first time-frequency resource includes: resource blocks (0, 3, 6) in the frequency domain, and includes {2 / 3CT, CT} time in the time domain; the first time-frequency resource corresponding to the terminal device 3 is: frequency domain Includes resource blocks (1, 4, 7), and time domain includes {0, 1 / 3CT} time; the first time-frequency resource corresponding to terminal device 4 is: resource blocks (1, 4, 7) in frequency domain ), The time domain includes {1 / 3CT, 2 / 3CT} time; the first time-frequency resource corresponding to the terminal device 5 is: the frequency domain includes resource blocks (1, 4, 7), and the time domain includes {2 / 3CT, CT} time; the first time-frequency resource corresponding to terminal device 6 is: resource blocks (2, 5, 8) in the frequency domain, and {0, 1 / 3CT} time in the time domain, terminal device 7 The corresponding first time-frequency resources are: resource blocks (2, 5, 8) in the frequency domain, {1 / 3CT, 2 / 3CT} time in the time domain, and the first time-frequency resources corresponding to the terminal device 8 It includes: resource blocks (2, 5, 8) in the frequency domain, and {2 / 3CT, CT} time in the time-frequency.

If at terminal 1 / 4CT, terminal device 3, terminal device 7, and terminal device 8 have upstream service data to be sent, then terminal device 3 can directly use resource blocks (1, 4 at {1 / 4CT, 1 / 3CT} time 7) To send upstream service data, the terminal device 7 can directly use the resource blocks (2, 5, 8) to send upstream service data at the time of {1 / 3CT, 2 / 3CT}, and the terminal device 8 can directly send the data at {2 / 3CT, CT} Time resource blocks (2, 5, 8) are used to send upstream service data, and there is no need to follow the LBT principle. It can be seen that in the embodiment of the present application, when the terminal device sends uplink service data on unlicensed spectrum resources, it does not need to go through processes such as uplink request and uplink permission when sending uplink service data on authorized spectrum resources, thereby reducing uplink Data transmission delay. It can be understood that, in the foregoing embodiment, the first time-frequency resource of the same size allocated by the network device to each terminal device is used as an example for description, and is not intended to limit the embodiment of the present application. The network device may allocate the same first time-frequency resource to different terminal devices, or different first time-frequency resources. For example, if some terminal devices have large uplink traffic, then the network device may allocate a large first time-frequency resource to the terminal device, and if some terminal devices have small uplink traffic, then the network device may be the terminal device Assign smaller first time-frequency resources, etc.

It should be noted that, in the embodiment of the present application, the network device may statically, semi-statically, or dynamically allocate the first time-frequency resource to the terminal device. The static means that after the network device is initialized, the first time-frequency resource is indicated to the terminal device, and the subsequent terminal device can use the first time-frequency resource to send uplink service data to the network device. The semi-static and dynamic means that the network device can adjust the first time-frequency resource allocated to the terminal device in real time according to factors such as the change in the uplink traffic volume and the quantity change of the terminal device, and the adjusted first time-frequency resource can be timely Notify the terminal device. For example, in the current communication process, a new terminal device appears in the service range of the network device, then the network device needs to allocate the first time-frequency resource to the terminal device, and may need to adjust the original first time-frequency resource of other terminal devices The network device needs to notify the corresponding terminal device of the first time-frequency resource allocated for the new terminal device and the original adjusted first time-frequency resource of other terminal devices. As another example, in the current communication process, the service volume of the terminal device changes, then the network device can adjust the first time-frequency resource allocated to the terminal device according to the change in the service volume of the terminal device, and the adjusted first time Notify the corresponding terminal equipment of the frequency resource.

When the network device semi-statically allocates the first time-frequency resource to the terminal device, the first time-frequency resource may be allocated to the terminal device through semi-static signaling. For example, the semi-static signaling may be radio resource control (radio resource control (RRC) signaling, broadcast message, system message, medium access control (MAC) control element (control element), CE, etc.

When the network device dynamically allocates the first time-frequency resource to the terminal device, the first time-frequency resource may be allocated to the terminal device through dynamic signaling. For example, the dynamic signaling may be physical layer signaling, and the physical layer signaling may be signaling carried by downlink control information (downlink control information, DCI) or physical downlink shared channel (physical downlink shared channel, PDSCH). The DCI may be signaling sent by the network device to the terminal device through a physical downlink control channel (PDCCH), that is, the DCI may be signaling carried by the PDCCH.

Optionally, in the embodiment of the present application, the network device may also determine whether the currently configured unlicensed spectrum resource is available, etc., specifically:

The network device sends third information to the terminal device on the authorized spectrum resource, and the third information may be carried in information such as uplink scheduling information or resource configuration information of the unlicensed spectrum resource. The third information includes resource configuration information of unlicensed spectrum resources. For example, the resource configuration information of unlicensed spectrum resources may include the location and bandwidth of unlicensed spectrum resources. Correspondingly, the terminal device receives the third information from the terminal device on the authorized spectrum resource. The third information may be carried in the same information as the above first information, or may be carried in different information.

The terminal device sends the fourth information to the network device at the corresponding position of the unlicensed spectrum resource according to the resource configuration information of the unlicensed spectrum resource in the third information, where the fourth information includes feedback for the third information. Correspondingly, the network device receives the fourth information from the terminal device at the corresponding position of the unlicensed spectrum resource.

After receiving the fourth information, the network device may determine whether the current unlicensed spectrum resource is available. If the currently licensed spectrum resource is available, the first time-frequency resource may be allocated to each terminal device in the unlicensed spectrum resource. If the currently licensed spectrum resource is not available, the unlicensed spectrum resource may be adjusted, and then the first time-frequency resource is allocated to each terminal device in the adjusted unlicensed spectrum resource.

For example, in the third information above, the unlicensed spectrum resource currently configured for the terminal device is 5.1GHz-5.2GHz, and if it is determined that the current unlicensed spectrum resource is unavailable, the unlicensed spectrum resource configured for the terminal device may be adjusted, The unlicensed spectrum resource afterwards may be 5.3GHz-5.4GHz and so on.

In the embodiments of the present application, the following method may be specifically adopted to determine whether the current unlicensed spectrum resource is available:

First example: M1 terminal devices are included in the service range of the network device, but M2 fourth information is received on the current unlicensed spectrum resource. When the ratio of (M1-M2) / M1 is less than or equal to the first threshold, the It is determined that the current unlicensed spectrum resource is available, otherwise it is determined that the current unlicensed spectrum resource is unavailable, but the first threshold may be, but not limited to, equal to 0, etc. For example, the service range of the network device includes 10 terminal devices, and the fourth information sent by the 10 terminal devices is received on the current unlicensed spectrum resource. Can it be determined that the current unlicensed spectrum resource is available. If the fourth information sent by the eight terminal devices is received on the current unlicensed spectrum resource, it may be determined that the current unlicensed spectrum resource is not available.

Second example: For each terminal device within the service range of the network device, the third information is sent on the authorized spectrum resource. Correspondingly, the network device can receive the third information sent by each terminal device on the authorized spectrum resource. For terminal device i, the network device can determine whether the fourth information sent by terminal device i can be received on the current unlicensed spectrum resource. If it can be received, it can be determined that terminal device i can communicate normally on the current unlicensed spectrum resource. The terminal device i is any terminal device in the service range of the network device. If the ratio of terminal devices that can normally communicate on the current unlicensed spectrum resource reaches the second threshold, it can be determined that the current unlicensed spectrum resource is available, otherwise, It is determined that the current unlicensed spectrum resource is not available, and the second threshold may be, but not limited to, 100%. For example, the network device service range includes 10 terminal devices. If all 10 terminal devices can communicate normally on unlicensed spectrum resources, the network device may determine that the current unlicensed spectrum resources are available, otherwise, determine the current unlicensed spectrum resources unavailable.

In the embodiment of the present application, the first information and the third information are both carried in the uplink scheduling information, and the second information and the fourth information are both determination signals as an example for description:

In time unit n, the network device may send uplink scheduling information to the terminal device on the authorized spectrum resource, and the uplink scheduling information may include a time slot format, the location of the channel and signal in the time slot, subcarrier spacing, and cyclic prefix (cyclic prefix) prefix, CP) length, location and bandwidth of unlicensed spectrum resources, etc. The time-frequency format, the position of the channel and signal in the time slot, the subcarrier interval and the CP length, etc. may be resource configuration information of authorized spectrum resources, and the position and bandwidth of the unlicensed resources may be resources of unlicensed spectrum resources Configuration information.

In the time unit n + k, the terminal device can use the format configured in the uplink scheduling information on the authorized spectrum resource and the unlicensed spectrum resource to send an acknowledgement signal to the network device. At this time, when the terminal device sends an acknowledgment signal on the unlicensed spectrum resource, it needs to comply with the LBT principle. Among them, n and k are integers greater than or equal to 0.

If the network device can receive the above confirmation signal on the current unlicensed spectrum resource, on the one hand, the network device can determine that the terminal device can receive the uplink scheduling information on the authorized spectrum resource. On the other hand, the network device can determine whether the transmission of the terminal device within its service range on the current unlicensed spectrum resource has the effect of other interference. For example, for a certain terminal device, the network device may receive the confirmation signal sent by the terminal device on the authorized spectrum resource, but also receive the confirmation signal sent by the terminal device on the current unlicensed spectrum resource. The network device can adjust the currently configured unlicensed spectrum resources (such as from 5.1GHz-5.2GHz to 5.3GHz-5.4GHz, etc.), and re-send the uplink scheduling information to the terminal device until the network device successfully receives its service range The confirmation signal sent by all terminal equipment on unlicensed spectrum resources.

In the embodiment of the present application, when the network device and the terminal device perform data transmission on the authorized spectrum resource, a time division multiple access (time division duplexing, TDD) duplex mode may be used. Specifically, the network device and the terminal device may use the first uplink-downlink ratio to perform data transmission on the authorized spectrum resource. For example, the network device may send downlink service data on the authorized spectrum resource according to the first uplink-downlink ratio. , The terminal device receives downlink service data on the authorized spectrum resource according to the first uplink and downlink ratio. Alternatively, the terminal device may send the uplink service data on the authorized spectrum resource according to the first uplink-downlink ratio, and correspondingly, the network device may receive the uplink service data on the authorized spectrum resource according to the first uplink-downlink ratio. The first uplink-downlink ratio may not be 1: 1. For example, the first uplink-downlink ratio may be 0: 1. At this time, the authorized spectrum resources are completely used for downlink, and uplink services may be transmitted on unlicensed spectrum resources. The uplink services may include burst uplink service data. And ordinary uplink business data. As another example, the first uplink-downlink ratio may be 3: 1, that is, on a licensed spectrum resource, a ratio of an uplink time unit used for uplink data transmission to a downlink time unit used for downlink data transmission is 3: 1.

For example, in the Industrial Internet, network devices and terminal devices can transmit data in units of cycles. The network device can configure the length of the cycle for the terminal device. For example, the network device may configure the terminal device with one cycle including one or more cycle times (CT), each CT includes one or more time units, and each time unit may include one or more time slots. The first uplink-downlink ratio may specifically refer to a ratio of uplink time units used for uplink service transmission and downlink time units used for downlink service transmission in a CT. For example, as shown in FIG. 4, a CT includes a downlink time unit, an idle time unit, and an uplink time unit. Wherein, the downlink time unit is used for downlink service transmission, the uplink time unit is used for uplink service transmission, and the idle unit is not used for service transmission. If the number of downlink time units is 3, and the number of uplink time units is 1, then the first uplink-downlink ratio may be specifically 1: 3. It can be understood that each CT may or may not include an idle unit, and only includes an uplink time unit and a downlink time unit. In the embodiment shown in FIG. 4, the CT includes an idle time unit as an example for description, and is not intended to limit the embodiment of the present application.

In the embodiment of the present application, the network device may adjust the first uplink-downlink ratio in the licensed spectrum in real time according to factors such as uplink and downlink traffic. For example, if the downlink traffic volume is large, the first uplink-downlink ratio in the licensed spectrum may be set smaller, or even set to 0: 1. At this time, the licensed spectrum is completely used for downlink data transmission. Compared with the prior art, the first uplink-downlink ratio in the licensed spectrum is fixed at 1: 1, which increases the flexibility of data transmission and meets the needs of uplink-downlink data transmission. It can be understood that after the network device determines the first uplink-downlink ratio in the authorized spectrum, the first uplink-downlink ratio can be notified to the terminal device through indication information, such as a second indication, so that the terminal device follows the The first uplink and downlink ratio receives downlink service data or sends uplink service data. Correspondingly, the network device may send downlink service data according to the first uplink and downlink ratio or receive uplink service data.

It can be seen from the above that in the embodiment of the present application, a way for the terminal device to send uplink service data in unlicensed spectrum resources is added, and the ratio of the uplink and downlink in the authorized spectrum resources can be flexibly configured to better balance the downlink The amount of data that needs to be sent and the real-time nature of uplink data sending.
