Description

Method and device for transmitting data

Technical Field

The present embodiments relate to the field of communications, and in particular, to a method and an apparatus for transmitting data in the field of communications.

Background

In an existing network system, a terminal device generally transmits uplink data by requesting a transmission resource to a network device, which is also referred to as grant-based transmission or grant-based transmission, for example, first, the terminal device sends a service request message to the network device to request the network device for a service to be sent; secondly, when the network equipment receives a service request message sent by the terminal equipment, the network equipment allocates transmission resources for transmitting uplink data to the terminal equipment according to the data cache state reported periodically or aperiodically by the terminal equipment; and finally, the terminal equipment sends uplink data according to the transmission resources distributed by the network equipment. However, this authorization transmission method requires a process of performing a service request to a network device via a terminal device to perform uplink transmission resource authorization, which results in a higher time delay and a higher signaling overhead, and as the type and number of the terminal device increase, the requirement for time delay is higher, and resources are more and more scarce, therefore, the grant-free transmission is proposed, the grant-free transmission is that the terminal equipment directly uses the specific grant-free transmission resources to send the uplink data, the terminal equipment does not need to request the network equipment for the uplink transmission resources, the time delay can be reduced, and signaling overhead can be saved, but since the unlicensed transmission needs to compete for uplink transmission resources, different terminal devices can compete for the same uplink transmission resources, resulting in collision, which results in poor reliability of data transmission and improved reliability of data transmission.

Detailed Description

It should be understood that the technical solutions of the embodiments of the present application may be applied to various communication systems, for example: a global system for mobile communications (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a long term evolution (long term evolution, LTE) system, a LTE Frequency Division Duplex (FDD) system, a LTE Time Division Duplex (TDD) system, a universal mobile telecommunications system (universal mobile telecommunications system, UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a Wireless Local Area Network (WLAN) or a future Generation wireless communication system (WLAN 5G), and the like.

Fig. 1 shows a communication system 100 to which an embodiment of the present application is applied. The communication system 100 may include a terminal device 110 that may refer to an access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user equipment. An access terminal may be a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device having wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device, a terminal in a 5G network, etc.

The network device 120 may be a network side device that performs wireless communication with the terminal device 110, for example, an access point of wireless fidelity (Wi-Fi), a base station of next generation communication, such as a gNB or a small station of 5G, a micro station, a Transmission Reception Point (TRP), a base station of 2G, 3G, and 4G, a relay station, an access point, a vehicle-mounted device, a wearable device, and the like.

It should be understood that there may be one or more terminal devices 110, and the embodiment of the present application is described by taking only one terminal device as an example.

In this embodiment of the present application, two sending manners, namely, an authorization manner and an authorization-free manner, may be adopted for sending data by a terminal device, and the authorization-based manner and the authorization-free manner are described below.

And the authorization mode comprises a traditional authorization mode and an enhanced authorization mode. The traditional authorization method comprises the following steps: when terminal device 110 needs to send uplink data to network device 120, terminal device 110 sends a Scheduling Request (SR) message to network device 120, the scheduling request message is used to request network device 120 that terminal device 110 has uplink data to transmit, after receiving the scheduling request message, network device 120 sends indication information to terminal device 110, the indication information indicates a location of a Physical Uplink Control Channel (PUCCH) of a Buffer Status Request (BSR) message for sending data by the terminal device 110, the terminal device 110 sends the BSR message to the network device 120 on the PUCCH according to the location indicated by the indication information, the BSR message includes a data amount of uplink data that the terminal device 110 currently needs to transmit, the network device 120 allocates transmission resources for transmitting the uplink data to the terminal device 110 according to the BSR message, and the terminal device 110 sends the uplink data to the network device 120 according to the transmission resources allocated by the network device 120. The enhanced authorization method comprises the following steps: terminal device 110 obtains a location of a BSR message in a PUCCH in a Radio Resource Control (RRC) reconfiguration message, when terminal device 110 needs to send uplink data to network device 120, terminal device 110 sends a BSR message to network device 120, where the BSR message is used to request network device 120 that the terminal device has uplink data to transmit, the BSR message further includes a data amount that the terminal device needs to transmit, after network device 120 receives the BSR message, a transmission resource for transmitting the uplink data is allocated to terminal device 120 according to the BSR message, and terminal device 110 sends the uplink data to network device 120 according to the transmission resource allocated to network device 120.

The terminal device 110 of the conventional authorization method and the enhanced authorization method needs to send a scheduling request message or a BSR message, which wastes signaling overhead, and needs multiple steps to acquire the transmission resource for sending uplink data, which results in a long time delay. For example, in a future network system, ultra-reliable and low latency communication (URLLC) has a high requirement on latency, and if an authorized transmission mode is adopted, the requirement on latency cannot be met.

In the unlicensed mode, the network device 120 may pre-configure a specific unlicensed transmission resource, when the terminal device 110 needs to send uplink data to the network device 120, the terminal device 110 competes for the transmission resource with other terminal devices in the specific unlicensed transmission resource, if the terminal device can compete for the transmission resource, the terminal device 110 sends the uplink data to the network device 120 on the contended transmission resource, and if the terminal device does not compete for the transmission resource, the terminal device 110 cannot send the uplink data to the network device 120, so that the data reliability of the unlicensed mode is limited to a certain extent.

Therefore, in view of the above problems, in the method for transmitting data provided in the embodiment of the present application, the network device may count the usage of the current uplink transmission resource in real time, and indicate the usage of the current uplink transmission resource to the terminal device using the uplink transmission resource state information, and the terminal device determines whether to transmit uplink data in an authorization manner or in an authorization-free manner according to the usage of the current uplink transmission resource, so that a manner of transmitting uplink data may be flexibly selected, and reliability of data transmission may be improved.

The technical solutions of the embodiments of the present application are described below with reference to the accompanying drawings.

Fig. 2 illustrates a method 200 for transmitting data according to an embodiment of the present application, where the method 200 includes:

s210, the network equipment sends uplink transmission resource state information to the terminal equipment, and the uplink transmission resource state information is used for indicating the use condition of uplink resources.

S220, the terminal equipment receives uplink transmission resource state information sent by the network equipment, and the terminal equipment determines a sending mode of uplink data at least according to the uplink transmission resource state information, wherein the sending mode comprises an authorization mode or an authorization-free mode.

Optionally, the uplink transmission resource status information may be used to indicate a usage of the uplink unlicensed transmission resource and/or a usage of the uplink licensed transmission resource. Optionally, the usage of the uplink unlicensed transmission resource may be represented by a collision probability, where the collision probability represents a probability that multiple terminal devices use the same transmission resource, and of course, this embodiment is not limited thereto, and the usage of the uplink unlicensed transmission resource may be represented by other parameters, for example, the number of terminal devices currently using the unlicensed transmission resource, and the like; the usage of the uplink grant transmission resource may be represented by a load, where the load represents a ratio of occupied grant transmission resources to total grant transmission resources, and of course, the embodiment of the present application is not limited thereto, and the usage of the uplink grant transmission resource may be represented by other parameters, for example, the number of terminal devices currently using the grant transmission resource, and the like.

As an example, when the uplink transmission resource state information is used to indicate a collision probability of an uplink grant-free transmission resource, the terminal device determines which way to use to transmit uplink data according to the collision probability and a preset collision threshold or a collision threshold configured by the network device, when the collision probability is greater than the collision threshold, the terminal device determines to use an authorization way to transmit uplink data, and when the collision probability is smaller than or equal to the collision threshold, the terminal device determines to use an grant-free way to transmit uplink data.

As an example, when the uplink transmission resource status information indicates both the collision probability of the uplink unlicensed transmission resource and the load of the uplink licensed transmission resource, the terminal device determines which way to transmit the uplink data according to the collision probability and the load. The protocol stipulates or presets the following thresholds, namely a conflict threshold 1, a conflict threshold 2 and a conflict threshold 3, and a loading threshold 1, a loading threshold 2 and a loading threshold 3, wherein the conflict threshold 1 is larger than the conflict threshold 2, the conflict threshold 2 is larger than the conflict threshold 3, the loading threshold 1 is larger than the loading threshold 2, and the loading threshold 2 is larger than the loading threshold 3. And when the collision probability is greater than the collision threshold 2 and less than the collision threshold 1, and the load is less than the load threshold 2 and greater than the load threshold 3, the terminal equipment determines that the uplink data is sent by adopting an authorization mode. And when the collision probability is smaller than the collision threshold 2 and larger than the collision threshold 3, and the load is larger than the load threshold 2 and smaller than the load threshold 1, the terminal equipment determines to adopt an authorization mode to send the uplink data.

The above examples are for better explaining the method of transmitting data according to the embodiments of the present application, and do not set any limit to the present application.

As an alternative embodiment, S220 includes: and the terminal equipment determines the sending mode of the uplink data according to the time delay requirement of the uplink data and the uplink transmission resource state information.

Optionally, the sum of the ninth probability and the tenth probability is 1.

Specifically, as shown in table 2, the first conflict threshold is conflict threshold 1, the second conflict threshold is conflict threshold 2, the third conflict threshold is conflict threshold 3, the fourth conflict threshold is conflict threshold 4, the fifth conflict threshold is conflict threshold 5, the sixth conflict threshold is conflict threshold 6, the judgment of the terminal device is based on the same principle as table 1, when the terminal device is smaller than a certain conflict threshold, the non-authorization mode is selected, when the terminal device is larger than a certain conflict threshold, the authorization mode is selected, when the terminal device is different from table 1, when the time delay requirement is in a certain range, the conflict probability is between two conflict thresholds, the non-authorization mode can be selected with a certain probability, the authorization mode can be selected with another probability, specifically, when the time delay requirement of the uplink data is low time delay, the probability of the non-authorization mode is selected to be greater than the probability of the authorization mode, when the time delay requirement of the uplink data is high time delay, the probability of selecting the authorization mode is greater than that of the authorization-free mode, so that the reliability of data transmission can be improved. For example, in table 2, when the collision probability is greater than or equal to the collision threshold 1 and less than or equal to the collision threshold 2, the terminal device selects the authorization-exempt mode with a probability of 0.7 to transmit the uplink data, and the terminal device selects the authorization mode with a probability of 0.3 to transmit the uplink data.

Optionally, there may be at least two conflict thresholds, conflict threshold 1, conflict threshold 2, conflict threshold 3, conflict threshold 4, conflict threshold 5, and conflict threshold 6, that are the same. Alternatively, the collision threshold 1, the collision threshold 2, the collision threshold 3, the collision threshold 4, the collision threshold 5, and the collision threshold 6 may be different from each other.

It should be understood that, for convenience of description, the foregoing only divides the range of the delay requirement by the first delay threshold and the second delay threshold, and in practical applications, the range of the delay requirement may need to be divided, for example, the range of the delay requirement may be divided by 5 or 10 delay thresholds, and similarly, when the delay threshold value is 5 values, the range may be divided into 6 delay ranges, and then the collision threshold value may be 6 (one delay range corresponds to one collision threshold value) or 12 (one delay range corresponds to two collision threshold values); when the delay threshold is 10 values, the delay threshold may be divided into 11 delay ranges, and then the collision thresholds may be 11 (one delay range corresponds to one collision threshold) or 22 collision thresholds, or 5 or 10 (one delay range corresponds to two collision thresholds).
