Description

Transmission time processing method and related equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a transmission time processing method and a related device.

Background

At present, the use of the authorized frequency band cannot meet the rapidly increasing mobile data traffic, so that the unauthorized frequency band needs to be fully utilized besides improving the data transmission capability of the authorized frequency band. The unlicensed frequency band is a frequency band that anyone can use to deploy wireless communication, and for example, a wireless telephone, bluetooth, a remote controller and the like can use the unlicensed frequency band to transmit data under the condition that the regulatory requirements are met.

However, when the terminal uses the unlicensed frequency band, it needs to use a contention mode to acquire transmission resources, such as transmission time and frequency point, of the unlicensed frequency band. However, for the wireless mesh network, the relay node needs to perform two contention to transmit the data of the parent node to the child node, for example, the relay node needs to contend for a resource first and obtain the data of the child node by using the resource; when the resources are contended again, the acquired data is transmitted to the father node, so that the channel utilization rate is not improved.

Disclosure of Invention

The application provides a transmission time processing method and related equipment, which can use channel resources in a transmission time sharing mode and improve the channel utilization rate.

In a first aspect, the present application provides a transmission time processing method, in which a first device determines a transmission time unit configured to a second device, and the second device grants a node for transmission time of the first device; the first equipment sends a transmission time grant message to the second equipment according to the transmission time unit configured to the second equipment; the transmission time grant message includes a unit indication message, the unit indication message is used to indicate a transmission time unit configured to the second device, and the transmission time unit configured to the second device is used to transmit data between the second device and its child node. Therefore, compared with the method for obtaining the transmission time in a competition mode in the prior art, the method and the device for obtaining the transmission time in the competition mode can enable the second equipment to directly use the allocated transmission time unit, and avoid the problem of low channel utilization rate caused by competition.

In a possible implementation manner, a first device receives a time requirement message sent by a second device, where the time requirement message is used to request the first device to configure a transmission time unit for the second device; the first device determining a transmission time unit configured to a second device, comprising: and the first equipment determines a transmission time unit configured to the second equipment according to the time demand message.

In this application, the time requirement message is used to request a transmission time unit of the second device, and the second device grants a node for the transmission time of the first device, that is, the first device may grant transmission time for the second device, and correspondingly, the first device may also be referred to as a transmission time sharing node, that is, the first device may share the transmission time acquired by itself with other devices; the first device is also a parent node of the second device; the transmission time unit of the second device is used for transmitting data to be transmitted between the second device and the child node of the second device.

In addition, the transmission time grant message includes unit indication information indicating a transmission time unit configured to the second device. When the transmission time grant message is sent in a broadcast mode, the transmission time grant messages received by the second devices are the same, but the transmission time units configured to the second devices can be identified according to the unit indication information in the transmission time grant messages.

In a possible implementation manner, a first device sends uplink scheduling information to a second device, where the uplink scheduling information is used to indicate a time-frequency resource for uplink transmission by the second device; the first device receives a time demand message sent by a second device, and the method comprises the following steps: and the first equipment receives the time demand information sent by the second equipment on the time frequency resource. For example, after the second device receives the uplink scheduling information sent by the first device, the second device may send a time requirement message on the time-frequency resource indicated by the uplink scheduling information, and may consider that the uplink scheduling information is a trigger message for the second device to send the time requirement message, that is, the uplink scheduling information has functions of allocating the time-frequency resource for uplink transmission and triggering the second device to send the time requirement message.

In a possible implementation manner, a first device may send a trigger configuration message to a second device, where the trigger configuration message includes cycle indication information and/or event indication information, and the cycle indication information is used to indicate a time period for the second device to send the time requirement message; the event indication information is used for indicating the second device to send a trigger event of the time demand message, for example, the data to be transmitted of the second device exceeds a certain threshold; correspondingly, the time requirement message is sent by the second device according to the time period indicated by the period indication information and/or the trigger event indicated by the event indication information. In this way, the second device reports the time demand message to the first device periodically or when a trigger event occurs, so that the first device can know the time demand condition of each second device, and the transmission time unit is distributed to each second device in time.

In a possible implementation manner, the second device may transmit the time demand message according to the time period indicated by the period indication information or the time indicated by the event indication information in combination with the uplink scheduling information. For example, when the time period indicated by the period indication information or the event indicated by the event indication information does not arrive or occurs, the second device may report the time requirement message to the first device as long as receiving the uplink scheduling information. For another example, the second device may send an uplink scheduling information request message to the first device to request uplink scheduling information when the time period indicated by the period indication information arrives or is about to arrive, so as to send a time requirement message on the time-frequency resource indicated by the uplink scheduling information; correspondingly, the second device may also send an uplink scheduling information request message to the first device to request uplink scheduling information when the event indicated by the event indication information occurs, so as to send the time requirement message on the time-frequency resource indicated by the uplink scheduling information.

The implementation method triggers the second device to send the time demand message when the transmission time sharing function can be carried out, thereby saving the signaling overhead.

In another possible implementation manner, the first device may determine a transmission time unit configured to the second device, and then obtain the first transmission duration, and the first device determines, according to the first transmission duration and the transmission time unit configured to the second device, the transmission time unit allocated to the second device in the first transmission duration, so that the transmission time grant message sent by the first device to the second device carries the transmission time unit allocated to the second device in the first transmission duration.

The manner in which the first device obtains the first transmission duration may be obtained by contention, or obtained by a parent node of the first device, such as a transmission time sharing node of the first device.

In a possible implementation manner, the transmission time unit configured to the second device is a subset of a first transmission time length, and the first transmission time length is a transmission time length obtained by the first device.

In another possible implementation manner, as shown in fig. 2b, in the transmission time processing method, before step 101, the first device may further receive a time requirement message sent by the second device, where the time requirement message is used to request the first device to configure a transmission time unit for the second device.

That is, in the transmission time processing method shown in fig. 2b, before step 101, the method may further include:

Correspondingly, in step 104, the sending, by the second device, the time demand message to the first device may be: the second equipment sends a time demand message on the time frequency resource indicated by the uplink scheduling information; correspondingly, in step 106, the step of receiving, by the first device, the time requirement message sent by the second device may be: and the first equipment receives the time demand information sent by the second equipment on the time frequency resource.

Specifically, the first transmission duration needs a part of the transmission time unit to transmit the time grant message in addition to a part of the transmission time unit used for transmitting data between the first device and the second device, so that the remaining transmission time units in the first transmission duration except the two parts can be configured to the second device, and the second device uses the transmission time unit to transmit data between the second device and its child node. For example, the first transmission duration includes at least a first transmission time unit and a second transmission time unit, the first transmission time unit being used for data transmission between the first device and the second device; the transmission time unit configured to the second device is a subset of the second transmission time unit. The data may include user plane data and control plane data, where the user plane data may also be referred to as traffic data, and the control plane data generally refers to control signaling and the like.

Accordingly, in 101, the determining, by a first device, a transmission time unit configured to a second device includes:

the first device determines a transmission time unit configured to the second device according to the time demand message.

For example, when the triggering event is that the third transmission duration required by the second device is greater than a certain threshold, the second device may send a time requirement message to the first device to request the first device to allocate a transmission time unit to the second device. The third transmission time length is the time length required for transmitting data between the second equipment and the child node thereof; for another example, the triggering event is that data to be transmitted between the second device and its child node reaches a certain threshold.

Therefore, in the embodiment of the present invention, the second device may send the time requirement message to the first device according to the time period and/or the trigger event, so that the first device can know the transmission time requirement condition of the second device in time, and thus, a transmission time unit is allocated to the second device in time to transmit the data to be transmitted.

301. the first equipment acquires a first transmission duration;

302. the first equipment determines a second transmission time length required for data transmission between the first equipment and the second equipment;

303. the first equipment judges whether to execute a transmission time sharing function according to the first transmission time length and the second transmission time length; if the transmission time sharing function is executed, executing step 304, otherwise ending the process;

Optionally, if the transmission time sharing function is not executed, the first device may continue to execute step 301 to obtain the first transmission duration until the transmission time sharing function is determined to be executed. The first device determines whether to execute a transmission time sharing function according to the first transmission time length and the second transmission time length, and specifically includes: the first device determines whether the first transmission duration is greater than the second transmission duration, and if so, performs a transmission time sharing function to determine transmission time units allocated to the second device according to the remaining unused transmission time units. For example, the first transmission duration includes at least a first transmission time unit and a second transmission time unit, the first transmission time unit being used for data transmission by the first device and the second device; the transmission time unit configured to the second device is a subset of the second transmission time unit.

304. The first device sends a trigger message to the second device.

Therefore, the embodiment of the invention can trigger the second device to send the time demand message when the first device can share the transmission time, thereby saving the signaling overhead between the first device and the second device.

Optionally, in the transmission time processing method shown in fig. 4, 304 may not be executed, but 101 may be directly executed to determine the transmission time unit configured to the second device, that is, the embodiment may issue the transmission time grant message without the second device reporting the time requirement message, that is, the embodiment may determine that the transmission time sharing function can be executed in the first device, and may configure the shared transmission time unit for the second device. In this embodiment, 101 also performs the step 101 shown in fig. 2a, i.e. the first device determines the transmission time unit allocated to the second device.
