Description

data transmission method, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a data transmission method, a terminal device, and a network device.

background

in fourth and fifth generation mobile communication systems (4G, 5G or NR systems), Discontinuous Reception (DRX) is introduced. The method can enable user equipment (UE, also called terminal equipment) to periodically enter a sleep state, and wake up from the sleep state when monitoring is needed without monitoring a Physical Downlink Control Channel (PDCCH), so that the UE can achieve the purpose of saving power. Although this has some impact on the latency of data transmission, it makes sense to perform DRX in view of the more important power consumption of the UE if such latency does not impact the user experience.

The DRX mechanism is implemented differently in idle and connected states, and relatively speaking, the DRX mechanism in connected state is as shown in fig. 1: the time period for identity wakeup (On Duration) is the time for the UE to monitor the downlink PDCCH, and during this time period, the UE is in the awake state. The period of time that identifies a DRX Opportunity (Opportunity for DRX) is the DRX sleep time, i.e., the time the UE goes to sleep without monitoring PDCCH subframes for power saving. It can be seen that the longer the time for DRX sleep, the lower the power consumption of the UE, but the delay of the corresponding traffic transmission will increase. "Opportunity for DRX" may also be described as DRX off, or DRX inactive state.

In the prior art, when the UE is in the DRX inactive state, if uplink data arrives, the UE may perform uplink transmission. As shown in fig. 2, the uplink transmission (UL transmission) in fig. 2 may be a Scheduling Request (SR), a preamble (preamble) of random access, or a protocol data unit (MAC PDU) of an uplink medium access control layer, such as uplink transmission configured with grant, which is not limited herein.

After the UE sends the SR, it needs to wait for downlink scheduling information, and the UE will be in a DRX activated state, i.e. the UE will perform a downlink PDCCH listening operation. However, for some services, the requirement for service delay is not strict, and if uplink transmission is sent in the DRX inactive state, additional energy consumption overhead is caused, and power consumption is increased.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings.

currently, the terminal device may perform uplink data transmission in the DRX inactive period, for example, SR transmission, transmission of a random access preamble, transmission of configuration grant data, and the like.

(1) SR transmission

Currently in DRX inactive state, the UE may send an SR. The UE tells the network whether uplink resources are needed for data transmission through the SR, but does not tell the network how much uplink data is sent (this is told through the buffer status report BSR). After receiving the SR, the network side allocates uplink resources to the UE to send the BSR.

(2) Transmission of random access preamble

When the UE is not configured with the SR, the UE may request uplink resources through a Random Access Channel (RACH). The RACH may also be initiated while DRX inactive state.

(3) Sending of configuration authorisation data

Configuration granted type 1(configured granted type 1):

In this configuration, the transmission resource of the UE is configured by the network side through the RRC signaling, the RRC configures the resource location and also configures the contents such as the physical layer transmission parameters, and after receiving the configuration information, the UE can send data on the resource.

specifically, the physical layer transmission parameters include: frequency domain position, antenna port number, precoding layer number, MCS, etc.

Configuration grant type 2(configured grant type 2):

In this way, the same as the conventional SPS, the transmission resource of the UE is also configured through RRC signaling, and after the resource location is configured, the RRC does not configure the physical layer transmission parameters. After receiving the RRC configuration information, the UE needs to wait for the indication information of the DCI, so as to activate the RRC configured resource, and then the UE can send data at the corresponding resource location. Or deactivating the resources configured by the RRC according to the indication information of the DCI of the physical layer, and stopping data transmission by the UE at the corresponding resource position.

In a long term evolution LTE system, only semi-static configuration of configuration grant type 2 exists. Meanwhile, the default DRX activation time and the configuration authorization position are matched, and the authorization resource cannot be configured in the DRX inactive state, namely the configuration authorization data cannot be sent in the DRX inactive state.

However, in the NR system, there are two semi-static configurations, configuration grant type 1 and configuration grant type 2, and it can be supported to transmit configuration grant data in the DRX inactive state at present.

Some uplink data, such as WeChat or partial HTTP traffic, are not very strict in latency requirements, but if the uplink data is still frequently sent in the DRX inactive state, the power saving effect of the UE is seriously affected.

Based on this, an embodiment of the present invention provides a data transmission method, which is applied to a terminal device, and as shown in fig. 3, includes:

Step 301: energy saving configuration information is received.

the energy-saving configuration information is used for instructing the terminal equipment to delay and/or stop sending the target uplink data in the DRX inactive period.

the energy-saving configuration information is configured by the network equipment through Radio Resource Control (RRC) signaling;

Or the energy-saving configuration information is configured by the network device based on at least one of radio bearer RB configuration information, logical channel configuration information, and scheduling request SR configuration information.

step 302: and delaying and/or stopping sending the target uplink data in the discontinuous reception DRX inactive period according to the energy-saving configuration information.

wherein, the target uplink data comprises: a Scheduling Request (SR) triggered in the DRX inactive period;

Or, a preamble of random access triggered during the DRX inactivity period;

Here, the terminal device receives the energy saving configuration information, and delays and/or stops transmitting the target uplink data in the discontinuous reception DRX inactivity period according to the energy saving configuration information, so as to reduce power consumption of the terminal device.

As an optional implementation manner, the energy saving configuration information includes an energy saving identifier, and when the energy saving identifier is a preset identifier, the terminal device is instructed to delay and/or stop sending the target uplink data in the DRX inactivity period. And if the energy-saving flag is set, indicating the terminal equipment to delay and/or stop sending the target uplink data in the DRX inactive period when the flag is true.

as another optional implementation manner, the energy saving configuration information includes timer threshold information, and when the timing duration of the terminal device timer is greater than the timer threshold information, the terminal device delays and/or stops sending the target uplink data in the DRX inactivity period;

and when the timing duration of the timer of the terminal equipment is greater than the threshold information of the timer, the terminal equipment is in the DRX inactive period. The timer threshold information may specifically be a total timing duration of the timer, and when the timer of the terminal device is overtime, the terminal device is instructed to delay and/or stop sending the target uplink data in the DRX inactivity period.

Specifically, as shown in fig. 4, after a DRX active period timer (DRX on duration timer) or a DRX inactive period timer (DRX inactivity timer) times out, the UE turns on the timer of the terminal device, and the UE enters a shallow sleep mode, where the shallow sleep mode is that the terminal device does not monitor a PDCCH channel any more; and when the timer of the terminal equipment is overtime, the UE enters deep sleep, wherein the deep sleep means that the terminal equipment stops monitoring the PDCCH and simultaneously stops sending uplink data, the stopping of sending the uplink data comprises stopping sending SR, stopping sending Preamble, stopping sending uplink MAC PDU, stopping executing CSI measurement of downlink channel state information, and stopping executing at least one of RRM measurement. In fig. 4, DRX on denotes a DRX active period, and DRX off denotes a DRX inactive period.

in the embodiment of the invention, when the time delay requirement of the uplink data is not strict, the network equipment configures the energy-saving configuration information, and the terminal equipment delays and/or stops sending the target uplink data in the DRX (discontinuous reception) inactive period according to the energy-saving configuration information, so that the power consumption of the terminal equipment in the DRX inactive state is reduced on the basis of meeting the requirement of data time delay.

it should be noted that the DRX active period in the embodiment of the present invention refers to a period in which the terminal device is in an active state, and the DRX inactive period refers to a period in which the terminal device is in an inactive state. And when the terminal equipment is in an activated state, the PDCCH monitoring operation is executed, and when the terminal equipment is in an inactivated state, the PDCCH monitoring operation is not executed. The DRX active state includes: the duration period also includes a period during which the UE turns on the receiving device to receive data at the DRX opportunity.

Wherein, in the step 302, according to the energy saving configuration information, delaying transmission of the target uplink data in the discontinuous reception DRX inactivity period includes:

As an optional implementation manner, delaying target uplink data to a target time for transmission includes:

here, the DRX active period specifically refers to a first DRX active period after the DRX inactive period, the time unit may specifically be a time slot, a subframe, a transmission time interval TTI, or an orthogonal frequency division multiplexing OFDM symbol, and the available uplink time unit refers to existence of an SR resource or a physical layer random access channel PRACH resource or a configuration grant uplink resource.

For example, as shown in fig. 5, when the terminal device triggers a scheduling request SR in a DRX inactive period and there is SR transmission resource, the terminal device delays SR transmission until transmission in the first available uplink time unit of the next DRX active period.

as shown in fig. 6, when the terminal device triggers random access in the DRX inactive period and there is a random access resource, the terminal device delays preamble transmission until the terminal device transmits in the first available uplink time unit of the next DRX active period.

as shown in fig. 7, when the terminal device has the above configuration grant type 1 and type 2 in the DRX inactive period and has the configuration grant resources, the terminal device delays the transmission of the configuration grant data until the terminal device transmits the configuration grant data in the first available uplink time unit of the next DRX active period.

When the energy-saving configuration information is configured based on at least one of Radio Bearer (RB) configuration information, logical channel configuration information and Scheduling Request (SR) configuration information;

as another optional implementation manner, delaying the target uplink data to the target time for transmission includes:

When the terminal equipment generates first target uplink data in a DRX inactive period and energy-saving configuration information corresponding to the first target uplink data indicates that the first target uplink data is delayed to be sent in the DRX inactive period, the first target uplink data is delayed to be sent in a first available uplink time unit of the DRX active period after the DRX inactive period;

or, when the terminal device generates first target uplink data in a DRX inactive period, energy saving configuration information corresponding to the first target uplink data indicates that the first target uplink data is delayed to be transmitted in the DRX inactive period, and after the first target uplink data is generated, second target uplink data is generated in the DRX inactive period, and energy saving configuration information corresponding to the second target uplink data indicates that the second target uplink data is not delayed to be transmitted in the DRX inactive period, the first target uplink data is delayed to a target time to be transmitted, where the target time is a time after the second target uplink data is transmitted.

For example, when the terminal device triggers the first scheduling request SR in the DRX inactive period, and the energy saving configuration information corresponding to the first scheduling request SR indicates that the first scheduling request SR is delayed to be transmitted in the DRX inactive period, and there is a transmission resource of the first scheduling request SR, the terminal device delays the transmission of the first scheduling request SR until the terminal device transmits the first available uplink time unit in the next DRX active period.

or, as shown in fig. 8, after triggering the first scheduling request SR, the terminal device further triggers a second scheduling request SR in the DRX inactive period, and the energy saving configuration information corresponding to the second scheduling request SR indicates that the transmission of the second scheduling request SR is not delayed in the DRX inactive period, then transmits the second scheduling request SR at the transmission time corresponding to the transmission resource of the second scheduling request SR, and transmits the first scheduling request SR after transmitting the second scheduling request SR.

here, after the second scheduling request SR is transmitted, the terminal device has an inactive state to become an active state, and at this time, the first scheduling request SR is transmitted, which reduces the number of times of waking up the terminal device, thereby reducing the energy consumption of the terminal device.

In addition, according to the current standard, after the second scheduling request SR is sent, the base station sends scheduling information to the UE, so that the UE can cancel sending the first scheduling request SR after sending the BSR.

Further, when the network device configures the energy saving configuration information based on at least one of radio bearer RB configuration information, logical channel configuration information, and scheduling request SR configuration information, the following method may be specifically implemented.

The first method is as follows: specifically, an energy-saving identifier is added to the logical channel configuration information, and when the energy-saving identifier is true, the terminal device is instructed to delay and/or stop sending the target uplink data in the DRX inactive period, and when the energy-saving identifier is false, the terminal device is instructed not to delay and/or stop sending the target uplink data in the DRX inactive period, which may specifically be implemented by the following codes.

The second method comprises the following steps: specifically, when the energy saving flag is added to the SR configuration information, the terminal device is instructed to delay and/or stop transmitting the target uplink data in the DRX inactive period when the energy saving flag is true, and when the energy saving flag is false, the terminal device is instructed not to delay and/or stop transmitting the target uplink data in the DRX inactive period, which may specifically be implemented by the following codes.

according to the data transmission method provided by the embodiment of the invention, the network equipment configures the energy-saving configuration information for the terminal equipment, and the terminal equipment delays and/or stops sending the target uplink data in the discontinuous reception DRX (discontinuous reception) inactive period according to the energy-saving configuration information, so that the power consumption of the terminal equipment in the DRX inactive state is reduced.

step 901: and transmitting energy-saving configuration information, wherein the energy-saving configuration information is used for indicating the terminal equipment to delay and/or stop transmitting the target uplink data in the DRX inactive period.

Or, a preamble of random access triggered during the DRX inactivity period;

preferably, the energy saving configuration information is used to instruct the terminal device to delay the target uplink data to the target time for transmission in the DRX inactive period.

the target time comprises a first available uplink time unit of a DRX active period after the DRX inactive period;

As another optional implementation manner, the energy saving configuration information includes timer threshold information, and when the time duration of the timer of the terminal device is greater than the timer threshold information, the terminal device is instructed to delay and/or stop sending the target uplink data in the DRX inactivity period;

according to the data transmission method provided by the embodiment of the invention, the network equipment configures the energy-saving configuration information for the terminal equipment, so that the terminal equipment delays and/or stops sending the target uplink data in the discontinuous reception DRX (discontinuous reception) inactive period according to the energy-saving configuration information, and the power consumption of the terminal equipment in the DRX inactive state is reduced.
