Description

Indication method, device and system

Technical Field

The present application relates to the field of communications, and in particular, to an indication method, apparatus, and system.

Background

With the further evolution of Communication technologies, a fifth Generation mobile Communication technology (5th-Generation, 5G) -New air interface/Radio (New Radio, NR) covers multiple vertical services, including enhanced mobile broadband (eMBB) service, ultra-reliable and ultra-low latency (URLLC) service, and Massive Machine Type Communication (mtc) service, so as to meet user requirements. Aiming at URLLC services such as industrial automation, telemedicine and automatic driving, the 5G-NR technology realizes low delay and high reliability by adopting modes such as protocol stack processing and different subcarrier intervals in a physical layer so as to ensure that the requirements of Quality of Service (QoS) are met.

Currently, in wireless communication, in order to support a User Equipment (UE) to perform inter-frequency or inter-system neighbor measurement, a base station configures a measurement GAP (GAP) for the UE, and the UE only performs measurement in the measurement GAP and does not perform data transmission. Therefore, when a measurement gap is met in the service data transmission process, data receiving and transmitting are stopped, and pilot frequency measurement or inter-system neighbor measurement is performed. Therefore, service data cannot be processed in time in the measurement gap, extra receiving and sending delay is brought to the service data, and service time delay is increased.

For a service with a high delay requirement, such as a URLLC service, when a measurement gap is encountered during the transmission of service data, that is, the service transmission collides with the measurement gap, the increase of the service transmission delay caused by the measurement gap cannot meet the QoS requirement of the service.

Disclosure of Invention

The embodiment of the application provides an indication method and device to reduce transmission delay of data.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, an indication method is provided, which may include: the access equipment determines that the effective sending time of the first data is overlapped with the measurement gap of the terminal; and the access equipment sends indication information to the terminal, wherein the indication information is used for indicating the terminal to receive the first data in the measurement gap.

By the indication method provided by the application, when the access equipment overlaps the measurement gap, the terminal is indicated by the indication information to receive the data in the measurement gap, so that the increase of the measurement gap on the data transmission delay is avoided, namely, the data transmission delay is reduced, and the QoS requirement of the service is met.

In a possible implementation manner, the indication method provided by the present application may further include: the access equipment determines the effective sending time of the first data; the access equipment compares the measurement gap of the terminal according to the effective sending time of the first data, and determines whether the effective sending time of the first data is overlapped with the measurement gap.

In a possible implementation manner, the determining, by the access device, a valid transmission time of the first data includes: if the first data is service data newly received by a higher layer of the access equipment, the access equipment determines the effective sending time of the first data, and is downlink transmission time corresponding to the time after the time when the higher layer receives the first data and the time when the data is transmitted from the higher layer to a lower layer of the access equipment. The access device executes the scheme of the application when the high-level entity newly receives the data, pre-judges whether the effective sending time of the newly received data is overlapped with the measurement gap, and instructs the terminal to receive the data in the measurement gap when the data is overlapped, thereby effectively avoiding the increase of the measurement gap to the data transmission delay in time.

Wherein, the downlink transmission time corresponding to a certain time includes: if the moment is at a downlink transmission moment, taking the downlink transmission moment at the moment as the downlink transmission moment corresponding to the moment; and if the time is not the downlink transmission time, taking the next downlink transmission time of the time as the downlink transmission time corresponding to the time.

The downlink transmission time refers to a time configured in the system and dedicated to downlink transmission. For example, the downlink Transmission Time may be a downlink Transmission Time Interval (TTI).

In a possible implementation manner, the determining, by the access device, a valid transmission time of the first data includes: if the first data is the next data to be transmitted in the logical channel cache, the access device determines the effective transmission time of the first data, and the effective transmission time is the downlink transmission time corresponding to the transmission ending time of the currently transmitted data. Before sending data, the access device prejudges whether the effective sending time of the data to be sent is overlapped with the measurement gap, and when the effective sending time of the data to be sent is overlapped with the measurement gap, the access device instructs the terminal to receive the data in the measurement gap, so that the increase of the measurement gap to the data transmission delay is avoided.

In a possible implementation manner, the determining, by the access device, a valid transmission time of the first data includes: if the first data is data to be transmitted in the logical channel cache, the access device determines an effective transmission time of the first data, which is a downlink transmission time corresponding to a transmission end time of previous data of the first data in the logical channel cache. Before sending data, the access device prejudges whether the effective sending time of the data to be sent is overlapped with the measurement gap, and when the effective sending time of the data to be sent is overlapped with the measurement gap, the access device instructs the terminal to receive the data in the measurement gap, so that the increase of the measurement gap to the data transmission delay is avoided.

In one possible implementation, the first data may include DCI of the first service data, and/or the first service data.

In the mobile communication, a terminal accesses a core network through access equipment to access a data network connected with the core network to realize services. In the process, when the terminal implements the service, the data transmitted between the terminal and the data network is called service data of the service. The traffic data is transmitted on a Physical Downlink Shared Channel (PDSCH). In a mobile network, an access device configures Downlink Control Information (DCI) for each service data and sends the DCI to a terminal, where the DCI is used to instruct the terminal to send related Information of the service data, and the DCI is carried on a Physical Downlink Control Channel (PDCCH) for transmission. The DCI for instructing the terminal to transmit the first service data is referred to as DCI of the first service data.

Optionally, the DCI and the service data indicated by the DCI may be sent at the same downlink transmission time, or may be sent at different downlink transmission times. When the first service data and the DCI of the first service data are transmitted at the same downlink transmission time, the first data includes the DCI of the first service data and the first service data.

It should be noted that the first service data is any service data, and is not specific to a certain service data.

In one possible implementation, the indication information may include a dedicated downlink signal, that is, the dedicated downlink signal is configured as the indication information, and the terminal is instructed to receive the first data in the measurement gaps that overlap at the effective transmission time of the first data. The type of the dedicated downlink signal may be configured according to actual requirements, which is not specifically limited in this embodiment of the present application. The special downlink signal is configured as the indication information, so that the modification of the information in the existing network is avoided, and the scheme compatibility is high.

In one possible implementation, the indication information may include a dedicated DCI, that is, a configuration-dedicated DCI as the indication information, which instructs the terminal to receive the first data in the measurement gaps that overlap at the effective transmission time of the first data. The dedicated DCI is distinguished from a conventional DCI indicating a resource for transmitting traffic data. The special DCI is configured as the indication information, thereby avoiding the modification of the information in the existing network and having high scheme compatibility.

In a possible implementation manner, the sending, by the access device, the indication information to the terminal includes: and the access equipment sends indication information to the terminal at a preset time domain position before the measurement gap. Therefore, the terminal can monitor at the preset time domain position to receive the indication information conveniently, and the efficiency of the terminal for acquiring the indication information is improved.

In a possible implementation manner, the preset time domain position may be a downlink transmission time after the indication information is generated; alternatively, the preset time domain position may be a designated downlink transmission time.

If the indication information is generated and is at a downlink transmission time, the downlink transmission time is the downlink transmission time after the indication information is generated; and if the downlink transmission time is not the downlink transmission time after the indication information is generated, the next downlink transmission time is the downlink transmission time after the indication information is generated.

In a possible implementation manner, the sending, by the access device, the indication information to the terminal includes: the access equipment sends DCI of second service data to the terminal, and the DCI of the second service data carries indication information; and the effective transmission time of the DCI of the second service data is earlier than that of the first data. In the implementation mode, extra bits are added to the existing DCI for transmitting the indication information, thereby avoiding the indication information occupying valuable transmission resources and saving the transmission resources.

In a possible implementation manner, the second service data is previous service data of the first service data.

In a possible implementation manner, the sending, by the access device, the indication information to the terminal includes: an access device transmits a Media Access Control (MAC) Control Element (CE) carrying indication information to a terminal. The extra bit is added to the existing MAC CE for transmitting the indication information, so that the indication information is prevented from occupying precious transmission resources, and the transmission resources are saved.

The MAC CE is a data unit carried in a Protocol Data Unit (PDU).

In a possible implementation manner, the first data may be data mapped from a higher layer entity of the access device to a Radio Bearer (RB); correspondingly, the determining, by the access device, that the effective transmission time of the first data overlaps with the measurement gap of the terminal specifically includes: when the higher layer entity maps the first data to the RB, the access equipment determines that the effective transmission time of the first data is overlapped with the measurement gap. Because the higher entity maps the data to the RB, and the time margin is enough from the effective transmission time of the data, the access device has enough time to generate and transmit the indication information, and the terminal also has enough time to receive the indication information and prepare to receive the data in the measurement gap according to the indication information, thereby improving the feasibility of the scheme.

In a possible implementation manner, the first data may be data newly received by the access device, and there is no RB to transmit the first data; correspondingly, the determining, by the access device, that the effective transmission time of the first data overlaps with the measurement gap of the terminal specifically includes: when the access equipment triggers and establishes the RB for transmitting the first data, the effective transmission moment of the first data is determined to be overlapped with the measurement gap. Because the access device triggers the time for establishing the RB and has enough time margin from the effective transmission time for transmitting data on the RB, the access device has enough time for generating and transmitting the indication information, and the terminal also has enough time for receiving the indication information and preparing to receive data in the measurement gap according to the indication information, thereby improving the feasibility of the scheme.

In a possible implementation manner, the first data may be data to be sent in a logical channel buffer of a service to which the first data belongs. Accordingly, the access device determines that the valid transmission time instant of the first data overlaps with the measurement gap before transmitting the first data.

In a possible implementation manner, the indication method provided by the present application may further include: the access equipment configures a timer for the terminal, and the timer is started at a preset time. Correspondingly, the indication information is used for indicating the terminal to receive the first data in the measurement gap, and specifically includes: the indication information is used for indicating the terminal to receive the first data and stop measuring during the running period of the timer in the measurement gap, and stop receiving the first data when the timer in the measurement gap is overtime. By configuring the timer and adopting the mode of combining the timer with the indication information, the indication terminal receives data during the running period of the timer in the measurement gap, the data transmission delay and the neighbor cell measurement are considered, and the network quality is ensured on the basis of reducing the data transmission delay.

In a possible implementation manner, the preset timing may include: the terminal receives first data; or the terminal receives the indication information.

In a possible implementation manner, the indication method provided by the present application may further include: the access equipment configures a timer for the terminal, wherein the timer is started at a preset time, so that the terminal receives first data and stops measuring during the running period of the timer in the measurement interval, and stops receiving the first data when the timer in the measurement interval is overtime. By configuring the timer and adopting the mode of combining the timer with the indication information, the indication terminal receives data during the running period of the timer in the measurement gap, the data transmission delay and the neighbor cell measurement are considered, and the network quality is ensured on the basis of reducing the data transmission delay.

In a possible implementation manner, the indication information may also be used to instruct the terminal to stop measuring in the whole measurement gap; alternatively, the indication information may also be used to instruct the terminal to perform the measurement after receiving the first data in the measurement gap.

In a possible implementation manner, the indication method provided by the present application may further include: the access equipment sends a measurement instruction to the terminal, wherein the measurement instruction is used for instructing the terminal to stop measuring in the whole measurement gap, or the measurement instruction is used for instructing the terminal to execute measurement after the terminal receives the first data in the measurement gap.

The preset threshold is configured, the indication terminal is indicated to measure when receiving the indication information, and the indication terminal receives data in the measurement gap when the measurement result meets the requirement, so that both data transmission delay and neighbor cell measurement are considered, and the network quality is ensured on the basis of reducing the data transmission delay.

By the indication method provided by the application, the terminal receives data in the measurement gap according to the indication of the access equipment, so that the increase of the measurement gap to the data transmission delay is avoided, namely the data transmission delay is reduced, and the QoS requirement of the service is met.

In one possible implementation, the indication information may include a dedicated DCI, or a dedicated downlink signal. And a special downlink signal or special DCI is configured as indication information, so that the modification of the information in the existing network is avoided, and the scheme compatibility is high.

In one possible implementation manner, the receiving, by the terminal, the indication information from the access device may include: and the terminal monitors and receives the indication information at a preset time domain position before the measurement gap. Therefore, the terminal can monitor at the preset time domain position to receive the indication information conveniently, the efficiency of the terminal for obtaining the indication information is improved, and resources are saved.

When the preset time domain position is the designated downlink transmission time, the sending position of the indication information is known to the terminal, and the terminal only needs to monitor and receive the indication information at the preset time domain position. And when the preset time domain position is the downlink transmission time after the indication information is generated, the terminal needs to monitor constantly to receive the indication information.

For a high-reliability network, the link quality of the network is relatively stable within a period of time, and the reduction of measurement does not affect the network performance, so that the application provides an indication method for reducing the transmission delay of data when the effective sending time of the data is overlapped with the measurement gap configured by the terminal when the access device sends the data to the terminal, so as to meet the Qos requirement of the service. The basic principle is as follows: the access device determines that the sending time of the data sent to the terminal is overlapped with a certain measuring gap according to the service requirement, and indicates the terminal to receive the data in the measuring gap.

On the other hand, the embodiment of the application provides a terminal. Fig. 3 illustrates a terminal 30 associated with various embodiments of the present application. The terminal 30 may be the terminal 102 in the wireless communication system architecture shown in fig. 2. As shown in fig. 3, the terminal 30 may include: a processor 301, a memory 302, a transceiver 303.

In another aspect, an embodiment of the present application provides an indication method, which is applied to a communication process between a terminal and an access device. The operation executed by the terminal described in this application may be understood as being executed by the terminal, and may also be understood as being executed by a functional unit or a chip in the terminal. The operation performed by the access device described in this application may be understood as being performed by the access device, or may also be understood as being performed by a functional unit or a chip in the access device, which is not specifically limited in this embodiment of the application, and only the operation performed by the base station is described below. The functional unit or chip in the access device or terminal for executing the indication method provided by the present application may be referred to as an indication apparatus referred to in the present application.

As shown in fig. 4, an indication method provided in an embodiment of the present application may include:

s401, the access device determines the effective sending time of the first data.

The first data includes DCI of the first service data and/or the first service data. When the terminal implements the service, the data transmitted with the data network is called service data. Traffic data is transmitted on the PDSCH. The DCI is used for indicating the terminal to send the relevant information of the service data, and the DCI is carried on the PDCCH for transmission. The DCI instructing the terminal to transmit the first service data is referred to as DCI of the first service data.

Optionally, the DCI and the service data indicated by the DCI may be sent at the same downlink transmission time, or may be sent at different downlink transmission times. When the first service data and the DCI of the first service data are transmitted at the same downlink transmission time, the first data includes the DCI of the first service data and the first service data. It should be noted that the first service data is any service data, and is not specific to a certain service data.

Illustratively, the first service data may be data of URLLC service.

Alternatively, when there is data to be transmitted to the terminal, S401 may be performed to determine the valid transmission time of the data.

Illustratively, several scenarios are provided for performing S401:

in scenario 1, the first data is data newly received by a higher-layer entity of the access device, and there is no RB to transmit the data, and when the access device triggers establishment of the RB to transmit the data, the access device executes S401 to determine an effective transmission time of the newly received data.

Scene 2, the first data is data mapped to the RB by the higher layer entity of the access device, and when the higher layer entity of the access device maps the data to the RB, S401 is executed to determine the effective transmission time of the data.

Scene 3, the first data is data to be sent in the logical channel cache of the service to which the first data belongs, and the access device executes S401 to determine the effective sending time of the data before sending the data.

It should be noted that, in scenario 3, the timing when the access device executes S401 before sending the data may be configured according to actual requirements, which is not specifically limited in this embodiment of the present application. For example, the access device may perform S401 to determine the effective transmission time of the first data when the currently transmitted data field has the first data interval of N data to be transmitted. The specific value of N is configured according to actual requirements, which is not specifically limited in the embodiment of the present application.

In a possible implementation, when the first data is newly received by the higher layer entity of the access device, or the first data is mapped to an RB by the higher layer entity of the access device, the determining, by the access device, a valid transmission time of the first data includes: the access device determines the effective sending time of the first data, and is the time when the high-layer entity receives the first data or the time when the high-layer entity maps the first data to the RB, and the downlink transmission time corresponding to the time after the time length of the data transmitted from the high-layer entity to the low-layer entity of the access device is added.

For example, the downlink transmission time may be a downlink TTI.

For example, suppose that the higher layer of the access device newly receives data 1 at time t1, the duration for the higher layer entity of the access device to transmit the data to the lower layer entity of the access device is t2, the downlink transmission time 1 is from time a to time B, the next downlink transmission time (downlink transmission time 2) of the downlink transmission time 1 is from time C to time D, and if t1+ t2 belongs to the downlink transmission time 1, the effective transmission time t1+ t2 of the data 1; if t1+ t2 is between time B and time C, the effective transmission time of data 1 is time C.

In a possible implementation, when the first data is data to be transmitted in the logical channel cache, the access device determines an effective transmission time of the first data, which is a downlink transmission time corresponding to a transmission end time of previous data of the first data in the logical channel cache.

For example, if the data 2 is the next data to be transmitted in the logical channel buffer, and the transmission start time and the transmission duration of the currently transmitted data are known, the transmission end time of the currently transmitted data can be determined, and the data 2 is used as the next data to be transmitted, and the effective transmission time of the data 2 is the downlink transmission time corresponding to the transmission end time of the currently transmitted data.

It should be noted that if there are several data to be transmitted between the data 2 and the currently transmitted data, the effective transmission time of the next data to be transmitted can be determined according to the currently transmitted data, the transmission time of the next data to be transmitted is added, the transmission end time of the next data to be transmitted is determined, and so on until the effective transmission time of the data 2 is determined.

S402, the access device determines that the effective transmission moment of the first data is overlapped with the measurement gap of the terminal.

In this case, the access device determines whether the effective transmission time of the first data overlaps with the measurement gap according to the effective transmission time of the first data determined in S401, compared with the known measurement gap of the terminal (the measurement gap of the terminal is configured by the access device, and therefore, the information is known to the access device).

An overlap may be understood as a valid transmission instant of the first data falling within a measurement gap, i.e. a time period belonging to the measurement gap in the time domain.

In S402, the access device determines that the effective transmission time of the first data overlaps with the measurement gap of the terminal, and the access device performs S403 and transmits the first data at the effective transmission time of the first data, so as to ensure that the terminal normally receives the first data.

Further, if the access device determines that the effective sending time of the first data is not overlapped with any measurement gap of the terminal, the access device directly sends the first data at the effective sending time of the first data, and the terminal can normally receive the first data.

For example, as described in the three scenarios of performing S401 in S401, the access device may determine that the effective transmission time of the first data overlaps with the measurement gap of the terminal in S402.

S403, the access device sends indication information to the terminal, wherein the indication information is used for indicating the terminal to receive the first data in the measurement gap overlapped with the effective sending time of the first data.

It should be noted that, the content, the format, and the sending position of the indication information may all be configured according to actual requirements, which is not specifically limited in the embodiment of the present application, and all information for indicating the terminal to receive the first data in the measurement gap overlapping with the effective sending time of the first data may be referred to as the indication information herein, and is not limited by the format, the content, and the sending position.

Optionally, the indication information may include identification information of a measurement gap overlapping with the first data valid transmission time, and is used to instruct the terminal to identify the measurement gap overlapping with the first data valid transmission time.

The identification information of the measurement gap is used for uniquely identifying the measurement gap, and may be a time identifier of the measurement gap or a name identifier of the measurement gap.

In a possible implementation manner, the sending, by the access device, the indication information to the terminal in S403 includes: and the access equipment sends indication information to the terminal at a preset time domain position before the measurement gap.

Optionally, the preset time domain position may be a downlink transmission time after the indication information is generated; alternatively, the preset time domain position may be a designated downlink transmission time.

The definition of the downlink transmission time after the indication information is generated includes: if the indication information is generated and is at a downlink transmission time, the downlink transmission time is the downlink transmission time after the indication information is generated; and if the indication information is generated and then is at the non-downlink transmission time, the downlink transmission time next to the time of generating the indication information is the downlink transmission time after generating the indication information.

In a possible implementation, the indication information may be configured to be dedicated to instruct the terminal to receive the first data in a measurement gap overlapping with a valid transmission time of the first data, and the dedicated information may include dedicated DCI or a dedicated downlink signal, which is not specifically limited in this embodiment of the present invention. When the dedicated information is a dedicated downlink signal, the type and form of the signal may be configured according to actual requirements, which is not specifically limited in this embodiment of the application.

In one possible implementation, an extra bit may be configured in existing information in the existing network as the indication information.

For example, the indication information may be carried in the existing DCI and sent to the terminal, and S403 is specifically implemented as: the access equipment sends DCI of second service data to the terminal, and the DCI of the second service data carries indication information; and the effective transmission time of the DCI of the second service data is earlier than that of the first data.

Optionally, the second service data is previous data of the first data in the data sent to the terminal.

It should be noted that, the position of the indication information in the DCI of the second service data may be configured according to actual requirements, and this embodiment of the present application is not specifically limited to this.

It should be further noted that the second service data and the first service data may be two data units in the same service data.

For another example, the indication information may be carried in an existing MAC CE and sent to the terminal, and S403 is specifically implemented as: the access equipment can send the MAC CE carrying the indication information to the terminal.

It should be noted that, the position of the indication information in the MAC CE may be configured according to actual requirements, and this is not specifically limited in this embodiment of the application.

Further optionally, the indicating information used for indicating the terminal to receive the first data in the measurement gap overlapping with the effective transmission time of the first data may specifically include the following several cases:

case a, the indication information may also be used to instruct the terminal to stop measuring in the entire measurement gap that overlaps with the effective transmission time of the first data.

Wherein, stopping measurement, namely not measuring, the two can be replaced with each other.

In case a, the terminal receives only data and does not make any measurement during the entire period of the measurement gap indicated by the indication information.

In case B, the indication information may be further used to instruct the terminal to perform measurement after receiving the first data in a measurement gap overlapping with the effective transmission time of the first data.

The network is configured with an indication flag after the data transmission is finished, for example, the access device may send an end identifier after the data transmission is finished, the data transmission may be determined to be finished according to the identifier, and the terminal determines that the data reception is finished after receiving the identifier. The form and content of the end mark are not particularly limited in the present application.

And the condition C and the indication information are used for indicating the terminal to receive the first data and stop measuring during the running period of the timer in the measurement gap, and stopping receiving the first data when the timer in the measurement gap is overtime.

In case C, the indication method provided in the embodiment of the present application further includes: the access equipment configures a timer for the terminal, and the timer is started at a preset time.

Optionally, the preset time may include: the terminal receives first data; or the terminal receives the indication information. The content of the preset time is not specifically limited in the embodiment of the present application.

In a possible implementation, unlike the cases a and B, the access device may send, to the terminal, a measurement instruction separately from the indication information, where the measurement instruction is used to instruct the terminal to stop measuring in the entire measurement gap overlapping with the effective transmission time of the first data, or the measurement instruction is used to instruct the terminal to perform measurement after receiving the first data in the measurement gap overlapping with the effective transmission time of the first data.

In a possible implementation, the indication information is further configured to instruct the terminal to perform measurement in a next measurement gap where the indication information is received, obtain a measurement result, and determine whether to receive the first data in the measurement gap according to a size relationship between the measurement result and a preset threshold.

For example, when the measurement result is greater than or equal to the preset threshold, the terminal receives the first data in the measurement gap, and when the measurement result is less than the preset threshold, the terminal performs the measurement in the measurement gap without receiving the data.

In a possible implementation, the access device may further instruct, through the first instruction, the terminal to perform measurement in a next measurement gap in which the instruction information is received, obtain a measurement result, and determine whether to receive the first data in the measurement gap according to a size relationship between the measurement result and a preset threshold. Accordingly, the access device sends the first indication to the terminal.

The contents and forms of the first instructions are not limited to the embodiments of the present application. The first indication may be sent in combination with the indication information, or may be sent separately, which is not specifically limited in this embodiment of the application.

It should be noted that the value of the preset threshold may be configured according to actual requirements, and this is not specifically limited in the embodiment of the present application. For example, the preset threshold may be configured to guarantee a lower-bound network quality of the service Qos.

S404, the terminal receives indication information from the access equipment.

In S404, the terminal receives the indication information in a monitoring manner. The indication information received by the terminal in S404 and the indication information sent by the access device in S403 are already described in detail in S403, and are not described herein again.

In a possible implementation, the receiving, by the terminal, the indication information from the access device in S404 specifically includes: and the terminal monitors and receives the indication information at a preset time domain position before the measurement gap.

Optionally, the preset time domain position may be a downlink transmission time after the access device generates the indication information; alternatively, the preset time domain position may be a designated downlink transmission time.

When the preset time domain position is a known quantity for the terminal, for example, the preset time domain position is an appointed downlink transmission time, the terminal monitors and receives the indication information at the preset time domain position. When the preset time domain position is unknown to the terminal, for example, the preset time domain position is a downlink transmission time after the access device generates the indication information, the terminal continuously monitors to receive the indication information.

S405, the terminal receives the first data in the measurement gap overlapping with the effective transmission time of the first data.

In S405, the terminal determines a measurement gap in which data needs to be received according to the indication of the indication information, and waits for receiving data in the determined measurement gap until the data is received or until the measurement gap is finished.

Optionally, the terminal may start a timer at a preset time, receive the first data during a running period of the timer in a measurement gap overlapping with an effective transmission time of the first data, and stop receiving the first data when the timer in the measurement gap is overtime.

It should be noted that, the terminal may receive the first data in combination with whether the timer operates in the measurement gap overlapping with the effective transmission time of the first data, and the terminal may actively perform the reception, or may perform the reception according to the instruction of the instruction information, which is not specifically limited in this embodiment of the application.

In a possible implementation, the terminal receives the first data in combination with whether the timer is running or not in a measurement gap overlapping with a valid transmission time of the first data, as instructed by the indication information, in which case the indication information is further used to instruct the terminal to receive the first data and stop the measurement during the running of the timer in the measurement gap, and to stop receiving the first data when the timer in the measurement gap expires.

Optionally, when the terminal executes S405, S405 may be specifically implemented as: the terminal receives the first data in a measurement gap overlapped with the effective sending time of the first data and stops measuring in the whole measurement gap; or the terminal stops measuring when receiving the first data in the measurement gap, and performs measurement after receiving the first data in the measurement gap.

Optionally, when the terminal executes S405, according to the indication of the indication information, the S405 may be specifically implemented that the terminal receives the first data in a measurement gap overlapping with an effective transmission time of the first data, and stops measurement in the entire measurement gap; or the terminal stops measuring when receiving the first data in the measurement gap, and performs measurement after receiving the first data in the measurement gap.

Correspondingly, the indication information is also used for indicating the terminal to stop measuring in the whole measuring gap; or, the indication information is further used to instruct the terminal to perform measurement after the terminal has received the first data in the measurement gap.

Optionally, when the terminal executes S405, according to a measurement instruction other than the instruction information, the method may specifically implement S405 that the terminal receives the first data in a measurement gap overlapping with an effective transmission time of the first data, and stops measurement in the entire measurement gap; or the terminal stops measuring when receiving the first data in the measurement gap, and performs measurement after receiving the first data in the measurement gap.

Correspondingly, as shown in fig. 5, the indication method provided in the embodiment of the present application may further include an optional step S406.

S406, the terminal receives a measurement instruction from the access equipment.

The measurement indication is used for indicating the terminal to stop measuring in the whole measurement gap, or the measurement indication is used for indicating the terminal to perform measurement after the terminal receives the first data in the measurement gap.

In one possible implementation, as shown in fig. 5, the indication method provided in the embodiment of the present application may further include an optional step S407.

And S407, the terminal executes measurement in the next measurement interval of the received indication information to obtain a measurement result.

Optionally, the terminal executes S406 actively, or according to an instruction of the instruction information, or according to a first instruction other than the instruction information, which is not specifically limited in this embodiment of the application.

In a possible implementation, when the terminal performs S406 according to the indication of the indication information, the indication information is further used to instruct the terminal to perform measurement in the next measurement gap in which the indication information is received.

In a possible implementation, when the terminal performs S406 according to the indication of the first indication, the terminal further needs to receive the first indication from the access device.

Further optionally, corresponding to S406, S405 may specifically be implemented as: and the terminal receives the first data in the measurement gap when the measurement result is greater than or equal to the preset threshold. Further, the terminal performs measurement in the measurement gap when the measurement result is smaller than a preset threshold.

It should be noted that the execution time sequence of the steps included in the indication method provided in the embodiment of the present application may be configured according to actual requirements, and fig. 4 and fig. 5 only illustrate the execution sequence of the steps, and are not specifically limited thereto.

In another aspect, an embodiment of the present application provides a method for receiving data, which is applied to a communication process between a terminal and an access device. As shown in fig. 6, the method of receiving data may include:

s601, the access equipment configures a timer for the terminal.

S602, the terminal starts a timer at a preset time;

For example, the preset time may be when the terminal receives data.

And S603, the terminal receives data in the measurement gap during the running period of the timer and stops measurement.

Optionally, the terminal receives data in the whole measurement gap during the running of the timer to stop measuring.

The above-mentioned scheme provided by the embodiment of the present application is introduced mainly from the perspective of interaction between network elements. It is understood that the access device and the terminal include hardware structures and/or software modules for performing the functions in order to realize the functions. Those of skill in the art would readily appreciate that the various illustrative elements and algorithm steps described in connection with the embodiments disclosed herein may be implemented as hardware or combinations of hardware and computer software. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

In the embodiment of the present application, the access device and the terminal may be divided into the functional modules according to the above method examples, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. It should be noted that, in the embodiment of the present application, the division of the module is schematic, and is only one logic function division, and there may be another division manner in actual implementation.

For example, in the case of dividing each functional module in an integrated manner, fig. 7 shows a schematic structural diagram of the access device 70. The access device 70 includes: a processing module 701 and a transceiver module 702.

In a possible implementation, the processing module 701 is configured to determine that an effective transmission time of the first data overlaps with a measurement gap of the terminal; the transceiver module 702 is configured to send, to the terminal, indication information when the processing module 701 determines that the valid sending time of the first data overlaps with the measurement gap of the terminal, where the indication information is used to indicate the terminal to receive the first data in the measurement gap.

In one possible implementation, the processing module 701 is configured to configure a timer for the terminal, so that the terminal starts the timer at a preset time and stops measuring when receiving data in a measurement gap during the running of the timer

Further, as shown in fig. 7, the access device 70 may further include a storage module 703 for storing the first data.

Specifically, the functions/implementation procedures of the processing module 701 and the transceiver module 702 in fig. 7 can be implemented by the processor 201 in fig. 2 calling the computer execution instructions stored in the memory 202. Alternatively, the function/implementation procedure of the processing module 701 in fig. 7 may be implemented by the processor 201 in fig. 2 calling a computer executing instruction stored in the memory 202, and the function/implementation procedure of the transceiver module 702 in fig. 7 may be implemented by the transceiver 203 in fig. 2.

Since the access device 70 provided in this embodiment can execute the above-mentioned indication method or the data receiving method, the technical effects obtained by the access device can refer to the above-mentioned method embodiments, and are not described herein again.

Alternatively, for example, in the case where the functional modules are divided in an integrated manner, fig. 8 shows a schematic configuration diagram of the terminal 80. The terminal 80 includes: a processing module 801 and a transceiver module 802.

In a possible implementation, the transceiver module 802 is configured to receive indication information from the access device, where the indication information is used to instruct the terminal 80 to receive the first data in the measurement gap; the processing module 801 is configured to receive the first data in the measurement gap after the transceiver module 802 receives the indication information.

In a possible implementation, the processing module 801 is configured to start a timer at a preset time, and stop the measurement when the terminal receives data through the transceiver module 802 during a measurement gap during the running of the timer.

In the present embodiment, the terminal 80 is presented in a form of dividing each functional module in an integrated manner. A "module" herein may refer to a particular ASIC, a circuit, a processor and memory that execute one or more software or firmware programs, an integrated logic circuit, and/or other device that provides the described functionality. In a simple embodiment, those skilled in the art will appreciate that the terminal 80 may take the form shown in FIG. 3.
