The method comprises the steps that a terminal does not monitor first scheduling information in a first time period after sending a first message comprising uplink data to network equipment, monitors the first scheduling information for scheduling first downlink data after the first time period, and stops monitoring the first scheduling information when the condition for stopping monitoring is met.

Description

Monitoring method and device

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a monitoring method and a monitoring device.

Background

At present, when a terminal is in an idle (idle) state or an inactive (inactive) state, if the terminal needs to send uplink service data to a network device, the terminal needs to initiate a random access process, and switch from the idle/inactive state to a connected (connected) state to send the uplink service data to the network device. If the uplink service data is packet data and the amount of data is small, at this time, sending the small amount of data also needs to initiate a complete random access process, which may increase signaling overhead and power consumption of the terminal.

In order to reduce the signaling overhead and power consumption of the terminal, the terminal may send packet data to the network device during the random access process. After receiving the packet data, the network device may send a downlink data to the terminal, where the downlink data includes a bottom layer acknowledgement message for acknowledging completion of sending the packet data and a high layer feedback message including the network device.

However, the feedback speed of the bottom layer acknowledgement message is generally faster, for example, within 5ms, and the generation of the high layer feedback message is generally slower, which may require more than 200 ms. If the network device determines to send the high-level feedback information to the terminal, the network device needs to wait until the high-level feedback information is generated, and then send a Physical Downlink Control Channel (PDCCH) and a corresponding message for scheduling, and the interval time is long, so that the terminal monitors the corresponding PDCCH in a pre-configured search space for a long time, and the power consumption of the terminal is increased.

In the unconnected state, the terminal is not connected to a network device (e.g., an access network device), but the network device may store a context of the terminal, and the terminal may receive one or more of a paging message, a synchronization signal, a broadcast message, or system information from the network device, but cannot perform data transmission such as voice call, large data volume internet access, and the like with the network device.

The idle state or the inactive state may be referred to as an unconnected state or a dormant state.

In order to reduce power consumption for transmitting packet data when the terminal is in a non-connected state, the terminal transmits the packet data to the network device through a random access procedure or a configuration scheduling (CG) procedure. The random access procedure may include a four-step random access procedure and a two-step random access procedure. The small data may refer to data having a bit number less than or equal to a preset value, and the preset value may be set as needed. Illustratively, the packet data may be data of several bits (bits), data of several tens of bits or data of several hundreds of bits, and the preset value may be 100 bits, 10 bits, or the like, for example.

Referring to fig. 1a, for a four-step random access procedure, the method may include: and step (1), the terminal sends a first message (msg1) to the network equipment to inform the network equipment of a random access request. The first message may also be referred to as a random access preamble (random access preamble). And (2) after receiving the msg1, the network device sends a random access response to the terminal, wherein the random access response may also be referred to as a second message (msg 2). And (3) after receiving the random access response, the terminal sends a third message (msg3) to the network equipment, wherein the msg3 can include packet data and other information. And step (4), the network equipment sends a fourth message (msg4) to the terminal, wherein the fourth message can comprise a response message determined by the bottom layer of the network equipment and high-layer feedback information which is determined by the high layer of the network equipment and corresponds to the packet data. The network device may include an access network device, a core network device, a device of a service provider (such as a server), and the like. It should be noted that, in the first step, when the terminal sends the random access preamble to the network device, the preamble (preamble sequence) used by the terminal is randomly selected from an optional preamble set. msg2/msg3/msg4 all require network devices to be scheduled to a terminal through a Physical Downlink Control Channel (PDCCH), such as: before transmitting msg2/msg3/msg4, the network equipment transmits a PDCCH for scheduling msg2/msg3/msg4, and transmits msg2/msg3/msg4 on time-frequency resource positions indicated by the PDCCH.

Referring to fig. 1b, the two-step random access procedure may include: and step (1), the terminal sends msgA to the network equipment, wherein the msgA can comprise preamble and can also comprise packet data and other information. And (2) the network equipment receives the msgA and replies an msgB to the terminal, wherein the msgB can comprise a response message determined by the bottom layer of the network equipment and high-layer feedback information which is determined by the high layer of the network equipment and corresponds to the packet data. The network device may include an access network device, a core network device, a device of a service provider (such as a server), and the like. It should be noted that, when the terminal sends msgA to the network device, the preamble used by the terminal is randomly selected from an optional preamble set. The latter msgB requires the network device to be scheduled to the terminal through the PDCCH, such as: before transmitting the msgB, the network device may transmit a PDCCH for scheduling the msgB, and transmit the msgB on a time-frequency resource position indicated by the PDCCH.

Referring to fig. 1c, for the CG process, it may include: step (1), the network equipment sends uplink resource configuration information to the terminal and configures uplink resources for the terminal to send uplink data. And (2) the terminal sends a configuration scheduling message comprising packet data to the network equipment on the uplink resource configured by the network equipment. And (3) the network equipment receives the packet data and sends a configuration scheduling response to the terminal, wherein the configuration scheduling response can comprise a response message determined by the bottom layer of the network equipment and high-layer feedback information which is determined by the high layer of the network equipment and corresponds to the packet data. The network device may include an access network device, a core network device, a device of a service provider (such as a server), and the like.

When the terminal communicates with the network device, a protocol layer as shown in fig. 2 may be established between the terminal and the network device, and as shown in fig. 2, the terminal may include a Transmission Control Protocol (TCP)/Internet Protocol (IP) layer and a physical layer (PHY). The network device may include a TCP/IP layer, a physical layer. The TCP/IP layer of the terminal may be referred to as an upper layer of the terminal, the physical layer of the terminal may be referred to as a lower layer of the terminal, the TCP/IP layer of the network device may be referred to as an upper layer of the network device, and the physical layer of the network device may be referred to as a lower layer of the network device.

When the terminal sends uplink data to the network device, the TCP/IP of the terminal generates the uplink data, such as: and the physical layer of the terminal modulates the uplink data code and then transmits the modulated uplink data code to the physical layer of the network equipment through an air interface. After the physical layer of the network device receives the uplink data, the physical layer of the network device generally sends a "response message of the physical layer" to the physical layer of the terminal, so that the terminal knows that the uplink data packet in the physical layer has been correctly transmitted, and meanwhile, the physical layer of the network device can decode and demodulate the uplink data and send the decoded and demodulated uplink data to a TCP/IP layer of the network device. After receiving the uplink data, the TCP/IP layer of the network device generates a high-level feedback message of the TCP/IP layer, and feeds back the high-level feedback message to the terminal through the physical layer of the network device (as shown by a dotted line in fig. 2). Because the time for generating the high-level feedback information and sending the high-level feedback information is relatively long, usually 200ms, the terminal often receives the high-level feedback information after a long certain time after sending the packet data. At this time, if the terminal monitors the scheduling information for scheduling the high-level feedback information for a long time, power consumption of the terminal is increased.

In order to solve the problem of large power consumption of the terminal, the embodiment of the present application provides a monitoring method for reducing power consumption of the terminal for monitoring scheduling information. The following describes a monitoring method for reducing power consumption of terminal monitoring scheduling information according to an embodiment of the present application with reference to the accompanying drawings.

The monitoring method provided in the embodiment of the present application may be used in any system of a fourth generation (4G) system, a Long Term Evolution (LTE) system, a fifth generation (5G) system, a New Radio (NR) system, a vehicle-to-any-object communication (V2X) system, and an internet of things system, and may also be applied to other next-generation communication systems, without limitation. The following describes a monitoring method provided in the embodiment of the present application, taking the communication system shown in fig. 3 as an example.

Fig. 3 is a schematic diagram of a communication system according to an embodiment of the present application, and as shown in fig. 3, the communication system may include a network device and a plurality of terminals, such as: terminal 1, terminal 2. In the system shown in fig. 3, the terminal may be in either an idle state or an inactive state. It should be noted that fig. 3 is an exemplary framework diagram, the number of nodes included in fig. 3 is not limited, and other nodes may be included in addition to the functional nodes shown in fig. 3, such as: core network devices, gateway devices, application servers, etc., without limitation. In addition, the network device may include an access network device, a core network device, a device of a service provider (such as a server), and the like, without limitation. In the embodiments of the present application, a network device including an access network device is taken as an example for description.

The following describes a monitoring method provided in an embodiment of the present application, taking a device for implementing a function of a terminal as an example.

In the system shown in fig. 3, in order to reduce power consumption of the terminal, after the terminal in the non-connected state transmits uplink data to the network device through the msg 3/msgA/configuration scheduling message, the terminal may not monitor the scheduling information for scheduling the msg4 or msgB or configuring the scheduling response for a period of time, and then starts to monitor the scheduling information. Or, two time periods are set, after the terminal sends uplink data to the network device through the msg 3/msgA/configuration scheduling message, scheduling information used for scheduling msg4 or msgB or configuring scheduling response is monitored in the first time period, the scheduling information is monitored in the first time period, and the scheduling information is not monitored in the second time period; or monitoring an indication message in the first time period, wherein the indication message indicates whether the terminal is to monitor in the second time period, and monitoring in the second time period according to the indication message. Therefore, the power consumption caused by continuously monitoring the PDCCH after the terminal sends the msg 3/msgA/configuration scheduling message can be reduced. Specifically, the monitoring method may be described with reference to the embodiments corresponding to fig. 5 to 10.

Fig. 5 is a monitoring method according to an embodiment of the present application, where a sleep duration of a terminal is increased by setting a time period during which scheduling information is not monitored, so as to reduce power consumption of the terminal. As shown in fig. 5, the method may include:

step 501: the terminal sends a first message to the network device.

The terminal may be any terminal in an idle state or an inactive state in the communication system shown in fig. 3. The network device may be any network device capable of providing network services for the terminal in the communication system shown in fig. 3.

Wherein the first message may include uplink data. The terminal may obtain the uplink data according to the following manner: and the high layer of the terminal generates data and sends the generated data to the bottom layer of the terminal, and the bottom layer of the terminal performs coding modulation on the received data to obtain uplink data. The related description of the high layer of the terminal and the bottom layer of the terminal can refer to fig. 2, and the process of generating data by the high layer of the terminal and the process of coding and modulating data by the bottom layer of the terminal can refer to the prior art and are not repeated.

In the embodiments of the present application, uplink data and downlink data are relative concepts, where uplink data may refer to data sent from a terminal to a network device, and downlink data may refer to data sent from the network device to the terminal.

For example, the terminal may send the first message to the network device through a four-step random access procedure, a two-step random access procedure, or a configuration scheduling procedure, where the sending method refers to the following modes (1.1) to (1.3):

mode (1.1), the terminal sends a first message to the network device through msg3 in a four-step random access procedure.

For example, the terminal may include the uplink data in a first message, include the first message in msg3 to send to the network device; alternatively, the uplink data is included in the first message, and the first message is sent to the network device as msg3, in this case, the first message may be referred to as msg 3.

In the mode (1.2), the terminal sends a first message to the network device through the msgA in the two-step random access process.

For example, the terminal may include the uplink data in a first message, include the first message in msgA, and transmit the msgA to the network device; or, the terminal includes the uplink data in the first message, and sends the first message to the network device as msgA, where the first message may be referred to as msgA.

Mode (1.3), the terminal sends a first message to the network device through the configuration scheduling message.

For example, the terminal may include the first message included in the uplink data in the configuration scheduling message, and send the configuration scheduling message to the network device on the uplink transmission resource pre-configured by the network device to the terminal; or, the terminal may include the uplink data in the first message, use the first message as a configuration scheduling message, and send the first message to the network device on an uplink transmission resource preconfigured to the terminal by the network device, where the first message may be referred to as the configuration scheduling message.

The embodiment of the present application does not limit the naming of the configuration scheduling message, and the configuration scheduling message may also be named as a pre-configuration message, a preset message, or a message with another name, without limitation.

The data volume transmitted by the three transmission modes is limited, such as: the data with less data volume is transmitted, in order to ensure the reliability of data transmission. For example, before performing step 501, the terminal determines whether the data amount of the uplink data is smaller than a preset value, and when determining that the data amount of the uplink data is smaller than the preset value, sends a first message to the network device, such as: and the terminal starts a radio frequency module of the terminal, and sends a first message to the network equipment through the radio frequency module by adopting any one of the modes (1.1) to (1.3). The radio frequency module may be the communication interface described in fig. 4.

The preset value can be set according to the requirement, and is not limited. If the data volume of the uplink data is smaller than the preset value, the uplink data is represented as packet data, and otherwise, if the data volume of the uplink data is larger than or equal to the preset value, the uplink data is represented as non-packet data. Specifically, the preset value may be specified in the standard, or may be configured by broadcasting through a system message of the network device.

Step 502: and the network equipment receives the first message and sends the first scheduling information and the first downlink data to the terminal.

Wherein the first scheduling information may be used for scheduling the first downlink data. The network device may send the first scheduling information and the first downlink data to the terminal, including: and the network equipment sends first scheduling information to the terminal through the PDCCH and sends first downlink data to the terminal at a time-frequency resource position indicated by the first scheduling information.

The first downlink data may be high-level feedback information corresponding to uplink data, and the first downlink data may be small packet data, that is, the data amount of the first downlink data is smaller than a preset value. Illustratively, the network device may obtain the first downlink data according to the following manner: after receiving the first message, the bottom layer of the network equipment decodes and demodulates the uplink data included in the first message and then sends the decoded and demodulated uplink data to the high layer of the network equipment; after the high layer of the network equipment receives the data sent by the bottom layer of the network equipment, high layer feedback information corresponding to the data is generated, the generated high layer feedback information is sent to the bottom layer of the network equipment, and the bottom layer of the network equipment carries out coding modulation on the high layer feedback information to obtain first downlink data.

The related descriptions of the high layer of the network device and the bottom layer of the network device may refer to fig. 2, and the process of generating the high layer feedback information by the high layer of the network device and the process of performing coding modulation on the high layer feedback information by the bottom layer of the network device may refer to the prior art and are not described in detail.

Illustratively, corresponding to the terminal sending the first message, the network device may send the first downlink data to the terminal in any one of the following manners (2.1) to (2.3):

in the mode (2.1), the network device sends the first downlink data to the terminal through the msg4 in the four-step random access process.

In the mode (2.2), the network device sends the first downlink data to the terminal through the msgB in the two-step random access process.

And in the mode (2.3), the network equipment sends the first downlink data to the terminal through configuring the scheduling response.

In the manner (2.3), in addition to the first downlink data, the configuration scheduling response may further include, without limitation, an underlying acknowledgement message included in the existing configuration scheduling response for indicating that the network device received the first message, and other information.

The embodiment of the present application does not limit the naming of the configuration scheduling response, and the configuration scheduling response may also be named as preconfigured information or preset information or information with other names, which is not limited.

It should be noted that the scheduling information may be, for example, PDCCH or other. For example, the first scheduling information may be named a first PDCCH, the second scheduling information may be named a second PDCCH, and so on.

Step 503: and the terminal does not monitor the first scheduling information in a first time period after the terminal sends the first message.

The first time period may be used to limit a duration for which the terminal does not monitor the scheduling information. The duration of the first time period, the starting time and/or the ending time of the first time period may be preconfigured to the terminal by the network device; alternatively, the duration of the first time period, and the start time and/or the end time of the first time period are predefined by a protocol, and are not limited.

Taking as an example that the duration of the first time period, the start time and/or the end time of the first time period may be preconfigured to the terminal by the network device, the terminal may receive a broadcast message from the network device, where the broadcast message includes the duration of the first time period, the start time and/or the end time of the first time period, and the terminal acquires the duration of the first time period, the start time and/or the end time of the first time from the broadcast message.

The duration of the first time period can be set as required. For example, the first time period may be determined according to the time when the higher layer of the network device generates the higher layer feedback information and the time when the lower layer of the network device performs coding modulation on the higher layer feedback information, such as: the duration of the first time period may be set to be less than or equal to the sum of the time for the higher layer of the network device to generate the higher layer feedback information and the time for the lower layer of the network device to code-modulate the higher layer feedback information.

For example, the terminal may configure a first timer (timing) according to a duration of the first time period, a start time and/or an end time of the first time period, where the duration of the first timer is equal to the duration of the first time period, a start time of the first timer corresponds to the start time of the first time period, start the first timer after the terminal sends the first message, and not monitor the first scheduling information during a validity period/running period of the first timer. In the embodiments of the present application, the terminal not monitoring the first scheduling information may mean that the terminal closes its radio frequency module and stops receiving and transmitting data/information.

Wherein the starting time of the first time period is related to the ending time of the first message. In one possible design, the starting time of the first time period may be set to be equal to or later than the end time of the first message, such as: the start time of the first time period may be an end time of first transmitting the first message, or the start time of the first time period may be a time domain position separated from the end time of first transmitting the first message by several slots/symbols after the end time of first transmitting the first message. As shown in fig. 6a to 6b, the start time of the first period is the end time t0 of the first message.

In yet another possible design, to ensure that the first message is successfully transmitted, the start time of the first time period may be set equal to or later than the time at which the first message is determined to be successfully transmitted. For example, the starting time of the first time period may be a time when the first message is determined to be successfully transmitted, or the starting time of the first time period may be a time domain position separated from the time when the first message is determined to be successfully transmitted by several slots/symbols after the time when the first message is determined to be successfully transmitted. For example, as shown in fig. 6d, the starting time of the first time period is time t1 when the first message is determined to be successfully transmitted.

In this embodiment of the application, the terminal may monitor information for scheduling retransmission of the first message in a third time period after the first message is sent for the first time, determine that the first message is successfully sent if the information for scheduling retransmission of the first message is not received in the third time period, otherwise, resend the first message to the network device according to the information for scheduling retransmission of the first message if the information for scheduling retransmission of the first message is monitored, and start the first time period after resending the first message. The information of the first message retransmission may be a first message retransmission indication, and the first message retransmission indication may instruct the terminal to resend the first message to the network device.

The duration of the third time period, and the start time and/or the end time of the third time period may be configured to the terminal by the network device, for example: the network equipment is configured to the terminal and the like through broadcast messages; alternatively, the duration of the third time period, the start time and/or the end time of the third time period may be predefined by a protocol.

For example, the terminal may configure a third timer according to the duration of the third time period, the start time and/or the end time of the third time period, where the duration of the third timer is equal to the duration of the third time period, the start time of the third timer corresponds to the start time of the third time period, after the terminal sends the first message, the terminal starts the third timer, and monitors information for scheduling retransmission of the first message within the validity period/running period of the third timer.

Wherein, the starting time of the third time period may be set to be equal to or later than the ending time of the first message, such as: the starting time of the third time period is the ending time of the first message, or the starting time of the third time period is after the ending time of the first message. For example, as shown in fig. 6d, the starting time of the third time period is the end time t0 of the first message being sent.

It should be noted that, the embodiments of the present application do not limit the naming of each time period, and the time period may also be named as a time window (window) or other names. For example, the first time period may be named a first time window, the second time period may be named a second time window, the third time period may be named a third time window, the fourth time period may be named a fourth time window, the fifth time period may be named a fifth time window, and so on.

In addition, each timer described in the embodiments of the present application may be replaced by a counter (counter), and a product of a count number of the counter and a time length counted each time is equal to a time length of the timer. For example, the first timer may be replaced with a first counter, the second timer may be replaced with a second counter, the third timer may be replaced with a third counter, the fourth timer may be replaced with a fourth counter, the fifth timer may be replaced with a fifth counter, and so on.

Step 504: and after the terminal passes a first time period, monitoring first scheduling information.

Wherein the first scheduling information may be used for scheduling the first downlink data. The description of the first scheduling information and the first downlink data may refer to the description in step 502, which is not repeated herein.

In a possible design, after a first time period elapses, for example, after the terminal starts its radio frequency module at the end time of the first time period, the first scheduling information is monitored, or, after the end time of the first time period, the terminal starts its radio frequency module at the ith time slot/symbol, and monitors the first scheduling information, where i is an integer greater than or equal to 1. For example, as shown in fig. 6a, the terminal starts monitoring the first scheduling information when the first period ends, and at this time, the time for ending monitoring the first scheduling information is not defined.

In another possible design, a second time period is set after the first time period, the terminal starts its own radio frequency module in the second time period, monitors the first scheduling information, i.e., a time period is divided for monitoring the first scheduling information, and the monitoring is performed in the time period, so that the power consumption of the terminal is saved. For example, as shown in any one of fig. 6b to 6d, the terminal sets a second time period after the first time period ends, and monitors the first scheduling information in the second time period.

The second time period may be used to limit a duration for the terminal to monitor the first scheduling information. The duration of the second time period, the start time and/or the end time of the second time period may be determined by the terminal according to the network device configuration, such as: the network device broadcasts the duration of the second time period, the starting time and/or the ending time of the second time period in the broadcast message, and the terminal receives the broadcast message and acquires the duration of the second time period, the starting time and/or the ending time of the second time period from the broadcast message. Alternatively, the duration of the second time period, the start time and/or the end time of the second time period may also be predefined by the protocol.

Wherein the start time of the second time period may be equal to or later than the end time of the first time period. Such as: the start time of the second period may be the end time of the first period, or the start time of the second period may be a time domain position spaced several slots/symbols after the end time of the first period from the end time of the first period. For example, as shown in any one of fig. 6b to 6d, the start time of the second time period is a time-domain position after the end time of the first time period and with a time interval between the end time of the first time period.

For example, the monitoring, by the terminal, the first scheduling information during the second time period may include: and the terminal determines the monitoring parameters in the second time period and monitors the first scheduling information according to the monitoring parameters in the second time period.

Wherein the monitoring parameters in the second time period may include: and one or more information of the configuration of the search space, the configuration of the CORESET and the RNTI corresponding to the first scheduling information. The configuration of the search space may include one or more of a monitoring period of the search space, a DCI format of downlink control information to be monitored, a number of candidates to be monitored, and an aggregation level to be monitored. The related definition of each parameter may refer to the existing description, and the manner in which the terminal monitors the first scheduling information according to the monitoring parameter of the second time period may refer to the existing description, which is not repeated.

The monitoring parameters in the second time period may also be determined by the terminal according to the configuration of the network device, such as: the network equipment broadcasts the monitoring parameters in the second time period in the broadcast message, and the terminal receives the broadcast message broadcasted by the network equipment and acquires the monitoring parameters in the second time period from the broadcast message.

It should be noted that, in each embodiment of the present application, the monitoring parameter in the second time period, the duration of the second time period, and the start time and/or the end time of the second time period may be configured to the terminal in the same broadcast message, or may be configured to the terminal in different broadcast messages.

Step 505: and when the condition for stopping monitoring is met, the terminal stops monitoring the first scheduling information.

The condition for stopping monitoring may include the following condition (one) or condition (two):

condition (one), the first downlink data is successfully received within the second time period.

For example, if the terminal monitors the first scheduling information in the second time period, the first downlink data is received according to the time-frequency resource position indicated by the first scheduling information, and the first downlink data is successfully received through verification, the monitoring of the first scheduling information is stopped, so that the energy consumption of the terminal is saved.

Taking fig. 6b as an example, if the terminal is at a certain time point from time t1 to time t2, for example: at the intermediate time between the time t1 and the time t2, the terminal may stop monitoring the first scheduling information from the time point when the first downlink data is successfully received from the time-frequency resource location indicated by the monitored first scheduling information.

Condition (two), the second period of time ends.

For example, the terminal may not monitor the first scheduling information all the time in the second time period, or the terminal monitors the first scheduling information in the second time period, but does not receive the first downlink data according to the time-frequency position information indicated by the first scheduling information in the second time period, and then the terminal may stop monitoring the first scheduling information when the second time period ends.

The condition for stopping monitoring may also include a condition (one) and a condition (two), monitoring is stopped when the condition (one) is satisfied in the second time period, and monitoring is stopped after the second time period elapses.

Taking fig. 6b as an example, if the terminal has not monitored the first scheduling information or has not received the first downlink data from time t1 to time t2, the terminal may stop monitoring the first scheduling information from time t 2.

By applying the method shown in fig. 5, the terminal may not monitor the scheduling information for scheduling the first downlink data in the first time period after the first message including the uplink data is sent, but may monitor the scheduling information for scheduling the first downlink data after the first time period is ended. Therefore, the sleep time from the terminal sending the first message to the monitoring of the scheduling information can be increased by setting the first time period, and the power consumption of the terminal is reduced.

For example, as shown in fig. 6a, a first period of time is set: time t0 to time t 1. And starting a first timer corresponding to the first time period at a time t0 after the terminal sends the first message to the network equipment, closing the radio frequency module of the terminal during the running period of the first timer, and not monitoring the first scheduling information until the first timer is finished. And starting the radio frequency module at t1 when the first timer is finished, and monitoring the first scheduling information. Alternatively, the start time of the first time period in fig. 6a may be later than time t0, separated from time t0 by one or more time slots/symbols; alternatively, the starting time of the first time period in fig. 6a may also be equal to or later than the time (not shown in fig. 6 a) at which the first message is determined to be successfully transmitted.

For another example, as shown in fig. 6b, a first period of time is set: t 0-t 1, second time period: time t1 to time t 2. And starting a first timer corresponding to the first time period at a time t0 after the terminal sends the first message to the network equipment, closing the radio frequency module of the terminal during the running period of the first timer, and not monitoring the first scheduling information until the first timer is finished. And starting a second timer corresponding to a second time period at the time t1 when the first timer is finished, starting a radio frequency module of the second timer during the running period of the second timer, and monitoring the first scheduling information. Alternatively, the start time of the first time period in fig. 6b may be later than time t0, separated from time t0 by one or more slots/symbols, or the start time of the first time period in fig. 6b may be equal to or later than the time (not shown in fig. 6 b) at which the first message is determined to be successfully transmitted; the start time of the second time period in fig. 6b may also be later than time t1, separated from time t1 by one or more slots/symbols.

For another example, as shown in fig. 6c, a first period of time is set: t 0-t 1, second time period: time t2 to time t 3. And starting a first timer corresponding to the first time period at a time t0 after the terminal sends the first message to the network equipment, closing the radio frequency module of the terminal during the running period of the first timer, and not monitoring the first scheduling information until the first timer is finished. And starting a second timer corresponding to a second time period at t2 after the first timer is finished, starting a radio frequency module of the second timer during the running period of the second timer, and monitoring the first scheduling information. Alternatively, the start time of the first time period in fig. 6c may be later than time t0, separated from time t0 by one or more slots/symbols, or the start time of the first time period in fig. 6c may be equal to or later than the time (not shown in fig. 6 c) at which the first message is determined to be successfully transmitted.

For another example, as shown in fig. 6d, three time periods are set: a first time period: t 1-t 2, second time period: t 3-t 4, third time period: time t0 to time t 1. And starting a third timer corresponding to a third time period at a time t0 after the terminal sends the first message to the network equipment, starting a radio frequency module of the terminal during the running period of the third timer, monitoring and scheduling information of retransmission of the first message, if the first message is not successfully sent, and starting the first timer corresponding to the first time period at a time t1 after the first message is successfully sent. And closing the radio frequency module of the first timer during the running period of the first timer, and not monitoring the first scheduling information until the first timer is finished. And starting a second timer corresponding to a second time period at t3 after the first timer is finished, starting a radio frequency module of the second timer during the running period of the second timer, and monitoring the first scheduling information. Alternatively, the starting time of the third time period in fig. 6d may be later than the time t0 and separated from the time t0 by one or more time slots/symbols, and the starting time of the second time period in fig. 6d may also be the time t2, without limitation.

In the following, with reference to the scenario shown in fig. 7 in which a user receives and sends a WeChat through a mobile phone, where a terminal is a mobile phone, a network device is a base station, the mobile phone is in an idle state, the mobile phone sends uplink data through a two-step random access process, the time for the upper layer of the base station to receive the uplink data and generate upper layer feedback information corresponding to the uplink data to the bottom layer of the base station to code and modulate the upper layer feedback information and send the upper layer feedback information is 200ms, and the transmission delay between the mobile phone and the base station is 50ms, for example, the monitoring method shown in fig. 5 is described.

As shown in fig. 7, the mobile phone is in an idle state and can receive the broadcast message sent by the base station.

And the base station sends a broadcast message, wherein the broadcast message comprises the relevant configuration of the first time period, the relevant configuration of the second time period and the monitoring parameters in the second time period. The related configuration of the first time period comprises the duration of the first time period, and the starting time and/or the ending time of the first time period, and the related configuration of the second time period comprises the duration of the second time period, and the starting time and/or the ending time of the second time period. The duration of the first time period may be set to 100ms and the duration of the second time period may be set to 100 ms.

The mobile phone monitors the broadcast message, acquires the related configuration of the first time period, the related configuration of the second time period and the monitoring parameters in the second time period from the broadcast message, and configures a first timer corresponding to the first time period and a second timer corresponding to the second time period according to the acquired information.

In a specific scenario, when a user sends a wechat message through a mobile phone, the wechat message sent by the user has only one number or one character, the data volume is small, the terminal device can not enter a connected state, and the wechat message with the small data volume is sent in a packet data sending mode in a non-connected state. At this time, the mobile phone generates a data message corresponding to the WeChat message, sends the msgA to the base station, carries the data message in the msgA, starts a first timer after sending the msgA, and does not monitor scheduling information for scheduling the msgB during the running period of the first timer.

The bottom layer of the base station receives the msgA, decodes and demodulates the msgA to obtain a data message, and sends the data message to the high layer of the base station, the high layer of the base station forwards the data message to a WeChat server, and the WeChat server can analyze the WeChat message and send high layer feedback information. The high layer of the base station acquires the high layer feedback information from the server, such as 'message sending success', and sends the high layer feedback information to the bottom layer of the base station, the bottom layer of the base station carries out coding modulation processing on the high layer feedback information to obtain downlink data, carries the downlink data and a response message of receiving msgA determined by the bottom layer of the base station on msgB, and sends scheduling information and msgB for scheduling msgB to the mobile phone.

And after the first timer is stopped, the mobile phone starts a second timer and starts to monitor and schedule the scheduling information of the msgB according to the monitoring parameters in the second time period. If the scheduling information of the scheduling msgB is monitored in the running period of the second timer, the monitoring is stopped, the msgB is received at the time-frequency resource position indicated by the scheduling information of the scheduling msgB, the high-level feedback information is acquired from the received msgB, and the received high-level feedback information is: the "message sending success" is presented to the user. Of course, the "successful message sending" presented in fig. 7 is only an example, and the message may not be displayed or the successful sending may be indicated by other display manners.

Compared with the existing monitoring method for monitoring the scheduling information for scheduling the msgB after the mobile phone sends the msgA, the existing monitoring method requires the mobile phone to occupy about 200ms of time to monitor the scheduling information for scheduling the msgB, whereas the time for monitoring the scheduling information of the method shown in fig. 7 is about 100ms, which shortens the monitoring time, lengthens the time for the mobile phone to be in a sleep state, and reduces the power consumption of the mobile phone.

The method shown in fig. 5 and 7 is to illustrate a method for monitoring scheduling information by a terminal in an idle state or an inactive state, for example, sending a response message of receiving a first message determined by a bottom layer of a network device and high-layer feedback information corresponding to uplink data determined by a high layer of the network device to the terminal. However, in practical applications, after the network device receives the first message including the uplink data, there may be three situations: in the first case, after receiving the first message including the uplink data, the network device happens to have a downlink service that requires the terminal to switch to the connected state, and at this time, the network device may send a response message, which is determined by the bottom layer of the network device and receives the first message, to the terminal as soon as possible, and send high-layer feedback information, which is determined by the high layer of the network device and corresponds to the uplink data, to the terminal as normal downlink data when the terminal switches to the connected state. And in the second situation, after the network equipment receives the first message comprising the uplink data, the response message of the first message received and determined by the bottom layer of the network equipment and the high-layer feedback information corresponding to the uplink data and determined by the high layer of the network equipment are included in the same downlink data and are sent to the terminal. And thirdly, after the network equipment receives the first message comprising the uplink data, firstly, sending a response message which is determined by the bottom layer of the network equipment and receives the first message to the terminal as soon as possible, then, scheduling high-layer feedback information which is determined by the high layer of the network equipment and corresponds to the uplink data to the terminal, and meanwhile, indicating the terminal to monitor scheduling information for scheduling the high-layer feedback information in a certain time period after monitoring the scheduling information after the response message is scheduled.

For a terminal, which condition is unknown for a network device to send downlink data, in order to ensure that the terminal can receive the downlink data sent by the network device when the terminal is in an idle state or an inactive state, and simultaneously reduce power consumption of the terminal for monitoring scheduling information used for scheduling the downlink data, an embodiment of the present application further provides a monitoring method, in which two time periods are set for the terminal, the terminal monitors scheduling information of response messages for bottom layer feedback of the scheduling network device in one time period, and monitors scheduling information of high layer feedback information for high layer feedback of the scheduling network device in another time period. In particular, the method may be as shown in fig. 8.

Fig. 8 is a monitoring method according to an embodiment of the present application, where the monitoring method is executed by a terminal, and the terminal is in an idle state or an inactive state. As shown in fig. 8, the method may include:

step 801, the terminal sends a first message to the network device.

The related description of the first message, and the execution process of step 801 may refer to step 501, such as: the first message is sent to the network device via msg3 or msgB or a configuration scheduling message, which are not described in detail.

The network device receives the first message, and executes step 802a or step 802b or step 803 c:

step 802 a: and the network equipment sends the first scheduling information and the first downlink data to the terminal.

The first downlink data in step 802a is different from the first downlink data in step 502, and the first downlink data in step 802a may include a response message determined by a bottom layer of the network device, where the response message may be used to indicate that the terminal network device receives the first message, and further may be used to indicate that the terminal switches to the connected state. In response to the terminal transmitting the first message, the network device may transmit the first downlink data to the terminal by using msg4 in the four-step random access procedure, or transmit the first downlink data to the terminal by using msgA in the two-step random access procedure, or transmit the first downlink data to the terminal by configuring a scheduling response, as described in the above-described manner (2.1) to (2.3).

If the network device sends the first scheduling information and the first downlink data to the terminal, the network device determines not to include the high-level feedback information corresponding to the uplink data determined by the high level of the network device and the response message determined by the bottom layer to the terminal, and is likely to send the high-level feedback information corresponding to the uplink data to the terminal when the terminal is switched to the connected state, and after monitoring the first scheduling information, the terminal does not need to monitor the scheduling information in an idle state or an inactive state. On the contrary, if the network device wants to send the higher layer feedback information corresponding to the uplink data to the terminal after sending the first uplink data including the response message, the network device may perform step 802 b.

Step 802 b: the network equipment sends first scheduling information and first downlink data to the terminal, and sends second scheduling information and second downlink data to the terminal.

The second scheduling information may be used to schedule second downlink data. The sending, by the network device, the second scheduling information and the second downlink data to the terminal may include: and the network equipment sends second scheduling information to the terminal through the PDCCH and sends second downlink data to the terminal at the time-frequency resource position indicated by the second scheduling information.

The first downlink data in step 802b is different from the first downlink data in step 502 and step 802a, and the first downlink data in step 802b may include a response message determined by the bottom layer of the network device and indication information. The response message may be used to indicate that the terminal network device receives the first message, and further may be used to indicate that the terminal switches to the connected state. The indication information may be used to instruct the terminal to monitor the second scheduling information in a fifth time period after monitoring the first scheduling information, and may also be used to instruct monitoring parameters and other information in the fifth time period, such as: the duration of the fifth time period, the start time and/or the end time of the fifth time period.

In response to the terminal transmitting the first message, the network device may transmit the first downlink data to the terminal by using msg4 in the four-step random access procedure, or transmit the first downlink data to the terminal by using msgA in the two-step random access procedure, or transmit the first downlink data to the terminal by configuring a scheduling response, as described in the above-described manner (2.1) to (2.3).

In step 802b, the network device decouples the response message determined by the lower layer of the network device from the higher layer feedback information determined by the higher layer of the network device. The time when the network device transmits the first scheduling information is earlier than the time when the network device transmits the second scheduling information. For example, the time for the network device to transmit the first scheduling information may be determined according to the time for the network device to determine the response message at the bottom layer, and the time for the network device to transmit the second scheduling information may be determined according to the time for the network device to determine the high layer feedback information to the bottom layer of the network device to receive and process the high layer feedback information at the top layer.

Step 802 c: the network equipment does not send the first scheduling information and the first downlink data to the terminal, and sends the second scheduling information and the second downlink data to the terminal.

The second downlink data in step 802c and the second downlink data in step 802b include different contents, and the second downlink data in step 802c may include not only the high-layer feedback information corresponding to the uplink data, but also a response message determined by the bottom layer of the network device. In response to the terminal sending the first message, the network device may send the second downlink data to the terminal by using msg4 in the four-step random access procedure, or send the second downlink data to the terminal by using msgA in the two-step random access procedure, or send the second downlink data to the terminal by configuring a scheduling response, in the manners described in the foregoing manners (2.1) to (2.3).

That is, in step 802c, the network device includes the response message determined by the lower layer of the network device and the higher layer feedback information determined by the higher layer of the network device in the second downlink data, and sends the second downlink data to the terminal. At this time, the time when the network device sends the second scheduling information may be determined according to the time when the upper layer of the network device determines that the upper layer feedback information is received by the bottom layer of the network device and processes the upper layer feedback information.

Step 803: and the terminal monitors the first scheduling information in a fourth time period after the terminal sends the first message.

The fourth time period may be used to limit a time period for the terminal to monitor the first scheduling information. The fourth time period corresponds to the time when the bottom layer of the network device feeds back the response message to the terminal. The duration of the fourth time period, the starting time and/or the ending time of the fourth time period may be determined by the terminal according to the network device configuration, such as: the network device broadcasts the duration of the fourth time period, and the starting time and/or the ending time of the fourth time period in the broadcast message, and the terminal receives the broadcast message and acquires the duration of the fourth time period, and the starting time and/or the ending time of the fourth time period from the broadcast message. Alternatively, the duration of the fourth time period, the start time and/or the end time of the fourth time period may also be predefined by the protocol, without limitation.

For example, the terminal may configure a fourth timer according to the duration of the fourth time period, the start time and/or the end time of the fourth time period, the duration of the fourth timer is equal to the duration of the fourth time period, the start time of the fourth timer corresponds to the start time of the fourth time period, the fourth timer is started after the terminal sends the first message, and the first scheduling information is monitored during the validity/operation period of the fourth timer.

Wherein the starting time of the fourth time period is related to the ending time of the first message. In one possible design, the starting time of the fourth time period may be equal to or later than the end time of the first message, such as: the starting time of the fourth period may be an end time of first transmitting the first message, or the starting time of the fourth period may be a time domain position spaced several slots/symbols from the end time of first transmitting the first message after the end time of first transmitting the first message. As shown in fig. 9a, the starting time of the fourth period of time is the end time t0 of the sending of the first message.

In yet another possible design, to ensure that the first message is successfully transmitted, the starting time of the fourth time period may be set equal to or later than the time at which the first message is determined to be successfully transmitted. For example, the starting time of the fourth time period may be a time when the first message is determined to be successfully transmitted, or the starting time of the fourth time period may be a time domain position separated from the time when the first message is determined to be successfully transmitted by several slots/symbols after the time when the first message is determined to be successfully transmitted. As shown in fig. 9b, the starting time of the fourth period of time is time t1 at which the first message is determined to be successfully transmitted.

Wherein the terminal may determine whether the first message was successfully transmitted by monitoring information scheduling retransmission of the first message for a fourth time period. The description of the fourth time period and the specific implementation process for determining whether the first message is successfully sent refer to the description in step 403, which is not repeated herein.

For example, the terminal monitoring the first scheduling information during the fourth time period may include: and the terminal determines the monitoring parameters in the fourth time period and monitors the first scheduling information according to the monitoring parameters in the fourth time period.

Wherein the monitoring parameters during the fourth time period may include: and one or more information of the configuration of the search space, the configuration of the CORESET and the RNTI corresponding to the first scheduling information. The configuration of the search space may include one or more of a monitoring period of the search space, a DCI format of downlink control information to be monitored, a number of candidates to be monitored, and an aggregation level to be monitored. The related definition of each parameter may refer to the existing description, and the manner in which the terminal monitors the first scheduling information according to the monitoring parameter of the fourth time period may refer to the existing description, which is not repeated.

The monitoring parameters in the fourth time period may also be determined by the terminal according to the configuration of the network device, such as: and the network equipment broadcasts the monitoring parameters in the fourth time period in the broadcast message, and the terminal receives the broadcast message broadcasted by the network equipment and acquires the monitoring parameters in the fourth time period from the broadcast message.

It should be noted that, in the embodiments of the present application, the monitoring parameter in the fourth time period, the time length of the fourth time period, and the start time and/or the end time of the fourth time period may be configured to the terminal in the same broadcast message, or may be configured to the terminal in different broadcast messages, without limitation.

Step 804: and the terminal monitors the second scheduling information in a fifth time period after the fourth time period.

For example, when the terminal determines that the first scheduling information is not monitored in the fourth time period, the terminal monitors the second scheduling information in a fifth time period after the fourth time period; or the terminal determines that the first downlink data comprises the indication information, and when the indication information is used for indicating that the second scheduling information is monitored in the fifth time period, the second scheduling information is monitored in the fifth time period according to the indication information. And if the terminal determines that the first scheduling information is monitored in the fourth time period and does not include the indication information in the first downlink data received according to the time-frequency resource position indicated by the first scheduling information, monitoring the second scheduling information in a fifth time period after the fourth time period.

The fifth time period may be used to limit a duration for the terminal to monitor the second scheduling information. And the fifth time period corresponds to the time when the high layer of the network equipment sends the high layer feedback information to the terminal. In one possible design, the duration of the fifth time period, and the start time and/or the end time of the fifth time period may be determined by the terminal according to the network device configuration, such as: the network device broadcasts the duration of the fifth time period, the starting time and/or the ending time of the fifth time period in the broadcast message, the terminal receives the broadcast message, and the duration of the fifth time period, the starting time and/or the ending time of the fifth time period are obtained from the broadcast message. In yet another possible design, the duration of the fifth time period, and the start time and/or the end time of the fifth time period may be included in the indication information configured to the terminal. In another possible design, the duration of the fifth time period, and the start time and/or the end time of the fifth time period may also be predefined by a protocol, without limitation.

For example, the terminal may configure a fifth timer according to the duration of the fifth time period, the start time and/or the end time of the fifth time period, where the duration of the fifth timer is equal to the duration of the fifth time period, the start time of the fifth timer corresponds to the start time of the fifth time period, start the fifth timer after the terminal sends the first message, and monitor the second scheduling information during the valid period/running period of the fifth timer.

Wherein the start time of the fifth period of time may be equal to or later than the end time of the fourth period of time. Such as: the start time of the fifth period may be the end time of the fourth period or the start time of the fifth period may be a time domain location a few slots/symbols after the end time of the fourth period, spaced from the end time of the fourth period.

For example, the monitoring, by the terminal, the second scheduling information during the fifth time period may include: and the terminal determines the monitoring parameters in the fifth time period and monitors the second scheduling information according to the monitoring parameters in the fifth time period.

Wherein the monitoring parameters in the fifth time period may include: and one or more information of RNTI corresponding to the configuration of the search space, the CORESET configuration and the second scheduling information. The configuration of the search space may include one or more of a monitoring period of the search space, a DCI format of downlink control information to be monitored, a number of candidates to be monitored, and an aggregation level to be monitored. The related definition of each parameter may refer to the existing description, and the manner in which the terminal monitors the second scheduling information according to the monitoring parameter of the fifth time period may refer to the existing description, which is not repeated.

It should be noted that, in order to reduce the power consumption of the terminal, the monitoring period of the search space corresponding to the fifth time period may be set to be greater than or equal to the monitoring period of the search space corresponding to the fourth time period.

The monitoring parameters in the fifth time period may also be determined by the terminal according to the configuration of the network device, such as: the network equipment broadcasts the monitoring parameters in the fifth time period in the broadcast message, and the terminal receives the broadcast message broadcasted by the network equipment and acquires the monitoring parameters in the fifth time period from the broadcast message; or, the network device includes the monitoring parameter in the fifth time period in the indication information and configures the monitoring parameter to the terminal.

It should be noted that, in each embodiment of the present application, when the monitoring parameter in the fifth time period, the duration of the fifth time period, and the start time and/or the end time of the fifth time period are configured to the terminal through the broadcast message, the monitoring parameter in the fifth time period, the duration of the fifth time period, and the start time and/or the end time of the fifth time period may be configured to the terminal in the same broadcast message, or may be configured to the terminal in different broadcast messages, which is not limited.

Further, to avoid that the terminal monitors the second scheduling information indefinitely, the method shown in fig. 8 may further include: and when the condition for stopping monitoring is met, stopping monitoring the second scheduling information.

The condition for stopping monitoring may refer to step 504 above, and may include that the second downlink data is successfully received within a fifth time period; alternatively, the fifth time period ends.

For example, if the terminal monitors the second scheduling information in the fifth time period, the second downlink data is received according to the time-frequency resource position indicated by the second scheduling information, and the second downlink data is successfully received through verification, the monitoring of the second scheduling information is stopped, so that the energy consumption of the terminal is saved. Or, if the terminal has not monitored the second scheduling information in the fifth time period, the terminal stops monitoring the second scheduling information when the fifth time period is over. Or, the terminal monitors the second scheduling information in the fifth time period, but does not receive the second downlink data according to the time-frequency position information indicated by the second scheduling information in the fifth time period, and the terminal may stop monitoring the second scheduling information when the fifth time period ends.

By applying the method shown in fig. 8, after the terminal sends the uplink data, the terminal may monitor the first scheduling information in the fourth time period, and monitor the second scheduling information in the fifth time period, that is, set a specific time period, and monitor the scheduling information in the specific time period, thereby avoiding the problem of large power consumption caused by monitoring the scheduling information indefinitely. Meanwhile, in the method of the seventh aspect, by setting two time periods for monitoring the scheduling information, the terminal monitors the scheduling information for scheduling the downlink data in the first and second time periods, and the accuracy of receiving the downlink data is ensured under the condition that the network device flexibly sends the downlink data.

For example, as shown in fig. 9a, a fourth period of time is set: t 0-t 1, fifth time period: time t2 to time t 3. And starting a fourth timer corresponding to a fourth time period at a time t0 after the terminal sends the first message to the network device, starting a radio frequency module of the terminal during the running period of the fourth timer, and monitoring the first scheduling information until the fourth timer is finished. And if the first scheduling information is monitored during the running period of the fourth timer and the first downlink data is received according to the first scheduling information, not monitoring the second scheduling information in the fifth time period.

For another example, as shown in fig. 9b, a fourth time period is set: t 0-t 1, fifth time period: time t2 to time t 3. And starting a fourth timer corresponding to a fourth time period at a time t0 after the terminal sends the first message to the network device, starting a radio frequency module of the terminal during the running period of the fourth timer, and monitoring the first scheduling information until the fourth timer is finished. If the first scheduling information is not monitored during the running period of the fourth timer, starting a fifth timer corresponding to a fifth time period at a time t2 after the fourth timer is finished, and starting a radio frequency module of the fifth timer during the running period of the fifth timer to monitor the second scheduling information.

For another example, as shown in fig. 9c, a fourth period of time is set: t 0-t 1, fifth time period: time t2 to time t 3. And starting a fourth timer corresponding to a fourth time period at a time t0 after the terminal sends the first message to the network device, starting a radio frequency module of the terminal during the running period of the fourth timer, and monitoring the first scheduling information until the fourth timer is finished. If the first scheduling information is monitored during the running period of the fourth timer, and the first downlink data is received according to the first scheduling information, and the first downlink data includes indication information for indicating the terminal to monitor the second scheduling information in the fifth time period, the terminal starts a fifth timer corresponding to the fifth time period at the time t2 according to the indication information, and starts a radio frequency module of the terminal during the running period of the fifth timer to monitor the second scheduling information.

In the following, referring to the scenario shown in fig. 10 in which a user receives and sends a WeChat through a mobile phone, where a terminal is a mobile phone and a network device is a base station, the mobile phone is in an idle state, the mobile phone sends uplink data through a two-step random access process, after receiving the uplink data, a high-level layer of the base station first feeds back a response message determined by a bottom layer to the terminal as soon as possible, and then generates high-level feedback information corresponding to the uplink data, and sends the high-level feedback information to the terminal, which is taken as an example, to describe the monitoring method shown in fig. 8.

As shown in fig. 10, the mobile phone is in an idle state and can receive the broadcast message sent by the base station.

And the base station sends a broadcast message, wherein the broadcast message comprises the relevant configuration of the fourth time period, the relevant configuration of the fifth time period and the monitoring parameters in the fifth time period. The relevant configuration of the fourth time period comprises the duration of the fourth time period, the starting time and/or the ending time of the fourth time period, and the relevant configuration of the fifth time period comprises the duration of the fifth time period, the starting time and/or the ending time of the fifth time period. The duration of the fourth period of time may be set to 50ms and the duration of the fifth period of time may be set to 100 ms.

The mobile phone monitors the broadcast message, acquires the related configuration of the fourth time period, the related configuration of the fifth time period and the monitoring parameter in the fifth time period from the broadcast message, and configures a fourth timer corresponding to the fourth time period and a fifth timer corresponding to the fifth time period according to the acquired information.

In a specific scenario, when a user sends a wechat message through a mobile phone, the wechat message sent by the user has only one number or one character, the data volume is small, the terminal device can not enter a connected state, and the wechat message with the small data volume is sent in a packet data sending mode in a non-connected state. At this time, the mobile phone generates a data message corresponding to the WeChat message, sends the msgA to the base station, the msgA carries the data message, starts a fourth timer after sending the msgA, and monitors scheduling information for scheduling the msgB during the running period of the fourth timer.

When the msgA is received by the bottom layer of the base station, a response message and indication information are fed back to the terminal, for example: and carrying the response message and the indication information in the msgB, and sending scheduling information for scheduling the msgB and the msgB to the mobile phone. And meanwhile, the msgA is decoded and demodulated to obtain a data message, and the data message is sent to the high layer of the base station, the high layer of the base station forwards the data message to a WeChat server, and the WeChat server can analyze the WeChat message and send high layer feedback information. The high layer of the base station acquires the high layer feedback information from the server, if the information is successfully sent, the high layer feedback information is sent to the bottom layer of the base station, the bottom layer of the base station carries out coding modulation processing on the high layer feedback information to obtain downlink data, and the scheduling information used for scheduling the downlink data and the downlink data are sent to the mobile phone.

And the mobile phone monitors scheduling information for scheduling the msgB during the running period of the fourth timer, receives indication information at a time-frequency resource position indicated by the scheduling information for scheduling the msgB, starts a fifth timer according to the indication information, and starts to monitor and schedule scheduling information of downlink data according to the monitoring parameters in a fifth time period. If the scheduling information of the downlink data is monitored during the operation period of the fifth timer, the monitoring is stopped, the downlink data is received at the time-frequency resource position indicated by the scheduling information of the downlink data, the high-level feedback information is obtained from the received downlink data, and the received high-level feedback information is processed by the following steps: the "message sending success" is presented to the user. Of course, the "successful message sending" presented in fig. 10 is only an example, and the message may not be displayed or the successful sending may be indicated by other display manners.

Compared with the existing monitoring method for monitoring the scheduling information for scheduling msgB after the mobile phone sends msgA, the existing monitoring method requires the mobile phone to occupy about 200ms to monitor the scheduling information for scheduling including the response message and the high-level feedback information, whereas the monitoring method of the method shown in fig. 10 includes two-time monitoring, and the total time for monitoring the scheduling information twice is about 150ms, which shortens the monitoring time and reduces the power consumption of the mobile phone.

Further, in the monitoring methods shown in fig. 5 to 10, in order to better reduce the power consumption of the terminal, the search spaces for scheduling information for scheduling packet data may be all set to be different from the first search space, such as: the number of search spaces for scheduling information used for scheduling packet data is reduced, the number of blind tests is reduced, and the power consumption of the terminal is reduced. Or, the monitoring period of the search space for scheduling information of the packet data is set to be different from the first search space, such as: the monitoring period of the search space for scheduling information of the packet data is set to be longer than 5 slots (slots)/10 slots, so that the frequency of the terminal for monitoring the scheduling information is reduced, and the power consumption of the terminal is further reduced.

The first search space may be a search space for monitoring scheduling information for scheduling non-packet data. The first search space may be referred to as a random-access search space (ra-search space). The search space for scheduling information of the packet data may be referred to as a random-access search space packet data (ra-search space small data) or a random-access search space for the packet data, and may also be referred to as a dedicated search space, without limitation.

For example, when the first downlink data is packet data, the search space of the first scheduling information may be set to be the same as the first search space, and the monitoring period of the search space of the first scheduling information is different from the monitoring period of the first search space; alternatively, the search space of the first scheduling information is set to be different from the first search space. When the second downlink data is packet data, the search space of the second scheduling information may be set to be the same as the first search space, and the monitoring period of the search space of the second scheduling information is different from the monitoring period of the first search space; alternatively, the search space of the second scheduling information is set to be different from the first search space.

In the method shown in fig. 5, the search space of the first scheduling information may refer to a search space in the second time period, and the monitoring period of the search space of the first scheduling information may refer to a monitoring period of the search space in the second time period.

In the method shown in fig. 8, the search space of the first scheduling information may refer to a search space in a fourth period, and the monitoring period of the search space of the first scheduling information may refer to a monitoring period of the search space in the fourth period. The search space of the second scheduling information may refer to a search space in a fifth time period, and the monitoring period of the search space of the second scheduling information may refer to a monitoring period of the search space in the fifth time period.

For example, in a four-step random access procedure, a search space for scheduling information of packet data is referred to as a dedicated search space, as shown in fig. 11a, a terminal may monitor scheduling information for scheduling msg2 in a random access search space (ra-search space), monitor scheduling information for scheduling msg3 in the ra-search space, and after the terminal has transmitted msg3 carrying packet data, the terminal may switch to the dedicated search space to monitor scheduling information for scheduling msg 4. Alternatively, as shown in fig. 11b, the terminal may directly transmit msg1 using dedicated preamble sequence resources and start monitoring scheduling information for scheduling msg2/msg3/msg4 within the dedicated search space after transmitting msg 1.

For another example, in a four-step random access procedure, a search space for scheduling information of packet data is referred to as a dedicated search space, as shown in fig. 11c, a terminal may monitor scheduling information for scheduling msg2 in an ra-search space by using a monitoring period of the ra-search space, monitor scheduling information for scheduling msg3 in the ra-search space by using a monitoring period of the ra-search space, and after the terminal has finished transmitting msg3 carrying packet data, the terminal may switch to the dedicated search space and monitor scheduling information for scheduling msg4 by using the monitoring period of the dedicated search space. Alternatively, as shown in fig. 11d, the terminal may directly transmit msg1 using dedicated preamble sequence resources and start monitoring scheduling information for scheduling msg2/msg3/msg4 within the dedicated search space using a monitoring period of the dedicated search space after transmitting msg 1.
