Abstract

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 the first downlink data after the first time period, and stops monitoring the first scheduling information when a 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 device.
Background
Currently, when a terminal is in an idle state or a non-active (inactive) state, if the terminal needs to send uplink service data to a network device, the terminal needs to initiate a random access procedure, and send the uplink service data to the network device after switching from the idle/inactive state to a connected (connected) state. If the uplink service data is packet data, the data size is smaller, and at this time, sending less data also needs to initiate a complete random access procedure, so that signaling overhead and power consumption of the terminal are increased.
In order to reduce signaling overhead and power consumption of the terminal, the terminal may send packet data to the network device during random access. 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 that the packet data is sent, and high layer feedback information including the network device.
However, the feedback speed of the lower layer acknowledgement message is generally fast, for example, within 5ms, and the generation of the higher layer feedback information is generally slow, which may require more than 200 ms. If the network device determines that the higher layer feedback information is sent to the terminal, the network device needs to wait until the higher layer feedback information is generated and then send a corresponding physical downlink control channel (physical downlink control channel, PDCCH) and a corresponding message for scheduling, and the interval time is longer, so that the terminal monitors the corresponding PDCCH in a preconfigured search space for a longer duration monitoring time, and the power consumption of the terminal is increased.

Detailed Description
Before describing the embodiments of the present application, some terms related to the embodiments of the present application will be explained:
the connected state may be referred to as a radio resource control connected (radio resource control connected, RRC-connected) state. In the connected state, the terminal is connected with a network device (such as an access network device), and data transmission is performed between the terminal and the network device (such as: the terminal may receive downlink data from the network device or send uplink data to the network device.
The idle state may be referred to as a radio resource control idle (radio resource control idle, RRC-idle) state. In an idle state, the terminal is not connected to the network device (e.g., the access network device), the network device does not know whether the terminal is within the coverage area of the network device, and the terminal can receive one or more of paging (paging) messages, synchronization signals, broadcast messages, or system information from the network device, but cannot perform data transmission such as voice call, large data volume internet surfing, etc. with the network device.
The inactive (inactive) state may be referred to as a radio resource control inactive (radio resource control inactive, RRC-inactive) state. In the non-connected state, the terminal and the network device (for example, the access network device) are not connected, but the context of the terminal can be stored in the network device, and the terminal can receive one or more of paging messages, synchronous signals, broadcast messages or system information from the network device, but cannot perform data transmission such as voice call, large data volume internet surfing with the network device.
Wherein the idle state or inactive state may be referred to as a non-connected state or dormant state.
In order to reduce the 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 (configuration grant, CG) procedure. The random access procedure may include a four-step random access procedure and a two-step random access procedure. The small packet data (small data) may refer to data having a bit number equal to or less than a preset value, which is set as needed. By way of example, the packet data may be a few bits (bits) of data, tens or hundreds of bits of data, and the preset value may be 100 bits, 10 bits, or the like, for example.
Referring to fig. 1a, a four-step random access procedure may include: and (1) the terminal sends a first message (msg 1) to the network equipment to inform the network equipment of a random access request. Wherein the first message may also be referred to as a random access preamble sequence (random access preamble). After the network device receives msg1, step (2), the network device sends a random access response to the terminal, where the random access response may also be called a second message (msg 2). And (3) after receiving the random access response, the terminal sends a third message (msg 3) to the network equipment, wherein the msg3 can comprise small packet data and other information. And (4) the network equipment sends a fourth message (msg 4) 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 corresponding to the small packet data determined by the high-layer of the network equipment. 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 random access preamble to the network device in the first step, the preamble (preamble sequence) used by the terminal is randomly selected from an optional preamble set. msg2/msg3/msg4 are all required to be scheduled to a terminal by a network device through a physical downlink control channel (physical downlink control channel, PDCCH), for example: before transmitting msg2/msg3/msg4, the network device may transmit a PDCCH for scheduling msg2/msg3/msg4, and transmit msg2/msg3/msg4 on a time-frequency resource location indicated by the PDCCH.
Referring to fig. 1b, for a two-step random access procedure, it may include: step (1), the terminal sends msgA to the network device, where the msgA may include a preamble, and may further include packet data and other information. And (2) the network equipment receives the msgA and replies the 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 corresponding to the small packet data determined by the high-layer of the network equipment. 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 the msgA to the network device, the preamble used by the terminal is randomly selected from an optional preamble set. The following msgB all require the network device to schedule to the terminal through PDCCH, for example: before sending the msgB, the network device may send a PDCCH for scheduling the msgB, and send the msgB on a time-frequency resource location indicated by the PDCCH.
Referring to fig. 1c, for CG procedure, may include: and (1) the network equipment sends uplink resource configuration information to the terminal, and configures uplink resources for sending uplink data for the terminal. And (2) the terminal sends a configuration scheduling message comprising small packet data to the network equipment on the uplink resource configured by the network equipment. And (3) the network equipment receives the small 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 corresponding to the small packet data determined by the high-layer of the network equipment. 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 (transmission control protocol, TCP)/internet protocol (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 a terminal may be referred to as a higher 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 a network device may be referred to as a higher 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 packet data is used for packaging the uplink data and transmitting the uplink data to a physical layer of the terminal, and the physical layer of the terminal codes and modulates the uplink data and then transmits the uplink data 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 "physical layer response message" to the physical layer of the terminal, so that the terminal knows that the uplink data packet is correctly transmitted in the physical layer, and meanwhile, the physical layer of the network device can decode and demodulate the uplink data and transmit the decoded and demodulated uplink data to the TCP/IP layer of the network device. After the TCP/IP layer of the network device receives the uplink data, a high-layer feedback information of the TCP/IP layer is generated and fed back to the terminal through the physical layer of the network device (as shown by a dotted line in fig. 2). Because the TCP/IP layer of the network device generates the higher layer feedback information and the time for transmitting the higher layer feedback information is relatively long, usually 200ms, after the terminal transmits the packet data, the terminal receives one higher layer feedback information after a relatively long certain time. At this time, if the terminal monitors the scheduling information for scheduling the higher layer feedback information for a long period of time, the power consumption of the terminal is increased.
In order to solve the problem of larger power consumption of a terminal, the embodiment of the application provides a monitoring method for reducing the power consumption of the terminal for monitoring scheduling information. The following describes a 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 by the embodiment of the application can be used for any system of a fourth generation (4th generation,4G) system, a long term evolution (long term evolution, LTE) system, a fifth generation (5th generation,5G) system, a New Radio (NR) system, an NR-vehicle-to-anything communication (V2X) system and an Internet of things system, and can be also suitable for other next generation communication systems and the like without limitation. The following describes a monitoring method provided by the embodiment of the present application, taking the communication system shown in fig. 3 as an example.

The following describes a monitoring method provided by the embodiment of the present application, taking a device for implementing a function of a terminal as an example of the terminal.
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 scheduling information for scheduling msg4 or msgB or configuring the scheduling response may not be monitored for a period of time, and then monitoring of the scheduling information may be started. Or, setting two time periods, after the terminal sends uplink data to the network equipment through the msg 3/msgA/configuration scheduling message, monitoring the scheduling information for scheduling msg4 or msgB or configuring scheduling response in the first time period, wherein the scheduling information is monitored in the first time period, and the scheduling information is not monitored in the second time period; or, an indication is detected in the first time period, the indication indicates whether the terminal is to monitor in the second time period, and the terminal monitors in the second time period according to the indication.

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 carries out code modulation on the received data to obtain uplink data. The related descriptions of the higher layer of the terminal and the lower layer of the terminal may be described with reference to fig. 2, and the process of generating data by the higher layer of the terminal and the process of code modulating data by the lower layer of the terminal may be described with reference to the prior art, which are not repeated.
In the embodiments of the present application, uplink data and downlink data are relative concepts, and uplink data may refer to data sent from a terminal to a network device, and downlink data may refer to data sent from a network device to a terminal.
For example, the terminal may send the first message to the network device through a four-step random access procedure or a two-step random access procedure or a configuration scheduling procedure, where the sending manner is described with reference to the modes (1.1) to (1.3):
mode (1.1), terminal sends the first message to the network equipment through msg3 in the four-step random access process.
For example, the terminal may include uplink data in the first message, include the first message in msg3, and send the first message to the network device; alternatively, the upstream data is included in the first message, which is sent as msg3 to the network device, at which point the first message may be referred to as msg3.
And (2) the mode (1.2) and the terminal send a first message to the network equipment through the msgA in the two-step random access process.
For example, the terminal may include uplink data in the first message, include the first message in the msgA, and send the first message to the network device; alternatively, the terminal includes uplink data in the first message, and transmits the first message as msgA to the network device, where the first message may be referred to as msgA.
And (3) the mode (1.3) and the terminal send a first message to the network equipment through the configuration scheduling message.
For example, the terminal may include the first message in the first message included in the uplink data, and send the configuration scheduling message to the network device on the uplink transmission resource preconfigured to the terminal by the network device; alternatively, the terminal may include the uplink data in the first message, and send the first message to the network device on the uplink transmission resource preconfigured to the terminal by the network device, where the first message may be referred to as a configuration scheduling message.
The embodiment of the application does not limit the naming of the configuration scheduling message, and the configuration scheduling message can be named as a pre-configuration message, a pre-set message or other names of messages, without limitation.
The data volume transmitted by the three transmission modes is limited, for example: data with a smaller data amount is transmitted in order to ensure the reliability of data transmission. Illustratively, before executing 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, for example: the terminal starts a radio frequency module of the terminal and sends a first message to the network equipment by adopting any one of the modes (1.1) to (1.3) through the radio frequency module. 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 amount of the uplink data is smaller than the preset value, the uplink data is indicated to be small packet data, otherwise, if the data amount of the uplink data is larger than or equal to the preset value, the uplink data is indicated to be non-small packet data. Specifically, the preset value may be specified in the standard, or may be configured by broadcasting a system message of the network device.
Step 502: the network device receives the first message and sends first scheduling information and first downlink data to the terminal.
The first scheduling information may be used to schedule the first downlink data. The network device sending the first scheduling information to the terminal may include: and the network equipment sends the first scheduling information to the terminal through the PDCCH, and sends the first downlink data to the terminal at the time-frequency resource position indicated by the first scheduling information.
The first downlink data may be high-layer feedback information corresponding to the uplink data, and the first downlink data may be packet data, that is, the data size 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 device decodes and demodulates the uplink data included in the first message and sends the decoded and demodulated uplink data to the high layer of the network device; after receiving data sent by a bottom layer of the network equipment, a high layer of the network equipment generates high layer feedback information corresponding to the data, and sends the generated high layer feedback information to the bottom layer of the network equipment, and the bottom layer of the network equipment carries out code modulation on the high layer feedback information to obtain first downlink data.
The related descriptions of the upper layer of the network device and the lower layer of the network device may be described with reference to fig. 2, and the process of generating the upper layer feedback information by the upper layer of the network device and the process of performing code modulation on the upper layer feedback information by the lower layer of the network device may be described with reference to the prior art, which are not repeated.
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 modes (2.1) to (2.3):
and (2.1) the mode and the network equipment send the first downlink data to the terminal through msg4 in the four-step random access process.
And (2.2) the mode and the network equipment send the first downlink data to the terminal through the msgB in the two-step random access process.
And (2.3) the mode and the network equipment send the first downlink data to the terminal through the configuration scheduling response.
In the mode (2.3), the configuration scheduling response may further include, in addition to the first downlink data, an underlying acknowledgement message and other information included in the existing configuration scheduling response, which indicates that the network device receives the first message, without limitation.
The embodiment of the application does not limit the naming of the configuration scheduling response, and the configuration scheduling response can be named as pre-configuration information or information with other names, and is not limited.
The scheduling information may be, for example, PDCCH or others. 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: the terminal does not monitor the first scheduling information in a first time period after the first message is sent.
Wherein the first time period may be used to define a time period during 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, the starting time and/or the ending time of the first time period are pre-defined by the protocol, and are not limited.
Taking the duration of the first time period, the starting time and/or the ending time of the first time period as an example, the network device may pre-configure the duration of the first time period, the starting time and/or the ending time of the first time period to the terminal, the terminal may receive a broadcast message from the network device, where the broadcast message includes relevant configurations such as the duration of the first time period, the starting time and/or the ending time of the first time period, and the terminal obtains the duration of the first time period, the starting time and/or the ending time of the first time period from the broadcast message.
The duration of the first period of time may be set as needed. For example, the first time period may be determined according to a time when the higher layer of the network device generates the higher layer feedback information, a time when the lower layer of the network device performs code modulation on the higher layer feedback information, for example: the duration of the first time period may be set to be less than or equal to a sum of a time when the higher layer of the network device generates the higher layer feedback information and a time when the lower layer of the network device code modulates the higher layer feedback information.
For example, the terminal may configure a first timer (timing) according to a duration of the first period, a start time and/or an end time of the first period, where the duration of the first timer is equal to the duration of the first period, and a start time of the first timer corresponds to the start time of the first period, and after the terminal sends the first message, the first timer is started, and the first scheduling information is not monitored during a validity period/an operation period of the first timer. In each embodiment of the present application, the terminal not monitoring the first scheduling information may refer to a function that the terminal turns off its own radio frequency module and stops transmitting and receiving data/information.
Wherein the starting time of the first time period is related to the ending time of the sending of the first message. In one possible design, the start time of the first time period may be set equal to or later than the end time of the first message being sent for the first time, such as: the starting time of the first time period may be the ending time of the first message being sent for the first time, or the starting time of the first time period may be a time domain position separated from the ending time of the first message being sent for the first time by a few time slots/symbols after the ending time of the first message being sent for the first time. As shown in fig. 6a to 6b, the start time of the first period is the end time t0 of the transmission of the first message.
In yet another possible design, to ensure that the first message is successfully sent, the starting time of the first time period may be set equal to or later than the time at which the successful sending of the first message is determined. For example, the starting time of the first time period may be a time at which 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 at which the first message is determined to be successfully transmitted by a few slots/symbols after the time at which the first message is determined to be successfully transmitted. For example, as shown in fig. 6d, the starting time of the first period is time t1 when it is determined that the first message was successfully transmitted.
In the embodiment of the application, the terminal can monitor the information for scheduling the retransmission of the first message in a third time period after the first message is transmitted for the first time, if the information for scheduling the retransmission of the first message is not received in the third time period, the terminal determines that the first message is successfully transmitted, otherwise, if the information for scheduling the retransmission of the first message is monitored, the terminal retransmits the first message to the network equipment according to the information for scheduling the retransmission of the first message, and starts the first time period after retransmitting the first message. The information of the first message retransmission may be a first message retransmission indication, which may indicate that the terminal resends the first message to the network device.
The duration of the third time period, the starting time and/or the ending 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 the protocol.
For example, the terminal may configure a third timer according to a duration of the third time period, a start time and/or an end time of the third time period, where the duration of the third timer is equal to the duration of the third time period, a 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 during a validity period/an operation 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 first sending 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 start time of the third period is the end time t0 when the first message is first transmitted.
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, a first time period may be named a first time window, a second time period may be named a second time window, a third time period may be named a third time window, a fourth time period may be named a fourth time window, a fifth time period may be named a fifth time window, etc.
In addition, each timer described in the embodiments of the present application may be replaced by a counter, where the product of the count number of the counter and the time length of each count is equal to the 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 the first time period, monitoring the first scheduling information.
The first scheduling information may be used to schedule the first downlink data. The description of the first scheduling information and the first downlink data may be referred to in step 502, and will not be repeated.
In one possible design, after the first period of time passes, the terminal starts its own radio frequency module, for example, at the end time of the first period of time, monitors the first scheduling information, or starts its own radio frequency module at the ith time slot/symbol after the end time of the first period of time, 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 at the end of the first period, at which time the time to end monitoring the first scheduling information is not specified.
In another possible design, a second time period is set after the first time period, the terminal starts a radio frequency module of the terminal in the second time period, monitors the first scheduling information, namely, divides the first scheduling information into a time period for monitoring, monitors the first scheduling information in the time period, and saves the power consumption of the terminal. For example, as shown in any one of fig. 6b to 6d, the terminal sets a second period after the end of the first period, and monitors the first scheduling information during the second period.
The second time period may be used to limit a duration of monitoring the first scheduling information by the terminal. 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, for example: the network equipment 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, 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 starting time of the second time period may be the ending time of the first time period or the starting time of the second time period may be a time domain position separated from the ending time of the first time period by a few slots/symbols after the ending time of the first time period. For example, as shown in any one of fig. 6b to 6d, the start time of the second period is a time-domain position at which there is a time interval between the end time of the first period and the end time of the first period.
For example, the terminal monitoring the first scheduling information in the second period of time may include: 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 monitored parameters within the second time period may include: configuration of a search space, CORESET configuration, and RNTI corresponding to the first scheduling information. The configuration of the search space may include one or more of information of a monitoring period of the search space, a downlink control information DCI format to be monitored, a number of candidates to be monitored, and an aggregation level to be monitored. The relevant 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 period of time may also be determined by the terminal according to the network device configuration, for example: the network device broadcasts the monitoring parameters in the second time period in the broadcast message, the terminal receives the broadcast message broadcast by the network device, and the monitoring parameters in the second time period are obtained from the broadcast message.
It should be noted that, in each embodiment of the present application, the monitoring parameter in the second period and the duration of the second period, and the start time and/or the end time of the second 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 stopping monitoring the first scheduling information when the condition for stopping monitoring is met by the terminal.
Wherein, the condition for stopping the monitoring may include the following condition (one) or condition (two):
and (3) in the condition (I), the first downlink data is successfully received in the second time period.
For example, if the terminal monitors the first scheduling information in the second time period, the terminal receives the first downlink data 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 as to save the energy consumption of the terminal.
Taking fig. 6b as an example, if the terminal is at a certain time point within the time t1 to the time t2, the following are: and at the middle time from the time t1 to the time t2, successfully receiving the first downlink data according to the time-frequency resource position indicated by the monitored first scheduling information, and stopping monitoring the first scheduling information from the time point by the terminal.
Condition (two), the second time period ends.
For example, the terminal may not monitor the first scheduling information for the second period of time, or the terminal may monitor the first scheduling information for the second period of time, but may not receive the first downlink data according to the time-frequency location information indicated by the first scheduling information for the second period of time, and may stop monitoring the first scheduling information at the end of the second period of time.
The condition for stopping the monitoring may also include a condition (one) and a condition (two), and the monitoring is stopped when the condition (one) is satisfied in the second period of time, and the monitoring is stopped after the second period of time has elapsed.
Taking fig. 6b as an example, if the terminal does not monitor the first scheduling information or does not receive the first downlink data in the time t1 to the time t2, the terminal may stop monitoring the first scheduling information from the 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 a first period of time after transmitting the first message including the uplink data, but monitor the scheduling information for scheduling the first downlink data after the first period of time is completed. Thus, by setting the first time period, the sleep time between the terminal sending the first message and monitoring the scheduling information can be increased, and the power consumption of the terminal can be 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 the time t0 after the terminal sends the first message to the network equipment, closing the radio frequency module of the terminal during the operation of the first timer, and not monitoring the first scheduling information until the first timer is ended. And starting a radio frequency module of the first timer at the time t1 when the first timer is finished, and monitoring the first scheduling information. Alternatively, the starting time of the first time period in fig. 6a may be later than the time t0, and may be separated from the time t0 by one or more slots/symbols; alternatively, the starting time of the first time period in fig. 6a may be equal to or later than the time at which the successful transmission of the first message is determined (not shown in fig. 6 a).
As another example, as shown in fig. 6b, a first period of time is set: time t0 to time t1, the second time period: time t1 to time t 2. And starting a first timer corresponding to the first time period at the time t0 after the terminal sends the first message to the network equipment, closing the radio frequency module of the terminal during the operation of the first timer, and not monitoring the first scheduling information until the first timer is ended. And starting a second timer corresponding to the second time period at the time t1 when the first timer is ended, starting a radio frequency module of the second timer during the operation period of the second timer, and monitoring the first scheduling information. Alternatively, the starting time of the first time period in fig. 6b may be later than the time t0 and separated from the time t0 by one or more slots/symbols, or the starting time of the first time period in fig. 6b may be equal to or later than the time when the successful transmission of the first message is determined (not shown in fig. 6 b); the start time of the second time period in fig. 6b may also be later than the time t1, separated from the time t1 by one or more slots/symbols.
As another example, as shown in fig. 6c, a first period of time is set: time t0 to time t1, the second time period: time t2 to time t 3. And starting a first timer corresponding to the first time period at the time t0 after the terminal sends the first message to the network equipment, closing the radio frequency module of the terminal during the operation of the first timer, and not monitoring the first scheduling information until the first timer is ended. And starting a second timer corresponding to the second time period at the time t2 after the first timer is ended, starting a radio frequency module of the second timer during the operation period of the second timer, and monitoring the first scheduling information. Alternatively, the starting time of the first time period in fig. 6c may be later than the time t0 by one or more slots/symbols from the time t0, or the starting time of the first time period in fig. 6c may be equal to or later than the time when the successful transmission of the first message is determined (not shown in fig. 6 c).
As another example, as shown in fig. 6d, three time periods are set: a first period of time: time t1 to time t2, the second time period: time t3 to time t4, third period: time t0 to time t1. 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 operation of the third timer, monitoring information for scheduling retransmission of the first message, if the information for scheduling retransmission of the first message is not monitored, determining that the first message is successfully sent, and starting the first timer corresponding to the first time period at the time t1 after the successful transmission of the first message. And closing the radio frequency module of the first timer during the operation period of the first timer, and not monitoring the first scheduling information until the first timer is over. And starting a second timer corresponding to the second time period at a time t3 after the first timer is ended, starting a radio frequency module of the second timer during the operation 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 slots/symbols, and the starting time of the second time period in fig. 6d may be the time t2 without limitation.
In the following, in combination with the scenario of receiving and transmitting micro-messages by a mobile phone, shown in fig. 7, a terminal is used as the mobile phone, a network device is used as a base station, the mobile phone is in an idle state, the mobile phone transmits uplink data through a two-step random access process, the time for a high layer of the base station to receive the uplink data, generate high layer feedback information corresponding to the uplink data, and code-modulate the high layer feedback information to a bottom layer of the base station to transmit is 200ms, and the transmission delay between the mobile phone and the base station is 50ms, which is an example, and 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.
The base station transmits 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 relevant configuration of the first time period comprises the duration of the first time period, the starting time and/or the ending time of the first time period, and the relevant configuration of the second time period comprises the duration of the second time period, the starting time and/or the ending time of the second time period. The duration of the first period may be set to 100ms and the duration of the second period may be set to 100ms.
The mobile phone monitors the broadcast message, acquires 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 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 scene, when a user sends a WeChat message through a mobile phone, the WeChat message sent by the user has only one number or one word, the data volume is smaller, the terminal equipment can not enter a connection state, and the WeChat message with smaller data volume is sent in a non-connection state through a small packet data sending mode. At this time, the mobile phone generates a data message corresponding to the micro-message, sends 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 operation 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 the WeChat server, and the WeChat server analyzes the WeChat message and sends a high layer feedback message. The high layer of the base station obtains the high layer feedback information from the server, such as 'successful message sending', and sends the high layer feedback information to the bottom layer of the base station, the bottom layer of the base station carries out code modulation processing on the high layer feedback information to obtain downlink data, and carries the downlink data and the response message which is determined by the bottom layer of the base station and is received by the msgA in the msgB, and sends scheduling information for scheduling the msgB and the msgB to the mobile phone.
After the first timer is stopped, the mobile phone starts a second timer, and starts to monitor the scheduling information of the scheduling msgB according to the monitoring parameters in the second time period. If the scheduling information of the scheduling msgB is monitored during the operation period of the second timer, stopping monitoring, receiving the msgB at a time-frequency resource position indicated by the scheduling information of the scheduling msgB, acquiring high-level feedback information from the received msgB, and receiving the high-level feedback information: the "successful message transmission" is presented to the user. Of course, the "successful message transmission" presented in fig. 7 is only an example, and the message may not be displayed or the successful transmission may be indicated by other display means.
Compared with the existing monitoring method for monitoring the scheduling information for scheduling the msgB when the mobile phone transmits the msgA, the existing monitoring method has the advantages that the mobile phone needs to occupy about 200ms to monitor the scheduling information for scheduling the msgB, the time for monitoring the scheduling information in the method shown in fig. 7 is about 100ms, the monitoring time is shortened, the time for the mobile phone to sleep is prolonged, and the power consumption of the mobile phone is reduced.
The method shown in fig. 5 and fig. 7 is for example to transmit, to a terminal, a response message determined by the bottom layer of the network device and received the first message and high-layer feedback information corresponding to uplink data determined by the high layer of the network device, and a method for monitoring scheduling information by the terminal in an idle state or a non-active state is described. 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 the network device receives the first message including the uplink data, the network device happens to have the downlink service to need the terminal to switch to the connection state, at this time, the network device may send the response message determined by the bottom layer of the network device and received the first message to the terminal as soon as possible, and send the high-layer feedback information corresponding to the uplink data determined by the high layer of the network device as normal downlink data to the terminal when the terminal switches to the connection state. And in the second case, after the network equipment receives the first message comprising the uplink data, the response message which is determined by the bottom layer of the network equipment and is received by the first message and the high-layer feedback information which corresponds to the uplink data and is 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 transmitting a response message which is determined by the bottom layer of the network equipment and is used for receiving the first message to the terminal as soon as possible, then dispatching the high-level feedback information which corresponds to the uplink data and is determined by the high-level of the network equipment to the terminal, and simultaneously, indicating the terminal to monitor the dispatching information for dispatching the high-level feedback information in a certain time period after the dispatching information after the dispatching response message is monitored.
For the terminal, it is unknown which case the network device uses to send downlink data, in order to ensure that the terminal can receive downlink data sent by the network device when in an idle state or inactive state, and reduce power consumption of the terminal for monitoring scheduling information for scheduling the downlink data. Specifically, the method may be as shown in fig. 8.
Fig. 8 is a schematic diagram of a monitoring method according to an embodiment of the present application, where the method is performed 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 of step 801 may be described with reference to step 501, for example: the first message is sent to the network device via msg3 or msgB or a configuration scheduling message, which will not be described in detail.
The network device receives the first message, performs step 802a or step 802b or step 803c:
step 802a: the network device sends first scheduling information and first downlink data to the terminal.
The first scheduling information may be used to schedule the first downlink data. The network device sending the first scheduling information to the terminal may include: and the network equipment sends the first scheduling information to the terminal through the PDCCH, and sends the first downlink data to the terminal at the time-frequency resource position indicated by the first scheduling information.
The first downlink data in step 802a is different from the first downlink data in step 502, where the first downlink data in step 802a may include a response message determined by the 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 a connection state. Corresponding to the first message sent by the terminal, the network device may send the first downlink data to the terminal through msg4 in the four-step random access procedure, or send the first downlink data to the terminal through msgA in the two-step random access procedure, or send the first downlink data to the terminal through the configuration scheduling response in the modes (2.1) to (2.3) described above.
If the network device sends the first scheduling information and the first downlink data to the terminal, the network device determines that the response message determined by the network device and corresponding to the uplink data and determined by the bottom layer are not included together, and is likely to be sent to the terminal, when the terminal is switched to a connection state, the high-layer feedback information corresponding to the uplink data is likely to be used as the response message to be sent to the terminal, and after the terminal monitors the first scheduling information, the terminal does not need to monitor the scheduling information in an idle state or an inactive state. Otherwise, if the network device wishes to send 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 execute step 802b.
Step 802b: the network device sends 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 first scheduling information may be used to schedule the first downlink data. The network device sending the first scheduling information to the terminal may include: and the network equipment sends the first scheduling information to the terminal through the PDCCH, and sends the first downlink data to the terminal at the time-frequency resource position indicated by the first scheduling information.
The second scheduling information may be used to schedule the second downlink data. The network device sending the second scheduling information to the terminal and the second downlink data 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 and indication information determined by the bottom layer of the network device. The response message may be used to instruct the terminal network device to receive the first message, and may further be used to instruct the terminal to switch 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 the first scheduling information is monitored, 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 starting time and/or the ending time of the fifth time period.
Corresponding to the first message sent by the terminal, the network device may send the first downlink data to the terminal through msg4 in the four-step random access procedure, or send the first downlink data to the terminal through msgA in the two-step random access procedure, or send the first downlink data to the terminal through the configuration scheduling response in the modes (2.1) to (2.3) described above.
In step 802b, the network device decouples the response message determined by the bottom layer of the network device from the higher layer feedback information determined by the higher layer of the network device. The network device transmits the first scheduling information earlier than the network device transmits the second scheduling information. For example, the time of the first scheduling information sent by the network device may be determined according to the time of the bottom layer of the network device determining the response message, and the time of the second scheduling information sent by the network device may be determined according to the time of the higher layer determining the higher layer feedback information of the network device to the bottom layer of the network device receiving and processing the higher layer feedback information.
The related descriptions of the upper layer of the network device and the lower layer of the network device may be described with reference to fig. 2, and the process of generating the upper layer feedback information by the upper layer of the network device and the process of performing code modulation on the upper layer feedback information by the lower layer of the network device may be described with reference to the prior art, which are not repeated.
Step 802c: the network device 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 is different from the second downlink data in step 802b, where the second downlink data in step 802c may include not only high-layer feedback information corresponding to the uplink data, but also a response message determined by the bottom layer of the network device. Corresponding to the first message sent by the terminal, the network device may send the second downlink data to the terminal through msg4 in the four-step random access procedure, or send the second downlink data to the terminal through msgA in the two-step random access procedure, or send the second downlink data to the terminal through the configuration scheduling response in the manner described in the modes (2.1) to (2.3).
That is, in step 802c, the network device includes the response message determined by the bottom layer of the network device and the higher layer feedback information determined by the higher layer of the network device together in the second downlink data and transmits the second downlink data to the terminal. At this time, the time when the network device transmits the second scheduling information may depend on the time when the higher layer of the network device determines that the higher layer feedback information is received and processed by the lower layer of the network device.
Step 803: and the terminal monitors the first scheduling information in a fourth time period after the first message is sent.
The fourth time period may be used to limit a duration of monitoring the first scheduling information by the terminal. 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, for example: the network device broadcasts the duration of the fourth time period, the starting time and/or the ending time of the fourth time period in the broadcast message, the terminal receives the broadcast message, and acquires the duration of the fourth time period, 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 starting time and/or the ending time of the fourth time period may be predetermined by the protocol, without limitation.
For example, the terminal may configure a fourth timer according to a duration of the fourth time period, a start time and/or an end time of the fourth time period, where the duration of the fourth timer is equal to the duration of the fourth time period, a start time of the fourth timer corresponds to the start time of the fourth time period, after the terminal sends the first message, the fourth timer is started, and the first scheduling information is monitored during a validity period/an operation period of the fourth timer.
Wherein the start time of the fourth time period is related to the end time of the sending of the first message. In one possible design, the start time of the fourth time period may be equal to or later than the end time of the first message being sent for the first time, such as: the starting time of the fourth time period may be the ending time of the first message being transmitted for the first time, or the starting time of the fourth time period may be a time domain position separated from the ending time of the first message being transmitted for the first time by several slots/symbols after the ending time of the first message being transmitted for the first time. As shown in fig. 9a, the start time of the fourth period is the end time t0 of the transmission of the first message.
In yet another possible design, to ensure that the first message is successfully sent, the start time of the fourth time period may be set equal to or later than the time at which it is determined that the first message was successfully sent. For example, the starting time of the fourth period may be a time at which the first message is determined to be successfully transmitted, or the starting time of the fourth period may be a time domain position separated from the time at which the first message is determined to be successfully transmitted by a few slots/symbols after the time at which the first message is determined to be successfully transmitted. As shown in fig. 9b, the start time of the fourth period is time t1 when it is determined that the first message was successfully transmitted.
Wherein the terminal may determine whether the first message was transmitted successfully by monitoring information scheduling retransmission of the first message during the fourth period of time. The detailed description of the fourth time period and the specific implementation of determining whether the first message is sent successfully may be described in step 403, which is not repeated.
For example, the terminal monitoring the first scheduling information in the fourth period may include: 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 monitored parameters in the fourth time period may include: configuration of a search space, CORESET configuration, and RNTI corresponding to the first scheduling information. The configuration of the search space may include one or more of information of a monitoring period of the search space, a downlink control information DCI format 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 in the fourth time period may refer to the existing description, which is not repeated.
The monitoring parameters in the fourth period may also be determined by the terminal according to the network device configuration, for example: the network device broadcasts the monitoring parameters in the fourth time period in the broadcast message, the terminal receives the broadcast message broadcast by the network device, and the monitoring parameters in the fourth time period are obtained from the broadcast message.
It should be noted that, in each embodiment of the present application, the monitoring parameter in the fourth time period and the duration 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, which is not limited.
Step 804: the terminal monitors the second scheduling information in a fifth time period after the fourth time period.
The terminal determines that the first scheduling information is not monitored in the fourth time period, and monitors the second scheduling information in a fifth time period after the fourth time period; or when the terminal determines that the first downlink data comprises the indication information, the indication information is used for indicating that the second scheduling information is monitored in the fifth time period, and the second scheduling information is monitored in the fifth time period according to the indication information. If the terminal determines that the first scheduling information is monitored in the fourth time period, the terminal receives that the indication information is not included in the first downlink data according to the time-frequency resource position indicated by the first scheduling information, and then the terminal does not monitor the second scheduling information in a fifth time period after the fourth time period.
Wherein the fifth time period may be used to limit the duration of the monitoring of the second scheduling information by the terminal. The fifth time period corresponds to the time when the higher layer of the network device sends the higher layer feedback information to the terminal. In one possible design, the duration of the fifth time period, 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 acquires the duration of the fifth time period, the starting time and/or the ending time of the fifth time period from the broadcast message. In yet another possible design, the duration of the fifth time period, the start time and/or the end time of the fifth time period may be included in the above indication information and configured to the terminal. In a further possible embodiment, the duration of the fifth time period, the starting time and/or the ending time of the fifth time period may also be predefined by the protocol without limitation.
For example, the terminal may configure a fifth timer according to a duration of the fifth time period, a start time and/or an end time of the fifth time period, where the duration of the fifth timer is equal to the duration of the fifth time period, a start time of the fifth timer corresponds to the start time of the fifth time period, the fifth timer is started after the terminal sends the first message, and the second scheduling information is monitored during an validity period/operation period of the fifth timer.
Wherein the start time of the fifth period may be equal to or later than the end time of the fourth period. Such as: the starting time of the fifth time period may be the ending time of the fourth time period, or the starting time of the fifth time period may be a time domain position separated from the ending time of the fourth time period by several slots/symbols after the ending time of the fourth time period.
For example, the terminal monitoring the second scheduling information in the fifth period of time 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 monitored parameters in the fifth time period may include: configuration of search space, CORESET configuration, and RNTI corresponding to the second scheduling information. The configuration of the search space may include one or more of information of a monitoring period of the search space, a downlink control information DCI format to be monitored, a number of candidates to be monitored, and an aggregation level to be monitored. The relevant 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 in the fifth time period may refer to the existing description, which is not repeated.
In order to reduce the power consumption of the terminal, the monitoring period of the search space corresponding to the fifth period may be set to be greater than or equal to the monitoring period of the search space corresponding to the fourth period.
The monitoring parameters in the fifth time period may also be determined by the terminal according to the network device configuration, for example: the network equipment broadcasts the monitoring parameters in the fifth time period in a broadcast message, the terminal receives the broadcast message broadcast by the network equipment, and the monitoring parameters in the fifth time period are obtained from the broadcast message; or the network device includes the monitoring parameter in the fifth time period in the indication information and configures the terminal.
In the embodiments 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 and 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, without limitation.
Further, to avoid the terminal monitoring the second scheduling information indefinitely, the method shown in fig. 8 may further include: and stopping monitoring the second scheduling information when the condition for stopping monitoring is met.
Wherein, the condition for stopping monitoring may be described with reference to the above step 504, and may include that the second downlink data is successfully received in the fifth period of time; alternatively, the fifth period of time ends.
For example, if the terminal monitors the second scheduling information in the fifth time period, the terminal receives the second downlink data according to the time-frequency resource position indicated by the second scheduling information, and the second downlink data is successfully received through verification, monitoring of the second scheduling information is stopped, so as to save the energy consumption of the terminal. Or if the terminal does not monitor the second scheduling information in the fifth time period, the terminal stops monitoring the second scheduling information at the end of the fifth time period. 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, the terminal can stop monitoring the second scheduling information when the fifth time period is over.
After the method shown in fig. 8 is applied to the terminal, the terminal can monitor the first scheduling information in the fourth time period, monitor the second scheduling information in the fifth time period, i.e. set a specific time period, monitor the scheduling information in the specific time period, so as to avoid the problem of larger power consumption caused by infinitely monitoring the scheduling information. 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 two time periods, so as to ensure the accuracy of receiving the downlink data under the condition that the network device flexibly transmits the downlink data.
For example, as shown in fig. 9a, a fourth period of time is set: time t0 to time t1, 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 equipment, starting a radio frequency module of the terminal during the operation of the fourth timer, and monitoring the first scheduling information until the fourth timer is ended. If the first scheduling information is monitored during the operation period of the fourth timer and the first downlink data is received according to the first scheduling information, the second scheduling information is not monitored in the fifth time period.
As another example, as shown in fig. 9b, a fourth period of time is set: time t0 to time t1, 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 equipment, starting a radio frequency module of the terminal during the operation of the fourth timer, and monitoring the first scheduling information until the fourth timer is ended. If the first scheduling information is not monitored during the operation period of the fourth timer, starting a fifth timer corresponding to the fifth time period at the time t2 after the end of the fourth timer, starting a radio frequency module of the fifth timer during the operation period of the fifth timer, and monitoring the second scheduling information.
As another example, as shown in fig. 9c, a fourth period of time is set: time t0 to time t1, 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 equipment, starting a radio frequency module of the terminal during the operation of the fourth timer, and monitoring the first scheduling information until the fourth timer is ended. If the first scheduling information is monitored during the operation period of the fourth timer, the first downlink data is received according to the first scheduling information, and the first downlink data comprises indication information for indicating the terminal to monitor the second scheduling information in the fifth time period, the terminal starts the fifth timer corresponding to the fifth time period at the time t2 according to the indication information, starts the radio frequency module of the terminal during the operation period of the fifth timer, and monitors the second scheduling information.
In the following, in combination with the scenario that the user receives and transmits the micro-message through the mobile phone shown in fig. 10, the terminal is used as the mobile phone, the network device is used as the base station, the mobile phone is in an idle state, the mobile phone transmits uplink data through a two-step random access process, after receiving the uplink data, a high layer of the base station feeds back a response message determined by a bottom layer to the terminal as soon as possible, then generates high layer feedback information corresponding to the uplink data, and transmits the high layer feedback information to the terminal for example, and the monitoring method shown in fig. 8 is described.
As shown in fig. 10, the mobile phone is in an idle state and can receive a broadcast message sent by the base station.
The base station transmits a broadcast message, wherein the broadcast message comprises the related configuration of the fourth time period, the related 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 may be set to 50ms and the duration of the fifth period may be set to 100ms.
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 parameters 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 scene, when a user sends a WeChat message through a mobile phone, the WeChat message sent by the user has only one number or one word, the data volume is smaller, the terminal equipment can not enter a connection state, and the WeChat message with smaller data volume is sent in a non-connection state through a small packet data sending mode. At this time, the mobile phone generates a data message corresponding to the micro-message, sends msgA to the base station, carries the data message in the msgA, starts a fourth timer after sending the msgA, and monitors scheduling information for scheduling the msgB during the operation of the fourth timer.
The bottom layer of the base station receives the msgA, and firstly feeds back a response message and indication information to the terminal, for example: and carrying the response message and the indication information in the msgB, and sending the scheduling information for scheduling the msgB and the msgB to the mobile phone. Meanwhile, the msgA is decoded, demodulated and processed to obtain a data message, the data message is sent to a 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 analyzes the WeChat message and sends high-layer feedback information. The high layer of the base station obtains the high layer feedback information from the server, such as 'successful message sending', and sends the high layer feedback information to the bottom layer of the base station, the bottom layer of the base station carries out code modulation processing on the high layer feedback information to obtain downlink data, and sends scheduling information for scheduling the downlink data and the downlink data to the mobile phone.
And the mobile phone monitors the scheduling information for scheduling the msgB in the running period of the fourth timer, receives the indication information at the time-frequency resource position indicated by the scheduling information for scheduling the msgB, starts the fifth timer according to the indication information, and starts to monitor the scheduling information for scheduling the downlink data according to the monitoring parameters in the fifth time period. If the scheduling information of the downlink data is monitored in the operation period of the fifth timer, stopping monitoring, receiving the downlink data at the time-frequency resource position indicated by the scheduling information of the downlink data, acquiring high-level feedback information from the received downlink data, and receiving the high-level feedback information: the "successful message transmission" is presented to the user. Of course, the "successful message transmission" presented in fig. 10 is merely an example, and the message may not be displayed or the successful transmission may be indicated by other display means.
Compared with the existing monitoring method for monitoring the scheduling information for scheduling the msgB when the mobile phone transmits the msgA, the mobile phone in the existing monitoring method needs to occupy about 200ms to monitor the scheduling information for scheduling the scheduling information including the response information and the high-level feedback information, and the monitoring method of the method shown in fig. 10 comprises two monitoring, wherein the total time for monitoring the scheduling information twice is about 150ms, the monitoring time is shortened, and the power consumption of the mobile phone is reduced.
Further, in the monitoring method shown in fig. 5 to fig. 10, in order to reduce the power consumption of the terminal better, the search space of the scheduling information for scheduling the packet data may be set to be different from the first search space, for example: the number of the search spaces for scheduling the scheduling information of the small packet data is set to be smaller, the blind detection times are reduced, and the power consumption of the terminal is reduced. Alternatively, the monitoring period of the search space for scheduling information for scheduling the small packet data is set to be different from the first search space, such as: the monitoring period of the search space for scheduling the scheduling information of the small packet data is set to be longer than 5 time slots (slots)/10 slots, so that the frequency of monitoring the scheduling information by the terminal is reduced, and the power consumption of the terminal is further reduced.
Wherein the first search space may be a search space for monitoring scheduling information for scheduling non-small 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 for scheduling the packet data may be referred to as random access search space packet data (ra-search space small data) or packet data random access search space, may also be referred to as dedicated search space, etc., 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 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 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 within a fifth period of time, and the monitoring period of the search space of the second scheduling information may refer to a monitoring period of the search space within the fifth period of time.
For example, taking a four-step random access procedure, a search space for scheduling information of packet data is called 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 transmits 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 the dedicated preamble sequence resource and start monitoring scheduling information for scheduling msg2/msg3/msg4 in the dedicated search space after transmitting msg 1.
For another example, taking a four-step random access procedure, a search space for scheduling information of packet data is called a dedicated search space, as shown in fig. 11c, a terminal may monitor the scheduling information for scheduling msg2 in a ra-search space by using a monitoring period of the ra-search space, monitor the scheduling information for scheduling msg3 in the ra-search space by using a monitoring period of the ra-search space, and switch to the dedicated search space after the terminal has sent msg3 carrying the packet data, and monitor the scheduling information for scheduling msg4 by using a monitoring period of the dedicated search space. Alternatively, as shown in fig. 11d, the terminal may directly transmit msg1 using the dedicated preamble sequence resource, and start monitoring scheduling information for scheduling msg2/msg3/msg4 in the dedicated search space by applying a monitoring period of the dedicated search space after transmitting msg 1.
