Description

A monitoring method and device

Technical field

The embodiments of the present application relate to the field of communication technology, and in particular, to a monitoring method and device.

Background technique

Currently, when the terminal is in the idle state or the inactive state, if the terminal needs to send uplink service data to the network device, the terminal needs to initiate a random access process and switch from the idle/inactive state to the connected state. After the status is reached, the uplink service data is sent to the network device. Among them, if the uplink service data is small packet data and the amount of data is small, at this time, sending less data also requires initiating a complete random access process, which will increase the signaling overhead and power consumption of the terminal.

In order to reduce the signaling overhead and power consumption of the terminal, the terminal can send small packet data to the network device during the random access process. After receiving the small packet data, the network device can send a downlink data to the terminal, including a bottom-layer confirmation message to confirm the completion of sending the small packet data and high-level feedback information including the network device.

However, the feedback speed of the low-level confirmation message is generally relatively fast, for example, it can be completed within 5ms, while the generation of high-level feedback information is generally relatively slow, and may take more than 200ms. 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 before sending the corresponding physical downlink control channel (PDCCH) and corresponding messages for scheduling, with a long interval. Therefore, for the terminal, the continuous monitoring time of monitoring the corresponding PDCCH in the preconfigured search space is longer, which increases the power consumption of the terminal.

Detailed ways

Before introducing the embodiments of this application, some terms involved in the embodiments of this application are explained:

The connected state can be called a radio resource control connected (RRC-connected) state. In the connected state, the terminal is connected to a network device (such as an access network device), and data is transmitted between the two. For example, the terminal can receive downlink data from the network device or send uplink data to the network device.

The idle state can be called radio resource control idle (RRC-idle) state. In the idle state, the terminal and network equipment (such as access network equipment) are not connected. The network equipment does not know whether the terminal is within the coverage of the network equipment. The terminal can receive paging messages and synchronization from the network equipment. One or more of signals, broadcast messages, or system information, but it cannot conduct voice calls, large-volume Internet access, and other data transmission with network equipment.

The inactive state may be called radio resource control inactive (RRC-inactive) state. In the non-connected state, the terminal and network equipment (such as access network equipment) are not connected, but the context of the terminal can be saved in the network equipment, and the terminal can receive paging messages, synchronization signals, broadcast messages, or system information from the network equipment. One or more of them, but cannot conduct voice calls, large-volume Internet access and other data transmission with network equipment.

Among them, the idle state or inactive state can be called non-connected state or sleep state.

In order to reduce the power consumption of sending small packet data when the terminal is in a non-connected state, the terminal sends small packet data to the network device through a random access process or a configuration grant (CG) process. The random access process may include a four-step random access process and a two-step random access process. Small data can refer to data whose number of bits is less than or equal to a preset value. The preset value is set as needed. For example, the packet data may be several bits of data, tens of bits, or hundreds of bits of data. For example, the preset value may be 100 bits, 10 bits, etc.

Referring to Figure 1a, it is a four-step random access process, which may include: step (1), the terminal sends a first message (msg1) to the network device to notify the network device of a random access request. The first message may also be called a random access preamble (random access preamble). Step (2): After receiving msg1, the network device sends a random access response to the terminal. The random access response may also be called the second message (msg2). Step (3): After receiving the random access response, the terminal sends a third message (msg3) to the network device, where msg3 may include small packet data and other information. Step (4): The network device sends a fourth message (msg4) to the terminal. The fourth message may include a response message determined by the lower layer of the network device and high-level feedback information corresponding to the small packet data determined by the upper layer of the network device. The network equipment may include access network equipment, core network equipment, and service provider equipment (such as servers). It should be noted that in the first step when the terminal sends a 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 equipment to be scheduled to the terminal through the physical downlink control channel (PDCCH). For example, before sending msg2/msg3/msg4, the network equipment will send msg2/msg3/msg4 for scheduling. PDCCH, send msg2/msg3/msg4 at the time-frequency resource position indicated by the PDCCH.

Referring to Figure 1b, it is a two-step random access process, which may include: step (1), the terminal sends msgA to the network device. msgA may include preamble, small packet data and other information. Step (2): The network device receives msgA and replies to the terminal with msgB. msgB may include a response message determined by the lower layer of the network device and high-level feedback information corresponding to the small packet data determined by the upper layer of the network device. The network equipment may include access network equipment, core network equipment, and service provider equipment (such as servers). 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 subsequent msgB requires the network device to schedule it to the terminal through the PDCCH. For example, before sending the msgB, the network device will send the PDCCH used to schedule the msgB, and send the msgB at the time-frequency resource position indicated by the PDCCH.

Referring to Figure 1c, the CG process may include: Step (1): The network device sends uplink resource configuration information to the terminal, and configures uplink resources for the terminal to send uplink data. Step (2): The terminal sends a configuration scheduling message including small packet data to the network device on the uplink resource configured by the network device. Step (3): The network device receives the small packet data and sends a configuration scheduling response to the terminal. The configuration scheduling response may include a response message determined by the bottom layer of the network device and high-level feedback information corresponding to the small packet data determined by the upper layer of the network device. The network equipment may include access network equipment, core network equipment, and service provider equipment (such as servers).

When the terminal communicates with the network device, a protocol layer as shown in Figure 2 can be established between the terminal and the network device. As shown in Figure 2, the terminal can include transmission control protocol (TCP)/Internet Protocol ( internet protocol (IP) layer and physical layer (physical, PHY). Network equipment can include TCP/IP layer and physical layer. The TCP/IP layer of the terminal can be called the high layer of the terminal, the physical layer of the terminal can be called the bottom layer of the terminal, the TCP/IP layer of the network device can be called the high layer of the network device, and the physical layer of the network device can be called the network device. Ground floor.

When the terminal sends uplink data to the network device, the terminal's TCP/IP generates uplink data, such as small packet data. The uplink data is packaged and transmitted to the terminal's physical layer. The terminal's physical layer encodes and modulates the uplink data and transmits it through the air interface. The physical layer of network equipment. After the physical layer of the network device receives the uplink data, the physical layer of the network device will generally send a "physical layer response message" to the physical layer of the terminal so that the terminal knows that the uplink data packet has been transmitted correctly at the physical layer. At the same time, 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, it generates a high-level feedback information of the TCP/IP layer and feeds it back to the terminal through the physical layer of the network device (as shown by the dotted line in Figure 2). Because the TCP/IP layer of the network device takes a long time to generate and send high-level feedback information, usually 200ms, so after the terminal sends the small packet data, it often receives a high-level feedback information after a relatively long period of time. At this time, if the terminal has been monitoring the scheduling information used for scheduling high-level feedback information for a long period of time, the power consumption of the terminal will be increased.

In order to solve the major problem of power consumption of the terminal, embodiments of the present application provide a monitoring method for reducing the power consumption of the terminal monitoring scheduling information. The monitoring method for reducing power consumption of terminal monitoring scheduling information provided by embodiments of the present application will be described below with reference to the accompanying drawings.

The monitoring method provided by the embodiments of the present application can be used in fourth generation (4th generation, 4G) systems, long term evolution (long term evolution, LTE) systems, fifth generation (5th generation, 5G) systems, and new radio interfaces (newradio, NR).

As shown in Figure 3, the communication system may include a network device and multiple terminals, such as Terminal 1 and Terminal 2. In the system shown in Figure 3, the terminal can be either in an idle state or in an inactive state. It should be noted that Figure 3 is an exemplary framework diagram.

The following describes the monitoring method provided by the embodiments of the present application, taking the device for realizing the functions of the terminal being a terminal as an example.

In the system shown in Figure 3, in order to reduce the power consumption of the terminal, after the terminal in the non-connected state sends uplink data to the network device through the msg3/msgA/configuration scheduling message, it can not monitor for a period of time for scheduling msg4 or msgB or configure the scheduling information of the scheduling response, and then start monitoring the scheduling information. Or, set two time periods. After the terminal sends uplink data to the network device through the msg3/msgA/configuration scheduling message, in the first time period, it monitors the scheduling information used to schedule msg4 or msgB or configure the scheduling response. In the first time period, If the scheduling information is monitored in the first time period, it will not be monitored in the second time period; or, if an indication information is detected in the first time period, the indication information indicates whether the terminal should monitor in the second time period. Monitor during the second time period based on this instruction information. In this way, the power consumption caused by the terminal continuously monitoring the PDCCH after sending the msg3/msgA/configuration scheduling message can be reduced. Specifically, the monitoring method may be described in the corresponding embodiments of FIGS. 5 to 10 .

Figure 5 shows a monitoring method provided by an embodiment of the present application. By setting a time period in which scheduling information is not monitored, the terminal sleep duration is increased and the power consumption of the terminal is reduced. As shown in Figure 5, the method may include:

Step 501: The terminal sends the 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 can be any network device in the communication system shown in Figure 3 that can provide network services for the terminal.

The first message may include uplink data. The terminal can obtain the uplink data in the following manner: the upper layer of the terminal generates data and sends the generated data to the lower layer of the terminal, and the lower layer of the terminal encodes and modulates the received data to obtain the uplink data. The relevant description of the upper layer of the terminal and the lower layer of the terminal can be referred to that described in Figure 2. The process of the upper layer of the terminal generating data and the process of the lower layer of the terminal encoding and modulating data can refer to the existing technology and will not be described again.

It should be noted that in the embodiments of this application, uplink data and downlink data are relative concepts. Uplink data may refer to data sent from the terminal to the 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 process or a two-step random access process or a configuration scheduling process. The sending method is described with reference to methods (1.1) to (1.3):

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

For example, the terminal may include the uplink data in the first message, and include the first message in msg3 and send it to the network device; or, include the uplink data in the first message, and send the first message as msg3 to the network device, At this time, the first message can be called msg3.

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

For example, the terminal may include the uplink data in the first message and send the first message to the network device as msgA; or the terminal may include the uplink data in the first message and send the first message to the network device as msgA. , at this time, the first message can be called msgA.

In method (1.3), the terminal sends the 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 resources preconfigured by the network device to the terminal; or, the terminal may The uplink data is included in the first message, the first message is used as a configuration scheduling message, and the first message is sent to the network device on the uplink transmission resources preconfigured by the network device for the terminal. At this time, the first message may be called a configuration scheduling message. .

Among them, the embodiment of the present application does not limit the naming of the configuration and scheduling messages. The configuration and scheduling messages can also be named as pre-configuration messages or pre-setting messages or messages with other names, without limitation.

Since the amount of data transmitted by the above three sending methods is limited, for example, data with a small amount of data is transmitted, in order to ensure the reliability of data transmission. Exemplarily, before executing step 501, the terminal determines whether the amount of uplink data is less than the preset value. When it is determined that the amount of uplink data is less than the preset value, it sends a first message to the network device, such as: the terminal turns on its own The radio frequency module uses any one of the above methods (1.1) to (1.3) to send the first message to the network device. The radio frequency module may be the communication interface described in Figure 4.

Among them, the preset value can be set as needed and is not limited. If the data amount of the uplink data is less than the preset value, it means that the uplink data is small packet data. On the contrary, if the data amount of the uplink data is greater than or equal to the preset value, it means that the uplink data is non-small packet data. Specifically, the preset value can be stipulated in the standard first, or can be broadcast and configured through the system message of the network device.

Step 502: The network device receives the first message and sends the first scheduling information and the 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 and the first downlink data to the terminal may include: the network device sending the first scheduling information to the terminal through the PDCCH, and sending the first downlink to the terminal at the time-frequency resource position indicated by the first scheduling information. row data.

The first downlink data may be high-level feedback information corresponding to the uplink data, and the first downlink data may be small packet data, that is, the data amount of the first downlink data is less than a preset value. For example, the network device can obtain the first downlink data in the following manner: after receiving the first message, the lower layer of the network device decodes and demodulates the uplink data included in the first message and sends it to the higher layer of the network device; After receiving the data sent by the bottom layer of the network device, the high layer of the network device generates high layer feedback information corresponding to the data, and sends the generated high layer feedback information to the bottom layer of the network device. The bottom layer of the network device encodes the high layer feedback information. Modulate to obtain the first downlink data.

Among them, the relevant description of the upper layer of the network device and the lower layer of the network device can be referred to as shown in Figure 2. The process of the upper layer of the network device generating high-level feedback information and the process of the lower layer of the network device encoding and modulating the high-level feedback information can be referred to the existing Technology will not be described in detail.

For example, corresponding to the terminal sending the first message, the network device may send the first downlink data to the terminal in any of the following methods (2.1) to (2.3):

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

Method (2.2): The network device sends the first downlink data to the terminal through msgB in the two-step random access process.

In method (2.3), the network device sends the first downlink data to the terminal by configuring a scheduling response.

In method (2.3), in addition to including the first downlink data, the configuration scheduling response may also include the underlying confirmation message and other information included in the existing configuration scheduling response to indicate that the network device has received the first message. limit.

Among them, the embodiment of the present application does not limit the naming of the configuration and scheduling response. The configuration and scheduling response can also be named as preconfiguration information or preset information or information with other names, without limitation.

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

Step 503: The terminal does not monitor the first scheduling information within the first period of time after sending the first message.

The first time period may be used to limit the time period during which the terminal does not monitor scheduling information. The duration of the first time period, the starting moment and/or the ending moment 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 moment and/or the ending moment of the first time period The time is determined in advance by the agreement and is not restricted.

Taking the length of the first time period, the starting time and/or the ending time of the first time period as an example, the network device can pre-configure it to the terminal. The terminal can receive a broadcast message from the network device, and the broadcast message includes the first time. The terminal obtains the duration of the first time period, the start time and/or the end time of the first time period from the broadcast message.

Among them, the duration of the first time period can be set as needed. For example, the first time period can be determined based on the time when the upper layer of the network device generates the high-level feedback information and the time when the lower layer of the network device encodes and modulates the high-level feedback information. For example, the length of the first time period can be set to be less than or equal to the network device. The sum of the time for the upper layer of the device to generate high-level feedback information and the time for the lower layer of the network device to encode and modulate the high-level feedback information.

For example, the terminal may configure a first timer (timing) according to the length of the first time period, the starting time and/or the ending time of the first time period, and the length of the first timer is equal to the length of the first time period. , the starting time of the first timer corresponds to the starting moment of the first time period. After the terminal sends the first message, the first timer is started, and the first scheduling information is not monitored during the validity period/running period of the first timer. In various embodiments of the present application, the terminal not monitoring the first scheduling information may mean that the terminal turns off its own radio frequency module and stops the function of sending and receiving data/information.

The starting time of the first time period is related to the ending time of sending the first message. In one possible design, the starting time of the first time period can be set to be equal to or later than the end time of sending the first message for the first time. For example, the starting time of the first time period can be the end time of sending the first message for the first time. time, or the starting time of the first time period may be a time domain position after the end time of first sending the first message and several slots/symbols away from the end time of first sending the first message. As shown in Figures 6a and 6b, the starting time of the first time period is the end time t0 of sending the first message.

In another possible design, in order to ensure that the first message is successfully sent, the starting time of the first time period may be set to be equal to or later than the time when the first message is determined to be successfully sent. For example, the starting moment of the first time period may be the moment when it is determined that the first message is successfully sent, or the starting moment of the first time period is after the moment when it is determined that the first message is successfully sent, and after the moment when it is determined that the first message is successfully sent. The time domain position of several slots/symbols apart. For example, as shown in Figure 6d, the starting time of the first time period is the time t1 when it is determined that the first message is successfully sent.

In the embodiment of this application, the terminal can monitor the information scheduling the retransmission of the first message within the third time period after the first message is sent for the first time. If the terminal does not receive the information scheduling the retransmission of the first message within the third time period, Then it is determined that the first message is successfully sent. On the contrary, if the information for scheduling the retransmission of the first message is monitored, the first message is resent to the network device according to the information of the first message retransmission, and after resending the first message Start the first time period. The first message retransmission information 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.

Among them, the duration of the third time period, the starting time and/or the ending time of the third time period can be configured by the network device to the terminal, for example: the network device configures it to the terminal through a broadcast message, etc.; or, the third time period The duration, the starting time and/or the ending time of the third time period may be predetermined by the agreement.

For example, the terminal may configure a third timer according to the length of the third time period, the starting time and/or the ending time of the third time period, and the length of the third timer is equal to the length of the third time period. The start time of the timer corresponds to the starting moment of the third time period. After the terminal sends the first message, it starts the third timer and monitors the information of scheduling the retransmission of the first message during the validity period/running period of the third timer.

Among them, the starting time of the third time period can be set to be equal to or later than the end time of sending the first message for the first time. For example, the starting time of the third time period is the end time of the first message, or the third time period The starting time is after the end time of sending the first message for the first time. For example, as shown in Figure 6d, the starting time of the third time period is the end time t0 when the first message is first 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 can also be named a time window (window) or other names. For example, the first time period can be named the first time window, the second time period can be named the second time window, the third time period can be named the third time window, and the fourth time period can be named the fourth time window. The fifth time period can be named the fifth time window, etc.

In addition, each timer described in the embodiment of the present application can be replaced by a counter (counter), and the product of the number of counts of the counter and the duration of each count is equal to the duration of the timer. For example, the first timer can be replaced with a first counter, the second timer can be replaced with a second counter, the third timer can be replaced with a third counter, the fourth timer can be replaced with a fourth counter, and the fifth timer can be replaced with a first counter. counter can be replaced by a fifth counter, etc.

Step 504: After the first time period passes, the terminal monitors the first scheduling information.

The first scheduling information may be used to schedule the first downlink data. For relevant descriptions of the first scheduling information and the first downlink data, reference may be made to step 502, which will not be described again.

In one possible design, after the terminal passes through the first time period, for example, it turns on its own radio frequency module at the end of the first time period and monitors the first scheduling information, or at the i-th time after the end of the first time period. Turn on its own radio frequency module for each time slot/symbol and monitor the first scheduling information. i is an integer greater than or equal to 1. For example, as shown in Figure 6a, the terminal starts monitoring the first scheduling information at the end of the first time period. At this 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, and the terminal turns on its own radio frequency module during the second time period to monitor the first scheduling information, that is, a time period is divided for monitoring the first scheduling information. , monitoring is performed within this time period to save the power consumption of the terminal. For example, as shown in any of Figures 6b to 6d, the terminal sets a second time period after the end of the first time period, and monitors the first scheduling information during the second time period.

The second time period may be used to limit the duration for which the terminal monitors the first scheduling information. The length of the second time period, the starting time and/or the ending time of the second time period may be determined by the terminal according to the configuration of the network device. For example, the network device combines the length of the second time period, the starting time and/or the ending time of the second time period. /or the end time includes being broadcast in a broadcast message. The terminal receives the broadcast message and obtains the duration of the second time period, the start time and/or the end 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 predetermined by the agreement.

The starting time of the second time period may be equal to or later than the ending time of the first time period. For example, the starting time of the second time period may be the end time of the first time period, or the starting time of the second time period may be after the end time of the first time period and at an interval from the end time of the first time period. Time domain position of several slots/symbols. For example, as shown in any of Figures 6b to 6d, the starting time of the second time period is a time domain that is after the end time of the first time period and has a time interval between the end time of the first time period and the end time of the first time period. Location.

For example, the terminal monitoring the first scheduling information in the second time period 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.

The monitoring parameters in the second time period may include: one or more types of information including search space configuration, CORESET configuration, and RNTI corresponding to the first scheduling information. The configuration of the search space may include one or more of the monitoring period of the search space, the DCI format of downlink control information that needs to be monitored, the number of candidates that need to be monitored, and the aggregation level that needs to be monitored. The relevant definitions of each parameter may refer to the existing description, and the method for the terminal to monitor the first scheduling information according to the monitoring parameters of the second time period may refer to the existing description, which will not be described again.

The monitoring parameters in the second time period can also be determined by the terminal according to the configuration of the network device. For example, the network device broadcasts the monitoring parameters in the second time period in a broadcast message, and the terminal receives the broadcast message broadcast by the network device. Obtain the monitoring parameters in the second time period from the broadcast message.

It should be noted that in various embodiments of the present application, the monitoring parameters in the second time period, the duration of the second time period, the starting time and/or the ending time of the second time period may be included in the same broadcast message configured to The terminal may also be configured in different broadcast messages to the terminal.

Step 505: When the conditions for stopping monitoring are met, the terminal stops monitoring the first scheduling information.

Among them, the conditions for stopping monitoring may include the following condition (1) or condition (2):

Condition (1): The first downlink data is successfully received within the second time period.

For example, if the terminal monitors the first scheduling information within the second time period, receives the first downlink data according to the time-frequency resource location indicated by the first scheduling information, and the first downlink data is successfully received through verification, then Stop monitoring the first scheduling information to save energy consumption of the terminal.

Taking Figure 6b as an example, if the terminal successfully receives the time-frequency resource position indicated by the monitored first scheduling information at a certain time point between time t1 and time t2, such as the intermediate time between time t1 and time t2, If the first downlink data is received, the terminal may stop monitoring the first scheduling information from this time point.

Condition (2), the end of the second time period.

For example, the terminal has not monitored the first scheduling information in the second time period, or the terminal has monitored the first scheduling information in the second time period, but according to the time and frequency indicated by the first scheduling information in the second time period, If the location information does not receive the first downlink data, the terminal may stop monitoring the first scheduling information at the end of the second time period.

The conditions for stopping monitoring may also include condition (1) and condition (2). When condition (1) is met within the second time period, monitoring will be stopped. After the second time period is over, monitoring will be stopped.

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

Applying the method shown in Figure 5, the terminal may not monitor the scheduling information for scheduling the first downlink data within the first time period after sending the first message including uplink data, but monitor again after the first time period. Scheduling information used to schedule the first downlink data. In this way, by setting the first time period, the sleep time between the terminal sending the first message and monitoring the scheduling information can be increased, thereby reducing the power consumption of the terminal.

For example, as shown in Figure 6a, a first time period is set: time t0 to time t1. At time t0 after the terminal sends the first message to the network device, it starts the first timer corresponding to the first time period, turns off its own radio frequency module while the first timer is running, and does not monitor the first scheduling information until the first timer ends. . Turn on its own radio frequency module at t1 when the first timer ends, and monitor the first scheduling information. Alternatively, the starting time of the first time period in Figure 6a can also be later than time t0, and be separated from time t0 by one or more time slots/symbols; or, the starting time of the first time period in Figure 6a can also be Equal to or later than the time when successful transmission of the first message is determined (not shown in Figure 6a).

For another example, as shown in Figure 6b, the first time period is set: time t0 to time t1, and the second time period is: time t1 to time t2. At time t0 after the terminal sends the first message to the network device, it starts the first timer corresponding to the first time period, turns off its own radio frequency module while the first timer is running, and does not monitor the first scheduling information until the first timer ends. . At time t1 when the first timer ends, start the second timer corresponding to the second time period, turn on its own radio frequency module during the running of the second timer, and monitor the first scheduling information. Alternatively, the starting time of the first time period in Figure 6b can also be later than time t0, and be separated from time t0 by one or more time slots/symbols, or the starting time of the first time period in Figure 6b can also be Equal to or later than the time when the first message is determined to be successfully sent (not shown in Figure 6b); the starting time of the second time period in Figure 6b can also be later than time t1, and is separated from time t1 by one or more time slots/ symbol.

For another example, as shown in Figure 6c, the first time period is set: time t0 to time t1, and the second time period is: time t2 to time t3. At time t0 after the terminal sends the first message to the network device, it starts the first timer corresponding to the first time period, turns off its own radio frequency module while the first timer is running, and does not monitor the first scheduling information until the first timer ends. . At time t2 after the first timer ends, start the second timer corresponding to the second time period, turn on its own radio frequency module during the running of the second timer, and monitor the first scheduling information. Alternatively, the starting time of the first time period in Figure 6c can also be later than time t0, and be separated from time t0 by one or more time slots/symbols, or the starting time of the first time period in Figure 6c can also be Equal to or later than the time when successful transmission of the first message is determined (not shown in Figure 6c).

For another example, as shown in Figure 6d, three time periods are set: the first time period: time t1 to time t2, the second time period: time t3 to time t4, and the third time period: time t0 to time t1. At time t0 after the terminal sends the first message to the network device, it starts the third timer corresponding to the third time period, turns on its own radio frequency module during the running of the third timer, and monitors the information about scheduling the retransmission of the first message. It is detected and determined that the first message is successfully sent, and the first timer corresponding to the first time period is started at time t1 after the first message is successfully sent. Turn off its own radio frequency module while the first timer is running, and do not monitor the first scheduling information until the first timer ends. At time t3 after the first timer ends, start the second timer corresponding to the second time period, turn on its own radio frequency module during the running of the second timer, and monitor the first scheduling information. Alternatively, the starting time of the third time period in Figure 6d can also be later than time t0 and separated from time t0 by one or more time slots/symbols. The starting time of the second time period in Figure 6d can also be time t2, no limit.

The following is combined with the scenario shown in Figure 7 where users send and receive WeChat messages through mobile phones. The terminal is a mobile phone and the network equipment 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 upper layers of the base station receive the uplink data. The high-level feedback information corresponding to the uplink data is generated and sent to the bottom layer of the base station. The time for coding, modulating and sending the high-level feedback information is 200ms. The transmission delay between the mobile phone and the base station is 50ms. As an example, the monitoring method shown in Figure 5 is described.

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

The base station sends a broadcast message, which includes relevant configurations in the first time period, relevant configurations in the second time period, and monitoring parameters in the second time period. The relevant configuration of the first time period includes the duration of the first time period, the starting moment and/or the ending moment of the first time period, and the relevant configuration of the second time period includes the duration of the second time period, the starting point of the second time period. start time and/or end time. The duration of the first time period can be set to 100ms, and the duration of the second time period can be set to 100ms.

The mobile phone monitors the broadcast message, obtains 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 the third time period corresponding to the first time period based on the obtained information. A timer and a second timer corresponding to the second time period.

In a specific scenario, when a user sends a WeChat message through a mobile phone, the WeChat message sent by the user only has one number or one text, and the amount of data is relatively small. The terminal device does not need to enter the connected state, and can send small packet data in the non-connected state. Send this WeChat message with a relatively small amount of data. At this time, the mobile phone generates the data message corresponding to the WeChat message, sends msgA to the base station, carries the data message in msgA, and starts the first timer after sending msgA, and does not monitor the time used to schedule msgB during the running of the first timer. Scheduling information.

The bottom layer of the base station receives the msgA, decodes and demodulates the msgA to obtain the data message, and sends the data message to the upper layer of the base station. The higher layer of the base station forwards it to the WeChat server, and the WeChat server parses the WeChat message and Send a high-level feedback message. The upper layer of the base station obtains the high-level feedback information from the server, such as "message sent successfully", and sends the high-level feedback information to the bottom layer of the base station. The bottom layer of the base station encodes and modulates the high-level feedback information to obtain downlink data, and sends the downlink data to the base station. The bottom layer determines that the response message received from msgA is carried in msgB, and sends the scheduling information used to schedule msgB and msgB to the mobile phone.

After the first timer stops, the mobile phone starts the second timer and starts monitoring the scheduling information of the msgB according to the monitoring parameters in the second time period. If the scheduling information of the scheduled msgB is monitored during the running of the second timer, the monitoring is stopped, and the msgB is received at the time-frequency resource position indicated by the scheduling information of the scheduled msgB, and the high-level feedback information is obtained from the received msgB. Present the received high-level feedback information: "Message sent successfully" to the user. Of course, the "message sent successfully" shown in Figure 7 is only an example, and the message may not be displayed or the message may be displayed successfully or in other display ways to indicate successful sending.

Compared with the existing monitoring method where the mobile phone monitors the scheduling information for scheduling msgB after sending msgA, in the existing monitoring method, the mobile phone needs about 200ms to monitor the scheduling information for scheduling msgB, and the method shown in Figure 7 The time for monitoring scheduling information is about 100ms, which shortens the monitoring time and lengthens the sleep time of the mobile phone, thereby reducing the power consumption of the mobile phone.

The methods shown in Figure 5 and Figure 7 take as an example a response message for receiving the first message determined by the bottom layer of the network device and high-level feedback information corresponding to the uplink data determined by the high-level layer of the network device to the terminal. The method of monitoring scheduling information by an active terminal is explained. However, in actual applications, after the network device receives the first message including uplink data, the following three situations may occur: Situation 1: After the network device receives the first message including uplink data, there happens to be downlink services that require terminal switching to the connected state. At this time, the network device can send the response message determined by the bottom layer of the network device to the terminal as soon as possible after receiving the first message, and use the high-level feedback information corresponding to the uplink data determined by the high-level layer of the network device as normal downlink data. , sent to the terminal when the terminal switches to the connected state. Case 2: After the network device receives the first message including uplink data, the network device includes the response message determined by the bottom layer of the network device to receive the first message and the high-level feedback information corresponding to the uplink data determined by the high-level layer of the network device in the same downlink data. sent to the terminal. Scenario 3: After receiving the first message including uplink data, the network device first sends the response message determined by the lower layer of the network device to the terminal as soon as possible, and then sends the response message corresponding to the uplink data determined by the higher layer of the network device. The high-level feedback information is then scheduled to the terminal, and at the same time, the terminal is instructed to monitor the scheduling information for scheduling the high-level feedback information within a certain period of time after monitoring the scheduling information after the scheduling response message.

For the terminal, it is unknown under what circumstances the network equipment will send downlink data. In order to ensure that the terminal can receive the downlink data sent by the network equipment when it is in the idle state or inactive state, and at the same time reduce the time required for terminal monitoring to schedule downlink data. Regarding the power consumption of scheduling information, embodiments of the present application also provide a monitoring method that sets two time periods for the terminal. In one of the time periods, the terminal monitors the scheduling information of the response message used to schedule the bottom layer feedback of the network device, and in the other time period, the terminal monitors the power consumption of the scheduling information. Monitor the scheduling information of high-level feedback information for scheduling network equipment within a period of time. Specifically, the method can be shown in Figure 8.

Figure 8 is a monitoring method provided by an embodiment of the present application. The method is executed by a terminal, and the terminal is in an idle state or an inactive state. As shown in Figure 8, the method may include:

Step 801: The terminal sends a first message to the network device.

The relevant description of the first message and the execution process of step 801 may refer to step 501. For example, the first message is sent to the network device through msg3 or msgB or a configuration scheduling message, which will not be described in detail.

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

Step 802a: The network device sends the first scheduling information and the 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 and the first downlink data to the terminal may include: the network device sending the first scheduling information to the terminal through the PDCCH, and sending the first downlink to the terminal at the time-frequency resource position indicated by the first scheduling information. row data.

The first downlink data described in step 802a is different from the first downlink data described in step 502. The first downlink data described in step 802a may include a response message 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. Corresponding to the terminal sending the first message, the network device may refer to the above methods (2.1) to (2.3) to send the first downlink data to the terminal through msg4 in the four-step random access process, or, through the two-step msgA during the random access process sends the first downlink data to the terminal, or sends the first downlink data to the terminal by configuring a scheduling response.

If the network device sends the first scheduling information and the first downlink data to the terminal, it means that the network device determines not to send the high-level feedback information corresponding to the uplink data determined by the high-level layer of the network device and the response message determined by the bottom layer together to the terminal. , it is likely that when the terminal switches to the connected state, the high-level feedback information corresponding to the uplink data will be sent to the terminal. After monitoring the first scheduling information, the terminal does not need to monitor the scheduling information in the idle state or inactive state. On the contrary, if the network device wishes to send high-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 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 and the first downlink data to the terminal may include: the network device sending the first scheduling information to the terminal through the PDCCH, and sending the first downlink to the terminal at the time-frequency resource position indicated by the first scheduling information. row data.

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

The first downlink data described in step 802b is different from the first downlink data described in step 502 and step 802a. The first downlink data described in step 802b may include the underlying determination of the network device. response messages and instructions. 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 the fifth time period after monitoring the first scheduling information, and may also be used to indicate monitoring parameters and other information in the fifth time period, such as: the fifth time period the duration, the starting time and/or the ending time of the fifth time period.

Corresponding to the terminal sending the first message, the network device may refer to the above methods (2.1) to (2.3) to send the first downlink data to the terminal through msg4 in the four-step random access process, or, through the two-step msgA during the random access process sends the first downlink data to the terminal, or sends the first downlink data to the terminal by configuring a scheduling response.

In step 802b, the network device decouples and sends the response message determined by the lower layer of the network device and the high-level feedback information determined by the higher layer of the network device. The time at which the network device sends the first scheduling information is earlier than the time at which the network device sends the second scheduling information. For example, the time when the network device sends the first scheduling information is determined by the bottom layer of the network device, and the time when the network device sends the second scheduling information can be determined by the high layer of the network device. It depends on the time it takes for the bottom layer to receive and process feedback information from the top layer.

Among them, the relevant description of the upper layer of the network device and the lower layer of the network device can be referred to as shown in Figure 2. The process of the upper layer of the network device generating high-level feedback information and the process of the lower layer of the network device encoding and modulating the high-level feedback information can be referred to the existing Technology will not be described in detail.

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

The content of the second downlink data described in step 802c is different from that of the second downlink data described in step 802b. The second downlink data described in step 802c may not only include high-level feedback information corresponding to the uplink data, but also include network The underlying response message of the device. Corresponding to the terminal sending the first message, the network device may refer to the above methods (2.1) to (2.3) to send the second downlink data to the terminal through msg4 in the four-step random access process, or, through the two-step random access msgA during the access process sends the second downlink data to the terminal, or sends the second downlink data to the terminal by configuring a scheduling response.

That is, in step 802c, the network device includes the response message determined by the lower layer of the network device and the high-level feedback information determined by the higher layer of the network device in the second downlink data and sends it to the terminal. At this time, the time for the network device to send the second scheduling information may be determined based on the time for the higher layer of the network device to determine the higher layer feedback information to the lower layer of the network device to receive and process the higher layer feedback information.

Step 803: The terminal monitors the first scheduling information within the fourth time period after sending the first message.

The fourth time period may be used to limit the duration for which the terminal monitors 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 length 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 configuration of the network device. For example, the network device combines the length of the fourth time period, the starting time and/or the ending time of the fourth time period. /or the end time includes being broadcast in a broadcast message. The terminal receives the broadcast message and obtains the duration of the fourth time period, the start time and/or the end 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 can also be pre-specified by the agreement without limitation.

For example, the terminal may configure a fourth timer according to the length of the fourth time period, the starting time and/or the ending time of the fourth time period, and the length of the fourth timer is equal to the length of the fourth time period. The start time of the timer corresponds to the starting moment 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 the validity period/running period of the fourth timer.

The starting time of the fourth time period is related to the ending time of sending the first message. In one possible design, the starting moment of the fourth time period may be equal to or later than the ending moment of sending the first message for the first time. For example, the starting moment of the fourth time period may be the ending moment of sending the first message for the first time. Alternatively, the starting time of the fourth time period may be a time domain position that is several time slots/symbols after the end time of first sending the first message and separated from the end time of first sending the first message. As shown in Figure 9a, the starting time of the fourth time period is the end time t0 of sending the first message.

In another possible design, in order to ensure that the first message is successfully sent, the starting time of the fourth time period may be set to be equal to or later than the time when the first message is determined to be successfully sent. For example, the starting moment of the fourth time period may be the moment when it is determined that the first message is successfully sent, or the starting moment of the fourth time period is after the moment when it is determined that the first message is successfully sent, and after the moment when it is determined that the first message is successfully sent. The time domain position of several slots/symbols apart. As shown in Figure 9b, the starting time of the fourth time period is the time t1 when it is determined that the first message is successfully sent.

The terminal may determine whether the first message is successfully sent by monitoring information scheduling resend of the first message within the fourth time period. The relevant description of the fourth time period and the specific implementation process of determining whether the first message is successfully sent may refer to the description in step 403, and will not be described again.

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

The monitoring parameters in the fourth time period may include: one or more information among the search space configuration, CORESET configuration, and RNTI corresponding to the first scheduling information. The configuration of the search space may include one or more of the monitoring period of the search space, the DCI format of downlink control information that needs to be monitored, the number of candidates that need to be monitored, and the aggregation level that needs to be monitored. The relevant definitions of each parameter may refer to the existing description, and the method for the terminal to monitor the first scheduling information according to the monitoring parameters of the fourth time period may refer to the existing description, which will not be described again.

The monitoring parameters in the fourth time period can also be determined by the terminal according to the configuration of the network device. For example, the network device broadcasts the monitoring parameters in the fourth time period in a broadcast message, and the terminal receives the broadcast message broadcast by the network device. The monitoring parameters in the fourth time period are obtained from the broadcast message.

It should be noted that in various embodiments of the present application, the monitoring parameters in the fourth time period, the duration of the fourth time period, the starting time and/or the ending time of the fourth time period may be included in the same broadcast message configured to The terminal can also be configured in different broadcast messages to the terminal without limitation.

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

Exemplarily, when the terminal determines that the first scheduling information is not monitored within the fourth time period, it monitors the second scheduling information within the fifth time period after the fourth time period; or, the terminal determines that the first downlink data includes an indication. information, and the indication information is used to indicate that when the second scheduling information is monitored within the fifth time period, the second scheduling information is monitored within the fifth time period according to the indication information. If the terminal determines that the first scheduling information is monitored within the fourth time period and the first downlink data received according to the time-frequency resource location indicated by the first scheduling information does not include indication information, it will not During the time period, the second scheduling information is monitored.

The fifth time period may be used to limit the duration for which the terminal monitors the second scheduling information. The fifth time period corresponds to the time when the higher layer of the network device sends higher layer feedback information to the terminal. In a possible design, the length of the fifth time period, the starting time and/or the ending time of the fifth time period can be determined by the terminal according to the configuration of the network device. For example, the network device determines the length of the fifth time period, the starting time and/or the ending time of the fifth time period. The start time and/or end time of the time period include being broadcast in the broadcast message. The terminal receives the broadcast message and obtains the duration of the fifth time period, the start time and/or the end time of the fifth time period from the broadcast message. In another possible design, the duration of the fifth time period, the starting time and/or the ending time of the fifth time period may be included in the above indication information and configured for the terminal. In another possible design, the length of the fifth time period, the starting time and/or the ending time of the fifth time period can also be pre-specified by the agreement and are not limited.

For example, the terminal may configure the fifth timer according to the length of the fifth time period, the starting time and/or the ending time of the fifth time period, and the length of the fifth timer is equal to the length of the fifth time period. The start time of the timer corresponds to the starting moment of the fifth time period. After the terminal sends the first message, the fifth timer is started, and the second scheduling information is monitored during the validity period/running period of the fifth timer.

The starting time of the fifth time period may be equal to or later than the ending time of the fourth time period. For example, the starting time of the fifth time period may be the end time of the fourth time period, or the starting time of the fifth time period may be after the end time of the fourth time period and at an interval from the end time of the fourth time period. Time domain position of several slots/symbols.

For example, the terminal monitoring the second scheduling information in the fifth time period may include: the terminal determines the monitoring parameters in the fifth time period, and monitors the second scheduling information based on the monitoring parameters in the fifth time period.

The monitoring parameters in the fifth time period may include: one or more information among the search space configuration, CORESET configuration, and RNTI corresponding to the second scheduling information. The configuration of the search space may include one or more of the monitoring period of the search space, the DCI format of downlink control information that needs to be monitored, the number of candidates that need to be monitored, and the aggregation level that needs to be monitored. The relevant definitions of each parameter may refer to the existing description, and the method for the terminal to monitor the second scheduling information according to the monitoring parameters of the fifth time period may refer to the existing description, which will not be described again.

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.

Among them, the monitoring parameters in the fifth time period can also be determined by the terminal according to the configuration of the network device. For example, the network device broadcasts the monitoring parameters in the fifth time period including the broadcast message, and the terminal receives the broadcast message broadcast by the network device. The monitoring parameters in the fifth time period are obtained from the broadcast message; or, the network device includes the monitoring parameters in the fifth time period in the above indication information and configures them to the terminal.

It should be noted that in various embodiments of the present application, when the monitoring parameters in the fifth time period, the duration of the fifth time period, the start time and/or the end time of the fifth time period are configured to the terminal through a broadcast message, The monitoring parameters in the fifth time period, the duration of the fifth time period, the starting time and/or the ending time of the fifth time period may be included in the same broadcast message and configured to the terminal, or may be included in different broadcast messages. To the terminal, no restrictions.

Further, in order to prevent the terminal from monitoring the second scheduling information indefinitely, the method shown in Figure 8 may also include: stopping monitoring the second scheduling information when the conditions for stopping monitoring are met.

The conditions for stopping monitoring may refer to the above-mentioned step 504, and may include successfully receiving the second downlink data within the fifth time period; or the end of the fifth time period.

For example, if the terminal monitors the second scheduling information within the fifth time period, receives the second downlink data according to the time-frequency resource location indicated by the second scheduling information, and the second downlink data is successfully received through verification, then the monitoring is stopped. The second scheduling information is used to save energy consumption of the terminal. Alternatively, if the terminal has not monitored the second scheduling information within the fifth time period, the terminal stops monitoring the second scheduling information at the end of the fifth time period. Alternatively, if 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 location information indicated by the second scheduling information in the fifth time period, the terminal can monitor the second downlink data in the fifth time period. When finished, stop monitoring the second scheduling information.

Applying the method shown in Figure 8, after sending uplink data, the terminal can monitor the first scheduling information in the fourth time period and the second scheduling information in the fifth time period, that is, set a specific time period, and at a specific time Monitor scheduling information within a segment to avoid the problem of large power consumption caused by indefinite monitoring of scheduling information. At the same time, in the method described in the seventh aspect, by setting two time periods for monitoring scheduling information, the terminal monitors the scheduling information for scheduling downlink data in two consecutive time periods, ensuring that the network equipment can flexibly send downlink data. down, the accuracy of receiving downlink data.

For example, as shown in Figure 9a, a fourth time period is set: time t0 to time t1, and a fifth time period: time t2 to time t3. At time t0 after the terminal sends the first message to the network device, it starts the fourth timer corresponding to the fourth time period. During the running of the fourth timer, it can turn on its own radio frequency module and monitor the first scheduling information until the end of the fourth timer. . If the first scheduling information is monitored during the running of the fourth timer and the first downlink data is received according to the first scheduling information, the second scheduling information is not monitored within the fifth time period.

For another example, as shown in Figure 9b, a fourth time period is set: time t0 to time t1, and a fifth time period: time t2 to time t3. At time t0 after the terminal sends the first message to the network device, it starts the fourth timer corresponding to the fourth time period. During the running of the fourth timer, it can turn on its own radio frequency module and monitor the first scheduling information until the end of the fourth timer. . If the first scheduling information is not detected during the running of the fourth timer, at time t2 after the end of the fourth timer, the fifth timer corresponding to the fifth time period is started, and its own timer is started during the running of the fifth timer. The radio frequency module monitors the second scheduling information.

For another example, as shown in Figure 9c, a fourth time period is set: time t0 to time t1, and a fifth time period: time t2 to time t3. At time t0 after the terminal sends the first message to the network device, it starts the fourth timer corresponding to the fourth time period. During the running of the fourth timer, it can turn on its own radio frequency module and monitor the first scheduling information until the end of the fourth timer. . If the first scheduling information is monitored during the running of the fourth timer, and the first downlink data is received according to the first scheduling information, and the first downlink data includes instructions for the terminal to monitor the second scheduling within the fifth time period According to the instruction information of the information, the terminal starts the fifth timer corresponding to the fifth time period at time t2 according to the instruction information, turns on its own radio frequency module during the operation of the fifth timer, and monitors the second scheduling information.

The following is combined with the scenario shown in Figure 10 where users send and receive WeChat messages via mobile phones. The terminal is a mobile phone and the network equipment 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, the upper layers of the base station , first feed back the bottom-layer determined response message to the terminal as soon as possible, then generate high-level feedback information corresponding to the uplink data, and send the high-level feedback information to the terminal. As an example, the monitoring method shown in Figure 8 is described.

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

The base station sends a broadcast message, which includes relevant configurations in the fourth time period, relevant configurations in the fifth time period, and monitoring parameters in the fifth time period. The relevant configuration of the fourth time period includes the duration of the fourth time period, the starting moment and/or the ending moment of the fourth time period, and the relevant configuration of the fifth time period includes the duration of the fifth time period, the starting point of the fifth time period. start time and/or end time. The duration of the fourth time period can be set to 50ms, and the duration of the fifth time period can be set to 100ms.

The mobile phone monitors the broadcast message, obtains 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 from the broadcast message, and configures the fourth time period corresponding to the fourth time period based on the obtained information. Four timers and a fifth timer corresponding to the fifth time period.

In a specific scenario, when a user sends a WeChat message through a mobile phone, the WeChat message sent by the user only has one number or one text, and the amount of data is relatively small. The terminal device does not need to enter the connected state, and can send small packet data in the non-connected state. Send this WeChat message with a relatively small amount of data. At this time, the mobile phone generates the data message corresponding to the WeChat message, sends msgA to the base station, carries the data message in msgA, starts the fourth timer after sending msgA, and monitors the scheduling information used to schedule msgB during the running of the fourth timer. .

The bottom layer of the base station receives the msgA and first feeds back the response message and indication information to the terminal. For example, the response message and the indication information are carried in msgB, and the scheduling information for scheduling msgB and msgB are sent to the mobile phone. At the same time, the msgA is decoded and demodulated to obtain the data message, and the data message is sent to the higher level of the base station. The upper level of the base station forwards it to the WeChat server. The WeChat server parses the WeChat message and sends a high-level feedback information. The high-level layer of the base station obtains the high-level feedback information from the server, such as "message sent successfully", and sends the high-level feedback information to the bottom layer of the base station. The bottom layer of the base station encodes and modulates the high-level feedback information to obtain downlink data, and sends it to the mobile phone for Scheduling information and downlink data for scheduling the downlink data.

During the operation of the fourth timer, the mobile phone monitors the scheduling information for scheduling msgB, receives indication information at the time-frequency resource location indicated by the scheduling information for scheduling msgB, starts the fifth timer according to the indication information, and starts the fifth timer according to the indication information. Monitoring parameters within five time periods monitor and schedule the scheduling information of downlink data. If the scheduling information for scheduling downlink data is monitored during the running of the fifth timer, the monitoring is stopped, and the downlink data is received at the time-frequency resource position indicated by the scheduling information for scheduling downlink data, and the upper layer is obtained from the received downlink data. Feedback information: present the received high-level feedback information: "Message sent successfully" to the user. Of course, the "message sent successfully" shown in Figure 10 is only an example, and the message may not be displayed or the message may be displayed successfully or in other display ways to indicate successful sending.

Compared with the existing monitoring method where the mobile phone monitors the scheduling information for scheduling msgB after sending msgA, in the existing monitoring method, the mobile phone needs about 200ms to monitor the scheduling information for scheduling including response messages and high-level feedback information. The monitoring method shown in Figure 10 includes two monitoring times, and the total time for monitoring 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 methods shown in Figures 5 to 10, in order to better reduce the power consumption of the terminal, the search space for scheduling information of small packet data can be set to be different from the first search space, such as : Set the number of search spaces for scheduling information of small packet data to a smaller number to reduce the number of blind checks and reduce the power consumption of the terminal. Or, set the monitoring period of the search space of the scheduling information for scheduling small packet data to be different from the first search space, for example: set the monitoring period of the search space of the scheduling information of small packet data to be longer, and set it to 5 time slots/10 slots reduce the frequency of terminal monitoring of scheduling information, thereby reducing the power consumption of the terminal.

The first search space may be a search space used for monitoring scheduling information for scheduling non-small packet data. The first search space may be called a random access search space (ra-search space). The search space used for scheduling scheduling information of small packet data may be called random access search space small data (ra-search space small data) or small packet data random access search space. It may also be called a dedicated search space, etc., without limitation. .

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

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

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

For example, taking the four-step random access process, the search space used to schedule the scheduling information of small packet data is called a dedicated search space. As shown in Figure 11a, the terminal can be in the random access search space (ra-search space). Monitor the scheduling information used to schedule msg2 and monitor the scheduling information used to schedule msg3 in the ra-search space. After the terminal sends msg3 carrying small packet data, the terminal can switch to the dedicated search space to monitor the scheduling information used to schedule msg4. . Or, as shown in Figure 11b, the terminal can directly use the dedicated preamble sequence resource to send msg1, and after sending msg1, start monitoring the scheduling information for scheduling msg2/msg3/msg4 in the dedicated search space.

As another example, taking the four-step random access process, the search space used to schedule the scheduling information of small packet data is called a dedicated search space. As shown in Figure 11c, the terminal can apply ra-search space in the ra-search space. The monitoring cycle monitoring is used to schedule the scheduling information of msg2. The monitoring cycle monitoring of ra-search space is used to schedule the scheduling information of msg3 in ra-search space. After the terminal sends msg3 carrying small packet data, the terminal can switch to dedicated In the search space, the monitoring cycle of the dedicated search space is used to monitor the scheduling information used to schedule msg4. Or, as shown in Figure 11d, the terminal can directly use the dedicated preamble sequence resource to send msg1, and after sending msg1, start to apply the monitoring cycle monitoring of the dedicated search space for scheduling msg2/msg3/msg4 in the dedicated search space. scheduling information.
