Description

Communication method and communication device

Technical Field

The present application relates to the field of wireless communications, and in particular, to a communication method and a communication apparatus.

Background

With the continuous development of wireless communication technology, in order to meet the increasing communication service demand, a fifth generation (5G) mobile communication technology (also referred to as New Radio (NR) technology) has been proposed. Services supported by the 5G mobile communication technology are very various, such as enhanced mobile broadband (eMBB) -oriented services, ultra-reliable low-latency communication (URLLC) services, and the like. Recently, a simplified NR system, called NR-light system, has been proposed. The NR-light system has higher data rate and reliability compared to enhanced machine type communication (eMTC). In practical application, the NR-light system and the enhanced mobile broadband system can be nested with each other, so that adaptive communication services can be provided for terminal devices with different service requirements. Since the available time of the terminal device is an important factor affecting the user experience of the terminal device, how to reduce the power consumption of the terminal device is a current research focus.

In the prior art, a network device usually notifies a terminal device of a result of whether some system events occur, so as to avoid the terminal device from executing some invalid operations, thereby reducing power consumption of the terminal device. For example, a network device in the eMBB system may inform a terminal device in advance whether system information sent by the terminal device is updated, so that the terminal device does not need to repeatedly acquire the same system information from the network device when the system information is not updated, thereby reducing power consumption of the terminal device. However, in the existing method, the network device may respectively indicate various different system events through corresponding indication information, and as the number of system events that need to be indicated increases, the indication information may generate a large amount of signaling overhead, which reduces the utilization rate of communication resources.

Detailed Description

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: for example, a communication system in which an NR-light system and an eMBB system are nested, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a fifth generation (5th generation, 5G) system, a New Radio (NR), or the like.

Terminal equipment in the embodiments of the present application may refer to user equipment, access terminals, subscriber units, subscriber stations, mobile stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user devices. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited in this embodiment.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present disclosure. As can be seen from fig. 1, the communication system comprises a network device and a user equipment. The network device can establish connection with the terminal device through wired connection, wireless connection or other connection modes. Of course, it is understood that the communication system may include one or more network devices and one or more terminal devices (e.g., terminal devices 1 to 5 in fig. 1). In the communication system shown in fig. 1, the network device usually notifies the terminal device of the result of whether some system events occur, so as to avoid the terminal device performing some invalid operations, thereby reducing the power consumption of the terminal device. For example, the network device informs the terminal device whether the system information sent by the terminal device is updated or not through the indication information, so that the terminal device does not need to repeatedly acquire the same system information from the network device under the condition that the system information is not updated, and the power consumption of the terminal device is reduced. However, since the network device may respectively indicate various system events through the corresponding indication information, the indication information may generate a large amount of signaling overhead as the number of system events that need to be indicated increases, thereby reducing the utilization rate of communication resources.

Therefore, the technical problems mainly solved by the embodiments of the present application are: how to reduce the signaling overhead generated by the indication information and improve the utilization rate of the communication resources.

Example one

Referring to fig. 2, fig. 2 is a flowchart illustrating a communication method according to an embodiment of the present disclosure. The communication method is applicable to the communication system shown in fig. 1. In this embodiment of the present application, the network device needs to indicate whether each system event in M system events of the terminal device occurs. As can be seen from fig. 2, the method comprises the following steps:

s10, the network device determines the indication information.

In some possible implementation manners, the network device may determine whether N system events in the first associated event group occur according to current system state information, a system log, and the like, and further determine states of N indication identifiers included in the indication information. Here, the N indication flags are respectively used to indicate whether or not a system event included in different associated event groups occurs in different flag states. It is to be understood that the above N states of the indicator flag in a specific flag state may be used to indicate whether the system event included in the first associated event group occurs. The first associated event group is composed of N associated system events in M system events, and M is greater than N.

It should be explained herein that in the embodiments of the present application, the association between two system events means whether a first system event of the two system events occurs or not determines whether the occurrence or non-occurrence of a second system event needs to be indicated. The N associated system events refer to that at least two associated system events exist in the N system events, or that at least one first system event exists in the N system events, and whether the occurrence of the first system event determines whether the occurrence or non-occurrence of N-1 system events other than the first system event needs to be indicated.

Optionally, in practical applications, before determining the identifier states of the N indicator identifiers, the network device may determine, according to whether each system event in the M system events is associated with each other, one or more associated event groups at least including the first associated event group. Here, each associated event group is composed of N associated system events. It should be noted that, taking the first associated event group as an example, after determining the first associated event group, the network device may determine whether each system event in N associated system events included in the first associated time group occurs according to current system state information, a system log, and the like. If a certain system event occurs, the indication identifier corresponding to the system event in the N indication identifiers may be set to be in a first identifier state (for convenience of understanding and distinction, the description is replaced with the first identifier state hereinafter). If a certain system event does not occur, the indication identifier corresponding to the system event in the N indication identifiers may be set to be in a second identifier state (for convenience of distinction, the description is replaced with the second identifier state hereinafter). After the network device judges the N system events in the first associated event group N times, the identifier state corresponding to each of the N indicator identifiers can be determined. It should be noted that the first identifier state and the second identifier state are only used to indicate that a value of a certain identifier is different or an implementation form is different, and do not have other limiting functions.

Optionally, in an optional implementation, the N indicators may include a first indicator and a second indicator. The M system events include a first system event, a second system event, and a third system event. The first system event is associated with the second system event, and the first system event is associated with the third system event. Specifically, a second system event may occur in the event that a first system event occurs. In the case that the first system event does not occur, the second system event does not occur, so that the second system event does not need to indicate whether the second system event occurs, and therefore whether the third system event occurs can be indicated. Thus, the network device may combine the first system event and the second system event into a first associated event group and the first system event and the third system event into a second associated event group. After determining the first event association and the second time association, the network device may determine whether the first system event occurs according to current system state information, a system log, and other information. If the network device determines that the first system event has occurred, the first indicator may be set to a first indicator state. Then, the network device may continue to determine whether the second system event occurs. If the network device determines that the second system event occurs, the second indication flag may be set to a first flag state, and if the network device determines that the second system event does not occur, the second indication flag may be set to a second flag state. If the network device determines that the first system event does not occur, the first indicator may be set to a second indicator state. Then, the network device may continue to determine whether the third system event occurs. If the network device determines that the third system event occurs, the second indication flag may be set to a first flag state, and if the network device determines that the third system event does not occur, the second indication flag may be set to a second flag state. That is to say, in a state that the first indication identifier is a first identifier, the first indication identifier and the second indication identifier are respectively used for indicating whether a first system event and a second system event occur. And under the condition that the first indication identifier is in a second identifier state, the first indication identifier and the second indication identifier are respectively used for indicating whether the first system event and the third system event in a second associated event group occur or not. Finally, the network device may determine the first indicator and the second indicator with known identifier states as the indication information.

Here, whether three system events occur or not is indicated through different states of the two indication marks, signaling overhead generated by indication information is saved, and the utilization rate of communication resources is improved.

It should be noted that, in the present application, a first type of terminal device may be a massive internet of things communication (mtc) terminal device, and a second type of terminal device may be another type of terminal device except for an mtc terminal, which is not limited in this application. In particular, the NR-light type terminal device may also be referred to as an mtc terminal device.

Optionally, in another specific implementation, the N indicators may further include a third indicator for indicating whether a fourth system event occurs. The first system event is not related to the first system event, the second system event is not related to the third system event. Similarly, after determining the states of the first indicator and the second indicator, the network device may further determine whether the fourth system event occurs according to information such as system state information and a system log. If the network device determines that the fourth system event occurs, the third indicator may be set to the first indicator state, and if the network device determines that the fourth system event does not occur, the third indicator may be set to the second indicator state.

Further, in the case where the NR-light system and the eMBB system are nested. The first system event may specifically be that the network device sends a system information block type — SIB1 corresponding to the first type of terminal device. Here, the first type of terminal device specifically refers to a terminal device under the NR-light system. The second system event is that the first system information of the first type of terminal equipment is updated within a first effective time. And the third system event is that the network equipment sends the PBCH (physical broadcast channel). Here, the first physical broadcast channel PBCH is used to carry second system information of the first type of terminal device. The fourth system event may be specifically that the third system information of the second type of terminal device is updated within the second valid time. Here, the second type of terminal device specifically refers to a terminal device under the eMBB system. It should be noted that the first system information and the second system information both refer to system information corresponding to the first type of terminal device. The second system information refers to a Master Information Block (MIB) of the first type terminal device carried in the first PBCH. This master information block contains necessary information related to cell camping, such as timing information, access information, configuration information of system information block type one (SIB 1), and the like. The first system information refers to system information corresponding to the terminal device except for the MIB. The first system information mainly includes SIB1 and other SIs except SIB1, etc., wherein the other SIs may include type two of system information blockA plurality of system information blocks such as (system information block type2, SIB2), system information block type three (system information block type3, SIB3), and the like. The third system information is system information of the second type terminal, specifically system information other than the MIB of the second type terminal device, and may mainly include SIB1 and other SI of the second type terminal device. The first PBCH is a physical broadcast channel introduced independently of the second PBCH. The method is mainly used for carrying additional system information for the first class terminal, such as configuration information of a control resource set (core set) of a physical downlink control channel PDCCH for scheduling the first class terminal device SIB 1. The second PBCH is a conventional PBCH (legacy PBCH) carried in a conventional synchronization signal and PBCH block (SS/PBCH block, legacy SSB). Here, the conventional SSB also carries Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS). In practice, the time and frequency resources of a conventional SSB are shown in Table 1-1. Table 1-1 is a conventional time and frequency resource table of an SSB provided in the embodiments of the present application. The table mainly shows the positions of Orthogonal Frequency Division Multiplexing (OFDM) symbols of the PSS, SSS, PBCH, etc. channels or signals with respect to the SSB starting position, and the subcarrier positions of the PSS, SSS, PBCH, etc. channels or signals with respect to the SSB starting position. Here, the first and second liquid crystal display panels are,

where v is based on the offset value of the cell identity,

In Table 1-1, PSS denotes the time-frequency resources of PSS, and SSS denotes the time-frequency resources of SSS. The PBCH represents the time-frequency resource of the second PBCH. A demodulation reference signal (DMRS) of the PBCH (i.e., DMRS for PBCH) indicates a DMRS for the second PBCH. Set to zero (Set to 0) tableAnd displaying and protecting time frequency resources. The guard time-frequency resources are not used for transmitting information. In other words, Set to 0 represents a time-frequency resource that is not used for transmitting information.

TABLE 1-1

In the following, the process of determining the indication information by the network device is briefly described with reference to the above 4 specific system events. It is assumed here that the first indicator is indicator bit a, the second indicator is indicator bit B, and the third indicator is indicator bit C.

In a specific implementation, if the network device does not support an NR-light or other types of NR mtc systems, it may indicate that the current cell does not support access to the first type of terminal by indicating not to send the SIB1 for the first type of terminal, and after the first type of terminal reads the identifier, the access procedure in the current cell may be stopped.

If the network device does not send the SIB1 corresponding to the first type terminal device, it indicates that the first type terminal device cannot access the network device, and it is not necessary to further indicate whether the first system information of the first type terminal device is updated. Therefore, the network device does not transmit the system event SIB1 corresponding to the first type of terminal device and the first system information of the first type of terminal device has updated the two system events to be associated within the first validity time. Here, the network device does not transmit the SIB1 corresponding to the first class terminal device may be understood as that the SSB currently transmitted by the network device does not include a control resource set (CORESET) 0, and the CORESET0 includes information of time domain resources, frequency domain resources, and the like occupied by the PDCCH. In practical applications, the network device may send multiple SSBs, and there may be several SSBs that do not include CORESET0, because these several SSBs are mainly used for Radio Resource Measurement (RRM). In the case that the network device does not transmit SIB1 corresponding to the first class of terminal devices, the network device may further indicate whether the first class of terminal devices transmits the first PBCH, so that the first class of terminal devices can acquire the scheduling information of the SSB including CORESET0 from the first PBCH more quickly when determining that the network device has transmitted the first PBCH. Thus, the network device transmitting the SIB1 corresponding to the first type of terminal device is associated with the system event that the network device transmits the first physical broadcast channel PBCH. Therefore, the network device may transmit the SIB1 corresponding to the first type terminal device and the first system information of the first type terminal device, which are updated by the network device within the first validity time to form the first association event group. Similarly, the network device may further form a second association event group by sending the SIB1 corresponding to the first type of terminal device by the network device and sending the first PBCH by the network device.

The network device may then first determine whether it has transmitted the SIB1 for the first terminal device based on system state information, system logs, etc. If the network device determines that it has sent the SIB1 of the first terminal device, the indication bit a may be set to 1. Then, the network device may continue to determine whether the first system information of the first type of terminal device is updated within the first valid time. If the network device determines that the first system information of the first class of terminal device is updated within the first valid time, the indicator bit B may be set to 1. If the network device determines that the first system information of the first class terminal device is not updated within the first valid time, the indicator bit B may be set to 0. Then, the network device may continue to determine whether the third system information of the second type of terminal device is updated within the second valid time. If the network device determines that the third system information of the second type of terminal device is updated within the second valid time, the indication bit C may be set to 1. If the network device determines that the third system information of the second type of terminal device is not updated within the second valid time, the indication bit C may be set to 0. That is, when the value of the indication bit a, the indication bit B, and the indication bit C included in the indication information is 100, it indicates that the network device has sent the SIB1 of the first type terminal device, and the first system information of the first type terminal device is not updated in the first valid time, and the third system information of the second type terminal device is not updated in the second valid time. When the value of the indication bit a, the indication bit B, and the indication bit C is 111, it indicates that the network device sends the SIB1 of the first type terminal device, and the first system information of the first type terminal device is updated in the first effective time, and the third system information of the second type terminal device is updated in the second effective time.

Alternatively, if the network device determines that it does not send the SIB1 of the first terminal device, the indication bit a may be set to 0. The network device may then determine whether it sends the first PBCH. If the network device determines that it has sent the first PBCH, the indication bit B may be set to 1. If the network device determines that it does not send the first PBCH, the indication bit B may be set to 0. Then, the network device may continue to determine whether the third system information of the second type of terminal device is updated within the second valid time. If the network device determines that the third system information of the second type of terminal device is updated within the second valid time, the indication bit C may be set to 1. If the network device determines that the third system information of the second type of terminal device is not updated within the second valid time, the indication bit C may be set to 0. That is, when the value of the indication bit a, the indication bit B, and the indication bit C is 000, it indicates that the network device does not send the SIB1 of the first type terminal device, and the network device also does not send the first PBCH, and the third system information of the second type terminal device is not updated in the second valid time. When the values of the indication bit a, the indication bit B, and the indication bit C are 011, it is indicated that the network device does not send the SIB1 of the first type terminal device, and sends the first PBCH, and the third system information of the second type terminal device is updated in the second valid time.

The network device can inform the terminal device whether the 4 system events occur or not through the three indication marks, and signaling overhead of indication information can be saved. Meanwhile, the terminal equipment can determine what operation should be further performed based on the result of whether the 4 system events occur, so that the terminal equipment can be prevented from performing invalid operations, and the power consumption of the terminal equipment is reduced.

Optionally, the triggering condition for the network device to determine the indication information may include multiple conditions. For example, the trigger condition may be that the network device detects that a preset indication period arrives. Alternatively, the triggering condition may be that the network device detects that the first system information or the third system information is updated. Alternatively, the triggering price adjustment may be an initial access request or a resynchronization request initiated by the network device detection terminal device. It is to be understood that the triggering condition for the network device to determine the indication information is not limited to the above examples, and the application is not limited in particular.

S20, the network device sends the indication information to the terminal device.

In some possible implementations, the network device may send the indication information through the second PBCH.

In a specific implementation, the N indicators include a first indicator, a second indicator, and a third indicator. The network device may send the first indicator, the second indicator and the third indicator through a reserved bit in a timing related bit carried on the second PBCH and a free bit in the main system information block MIB. Here, the timing related bits are a plurality of bits related to timing additionally added in the physical layer processing of the second PBCH, and generally include 8 bits, wherein the lower two bits belong to the reserved bits when the carrier frequency of the serving cell is less than 6GHz (i.e. in the frequency range 1). It should be noted that, in the present application, both the reserved bits and the spare bits are equivalent and may be used alternatively.

In some embodiments, specifically, the network device may send the first indication identifier and the second indication identifier through a reserved bit in a timing-related bit carried on the second PBCH, and send the third indication identifier through a free bit in a main system information block MIB carried on the second PBCH.

Of course, it can be understood that, in the initial access procedure or the resynchronization procedure, the network device may also send the indication information through a physical channel or system control signaling earlier than the second PBCH. The process of sending the indication information by the network device may also include other feasible implementation manners, and the application is not particularly limited.

And S30, the terminal equipment receives the indication information.

In some possible implementations, the terminal device may read the second PBCH to obtain the indication information.

In a specific implementation, when the N indicator marks include a first indicator mark, a second indicator mark, and a third indicator mark, the terminal device may read the lower two bits of the bits related to the timing carried on the second PBCH to obtain the first indicator mark and the second indicator mark. Meanwhile, the terminal device may further read an idle bit in the main system information block MIB in the second PBCH to obtain the third indicator.

Of course, it is understood that, in the initial access procedure or the resynchronization procedure, the terminal device may also obtain the indication information by reading a physical channel or system control signaling earlier than the second PBCH, which is not specifically limited in this application.

S40, the terminal device determines whether the system event included in the first associated event group occurs according to the state of the N1 indication flag in the above indication information.

In some feasible implementation manners, after the terminal device obtains the indication information, whether a system event included in different associated event groups occurs may be determined according to states of N indication identifiers included in the indication information. Here, the different association time groups include at least the first event association group.

In a specific implementation, it is assumed that the N indication identifiers include a first indication identifier, a second indication identifier, and a third indication identifier. After the terminal device obtains the first indication identifier, the second indication identifier and the third indication identifier, if the first indication identifier is determined to be in the first identifier state, it may be determined whether the first indication identifier and the second indication identifier are used for indicating whether a first system event and a second system event in a first associated event group occur. Therefore, the terminal device can continue to determine whether the second system event occurs. And if the terminal equipment determines that the second indication mark is in the first mark state, determining that the second system event occurs. And if the terminal equipment determines that the second indication identifier is in the second identifier state, determining that the second system event does not occur. If the terminal device determines that the first indication identifier is in the second identifier state, it may be determined whether the first indication identifier and the second indication identifier are used for indicating that the first system event and the third system event in the second associated event group occur. Therefore, the terminal device may continue to determine that the third system event described above has occurred. And if the terminal equipment determines that the second indication identifier is in the first identifier state, determining that the third system event occurs. And if the terminal equipment determines that the second indication identifier is in a second identifier state, determining that the third system event does not occur. And then, if the terminal device determines that the third indication identifier is in the first identifier state, it may determine that the fourth system event occurs, and if the terminal device determines that the third indication identifier is in the second identifier state, it may determine that the fourth system event does not occur.

Next, the process of the terminal device determining whether a system event occurs is briefly described with reference to the 4 specific system events described above. It is assumed here that the first indicator is indicator bit a, the second indicator is indicator bit B, and the third indicator is indicator bit C.

After acquiring the indicator bit a, the indicator bit B, and the indicator bit C included in the N indicator flags, if the terminal device determines that the value of the indicator bit a is 1, it may determine that the network device has sent the SIB1 of the first class terminal device. Meanwhile, the terminal device may determine whether the indication bit B is used to indicate that the first system information transmitted by the network device has been updated within the first validity time. If the terminal device determines that the indication bit B is 1, it may be determined that the first system information sent by the network device is updated within the first valid time. If the terminal device determines that the indication bit B is 0, it may be determined that the first system information sent by the network device is not updated within the first valid time. If the terminal device determines that the value of the indication bit a is 0, it may be determined that the network device does not send the SIB1 of the first type terminal device. Meanwhile, the terminal device may determine an indication bit B for indicating whether the network device transmits the first PBCH. If the terminal device determines that the indication bit B is 1, it may be determined that the network device has sent the first PBCH. If the terminal device determines that the indication bit B is 0, it may be determined that the network device does not send the first PBCH. And then, if the terminal device determines that the indication bit C is 1, the terminal device may determine that the third system information of the second type terminal device sent by the network device is updated within a second valid time. If the terminal device determines that the indication bit C is 0, it may be determined that the third system information of the second type of terminal device sent by the network device is not updated within the second valid time.

Optionally, when the current terminal device is the first type terminal device, the terminal may read only the indication bit a and the indication bit B from the second PBCH, and determine whether three system events, that the network device sends the SIB1 corresponding to the first type terminal device, the first system information of the first type terminal device is updated within the first valid time, and the network device sends the first physical broadcast channel PBCH, occur. When the current terminal device is the second class terminal, the terminal device may read the indication bit C from the second PBCH only, and determine whether the event that the third system information of the second class terminal device is updated within the second valid time occurs.

In some possible embodiments, after determining that a target system event of the M system events occurs, the terminal device may continue to execute a system task associated with the target system event. Here, the target system event includes one or more of the M system events.

The process of executing the system task associated with the target system event by the terminal device will be described in conjunction with the 4 specific system events described above.

For example, if it is determined that the network device does not send the SIB1 of the first type terminal device according to the indication information when a certain first type terminal device initially accesses the current cell, it may be determined that the first type terminal device cannot access the current cell. Further, the terminal device may perform cell reselection or resynchronization.

For another example, when a first type terminal device wakes up from a sleep state (i.e., Discontinuous Reception (DRX) state) or returns from outside the cell coverage to inside the coverage, the terminal device needs to re-synchronize with the network device. For the resynchronization procedure, similar to the initial access procedure, the terminal device needs to detect the PSS or SSS to complete time and frequency synchronization, then read the MIB information carried by the PBCH, and then read the SIB1 and other SI information. If the system information of the current cell is the same as the last valid system information acquired by the terminal, in principle, the terminal device may skip the process of reading SIB1 and other SI information, which is beneficial to reducing the time for acquiring the system information and reducing the power consumption of the terminal device. Therefore, when the terminal device determines that the network device has sent the SIB1 of the first type terminal device according to the indication information, and the first system information of the first type terminal device is updated, the first type terminal device needs to receive the updated first system information. If the first type of terminal device determines that the corresponding first system information is not updated according to the indication information, and the system information valid time of the first terminal device is not exceeded from the last time of receiving valid first system information to the current time, skipping a process of reading the first system information sent by the network device, otherwise, having to read the first system information, wherein the system information valid time of the first terminal device may be configured or predefined by the network device through signaling.

In the embodiment of the application, the network device forms the associated event group by the associated system events, then indicates whether each system event in the associated event group occurs or not by the indication identifiers in different identifier states, and indicates a plurality of system events by the indication identifiers less than the number of the system events, so that signaling overhead generated by the indication information is saved, and the utilization rate of communication resources is improved.
