Description

Communication method and communication device

Technical field

This application relates to the field of wireless communication, and in particular to a communication method and communication device.

Background technique

With the continuous development of wireless communication technology, in order to meet the increasing demand for communication services, the fifth-generation (5G) mobile communication technology (also known as the new radio (NR) technology) has been proposed . The services supported by 5G mobile communication technology are very diverse, such as enhanced mobile broadband (eMBB) services, ultra-reliability low-latency communication (URLLC) services, and so on. Recently, people have proposed a simplified NR system called the NR-light system. Compared with enhanced machine type communication (eMTC), the NR-light system has a higher data rate and reliability. In practical applications, the NR-light system can be nested with the enhanced mobile broadband system, so that it can provide suitable communication services for terminal devices with different business needs. Since the available time of the terminal device is an important factor that affects the user experience of the terminal device, how to reduce the power consumption of the terminal device is currently a major research hotspot.

In the prior art, the network device usually informs the terminal device of the result of whether some system events have occurred, so as to avoid the terminal device from performing some invalid operations, thereby reducing the power consumption of the terminal device. For example, the network device under the eMBB system will inform the terminal device in advance whether the system information sent by it has been updated, so that the terminal device does not need to repeatedly obtain the same system information from the network device when the system information is not updated. Reduce the power consumption of terminal equipment. However, since the network equipment in the existing method will respectively indicate various system events through corresponding indication information, as the number of system events that need to be indicated increases, the above indication information will generate a large amount of signaling overhead, which reduces the cost of communication resources.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application. It can be seen from Figure 1 that the communication system includes network equipment and user equipment. The network device can establish a connection with the terminal device through a wired connection, a wireless connection, or other connection methods. Of course, it can be understood that the communication system may include one or more network devices, and may include one or more terminal devices (such as terminal device 1 to terminal device 5 in FIG. 1). In the communication system shown in FIG. 1, the network device usually informs the terminal device of the result of whether some system events have occurred, so as to avoid the terminal device from 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 it is updated through the instruction information, so that the terminal device does not need to repeatedly obtain the same system information from the network device when the system information is not updated, thereby reducing the terminal device Power consumption. However, since the network equipment will respectively indicate various system events through corresponding indication information, as the number of system events that need to be indicated increases, the above indication information will generate a large amount of signaling overhead, which reduces the utilization of communication resources.

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

Example one

Please refer to FIG. 2, which is a schematic flowchart of a communication method provided by an embodiment of the present application. This communication method is suitable for the communication system shown in FIG. 1. In the embodiment of the present application, the network device needs to instruct the terminal device whether each system event of the M system events occurs. It can be seen from Figure 2 that the method includes the following steps:

S10. The network device determines the indication information.

In some feasible implementations, the network device can determine whether N system events in the first associated event group have occurred according to the current system status information, system logs, etc., and then determine the status of the N indicator tags contained in the indicator information . Here, the above-mentioned N indication identifiers are respectively used to indicate whether system events included in different associated event groups occur in different identification states. It can be understood that, in a certain specific identification state, the states of the aforementioned N indicator identifications can be used to indicate whether the system event included in the first associated event group has occurred. The foregoing first associated event group is composed of N associated system events out of M system events, and M is greater than N.

What needs to be explained here is that in the embodiment of the present application, the association between two system events refers to whether the first system event of the two system events occurs will determine whether it is necessary to indicate the occurrence of the second system event or Does not happen. N associated system events refer to the existence of at least two associated system events among these N system events, or at least one first system event among these N system events, and whether this first system event occurs It will be decided whether it is necessary to indicate the occurrence or non-occurrence of N-1 system events other than the first system event.

Optionally, in practical applications, before determining the identification status of the above-mentioned N indicator identifiers, the network device may first determine that at least one of the above-mentioned first associated event group is included according to whether the system events in the M system events are correlated. Or multiple associated event groups. 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 above-mentioned first associated event group, the network device can determine the N items included in the first associated time group according to current system status information, system logs, etc. Whether each system event in the associated system event occurs. If a certain system event occurs, the indicator flag corresponding to the system event among the above N indicator flags can be set to the first flag state (for ease of understanding and distinction, the first flag state is used in the following instead of description). If a certain system event does not occur, the indicator flag corresponding to the system event among the above N indicator flags can be set to the second flag state (for the convenience of distinction, the second flag state is used instead of description below). After the network device judges the N system events in the first associated event group N times, it can determine the identification status corresponding to each of the above N indicator identifications. It should be noted here that the above-mentioned first identification status and second identification status are only used to indicate that a certain identification has a different value or a different implementation form and does not have other limiting effects.

Optionally, in an optional implementation, the above-mentioned N indication identifiers may include a first indication identifier and a second indication identifier. The above M system events include the first system event, the second system event, and the third system event. Among them, the first system event is associated with the second system event, and the first system event is also associated with the third system event. Specifically, only when the first system event occurs, the second system event may occur. In the case where the first system event does not occur, the second system event will definitely not occur. In this way, the second system event does not need to indicate whether it has occurred, so the third system event can only be indicated if it has occurred. Therefore, the network device can group the first system event and the second system event into a first associated event group, and group the first system event and the third system event into a second associated event group. After determining the first event correlation group and the second time correlation group, the network device can determine whether the first system event occurs according to current system status information, system logs, and other information. If the network device determines that the above-mentioned first system event has occurred, the above-mentioned first indication flag can be set to the first flag state. Then, the network device can continue to determine whether the above-mentioned second system event occurs. If the network device determines that the second system event has occurred, it can set the second indication flag to the first flag state. If the network device determines that the second system event has not occurred, it can set the second indicator flag to The second identification state. If the network device determines that the above-mentioned first system event has not occurred, the above-mentioned first indication flag can be set to the second flag state. Then, the network device can continue to determine whether the aforementioned third system event occurs. If the network device determines that the third system event has occurred, the second indicator can be set to the first indicator state. If the network device determines that the third system event has not occurred, the second indicator can be set to The second identification state. That is, in the state where the first indicator is the first indicator, the first indicator and the second indicator are respectively used to indicate whether the first system event and the second system event occur. In the state of the first indicator being the second indicator, the first indicator and the second indicator are respectively used to indicate whether the first system event and the third system event in the second associated event group are occur. Finally, the network device may determine the first indication identifier and the second indication identifier of which the above-mentioned identifier status is known as the above-mentioned indication information.

Here, the different states of the two indicator marks are used to indicate whether three system events have occurred, which saves the signaling overhead generated by the indicator information and improves the utilization rate of communication resources.

It should be noted here that the first type of terminal equipment mentioned below in this application may be a massive machine-type communications (mMTC) terminal equipment, and the second type of terminal equipment may be other than mMTC terminals. The type of terminal equipment is not specifically limited in this application. Specifically, NR-light type terminal equipment may also be referred to as mMTC terminal equipment.

Optionally, in another specific implementation, the above-mentioned N indication identifiers may further include a third indication identifier for indicating whether the fourth system event occurs. The aforementioned first system event is not related to the aforementioned first system event, second system event, and third system event. Similarly, after determining the status of the first indicator and the second indicator, the network device can also determine whether the fourth system event has occurred according to system status information, system logs, and other information. If the network device determines that the fourth system event has occurred, it can set the third indication flag to the first flag state. If the network device determines that the fourth system event has not occurred, it can set the third indicator flag as the first flag. 2. Identification status.

Further, in the case of nesting of NR-light system and eMBB system. 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 above-mentioned first type of terminal equipment specifically refers to the terminal equipment under the NR-light system. The second system event is that the first system information of the first type of terminal device has been updated within the first valid time. The third system event is that the network device sends the first physical broadcast channel PBCH. Here, the above-mentioned first physical broadcast channel PBCH is used to carry the second system information of the first type of terminal equipment. The foregoing fourth system event may specifically be that the third system information of the second type of terminal device has been updated within the second valid time. Here, the above-mentioned second type of terminal device specifically refers to the terminal device under the eMBB system. It should be noted that both the first system information and the second system information refer to the system information corresponding to the first type of terminal device. The second system system information refers to the master information block (master information block, MIB) of the first type of terminal equipment carried in the first PBCH. This main information block contains necessary information related to cell camping, such as timing information, access information, system information block type 1 (system information block type 1, SIB1) configuration information, and so on. The foregoing first system information refers to system information other than the foregoing MIB corresponding to the terminal device. This first system information mainly includes SIB1 and other SIs other than SIB1. The other SIs mentioned above may include system information block type 2 (SIB2) and system information block type 3 (system information block type 3, SIB3) and many other system information blocks. The foregoing third system information is system information of the second type of terminal, specifically system information other than the MIB of the second type of terminal device, and may mainly include the SIB1 and other SIs of the second type of terminal device. The above-mentioned first PBCH is a physical broadcast channel introduced independently of the second PBCH. It is mainly used to carry additional system information for terminals of the first type, such as control resource set (CORESET) configuration information for scheduling the physical downlink control channel PDCCH of the terminal equipment SIB1 of the first type. The above-mentioned second PBCH is a traditional PBCH (that is, legacy PBCH), which is carried in a traditional synchronization signal and a PBCH block (SS/PBCH block, that is, legacy SSB). Here, the traditional SSB also carries a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). In practical applications, the time and frequency resources of a traditional SSB are shown in Table 1-1. Table 1-1 is a traditional SSB time and frequency resource table provided by an embodiment of the present application. This table mainly shows the positions of orthogonal frequency division multiplexing (OFDM) symbols of PSS, SSS, PBCH and other channels or signals relative to the start position of SSB, as well as PSS, SSS, PBCH and other channels or The subcarrier position of the signal relative to the SSB start position. Here,

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

It is the physical layer cell ID. The formula A mode B expresses that A performs modulo operation on B. In Table 1-1, PSS represents the time-frequency resource of PSS, and SSS represents the time-frequency resource of SSS. PBCH represents the time-frequency resource of the second PBCH. The PBCH demodulation reference signal (DMRS) (ie, DMRS for PBCH) indicates the DMRS used for the second PBCH. Set to 0 means protecting time-frequency resources. The protected time-frequency resource is not used to transmit information. In other words, Set to 0 indicates time-frequency resources that are not used to transmit information.

Table 1-1

In the following, combining the above four specific system events, the process of determining the indication information by the network device is briefly described. It is assumed here that the above-mentioned first indication identifier is indication bit A, the second indication identifier is indication bit B, and the third indication identifier is indication bit C.

In specific implementation, if the network device does not support NR-light or other types of NR mMTC system, it can indicate that the current cell does not support the access of the first type of terminal by indicating not to send SIB1 for the first type of terminal. After the class terminal reads this identifier, it will stop the access process in the current cell.

If the network device does not send the SIB1 corresponding to the first type of terminal device, it means that the first type of terminal device cannot access the network device, and there is no need to further indicate whether the first system information of the first type of terminal device is updated. . Therefore, the network device does not send the SIB1 system event corresponding to the terminal device of the first type and the first system information of the terminal device of the first type has been updated within the first valid time. The two system events are correlated. Here, if the network device does not send SIB1 corresponding to the first type of terminal device, it can be understood that the SSB currently sent by the network device does not include the control resource set (CORESET) 0, and the above CORESET0 includes the time domain resources occupied by the PDCCH. , Frequency domain resources and other information. In practical applications, a network device will send multiple SSBs. There may be several SSBs in the multiple SSBs that do not include CORESET0. This is because these SSBs are mainly used for radio resource measurement (RRM). In the case that the network device does not send the SIB1 corresponding to the first type of terminal device, the network device can also indicate to the first type of terminal device whether it has sent the first PBCH, so that the first type of terminal device determines that the network device has sent the first PBCH. When the first PBCH is used, the scheduling information of the SSB containing CORESET0 can be obtained from the first PBCH more quickly. Therefore, the system event that the network device sends the SIB1 corresponding to the first type of terminal device and the network device's transmission of the first physical broadcast channel PBCH are related to the system event. Therefore, the network device may send the SIB1 corresponding to the first type of terminal device and the first system information of the first type of terminal device sent by the network device and have been updated within the first valid time to form the first associated event group. In the same way, the network device may also form the second associated event group by the two events of the network device sending the SIB1 corresponding to the first type of terminal device and the network device sending the first PBCH.

Then, the network device can first determine whether it has sent the SIB1 of the first terminal device according to the system status information, system log, and other information. If the network device determines that it has sent the SIB1 of the first terminal device, it can set the value of the indication bit A to 1. Then, the network device can 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 type of terminal device is updated within the first valid time, the above indication bit B may be set to 1. If the network device determines that the first system information of the terminal device of the first type has not been updated within the first valid time, the above indication bit B may be set to 0. Then, the network device can 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 indicating bit C may be set to 1. If the network device determines that the third system information of the second type of terminal device has not been updated within the second valid time, the indicating bit C may be set to 0. That is to say, when the value of the indication bit A, the indication bit B, and the indication bit C contained in the above indication information is 100, it means that the above network device has sent the SIB1 of the first type of terminal device, and the first type of terminal device The first system information of the terminal device is not updated within the first valid time, and the third system information of the second-type terminal device is not updated within the second valid time. When the value of indicator bit A, indicator bit B, and indicator bit C is 111, it means that the above-mentioned network device has sent the SIB1 of the first type of terminal device, and the first system information of the first type of terminal device is valid in the first Update occurs within the time, and the third system information of the second type of terminal device is updated within the second valid time.

Or, if the network device determines that it has not sent the SIB1 of the first terminal device, the above indication bit A may be set to 0. Then, the network device can determine whether it sends the first PBCH. If the network device determines that it has sent the first PBCH, the above indication bit B can be set to 1. If the network device determines that it has not sent the first PBCH, the above indication bit B may be set to 0. Then, the network device can continue to determine whether the third system information of the second type of terminal device is updated within the second valid time.

For the resynchronization process, similar to the initial access process, the terminal device needs to first detect that the PSS or SSS completes 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 time the terminal obtained valid system information, in principle, the terminal device can skip the process of reading SIB1 and other SI information, which helps reduce the time for system information acquisition and reduces the power of the terminal device Consumption. Therefore, when the terminal device determines that the network device has sent the SIB1 of the first type of terminal device according to the above instruction information, and the first system information of the first type of terminal device is updated, the first type of terminal device needs to receive the updated first type of terminal device. One system information.

In the embodiment of the present application, the network device forms an associated event group by forming associated system events, and then indicates whether each system event in the associated event group has occurred through indications in different identification states, so as to be less than the number of system events. A number of indicators are used to indicate multiple system events, thereby saving the signaling overhead generated by the indicator information and improving the utilization rate of communication resources.
