Background

In a Long Term Evolution (LTE) communication system and a New Radio (NR) communication system, when system information is updated, a network device first sends a system information change instruction to a terminal device, where the system information change instruction is used to indicate that the system information is to be updated. After receiving the system information change instruction, the terminal device receives updated system information in the next system update period, for example, after receiving system information 1, receives system information 2 according to system information 1, and so on.

Specifically, as shown in fig. 1, the network device in the figure may send a change instruction (i.e., a system information change instruction) to the terminal device in the update period (n), that is, the terminal device receives the change instruction in the update period (n), but the system information at this time is still old system information. In the update period (n +1), the network device starts to issue new system information, that is, after the terminal device receives the system information 1, the terminal device receives the system information 2 in the corresponding system information window according to the content indicated by the system information 1. The content indicated by the system information 1 may include which system information is updated, the period size of the updated system information, the length of the window of the updated system information, and the like.

It can be understood that the embodiment of the present application is not limited to which message the network device sends the indication information.

402. The method comprises the steps that network equipment sends paging messages to terminal equipment, and the terminal equipment receives the paging messages sent by the network equipment; wherein the paging message carries at least one of system information and scheduling information of the system information.

Specifically, the indication information indicates that at least one of system information and scheduling information of the system information is carried through a paging message.

It is understood that the network device may also determine at least one of the system information and scheduling information of the system information prior to the network device transmitting the paging message to the terminal device.

Specifically, the network device may determine the system information according to whether the system information needs to be updated or whether the system information needs to be added or whether the system information is urgent. And the network equipment can also determine the scheduling information of the system information according to whether the scheduling information of the system information needs to be updated or whether the scheduling information of the system information needs to be increased. It is understood that the specific description of the system information and the scheduling information of the system information may refer to the related description of step 401, and is not detailed here.

Specifically, the paging message is carried in a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH);

and at least one of the system information and scheduling information of the system information is carried in the PDCCH and/or the PDSCH.

The paging message may be carried in the PDCCH, the PDSCH, or both the PDCCH and the PDSCH. That is, at least one of the system information and the scheduling information of the system information may be carried in the PDCCH, the PDSCH, or both the PDCCH and the PDSCH.

When a field in the DCI or the PDSCH of the paging message indicates a new system message or an update of the system message, the indication information may be a field of an existing DCI or PDSCH or may be a separate field. For example, one, a part, or all of the fields of the scheduling information in the DCI may be multiplexed, short message remaining bits or all or a part of the data bits in the DCI may be multiplexed, or a remaining bits field in the DCI may be multiplexed. When the terminal device receives the remaining value, it indicates that the system information is updated to the newly added system information or to the updated system information. It is also possible to indicate for a single value the system information to be added, for example the first value 0, or the last 1111, depending on the length of the field.

For example, the DCI of the paging message includes three types of information short message indications, short message information and scheduling information fields of PDSCH information. When the short message indication is 01, only the scheduling information of the PDSCH exists or only the scheduling information of the PDSCH is effective, when the short message indication is 10, only the short message information or only the short message information in the DCI exists or both the short message information and the scheduling information in the DCI are effective. The length of the short message is 8 bits of information, wherein only 2 bits are valid, and the remaining 6 bits of reserved data bit information.

A field in the DCI of the paging message may also be multiplexed to indicate scheduling information of the system message or the system message, for example, part or all data bits of a short message in the DCI of the multiplexed paging message and/or all or part of information in a field in the DCI of the multiplexed paging message that schedules the PDSCH transmits scheduling information of the system message or the system message. Or multiplexing part or all of the remaining data bits of the short message in the DCI of the paging message.

For example, when only a short message exists in the DCI or when only short message information is valid in the DCI, scheduling information or part or all of the scheduling information of the information transmission system message scheduling PDSCH resources and modulation schemes in the DCI may be multiplexed. An example of the partial field is a remaining data bit of the short message field indicating or transmitting scheduling information of system information. The scheduling information in the DCI may also be valid, for example, when only a short message exists in the DCI or when only short message information is valid in the DCI. For example, when the short message indication in the DCI in the NR indicates that the short message exists and the scheduling information does not exist, the scheduling information is valid. The scheduling information may be at least one or all of time-frequency domain resource location and modulation strategy of the PDSCH, resource mapping manner, transport block scaling factor (TB scaling), residual version, and other information. The other information may be all or part of data information of scheduling information of the system information, or all or part of the system information. When transmitting the scheduling information of the system message in the DCI, only the index or name of the updated system information may be transmitted. Only the index or name of one updated system information may be transmitted, or the indexes or names of all updated system information may be transmitted. For example, when only the short message exists in the DCI, the DCI may multiplex scheduling information of the information transmission system information of the PDSCH of the scheduling paging message, such as at least one of update information indicating the system information or indication information indicating new system information, a name and an index of the update system information, and scheduling information indicating the new system information. When only short messages exist in the DCI or when only short message information is effective in the DCI, and PDSCH information of scheduling paging messages in the multiplexed DCI is transmitted to update system information or add new system information, a plurality of items of updated system information scheduling information and the new system information can be indicated at the same time. It is also possible to indicate scheduling information of a plurality of items of updated system information at the same time. A field may be set to indicate using a bit-mapped approach. For example, MIB, SI1 and SI2, use 3 bits to indicate that the first bit represents MIB, the second bit represents SI1, and the third bit represents SI2, then 100 indicates that MIB is updated.

For example, when only the short message and the scheduling information coexist in the DCI, the scheduling information of the system message or the system message may be transmitted using the PDSCH of the paging message. Or transmitting the scheduling information of the system message using a part of data bits in a short message field in the DCI, where an example of the part of data bits is a remaining data bit indication of the short message field or the scheduling information of the transmission system information.

It can be understood that, in the case that the paging message is not required to carry the system information and the scheduling information of the system information, the network device may notify the terminal device of the indication information through the indication information, or the network device may not send the indication information, and the like.

It is understood that the information configured by the paging message received by the terminal device, as in LTE, may include two pieces of information, one piece of configuration information is a Discontinuous Reception (DRX) cycle T, which is 32 frames, 64 frames, 128 frames, 256 frames, respectively, and the other piece of configuration information is a number nB of paging access occasions (POs) within the DRX cycle, which is 4T,2T, T/2, T/4, T/8, T/16, T/32, respectively. According to the calculation method of the paging frame, for example, SFN mod T ═ T div N (UE _ ID mod N), the terminal device can know the frame where the paging message is located or in which frames the paging message is located. The paging subframe is calculated by i _ s ═ floor (UE _ ID/N) mod Ns, so that the terminal device can obtain the subframe in which the paging message is located. It is understood that the above is only an example shown in the embodiment of the present application, and in practical applications, the terminal device may also obtain the location where the paging message is located through other manners. Therefore, the embodiments of the present application do not limit the above method.

The terminal device may perform the operation of the terminal device in the method as shown in fig. 4, or the terminal device may also perform the operation of the terminal device shown in fig. 5.

For convenience of explanation, fig. 6 shows only main components of the terminal device. As shown in fig. 6, the terminal device 600 includes a processor, a memory, a radio frequency link, an antenna, and an input-output means. The processor is mainly used for processing the communication protocol and the communication data, controlling the whole terminal device, executing the software program, and processing the data of the software program, for example, for supporting the terminal device to execute the flow described in fig. 4. The memory is used primarily for storing software programs and data. The radio frequency link is mainly used for conversion of baseband signals and radio frequency signals and processing of the radio frequency signals. The antenna is mainly used for receiving and transmitting radio frequency signals in the form of electromagnetic waves. The terminal device 600 may further comprise input and output means, such as a touch screen, a display screen, a keyboard, etc., for mainly receiving data input by a user and outputting data to the user.

When the terminal device is powered on, the processor may read the software program in the storage unit (e.g., the memory), interpret and execute the software program, and process data of the software program. When data needs to be sent wirelessly, the processor outputs a baseband signal to the radio frequency link after performing baseband processing on the data to be sent, and the radio frequency link performs radio frequency processing on the baseband signal and sends the radio frequency signal outwards in the form of electromagnetic waves through the antenna. When data is transmitted to the terminal equipment, the radio frequency link receives radio frequency signals through the antenna, converts the radio frequency signals into baseband signals and outputs the baseband signals to the processor, and the processor converts the baseband signals into the data and processes the data.
