In order to better understand the embodiments of the present disclosure, some exemplary embodiments are used to illustrate relevant application scenarios below:

In some embodiments, in some embodiments, 5G is introduced in response to people's pursuit of speed, latency, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life.

In some embodiments, the main application scenarios of 5G include: enhanced mobile ultra-wideband (eMBB, Enhanced Mobile Broadband), Ultra Reliable Low Latency Communication (URLLC, Ultra Reliable Low Latency Communication) and massive machine type communication (mMTC, Massive Machine Type Communication).

In some embodiments, eMBB still aims at users obtaining multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, in urban areas and in rural areas, its capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios.

In some embodiments, typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery) and traffic safety assurance, etc.

In some embodiments, typical features of mMTC include: high connection density, small data volume, latency-insensitive services, and module Low cost and long service life etc.

After the introduction of 5G technology, the energy consumption of 5G base stations is four times that of LTE base stations, so network energy saving is an important means for operators to reduce the cost of operating 5G systems.

In some embodiments, in order to save energy for terminals in a radio resource control (RRC) connected state, a power saving signal (WUS, Wake Up Signal) is introduced. An offset in front of the on duration of the discontinuous reception (C-DRX, Connected Discontinuous Reception) in the UE connected state defines a duration for sending a WUS signal. During the WUS duration, the WUS signal is sent, i.e., downlink control information (DCI, Downlink Control Information) 2-6, which is scrambled by the power saving signal-radio network temporary identifier (PS-RNTI, Power Saving-RNTI), and is used to indicate whether the terminal wakes up to monitor the physical downlink control channel (PDCCH, Physical Downlink Control Channel) during the next UE C-DRX on duration.

In some embodiments, in order to save energy for terminals in RRC idle or inactive states, a paging WUS is introduced. That is, a paging WUS is sent at a certain time before the paging occasion (PO), that is, a paging early indication (PEI), which is used to indicate whether the terminal monitors the paging scheduling information at the PO. The PEI is DCI 2-7, which is encrypted by PEI-RNTI.

In some embodiments, in order to reduce network energy consumption, the network energy saving topic is enabled. The four supported network energy saving (NES) functions include:

SSB-less Scell;

cell DTX/DRX;

Antenna port adaptation;

PDSCH transmission power adaptation.

In some embodiments, the synchronization signal block (SSB, SS and PBCH Block) includes the new air interface primary synchronization signal (NR-PSS, NR-Primary Synchronization Signal), the new air interface secondary synchronization signal (NR-SSS, NR-Secondary Synchronization Signal) or the air interface physical broadcast channel (NR-PBCH, NR-Physical Broadcast Channel) (PBCH DMRS, PBCH Demodulation Reference Signal), and its functions include:

Time-frequency synchronization (including fine synchronization or carrier frequency offset (CFO) estimation), corresponding to NR-PSS, NR-SSS or NR-PBCH DMRS;

Radio frame timing acquisition, corresponding to NR-PBCH (PBCH-DMRS);

Cell ID identification, corresponding to NR-PSS or NR-SSS;

Carrying main broadcast information, corresponding to NR-PBCH;

Radio Resource Management (RRM) measurement, corresponding to NR-SSS or NR-PBCH DMRS.

In some embodiments, the SSB is sent periodically and in a beam sweeping manner. See FIG. 1b , which is an SSB sent periodically for 20 ms.

In some embodiments, the configuration period of SSB can be configured in system information block 1 (SIB1, (SIB, System Information Block)).

In some embodiments, the SSB in the cell is sent according to a configured period, a fixed period, and according to the actual transmitted beam (SSB index) in a beam sweeping manner.

In some embodiments, for the periodic beam sweeping transmission of SSB, network power may be wasted in some scenarios. For example, in actual network deployment, some cells are capacity type cells and some cells are coverage type cells. For example: operators have deployed 3.5GHz NR consisting of macro cells and small cells. The macro cell provides a coverage layer, while the small cell provides a capacity layer that is activated when needed. As a result, the SSB period of the cell belonging to the unloaded capacity layer (denoted as a sleeping cell) is set to the maximum value, i.e., 160ms, while the coverage cell is configured with the default period, i.e., 20ms.

As shown in FIG2a, the present disclosure embodiment relates to an information indication method, which is used in a communication system 100, and the method includes:

Step S2101: The network device sends a first message to the terminal.

In some embodiments, the terminal receives a first message sent by the network device.

In some embodiments, the first message is a downlink control information (DCI, Downlink Control Information) message.

In some embodiments, the DCI is system information block 1 downlink control information SIB1-DCI.

In some embodiments, the first message is a MIB message.

It should be noted that, in the following examples, DCI messages, SIB1-DCI and MIB messages can be interchangeable in certain scenarios, and the following embodiments are only for illustrative purposes but are not limited thereto.

In some embodiments, the first message is used at least to indicate: a transmission period and/or a transmission timing for transmitting a synchronization signal block SSB.

In some embodiments, the first message is the DCI message, and the DCI message includes first information associated with a time window, and the first information is used to indicate the transmission period and/or the transmission timing for transmitting the SSB in the time window.

Exemplarily, the network defines a time window, and SIB1-DCI is used to indicate the transmission period and/or transmission timing (or transmission timing mode) of transmitting SSB starting from the boundary of the current or next time window.

Exemplarily, SIB1-DCI may include a bit, through which two periods may be configured. For example, when the value of the bit is "0" or "1", it indicates two different periods (for example, a first period and a second period) respectively.

In some embodiments, the DCI message includes a second information field; the second information field indicates, through a bitmap, whether to transmit or not transmit the SSB at transmission opportunities corresponding to different bits of the bitmap.

Exemplarily, the DCI message indicates the time when the SSB is transmitted and/or the time when the SSB is not transmitted. For example, whether the SSB is transmitted or not transmitted at the transmission time corresponding to different bits is indicated by a bitmap. For example, each bit corresponds to a transmission time, when the corresponding bit is set to "1", it indicates that the SSB is transmitted, and when the corresponding bit is set to "0", it indicates that the SSB is transmitted. The mode or bitmap corresponding to the transmission time may be pre-set in SIB1.

In some embodiments, the first message is sent within a first time period, and the transmission cycle and/or the transmission opportunity is used by the terminal within a second time period.

In some embodiments, the length of the first period and the second period can be m, where m = modification period.

Among them, modificationPeriodCoeff can be the modification period of the system broadcast change, or it can be the coefficient of the new configuration of the channel adaptation for the common signal, and defaultPagingCycle is the cell DRX cycle.

In some embodiments, the network device sends a first message in a modification period and starts applying the transmission period and/or the transmission opportunity at the next modification period boundary.

In some embodiments, the terminal determines the time window based on first predetermined protocol information.

Exemplarily, the time window can also be determined based on the first predetermined protocol information predefined by the system. For example, the time window includes n SSB cycles, and the starting position of the time window can be: system frame number (SFN, SFN) mod n×T=0, where T is the period for transmitting SSB.

In some embodiments, the terminal determines the time window based on configuration information included in SIB1.

Exemplarily, the time window may be configured in SIB1, for example, the cycle length and offset may be configured, in which case the starting position of the time window may be: SFN mod T = offset.

In some embodiments, the DCI is a DCI scrambled based on a predetermined radio network temporary identifier RNTI.

It should be noted that if the DCI includes a first DCI and a second DCI, the Radio Network Temporary Indentifier (RNTI) used to scramble the first DCI is different from the RNTI used to scramble the second DCI.

Exemplarily, the spare bit in the MIB is used to indicate the transmission period or transmission timing of the SSB. For example, when the spare bit takes the value of "0" and "1", it indicates that different periods are configured respectively.

In some embodiments, the second period is N times the first period, where N is an integer.

In some embodiments, the terminal determines the N based on second predetermined protocol information.

In some embodiments, the terminal determines the N based on the configuration information included in SIB1.

In some embodiments, the terminal determines N based on the period currently used for sending the SSB.

For example, please refer to Table 1, which shows the mapping relationship between the period of transmitting the SSB currently used and N.

Table 1

In some embodiments, the first message is a MIB message; the MIB message includes a second information field; the second information field indicates, through a bitmap, whether to transmit or not transmit the SSB at transmission times corresponding to different bits of the bitmap.

In some embodiments, the MIB message indicates the time when the SSB is transmitted and/or the time when the SSB is not transmitted. For example, whether the SSB is transmitted or not transmitted at the transmission time corresponding to different bits is indicated by a bitmap. For example, each bit corresponds to a transmission time, when the corresponding bit is set to "1", it indicates that the SSB is transmitted, and when the corresponding bit is set to "0", it indicates that the SSB is transmitted. The mode or bitmap corresponding to the transmission time may be pre-set in SIB1.

In some embodiments, the terminal receives SIB1 sent by the network device. Based on the configuration information included in SIB1, the terminal determines at least one of the first period and the second period.
