Furthermore, since eMBB may be deployed in different scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly. Therefore, it is not possible to generalize and requires detailed analysis based on specific deployment scenarios.

[0148] In some embodiments, typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance.

[0149] In some embodiments, typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low module cost and long service life.

[0150] 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.

[0151] In some embodiments, in order to save energy for terminals in a radio resource control (RRC) connected state, a power saving signal (WUS) is introduced. An offset in front of the on duration of the discontinuous reception (C-DRX) in the UE connected state defines a duration for sending the WUS signal. During this WUS duration, the WUS signal, i.e., downlink control information (DCI) 2-6, is sent and scrambled by the power saving signal-radio network temporary identifier (PS-RNTI) to indicate whether the terminal wakes up to monitor the physical downlink control channel (PDCCH) during the next UE C-DRX onduration.

[0152] In some embodiments, a paging WUS is introduced to save energy for terminals in RRC idle or inactive states. This WUS, also known as a Paging Early Indication (PEI), is sent sometime before a paging occasion (PO) to indicate whether the terminal is monitoring paging scheduling information at that PO. The PEI is DCI 2-7, scrambled using the PEI-RNTI.

[0153] In some embodiments, in order to reduce network energy consumption, a network energy saving project is launched. The four supported network energy saving (NES) functions include:

[0154] SSB-less Scell;

[0155] cell DTX / DRX;

[0156] Antenna port adaptation;

[0157] PDSCH transmission power adaptation.

[0158] 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:

[0159] Time-frequency synchronization (including fine synchronization or carrier frequency offset (CFO) estimation), corresponding to NR-PSS, NR-SSS or NR-PBCH DMRS;

[0160] Radio frame timing acquisition, corresponding to NR-PBCH (PBCH-DMRS);

[0161] Cell ID identification, corresponding to NR-PSS or NR-SSS;

[0162] Carrying main broadcast information, corresponding to NR-PBCH;

[0163] Radio Resource Management (RRM) measurement, corresponding to NR-SSS or NR-PBCH DMRS.

[0164] In some embodiments, the SSB is transmitted periodically and in a beam sweeping manner. See FIG1 b , which shows an SSB transmitted with a period of 20 ms.

[0165] In some embodiments, the configuration period of the SSB may be configured in the system information block 1 (SIB1, (SIB, System Information Block)).

[0166] In some embodiments, the SSBs in the cell are transmitted according to a configured period, a fixed period, and a beam sweeping method according to an actual transmitted beam (SSB index).

[0167] In some embodiments, the periodic beam sweeping mode of SSB transmission may waste network power 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. Macro cells provide a coverage layer, while small cells provide 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 a default period, i.e., 20ms.

[0168] FIG2a is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG2a, the embodiment of the present disclosure relates to an information indication method, which is used in a communication system 100 and includes:

[0169] Step S2101: The network device sends a first message to the terminal.

[0170] In some embodiments, the terminal receives a first message sent by the network device.

[0171] In some embodiments, the first message is a downlink control information (DCI) message.

[0172] In some embodiments, the DCI is system information block 1 downlink control information SIB1-DCI.

[0173] In some embodiments, the first message is a MIB message.

[0174] It should be noted that, in the following examples, DCI messages, SIB1-DCI and MIB messages can be interchangeable in certain scenarios. The following embodiments are only for illustrative purposes, but are not limited thereto.

[0175] In some embodiments, the first message is used to at least indicate: a transmission period and / or a transmission timing for transmitting a synchronization signal block SSB.

[0176] 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.

[0177] In some embodiments, the DCI message includes a first information field; the first information field carries a first value, and the DCI message is used to indicate that the transmission period for transmitting the SSB is a first period; the first information field carries a second value, and the DCI message is used to indicate that the transmission period for transmitting the SSB is a second period.

[0178] 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.

[0179] Exemplarily, SIB1-DCI may include one bit, through which two periods may be configured. For example, when the bit takes the value of "0" or "1", it indicates two different periods (for example, the first period and the second period) respectively.

[0180] 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.

[0181] 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 timing corresponding to different bits is indicated by a bitmap. For example, each bit corresponds to a transmission timing, and 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 timing may be pre-set in SIB1.

[0182] In some embodiments, the first message is sent within a first time period, and the transmission period and / or the transmission opportunity is used by the terminal within a second time period.

[0183] In some embodiments, the lengths of the first period and the second period may be m, where m=modification period.

[0184] For example, m=modificationPeriodCoeff*defaultPagingCycle;

[0185] Among them, modificationPeriodCoeff can be the modification period of the system broadcast change, or it can be the coefficient of the new channel adaptation configuration for the common signal, and defaultPagingCycle is the cell DRX cycle.

[0186] In some embodiments, the network device sends a first message during a modification period, and starts applying the transmission cycle and / or the transmission opportunity at a next modification period boundary.

[0187] In some embodiments, the terminal determines the time window based on first predetermined protocol information.

[0188] 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 periods, 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.

[0189] In some embodiments, the terminal determines the time window based on configuration information included in SIB1.

[0190] Exemplarily, the time window may be configured in SIB1, for example, the cycle length and offset may be configured, and the starting position of the time window may be: SFN mod T = offset.

[0191] In some embodiments, the DCI is a DCI scrambled based on a predetermined Radio Network Temporary Identifier (RNTI).

[0192] 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.

[0193] In some embodiments, the first message is a MIB message; the MIB message includes a first information field, the first information field carries a first value, and the MIB message is used to indicate that the transmission period for transmitting the SSB is a first period; the first information field carries a second value, and the MIB message is used to indicate that the transmission period for transmitting the SSB is a second period.

[0194] 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.

[0195] In some embodiments, the second period is N times the first period, where N is an integer.

[0196] In some embodiments, the terminal determines N based on second predetermined protocol information.

[0197] In some embodiments, the terminal determines N based on configuration information included in SIB1.

[0198] In some embodiments, the terminal determines N based on the currently used period for sending the SSB.

[0199] For example, please refer to Table 1, which shows the mapping relationship between the period of transmitting the SSB currently used and N.

[0200] Table 1

[0201] 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 the transmission timing corresponding to different bits of the bitmap.

[0202] 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, a bitmap is used to indicate whether the SSB is transmitted or not transmitted at the transmission opportunity corresponding to different bits. 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 pattern or bitmap corresponding to the transmission opportunity can be pre-set in SIB1.

[0203] In some embodiments, the terminal receives SIB1 sent by the network device. Based on configuration information included in SIB1, the terminal determines at least one of the first period and the second period.

[0204] Step S2102: The terminal and the network device perform SSB transmission (the terminal receives SSB, and the network device sends SSB).

[0205] In some embodiments, the network device sends the SSB to the terminal.

[0206] In some embodiments, the network device sends the SSB based on the transmission period and / or transmission opportunity indicated by the first message.

[0207] In some embodiments, the terminal receives the SSB sent by the network device based on the transmission period and / or transmission opportunity indicated by the first message.

[0208] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0209] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".
