[0027] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0028] The information receiving method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0029] The terminals in various embodiments of this application support at least two communication modes, such as low-power (LP) mode and high-power (HP) mode. These communication modes can also be described as working modules, modules, modes, communication devices, transmission modes, transmit modes (Tx mode), receive modes, power classes, specifically associated reference signals, or specific corresponding resource sets. Activation or support of communication modes includes activation / deactivation of only one communication mode (e.g., high-power mode), or simultaneous activation / deactivation of at least two communication modes.

[0030] The aforementioned at least two communication modes can also refer to communication modes that differ significantly in one or more aspects such as frequency band / bandwidth / carrier, rate, transmission waveform, coverage level, sleep / discontinuous transmission (DTX) / discontinuous reception (DRX) time, paging cycle, synchronization signal and physical broadcast channel block (SSB) / system information block (SIB) cycle, whether resources are on demand, and SSB / SIB type. These can refer to different operating parameters used by the same communication hardware module, or to multiple different communication modules. Multiple communication modules can have at least one independent component at the physical layer, such as the RF front-end, antenna, or baseband; however, it is also possible for all components to be completely independent.

[0031] For at least two of the aforementioned communication modes, for example, one communication mode corresponds to a low-power, large-coverage scenario, while the other corresponds to a normal-coverage, high-power, high-speed application scenario. This allows for adaptive selection or switching of communication modes under different scenarios or network conditions, improving resource utilization and system performance. In this case, it is necessary to introduce rules for selecting relevant communication modes during initial cell search and network paging terminal processes, thereby using an appropriate communication mode to receive the first information and enhancing the flexibility of first information reception.

[0032] For at least two of the aforementioned communication modes, for example, integrating an ultra-low-power communication module on top of a traditional main communication module, the main communication module has high data rate and spectral efficiency, but also high power consumption. Prolonged operation will reduce the device's battery life, making it suitable for transmitting large amounts of data in a short time. Conversely, the ultra-low-power communication module may have lower data rate and spectral efficiency, but extremely low power consumption, making it suitable for transmitting small amounts of data over long periods, or for monitoring control plane signaling, avoiding or reducing additional latency caused by DRX. There is still no design to enable terminals with at least two communication modes to efficiently and reliably access the network, especially to utilize multiple communication modes to collaboratively transmit initial information related to cell search or paging, maximizing energy savings while ensuring performance.

[0033] The Band Width Part (BWP) switching in the various embodiments of this application can also be applied to the switching of at least one of carrier, TRP, band, subband, cell, waveform, power level, antenna, and antenna port.

[0034] The terminal in the various embodiments of this application can be any kind of communication terminal or device, and is not limited to a mobile phone terminal.

[0035] In the various embodiments of this application, the SSB can be replaced with a synchronization signal or a synchronization signal / broadcast channel, or it can be called any channel that includes a synchronization signal, a broadcast signal, a physical broadcast channel (PBCH), a downlink broadcast channel carrying system messages, or its control channel.

[0036] The SIB1 in the various embodiments of this application carries at least part of the cell information, and may also be other terms or multiple SIB types.

[0037] The paging message in the various embodiments of this application can be at least one of paging control information (such as a control channel that schedules the paging data channel), paging information (such as a paging data channel), a data channel scheduled by the paging control information (such as a PDSCH channel additionally scheduled by the paging DCI), or an additional data channel scheduled by the paging data channel (such as a PDSCH channel further scheduled by the paging PDSCH). The paging message content can be the paging message itself or a short message.

[0038] As shown in Figure 2, this application embodiment provides an information receiving method 200, which can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal, and the method includes the following steps.

[0039] S202: The terminal determines the target communication mode from at least two communication modes.

[0040] In this embodiment, the terminal supports at least two communication modes. The terminal can determine the target communication mode from all the communication modes it supports. The terminal can also determine a portion of the communication modes from all the communication modes it supports, and determine the target communication mode from these portion of the communication modes.

[0041] In this embodiment, the terminal can determine the target communication mode based on relevant information of the first information, and the target communication mode is used to receive the first information.

[0042] When a terminal determines the target communication mode, it can be understood as the target communication mode being activated. Activating the target communication mode means that the terminal can use the target communication mode to communicate.

[0043] S204: The terminal receives first information based on the target communication mode, the first information including at least one of the following: synchronization signal related information; paging related information; system message related information.

[0044] The synchronization signal related information includes, for example, a first synchronization signal and a second synchronization signal; wherein the first and second synchronization signals are contained in a synchronization signal block. In various embodiments of this application, the synchronization signal block can be a set of time-frequency resources carrying synchronization signals and / or system messages, and the synchronization signal block can be an SSB, etc. The first synchronization signal can be a first-level synchronization signal of the SSB, such as a primary synchronization signal (PSS); the second synchronization signal can be a second-level synchronization signal of the SSB, such as a secondary synchronization signal (SSS).

[0045] The paging-related information may include, for example, a paging data channel or a paging control channel for scheduling the paging data channel; wherein, the paging data channel may be a data channel carrying paging messages, such as Paging PDSCH; and the paging control channel may be a control channel for scheduling the data channel carrying paging messages, such as Paging PDCCH, wherein the Paging PDCCH is used to schedule the Paging PDSCH.

[0046] The system message related information includes, for example: a demodulation reference signal for a first broadcast channel, a first broadcast channel, a first system message data channel or a first system message control channel for scheduling the first system message data channel, a second system message data channel or a second system message control channel for scheduling the second system message data channel.

[0047] The first broadcast channel in various embodiments of this application is used to carry master system messages such as master information blocks (MIBs), and / or to carry information on receiving first system message control channels and / or first system message data channels. For example, the first broadcast channel may be called a physical broadcast channel (PBCH), and the demodulation reference signal of the first broadcast channel may be, for example, a PBCH demodulation reference signal (DMRS).

[0048] The first system message data channel can be a data channel carrying the first system message, such as a System Information Block (SIB). The first system message data channel can be an SIB PDSCH. The first system message control channel can be a control channel that schedules the data channel carrying the first system message, such as an SIB PDCCH, which is used to schedule the SIB PDSCH. The first system message refers to the necessary system message (such as common data and / or control channel configuration, common uplink and / or downlink carrier / frequency / BWP configuration, and at least one of cell bar related information) carried in addition to the first broadcast channel for the defined cell (or terminal access cell / network). It is also called SIB1 or Remaining Minimum System Information (RMSI).

[0049] The second system message data channel can be a data channel carrying second system messages, such as Other System Information (OSI). The second system message data channel can be an OSI PDSCH. The second system message control channel can be a control channel that schedules the data channel carrying the second system messages, such as an OSIPDCCH, which is used to schedule OSIPDSCH. OSI refers to other system messages that may differ from the first broadcast channel and the first system message.

[0050] The information receiving method provided in this application embodiment involves a terminal determining a target communication mode from at least two communication modes, and receiving first information based on the target communication mode. The first information includes at least one of the following: synchronization signal related information; paging related information; and system message related information. This application embodiment enables terminals supporting at least two communication modes to adopt appropriate target communication modes for different first information, improving the flexibility of first information reception and thus improving reception efficiency or reducing terminal power consumption.

[0051] In this application embodiment, the reception of first information can be optimized using relevant communication modes for different scenarios, maximizing system resource utilization efficiency. For example, in scenarios with low terminal speed and large coverage, or where low-power transmission is present, the terminal can select a low-power / low-performance target communication mode to receive the first information, which can significantly reduce terminal power consumption. For high-speed, high-reliability, high-power, and low-latency terminals, relevant communication modes and resources can also be selected to receive the first information, improving the reception efficiency and achieving rapid dwell, access, and paging, followed by entry into a high-speed, high-reliability communication mode.

[0052] In some embodiments, the synchronization signal-related information includes a first synchronization signal. The terminal can determine the target communication mode and receive the first synchronization signal based on the target communication mode. The first synchronization signal may be a first downlink reference signal that the terminal needs to receive for cell search, such as a PSS, or a second-level or second-type SSB.

[0053] In this embodiment, the terminal determines the target communication mode from at least two communication modes by: the terminal determining the target communication mode for receiving the first synchronization signal from at least two communication modes based on at least one of the following:

[0054] 1) Specific information about the synchronization signal block.

[0055] As mentioned earlier, the first synchronization signal may be part of the information of the synchronization signal block. Therefore, the terminal can determine the target communication mode based on the specific information of the synchronization signal block.

[0056] For example, specific information of a synchronization signal block is associated with at least one communication mode, and the terminal can determine the target communication mode for receiving the first synchronization signal based on the specific information of the synchronization signal block.

[0057] 2) Communication mode for receiving the first synchronization signal, indicated by the target cell, carrier, frequency band, or sub-band.

[0058] The target cell can be a cell other than the current cell, and the current cell can be the cell currently providing services to the terminal, such as the main cell; the carrier can be a carrier other than the current carrier, and the current carrier can be the carrier currently being used for terminal communication; the frequency band can be a frequency band other than the current frequency band, and the current frequency band can be the frequency band currently being used for terminal communication; the subband can be a subband other than the current subband, and the current subband can be the subband currently being used for terminal communication.

[0059] 3) The communication mode indicated by the target signaling, wherein the first synchronization signal belongs to the synchronization signal block of the non-cell defined (NCD) cell.

[0060] In this example, if the first synchronization signal belongs to the synchronization signal block of an undefined cell, the terminal can use the communication mode indicated by the target signaling as the communication mode for receiving the first synchronization signal.

[0061] The target signaling can be Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE) signaling, Downlink Control Information (DCI), etc. The RRC signaling includes, for example, Master Information Block (MIB), System Information Blocks (SIB), dedicated RRC signaling, common RRC signaling, etc.

[0062] 4) Default communication mode.

[0063] For example, the protocol pre-determines the target communication mode used to receive the first synchronization signal.

[0064] In this embodiment, the terminal can determine the target communication mode in the above manner and receive the first synchronization signal based on the target communication mode, thereby improving the flexibility of receiving the first synchronization signal, which is conducive to improving the receiving efficiency of the first synchronization signal or reducing the power consumption of the terminal.

[0065] In various embodiments of this application, the specific information of the synchronization signal block may include at least one of the following:

[0066] 1) Subcarrier Spacing (SCS) of the synchronization signal block.

[0067] 2) Transmission pattern of the synchronization signal block in the time-frequency domain.

[0068] 3) Type of synchronization signal block. For example, the synchronization signal block can be an SSB. The type of the synchronization signal block can include a level-one SSB, or a multi-level SSB, or which level of SSB the current SSB / PSS belongs to. The SSB can be a non-cell-defining SSB (NCD-SSB), or an SSB used only for measurement.

[0069] 4) The frequency band, frequency range (FR), or carrier where the synchronization signal block is located.

[0070] 5) Synchronization raster of synchronization signal block.

[0071] 6) The period of the synchronization signal block.

[0072] 7) The specific time unit where the synchronization signal block is located. For example, the synchronization signal block can be an SSB. In cases that support SSB hopping, within the time window for determining SSB transmission / activation, SSBs corresponding to different time units may use different communication modes.

[0073] 8) Synchronization signal block index or synchronization signal block group index. For example, a synchronization signal block index or synchronization signal block group index is mapped to a certain communication mode.

[0074] 9) The information carried by the synchronization signal block.

[0075] In some embodiments, the synchronization signal-related information includes a second synchronization signal. The terminal can determine the target communication mode and receive the second synchronization signal based on the target communication mode. The second synchronization signal may be a second downlink reference signal that the terminal needs to receive for cell search, such as an SSS, or a second-level or second-type SSB.

[0076] In this embodiment, the terminal determining the target communication mode from at least two communication modes includes: the terminal determining the target communication mode from at least two communication modes based on at least one of the following:

[0077] 1) Specific information about the synchronization signal block.

[0078] As mentioned earlier, the second synchronization signal can be part of the information in the synchronization signal block. Therefore, the terminal can determine the target communication mode based on the specific information in the synchronization signal block.

[0079] For example, specific information of a synchronization signal block is associated with at least one communication mode, and the terminal can determine the target communication mode for receiving the second synchronization signal based on the specific information of the synchronization signal block.

[0080] 2) Communication mode for receiving the second synchronization signal, indicated by the target cell, carrier, frequency band, or sub-band.

[0081] The target cell can be a cell other than the current cell; the carrier can be a carrier other than the current carrier; the frequency band can be a frequency band other than the current frequency band; the sub-band can be a sub-band other than the current sub-band.

[0082] 3) The communication mode indicated by the target signaling, wherein the second synchronization signal belongs to the synchronization signal block of the undefined cell.

[0083] In this example, if the second synchronization signal belongs to the synchronization signal block of an undefined cell, the terminal can use the communication mode indicated by the target signaling as the communication mode for receiving the second synchronization signal.

[0084] The target signaling can be RRC signaling, MAC CE signaling, DCI, etc. The RRC signaling includes, for example, the main MIB, SIB, dedicated RRC signaling, public RRC signaling, etc.

[0085] 4) Communication mode for receiving the first synchronization signal.

[0086] For example, the communication mode used to receive the first synchronization signal is the same; or the communication mode used to receive the first synchronization signal is mapped to the communication mode used to receive the second synchronization signal according to certain rules.

[0087] 5) Indication information of the first synchronization signal.

[0088] As mentioned above, the first synchronization signal and the second synchronization signal can be part of the information of the synchronization signal block. The terminal receives the first synchronization signal first. Therefore, the terminal can determine the communication mode to receive the second synchronization signal based on the indication information of the first synchronization signal.

[0089] For example, when the first synchronization signal is sequence 1, the second synchronization signal is received using communication mode 1; when the first synchronization signal is sequence 2, the second synchronization signal is received using communication mode 2; and so on.

[0090] For example, the ID indicated by the first synchronization signal (such as...) It is associated with a communication mode, and the ID is, for example, a function consisting of a cell ID and a communication mode ID.

[0091] 6) Measurements of the first synchronization signal. These measurements may include Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal-to-Interference-plus-Noise Ratio (SINR), and time delay.

[0092] For example, when the RSRP, RSRQ, or SINR of the first synchronization signal is greater than or less than a certain threshold, it is associated with a communication mode, which the terminal can use to receive the second synchronization signal (i.e., the target communication mode).

[0093] For example, when the delay in receiving the first synchronization signal (such as the number of synchronization signal block cycles experienced or the number of reception attempts) is greater than or less than a certain threshold, it is associated with a communication mode, and the terminal can use this communication mode (i.e., the target communication mode) to receive the second synchronization signal.

[0094] 7) Default communication mode.

[0095] For example, the protocol pre-determines the target communication mode used to receive the second synchronization signal.

[0096] In this embodiment, the terminal can determine the target communication mode in the above manner and receive the second synchronization signal based on the target communication mode, thereby improving the flexibility of receiving the second synchronization signal, which is conducive to improving the receiving efficiency of the second synchronization signal or reducing the power consumption of the terminal.

[0097] In some embodiments, the system message-related information includes a demodulation reference signal for a first broadcast channel. The terminal can determine a target communication mode and receive the demodulation reference signal for the first broadcast channel based on the target communication mode. The demodulation reference signal for the first broadcast channel may be a reference signal that the terminal needs to receive for cell search, or an X-level SSB, where X>1.

[0098] In this embodiment, the terminal determining the target communication mode from at least two communication modes includes: the terminal determining the target communication mode from at least two communication modes based on at least one of the following:

[0099] 1) Specific information about the synchronization signal block.

[0100] The demodulation reference signal of the first broadcast channel can be part of the information of the synchronization signal block. Therefore, the terminal can determine the target communication mode based on the specific information of the synchronization signal block.

[0101] For example, specific information of a synchronization signal block is associated with at least one communication mode, and the terminal can determine the target communication mode for receiving the demodulation reference signal of the first broadcast channel based on the specific information of the synchronization signal block.

[0102] 2) Communication mode for receiving demodulation reference signals of the first broadcast channel, indicated by the target cell, carrier, frequency band, or subband.

[0103] The target cell can be a cell other than the current cell; the carrier can be a carrier other than the current carrier; the frequency band can be a frequency band other than the current frequency band; the sub-band can be a sub-band other than the current sub-band.

[0104] 3) The communication mode indicated by the target signaling, wherein the demodulation reference signal of the first broadcast channel belongs to the synchronization signal block of the undefined cell.

[0105] In this example, if the demodulation reference signal of the first broadcast channel belongs to the synchronization signal block of an undefined cell, the terminal can use the communication mode indicated by the target signaling as the communication mode for receiving the demodulation reference signal of the first broadcast channel.

[0106] The target signaling can be RRC signaling, MAC CE signaling, DCI, etc. The RRC signaling includes, for example, the main MIB, SIB, dedicated RRC signaling, public RRC signaling, etc.

[0107] 4) Communication mode for receiving the first synchronization signal and / or the second synchronization signal.

[0108] For example, the communication mode used to receive the first synchronization signal and / or the second synchronization signal is the same; or the communication mode used to receive the first synchronization signal and / or the second synchronization signal is mapped to the communication mode used to receive the demodulation reference signal of the first broadcast channel according to certain rules.

[0109] 5) Indication information of the first synchronization signal and / or the second synchronization signal.

[0110] The first synchronization signal, the second synchronization signal, and the demodulation reference signal of the first broadcast channel can be partial information of the synchronization signal block. The terminal first receives the first synchronization signal and then receives the second synchronization signal. Therefore, the terminal can determine the communication mode used to receive the demodulation reference signal of the first broadcast channel based on the indication information of the first synchronization signal and / or the second synchronization signal.

[0111] For example, when the first synchronization signal and / or the second synchronization signal is sequence 1, the demodulation reference signal of the first broadcast channel is received using communication mode 1; when the first synchronization signal and / or the second synchronization signal is sequence 2, the demodulation reference signal of the first broadcast channel is received using communication mode 2; and so on.

[0112] For example, the ID or a combination of IDs indicated by the first synchronization signal and / or the second synchronization signal (e.g. or and The combination of the IDs is associated with a communication mode, such as a function consisting of a cell ID and a communication mode ID.

[0113] 6) Community signage.

[0114] The cell identifier can be the identifier of the currently accessing cell, or it can be the identifier of a neighboring cell, etc.

[0115] For example, the cell identifier corresponds to a certain communication mode. Therefore, the terminal can determine the target communication mode for receiving the demodulation reference signal of the first broadcast channel based on the cell identifier.

[0116] 7) Measurements of the first synchronization signal and / or the second synchronization signal. These measurements may include RSRP, RSRQ, SINR, or time delay, etc.

[0117] For example, when the RSRP, RSRQ, or SINR of the first or second synchronization signal is greater than or less than a certain threshold, it is associated with a communication mode, which the terminal can use to receive the demodulation reference signal of the first broadcast channel (i.e., the target communication mode).

[0118] For example, when the delay of receiving the first synchronization signal or the second synchronization signal (such as the number of synchronization signal block cycles experienced, the number of reception attempts) is greater than or less than a certain threshold, a communication mode is associated, and the terminal can use this communication mode (i.e. the target communication mode) to receive the demodulation reference signal of the first broadcast channel.

[0119] 8) Default communication mode.

[0120] For example, the protocol pre-determines the target communication mode used to receive the demodulation reference signal of the first broadcast channel.

[0121] In this embodiment, the terminal can determine the target communication mode in the above manner and receive the demodulation reference signal of the first broadcast channel based on the target communication mode, thereby improving the flexibility of receiving the demodulation reference signal of the first broadcast channel, which is conducive to improving the receiving efficiency of the demodulation reference signal of the first broadcast channel or reducing the power consumption of the terminal.

[0122] In some embodiments, the system message related information includes a first broadcast channel. The terminal can determine a target communication mode and receive the first broadcast channel based on the target communication mode. The first broadcast channel is used to carry master system messages such as MIB, and / or information on receiving the first system message control channel and / or the first system message data channel. For example, the first broadcast channel can be called a physical broadcast channel.

[0123] In this embodiment, the terminal determining the target communication mode from at least two communication modes includes: the terminal determining the target communication mode from at least two communication modes based on at least one of the following:

[0124] 1) Specific information about the synchronization signal block.

[0125] The first broadcast channel may contain partial information from the synchronization signal block; therefore, the terminal can determine the target communication mode based on specific information from the synchronization signal block.

[0126] For example, specific information of a synchronization signal block is associated with at least one communication mode, and the terminal can determine the target communication mode for receiving the first broadcast channel based on the specific information of the synchronization signal block.

[0127] 2) The communication mode for receiving the first broadcast channel, indicated by the target cell, carrier, frequency band, or subband.

[0128] The target cell can be a cell other than the current cell; the carrier can be a carrier other than the current carrier; the frequency band can be a frequency band other than the current frequency band; the sub-band can be a sub-band other than the current sub-band.

[0129] 3) The communication mode indicated by the target signaling, wherein the first broadcast channel belongs to the synchronization signal block of the undefined cell.

[0130] In this example, if the first broadcast channel belongs to the synchronization signal block of an undefined cell, the terminal can use the communication mode indicated by the target signaling as the communication mode for receiving the first broadcast channel.

[0131] The target signaling can be RRC signaling, MAC CE signaling, DCI, etc. The RRC signaling includes, for example, the main MIB, SIB, dedicated RRC signaling, public RRC signaling, etc.

[0132] 4) Communication mode for receiving the first synchronization signal, the second synchronization signal, or the demodulation reference signal of the first broadcast channel.

[0133] For example, the communication mode used to receive the first synchronization signal, the second synchronization signal, the second synchronization signal, or the demodulation reference signal of the first broadcast channel is the same; or according to certain rules, the communication mode used to receive the first synchronization signal, the second synchronization signal, the second synchronization signal, or the demodulation reference signal of the first broadcast channel is mapped to the communication mode used to receive the first broadcast channel.

[0134] 5) Indication information of the first synchronization signal and / or the second synchronization signal.

[0135] The first synchronization signal, the second synchronization signal, and the first broadcast channel may be part of the information of the synchronization signal block. The terminal receives the first synchronization signal first and then the second synchronization signal. Therefore, the terminal can determine the communication mode used to receive the first broadcast channel based on the indication information of the first synchronization signal and / or the second synchronization signal.

[0136] For example, when the first synchronization signal and / or the second synchronization signal is sequence 1, the first broadcast channel receives the signal using communication mode 1; when the first synchronization signal and / or the second synchronization signal is sequence 2, the first broadcast channel receives the signal using communication mode 2; and so on.

[0137] For example, the ID or a combination of IDs indicated by the first synchronization signal and / or the second synchronization signal (e.g. or and The combination of the IDs is associated with a communication mode, such as a function consisting of a cell ID and a communication mode ID.

[0138] 6) Indication information of the demodulation reference signal of the first broadcast channel.

[0139] For example, a specific sequence of the demodulation reference signal of the first broadcast channel or the generation parameters of the sequence (such as initial value, root sequence index, base sequence index, cyclic shift, sequence type, etc.) are associated with a communication mode, which the terminal can use to receive the first broadcast channel (i.e., the target communication mode).

[0140] For example, the location of the demodulation reference signal of the first broadcast channel, or the location group / code domain multiplexing (CDM) group, is associated with a communication mode that the terminal can use to receive the first broadcast channel (i.e., the target communication mode).

[0141] For example, the port of the demodulation reference signal of the first broadcast channel is associated with a communication mode that the terminal can use to receive the first broadcast channel (i.e., the target communication mode).

[0142] 7) Community signage.

[0143] The cell identifier can be the identifier of the currently accessing cell, or it can be the identifier of a neighboring cell, etc.

[0144] For example, the cell identifier corresponds to a certain communication mode. Therefore, the terminal can determine the target communication mode for receiving the first broadcast channel based on the cell identifier.

[0145] 8) Measurements of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel. These measurements may include RSRP, RSRQ, SINR, or time delay, etc.

[0146] For example, when the RSRP, RSRQ, or SINR of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel is greater than or less than a certain threshold, it is associated with a communication mode, and the terminal can use this communication mode (i.e., the target communication mode) to receive the first broadcast channel.

[0147] For example, when the delay (such as the number of synchronization signal block cycles experienced or the number of reception attempts) of receiving the first synchronization signal, the second synchronization signal, or the demodulation reference signal of the first broadcast channel is greater than or less than a certain threshold, a communication mode is associated, and the terminal can use this communication mode (i.e., the target communication mode) to receive the first broadcast channel.

[0148] 9) Default communication mode.

[0149] For example, the protocol pre-determines the target communication mode used to receive the first broadcast channel.

[0150] In this embodiment, the terminal can determine the target communication mode in the above manner and receive the first broadcast channel based on the target communication mode, thereby improving the flexibility of receiving the first broadcast channel, which is conducive to improving the receiving efficiency of the first broadcast channel or reducing the power consumption of the terminal.

[0151] In some embodiments, the system message related information includes a first system message data channel or a first system message control channel for scheduling the first system message data channel. The terminal can determine a target communication mode and receive the first system message data channel or the first system message control channel based on the target communication mode. The first system message refers to the necessary system message (such as at least one of the following: common data and / or control channel configuration, common uplink and / or downlink carrier / frequency / BWP configuration, and cell bar related information) carried in addition to the first broadcast channel for defining the cell (or terminal access cell / network). It is also called SIB1 or Residual Minimum System Information (RMSI). For example, the first system message can be an SIB, and the first system message data channel can be an SIB PDSCH. The SIB1 PDSCH refers to the system message transmitted on the data channel for carrying cell definition and connection information. The first system message control channel can be an SIB PDCCH, which is used to schedule the SIB PDSCH. In some scenarios, the SIB1 PDCCH can also refer to the control resource set (CORESET) or search space carrying the PDCCH.

[0152] In this embodiment, the terminal determining the target communication mode from at least two communication modes includes: the terminal determining the target communication mode from at least two communication modes based on at least one of the following:

[0153] 1) Specific information about the synchronization signal block.

[0154] The specific information of the synchronization signal block may include information carried by the synchronization signal block, the synchronization signal block index, or the synchronization signal block group index, etc. For details, please refer to the description of other embodiments.

[0155] For example, the information carried by the synchronization block directly indicates a communication mode, which the terminal can use to receive the first system message data channel or the first system message control channel. The information carried by the synchronization block includes at least one of the following: physical layer bits (L1 payload) in the payload of the first broadcast channel (such as PBCH); a specific field in the MIB; a spare bit; and fields jointly encoded with other information, such as those jointly encoded with service type, such as eMBB+ communication mode 1, eMBB+ communication mode 2, etc.

[0156] For example, a communication mode can be implicitly determined by the information carried by the synchronization block. The terminal can use this communication mode (i.e., the target communication mode) to receive the first system message data channel or the first system message control channel. The information carried by the synchronization block includes at least one of the following: System Frame Number (SFN); Subcarrier Spacing Common; SSB Subcarrier Offset; PDCCH Config SIB1; Cell Barred; Intra-Freq Reselection; Device / Service Type, such as eMBB, LPWA, etc.

[0157] For example, a synchronization signal block index or a synchronization signal block group index is mapped to a certain communication mode, and the terminal can use that communication mode (i.e., the target communication mode) to receive the first system message data channel or the first system message control channel.

[0158] 2) Communication mode indicated by target cell, carrier, frequency band or subband.

[0159] The target cell can be a cell other than the current cell; the carrier can be a carrier other than the current carrier; the frequency band can be a frequency band other than the current frequency band; the sub-band can be a sub-band other than the current sub-band.

[0160] 3) Communication mode indicated by target signaling.

[0161] The target signaling can be RRC signaling, MAC CE signaling, DCI, etc. The RRC signaling includes, for example, the main MIB, SIB, dedicated RRC signaling, public RRC signaling, etc.

[0162] 4) Receive synchronization signal block, first synchronization signal, second synchronization signal, demodulation reference signal of first broadcast channel or communication mode of first broadcast channel.

[0163] For example, the communication mode is the same as that used for receiving the synchronization signal block, the first synchronization signal, the second synchronization signal, the demodulation reference signal of the first broadcast channel, or the first broadcast channel; or, according to certain rules, the communication mode used for receiving the synchronization signal block, the first synchronization signal, the second synchronization signal, the demodulation reference signal of the first broadcast channel, or the first broadcast channel is mapped to the communication mode used for receiving the first system message data channel or the first system message control channel.

[0164] 5) Communication mode indicated by RRC release message.

[0165] The RRC release message can directly indicate the communication mode used to receive the first system message data channel or the first system message control channel.

[0166] 6) Indication information of the first synchronization signal or the second synchronization signal.

[0167] For example, when the first synchronization signal and / or the second synchronization signal is sequence 1, the first system message data channel or the first system message control channel is received using communication mode 1; when the first synchronization signal and / or the second synchronization signal is sequence 2, the first system message data channel or the first system message control channel is received using communication mode 2; and so on.

[0168] For example, the ID or a combination of IDs indicated by the first synchronization signal and / or the second synchronization signal (e.g. or and The combination of the IDs is associated with a communication mode, such as a function consisting of a cell ID and a communication mode ID.

[0169] 7) Indication information of the demodulation reference signal of the first broadcast channel.

[0170] For example, a specific sequence of the demodulation reference signal of the first broadcast channel or the generation parameters of the sequence (such as initial value, root sequence index, base sequence index, cyclic shift, sequence type, etc.) are associated with a communication mode, which the terminal can use to receive the first system message data channel or the first system message control channel.

[0171] For example, the location of the demodulation reference signal of the first broadcast channel, or the location group / CDM group, is associated with a communication mode that the terminal can use to receive the first system message data channel or the first system message control channel.

[0172] For example, the port of the demodulation reference signal of the first broadcast channel is associated with a communication mode that the terminal can use to receive the first system message data channel or the first system message control channel.

[0173] 8) Community signage.

[0174] The cell identifier can be the identifier of the currently accessing cell, or it can be the identifier of a neighboring cell, etc.

[0175] For example, the cell identifier corresponds to a certain communication mode. Therefore, the terminal can determine the target communication mode for receiving the first system message data channel or the first system message control channel based on the cell identifier.

[0176] 9) Measurements of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel. These measurements may include RSRP, RSRQ, SINR, or time delay, etc.

[0177] For example, when the RSRP, RSRQ, or SINR of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel is greater than or less than a certain threshold, it is associated with a communication mode, and the terminal can use this communication mode (i.e., the target communication mode) to receive the first system message data channel or the first system message control channel.

[0178] For example, when the delay (such as the number of synchronization signal block cycles experienced or the number of reception attempts) of receiving the first synchronization signal, the second synchronization signal, or the demodulation reference signal of the first broadcast channel is greater than or less than a certain threshold, a communication mode is associated, and the terminal can use this communication mode (i.e., the target communication mode) to receive the first system message data channel or the first system message control channel.

[0179] 10) Definition of the first control resource set or search space (e.g., CORESET#0, SearchspaceZero, or Searchspace#0).

[0180] For example, a table in the first control resource set or search space is bound to a certain communication mode. Different communication modes have different tables. Based on the above tables, the terminal can determine the target communication mode.

[0181] For example, at least one entry in the table of the first control resource set or search space defines the communication mode used by that entry, and the terminal can determine the target communication mode based on the above entry.

[0182] The first control resource set or search space refers to the time-frequency resource set that defines the control channel, including at least one of the following: the period in the time domain, the position in the period (or the offset of a fixed boundary, such as a slot or frame), the duration, the position in the frequency domain, the width of the frequency domain, or the number of frequency domain units (such as REs, RBs).

[0183] For example, the control channel may be a control channel for a data channel that schedules the first system message and / or the second system message.

[0184] 11) Definition of Time Domain Resource Assignment (TDRA) tables, lists, or indexes.

[0185] For example, the TDRA form is bound to a certain communication mode. Different communication modes have different forms. The terminal can determine the target communication mode based on the above forms.

[0186] For example, at least one entry in the TDRA table defines the communication mode used by that entry, and the terminal can determine the target communication mode based on the above entries.

[0187] 12) DCI instruction.

[0188] For example, the DCI is carried by the PDCCH. The Radio Network Temporary Identity (RNTI) scrambled by the PDCCH is associated with a communication mode. Based on the RNTI, the terminal can determine the target communication mode.

[0189] For example, a specific domain of DCI directly indicates the target communication mode.

[0190] For example, the DCI format of DCI is associated with a communication mode, and the terminal can determine the target communication mode based on this association.

[0191] In this embodiment, the terminal can determine the target communication mode in the above manner, and receive the first system message data channel or the first system message control channel based on the target communication mode, thereby improving the flexibility of receiving the first system message data channel or the first system message control channel, which is conducive to improving the receiving efficiency of the first system message data channel or the first system message control channel or reducing the terminal power consumption.

[0192] As a first sub-implementation of the previous embodiment, the method further includes: the terminal receiving configuration information, the configuration information including at least two first control resource sets or search spaces, the at least two first control resource sets or search spaces being used to receive the first system message control channel.

[0193] In this example, the network-side device configures at least two first control resource sets or search spaces for the terminal; the terminal uses at least two first control resource sets or search spaces to receive the first system message control channel, such as SIB1 PDCCH.

[0194] In one implementation, each of the first control resource sets or search spaces is associated with at least one communication mode. For example, one first control resource set or search space service is LPWA, corresponding to the terminal's LP or wide coverage communication mode; another first control resource set or search space service is eMBB, corresponding to the terminal's HP or normal coverage communication mode.

[0195] In another implementation, the target first system message data channel uses the communication mode associated with the target first control resource set or search space, and the target first system message data channel is scheduled by the control channel in the target first control resource set or search space. For example, the first system message data channel (such as SIB1 PDSCH) scheduled by the control channel in a specific first control resource set or search space uses a specific communication mode, that is, the communication mode of the scheduled first system message data channel depends on the communication mode associated with CORESET0 or SearchspaceZero.

[0196] It should be noted that the target's first system message data channel can be a specific first system message data channel; the target's first control resource set or search space can be a specific first control resource set or search space.

[0197] As a second sub-implementation of the previous embodiment, the first system message data channel is multiple, or the first system message data channel includes multiple transport blocks (TBs); wherein at least two different first system message data channels use the same communication mode; or at least two different TBs use the same communication mode.

[0198] For example, if the first system message data channel is SIB1 PDSCH, and multiple SIB1 PDSCHs or multiple TBs are supported, the communication mode can be determined as follows: different SIB1 PDSCHs or TBs use the same communication mode.

[0199] As a third sub-implementation of the previous embodiment, the first system message data channel is multiple, or the first system message data channel includes multiple TBs. The terminal determining the target communication mode from at least two communication modes further includes: the terminal determining the target communication mode from at least two communication modes based on the following information: the scheduling resource information of the first system message data channel or TB.

[0200] For example, the first system message data channel is SIB1 PDSCH. In the case of supporting multiple SIB1 PDSCHs or multiple TBs, the communication mode used by different SIB1 PDSCHs or TBs depends on the scheduling resource information of the SIB1 PDSCH or TB.

[0201] The scheduling resource information in various embodiments of this application may include at least one of the following:

[0202] 1) The size of time or frequency resources.

[0203] 2) Location of time or frequency resources.

[0204] 3) Whether duplicate transmissions occurred.

[0205] 4) Number of repeated transmissions.

[0206] 5) Modulation and Coding Scheme (MCS) or MCS index.

[0207] 6) Transport layer, transport layer index, or transport layer number.

[0208] 7) Transmission port, transmission port index, or set of transmission port indexes.

[0209] In some embodiments, the system message related information includes a second system message data channel or a second system message control channel for scheduling the second system message data channel. The terminal can determine a target communication mode and receive the second system message data channel or the second system message control channel based on the target communication mode. The second system message may be, for example, OSI, and the second system message data channel may be OSIPDSCH, which refers to system messages transmitted on a data channel; the second system message control channel may be OSIPDCCH, which is used to schedule OSI PDSCH. In some scenarios, OSIPDCCH may also refer to the control resource set (CORESET) or search space carrying the PDCCH.

[0210] In this embodiment, the terminal determining the target communication mode from at least two communication modes includes: the terminal determining the target communication mode from at least two communication modes based on at least one of the following:

[0211] 1) Specific information about the synchronization signal block.

[0212] 2) Communication mode indicated by target cell, carrier, frequency band or subband.

[0213] 3) Communication mode indicated by target signaling.

[0214] 4) Receive synchronization signal block, first synchronization signal, second synchronization signal, demodulation reference signal of first broadcast channel or communication mode of first broadcast channel.

[0215] 5) Communication mode indicated by RRC release message.

[0216] 6) Indication information of the first synchronization signal or the second synchronization signal.

[0217] 7) Indication information of the demodulation reference signal of the first broadcast channel.

[0218] 8) Community signage.

[0219] 9) Measurement of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel.

[0220] 10) Definition of the first control resource set or search space.

[0221] 11) Definition of TDRA forms or lists.

[0222] 12) DCI instruction.

[0223] Since the second system message (such as OSI) can reuse the scheduling mode of the first system message (such as SIB1), the method used to determine the target communication mode of the first system message data channel or the first system message control channel in the previous embodiment can also be used to determine the target communication mode of the second system message data channel or the second system message control channel. Therefore, the detailed descriptions of 1) to 12) above can be found in other embodiments.

[0224] 13) Communication mode indicated by the group common control channel.

[0225] For example, a specific value of a field of a group common control channel may be associated with a communication mode for receiving a second system message data channel or a second system message control channel; or a field may directly indicate the communication mode for receiving a second system message data channel or a second system message control channel.

[0226] 14) Communication mode indicated by the second system message control channel.

[0227] For example, the second system message control channel indicates a target communication mode for receiving the second system message data channel.

[0228] 15) Communication mode of the second system message control channel.

[0229] For example, the communication mode for receiving the second system message data channel is the same as the communication mode for receiving the second system message control channel; or, according to certain rules, the communication mode used for receiving the second system message control channel is mapped to the communication mode used for receiving the second system message data channel.

[0230] 16) A communication mode indicated by a paging data channel or a paging message carried by a paging data channel.

[0231] For example, the target communication mode for receiving the second system message data channel or the second system message control channel can be directly indicated by a specific field of the paging data channel or paging message.

[0232] For example, the target communication mode for receiving the second system message data channel or the second system message control channel can be indicated by an indication field of the paging data channel or the paging message joint encoding. This indication field may include, for example, a system information modification field, thereby indicating the target communication mode for receiving the second system message data channel or the second system message control channel.

[0233] 17) Communication mode indicated by paging control channel.

[0234] For example, a specific field of a paging control channel (such as Paging PDCCH) can be used to directly indicate the target communication mode for receiving a second system message data channel or a second system message control channel. This specific field can be the short message field of the paging control channel.

[0235] For example, the indication field jointly encoded by the paging control channel indicates the target communication mode for receiving the second system message data channel or the second system message control channel. This example could be achieved by jointly indicating the type of second system message to be received (e.g., OSI type) and the target communication mode for receiving the second system message data channel or the second system message control channel in the short message of the paging control channel.

[0236] For example, by using a specific field of the paging control channel, the target communication mode for receiving the second system message data channel or the second system message control channel can be implicitly determined. This example could be that the type of the second system message (such as OSI type) is indicated in the short message of the paging control channel, for instance, whether it is an Earthquake and Tsunami Warning System (ETWS) / Commercial Mobile Alert System (CMAS). If so, the terminal subsequently receives the second system message data channel or the second system message control channel using LP mode.

[0237] 18) Paging data channel or paging data channel communication mode.

[0238] For example, when the paging data channel or the paging data channel indicates that the terminal needs to receive a second system message, the communication mode of the corresponding second system message data channel or second system message control channel is the same as the communication mode of the paging data channel or paging data channel; or according to certain rules, the communication mode of the paging data channel or paging data channel is mapped to the communication mode of receiving the second system message data channel or second system message control channel.

[0239] 19) A paging data channel or a paging data channel resource, the paging data channel or paging data channel being used to indicate the second system message data channel or the second system message control channel.

[0240] The paging data channel or its resources may include at least one of the following: paging occasion index; paging frame index; paging occasion (PO); paging data channel or the time-domain window location of the paging data channel; paging cycle; discontinuous reception (DRX) or discontinuous transmission (DTX) cycle; system information change period; SSB index associated with PO resources; mapping cycle of SSB and PO; mapping method of SSB and PO (e.g., time-domain / frequency-domain priority).

[0241] 20) Communication mode indicated by Wake Up Signaling (WUS).

[0242] For example, triggering the WUS signal of SSB or SIB1, or OSI or PRACH can indicate the communication mode for receiving the second system message data channel or the second system message control channel.

[0243] In this embodiment, the terminal can determine the target communication mode in the above manner, and receive the second system message data channel or the second system message control channel based on the target communication mode, thereby improving the flexibility of receiving the second system message data channel or the second system message control channel, which is conducive to improving the receiving efficiency of the second system message data channel or the second system message control channel or reducing the terminal power consumption.

[0244] As a first sub-implementation of the above embodiments, the multiple provisions of the above embodiments involving "indicated communication modes", such as the communication mode indicated by the second system message control channel in 14) above; or the communication mode indicated by the paging data channel or the paging message carried by the paging data channel in 16) above; or the communication mode indicated by the paging control channel in 17) above, etc., may include at least one of the following:

[0245] 1) The communication mode used to receive the second system message control channel or the second system message data channel in X time units (e.g., SIMODIC Period), where X is a positive integer.

[0246] 2) Time-domain pattern, the time-domain pattern is used to determine the communication mode of the second system message control channel or the second system message data channel. For example, communication mode 1 is used for the first X time units within a period of time, and communication mode 2 is used for the last Y time units.

[0247] 3) Use different communication modes to receive different types of the second system message control channel or the second system message data channel.

[0248] 4) Using the same communication mode, receive different types of the second system message control channel or the second system message data channel;

[0249] 5) The synchronization signal block index or synchronization signal block group index associated with the second system message control channel or the second system message data channel; wherein the synchronization signal block index or synchronization signal block group index is used to determine the communication mode of the second system message control channel or the second system message data channel.

[0250] For example, when the CORESET of the second system message control channel is associated with SSB X, communication mode X is used to receive the second system message control channel or the second system message data channel.

[0251] The mapping relationship between the above-mentioned synchronization signal block index or synchronization signal block group index and communication mode can be the default or indicated by the network-side device.

[0252] As a second sub-implementation of the previous embodiment, the second system message data channel is multiple, or the second system message data channel includes multiple TBs; wherein at least two different second system message data channels use the same communication mode; or at least two different TBs use the same communication mode.

[0253] For example, the second system message data channel is OSIPDSCH. In the case of supporting multiple OSIPDSCH or multiple TB, the communication mode can be determined as follows: different OSIPDSCH or TB use the same communication mode.

[0254] As a third sub-implementation of the previous embodiment, the second system message data channel is multiple, or the second system message data channel includes multiple TBs. The terminal determining the target communication mode from at least two communication modes further includes: the terminal determining the target communication mode from at least two communication modes based on the following information: the scheduling resource information of the second system message data channel or TB.

[0255] For example, the second system message data channel is OSIPDSCH. In the case of supporting multiple OSIPDSCH or multiple TB, the communication mode used by different OSIPDSCH or TB depends on the scheduling resource information of OSIPDSCH or TB.

[0256] The scheduling resource information in various embodiments of this application may include at least one of the following:

[0257] 1) The size of time or frequency resources.

[0258] 2) Location of time or frequency resources.

[0259] 3) Whether duplicate transmissions occurred.

[0263] 7) Transmission port, transmission port index, or set of transmission port indexes.

[0264] In some embodiments, the paging-related information includes a paging data channel, a paging control channel for scheduling the paging data channel, or a paging channel. The terminal can determine a target communication mode and receive the paging data channel, paging control channel, or paging channel based on the target communication mode. The paging data channel can be a Paging PDSCH, which refers to paging transmitted on the data channel; the paging control channel can be a Paging PDCCH, which can be used to schedule the Paging PDSCH. In some scenarios, the Paging PDCCH can also refer to the control resource set (CORESET) or search space carrying the PDCCH.

[0265] In this embodiment, the terminal determining the target communication mode from at least two communication modes includes: the terminal determining the target communication mode from at least two communication modes based on at least one of the following:

[0266] 1) Specific information about the synchronization signal block.

[0267] 2) Communication mode indicated by target cell, carrier, frequency band or subband.

[0268] 3) The communication mode indicated by the target signaling, wherein the paging data channel, the paging control channel, or the paging channel belongs to an undefined cell.

[0269] 4) Receive synchronization signal block, first synchronization signal, second synchronization signal, demodulation reference signal of first broadcast channel or communication mode of first broadcast channel.

[0270] 5) Communication mode indicated by RRC release message.

[0271] 6) Indication information of the first synchronization signal or the second synchronization signal.

[0272] 7) Indication information of the demodulation reference signal of the first broadcast channel.

[0273] 8) Community signage.

[0274] 9) Measurement of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel.

[0275] 10) Definition of the first control resource set or search space.

[0276] 11) Definition of TDRA forms or lists.

[0277] 12) DCI instruction.

[0278] Since paging messages can reuse the scheduling mode of first system messages (such as SIB1), the method for determining the target communication mode of the first system message data channel or the first system message control channel can also be used to determine the target communication mode of the paging data channel, the paging control channel, or the paging channel. Therefore, the detailed descriptions of 1) to 12) above can be found in other embodiments.

[0279] 13) Communication mode indicated by the group common control channel.

[0280] For example, a specific value of a field of a group common control channel may be associated with a communication mode for receiving paging data channels, paging control channels, or paging channels; or a field may directly indicate the communication mode for receiving paging data channels, paging control channels, or paging channels.

[0281] The aforementioned group common PDCCH can be, for example, a paging advance indication (PEI), DCI2_7. The fields that can be used for indication include, but are not limited to: paging advance indication search space, paging advance indication frame offset, first PDCCH monitoring Occasion of PEI-O, number of subgroups at paging time (subgroupsNumberPO), and number of paging advance indications at paging time (po-NumberPEI).

[0282] 14) Communication mode indicated by paging control channel.

[0283] For example, the paging control channel indicates a target communication mode for receiving paging data channels or paging channels.

[0284] For example, a specific field of the paging control channel can be used to directly indicate the target communication mode for receiving paging data channels or paging channels. This specific field can be a short message field.

[0285] For example, the indicator field of the paging control channel, which is jointly encoded, indicates the target communication mode for receiving the paging data channel. For instance, in the short message indicator of the paging control channel, the paging type to be received and the target communication mode for receiving the paging data channel are jointly indicated. For example, 01 corresponds to receiving only the paging data channel, which corresponds to the LP mode; 11 corresponds to receiving both the paging data channel and the short message, which corresponds to the HP mode.

[0286] For example, a specific field in the paging control channel implicitly determines the target communication mode for receiving the paging data channel or the paging channel. This example could be indicated in the short message of the paging control channel, specifying whether it is eMBB; if so, the terminal subsequently receives the paging data channel or the paging channel in HP mode.

[0287] 15) Communication mode of paging control channel.

[0288] For example, the communication mode of receiving the paging data channel or the paging channel is the same as the communication mode of receiving the paging control channel; or according to certain rules, the communication mode used to receive the paging control channel is mapped to the communication mode used to receive the paging data channel or the paging channel.

[0289] 16) Resources for receiving paging messages.

[0290] The resource for receiving paging messages may include at least one of the following: paging occasion index; paging frame index; paging occasion (PO), paging data channel, or the time-domain window position of the paging data channel; paging cycle; discontinuous reception (DRX) or discontinuous transmission (DTX) cycle; system information modification period; SSB index associated with the PO resource; mapping cycle between SSB and PO; mapping method between SSB and PO (e.g., time-domain / frequency-domain priority).

[0291] 17) Communication mode indicated by WUS.

[0292] For example, triggering the WUS signal of SSB or SIB1, or OSI or PRACH can indicate the communication mode for receiving paging data channels, paging control channels or paging channels.

[0293] In this embodiment, the terminal can determine the target communication mode in the above manner, and receive the paging data channel, paging control channel or paging channel based on the target communication mode, thereby improving the flexibility of receiving the paging data channel, paging control channel or paging channel, which is conducive to improving the receiving efficiency of the paging data channel, paging control channel or paging channel or to reducing the terminal power consumption.

[0294] As a first sub-implementation of the above embodiments, the multiple provisions of the above embodiments involving "indicated communication modes", such as the communication mode indicated by the group common control channel in 13) above; or the communication mode indicated by the paging control channel in 14) above, may include at least one of the following:

[0296] 2) Time-domain pattern, which is used to determine the communication mode of the paging control channel, the paging data channel or the paging channel. For example, communication mode 1 is used for the first X time units within a period of time, and communication mode 2 is used for the last Y time units.

[0297] 3) Using different communication modes, receive different types of the paging control channel, the paging data channel, or the paging channel.

[0314] In various embodiments of this application, if the terminal's current communication mode differs from or is reselected from the intended communication mode, the switching or selection time needs to be considered, or a minimum time interval needs to be defined. The terminal may not expect the network to indicate a communication mode switch that does not meet the time requirements, or the terminal may decide whether to actually switch for a switch that does not meet the time requirements, such as not switching if the switch does not meet the requirements, thereby ensuring the reliability and feasibility of communication mode switching or reselection.

[0369] 5) Indication information of the first synchronization signal.

[0370] As mentioned above, the first synchronization signal and the second synchronization signal can be part of the information of the synchronization signal block.

[0422] For example, the cell identifier corresponds to a certain communication mode. Therefore, the terminal can determine the target communication mode for receiving the first broadcast channel based on the cell identifier.

[0423] 8) Measurements of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel. These measurements may include RSRP, RSRQ, SINR, or time delay, etc.

[0424] For example, when the RSRP, RSRQ, or SINR of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel is greater than or less than a certain threshold, it is associated with a communication mode, and the terminal can use this communication mode (i.e., the target communication mode) to receive the first broadcast channel.

[0425] For example, when the delay (such as the number of synchronization signal block cycles experienced or the number of reception attempts) of receiving the first synchronization signal, the second synchronization signal, or the demodulation reference signal of the first broadcast channel is greater than or less than a certain threshold, a communication mode is associated, and the terminal can use this communication mode (i.e., the target communication mode) to receive the first broadcast channel.

[0426] 9) Default communication mode.

[0427] For example, the protocol pre-determines the target communication mode used to receive the first broadcast channel.

[0428] In this embodiment, the terminal can determine the target communication mode in the above manner and receive the first broadcast channel based on the target communication mode, thereby improving the flexibility of receiving the first broadcast channel, which is conducive to improving the receiving efficiency of the first broadcast channel or reducing the power consumption of the terminal.

[0429] In some embodiments, the system message related information includes a first system message data channel or a first system message control channel for scheduling the first system message data channel, and the processing module 302 is configured to determine a target communication mode from at least two communication modes based on at least one of the following:

[0430] 1) Specific information about the synchronization signal block.

[0431] The specific information of the synchronization signal block may include information carried by the synchronization signal block, the synchronization signal block index, or the synchronization signal block group index, etc. For details, please refer to the description of other embodiments.

[0432] For example, the information carried by the synchronization block directly indicates a communication mode, which the terminal can use to receive the first system message data channel or the first system message control channel. The information carried by the synchronization block includes at least one of the following: physical layer bits (L1 payload) in the payload of the first broadcast channel (such as PBCH); a specific field in the MIB; a spare bit; and fields jointly encoded with other information, such as those jointly encoded with service type, such as eMBB+ communication mode 1, eMBB+ communication mode 2, etc.

[0433] For example, a communication mode can be implicitly determined by the information carried by the synchronization block. The terminal can use this communication mode (i.e., the target communication mode) to receive the first system message data channel or the first system message control channel. The information carried by the synchronization block includes at least one of the following: System Frame Number (SFN); Subcarrier Spacing Common; SSB Subcarrier Offset; PDCCH Config SIB1; Cell Barred; Intra-Freq Reselection; Device / Service Type, such as eMBB, LPWA, etc.

[0434] For example, a synchronization signal block index or a synchronization signal block group index is mapped to a certain communication mode, and the terminal can use that communication mode (i.e., the target communication mode) to receive the first system message data channel or the first system message control channel.

[0435] 2) Communication mode indicated by target cell, carrier, frequency band or subband.

[0436] The target cell can be a cell other than the current cell; the carrier can be a carrier other than the current carrier; the frequency band can be a frequency band other than the current frequency band; the sub-band can be a sub-band other than the current sub-band.

[0437] 3) Communication mode indicated by target signaling.

[0438] The target signaling can be RRC signaling, MAC CE signaling, DCI, etc. The RRC signaling includes, for example, the main MIB, SIB, dedicated RRC signaling, public RRC signaling, etc.

[0439] 4) Receive synchronization signal block, first synchronization signal, second synchronization signal, demodulation reference signal of first broadcast channel or communication mode of first broadcast channel.

[0440] For example, the communication mode is the same as that used for receiving the synchronization signal block, the first synchronization signal, the second synchronization signal, the demodulation reference signal of the first broadcast channel, or the first broadcast channel; or, according to certain rules, the communication mode used for receiving the synchronization signal block, the first synchronization signal, the second synchronization signal, the demodulation reference signal of the first broadcast channel, or the first broadcast channel is mapped to the communication mode used for receiving the first system message data channel or the first system message control channel.

[0441] 5) Communication mode indicated by RRC release message.

[0442] The RRC release message can directly indicate the communication mode used to receive the first system message data channel or the first system message control channel.

[0443] 6) Indication information of the first synchronization signal or the second synchronization signal.

[0444] For example, when the first synchronization signal and / or the second synchronization signal is sequence 1, the first system message data channel or the first system message control channel is received using communication mode 1; when the first synchronization signal and / or the second synchronization signal is sequence 2, the first system message data channel or the first system message control channel is received using communication mode 2; and so on.

[0445] For example, the ID or a combination of IDs indicated by the first synchronization signal and / or the second synchronization signal (e.g. or and The combination of the IDs is associated with a communication mode, such as a function consisting of a cell ID and a communication mode ID.

[0446] 7) Indication information of the demodulation reference signal of the first broadcast channel.

[0447] For example, a specific sequence of the demodulation reference signal of the first broadcast channel or the generation parameters of the sequence (such as initial value, root sequence index, base sequence index, cyclic shift, sequence type, etc.) are associated with a communication mode, which the terminal can use to receive the first system message data channel or the first system message control channel.

[0448] For example, the location of the demodulation reference signal of the first broadcast channel, or the location group / CDM group, is associated with a communication mode that the terminal can use to receive the first system message data channel or the first system message control channel.

[0449] For example, the port of the demodulation reference signal of the first broadcast channel is associated with a communication mode that the terminal can use to receive the first system message data channel or the first system message control channel.

[0450] 8) Community signage.

[0451] The cell identifier can be the identifier of the currently accessing cell, or it can be the identifier of a neighboring cell, etc.

[0452] For example, the cell identifier corresponds to a certain communication mode. Therefore, the terminal can determine the target communication mode for receiving the first system message data channel or the first system message control channel based on the cell identifier.

[0453] 9) Measurements of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel. These measurements may include RSRP, RSRQ, SINR, or time delay, etc.

[0454] For example, when the RSRP, RSRQ, or SINR of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel is greater than or less than a certain threshold, it is associated with a communication mode, and the terminal can use this communication mode (i.e., the target communication mode) to receive the first system message data channel or the first system message control channel.

[0455] For example, when the delay (such as the number of synchronization signal block cycles experienced or the number of reception attempts) of receiving the first synchronization signal, the second synchronization signal, or the demodulation reference signal of the first broadcast channel is greater than or less than a certain threshold, a communication mode is associated, and the terminal can use this communication mode (i.e., the target communication mode) to receive the first system message data channel or the first system message control channel.

[0456] 10) Definition of the first control resource set or search space (e.g., CORESET0 or SearchspaceZero).

[0457] For example, a table in the first control resource set or search space is bound to a certain communication mode. Different communication modes have different tables. Based on the above tables, the terminal can determine the target communication mode.

[0458] For example, at least one entry in the table of the first control resource set or search space defines the communication mode used by that entry, and the terminal can determine the target communication mode based on the above entry.

[0459] 11) Definition of Time Domain Resource Assignment (TDRA) tables, lists, or indexes.

[0460] For example, the TDRA form is bound to a certain communication mode. Different communication modes have different forms. The terminal can determine the target communication mode based on the above forms.

[0461] For example, at least one entry in the TDRA table defines the communication mode used by that entry, and the terminal can determine the target communication mode based on the above entries.

[0462] 12) DCI instruction.

[0463] For example, the DCI is carried by the PDCCH. The Radio Network Temporary Identity (RNTI) scrambled by the PDCCH is associated with a communication mode. Based on the RNTI, the terminal can determine the target communication mode.

[0464] For example, a specific domain of DCI directly indicates the target communication mode.

[0465] For example, the DCI format of DCI is associated with a communication mode, and the terminal can determine the target communication mode based on this association.

[0466] In this embodiment, the terminal can determine the target communication mode in the above manner, and receive the first system message data channel or the first system message control channel based on the target communication mode, thereby improving the flexibility of receiving the first system message data channel or the first system message control channel, which is conducive to improving the receiving efficiency of the first system message data channel or the first system message control channel or reducing the terminal power consumption.

[0467] In some embodiments, the system message related information includes a second system message data channel or a second system message control channel for scheduling the second system message data channel, and the processing module 302 is configured to determine a target communication mode from at least two communication modes based on at least one of the following:

[0468] 1) Specific information about the synchronization signal block.

[0469] 2) Communication mode indicated by target cell, carrier, frequency band or subband.

[0470] 3) Communication mode indicated by target signaling.

[0471] 4) Receive synchronization signal block, first synchronization signal, second synchronization signal, demodulation reference signal of first broadcast channel or communication mode of first broadcast channel.

[0472] 5) Communication mode indicated by RRC release message.

[0473] 6) Indication information of the first synchronization signal or the second synchronization signal.

[0474] 7) Indication information of the demodulation reference signal of the first broadcast channel.

[0475] 8) Community signage.

[0476] 9) Measurement of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel.

[0477] 10) Definition of the first control resource set or search space.

[0478] 11) Definition of TDRA forms or lists.

[0479] 12) DCI instruction.

[0480] Since the second system message (such as OSI) can reuse the scheduling mode of the first system message (such as SIB1), the method used to determine the target communication mode of the first system message data channel or the first system message control channel in the previous embodiment can also be used to determine the target communication mode of the second system message data channel or the second system message control channel. Therefore, the detailed descriptions of 1) to 12) above can be found in other embodiments.

[0481] 13) Communication mode indicated by the group common control channel.

[0482] For example, a specific value of a field of a group common control channel may be associated with a communication mode for receiving a second system message data channel or a second system message control channel; or a field may directly indicate the communication mode for receiving a second system message data channel or a second system message control channel.

[0483] 14) Communication mode indicated by the second system message control channel.

[0484] For example, the second system message control channel indicates a target communication mode for receiving the second system message data channel.

[0485] 15) Communication mode of the second system message control channel.

[0486] For example, the communication mode for receiving the second system message data channel is the same as the communication mode for receiving the second system message control channel; or, according to certain rules, the communication mode used for receiving the second system message control channel is mapped to the communication mode used for receiving the second system message data channel.

[0487] 16) A communication mode indicated by a paging data channel or a paging message carried by a paging data channel.

[0488] For example, the target communication mode for receiving the second system message data channel or the second system message control channel can be directly indicated by a specific field of the paging data channel or paging message.

[0489] For example, the target communication mode for receiving the second system message data channel or the second system message control channel can be indicated by an indication field of the paging data channel or the paging message joint encoding. This indication field may include, for example, a system information modification field, thereby indicating the target communication mode for receiving the second system message data channel or the second system message control channel.

[0490] 17) Communication mode indicated by paging control channel.

[0491] For example, a specific field of a paging control channel (such as Paging PDCCH) can be used to directly indicate the target communication mode for receiving a second system message data channel or a second system message control channel. This specific field can be the short message field of the paging control channel.

[0492] For example, the indication field jointly encoded by the paging control channel indicates the target communication mode for receiving the second system message data channel or the second system message control channel. This example could be achieved by jointly indicating the type of second system message to be received (e.g., OSI type) and the target communication mode for receiving the second system message data channel or the second system message control channel in the short message of the paging control channel.

[0493] For example, by using a specific field of the paging control channel, the target communication mode for receiving the second system message data channel or the second system message control channel can be implicitly determined. This example could be that the type of the second system message (such as OSI type) is indicated in the short message of the paging control channel, for instance, whether it is an Earthquake and Tsunami Warning System (ETWS) / Commercial Mobile Alert System (CMAS). If so, the terminal subsequently receives the second system message data channel or the second system message control channel using LP mode.

[0494] 18) Paging data channel or paging data channel communication mode.

[0495] For example, when the paging data channel or the paging data channel indicates that the terminal needs to receive a second system message, the communication mode of the corresponding second system message data channel or second system message control channel is the same as the communication mode of the paging data channel or paging data channel; or according to certain rules, the communication mode of the paging data channel or paging data channel is mapped to the communication mode of receiving the second system message data channel or second system message control channel.

[0496] 19) A paging data channel or a paging data channel resource, the paging data channel or paging data channel being used to indicate the second system message data channel or the second system message control channel.

[0497] The paging data channel or its resources may include at least one of the following: paging occasion index; paging frame index; paging occasion (PO); paging data channel or the time-domain window location of the paging data channel; paging cycle; discontinuous reception (DRX) or discontinuous transmission (DTX) cycle; system information change period; SSB index associated with PO resources; mapping cycle of SSB and PO; mapping method of SSB and PO (e.g., time-domain / frequency-domain priority).

[0498] 20) Communication mode indicated by Wake Up Signaling (WUS).

[0499] For example, triggering the WUS signal of SSB or SIB1, or OSI or PRACH can indicate the communication mode for receiving the second system message data channel or the second system message control channel.

[0500] In this embodiment, the terminal can determine the target communication mode in the above manner, and receive the second system message data channel or the second system message control channel based on the target communication mode, thereby improving the flexibility of receiving the second system message data channel or the second system message control channel, which is conducive to improving the receiving efficiency of the second system message data channel or the second system message control channel or reducing the terminal power consumption.

[0501] In some embodiments, the paging-related information includes a paging data channel, a paging control channel for scheduling the paging data channel, or a paging channel. The processing module 302 is configured to determine a target communication mode from at least two communication modes based on at least one of the following:

[0502] 1) Specific information about the synchronization signal block.

[0503] 2) Communication mode indicated by target cell, carrier, frequency band or subband.

[0504] 3) The communication mode indicated by the target signaling, wherein the paging data channel, the paging control channel, or the paging channel belongs to an undefined cell.

[0505] 4) Receive synchronization signal block, first synchronization signal, second synchronization signal, demodulation reference signal of first broadcast channel or communication mode of first broadcast channel.

[0506] 5) Communication mode indicated by RRC release message.

[0507] 6) Indication information of the first synchronization signal or the second synchronization signal.

[0508] 7) Indication information of the demodulation reference signal of the first broadcast channel.

[0509] 8) Community signage.

[0510] 9) Measurement of the demodulation reference signal of the first synchronization signal, the second synchronization signal, or the first broadcast channel.

[0511] 10) Definition of the first control resource set or search space.

[0512] 11) Definition of TDRA forms or lists.

[0513] 12) DCI instruction.

[0514] Since paging messages can reuse the scheduling mode of first system messages (such as SIB1), the method for determining the target communication mode of the first system message data channel or the first system message control channel can also be used to determine the target communication mode of the paging data channel, the paging control channel, or the paging channel. Therefore, the detailed descriptions of 1) to 12) above can be found in other embodiments.

[0515] 13) Communication mode indicated by the group common control channel.

[0516] For example, a specific value of a field of a group common control channel may be associated with a communication mode for receiving paging data channels, paging control channels, or paging channels; or a field may directly indicate the communication mode for receiving paging data channels, paging control channels, or paging channels.

[0517] The aforementioned group common PDCCH can be, for example, a paging advance indication (PEI), DCI2_7. The fields that can be used for indication include, but are not limited to: paging advance indication search space, paging advance indication frame offset, first PDCCH monitoring Occasion of PEI-O, number of subgroups at paging time (subgroupsNumberPO), and number of paging advance indications at paging time (po-NumberPEI).

[0518] 14) Communication mode indicated by paging control channel.

[0519] For example, the paging control channel indicates a target communication mode for receiving paging data channels or paging channels.

[0520] For example, a specific field of the paging control channel can be used to directly indicate the target communication mode for receiving paging data channels; this specific field could be a short message field.

[0521] For example, the indicator field of the paging control channel, which is jointly encoded, indicates the target communication mode for receiving the paging data channel. For instance, in the short message indicator of the paging control channel, the paging type to be received and the target communication mode for receiving the paging data channel are jointly indicated. For example, 01 corresponds to receiving only the paging data channel, which corresponds to the LP mode; 11 corresponds to receiving both the paging data channel and the short message, which corresponds to the HP mode.

[0522] For example, a specific field in the paging control channel implicitly determines the target communication mode for receiving the paging data channel or the paging channel. This example could be indicated in the short message of the paging control channel, specifying whether it is eMBB; if so, the terminal subsequently receives the paging data channel or the paging channel in HP mode.

[0523] 15) Communication mode of paging control channel.

[0524] For example, the communication mode of receiving the paging data channel or the paging channel is the same as the communication mode of receiving the paging control channel; or according to certain rules, the communication mode used to receive the paging control channel is mapped to the communication mode used to receive the paging data channel or the paging channel.

[0525] 16) Resources for receiving paging messages.

[0526] The resource for receiving paging messages may include at least one of the following: paging occasion index; paging frame index; paging occasion (PO), paging data channel, or the time-domain window position of the paging data channel; paging cycle; discontinuous reception (DRX) or discontinuous transmission (DTX) cycle; system information modification period; SSB index associated with the PO resource; mapping cycle between SSB and PO; mapping method between SSB and PO (e.g., time-domain / frequency-domain priority).

[0527] 17) Communication mode indicated by WUS.

[0528] For example, triggering the WUS signal of SSB or SIB1, or OSI or PRACH can indicate the communication mode for receiving paging data channels, paging control channels or paging channels.

[0529] In this embodiment, the terminal can determine the target communication mode in the above manner, and receive the paging data channel, paging control channel or paging channel based on the target communication mode, thereby improving the flexibility of receiving the paging data channel, paging control channel or paging channel, which is conducive to improving the receiving efficiency of the paging data channel, paging control channel or paging channel or to reducing the terminal power consumption.

[0530] In some embodiments, the processing module 302 is further configured to determine a target communication mode from at least two communication modes based on at least one of the following:

[0531] 1) The first time required to switch from the first communication mode to the first communication mode.

[0532] For example, the multiple migration times required to switch from the current communication mode to multiple different communication modes.

[0533] 2) The second time required to switch from the non-second communication mode to the second communication mode.

[0534] For example, the multiple migration times required to switch from multiple different communication modes to the intent communication mode.

[0535] 3) The third time required to switch from the first communication mode to the second communication mode.

[0536] For example, the time required to switch from the current communication mode to the intended communication mode; in particular, the third time can be the sum of the migration-out time and migration-in time mentioned above.

[0537] 4) The first time difference between the first signal and the second signal, wherein the first signal is a signal received or transmitted in the first communication mode, the second signal is a signal received or transmitted in the second communication mode, and the start time of the second signal is not earlier than the start time of the first signal.

[0538] For example, the first time difference can be the time difference or minimum time interval from the end / start of the first signal reception or transmission to the start / end of the second signal reception or transmission.

[0539] 5) Determine the communication mode to be used based on the first condition.

[0540] The first communication mode and the second communication mode are included in the at least two communication modes.

[0541] In some embodiments, the processing module 302 is further configured to determine the communication mode to be used based on a first condition, including at least one of the following:

[0542] 1) If the first time difference is less than or not greater than the fourth time, then the first communication mode or the default communication mode is used, wherein the fourth time is the first time, the second time, and T. _gap The sum of.

[0543] 2) If the first time difference is less than or not greater than the fifth time, then determine whether to use the first communication mode or the default communication mode, where the fifth time is the third time and T. _gap The sum of.

[0544] 3) If the first time difference is greater than or not less than the fourth time, then the second communication mode is determined to be used, wherein the fourth time is the first time, the second time, and T. _gap The sum of.

[0545] 4) If the first time difference is greater than or not less than the fifth time, then the second communication mode is determined to be used, wherein the fifth time is the third time and T. _gap The sum of.

[0546] Wherein, the default communication mode belongs to the communication modes supported by the terminal, and the T _gap This value is independent of the first time, the second time, and the third time. It includes, but is not limited to: a specific constant, such as 0; BWP switching time; radio frequency (RF) readjustment time; band switching time; beam switching time; and control information (including DCI / MAC CE / RRC signaling) interpretation time.
