Description

Information sending method, receiving method, terminal, network device and storage medium

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202410374840.8 filed in China on March 29, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of mobile communication technology, and in particular to an information sending method, a receiving method, a terminal, a network device, and a storage medium. Background Art

[0004] Currently, network energy-saving solutions for mobile communication systems primarily rely on spatial or power-based energy-saving technologies. Spatial adaptation, for example, primarily adjusts the number of ports or panels used when a base station transmits downlink physical downlink shared channels (PDSCHs), thereby reducing base station energy consumption. Power adaptation, on the other hand, reduces the actual transmit power of PDSCH traffic channels during downlink transmission, thereby reducing energy consumption.

[0005] The aforementioned energy-saving measures are all implemented when scheduling user equipment (UE). However, under low-load conditions, cell-level signals such as synchronization signal blocks (SSBs), channel state information (CSI) reference signals (CSI-RSs), paging, and random access channel occasions (ROs) are still transmitted and received according to target periods. This results in significant energy consumption for the base station, both in transmission and reception. For example, SSBs must be transmitted at a period of at least 20ms, or two frames, even when there are few users and traffic is low. To ensure UE access to the cell, SSBs are typically transmitted with a 20ms period. During uplink RACH occasions, the base station needs to receive the preamble, requiring reception on all physical random access channel (PRACH) occasions, resulting in significant uplink energy consumption.

Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0136] The terms "first", "second", etc. in the specification and claims of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

The techniques described herein may be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes an NR system for example purposes, and NR terminology is used in most of the following description, although these techniques may also be applicable to applications other than NR system applications.

[0138] The following description provides examples and does not limit the scope, applicability, or configuration set forth in the claims. The functions and arrangements of the elements discussed may be changed without departing from the scope of this disclosure. The various examples may appropriately omit, substitute, or add various procedures or components. For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

[0139] Please refer to Figure 1, which shows a block diagram of a wireless communication system applicable to embodiments of the present disclosure. The wireless communication system includes a terminal 11 and a network device 12. Terminal 11 may also be referred to as a user terminal or user equipment (UE). Terminal 11 may be a terminal-side device such as a mobile phone, tablet personal computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or vehicle-mounted device. It should be noted that the specific type of terminal 11 is not limited in the embodiments of the present disclosure. The network device 12 may be a base station and / or a network node, wherein the base station may be a base station of the fifth generation mobile communication technology (5G) and later versions (e.g., the next generation Node B (gNB), 5G NR Node B (Node B, NB), etc.), or a base station in other communication systems (e.g., evolved Node B (eNB), wireless local area network (WLAN) access point, or other access point, etc.), wherein the base station may be referred to as a node B, an evolved node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), or a base station in a cellular network. The base station is not limited to a specific technical vocabulary as long as the same technical effect is achieved. It should be noted that in the embodiment of the present disclosure, only the base station in the NR system is used as an example, but the specific type of the base station is not limited. The network node can be a base station, a relay node, an integrated access and backhaul (IAB) device or a network-controlled repeater (NCR), etc.

[0140] The base station can communicate with the terminal 11 under the control of a base station controller, which in various examples can be part of the core network or certain base stations. Some base stations can communicate control information or user data with the core network via a backhaul. In some examples, some of these base stations can communicate with each other directly or indirectly via a backhaul link, which can be a wired or wireless communication link. The wireless communication system can support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on these multiple carriers simultaneously. For example, each communication link can be a multi-carrier signal modulated according to various radio technologies. Each modulated signal can be sent on a different carrier and can carry control information (e.g., reference signals, control channels, etc.), overhead information, data, etc.

[0141] The base station can communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of ​​an access point can be divided into sectors that constitute only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

[0142] A communication link in a wireless communication system may include an uplink for carrying uplink (UL) transmissions (e.g., from terminal 11 to network device 12), or a downlink for carrying downlink (DL) transmissions (e.g., from network device 12 to terminal 11). UL transmissions may also be referred to as reverse link transmissions, while DL transmissions may also be referred to as forward link transmissions. Downlink transmissions may be performed using a licensed frequency band, an unlicensed frequency band, or both. Similarly, uplink transmissions may be performed using a licensed frequency band, an unlicensed frequency band, or both.

[0143] Currently, RACH reception is performed periodically (or the UE transmits periodically). The specific reception resources can be found in related technologies. This long-term, periodic reception requires the base station to be constantly awakened, powered on, and operating to perform periodic reception. Between each reception or transmission of the common reference signal, the base station cannot enter deep sleep, thus preventing further energy savings.

[0144] For another example, as shown in Figure 2, for SSB, in the related art, the UE searches for SSB according to a 20ms period during initial access. Similarly, as shown in Figure 3, paging messages are also sent according to a certain period. Paging resources include paging frames and paging occasions, etc. Since all paging resources are sent according to a period and are distributed throughout the time window, it is difficult for the base station to completely enter the uplink sleep state. With a period of 32 radio frames, if there are 8 paging frames in a period, downlink transmission is performed according to a period of 32 / 8=4 radio frames, which is equivalent to downlink transmission every 4 radio frames. It is difficult for the base station to enter deep sleep. From the above, it can be seen that it is difficult for the base station of the related art to enter deep sleep during periodic transmission.

[0145] To solve at least one of the above problems, an embodiment of the present disclosure provides an information sending method, which reduces the power consumption of the network device while ensuring normal access of the UE by introducing an idle state or sleep state working mode of the network device.

[0146] Referring to FIG. 4 , an information sending method provided by an embodiment of the present disclosure, when applied to a network device, includes:

[0147] Step 41: Send first configuration information of a first cell to a first terminal.

[0148] Here, the first configuration information is used to configure a time window, and the first cell supports at least one of the following behaviors within the time window: synchronization, random access, and paging.

[0149] The first cell may be a target cell for cell reselection or cell handover of the first terminal, or a current serving cell of the first terminal, or a cell in which the first terminal is stationed. The time window may be a periodic time window, or the time window may be a duration, for example, a period of a preset length.

[0150] Through the above steps, the embodiment of the present disclosure can send the first configuration information so that the first terminal obtains the relevant configuration of the time window. In this way, the first terminal can perform synchronization, random access, and paging operations within the time window, and at other times outside the time window, the first cell can enter a dormant state, or not perform synchronization, random access, or paging operations outside the time window, thereby reducing the power consumption of the network device. Since synchronization, random access, and paging operations are supported within the time window, the embodiment of the present disclosure can reduce the power consumption of the network device while ensuring normal access of the UE. When there is no explicit configuration, the time window can be 1024 system frames. Or the time window can be 1024 system frames.

[0151] The random access may also be sending a PRACH or a preamble to the target cell.

[0152] Specifically, the first configuration information includes at least one of the following:

[0153] A) The first period of the time window;

[0154] B) a first duration of the time window;

[0155] C) the first time offset of the time window;

[0156] D) first SSB configuration information;

[0157] E) first paging resource configuration information;

[0158] F) first random access opportunity (RO) configuration information;

[0159] G) Configuration information of the first random access.

[0160] Among them, the first period is the period of the time window. The first duration refers to the time length of the time window. The first time offset refers to the offset of the time window relative to the reference position. The first SSB configuration information is the SSB configuration information related to the time window, or the SSB configuration information within the time window, or the configuration information of the SSB synchronized within the time window. The first paging resource configuration information is the paging resource configuration information related to the time window, or the paging resource configuration information within the time window, or the configuration information of the resources for paging within the time window. The first RO configuration information is the RO configuration information related to the time window, or the RO configuration information within the time window, or the configuration information of the RO for random access within the time window. In addition, the first RO configuration information and / or the first random access configuration information can be broadcast or sent by system message.

[0161] Figure 5 provides an example of a time window according to an embodiment of the present disclosure, wherein the dotted box represents the time window, and each dark gray square represents a paging frame or paging opportunity within the time window. Alternatively, each dark gray square may represent multiple SSBs within a time window. As can be seen from Figure 5, when a network device is configured with the time window, the network device can enter deep sleep during the time between adjacent time windows, thereby reducing the power consumption of the network device. Therefore, in the embodiment of the present disclosure, the operating state of the network device configured with the time window is referred to as the energy-saving state.

[0162] FIG6 provides two application scenarios of the above-described method according to an embodiment of the present disclosure. In Scenario 1, a first terminal switches from its original location in the second cell to the first cell through cell handover or cell reselection. In Scenario 2, while the first terminal is stationed in the first cell, the first cell switches from a normal operating state to an energy-saving state. In FIG6 , the dark gray blocks in the first cell represent time windows within which SSBs can be received; the dark gray blocks in the second cell represent SSBs. It can be seen that the SSB transmission density of the second cell is higher than that of the first cell. In other words, the second cell is a cell in a normal operating state or a non-energy-saving state that periodically transmits SSBs. The first cell is a cell that has entered an energy-saving state. Specifically, the second cell can be an anchor cell, and the first cell can be a non-anchor cell used for energy saving. Alternatively, the second cell is a cell in a normal operating state, while the first cell is a cell in an energy-saving state and is a neighboring cell of the second cell. The terminal can obtain configuration information of the first cell based on information provided / sent by the second cell. In the embodiment of the present disclosure, the second cell may be a primary cell (PCell) or an anchor cell in a multi-carrier, and the first cell may be a secondary cell (SCell) or a non-anchor cell in a multi-carrier.

[0163] In the case where the first terminal needs to reselect or switch from the second cell to the first cell (scenario 1), the embodiment of the present disclosure may execute the above step 41 to send the first configuration information of the first cell to the first terminal. In this case, the above step 41 may include at least one of the following:

[0164] (1) The second cell sends the first configuration information to the first terminal, and the second cell may be a serving cell of the first terminal. Here, the second cell may be an anchor cell of the first terminal. Specifically, the second cell may send at least one of Radio Resource Control (RRC) signaling, Downlink Control Information (DCI), SSB, and system message to the first terminal, and at least one of the RRC information, DCI, SSB, and system message includes indication information of the first configuration information or a receiving location of the first configuration information or a receiving resource of the first configuration information (such as a time-frequency resource for receiving the first configuration information), so that the first terminal can receive the first configuration information according to the receiving location or time-frequency resource of the first configuration information.

[0165] (2) The first cell sends the first configuration information to the first terminal through a configuration message or system information. Here, the first cell is a target cell for cell reselection or cell switching of the first terminal, and the first cell may be a non-anchor cell of the first terminal. The system information may be a system information block (SIB), and the target cell may be an energy-saving cell or a cell that performs discontinuous transmission and / or discontinuous reception. In the embodiment of the present disclosure, the serving cell of the first terminal may also send the first configuration information to the first terminal through a configuration message or system information.

[0166] When the first configuration information is sent to the first terminal via the second cell, the first configuration information may further include: a system frame number (SFN) offset between the second cell and the first cell; or, the second cell sends first indication information or another configuration information to the first terminal, and the first indication information or another configuration information includes the system frame number (SFN) offset between the second cell and the first cell. In this way, the first terminal can obtain the SFN number of the target cell (or the first cell) based on the SFN number of the second cell (or the current cell), and determine at least one of the start time, duration, and end time of the time window based on the first configuration information.

[0167] In the case where the first cell where the first terminal resides needs to enter an energy-saving state (scenario 2), the embodiment of the present disclosure may execute the above-mentioned step 41 to send the first configuration information of the first cell to the first terminal. At this time, the above-mentioned step 41 may be: the first cell sends the first configuration information to the first terminal, wherein the first cell is the cell where the first terminal resides or the current serving cell. Specifically, the first cell may send at least one of RRC information, DCI, SSB and system messages to the first terminal, and at least one of the RRC information, DCI, SSB and system messages includes the first configuration information or indication information of the reception resource of the first configuration information, so that the first terminal can receive the first configuration information according to the reception resource of the first configuration information.

[0168] In another application scenario (scenario 3) of an embodiment of the present disclosure, a second cell sends first configuration information of the first cell to a first terminal. Here, the second cell is a cell different from the first cell. The second cell may send at least one of Radio Resource Control (RRC) information, Downlink Control Information (DCI), SSB, and system messages to the first terminal. At least one of the RRC information, DCI, SSB, and system messages may include the first configuration information or the receiving position of the first configuration information or the indication information of the receiving time-frequency resources, so that the first terminal can receive the first configuration information according to the receiving position or time-frequency resources of the first configuration information. In this way, the first terminal performs random access to the first cell based on the first configuration information, or sends PRACH or preamble. After receiving the PRACH or preamble, the first cell sends a system information block, such as SIB1 information. The first cell may send the system information block continuously or according to the duration indicated by the first time window.

[0169] In an embodiment of the present disclosure, the network device may superimpose energy-saving configuration information or first configuration information on the basis of the third configuration, such as superimposing the first period and duration of the above-mentioned time window. The third configuration may be a resource configuration of the related technology, for example, the third configuration is at least one of the paging configuration, SSB configuration, and RACH configuration in 3GPP release 15 or release 16. In this way, the paging, SSB, and RACH in the third configuration or the first configuration information only work within the time window. That is, for example, in an idle or energy-saving state, only the SSB resources, paging resources (frames or occasions), and RACH occasions within the time window are considered to be working or active or valid. Outside the time window, the network device enters a dormant state. Or outside the time window, SSB reception or paging reception is not performed, or RACH transmission is not performed.

[0170] For example, the network device or the first terminal calculates a paging frame or paging opportunity according to the paging frame calculation method of the third configuration, and then intersects the first time window (or activation time window) with the paging frame or paging opportunity. In this way, the network device only sends paging on the paging frames or paging opportunities within the time window, and the first terminal only monitors the paging frames or paging opportunities within the time window to receive paging. The network device does not send paging outside the time window.

[0171] In addition, the embodiments of the present disclosure may also define time window behaviors of each channel in an idle or energy-saving state, such as paging frames and paging occasions.

[0172] In the disclosed embodiment, the network device may further determine a first paging resource for the first cell based on the first paging resource configuration information. The first paging resource is a lower paging resource for the first cell in a first state or a first configuration, where the first state is a preset energy-saving state, and the first configuration is a configuration corresponding to the first configuration information. The first paging resource within the time window is then determined as a second paging resource, and the first cell then sends a paging message based on the second paging resource.

[0173] Specifically, as shown in FIG7 , in an embodiment of the present disclosure, the first period of the time window may be X times the paging period, the first duration of the time window may be Y times the paging period, and the first time offset of the time window may be an offset from the starting position of the time window; wherein X and Y are both integers greater than or equal to 1, and Y is less than or equal to X. Alternatively, the first period, first duration, and first time offset are defined based on a predetermined time unit. The time unit may be a frame, a time slot, or a symbol.

[0174] As shown in Figure 7, paging occurs during paging frames or paging occasions within the time window (as indicated by dark gray blocks), and the UE monitors or receives paging. However, during paging frames or paging occasions outside the time window (as indicated by blank blocks), the base station either does not send paging or the terminal does not need to monitor or receive paging. This allows the base station to sleep for the remainder of each first cycle, excluding the time window, to reduce power consumption.

[0175] Here is a specific example. The example is as follows:

[0176] 1. Define the time window;

[0177] Define a time unit, assuming a paging cycle as a time unit. The first cycle of the time window is N1*paging cycle, and the offset (Offset) is the SFN offset, or the offset of multiplexing paging. Assume that the radio frame or system frame at the starting point of the time window = (SFN+offset) mod (N1*cycle), where cycle can specifically be a discontinuous reception cycle (DRX cycle) or a paging cycle; in addition, the duration (Duration) of the time window is N2*paging cycle.

[0178] Then when N1=10, N2=2:

[0179] The calculation can be performed based on multiples of the paging cycle. Each time window is two paging cycles, and the first cycle of the time window is 10 paging cycles. The network device only sends paging during the first and second paging cycles. The terminal only monitors during the first and second paging cycles. Taking Figure 8 as an example, the network device does not send paging during the third to tenth paging cycles, and the terminal does not monitor paging. In Figure 8, #n represents the n+1th paging cycle. Each paging cycle includes multiple paging frames or paging opportunities, as shown by the dark gray squares.

[0180] Because the paging opportunities for each terminal are typically evenly distributed across multiple time slots based on the terminal identifier (UE ID), the time window period setting may affect the paging of some terminals. For example, if a terminal's paging opportunity falls outside the time window or is inactive, the terminal cannot receive its paging information. As shown in Figure 9, blocks 1, 2, 3, and 4 represent the paging opportunities for terminals 1, 2, 3, and 4, respectively. The paging opportunities for terminals 3 and 4 fall outside the time window (dashed box), and therefore cannot receive paging.

[0181] To ensure service fairness for each terminal, the embodiment of the present disclosure forms multiple paging clusters, with each cluster performing a periodic cycle according to the first period of the time window. Each cluster includes multiple paging frames, and these paging frames / paging opportunities can initiate paging for all terminals. Specifically, the embodiment of the present disclosure can form multiple clusters in the following manner:

[0182] The network device calculates the frame number of the paging frame of the first terminal based on the first period of the time window, the first duration of the time window, the system frame number of the first cell, the total number of paging frames and the ID information of the first terminal, and determines the paging frame of the first terminal; then the first cell pages the first terminal on the paging frame of the first terminal.

[0183] Specifically, the frame number of the paging frame of the first terminal satisfies one of the following formulas: (SFN+offset)mod T1=(T2 div N)*(UE_ID mod N); (SFN+offset)mod T1=((T2 mod M)div N)*(UE_ID mod N);

[0184] Among them, T1 represents the first period, T2 represents the first duration of the first time window, SFN represents the system frame number of the paging frame of the first terminal in the first cell, offset is the offset of the system frame number between the second cell and the first cell, or the offset of the paging frame, N represents the total number of paging frames, UE_ID represents the ID information of the first terminal, M is a preset second period or group, and is a preset positive integer greater than or equal to 1.

[0185] For example, in one example of the present disclosure, offset = 0, T1 = 1024, T2 = 16, N = 4, and UE id = {0, 1, 2, 3}, then the paging frames corresponding to UE ids 0, 1, 2, and 3 are frames 0, 4, 8, and 12, respectively, and are cycled according to a period of 1024 frames. Referring to Figure 5 , each UE corresponds to a paging frame (dark gray square) within T2 and cycles according to the first period of T1 = 1024 frames.

[0186] In addition, the paging frame offset, or the offset in the above formula, may be greater than K SSB periods or greater than K*number of frames Y. Here, number of frames Y is the number of system frames corresponding to one SSB period. For example, an SSB period of 20ms or 40ms corresponds to two or four system frames, respectively. Here, K is an integer.

[0187] This allows the UE to acquire synchronization after performing multiple SSB measurements or tracking, and improves the success rate of demodulation at the paging location. After multiple synchronizations, while ensuring synchronization performance, DL data can be correctly demodulated. An example is shown in Figure 10, where light-colored squares represent SSBs and dark-colored squares represent paging frames or paging opportunities.

[0188] In the disclosed embodiment, the network device may also determine the third paging resource based on the paging configuration information within the time window; then, the first cell sends a paging message based on the third paging resource, or the terminal receives a paging message based on the third paging resource.

[0189] In the related art, there is a mapping relationship between SSB and RACH, and SSB is mapped to the corresponding RO. The traditional mapping method is to start the calculation from frame 0 and then map it to the 1023rd frame. For traditional idle UEs, this mapping method does not cause any problems, because SSB will always be sent and the network equipment will always be received. However, network equipment in energy-saving state will not always send SSB (network equipment will not always receive RACH), so if the traditional mapping relationship is followed, the UE needs to calculate the mapping relationship of all 1024 frames before it can start working. This poses a challenge for UEs that want to access network equipment in energy-saving state in a relatively short period of time.

[0190] In addition, if the corresponding RO is intercepted according to the above-mentioned method of adding a time window (active window), it is also very likely that the RO corresponding to some SSBs will fall outside the time window.

[0191] To this end, in an embodiment of the present disclosure, the network device may also map the SSB and RO of the first cell according to the first SSB configuration information and / or the first uplink RO configuration information, and determine the RO; and then receive the PRACH sent by the first terminal on the RO. Here, the first SSB configuration information may be SSB configuration information in a power-saving state or a discontinuous transmission state or a preset first state. The first uplink RO configuration information may be RO configuration information in a power-saving state or a discontinuous transmission state or a preset first state. The first SSB configuration information is used to indicate the sending position of the SSB, and may specifically be ssb-PositionsInBurst information.

[0192] The network device may also map the SSB to the RO based on the first system frame, and then receive the PRACH sent by the first terminal on the RO. The first system frame is configured by the first configuration information, or configured by the second configuration information sent by the network device or indicated or configured by system information. The SSB may be a synchronization signal and physical broadcast channel block (SS / PBCH block), and the RO may also be a physical random access channel opportunity (PRACH Occasion).

[0193] Here, the first system frame is the system frame in which the second cell configures the first terminal to synchronize with the first cell or measure SSB. For example, cell 1 configures the UE to synchronize on frame X, or measure SSB, and the UE starts calculating the mapping of SSB and RO according to the indicated frame X. At this time, starting from system frame X, the association period is calculated or obtained. Among them, within an association period, N SSB indices are mapped to multiple RACH occasions (multiple is reflected in RACH occasions, where occasion is plural) at least once. The SSB information is given from the above configuration information, and PRACH related information can also be given from the above configuration information.

[0194] Alternatively, the first system frame is the system frame in which the first SSB in the time window is located. For example, the UE synchronizes with cell 2 based on the SFN offset and the indicated time window information. After synchronization, the UE can know the corresponding frame number and the starting frame of the time window. In this way, the UE can obtain the time window information based on the information of the starting point of the acquired active window, the frame number obtained through the SSB, and the period of the SSB, thereby obtaining the starting frame number.

[0195] Alternatively, the first system frame is the starting frame of the time window. For example, the UE calculates the SFN number of cell 2 based on the SFN offset, and calculates the frame number of the starting time window according to the configuration information of the time window, such as the offset, duration, and first period, and obtains the mapping relationship between SSB and RO based on the frame number. Then, according to SFN mod period = offset, the corresponding SFN is the starting frame (starting from frame X) of the above-mentioned SSB and RO mapping relationship.

[0196] The frame X may be indicated in configuration information or other information.

[0197] In related technologies, there is a mapping relationship between SSBs and ROs, which defines an association period and an association pattern period. In the disclosed embodiments, all SSBs are mapped to ROs within an association period. An association pattern period can contain one or more association periods.

[0198] In an embodiment of the present disclosure, when the window duration or window length does not completely include an association period or association pattern period, the active window can optionally be extended to include the remaining ROs. The UE considers that the ROs that are after the time window but still within an association period (or association pattern period) can (still) perform uplink transmission. That is, when the first duration of the time window is less than an association period (association period) or association pattern period (association pattern period), the network device can also receive the PRACH sent by the first terminal on the RO of the first terminal that exceeds the time window.

[0199] When the first duration of the time window is greater than p association cycles or association pattern cycles and less than p+1 association cycles or association pattern cycles, the network device performs mapping of the SSB and the RO respectively in the first p association cycles within the time window, and does not configure the RO in the remaining window length after the first p association cycles within the time window; or when the first duration of the time window is greater than p association cycles or association pattern cycles and less than p+1 association cycles or association pattern cycles, the network device performs mapping of the SSB and the RO respectively in the first p association cycles within the time window, and does not perform mapping of the SSB and the RO in the remaining window length after the first p association cycles within the time window. Here, p is an integer greater than or equal to 1.

[0200] In addition, when the mapping of SSB and RO exceeds the deadline of the time window, or when the mapping of SSB and RO exceeds the end (end or ending) of the time window, or when the mapping of SSB and RO is after the time window, the network device does not receive PRACH on the RO after the deadline or end of the time window.

[0201] In an embodiment of the present disclosure, after the network device receives the PRACH sent by the terminal within the time window, the network device can be restored from the energy-saving mode to the normal working mode. Specifically, the normal working mode may refer to: the base station sends the system information block (SSB) according to a preset period, for example, sends the SSB according to a period of 20ms or 2frame, and sends the master system information block (Master Information Block, MIB) and / or system information block (System Information Block, SIB) information, and receives the uplink signal on the corresponding uplink time slot. That is to say, in an embodiment of the present disclosure, when the network device receives the PRACH within the time window, the first cell can perform downlink transmission and / or uplink reception, and here, the downlink transmission may include the transmission of the system information block.

[0202] Referring to FIG. 11 , an information sending method provided by an embodiment of the present disclosure, when applied to a first terminal, includes:

[0203] Step 111: Receive first configuration information of a first cell sent by a network.

[0204] Here, the first cell supports at least one of the following behaviors in the time window: synchronization, random access, and paging. The first configuration information is used to configure the time window.

[0205] Step 112: determining the time window according to the first configuration information;

[0206] Through the above steps, the embodiment of the present disclosure can enable the first terminal to obtain the relevant configuration of the time window by sending the first configuration information, so that the first terminal can perform synchronization, random access, and paging operations within the time window, and at other times outside the time window, the first cell can enter a sleep state to reduce the power consumption of the network equipment, and can also ensure the normal access of the UE.

[0207] Specifically, the first configuration information includes at least one of the following: the first period of the time window, the first duration of the time window, the first time offset of the time window, the first SSB configuration information, the first paging resource configuration information, the first random access timing RO configuration information, and the first random access configuration information.

[0208] Specifically, when the first terminal needs to reselect or switch from the second cell to the first cell (scenario 1), in the above step 111, receiving the first configuration information of the first cell sent by the network may include at least one of the following:

[0209] (1) Receiving the first configuration information sent by a second cell, where the second cell is a serving cell of the first terminal. Here, the second cell may be an anchor cell of the first terminal. Specifically, the first terminal may receive at least one of RRC information, DCI, SSB, and system messages sent by the second cell, where the at least one of the RRC information, DCI, SSB, and system messages includes the first configuration information or information indicating a receiving location or receiving resource of the first configuration information; and then obtaining the first configuration information based on at least one of the RRC information, DCI, SSB, and system messages.

[0210] (2) Receiving the first configuration information sent by the first cell through a configuration message or system information, where the first cell is a target cell. Here, the first cell is a target cell for cell reselection or cell switching of the first terminal, and the first cell may be a non-anchor cell of the first terminal. The system information may be a system information block (SIB), and the target cell may be an energy-saving cell or a cell that performs discontinuous transmission and / or discontinuous reception. In the embodiment of the present disclosure, the serving cell of the first terminal may also send the first configuration information to the first terminal through a configuration message or system information.

[0211] When the first configuration information is sent to the first terminal via the second cell, the first configuration information may further include: an SFN offset between the second cell and the first cell; or, the first terminal receives first indication information sent by the second cell to the first terminal, where the first indication information or the first configuration information includes the SFN offset between the second cell and the first cell. In this way, the first terminal can determine the system frame number of the first cell based on the SFN offset between the second cell and the first cell and the system frame number of the second cell; and further determine the time window based on the system frame number of the first cell and the first configuration information.

[0212] In the case where the first cell where the first terminal resides needs to enter an energy-saving state (scenario 2), in the above-mentioned step 111, receiving the first configuration information of the first cell sent by the network may specifically include: the first terminal receiving the first configuration information sent by the first cell, wherein the first cell is the cell where the first terminal resides. Specifically, the first terminal may receive at least one of RRC information, DCI, SSB, and system messages sent by the first cell, wherein at least one of the RRC information, DCI, SSB, and system messages includes the first configuration information or indication information of a receiving location or receiving resource of the first configuration information; and then obtain the first configuration information based on at least one of the RRC information, DCI, SSB, and system messages.

[0213] In the disclosed embodiment, the first terminal may further determine, based on the first paging resource configuration information, the first paging resource of the first cell in a first state or a first configuration, where the first state refers to a preset energy-saving state, and the first configuration corresponds to the first configuration information; the first terminal determines the first paging resource within the time window as a second paging resource; and then receives a paging message sent by the first cell based on the second paging resource. In other words, the first terminal obtains the actual paging position by intersecting the position of the legacy paging with the time window.

[0214] Optionally, the first period of the time window may be X times the paging period, the first duration of the time window may be Y times the paging period, and the first time offset of the time window may be an offset from the starting point of the time window; wherein X and Y are both integers greater than or equal to 1, and Y is less than or equal to X. Alternatively, the first period, first duration, and first time offset are defined based on a predetermined time unit. The time unit may be a frame or a time slot.

[0215] In an embodiment of the present disclosure, the first terminal can also calculate the frame number of the paging frame of the first terminal based on the first cycle, the first duration of the time window, the system frame number of the first cell, the total number of paging frames and the ID information of the first terminal, and determine the paging frame of the first terminal; and then receive the paging message sent by the first cell on the paging frame of the first terminal.

[0216] Here, the frame number of the paging frame of the first terminal satisfies one of the following formulas: (SFN+offset)mod T1=(T2 div N)*(UE_ID mod N); (SFN+offset)mod T1=((T2 mod M)div N)*(UE_ID mod N);

[0217] Among them, T1 represents the first period, T2 represents the first duration of the first time window, SFN represents the system frame number of the paging frame of the first terminal in the first cell, offset is the offset of the system frame number between the second cell and the first cell, or the offset of the paging frame, N represents the total number of paging frames, UE_ID represents the ID information of the first terminal, M is a preset second period or group, and is a preset positive integer greater than or equal to 1.

[0218] In addition, the first terminal may also determine the third paging resource according to the paging configuration information of the time window; and then receive the paging message sent by the first cell on the third paging resource.

[0219] Optionally, the first terminal may also map the SSB and RO of the first cell according to the first SSB configuration information and / or the first random access opportunity RO configuration information, and determine the RO; and then send PRACH on the RO.

[0220] Optionally, the first terminal can also map SSB and RO based on the first system frame; and then send PRACH on the RO; here, the first system frame is configured through the first configuration information, or configured through the second configuration information sent by the network or the system information indication or configuration.

[0221] Specifically, the first system frame may be a system frame in which the second cell configures the first terminal to synchronize with the first cell or measure SSB; or, the first system frame is a system frame in which the first SSB in the time window is located; or, the first system frame is the starting frame of the time window.

[0222] Optionally, the first terminal may also send a PRACH on the RO of the first terminal that exceeds the time window when the first duration of the time window is less than an association period or an association pattern period.

[0223] Optionally, the first terminal may further, when the first duration of the time window is greater than p association cycles or association pattern cycles and less than p+1 association cycles or association pattern cycles, respectively perform SSB and RO mapping in the first p association cycles within the time window, wherein no RO is configured in the remaining window length after the first p association cycles in the time window. Alternatively, the first terminal may, when the first duration of the time window is greater than p association cycles or association pattern cycles and less than p+1 association cycles or association pattern cycles, respectively perform SSB and RO mapping in the first p association cycles within the time window, wherein no SSB and RO mapping is configured in the remaining window length after the first p association cycles in the time window. Here, p is an integer greater than or equal to 1.

[0224] In addition, in an embodiment of the present disclosure, when the first terminal performs mapping of SSB and RO beyond the deadline or end of the time window or after the time window, it does not send PRACH on the RO after the deadline or end of the time window.

[0225] In addition, when the first terminal sends the PRACH within the time window, the first terminal performs uplink transmission and / or downlink reception with the first cell, wherein the downlink reception may include reception of a system information block.

[0226] The above describes various methods of the embodiments of the present disclosure. The following further provides apparatuses for implementing the above methods.
