Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an information processing method, apparatus, readable storage medium, and chip. Background Technology

[0002] In 5G New Radio (NR) systems, for terminals in Radio Resource Control (RRC) idle mode, during initial access, the terminal assumes that the period of the Synchronization Signal and Physical Broadcast Channel (PBCH) block (SSB) burst set transmitted by the base station is 20ms. To meet the initial access requirements of RRC idle-mode terminals, network equipment (such as base stations) must continuously transmit SSB burst sets at a period of no less than 20ms on the primary serving cell (PCell). Thus, even if there are no users in the area covered by the base station, or the traffic load is low, the base station still needs to transmit an SSB burst set at least once every 20ms. This prevents the base station from entering deep sleep mode, affecting its energy-saving performance.

[0003] If the base station sends the SSB burst set for initial terminal access at a higher period, such as 80ms or 160ms, it can indeed achieve better base station energy saving. However, for the terminal, it generally needs to receive multiple SSB burst sets to complete the decoding of the Physical Broadcast Channel (PBCH), which will lead to higher initial terminal access latency and affect the user experience.

[0004] Therefore, how to reduce the energy consumption of network devices while reducing the initial access latency of terminals is a technical problem that needs to be solved. Summary of the Invention

[0069] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0070] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0071] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0072] This application provides an information processing method and apparatus to reduce the energy consumption of network devices and decrease the initial access latency of terminals.

[0073] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0074] See Figure 1 , Figure 1 This is a flowchart of an information processing method provided in an embodiment of this application, applied to a terminal, such as... Figure 1 As shown, it includes the following steps:

[0075] Step 101: Obtain the configuration information of the first signal.

[0076] Step 102: Send the first signal to the network device according to the configuration information of the first signal.

[0077] The methods for obtaining the configuration information of the first signal include one or more of the following:

[0078] Receive a first target signal or channel, the first target signal or channel being used to indicate configuration information of the first signal; a predefined method; a preconfigured method.

[0079] The first signal is used to trigger the network device to send or receive a second target signal or channel, the second target signal or channel being used for at least one of cell search, initial access, random access, and paging.

[0080] In this embodiment, the terminal acquires configuration information of a first signal and sends the first signal according to the configuration information. The first signal triggers the transmission or reception of a second target signal or channel. Since the terminal acquires configuration information of the first signal, it can acquire the configuration information and send the first signal over a longer period. This allows the network device more time to enter a deep sleep state when it does not receive the first signal sent by the terminal, thus achieving energy saving. At the same time, since the second target signal or channel is triggered by the terminal to send or receive, the terminal's access latency can also be reduced.

[0081] In one embodiment of this application, the terminal may receive a first target signal or channel periodically transmitted by a network device. The period may be 80ms, 160ms, etc. Alternatively, the configuration information of the first signal may be pre-configured or predefined on the terminal. By combining the above methods, partial content of the configuration information can be obtained through different methods, while the complete content of the configuration information can be obtained through a combination of multiple methods.

[0082] The first target signal or channel includes at least one signal or channel selected from the following: a first SSB set, a first synchronization signal (SS) set, and a first channel set. The second target signal or channel includes at least one signal or channel selected from the following: a second SSB set, a second SS set, and a first on-demand set.

[0083] The first SSB set includes Always-On SSBs (AO-SSB), the first SS set includes Always-On Sync Signals (AO-SS), and the first channel set includes Physical Downlink Indication Channels (PDICH). The second SSB set includes On-Demand SSBs (OD-SSB), the second SS set includes On-Demand SSs (OD-SS), and the first On-Demand set includes one or more of the following:

[0084] OD-SSB; OD-SS; On Demand Physical broadcast channel (OD-PBCH); On Demand System Information Block 1 (OD-SIB1); On Demand System Information (OD-SI); On Demand Physical Random Access Channel (OD-PRACH); On Demand paging (OD-paging).

[0085] In one application scenario of this application embodiment, for an idle terminal, the second SSB set or the first on-demand set is used for the initial access of the terminal; for a connected terminal, the second SSB set or the second SS set is used to assist the terminal in maintaining time-frequency synchronization and performing L1 and L3 measurements on the network device. Of course, the contents included in the above-mentioned first channel set and first on-demand set can also be expanded as needed.

[0086] In one embodiment of this application, the first signal may be an uplink wake-up signal (Signal UL-WUS). The configuration information of the first signal includes one or more of the following:

[0087] The time-domain information of the first signal is used to indicate the transmission time-domain information of the first signal (e.g., the time-domain start position of the first signal resource pool), or to indicate the time-domain offset information between the transmission time-domain position of the first signal and the time-domain position of the first target signal or channel, which may be represented by the number of time slots and / or the number of symbols.

[0088] The frequency domain information of the first signal is used to indicate the frequency domain information of the first signal transmission (e.g., the frequency domain start position of the first signal resource pool), or to indicate the frequency domain offset information between the transmission frequency domain position of the first signal and the frequency domain position of the first target signal or channel, which may be represented by, for example, the number of resource blocks and / or subcarriers.

[0089] The subcarrier spacing information of the first signal is used to determine the subcarrier spacing of the first signal. For example, the terminal can determine the subcarrier spacing of the first signal based on this information and the information of FR1 or FR2 of the frequency point where the first SSB set is located.

[0090] The first signal sequence index number information is used to indicate the sequence information adopted by the first signal, such as the first sequence, the second sequence, etc. Different sequences can indicate the transmission of different second target signals or channels;

[0091] Information used to calculate the transmission power of the first signal, such as the transmission power of network devices (e.g., base stations, Pcells), power ramp-up step values, etc., allows the terminal to calculate the transmission power of the first signal, path loss between the terminal and network devices, etc.

[0092] At least one piece of information included in the configuration information of the first signal can be indicated by a field, wherein each field occupies at least one bit. In this embodiment, the specific type of field used is not limited. Alternatively, the at least one piece of information can be indicated by a first signal configuration index number, whereby the configuration information of the first signal is determined based on the first signal configuration index number and a first correspondence relationship, whereby the first correspondence relationship is the relationship between the first signal configuration index number and the configuration information of the first signal. For example, the first correspondence relationship can be a mapping table, whereby the terminal obtains the configuration information of the first signal corresponding to the first signal configuration index number by looking up the mapping table. Alternatively, a combination of the above two methods can be used to indicate the information; for example, a portion of the information can be indicated by a field, and the remaining information can be indicated by the first signal configuration index number.

[0093] The configuration information for the first signal is predefined or preconfigured, including the time-frequency resources and sequence parameters used by the first signal being predefined or preconfigured; that is, at least one of the aforementioned information items is predefined or preconfigured. In this case, the terminal can randomly select at least one piece of configuration information for the first signal from the candidate set of configuration information for the first signal, or, based on the terminal's identifier, select at least one piece of configuration information for the first signal from the candidate set of configuration information for the first signal. The candidate set of configuration information for the first signal includes multiple instances of the aforementioned at least one piece of information and can exist in the form of a configuration resource pool.

[0094] For example, the terminal can calculate (e.g., modulo) its UE ID and, based on the calculation result, select at least one piece of configuration information for the first signal from the candidate set of configuration information for the first signal. For example, the terminal can randomly select time-frequency resources, parameters, etc., occupied by the first signal from the configuration resource pool of the first signal.

[0095] In this embodiment, if the first target signal or channel is a first SSB, and the second target signal or channel is a second SSB or a first on-demand set, then the PBCH type in the first SSB set is different from the PBCH type in the second SSB set, and / or, the PBCH type in the first SSB set is different from the PBCH type in the first on-demand set. Alternatively, the information carried by the PBCH in the first SSB set is different from the information carried by the PBCH in the second SSB set, and / or, the information carried by the PBCH in the first SSB set is different from the information carried by the PBCH in the first on-demand set.

[0096] For example, PBCH type 0 in the first SSB set is used to carry configuration information for the first signal, but not initial access information. Since the configuration information for the first signal is limited, PBCH type 0 is suitable for carrying it, and its payload is less than 10 bits. PBCH type 1 in the second SSB set or the first on-demand set is used to carry the Master Information Block (MIB) for initial access, and its payload is larger, for example, 32 bits. The SS in the second SSB set is also used to indicate the Physical Cell Identifier (PCI) information of the network device.

[0097] In this embodiment of the application, if the first target signal or channel is the first channel set, namely PDICH, the payload of PDICH is small (e.g., less than 10 bits), and only carries the configuration information of the first signal. The initial access information, etc., are carried through the second target signal or channel.

[0098] If the first target signal or channel is a first set of SS signals, then each SS in the first set of SS signals includes: a primary synchronization signal (PSS) and a secondary synchronization signal (SSS); or, each SS in the first set of SS signals includes one synchronization signal. In this case, the terminal can obtain the configuration information of the first signal through at least one of the following methods:

[0099] (1) Obtain the configuration information of the first signal indicated by the sequence of PSS and / or the sequence of SSS, wherein different sequences correspond to different first signal configuration index numbers. Based on the first correspondence and the first signal configuration index number, the terminal can determine the configuration information of the first signal. The first correspondence is the correspondence between the first signal configuration index number and the configuration information of the first signal.

[0100] (2) The first signal configuration index number is determined by the Orthogonal Frequency Division Multiplexing (OFDM) symbol positions occupied by the PSS and / or the OFDM symbol positions occupied by the SSS. That is, different OFDM symbol positions occupied by the PSS and / or the SSS can indicate different first signal configuration index numbers. Based on the first correspondence and the first signal configuration index number, the terminal can determine the configuration information of the first signal.

[0101] (3) The first signal configuration index number is determined by the order between the OFDM symbol positions occupied by the PSS and the OFDM symbol positions occupied by the SSS. Different orders correspond to different first signal configuration index numbers. For example, if the OFDM symbol position occupied by the PSS precedes the OFDM symbol position occupied by the SSS, there is a corresponding first signal configuration index number; if the OFDM symbol position occupied by the PSS follows the OFDM symbol position occupied by the SSS, there is a different first signal configuration index number. These two first configuration index numbers are different. Therefore, based on the first correspondence and the first signal configuration index number, the terminal can determine the configuration information of the first signal.

[0102] (4) Determine the configuration information of the first signal through the sequence of SS.

[0103] Among them, different SS sequences correspond to different first signal configuration index numbers. Based on the first correspondence and the first signal configuration index number, the terminal can determine the configuration information of the first signal.

[0104] As mentioned above, the first signal can be an uplink wake-up signal. In the embodiments of this application, different forms of the first signal can be used. For example, the first signal can be a first preamble, which is only used to trigger the transmission of the second target signal or channel. Alternatively, the first signal can also be a new signal used only to trigger the transmission of the second target signal or channel, such as a binary on-off keying (OOK) signal, a binary phase shift keying (BPSK) signal, a frequency-shift keying (FSK) signal, or a minimum shift keying (MSK) signal.

[0105] In this embodiment, the configuration information of the first signal includes a first signal sequence index number, used to indicate the sequence used by the first signal. That is, the terminal can determine, based on this configuration information and service requirements, which form of sequence to use to indicate the transmission of the second target signal or channel. Different forms of sequences can be used to indicate different second target signals or channels. In practical applications, the sequence used by the first signal includes one or more of the following:

[0106] The first signal uses a first sequence to trigger the network device to send a second set of SSBs;

[0107] The first signal uses a second sequence to trigger the network device to send a second SS set;

[0108] The first signal uses a third sequence to trigger the network device to send one set from the first on-demand set. For example, the set can be any set.

[0109] The first signal adopts a fourth sequence to trigger the network device to send at least two types of information, channels, or signals from the second SSB set, the second SS set, and the first on-demand set. For example, the at least two types of information, channels, or signals can be randomly selected information, channels, or signals.

[0110] The first signal employs a fifth sequence to trigger the network device to send at least two types of information, signals, or channels from the first on-demand set. For example, the at least two types of information, channels, or signals may be randomly selected information, channels, or signals.

[0111] By having the terminal use different sequences of first signals to indicate the type of on-demand set to be triggered to the base station, the base station can know which type of on-demand set the terminal wants to trigger, which helps the terminal to select and trigger the appropriate on-demand set type.

[0112] To avoid mutual interference caused by time-domain overlap between first signals transmitted by different terminals, the first signal includes: a cyclic prefix (CP), the sequence used by the first signal, and a guard time (GT). For example, the CP is located before the sequence used by the first signal, and the GT is located after the sequence used by the first signal.

[0113] The choice of which signal or channel triggers the network device to send the second target signal or channel can be determined by the terminal or the network device. If the terminal determines the choice, it can trigger the network device to send which signal or channel based on service requirements. If the network device determines the choice, it can indicate at least one of the supported signals or channels of the second target signal or channel based on at least one of the following:

[0114] (1) The sequence of PSS and / or the sequence of SSS in the first SS set: The sequence of different PSS and / or the sequence of SSS may indicate at least one of the second target signals or channels that support transmission.

[0115] (2) OFDM symbol positions occupied by PSS and / or OFDM symbol positions occupied by SSS: Different OFDM symbol positions occupied by PSS and / or different OFDM symbol positions occupied by SSS may indicate at least one of the second target signals or channels that support transmission.

[0116] (3) The order between the OFDM symbol position occupied by PSS and the OFDM symbol position occupied by SSS: For example, if the OFDM symbol position occupied by PSS is before the OFDM symbol position occupied by SSS, there is a signal or channel among the second target signal or channel that can be transmitted; if the OFDM symbol position occupied by PSS is after the OFDM symbol position occupied by SSS, there is a signal or channel among the second target signal or channel that can be transmitted.

[0117] (4) The sequence of SS in the first SS set: different SS sequences correspond to different signals or channels in the second target signal or channel that support transmission.

[0118] (5) The first SS set, that is, when the terminal determines that the received first target signal or channel is from the first SS set, it can determine at least one of the second target signals or channels that the network device supports transmitting. This correspondence can be pre-configured or pre-defined.

[0119] According to the instructions of the aforementioned network devices, the terminal can trigger the network devices to send corresponding signals or channels.

[0120] In this embodiment, the timing of transmitting the first signal can be determined by the terminal based on its own needs, or it can be determined based on the first target signal or channel. If the first target signal or channel includes a first set of SSBs, the terminal can determine the first transmission timing of the first signal (UL-WUS Occasion, UO) based on the index number of the first SSB in the first SSB set. The first SSB can be any SSB; that is, the transmission timing of the first signal is bound to the index number of the SSB in the first SSB set. Different SSBs can correspond to different first transmission timings. Once the corresponding transmission timing is determined, the terminal can transmit the first signal according to that timing.

[0121] Alternatively, the terminal can send the first signal according to a second transmission timing, wherein the first signal is used to trigger the network device to send a second SSB from the second SSB set, and the second transmission timing corresponds to the index number of the second SSB. For example, this correspondence can be a one-to-one correspondence, that is, one transmission timing corresponds to one index number of the second SSB. Then, the network device can determine the SSB with the corresponding index number according to the second timing and send the SSB with the corresponding index number, thereby reducing the number of SSBs sent by the network device. Of course, this correspondence can also be in other forms, as long as the network device can determine the SSB in the second SSB set that needs to be sent according to the correspondence.

[0122] Different terminals attempt to use different time-frequency resources for their first signals, thus minimizing the risk of collisions. However, if different terminals send the same first signal, even if a collision occurs, it will not affect the network device's reception of the first signal. If different terminals send the same first signal, it is equivalent to the network device receiving diversity-transmitted first signals from different terminals.

[0123] In this embodiment, the terminal acquires configuration information of a first signal and sends the first signal according to the configuration information. The first signal triggers the transmission or reception of a second target signal or channel. Since the terminal acquires configuration information of the first signal, it can acquire the configuration information and send the first signal over a longer period. This allows the network device more time to enter a deep sleep state when it does not receive the first signal sent by the terminal, thus achieving energy saving. At the same time, since the second target signal or channel is triggered by the terminal to send or receive, the terminal's access latency can also be reduced.

[0124] See Figure 2 , Figure 2 This is a flowchart of an information processing method provided in an embodiment of this application, applied to a network device, such as... Figure 2As shown, it includes the following steps:

[0125] Step 201: Configure or send configuration information of the first signal to the terminal;

[0126] Step 202: Receive the first signal sent by the terminal;

[0127] The methods for configuring or sending configuration information of the first signal to the terminal include one or more of the following:

[0128] Send a first target signal or channel, the first target signal or channel being used to indicate configuration information of the first signal; a predefined method; a preconfigured method;

[0129] The first signal is used to trigger the network device to send or receive a second target signal or channel, the second target signal or channel being used for at least one of cell search, initial access, random access, and paging.

[0130] In this embodiment, the terminal acquires configuration information of a first signal and sends the first signal according to the configuration information. The first signal triggers the transmission or reception of a second target signal or channel. Since the terminal acquires configuration information of the first signal, it can acquire the configuration information and send the first signal over a longer period. This allows the network device more time to enter a deep sleep state when it does not receive the first signal sent by the terminal, thus achieving energy saving. At the same time, since the second target signal or channel is triggered by the terminal to send or receive, the terminal's access latency can also be reduced.

[0131] The configuration information of the first signal, the first target signal or channel, the second target signal or channel, and the explanation of the first signal can be referred to the description of the foregoing method embodiments.

[0132] In this embodiment of the application, the network device may send the configuration information of the first signal in at least one of the following ways:

[0133] (1) Through the sequence of PSS and / or the sequence of SSS, wherein different sequences correspond to different first signal configuration index numbers, the terminal can determine the configuration information of the first signal according to the first correspondence and the first signal configuration index number, wherein the first correspondence is the correspondence between the first signal configuration index number and the configuration information of the first signal.

[0134] (2) The first signal configuration index number is indicated by the OFDM symbol position occupied by the PSS and / or the OFDM symbol position occupied by the SSS: Different OFDM symbol positions occupied by the PSS and / or different OFDM symbol positions occupied by the SSS can indicate different first signal configuration index numbers. Based on the first correspondence and the first signal configuration index number, the terminal can determine the configuration information of the first signal.

[0135] (3) The first signal configuration index number is indicated by the order between the OFDM symbol positions occupied by the PSS and the OFDM symbol positions occupied by the SSS. For example, if the OFDM symbol position occupied by the PSS precedes the OFDM symbol position occupied by the SSS, there is a corresponding first signal configuration index number; if the OFDM symbol position occupied by the PSS follows the OFDM symbol position occupied by the SSS, there is also a corresponding first signal configuration index number. These two first configuration index numbers are different. Therefore, based on the first correspondence and the first signal configuration index number, the terminal can determine the configuration information of the first signal.

[0136] (4) The configuration information of the first signal is transmitted through the sequence of SS. Different SS sequences correspond to different first signal configuration index numbers. Based on the first correspondence and the first signal configuration index number, the terminal can determine the configuration information of the first signal.

[0137] In this embodiment of the application, the network device can indicate to the terminal, through at least one of the following information, that the network device supports transmitting at least one of the second target signals or channels:

[0138] (1) The sequence of PSS and / or the sequence of SSS in the first SS set: The sequence of different PSS and / or the sequence of SSS may indicate at least one of the second target signals or channels that support transmission.

[0139] (2) OFDM symbol positions occupied by PSS and / or OFDM symbol positions occupied by SSS: Different OFDM symbol positions occupied by PSS and / or different OFDM symbol positions occupied by SSS may indicate at least one of the second target signals or channels that support transmission.

[0140] (3) The order between the OFDM symbol position occupied by PSS and the OFDM symbol position occupied by SSS: For example, if the OFDM symbol position occupied by PSS is before the OFDM symbol position occupied by SSS, there is a signal or channel among the second target signal or channel that can be transmitted; if the OFDM symbol position occupied by PSS is after the OFDM symbol position occupied by SSS, there is a signal or channel among the second target signal or channel that can be transmitted.

[0141] (4) The sequence of SS in the first SS set: different SS sequences correspond to different signals or channels in the second target signal or channel that support transmission.

[0142] (5) The first SS set, that is, when the terminal determines that the received first target signal or channel is the first SS set, it can determine at least one of the second target signals or channels that the network device supports sending.

[0143] The first signal employs one or more of the following sequences:

[0144] The first signal uses a first sequence to trigger the network device to send a second set of SSBs;

[0145] The first signal uses a second sequence to trigger the network device to send a second SS set;

[0146] The first signal uses a third sequence to trigger the network device to send one set from the first on-demand set. For example, the set can be any set.

[0147] The first signal adopts a fourth sequence to trigger the network device to send at least two types of information, channels, or signals from the second SSB set, the second SS set, and the first on-demand set. For example, the at least two types of information, channels, or signals can be randomly selected information, channels, or signals.

[0148] The first signal employs a fifth sequence to trigger the network device to send at least two types of information, signals, or channels from the first on-demand set. For example, the at least two types of information, channels, or signals may be randomly selected information, channels, or signals.

[0149] Accordingly, the network device can send a corresponding second target signal or channel based on the sequence adopted by the first signal.

[0150] In this embodiment, the network device can receive the first signal sent by the terminal according to a second transmission timing. The first signal is used to trigger the network device to send a second SSB from a second SSB set. The second transmission timing corresponds to the index number of the second SSB. For example, this correspondence can be a one-to-one correspondence, that is, one transmission timing corresponds to one index number of a second SSB. Then, the network device can determine the SSB with the corresponding index number according to the second timing and send the SSB with the corresponding index number, thereby reducing the number of SSBs sent by the network device. Of course, this correspondence can also be in other forms, as long as the network device can determine the SSB in the second SSB set that needs to be sent according to the correspondence.

[0151] The implementation process of the embodiments of this application is described below with reference to different examples. A base station is used as an example of a network device. It is understood that the various embodiments are also applicable to PCell.

[0152] In related technologies, to reduce base station energy consumption, base stations use larger period values ​​(such as 80ms or 160ms) to send the SSB set used to provide initial access information to the terminal. However, when decoding the PBCH in the SSB, the terminal often needs to receive multiple SSBs to decode successfully (performance evaluation shows that the terminal needs to receive 3 SSBs to guarantee a PBCH decoding success rate of over 80%). If a long period SSB of 80ms is used, the terminal can take up to 240ms to complete the decoding of 3 SSBs, resulting in a longer initial access delay.

[0153] Therefore, in this embodiment, before sending a set of signals or channels for providing initial access information to the terminal, the base station first sends a first target signal or channel for providing configuration information of the first signal (i.e., uplink wake-up information configuration information). Since the configuration information of the first signal occupies fewer bits, the terminal only needs to receive it once to successfully decode it. Then, the terminal sends the first signal (uplink wake-up signal) to trigger the on-demand transmission of the second target signal or channel, and performs at least one of cell search, initial access, random access, and paging according to the instructions in the second target signal or channel.

[0154] In one embodiment of this application, the base station transmits at least one signal or channel from a periodic first SSB set (AO-SSB), a first SS set (AO-SS), and a first channel set, or uses at least one predefined or preconfigured method, or a combination of the above methods, to indicate configuration information of a first signal to the terminal. The terminal performs downlink coarse synchronization and obtains the configuration information of the first signal based on at least one of the first SSB set, the first SS set, and the first channel set, or based on predefined or preconfigured information, or a combination of the above methods. The terminal transmits the first signal, triggering the base station to transmit at least one signal or channel from an on-demand second SSB set (OD-SSB), a second SS set (OD-SS), and a first on-demand set. The first terminal measures at least one of the second SSB set (OD-SSB), the second SS set (OD-SS), and the first on-demand set to complete downlink synchronization.

[0155] Specifically, the base station sends at least one set of a sparse, periodic first SSB set (Always-On SSB) or a first SS set, or uses at least one predefined, preconfigured method, or a combination of the above methods. The terminal performs downlink coarse synchronization and obtains configuration information for a first signal based on the first SSB set or the first SS set, or based on predefined or preconfigured information, or a combination of the above methods. The first signal is an uplink wake-up signal used to trigger at least one set of a second SSB set, a second SS set, and a first on-demand PBCH. The first SSB set contains {4, 8, 64} SSBs, each with a different SSB index number. Then, the terminal sends the first signal, triggering the base station to send at least one set of an on-demand second SSB set, a second SS set, and a first on-demand PBCH.

[0156] The application scenarios of this application include:

[0157] Application Scenario 1: For idle terminals, the second SSB set or the first on-demand set is used for initial terminal access. Application Scenario 2: For connected terminals, the second SSB set or the second SS set assists the terminal in maintaining time-frequency synchronization and performing L1 / L3 measurements at the base station.

[0158] like Figure 3 The diagram shown is a transmission illustration of an embodiment of this application, wherein the base station transmits a sparse, periodic first SSB set and a dense second SSB set triggered by the terminal; as shown... Figure 4 The diagram shown is a transmission schematic of an embodiment of this application, in which the base station transmits a sparse periodic first SS set and a dense first on-demand set triggered by the terminal.

[0159] Here, sparse means a larger transmission period, for example, for the transmission of the first target signal or channel, the period value can be 80ms, 160ms, etc.; dense means a smaller transmission period, such as 5ms, etc.

[0160] exist Figure 3 In this process, the base station first sends a first SSB set, indicating the configuration information for the first signal. When a terminal needs to send a service, it can use this configuration information to send the first signal, triggering the transmission of a second SSB set. The base station then sends the second SSB set, and the terminal uses it to complete downlink synchronization and initial access. This allows the base station more time to enter a deep sleep state when no terminal is sending the first signal, achieving energy saving. Figure 4In this process, the base station first sends a first SS set, indicating the configuration information of the first signal. Thus, when a terminal needs to send a service, it can send the first signal based on this configuration information, triggering the first on-demand set. The base station sends the first on-demand set, and the terminal completes downlink synchronization and initial access based on it. In this way, when no terminal is sending the first signal, the base station has more time to enter a deep sleep state, achieving energy saving.

[0161] In this embodiment, the base station transmits AO-SSB or AO-SS to provide first signal configuration information at a period of 80ms or 160ms, or uses at least one of predefined and pre-configured methods, or a combination of the above methods, to indicate the configuration information of the first signal to the terminal. The terminal sends the first signal, triggering the base station to send OD-SSB. The first terminal measures the OD-SSB and completes downlink synchronization. Thus, by increasing the periodic value of AO-SSB and AO-SS, the base station's energy consumption is reduced; and the on-demand transmission of OD-SSB triggered by the terminal also reduces terminal access latency.

[0162] Regarding the first signal sent by the terminal, its format includes two possible methods:

[0163] Method 1: Enhance the existing preamble format, that is: introduce a new preamble format as the first signal, which is specifically used to trigger the base station to send at least one of the following sets: the second SSB set, the second SS set, and the first on-demand set.

[0164] Method 2: Design a new first signal that is only used to trigger the base station to send at least one of the following sets: second SSB set, second SS set, and first on-demand set. It may be a signal that is simpler than the preamble, such as: OOK signal, BPSK signal, FSK signal, MSK signal, etc.

[0165] like Figure 5 As shown, the terminal uses different sequences of first signals to indicate the type of on-demand set to be triggered to the base station, including:

[0166] The first signal uses a first sequence: indicating that the terminal triggers the second SSB set; for example, the first sequence is the first OOK sequence {0,1,0,1,0,1}.

[0167] The first signal uses the second sequence: indicating that the terminal triggers the second SS set; for example, the first sequence is the second OOK sequence {1,0,1,0,1,0}.

[0168] The first signal uses a third sequence: indicating that the terminal triggers one of the sets in the first on-demand set; for example, the first sequence is the third OOK sequence {0,0,1,0,0,1}.

[0169] The first signal uses a fourth sequence: indicating that the terminal triggers at least two types of information, channels, or signals from the second SSB set, the second SS set, and the first on-demand set; for example, the first sequence is the fourth OOK sequence {1,0,1,1,0,1}.

[0170] The first signal adopts the fifth sequence: indicating that the terminal triggers the network device to send at least two types of information, signals or channels from the first on-demand set; for example, the first sequence is the fifth OOK sequence {1,0,1,1,1,1}.

[0171] By having the terminal use different sequences of first signals to indicate the type of on-demand set to be triggered to the base station, the base station can know which type of on-demand set the terminal wants to trigger, which helps the terminal to select and trigger the appropriate on-demand set type.

[0172] In one embodiment of this application, the base station transmits a periodic first SSB set (AO-SSB) to indicate the configuration information of the first signal to the terminal. The terminal performs downlink coarse synchronization and obtains the configuration information of the first signal based on the first SSB set. The terminal transmits the first signal, triggering the base station to transmit a second SSB set (OD-SSB) on demand. The first terminal measures the second SSB set (OD-SSB) to complete downlink synchronization.

[0173] Specifically, the PBCH type in the first SSB set is different from the PBCH type in the second SSB set, or the information carried by the PBCH in the first SSB set is different from the information carried by the PBCH in the second SSB set. For example, PBCH type 0 in the first SSB set has a smaller payload, indicating only the configuration information of the first signal and not the initial access information. The configuration information of the first signal is relatively small, suitable for PBCH type 0 indication, with a payload of less than 10 bits, such as 8 bits. This is equivalent to 1 / 4 of the 32-bit PBCH payload of 5G New Radio (NR). With the time-frequency resources and modulation and coding scheme (MCS) occupied by the PBCH unchanged, the PBCH detection success rate is greatly improved. The terminal only needs to detect one first SSB set to complete the correct decoding of PBCH type 0. PBCH type 1 in the second SSB set is used to indicate the MIB information of the initial access, with a larger payload, such as 32 bits.

[0174] The meaning of the configuration signal of the first signal can be referred to the description of the aforementioned method embodiments.

[0175] The methods by which a base station indicates the configuration information of the first signal may include the following:

[0176] (1) At least one piece of information of the configuration signal of the first signal is indicated by a separate field, each field occupying at least one bit.

[0177] (2) At least one piece of information of the configuration signal of the first signal is indicated by the first signal configuration index number. The terminal obtains the specific configuration information by looking up the first signal configuration index number and a predefined mapping table between the first signal configuration index number and the specific configuration information.

[0178] If all configuration information of the first signal is predefined, including the time-frequency resources and sequence parameters used by the first signal, then when the terminal selects the time-frequency resources of the first signal from the candidate time-frequency positions, it can use a random selection method or a Mod (UE ID) method to select the time-frequency resources and various parameters occupied by the first signal from the first signal resource pool.

[0179] by Figure 6 For example, the base station first sends a first SSB set, indicating the configuration information of the first signal. PBCH type0 in the first SSB set indicates the time-domain and frequency-domain information of the first signal, namely: Figure 6 The first signal resource pool in the configuration contains time-domain offset information and frequency-domain offset information relative to the first SSB set. When a terminal needs to send a service, it can obtain the time-frequency position of the first signal resource pool based on the configuration information of the first signal, and then select a candidate resource from the first signal resource pool (i.e., Figure 6 The base station sends a first signal to the candidate resource 4 pointed to by 61, triggering the second SSB set. The base station sends the second SSB set, and the terminal completes downlink synchronization and initial access based on the second SSB set. In this way, when no terminal sends the first signal, the base station will have more time to enter a deep sleep state, achieving energy saving.

[0180] Two types of SSBs or PBCHs are defined. PBCH type 0 indicates the configuration information of the first signal and has a smaller payload, while PBCH type 1 indicates the initial access information and has a larger payload. Thus, the terminal can obtain the configuration information of the first signal by receiving a first set of SSBs, and then obtain the initial access information through a second set of SSBs. This helps to reduce both base station energy consumption and terminal access latency.

[0181] In one embodiment of this application, the base station transmits a periodic first channel set to indicate configuration information of a first signal to the terminal. The terminal performs downlink coarse synchronization and obtains the configuration information of the first signal based on the first channel set. The terminal transmits the first signal, triggering the base station to transmit a second SSB set (OD-SSB) on demand. The first terminal measures the second SSB set (OD-SSB) to complete downlink synchronization.

[0182] Specifically, the first channel set is PDICH, which indicates the first signal configuration information to the terminal. The PDICH payload is small, indicating only the configuration information of the first signal and not the initial access information. The PDICH payload is less than 10 bits, for example, 8 bits, which is equivalent to 1 / 4 of the 32-bit PBCH payload of 5G NR. With the time-frequency resources and MCS remaining unchanged, the detection success rate of PDICH is significantly improved. The terminal only needs to detect one first channel set to complete the correct decoding of PDICH. The meaning and indication method of the configuration information of the first signal can be referred to the description in the foregoing embodiments.

[0183] by Figure 7 For example, the base station first sends a first channel set, indicating the configuration information of the first signal. The PDICH in the first SSB set indicates the time-domain and frequency-domain information of the first signal, namely: Figure 7 The base station provides time-domain and frequency-domain offset information for the first signal resource pool relative to the first SSB set. When a terminal needs to transmit a service, it can use this configuration information to obtain the time-frequency location of the first signal resource pool, select a candidate resource from the pool, and transmit the first signal, triggering the second SSB set. The base station then transmits the second SSB set, and the terminal completes downlink synchronization and initial access based on it. This allows the base station more time to enter deep sleep mode when no terminal is transmitting the first signal, achieving energy saving.

[0184] In this embodiment, the first channel PDICH indicates the configuration information of the first signal and has a smaller payload, while the original PBCH indicates the initial access information and has a larger payload. Therefore, the terminal can obtain the first signal configuration information by receiving one set of first channels, and then obtain the initial access information through the second set of SSBs. This helps to reduce both base station energy consumption and terminal access latency.

[0185] In one embodiment of this application, the base station sends a periodic first SS set (AO-SS) to indicate the configuration information of the first signal to the terminal. The terminal performs downlink coarse synchronization and obtains the configuration information of the first signal based on the first SS set. The terminal sends the first signal, triggering the base station to send an on-demand first on-demand set. The first terminal measures the first on-demand set and completes downlink synchronization.

[0186] Specifically, the base station sends the first SS set, also known as the AO-SS set, to indicate the first signal configuration information to the terminal. The payload of the first SS set is relatively small, indicating only the configuration information of the first signal and not the initial access information.

[0187] Each SS in the first SS set consists of two synchronization signals, including PSS and SSS, or each SS in the first SS set consists of one synchronization signal. The PSS or SSS or SS sequence in the first SS set contains multiple candidate sequences. Thus, the base station indicates the configuration information of the first signal through the PSS or SSS or SS sequence in the first SS set, and different sequences represent different configuration index numbers of the first signal.

[0188] As shown in Figure 8(a), the first sequence indicates that the first signal configuration index number is 1, the second sequence indicates that the first signal configuration index number is 2, and the third sequence indicates that the first signal configuration index number is 3.

[0189] The base station can also indicate the first signal configuration index number by the different OFDM symbol positions and / or order in which the PSS or SSS occupies the first SS set. As shown in Figure 8(b), if the terminal detects the transmission of an OFDM symbol before the SSS by the PSS, it indicates that the first signal configuration index number is 1; if the terminal detects the transmission of an OFDM symbol after the SSS by the PSS, it indicates that the first signal configuration index number is 2; if the terminal detects the transmission of an OFDM symbol between two SSSs (for example: the SSS occupies OFDM symbols 1# and 3#, and the PSS occupies OFDM symbol 2#), it indicates that the first signal configuration index number is 3.

[0190] In addition, the on-demand set types supported by the base station (second SSB set / second SS set / first on-demand set) can also be indicated by the first SS set, through the sequence of PSS, SSS, or SS in the first SS set, or by the different OFDM symbol positions and / or order occupied by PSS or SSS in the first SS set. Thus, after the terminal learns the on-demand set types supported by the base station, it can trigger the corresponding on-demand set through the first signal. The base station's PCI information is indicated by the SS in the subsequently transmitted second SSB set.

[0191] In this way, when a terminal needs to send a service, it can obtain the time-frequency location of the first signal resource pool based on this configuration information, then select a candidate resource from the first signal resource pool, send the first signal, and trigger the first on-demand set. The first on-demand set can be an OD-PBCH set. The base station sends the first on-demand set, and the terminal completes downlink synchronization and initial access based on the first on-demand set. Thus, when no terminal is sending the first signal, the base station has more time to enter a deep sleep state, achieving energy saving.

[0192] In this embodiment, the base station indicates the first signal configuration information to the terminal via AO-SS. The terminal can obtain the first signal configuration information by receiving a first SS set, and then obtain the initial access information through the first on-demand set. This helps to reduce both the base station's energy consumption and the terminal's access latency.

[0193] In this embodiment, multiple terminals may simultaneously transmit the first signal. To minimize collisions, the first signals from different terminals occupy different time-frequency resources. For example, as shown in Figure 9(a), terminal A uses candidate resource 2 (pointed to 92) to transmit the first signal, while terminal B uses candidate resource 4 (pointed to 91) to transmit the first signal. This prevents overlap between the candidate resources used by terminals A and B. Alternatively, different terminals may transmit the same time-frequency resource; even if a collision occurs, it will not affect the reception of the first signal. If different terminals transmit the same first signal, it is equivalent to the base station receiving diversity-transmitted first signals from different terminals. As shown in Figure 9(b), both terminal A and terminal B occupy candidate resource 2 pointed to by 901 to send the first signal. Although the candidate resources occupied by terminal A and terminal B overlap, since the first signals sent by terminal A and terminal B are exactly the same, the first signal received by the base station is equivalent to the first signal sent by diversity. The base station only needs to merge the first signals sent by terminal A and terminal B, which will not affect the successful reception of the first signal.

[0194] In this embodiment of the application, the sequence of the first signal sent by the terminal is preceded by a CP (Cyclic Prefix) and followed by a GT (Guard Time) to prevent mutual interference caused by time domain overlap of the first signals sent by different terminals.

[0195] Furthermore, the timing of the first signal transmission is bound to the SSB index number of the first SSB set. When the terminal transmits the first signal in the appropriate UO, the base station will transmit an SSB beam with the corresponding index number (the index number corresponding to the UO), thereby reducing the number of SSB beams transmitted by the base station.

[0196] In this embodiment, the first signals sent by different terminals can occupy different time-frequency resources or occupy the same time-frequency resources. If different terminals send different first signals, they occupy different time-frequency resources, thus minimizing collisions between the first signals sent by different terminals. If different terminals send the same first signal, the first signals sent by different terminals can occupy the same time-frequency resources. This method can better utilize the candidate resources for first signals, allowing more terminals to reuse them within the candidate resources.
