[0040] In embodiments of the present application, a network device can serve a cell, and a terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource, or a spectrum resource) used by the cell. The cell can be a cell corresponding to the network device (for example, a base station), and the cell can belong to a macro base station or a base station corresponding to a small cell.

[0041] By way of example, FIG. 1 is a schematic diagram of an architecture of a communication system provided in embodiments of the present application. As shown in FIG. 1, the communication system 100 can include a network device 110, which can be a device that communicates with a terminal device 120 (or a communication terminal, a terminal). The network device 110 can provide communication coverage for a specific geographic area, and can communicate with terminal devices located within the coverage area.

[0042] FIG. 1 exemplarily shows one network device and two terminal devices. In some embodiments of the present application, the communication system 100 can include multiple network devices, and each network device can include other numbers of terminal devices within its coverage, which is not limited.

[0043] In embodiments of the present application, the communication system shown in FIG. 1 can also include a mobility management entity (MME), an access and mobility management function (AMF), and other network entities, which are not limited in embodiments of the present application.

[0044] It should be understood that the devices with communication functions in the network / system in the embodiments of the present application can be referred to as communication devices. For example, the communication system 100 shown in FIG. 1 can include network devices 110 and terminal devices 120 with communication functions, which can be specific devices as described above, and details are not described herein again. The communication devices can also include other devices in the communication system 100, such as network controllers, mobile management entities, and other network entities, which are not limited in the embodiments of the present application.

[0045] For ease of understanding, some related technical knowledge involved in the embodiments of the present application is introduced first. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional schemes, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0046] With the development of mobile communication technology, a new generation of wireless evolution system (for example, a 5G system) improves the transmission rate of data through multiple technologies to meet the transmission demand of large data volume such as high-definition video and virtual reality. Multiple technologies such as multiple-input multiple-output (MIMO) technology, non-orthogonal multiple access technology, simultaneous same frequency full duplex communication technology, new modulation technology, new coding technology, and high-order modulation technology. Through these technologies, the peak rate can reach Gbit / s.

[0047] As an example, the delay level of the air interface needs to be around 1ms to meet the real-time application of automatic driving, remote medical treatment, etc.

[0048] As an example, the super large network capacity can provide the connection ability of hundreds of billions of devices to meet the communication demand of the Internet of Things.

[0049] As an example, the spectral efficiency of the NR system is more than 10 times higher than that of the LTE system. Based on continuous wide area coverage and high mobility, the user's experience rate can reach 100 Mbit / s. Therefore, the traffic density and the connection number density are greatly improved.

[0050] In addition, the improvement of system coordination and intelligence level further improves the flexibility of the network. System coordination can be manifested as the coordinated networking of multiple users, multiple points, multiple antennas, and multiple cameras. Based on coordination and intelligence, the network can be automatically adjusted flexibly between networks.

[0051] However, in the communication system, the power consumption of the network device (for example, the base station device) is usually relatively high. In order to save the power consumption of the base station device, the system message needs to be optimized. For ease of understanding, the system message of the NR is taken as an example for description.

[0052] The system information of the NR can be divided into a master information block (MIB) message and some SIB messages. The MIB message is usually transmitted on a broadcast channel (BCH). The transmission period of the MIB is 80 ms. The MIB can be repeatedly transmitted within the 80 ms period. In addition, the MIB message also includes parameters required by the terminal device to acquire the SIB1 message from the cell.

[0053] The SIB1 message can also be referred to as a SIB type 1 message. The SIB1 is transmitted on a downlink-shared channel (DL-SCH) with a period of 160 ms. Within 160 ms, the SIB can also be repeatedly transmitted with a variable transmission repetition period. The default transmission repetition period of the SIB1 is 20 ms, and the actual transmission repetition period depends on the network implementation. For example, for the multiplexing mode 1 of the synchronization signal block (SSB) and the control resource set (CORESET), the transmission repetition period of the SIB1 is 20 ms. For example, for the multiplexing mode 2 / 3 of the SSB and the CORESET, the transmission repetition period of the SIB1 is the same as the period of the SSB.

[0054] In the embodiments of the present application, the SSB can also represent a synchronization signal and PBCH block.

[0055] The SIB1 can carry the key information required by the terminal device to access the cell, such as random access parameters. The SIB1 also includes information related to the availability and scheduling of other SIBs, such as the mapping of other SIBs to system information (SI) messages, periodicity, SI window size, etc. The SIB1 can also indicate whether one or more SIBs are provided on demand only, in which case the SIB1 can also provide the physical random access channel (PRACH) configuration required by the terminal device to request the SI required by the terminal device. The SIB1 also contains radio resource configuration information common to all terminal devices and cell barring information applied to unified access control.

[0056] When the SIB1 includes information related to other SIBs, the other SIB messages can be provided by periodic broadcasting or on demand. If the other SIBs are provided on demand, the SIB1 can also include information for the terminal device to perform the SI request.

[0057] SIB messages other than SIB1 (other SIBs) can be included in SI messages. These messages can also be transmitted on the DL-SCH. Each SI message can be transmitted periodically within a time domain window, referred to as an SI window. Exemplarily, only SIBs with the same periodicity can be mapped to the same SI message. All SI messages can have the same length of SI window when each SI message is sent within a periodically occurring time domain window. Each SI message is associated with one SI window, and the SI windows of different SI messages do not overlap. That is, only the corresponding SI message is sent within one SI window. In addition, the system can send the SI message multiple times within the SI window.

[0058] The above introduces various SIB messages taking the system message of NR as an example. The network device (for example, gNB) can periodically send SIB1 for initial access, and schedule other SIBs of the terminal device in idle / inactive mode. Even if there is no demand from the terminal device, or there is no terminal device camping on the cell, the network device will always transmit. Therefore, in some scenarios, the periodic transmission of SIB1 by the network device can cause large energy waste.

[0059] In order to realize network energy saving, unnecessary SIB1 transmission and associated PRACH monitoring need to be reduced. Therefore, on-demand transmission of SIB1 for terminal devices in idle / inactive state becomes a research direction to provide more opportunities for the network device to sleep. Exemplarily, how to realize the on-demand transmission of SIB1 to save the energy of the network device is a technical difficulty worthy of research.

[0060] In some embodiments, the cell that transmits SIB1 on demand is referred to as an energy saving cell, for example, a network energy saving (NES) cell. For terminal devices in idle mode, since the NES cell does not carry SIB1 information when transmitting SSB, the terminal device needs to send related request information / signaling to request the NES cell to send SIB1 information.

[0061] Optionally, the request information of on-demand SIB1 can be an uplink wake up signal (WUS), or other on-demand information / signaling for requesting SIB1. The WUS is an uplink (UL) trigger for on-demand SIB1.

[0062] Optionally, the terminal device can send the request information triggering the on-demand SIB1 through a random access channel (RACH) or a separate signal or sequence. For example, the terminal device can send the WUS through the PRACH.

[0063] For ease of understanding, the transmission of the on-demand SIB1 is schematically described below by taking the WUS as an example in combination with FIG. 2. The terminal device 210 in FIG. 2 is in a cell A (Cell#A) in which the network device 220 provides services.

[0064] As shown in FIG. 2, the cell A always periodically sends an SSB without the SIB1, that is, the cell A is on-demand for the SIB1. When the terminal device attempts to access the cell A on-demand for the SIB1, the terminal device can send the WUS in the uplink to trigger the cell A to send the SIB1. When the cell detects the WUS or the on-demand request, the cell can send the on-demand SIB1 to the terminal device 210.

[0065] The above describes the method of sending the on-demand SIB1 based on the request information in combination with FIG. 2. When the terminal device sends the request information such as the WUS, the terminal device needs to obtain the time-frequency resource for the WUS so as to send the WUS in the idle state or the inactive state. However, how the terminal device in the idle state or the inactive state obtains the time-frequency resource for the request information such as the WUS is a problem to be considered.

[0066] For the time-frequency resource, the method of configuring the time-frequency resource based on the control resource set (CORESET) and the search space is described below by taking the NR system as an example. The CORESET mainly describes the frequency domain resource distribution, and the search space mainly describes the time domain resource distribution. Therefore, the pairing based on the CORESET and the search space can determine the specific time-frequency domain resource.

[0067] In the NR, the network side usually configures multiple CORESETs and search spaces in a bandwidth part (BWP). Through the pairing of the CORESET and the search space, one (block) or multiple time-frequency resources for different purposes can be determined.

[0068] Exemplarily, the CORESET and the search space can be one-to-one correspondence. For example, the time-frequency domain resources determined by one pair of CORESET and search space can be used to transmit the downlink control information (DCI) format 0_0 / 1_0 (i.e., DCI_format 0_0 / 1_0); and the time-frequency domain resources determined by another pair of CORESET and search space can be used to transmit the DCI_format 0_1 / 1_1.

[0069] Exemplarily, the CORESET and the search space can be one-to-many correspondence. For example, one CORESET can correspond to multiple search spaces.

[0070] Exemplarily, the search space 0 (Searchspace 0) is configured for the MIB. The time-frequency domain resources determined by the search space 0 in combination with the CORESET 0 can be used for the terminal device to receive the remaining minimum system information (RMSI).

[0071] Exemplarily, the network-side configured search space includes the common search space (CSS) and the UE specific search space (USS). The network-side configured search space and the CORESET associated therewith can be used to determine the time-frequency resource scheduling of the physical downlink control channel (PDCCH). Further, the PDCCH can be used to carry the scheduling information of the uplink or downlink data. The terminal device needs to periodically monitor the PDCCH to obtain the uplink or downlink data scheduling information. The monitoring period can be 1 slot.

[0072] As an example, the specific types and applications of the search space are shown in Table 1.

[0073] Table 1

[0074] As shown in Table 1, in the related art, five types of search spaces are mainly included in the CSS. Exemplarily, the search space of type 0 can be used to search for the SIB1; the search space of type 0A can be used to search for other system information (other system information, OSI) such as the SIB2; the search space of type 0B can be used to search for the SIB1; the search space of type 0C can be used to search for the SIB1; and the search space of type 1 can be used to search for the SIB1. The search space can be classified into different types, such as type 0, type 0A, type 1, type 2, and type 3. The type 0 search space can be used for searching for a message 1 (MSG1), a message 3 (MSG3), etc. The type 1 search space can be used for searching for a message 2 (MSG2), a message 4 (MSG4), etc. The type 2 search space can be used for searching for a paging message. The type 3 search space can be used for searching for a group common DCI.

[0075] Continuing to refer to Table 1, in the USS, the terminal device can detect whether the PDCCH has scheduling information. The downlink scheduling information can be physical downlink shared channel (PDSCH) resource scheduling information, and the uplink scheduling information can be physical uplink shared channel (PUSCH) resource scheduling information. For the downlink scheduling information, the terminal device can receive data through the PDSCH according to the scheduling information. For the uplink scheduling information, the terminal device can send data through the PUSCH according to the scheduling information. The PDCCH can also be used to carry uplink power control command words, time slot formats, etc. The PDCCH carrying different control information can be scrambled by different radio network temporary identifiers (RNTIs).

[0076] Exemplarily, for the USS, the base station can configure at least one search space set (SS set) for the terminal device. The terminal device can perform PDCCH monitoring based on the SS set. For example, the terminal device can perform PDCCH monitoring according to the parameters of the SS set.

[0077] Generally, the terminal device only knows that the PDCCH will be sent within the resource block (RB) range provided by the CORESET, but does not know which RBs are used. Therefore, the terminal device needs to further perform PDCCH blind detection on different search spaces or CORESETs, and only when the decoding is successful will the blind detection process stop. Exemplarily, the terminal device needs to search for PDCCH information according to different RNTI types. Exemplarily, the terminal device needs to continuously demodulate the PDCCH candidate set to obtain and determine the control channel element (CCE) index of each candidate PDCCH within the CORESET. The CCE index can be used to determine the starting position and the number of CCEs. The position of the specific CCE can also be determined by a search space function.

[0078] The method for a terminal device to determine system information or resource scheduling information through a search space is introduced above. When a network device transmits SIB1 on demand, SIB1 information does not need to be carried in the MIB. In this scenario, the configuration of the relevant search space is no longer applicable. For example, in an NES cell, the search space 0 or CORESET0 of the MIB can be changed to adapt to the transmission needs of the WUS.

[0079] In summary, since SIB1 is transmitted on demand, the WUS that triggers the transmission of SIB1 needs corresponding resource configuration information so that the terminal device knows which time-frequency resources to send the WUS on. Therefore, how to configure the time-frequency resources for the WUS becomes a technical problem that needs to be solved.

[0080] It should be noted that the above-mentioned problem of how the network device configures the time-frequency resources of the WUS is only an example, and the embodiments of the present application can be applied to the configuration of the time-frequency resources of any type of information / signaling that triggers the transmission of on-demand SIBs.

[0081] To solve the above problem, the embodiments of the present application propose a method for wireless communication. Through this method, a terminal device transmits a first request for requesting a first SIB on a first resource, and the configuration information of the first resource is carried in a master information block (MIB). As can be seen, the network device will set new configuration information in the MIB to indicate the first resource for transmitting the first request. After setting the configuration information of the first resource in the MIB, the terminal device can determine the time-frequency resource of the first request through the MIB to trigger the transmission of the first SIB of the energy-saving cell.

[0082] To facilitate understanding, the method proposed by the embodiments of the present application will be described in detail below in conjunction with FIG. 3. FIG. 3 is introduced from the perspective of the interaction between the terminal device and the network device.

[0083] The terminal device can be any type of terminal that can request on-demand SIBs, which is not limited here. In some embodiments, the terminal device can be in an idle state or an inactive state. For example, the terminal device can be a UE in an idle / inactive mode.

[0084] As an example, the terminal device is in an idle state. When the terminal device performs initial access to an NES cell, since the SSB transmitted by the NES cell does not include SIB1, the terminal device can request the network device serving the NES cell to transmit on-demand SIB1.

[0085] As an example, the terminal device is in an inactive state. When the terminal device resumes connection with an NES cell, the terminal device can wake up the NES cell and request the network device serving the NES cell to transmit on-demand SIB1.

[0086] In some embodiments, the terminal device can be a communication device supporting NES function. For example, in the case that the first SIB is not carried in the SSB or MIB, the terminal device can request the first SIB from the network device based on the NES function.

[0087] In some embodiments, the serving cell corresponding to the terminal device is an energy saving cell. For example, the cell where the terminal device is located is an NES cell. For example, in FIG. 2, the cell A is an NES cell, and the terminal device can be the terminal device 210 in the cell A.

[0088] As an example, the serving cell where the terminal device is located is an NTN cell, that is, the terminal device is a ground terminal in the NTN.

[0089] The network device can serve the cell where the terminal device is located. The network device can be any of the network devices described above, which is not limited here. For example, the network device can be any of the base stations described above.

[0090] In some embodiments, the network device can be a communication device supporting NES function. For example, the network device can increase the sleep time of the serving cell based on the NES function. For example, the network device can implement the energy saving configuration of the cell on-demand SIB1 transmission.

[0091] As an example, the network device can transmit a periodic SSB, and the SSB does not contain the configuration information of the SIB1. For example, the network device can be the network device 220 in FIG. 2.

[0092] As an example, the network device can transmit corresponding information or messages in different search spaces. For example, the network device indicates the resource information occupied by the CORESET0 and the search space 0 through the configuration parameter in the MIB. The MIB does not carry the information of the SIB1.

[0093] As an example, the network device can monitor the first request transmitted by the terminal device in time to respond. That is, even if the first cell is in sleep mode, the first request transmitted by the terminal device will be monitored.

[0094] As an example, the network device can receive the first request transmitted by the terminal device, which will be described below in connection with step S320.

[0095] As an example, the cell served by the network device is an NTN cell. For example, the network device can be a satellite covering the area where the terminal device is located in the NTN, or a ground gateway or a ground network device in communication with the satellite in the NTN.

[0096] In some embodiments, the terminal device and the network device can be relative. Illustratively, the relay device can also be referred to as a terminal device relative to the network device. Illustratively, the relay device can also be referred to as a network device relative to the terminal device.

[0097] Referring to FIG. 3, at step S310, the terminal device determines the configuration information of the first resource.

[0098] The first resource is used for the terminal device to send a first request for the first SIB. The network device triggers the sending of the first SIB based on the request of the terminal device, and therefore, the first SIB can also be referred to as an on-demand SIB. Details will be described later in combination with step S320.

[0099] Optionally, the first request can include the WUS described above, or can include uplink information or signaling similar to the function of the WUS.

[0100] The first resource can be a time-frequency domain resource of any size, which is not limited herein. In some embodiments, the first resource can include one or more time domain units. The time domain unit can be a symbol, a slot, or a time domain segment of other lengths. In some embodiments, the first resource can include one or more frequency domain units. The frequency domain unit can be a frequency segment of any length, such as a subcarrier.

[0101] The configuration information of the first resource can be used to indicate the first resource. Illustratively, the configuration information of the first resource can indicate the number of symbols occupied by the first resource, the starting symbol position, etc. Illustratively, the configuration information of the first resource can indicate the number of RBs occupied by the first resource.

[0102] The configuration information of the first resource can be carried in the MIB, so as to facilitate the terminal device in the idle state or the inactive state to determine the configuration information of the first resource in time. In some embodiments, the configuration information of the first resource is indicated by a configuration parameter in the MIB.

[0103] As an example, the configuration parameter in the MIB can be pdcch-ConfigSIB1. The MIB can multiplex the existing configuration parameter to indicate the configuration information of the first resource. For example, the terminal device can detect the configuration information of the first resource on the search space indicated by the parameter.

[0104] Exemplarily, the high four bits in the pdcch-ConfigSIB1 can represent a CORESET0 (controlResourceSetZero), which can be used to obtain a CORESET0 format, a frequency domain resource occupying symbol quantity, a RB quantity and a RB offset; and the low four bits can represent a search space 0, which can be used to obtain a system frame number (SFN) of the CORESET0, a slot index and a starting symbol, etc.

[0105] As an example, the configuration parameter in the MIB can be pdcch-ConfigWUS. Thus, the MIB can add a new configuration parameter to indicate the configuration information of the first resource. For example, the configuration information of the first resource is indicated by the pdcch-ConfigWUS. The terminal device can detect the configuration information of the first resource on the search space indicated by the parameter.

[0106] Exemplarily, the high four bits in the pdcch-ConfigWUS can represent a CORESET0, which can be used to obtain a CORESET0 format, a frequency domain resource occupying symbol quantity, a RB quantity and a RB offset. The low four bits in the pdcch-ConfigWUS can represent a search space 0, which can be used to obtain a SFN of the CORESET0, a slot index and a starting symbol, etc.

[0107] As a possible implementation manner, the time-frequency resource information of the WUS can be configured in the parameter pdcch-ConfigWUS.

[0108] In some embodiments, the configuration information of the first resource can be carried in the SSB sent by the network device.

[0109] In some embodiments, the configuration information of the first resource can be on the first search space. That is, the terminal device can detect the configuration information of the first resource on the first search space. Therefore, the first search space is a search space for the first request (WUS). As an example, the terminal device can detect a PDCCH on the first search space, so as to determine the configuration information of the first resource. That is, the configuration information of the first resource is indicated by the PDCCH on the first search space.

[0110] It should be understood that the detection of the terminal device on the search space can be represented as listening, monitoring or searching of the terminal device on the search space. The detection of the terminal device on the search space can include the PDCCH blind detection described above.

[0111] In some embodiments, the first search space can be any search space in a common search space (CSS) or a specific search space corresponding to the terminal device. Optionally, the specific search space corresponding to the terminal device belongs to the USS described above. The specific search space corresponding to the terminal device can also be referred to as the dedicated search space or the private search space of the terminal device.

[0112] Optionally, the search space corresponding to the WUS can be in the CSS or can be set in the private search space of the terminal device.

[0113] As an example, when the first search space is the CSS, the terminal device can detect or monitor in the CSS according to the configuration of the network device to determine the configuration information of the first resource. For example, the terminal device can determine the first search space from a plurality of search spaces according to the type of the first search space, and then detect the configuration information of the first resource in the first search space.

[0114] As an example, when the first search space is the specific search space corresponding to the terminal device, the network device can configure the related parameters of the specific search space. The related parameters can include the search space identity (ID), the monitoring period, the symbol position, etc.

[0115] As an example, in the specific search space of the terminal device, the network device or the terminal device can set the symbol position for monitoring the configuration information of the first resource in each time slot. For example, the symbol position for monitoring can be a plurality of consecutive symbols. For example, the symbol position for monitoring can be set according to odd and even symbols or according to a certain rule.

[0116] In some embodiments, the type of the first search space can be an existing search space type. For example, the type of the first search space can be the search space type mentioned in Table 1. Optionally, since the first resource is used to send the request information triggering the on-demand SIB1, the type of the first search space can be the search space for sending the SIB1 in Table 1. That is, in the NES cell, the first search space configured by the network side can replace the original search space of the SIB1.

[0117] As an example, the type of the first search space can be Type0-PDCCH CSS, i.e., Embodiment I.

[0118] As an example, when the search space corresponding to the first SIB is the second search space, the type of the search space corresponding to the first search space is the same as the type of the search space corresponding to the second search space. For example, the search space for the WUS and the search space for the SIB1 have the same type.

[0119] As an example, the first search space can directly adopt the search space configured by the network for SIB1. For example, the first search space can be used to send the configuration information of the first resource and / or the first SIB, and thus the first search space is the same as the second search space. In these scenarios, the first search space can also send SIB1 at the same time as sending the WUS, and the PDCCH is distinguished by different scrambling.

[0120] As an example, the network can periodically configure multiple search spaces including the first search space. The network can send the configuration information of the first resource in the first search space of the current period, and send the first SIB in the corresponding first search space of the next period.

[0121] As an example, when the first request is WUS, the PDCCH-configWUS can be indicated by PDCCH-configcommon: the search space for WUS replaces the search space of the original SIB1.

[0122] In some embodiments, the network can set a new search space for the resource of the first request. That is, the first search space for sending the first request is a newly set search space type, and there is no need to reuse the existing search space type. For example, the first search space for the first request belongs to a first type of search space, and the second search space for the first SIB belongs to a second type of search space, and the first type is different from the second type. Further, the first type of search space is a dedicated search space related to the first request.

[0123] As an example, the type to which the first search space belongs can be Type0B-PDCCH CSS, i.e. embodiment two.

[0124] As an example, after the terminal device sends the uplink WUS in the idle / inactive mode, the NTN can send the SIB1 information in the next period or the time specified by the protocol.

[0125] As an example, PDCCH-configcommon in MIB can indicate that the search space of the original SIB1 can be reserved for on-demand SIB1 (first SIB). In the case of supporting on-demand SIB1, the network device still sends the on-demand SIB1 through the MIB, and additionally sets a new search space Type0B-PDCCH CSS for supporting the resource configuration information of WUS.

[0126] The above introduces that the type of the first search space for the first request can be existing or newly set. The following takes WUS as an example to illustrate the two possible implementation manners in combination with Table 2.

[0127] Table 2

[0128] As shown in Table 2, in embodiment one, the type of the first search space for WUS is the existing search space type for SIB1, i.e. Type0-PDCCH CSS. Based on this embodiment, the network side can follow the existing search space setting mode, and only indicate in the configuration information whether the resource of the current period is used for sending the configuration information of the first resource or the information of SIB1. In embodiment two, the type of the first search space for WUS is newly set Type0B-PDCCH CSS. Based on this embodiment, the newly set search space can avoid conflict with the search space of WUS and the existing search space, and better meet the scenario of simultaneously sending on-demand SIB1 and WUS in one period.

[0129] In some embodiments, the first SIB can be configured on a specific search space corresponding to the terminal device, which can be determined by parameters in radio resource control (RRC). Illustratively, the network device can configure a dedicated search space for the terminal device. The terminal device can determine its dedicated search space according to the parameters in the RRC message.

[0130] As an example, when the first SIB is on a specific search space, the second search space can be one of a plurality of specific search spaces.

[0131] As an example, when the second search space is a specific search space corresponding to the terminal device, the network device can configure related parameters of the specific search space. The related parameters can include search space ID, monitoring period, symbol position, etc.

[0132] As an example, in the specific search space of the terminal device, the network device or the terminal device can set the symbol position for monitoring the first SIB in each time slot. Illustratively, the symbol position for monitoring can be a plurality of consecutive symbols. Illustratively, the symbol position for monitoring can be set according to odd and even symbols, or in a certain rule.

[0133] As an example, according to the network demand and the capability of the terminal device, the specific search space of the terminal device can be dynamically adjusted. For example, the network device can adjust the specific search space corresponding to the terminal device in real time based on the terminal device capability information and the actual communication demand.

[0134] The terminal device determines the configuration information of the first resource, which can include that the terminal device receives the configuration information of the first resource sent by the network device. That is, the configuration information of the first resource can be detected in the search space, or can be directly received.

[0135] As an example, after the terminal device detects the resource configuration information of the WUS on the first search space, the terminal device can determine the first resource according to the resource configuration information. After determining the first resource, the terminal device can send the first request on the first resource.

[0136] Continuing to refer to FIG. 3, at step S320, the terminal device sends the first request on the first resource. As described above, the first request is used for the terminal device to request the first SIB from the network device.

[0137] In some embodiments, the first SIB is one or more SIBs sent by the network device according to the needs of the terminal device. Therefore, the network device does not need to periodically send the first SIB, but sends the first SIB on demand to achieve energy saving. For example, the network device does not need to send SIB1 according to a period of 160 ms and a transmission repetition period within 160 ms, but sends SIB1 according to the first request.

[0138] In some embodiments, the first SIB includes SIB1. The network device can send SIB1 according to the request of the terminal device, so as to reduce unnecessary SIB1 sending. As an example, the first SIB can include SIB1 and other SIBs in the serving cell, that is, the first SIB can be a part of SIB including SIB1 in the serving cell.

[0139] In some embodiments, the first SIB is the on-demand SIB1 described above. That is, the first SIB can be SIB1.

[0140] In some implementations, when the serving cell is an NES cell, the transmitted SSB can not contain the parameter set of SIB1, so as to reduce transmission overhead. However, part of the configuration of cell random access is provided in SIB1. When the terminal device discovers the serving cell and wants to access the serving cell, since the received SSB does not have SIB1, the terminal device needs to request the first SIB.

[0141] In some embodiments, the first SIB is the SIB required by the terminal device, and the first request can also be called an on-demand SIB request.

[0142] In some embodiments, the network device can send the first SIB at different times on the second search space. When the terminal device detects the first SIB in the second search space, the terminal device needs to perform blind detection on multiple time-frequency resources of the second search space.

[0143] It should be understood that the terminal device detecting the first SIB in the second search space can include detecting the related information of the first SIB. When the time-frequency resources in the second search space are used for directly sending the first SIB, the terminal device can directly listen to the first SIB in the second search space. When the time-frequency resources in the second search space are used for sending the related information of the first SIB, the terminal device receives the first SIB after detecting the related information.

[0144] In some embodiments, the first SIB can be sent through at least one of the plurality of time-frequency resources. In order to facilitate the terminal device to determine the transmission resource of the first SIB, the network device can correspond the time-frequency resource of the first SIB with the index of the synchronization signal block (SSB index). That is, the SSB index received by the terminal device can be associated with the first SIB.

[0145] Exemplarily, in the second search space, the resources of the search space can be respectively identified according to the indexes of different SSBs, so as to distinguish the specific time-frequency resource information corresponding to different SSB indexes. These time-frequency resources can be the plurality of time-frequency resources for sending the first SIB. Therefore, the first SIB sent by the network device at different times can correspond to different SSB indexes, so as to facilitate the terminal device to determine the time-frequency resource of the first SIB according to the received SSB index, thereby receiving the first SIB in time.

[0146] Exemplarily, the terminal device can determine at least one time-frequency resource for sending the first SIB according to the received index of the SSB. Subsequently, the terminal device can receive the first SIB on the at least one time-frequency resource.

[0147] As an example, the plurality of time-frequency resources can be one-to-one corresponding to the plurality of SSBs, so as to more flexibly indicate the time-frequency resource of the first SIB. For example, the indexes of the plurality of time-frequency resources can respectively correspond to the indexes of the plurality of SSBs.

[0148] As an example, any time-frequency resource of the plurality of time-frequency resources can correspond to the plurality of SSBs, so as to apply to some scenes that do not require one-to-one correspondence and reduce signaling overhead. For example, the index of a time-frequency resource can correspond to the indexes of the plurality of SSBs.

[0149] Optionally, the one-to-many relationship between the plurality of time-frequency resources and the plurality of SSBs can be any one of the following: one time-frequency resource corresponds to two SSBs, one time-frequency resource corresponds to four SSBs, one time-frequency resource corresponds to eight SSBs, etc.

[0150] As an embodiment, one time-frequency resource for transmitting the first SIB can be applicable to multiple SSB indexes received by the terminal device. This can be applicable to a scenario where the terminal device has a low moving speed or a surrounding environment changes little. In particular, in the scenario of NTN, the intensity of different SSBs received by the terminal device has little difference, and thus the first SIB transmitted by the time-frequency resource can correspond to all SSBs in one SSB time window.

[0151] As an embodiment, if the terminal device has a high moving speed or is in a complex surrounding environment, one SSB transmission window can also be divided into multiple sub-time windows. Each sub-time window can correspond to multiple SSB indexes, and the first SIB transmitted in one time-frequency resource can correspond to all SSB indexes in the sub-time window.

[0152] As an example, multiple time-frequency resources can correspond to any SSB in multiple SSBs. For example, the indexes of multiple time-frequency resources can correspond to the index of one SSB. Alternatively, the many-to-one relationship between multiple time-frequency resources and multiple SSBs can be any of the following: two time-frequency resources correspond to one SSB, four time-frequency resources correspond to one SSB, eight time-frequency resources correspond to one SSB, and the like.

[0153] As an example, in the case of frequency range 2 (FR2), the network device and the terminal device can know which SSB index on which beam the first SIB corresponds to based on the above correspondence.

[0154] As an example, the SSB indexes in one SSB transmission window can have a correspondence relationship with the on-demand SIB1 and the preamble therein. The on-demand SIB1 can be the time-frequency resource of the on-demand SIB1. The correspondence relationship between the SSB index and the on-demand SIB1 time-frequency resource can be one-to-one or not one-to-one. As described above, one SSB index can correspond to one or more time-frequency resources of the first SIB. Exemplarily, multiple SSB indexes can correspond to one time-frequency resource of the first SIB.

[0155] For ease of understanding, the correspondence relationship between the SSB index and the on-demand SIB1 time-frequency resource is exemplarily described below in combination with FIGS. 4 to 7. In FIGS. 4 to 7, the network device transmits 64 SSBs, which are SSB0 to SSB63 respectively. The multiple time-frequency resources for transmitting the on-demand SIB1 can be represented as S1#0, S1#1, S1#2, and the like respectively.

[0156] In FIG. 4 and FIG. 6, the plurality of SSBs corresponding to the plurality of SSB indexes respectively occupy different time domain resources. In FIG. 5 and FIG. 7, the plurality of SSBs corresponding to the plurality of SSB indexes are time-frequency multiplexed, that is, 2 SSBs in the same time domain resource respectively occupy different frequency domain resources.

[0157] In FIG. 4 and FIG. 5, the plurality of time-frequency resources of the on-demand SIB1 are one-to-one corresponding to the plurality of SSB indexes. As shown in FIG. 4 and FIG. 5, the indexes of the 64 time-frequency resources of the on-demand SIB1 corresponding to the 64 SSB indexes are S1#0 to S1#63 respectively.

[0158] In FIG. 6 and FIG. 7, the SSB indexes are many-to-one corresponding to the time-frequency resources of the on-demand SIB1. As shown in FIG. 6 and FIG. 7, the many-to-one scenario is that 8 SSB indexes correspond to 1 time-frequency resource of the on-demand SIB1, so the indexes of the 64 time-frequency resources of the on-demand SIB1 corresponding to the 64 SSB indexes are S1#0 to S1#7 respectively.

[0159] The above describes, in combination with FIG. 4 to FIG. 7, a plurality of implementation manners of the time-frequency resources of the first SIB corresponding to the SSB. Regardless of which implementation manner is adopted, the time-frequency resources for transmitting the first SIB can belong to the common search space or the specific search space, which is not limited herein.

[0160] The first request can be implemented in a plurality of ways. That is, the first terminal device can transmit information for requesting the first SIB in a plurality of ways. Optionally, the first request can include one or more of the following: WUS, demand information / demand signaling for requesting the first SIB, a first sequence for requesting the first SIB, and a preamble index related to the first SIB.

[0161] As an example, the demand signaling can be control signaling or data signaling, which is not limited herein.

[0162] In some embodiments, after the terminal device transmits the first request, the terminal device can detect the first SIB on the second search space. After the network device receives the first request transmitted by the terminal device, the network device can transmit the first SIB on the second search space so as to be received by the terminal device.

[0163] The above describes, in combination with FIG. 3 to FIG. 7, two embodiments of multiplexing the configuration information of the first resource with the existing search space and configuring a new search space. Regardless of the type of the first search space for the first resource, the time-frequency resources for transmitting the first SIB can have a certain correspondence with the SSB, so as to determine the time domain position of receiving the first SIB according to the received SSB by the terminal device.

[0164] In some embodiments, the terminal device detects a PDCCH on the first search space or the second search space. The PDCCH can indicate the configuration information of the first resource or the first SIB. Exemplarily, the PDCCH can indicate the related information of the first SIB. It should be understood that the PDCCH is only an example, and the PDCCH that can be used to indicate the configuration information of the first resource or the first SIB can be other channels or signals.

[0165] As known from the foregoing, the terminal device does not know which RBs in the CORESET the PDCCH will be transmitted on, and therefore the terminal device needs to perform a blind detection process to locate the PDCCH to be received. In order to minimize or avoid the blind detection process in the search space, the embodiments of the present application further propose a method of directly locating the position of the PDCCH. Through the method, the terminal device can directly locate the PDCCH in the CORESET, so as to more quickly determine the time-frequency resource for sending the first request or determine the first SIB, thereby improving the decoding efficiency.

[0166] In some embodiments, the PDCCH for indicating the configuration information of the first resource or the first SIB corresponds to a control resource set (CORESET), which can be a first control resource set (i.e., a first CORESET). The position of the PDCCH in the first CORESET can be related to one or more of the following information: the starting symbol position of the first CORESET; the number of RBs occupied by each CCE in the first CORESET; the number of symbols or the number of RBs covered by the first CORESET; the number of CCEs included in the PDCCH; and the ID of the terminal device.

[0167] As an example, the starting symbol of the first CORESET is the first symbol of the time domain resource occupied by the first CORESET.

[0168] As an example, the number of RBs occupied by each CCE in the first CORESET can be determined according to a protocol or dynamically indicated.

[0169] As an example, the number of symbols or the number of RBs covered by the first CORESET is determined when the network side is configured.

[0170] As an example, the number of CCEs included in the PDCCH can also be referred to as the number of CCEs corresponding to the CORESET for the terminal device.

[0171] Optionally, the starting position of the PDCCH in the first CORESET can be determined according to the ID of the terminal device and the number of CCEs included in the PDCCH. Assuming that the PDCCH includes N CCE CCEs, N CCE is a positive integer. The starting position of the PDCCH in the first CORESET can be determined by NCCE The index of the starting CCE in the CCEs represents. The index of the starting CCE CCE Index may be:

[0172] CCE Index = UE ID mod N CCE ;

[0173] wherein the UE ID is an ID of the terminal device.

[0174] Optionally, the symbol position of the PDCCH in the first CORESET can be determined according to a starting symbol of the first CORESET, an ID of the terminal device, and a number of symbols covered by the first CORESET. Assuming that the number of symbols covered by the first CORESET is M, M is a positive integer. The symbol position of the PDCCH in the first CORESET PDCCH symbol,position may be:

[0175] PDCCH symbol,position = S0 + (UE ID mod M);

[0176] wherein S0 is the starting symbol position of the first CORESET.

[0177] Optionally, the frequency domain position of the PDCCH in the first CORESET can be determined according to a number of RBs occupied by each CCE, an index of the starting CCE, and a number of RBs covered by the first CORESET. The frequency domain position of the PDCCH in the first CORESET PDCCH frequency,position may be:

[0178] PDCCH frequency,position = (CCE Index x CCE Size ) mod N RB ;

[0179] wherein CCE Size is the number of RBs occupied by each CCE, CCE Size is a positive integer, N RB is the number of RBs covered by the first CORESET, N RB is a positive integer.
