[0035] The network device in this application embodiment can be a device for communicating with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network.

[0040] Signal transmission process in a wireless communication system

[0041] Figure 2 is a flowchart of signal transmission in a wireless communication system applicable to the embodiments of this application. As shown in Figure 2, the signal transmission process in the wireless communication system can be roughly divided into various channel coding processes S211 to S218 as shown in Figure 2.

[0042] In the channel coding process S211, the transmitter performs channel coding on the information to be transmitted (e.g., source bit stream) to obtain the encoded bit stream. The information to be transmitted can be in the form of a bit stream.

[0043] In the modulation process S212, the code stream is modulated into modulation symbols.

[0044] In the pilot insertion process S213, pilot symbols are inserted into the above modulation symbols to form a signal to be transmitted. The pilot symbols can be used by the receiver for channel estimation and symbol detection.

[0045] In transmission signal S214, the aforementioned signal is carried on the channel and transmitted to the receiver. During transmission through the channel, noise is typically added to the signal.

[0046] In the channel estimation process S215, the receiver can perform channel estimation based on the pilot signal to obtain channel state information (CSI), and feed the CSI back to the transmitter through the feedback link so that the transmitter can adjust the channel coding, modulation, precoding and other methods.

[0047] In the symbol detection process S216, symbol detection is performed on the received modulation symbols to obtain the detection results.

[0048] In the demodulation process S217, the received modulation symbols are demodulated based on the detection results to obtain the code stream.

[0049] In the channel decoding process S218, the code stream is decoded to obtain the recovered information (e.g., the recovered bit stream), wherein the recovered information may be in the form of a bit stream.

[0050] It should be understood that the channel coding processes S211 to S218 shown in Figure 2 are merely exemplary examples of common signal processing procedures in wireless communication systems. Wireless communication systems may also include signal processing procedures such as resource mapping, precoding, interference cancellation, and CSI measurement. For the sake of brevity, these will not be elaborated upon further in this application.

[0051] SSB structure

[0052] In some communication systems (e.g., 5G NR), the SSB is designed for enhanced mobile broadband (eMBB) terminal equipment. Referring to Figure 3, the SSB bandwidth is 20 physical resource blocks (PRBs). Taking a subcarrier spacing of 15kHz as an example, the SSB bandwidth is 3.6MHz. The SSB contains four orthogonal frequency division multiplexing (OFDM) symbols in the time domain. The primary synchronization signal (PSS) is located in the first symbol, with a frequency domain width of 12 PRBs. The secondary synchronization signal (SSS) is located in the third symbol, also with a frequency domain width of 12 PRBs. The physical broadcast channel (PBCH) is located in the second to fourth symbols, with a frequency domain width of 20 PRBs in the second and fourth symbols, thus fully utilizing the SSB bandwidth. On the 3rd symbol, it occupies the 4 lowest frequency domain positions and the 4 highest frequency domain positions in the SSB bandwidth, that is, it occupies the other bandwidths besides SSS.

[0053] System Information Receiving Method

[0054] In some communication systems (e.g., 5G NR), system information is carried in the master information block (MIB) and the system information block (SIB). The MIB is carried in the PBCH within the SSB, and the SIB is carried in the PDSCH. Correspondingly, the time-frequency resources of the PDSCH are indicated by the DCI transmitted in CORESET#0. That is, the terminal device can detect the DCI in the Type0 PDCCH common search space of CORESET#0. If the terminal device detects the DCI, it can read the scheduling information from it. This scheduling information indicates the time-frequency resources of the PDSCH transmitting the SIB. Then, the terminal device can receive the SIB on the time-frequency resources of the PDSCH.

[0055] Indication method for CORESET#0

[0056] In some communication systems (e.g., 5G NR), CORESET#0 is the first control resource set to monitor the PDCCH during the initial access process of a terminal device. The location of CORESET#0 is indicated by the MIB carried by the PBCH in the SSB. Since the information that the MIB can carry is very limited, the communication protocol defines several multiplexing modes between CORESET#0 and the SSB. In this way, the MIB can indicate one of the defined multiplexing modes.

[0057] In some implementations, the multiplexing patterns corresponding to the multiplexing modes defined above can be seen in Figures 4A to 4C. The multiplexing pattern shown in Figure 4A adopts time-division multiplexing (TDM). In the time domain, the time-frequency resources of SSB and CORESET#0 do not overlap. In the frequency domain, the bandwidth of CORESET#0 completely or nearly completely covers the bandwidth of SSB.

[0058] The multiplexing pattern shown in Figure 4B employs a combination of TDM and frequency division multiplexing (FDM). In the time domain, the time-frequency resources of SSB and CORESET#0 do not overlap. In the frequency domain, the bandwidth of SSB and CORESET#0 do not overlap and are as close as possible.

[0059] The multiplexing pattern shown in Figure 4C uses FDM. In the time domain, the time-frequency resources of SSB overlap with those of CORESET#0. In the frequency domain, the bandwidth of SSB does not overlap with that of CORESET#0, and they are as close as possible.

[0060] Accordingly, the terminal device can first detect the SSB, determine the multiplexing pattern used by the SSB and CORESET#0 based on the MIB in the PBCH, and then determine the time-frequency resources of CORESET#0 based on the multiplexing pattern. Afterwards, the terminal device can search for the DCI that schedules other system information in CORESET#0, determine the time-frequency resources where the PDSCH carrying system information is located based on the indication of the DCI, and then read the system information from the PDSCH.

[0061] With the development of communication systems, the types of terminal devices introduced are increasing, and different types of terminal devices have different communication needs. If the traditional system information transmission method continues to be used, it may not be able to meet the communication needs of some terminal devices. For example, in a traditional communication system, a terminal device needs to obtain the resource indication information of CORESET#0 from the SSB, detect CORESET#0 to obtain the DCI, and then determine the transmission resources (e.g., time-frequency resources) of the PDSCH carrying system information based on the scheduling information in the DCI, and receive system information on the transmission resources of the PDSCH. In this scheme based on DCI scheduling of system information, on the one hand, the terminal device consumes a lot of energy to detect the DCI. For some terminal devices (e.g., Internet of Things (IoT) devices), it may not be able to provide enough energy to detect the DCI, resulting in the terminal device being unable to obtain system information. On the other hand, the terminal device consumes a lot of time to detect the DCI. For some terminal devices that require low-latency communication, it may not be able to meet the requirements of low-latency communication.

[0062] Therefore, to address the aforementioned problems, this application provides a method for transmitting system information. In this method, the system information may include a first part of system information and a second part of system information. The transmission resources for the first part of the system information can be determined based on the transmission resources of the SSB, while the transmission resources for the second part of the system information are scheduled by the DCI associated with the SSB. Compared to the traditional method of transmitting system information based on DCI scheduling, this method helps to improve the flexibility of transmitting system information and meet the communication needs of different types of terminal devices.

[0063] For ease of understanding, the wireless communication method of this application embodiment is described below with reference to FIG5. The method described in FIG5 includes step S510.

[0064] In step S510, the network device sends system information, and correspondingly, the terminal device receives the first part of the system information and / or the second part of the system information.

[0065] In some implementations, the first part of the system information may correspond to a first type of terminal device, and the first part of the system information and / or the second part of the system information may correspond to a second type of terminal device, wherein the frequency domain range (or bandwidth processing capability) supported by the second type of terminal device is greater than the frequency domain range (or bandwidth processing capability) supported by the first type of terminal device. The first part of the system information corresponding to a first type of terminal device can be understood as the first type of terminal device being able to communicate with the network device solely based on the first part of the system information. The first part of the system information and / or the second part of the system information corresponding to a second type of terminal device can be understood as the second type of terminal device being able to communicate with the network device based on the first part of the system information and / or the second part of the system information.

[0066] In some implementations, the terminal device may receive only the first part of the system information and communicate with the network device based on the first part of the system information. In other implementations, the terminal device may receive both the first part of the system information and the second part of the system information and communicate with the network device based on both. Of course, in the embodiments of this application, the terminal device may receive only the second part of the system information and communicate with the network device based on the second part of the system information.

[0067] In some implementations, the first part of the system information and / or the second part of the system information may be system information not carried in the SSB. For example, the first part of the system information and / or the second part of the system information may be system information carried in the SIB in conventional schemes; therefore, the first part of the system information is also called the first part of the SIB, and the second part of the system information is also called the second part of the SIB. As another example, the first part of the system information and / or the second part of the system information may be system information carried in the PDSCH. Yet another example is that the first part of the system information and / or the second part of the system information may be other system information in a known communication system besides the system information carried in the MIB.

[0068] It should be noted that the system information carried in the SIB is not limited in the embodiments of this application. For example, the system information carried by the SIB may be the system information carried by one or more SIBs from SIB1 to SIB5. For another example, the system information carried by the SIB may be the system information carried in SIB1. For another example, the system information carried by the SIB may be the system information carried in SIB2. For another example, the system information carried by the SIB may be the system information carried in SIB3. For another example, the system information carried by the SIB may be the system information carried in SIB4. For another example, the system information carried by the SIB may be the system information carried in SIB5.

[0069] In some implementations, the transmission resources for the first part of the system information can be determined based on the transmission resources of the SSB (e.g., time-frequency resources). Compared with the traditional scheme of detecting the DCI to determine the transmission resources of the system information, this helps to reduce the latency of the terminal device in obtaining the system information.

[0070] Taking transmission resources including frequency domain resources as an example, in some implementations, the frequency domain resources of the first part of the system information are the same as the frequency domain resources of the SSB, for example, see Figure 6. Of course, in the embodiments of this application, the frequency domain range corresponding to the first part of the system information is located within the frequency domain range corresponding to the SSB, for example, see Figure 9A.

[0071] Taking transmission resources, including time-domain resources, as an example, in some implementations, the time-domain resources of the first part of the system information are adjacent to the time-domain resources of the SSB; in other words, the transmission resources of the first part of the system information and the transmission resources of the SSB are adjacent in the time domain. In other implementations, the time-domain resources of the first part of the system information and the time-domain resources of the SSB are separated by a first time-domain offset, wherein the first time-domain offset can be predefined, pre-configured, or configured by the network device.

[0072] In other implementations, the transmission resources of the second part of the system information are scheduled by the DCI associated with the SSB. The DCI associated with the SSB can be understood as a DCI searched in the control resource set (e.g., CORESET#0) indicated by the SSB, or a DCI detected on the control resource set (e.g., CORESET#0) indicated by the MIB in the SSB. In the embodiments of this application, scheduling the transmission resources of the second part of the system information via DCI helps to improve the flexibility of the transmission resources of the second part of the system information.

[0073] In some implementations, the transmission resources of the first part of the system information and the transmission resources of the SSB are time-division multiplexed, for example, as shown in Figure 6. In other implementations, the transmission resources of the first part of the system information and the transmission resources of the SSB can be combined using a combination of time-division multiplexing and frequency-division multiplexing. This application does not limit this approach.

[0074] With the development of communication systems, the types of terminal devices introduced are increasing, and different types of terminal devices have different capabilities. If traditional system information transmission methods are continued, some terminal devices may be unable to obtain system information. For example, in traditional communication systems, system information occupies a fixed frequency domain range (also known as bandwidth) for transmission. However, different types of terminal devices support different sizes of frequency domain ranges. For terminal devices that support a frequency domain range smaller than the aforementioned fixed frequency domain range, they may not be able to receive system information within the fixed frequency domain range.

[0075] Therefore, in view of the above problems, another embodiment of this application provides a method for transmitting system information. In this scheme, the system information may include a first part of system information and a second part of system information. The frequency domain range occupied by the first part of system information is different from that occupied by the second part of system information. Accordingly, the terminal device can select to obtain the first part of system information and / or the second part of system information based on the different frequency domain ranges supported, which helps to improve the success rate of obtaining system information.

[0076] In some implementations, the frequency domain range occupied by the first part of the system information is smaller than that occupied by the second part of the system information; in other words, the bandwidth occupied by the first part of the system information is smaller than that occupied by the second part of the system information. Of course, in the embodiments of this application, the frequency domain range occupied by the first part of the system information can be larger than that occupied by the second part of the system information; in other words, the bandwidth occupied by the first part of the system information is larger than that occupied by the second part of the system information. For ease of description, the following description will use the example of the first part of the system information occupying a smaller bandwidth than the second part of the system information.

[0077] In some scenarios, as described above, system information can be divided into multiple parts to occupy different frequency ranges (or bandwidths) in order to support terminal devices with different frequency ranges to obtain it. Therefore, the above system information can also be called "multi-bandwidth system information".

[0078] In some implementations, the amount of time-domain resources occupied by the first part of the system information can be greater than the amount of time-domain resources occupied by the second part of the system information, so as to reduce the time for the terminal device to obtain the second part of the system information.

[0079] The following section, in conjunction with Relationships 1 to 3, describes the relationship between the first part of the system information and the second part of the system information in the embodiments of this application.

[0080] In relation 1, the first part of the system information is the same as the second part of the system information, or in other words, the first part of the system information and the second part of the system information contain the same content.

[0081] In some implementations, the first part of the system information and / or the second part of the system information can be all the system information sent by the network device. Of course, in the embodiments of this application, the first part of the system information and / or the second part of the system information can be a portion of the system information sent by the network device.

[0082] In this embodiment, the system information sent by the network device is not limited. For example, the system information sent by the network device may be all system information carried by the SIB. As another example, the system information sent by the network device may include all system information not carried by the SSB. Yet another example, the system information sent by the network device may include all system information carried by the PDSCH.

[0083] In some implementations, the first part of the system information and / or the second part of the system information may include all system information sent by the network device, which can be understood as the first part of the system information and / or the second part of the system information may include all SIBs (full SIBs).

[0084] In some implementations, the first part of the system information and / or the second part of the system information may include some information from the system information sent by the network device, which can be understood as the first part of the system information and / or the second part of the system information may include some SIBs.

[0085] In some implementations, the aforementioned system information may be basic system information used for communication between terminal devices and network devices. Therefore, this system information may also be referred to as basic system information or foundational system information. Taking SIB as an example, basic system information is also called basic SIB, and foundational system information is also called foundational SIB.

[0086] In this application embodiment, the content carried by the basic system information is not limited. For example, the basic system information may include one or more of the following: downlink common configuration (represented as downlinkConfigCommon); n-TA offset (represented as n-TimingAdvanceOffset); SSB transmit power (represented as ss-PBCH-BlockPower); SSB period of the serving cell (represented as ssb-periodicityServingCell); and time division duplexing (TDD) uplink and downlink common configuration (represented as tdd-UL-DL-ConfigurationCommon).

[0087] In some implementations, downlink common configuration is used to indicate the downlink common configuration of the serving cell. For example, downlink common configuration may include frequency domain information configuration and initial downlink bandwidth part (BWP) common configuration.

[0088] In some implementations, the n-TA offset is used to indicate the TA offset used for random access in the serving cell.

[0089] In some implementations, the SSB transmit power is used to indicate the transmit power of the network device sending the SSB. Typically, the terminal device can estimate the transmit power of the RA preamble based on this information.

[0090] In some implementations, the SSB period indicated by the serving cell's SSB period is used for rate matching.

[0091] In some implementations, the TDD uplink / downlink common configuration is used to indicate the cell-specific TDD uplink / downlink common configuration.

[0092] In some implementations, for terminal devices that support a narrow frequency range, the terminal device can obtain a first part of the system information so that it can communicate with network devices based on the first part of the system information, which helps to increase the likelihood of this type of terminal device obtaining system information.

[0093] In some implementations, for terminal devices supporting a wide frequency range, the terminal device can obtain both the first part of the system information and the second part of the system information to facilitate subsequent communication with network devices based on the first and second parts of the system information, thus improving the reliability of the system information acquisition by this type of terminal device. Of course, in the embodiments of this application, for terminal devices supporting a wide frequency range, this type of terminal device may only receive the second part of the system information, or it may only receive the first part of the system information.

[0094] As mentioned above, the first part of the system information is the same as the second part of the system information, and the frequency domain range occupied by the first part of the system information is smaller than that occupied by the second part of the system information. In this case, the amount of time domain resources occupied by the second part of the system information can be less than the amount of time domain resources occupied by the first part of the system information, which helps to reduce the time for the terminal device to obtain the second part of the system information, as shown in Figure 6.

[0095] In relation 2, the information carried by the first part of the system information is part of the information carried by the second part of the system information. In other words, the second part of the system information may include the first part of the system information, as well as other system information besides the first part of the system information.

[0096] In some implementations, the second part of the system information can be system information sent by the network device. In this case, the information carried by the first part of the system information is a portion of the information carried by the second part of the system information. This can be understood as the first part of the system information carrying a portion of the system information sent by the network device. Of course, in this embodiment, the second part of the system information can be a portion of the system information sent by the network device.

[0097] In some implementations, the second part of the system information can be all the system information sent by the network device, while the first part of the system information can include basic system information (also known as fundamental system information). For an introduction to basic system information, please refer to the above text.

[0098] In this embodiment, the system information sent by the network device is not limited. For example, the system information sent by the network device may be all system information carried by the SIB. As another example, the system information sent by the network device may include all system information not carried by the SSB. Yet another example, the system information sent by the network device may include all system information carried by the PDSCH.

[0099] For example, the system information sent by the network device can be all the system information carried by the SIB. Then the second part of the system information can be the complete SIB (i.e., all the SIBs introduced above). Correspondingly, the first part of the system information can be a partial SIB (e.g., the basic SIB introduced above). For an introduction to the basic SIB, please refer to the above.

[0100] In some implementations, for terminal devices that support a narrow frequency range, the terminal device can obtain a first part of the system information so that it can communicate with network devices based on the first part of the system information, which helps to increase the likelihood of this type of terminal device obtaining system information.

[0101] In some implementations, for terminal devices supporting a wide frequency range, the terminal device can acquire a second part of the system information to facilitate subsequent communication with network devices based on this second part of the system information. Since the second part of the system information carries more complete content than the first part, the terminal device acquiring the second part of the system information can implement richer system functions with the network device, which helps improve the transmission capacity and spectral efficiency of this type of terminal device. Of course, in this embodiment, for terminal devices supporting a wide frequency range, this type of terminal device can receive both the first part of the system information and the second part of the system information to improve the reliability of acquiring the first part of the system information.

[0102] In relation 3, the information carried by the first part of the system information is different from the information carried by the second part of the system information. In other words, the second part of the system information does not contain the first part of the system information, and the second part of the system information only contains other system information besides the first part of the system information.

[0103] In some implementations, the first part of the system information and the second part of the system information can constitute all the system information sent by the network device. Of course, in the embodiments of this application, the first part of the system information and the second part of the system information can be only a portion of the system information sent by the network device.

[0104] In some implementations, the first part of the system information may include basic system information (also known as fundamental system information). Correspondingly, the second part of the system information may include other system information besides the basic system information. Therefore, the second part of the system information is also called supplementary system information or additional system information. For an introduction to basic system information, please refer to the above text.

[0105] In this embodiment, the system information sent by the network device is not limited. For example, the system information sent by the network device may be all system information carried by the SIB. As another example, the system information sent by the network device may include all system information not carried by the SSB. Yet another example, the system information sent by the network device may include all system information carried by the PDSCH.

[0106] For example, the system information sent by a network device can be all the system information carried by an SIB. The first part of the system information can include the basic SIB, and the second part of the system information can include the additional SIB. For an introduction to the basic SIB, please refer to the above. Correspondingly, the additional SIB can carry other system information carried in the SIB other than the basic SIB.

[0107] In some implementations, the first part of the system information can be jointly encoded with the second part of the system information, which helps to improve the encoding performance of both parts of the system information.

[0108] In some implementations, for terminal devices that support a narrow frequency range, the terminal device can obtain a first part of the system information so that it can communicate with network devices based on the first part of the system information, which helps to increase the likelihood of this type of terminal device obtaining system information.

[0109] In some implementations, for terminal devices supporting a wide frequency range, the terminal device can acquire both the first part of the information and the second part of the system information to facilitate subsequent communication with network devices based on these two parts of information. Since this type of terminal device can acquire both the first part of the information and the second part of the system information, richer system functions can be implemented between the terminal device and the network device, which helps improve the transmission capacity and spectral efficiency of this type of terminal device. Of course, in this embodiment, for terminal devices supporting a wide frequency range, this type of terminal device may only receive the first part of the system information.

[0110] The foregoing described the indication method of system information transmission resources in the embodiments of this application, as well as the relationship between the first part of system information and the second part of system information. In the embodiments of this application, the system information transmission method and the above-mentioned association relationship can be used alone or in combination. Taking the combination as an example, the transmission resources of the first part of system information can be determined based on the transmission resources of SSB, and the transmission resources of the second part of system information can be based on the DCI scheduling associated with SSB. Of course, in the embodiments of this application, the transmission resources of the second part of system information can be determined based on the transmission resources of SSB, and the transmission resources of the first part of system information can be based on the DCI scheduling associated with SSB.

[0111] As mentioned above, different types of terminal devices have different capabilities. Continuing to use the traditional SSB transmission method may result in some terminal devices being unable to receive SSBs. For example, in traditional communication systems, SSBs occupy a fixed frequency range (also known as bandwidth) for transmission. However, different types of terminal devices support different frequency ranges. For terminal devices that support a frequency range smaller than the aforementioned fixed range, they may not be able to receive SSBs within that fixed frequency range. In this case, designing a separate initial access signal and access method for this type of terminal device could drastically increase system complexity and signaling overhead.

[0112] Therefore, in view of the above problems, this application also provides a transmission method for SSB. In this scheme, SSB may include a first part of information and a second part of information. The size of the frequency domain range corresponding to the first part of information is different from the size of the frequency domain range corresponding to the second part of information. Accordingly, the terminal device can select to obtain the first part of information and / or the second part of information based on the supported frequency domain range, which helps to improve the success rate of obtaining SSB.

[0113] In some implementations, the frequency domain range corresponding to the first part of the information is smaller than the frequency domain range corresponding to the second part of the information, or in other words, the bandwidth corresponding to the first part of the information is smaller than the bandwidth corresponding to the second part of the information.

[0114] It should be noted that the frequency domain range corresponding to the first part of the information can refer to the frequency domain range between the lowest and highest frequency domain positions in the frequency domain resources used to transmit the first part of the information. The first part of the information may not necessarily occupy all the frequency domain resources within this range. Similarly, the frequency domain range corresponding to the second part of the information can refer to the frequency domain range between the lowest and highest frequency domain positions in the frequency domain resources used to transmit the second part of the information. The second part of the information may not necessarily occupy all the frequency domain resources within this range.

[0115] In some implementations, the first and second parts of the information are information transmitted via the PBCH in the SSB. That is to say, in the embodiments of this application, the information transmitted via the PBCH in the SSB can correspond to multiple frequency domain ranges (or multiple bandwidths). Therefore, this SSB is also called a multi-bandwidth SSB.

[0116] In this application embodiment, the relationship between the first part of the information and the second part of the information is not limited. In some implementations, the first part of the information may be a portion of the information transmitted in the SSB via the PBCH, and correspondingly, the second part of the information may be other information besides the first part of the information. In other implementations, the first part of the information may be a portion of the information transmitted in the SSB via the PBCH, and the second part of the information may include the first part of the information, as well as other information transmitted in the SSB via the PBCH besides the first part of the information. Of course, in this application embodiment, the first part of the information and the second part of the information may be the same information.

[0117] As mentioned above, the first part of the information can be the basic information transmitted via the PBCH used for communication between the terminal device and the network device; therefore, this information is also called the "basic PBCH". Correspondingly, the second part of the information can be other information transmitted via the PBCH besides the first part of the information; therefore, the second part of the information can also be called the "additional PBCH".

[0118] In some implementations, the frequency domain range corresponding to the SSS and / or PSS in the SSB can be the same as the frequency domain range corresponding to the first part of the information, in order to improve the success rate of the terminal device in obtaining the SSS and / or PSS. For related information, please refer to the SSB shown in Figure 9A.

[0119] In some implementations, the frequency domain range corresponding to the first part of the information is the same as the frequency domain range occupied by the first part of the system information, which helps to simplify the complexity of the terminal device receiving the first part of the information and the first part of the system information. Of course, in the embodiments of this application, the frequency domain range corresponding to the first part of the information can be smaller than the frequency domain range occupied by the first part of the system information, or the frequency domain range corresponding to the first part of the information can be larger than the frequency domain range occupied by the first part of the system information, which helps to improve the flexibility of transmitting the first part of the information and the first part of the system information.

[0120] In some implementations, the frequency domain range corresponding to the second part of the information is the same as the frequency domain range corresponding to the SSB, which helps simplify the complexity of the terminal device receiving the second part of the information and the SSB. Of course, in the embodiments of this application, the frequency domain range corresponding to the second part of the information can be smaller than the frequency domain range corresponding to the SSB, or the frequency domain range corresponding to the second part of the information can be larger than the frequency domain range corresponding to the SSB, which helps improve the flexibility of transmitting the second part of the information and the SSB.

[0121] In some implementations, the frequency domain range corresponding to the second part of the information includes the frequency domain range corresponding to the first part of the information, which helps to simplify the complexity of the terminal device receiving the first part of the information and the second part of the information.

[0122] In some implementations, the system information carried in the second part of the information is different from the system information carried in the first part of the information. For example, the system information carried in the second part of the information and the first part of the information may include information carried in the MIB in a known communication system.

[0123] In some implementations, the system information carried in the second part of the information is used to indicate the transmission resources of the DCI (for example, see the introduction to the common subcarrier spacing below), while the system information carried in the first part of the information is not used to indicate the transmission resources of the DCI. The information used to indicate the transmission resources of the DCI may be, for example, information indicating the transmission resources of CORESET#0 (also known as the resource indication information of CORESET#0).

[0124] In the embodiments of this application, the content carried by the first part of the information is not limited. In some implementations, the first part of the information is used to indicate the transmission resources of the system frame number and / or demodulation reference signal (DMRS), wherein the DMRS may be carried, for example, on a PDSCH, which is used to carry the aforementioned system information (e.g., the first part of the system information and / or the second part of the system information).

[0125] In the embodiments of this application, the content carried by the second part of the information is not limited. In some implementations, the second part of the information is used to indicate one or more of the following: transmission resource information of PDCCH, information of the initial bandwidth portion (initial BWP), and information of the common subcarrier spacing.

[0126] In some implementations, the PDCCH transmission resource information mentioned above includes the size of the PDCCH transmission resources and / or the transmission resources of the first CORESET (e.g., CORESET#0). The first CORESET includes the search space for PDCCHs with scheduling system information, which may be, for example, the Type0 PDCCH common search space.

[0127] In some implementations, the information of the initial bandwidth portion includes the size and / or location of the initial bandwidth portion. In the embodiments of this application, the initial bandwidth portion is not limited. In some implementations, the initial bandwidth portion may include the first downlink BWP activated after cell search, and / or the first uplink BWP activated after cell search.

[0128] In some implementations, the aforementioned common subcarrier spacing may include one or more of the following: the subcarrier spacing used for system information transmission; the subcarrier spacing used for initial access; and the subcarrier spacing used for random access procedures.

[0129] In some implementations, the common subcarrier spacing can be used to determine the location of the transmission resources and / or initial bandwidth portion of the system information. This can be understood as the common subcarrier spacing being used to determine the transmission resources of CORESET#0 corresponding to the PDCCH of the scheduling system information. Accordingly, the DCI monitored in CORESET#0 is used to indicate the transmission resources of the system information (e.g., the second system information).

[0130] For example, the first part of the information is used to indicate the system frame number and / or the transmission resources of the DMRS, and the second part of the information is used to indicate one or more of the following: transmission resource information of the PDCCH, information of the initial bandwidth portion, and information of the common subcarrier spacing.

[0131] In some implementations, the system information carried in the second part of the information is contained within the first part of the system information. In this way, the terminal device can obtain the second part of the information by receiving the first part of the system information, which helps the terminal device obtain the complete first part of the information and the second part of the information. For a related description, please refer to Figure 9B.

[0132] For ease of understanding, the system information transmission scheme in the embodiments of this application is described below with reference to Figures 6 to 11. Figure 6 is a schematic diagram of transmitting multi-bandwidth system information in an embodiment of this application.

[0133] Referring to Figure 6, assuming the frequency domain range corresponding to SSB is W1, the first part of the system information occupies the frequency domain range W1, and the time domain resources occupied by the first part of the system information are adjacent to the time domain resources corresponding to SSB. Furthermore, CORESET#0 and SSB are FDM multiplexed, where the DCI in CORESET#0 is used to indicate the time-frequency resources occupied by the second part of the system information. The frequency domain range W2 occupied by the second part of the system information is greater than the frequency domain range W1 occupied by the first part of the system information.

[0134] Accordingly, the terminal device can receive the PBCH from the SSB to obtain the MIB information. Then, the method of receiving the SIB can be divided into two types based on the frequency range supported by the terminal device: For terminal devices with a smaller supported frequency range, the terminal device can determine the time-frequency resources of the PDSCH carrying the first part of the system information based on the time-frequency position of the SSB. In this case, the time-frequency resources of the PDSCH carrying the first part of the system information do not require MIB indication.

[0135] For terminal devices that support a wide frequency range, the terminal device can determine the time-frequency position of CORESET#0 based on the MIB, and then determine the time-frequency resources of the PDSCH carrying the second part of the system information based on the scheduling information in the DCI detected in CORESET#0, and receive the second part of the system information in the PDSCH on the time-frequency resources.

[0136] In this embodiment, for terminal devices supporting a smaller frequency range, initial access and reception of MIBs and SIBs can be completed within that smaller frequency range (e.g., W1). For terminal devices supporting a larger frequency range, MIBs and SIBs can be received within that larger frequency range (e.g., W2). Thus, the solution in this embodiment can be applied to terminal devices supporting multiple frequency ranges to receive SIBs and MIBs. Compared to designing a separate system information reception process for terminal devices supporting a smaller frequency range, this helps reduce the complexity of transmitting system information, reduces the additional signaling overhead caused by system information scheduling, and thereby improves the system's spectral efficiency.

[0137] As mentioned above, the relationship between the first part of the system information and the second part of the system information can be divided into three types. The following section, in conjunction with Figures 6 to 8, describes the transmission schemes of the first part of the system information and the second part of the system information in different relationships in the embodiments of this application.

[0138] Referring again to Figure 6, assume that the first and second parts of the system information contain the same content, i.e., both the first part of the system information within frequency range W1 and the second part of the system information within frequency range W2 are complete system information. In this case, terminal devices supporting a smaller frequency range can receive the first part of the system information. Terminal devices supporting a larger frequency range can receive either the first part of the system information or the second part of the system information. Since the frequency range corresponding to the second part of the system information is wider than that corresponding to the first part, the second part of the system information can correspond to fewer time-domain resources. That is, the terminal device can complete the reception of the second part of the system information in a shorter time, which helps to speed up the initial access process.

[0139] Referring to Figure 7, assuming the second part of the system information includes the first part of the system information, and also includes other system information besides the first part, the first part of the system information within the frequency domain range W1 is the basic system information, and the second part of the system information within the frequency domain range W2 is the complete system information. In this case, for terminal devices supporting a smaller frequency domain range, the first part of the system information (i.e., the basic system information) can be received. For terminal devices supporting a larger frequency domain range, either the first part of the system information (i.e., the basic system information) or the second part of the system information (i.e., the complete system information) can be received.

[0140] In this embodiment, if a terminal device supporting a larger frequency range receives the second part of the system information (i.e., complete system information), then this type of terminal device can receive more complete system information, realize richer system functions, and help improve the transmission capacity and spectral efficiency of this type of terminal device. Conversely, for terminal devices supporting a smaller frequency range, only basic system information can be received, which helps avoid receiving unnecessary complex system information and reduces the overhead of the received system information.

[0141] Referring to Figure 8, the second part of the system information includes system information other than the first part. In this case, the first part of the system information can be basic system information, and the second part can be supplementary system information. The basic system information and the supplementary system information can constitute complete system information. Accordingly, the first part of the system information is transmitted within the frequency domain range W1, and the second part of the system information is transmitted within the frequency domain range W2. For terminal devices supporting a smaller frequency domain range, the first part of the system information (basic system information) can be received. For terminal devices supporting a larger frequency domain range, both the first part of the system information (basic system information) and the second part of the system information (supplementary system information) can be received.

[0142] In some implementations, basic system information and additional system information can be jointly encoded, which helps improve the encoding performance of system information.

[0143] In this embodiment, terminal devices supporting a wider frequency range can receive more complete system information (basic system information and additional system information), enabling richer system functions and helping to improve the transmission capacity and spectral efficiency of this type of terminal device. Conversely, for terminal devices supporting a narrower frequency range, only basic system information can be received, helping to avoid receiving unnecessary complex system information and reducing the overhead of the received system information.

[0144] It should be noted that the time-frequency resource locations of the PDSCH carrying the second part of system information in Figures 6 to 8 are for illustrative purposes only, and these time-frequency resources can be flexibly scheduled by the DCI. For example, the time-frequency resources of the PDSCH carrying the first part of system information may not be adjacent to the PDSCH carrying the second part of system information in the frequency domain. Similarly, the time-frequency resources of CORESET#0 corresponding to the DCI may not be adjacent to the PDSCH carrying the second part of system information in the time domain.

[0145] Furthermore, this application embodiment does not limit the relationship between the time-frequency resources corresponding to the SSB and the time-frequency resources of the PDSCH carrying the first part of system information. For example, the time-frequency resources corresponding to the SSB and the time-frequency resources of the PDSCH carrying the first part of system information may be separated by a first time-domain offset, wherein the first time-domain offset is predefined.

[0146] The transmission method of multi-bandwidth system information in the embodiments of this application has been described above with reference to Figures 6 to 8. The following section describes the scheme of combining multi-bandwidth SSB and multi-bandwidth system information in the embodiments of this application with reference to Figures 9A to 11. Assume that the SSB corresponds to frequency domain range W1 and frequency domain range W3, and frequency domain range W3 is a part of frequency domain range W1. Accordingly, PBCH can be divided into two parts: a first part of information (also known as "basic PBCH") and a second part of information (also known as "additional PBCH"). That is to say, the additional PBCH contains other information besides the basic PBCH, wherein the first part of information occupies frequency domain range W3, and the second part of information occupies other frequency domain ranges in frequency domain range W1 besides frequency domain range W3. In addition, multi-bandwidth system information includes a first part SIB and a second part SIB, wherein the first part SIB occupies frequency domain range W3.

[0147] Figure 9A illustrates a scheme in which multi-bandwidth SSBs are combined with multi-bandwidth system information satisfying Relationship 1 in an embodiment of this application. Referring to Figure 9A, in Relationship 1, both the first part SIB and the second part SIB are complete SIBs. The PSS, SSS, basic PBCH, and PDSCH carrying the first part SIB are transmitted within the frequency domain range W3. Additionally, the supplementary PBCH may carry a MIB to indicate the time-frequency position of CORESET#0, and the basic PBCH does not contain this MIB.

[0148] For terminal devices supporting a smaller frequency range, the PSS, SSS, basic PBCH, and PDSCH carrying the first part of the SIB can be received within frequency range W3. For terminal devices supporting a larger frequency range, the complete SSB, including PSS, SSS, basic PBCH, and supplementary PBCH, can be received within frequency range W1. Then, the terminal device can read the resource indication information of CORESET#0 from the MIB of the supplementary PBCH, and search for the DCI that schedules the PDSCH carrying the second part of the SIB within CORESET#0 based on this information. Afterwards, the terminal device can determine the PDSCH resource carrying the second part of the SIB based on the scheduling information in the DCI, and receive the second part of the SIB on the PDSCH resource.

[0149] In some implementations, since both the first and second SIBs are complete SIBs, terminal devices supporting a larger frequency range can also receive the first SIB within the frequency range W3. Of course, in the embodiments of this application, the terminal device can choose to receive either the first or second SIB, or it can receive both, to further improve the SIB reception performance.

[0150] In the embodiments of this application, for terminal devices supporting a smaller frequency domain range, the entire cell search can be completed within the frequency domain range W3, and the basic PBCH and SIB can be received. For terminal devices supporting a larger frequency domain range, cell search and reception of the complete PBCH (including the basic PBCH and the supplementary PBCH) and SIB can be completed within a larger frequency domain range, enabling richer system functions and improving the transmission capacity and spectral efficiency of this type of terminal device.

[0151] In some implementations, to support terminal devices with smaller frequency ranges in obtaining the complete PBCH, the additional PBCH that cannot be transmitted within the basic PBCH can be combined with the first part of the SIB and transmitted within the frequency range W3. This enables richer system functions and improves the transmission capacity and spectral efficiency of the terminal devices. For example, as shown in Figure 9B, based on the scheme shown in Figure 9A, the additional PBCH and the first part of the SIB are combined and transmitted within the frequency range W3.

[0152] Figure 10 illustrates the scheme of combining multi-bandwidth SSBs with multi-bandwidth system information satisfying Relationship 2 in an embodiment of this application. Referring to Figure 10, in Relationship 2, the first part of the SSB is the basic SSB, and the second part of the SSB is the complete SSB. The PSS, SSS, basic PBCH, and PDSCH carrying the first part of the SSB are transmitted within the frequency domain range W3. Additionally, the supplementary PBCH may carry a MIB to indicate the time-frequency position of CORESET#0, and the basic PBCH does not contain this MIB.

[0153] For terminal devices supporting a smaller frequency range, the PSS, SSS, basic PBCH, and PDSCH carrying the basic SIB can be received within frequency range W3. For terminal devices supporting a larger frequency range, the PSS, SSS, basic PBCH, and supplementary PBCH can be received within frequency range W1, and more MIB information can be read from the supplementary PBCH. Then, the terminal device can read the resource indication information of CORESET#0 from the MIB of the supplementary PBCH, and search for the DCI that schedules the PDSCH carrying the complete SIB within CORESET#0 based on this information. Next, the terminal device can determine the resource of the PDSCH carrying the complete SIB based on the scheduling information in the DCI, and receive the complete SIB on that PDSCH resource.

[0154] In this embodiment, terminal devices supporting a smaller frequency range can complete all cell searches and receive basic PBCH and basic SIB within the frequency range W3, simplifying the initial access process for the terminal device. Terminal devices supporting a larger frequency range can complete cell searches and receive complete PBCH and complete SIB within a larger frequency range, enabling richer system functions and improving the transmission capacity and spectral efficiency of terminals with stronger frequency range capabilities.

[0155] Figure 11 illustrates the scheme of combining multi-bandwidth SSBs with multi-bandwidth system information satisfying Relationship 3 in an embodiment of this application. Referring to Figure 11, in Relationship 3, the first part of the SSB is the basic SSB, and the second part of the SSB is the supplementary SSB. The PSS, SSS, basic PBCH, and PDSCH carrying the first part of the SSB are transmitted within the frequency domain range W3. Additionally, the supplementary PBCH may carry a MIB to indicate the time-frequency position of CORESET#0, and the basic PBCH does not contain this MIB.

[0156] For terminal devices supporting a smaller frequency range, the PSS, SSS, basic PBCH, and PDSCH carrying the basic SIB can be received within frequency range W3. For terminal devices supporting a larger frequency range, the PSS, SSS, basic PBCH, and supplementary PBCH can be received within frequency range W1, and more MIB information can be read from the supplementary PBCH. Then, the terminal device can read the resource indication information of CORESET#0 from the MIB of the supplementary PBCH, and search for the DCI that schedules the PDSCH carrying the supplementary SIB within CORESET#0 based on this information. Then, the terminal device can determine the resources of the PDSCH carrying the supplementary SIB based on the scheduling information in the DCI, and receive the supplementary SIB on the resources of that PDSCH. Simultaneously, terminal devices supporting a larger frequency range can also receive the PDSCH carrying the supplementary SIB within frequency range W3, and obtain complete SIB information based on the basic SIB and supplementary SIB.

[0157] In some implementations, the basic SIB and the supplementary SIB can be jointly encoded, which helps improve the receiving performance of the SIB. Of course, in the embodiments of this application, the basic SIB and the supplementary SIB can be encoded independently of each other.

[0158] In this embodiment, terminal devices supporting a smaller frequency range can complete all cell searches and receive basic PBCH and basic SIB within frequency range W3, simplifying the initial access process for the terminal device. Terminal devices supporting a larger frequency range can complete cell searches and receive complete PBCH and complete SIB within a larger frequency range (i.e., frequency range W1), enabling richer system functions and improving the transmission capacity and spectral efficiency of this type of terminal device.

[0159] It should be noted that the positional relationship between the time-frequency resources of CORESET#0 and the time-frequency resources of SSB shown in Figures 9A to 11 is only an example. In this embodiment, the positional relationship between the time-frequency resources of CORESET#0 and the time-frequency resources of SSB can be applied to any of the relationships shown in Figures 4A, 4B, or 4C. Of course, in this embodiment, the positional relationship between the time-frequency resources of CORESET#0 and the time-frequency resources of SSB can also be other schemes introduced in future communication systems.

[0160] The method embodiments of this application have been described in detail above with reference to Figures 1 to 11. The apparatus embodiments of this application will be described in detail below with reference to Figures 12 to 14. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments; therefore, any parts not described in detail can be referred to the preceding method embodiments.

[0161] Figure 12 is a schematic diagram of a terminal device according to an embodiment of this application. The terminal device 1200 shown in Figure 12 includes a receiving unit 1210.

[0162] The receiving unit 1210 is configured to receive a first part of system information and / or a second part of system information from system information sent by a network device. The first part of system information is not carried in a Synchronization Signal / Physical Broadcast Channel Block (SSB). The transmission resources of the first part of system information are determined based on the transmission resources of the SSB. The transmission resources of the second part of system information are scheduled by downlink control information (DCI) searched in the control resource set indicated by the SSB.

[0163] In some implementations, the frequency domain range occupied by the first part of the system information is smaller than the frequency domain range occupied by the second part of the system information.
