AI Technical Summary
In new radio (NR) networks, the transmission of system information blocks (SIBs) is challenging due to the large amount of data required for TRS/CSI-RS configuration information, which exceeds the capacity of a single SIB.
The method involves segmenting the target system information into multiple segments and transmitting these segments to the terminal device, where they can be combined to form the complete system information. This includes transmitting segment indication information and scheduling information to ensure proper combination and timing of the segments.
This approach prevents the need for transmitting large amounts of data in a single SIB, improving the reliability and efficiency of system information transmission by allowing segments to be carried across multiple SIBs or SIB-segments.

[0055] Exemplary embodiments will now be described in detail, examples of which are illustrated in the drawings. Where the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise stated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.
[0056] The terms used in the embodiments of the present disclosure are merely for the purpose of describing particular embodiments and are not intended to limit the embodiments of the present disclosure.

In addition, the term "and / or" as used herein refers to any or all possible combinations of one or more of the associated listed items.
[0057] In the embodiments of the present disclosure, terms such as first, second, third, etc. may be used to describe various pieces of information, but it should be understood that these pieces of information should not be limited to these terms. These terms are merely used to distinguish between the same types of information. For example, the first piece of information can be referred to as the second piece of information, and similarly, the second piece of information can be referred to as the first piece of information, without departing from the scope of the embodiments of the present disclosure. Depending on the context, the word "if" as used herein can be interpreted as "when" or "in the case of" or "responsive to a determination."
[0058] The technical solution provided by the embodiment of the present disclosure can be applied to wireless communication between communication devices. The wireless communication between communication devices can include wireless communication between a network device and a terminal device, wireless communication between network devices and a network device, and wireless communication between a terminal device and a terminal device. In the embodiment of the present invention, the term "wireless communication" can be abbreviated to "communication", and the term "communication" can be described as "data transmission", "information transmission", or "transmission".
[0059] An embodiment of the present disclosure provides a communication system. The communication system may be a communication system using a cellular mobile communication technology. Figure 1 is a schematic configuration diagram of the communication system in the embodiment of the present disclosure. As shown in Figure 1, the communication system 10 may include a terminal device 11 and a network device 12.
[0060] In one embodiment, the above terminal device 11 may be a device that provides voice or data connectivity to a user. In some embodiments, the terminal device may be called user equipment (UE), mobile station, subscriber unit, station, or terminal equipment (TE), etc. The terminal device may be a cellular phone, a personal digital assistant (PDA), a modem, a handheld, a laptop computer, a cordless phone, a wireless local loop (WLL) station, or a pad, etc. With the development of wireless communication technology, any device that may access a communication system, communicate with the network side of the communication system, and communicate with other devices through the communication system is a terminal device in the embodiment of the present disclosure. For example, terminals and automobiles in smart transportation, household appliances in smart homes, power metering devices in smart grids, voltage monitoring devices, environmental monitoring devices, video monitoring devices in smart full networks, cash registers, etc. In the embodiment of the present disclosure, a terminal device can communicate with a network device, and a plurality of terminal devices can communicate with each other. The terminal devices may be statically fixed or mobile.
[0061] In an embodiment of the present disclosure, the above mobile device 101 may be some terminal devices with normal functions, and may also be degraded terminal devices such as NR light terminal devices, RedCap terminal devices, and extended degraded terminal devices.
[0062] In addition, two technologies, machine type communication (MTC) and narrow band internet of things (NB-IoT), have been proposed to support Internet of Things services in the 4G system. These two technologies are mainly targeted at scenes with low speeds and high latency, such as meter reading and environmental monitoring. Currently, NB-IoT can only support speeds of up to several hundred kbps (kilobits per second), and MTC can only support speeds of up to several Mbps (megabits per second). However, with the development of Internet of Things services, such as the popularization of services such as video surveillance, smart home, wearable devices, and industrial sensing monitoring, these services usually require speeds of several tens to 100 Mbps, and at the same time, there are relatively high requirements for latency. Therefore, MTC technology and NB-IoT technology in the 4G system are difficult to meet the requirements. Using this situation, we proposed requirements for designing new terminal devices to cover the above service needs in 5G NR. In the current 3rd generation partnership project (3GPP) standardization, this new type of terminal device is called a reduced capability UE (RedCap UE). Because RedCap technology is mainly targeted at medium-speed applications, RedCap UE has a maximum bandwidth of 20 MHz in the 5G FR1 frequency band. The new version of the 3GPP standard further reduces the applicable bandwidth of RedCap to 5 MHz. In this case, the terminal device can be called an enhanced reduced capability UE (eRedCap UE).
[0063] The above-mentioned network device 12 may be a device for supporting a terminal to access a communication system on the access network side, such as an evolved base station (evolved NodeB, eNB) in a 4G access technology communication system, a next generation base station (next generation nodeB, gNB) in a 5G access technology communication system, a transmission reception point (TRP), a relay node, and an access point (AP), etc.
[0064] In the NR technology, a special reference symbol is introduced, which can be called TRS / CSI-RS or TRS (TRS may be an abbreviation of TRS / CSI-RS in this specification). Based on the TRS, the terminal device can perform time and frequency synchronization. For a terminal device in a non-connected state (e.g., an idle state or a deactivated state), the terminal device can wake up as necessary to receive the TRS and perform time and frequency synchronization based on the TRS. With the assistance of the TRS, when performing time and frequency synchronization, the terminal device can reduce the number of SSB signals to be received, further shorten the wake-up time, and reduce power consumption.
[0065] Furthermore, in combination with the above communication system, the network device can have system information carried in different system messages and transmit the system messages in a broadcast manner. The system message can include a master information block (MIB) and a system information block (SIB). The SIB can also be divided into SIB1 and other SIBs (also called SIBx, where x is a positive integer equal to or greater than 2). The other SIBs can include SIB2, SIB3, SIB4, etc. The MIB carries the most necessary system information required for a terminal device to access a cell, for example, the MIB includes information such as a system frame number and / or subcarrier spacing. The SIB1 carries system information such as scheduling information, access control information, and cell selection information of the other SIBs. The other SIBs carry system information required for other functions, for example, configuration information of TRS / CSI-RS, cell reselection, positioning, emergency notification, and sidelink (SL), etc. The terminal device needs to acquire the MIB and SIB1 at all times. For the other SIBs, the terminal device can select and read system information on its own demand. The term "carry" can be explained as "bear."
[0066] In practical applications, system information (e.g., TRS configuration information) can be carried and transmitted in another SIB (i.e., SIBX). It is assumed that each TRS resource set is 65 bits or 95 bits. The number of bits of all TRS resource sets (i.e., the amount of data of the TRS resource sets) is 65×64=4160 bits or 95×64=6080 bits. Meanwhile, the amount of information data that one SIB can carry is about 2800 bits. It can be seen that the number of bits of the TRS resource set is much larger than the size that one SIB can bear. In such a case, how to realize the transmission of system information is an issue that needs to be resolved as soon as possible.
[0067] In order to solve the above problem, an embodiment of the present disclosure provides a method for transmitting system information applicable to network devices in the above communication system.
[0068] FIG. 2 is a schematic flowchart illustrating a system information transmission method performed by a network device side in an embodiment of the present disclosure. As shown in FIG. 2, the method may include the following steps 201 to 202.
[0069] At S201, the network device divides the target system information into a plurality of segments.
[0070] The target system information may include TRS configuration information, CSI-RS configuration information, etc., and of course, the target system information may also include other system information, and the embodiments of the present disclosure are not specifically limited thereto.
[0071] Exemplarily, the configuration information of the TRS and the configuration information of the CSI-RS include, but are not limited to, indication information of a pattern for transmitting the TRS, indication information of a pattern for transmitting the CSI-RS, and resource information of a transmission resource. The above pattern may be a pattern of a frequency domain resource and / or a pattern of a time domain resource, and the above transmission resource may include a frequency domain resource, a time domain resource, and a beam resource, etc.
[0072] In addition, the network device may determine whether to divide the target system information into segments for transmission, the number of segments to be divided, and the data amount of each segment based on the data amount of the target system information (i.e., the number of bits of the target system information) and the data amount that the system message can carry. Exemplarily, when the number of bits of the target system information is 4160 bits and the maximum number of bits carried in one system message is 2800 bits, the network device may determine to divide the target system information into two segments for transmission, where the number of bits of one segment is 2800 bits and the number of bits of the other segment is 1360 bits. Alternatively, the 3GPP protocol may predefine the number of segments into which the target system information is divided and the data amount of the system message carrying each segment. The network device may determine the data amount of each segment of the target system information based on the number of segments defined by the protocol and the data amount of each corresponding segment. Exemplarily, the protocol prescribes that the target system message is divided into two segments to be carried in SIB21 (2800 bits) and SIB22 (2800 bits), respectively, for transmission. The network device may have one segment with a bit number of 2800 bits, and the other segment with a bit number of 1360 bits. Of course, the network device may perform segment division on the target system information in other manners, and the embodiment of the present disclosure is not specifically limited thereto.
[0073] At S202, the network device transmits a number of segments to the terminal device.
[0074] In addition, the network device transmits a plurality of segments of the target system information by carrying them in a system message, and after receiving all or a portion of the plurality of segments, the terminal device can obtain the target system information based on the received at least one segment.
[0075] In some possible embodiments, the system message may be an SIB or an SIB-segment. The network device can send a plurality of segments to different SIBs or different SIB-segments for transmission. One segment is carried to one SIB or SIB-segment. Exemplarily, different segments can be carried to different SIBs, for example, SIB-X, SIB-Y, SIB-Z, SIB-21, SIB-22, SIB23, etc. Or, different segments can be carried to different SIB-segments, for example, SIB-segmentX, SIB-segmentY, SIB-segmentZ, etc. X, Y, Z, 21, 22, 23 are serial numbers of SIBs or SIB-segments.
[0076] Note that the SIB-segment is a segment of the SIB. That is, at the transmission position of this SIB, different groups or segments of the same SIB are transmitted multiple times, and the terminal device combines them after receiving multiple groups or segments to form a complete SIB.
[0077] In some possible embodiments, the order of multiple segments of the target system information is consistent with the order of the SIB or the SIB-segment. The network device can sequentially transmit a plurality of segments according to the order of the SIB or the SIB-segment. Exemplarily, the target system information is divided into segment 1, segment 2, and segment 3, and the network device can sequentially transmit segment 1, segment 2, and segment 3 according to the order of SIB-21, SIB-22, SIB23, or the network device can sequentially transmit segment 1, segment 2, and segment 3 according to the order of SIB-X, SIB-Y, SIB-Z (X < Y < Z).
[0078] In some possible embodiments, before S202, the above method may further include a step of the network device sending segment indication information to the terminal device, where the segment indication information indicates segment information of the target system information.
[0079] The segment information of the target system information may include segment numbers of multiple segments, segment types, etc. The segment number indicates which segment of the target system information the current segment is, and the segment type indicates whether the current segment is the last segment of the target system information or not. The value of the segment number may be an integer such as 0, 1, 2, 3, etc., and the value of the segment type may be 0 or 1.
[0080] Exemplarily, the segment number (segmentNumber) and segment type (segmentType) can be represented as follows: segmentNumber-r17 INTEGER(0..1), segmentType-r17 ENUMERATED{notLastSegment,lastSegment},
[0081] If the segment information of the current segment is (0,0), it means that the current segment is the first segment of the target system information and is not the last segment, if the segment information of the current segment is (0,1), it means that the current segment is the first segment of the target system information and is the last segment, if the segment information of the current segment is (1,1), it means that the current segment is the second segment of the target system information and is the last segment. The code point (1,0) can be reserved and not used. Of course, the above segment numbers and segment types can also be combined and coded. For example, code point 00 means that it is the first segment and is not the last segment, code point 01 means that it is the first segment and is the last segment, and code point 11 means that it is the second segment and is the last segment.
[0082] In addition, if the segment information of the current segment received by the terminal device is (0,0), the terminal device first stores the current segment and continues to wait for the next segment; if the segment information of the current segment received by the terminal device is (0,1), the terminal device first stores the current segment and obtains the target system information based on this current segment; if the segment information of the current segment received by the terminal device is (1, If 1), the terminal device determines whether the previous segment (i.e., 0 segment) has been received, and if the previous segment has been received, obtains the target system information based on the previous segment and the current segment.
[0083] In some possible embodiments, the network device can set a segment combination method of the target system information for the terminal device, so that the terminal device acquires the target system information based on different segment combination methods. Before S202, the above method further includes a step of the network device instructing the terminal device of the segment combination method of the target system information.
[0084] The segment combining scheme includes combining the target system information using all the segments or combining the target system information using some of the segments.
[0085] In some possible embodiments, the network device may instruct the terminal device of the segment combining scheme, so that the terminal device determines whether to receive all segments of the target system information based on the segment combining scheme.
[0086] In some embodiments, the network device may instruct the terminal device on the segment combination method of the target system information by sending indication information. Illustratively, the network device may make the MIB, SIB1 carry the indication information, or the network device may make the feedback information responding to the SIB request sent from the terminal device carry the indication information. Of course, the network device may make other upper layer signaling (e.g., RRC signaling) carry the indication information, but the embodiments of the present disclosure are not specifically limited thereto. Optionally, the SIB request message sent from the terminal device is carried in Msg1, and the feedback information sent from the network device is carried in Msg2.
[0087] In some other possible embodiments, the network device may instruct the terminal device to combine the target system information using the segments carried in the SIBs or SIB-segments (i.e., all segments of the target system information) by transmitting scheduling information for all SIBs or SIB-segments related to the target system information.
[0088] It should be noted that the network device transmits the scheduling information of multiple SIBs or SIB-segments to the terminal device, and the scheduling information of the multiple SIBs or SIB-segments is the scheduling information of all SIBs or SIB-segments related to the target system information. That is, by the network device transmitting the scheduling information of which SIB or SIB-segment to the terminal device, the terminal device needs to receive which SIB or SIB-segment and combine the target system information using the segments carried therein. Thus, the scheduling information of the multiple SIBs or SIB-segments not only indicates that the segment combination scheme uses all segments to combine the target system information, but also indicates the segment information (e.g., segment number, segment type) of the target system information.
[0089] In some embodiments, all segments of the target system information are carried using different SIBs (e.g., SIB-X, SIB-Y, SIB-Z, etc.). When the network device transmits the scheduling information of all SIBs related to the target system information, it implicitly indicates that the terminal device must receive these SIBs, i.e., it indicates that all segments are used to combine the target system information. After all segments are received, the terminal device combines and uses them.
[0090] For illustrative purposes, assume that the TRS configuration information is carried in two SIBs (e.g., SIB-X and SIB-Y). When the network device transmits the scheduling information of SIB-X and SIB-Y, it represents combining the target system information using all segments. The terminal device knows that it needs to receive SIB-X and SIB-Y (in this case, there is a lot of TRS content transmitted from the network device, and it performs segment transmission for the TRS configuration information), and uses them in combination.
[0091] Illustratively, it is assumed that the TRS configuration information is carried in only one SIB, and if the network device transmits only scheduling information in SIB-X, the terminal device knows that it only needs to receive SIB-X (in this case, the TRS content transmitted from the network device is small, and it is sufficient that the TRS configuration information is carried and transmitted in one SIB).
[0092] Of course, the network device and the terminal device can also determine the segment combination manner of the target system information according to the protocol specifications of 3GPP, which is not specifically limited in the embodiments of the present disclosure.
[0093] In some possible embodiments, the network device may also set a time window for the terminal device to receive the segment of the target system information, i.e. a first time length. The first time length may also be described as an available time length for the terminal device to receive the segment of the target system information. Accordingly, the above method may further include a step in which the network device indicates the first time length, for example, a number of ms (milliseconds), to the terminal device.
[0094] In addition, in one embodiment, the network device can transmit the first time length to the terminal device. Illustratively, the network device can make the MIB, SIB1 carry the first time length, or the network device can make the feedback information responding to the SIB request sent from the terminal device carry the first time length, and of course, the network device can make other upper layer signaling (e.g., RRC signaling) carry the first time length, and the embodiment of the present disclosure is not specifically limited thereto. In another embodiment, the network device and the terminal device can also determine the first time length based on the protocol specifications of 3GPP.
[0095] In some possible embodiments, when the network device transmits the segment of the target system information carried in the SIB, if the SIB carrying the segment of the target system information changes, the network device can transmit a SIB change notification (e.g., a short message) to the terminal device to inform the terminal device that the SIB has changed. After receiving the SIB change notification, the terminal device can read and obtain the updated SIB. The above method can further include a step of the network device setting a value tag of at least one SIB for the terminal device, where the value tag of the at least one SIB is used to instruct the terminal device to update the at least one SIB.
[0096] In practical applications, the network device may set value tags of multiple SIBs for the terminal device, and these value tags may be the same. In this case, the terminal device can update multiple SIBs simultaneously. That is, it means that the network performs synchronous updates for multiple SIBs, in which case the terminal knows the changes in value tags of all SIBs and performs synchronous updates of multiple SIBs. Or, the network device may set value tags of one or multiple SIBs individually for the terminal device. In this case, the terminal device may update a specific SIB or some SIBs individually. In this way, for SIBs that have not been changed, the terminal does not need to update, which has the advantage of saving decoding overhead. Of course, the network device may set value tags of SIBs using other methods, and the embodiments of the present disclosure are not specifically limited thereto.
[0097] Illustratively, updates to one SIB do not result in changes to other SIBs, but the availability of resources in other SIBs may still be affected and may be withheld or unavailable.
[0098] For illustrative purposes, assume that the configuration information of the TRS is carried in two SIBs, e.g., SIB-X and SIBY, respectively. If the network device only sends an update (i.e., a value tag) for SIB-X, the terminal device is not affected by the SIB-X update after receiving the system message notification and continues to use the resources of the TRS indicated by SIB-Y.
[0099] Exemplarily, assume that the configuration information of the TRS is carried in two SIBs, for example, SIB-X and SIBY, respectively. If the network device only sends an update (i.e., a value tag) of SIB-X, the terminal device will not use and reserve the resources of the TRS indicated by SIB-Y after receiving the system message notification, and will use the resources of the TRS indicated by SIB-Y after obtaining the updated SIB-X. Alternatively, after the system information is updated, the terminal device can obtain the updated configuration information of the TRS and then wait for the network device to send an availability indication of the TRS.
[0100] In an embodiment of the present disclosure, segment transmission is performed for target system information, thereby avoiding the situation where the target system information cannot be transmitted due to being too large to be carried in a single SIB, thereby improving the transmission reliability of the target system information.
[0101] Based on the same inventive idea, an embodiment of the present disclosure provides a method for transmitting system information, which can be applied to a terminal device of the above communication system.
[0102] FIG. 3 is a schematic flowchart illustrating a method for transmitting system information at a terminal device side in an embodiment of the present disclosure. Referring to FIG. 3, the method may include the following steps S301 to S302.
[0103] In S301, a terminal device obtains at least one segment from a network device.
[0104] At least one segment is associated with target system information.
[0105] It should be noted that the network device transmits segments of the target system information to the terminal in the above S201-S202, and the terminal device receives at least one segment, which may be all or some of the segments of the target system information.
[0106] In some possible embodiments, the target system information includes configuration information for TRS / CSI-RS.
[0107] At S302, the terminal device obtains target system information based on the at least one segment.
[0108] In some possible embodiments, the network device transmits segments of the target system information carried in SIBs or SIB-segments, one segment being carried in one SIB or SIB-segment, and the terminal device first receives at least one SIB or SIB-segment and further obtains the target system information based on the segments carried in these SIBs or SIB-segments.
[0109] Illustratively, different segments may be carried in different SIBs, e.g., SIB-X, SIB-Y, SIB-Z, SIB-21, SIB-22, SIB23, etc. Or, different segments may be carried in different SIB-segments, e.g., SIB-segmentX, SIB-segmentY, SIB-segmentZ, etc., where X, Y, Z, 21, 22, 23 are serial numbers of the SIBs or SIB-segments.
[0110] In some possible embodiments, the order of the plurality of segments of the target system information matches the order of the SIB or the order of the SIB-segment. The network device can sequentially transmit the plurality of segments according to the order of the SIB or the SIB-segment. Exemplarily, the system information is divided into segment 1, segment 2, and segment 3, and the network device can sequentially transmit segment 1, segment 2, and segment 3 according to the order of SIB-21, SIB-22, SIB23, or the network device can sequentially transmit segment 1, segment 2, and segment 3 according to the order of SIB-X, SIB-Y, SIB-Z (X < Y < Z).
[0111] In one embodiment, when there are multiple SIBs or SIB-segments, the terminal device can first combine the multiple SIBs or SIB-segments, and then analyze the combined SIB or SIB-segment to obtain the target system information. In this way, the number of times of analyzing the information can be reduced, the processing flow can be simplified, the processing time can be shortened, and furthermore, the acquisition efficiency of the target system information can be improved.
[0112] In another embodiment, when there are multiple SIBs or SIB-segments, the terminal device can first analyze each SIB or SIB-segment to obtain the multiple subgroups carried therein, and then combine the multiple subgroups to obtain the target system information. In this way, each segment can be accurately analyzed to improve the success rate of obtaining the target system information, and furthermore, the transmission reliability of the system information can be improved.
[0113] Alternatively, after receiving each SIB or SIB-segment, the terminal device can parse the SIB or SIB-segment to obtain the corresponding segment, or the terminal device can first store the received SIB or SIB-segment, and after receiving multiple SIBs or SIB-segments, parse the multiple SIBs or SIB-segments one by one to obtain the corresponding segments.
[0114] In some possible embodiments, the network device may indicate the segment information of the target system information to the terminal device before transmitting the segment. The above method further includes a step of the terminal device receiving segment indication information from the network device, where the segment indication information indicates the segment information of the target system information.
[0115] The segment information of the target system information may include segment numbers of multiple segments, segment types, etc. The segment number indicates which segment of the target system information the current segment is, and the segment type indicates whether the current segment is the last segment of the target system information or not. The value of the segment number may be an integer such as 0, 1, 2, 3, etc., and the value of the segment type may be 0 or 1.
[0116] Exemplarily, the segment number (segmentNumber) and segment type (segmentType) can be represented as follows: segmentNumber-r17 INTEGER (0..1), segmentType-r17 ENUMERATED {notLastSegment, lastSegment},
[0117] If the segment information of the current segment is (0,0), it means that the current segment is the first segment of the target system information and is not the last segment, if the segment information of the current segment is (0,1), it means that the current segment is the first segment of the target system information and is the last segment, if the segment information of the current segment is (1,1), it means that the current segment is the second segment of the target system information and is the last segment. (1,0) is not used and can be reserved.
[0118] Of course, any combination of the above segment numbers and segment types can be coded: for example, code point 00 means the first but not the last segment, code point 01 means the first but not the last segment, code point 11 means the second but not the last segment, etc.
[0119] Of course, the terminal device can also determine the segment information of the target system information based on the protocol specifications of 3GPP, and the embodiments of the present disclosure are not specifically limited thereto.
[0120] Furthermore, if the segment information of the current segment received by the terminal device is (0,0), the terminal device first stores the current segment and continues to wait for the next segment; if the segment information of the current segment received by the terminal device is (0,1), the terminal device first stores the current segment and obtains target system information based on the current segment; if the segment information of the current segment received by the terminal device is (1,1), the terminal device determines whether the previous segment has been received, and if the previous segment has been received, obtains target system information based on the previous segment and the current segment.
[0121] In some possible embodiments, the terminal device may determine a segment combination method of the target system information based on a setting of a network device or a protocol provision of 3GPP, so that the terminal device acquires the target system information based on different segment combination methods. Before S301, the above method further includes a step of the terminal device determining a segment combination method of the target system information.
[0122] The segment combining scheme includes combining the target system information using all the segments or combining the target system information using some of the segments.
[0123] In addition, the terminal device can determine whether to receive all segments of the target system information based on the instruction of the network device or the segment combination method specified in the 3GPP protocol. If the segment combination method specified by the network device or specified in the protocol is to combine the target system information using all segments, the terminal device needs to wait until all segments of the target system information are received and then perform segment combination to obtain the target system information. Or, if the segment combination method specified by the network device or specified in the protocol is to combine the target system information using some segments, the terminal device does not need to wait until all segments of the target system information are received and can perform segment combination after receiving some segments to obtain the target system information.
[0124] In some possible embodiments, the network device can instruct the terminal device to use a segment combination scheme of the target system information by sending indication information. Illustratively, the network device can make the MIB, SIB1 carry the indication information, or the network device can make the feedback information responding to the SIB request sent from the terminal device carry the indication information, and of course, the network device can make other upper layer signaling (e.g., RRC signaling) carry the indication information, and the embodiment of the present disclosure is not specifically limited thereto. Optionally, the SIB request message sent from the terminal device is carried in Msg1, and the feedback information sent from the network device is carried in Msg2. After receiving the indication information, the terminal device determines a segment combination scheme, and combines and uses at least one received segment according to the segment combination scheme.
[0125] In some other possible embodiments, the network device may also instruct the terminal device on the segment combination scheme of the target system information by transmitting scheduling information of all SIBs or SIB-segments related to the target system information. The above method further includes a step of the terminal device receiving scheduling information of a plurality of SIBs or SIB-segments from the network device, and a step of the terminal device combining the target system information using segments carried in the plurality of SIBs or SIB-segments.
[0126] In addition, the network device transmits the scheduling information of multiple SIBs or SIB-segments to the terminal device. Here, the scheduling information of the multiple SIBs or SIB-segments is the scheduling information of all SIBs or SIB-segments related to the target system information. That is, by the network device transmitting the scheduling information of which SIB or SIB-segment to the terminal device, the terminal device receives which SIB or SIB-segment and combines the target system information using the segments carried therein. Thus, the scheduling information of the multiple SIBs or SIB-segments not only indicates that the segment combination scheme uses all segments to combine the target system information, but also indicates the segment information (e.g., segment number, segment type) of the target system information.
[0127] In one embodiment, all segments of the target system information are carried using different SIBs (e.g., SIB-X, SIB-Y, SIB-Z, etc.). When the network device transmits the scheduling information of all SIBs related to the target system information, it implicitly indicates that the terminal device must receive these SIBs, i.e., it indicates that all segments are used to combine the target system information. After all segments are received, the terminal device combines and uses them.
[0128] For illustrative purposes, assume that the TRS configuration information is carried in two SIBs (e.g., SIB-X and SIB-Y). When the network device transmits the scheduling information of SIB-X and SIB-Y, it represents combining the target system information using all segments. The terminal device knows that it needs to receive SIB-X and SIB-Y (in this case, there is a lot of TRS content transmitted from the network device, and it performs segment transmission for the TRS configuration information).
[0129] In some possible embodiments, in response to the terminal device determining to combine the target system information using all segments, the above method further includes a step of the terminal device determining that the current segment is the last segment of the target system information, and accordingly, S302 further includes a step of the terminal device combining the target system information using at least one segment.
[0130] In addition, after the terminal device determines that the segment combination method is to use all the segments combined target system information, the terminal device judges whether the currently received segment (i.e., the current segment) is the last segment of the target system information. If yes, the terminal device recognizes that all the segments of the target system information have been received, and combines and uses all the subsequently received segments. If no, the terminal device recognizes that all the segments of the target system information have not yet been received, and stores the current segment, and continues to wait for the reception of the next segment. In practical application, the terminal device needs to perform the above judgment for each received segment to determine whether all the segments of the target system information have been received.
[0131] In some possible embodiments, the above determination process can also use a first time length as a constraint. S302 can include the steps of: a terminal device receiving at least one segment within a first time length (see above example for details); and, when the first time length expires, the terminal device determining that the at least one segment is all segments of the target system information and combining the target system information using the at least one segment; or, when the first time length expires, the terminal device determining that the at least one segment is not all segments of the target system information and discarding the at least one segment.
[0132] It should be noted that the terminal device can determine the first time length based on the instruction of the network device or the protocol specification of 3GPP. Then, the terminal device receives at least one segment within the first time length. When the first time length expires, the terminal device judges whether the received at least one segment is all segments of the target system information. If yes, the terminal device uses all the received segments in combination; if no, the terminal device recognizes that the system message has not been received and discards the received at least one segment.
[0133] In some possible embodiments, in response to the terminal device determining to combine the target system information using some of the segments, S302 may include a step in which the terminal device receives at least one segment within a first length of time, and a step in which the terminal device combines the target system information using the at least one segment upon expiration of the first length of time.
[0134] It is noted that the terminal device can determine the first time length based on the instruction of the network device or the protocol specification of 3GPP.The terminal device then receives at least one segment within the first time length.When the first time length expires, the terminal can directly combine and use the received at least one segment.
[0135] In an embodiment of the present disclosure, segment transmission is performed for target system information, thereby avoiding the situation where the target system information cannot be transmitted due to being too large to be carried in a single SIB, thereby improving the transmission reliability of the target system information.
[0136] Based on the same inventive concept, the embodiment of the present disclosure further provides a communication device, which may be a network device or a chip or system-on-chip in the network device in a communication system, or a functional module for implementing the method of each of the above embodiments in the network device.

[0143] In some possible embodiments, the first transmission module 42 further indicates a first length of time to the terminal device, the first length of time being an available length of time for the terminal device to receive the segment of the target system information.
[0144] In some possible embodiments, the first processing module 41 further sets a value tag of at least one SIB for the terminal device, the value tag being used to instruct the terminal device to update the at least one SIB.

These hardware or software include one or more modules corresponding to the above functions. FIG. 5 is a schematic configuration diagram of another communication device in an embodiment of the present disclosure. Referring to FIG. 5, the communication device 50 includes a second transmission module 51 for acquiring at least one segment from a network device, where the at least one segment is associated with target system information, and a second processing module 52 for acquiring the target system information based on the at least one segment.
[0149] In some possible embodiments, the target system information includes configuration information for TRS / CSI-RS.
[0150] In some possible embodiments, the second transmission module 52 receives at least one segment carried in a SIB or a SIB-segment.
[0151] In some possible embodiments, the order of at least one segment matches the order of at least one SIB or SIB-segment.
