Description

Background Art

[0002] DSS (Dynamic Spectrum Sharing) is a technology that dynamically shares the same spectrum between different network standards. It is currently used to dynamically share spectrum between the fourth generation mobile communication technology (Fourth Generation, referred to as 4G, also known as LTE (Long-Term Evolution)) and the fifth generation mobile communication technology (Fifth Generation, referred to as 5G) according to business conditions, providing support for the smooth transition from 4G to 5G.

[0003] In the DSS scenario, since the LTE cell reference signal (CRS) conflicts with the NR (NewRadio, a 5G new wireless access technology) PDSCH (Physical Downlink Shared Channel), it is necessary to rate match the RE (Resource element) where the CRS is located on the NR side. However, with the development of communication technology, sometimes the LTE spectrum bandwidth exceeds the NR spectrum bandwidth range, resulting in CRS rate matching errors and failure to meet communication requirements.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0035] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0036] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0037] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0038] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0039] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0040] For ease of understanding, several terms involved in the present disclosure are explained below:

[0041] DSS (Dynamic Spectrum Sharing): is a technology that dynamically shares the same spectrum between different network standards. It is currently used to dynamically share spectrum between 4G and 5G based on business conditions, providing support for a smooth transition from 4G to 5G.

[0042] CRS (Cell Reference Signal): A pilot reference signal in the LTE system, used for channel measurement and estimation.

[0043] CRS rate matching: In the DSS scenario, since the LTE CRS signal will conflict with the NR's PDSCH, it is necessary to perform rate matching on the RE (Resource element) where the CRS is located on the NR side, that is, not scheduling PDSCH on the RE where the CRS is located, in order to resolve the conflict. This is the most basic function that must be possessed in the DSS scenario. If this function cannot be successfully implemented, DSS is considered unavailable.

[0044] RE: The smallest unit of time-frequency resources in a wireless network, which occupies one subcarrier in the frequency domain and one OFDM (Orthogonal Frequency Division Multiplexing, a multi-carrier modulation technology) symbol in the time domain. CRS is configured in units of RE.

[0045] Point A (NR access point location): NR benchmark reference point, as the common reference point of the resource block grid, the actual configuration is generally consistent with the starting point of the NR maximum bandwidth.

[0046] BWP (Bandwidth Part): BWP is a combination of multiple consecutive RBs (Resource Blocks) within a carrier. The bandwidth configuration of each BWP can be different to accommodate different types of terminals and service types.

[0047] In related technologies, DSS is a technical method for different network standards to dynamically share spectrum resources on the same spectrum. DSS technology is mainly used between 4G and 5G. Since 4G and 5G need to coexist in the same spectrum, it is technically necessary to solve the signal conflict problem between 4G and 5G. The most critical one is the rate matching function for LTE CRS on the NR side (3GPP TS 38.214, clause 5.1.4.2, a standard). The network equipment can send a broadcast message (for example, RateMatchPatternLTE-CRS field) to the terminal. The NR terminal determines the spectrum bandwidth range of LTE and the specific frequency position of the RE occupied by CRS through the broadcast message, and then performs rate matching for LTE CRS.

[0048] The inventors found that the standards and network equipment implementations in the related art all assume that the LTE spectrum bandwidth completely overlaps with the NR spectrum bandwidth or is completely included in the NR spectrum bandwidth (e.g. Figure 1However, with the development of technology, there may be a situation where the LTE spectrum bandwidth exceeds the NR spectrum bandwidth range. If the calculation is still based on the above assumptions, the LTE start position or end position will exceed the NR bandwidth range, which is beyond the expectations of the terminal algorithm design, resulting in the terminal calculating the wrong CRS frequency position and NR rate matching errors (currently, some terminals have discovered such situations) (such as Figure 2 , 3 , 4), therefore, the present disclosure proposes a method for solving the above problems.

[0049] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0050] Figure 5 A schematic diagram of a CRS rate matching system structure in an embodiment of the present disclosure is shown. The system can apply the CRS rate matching method or CRS rate matching device in each embodiment of the present disclosure.

[0051] like Figure 5 As shown, the system architecture may include a terminal 501 and a network device 502 .

[0052] The terminal 501 and the network device 502 are connected to each other through a network, which may be a wired network or a wireless network.

[0053] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocol. The network is usually the Internet, but it can also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged through the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec) can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can also be used to replace or supplement the above data communication technologies.

[0054] The terminal 501 may be any electronic device, including but not limited to a smart phone, a tablet computer, a laptop computer, a desktop computer, a wearable device, an augmented reality device, a virtual reality device, etc.

[0055] Optionally, the client of the application installed in different terminals 501 is the same, or the client of the same type of application based on different operating systems. Based on the different terminal platforms, the specific form of the client of the application can also be different, for example, the application client can be a mobile client, a PC client, etc.

[0056] The network device 502 is used to implement network communication, such as a switch, a base station (such as a gNB (5G base station)), a centralized unit (CU) and a distributed unit (DU). The network device 102 can send a broadcast message to the terminal 101, for example, a broadcast system message (such as an RRC (Radio Resource Control, a control channel in wireless communication) message), but the present disclosure is not limited thereto.

[0057] Those skilled in the art will know that Figure 5The number of terminals and network devices in the embodiment is only illustrative, and any number of terminals and network devices may be provided according to actual needs. The embodiments of the present disclosure are not limited to this. In addition, the present disclosure is applied in the field of communications and is applicable to any DSS scenario. For example, it can be applied in scenarios where unequal bandwidth DSS networks and LTE exceeds the NR frequency range.

[0058] The present exemplary implementation is described in detail below with reference to the accompanying drawings and embodiments.

[0059] First, a CRS rate matching method is provided in an embodiment of the present disclosure, and the method can be executed by any electronic device with computing and processing capabilities.

[0060] Figure 6 A flow chart of a method for matching a cell reference signal CRS rate in an embodiment of the present disclosure is shown as follows: Figure 6 As shown, the CRS rate matching method provided in the embodiment of the present disclosure may include the following S601 to S605.

[0061] S601: Receive a broadcast message sent by a network device.

[0062] The broadcast message is a message sent by a network device to a terminal, which includes parameter information for instructing the terminal to perform CRS rate matching. The broadcast message may be an RRC message or a broadcast system message, but the present disclosure is not limited thereto. For example, the broadcast system message is a message including a RateMatchPatternLTE-CRS field.

[0063] S602: Obtain the starting position and the ending position of the spectrum bandwidth of the fourth generation mobile communication technology LTE according to the broadcast message.

[0064] In an exemplary embodiment, the broadcast message includes the NR access point location, the LTE downlink carrier frequency and the LTE downlink carrier bandwidth; wherein, according to the broadcast message, the starting position and the ending position of the spectrum bandwidth of the fourth generation mobile communication technology LTE are obtained, which may include the following steps A1 and A2.

[0065] Step A1, obtain the LTE center frequency position according to the NR access point position and the LTE downlink carrier frequency.

[0066] NR access point (NR pointA) refers to a term in the 5G (fifth generation) wireless communication system. NR stands for New Radio, which is the air interface of 5G. "Point A" refers to an interface point in the radio access network (RAN). At NR Point A, a wireless connection is established between the user equipment (UE) and the 5G base station (gNB) for data transmission and communication.

[0067] LTE downlink carrier frequency (carrierFreqDL) is a parameter in LTE. In the LTE system, wireless signals are transmitted through different carrier frequencies, and "carrierFreqDL" specifies the carrier frequency used for downlink data transmission. This parameter is usually measured in Hertz (Hz) and is used to determine the transmission frequency of downlink data in the LTE system.

[0068] In the present disclosure, Figure 1 As shown, the LTE center frequency point position is calculated by the NR pointA position (the same as the NR starting position) and carrierFreqDL. Exemplarily, the LTE center frequency point position is the sum of the NR pointA position and the LTE carrierFreqDL.

[0069] Step A2: Obtain the starting position and ending position of the LTE spectrum bandwidth according to the LTE center frequency position and the LTE downlink carrier bandwidth.

[0070] LTE downlink carrier bandwidth is a parameter in LTE, which indicates the downlink carrier bandwidth.

[0071] In the embodiment of the present disclosure, the starting position of the LTE spectrum bandwidth is calculated by the following formula 1.

[0072]

[0073] Among them, LS is the starting position of the LTE spectrum bandwidth; P is the LTE center frequency position; C is the LTE downlink carrier bandwidth.

[0074] The end position of the LTE spectrum bandwidth is calculated by the following formula 2.

[0075]

[0076] Among them, LT is the end position of the LTE spectrum bandwidth; P is the LTE center frequency position; C is the LTE downlink carrier bandwidth.

[0077] The disclosed embodiment can calculate the starting position and ending position of the LTE spectrum bandwidth through the NR access point position, the LTE downlink carrier frequency and the LTE downlink carrier bandwidth, so as to prepare for determining whether the LTE spectrum bandwidth is included in the NR spectrum bandwidth.

[0078] S603, obtaining the starting position and the ending position of the spectrum bandwidth of the fifth generation mobile communication technology NR.

[0079] In the embodiments of the present disclosure, there is no limitation on how to obtain the starting position and the ending position of the NR spectrum bandwidth. For example, the starting position and the ending position of the NR spectrum bandwidth can be obtained through a broadcast message; it can also be obtained through an RRC message; it can also be obtained through the terminal's own usage parameters.

[0080] Exemplarily, the starting position and the ending position of the NR spectrum bandwidth are obtained through a broadcast message. It should be noted that the broadcast message may be the same as the broadcast message in S601, or may be different from the broadcast message in S601. For example, the broadcast message is the same as the broadcast message in S601. For another example, the broadcast message is a different broadcast message from the broadcast message in S601.

[0081] S604: Adjust the starting position and ending position of the LTE spectrum bandwidth by the starting position and ending position of the NR spectrum bandwidth so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth.

[0082] In the embodiments of the present disclosure, the LTE spectrum bandwidth is included in the NR spectrum bandwidth, including the case where the LTE spectrum bandwidth is the same as the NR spectrum bandwidth. The starting position and the ending position of the LTE spectrum bandwidth are adjusted by the starting position and the ending position of the NR spectrum bandwidth, thereby ensuring that the LTE spectrum bandwidth is included in the NR spectrum bandwidth, thereby ensuring that the CRS rate matching is correct.

[0083] S605: Perform CRS rate matching according to the adjusted start position and end position of the LTE spectrum bandwidth.

[0084] The related technology implements CRS rate matching based on the complete overlap of the LTE spectrum bandwidth and the NR spectrum bandwidth in the DSS or is completely contained in the NR bandwidth. However, if the LTE spectrum bandwidth exceeds the NR spectrum bandwidth range, there will be CRS rate matching errors caused by early terminal design problems. The present disclosure fully considers various DSS situations, is more generally adaptable than related technologies, and will not have the above problems. It should be noted that the starting position and ending position of the LTE spectrum bandwidth adjusted in the present disclosure can be used for CRS rate matching in 5G. In 4G, the starting position and ending position of the LTE spectrum bandwidth before adjustment can be used for CRS rate matching, or the starting position and ending position of the LTE spectrum bandwidth after adjustment can be used for CRS rate matching, but the present disclosure is not limited to this.

[0085] In the embodiment of the present disclosure, the terminal receives a broadcast message sent by a network device, and calculates the starting position and the ending position of the LTE spectrum bandwidth according to the broadcast message, and adjusts the starting position and the ending position of the LTE spectrum bandwidth according to the starting position and the ending position of the NR spectrum bandwidth, so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth, thereby ensuring correct CRS rate matching.

[0086] The following describes how to adjust the starting position and the ending position of the LTE spectrum bandwidth.

[0087] In an exemplary embodiment, the starting position and the ending position of the LTE spectrum bandwidth are adjusted by the starting position and the ending position of the NR spectrum bandwidth so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth, which may include: judging the size relationship between the starting position of the NR spectrum bandwidth and the starting position of the LTE spectrum bandwidth; if the starting position of the LTE spectrum bandwidth is smaller than the starting position of the NR spectrum bandwidth, replacing the starting position of the LTE spectrum bandwidth with the starting position of the NR spectrum bandwidth, so that the adjusted starting position of the LTE spectrum bandwidth is included in the NR spectrum bandwidth; judging the size relationship between the ending position of the NR spectrum bandwidth and the ending position of the LTE spectrum bandwidth; if the ending position of the LTE spectrum bandwidth is larger than the ending position of the NR spectrum bandwidth, replacing the ending position of the LTE spectrum bandwidth with the ending position of the NR spectrum bandwidth, so that the adjusted ending position of the LTE spectrum bandwidth is included in the NR spectrum bandwidth.

[0088] The embodiment of the present disclosure may encounter four situations through the above judgment.

[0089] The first case, such as Figure 1 As shown in FIG. 1 , the LTE spectrum bandwidth is included in the NR spectrum bandwidth. For the first case, there is no need to adjust the LTE spectrum bandwidth.

[0090] The second case, such as Figure 2 As shown in FIG. 1 , the starting position of the LTE spectrum bandwidth is smaller than the starting position of the NR spectrum bandwidth. For the second case, the starting position of the LTE spectrum bandwidth is replaced by the starting position of the NR spectrum bandwidth, so that the starting position of the adjusted LTE spectrum bandwidth is included in the NR spectrum bandwidth. The adjusted schematic diagram is shown in FIG. Figure 7 As shown in the diagram on the right. It should be noted that Figure 7 The diagram on the left is the diagram before adjustment ( Figure 2 ).

[0091] The third case, such as Figure 3As shown in FIG. 1 , the end position of the LTE spectrum bandwidth is greater than the end position of the NR spectrum bandwidth. For the third case, the end position of the LTE spectrum bandwidth is replaced by the end position of the NR spectrum bandwidth, so that the end position of the adjusted LTE spectrum bandwidth is included in the NR spectrum bandwidth. The adjusted schematic diagram is shown in FIG. Figure 8 As shown in the diagram on the right. It should be noted that Figure 8 The diagram on the left is the diagram before adjustment ( Figure 3 ).

[0092] The fourth case, such as Figure 4 As shown in FIG. 1 , the starting position of the LTE spectrum bandwidth is smaller than the starting position of the NR spectrum bandwidth, and the ending position of the LTE spectrum bandwidth is larger than the ending position of the NR spectrum bandwidth. For the fourth case, the starting position of the LTE spectrum bandwidth is replaced by the starting position of the NR spectrum bandwidth, and the ending position of the LTE spectrum bandwidth is replaced by the ending position of the NR spectrum bandwidth, so that the starting position and the ending position of the LTE spectrum bandwidth after adjustment are included in the NR spectrum bandwidth. The adjusted schematic diagram is shown in FIG. Fig. 9 As shown in the diagram on the right. It should be noted that Fig. 9 The diagram on the left is the diagram before adjustment ( Figure 4 ).

[0093] For example, Fig.10 As shown, the CRS rate matching method provided in the embodiment of the present disclosure may include the following S1001 to S1008.

[0094] S1001, the terminal obtains RRC information, wherein the RRC information includes the NR access point location, LTE downlink carrier frequency and LTE downlink carrier bandwidth.

[0095] S1002, calculate the LTE center frequency position through the NR access point position and the LTE downlink carrier frequency. How to calculate the LTE center frequency position has been described in step A1 and will not be repeated here.

[0096] S1003, calculate the starting position and ending position of the LTE spectrum bandwidth by using the LTE center frequency position and the LTE downlink carrier bandwidth. How to calculate the starting position and ending position of the LTE spectrum bandwidth has been described in step A2 and will not be repeated here.

[0097] S1004, determine whether the starting position of the LTE spectrum bandwidth is smaller than the starting position of the NR spectrum bandwidth. If so, execute S1005; if greater than or equal to, execute S1006.

[0098] S1005, the starting position of the NR spectrum bandwidth replaces the starting position of the LTE spectrum bandwidth.

[0099] S1006, the end position of the LTE spectrum bandwidth is greater than the end position of the NR spectrum bandwidth. If so, execute S1007. If less than or equal to, execute S1008. It should be noted that the embodiment of the present disclosure does not limit the execution order of S1004 and S1006. As long as the start position and end position of the adjusted LTE spectrum bandwidth are included in the NR spectrum bandwidth, any adjustment is acceptable.

[0100] S1007, the end position of the NR spectrum bandwidth replaces the end position of the LTE spectrum bandwidth.

[0101] S1008, establish the upper and lower boundary ranges of CRS rate matching (the start and end positions of the adjusted LTE spectrum bandwidth). It should be noted that the specific CRS RE frequency position is determined for NR rate matching based on the adjusted start and end positions of LTE and v-Shift (offset value). v-Shift is described in 3GPP standard TS 38.331 (a communication standard) and LTE specifications (TS 38.214

[19] , Section 5.1.4.2), which is a parameter used to adjust the CRS position. CRS is a special reference signal used for receiver timing and frequency synchronization in LTE. By applying v-shift, the position of CRS can be offset during the rate matching process.

[0102] The disclosed embodiment replaces the starting position of the LTE spectrum bandwidth that is smaller than the NR starting position with the starting position of the NR spectrum bandwidth, and replaces the ending position of the LTE spectrum bandwidth that is larger than the NR ending position with the ending position of the NR spectrum bandwidth, thereby ensuring that the LTE spectrum bandwidth is located within the NR spectrum bandwidth with the maximum width, thereby making more spectrum resources available, and further improving the communication speed of downlink data while ensuring correct CRS rate matching.

[0103] In another exemplary embodiment, before adjusting the starting position and ending position of the LTE spectrum bandwidth through the starting position and ending position of the NR spectrum bandwidth, the method may also include: determining whether the LTE spectrum bandwidth is included in the NR spectrum bandwidth; if not, adjusting the starting position and ending position of the LTE spectrum bandwidth through the starting position and ending position of the NR spectrum bandwidth so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth.

[0104] The embodiments of the present disclosure do not limit how to determine whether the LTE spectrum bandwidth is included in the NR spectrum bandwidth. For example, the judgment can be made by the downlink carrier bandwidth of the LTE spectrum bandwidth, the starting position of the LTE spectrum bandwidth, the NR access point position, and the downlink carrier bandwidth of the NR spectrum bandwidth. If not included, execute S604. If included, perform CRS rate matching according to the starting position and the ending position of the LTE spectrum bandwidth.

[0105] It should be noted that the present disclosure may not perform the judgment of whether the LTE spectrum bandwidth is included in the NR spectrum bandwidth (not perform this exemplary embodiment), and only perform S604. As for how to choose, it can be selected according to the specific application scenario and actual application experience.

[0106] The embodiment of the present disclosure first determines whether the LTE spectrum bandwidth is included in the NR spectrum bandwidth. If so, the starting position and the ending position of the LTE spectrum bandwidth are adjusted. If not, no adjustment is made, so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth, thereby ensuring correct CRS rate matching.

[0107] The following describes the situation where the starting position or the ending position of the NR spectrum bandwidth changes.

[0108] Sometimes, the starting or ending position of the NR spectrum bandwidth may change due to switching operations. For example, NR may switch BWP later, resulting in a similar Figure 4 To determine the effect, it is necessary to re-compare the starting and ending positions of the LTE spectrum bandwidth and the NR spectrum bandwidth.

[0109] In an exemplary embodiment, after performing CRS rate matching according to the adjusted start position and end position of the LTE spectrum bandwidth, the method may further include the following steps B1 and B2.

[0110] Step B1, determine whether the starting position and the ending position of the NR spectrum bandwidth have changed.

[0111] In one embodiment, determining whether the starting position and the ending position of the NR spectrum bandwidth have changed may include the following steps C1 to C3.

[0112] Step C1, reacquire the starting position and ending position of the NR spectrum bandwidth.

[0113] How to obtain the starting position and the ending position of the NR spectrum bandwidth is the same as that in S603 and will not be described in detail here.

[0114] Step C2, by re-obtaining the starting position and the ending position of the NR spectrum bandwidth and comparing them with the starting position and the ending position of the NR spectrum bandwidth obtained last time, a comparison result is obtained.

[0115] In the embodiment of the present disclosure, the starting position and the ending position of the NR spectrum bandwidth obtained last time may be the starting position and the ending position of the NR spectrum bandwidth obtained in S603, or may be the starting position and the ending position of the NR spectrum bandwidth re-obtained in the last step C1.

[0116] In the disclosed embodiment, the starting position for reacquiring the NR spectrum bandwidth is the first starting position, the ending position for reacquiring the NR spectrum bandwidth is the first ending position, the starting position of the NR spectrum bandwidth acquired last time is the second starting position, and the ending position of the NR spectrum bandwidth acquired last time is the second ending position. It is determined whether the first starting position is equal to the second starting position to obtain a first comparison result. It is determined whether the first ending position is equal to the second ending position to obtain a second comparison result.

[0117] Step C3: determine whether the starting position and the ending position of the NR spectrum bandwidth have changed according to the comparison result.

[0118] If the first comparison result and the second comparison result are both equal, it means that the starting position and the ending position of the NR spectrum bandwidth have not changed. If the first comparison result is not equal or the second comparison result is not equal, it means that the starting position and the ending position of the NR spectrum bandwidth have changed.

[0119] The embodiment of the present disclosure determines whether the starting position and the ending position of the NR spectrum bandwidth have changed by re-acquiring the starting position and the ending position of the NR spectrum bandwidth, and can timely adjust the LTE spectrum bandwidth according to the change of the NR spectrum bandwidth, so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth, ensuring correct CRS rate matching.

[0120] In another embodiment, determining whether the starting position and the ending position of the NR spectrum bandwidth have changed may include the following steps D1 to D4.

[0121] Step D1, reacquire the starting position and ending position of the NR spectrum bandwidth.

[0122] How to obtain the starting position and the ending position of the NR spectrum bandwidth is the same as that in S603 and will not be described in detail here.

[0123] Step D2, obtaining the first carrier bandwidth of the NR spectrum bandwidth based on the reacquired starting position and ending position of the NR spectrum bandwidth.

[0124] In the embodiment of the present disclosure, the first carrier bandwidth is the difference between the end position of the NR spectrum bandwidth and the start position of the NR spectrum bandwidth.

[0125] Step D3, obtaining the second carrier bandwidth of the NR spectrum bandwidth according to the starting position and the ending position of the NR spectrum bandwidth obtained last time.

[0126] In the embodiment of the present disclosure, the second carrier bandwidth is the difference between the end position of the NR spectrum bandwidth obtained last time and the starting position of the NR spectrum bandwidth obtained last time.

[0127] Step D4: Determine whether the starting position and the ending position of the NR spectrum bandwidth have changed based on the first carrier bandwidth, the second carrier bandwidth, the starting position of the reacquired NR spectrum bandwidth, and the starting position of the last acquired NR spectrum bandwidth.

[0128] If the first carrier bandwidth is equal to the second carrier bandwidth, and the starting position of the reacquired NR spectrum bandwidth is equal to the starting position of the last acquired NR spectrum bandwidth, the starting position and the ending position of the NR spectrum bandwidth are not changed. If the first carrier bandwidth is not equal to the second carrier bandwidth, or the starting position of the reacquired NR spectrum bandwidth is not equal to the starting position of the last acquired NR spectrum bandwidth, the starting position and the ending position of the NR spectrum bandwidth are changed.

[0129] The embodiment of the present disclosure determines whether the starting position and the ending position of the NR spectrum bandwidth have changed by re-acquiring the starting position and the ending position of the NR spectrum bandwidth, and can timely adjust the LTE spectrum bandwidth according to the change of the NR spectrum bandwidth, so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth, ensuring correct CRS rate matching.

[0130] Step B2: If a change occurs, the starting position and the ending position of the LTE spectrum bandwidth are adjusted by the starting position and the ending position of the NR spectrum bandwidth so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth.

[0131] It should be noted that if the NR spectrum bandwidth subsequently switches to a small BWP, such as Figure 4 If the effect is achieved, the starting and ending positions of the LTE spectrum bandwidth and the starting and ending positions of the NR spectrum bandwidth are re-compared. At this time, the CRS rate matching range is from the starting position of the NR spectrum bandwidth to the ending position of the NR spectrum bandwidth.

[0132] The disclosed embodiment timely adjusts the LTE spectrum bandwidth according to the change of the NR spectrum bandwidth, so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth, ensuring correct CRS rate matching.

[0133] Based on the same inventive concept, a CRS rate matching device is also provided in the embodiments of the present disclosure, as described in the following embodiments. Since the principle of solving the problem in the device embodiment is similar to that in the above method embodiment, the implementation of the device embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be repeated.

[0136] In one embodiment, the calculation module 112 can also be used to determine whether the LTE spectrum bandwidth is included in the NR spectrum bandwidth; if not, the starting position and the ending position of the LTE spectrum bandwidth are adjusted by the starting position and the ending position of the NR spectrum bandwidth so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth.

[0137] In one embodiment, if included, CRS rate matching is performed according to the starting position and the ending position of the LTE spectrum bandwidth.

[0138] In one embodiment, the adjustment module 114 can also be used to determine the size relationship between the starting position of the NR spectrum bandwidth and the starting position of the LTE spectrum bandwidth; if the starting position of the LTE spectrum bandwidth is smaller than the starting position of the NR spectrum bandwidth, the starting position of the LTE spectrum bandwidth is replaced by the starting position of the NR spectrum bandwidth, so that the starting position of the adjusted LTE spectrum bandwidth is included in the NR spectrum bandwidth; determine the size relationship between the ending position of the NR spectrum bandwidth and the ending position of the LTE spectrum bandwidth; if the ending position of the LTE spectrum bandwidth is larger than the ending position of the NR spectrum bandwidth, the ending position of the LTE spectrum bandwidth is replaced by the ending position of the NR spectrum bandwidth, so that the ending position of the adjusted LTE spectrum bandwidth is included in the NR spectrum bandwidth.

[0139] In one embodiment, after performing CRS rate matching according to the adjusted starting position and ending position of the LTE spectrum bandwidth, the adjustment module 114 can also be used to determine whether the starting position and ending position of the NR spectrum bandwidth have changed; if changed, the starting position and ending position of the LTE spectrum bandwidth are adjusted by the starting position and ending position of the NR spectrum bandwidth so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth.

[0140] In one embodiment, the adjustment module 114 can also be used to re-acquire the starting position and the ending position of the NR spectrum bandwidth; obtain a comparison result by comparing the re-acquired starting position and the ending position of the NR spectrum bandwidth with the starting position and the ending position of the NR spectrum bandwidth acquired last time; and determine whether the starting position and the ending position of the NR spectrum bandwidth have changed based on the comparison result.

[0141] In the embodiment of the present disclosure, the CRS rate matching device adjusts the starting position and the ending position of the LTE spectrum bandwidth by the starting position and the ending position of the NR spectrum bandwidth, so that the LTE spectrum bandwidth is included in the NR spectrum bandwidth, thereby ensuring correct CRS rate matching.

[0142] Furthermore, when the starting position and the ending position of the NR spectrum bandwidth change, the present invention can readjust the starting position and the ending position of the LTE spectrum bandwidth, thereby ensuring that the LTE spectrum bandwidth is contained in the NR spectrum bandwidth, further ensuring the correct CRS rate matching.
