[0002] In the existing Release 15 NR technology, the position of the initial active downlink bandwidth part (BWP) is usually equal to the position of the control resource set (CORESET) of the Type0-PDCCH. Therefore, the user equipment (also known as terminal) can directly obtain the position of the initial active downlink BWP according to the position of the CORESET of the Type0-PDCCH indicated by the management information base (MIB) or the radio resource control layer (RRC). The Type0-PDCCH is also known as the remaining minimum system information (RMSI) PDCCH.

[0003] However, in the NR unlicensed spectrum, the bandwidth of the initial active downlink BWP is close to 20MHz and can be fixed within the WiFi channel in the 5GHz spectrum. The CORESET of the Type0-PDCCH can have a certain degree of freedom, such as a bandwidth less than 20MHz. Therefore, the position of the initial active downlink BWP can not be equal to the position of the CORESET of the Type0-PDCCH.

[0051] In the prior art, the position of the initially activated downlink BWP is usually equal to the position of the CORESET of the first type PDCCH (Type0-PDCCH search space set), however, in the NR unlicensed spectrum, the position of the initially activated downlink BWP can not be equal to the position of the CORESET of the first type PDCCH, resulting in that the user equipment is difficult to determine the resource configuration of the initially activated downlink BWP and the resource configuration information of the first type PDCCH.

[0052] In this paper, the PRB (Physical Resource Block) with the minimum index can also be referred to as the first PRB, that is, the PRB with the minimum index of the synchronization signal block can be referred to as the first PRB of the synchronization signal block, the PRB with the minimum index of the initially activated downlink BWP can be referred to as the first PRB of the initially activated downlink BWP, and the PRB with the minimum index of the CORESET of the first type PDCCH can be referred to as the first PRB of the CORESET of the first type PDCCH.

[0053] In this paper, the PRB quantity of the initially activated downlink BWP can also be referred to as the continuous PRB quantity of the initially activated downlink BWP.

[0054] In this document, the PRB of the minimum index of the synchronization signal block can be the PRB of the minimum index on the common RB (common Resource Block) overlapping with the corresponding synchronization signal block.

[0055] The PRB in this document can also be referred to as a RB (Resource Block).

[0056] In this document, the bitmap resource unit can also be referred to as a PRB group. Generally, a bit of 1 in the bitmap indicates that a PRB in the bitmap resource unit is a PRB of the CORESET, and a bit of 0 in the bitmap indicates that a PRB in the bitmap resource unit is not a PRB of the CORESET. In this document, the pre-divided channel can be a pre-divided frequency range, and the pre-divided channel can also be a pre-divided frequency range for unlicensed spectrum, such as a 20MHz channel defined by WiFi technology.

[0057] In the embodiment of the application, the position of the initial active downlink BWP is determined according to the frequency domain position of the PRB of the minimum index of the synchronization signal block, and the position of the CORESET of the first type of PDCCH is determined. The scheme of the embodiment of the application can enable the user equipment to obtain the resource configuration of the initial active downlink BWP and the resource configuration information of the first type of PDCCH in the NR unlicensed spectrum.

[0058] In order to make the above-mentioned purposes, features and benefits of the application more obvious and easy to understand, the specific embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0059] Reference Figure 1 , Figure 1 is a flowchart of the first resource information determination method in the embodiment of the application. The first resource information determination method can include steps S11 to S13:

[0060] Step S11: determining the frequency domain position of the PRB of the minimum index of the synchronization signal block;

[0061] Step S12: determining the position of the initial active downlink BWP according to the frequency domain position of the PRB of the minimum index of the synchronization signal block, wherein the position of the initial active downlink BWP includes the frequency domain position of the PRB of the minimum index of the initial active downlink BWP and the number of PRBs of the initial active downlink BWP;

[0062] Step S13: determining the location of the CORESET of the first type of PDCCH, wherein the location of the CORESET includes the frequency domain location of the PRB with the minimum index of the CORESET and the number of PRBs of the CORESET, or the bitmap-based PRB location of the CORESET.

[0063] In the embodiment of the application, the location of the CORESET is determined by using the frequency domain location of the PRB with the minimum index of the CORESET and the number of PRBs of the CORESET, and the location of the CORESET is a continuous PRB, and the number of PRBs of the CORESET is a continuous number of PRBs.

[0064] In the embodiment of the application, the location of the CORESET is determined by using the bitmap-based PRB location of the CORESET, and the location of the CORESET can be a non-continuous PRB. This method is more flexible.

[0065] In the specific implementation of step S11, the frequency domain location of the physical resource block (PRB) with the minimum index of the synchronization signal block is determined.

[0066] In the 5G system, the synchronization signal and the broadcast channel are transmitted in the form of a synchronization signal block, and the function of beam sweeping is introduced. The primary synchronization signal (PSS), the secondary synchronization signal (SSS) and the physical broadcast channel (PBCH) are in the synchronization signal block (SS / PBCH block). Each synchronization signal block can be regarded as the resource of one beam (analog domain) in the beam sweeping process. A plurality of synchronization signal blocks constitute a synchronization signal burst (SS-burst). The synchronization signal burst can be regarded as a relatively concentrated block of resources containing a plurality of beams. A plurality of synchronization signal bursts constitute a synchronization signal burst set (SS-burst-set). The synchronization signal block is repeatedly transmitted on different beams, which is a beam sweeping process. Through the training of beam sweeping, the user equipment can perceive that the signal received on which beam is the strongest.

[0067] In the embodiment of the application, the location of the CORESET is determined by using the frequency domain location of the PRB with the minimum index of the CORESET and the number of PRBs of the CORESET, and the location of the CORESET is a continuous PRB, and the number of PRBs of the CORESET is a continuous number of PRBs.

[0068] In the implementation of step S12, the position of the initial active downlink BWP can be determined according to the frequency domain position of the PRB with the minimum index of the synchronization signal block.

[0069] Specifically, the position of the initial active downlink BWP can be determined in various ways, for example, the frequency domain position of the initial active downlink BWP is determined according to the offset provided by the base station, the number of PRBs of the initial active downlink BWP is obtained from the base station, and specific determination methods will be described in subsequent specific embodiments.

[0070] In the implementation of step S13, the PRB position of the CORESET of the first type of PDCCH based on the bitmap can be determined.

[0071] Specifically, the position of the CORESET of the first type of PDCCH can be determined in various ways, for example, obtained from the base station, or the frequency domain position of the CORESET of the first type of PDCCH is determined according to the offset provided by the base station, the number of PRBs of the CORESET of the first type of PDCCH is obtained from the base station, and the PRB position of the CORESET of the first type of PDCCH based on the bitmap can also be determined, and specific determination methods will be described in subsequent specific embodiments.

[0072] The first type of PDCCH can be an RMSI PDCCH, and in the NR unlicensed spectrum, the monitoring occasion of the RMSI PDCCH is related to the CORESET duration of the RMSI PDCCH, so that the time domain resources of the synchronization signal block and the RMSI PDCCH are ensured to be within a burst.

[0073] As a non-limiting specific application, the CORESET can be obtained and the RMSI PDCCH can be determined according to the frequency domain position of the PRB with the minimum index of the CORESET, and a PDSCH scheduled by the RMSI PDCCH on the initial active downlink BWP can be received according to the RMSI PDCCH and the frequency domain position of the PRB with the minimum index of the initial active downlink BWP.

[0074] In the embodiments of the present application, the position of the initial active downlink BWP is determined according to the frequency domain position of the PRB with the minimum index of the synchronization signal block, and the position of the CORESET of the first type of PDCCH is determined. By using the scheme of the embodiments of the present application, the user equipment can obtain the resource configuration of the initial active downlink BWP and the resource configuration information of the first type of PDCCH in the NR unlicensed spectrum.

[0075] Reference Figure 2 , Figure 2is a flow chart of a second resource information determination method in an embodiment of the present application. The second resource information determination method can include steps S21 to S25, which are described below.

[0076] In step S21, a first offset between a frequency domain position of a minimum indexed PRB of the synchronization signal block and a minimum indexed PRB of the initial active downlink BWP is obtained from the base station.

[0077] It should be noted that the frequency domain position of the minimum indexed PRB of the synchronization signal block can be obtained by detection, and specific details can be referred to Figure 1 The related description of step S11 is shown, and will not be repeated here.

[0078] In step S22, the frequency domain position of the minimum indexed PRB of the initial active downlink BWP is determined according to the first offset and the frequency domain position of the minimum indexed PRB of the synchronization signal block.

[0079] In step S23, the number of PRBs of the initial active downlink BWP is obtained from the base station.

[0080] In a specific embodiment of the present application, the number of PRBs of the initial active downlink BWP obtained from the base station can be obtained.

[0081] In another specific embodiment of the present application, the number of resource units of the initial active downlink BWP obtained from the base station can be obtained, and then the user equipment determines the number of PRBs according to the number of resource units.

[0082] In step S24, a bitmap of a bitmap resource unit of the CORESET of the first type PDCCH is obtained from the base station, wherein each resource unit includes one or more PRBs, and the bitmap resource unit and the bit in the bitmap are one-to-one corresponding.

[0083] In a specific implementation, the starting position of the bitmap resource unit can be determined by the base station indication, or can be the frequency domain position of the minimum indexed PRB of the initial active downlink BWP.

[0084] In a specific implementation, the frequency domain resource of the CORESET of the first type PDCCH is not continuous, so it has higher freedom.

[0085] It should be noted that the bit can correspond to the concept of bit in bitmap, and if the minimum unit in the bitmap is represented by other units instead of bits, each resource unit can correspond to other minimum units in the bitmap.

[0086] In one non-limiting example, each resource unit can include 6 PRBs.

[0087] In step S25, a bitmap-based PRB location of the CORESET of the first type of PDCCH is determined according to the bitmap.

[0088] It can be understood that the user equipment can determine the location of the CORESET through the bitmap and the bitmap-based PRB location of the CORESET of the first type of PDCCH.

[0089] In the embodiment of the present application, the frequency domain location of the PRB of the minimum index of the initial active downlink BWP is determined through the first offset, and then the number of PRBs of the initial active downlink BWP is obtained from the base station, so as to determine the location of the initial active downlink BWP; and then the location of the CORESET of the first type of PDCCH is determined through the bitmap of the bitmap resource unit of the CORESET of the first type of PDCCH.

[0090] Reference is made to Figure 3 , Figure 3 is a flowchart of a third resource information determination method in the embodiment of the present application. The third resource information determination method can include steps S31 to S35, which will be described below.

[0091] In step S31, a first offset between the frequency domain location of the PRB of the minimum index of the synchronization signal block and the frequency domain location of the PRB of the minimum index of the initial active downlink BWP is obtained from the base station.

[0092] In step S32, the frequency domain location of the PRB of the minimum index of the initial active downlink BWP is determined according to the first offset and the frequency domain location of the PRB of the minimum index of the synchronization signal block.

[0093] It should be noted that the frequency domain location of the PRB of the minimum index of the synchronization signal block can be obtained by detection, and more details of steps S31 to S32 can be performed by referring to the description of steps S21 and S22 in Figure 2 .

[0094] In step S33, the number of PRBs of the initial active downlink BWP is obtained from the base station.

[0095] In one specific implementation of the embodiment of the present application, the number of PRBs of the initial active downlink BWP obtained from the base station can be obtained.

[0096] In another specific implementation of the embodiments of the present application, the number of resource units of the initial active downlink BWP can be acquired from the base station, and then the user equipment determines the number of PRBs according to the number of resource units.

[0097] In step S34, the frequency domain position of the PRB with the minimum index of the CORESET of the first type of PDCCH is determined according to the second offset between the PRB with the minimum index of the initial active downlink BWP and the PRB with the minimum index of the CORESET of the first type of PDCCH, and the frequency domain position of the PRB with the minimum index of the initial active downlink BWP.

[0098] The second offset can be predefined, for example, specified by a communication protocol, or the second offset can also be acquired from the base station. Generally, if the second offset is predefined, the signaling overhead is smaller, and if the second offset is acquired from the base station, the signaling overhead is larger but the flexibility is higher.

[0099] When the second offset is predefined, the second offset can be predefined as 0. In this way, the system implementation can be simplified.

[0100] In step S35, the number of PRBs of the CORESET is acquired from the base station.

[0101] In one specific implementation of the embodiments of the present application, the number of PRBs of the CORESET of the first type of PDCCH can be acquired from the base station.

[0102] In another specific implementation of the embodiments of the present application, the number of resource units of the CORESET of the first type of PDCCH can be acquired from the base station, and then the user equipment determines the number of PRBs according to the number of resource units, wherein the resource units of the CORESET are different from the bitmap resource units of the CORESET.

In specific implementations, under the mapping relationship, once the frequency band in which the initial active downlink BWP is located and the subcarrier spacing of the initial active downlink BWP are determined, the frequency domain position of the minimum indexed PRB of the initial active downlink BWP can be determined.

[0125] In a specific implementation, by setting the frequency domain position of the PRB with the minimum index of the CORESET of the first type PDCCH to be the same as the frequency domain position of the PRB with the minimum index of the initial active downlink BWP, the case where the frequency domain positions of the two are the same in the prior art can be followed, thereby reducing the amount of calculation and saving resources.

[0126] In step S55, the PRB quantity of the CORESET is acquired from the base station.

[0129] In the embodiment of the present application, the frequency domain position of the PRB with the minimum index of the initial active downlink BWP is determined through the first offset, and then the number of PRBs of the initial active downlink BWP is determined through the second mapping relationship, so as to determine the position of the initial active downlink BWP. Then, the frequency domain position of the PRB with the minimum index of the CORESET of the first type of PDCCH is determined to be the same as the frequency domain position of the PRB with the minimum index of the initial active downlink BWP, and then the number of PRBs of the CORESET is obtained from the base station, so as to determine the position of the CORESET of the first type of PDCCH.

[0130] With reference to Figure 6 , Figure 6 is a flowchart of a sixth resource information determination method in the embodiment of the present application. The sixth resource information determination method can include steps S61 to S65, which will be described below.

[0131] In step S61, the pre-divided channel in which the synchronization signal block is located is determined according to the frequency domain position of the PRB with the minimum index of the synchronization signal block.

[0132] In specific embodiments, the determination of the pre-divided channel in which the synchronization signal block is located can be the determination of which pre-divided channel the synchronization signal block is contained in, or the determination of which pre-divided channel the synchronization signal block overlaps.

[0133] In specific embodiments, the pre-divided channel can be a pre-divided frequency range. The pre-divided channel can be a pre-divided frequency range for unlicensed spectrum, such as a 20MHz channel defined by WiFi technology.

[0134] In specific embodiments, for the frequency domain position of the initial active downlink BWP, the user equipment can derive the pre-divided channel in which the synchronization signal block is located after obtaining the frequency domain position of the synchronization signal block. It should be noted that the frequency domain position of the PRB with the minimum index of the synchronization signal block can be obtained by detection.

[0135] In step S62, the pre-divided channel in which the synchronization signal block is located has a preset third mapping relationship with the frequency domain position of the PRB with the minimum index of the initial active downlink BWP, and the frequency domain position of the PRB with the minimum index of the initial active downlink BWP is determined according to the channel and the third mapping relationship.

[0136] In a specific implementation, the pre-defined channel and all PRB positions of the initial active downlink BWP can be pre-defined or pre-defined in a table, and the user equipment can obtain the specific relationship between the pre-defined channel and all PRB positions of the initial active downlink BWP through the row or column of the table indicated by the base station.

[0137] More specifically, the pre-defined channel where the synchronization signal block is located and the frequency domain position of the PRB with the smallest index of the initial active downlink BWP can have a pre-defined mapping relationship table, or the mapping relationship between the two can also be provided in a textual description manner. In the embodiment of the present application, the third mapping relationship between the pre-defined channel where the synchronization signal block is located and the frequency domain position of the PRB with the smallest index of the initial active downlink BWP can be determined according to the pre-defined mapping relationship table or the text.

[0138] In step S63, the pre-defined channel where the synchronization signal block is located and the number of PRBs of the initial active downlink BWP have a pre-set fourth mapping relationship, and the number of PRBs of the initial active downlink BWP is determined according to the channel and the fourth mapping relationship.

In the embodiment of the present application, the fourth mapping relationship between the pre-defined channel where the synchronization signal block is located and the number of PRBs of the initial active downlink BWP can be determined according to the pre-defined mapping relationship table or the text.

[0140] In step S64, a bitmap resource unit bitmap of the CORESET of the first type PDCCH is obtained from the base station, wherein each resource unit includes one or more PRB bitmap resource units and bits in the bitmap are one-to-one corresponding.

[0141] In a specific implementation, the starting position of the bitmap resource unit can be determined by the base station indication, or can be the frequency domain position of the PRB with the smallest index of the initial active downlink BWP.

[0142] In a specific implementation, the frequency domain resource of the CORESET of the first type PDCCH is not continuous, so it has higher freedom.

[0143] It should be noted that the bit can correspond to the concept of bit in the bitmap, and if the smallest unit in the bitmap is represented by other units instead of bits, each resource unit can correspond to other smallest units in the bitmap.

[0144] In one non-limiting example, each resource unit can include 6 PRBs.

[0145] In step S65, a bitmap-based PRB location of the CORESET of the first-type PDCCH is determined according to the bitmap.

[0146] It can be understood that the user equipment can determine the location of the CORESET through the bitmap and the bitmap-based PRB location of the CORESET of the first-type PDCCH.

[0147] In the embodiment of the present application, the frequency domain location of the PRB with the minimum index of the initial active downlink BWP is determined through the third mapping relationship, and then the number of initial active downlink BWPs is determined through the fourth mapping relationship; then the location of the CORESET of the first-type PDCCH is determined through the bitmap of the bitmap resource unit of the CORESET of the first-type PDCCH.

[0161] Refer to Figure 8 , Figure 8is a flowchart of the eighth method for determining resource information in the embodiments of the present application. The eighth method for determining resource information can include steps S81 to S85, which are described below.

[0162] In step S81, a pre-divided channel in which the synchronization signal block is located is determined according to the frequency domain position of the PRB with the minimum index of the synchronization signal block.

[0163] In specific embodiments, the determination of the pre-divided channel in which the synchronization signal block is located can be a determination of which pre-divided channel the synchronization signal block is contained in, or a determination of which pre-divided channel the synchronization signal block overlaps. In specific embodiments, the pre-divided channel can be a pre-divided frequency range. The pre-divided channel can be a pre-divided frequency range for unlicensed spectrum, such as a 20MHz channel defined by WiFi technology.

[0164] In step S82, the pre-divided channel in which the synchronization signal block is located has a preset third mapping relationship with the frequency domain position of the PRB with the minimum index of the initial active downlink BWP, and the frequency domain position of the PRB with the minimum index of the initial active downlink BWP is determined according to the channel and the third mapping relationship.

[0169] In step S85, the number of PRBs of the CORESET is obtained from the base station.

[0170] ​In an embodiment of the present application, the PRB number of the CORESET of the first type of PDCCH acquired from the base station can be acquired.

[0171] In another embodiment of the present application, the number of resource units of the CORESET of the first type of PDCCH acquired from the base station can be acquired, and then the user equipment determines the PRB number according to the number of resource units, wherein the resource units of the CORESET are different from the bitmap resource units of the CORESET.

[0172] In an embodiment of the present application, the frequency domain position of the PRB with the minimum index of the initial active downlink BWP can be determined through a third mapping relationship, and then the number of initial active downlink BWPs is determined through a fourth mapping relationship; then the frequency domain position of the PRB with the minimum index of the CORESET of the first type of PDCCH is determined through a third offset, and then the PRB number of the CORESET is acquired from the base station, so as to determine the position of the CORESET of the first type of PDCCH.

[0173] Reference Figure 9 , Figure 9 is a flowchart of the ninth resource information determination method in an embodiment of the present application. The ninth resource information determination method can include steps S91 to S95, and each step will be described below.

[0174] In step S91, a first offset between the frequency domain position of the PRB with the minimum index of the initial active downlink BWP and the frequency domain position of the PRB with the minimum index of the synchronization signal block is acquired from the base station.

[0175] In step S92, the frequency domain position of the PRB with the minimum index of the initial active downlink BWP is determined according to the first offset and the frequency domain position of the PRB with the minimum index of the synchronization signal block.

[0176] It should be noted that the frequency domain position of the PRB with the minimum index of the synchronization signal block can be acquired by detection, and more detailed contents of steps S91 to S92 can be performed by referring to the description of steps S21 and S22 in Figure 2 .

[0177] In step S93, the frequency domain position of the PRB with the minimum index of the CORESET of the first type of PDCCH is determined to be the same as the frequency domain position of the PRB with the minimum index of the initial active downlink BWP.

[0178] In a specific implementation, by setting the frequency domain position of the PRB of the minimum index of the CORESET of the first type of PDCCH to be the same as the frequency domain position of the PRB of the minimum index of the initial active downlink BWP, the case where the frequency domain positions of the two are the same in the prior art can be followed, thereby reducing signaling overhead and saving resources.

[0179] In step S94, the PRB number of the CORESET of the first type of PDCCH, the duration of the CORESET of the first type of PDCCH, and the subcarrier spacing of the initial active downlink BWP have a preset fifth mapping relationship, and the PRB number of the CORESET of the first type of PDCCH is determined according to the duration, the subcarrier spacing, and the fifth mapping relationship.

[0180] In a specific implementation, the PRB number of the CORESET of the first type of PDCCH, the duration of the CORESET of the first type of PDCCH, and the subcarrier spacing of the initial active downlink BWP can have a predefined mapping relationship table, or the mapping relationship between the three can also be provided in a textual description manner. In the embodiments of the present application, the fifth mapping relationship between the PRB number of the CORESET of the first type of PDCCH, the duration of the CORESET of the first type of PDCCH, and the subcarrier spacing of the initial active downlink BWP can be determined according to the predefined mapping relationship table or the text.

[0181] More specifically, the frequency domain position of the initial active downlink BWP is still equal to the frequency domain position of the CORESET of the RMSI PDCCH. However, in order to reduce the blind detection complexity of the user equipment, the frequency domain resource of the CORESET of the RMSI PDCCH needs to be limited.

[0182] In a specific implementation, under a 30kHz subcarrier spacing, there are about 51 PRBs under a 20MHz bandwidth, so when the duration of the CORESET of the RMSI PDCCH is 1 OFDM symbol, the PBR number of the CORESET of the RMSI PDCCH can be 48, and when the duration of the CORESET of the RMSI PDCCH is 2 OFDM symbols, the PBR number of the CORESET of the RMSI PDCCH can be 24.

[0183] In another specific embodiment, there are approximately 24 PRBs in a 20MHz bandwidth under a 60kHz subcarrier spacing, so when the duration of the CORESET of the RMSI PDCCH is 1 OFDM symbol, the number of PRBs of the CORESET of the RMSI PDCCH can be 24, and when the duration of the CORESET of the RMSI PDCCH is 2 OFDM symbols, the number of PRBs of the CORESET of the RMSI PDCCH can be 12 or 24.

[0184] The duration can be predefined or acquired from the base station.

[0185] In step S95, it is determined that the number of PRBs of the CORESET of the first type of PDCCH is equal to the number of PRBs of the initially activated downlink BWP.

[0186] In a specific implementation, by setting the number of PRBs of the CORESET of the first type of PDCCH to be equal to the number of PRBs of the initially activated downlink BWP, the case where the number of PRBs of the two is the same in the prior art can be followed, thereby reducing signaling overhead and saving resources.

[0187] In the embodiment of the application, by the first offset, the frequency domain position of the PRB with the minimum index of the initially activated downlink BWP is determined, and then by the fifth mapping relationship, the number of PRBs of the CORESET is determined, and then it is determined that the frequency domain position of the PRB with the minimum index of the CORESET of the first type of PDCCH is the same as the frequency domain position of the PRB with the minimum index of the initially activated downlink BWP, and the number of PRBs of the CORESET of the first type of PDCCH is equal to the number of PRBs of the initially activated downlink BWP, thereby determining the position of the initially activated downlink BWP and the CORESET of the first type of PDCCH.

[0188] Further, the determination of the position of the CORESET of the first type of PDCCH can further include determining the time domain position of the CORESET of the first type of PDCCH.

[0189] Specifically, the step of determining the time domain position of the CORESET of the first type of PDCCH can include: according to the duration of the CORESET of the first type of PDCCH being 2 OFDM symbols, determining that the starting symbol of the monitoring occasion of the first type of PDCCH is symbol 0 and / or symbol 7 within a time slot; and according to the duration of the CORESET of the first type of PDCCH being 1 OFDM symbol, determining that the starting symbol of the monitoring occasion of the first type of PDCCH is symbol 0 and / or symbol 1 within a time slot.

[0190] In the embodiment of the present application, by determining the time domain position of the CORESET of the first type PDCCH, the frequency domain position of the PRB of the minimum index of the CORESET, and the PRB quantity of the CORESET, the resource information of the CORESET of the first type PDCCH can be determined more completely.

[0191] In the embodiment of the present application, the position of the initial active downlink BWP can be determined in various ways, which helps the user equipment to select according to the specific situation and improves the user experience.

[0192] In the embodiment of the present application, the position of the CORESET of the first type PDCCH can be determined in various ways, which helps the user equipment to select according to the specific situation and improves the user experience.

[0211] The embodiment of the present application further provides a storage medium, which has computer instructions stored thereon, and the computer instructions perform the steps of the resource information determination method shown in the embodiment of the present application when running. Figures 1 to 9 The storage medium can be a computer readable storage medium, for example, can include a non-volatile memory or a non-transitory memory, and can further include an optical disc, a mechanical hard disk, a solid state disk, etc.

[0212] The embodiment of the present application further provides a user equipment, which includes a memory and a processor, and the memory has computer instructions capable of running on the processor stored thereon, and the processor performs the steps of the resource information determination method shown in the embodiment of the present application when running the computer instructions. Figures 1 to 9 The user equipment includes but is not limited to a mobile phone, a computer, a tablet computer, etc.

[0213] It is appreciated that in LTE Release 12, Discovery Reference Signal (DRS) is defined for user equipment to synchronize (time and frequency tracking) and measure SCell (Secondary Cell), which can be referred to as the "discovery" function of SCell. The advantage of using DRS is that DRS is a long period signal, which causes less interference to the whole network. DRS is composed of PSS / SSS / CRS, in which CRS is a cell-specific reference signal. For FDD system, the DRS duration is 1 to 5 consecutive subframes; for TDD system, the DRS duration is 2 to 5 consecutive subframes. The transmission occasion of DRS is defined by Discovery Measurement Timing Configuration (DMTC), in which user equipment assumes that DRS occurs once in each DMTC period.

[0214] In LTE Licensed Assisted Access (LAA), DRS can be used for the discovery function of SCell on unlicensed spectrum, due to its long period characteristic, which reduces the interference to LAA system and other systems (such as Wifi system) sharing the unlicensed spectrum. The duration of LAA DRS is 12 OFDM symbols within a non-empty subframe, in order to further reduce the interference to LAA system and other systems. LAA DRS also includes PSS / SSS / CRS.

[0215] There are two cases for the occurrence occasion of LAA DRS:

[0216] Case 1: User equipment can assume that LAA DRS can occur in any subframe in DMTC, and user equipment can assume that LAA DRS occurs in the first subframe in DMTC containing one PSS, one SSS and CRS. That is, user equipment assumes that: before transmitting in DMTC, base station performs Listen Before Talk (LBT), if the channel is detected to be idle, then the base station transmits a DRS in a non-empty subframe.

[0217] Case 2: When LAA DRS is transmitted together with PDSCH / PDCCH / EPDCCH, LAA DRS can only occur in subframe 0 and subframe 5. That is, if DMTC contains subframe 0 or 5, and user equipment needs to detect PDCCH / EPDCCH or receive PDSCH on subframe 0 or 5, then user equipment assumes that DRS only occurs on subframe 0 or 5.

[0218] Further, the remaining minimum system information in 5G is equivalent to SIB1 in LTE, which includes the main system information except MIB. The RMSI is carried in PDSCH, while the PDSCH is scheduled by PDCCH. The PDSCH carrying RMSI is generally referred to as RMSI PDSCH, and the PDCCH scheduling RMSI PDSCH is generally referred to as RMSI PDCCH.

[0219] Generally, a search space set contains properties such as monitoring occasions of PDCCH, search space type, etc. A search space set is generally bound to a CORESET, and the CORESET contains properties such as frequency domain resources and duration of PDCCH, etc.

[0220] The search space set (search space) where the RMSI PDCCH is located is generally referred to as Type0-PDCCH search space set. Generally, the Type0-PDCCH search space set configured by MIB or RRC in the case of handover, etc. is referred to as search space 0 (or search space set 0), and the bound CORESET is referred to as CORESET 0. In addition to the search space set of RMSI PDCCH, other common search spaces or common search space sets, such as the search space set of OSI PDCCH (Type0A-PDCCH search space set), the search space set of RAR PDCCH (Type1-PDCCH search space set), the search space set of paging PDCCH (Type2-PDCCH search space set), etc. can be the same as search space set 0 by default. Generally, the above-mentioned common search spaces or common search space sets can be reconfigured.

[0221] Further, on the unlicensed spectrum of NR, it is necessary to define a synchronization signal block so that the user equipment can detect the NR unlicensed spectrum cell in cell search. The synchronization signal block can be contained in the DRS as a whole containing the synchronization signal block; or no DRS is defined, and the synchronization signal block exists independently.

[0222] On the NR unlicensed spectrum, the base station needs to perform LBT before transmitting the DRS or synchronization signal block. Only when the signal is idle, the base station transmits the DRS or synchronization signal block. Otherwise, the base station performs LBT again after a certain period of time. The transmission of the DRS or synchronization signal block is performed within a certain transmission window. The transmission window can be agreed by the base station and the user equipment, or configured by the RRC signaling through the DMTC or the SMTC (Synchronization Measurement Timing Configuration).

[0223] Although the present application has been disclosed with reference to the above embodiments, it is not intended to limit the present application to the above embodiments. Any person skilled in the art, without departing from the spirit and scope of the present application, can make various modifications and changes, and the scope of protection of the present application should be limited by the scope defined in the claims.
