Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an information transmission method and device / storage medium / apparatus. Background Technology

[0002] In 3GPPR18 (Release 18), transmission costs are reduced by introducing Redcap UE (Reduced Capability User Equipment).

[0003] In related technologies, the maximum bandwidth of a Redcap UE is 5MHz (Hertz). However, the SCS (Sub-Carrier Space) of the SSB (Synchronization Signal and PBCH block) includes 15kHz, 30kHz, and other frequency values, which can be found in relevant 3GPP standards. Specifically, for a Redcap UE, when the SSB subcarrier space is 30kHz, the total bandwidth occupied by the SSB is 7.2MHz, exceeding the bandwidth range of the Redcap UE. This will cause the Redcap UE to fail to decode the MIB (Master information block) message, resulting in the failure of SSB transmissions with a subcarrier space of 30kHz or higher.

[0067] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0068] The information transmission method, apparatus, user equipment, base station and storage medium provided in this disclosure are described in detail below with reference to the accompanying drawings.

[0069] Figure 1 This is a flowchart illustrating an information transmission method provided in an embodiment of this disclosure, applied to RedcapUE, such as... Figure 1 As shown, the information transmission method may include the following steps:

[0070] Step 101: Determine the parameters of the SSB resources used for transmitting Redcap UE.

[0071] It should be noted that, in one embodiment of this disclosure, the UE can be a device that provides voice and / or data connectivity to a user. The terminal device can communicate with one or more core networks via a RAN (Radio Access Network). The UE can be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE can also be a device from an unmanned aerial vehicle. Alternatively, the UE can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. Alternatively, the UE can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0072] In one embodiment of this disclosure, the aforementioned Redcap UE may specifically be a Redcap UE applied in Release 18. The maximum bandwidth range supported by this Redcap UE is 5MHz. Furthermore, in one embodiment of this disclosure, based on protocol specifications, cells supporting Redcap UE access can consistently transmit an SSB with SCS=15kHz to perform one or more functions such as downlink synchronization, initial cell search, RRM (Radio Resource Management) measurement, radio link monitoring (RLM) measurement, and beam management. Cells not supporting Redcap UE access can use an SSB with SCS=30kHz to perform one or more functions such as downlink synchronization, initial cell search, RRM measurement, RLM measurement, and beam management.

[0073] Furthermore, in one embodiment of this disclosure, the bandwidth of the SSB resources used for transmitting Redcap UE can be less than or equal to the bandwidth range of Redcap UE, thereby ensuring that the transmitted SSB resources can always be successfully received and decoded by Redcap UE.

[0074] Furthermore, in one embodiment of this disclosure, the parameters for transmitting the SSB resources of the Redcap UE may include: parameters corresponding to the SSB of the Redcap UE; or, parameters of the PBCH dedicated to transmitting the SSB of the Redcap UE.

[0075] In one embodiment of this disclosure, the parameters of the SSB corresponding to the Redcap UE may include:

[0076] Resources corresponding to the first subcarrier interval of the SSB for transmitting Redcap UE, wherein the bandwidth of the resources used for transmitting SSB is less than or equal to the bandwidth range of Redcap UE;

[0077] or

[0078] Resources dedicated to transmitting SSBs corresponding to the Redcap UE, wherein the bandwidth of resources dedicated to transmitting SSBs corresponding to the Redcap UE is less than or equal to the bandwidth range of the Redcap UE.

[0079] In one embodiment of this disclosure, the SSB corresponding to the Redcap UE can be an SSB independently configured by the base station for the Redcap UE. Furthermore, the structure of the SSB corresponding to the Redcap UE can differ from the structure of the SSB corresponding to a regular UE, where the regular UE can be a non-Redcap UE and / or a Redcap UE in Release 17. The structure of the SSB corresponding to the Redcap UE will be described in detail in subsequent embodiments.

[0080] Furthermore, in one embodiment of this disclosure, the resources dedicated to transmitting the SSB corresponding to the Redcap UE may correspond to the first subcarrier interval. In another embodiment of this disclosure, the resources dedicated to transmitting the SSB corresponding to the Redcap UE may correspond to the first subcarrier interval and / or the second subcarrier interval.

[0081] In one embodiment of this disclosure, the first subcarrier interval can be a subcarrier interval in which the RdeCapUE can receive the complete SSB, or a subcarrier interval in which the RedCapUE can receive the PBCH in the SSB; for example, the first subcarrier interval can be 15kHz. The second subcarrier interval can be any subcarrier interval other than the first subcarrier interval. For example, the second subcarrier interval can be 30kHz~240kHz; at these subcarrier intervals, the RdeCapUE cannot receive the complete SSB, or the RdeCapUE cannot receive the PBCH in the SSB.

[0082] In all embodiments disclosed herein, the specific values ​​of the first subcarrier interval and the second subcarrier interval are not specifically limited; those skilled in the art will understand that the first subcarrier interval is the subcarrier interval in which the RdeCapUE can receive the complete SSB in the related technology, or the subcarrier interval in which the RedCapUE can receive the PBCH of the SSB in the related technology; the second subcarrier interval can be any subcarrier interval other than the first subcarrier interval.

[0083] Furthermore, the parameters of the PBCH of the SSB dedicated to transmitting Redcap UEs mentioned above may include:

[0084] The time-frequency domain resources corresponding to the Redcap UE for transmitting PBCH are at least two parts, wherein the frequency domain resource length of each part of the time-frequency domain resources is less than or equal to the bandwidth range of the Redcap UE, and the frequency domain resource length of each part of the time-frequency domain resources is less than the frequency domain resource length of the time-frequency domain resources corresponding to the ordinary UE for transmitting PBCH.

[0085] or

[0086] Time-frequency domain resources dedicated to transmitting time-frequency domain resources corresponding to the PBCH of the Redcap UE, wherein the length of the frequency domain resources dedicated to transmitting time-frequency domain resources corresponding to the PBCH of the Redcap UE is less than or equal to the bandwidth range of the Redcap UE.

[0087] Step 102: Receive the SSB resources sent by the base station based on the parameters of the determined SSB resources.

[0088] In one embodiment of this disclosure, the method by which the Redcap UE receives the SSB resources sent by the base station will differ depending on the parameters of the SSB resources determined in step 102. This will be described in detail in subsequent embodiments.

[0089] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCH transmitted by the base station on the new time-frequency domain resource. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0090] Figure 2 This is a flowchart illustrating an information transmission method provided in another embodiment of the present disclosure, applied to a Redcap UE, such as... Figure 2 As shown, the information transmission method may include the following steps:

[0091] Step 201: Determine the parameters of the SSB resources used for transmitting the Redcap UE. The parameters of the SSB resources used for transmitting the Redcap UE include resources corresponding to the first subcarrier interval of the SSB for transmitting the Redcap UE, wherein the bandwidth of the resources used for transmitting the SSB is less than or equal to the bandwidth range of the Redcap UE.

[0092] In one embodiment of this disclosure, the first subcarrier spacing may be, for example, 15 kHz.

[0093] Step 202: Receive SSB resources transmitted by the base station at the first subcarrier interval.

[0094] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCH transmitted by the base station on the new time-frequency domain resource. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0095] Figure 3a This is a flowchart illustrating an information transmission method provided in another embodiment of the present disclosure, applied to a Redcap UE, such as... Figure 3a As shown, the information transmission method may include the following steps:

[0096] Step 301a: Determine the parameters for the SSB resources used to transmit the Redcap UE, including resources dedicated to transmitting the SSB corresponding to the Redcap UE.

[0097] In one embodiment of this disclosure, the resources dedicated to transmitting SSBs corresponding to a Redcap UE can be a first subcarrier interval. In another embodiment of this disclosure, the resources dedicated to transmitting SSBs corresponding to a Redcap UE can be a first subcarrier interval and / or a second subcarrier interval. In one embodiment of this disclosure, the subcarrier interval for SSB transmission corresponding to a normal UE can be a first subcarrier interval and / or a second subcarrier interval.

[0098] Furthermore, in one embodiment of this disclosure, the aforementioned SSB corresponding to the Redcap UE may be an SSB independently configured by the base station for the Redcap UE.

[0099] In one embodiment of this disclosure, the structure of the SSB corresponding to the Redcap UE is different from the structure of the SSB corresponding to the ordinary UE.

[0100] In one embodiment of this disclosure, the aforementioned "different structure for SSB transmission between Redcap UE and SSB transmission between Redcap UE and ordinary UE" can be manifested as follows: the structure of the SSB corresponding to the Redcap UE is such that the frequency domain resource length of the SSB corresponding to the Redcap UE is less than the frequency domain resource length of the SSB corresponding to the ordinary UE. In some embodiments, the time domain resource length of the SSB corresponding to the Redcap UE can be greater than or equal to the time domain resource length of the SSB corresponding to the ordinary UE. In another embodiment of this disclosure, the frequency domain resource length of the SSB corresponding to the Redcap UE can be less than or equal to the bandwidth range of the Redcap UE.

[0101] Furthermore, in one embodiment of this disclosure, the frequency domain resource length of the newly added time domain resource in the SSB corresponding to the Redcap UE can be less than or equal to the frequency domain resource length in the SSB corresponding to the Redcap UE used to carry the PSS (Primary Synchronization Signal) and / or SSS (Secondary Synchronization Signal). Also, in one embodiment of this disclosure, the number of symbols included in the newly added time domain resource in the SSB corresponding to the Redcap UE can be determined based on the protocol, and / or based on the base station's indication.

[0102] Furthermore, it should be noted that in one embodiment of this disclosure, when the structure of the SSB corresponding to the Redcap UE is different from that of the SSB corresponding to the ordinary UE, the time-frequency domain resource mapping method of the PSS, SSS, and PBCH (Physical Broadcast Channel) in the SSB corresponding to the Redcap UE can be: mapping based on the structure of the SSB corresponding to the Redcap UE.

[0103] In another embodiment of this disclosure, when the structure of the SSB corresponding to the Redcap UE is different from that of the SSB corresponding to the ordinary UE, the time-frequency domain resource mapping method of the PSS, SSS, and PBCH in the SSB corresponding to the Redcap UE can be: mapping based on the structure of the SSB corresponding to the ordinary UE, and mapping the data in the PBCH of the SSB corresponding to the ordinary UE that exceeds the bandwidth range of the Redcap UE to the newly added time-frequency domain resources in the SSB corresponding to the Redcap UE.

[0104] In all embodiments of this disclosure, when the above-mentioned "the structure of the SSB corresponding to the Redcap UE is different from that of the SSB corresponding to the ordinary UE" means that at least one of the PSS, SSS, and PBCH in the SSB corresponding to the Redcap UE is different.

[0105] It should be noted that, when the resources dedicated to transmitting the SSB corresponding to the Redcap UE are in the first subcarrier interval, in one embodiment of this disclosure, the structure of the SSB corresponding to the Redcap UE can be the same as the structure of the SSB corresponding to the ordinary UE. In another embodiment of this disclosure, the structure of the SSB corresponding to the Redcap UE can be different from the structure of the SSB corresponding to the ordinary UE. Furthermore, in one embodiment of this disclosure, when the resources dedicated to transmitting the SSB corresponding to the Redcap UE are in the second subcarrier interval, the structure of the SSB corresponding to the Redcap UE should be different from the structure of the SSB corresponding to the ordinary UE. For a detailed description of "different structure," please refer to the above embodiments.

[0106] Furthermore, in one embodiment of this disclosure, the SSB corresponding to the Redcap UE is offset by N frequency domain positions relative to the synchronization grid position of the SSB corresponding to the ordinary UE; and / or

[0107] The location of time-domain resources for SSB transmission corresponding to Redcap UE is different from that for SSB transmission corresponding to ordinary UE (for example, based on protocol agreements, the two different SSBs can be transmitted on different half-frames, different system frames, or different time slots).

[0108] In one possible implementation, N can be an integer.

[0109] It should be noted that, in one embodiment of this disclosure, the location of the time-domain resources corresponding to the SSB transmission of the Redcap UE can be determined based on the protocol. In another embodiment of this disclosure, the location of the time-domain resources corresponding to the SSB transmission of the Redcap UE can be based on the base station configuration. In yet another embodiment of this disclosure, the location of the time-domain resources corresponding to the SSB transmission of the Redcap UE can be based on the base station indication.

[0110] Furthermore, in one embodiment of this disclosure, the aforementioned N can be determined based on a protocol agreement (e.g., for initial cell search, N can be determined based on a protocol agreement). In another embodiment of this disclosure, the aforementioned N can be determined based on a base station indication (e.g., for RRM measurement, RLM measurement, beam management, etc., N can be determined based on a base station indication).

[0111] Furthermore, examples are provided to illustrate the structure of SSB transmission for Redcap UEs and ordinary UEs. Specifically, Figure 3b This is a schematic diagram of the structure of an SSB corresponding to a normal UE with a subcarrier spacing of 30kHz, provided in an embodiment of this disclosure. Figure 3c-3e This is a schematic diagram of the SSB structure of a Redcap UE with a subcarrier spacing of 30kHz, provided as an embodiment of this disclosure. Of course, the use of 30kHz is merely for illustrative purposes.

[0112] like Figure 3b As shown, the structure of an SSB corresponding to a normal UE with a subcarrier spacing of 30kHz mainly includes PSS, SSS, and PBCH. The time-domain resource length of the SSB corresponding to a normal UE with a subcarrier spacing of 30kHz is 4 symbols, and the frequency-domain resource length is 20 RBs (Resource Blocks). In the frequency domain, PSS and SSS each occupy 12 RBs (including the guard interval), and PBCH occupies 20 RBs. Because the frequency-domain resource length occupied by PBCH in the SSB corresponding to a normal UE with a subcarrier spacing of 30kHz is too long, the total bandwidth of the SSB corresponding to a normal UE with a subcarrier spacing of 30kHz exceeds the bandwidth range of the Redcap UE, making it impossible for the Redcap UE to receive and decode the SSB corresponding to a normal UE with a subcarrier spacing of 30kHz.

[0113] And, comparison Figure 3b and Figure 3c-3e As shown, the frequency domain resource length of the SSB corresponding to the Redcap UE with a subcarrier spacing of 30kHz is 11 RBs, which is less than the frequency domain resource length of the SSB corresponding to the ordinary UE with a subcarrier spacing of 30kHz, which is 20 RBs. The time domain resource length of the SSB corresponding to the Redcap UE with a subcarrier spacing of 30kHz is 6 symbols, which is greater than the time domain resource length of the SSB corresponding to the ordinary UE with a subcarrier spacing of 30kHz, which is 4 symbols.

[0114] Furthermore, it should be noted that in one embodiment of this disclosure, at least one SSB can be transmitted within the same time slot. The transmission positions of different SSBs will be different, thus typically requiring the determination of at least one candidate SSB position, which is the starting transmission position of different SSBs within the same time slot. Based on this, since the time-domain resource length of the SSB corresponding to the Redcap UE is greater than that of the SSB corresponding to the Redcap UE, if the method for determining the candidate SSB position used when transmitting the SSB corresponding to the Redcap UE is still used, it may lead to an overlap of the time-domain resources of the current SSB corresponding to the Redcap UE with the immediately following SSB corresponding to the Redcap UE, thus affecting transmission efficiency. Therefore, it is usually necessary to improve the original method for determining the candidate SSB position (i.e., the method for determining the candidate SSB position corresponding to the ordinary UE).

[0115] Specifically, there are three methods for determining the original SSB candidate location: Case A, Case B, and Case C. Alternatively, one method can be selected from these three methods based on factors such as carrier frequency band and SCS to determine the SSB candidate location. Case A, Case B, and Case C are shown below:

[0116] For a half-frame with an SS / PBCH block, the first symbol index of the candidate SS / PBCH block needs to be determined based on the SCS of the SS / PBCH block. The method for determining the first symbol index of the candidate SS / PBCH block based on the SCS of the SS / PBCH block is as follows, where index 0 corresponds to the first symbol frame of the first time slot in the half-slot.

[0117] Case A: When the SCS subcarrier spacing is 15 kHz, the index of the first symbol of the candidate SS / PBCH block is... .

[0118] In one embodiment of this disclosure, for non-shared spectrum: for carrier frequencies less than or equal to 3 GHz, For carrier frequencies greater than 3 GHz within FR1, .

[0119] Case B: When the SCS subcarrier spacing is 30 kHz, the index of the first symbol of the candidate SS / PBCH block is... .

[0120] In one embodiment of this disclosure, for carrier frequencies less than or equal to 3 GHz, For carrier frequencies greater than 3 GHz within FR1, .

[0121] Case C: When the SCS subcarrier spacing is 30 kHz, the first symbol of the candidate SS / PBCH block has an index. .

[0122] In one embodiment of this disclosure, when using a non-shared spectrum for paired spectrum operation, for carrier frequencies less than or equal to 3 GHz, For carrier frequencies greater than 3 GHz within FR1, .

[0123] Furthermore, in one embodiment of this disclosure, when using non-shared spectrum and for non-paired spectrum operation, for carrier frequencies less than 1.88 GHz, For carrier frequencies within FR1 that are equal to or greater than 1.88 GHz, .

[0124] Referring to the above, when the method for determining the original SSB candidate position is Case B, the starting transmission positions of adjacent SSBs are spaced 4 symbols apart. Based on this, for the structure of an SSB corresponding to a normal UE with a subcarrier spacing of 30kHz, since the time-domain resource length of this SSB corresponding to a normal UE is 4 symbols (refer to...), Figure 3a If the SSBs are positioned such that adjacent SSBs do not overlap in time domain resources, then no overlap in time domain resources will occur between them. However, for the structure of an SSB corresponding to a Redcap UE with a subcarrier spacing of 30kHz, since the time domain resource length of the SSB corresponding to the Redcap UE is greater than that of the SSB corresponding to a normal UE (6 symbols), the time domain resource length of the SSB corresponding to the Redcap UE will be greater than the starting transmission position of the adjacent SSBs determined by Case B, thus causing adjacent SSBs corresponding to the Redcap UE to overlap in time domain resources. Therefore, the Case B method needs to be improved so that the improved Case B will not cause overlap in time domain resources between SSBs corresponding to the Redcap UE. In one embodiment of this disclosure, the improved Case B may include at least one of the following:

[0125] The improved Case B-1 (utilizing...) Figure 3c (The structure determines the candidate SSB position): When the subcarrier spacing is 30 kHz, the index of the first symbol of the candidate SS / PBCH block is {2, 8, 16, 22} + 28*n.

[0126] In one embodiment of this disclosure, for carrier frequencies greater than 3 GHz within FR1, .

[0127] The improved Case B-2 (utilizing...) Figure 3e The structure determines the candidate SSB position: when the subcarrier spacing is 30 kHz, the index of the first symbol of the candidate SS / PBCH block is {3, 8, 16, 22} + 28*n.

[0128] In one embodiment of this disclosure, for carrier frequencies greater than 3 GHz within FR1, .

[0129] Step 302: Receive the SSB resources sent by the base station based on the parameters of the determined SSB resources.

[0130] In one embodiment of this disclosure, the method by which a Redcap UE receives SSB resources sent by a base station based on determined SSB resource parameters may include at least one of the following:

[0131] The first method involves receiving the SSB corresponding to the ordinary UE at a time-frequency domain location corresponding to the SSB of the ordinary UE with a first subcarrier interval. In response to not receiving the SSB corresponding to the ordinary UE, the SSB corresponding to the Redcap UE is received at a time-frequency domain location of the resource dedicated to transmitting the SSB corresponding to the Redcap UE with a first subcarrier interval and / or a second subcarrier interval.

[0132] The second method involves directly receiving the SSB corresponding to the Redcap UE at a first subcarrier interval and / or a second subcarrier interval at the time-frequency domain location of the resource dedicated to transmitting the SSB corresponding to the Redcap UE.

[0133] Regarding the first approach, if SSB reception is performed at the time-frequency domain location corresponding to the SSB of a regular UE, and in response to the receipt of PSS and SSS but unsuccessful PBCH reception, PBCH reception must continue at the time-frequency domain location dedicated to transmitting resources corresponding to the SSB of a Redcap UE. Furthermore, in one embodiment of this disclosure, a possible approach is to perform HARQ merging and decoding on the PBCH in the SSB corresponding to the regular UE and the SSB corresponding to the Redcap UE. Merging requires the PBCH in the SSB corresponding to the Redcap UE to carry the same information bits as the PBCH in the SSB corresponding to the regular UE. Afterward, the UE can determine frame timing based on the time-domain location of the SSB corresponding to the regular UE as the anchor point. Alternatively, in another embodiment of this disclosure, HARQ merging is not performed. In this case, the content of the PBCH corresponding to the Redcap UE can be the same as or different from the content of the PBCH corresponding to the regular UE. In one embodiment, if the frames are the same, the frame timing determination method is as follows: the UE determines the frame timing using the time domain position of the SSB corresponding to the ordinary UE as the anchor point. In another embodiment, if the frames are different, the frame timing is determined using the time domain position of the dedicated SSB corresponding to the Redcap UE as the anchor point.

[0134] Furthermore, it should be noted that, in one embodiment of this disclosure, the specific time-domain location at which the Redcap UE receives the SSB corresponding to the Redcap UE using a first subcarrier interval, a second subcarrier interval, or both a first subcarrier interval and a second subcarrier interval, can be determined based on the carrier frequency band, the base station configuration and / or indication, or the protocol agreement.

[0135] Specifically, in one embodiment of this disclosure, for the SSB corresponding to the Redcap UE used in the initial cell search, the subcarrier spacing of the SSB corresponding to the Redcap UE can be determined based on the carrier frequency band. Specifically, for a carrier frequency band that only supports a first subcarrier spacing, the first subcarrier spacing can be used to receive the SSB corresponding to the Redcap UE; for a carrier frequency band that only supports a second subcarrier spacing, the second subcarrier spacing can be used to receive the SSB corresponding to the Redcap UE; for a carrier frequency band that supports both the first and second subcarrier spacings, the first and / or second subcarrier spacings can be used for frequency scanning to receive the SSB corresponding to the Redcap UE.

[0136] Furthermore, in one embodiment of this disclosure, for an SSB corresponding to a Redcap UE used in RRM measurement, and / or RLM measurement, and / or SSB management, and / or SSB synchronization after cell access, the subcarrier spacing used when receiving an SSB corresponding to a Redcap UE can be determined based on the base station configuration and / or indication.

[0137] In another embodiment of this disclosure, based on a protocol agreement, the UE can always receive the SSB corresponding to the Redcap UE at a time-domain location with a first subcarrier interval in any frequency band at a time-domain location dedicated to transmitting the SSB corresponding to the Redcap UE.

[0138] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCH transmitted by the base station on the new time-frequency domain resource. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0139] Figure 4 This is a flowchart illustrating an information transmission method provided in yet another embodiment of this disclosure, applied to a Redcap UE, such as... Figure 4 As shown, the information transmission method may include the following steps:

[0140] Step 401: Determine the parameters for the SSB resources used to transmit the Redcap UE.

[0143] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the Redcap UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCH transmitted by the base station on the new time-frequency domain resource. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0144] Figure 5 This is a flowchart illustrating an information transmission method provided in yet another embodiment of this disclosure, applied to a Redcap UE, such as... Figure 5 As shown, the information transmission method may include the following steps:

[0145] Step 501: Determine the parameters for the SSB resources used to transmit the Redcap UE. The parameters for the SSB resources used to transmit the Redcap UE include resources dedicated to transmitting the SSB corresponding to the Redcap UE. The resources dedicated to transmitting the SSB corresponding to the Redcap UE are resources of the first subcarrier interval and / or the second subcarrier interval.

[0146] Step 502: Receive the SSB resources sent by the base station based on the parameters of the determined SSB resources.

[0147] For a detailed description of steps 501-502 above, please refer to the above embodiments. This disclosure will not repeat the details here.

[0148] In summary, in the information transmission method provided in this embodiment, the Redcap UE can receive SSBs according to a first subcarrier interval; and / or, the Redcap UE can receive PBCHs transmitted by the base station in the new time-frequency domain resources. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resources is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCHs transmitted by the base station in the new time-frequency domain resources. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive SSBs with the first subcarrier interval, and / or PBCHs transmitted by the base station in the new time-frequency domain resources, thus improving transmission stability.

[0149] Figure 6 This is a flowchart illustrating an information transmission method provided in yet another embodiment of this disclosure, applied to a Redcap UE, such as... Figure 6 As shown, the information transmission method may include the following steps:

[0150] Step 601: Determine the parameters of the SSB resources used for transmitting the Redcap UE. The parameters of the synchronization signal block SSB resources used for transmitting the Redcap UE include the parameters of the PBCH dedicated to transmitting the SSB of the Redcap UE.

[0151] In one embodiment of this disclosure, the parameters of the PBCH of the SSB dedicated to transmitting Redcap UE may include:

[0152] The time-frequency domain resources corresponding to the Redcap UE for transmitting PBCH are at least two parts, wherein the frequency domain resource length of each part of the time-frequency domain resources is less than or equal to the bandwidth range of the Redcap UE, and the frequency domain resource length of each part of the time-frequency domain resources is less than the frequency domain resource length of the time-frequency domain resources corresponding to the ordinary UE for transmitting PBCH.

[0153] or

[0154] Time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, wherein the length of the frequency domain resources dedicated to transmitting the time-frequency domain resources corresponding to the PBCH of the Redcap UE is less than or equal to the bandwidth range of the Redcap UE.

[0155] Detailed descriptions of the above-mentioned content will be provided in subsequent embodiments.

[0156] Step 602: Receive the SSB resources sent by the base station based on the parameters of the determined SSB resources.

[0157] In one embodiment of this disclosure, when the parameters of the PBCH for the SSB dedicated to transmitting Redcap UE are determined in step 601 above are different, the method for receiving SSB resources sent by the base station in this step will also be different, and this part will be described in detail in subsequent embodiments.

[0158] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCH transmitted by the base station on the new time-frequency domain resource. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0159] Figure 7a This is a flowchart illustrating an information transmission method provided in yet another embodiment of this disclosure, applied to a Redcap UE, such as... Figure 7a As shown, the information transmission method may include the following steps:

[0160] Step 701a: Determine the parameters of the synchronization signal block SSB resources used for transmitting the Redcap UE. The parameters of the synchronization signal block SSB resources used for transmitting the Redcap UE include at least two portions of time-frequency domain resources corresponding to the Redcap UE for transmitting the PBCH.

[0161] In one embodiment of this disclosure, the frequency domain resource length of each portion of the time-frequency domain resources is less than or equal to the bandwidth range of the Redcap UE, and the frequency domain resource length of each portion of the time-frequency domain resources is less than the frequency domain resource length of the time-frequency domain resources used for transmitting PBCH corresponding to a normal UE.

[0162] Specifically, in one embodiment of this disclosure, the above-mentioned at least two portions of time-frequency domain resources corresponding to the Redcap UE for transmitting PBCH may include: a first portion of resources and a second portion of resources;

[0163] The first part of the resources is the time-frequency domain resources corresponding to the SSB of a normal UE, which are used to transmit data in the PBCH of the SSB of a normal UE that does not exceed the bandwidth range of the Redcap UE.

[0164] This second part of the resources may be different from the time-frequency domain resources corresponding to the SSB of a normal UE, and is used to transmit data in the PBCH of the SSB of a normal UE that exceeds the bandwidth range of the Redcap UE.

[0165] Step 702a: In response to the subcarrier spacing of the SSB corresponding to the ordinary UE being the second subcarrier spacing, receive the PSS, SSS in the SSB corresponding to the ordinary UE at the synchronization grid position of the SSB corresponding to the ordinary UE, and receive data in the PBCH of the SSB corresponding to the ordinary UE that does not exceed the bandwidth range of the Redcap UE in the first part of the resources, and receive data in the PBCH of the SSB corresponding to the ordinary UE that exceeds the bandwidth range of the Redcap UE in the second part of the resources, wherein the second part of the resources is the first symbol before and / or after the time-frequency domain resources of the SSB corresponding to the ordinary UE.

[0166] In one embodiment of this disclosure, the frequency domain resource length of the first symbol may be less than or equal to the bandwidth range of the Redcap UE.

[0167] Furthermore, an example of the receiving method in step 702a will be provided. Figure 7b , 7c Figures 7d and 7d are schematic diagrams illustrating the structure of an SSB corresponding to a Redcap UE sent in step 702a, provided in an embodiment of this disclosure. Figure 7b , 7cAs shown in Figures 7d and 7d, the PSS and SSS in the SSB corresponding to the Redcap UE are still transmitted at the synchronization grid position of the SSB corresponding to the normal UE. Data in the PBCH of the SSB corresponding to the Redcap UE that does not exceed the bandwidth range of the Redcap UE (i.e., the PBCH data not shaded in the figure) is transmitted on the first part of the resources (the synchronization grid position when data transmission in the SSB corresponding to the normal UE does not exceed the bandwidth range of the Redcap UE). Furthermore, data in the PBCH of the SSB corresponding to the normal UE that exceeds the bandwidth range of the Redcap UE (i.e., the PBCH data shaded in the figure) is transmitted before and / or after the first symbol of the time-frequency domain resources corresponding to the normal UE.

[0168] Among them, reference Figure 7b It can be seen that data exceeding the bandwidth range of a Redcap UE in the PBCH of the SSB corresponding to a normal UE is transmitted as the first symbol after the time-frequency domain resources of the SSB corresponding to the normal UE. (See reference...) Figure 7c It can be seen that data exceeding the bandwidth range of a Redcap UE in the PBCH of the SSB corresponding to a normal UE is transmitted in the first symbol before the time-frequency domain resources of the SSB corresponding to the normal UE. (Reference) Figure 7d It can be seen that data exceeding the bandwidth range of the Redcap UE in the PBCH of the SSB corresponding to the ordinary UE is transmitted before and after the first symbol in the time-frequency domain resources of the SSB corresponding to the ordinary UE.

[0169] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCH transmitted by the base station on the new time-frequency domain resource. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0170] Figure 8a This is a flowchart illustrating an information transmission method provided in yet another embodiment of this disclosure, applied to a Redcap UE, such as... Figure 8aAs shown, the information transmission method may include the following steps:

[0171] Step 801a: Determine the parameters of the synchronization signal block SSB resources used for transmitting the Redcap UE. The parameters of the synchronization signal block SSB resources used for transmitting the Redcap UE include at least two portions of time-frequency domain resources corresponding to the Redcap UE for transmitting the PBCH.

[0172] In one embodiment of this disclosure, the frequency domain resource length of each portion of the time-frequency domain resources is less than or equal to the bandwidth range of the Redcap UE, and the frequency domain resource length of each portion of the time-frequency domain resources is less than the frequency domain resource length of the time-frequency domain resources used for transmitting PBCH corresponding to a normal UE.

[0173] Specifically, in one embodiment of this disclosure, the above-mentioned at least two portions of time-frequency domain resources corresponding to the Redcap UE for transmitting PBCH may include: a first portion of resources and a second portion of resources;

[0174] The first part of the resources is the time-frequency domain resources corresponding to the SSB of a normal UE, which are used to transmit data in the PBCH of the SSB of a normal UE that does not exceed the bandwidth range of the Redcap UE.

[0175] This second part of the resources may be different from the time-frequency domain resources corresponding to the SSB of a normal UE, and is used to transmit data in the PBCH of the SSB of a normal UE that exceeds the bandwidth range of the Redcap UE.

[0176] Step 802a: In response to the subcarrier spacing of the SSB corresponding to the ordinary UE being the second subcarrier spacing, the PSS, SSS of the SSB corresponding to the ordinary UE, and data in the PBCH of the SSB corresponding to the ordinary UE that do not exceed the bandwidth range of the Redcap UE are received at the synchronization grid position of the SSB corresponding to the ordinary UE. Based on radio frequency retuning technology, data in the PBCH of the SSB corresponding to the ordinary UE that exceed the bandwidth range of the Redcap UE are received in the second part of the resources, wherein the frequency domain position of the second part of the resources is different from that of the first part of the resources.

[0177] The receiving method in step 802a is illustrated with an example. Figure 8b and 8c This is a schematic diagram of the structure of the SSB corresponding to the Redcap UE sent in step 802a, provided as an embodiment of this disclosure. Figure 8b and 8cAs shown, the PSS and SSS in the SSB corresponding to the Redcap UE are still transmitted at the synchronization grid position corresponding to the SSB of the normal UE. Data in the PBCH of the SSB corresponding to the Redcap UE that does not exceed the bandwidth range of the Redcap UE (i.e., the PBCH data not shaded in the figure) is transmitted on the first part of the resources (the synchronization grid position when data transmission in the SSB of the normal UE does not exceed the bandwidth range of the Redcap UE). Furthermore, data in the PBCH of the SSB corresponding to the normal UE that exceeds the bandwidth range of the Redcap UE (i.e., the PBCH data shaded in the figure) is received in the second part of the resources based on radio frequency readjustment technology.

[0178] The frequency division multiplexing method for the second part of resources and the first part of resources can be, for example, as follows: Figure 8b or Figure 8c As shown.

[0179] Furthermore, in one embodiment of this disclosure, when data exceeding the bandwidth range of a Redcap UE in the PBCH of an SSB corresponding to a normal UE is received in the second part of the resources via radio frequency retuning technology, the UE needs to first determine the time-domain interval and frequency-domain interval of the second part of the resources compared to the first part of the resources to ensure successful reception of data exceeding the bandwidth range of a Redcap UE in the PBCH of an SSB corresponding to a normal UE.

[0180] In one embodiment of this disclosure, the method for determining the frequency division multiplexing time interval and frequency domain interval may include:

[0181] The time-domain and frequency-domain intervals in frequency division multiplexing are determined based on the agreement; and / or

[0182] The time-domain and frequency-domain intervals in frequency division multiplexing are determined based on the base station configuration; and / or

[0183] The time-domain interval and frequency-domain interval in frequency division multiplexing are determined based on base station indications.

[0184] Furthermore, it should be noted that in one embodiment of this disclosure, the Redcap UE performs radio frequency readjustment, that is, adjusts the center frequency of the radio frequency bandwidth from the center frequency of the first part of the resources to the center frequency of the second part of the resources, which takes a certain amount of time. Based on this, the transmission between the data in the PSS, SSS, and PBCH of the SSB of the ordinary UE that does not exceed the bandwidth range of the Redcap UE and the data in the PBCH of the SSB of the ordinary UE that exceeds the bandwidth range of the Redcap UE needs to have a guard interval (e.g., Figure 8b and Figure 8c(as shown by the guard symbol). When the Redcap UE receives data from the PSS, SSS, and PBCH of the SSB corresponding to the ordinary UE that does not exceed the Redcap UE's bandwidth range, it has sufficient time to adjust the center frequency of the radio frequency bandwidth from the center frequency of the first part of the resources to the center frequency of the second part of the resources. This allows subsequent reception of data exceeding the Redcap UE's bandwidth range in the PBCH of the SSB corresponding to the ordinary UE, based on radio frequency readjustment.

[0185] Furthermore, it should be noted that when the second portion of resources and the first portion of resources are frequency-division multiplexed, in one embodiment of this disclosure, the subcarrier spacing of the first portion of resources may be the same as the subcarrier spacing of the second portion of resources. In another embodiment of this disclosure, the subcarrier spacing of the first portion of resources may be different from the subcarrier spacing of the second portion of resources.

[0186] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCH transmitted by the base station on the new time-frequency domain resource. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0187] Figure 9a This is a flowchart illustrating an information transmission method provided in yet another embodiment of this disclosure, applied to a Redcap UE, such as... Figure 9a As shown, the information transmission method may include the following steps:

[0188] Step 901a: Determine the parameters of the synchronization signal block SSB resources used for transmitting the Redcap UE. The parameters of the synchronization signal block SSB resources used for transmitting the Redcap UE include at least two portions of time-frequency domain resources corresponding to the Redcap UE for transmitting the PBCH.

[0189] In one embodiment of this disclosure, the frequency domain resource length of each portion of the time-frequency domain resources is less than or equal to the bandwidth range of the Redcap UE, and the frequency domain resource length of each portion of the time-frequency domain resources is less than the frequency domain resource length of the time-frequency domain resources used for transmitting PBCH corresponding to a normal UE.

[0190] Specifically, in one embodiment of this disclosure, the above-mentioned at least two portions of time-frequency domain resources corresponding to the Redcap UE for transmitting PBCH may include: a first portion of resources and a second portion of resources;

[0191] The first part of the resources is the time-frequency domain resources corresponding to the SSB of a normal UE, which are used to transmit data in the PBCH of the SSB of a normal UE that does not exceed the bandwidth range of the Redcap UE.

[0192] This second part of the resources may be different from the time-frequency domain resources corresponding to the SSB of a normal UE, and is used to transmit data in the PBCH of the SSB of a normal UE that exceeds the bandwidth range of the Redcap UE.

[0193] Step 902a: In response to the subcarrier spacing corresponding to the SSB of the ordinary UE being the second subcarrier spacing, at the synchronization grid position of the SSB corresponding to the ordinary UE, receive the PSS, SSS in the SSB corresponding to the ordinary UE, and receive data in the PBCH of the SSB corresponding to the ordinary UE that does not exceed the bandwidth range of the Redcap UE in the first part of the resources, and receive the first part of the data in the PBCH of the SSB corresponding to the ordinary UE that exceeds the bandwidth range of the Redcap UE on a part of the resources in the second part of the resources, and receive the second part of the data in the PBCH of the SSB corresponding to the ordinary UE that exceeds the bandwidth range of the Redcap UE on another part of the resources in the second part of the resources based on radio frequency retuning technology.

[0194] In one embodiment of this disclosure, a portion of the resources in the second part may be the first symbol before and / or after the time-frequency domain resources of the SSB corresponding to a normal UE, and the other portion of the resources in the second part may be frequency-division multiplexed with the first part of the resources.

[0195] The receiving method in step 902a is illustrated with an example. Figure 9b-9g This is a schematic diagram of the structure of an SSB corresponding to a Redcap UE sent in step 902a, provided as an embodiment of this disclosure.

[0196] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCH transmitted by the base station on the new time-frequency domain resource. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0197] Figure 10a This is a flowchart illustrating an information transmission method provided in yet another embodiment of this disclosure, applied to a Redcap UE, such as... Figure 10a As shown, the information transmission method may include the following steps:

[0198] Step 1001a: Determine the parameters for transmitting the synchronization signal block SSB resources of the Redcap UE. The parameters for transmitting the synchronization signal block SSB resources of the Redcap UE include time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE.

[0199] In one embodiment of this disclosure, the length of the frequency domain resource dedicated to transmitting the time-frequency domain resource corresponding to the PBCH of the Redcap UE is less than or equal to the bandwidth range of the Redcap UE.

[0200] Step 1002a: In response to the subcarrier spacing of the SSB corresponding to the ordinary UE being the second subcarrier spacing, receive the PSS, SSS, and data in the PBCH within the bandwidth range of the Redcap UE in the SSB corresponding to the ordinary UE at the synchronization grid position of the SSB corresponding to the ordinary UE, and receive all PBCH information in the SSB corresponding to the ordinary UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE.

[0201] In one embodiment of this disclosure, the information bits carried by the PBCH at the synchronization grid position of the SSB of a normal UE are the same as the information bits carried by the PBCH on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE. The PBCH data received by the Redcap UE at the synchronization grid position of the original SSB and the PBCH data received by the Redcap UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE are merged (for example, HARQ (Hybrid Automatic Repeat request) merging). Downlink synchronization and frame timing are then performed based on the symbol position of the PSS and / or SSS as the anchor point.

[0202] In another embodiment of this disclosure, the information bits carried by the PBCH at the synchronization grid position of the original SSB are different from the information bits carried by the PBCH on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE. HARQ combining is not performed, and downlink synchronization and frame timing are performed based on the time-domain position of the PBCH dedicated to transmitting the PBCH corresponding to the Redcap UE as the anchor point.

[0203] It should be noted that, in one embodiment of this disclosure, if the UE first receives data in the PBCH within the bandwidth range of the Redcap UE at the synchronization grid position of the SSB corresponding to the ordinary UE, it can attempt to decode the received PBCH data. If the decoding is successful, the UE can stop receiving data on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE.

[0204] In one embodiment of this disclosure, after the UE receives data in the PBCH within the bandwidth range of the Redcap UE at the synchronization grid position of the SSB corresponding to the ordinary UE, it may not decode the received PBCH data. Instead, after receiving the data on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, it may merge the PBCH data received by the Redcap UE at the synchronization grid position of the original SSB with the PBCH data received by the Redcap UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE.

[0205] In one embodiment of this disclosure, if the UE first receives all the PBCH information in the SSB corresponding to the ordinary UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, it can attempt to decode the received PBCH data. If the decoding is successful, it can receive the data in the PBCH within the bandwidth range of the Redcap UE without receiving it at the synchronization grid position of the SSB corresponding to the ordinary UE.

[0206] In one embodiment of this disclosure, after the UE receives all the PBCH information in the SSB corresponding to the ordinary UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, it may not decode the received PBCH data. Instead, it may receive the data in the PBCH within the bandwidth range of the Redcap UE at the synchronization grid position of the SSB corresponding to the ordinary UE, and then merge the PBCH data received by the Redcap UE at the synchronization grid position of the original SSB with the PBCH data received by the Redcap UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE.

[0207] Furthermore, it should be noted that, in one embodiment of this disclosure, the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE can be the first symbol before and / or after the time-frequency domain resources corresponding to the SSB of the ordinary UE. Therefore, the method for receiving all PBCH information in the SSB corresponding to the ordinary UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE can include: receiving all PBCH information in the SSB corresponding to the ordinary UE on the first symbol.

[0208] in, Figure 10b and Figure 10c This is a schematic diagram illustrating the structure of an SSB corresponding to a Redcap UE obtained when receiving all PBCH information in an SSB corresponding to a normal UE on a first symbol, as provided in an embodiment of this disclosure. Figure 10b and Figure 10c As shown in the figure, all the New PBCHs correspond to all the PBCH information in the SSB of a normal UE. Figure 10b In this process, all PBCH information in the SSB corresponding to the ordinary UE is transmitted on the first symbol preceding the time-frequency domain resources of the SSB corresponding to the ordinary UE. Figure 10c In this process, all PBCH information in the SSB corresponding to the ordinary UE is transmitted on the first symbol following the time-frequency domain resources of the SSB corresponding to the ordinary UE.

[0209] In another embodiment of this disclosure, receiving all PBCH information in the SSB corresponding to a normal UE on time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE may include:

[0210] Based on radio frequency readjustment technology, all PBCH information in the SSB corresponding to a normal UE is received on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE. The time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE are frequency-division multiplexed with the time-frequency domain resources corresponding to the SSB of the normal UE.

[0211] in, Figure 10d and Figure 10e This is a schematic diagram illustrating the structure of an SSB corresponding to a Redcap UE obtained when receiving all PBCH information from an SSB corresponding to a normal UE based on radio frequency readjustment technology, as provided in an embodiment of this disclosure. Figure 10d and Figure 10e As shown in the figure, all the New PBCHs in the diagram correspond to all the PBCH information in the SSB of a normal UE. The frequency division multiplexing method for the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE and the time-frequency domain resources corresponding to the SSB of the normal UE can be as follows: Figure 10d and Figure 10e As shown.

[0212] In yet another embodiment of this disclosure, the method described above for receiving all PBCH information in the SSB corresponding to a normal UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE may include:

[0213] The first part receives all PBCH information in the SSB corresponding to a normal UE on a portion of the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, and the second part receives all PBCH information in the SSB corresponding to the normal UE on another portion of the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, based on radio frequency remodulation technology.

[0214] Specifically, a portion of the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE are the first symbols before and / or after the time-frequency domain resources of the SSB corresponding to the ordinary UE, and the other portion of the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE are frequency-division multiplexed with the time-frequency domain resources of the SSB corresponding to the ordinary UE.

[0215] as well as, Figure 10f and Figure 10gThis is a schematic diagram of the structure of an SSB corresponding to a Redcap UE obtained when receiving all PBCH information in an SSB corresponding to a normal UE based on a first symbol and radio frequency remodulation technology, according to an embodiment of this disclosure.

[0216] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource. The first subcarrier interval satisfies the following: when the SSB uses the first subcarrier interval, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE; that is, when the subcarrier interval of the SSB is the first subcarrier interval, the UE can successfully receive and decode the SSB. Furthermore, the frequency domain resource length of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE; that is, regardless of the subcarrier interval corresponding to the SSB of a normal UE, the UE can always successfully receive the PBCH transmitted by the base station on the new time-frequency domain resource. Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0222] Furthermore, it should be noted that in one embodiment of this disclosure, when the data carried on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE is the same as the information bits of the data in the PBCH of the SSB corresponding to the ordinary UE, the downlink frame timing can be performed using the time-domain position of the SSB corresponding to the ordinary UE as the anchor point.

[0223] In another embodiment of this disclosure, when the data carried on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE is different from the information bits of the data in the PBCH in the SSB corresponding to the ordinary UE (such as when the SFN, half-frame indication information, etc. in the PBCH data are different), the downlink frame timing can be performed using the time domain position of the PBCH in the SSB corresponding to the Redcap UE as the anchor point.

[0224] In summary, in the information transmission method provided in this embodiment, the UE can receive SSB according to a first subcarrier interval; and / or, the UE can determine a new time-frequency domain resource and receive the PBCH transmitted by the base station on the new time-frequency domain resource.

Therefore, the information transmission method provided in this embodiment can ensure that the UE can successfully receive the SSB with the first subcarrier interval, and / or the PBCH transmitted by the base station on the new time-frequency domain resource, thus improving transmission stability.

[0225] Furthermore, it should be noted that which specific embodiment the Redcap UE uses to receive SSB resources sent by the base station can be determined based on base station indication and / or, based on the protocol. Also, in one embodiment of this disclosure, for SSB co-frequency transmission without radio frequency readjustment, the newly added time-domain resources in the SSB corresponding to the Redcap UE can have a certain number of interval symbols between them and the symbols in the SSB corresponding to the ordinary UE. The specific number of these interval symbols can be determined based on the protocol and / or, based on base station indication.
