Description

Information transmission method and equipment/storage medium/device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an information transmission method and apparatus/storage medium/device.

Background

In 3gpp r18 (Release 18), the capability user equipment is reduced by introducing a Redcap UE (Reduced Capability User Equipment) to reduce transmission costs.

In the related art, the maximum bandwidth of the Redcap UE is 5MHZ (Hertz). However, SCS (Sub-Carrier Space) of SSB (Synchronization Signal and PBCH block, synchronization signal block) includes 15KHz and 30KHz and other frequency values, and reference may be made to 3GPP related standards in particular. For the Redcap UE, when the subcarrier spacing of the SSB is 30KHz, the total bandwidth occupied by the SSB is 7.2MHZ, which exceeds the bandwidth range of the Redcap UE, which results in failure of the Redcap UE to decode the MIB (Master information block ) message successfully, so that SSB transmission with subcarrier spacing of 30KHz or higher fails.

Fig. 1 is a flow chart of an information transmission method provided by an embodiment of the present disclosure, which is applied to a Redcap UE, as shown in fig. 1, and the information transmission method may include the following steps:

step 101, determining parameters for transmitting SSB resources of the Redcap UE.

It is noted that in one embodiment of the present disclosure, a UE may be a device that provides voice and/or data connectivity to a user. The terminal device may communicate with one or more core networks via a RAN (Radio Access Network ), and the UE may be an internet of things terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an internet of things terminal, e.g., a fixed, portable, pocket, hand-held, computer-built-in, or vehicle-mounted device. Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile), remote Station (remote Station), access point, remote terminal (remote), access terminal (access terminal), user device (user terminal), or user agent (user agent). Alternatively, the UE may be a device of an unmanned aerial vehicle. Alternatively, the UE may be a vehicle-mounted device, for example, a laptop with a wireless communication function, or a wireless terminal externally connected to the laptop. Alternatively, the UE may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices with a wireless communication function.

In one embodiment of the present disclosure, the above-mentioned Redcap UE may specifically be a Redcap UE applied in Release 18 version. The bandwidth range of the maximum Recap UE supported by the Recap UE is 5MHz. And, in one embodiment of the present disclosure, based on protocol specifications, a cell supporting Redcap UE access may perform one or more functions of downlink synchronization, initial cell search, RRM (Radio Resource Management ) measurement, radio link monitoring (radio link monitoring, RLM) measurement, beam management, etc. with SSBs that fixedly transmit scs=15 KHZ. A cell that does not support Redcap UE access may perform one or more functions of downlink synchronization, initial cell search, RRM measurement, RLM measurement, beam management, etc., using SSB with scs=30 KHZ.

And, in one embodiment of the present disclosure, the bandwidth of the SSB resource for transmitting the Redcap UE may be less than or equal to the bandwidth range of the Redcap UE, so that it may be ensured that the transmitted SSB resource is always successfully received and decoded by the Redcap UE.

Further, in one embodiment of the present disclosure, the parameters for transmitting SSB resources of the Redcap UE may include: parameters corresponding to SSB of transmitting Redcap UE; or, parameters of PBCH dedicated to transmission of SSB of Redcap UE.

Among other things, in one embodiment of the present disclosure, the parameters corresponding to SSB of a transmitting Redcap UE may include:

resources corresponding to a first subcarrier spacing of SSBs transmitting the Redcap UE, wherein a bandwidth of the resources for transmitting the SSBs is less than or equal to a bandwidth range of the Redcap UE;

or (b)

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

In one embodiment of the present disclosure, the SSB corresponding to the Redcap UE may be an SSB configured by the base station independently for the Redcap UE. Also, the structure of the SSB corresponding to the Redcap UE may be different from that of the SSB corresponding to the normal UE, wherein the normal UE may be a non-Redcap UE and/or a Redcap UE in Release 17, and the structure of the SSB corresponding to the Redcap UE will be described in detail in the following embodiments.

Further, in one embodiment of the present disclosure, the above-described resources dedicated to transmitting SSBs corresponding to Redcap UEs may correspond to the first subcarrier spacing. In another embodiment of the present disclosure, the above-described resources dedicated to transmitting SSBs corresponding to the Redcap UE may correspond to the first subcarrier spacing and/or the second subcarrier spacing.

In one embodiment of the disclosure, the first subcarrier spacing may be a subcarrier spacing in which rdecapeue can receive the complete SSB, or a subcarrier spacing in which redcap ue can receive the PBCH in the SSB; for example, the first subcarrier spacing may be 15KHZ. The second subcarrier spacing may be any subcarrier spacing other than the first subcarrier spacing. For example, the second subcarrier spacing may be 30KHZ to 240KHZ; over these subcarrier spacings, rdecasue cannot receive the complete SSB, or rdecasue cannot receive the PBCH in the SSB.

In all embodiments of the present disclosure, specific values of the first subcarrier spacing, the second subcarrier spacing are not specifically limited; those skilled in the art will appreciate that: the first subcarrier interval is a subcarrier interval of which Rdecapue can receive the complete SSB in the related art or a subcarrier interval of which RedCapUE can receive the PBCH of the SSB in the related art; the second subcarrier spacing may be any subcarrier spacing other than the first subcarrier spacing.

Still further, the above parameters of the PBCH dedicated to transmitting the SSB of the Redcap UE may include:

at least two parts of time-frequency domain resources for transmitting the PBCH corresponding to the Redcap UE, wherein the frequency domain resource length of each part of time-frequency domain resources is smaller than or equal to the bandwidth range of the Redcap UE, and the frequency domain resource length of each part of time-frequency domain resources is smaller than the frequency domain resource length of the time-frequency domain resources for transmitting the PBCH corresponding to the common UE;

Or (b)

And transmitting the time-frequency domain resource of the PBCH corresponding to the Redcap UE, wherein the length of the frequency domain resource of the time-frequency domain resource of the PBCH corresponding to the Redcap UE is less than or equal to the bandwidth range of the Redcap UE.

Step 102, receiving SSB resources sent by the base station based on the determined parameters of the SSB resources.

In one embodiment of the present disclosure, when the parameters of the SSB resources determined in step 102 are different, the method for receiving the SSB resources sent by the base station by the Redcap UE is also different. This part of the content will be described in detail in the following examples.

In summary, in the information transmission method provided in the embodiments of the present disclosure, the UE may receive the SSB according to the first subcarrier interval; and/or the UE may determine a new time-frequency domain resource and receive a PBCH transmitted by the base station at the new time-frequency domain resource. Wherein, the first subcarrier spacing satisfies: when the SSB uses the first subcarrier spacing, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE, that is, when the subcarrier spacing of the SSB is the first subcarrier spacing, the UE can successfully receive and decode the SSB. And the length of the frequency domain resource of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE, that is, the UE can always successfully receive the PBCH sent by the base station by the new time-frequency domain resource no matter what subcarrier interval corresponds to the SSB of the common UE. As can be seen, the information transmission method provided by the embodiment of the present disclosure may ensure that the UE can successfully receive the SSB of the first subcarrier interval, and/or the PBCH sent by the base station in the new time-frequency domain resource, so that the transmission stability is improved.

Fig. 2 is a flow chart of an information transmission method according to another embodiment of the present disclosure, which is applied to a Redcap UE, as shown in fig. 2, and the information transmission method may include the following steps:

step 201, determining a parameter of SSB resources for transmitting the Redcap UE, where the parameter of SSB resources for transmitting the Redcap UE includes resources corresponding to a first subcarrier spacing for transmitting SSB of the Redcap UE, and a bandwidth of the resources for transmitting SSB is less than or equal to a bandwidth range of the Redcap UE.

Wherein, in one embodiment of the present disclosure, the first subcarrier spacing may be, for example, 15KHZ.

Step 202, receiving SSB resources transmitted by a base station at a first subcarrier spacing.

Fig. 3a is a flow chart of an information transmission method according to still another embodiment of the present disclosure, which is applied to a Redcap UE, as shown in fig. 3a, and the information transmission method may include the following steps:

step 301a, determining parameters for transmitting SSB resources of the Redcap UE, the parameters for transmitting SSB resources of the Redcap UE including resources dedicated to transmitting SSBs corresponding to the Redcap UE.

Wherein, in one embodiment of the present disclosure, the resource dedicated to transmitting SSB corresponding to the Redcap UE may be the first subcarrier spacing. In another embodiment of the present disclosure, the resources dedicated to transmitting SSBs corresponding to the Redcap UE may be a first subcarrier spacing and/or a second subcarrier spacing. In one embodiment of the present disclosure, the subcarrier spacing at the time of SSB transmission corresponding to the general UE may be the first subcarrier spacing and/or the second subcarrier spacing.

And, in one embodiment of the present disclosure, the SSB corresponding to the Redcap UE described above may be an SSB configured independently by the base station for the Redcap UE.

Among other things, in one embodiment of the present disclosure, the structure of the SSB corresponding to the Redcap UE is different from the structure of the SSB corresponding to the normal UE.

Among them, in one embodiment of the present disclosure, the above-described "SSB corresponding to the Redcap UE is different from the SSB corresponding to the normal UE in structure at the time of transmission" may be embodied as: the SSB structure corresponding to the Redcap UE is: the frequency domain resource length of the SSB corresponding to the Redcap UE is smaller than that of the SSB corresponding to the normal UE. In some embodiments, the time domain resource length of the SSB corresponding to the Redcap UE may be greater than or equal to the time domain resource length of the SSB of the normal UE. Wherein, in one embodiment of the present disclosure, the frequency domain resource length of the SSB corresponding to the Redcap UE may be less than or equal to the bandwidth range of the Redcap UE.

And, in one embodiment of the present disclosure, the frequency domain resource length of the time domain resource newly added in the SSB corresponding to the Redcap UE may be less than or equal to the frequency domain resource length used for carrying PSS (Primary Synchronization Signal ) and/or SSS (SecondarySynchronization Signal, secondary synchronization signal) in the SSB corresponding to the Redcap UE. Meanwhile, in one embodiment of the present disclosure, the number of symbols included in the time domain resource newly added in the SSB corresponding to the Redcap UE may be determined based on a protocol and/or based on an indication of the base station.

In addition, it should be noted that, in one embodiment of the present disclosure, when the above-mentioned "SSB corresponding to the Redcap UE is different from the SSB corresponding to the normal UE in structure during transmission", the above-mentioned time-frequency domain resource mapping manner of PSS, SSS, PBCH (Physical Broadcast Channel ) in the SSB corresponding to the Redcap UE may be: mapping is based on the structure of SSBs corresponding to the Redcap UEs.

In another embodiment of the present disclosure, when the above-mentioned SSB corresponding to the Redcap UE is different from the SSB corresponding to the normal UE in the structure at the time of SSB transmission, the above-mentioned time-frequency domain resource mapping manner of PSS, SSS, PBCH in the SSB corresponding to the Redcap UE may be: mapping is performed based on the structure of the SSB corresponding to the normal UE, and data exceeding the bandwidth range of the Redcap UE in the PBCH of the SSB corresponding to the normal UE is mapped onto the newly added time-frequency domain resources in the SSB corresponding to the Redcap UE.

In all embodiments of the present disclosure, the above-described "the structure is different when SSB corresponding to the Redcap UE is transmitted from SSB corresponding to the normal UE" means that at least one among PSS, SSS, PBCH of the above-described SSBs corresponding to the Redcap UE is different.

It should be noted that, when the above-mentioned resource dedicated to transmitting the SSB corresponding to redcapeue is the first subcarrier spacing, in one embodiment of the present disclosure, the structure of the SSB corresponding to redcapeue may be the same as the structure of the SSB corresponding to the general UE. In another embodiment of the present disclosure, the structure of the SSB corresponding to redcam UE may be different from the structure of the SSB corresponding to general UE. And, in one embodiment of the present disclosure, when the above-mentioned resources dedicated to transmitting SSBs corresponding to redcapeue are the second subcarrier spacing, the structure of the SSBs corresponding to redcapeue should be different from the structure of the SSBs corresponding to general UEs. Wherein the detailed description of the "structurally different" can be described with reference to the above embodiments.

Further, in one embodiment of the present disclosure, the SSB corresponding to the Redcap UE is offset by N frequency domain positions with respect to the synchronization grid position of the SSB corresponding to the normal UE; and/or

The location of the time domain resource at the time of SSB transmission corresponding to the Redcap UE is different from the location of the time domain resource at the time of SSB transmission corresponding to the normal UE (e.g., two different SSBs may be transmitted on different half frames or different system frames or different time slots, respectively, based on protocol conventions).

In one possible implementation, N may be an integer.

It should be noted that, in one embodiment of the present disclosure, the above-mentioned location of the time domain resource corresponding to the SSB transmission of the Redcap UE may be determined based on a protocol. In another embodiment of the present disclosure, the location of the time domain resource at the time of SSB transmission corresponding to the Redcap UE may be based on a base station configuration, and in another embodiment of the present disclosure, the location of the time domain resource at the time of SSB transmission corresponding to the Redcap UE may be based on a base station indication.

And, in one embodiment of the present disclosure, N as described above may be determined based on a protocol convention (e.g., for an initial cell search, N may be determined based on a protocol convention). In another embodiment of the present disclosure, N as described above may be determined based on the base station indication (e.g., for RRM measurements, RLM measurements, beam management, etc., N may be determined based on the base station indication).

Still further, the above-described structure at the time of SSB transmission corresponding to the Redcap UE and SSB transmission corresponding to the normal UE is exemplified. Fig. 3b is a schematic structural diagram of SSB corresponding to a common UE with a subcarrier spacing of 30KHZ according to an embodiment of the present disclosure, and fig. 3c-3e are schematic structural diagrams of SSB corresponding to a Redcap UE with a subcarrier spacing of 30KHZ according to an embodiment of the present disclosure. Of course, 30KHz is used for illustration only.

As shown in fig. 3b, the structure of SSB corresponding to a general UE with a subcarrier spacing of 30KHZ mainly includes PSS, SSS, PBCH. Wherein, the time domain resource length of the SSB with the subcarrier spacing of 30KHZ corresponding to the common UE is as follows: the 4 symbols, the frequency domain resource length is: 20 RBs (Resource Block), in the frequency domain, PSS and SSS occupy 12 RBs (including guard interval), PBCH occupies 20 RBs, and total bandwidth of SSB corresponding to common UE with subcarrier interval of 30KHZ exceeds bandwidth range of Redcap UE due to overlong length of frequency domain resources occupied by PBCH in SSB corresponding to common UE with subcarrier interval of 30KHZ, so that SSB corresponding to common UE with subcarrier interval of 30KHZ cannot be received and decoded by Redcap UE.

And, as shown in comparison of fig. 3b and fig. 3c-3e, the frequency domain resource length of SSB corresponding to Redcap UE with subcarrier spacing of 30KHZ is 11 RBs, which is smaller than the frequency domain resource length of SSB corresponding to normal UE with subcarrier spacing of 30KHZ by 20RB, the time domain resource length of SSB corresponding to Redcap UE with subcarrier spacing of 30KHZ is 6 symbols, which is larger than the time domain resource length of SSB corresponding to normal UE with subcarrier spacing of 30KHZ by 4 symbols.

Further, it should be noted that, in one embodiment of the present disclosure, at least one SSB may be transmitted in the same timeslot, where transmission positions of different SSBs may be different, so that at least one SSB candidate position needs to be determined generally, where the SSB candidate position is a starting transmission position of different SSBs in the same timeslot. On this basis, since the length of the time domain resource of the SSB corresponding to the Redcap UE is greater than that of the SSB corresponding to the Redcap UE, when the SSB corresponding to the Redcap UE is transmitted, if the method of determining the SSB candidate position when the SSB corresponding to the normal UE is transmitted is still utilized, a phenomenon that the current SSB corresponding to the Redcap UE overlaps with the time domain resource of the SSB corresponding to the Redcap UE immediately after may occur, thereby affecting the transmission efficiency, and thus, it is generally required to improve the method of determining the original SSB candidate position (i.e., the method of determining the candidate position of the SSB corresponding to the normal UE).

Specifically, the method for determining the original SSB candidate position includes the following three methods, namely Case a, case B, case C, and specifically, one method can be selected from the three methods according to factors such as carrier frequency band and SCS to determine the SSB candidate position. Wherein, case A, case B, case C are respectively as follows:

for a field having an SS/PBCH block, it is necessary to determine the first symbol index of the candidate SS/PBCH block from the SCS of the SS/PBCH block, wherein the method of determining the first symbol index of the candidate SS/PBCH block from the SCS of the SS/PBCH block is as follows, wherein index 0 corresponds to the first symbol frame of the first slot of the half slots.

Case a: when the SCS subcarrier spacing is 15kHz, the index of the first symbol of the candidate SS/PBCH block is {2,8} +14.n.

Among other things, in one embodiment of the present disclosure, for unshared spectrum: for carrier frequencies less than or equal to 3GHz, n=0, 1; for carrier frequencies greater than 3GHz within FR1, n=0, 1,2,3.

Case B: when the SCS subcarrier spacing is 30kHz, the index of the first symbol of the candidate SS/PBCH block is {4,8,16,20} +28.n.

Wherein, in one embodiment of the present disclosure, n=0 for carrier frequencies less than or equal to 3 GHz; for carrier frequencies greater than 3GHz within FR1, n=0, 1.

Case C: the first symbol of the candidate SS/PBCH block has the index 2,8 +14 n with a SCS subcarrier spacing of 30 kHz.

Wherein in one embodiment of the present disclosure, the spectrum is not shared and is used for paired spectrum operation, n=0, 1 for carrier frequencies less than or equal to 3 GHz; for carrier frequencies greater than 3GHz within FR1, n=0, 1,2,3.

And, in one embodiment of the present disclosure, non-shared spectrum, and for unpaired spectrum operation, n=0, 1 for carrier frequencies less than 1.88 GHz; for carrier frequencies equal to or greater than 1.88GHz within FR1, n=0, 1,2,3.

It can be seen from the above that when the method for determining the candidate positions of the original SSBs is Case B, the initial transmission positions of the adjacent SSBs are separated by 4 symbols. Based on this, for the structure of SSB corresponding to normal UE with subcarrier spacing of 30KHZ, since the time domain resource length of SSB corresponding to normal UE is 4 symbols (refer to fig. 3 a), there is no time domain resource overlap between adjacent SSBs, but for the structure of SSB corresponding to Redcap UE with subcarrier spacing of 30KHZ, since the time domain resource length of SSB corresponding to Redcap UE is greater than the time domain resource length of SSB corresponding to normal UE by 6 symbols, at this time, the time domain resource length of SSB corresponding to Redcap UE is greater than the initial transmission position of adjacent SSB determined by Case B, so that adjacent SSB corresponding to Redcap UE will have time domain resource overlap. Therefore, an improvement of the Case B method is needed so that the SSB corresponding to the Redcap UE does not overlap time domain resources by using the improved Case B. In one embodiment of the present disclosure, the modified Case B may include at least one of:

Modified Case B-1 (using a candidate SSB position that can be determined for the structure of fig. 3 c): when the subcarrier spacing is 30kHz, the index of the first symbol of the candidate SS/PBCH block is {2,8, 16, 22} +28 x n.

Wherein, in one embodiment of the present disclosure, n=0, 1 for carrier frequencies greater than 3GHz within FR 1.

Modified Case B-2 (using a candidate SSB position that can be determined for the structure of fig. 3 e): when the subcarrier spacing is 30kHz, the index of the first symbol of the candidate SS/PBCH block is {3,8, 16, 22} +28×n.

Step 302, receiving SSB resources sent by a base station based on the determined parameters of the SSB resources.

Wherein, in one embodiment of the present disclosure, the method for the Redcap UE to receive SSB resources transmitted by the base station based on the determined parameters of the SSB resources may include at least one of the following:

first, performing SSB reception corresponding to a normal UE at a first subcarrier interval at a time-frequency domain position of the SSB corresponding to the normal UE, and receiving the SSB corresponding to a Redcap UE at the first subcarrier interval and/or a second subcarrier interval at the time-frequency domain position dedicated to transmission of resources of the SSB corresponding to the Redcap UE in response to not receiving the SSB corresponding to the normal UE;

Second, the SSB corresponding to the Redcap UE is received at a first subcarrier spacing and/or a second subcarrier spacing directly at the time-frequency domain location dedicated to transmitting the resources of the SSB corresponding to the Redcap UE.

For the first mode, if SSB reception is performed at a time-frequency domain location corresponding to the SSB of the normal UE, wherein in response to receipt of the PSS and SSS, but the PBCH is not successfully received, PBCH reception needs to be continued at a time-frequency domain location dedicated to transmission of the resources corresponding to the SSB of the Redcap UE. And, in one embodiment of the present disclosure, one possible way is to perform HARQ combining and decoding on the PBCH in the SSB corresponding to the normal UE and the PBCH in the SSB corresponding to the Redcap UE, where combining requires that the PBCH in the SSB corresponding to the Redcap UE carries the same information bits as the PBCH in the SSB corresponding to the normal UE, and then the UE may perform frame timing determination for the anchor point according to the time domain location of the SSB corresponding to the normal UE. Alternatively, in another embodiment of the present disclosure, HARQ combining is not performed, in which case the PBCH content corresponding to the Redcap UE may be the same as or different from the PBCH content corresponding to the normal UE. In one embodiment, if the frame timing is the same, the frame timing determination method is: the UE makes a frame timing determination for the anchor point according to the time domain position of the SSB corresponding to the normal UE. In another embodiment, the determination of the frame timing is made with the time domain location of the dedicated SSB corresponding to the Redcap UE as the anchor point if it is different.

And, it should be noted that, in one embodiment of the present disclosure, the Redcap UE receives the SSB corresponding to the Redcap UE, specifically using the first subcarrier spacing or the second subcarrier spacing or using the first subcarrier spacing and the second subcarrier spacing respectively, at a time domain location dedicated to transmitting the SSB corresponding to the Redcap UE, which may be determined according to a carrier frequency band or may be determined based on a configuration and/or an indication of a base station, or may be determined according to a protocol convention.

Specifically, in one embodiment of the present disclosure, for SSBs corresponding to the Redcap UE applied to the initial cell search, a subcarrier spacing of the SSBs corresponding to the Redcap UE may be determined according to a carrier frequency band. Specifically, for a carrier frequency band supporting only a first subcarrier spacing, the SSB corresponding to the Redcap UE may be received using the first subcarrier spacing, for a carrier frequency band supporting only a second subcarrier spacing, the SSB corresponding to the Redcap UE may be received using the second subcarrier spacing, and for a carrier frequency band supporting both the first subcarrier spacing and the second subcarrier spacing, the first subcarrier spacing and/or the second subcarrier spacing may be used to perform frequency sweep to receive the SSB corresponding to the Redcap UE.

And, in one embodiment of the present disclosure, for SSBs corresponding to the Redcap UE in SSB synchronization applied to RRM measurement, and/or RLM measurement, and/or SSB management, and/or after cell access, a subcarrier spacing used when receiving SSBs corresponding to the Redcap UE may be determined based on a configuration and/or an indication of a base station.

In another embodiment of the present disclosure, the SSB corresponding to the Redcap UE may be received by the UE at all times in any frequency band at a first subcarrier spacing based on a protocol convention at a time domain location dedicated to transmitting the resources of the SSB corresponding to the Redcap UE.

Fig. 4 is a flowchart of an information transmission method according to another embodiment of the present disclosure, which is applied to a Redcap UE, as shown in fig. 4, and the information transmission method may include the following steps:

step 401, determining a parameter for transmitting SSB resources of the Redcap UE, where the parameter for transmitting SSB resources of the Redcap UE includes a resource dedicated to transmitting SSB corresponding to the Redcap UE, and the resource dedicated to transmitting SSB corresponding to the Redcap UE is a resource of the first subcarrier spacing.

Step 402, receiving SSB resources sent by a base station based on the determined parameters of the SSB resources.

The detailed descriptions of the steps 401 to 402 may be described with reference to the above embodiments, and the embodiments of the disclosure are not repeated herein.

In summary, in the information transmission method provided in the embodiments of the present disclosure, the UE may receive the SSB according to the first subcarrier interval; and/or the UE may determine a new time-frequency domain resource and receive a PBCH transmitted by the base station at the new time-frequency domain resource. Wherein, the first subcarrier spacing satisfies: when the SSB uses the first subcarrier spacing, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE, that is, when the subcarrier spacing of the SSB is the first subcarrier spacing, the Redcap UE can successfully receive and decode the SSB. And the length of the frequency domain resource of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE, that is, the UE can always successfully receive the PBCH sent by the base station by the new time-frequency domain resource no matter what subcarrier interval corresponds to the SSB of the common UE. As can be seen, the information transmission method provided by the embodiment of the present disclosure may ensure that the UE can successfully receive the SSB of the first subcarrier interval, and/or the PBCH sent by the base station in the new time-frequency domain resource, so that the transmission stability is improved.

Step 502, receiving SSB resources sent by a base station based on the determined parameters of the SSB resources.

The detailed descriptions of the above steps 501-502 may be described with reference to the above embodiments, which are not described herein.

In summary, in the information transmission method provided in the embodiments of the present disclosure, the Redcap UE may receive the SSB according to the first subcarrier interval; and/or, the Redcap UE may receive, at the new time-frequency domain resource, the PBCH transmitted by the base station at the new time-frequency domain resource. Wherein, the first subcarrier spacing satisfies: when the SSB uses the first subcarrier spacing, the bandwidth of the SSB is less than or equal to the bandwidth range of the Redcap UE, that is, when the subcarrier spacing of the SSB is the first subcarrier spacing, the UE can successfully receive and decode the SSB. And the length of the frequency domain resource of the new time-frequency domain resource is less than or equal to the bandwidth range of the Redcap UE, that is, the UE can always successfully receive the PBCH sent by the base station by the new time-frequency domain resource no matter what subcarrier interval corresponds to the SSB of the common UE. As can be seen, the information transmission method provided by the embodiment of the present disclosure may ensure that the UE can successfully receive the SSB of the first subcarrier interval, and/or the PBCH sent by the base station in the new time-frequency domain resource, so that the transmission stability is improved.

Fig. 6 is a flowchart of an information transmission method according to another embodiment of the present disclosure, which is applied to a Redcap UE, and as shown in fig. 6, the information transmission method may include the following steps:

step 601, determining parameters for transmitting SSB resources of the Redcap UE, where the parameters for transmitting SSB resources of the synchronization signal block of the Redcap UE include parameters of a PBCH dedicated to transmitting SSB of the Redcap UE.

Among other things, in one embodiment of the disclosure, the above parameters of the PBCH dedicated to transmitting SSBs of the Redcap UE may include:

or (b)

And the time-frequency domain resource dedicated to transmitting the PBCH corresponding to the Redcap UE is smaller than or equal to the bandwidth range of the Redcap UE.

Wherein the detailed description about the above parts will be described in the following embodiments.

Step 602, receiving SSB resources sent by a base station based on the determined parameters of the SSB resources.

In one embodiment of the present disclosure, when it is determined in the above step 601 that the parameters of the PBCH dedicated to transmitting the SSB of the Redcap UE are different, the method of receiving the SSB resource transmitted by the base station in this step is also different, and this part will be described in detail in the following embodiments.

Fig. 7a is a flowchart of an information transmission method according to another embodiment of the present disclosure, which is applied to a Redcap UE, as shown in fig. 7a, and the information transmission method may include the following steps:

step 701a, determining a parameter of a synchronization signal block SSB resource for transmitting a Redcap UE, where the parameter of the synchronization signal block SSB resource for transmitting the Redcap UE includes at least two parts of time-frequency domain resources for transmitting a PBCH corresponding to the Redcap UE.

In one embodiment of the present disclosure, the frequency domain resource length of each part of the time-frequency domain resource 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 resource is less than the frequency domain resource length of the time-frequency domain resource corresponding to the normal UE for transmitting the PBCH.

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

the first part of resources are time-frequency domain resources corresponding to SSB of the common UE and are used for transmitting data which does not exceed the bandwidth range of the Redcap UE in PBCH of SSB of the common UE;

The second portion of resources may be different from the above-mentioned time-frequency domain resources corresponding to the SSB of the normal UE, and may be used to transmit data exceeding the bandwidth range of the Redcap UE in the PBCH corresponding to the SSB of the normal UE.

Step 702a, receiving PSS, SSS in SSB corresponding to the normal UE at a synchronization grid position corresponding to the SSB of the normal UE and data not exceeding a bandwidth range of the Redcap UE in PBCH corresponding to the SSB of the normal UE at a first partial resource and receiving data exceeding the bandwidth range of the Redcap UE in PBCH corresponding to the SSB of the normal UE at a second partial resource in response to the subcarrier spacing of the SSB corresponding to the normal UE being a second subcarrier spacing, wherein the second partial resource is a first symbol before and/or after the time-frequency domain resource corresponding to the SSB of the normal UE.

Wherein, in one embodiment of the present disclosure, the frequency domain resource length of the first symbol may be less than or equal to the bandwidth range of the Redcap UE.

Further, to illustrate the receiving manner in the step 702a, fig. 7b-7e are schematic structural diagrams of SSB corresponding to Redcap UE sent by the step 702a according to the embodiments of the present disclosure. As shown in fig. 7b-7e, PSS and SSS in SSB corresponding to the Redcap UE are still transmitted at the synchronization grid position corresponding to SSB of the normal UE, and data in PBCH corresponding to SSB of the Redcap UE which does not exceed the bandwidth range of the Redcap UE (i.e., PBCH data not filled with hatching in the figure) is transmitted on the first part of resources (synchronization grid position corresponding to when data in SSB of the normal UE which does not exceed the bandwidth range of the Redcap UE is transmitted). And, data exceeding the bandwidth range of the Redcap UE in the PBCH corresponding to the SSB of the normal UE (i.e., PBCH data filled with hatching in the figure) is transmitted before and/or after the time-frequency domain resources corresponding to the SSB of the normal UE.

As can be seen from fig. 7b, the data exceeding the bandwidth range of the Redcap UE in the PBCH corresponding to the SSB of the normal UE is transmitted by the first symbol after the time-frequency domain resource corresponding to the SSB of the normal UE. Referring to fig. 7c, it can be seen that data exceeding the bandwidth range of the Redcap UE in the PBCH corresponding to the SSB of the normal UE is transmitted in the first symbol before the time-frequency domain resource corresponding to the SSB of the normal UE. Referring to fig. 7d, it can be seen that data exceeding the bandwidth range of the Redcap UE in the PBCH corresponding to the SSB of the normal UE is transmitted in the first symbol before and after the time-frequency domain resources corresponding to the SSB of the normal UE.

Fig. 8a is a flowchart of an information transmission method according to another embodiment of the present disclosure, which is applied to a Redcap UE, as shown in fig. 8a, and the information transmission method may include the following steps:

step 801a, determining a parameter of a synchronization signal block SSB resource for transmitting a Redcap UE, where the parameter of the synchronization signal block SSB resource for transmitting the Redcap UE includes at least two parts of time-frequency domain resources for transmitting a PBCH corresponding to the Redcap UE.

Step 802a, receiving PSS, SSS in SSB corresponding to the normal UE in a synchronization grid position corresponding to the SSB of the normal UE and data which does not exceed the bandwidth range of the Redcap UE in PBCH corresponding to the SSB of the normal UE in a first part of resources based on a radio frequency retuning technique, and receiving data which exceeds the bandwidth range of the Redcap UE in PBCH corresponding to the SSB of the normal UE in a second part of resources based on a radio frequency retuning technique, wherein the second part of resources are different from the first part of resources in frequency domain position.

Fig. 8b and 8c are schematic structural diagrams of SSB sent by step 802a and corresponding to Redcap UE, which are provided in the embodiments of the present disclosure, by way of example of the receiving manner in step 802 a. As shown in fig. 8b and 8c, PSS and SSS in SSB corresponding to the Redcap UE are still transmitted at the synchronization grid position corresponding to SSB of the normal UE, and data in PBCH corresponding to SSB of the Redcap UE which does not exceed the bandwidth range of the Redcap UE (i.e., PBCH data not filled with hatching in the figure) is transmitted on the first part of resources (synchronization grid position corresponding to when data in SSB of the normal UE which does not exceed the bandwidth range of the Redcap UE is transmitted). And, data exceeding the bandwidth range of the Redcap UE in the PBCH corresponding to the SSB of the normal UE (i.e., PBCH data filled with hatching in the figure) is received at the second portion of resources based on the radio frequency retune technique.

The manner in which the second portion of resources are frequency division multiplexed with the first portion of resources may be as shown in fig. 8b or fig. 8c, for example.

And, in one embodiment of the present disclosure, when receiving data exceeding the bandwidth range of the Redcap UE in the PBCH corresponding to the SSB of the normal UE through the radio frequency retuning technique in the second part of resources, the UE needs to determine the time domain interval and the frequency domain interval of the second part of resources compared to the first part of resources first to ensure successful reception of the data exceeding the bandwidth range of the Redcap UE in the PBCH corresponding to the SSB of the normal UE.

Among other things, in one embodiment of the present disclosure, a method of determining a time interval and a frequency domain interval of frequency division multiplexing may include:

determining a time domain interval and a frequency domain interval in frequency division multiplexing based on a protocol convention; and/or

Determining a time domain interval and a frequency domain interval in frequency division multiplexing based on a base station configuration; and/or

A time domain interval and a frequency domain interval in frequency division multiplexing are determined based on the base station indication.

Further, it should be noted that in one embodiment of the present disclosure, it takes a certain time for the Redcap UE to perform radio frequency retune, that is, to adjust the center frequency point of the radio frequency bandwidth from the center frequency point of the first part of resources to the center frequency point of the second part of resources, based on which a guard time interval is required for transmission between PSS, SSS, and data in PBCH in SSB corresponding to the normal UE, which do not exceed the bandwidth range of the Redcap UE, and data in PBCH in the PBCH corresponding to the normal UE, which exceeds the bandwidth range of the Redcap UE (e.g., guard symbol shown in fig. 8b and 8 c). Then, after the Redcap UE receives the PSS, SSS, and data in the PBCH that do not exceed the bandwidth range of the Redcap UE in the SSB corresponding to the normal UE, there may be enough time to adjust the center frequency point of the radio frequency bandwidth from the center frequency point of the first partial resource to the center frequency point of the second partial resource so that subsequent reception of data in the PBCH that exceeds the bandwidth range of the Redcap UE in the SSB corresponding to the normal UE may be completed based on the radio frequency re-tuning.

In addition, it should be further noted that, when the second partial resource is frequency division multiplexed with the first partial resource, in one embodiment of the present disclosure, the subcarrier spacing of the first partial resource may be the same as the subcarrier spacing of the second partial resource. In another embodiment of the present disclosure, the subcarrier spacing of the first partial resources may be different from the subcarrier spacing of the second partial resources.

Fig. 9a is a flowchart of an information transmission method according to another embodiment of the present disclosure, which is applied to a Redcap UE, as shown in fig. 9a, and the information transmission method may include the following steps:

step 901a, determining a parameter of a synchronization signal block SSB resource for transmitting the Redcap UE, where the parameter of the synchronization signal block SSB resource for transmitting the Redcap UE includes at least two parts of time-frequency domain resources for transmitting the PBCH corresponding to the Redcap UE.

Step 902a, in response to the subcarrier spacing of the SSB corresponding to the ordinary UE being the second subcarrier spacing, receiving PSS, SSS in the SSB corresponding to the ordinary UE at the synchronization grid location corresponding to the SSB of the ordinary UE, and receiving data in the PBCH corresponding to the SSB of the ordinary UE that does not exceed the bandwidth range of the Redcap UE at the first portion of resources, and receiving a first portion of the data in the PBCH corresponding to the SSB of the ordinary UE that exceeds the bandwidth range of the Redcap UE at a portion of the second portion of resources, receiving a second portion of the data in the PBCH corresponding to the SSB of the ordinary UE that exceeds the bandwidth range of the Redcap UE at another portion of the second portion of resources based on a radio frequency retuning technique.

In one embodiment of the present disclosure, a part of the second partial resources may be first symbols before and/or after the time-frequency domain resources corresponding to the SSB of the normal UE, and another part of the second partial resources may be frequency-division multiplexed with the first partial resources.

Fig. 10a is a flowchart of an information transmission method according to another embodiment of the present disclosure, which is applied to a Redcap UE, as shown in fig. 10a, and the information transmission method may include the following steps:

step 1001a, determining parameters for transmitting synchronization signal block SSB resources of a Redcap UE, the parameters for transmitting synchronization signal block SSB resources of the Redcap UE including time-frequency domain resources dedicated to transmitting PBCH corresponding to the Redcap UE.

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

Step 1002a, in response to the subcarrier spacing of the SSB corresponding to the normal UE being the second subcarrier spacing, receiving data within the bandwidth range of the Redcap UE in the PSS, SSS, and PBCH in the SSB corresponding to the normal UE at the synchronization grid location corresponding to the SSB of the normal UE, and receiving all PBCH information in the SSB corresponding to the normal UE on time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE.

In one embodiment of the present disclosure, the PBCH that is responsive to the synchronization grid location of the SSB of the normal UE carries the same information bits as the PBCH that is carried on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, and the PBCH data that the Redcap UE receives at the synchronization grid location of the original SSB is combined (e.g., may be HARQ (Hybrid Automatic Repeatrequest, hybrid automatic repeat request) combined) with the PBCH data that the Redcap UE receives on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, and downlink synchronization and frame timing are performed for the anchor point based on the symbol location of the PSS and/or SSS.

In another embodiment of the present disclosure, HARQ combining is not performed in response to the PBCH of the synchronization grid location of the original SSB carrying information bits different from the PBCH carried on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, and downlink synchronization and frame timing are performed for the anchor point based on the time-domain location dedicated to transmitting the PBCH corresponding to the Redcap UE.

It should be noted that, in one embodiment of the present disclosure, if the UE first receives data in the PBCH within the bandwidth range of the Redcap UE at the synchronization grid location corresponding to the SSB of the normal UE, the UE may attempt to decode the received PBCH data, and if the decoding is successful, the UE may not receive data on the time-frequency domain resource dedicated to transmitting the PBCH corresponding to the Redcap UE.

In one embodiment of the present disclosure, after the UE receives data in the PBCH within the bandwidth range of the Redcap UE in the synchronization grid position corresponding to the SSB of the normal UE, the UE may not decode the received PBCH data, but may combine the PBCH data received by the Redcap UE in the synchronization grid position of the original SSB with the PBCH data received by the Redcap UE in the time-frequency domain resource dedicated to the transmission of the PBCH corresponding to the Redcap UE after receiving the data on the time-frequency domain resource dedicated to the transmission of the PBCH corresponding to the Redcap UE.

In one embodiment of the present disclosure, if the UE first receives all PBCH information in the SSB corresponding to the normal UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, it may attempt to decode the received PBCH data, and if the decoding is successful, it may not receive data in the PBCH within the bandwidth range of the Redcap UE at the synchronization grid position corresponding to the SSB of the normal UE.

In one embodiment of the present disclosure, after the UE receives all PBCH information in the SSB corresponding to the normal UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, the UE may not decode the received PBCH data, but may combine PBCH data received by the Redcap UE at the synchronization grid position of the original SSB with PBCH data received by the Redcap UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE after receiving data in the bandwidth range of the Redcap UE in the PBCH corresponding to the SSB synchronization grid position of the normal UE.

Further, it should be noted that, in an embodiment of the present disclosure, the above-mentioned time-frequency domain resource dedicated to transmitting the PBCH corresponding to the Redcap UE may be the first symbol before and/or after the time-frequency domain resource corresponding to the SSB of the normal UE. The above-described method of receiving all PBCH information in SSBs corresponding to general UEs on time-frequency domain resources dedicated to transmitting PBCH corresponding to the Redcap UE may include: all PBCH information in the SSB corresponding to the normal UE is received on the first symbol.

As shown in fig. 10b and fig. 10c, all New PBCH in the drawing is all PBCH information in the SSB corresponding to the normal UE, where in fig. 10b, all PBCH information in the SSB corresponding to the normal UE is transmitted on a first symbol before the time-frequency domain resource of the SSB corresponding to the normal UE. In fig. 10c, all PBCH information in the SSB corresponding to the normal UE is transmitted on the first symbol after the time-frequency domain resource of the SSB corresponding to the normal UE

In another embodiment of the present disclosure, the above-described receiving all PBCH information in the SSB corresponding to the normal UE on the time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE may include:

all PBCH information in the SSB corresponding to the normal UE is received on time-frequency domain resources dedicated to transmitting the PBCH corresponding to the Redcap UE, which are frequency-division multiplexed with the time-frequency domain resources corresponding to the SSB of the normal UE, based on the radio frequency retuning technique.
