Description

Information processing method and related device

[0001] The present application claims priority from the Chinese patent application No. 202411392550.2 filed on September 30, 2024, and entitled "Information transmission method and related device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to an information transmission method and related device. BACKGROUND

[0003] Subband full duplex (SBFD) is a new duplexing mode. By dividing non-overlapping uplink / downlink subbands in a time division duplexing (TDD) single carrier and performing data transmission and reception on the subbands respectively, full duplex can be achieved at the base station side. For example, TDD can perform transmission and reception through different time slots on the same spectrum, and the uplink and downlink transmission cannot be performed simultaneously, and a switching interval is required between the uplink and downlink. SBFD divides the same spectrum into uplink subbands and downlink subbands, and performs transmission and reception on different subbands simultaneously.

[0004] Generally, one carrier component (CC) can be divided into multiple subbands (SBs) in the frequency domain range on a downlink (DL) symbol or a flexible (F) symbol. The multiple SBs can include one uplink (UL) subband and at least one DL subband. For example, one or two DL subbands. When a symbol (DL symbol or F symbol) includes a DL subband and a UL subband in the frequency domain at the same time, the symbol can be referred to as an SBFD symbol.

[0005] Currently, random access (RA) under the SBFD symbol is not configured, which affects the random access under the SBFD symbol. SUMMARY

[0006] The present application provides an information processing method and related device to configure time domain resources for the RO of the SBFD symbol, and to implement random access on the SBFD symbol.

[0007] To achieve the above purpose, the present application provides the following technical solutions:

[0008] In a first aspect, the present application provides an information processing method, which comprises: obtaining a first time domain resource position corresponding to a random access occasion (RO), obtaining an offset parameter by using a target time domain resource position and a reference time domain resource position in a frame, the target time domain resource position being a time domain resource position corresponding to a non-SBFD symbol in the frame, and the reference time domain resource position being a time domain resource position corresponding to an SBFD symbol in the frame, adjusting the first time domain resource position by using the offset parameter to obtain a second time domain resource position, and the second time domain resource being suitable for random access on the SBFD symbol. That is, the present application adjusts the RO time domain resource position configured in the existing configuration table by using the time domain resource position corresponding to the SBFD symbol in the frame, so that the time domain resource position corresponding to the adjusted RO is suitable for random access on the SBFD symbol.

[0009] The target time domain resource position and the reference time domain resource position can be divided into the following different cases:

[0010] In a first application scenario, the target time domain resource position is a time domain resource position corresponding to a last non-SBFD symbol in the frame, and the reference time domain resource position is a time domain resource position corresponding to an SBFD symbol included in a last symbol in the frame, or the reference time domain resource position is a time domain resource position corresponding to an SBFD symbol included in a last symbol in the frame. That is, the reference time domain resource position is a last SBFD subframe (or SBFD slot) in the frame, and the symbols included in the SBFD subframe (or SBFD slot) are all SBFD symbols, or the reference time domain resource position is a subframe (or slot) in which a first SBFD symbol is located, and the symbols included in the subframe (or slot) can include SBFD symbols and other symbols, or can only include SBFD symbols.

[0011] In a second application scenario, the target time domain resource position is a time domain resource position corresponding to a first non-SBFD symbol in the frame, and the reference time domain resource position is a time domain resource position corresponding to an SBFD symbol included in a first symbol in the frame, or the reference time domain resource position is a time domain resource position corresponding to an SBFD symbol included in a first symbol in the frame. That is, the reference time domain resource position is a first SBFD subframe (or SBFD slot) in the frame, and the symbols included in the SBFD subframe (or SBFD slot) are all SBFD symbols, or the reference time domain resource position is a subframe (or slot) in which a first SBFD symbol is located, and the symbols included in the subframe (or slot) can include SBFD symbols and other symbols, or can only include SBFD symbols.

[0012] The offset parameter can be obtained according to the following manner:

[0013] In an implementation manner, the interval between the target time domain resource position and the reference time domain resource position in any frame is taken as the offset parameter.

[0014] An implementation is to take the interval between the target time domain resource location and the reference time domain resource location in an odd frame as the offset parameter.

[0015] An implementation is to take the interval between the target time domain resource location and the reference time domain resource location in an even frame as the offset parameter.

[0016] For any of the above implementations, for the obtained offset parameter, the first time domain resource location in all frames is adjusted by using the offset parameter to obtain a second time domain resource location.

[0017] In addition, before performing the above three implementations, the size relationship between the frame period and the association period can be determined first, and different implementations are used to obtain the offset parameter for different relationships. The association period refers to a period in which a frame and an SBFD mode appear simultaneously. For example, the association period can be the least common multiple of the frame period and the SBFD mode period.

[0018] Specifically, if the frame period and the association period are the same, the interval between the target time domain resource location and the reference time domain resource location in any frame is taken as the offset parameter, and the first time domain resource location in all frames is adjusted by using the offset parameter to obtain a second time domain resource location.

[0019] If the frame period and the association period are not the same, the interval between the target time domain resource location and the reference time domain resource location in an odd frame is taken as the offset parameter, and / or the interval between the target time domain resource location and the reference time domain resource location in an even frame is taken as the offset parameter.

[0020] In this implementation, the first time domain resource location located in all frames can be adjusted by using a first offset parameter to obtain a second time domain resource location. The first offset parameter is determined based on the interval between the target time domain resource location and the reference time domain resource location in an odd frame. Or the first time domain resource location located in all frames can be adjusted by using a second offset parameter to obtain a second time domain resource location. The second offset parameter is determined based on the interval between the target time domain resource location and the reference time domain resource location in an even frame. Or, the first time domain resource location located in an odd frame can be adjusted by using the first offset parameter to obtain a second time domain resource location, and the first time domain resource location located in an even frame can be adjusted by using the second offset parameter to obtain a second time domain resource location.

[0021] In some embodiments, if the application scenario is the first application scenario, adjusting the first time domain resource position according to the offset parameter to obtain the second time domain resource position comprises: subtracting the offset parameter from the first time domain resource position, taking the first parameter value as a modulus, and taking the time domain resource position indicated by the remainder as the second time domain resource position. The first parameter value is the total number of time domain resources included in a frame.

[0022] If the application scenario is the second application scenario, adjusting the first time domain resource position according to the offset parameter to obtain the second time domain resource position comprises: updating the first time domain resource position based on the first parameter value to obtain an updated first time domain resource position, adding the offset parameter to the updated first time domain resource position, taking the first parameter value as a modulus, and taking the time domain resource position indicated by the remainder as the second time domain resource position. The first parameter value is the total number of time domain resources included in a frame.

[0023] The updating of the first time domain resource position based on the first parameter value to obtain the updated first time domain resource position comprises: subtracting a second parameter value from the first parameter value and the first time domain resource position to obtain the updated first time domain resource position. The second parameter value is determined according to actual application conditions. For example, if the subframe sequence number in a frame starts from 0, the second parameter value is 1; if the subframe sequence number in a frame starts from 1, the second parameter value is 0.

[0024] In a second aspect, the present application provides a communication device comprising a processor configured to execute computer programs or computer instructions in a memory to perform the method provided in any one of the embodiments of the first aspect.

[0025] In a third aspect, the present application provides a computer storage medium configured to store a computer program, which, when executed, is configured to implement the method provided in any one of the embodiments of the first aspect.

[0026] In a fourth aspect, the present application provides a computer program product comprising instructions which, when executed on at least one computing device, cause the at least one computing device to implement the method provided in any one of the embodiments of the first aspect.

[0035] In the present specification, the phrase “one embodiment” or “some embodiments” etc. means that a specific feature, structure or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Therefore, the phrases “in one embodiment”, “in some embodiments”, “in other some embodiments”, “in yet some embodiments” etc. appearing in different places in the present specification are not necessarily all referring to the same embodiment, but mean “one or more but not all embodiments”, unless otherwise specifically emphasized.

[0037] Random access (RA) refers to that a terminal device initiates a random access process on a random access channel (RACH), requests access to a base station through the process, receives a response of the base station and allocates an access channel. Wherein, the RACH configuration indicates the time domain resource corresponding to the RO by row indexing through a predefined configuration table, and the configuration indicates a plurality of subframe numbers or time slot numbers in a frame where the RO is located.

[0038] At present, the random access resource configured by the existing RACH configuration table is mainly applicable to random access on the UL symbol. Since the UL symbol and the SBFD symbol are located at different positions in a frame, for example, the SBFD symbol is located in the front part of the UL symbol, the existing RACH configuration table cannot be applied to random access on the SBFD symbol.

[0039] Based on this, the present application provides an information processing method, which adjusts the time domain resource position configured by the existing RO, obtains the time domain resource position corresponding to the adjusted RO, and is better applicable to random access on the SBFD symbol.

[0040] The communication system to which the present application is applicable can be a fifth generation (5G) communication system, can also be a LTE and 5G hybrid architecture, or a 5G new radio (5G NR) system, and a new communication system to be appeared in future communication development, etc. Wherein, the communication system includes at least two devices, and different devices can send signals to each other to realize data interaction. Exemplarily, the devices included in the communication system can be, for example, a software defined radio (SDR) terminal and a network element, which can be a base station, etc. Hereinafter, the communication system including a software radio terminal and a network element will be exemplarily described.

[0041] An example of the communication system is shown in FIG. 1, which includes a network element 1 and an SDR terminal 2.

[0042] In the embodiments provided in the present application, the network element 1 can be any device located at the network side and having wireless transceiving functions, including but not limited to: a base station (gNodeB or gNB) or a transmission receiving point (TRP) in new radio (NR), etc. The network element 1 can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. The network element 1 can include one or more co-sited or non-co-sited transmission reception points (TRPs). The network element 1 can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The network element 1 can communicate with the SDR terminal 2, or communicate with the SDR terminal 2 through a relay station.

[0043] The SDR terminal 2 can communicate with multiple network elements of different technologies, for example, the SDR terminal 2 can communicate with a network element supporting an LTE network, can also communicate with a network element supporting a 5G network, and can also perform dual connectivity with a network element supporting an LTE network and a network element supporting a 5G network.

[0044] Among them, the SDR terminal 2 refers to a terminal supporting a software-defined wireless communication protocol. In general, the frequency band, air interface protocol and functions of the SDR terminal 2 can be upgraded through software download and update, without the need to completely replace the hardware, which makes the SDR terminal 2 have higher flexibility and upgradability, so as to adapt to various communication environments and needs.

[0045] In the embodiments provided in the present application, the SDR terminal 2 can be various forms, for example, a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a vehicle-mounted terminal device, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The SDR terminal 2 can be a fixed terminal or a mobile terminal.

[0046] To facilitate understanding of the technical solutions of the present application, specific embodiments will be described below.

[0047] Referring to FIG. 2, which is a flow chart of an information processing method provided in an embodiment of the present application, as shown in FIG. 2, the method comprises the following steps:

[0048] S201: Obtain a first time domain resource position corresponding to the RO.

[0049] In the present embodiment, the first time domain resource position configured for the RO can be obtained from a pre-defined RACH configuration table. Specifically, if the RACH configuration table is a TDD FR1 configuration table (configuration table A), the first time domain resource position is a number of subframes; if the RACH configuration table is a TDD FR2 configuration table (configuration table B), the first time domain resource position is a number of slots.

[0050] S202: Obtain an offset parameter by using a target time domain resource position and a reference time domain resource position in a frame.

[0051] The target time domain resource position and the reference time domain resource position are located in the same frame, the target time domain resource position refers to a time domain resource position corresponding to a non-SBFD symbol in a frame, and the reference time domain resource position refers to a time domain resource position corresponding to an SBFD symbol in the frame. Specifically, the target time domain resource position refers to the relative position of the time domain resource position corresponding to the non-SBFD symbol in the frame, and the reference time domain resource position refers to the relative position of the time domain resource position corresponding to the SBFD symbol in the frame, and the two relative positions are the same.

[0052] In some application scenarios, the target time domain resource location is the time domain resource location corresponding to the last non-SBFD symbol in a frame, and the reference time domain resource location is the time domain resource location corresponding to the last symbol included in the frame that is an SBFD symbol. The non-SBFD symbol includes a DL symbol and an UL symbol. For example, as shown in FIG. 3a, X represents an SBFD symbol, D represents a DL symbol, and U represents an UL symbol. One frame includes 10 subframes, the target time domain resource location is the last U subframe, and the reference time domain resource location is the last SBFD subframe.

[0053] Alternatively, the reference time domain resource location is the time domain resource location corresponding to the last SBFD symbol in a frame, that is, the symbol included in the time domain resource location includes an SBFD symbol and other symbols (for example, an UL symbol), or the symbol included in the time domain resource location is an SBFD symbol. As shown in FIG. 3b, 10 subframes are included, which are subframe 0 to subframe 9. The subframe 3 includes an SBFD symbol and a U symbol at the same time. Therefore, the reference time domain resource location is the subframe number 3 corresponding to the subframe in which the last SBFD symbol is located.

[0054] That is, the target time domain resource location is the last subframe (or the last time slot) in a frame, and the reference time domain resource location is the last SBFD subframe (or the last SBFD time slot) in the frame or the subframe (or the time slot) in which the last SBFD symbol is located. In the scenario shown in FIG. 3b, if the reference signal resource location is the last SBFD subframe in a frame, the reference signal resource location is subframe 2; if the reference signal resource location is the subframe in which the last SBFD symbol is located, the reference signal resource location is subframe 3.

[0055] In some application scenarios, the target time domain resource location is the time domain resource location corresponding to the first non-SBFD symbol in a frame, and the reference time domain resource location is the time domain resource location corresponding to the first symbol included in the frame that is an SBFD symbol. For example, as shown in FIG. 4a, the target time domain resource location is the subframe number corresponding to the first D subframe, and the reference time domain resource location is the subframe number corresponding to the first SBFD subframe. Alternatively, the reference time domain resource location is the time domain resource location corresponding to the first SBFD symbol in a frame. The symbol included in the time domain resource location includes an SBFD symbol and other symbols (for example, a D symbol), or the symbol included in the time domain resource location can be an SBFD symbol. As shown in FIG. 4b, the subframe 1 includes an SBFD symbol and a D symbol, and the reference time domain resource location is the subframe 1.

[0056] That is, the target time domain resource position is the first subframe (or the first time slot) in a frame, and the reference time domain resource position is the first SBFD subframe (or the first SBFD time slot) or the subframe (or the time slot) in which the first SBFD symbol is located in the frame. In the scenario shown in FIG. 4b, if the reference signal resource position is the first SBFD subframe in the frame, the reference signal resource position is subframe 2; if the reference signal resource position is the subframe in which the first SBFD symbol is located, the reference signal resource position is subframe 1.

[0057] The offset parameter corresponding to the target time domain resource position and the reference time domain resource position can be calculated in the following manner:

[0058] In a first implementation, the interval between the target time domain resource position and the reference time domain resource position in any frame is directly taken as the offset parameter. In this implementation, the target time domain resource position and the reference time domain resource position in any frame are obtained, and the offset parameter is determined using the target time domain resource position and the reference time domain resource position.

[0059] In a second implementation, the interval between the target time domain resource position and the reference time domain resource position in an odd frame is taken as the offset parameter. In this implementation, the target time domain resource position and the reference time domain resource position in an odd frame are obtained, and the offset parameter is determined using the target time domain resource position and the reference time domain resource position.

[0060] In a third implementation, the interval between the target time domain resource position and the reference time domain resource position in an even frame is taken as the offset parameter. In this implementation, the target time domain resource position and the reference time domain resource position in an even frame are obtained, and the offset parameter is determined using the target time domain resource position and the reference time domain resource position.

[0061] Specifically, when determining the offset parameter, the relationship between the frame period and the associated period is first determined, and then the different implementations described above are adopted according to the relationship between the two. For example, if the frame period and the associated period are the same, the first implementation is adopted to determine the offset parameter; if the frame period and the associated period are different, the second implementation and / or the third implementation can be adopted to determine the offset parameter. The associated period refers to a period in which a frame and an SBFD mode can simultaneously appear repeatedly.

[0062] The associated period is determined based on the frame period and the SBFD mode period. Specifically, the least common multiple of the frame period and the SBFD mode period can be determined as the associated period.

[0063] The SBFD mode period is related to the TDD time slot period. Specifically, if a single TDD time slot mode is configured, the SBFD mode period is the same as the TDD time slot period; if a double TDD time slot mode is configured, the SBFD mode period is equal to the sum of two TDD time slot periods. For example, the TDD time slot period is P, and the SBFD mode period is Ps. In the single TDD time slot mode, Ps=P. If a double TDD time slot mode is configured, the second TDD time slot period is P2. In the double TDD time slot mode, Ps=P+P2.

[0064] S203: Adjusting the first time domain resource position according to the offset parameter to obtain a second time domain resource position.

[0065] The second time domain resource position is applicable to random access on the SBFD symbol.

[0066] Specifically, for the different ways of obtaining the offset parameter described above, the embodiment includes the following steps in adjusting the first time domain resource position according to the offset parameter to obtain a second time domain resource position.

[0067] In one case, no matter how the offset parameter is obtained based on the above three implementation manners, the first time domain resource position in all frames is adjusted by using the offset parameter to obtain a second time domain resource position.

[0068] In another case, when the frame period is different from the association period, the following steps can be included:

[0069] The first offset parameter is obtained based on the second implementation manner, and the first time domain resource position in all frames is adjusted by using the first offset parameter to obtain a second time domain resource position.

[0070] Alternatively, the second offset parameter is obtained based on the third implementation manner, and the first time domain resource position in all frames is adjusted by using the second offset parameter to obtain a second time domain resource position.

[0071] Alternatively, the first offset parameter is used to adjust the first time domain resource position in the odd frame to obtain a second time domain resource position; and the second offset parameter is obtained based on the third implementation manner, and the first time domain resource position in the even frame is adjusted by using the second offset parameter to obtain a second time domain resource position.

[0072] The first time domain resource is adjusted by using the offset parameter to obtain a second time domain resource position. Specifically, an intermediate parameter value can be obtained based on the first time domain resource position and the offset parameter, the intermediate parameter value is taken modulo with respect to a first parameter value, and a time domain resource position indicated by the remainder is taken as the second time domain resource position. The first parameter value is a total number of time domain resources included in a frame, for example, the first parameter value N is a total number of subframes or slots included in a frame.

[0073] For different application scenarios, the manner of obtaining the intermediate parameter value can include:

[0074] In an implementation, if the target time domain resource position is a time domain resource position corresponding to a last non-SBFD symbol in a frame, the first time domain resource position is subtracted by the offset parameter to obtain the intermediate parameter value. That is, a difference between the first time domain resource position and the offset parameter is taken as the intermediate parameter value.

[0075] In an implementation, if the target time domain resource position is a time domain resource position corresponding to a first non-SBFD symbol in a frame, the first time domain resource position is updated based on the first parameter value to obtain an updated first time domain resource position, and then the updated first time domain resource position is added to the offset parameter to obtain the intermediate parameter value. That is, a sum of the updated first time domain resource position and the offset parameter is taken as the intermediate parameter value.

[0076] In this implementation, the first time domain resource position is updated based on the first parameter value to obtain an updated first time domain resource position, including subtracting a second parameter value from the first parameter value and the first time domain resource position to obtain the updated first time domain resource position. That is, the first time domain resource position is mirror processed. The second parameter value can be determined according to actual conditions. The second parameter value can be determined according to actual application conditions. If the sequence number of the time domain resource position in a frame starts from 0, the second parameter value is 1. If the sequence number of the time domain resource position in a frame starts from 1, the second parameter value is 0.

[0077] For example, the first time domain resource position corresponding to an RO in a TDD RACH configuration table is a subframe number ρ, and the updated first time domain resource position ρ1=N-1-ρ, where N is a total number of subframes / slots included in a frame, and the second parameter value is 1.

[0078] To facilitate understanding of the specific implementation of the present application, the following will be described with reference to the accompanying drawings.

[0079] The frame period is P0, the TDD slot period is P, the SBFD mode period is Ps, and in the single TDD slot mode, Ps=P; if the double TDD slot mode is configured, and the second TDD slot mode period is P2, then in the double TDD slot mode, Ps=P+P2. Wherein, the association period of a frame and the SBFD mode is Pa, and then Pa=[P0, Ps], that is, the least common multiple of P0 and Ps.

[0080] (I) Reverse cyclic shift - shifting from right to left

[0081] When Pa=P0, the offset parameter Δ is equal to the subframe (or slot) interval between the last subframe (or slot) α and the adjustment reference point β in the frame period P0. Specifically, each RO subframe (or slot) number ρ in the adjustment table A or table B is (ρ-Δ)modN, where N is the total number of subframes (slots) contained in a frame.

[0082] When Pa≠P0, the determination of the offset parameter Δ has three options:

[0083] The offset parameter Δ is equal to the subframe (or slot) interval between the last subframe (or slot) α and the adjustment reference point β in the odd frame period P0. Specifically, each RO subframe (or slot) number ρ in the adjustment table A or table B is (ρ-Δ)modN;

[0084] The offset parameter Δ is equal to the subframe (or slot) interval between the last subframe (or slot) α and the adjustment reference point β in the even frame period P0. Specifically, each RO subframe (or slot) number ρ in the adjustment table A or table B is (ρ-Δ)modN;

[0085] The offset parameters Δ1 and Δ2 are respectively equal to the subframe (or slot) interval between the last subframe (or slot) α and the adjustment reference point β in the odd and even frame periods P0. Specifically, for the odd frame, each RO subframe (or slot) number ρ in the adjustment table A / table B is (ρ-Δ1)modN; for the even frame, each RO subframe (or slot) number ρ in the adjustment table A or table B is (ρ-Δ2)modN.

[0086] Wherein, no matter which of the above cases, β and α are in the same frame period.

[0087] In some embodiments, when the adjustment reference point β is the last SBFD subframe (or slot) in the system frame period P0 (all symbols in the subframe or slot are SBFD symbols), the specific implementation is shown in FIGS. 5a-5e.

[0088] For example, as shown in FIG. 5a, the frame period P0=10 ms, the application frequency band is FR1, the reference subcarrier spacing (SCS) is 15 kHz (thus N=10), the single TDD slot mode period is P=Ps=5 ms, in the 5 subframes contained in the period, the first subframe is a D subframe, the next two subframes are SBFD subframes (X in the figure), and the last two subframes are U subframes. Since the association period Pa=10 ms=P0, according to the calculation rule of the offset parameter under Pa=P0, a=9th subframe and β=7th subframe, then Δ=2. For the RACH configuration in which the subframe numbers of RO in a frame are 4 and 9, after adjusting the subframe numbers ρ∈{4, 9} to (ρ-2)mod10, the new subframe numbers of RO are (4-2)mod10=2 and (9-2)mod10=7.

[0089] For example, as shown in FIG. 5b, which is different from FIG. 5a in that the single TDD slot mode period is P=Ps=10 ms, in the 10 subframes contained in the period, the first subframe is a D subframe, the next three subframes are SBFD subframes, and the last six subframes are U subframes. The association period Pa=10 ms=P0, thus a=9th subframe and β=3rd subframe, and the offset parameter Δ=6. For the RACH configuration in which the subframe numbers of RO in a frame are 4 and 9, after adjusting the subframe numbers ρ∈{4, 9} to (ρ-6)mod10, the new subframe numbers of RO are (4-6)mod10=8 and (9-6)mod10=3.

[0090] For example, as shown in FIG. 5c, which is different from FIG. 5a in that there is a second TDD slot mode period P2=5 ms, and further Ps=P+P2=10 ms. In the 5 subframes contained in the period P2, the first subframe is a D subframe, the next three subframes are SBFD subframes, and the last subframe is a U subframe. Since the association period Pa=10 ms=P0, according to the predefined calculation rule of the offset parameter, a=9th subframe and β=8th subframe, and Δ=1. For the RACH configuration in which the subframe numbers of RO in a frame are 4 and 9, after adjusting the subframe numbers ρ∈{4, 9} to (ρ-1)mod10, the new subframe numbers of RO are (4-1)mod10=3 and (9-1)mod10=8.

[0091] For example, as shown in FIG. 5d, which is different from FIG. 5c, the TDD slot mode period P = P2= 10 ms, and further Ps= P+P2= 20 ms. Since the association period Pa= 20 ms≠ P0, according to the calculation rules of the offset parameters under Pa≠ P0, 1) a = subframe 9, β = subframe 6, Δ = 3; rule 2) a = subframe 9, β = subframe 3, Δ = 6; rule 3) a = subframe 9, β = subframe 6 for odd frames, and a = subframe 9, β = subframe 3 for even frames. For the RACH configuration in which the subframe numbers in which the ROs are located are 4 and 9 in a frame:

[0092] Under rule 1), after adjusting the subframe numbers ρ∈{4, 9} to (ρ-3)mod10, the new subframe numbers in which the ROs are located are 1 and 6, and this is applied to all frames in which the ROs are located;

[0093] Under rule 2), after adjusting the subframe numbers ρ∈{4, 9} to (ρ-6)mod10, the new subframe numbers in which the ROs are located are 8 and 3, and this is applied to all frames in which the ROs are located;

[0094] Under rule 3), after adjusting the subframe numbers ρ∈{4, 9} to (ρ-3)mod10, the new subframe numbers in which the ROs are located are 1 and 6, and this is applied to odd frames in which the ROs are located, and after adjusting the subframe numbers ρ∈{4, 9} to (ρ-6)mod10, the new subframe numbers in which the ROs are located are 8 and 3, and this is applied to even frames in which the ROs are located.

[0095] For example, as shown in FIG. 5e, in this embodiment, the frame period P0= 10 ms, the application frequency band is FR2, the reference SCS is 60 kHz (N = 40), and the single TDD slot mode period is P = Ps= 2.5 ms. Since the association period Pa= 10 ms = P0, according to the predefined offset parameter calculation rule a = subframe 39, β = subframe 36, Δ = 3. For the RACH configuration in which the subframe numbers in which the ROs are located are 9, 19, 29, and 39 in a frame, after adjusting the subframe numbers ρ∈{9, 19, 29, 39} to (ρ-3)mod40, the new subframe numbers in which the ROs are located are 6, 16, 26, and 36.

[0096] In some embodiments, when the adjustment reference point β is the subframe (or slot) in which the last SBFD symbol is located within the frame period P0, the specific implementation is as shown in FIG. 5f.

[0097] For example, as shown in FIG. 5f, which is different from FIG. 5b, in the 10 subframes contained in the period P, there are mixed subframes composed of U symbols and SBFD symbols. Based on the adjustment reference point β of the present scheme being subframe 3 and a being subframe 9, Δ = 6.

[0098] (II) Mirror and then forward cyclic shift - shift from left to right

[0099] wherein for each RO subframe (slot) number ρ in Table A or Table B, ρ is first adjusted to ρ1=N-1-ρ, N being the total number of subframes (or slots) in a frame.

[0100] When Pa=P0, the offset parameter Δ is equal to the subframe (slot) interval between the first subframe (or slot) α and the adjustment reference point β in the system frame period P0. Specifically, ρ1 is further adjusted to ρ2=(ρ1+Δ) mod N.

[0101] When Pa≠P0, the offset parameter Δ has three options:

[0102] The offset parameter Δ is equal to the subframe (or slot) interval between the first subframe (or slot) α and the adjustment reference point β in the odd frame period P0. Specifically, ρ1 is further adjusted to ρ2=(ρ1+Δ) mod N.

[0103] The offset parameter Δ is equal to the subframe (or slot) interval between the first subframe (or slot) α and the adjustment reference point β in the even frame period P0. Specifically, ρ1 is further adjusted to ρ2=(ρ1+Δ) mod N.

[0104] The offset parameters Δ1 and Δ2 are equal to the subframe (or slot) interval between the first subframe (or slot) α and the adjustment reference point β in the odd and even frame periods P0, respectively. Specifically, ρ1 is further adjusted to ρ2=(ρ1+Δ1) mod N and ρ2=(ρ1+Δ2) mod N for the odd and even frames, respectively.

[0105] wherein in any of the above cases, β and α are in the same frame period.

[0106] In some embodiments, when the adjustment reference point β is the first SBFD subframe (or slot) in the system frame period P0 (all symbols in this subframe / slot are SBFD symbols), the implementation is as shown in FIG. 6a.

[0107] For example, as shown in FIG. 6a, the association period Pa=10 ms=P0, according to the calculation rule of the offset parameter under Pa=P0, α is subframe 0 and β is subframe 2, then Δ=2. For the RACH configuration in which the RO is in subframes 4 and 9, first adjust the subframe number ρ∈{4, 9} to ρ1∈{5, 0} according to the relationship ρ1=9-ρ, and then continue to adjust the subframe number ρ1 according to the relationship ρ2=(ρ1+2) mod 10, to obtain the new subframe numbers of the RO as 7 and 2.

[0108] In some embodiments, when the adjustment reference point β is the subframe (or slot) in which the first SBFD symbol is located in the system frame period P0, the implementation is as shown in FIG. 6b.

[0109] For example, as shown in FIG. 6b, the association period Pa=10 ms=P0, according to the calculation rule of the offset parameter under Pa=P0, a is subframe 0, β is subframe 1, and Δ=1. For the RACH configuration indicating that the subframe numbers in which the RO is located are 4 and 9, the subframe number ρ∈{4, 9} is first adjusted to ρ1∈{5, 0} according to the relationship ρ1=9-ρ, and then the subframe number ρ1is further adjusted according to the relationship ρ2=(ρ1+1)mod10, and the new subframe numbers in which the RO is located are 6 and 1.
