Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a frequency domain location determination method, device, and processor-readable storage medium. Background Technology

[0002] Before the introduction of Subband Full Duplex (SBFD), the terminal (UE) could determine the frequency domain position of the Random Access Channel Occasion (RO) in the uplink (UL) symbol based on parameters configured on the network side. The network side typically configured the Random Access Channel (RACH) resources at both ends of a portion of the bandwidth (BWP), and the remaining UL resources could be used for uplink data channel transmission, avoiding the impact of resource segmentation on the data channel transmission performance.

[0003] However, in the SBFD system, if the SBFD UE still uses the existing configuration (legacy RACH configuration) to perform random access on the RO of the SBFDDL symbol, the frequency domain resources determined according to the legacy RACH configuration are likely not within the frequency domain range of the uplink subband (UL subband) on the SBFDDL symbol, thus making it impossible to perform random access.

Figure 1a As shown, it includes multiple terminals 11 and network-side devices (including access network devices 12 and core network devices 13), wherein:

Core network functions (BSF), application functions (AF), etc. It should be noted that this application embodiment only uses core network equipment in the NR system as an example for description, and does not limit the specific type of core network equipment.

[0308] In this embodiment, the network side and the terminal can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multiple-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or it can be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0309] To better understand the technical solution of this application, the following will be introduced first:

[0310] 5G NR supports Time Division Duplex (TDD) and Frequency Division Duplex (FDD), which refer to two duplex communication modes in mobile communication technology. TDD stands for Time Division Duplex, and FDD stands for Frequency Division Duplex. In TDD mode, transmission and reception occur at different times on the same frequency channel (carrier), using time to distinguish uplink and downlink transmission resources. In FDD mode, transmission and reception occur simultaneously on different frequency channels, using frequency to distinguish uplink and downlink transmission resources.

[0311] Rel-19 supports full-duplex with non-overlapping subbands, meaning a base station can simultaneously transmit and receive within a single frequency band / carrier / BWP using different subbands, without overlap between the subbands used for transmission and reception. For example... Figure 1b As shown, the uplink subband exists in some symbols and does not overlap with other frequency domain resources.

[0312] Prior to the introduction of SBFD in Release 19, the network side could configure UL subbands on symbols set to DL or flexible in TDD-UL-DL-ConfigCommon. Symbols with configured UL subbands were SBFD symbols, and only SBFD-aware UEs could perform uplink transmissions on the subband. Symbols without configured UL subbands (including those set to UL in TDD-UL-DL-ConfigCommon) were non-SBFD symbols, and all UEs transmitted according to the configured symbol direction.

[0313] The starting RB of a carrier is defined as Common Resource Block (CRB) 0 as a reference point. The network side will configure a maximum of 4 Physical Resource Blocks (BWPs) on the carrier, and a UE operates within one BWP. The starting frequency domain position of a BWP is determined based on the number of RBs offset from CRB0, and the starting RB of a BWP is defined as PRB0. Therefore, the Physical Resource Block (PRB) index and the CRB index can be converted to each other, i.e., in, This specifies the offset of the BWP start RB relative to the carrier start RB. The network side configures a set of RACH resources for legacy UEs via the RACH-ConfigCommon IE. This includes the msg1-FrequencyStart parameter, which determines the offset of the lowest frequency domain RO relative to PRB0 (BWP start RB). Additionally, the network side configures the number of ROs that can be transmitted via FDM at a time domain location via the msg1-FDM parameter. When configuring these two frequency domain-related parameters, the network side must ensure that all RO frequency domain locations fall within the bandwidth of the UL BWP.

[0314] Furthermore, in the R19 SBFD project, the network side configures a UL subband within the SBFD symbol. The frequency domain position occupied by the UL subband is configured based on the carrier's start position CRB0. If SBFD is to be implemented within a BWP, the network side needs to ensure that the UL subband is configured within the UL BWP bandwidth. In this case, the CRB index of the UL subband's frequency domain position can be converted to the PRB index within that BWP.

[0315] On the network side, RACH resources are typically configured at both ends of the BWP, and the remaining UL resources can be used for uplink data channel transmission, avoiding resource segmentation from affecting data channel transmission performance. However, in SBFD systems, especially in DUD configurations where the UL subband's frequency domain position is located in the middle of the BWP, if the SBFD UE uses legacy RACH configuration to perform random access on a new RO determined on the SBFD DL symbol, the frequency domain resources determined according to the frequency domain resource calculation method on non-SBFD symbols are likely not within the UL subband's frequency domain. In this case, there are no additional usable RO resources on the SBFD DL symbol.

[0316] The frequency domain location determination method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0317] Please see Figure 2 This application provides a frequency domain location determination method, which is executed by a terminal and includes the following steps:

[0318] Step 201: The terminal determines the target frequency domain location of the RO resource on the SBFD DL symbol based on the first information;

[0319] Among them, the first piece of information is related to the starting position of the frequency domain.

[0320] In this embodiment, the target frequency domain location of the RO resource on the SBFD DL symbol is determined based on first information related to the frequency domain start position. This provides a new method for determining the RO frequency domain resource on the SBFD DL symbol, ensuring the existence of a valid RO frequency domain start position on the SBFD DL, increasing the transmission opportunity for the SBFD UE to send PRACH, and reducing the random access latency of the SBFD UE. Furthermore, the RO on the SBFD DL symbol is only available to the SBFD UE, avoiding conflicts with legacy UEs using existing configurations, and improving the probability of successful random access for the SBFD UE.

[0321] It should be noted that the SBFD DL symbol mentioned in this application refers to "SBFD symbol with system information configured as downlink symbol", and is uniformly and simply described as "SBFD DL symbol" in the text.

[0322] The aforementioned frequency domain start position can be a frequency domain position related to msg1-FrequencyStart, or a frequency domain position related to the UL subband configured on the network side, such as the frequency domain start position of the UL subband. Specifically, the UL subband is the uplink frequency domain range in the SBFD subband configured by the network side in the SBFD symbol.

[0323] The target frequency domain location mentioned above can be either the starting position of the target frequency domain of the RO resource or the ending position of the target frequency domain of the RO resource.

[0324] In one possible implementation, the terminal determines the target frequency domain location of the RO resource on the SBFD DL symbol based on the first information, including:

[0325] (1) The terminal determines the target frequency domain location of the RO resource based on whether the first information is within the frequency domain range of the target uplink subband;

[0326] The aforementioned target uplink subband refers to the UL subband configured on the network side. By determining whether the first information is within the UL subband range, the target frequency domain position of the RO resource on the SBFD DL symbol is determined.

[0327] Or (2) The terminal determines the target frequency domain location of the RO resource based on the first information.

[0328] In one possible implementation, the first information includes at least one of the following:

[0329] (1) Location of the first frequency domain;

[0330] (2) Second frequency domain position;

[0331] (3) Preset functions;

[0332] The second frequency domain position is the frequency domain end position of the RO resource determined based on the first frequency domain position. The specific method for determining the second frequency domain position can adopt the existing method for determining the frequency domain end position of RO resources, such as: determining the frequency domain end position of the overall RO resource based on the number of frequency domain RBs occupied by one RO and the number of ROs that allow FDM transmission at one time domain position configured on the network side.

[0333] The aforementioned first frequency domain location is at least one of the following:

[0334] (1) The starting position of the frequency domain determined by the first parameter;

[0335] (2) The starting position of the frequency domain determined by the first parameter and the first index; for example, the starting position of the frequency domain is the starting position of the frequency domain determined by the first parameter plus the first index.

[0336] Specifically, when the first frequency domain position is the frequency domain start position determined according to the first parameter, the first parameter is used to determine the offset of the lowest RO in the frequency domain relative to the frequency domain start position of the target BWP. For example, the first parameter can be the msg1-FrequencyStart parameter configured on the network side, which is used to determine the offset of the lowest RO in the frequency domain relative to PRB0 (BWP start RB). When the first frequency domain position is the frequency domain start position determined according to the first parameter and the first index, the first parameter is used to determine the offset of the lowest RO in the frequency domain relative to the UL subband frequency domain start position. For example, the first parameter can be the msg1-FrequencyStart parameter configured on the network side, which is used to determine the offset of the lowest RO in the frequency domain relative to the UL subband frequency domain start position. The first index is the index of the frequency domain start position of the target uplink subband converted to the index of the frequency domain position in the target BWP. For example, the UL subband start CRB index configured on the network side is converted to the PRB index in the target BWP relative to the target BWP start position. For specific conversion methods, please refer to the relevant content above.

[0337] The target BWP mentioned above can be a UL BWP or a DL BWP.

[0338] In one possible implementation, the terminal determines the target frequency domain location of the RO resource based on whether the first information is within the frequency domain range of the target uplink subband, including at least one of the following:

[0339] (1) The terminal determines the target frequency domain location of the RO resource based on whether the first frequency domain location is within the frequency domain range of the target uplink subband;

[0340] The terminal determines a frequency domain start position based on the first parameter, or based on the first parameter and the first index, and determines the target frequency domain position of the RO resource by judging whether the frequency domain start position is within the frequency domain range occupied by the UL subband.

[0341] (2) The terminal determines the target frequency domain location of the RO resource based on whether the second frequency domain location is within the frequency domain range of the target uplink subband;

[0342] The terminal determines the second frequency domain position from the first frequency domain position, that is, determines a frequency domain end position. Based on whether the frequency domain end position is within the frequency domain range occupied by the UL subband, the target frequency domain position of the RO resource is determined.

[0343] (3) The terminal determines the target frequency domain location of the RO resource based on whether the first frequency domain range related to the first frequency domain location overlaps with the frequency domain range of the target uplink sub-band.

[0344] The first frequency domain range is the frequency domain range determined based on the first frequency domain position and the second frequency domain position.

[0345] The terminal determines a first frequency domain range based on the first frequency domain location and the second frequency domain location. It then determines the target frequency domain location of the RO resource by judging whether the first frequency domain range overlaps with the frequency domain range occupied by the UL subband.

[0346] (4) The terminal determines the target frequency domain location of the RO resource based on the first indication information;

[0347] In this embodiment, the terminal first determines the first frequency domain position, and then determines the target frequency domain position of the RO resource according to the first indication information. The first indication information is used to indicate whether the terminal needs to adjust the starting frequency domain position of the RO resource. If the indication is disabled, the terminal determines the first frequency domain position as the target starting frequency domain position; if the indication is enabled, the terminal determines the target frequency domain position according to a preset function.

[0348] (5) The terminal determines the target frequency domain location of the RO resource by checking whether there is a valid RO on the SBFD symbol configured as a flexible symbol based on system information.

[0349] In this embodiment, the terminal first determines the first frequency domain position, and then determines the target frequency domain position of the RO resource based on whether there is a valid RO on the flexible symbol. If there is a valid RO on the flexible symbol, the terminal determines the first frequency domain position as the target starting frequency domain position; if there is no valid RO on the flexible symbol, the terminal determines the target frequency domain position according to a preset function.

[0350] In one possible implementation, the terminal determines the target frequency domain location of the RO resource based on whether the first frequency domain location is within the frequency domain range of the target uplink subband, including:

[0351] (1.1) If the first frequency domain position is within the frequency domain range of the target uplink subband, the terminal determines the target frequency domain starting position of the RO resource as the first frequency domain position;

[0352] If the first frequency domain position is within the frequency domain range of the target uplink subband, it means that the frequency domain start position determined by the terminal according to the first parameter or the first parameter and the first index is within the frequency domain range occupied by the UL subband. Therefore, the frequency domain start position is determined as the target frequency domain start position of the RO resource, thereby ensuring that there is an available RO within the frequency domain range occupied by the UL subband.

[0353] Furthermore, the target frequency domain end position of the RO resource can be determined in the same way as the second frequency domain position, based on the target frequency domain start position of the RO resource.

[0354] (1.2) If the first frequency domain position is not within the frequency domain range of the target uplink subband, the terminal determines the target frequency domain start position or target frequency domain end position of the RO resource according to the preset function.

[0355] If the first frequency domain position is not within the frequency domain range of the target uplink subband, it means that the frequency domain start position determined by the terminal according to the first parameter or the first parameter and the first index is not within the frequency domain range occupied by the UL subband. At this time, the target frequency domain start position or target frequency domain end position of the RO resource is calculated using a preset function to ensure that there is an available RO within the frequency domain range occupied by the UL subband.

[0356] In one possible implementation, the terminal determines the target frequency domain location of the RO resource based on whether the second frequency domain location is within the frequency domain range of the target uplink subband, including:

[0357] (2.1) When the second frequency domain position is within the frequency domain range of the target uplink subband, the terminal determines the target frequency domain starting position of the RO resource as the first frequency domain position;

[0358] If the second frequency domain position is within the frequency domain range of the target uplink subband, it means that the frequency domain end position determined by the terminal based on the first frequency domain position is within the frequency domain range occupied by the UL subband. Therefore, the first frequency domain position is determined as the target frequency domain start position of the RO resource, thereby ensuring that there is an available RO within the frequency domain range occupied by the UL subband.

[0359] Furthermore, the target frequency domain end position of the RO resource can be determined in the same way as the second frequency domain position, based on the target frequency domain start position of the RO resource.

[0360] (2.2) If the second frequency domain position is not within the frequency domain range of the target uplink subband, the terminal determines the target frequency domain start position or target frequency domain end position of the RO resource according to the preset function.

[0361] If the second frequency domain position is not within the frequency domain range of the target uplink subband, it means that the frequency domain end position calculated by the terminal based on the first frequency domain position is not within the frequency domain range occupied by the UL subband. At this time, a preset function is used to calculate the target frequency domain start position or target frequency domain end position of the RO resource, thereby ensuring that there is a usable RO within the frequency domain range occupied by the UL subband.

[0362] In one possible implementation, the terminal determines the target frequency domain location of the RO resource based on whether a first frequency domain range associated with the first frequency domain location overlaps with the frequency domain range of the target uplink subband, including:

[0363] (3.1) When the first frequency domain range overlaps with the frequency domain range of the target uplink subband, the terminal determines the target frequency domain starting position of the RO resource as the first frequency domain position.

[0364] If the first frequency domain range overlaps with the frequency domain range of the target uplink subband, it means that the frequency domain range determined by the terminal based on the first and second frequency domain positions overlaps with the frequency domain range occupied by the UL subband. Therefore, the first frequency domain position is determined as the target frequency domain starting position of the RO resource, thereby ensuring that there is an available RO within the frequency domain range occupied by the UL subband.

[0365] Furthermore, the target frequency domain end position of the RO resource can be determined in the same way as the second frequency domain position, based on the target frequency domain start position of the RO resource.

[0366] (3.2) If the first frequency domain range does not overlap with the frequency domain range of the target uplink sub-band, the terminal determines the target frequency domain start position or target frequency domain end position of the RO resource according to the preset function.

[0367] If the first frequency domain range does not overlap with the frequency domain range of the target uplink subband, it means that the frequency domain range determined by the terminal based on the first and second frequency domain positions does not overlap with the frequency domain range occupied by the UL subband. Therefore, the first frequency domain position is determined as the target frequency domain start position of the RO resource. At this time, a preset function is used to calculate the target frequency domain start position or target frequency domain end position of the RO resource, thereby ensuring that there is a usable RO within the frequency domain range occupied by the UL subband.

[0368] In one possible implementation, the terminal determines the target frequency domain location of the RO resource based on the first indication information, including:

[0369] (4.1) When the first indication information indicates that the RO resource is disabled, the terminal determines the target frequency domain starting position of the RO resource as the first frequency domain position.

[0370] If the first indication information indicates that it is not enabled, it means that the terminal does not need to adjust the starting frequency domain position of the RO resource. Therefore, the terminal determines the starting frequency domain position based on the first parameter or the first parameter and the first index, and determines the starting frequency domain position as the target frequency domain starting position of the RO resource, thereby ensuring that there is a usable RO within the frequency domain range occupied by the UL subband.

[0371] Furthermore, the target frequency domain end position of the RO resource can be determined in the same way as the second frequency domain position, based on the target frequency domain start position of the RO resource.

[0372] (4.2) When the first indication information indicates that the RO resource is enabled, the terminal determines the target frequency domain start position or target frequency domain end position according to the preset function.

[0373] If the first indication message indicates that it is not enabled, it means that the terminal needs to adjust the starting frequency domain position of the RO resource. At this time, the preset function is used to calculate the target frequency domain starting position or target frequency domain ending position of the RO resource, so as to ensure that there is a usable RO within the frequency domain range occupied by the UL subband.

[0374] In one possible implementation, the terminal determines the target frequency domain location of the RO resource based on whether a valid RO exists on the SBFD symbol configured as a flexible symbol according to system information, including:

[0375] (5.1) When there is a valid RO on the SBFD symbol configured as flexible in the system information, the terminal determines the target frequency domain starting position of the RO resource as the first frequency domain position.

[0376] If there is a valid RO on the SBFD symbol configured as flexible in the system information, it means that the frequency domain start position determined according to the first parameter or the first parameter and the first index can satisfy the requirement that there is a usable RO within the frequency domain occupied by the UL subband. Therefore, the frequency domain start position is determined as the target frequency domain start position of the RO resource, thereby ensuring that there is a usable RO within the frequency domain occupied by the UL subband.

[0377] Furthermore, the target frequency domain end position of the RO resource can be determined in the same way as the second frequency domain position, based on the target frequency domain start position of the RO resource.

[0378] (5.2) If there is no valid RO on the SBFD symbol configured as flexible in the system information, the terminal determines the target frequency domain start position or target frequency domain end position of the RO resource according to the preset function.

[0379] If there is no valid RO on the SBFD symbol configured as flexible, it means that the frequency domain start position determined by the first parameter or the first parameter and the first index cannot satisfy the requirement that there is a usable RO within the frequency domain occupied by the UL subband. In this case, the target frequency domain start position or target frequency domain end position of the RO resource is calculated using a preset function to ensure that there is a usable RO within the frequency domain occupied by the UL subband.

[0380] In one possible implementation, the first frequency domain range overlaps with the frequency domain range of the target uplink subband, including:

[0381] (1) The frequency domain resources that overlap with the frequency domain range of the target uplink subband are at least one resource block RB;

[0382] (2) The frequency domain resources that overlap with the frequency domain range of the first frequency domain range and the frequency domain range of the target uplink subband are the frequency domain resources occupied by at least one RO.

[0383] In one possible implementation, the terminal determines the target frequency domain location of the RO resource based on the first information, including:

[0384] The terminal determines the target frequency domain start position or target frequency domain end position of the RO resource according to a preset function.

[0385] In this embodiment, the terminal can directly determine the target frequency domain start position or target frequency domain end position of the RO resource based on a preset function, without having to perform the judgment related to the frequency domain range of the target uplink subband described above.

[0386] In one possible implementation, the preset function is associated with at least one of the first parameter, the first index, the bandwidth of the target uplink subband, and the bandwidth of the target BWP.

[0387] In this embodiment of the application, the preset function includes any one of the following:

[0388] (1) The terminal determines the target frequency domain start position of the RO resource according to the first function;

[0389] (2) The terminal determines the target frequency domain end position of the RO resource according to the second function;

[0390] The first function includes one arbitrary term:

[0391] (1.1)(first parameter mod target uplink subband bandwidth) + first index;

[0392] That is, (msg1 - FrequencyStart mod UL subband bandwidth) + first index;

[0393] (1.2)((first index + first parameter) mod target uplink subband bandwidth) + first index;

[0394] That is, ((first index + msg1 - FrequencyStart) mod UL subband bandwidth) + first index;

[0395] (1.3)

[0396] That is, round up ((msg1 - FrequencyStart / BWP bandwidth) × UL subband bandwidth) + first index;

[0397] (1.4)

[0398] That is, round down to ((msg1 - FrequencyStart / BWP bandwidth) × UL subband bandwidth) + first index;

[0399] (1.5) First Index

[0400] The second function includes:

[0401] First index + target uplink subband bandwidth - 1.

[0402] That is, the first index + UL subband bandwidth - 1.

[0403] Please see Figure 3This application provides a frequency domain location determination method, which is executed by a network-side device and includes the following steps:

[0404] Step 301: The network-side device determines the target frequency domain location of the RO resource on the SBFD DL symbol based on the first information;

[0405] Among them, the first piece of information is related to the starting position of the frequency domain.

[0406] It should be noted that the network-side device, as the counterpart execution entity interacting with the terminal, needs to use the same method as the terminal side when determining the target frequency domain location of the RO resource. This is to ensure that the frequency domain locations determined by both sides are the same. The method for determining the target frequency domain location of the RO resource should be understood in the same way by both sides. Therefore, the network-side method can be understood by referring to the relevant description of the terminal-side method, and will not be repeated here.

[0407] In one possible implementation, the network-side device determines the target frequency domain location of the RO resource on the SBFD DL symbol based on the first information, including:

[0408] The network-side device determines the target frequency domain location of the RO resource based on whether the first information is within the frequency domain range of the target uplink subband;

[0409] or,

[0415] The second frequency domain position is the frequency domain end position of the RO resource determined based on the first frequency domain position;

[0416] The first frequency domain location is at least one of the following:

[0417] The starting position of the frequency domain is determined based on the first parameter;

[0418] The frequency domain start position is determined based on the first parameter and the first index;

[0419] The first parameter is used to determine the offset of the lowest frequency domain position RO relative to the frequency domain start position of the target BWP, or the first parameter is used to determine the offset of the lowest frequency domain position RO relative to the frequency domain start position of the target uplink subband, and the first index is the index of the frequency domain position of the target uplink subband converted to the index of the frequency domain position in the target BWP.

[0423] The network-side device determines the target frequency domain location of the RO resource based on whether the first frequency domain range related to the first frequency domain location overlaps with the frequency domain range of the target uplink sub-band.

[0424] The network-side device determines the target frequency domain position of the RO resource based on the first indication information. The first indication information is used to indicate whether the terminal needs to adjust the starting frequency domain position of the RO resource. If the indication is disabled, the terminal determines the first frequency domain position as the target starting frequency domain position. If the indication is enabled, the terminal determines the target frequency domain position according to a preset function.

[0425] The network-side device determines the target frequency domain location of the RO resource based on whether there is a valid RO on the SBFD symbol configured as a flexible symbol according to system information. If there is a valid RO on the flexible symbol, the terminal determines the first frequency domain location as the target starting frequency domain location. If there is no valid RO on the flexible symbol, the terminal determines the target frequency domain location according to a preset function.

[0426] The first frequency domain range is the frequency domain range determined based on the first frequency domain position and the second frequency domain position.

[0427] In one possible implementation, the network-side device determines the target frequency domain location of the RO resource based on whether the first frequency domain location is within the frequency domain range of the target uplink subband, including:

[0428] If the first frequency domain position is within the frequency domain range of the target uplink subband, the network-side device determines the target frequency domain starting position of the RO resource as the first frequency domain position;

[0431] If the second frequency domain position is within the frequency domain range of the target uplink subband, the network-side device determines the target frequency domain starting position of the RO resource as the first frequency domain position;

[0432] If the second frequency domain position is not within the frequency domain range of the target uplink subband, the network-side device determines the target frequency domain start position or target frequency domain end position of the RO resource according to a preset function.

[0433] In one possible implementation, the network-side device determines the target frequency domain location of the RO resource based on whether a first frequency domain range associated with the first frequency domain location overlaps with the frequency domain range of the target uplink subband, including:

[0434] When the first frequency domain range overlaps with the frequency domain range of the target uplink subband, the network-side device determines the target frequency domain starting position of the RO resource as the first frequency domain position.

[0435] If the first frequency domain range does not overlap with the frequency domain range of the target uplink subband, the network-side device determines the target frequency domain start position or target frequency domain end position of the RO resource according to a preset function.

[0436] In one possible implementation, the network-side device determines the target frequency domain location of the RO resource based on the first indication information, including:

[0437] When the first indication information indicates that the RO resource is disabled, the network-side device determines the target frequency domain starting position of the RO resource as the first frequency domain position.

[0438] When the first instruction information indicates that it is enabled, the network-side device determines the target frequency domain start position or target frequency domain end position of the RO resource according to a preset function.

[0439] In one possible implementation, the network-side device determines the target frequency domain location of the RO resource based on whether a valid RO exists on an SBFD symbol configured as a flexible symbol according to system information, including:

[0440] If a valid RO exists on an SBFD symbol configured as a flexible symbol in the system information, the network-side device determines the target frequency domain starting position of the RO resource as the first frequency domain position.

[0441] If there is no valid RO on the SBFD symbol configured as flexible in the system information, the network-side device determines the target frequency domain start position or target frequency domain end position of the RO resource according to a preset function.

[0442] In one possible implementation, the first frequency domain range overlaps with the frequency domain range of the target uplink subband, including:

[0443] The frequency domain resources that overlap with the frequency domain range of the target uplink subband are at least one resource block (RB).

[0444] or,

[0445] The frequency domain resources that overlap with the frequency domain range of the first frequency domain range and the target uplink subband are frequency domain resources occupied by at least one RO.

[0446] In one possible implementation, the network-side device determines the target frequency domain location of the RO resource based on the first information, including:

[0447] The network-side device determines the target frequency domain start position or target frequency domain end position of the RO resource according to a preset function.

[0448] In one possible implementation, the preset function is associated with at least one of the first parameter, the first index, the bandwidth of the target uplink subband, and the bandwidth of the target BWP.

[0449] The frequency domain location determination method provided in this application is illustrated below through several embodiments:

[0450] Example 1: Determining the target frequency domain location based on whether the first frequency domain location is within the UL subband frequency domain range

[0451] In this embodiment, the target frequency domain position is the starting position of the RO resource on the SBFD DL symbol. The UE first calculates the first frequency domain position, which is either the msg1-FrequencyStart configured by the network side or the sum of the first index and msg1-FrequencyStart. When the first frequency domain position is the sum of the first index and msg1-FrequencyStart, msg1-FrequencyStart is reinterpreted in the SBFD DL symbol as an offset relative to the starting frequency domain position of the UL subband. Since the network side configures the UL subband frequency domain range based on carrier start CRB 0, it is necessary to convert the frequency domain position of the UL subband to the PRB index within the BWP. In this invention, the CRB index of the UL subband frequency domain starting position can be converted to the first index based on the frequency domain starting position of the UL BWP, or it can be converted to the first index based on the frequency domain starting position of the DL BWP. In this embodiment, the conversion of the UL subband starting frequency domain position to the first index based on the UL BWP is described. The CRB index of the starting position of the UL subband in the frequency domain is 70. The offset of the starting position of the UL BWP in the frequency domain relative to CRB 0 is 40. Therefore, the PRB index of the UL subband in the UL BWP is 70-40=30, that is, the first index is PRB 30.

[0452] In this embodiment, it is assumed that the UL BWP bandwidth is 100 RBs, the UL BWP frequency domain range is PRB 0 to 99, the UL subband bandwidth configured on the network side is 40 RBs, and starting from the first index PRB 30, the UL subband frequency domain range is PRB 30 to 69.

[0453] When the first frequency domain position is the msg1-FrequencyStart configured on the network side, assuming msg1-FrequencyStart is 35, then the first frequency domain position PRB 35 is within the UL subband frequency domain range of PRB 30 to 69, and the target frequency domain position is the first frequency domain position. The UE determines the lowest RO starting frequency domain position index on the SBFD DL symbol as PRB 35.

[0454] Alternatively, if the first frequency domain position is the sum of the first index and msg1-FrequencyStart, assuming msg1-FrequencyStart is 10, the first frequency domain position is 10 + 30 = 40. PRB 40 is within the UL subband frequency domain range of PRB 30 to 69, and the target frequency domain position is the first frequency domain position. The UE determines the lowest RO starting frequency domain position index on the SBFD DL symbol as PRB 40.

[0455] like Figure 4a As shown, if the first frequency domain position determined according to any of the above methods is within the UL subband frequency domain, the starting position of the RO resource on the SBFD DL symbol is the first frequency domain position, and no enhancement is required. The ending position of the overall RO resource, determined based on the number of ROs allowed for FDM transmission at a time domain position, can exceed the UL subband frequency domain. Subsequently, the RO validation rules will be used to further determine that only ROs falling within the UL subband frequency domain are valid ROs.

[0456] When the first frequency domain position is the msg1-FrequencyStart configured on the network side, assuming the msg1-FrequencyStart configured on the network side is 10, the first frequency domain position PRB 10 is not within the UL subband frequency domain range of PRB 30 to 69. In this case, the UE needs to calculate the lowest RO starting frequency domain position index on the SBFD DL symbol according to the function.

[0457] If function 1 is used, the target starting index is (10 mod 40) + 30 = 40, and the starting frequency domain position index of the lowest RO on the SBFD DL symbol is PRB 40. If function 2 is used, the target starting index is ((10 + 30) mod 30) + 30 = 30, meaning the starting frequency domain position index of the lowest RO on the SBFD DL symbol is PRB 30. Function 3 directly determines the target frequency domain position as the first index, meaning the starting frequency domain position of the lowest RO on the SBFD DL symbol starts from the starting frequency domain position PRB 30 of the UL subband. If function 4 is used, the target starting index is 10 / 100 * 40 + 30 = 34, where 34 is an integer and does not require further rounding, meaning the starting frequency domain position index of the lowest RO on the SBFD DL symbol is PRB 34.

[0458] like Figure 4b As shown, since the first frequency domain position determined above is lower than the starting position of the UL subband frequency domain, it is necessary to calculate using any of the above functions to move the starting position of the legacy RO resource on the SBFD DL symbol into the UL subband frequency domain range. The ending position of the overall RO resource, determined by the number of ROs allowed for FDM transmission at a given time domain position, can extend beyond the UL subband frequency domain range.

[0459] Alternatively, if the first frequency domain position is the sum of the first index and msg1-FrequencyStart, assuming the network-side configured msg1-FrequencyStart is 70, the first frequency domain position is 70 + 30 = 100. The first frequency domain position PRB 100 is not within the UL subband frequency domain range of PRB 30–69. In this case, the UE needs to calculate the lowest RO starting frequency domain position index on the SBFD DL symbol according to the function.

[0460] If function 1 is used, the target starting index is (70 mod 40) + 30 = 60, and the starting frequency domain position index of the lowest RO on the SBFD DL symbol is PRB 60; if function 2 is used, the target starting index is ((70 + 30) mod 40) + 30 = 50, that is, the starting frequency domain position index of the lowest RO on the SBFD DL symbol is PRB 50; function 3 directly determines the target frequency domain position as the first index, that is, the starting frequency domain position of the lowest RO on the SBFD DL symbol starts from the starting frequency domain position PRB 30 of the UL subband; if function 4 is used, the target starting index is 70 / 100*40 + 30 = 58, 584 is an integer and does not need further rounding, that is, the starting frequency domain position index of the lowest RO on the SBFD DL symbol is PRB 58.

[0461] like Figure 4c As shown, since the first frequency domain position determined above is higher than the end position of the UL subband frequency domain, it is necessary to calculate using any of the above functions to move the start position of the legacy RO resource on the SBFD DL symbol into the UL subband frequency domain range. Similarly, the end position of the overall RO resource, determined by the number of ROs allowed for FDM transmission at a given time domain position, can also exceed the UL subband frequency domain range.

[0462] Example 2: Determining the target frequency domain location based on whether the second frequency domain location is within the UL subband frequency domain range.

[0463] In this embodiment, the target frequency domain position is the start or end position of the RO resource on the SBFD DL symbol. The UE first calculates the first frequency domain position, which is either the msg1-FrequencyStart configured by the network side or the sum of the first index and msg1-FrequencyStart. Then, the second frequency domain position is determined based on the first frequency domain position. The first frequency domain position msg1-FrequencyStart, or the sum of the first index and msg1-FrequencyStart, determines the frequency domain start position of the RO resource. The frequency domain end position of the overall RO resource, i.e., the second frequency domain position, also needs to be determined based on the number of RBs occupied by one RO and the number of ROs allowed for FDM transmission at one time domain position configured by the network side. When the first frequency domain position is determined based on the sum of the first index and msg1-FrequencyStart, msg1-FrequencyStart is reinterpreted in the SBFD DL symbol as an offset relative to the start frequency domain position of the UL subband. In this embodiment, the CRB index of the starting position of the UL subband frequency domain is 70, and the offset of the starting position of the UL BWP frequency domain relative to CRB 0 is 40. Therefore, the PRB index of the UL subband within the UL BWP is 70-40=30, that is, the first index is PRB 30.

[0464] In this embodiment, it is assumed that the UL BWP bandwidth is 100 RBs, the UL BWP frequency domain range is PRB 0 to 99, the UL subband bandwidth configured on the network side is 40 RBs, and starting from the first index PRB 30, the UL subband frequency domain range is PRB 30 to 69.

[0465] Regardless of whether the first frequency domain position is determined based on msg1-FrequencyStart or the sum of the first index and msg1-FrequencyStart, assuming the first frequency domain position is 20 and the second frequency domain position is 52, then the second frequency domain position PRB 52 falls within the UL subband frequency domain range of PRB 30–69. The target frequency domain position is the starting position of the RO resource on the SBFD DL symbol, which is the first frequency domain position. The UE determines the lowest RO starting frequency domain position index on the SBFD DL symbol as PRB 20.

[0466] like Figure 4dAs shown, if the first frequency domain position determined by any of the above methods is within the UL subband frequency domain, the end position of the RO resource on the SBFD DL symbol is the second frequency domain position, and no enhancement is needed. The starting position of the overall RO resource, i.e., the first frequency domain position, can exceed the UL subband frequency domain. Subsequently, based on the RO validation rules, it will be further determined that only ROs falling within the UL subband frequency domain are valid ROs.

[0467] Regardless of whether the first frequency domain position is determined based on msg1-FrequencyStart or the sum of the first index and msg1-FrequencyStart, assuming the first frequency domain position is 40, one RO occupies 6 RBs, one time domain position allows 8 ROs for FDM transmission, and the second frequency domain position is 87, then the first frequency domain position PRB 87 is not within the UL subband frequency domain range of PRB30~69. In this case, the UE needs to calculate the target frequency domain position according to the function.

[0468] In this embodiment, functions 1 to 4 can be used as in Embodiment 1. In this case, the target frequency domain position is the starting position of the RO resource on the SBFD DL symbol, which will not be elaborated further in this embodiment. Alternatively, function 5 can be used in this embodiment. In this case, the target frequency domain position is the ending position of the RO resource on the SBFD DL symbol, and the target ending index is 30 + 40 - 1 = 69. That is, the ending frequency domain position of the RO resource with the highest frequency domain position on the SBFD DL symbol is aligned with the ending frequency domain position PRB 69 of the UL subband. Figure 4e As shown, when the first frequency domain position determined above is higher than the end position of the UL subband frequency domain, function 5 is needed to align the end position of the legacy RO resource on the SBFD DL symbol with the end position of the UL subband frequency domain.

[0469] Example 3: The UE determines the target frequency domain location based on whether the third frequency domain range overlaps with the UL subband frequency domain range.

[0470] In this embodiment, the target frequency domain position is the start or end position of the RO resources on the SBFD DL symbol. The UE first calculates the first frequency domain position, which is either the msg1-FrequencyStart configured by the network side or the sum of the first index and msg1-FrequencyStart. The first frequency domain position is the start position of the third frequency domain range. Next, the second frequency domain position is determined based on the first frequency domain position. That is, starting from the first frequency domain position, the frequency domain end position of the overall RO resources is determined based on the number of RBs occupied by one RO and the number of ROs allowed for FDM transmission in one time domain position configured by the network side. The second frequency domain position is the end position of the third frequency domain range. When the first frequency domain position is determined based on the sum of the first index and msg1-FrequencyStart, msg1-FrequencyStart is reinterpreted in the SBFD DL symbol as an offset relative to the starting frequency domain position of the UL subband. In this embodiment, the CRB index of the starting position of the UL subband frequency domain is 70, and the offset of the starting position of the ULBWP frequency domain relative to CRB 0 is 40. Therefore, the PRB index of the UL subband within the UL BWP is 70-40=30, that is, the first index is PRB 30.

[0471] In this embodiment, it is assumed that the UL BWP bandwidth is 100 RBs, the UL BWP frequency domain range is PRB 0 to 99, the UL subband bandwidth configured on the network side is 40 RBs, and starting from the first index PRB 30, the UL subband frequency domain range is PRB 30 to 69.

[0472] In this embodiment, the overlap between the third frequency domain range and the UL subband includes four cases. The first is that the first frequency domain position is below the start position of the UL subband, and the second frequency domain position is within the UL subband frequency domain range. The second is that the first frequency domain position is within the UL subband frequency domain range, and the second frequency domain position is above the end position of the UL subband. The third is that the first frequency domain position is below the start position of the UL subband, and the second frequency domain position is above the end position of the UL subband. The fourth is that both the first and second frequency domain positions are within the UL subband range.

[0473] Specifically, such as Figure 4fAs shown, in the first case, regardless of whether the first frequency domain position is determined based on msg1-FrequencyStart or the sum of the first index and msg1-FrequencyStart, assuming the first frequency domain position is 20, one RO occupies 6 RBs, and one time domain position allows FDM transmission of 2 ROs, then the second frequency domain position is 43, and the third frequency domain range is PRB 20~31. This overlaps with the UL subband frequency domain range, with the overlap being PRB 30~31, a total of 2 RBs. The target frequency domain position is the starting position of the RO resources on the SBFD DL symbol. The UE determines the starting frequency domain position index of the RO with the lowest frequency domain position on the SBFD DL symbol as PRB 20.

[0474] Furthermore, assuming that the frequency domain overlap requires at least one RO occupying frequency domain resources, i.e., 6 RBs, and 2 RBs do not meet the condition, then the target frequency domain position needs to be determined according to a preset function. In addition to functions 1 to 5 in Examples 1 to 3, the preset function in this example may also include the number of RBs moved from the target starting frequency domain position to ensure that the frequency domain overlap range has at least one RO. That is, the target starting frequency domain position is moved by 4 RBs to PRB 24.

[0475] like Figure 4g As shown, in the second scenario, assuming the first frequency domain location is 50, one RO occupies 6 RBs, and one time domain location allows 4 ROs for FDM transmission, then the second frequency domain location is 73, and the third frequency domain range is PRB 50~73. This overlaps with the UL subband frequency domain range, specifically PRB 50~69, a total of 20 RBs. The target frequency domain location is the starting position of the RO resources on the SBFD DL symbol. The UE determines the starting frequency domain location index of the lowest frequency domain location on the SBFD DL symbol as PRB50.

[0476] like Figure 4h As shown, in the third case, assuming the first frequency domain position is 25, one RO occupies 12 RBs, and one time domain position allows 4 ROs for FDM transmission, then the second frequency domain position is 72, and the third frequency domain range is PRB 25~72. This overlaps with the UL subband frequency domain range, with the overlapping portion being PRB 30~69, a total of 40 RBs. The target frequency domain position is the starting position of the RO resources on the SBFD DL symbol. The UE determines the starting frequency domain position index of the lowest frequency domain position of the RO on the SBFD DL symbol as PRB20.

[0477] like Figure 4iAs shown, in the fourth case, assuming the first frequency domain position is 40, one RO occupies 6 RBs, and one time domain position allows 4 ROs for FDM transmission, then the second frequency domain position is 63, and the third frequency domain range is PRB 40~63. This overlaps with the UL subband frequency domain range, with the overlapping portion being 24 RBs (PRB 40~63). The target frequency domain position is the starting position of the RO resources on the SBFD DL symbol. The UE determines the starting frequency domain position index of the lowest frequency domain position of the RO on the SBFD DL symbol as PRB40.

[0478] In this embodiment, the non-overlapping of the third frequency domain range and the UL subband includes four cases. The first case is that both the first and second frequency domain positions are lower than the starting position of the UL subband, or both the first and second frequency domain positions are higher than the ending position of the UL subband.

[0479] like Figure 4j As shown, in the first case, assuming the first frequency domain position is 10, one RO occupies 6 RBs, and one time domain position allows FDM transmission of 1 RO, then the second frequency domain position is 15, and the third frequency domain range is PRB 10~15. This does not overlap with the UL subband frequency domain range.

[0480] like Figure 4k As shown, in the second case, assuming the first frequency domain position is 80, one RO occupies 6 RBs, and one time domain position allows FDM transmission of 1 RO, then the second frequency domain position is 85, and the third frequency domain range is PRB 80~85. This does not overlap with the UL subband frequency domain range.

[0481] At this point, the target frequency domain location needs to be determined according to a preset function. Functions 1 to 5 from Examples 1 to 3 can be used, and will not be described further in this example.

[0482] Example 4: The UE uses a preset function to determine the target frequency domain location.

[0483] In this embodiment, the UE does not need to calculate the first / second frequency domain position, nor does it need to compare the first / second / third frequency domain position with the UL subband frequency domain range. The target frequency domain position is determined directly based on the calculation method of any one of the preset functions in Embodiments 1 to 3. The target frequency domain position can be the start or end position of the RO resource on the SBFD DL symbol. Further details are omitted in this embodiment.
