[0107] FIG1 is a schematic diagram illustrating the architecture of a communication system according to an embodiment of the present disclosure. As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 .

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0115] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 .

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0117] In an embodiment of the present disclosure, . Figure 1B shows a schematic diagram of a RACH-less cell switch process. Referring to Figure 1B, the terminal pre-configuration information, for example, the access network device 102 sends information for configuring resources to the terminal 101, such as the access network device 102 sends a radio resource control (RRC) message to the terminal 101 to perform resource configuration of the candidate cell. For example, configure CG PUSCH time-frequency resources (Configured grant PUSCH, CGO). The terminal 101 reports the L1 measurement report (also known as the beam measurement result) to the source cell. The serving cell decides whether to perform cell switching based on the L1 measurement report / according to the measurement results of each beam. In the case of determining to perform cell switching, the target cell for cell switching is selected from the candidate cells. The source cell sends a cell switching signaling (cell switch command) to the terminal. After receiving the cell switch command, the terminal does not need to access the target cell through the random access process (Random Access Channel less, RACH). Instead, it sends information to the target cell to confirm that the terminal device has accessed the target cell. This can also be understood as the terminal confirming access to the target cell. For example, the terminal sends specific "first UL data" to the target cell to confirm user access, such as the terminal sending a Radio Resource Control Reconfiguration Complete (RRCReconfigurationComplete) message.

[0118] In the embodiment of the present disclosure, the information used to configure resources of the candidate cell is referred to as first information.

[0119] In the embodiment of the present disclosure, the information used by the target cell to determine user access / terminal confirmation of access to the target cell is referred to as second information.

[0120] In one implementation of the embodiment of the present disclosure, the CGO configured by the first information is determined, but when the CGO information changes, how the terminal determines the CGO for sending the second information is a problem that needs to be solved. For example, in some embodiments, when the terminal sends data to the target cell (cell) for the first time to the network device, that is, a confirmation or access message, the initial transmission may fail. At this time, the user can try to resend the access message. When retransmitting, the user can reselect the transmission beam with the target cell. . That is, when retransmitting, the user can reselect the beam (beam), and for this purpose, it is necessary to consider configuring different CG PUSCH time-frequency resources (hereinafter also referred to as CGO) and different beams, so as to perform beam pairing between the user and the network (also referred to as beam pairing between the terminal and the access network device) through this mapping method. In order to enable the user and the target cell to realize beam configuration, consider configuring different CG PUSCH time-frequency resources (CGO) and different beams. By sending a confirmation message on different CGOs, the target cell is implicitly informed of the transmission beam selected by the user

[0121] In view of this, the embodiment of the present disclosure provides a design problem of CG PUSCH for sending the second information for accessing the target cell, including the configuration of time-frequency resources, and the design of the mapping relationship between different beams. The design of CG PUSCH for sending the second information for accessing the target cell provided by the embodiment of the present disclosure can also be understood as a method for resource determination. The embodiment of the present disclosure provides a resource determination method for sending the second information to the target cell during the cell switching process to access the target cell and complete the cell switching.

[0122] FIG2A is an interactive diagram of a resource determination method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a resource determination method, which includes:

[0123] Step S2101: The serving cell sends first information to the terminal.

[0124] It should be noted that the serving cell sending the first information to the terminal can be understood as the network device (such as access network device) to which the serving cell belongs sending the first information to the terminal.

[0125] It can be understood that the terminal receiving the first information sent by the serving cell can be understood as the terminal receiving the first information sent by a network device (such as an access network device) to which the serving cell belongs.

[0126] In some embodiments, the serving cell sending the first information can be understood as the access network device to which the serving cell belongs sending the first information.

[0127] In some embodiments, the terminal receives first information.

[0128] In some embodiments, the first information is used to configure resource information. Optionally, the first information is used to configure time-frequency resources of a non-scheduled physical uplink shared channel (Configured Grant PUSCH, CGO). The time-frequency resources of the non-scheduled physical uplink shared channel may also be referred to as a CG PUSCH transmission opportunity / reception opportunity (CG PUSCH Occasion, CGO).

[0129] In some embodiments, the first information is used to configure resource information of a cell. The cell may be a candidate cell or a source cell.

[0130] In some embodiments, the first information is used to configure a CGO of a candidate cell, wherein the number of the candidate cells is one or more.

[0131] In some embodiments, the first information is used to configure a CGO for each of the one or more candidate cells. Optionally, the CGO for the candidate cell is referred to as a first CGO. There is a one-to-one correspondence between the candidate cell and the first CGO.

[0132] In some embodiments, the number of the first CGOs is one or more, wherein the number of the first CGOs corresponds to the number of the candidate cells. For example, one candidate cell corresponds to one first CGO.

[0133] In some embodiments, the name of the first information is not limited, and it can be, for example, "pre-configuration information", "configuration information", etc.

[0134] In some embodiments, the first information includes RRC signaling, or may be other information used to configure CGO for the terminal.

[0135] In some embodiments, the first information includes at least one of the following: time-frequency resource configuration information of the CGO, and a mapping relationship between the CGO and the beam.

[0136] In some embodiments, the first information is used to configure the time-frequency resource configuration information of the CGO of the cell and the mapping relationship between the CGO and the beam. The cell can be each candidate cell among one or more candidate cells. It is understandable that the cell can also be a target cell, which is a target cell selected from one or more candidate cells for handover.

[0137] In some embodiments, the first information includes at least one of the following: time-frequency resource configuration information of the CGO of one or more candidate cells, and a mapping relationship between the first CGO of one or more candidate cells and the beam and SSB index.

[0138] In some embodiments, the first information includes time-frequency resource configuration information of the CGO. The first information including the time-frequency resource configuration information of the CGO can be understood as a configuration method of the CGO.

[0139] In some embodiments, the time-frequency resource configuration information of the CGO includes at least one of the following:

[0140] CG PUSCH configuration information set.

[0141] In some embodiments, the configuration information set of the CG PUSCH includes one or more configuration information, and each of the one or more configuration information configures a CGO.

[0142] In some embodiments, the configuration information of CG PUSCH may be referred to as CG PUSCH configuration, or as resource configuration of CG PUSCH, or as configuration information.

[0143] In some embodiments, the configuration information set of the CG PUSCH can be understood as a CG PUSCH configuration list (CG PUSCH configuration list), which includes multiple CG PUSCH configurations.

[0144] In some embodiments, one or more configuration information includes time-frequency resource configuration. The time-frequency resource configuration includes time domain resource configuration. Alternatively, the time-frequency resource configuration includes frequency domain resource configuration. Alternatively, the time-frequency resource configuration includes both time domain resource configuration and frequency domain resource configuration.

[0145] In some embodiments, each of the one or more configuration information has a corresponding relationship with the candidate cell. For example, candidate cell A corresponds to one or more configuration information A, and candidate cell B corresponds to one or more configuration information B.

[0146] In some embodiments, the configuration information may be understood as configuration information of the first CGO. Optionally, the candidate cell A corresponds to one or more CGOAs, and the candidate cell B corresponds to one or more CGOBs.

[0147] A CGO configuration and its repetition number.

[0148] In some embodiments, the number of repetitions includes at least one of a first number of repetitions and a second number of repetitions. Optionally, the first number of repetitions represents the number of repetitions of a CGO in the time domain. Optionally, the second number of repetitions represents the number of repetitions of a CGO in the frequency domain.

[0149] In some embodiments, the time-frequency resource configuration information of the CGO includes the time-frequency resource configuration and the number of repetitions. Among them, the second information, such as the content of the first UL data transmission, is basically fixed, and there is no need to allocate time-frequency resources separately for each possible CGO. Therefore, different CGOs have the same time-frequency resource block size, which can meet the transmission of the first UL data. To this end, the time domain repetition number and / or the frequency domain repetition number can be introduced into the time-frequency resource configuration information of the CGO, and the repetition number indicates the number of times the time-frequency resource block of the CG PUSCH is repeated in the time domain and / or the frequency domain.

[0150] In some embodiments, the time-frequency resource configuration information of the CGO includes the number of repetitions of a CGO in the time domain. The number of repetitions of a CGO in the time domain can be understood as the number of repetitions of CGOs with the same time-frequency resource block size in the time domain. Figure 2B shows a schematic diagram of a CGO time-frequency resource configuration with a number of repetitions configured in the time domain. As shown in Figure 2B, the number of repetitions configured in the time domain is 4, and CGO1 configured at time slot (slot) 1, CGO2 configured at slot 2, CGO3 configured at slot 3, and CGO4 configured at slot 4 have the same time-frequency resource block size.

[0151] In some embodiments, when a CGO is repeated in the time domain according to a first repetition number, at least one of the following is satisfied: the repeated CGO is allowed to be located in the same time unit; or the repeated CGO is not allowed to be located in the same time unit.

[0152] In some embodiments, the time unit may be at least one of a slot, a subslot, a frame, a symbol, and the like.

[0153] In some embodiments, repeated CGOs are not allowed to be in the same time unit. For example, a time unit includes a slot. The number of repetitions configured in the time-frequency resource configuration information of the CGO is for repetitions in different slots (inter-slot repetition). For example, repetition only considers inter-slot repetitions as shown in Figure 2B.

[0154] In some embodiments, repeated CGOs are allowed to be in the same time unit. Optionally, when a CGO is repeated in the time domain according to a first repetition number, it can be repeated in the same time unit or in different time units. For example, the time unit is a slot. When a CGO is repeated in the time domain according to the first repetition number, both intra-slot repetition and inter-slot repetition are considered.

[0155] In some embodiments, repeated CGOs are allowed to be in the same time unit. When a CGO is repeated in the time domain according to the first number of repetitions, when it is repeated in the same time unit, a parameter indicating whether the same time unit is allowed to be repeated can be introduced. Optionally, consider introducing an interval parameter for intra-slot repetition, which will be referred to as the first parameter later. The first parameter K is used to determine whether the interval between different CGOs when the same time unit is repeated is allowed. In one example, if the first parameter K is not configured, that is, the parameter K is missing, it is considered that the configuration of repeating the same time unit is not allowed, for example, intra-slot repetition is not allowed. On the other hand, if the first parameter K is configured, it means that the configuration of repeating the same time unit is allowed, and the interval of CGOs in the same time unit is K.

[0156] In some embodiments, the value of the first parameter K is the time interval of repetition. The value unit of K is smaller than the unit of time unit. For example, the time unit is slot, and the unit of K can be symbol. For example, K = 0, 1, ..., N symbol (s). Or other indicative parameters. Figure 2C shows a schematic diagram of CGO time-frequency resource configuration with the number of repetitions configured in the time domain. As shown in Figure 2C, the number of repetitions configured in the time domain is 4, K = 2. Slot1 allows CGO1 and CGO2 to be configured in the same time unit. The interval between CGO1 and CGO2 is K = 2 symbols. Slot2 allows CGO3 and CGO4 to be configured in the same time unit, and the interval between CGO3 and CGO4 is K = 2 symbols. CGO1, CGO2, CGO3, and CGO4 have the same time-frequency resource block size.

[0157] In some embodiments, the first parameter K may be carried in the first information, for example, in RRC signaling.

[0158] In some embodiments, the first information includes a first parameter, and the first parameter represents the interval between repeated CGOs within the same time unit.

[0159] In some embodiments, the first parameter is not included in the first information, and repeated CGOs are not allowed to be located in the same time unit, that is, repeated configuration of the same time unit is not allowed.

[0160] In some embodiments, the time-frequency resource configuration information of the CGO includes a CGO configuration parameter and its number of repetitions in the frequency domain. The number of repetitions of a CGO in the frequency domain can be understood as the number of repetitions of CGOs with the same time-frequency resource configuration. That is, the number of repetitions of CGOs with the same time-frequency resource block size in the frequency domain. Figure 2D shows a schematic diagram of a CGO time-frequency resource configuration with a number of repetitions configured in the frequency domain. As shown in Figure 2D, the number of repetitions configured in the frequency domain is 2, and CGO1 and CGO2 are configured in different frequency domains of slot 1. CGO1 and CGO2 have the same time-frequency resource block size.

[0161] In some embodiments, the time-frequency resource configuration information of the CGO includes a CGO configuration parameter and its number of repetitions in the frequency domain and a number of repetitions of the CGO in the time domain.

[0162] Time-frequency resource block information and CGO quantity information.

[0163] In some embodiments, time-frequency resources of a certain size are configured, and the number of CGOs is configured so that the time-frequency resources of each CGO are allocated according to the number of CGOs in the configured time-frequency resources.

[0164] In some embodiments, the time-frequency resource block information includes at least one of time domain resource block information and frequency domain resource block information. Optionally, the time domain resource block information is used to indicate the total time domain resources occupied by one or more first CGOs within a first time domain resource range. Optionally, the frequency domain resource block information is used to indicate the total frequency domain resources occupied by the first CGO within the first frequency domain resource range.

[0165] In some embodiments, the CGO quantity includes at least one of a first quantity and a second quantity.

[0166] In some embodiments, the time-frequency resource block information includes time domain resource block information, and the number of CGOs includes a first number. The time domain resource block information is used to indicate the total time domain resources occupied by the first number of CGOs within the first time domain resource range, such as the number of occupied time units, such as the number of slots.

[0167] In some embodiments, the time domain resource block information includes at least one of the following: the period of CG PUSCH, the time domain offset (offset), the total number of time units, and the number of CGOs contained in each time unit. Optionally, the time-frequency resource configuration information of CGO includes time domain resource configuration information: the period and offset of CG PUSCH determine the time domain absolute position of the resource. The number of time units, such as the number of time slots (Number of slots), and the number of CGOs included in each time unit (number of CGO per slot) determine the number of slots occupied by the time domain resource and the number of CGOs in each slot. Among them, the period and offset of CG PUSCH determine the time domain absolute position of the resource, which can be understood as the starting position. With this starting position, CGOs are allocated within the specified resource block (first time domain resource range) according to the Number of slots and the number of CGOs per slot.

[0168] In some embodiments, the number of CGOs contained in each time unit can be an integer N, or a fraction, such as 1 / 2, which means that one CGO occupies two slots.

[0169] In some embodiments, the time-frequency resource block information includes frequency domain resource block information, and the number of CGOs includes a second number. The frequency domain resource block information is used to indicate the total frequency domain resources occupied by the second number of CGOs within the first frequency domain resource range.

[0170] In some embodiments, the frequency domain resource block information includes at least one of the following: a physical resource block (PRB) offset of the starting position of the frequency domain resource, a first frequency domain resource range, and a number of CGOs in the first frequency domain resource through frequency division multiplexing.

[0171] In some embodiments, the first frequency domain resource range may be a default value, such as the entire bandwidth part (Bandwidth Part BWP).

[0172] In some embodiments, the time domain resource block information includes at least one of the following: a PRB offset for the frequency domain resource; the allocated frequency domain resource (which may default to the entire BWP); and the number of CGOs multiplexed by frequency division multiplexing in the frequency domain resource. Optionally, the PRB offset is added to the starting position, and the CGOs are allocated within the entire BWP according to the number of CGOs multiplexed by N frequency division multiplexing.

[0173] In some embodiments, the first information includes a mapping relationship between the CGO and the beam of one or more candidate cells.

[0174] In some embodiments, a beam corresponds to a synchronization signal block (Synchronization Signal and PBCH block, SSB) index. Configuring the mapping relationship between a CGO and a beam may be configuring the mapping relationship between a CGO and an SSB index. Optionally, an SSB is also referred to as a synchronization signal / physical broadcast channel signal block.

[0175] In some embodiments, the mapping relationship between the CGO and the beam is determined using at least one of the following methods:

[0176] A. The first mapping method maps the SSB index to the CGO in the order of the CGO time domain index and the CGO frequency domain index.

[0177] In some embodiments, the CGO frequency domain index is mapped first, and then the time domain index is mapped. For example, the CGO is mapped to the SSB index corresponding to the beam in ascending order of the frequency domain index in the first time domain. After the mapping of the frequency domain index in the first time domain is completed, the CGO is mapped to the SSB index corresponding to the beam in ascending order of the frequency domain index in the second time domain. Figure 2E shows a schematic diagram of mapping the SSB index to the CGO according to the order of the CGO time domain index and the CGO frequency domain index. Referring to Figure 2E, CGO1 and CGO2 are first mapped to the SSB index in ascending order of the frequency domain index in slot 1. Then, CGO3 and CGO4 are mapped to the SSB index in ascending order of the frequency domain index in slot 2 in ascending order of the time domain index. Based on the above method, CGO5 and CGO6 are mapped to the SSB index in ascending order of the frequency domain index in slot 3. CGO7 and CGO8 are mapped to the SSB index in ascending order of the frequency domain index in slot 4.

[0178] In some embodiments, the CGO time domain index is mapped first, and then the frequency domain index is mapped. For example, the CGO is mapped to the SSB index corresponding to the beam in ascending order of the time domain index in the first frequency domain. After the mapping of the time domain index in the first frequency domain is completed, the CGO is mapped to the SSB index corresponding to the beam in ascending order of the time domain index in the second frequency domain.

[0179] In some embodiments, when the SSB index is mapped to the CGO, one CGO corresponds to one SSB index.

[0180] In some embodiments, when the SSB index is mapped to the CGO, one CGO corresponds to multiple SSB indexes. At this time, the network can be informed through the third information which SSB index is specifically selected among the multiple SSB indexes corresponding to the CGO.

[0181] In some embodiments, an SSB index is mapped to the CGO in the order of the CGO time domain index and the CGO frequency domain index to complete the mapping of the SSB index to the CGO. In response to the completion of the mapping of the SSB index to the CGO, there is an SSB index that is not mapped to the CGO. The SSB index that is not mapped to the CGO is mapped to other CGOs in the mapping period in sequence according to the first mapping method. The mapping period includes N CGO periods, the other CGOs are CGOs that do not map the SSB index, and the completed mapping is the mapping between the completed SSB index and the CGO. Figure 2F shows a schematic diagram of mapping the SSB index to the CGO in the order of the CGO time domain index and the CGO frequency domain index. As shown in Figure 2F, after the mapping of the SSB index to the CGO is completed, for example, after the mapping method in Figure 2E is mapped, CGO8 and CGO9 that do not have the SSB index mapping, such as the CGO at slot M+1, will not be used for the transmission of the access message. Continue to map the SSB index to CGO8 and CGO9 within the mapping period.

[0182] B. The second mapping method maps the SSB index to the CGO in the order of DMRS code division multiplexing (CDM) group index, demodulation reference signal (DMRS) port number, DMRS sequence number, CGO time domain index, and CGO frequency domain index.

[0183] In some embodiments, the ascending order of CDM groups is prioritized, followed by the ascending order of DMRS ports, and finally the ascending order of DMRS sequences.

[0184] In some embodiments, the SSB index is mapped to the CGO in the following manner according to the order of DMRS code division multiplexing group index, DMRS port number, DMRS sequence number, CGO time domain index, and CGO frequency domain index:

[0185] 1. Map the CGO and the SSB index corresponding to the beam in ascending order of the code division multiplexing group index.

[0186] 2. After the mapping of the code division multiplexing group index is completed, the CGO and the SSB index corresponding to the beam are mapped in ascending order of the DMRS port number.

[0187] 3. After the mapping of the DMRS port number is completed, map the CGO and the SSB index corresponding to the beam in ascending order of the serial number.

[0188] 4. After the mapping of the serial number is completed, map the CGO and the SSB index corresponding to the beam in ascending order of the CGO frequency domain index.

[0189] 5. After the mapping of the CGO frequency domain index is completed, map the CGO and the SSB index corresponding to the beam in ascending order of the CGO time domain index.

[0190] In some embodiments, when the SSB index is mapped to the CGO, one CGO corresponds to one SSB index.

[0191] In some embodiments, the SSB index mapped to the CGO is multiple SSB indexes. One CGO corresponds to multiple SSB indexes.

[0192] In some embodiments, the SSB index is mapped to the CGO in the order of the DMRS code division multiplexing group index, the DMRS port number, the DMRS sequence number, the CGO time domain index, and the CGO frequency domain index to complete the mapping of the SSB index to the CGO. In response to the completion of the mapping of the SSB index to the CGO in accordance with the second mapping method, there is an SSB index that is not mapped to the CGO. According to the second mapping method, the SSB index that is not mapped to the CGO is sequentially mapped to other CGOs in the mapping period. Among them, the mapping period includes N CGO periods, and the other CGOs are CGOs that do not map the SSB index, and the mapping is completed as the mapping between the completed SSB index and the CGO. For example, as shown in Figure 2F, after the mapping of the SSB index to the CGO is completed in accordance with the second mapping method, CGO8 and CGO9 that do not have the SSB index mapping, such as the CGO at slot M+1, will not be used for the transmission of the access message. Continue to map the SSB index to CGO8 and CGO9 within the mapping period.

[0193] C. The third mapping method maps the SSB index to the CGO according to the mapping relationship of the network configuration.

[0194] In some embodiments, the mapping relationship represents a correspondence between a CGO and one or more SSB indexes.

[0195] In some embodiments, the time-frequency resource configuration information of the first CGO includes a configuration information set of a CG PUSCH. The configuration information set of the CG PUSCH includes one or more configuration information, each of the one or more configuration information configures a CGO and an SSB index corresponding to the CGO.

[0196] Method 1: Only one SSB index corresponds to multiple CGOs. In this case, only one SSB index can be configured in each configuration.

[0197] Method 2: Supports the case where one or more SSB indices correspond to multiple CGOs. In this case, one or more SSB indices can be configured in each configuration. In this case, in order to further distinguish the multiple SSB indices corresponding to a CGO, DMRS resources can be configured to distinguish each SSB index, such as CDM group, DMRS port, or DMRS sequence.

[0198] For example, for the second method: one or more SSB indexes correspond to multiple CGOs, in addition to configuring the SSB index corresponding to the CGO in the time-frequency resource configuration information of the CGO, it is necessary to further configure other resources corresponding to the SSB index. Other resources can be, for example, DMRS CDM group index, DMRS port index, etc., which are used to further distinguish specific SSB indexes.

[0369] Step S5101: The serving cell sends first information to the terminal.

[0373] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0374] This embodiment also provides a resource determination method, which is used to send a confirmation message to a target cell during a handover process to access the target cell and complete the handover.

[0375] In some embodiments, the resource determination method includes the following: a configuration method of a schedulable Grant (CG) PUSCH time-frequency resource (CGO) of a target / candidate cell, and a design of a mapping relationship between the CG PUSCH time-frequency resource (CGO) and the beam.

[0376] In some embodiments, the CGO configuration method of the target / candidate cell includes at least one of the following:

[0377] -A) In the pre-configuration information of each candidate cell, a CG PUSCH configuration list is configured, which includes multiple CG PUSCH configurations. Each configuration information includes a time-frequency resource configuration.

[0378] -B) Introducing the repetition number in the CG PUSCH resource configuration.

[0379] For example, please refer to the embodiment of FIG2B and the related description of FIG2D , which will not be described in detail here.

[0380] -C) specifies a resource and the number of CGOs.

[0381] In some embodiments, with respect to -B), at least one of the following conditions is included:

[0382] -a) Only inter-slot repetition is considered, that is, only the inter-slot repetition as shown in FIG2B is considered.

[0383] -b) Consider both intra-slot repetition and inter-slot repetition, as shown in Figure 3. To this end, a parameter can be introduced to determine whether intra-slot repetition is performed. For example, a parameter K can be introduced to indicate the interval of intra-slot repetition. If K is not configured (i.e., missing), intra-slot repetition is considered not allowed. If K is configured, it is allowed, and its specific value is the repetition interval, such as K = 0, 1, ..., N symbols (symbol(s)). Or other indicating parameters can be considered.

[0384] For example, please refer to the relevant description of the embodiment in FIG2C , which will not be described in detail here.

[0385] In some embodiments, for -C), at least one of the following conditions is included:

[0386] a) Time Domain Resources: The CG PUSCH period and offset determine the absolute time domain location of the resources. The number of slots and the number of CGOs per slot are defined to determine the number of slots occupied by time domain resources and the number of CGOs per slot.

[0387] -b) Frequency domain resources: PRB offset of frequency domain resources; allocated frequency domain resources (can default to the entire BWP); number of CGOs in the frequency domain resources through frequency division multiplexing.

[0388] In some embodiments, the mapping relationship between CG PUSCH time-frequency resources (CGO) and beams is designed to include at least one of the following:

[0389] 1) Mapping is performed based on the CGO frequency domain index and time domain index, as shown in the figure below. The case where one CGO corresponds to multiple SSB indices is not considered. If there are many SSBs, the mapping period can be set to N times the CGO period.

[0390] 2) The correspondence with SSB can be designed according to DMRS index and time-frequency resources, just like in SDT.

[0391] 3) is the same as 1), mapping is performed by first CGO frequency domain index and then time domain index, and one CGO is allowed to correspond to multiple SSB indices.

[0392] 4) Network configuration mapping relationship.

[0393] In some embodiments, for the exemplary description of 1), please refer to Figure 2E and the description of related embodiments, which will not be repeated here.

[0394] In some embodiments, for 2), a CDM group index mapping is added, that is, the ascending order of CDM groups is given priority, followed by the ascending order of DMRS ports, and finally the ascending order of sequences.

[0395] It is understandable that the detection of CDM groups is simpler, as it only requires detecting the received power of the corresponding RE. If the RO needs to correspond to more SSBs, consider using port and sequence to distinguish them.

[0396] It can be understood that, for 3) when a CGO corresponds to multiple SSB indexes, special information can be directly introduced in the first UL data to inform the network which of the multiple SSBs it corresponds to.

[0397] In some embodiments, the CG PUSCH resource is configured in accordance with Option 1, and in each configuration, the mapped SSB index needs to be specified.

[0398] In some embodiments, the mapped SSB index is specified based on at least one of the following:

[0399] Only one SSB index corresponds to multiple CGOs; only one SSB index corresponds to multiple CGOs. In this case, in addition to configuring the SSB index corresponding to the CGO, the CGO configuration also requires further configuration of other resources corresponding to the SSB index, such as DMRS CDM group index, DMRS port index, etc., to further distinguish the specific SSB index.
