[0107] In the embodiment of the present disclosure, the information used to configure resources of the candidate cell is referred to as second information.

[0108] 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 third information.

[0109] In one embodiment of the present disclosure, the resource used to send the third information is the target cell's Configured Grant Physical Uplink Shared Channel (CG PUSCH) resource, which is a Type 1 CG PUSCH. Once configured, the Type 1 CG PUSCH resource takes effect, causing the resource to remain occupied. Reducing the resource overhead used to send access target messages is a challenge.

[0110] In view of this, an embodiment of the present disclosure provides a design problem of a CG PUSCH for sending third information of accessing a target cell, including introducing a new CG PUSCH type, or designing a CG PUSCH time-frequency resource configuration (CG PUSCH Occasion, mapping relationship between CG O and different beams).

[0111] The design of the CG PUSCH for sending the third information for accessing the target cell provided in the embodiment of the present disclosure can also be understood as a method for determining resources.

[0113] Among them, the new CG PUSCH type can be understood as CG PUSCH resource configuration, and then CG PUSCH resource activation.

[0114] In one example, the new CG PUSCH type is determined based on the first information. The first information is used to trigger user handover to the target cell and to activate the CG PUSCH resources of the target cell. In some embodiments, the activated CG PUSCH resources are used by the terminal to send third information to the target cell.

[0115] In some embodiments, the resource determination method includes: designing a mapping relationship between CGO and beam, and determining CG PUSCH resources.

[0116] In some embodiments, the mapping relationship between CGO and beam is designed to include: there is a corresponding relationship between the CGO corresponding to the CG PUSCH resource and the SSB index.

[0117] In one example, the corresponding relationship satisfies: one CGO corresponds to multiple synchronization signal block SSB indexes.

[0118] In some embodiments, the correspondence is configured as follows: the number of SSB indexes configured for each CGO is greater than 1.

[0119] In some embodiments, the number of SSB indexes configured for each CGO is greater than 1, and is configured in at least one of the following ways: configuring the SSB index according to the DMRS group; and the third information indicates the number of SSB indexes.

[0159] Step S2106: The serving cell sends the first information.

[0160] 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.

[0161] 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.

[0162] In some embodiments, the terminal receives first information.

[0163] In some embodiments, the first information is used to trigger user handover to the target cell and to activate the CG PUSCH resources of the target cell.

[0164] In some embodiments, the activated CG PUSCH resources are used by the terminal to send third information to the target cell.

[0165] In some embodiments, the third information is used to instruct the target cell terminal to switch to the target cell.

[0166] In some embodiments, the first information includes at least target cell information and indication information indicating whether to activate the CG PUSCH of the target cell.

[0167] In some embodiments, the first information includes at least one of the following information: target cell information; indication information indicating whether to activate the CG PUSCH of the target cell; and CG PUSCH time-frequency resource configuration information.

[0168] In some embodiments, the CG PUSCH time-frequency resource configuration information includes a first repetition number and a second repetition number. Optionally, the first repetition number indicates the number of repetitions of the scheduling-free physical uplink shared channel time-frequency resource CGO in the time domain. Optionally, the second repetition number indicates the number of repetitions of CGO in the frequency domain.

[0169] In some embodiments, the first repetition number can be understood as the number of repetitions of CGOs with the same time-frequency resource block size in the time domain. Figure 2C shows a schematic diagram of a CGO time-frequency resource configuration with a repetition number configured in the time domain. As shown in Figure 2C, the number of repetitions configured in the time domain is 4, and CGO1 configured in time slot 1, CGO2 configured in slot 2, CGO3 configured in slot 3, and CGO4 configured in slot 4 have the same time-frequency resource block size.

[0170] In some embodiments, the second repetition number can be understood as the number of repetitions of a CGO with the same time-frequency resource configuration. That is, the number of repetitions of a CGO 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 repetition number configured in the frequency domain. As shown in Figure 2D, the repetition number configured in the frequency domain is 2, and CGO1 and CGO2 are configured in different frequency domains in slot 1. CGO1 and CGO2 have the same time-frequency resource block size.

[0175] 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.

[0176] In some embodiments, the time-frequency resource block information includes frequency domain resource block information, and the number of CGOs includes a second number.

Among them, the absolute time domain position of the resource determined by the period and offset of the CG PUSCH can be understood as the starting position. At 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.

[0180] 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.

[0181] In some embodiments, the frequency domain resource length 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 that are frequency-division multiplexed in the first 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.

[0184] In some embodiments, there is a correspondence between the CGO corresponding to the CG PUSCH resource and the synchronization signal block SSB index.

[0185] In some embodiments, the correspondence between CGO and SSB index satisfies: one CGO corresponds to multiple synchronization signal block SSB indexes. It is understandable that when the SSB index is mapped to CGO, one CGO corresponds to multiple SSB indexes.

[0186] In some embodiments, the correspondence is configured as follows: the number of SSB indexes configured for each CGO is greater than 1.

[0187] In some embodiments, the number of SSB indexes configured for each CGO is greater than 1, and is configured in at least one of the following ways: configuring the SSB index according to the DMRS group; and the third information indicates the number of SSB indexes.

[0189] In one embodiment, the third information indicates the number of SSB indexes, which can be understood as the terminal informing the network through the third information which SSB index among the multiple SSB indexes corresponding to the CGO is specifically selected.

[0190] In one embodiment, the first information is a cell switching instruction sent by the serving cell to the terminal.

[0197] In some embodiments, the third information is sent to the target cell when the terminal receives the first information.

[0198] In some embodiments, the third information is sent to the target cell when the serving cell instructs the terminal to perform cell switching.

[0199] In some embodiments, the third information is used to indicate the SSB index.

[0200] In some embodiments, the name of the third information is not limited, and it can be, for example, "first uplink data", "confirmation message", "confirmation switching message", etc.

[0361] In some embodiments, a new CG PUSCH type is introduced, including at least one of the following:

[0362] -A) Configure CG PUSCH resources through RRC and activate them through a cell switch command. When the user switches to the target cell, the target cell deactivates the CG PUSCH.

[0369] Optionally, for at least one of -A) or -B), to ensure that the target cell does not allocate time and frequency resources to other users during user switching, it may be considered to send a request message to the target cell before the cell switch, and then send a cell switch command to the user after receiving a confirmation message.

[0370] 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:

[0371] 1) Configure SSB per CGO to a value greater than 1
