[0039] In order to facilitate a better understanding of the embodiments of the present application, the following technical points are first introduced below.

[0040] 1. Cell switching (L1 / L2 Triggered Mobility, LTM) switching process based on Layer 1 (L1) / Layer 2 (L2)

[0041] like Figure 2 As mentioned above, the LTM switching process is as follows:

[0042] (1) Radio Resource Control (RRC) pre-configuration: The terminal receives the pre-configuration information of the candidate cells sent by the network side;

[0043] (2) Measurement reporting: The terminal obtains L1 measurement results by measuring the reference signals (RS) (such as synchronization signal blocks (SSB)) of the current serving cell and neighboring cells and reports them;

[0044] (3) Handover command: The terminal receives the cell handover command sent by the network side and applies the RRC configuration information of the target cell;

[0045] (4) Downlink synchronization and automatic gain control (AGC) adjustment: The terminal decodes the demodulation reference signal (DMRS) and PBCH of the physical broadcast channel (PBCH) according to the first SSB of the target cell after RRC reconfiguration, obtains the system frame number, half-frame indicator and SSB index, performs downlink synchronization at the frame level, time slot level and symbol level, and adjusts the automatic gain control (AGC) parameters according to the received power of the SSB;

[0046] (5) Uplink synchronization: After downlink synchronization, the terminal performs uplink synchronization through the Random Access Channel (RACH) until it receives the Random Access Response (RAR) and obtains the Timing Advance (TA). The uplink synchronization is completed.

[0047] Among them, it is currently agreed that the LTM switching signaling at least includes the configuration information index of the target cell and the indication information of the uplink beam or the downlink beam.

[0048] In order to reduce the LTM switching interruption time caused by uplink synchronization (random access process), a Rach-less switching solution is proposed in the related art, where Rach-less includes the following two cases:

[0049] RACH early: the candidate cell allocates non-contention random access (CFRA) resources to the user equipment (UE). The network executes RACH in order through the physical downlink control channel (PDCCH) before the handover is initiated to perform uplink synchronization in advance.

[0050] Rach-less in LTE: The candidate cell has a small coverage area and the TA value is 0; or the candidate cell and the source cell belong to the same TAG, that is, the TA value is the same.

[0051] For the Rach-less handover solution, it has been agreed in LTM that the UE can inform the target cell of its handover in the following two ways:

[0052] Method 1: Dynamic Grant

[0053] Dynamic Grant: After the source cell sends a cell switching command to the UE, it informs the target cell of the UE identity and the beam information that the UE will use through the high-level interface. The target cell then starts to use the corresponding beam information to send the UE's corresponding C-RNTI scrambled PDCCH (DCI) for uplink data scheduling. When the UE receives the corresponding DCI, it sends the switching completion information on the uplink resources indicated in the DCI. When the network successfully receives the switching completion information on the corresponding uplink resources, it can be determined that the corresponding UE has completed the switching.

[0054] Method 2: Configured Grant

[0055] Configured Grant: After the source cell sends a cell handover command to the UE, it no longer informs the target cell of the UE's handover behavior. After receiving the cell handover command, the UE starts to send handover completion information on the CG resources configured for it by the network side. After the network detects the handover completion information on the CG resources, it can determine that the corresponding UE has completed the handover.

[0056] 2. CG transmission

[0057] In NR, in order to meet the needs of low-latency services or periodic services, NR supports the uplink semi-static configured grant transmission method to reduce the signaling interaction process and ensure low latency requirements. The resources for Configured grant transmission can be semi-statically configured through RRC signaling. When service data arrives, the UE can send data on the uplink channel (such as PUSCH) of the configured grant. NR supports two types of CG PUSCH: type 1 and type 2. Type 1 CG PUSCH means that the UE can transmit data on the CG PUSCH after the RRC parameters are configured. Type 2 CGPUSCH means that the UE can transmit data on the CG PUSCH after the RRC parameters are configured and the DCI activates the CG PUSCH. The CGPUSCH2 high-level parameter ConfiguredGrantConfig is configured, and it includes the common configuration parameter repetition count, repeated redundancy version, power control parameters (P0-alpha and closed loop), hybrid automatic repeat request (Hybrid Automatic RepeatRequest, HARQ), period, etc.;

[0058] 2.1. Type 1 CG PUSCH

[0059] The ConfiguredGrantConfig corresponding to Type 1 CG PUSCH contains rrc-ConfguredUplinkGrant, which indicates the time-frequency domain resources, modulation and coding scheme (MCS), antenna port, sounding reference signal (SRS) resource indication, demodulation reference signal, precoding matrix indication, path loss reference signal and other uplink transmission parameters required for CG PUSCH. The terminal determines the transmission beam of CG PUSCH according to the SRS resource indication, and determines the transmission power of CG PUSCH according to the path loss reference signal and the power control parameters of the common parameter part. After receiving the RRC signaling indicating Type 1 CG PUSCH, it can start to periodically send CG PUSCH according to the configuration information.

[0060] 2.2 Type 2 CG PUSCH

[0061] There is no rrc-ConfguredUplinkGrant in the ConfiguredGrantConfig corresponding to Type 2 CG PUSCH, and the corresponding uplink transmission required parameters are indicated by the downlink control information (Downlink ControlInformation, DCI). Therefore, after receiving the ConfiguredGrantConfig, the terminal will not perform uplink transmission immediately, but will wait until it receives the DCI indication activation encrypted by the configured scheduling RNTI (Configured Scheduling RNTI, CS-RNTI) before sending. The corresponding Type 2 CG PUSCH's time-frequency domain resources, MCS, antenna port, SRS resource indication, demodulation reference signal, precoding matrix indication, etc. are indicated in the DCI. The path loss reference signal is determined according to the SRS resource indication indicated in the DCI.

[0062] 2.3 CG PUSCH under Rel-17 unified TCI framework

[0063] In order to simplify the beam indication signaling mechanism to reduce signaling overhead, Rel-17 introduced a unified TCI framework, that is, uplink / downlink share one beam. In the connected state and non-switching scenario, the beam of CGPUSCH always changes with the joint TCI (joint TCI) or uplink (UL) TCI indicated by the network, and the transmission power of CGPUSCH is determined according to the joint TCI or UL TCI associated uplink power control parameter ul-powerControl and the path loss reference signal.

[0064] The following, in conjunction with the accompanying drawings, describes in detail the information sending method, device and terminal provided in the embodiments of the present application through some embodiments and their application scenarios.

[0065] See also Figure 3 , Figure 3 is a flow chart of a method for sending information provided by an embodiment of the present application, such as Figure 3 As shown, the information sending method includes the following steps:

The starting frequency point is composed of at least one of a frequency band, a frequency band, a resource block (RB), and a resource element (RE). The occupied bandwidth is Y RBs / RE, and the value of Y is specified by the network configuration or protocol.

[0115] In one implementation, the terminal determines the target configuration authorization resource based on the configuration information of the configuration authorization resource of the target object and the configuration authorization resource indicated by the first indication information. For example, the configuration authorization resource indicated by the first indication information refers to the first time domain resource and the first frequency domain resource, wherein the first time domain resource includes a first time slot offset value and a duration, and the first frequency domain resource includes a first frequency domain offset value and an occupied bandwidth. The terminal determines the absolute time and frequency domain resource starting point of the target object based on the timing information and frequency domain information of the target object, and the target configuration authorization resource can be determined in combination with the configuration authorization resource indicated by the first indication information.

[0116] In one implementation, the terminal determines the target configuration authorization resource based on the configuration information of the configuration authorization resource of the target object and the configuration authorization resource indicated by the first indication information. For example, the configuration authorization resource indicated by the first indication information refers to a configuration authorization resource index, and the target configuration authorization resource can be determined in a configuration authorization resource list according to the configuration authorization resource index, and the configuration authorization resource list is included in the configuration information of the configuration authorization resource of the target object.

[0117] In this implementation, the terminal determines the target configuration authorization resource based on at least one of the configuration information of the configuration authorization resource of the target object and the configuration authorization resource indicated by the first indication information; the terminal sends the second information on the target configuration authorization resource. This can support the terminal to determine the target configuration authorization resource through the configuration authorization resource indicated by the first indication information included in the message for cell switching and the configuration information of the configuration authorization resource of the target object, and send the second information including the indication information indicating the success of the cell switching on the target configuration authorization resource, which can improve the flexibility of information sending.

[0123] The second information may include: identification information of the terminal under the target object. The identification information of the terminal under the target object may be identity information of the terminal under the target cell. For example, the identity information may be a cell radio network temporary identifier (Cell RNTI, C-RNTI). Optionally, when the configuration authorization resource of the target object is dedicated to the terminal, the second information does not include the identification information of the terminal under the target object.

[0124] It should be noted that the second information may include the beam information indicated by the first indication information, so that the network side can determine the beam information of the terminal based on the received second information.

[0125] It should be noted that the second information may include identification information of the terminal under the target object, so that the network side can identify the terminal through the identification information of the terminal under the target object carried in the second information.

[0126] Optionally, the first information includes a power control parameter of the target configured authorized resource, and before the terminal sends the second information on the target configured authorized resource based on the first information, the method further includes:

[0128] The third information includes at least one of the following:

[0129] A power control parameter associated with the beam information indicated by the first indication information;

[0130] The power control parameter in the configuration information of the configuration authorization resource of the target object indicated by the first indication information;

[0131] a power control parameter indicated by second indication information, where the second indication information is carried in a message for cell switching received by the terminal;

[0132] The power control parameters are determined according to the protocol agreed rules.

[0133] The beam information may be an uplink (UL) TCI state. The terminal may determine the power control parameter of the target configuration authorized resource according to the power control parameter associated with the UL TCI state indicated by the first indication information.

[0134] In one implementation, the terminal determines a power control parameter of the target configured authorized resource based on third information, and the target configured authorized resource may be a shared configured authorized resource.

[0135] In one implementation, the terminal may use the power control parameter included in the third information as the power control parameter of the target configuration authorized resource.

[0136] In this implementation, the terminal determines the power control parameters of the target configured authorized resources based on the third information, and the terminal sends the second information on the target configured authorized resources based on the power control parameters of the target configured authorized resources, thereby supporting the terminal to determine the power control parameters of the target configured authorized resources to send the second information when multiple terminals in a cell share the configured authorized resources.

[0137] Optionally, the first information includes a transmission configuration parameter of the target configuration authorization resource, and before the terminal sends the second information on the target configuration authorization resource based on the first information, the method further includes:

[0138] The terminal determines, based on the fourth information, a transmission configuration parameter of the target configuration authorization resource;

[0144] In one implementation, the terminal may use the transmission configuration parameters included in the fourth information as the transmission configuration parameters of the target configuration authorization resource.

[0145] In this implementation, the terminal determines the transmission configuration parameters of the target configuration authorization resources based on the fourth information, and the terminal sends the second information on the target configuration authorization resources based on the transmission configuration parameters of the target configuration authorization resources, thereby supporting the terminal to determine the transmission configuration parameters of the target configuration authorization resources to send the second information when multiple terminals in a cell share the configuration authorization resources.

[0146] Optionally, the first information includes a scrambling code parameter of the target configuration authorized resource, and before the terminal sends the second information on the target configuration authorized resource based on the first information, the method further includes:

[0147] The terminal determines, based on the fifth information, a scrambling code parameter of the target configuration authorization resource;

[0148] The fifth information includes at least one of the following:

[0149] a scrambling code parameter indicated by fourth indication information, the fourth indication information being carried in a message for cell switching received by the terminal, or being carried in a high-layer configuration signaling;

[0150] A first scrambling code parameter, where the first scrambling code parameter is determined by the terminal according to at least one of a time domain resource and a frequency domain resource of the target configuration authorized resource.

[0151] In one implementation, the scrambling code parameter refers to a temporary wireless network identifier of CG transmission in a cell switching scenario, which is used to scramble PUSCH data; optionally, the scrambling code parameter can be calculated based on the time-frequency domain resources of the target configuration authorized resources, and its value range is FFF4-FFFC.

[0152] In one implementation, the terminal determines a scrambling code parameter of the target configured authorized resource based on the fifth information, and the target configured authorized resource may be a shared configured authorized resource.

[0153] In an implementation manner, the terminal may use the scrambling code parameter included in the fifth information as the scrambling code parameter of the target configuration authorization resource.

[0154] In this implementation, the terminal determines the scrambling code parameters of the target configured authorized resources based on the fifth information, and the terminal sends the second information on the target configured authorized resources based on the scrambling code parameters of the target configured authorized resources, thereby supporting the terminal determining the scrambling code parameters of the target configured authorized resources to send the second information when multiple terminals in a cell share the configured authorized resources.

[0155] Optionally, the terminal sends the second information on the target configuration authorization resource based on the first information, including:

[0156] The terminal sends the second information multiple times on the target configuration authorization resource based on the first information and the sixth information; wherein the sixth information is used to indicate the number of times the second information is sent;

[0157] The sixth information is carried in a message for cell switching received by the terminal, or is carried in a high-level configuration signaling.

[0158] The terminal may send the second information multiple times on the target configuration authorized resource according to the number of times the second information is sent indicated by the sixth information. For example, the terminal may send the second information multiple times on the target configuration authorized resource using the same beam according to the number of times the second information is sent indicated by the sixth information, and the beam for sending the second information may cover all beams of the terminal.

[0159] In this implementation, the terminal sends the second information multiple times on the target configuration authorization resource based on the first information and the sixth information, wherein the sixth information is used to indicate the number of times the second information is sent, thereby improving the success rate of the network side receiving the second information.

[0160] Optionally, the beam for sending the second information by the terminal is determined based on the beam information indicated by the first indication information.

[0184] Example 1.3:

[0185] This embodiment provides a method for determining CG resources based on the association between CG PUSCH and beam.

[0186] Example 1.31:

[0187] There is an M1 to N1 association relationship between the SSB set and the CG resource set of the target cell, that is, M1 SSBs in the SSB set can be associated with N1 CG resources.

[0188] Optionally, M1, N1, or the ratio of M1 / N1 is determined according to the network configuration or specified by the protocol (for example, one-to-one mapping of SSB indexes in the SSB set from small to large to CG PUSCH resources in a pre-numbered order).

[0189] For example:

[0190] (1) The UE receives CG resources configured by the network, where the CG resources are associated with the SSB set;

[0191] (2) The UE receives a cell handover command sent by the source cell, including the TCI state;

[0192] (3) The UE determines the QCL sourceRS corresponding to the TCI state, i.e., SSB X, according to the TCI state obtained in step (2);

[0193] (4) The UE determines the CG resource associated with the SSB X, such as CG resource Y, according to the association relationship obtained in step (1), and uses CG resource Y for initial uplink transmission in the target cell.

[0194] Example 1.32:

[0195] There is an M2 to N2 mapping relationship between the CSI-RS set and the CG resource set of the target cell, that is, M2 CSI-RSs in the CSI-RS set can be mapped to N2 CG resources.

[0196] Optionally, M2, N2, or the ratio of M2 / N2 is determined according to the network configuration or specified by the protocol (for example, one-to-one mapping of CSI-RS resource indexes in the CSI-RS set from small to large to CG PUSCH resources in a pre-numbered order).

[0200] (3) The UE determines the QCL sourceRS corresponding to the TCI state, i.e., CSI-RS X, according to the TCI state obtained in step (2);

[0201] (4) The UE determines the CG resource associated with the CSI-RS X, for example, CG resource Y, according to the association relationship obtained in step (1), and uses CG resource Y for initial uplink transmission in the target cell.

[0202] Example 1.33:

[0203] The network configures a TCI state list for the target cell, and there is an M3 to N3 mapping relationship between the TCI state list and the CG resource set of the target cell, that is, M3 TCI state lists in the TCI state list can be mapped to N3 CG resources.

[0204] Optionally, M3, N3, or the ratio of M3 / N3 is determined according to the network configuration or by the protocol (for example, one-to-one mapping of the TCI state index in the TCIstate list from small to large to the PUSCH resources in a pre-numbered order).

[0205] For example:

[0206] (1) The UE receives CG resources configured by the network, where the CG resources are associated with a TCI state set;

[0207] (2) The UE receives a cell handover command sent by the source cell, including TCI state X;

[0208] (3) The UE determines the CG resource associated with the TCI state X, such as CG resource Y, according to the association relationship obtained in step (1), and uses CG resource Y for initial uplink transmission in the target cell.

[0209] Example 1.4:

[0210] This embodiment provides a method for determining the power control parameters of the CG PUSCH of an associated beam.

[0211] The terminal determines the path loss reference signal to determine the transmit power of the target CG PUSCH resource according to at least one of the following:

[0212] The quasi co-located source reference RS corresponding to the TCI state associated with the target CG PUSCH resource;

[0213] the SSB associated with the target CG PUSCH resource;

[0214] The CSI-RS associated with the target CG PUSCH resource.

[0215] Optionally, the terminal may determine which of the above-mentioned methods is used to determine the path loss reference signal according to the conditions described in Embodiment 1.5 and Embodiment 1.6.

[0216] Example 1.5:

[0217] This embodiment determines a path loss reference signal according to the power control parameters configured in the CG configuration information of the target cell to determine the transmission power of the target CG PUSCH resource.

[0218] When the CG configuration information of the associated target cell for cell switching includes power control parameters such as the path loss reference signal identifier corresponding to the CG PUSCH transmission, the basic operating point of the PUSCH transmit power, the PUSCH downlink path loss compensation factor (P0-alpha for short), and the closed-loop power control factor, the terminal determines the transmit power of the target CG resource according to the above power control parameters under any of the following conditions:

[0219] Condition 1: No restrictions;

[0220] Condition 2: The power control parameters such as ul-powerControl-r17 and path loss reference signal identifier in the TCI state indicated in the cell handover command or the TCI-UL-state configuration information are default;

[0221] Condition three: The TCI state or TCI-UL-state configuration information indicated in the cell switching command contains power control parameters such as ul-powerControl-r17 and path loss reference signal identifier, and the network configures or instructs the terminal to use the power control parameters contained in the CG configuration information of the associated target cell for cell switching to send CG PUSCH.

[0222] Example 1.6:

[0223] This embodiment determines a path loss reference signal according to a power control parameter associated with a TCI state or TCI-UL-State indicated in a cell switching command to determine the transmission power of the target CG PUSCH resource.

[0224] When the TCI state or TCI-UL-state configuration information indicated in the cell switching command contains power control parameters such as ul-powerControl-r17 and path loss reference signal identifier, under any of the following conditions, the terminal determines the transmit power of the target CG resource according to the power control parameters such as ul-powerControl-r17 and path loss reference signal identifier in the TCI state or TCI-UL-state configuration information.

[0225] Condition 1: No restrictions;

[0226] Condition 2: When the power control parameters such as the path loss reference signal identifier corresponding to the CG PUSCH transmission, the basic operating point of the PUSCH transmission power, the PUSCH downlink path loss compensation factor (P0-alpha for short), and the closed-loop power control factor described in the CG configuration information of the associated target cell for cell handover are default;

[0227] Condition three: When the CG configuration information of the associated target cell used for cell switching contains power control parameters such as the path loss reference signal identifier corresponding to the CG PUSCH transmission, the basic operating point of the PUSCH transmit power, the PUSCH downlink path loss compensation factor (P0-alpha for short), and the closed-loop power control factor, and the network configures or instructs the terminal to use the power control parameters in the configuration information corresponding to the TCI state or TCI-UL-state indicated in the cell switching command to send CGPUSCH.

[0228] Embodiment 2:

[0229] Embodiment 2 implements the Common CG PUSCH transmission enhancement solution.

[0230] Common CG PUSCH means that the mapping relationship between the beam and the configured authorized resource is 1:M, where M is the number of RSs in the first RS set or the number of TCI states in the TCI state set; in other words, there is no mapping relationship between the beam and the configured authorized resource. For this authorized resource configuration, when the terminal receives a cell switching command, it can select the nearest CG resource and use the beam indicated in the cell switching command to send the second information until the maximum number of CG transmissions is reached or the terminal receives feedback from the network side for the successful receipt of the indication information of the successful cell switching; since Common CG PUSCH transmission has no transmission interval relative to the transmission scheme associated with CG PUSCH and the beam, the delay of the Common CG PUSCH transmission scheme is small, thereby reducing the switching delay. The method for determining the power control parameters corresponding to the second information sent by the terminal on the nearest CG occasion is consistent with embodiments 1.5 and 1.6 in embodiment 1. Since there is no mapping relationship between CG resources and beams, the target cell cannot determine the beam after receiving the CG resources, so the second information needs to include the beam indication information indicated in the cell switching command, that is, the beam information is notified to the target cell through uplink data.

[0231] Embodiment three:

[0232] Embodiment 3 implements a shared CG PUSCH transmission enhancement solution.

[0233] In traditional CG PUSCH transmission, CG PUSCH resources are UE-specific configuration information. In LTM, the CG PUSCH resources of the target cell need to be configured for the terminal. In order to avoid resource collision, the CG PUSCH resources allocated to different terminals in the target cell cannot overlap, and after the CG PUSCH resources are configured in RRC, only specific terminals can send uplink data on the corresponding resources until the RRC parameters are released. Therefore, the use of UE-specific CG PUSCH resource configuration schemes has the problem of uplink resource waste.

[0234] In the related technology, the following solution can be used to solve the problem: introduce a shared CG PUSCH transmission solution, that is, the target cell informs the source cell of its corresponding CG PUSCH configuration information, and the source cell dynamically allocates CG PUSCH resources to the terminal through a cell switching command, thereby solving the problem of uplink resource waste. Since multiple UEs in the target cell share a set of CG PUSCH resources, there are the following three problems:

[0235] (1) Because different UEs have different capabilities and corresponding channel states, the transmission configuration parameters corresponding to CG PUSCH resources need to be further clarified;

[0236] (2) How to implement scrambling of uplink data sent on the shared CG PUSCH;

[0237] (3) After receiving the CG PUSCH, the target cell cannot determine the corresponding UE identity.

[0238] The above-mentioned problems can be solved by Example 3.1, Example 3.2, Example 3.3 and Example 3.4.

[0239] Example 3.1:

[0240] This embodiment provides a method for determining transmission configuration parameters.

[0241] The terminal may determine the transmission configuration parameters of the CG PUSCH according to at least one of the following methods:

[0242] Determined by transmission configuration parameters indicated in cell switching; the transmission configuration parameters include but are not limited to port indication information and transmission precoding matrix identifier and modulation order;

[0243] It is determined by the public transmission configuration parameters configured by the network; optionally, the port indication information and the transmission precoding matrix identifier TPMI can be defaulted (in other words, single-port CG PUSCH uplink transmission is performed), and the modulation order MCS is set to a default value, for example, the lowest value in the MCS table.

[0244] In the related art, CG PUSCH resource configuration and transmission configuration parameters are UE-specific. For the case of shared CG, one method is that all UEs use the same set of transmission configuration parameters to send CG PUSCH. For the shared CG scheme, there is a problem of how to determine the transmission configuration parameters corresponding to the CG PUSCH resources. This embodiment can be used for the shared CG scheme, and can realize the determination of the transmission configuration parameters under the shared CG.

[0245] Example 3.2:

[0246] This embodiment provides a method for generating a scrambling code for a shared CG PUSCH.

[0247] The terminal determines the target CG PUSCH resource according to the cell switching command, or takes the CG resource closest to the moment of receiving the cell switching command as the target CG PUSCH resource, and determines the scrambling code of the target CG PUSCH resource according to the first scrambling code factor and the second scrambling code factor.

[0248] Among them, the value of the first scrambling factor is configured by the network (high-level parameter dataScramblingIdentityPUSCH, the value of the first scrambling factor associated with all CG PUSCH resources allocated by the target cell to the source cell is the same) or the protocol stipulates (such as the physical cell identifier (Physical CellIdentifier, PCI) of the target cell), and the value of the second scrambling factor is calculated and generated by the terminal according to the time-frequency domain position of the target configuration authorized resource, that is, a new radio network temporary identifier (Radio NetworkTemporary Identifier, RNTI) indicating the CG PUSCH resource used for switching is introduced, which is similar to the random access RNTI (Random Access RNTI, RA-RNTI), and optionally, the value range is FFF4-FFFC.

[0249] In addition, the DMRS sequence of all CG PUSCH resources allocated by the target cell to the source cell is the same, and the DMRS of all CG PUSCH resources allocated by the target cell to the source cell are associated with the same scrambling configuration parameters, or the values ​​of the associated scrambling parameter configuration information (scramblingID0 and scramblingID1) are the same.

[0250] For the shared CG solution, there is a problem of how to implement scrambling of uplink data sent on the shared CG PUSCH. This embodiment can implement scrambling of uplink data sent on the shared CG PUSCH.

[0251] Example 3.3:

[0252] This embodiment provides a method of sharing the second information carried by the CG PUSCH.

[0253] The shared CG PUSCH carries at least the identity information of the UE in the target cell, such as C-RNTI, so that the target cell can determine the UE identity based on the received CG PUSCH to determine whether the handover is successful and perform data scheduling.

[0254] Example 3.4:

[0255] (1) The UE receives a cell handover command sent by the source cell, which includes CG PUSCH transmission configuration parameters, target cell CG PUSCH resource indication information, and beam indication information;

[0256] (2) The UE determines the target CG PUSCH resource according to the target cell CG PUSCH resource configuration indication information in the handover command, determines the first RNTI according to the time-frequency domain position of the to-be-used CG PUSCH resource, generates the scrambling code of the PUSCH according to the first RNTI and the first scrambling factor configured or indicated by the network side (for example, the PCI of the target cell); generates the PUSCH DMRS sequence according to the DMRS scrambling code parameters configured by the network side;

[0257] (3) The UE sends an initial uplink message in the target cell based on the target CG PUSCH resources, the scrambling code and the transmission configuration parameters; the uplink message carries the identity information of the UE in the target cell, such as C-RNTI.

[0258] For the shared CG solution, there is a problem that the target cell cannot determine the corresponding UE identity after receiving the CG PUSCH. By carrying the identity information of the UE in the target cell, it is easier for the network side to determine the corresponding UE identity.

[0259] It should be noted that the CG PUSCH mentioned in the above embodiment includes at least one of Type 1 CG PUSCH and Type 2 CGPUSCH.

[0260] In the first embodiment, the second embodiment and the third embodiment, the configuration of the mapping relationship between the beam and the CG PUSCH resource and the sharing configuration of the CGPUSCH resource are two independent schemes, which can be combined with each other. The specific combination scheme can be seen in Table 1.

[0261] Table 1

[0262]

[0263]

[0264]

[0265] In Table 1, "√" indicates that the Case includes the scheme of the corresponding table header. "×" indicates that the Case does not include the scheme of the corresponding table header. For example, in Case-1, the CG PUSCH resource is configured at the cell level (i.e., shared); and there is a mapping relationship between the beam and the CG PUSCH resource, and the mapping ratio between the beam and the CG PUSCH resource is greater than 1. The terminal sends the second information on the target CG PUSCH resource, specifically: the terminal determines the target CG PUSCH resource according to the mapping relationship between the beam and the CG PUSCH resource; the terminal determines the power control parameters and the transmit power of the second information sent on the CG PUSCH resource according to the scheme of embodiment one; the terminal determines at least one of the uplink sending port, TPMI and MCS according to the network configuration, configuration and indicated transmission configuration parameters; the terminal sends the second information on the target CG PUSCH resource; the second information includes the beam indication information included in the cell switching command, the identity of the terminal in the target cell, and the indication information of the successful cell switching.

[0266] It should be noted that for high-speed mobile scenarios, in order to reduce switching delay, Release 18 introduced L1 / L2-based cell switching (L1 / L2 Triggered Mobility, LTM). In related technologies, LTM supports two switching modes: rach-based and Rach-less. For the rach-based solution, the UE can inform the target cell that it has been accessed through the RACH procedure; for the Rach-less solution, the UE can inform the target cell through the beam-associated configured grant indicated in the associated cell switching command. However, in the Rach-less switching solution based on CG transmission, there are still the following deficiencies that need to be further resolved and improved:

[0267] (1) How the configured grant is associated with the beam has not yet been determined;

[0268] (2) The power control issue of the configured grant has not yet been determined;

[0269] (3) For a separate TCI, if the configured grant is associated with a downlink (DL) beam, how can the network determine its Rx beam based on the received CG?
