[0026] The following is an explanation of some concepts and / or terms involved in the data transmission method provided in the embodiments of the present application.

[0027] 1. LTM

[0028] In the R18 mobility enhancement project, LTM was introduced. Specifically, the serving base station determines the target cell based on the layer 1 measurement results of the UE, and uses MAC CE to trigger the UE to switch the primary cell or primary and secondary cells (or primary cell group or secondary cell group) to the target cell (or target cell group). During the LTM process, the network side will prepare multiple candidate cells in advance and send the configuration information of the candidate cells to the UE through RRC signaling. When the UE changes the cell, the configuration information of the candidate cells saved by the UE will not be actively released. Therefore, LTM can also be called continuous LTM.

[0029] In order to reduce the delay of cell change, during the LTM process, the NW can trigger the UE to obtain the timing advance (TA) value of the candidate cell in advance. TA is used for the UE's uplink transmission to ensure that the UE's uplink data packet reaches the base station within the desired time. Specifically, the NW sends a PDCCH order to the UE, which carries the identifier of the candidate cell. After receiving the PDCCH order, the UE sends a preamble to the candidate cell indicated by the PDCCH order. The candidate cell calculates the TA value of the UE based on the preamble. The R18 mobility enhance project agrees to carry the indication information of the candidate cell and the configuration information of the random access timing of the candidate cell in the PDCCH order that triggers the early acquisition of the TA of the candidate cell. There is 1 bit in the PDCCH order to clearly configure whether the PRACH is an initial transmission or a retransmission.

[0030] 2. R18 inter-cell mTRP

[0031] In addition to the SSB configured in the serving cell, the inter-cell mTRP transmission will also configure the SSB associated with the additionalPCI to measure the SSB of other physical cells. In this way, the UE's uplink and downlink data can be transmitted with the current cell and the adjacent physical cell at the same time, increasing the data transmission throughput.

[0032] In inter-cell mTRP transmission, since the TRP of the local cell and the TRP of the neighboring cell are generally deployed at different distances from the UE, uplink synchronization needs to be performed for the TRP of the local cell and the TRP of the neighboring cell respectively. Therefore, in addition to the RACH resource configuration of the local cell, the RACH resource configuration for each neighboring cell associated with the additional PCI will also be configured. The RACH process of the local cell and the neighboring cell is also triggered by the PDCCH order.

[0033] The resource configuration determination method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0034] During the LTM process, the RACH process of the candidate cell to be switched needs to be triggered in advance through PDCCH signaling to obtain uplink synchronization with the candidate cell in advance; R18 inter-cell mTRP, that is, multiple transmission and reception points between cells, needs to trigger the RACH process of the TRP of the current cell and the TRP of the neighboring cell through PDCCH signaling to obtain uplink synchronization of the two TRPs. Since the RACH resource configuration of the current cell, the RACH resource configuration of the candidate cell, and the RACH resource configuration of the neighboring cell are configured separately, when the UE performs LTM, or performs inter-cell mTRP transmission, or performs LTM and inter-cell mTRP transmission, the UE cannot determine which set of RACH resource configurations the resource-related configuration information sent by the PRACH indicated by the PDCCH signaling should be mapped to.

[0035] In the resource configuration determination method provided in an embodiment of the present application, the UE receives PDCCH signaling, and the PDCCH signaling is used to trigger a random access procedure; the UE determines the target RACH resource configuration corresponding to the random access procedure based on first information, the first information is associated with the PDCCH signaling, and the target RACH resource configuration is: at least one of the at least two RACH resource configurations configured for the UE. In this scheme, since the UE can determine the target RACH resource configuration corresponding to the random access procedure from the at least two RACH resource configurations configured for the UE based on the first information associated with the PDCCH signaling after receiving the PDCCH signaling, the UE can map the resource-related configuration information sent by the PRACH indicated by the PDCCH signaling to the target RACH resource configuration.

[0036] The present application provides a method for determining resource configuration. Figure 2 FIG. 1 is a flow chart of a method for determining resource configuration provided by an embodiment of the present application. Figure 2 As shown, the resource configuration determination method provided in the embodiment of the present application may include the following steps 201 and 202.

[0037] Step 201: UE receives PDCCH signaling.

[0038] In some embodiments of the present application, the above-mentioned PDCCH signaling is used to trigger a random access procedure.

[0039] In some embodiments of the present application, before receiving the PDCCH signaling, the UE may also receive a first signaling, where the first signaling is used to configure at least one of the following items for the UE: enabling the first transmission mode and enabling the second transmission mode.

[0040] In some embodiments of the present application, the first transmission mode is inter-cell mTRP transmission, and the second transmission mode is LTM transmission.

[0041] In some embodiments of the present application, the above-mentioned first transmission mode enabling indicates that the high-level signaling is configured with a single sideband (SynchronizationSignal / PBCH block, SSB) associated with an additional physical cell identifier (Physical Cell Identifier, PCI), and at the same time, the service cell is associated with two TAGs, and the second transmission mode enabling indicates that the high-level signaling includes LTM configuration.

[0042] In some embodiments of the present application, the high-layer signaling is the above-mentioned first signaling.

[0043] In some embodiments of the present application, the above-mentioned first signaling may also be used to configure at least two RACH resource configurations for the UE.

[0044] In some embodiments of the present application, the at least two RACH resource configurations include any of the following:

[0045] RACH resource configuration of the cell where the UE is located and the first set of RACH resource configuration;

[0046] RACH resource configuration of the cell where the UE is located and the second set of RACH resource configuration;

[0047] RACH resource configuration of the cell where the UE is located, the first set of RACH resource configuration, and the second set of RACH resource configuration;

[0048] The first set of RACH resource configuration includes the RACH resource configuration of the neighboring cells of the cell where the UE is located;

[0049] The second set of RACH resource configurations includes RACH resource configurations of candidate cells.

[0050] In some embodiments of the present application, the RACH resource configuration of the neighboring cell of the cell where the above UE is located is associated with the additionalPCI; the RACH resource configuration of the candidate cell is associated with the candidate cell index.

[0051] In some embodiments of the present application, the RACH resource configuration of the cell where the UE is located is the RACH resource configuration of the serving cell.

[0052] In some embodiments of the present application, the first transmission mode corresponds to a first set of RACH resource configurations, and the second transmission mode corresponds to a second set of RACH resource configurations.

[0053] In some embodiments of the present application, when the first signaling is used to enable the first transmission mode for the UE, the at least two RACH resource configurations may include: the RACH resource configuration of the cell where the UE is located and the first set of RACH resource configurations.

[0054] In some embodiments of the present application, when the first signaling is used to configure the second transmission mode enabling for the UE, the at least two RACH resource configurations may include: the RACH resource configuration of the cell where the UE is located and the second set of RACH resource configurations.

[0055] In some embodiments of the present application, when the above-mentioned first signaling is used to configure the first transmission mode enabling and the second transmission mode enabling for the UE, the above-mentioned at least two RACH resource configurations may include: the RACH resource configuration of the cell where the UE is located, the first set of RACH resource configurations, and the second set of RACH resource configurations.

[0056] Step 202: The UE determines a target RACH resource configuration corresponding to the random access procedure based on the first information.

[0057] In some embodiments of the present application, the above-mentioned first information is associated with PDCCH signaling, and the target RACH resource configuration is: at least one of at least two RACH resource configurations configured for the UE.

[0058] In some embodiments of the present application, the above-mentioned first information includes any one of the following: an indication field contained in PDCCH signaling, a signaling format of PDCCH signaling, and a PDCCH resource for transmitting PDCCH signaling.

[0059] In some embodiments of the present application, the indication field is used for the UE to determine at least one RACH resource configuration from at least two RACH resource configurations.

[0060] In some embodiments of the present application, the UE may determine the target RACH resource configuration based on the value of the indication field included in the PDCCH signaling.

[0061] In some embodiments of the present application, the numerical value contained in the above indication field may also be referred to as the numerical value corresponding to the indication field or the numerical value indicated by the indication field, etc. The embodiments of the present application are not limited to this.

[0062] In some embodiments of the present application, the above-mentioned PDCCH signaling may also be understood as DCI signaling sent on the PDCCH channel, for example: DCI format 1_0.

[0063] In some embodiments of the present application, the UE may monitor a PDCCH resource that transmits a PDCCH signaling, and determine a RACH resource configuration corresponding to the PDCCH resource as a target RACH resource configuration.

[0064] In some embodiments of the present application, when it is determined that the RACH resource configuration of the cell where the UE is located is the target RACH resource configuration, the UE does not interpret the cell indicator and the PRACH transmission indicator; when it is determined that the first set of RACH resource configuration is the target RACH resource configuration, the UE does not interpret the PRACH transmission indicator.

[0065] It should be noted that the detailed steps for the UE to determine the target RACH resource configuration based on the first information will be described in the following embodiments and will not be repeated here.

[0066] An embodiment of the present application provides a method for determining resource configuration, wherein a UE receives a PDCCH signaling, and the PDCCH signaling is used to trigger a random access procedure; the UE determines a target RACH resource configuration corresponding to the random access procedure based on first information, the first information is associated with the PDCCH signaling, and the target RACH resource configuration is: at least one of at least two RACH resource configurations configured for the UE. In this solution, since the UE can determine the target RACH resource configuration corresponding to the random access procedure from at least two RACH resource configurations configured for the UE based on the first information associated with the PDCCH signaling after receiving the PDCCH signaling, the UE can map the resource-related configuration information sent by the PRACH indicated by the PDCCH signaling to the target RACH resource configuration.

[0067] In some embodiments of the present application, the first information includes a PDCCH resource for transmitting PDCCH signaling; the PDCCH resource includes at least one resource, each resource corresponds to at least one RACH resource configuration of at least two RACH resource configurations; combined Figure 2 ,like Figure 3 As shown, the above step 201 can be specifically implemented through the following step 201a.

[0068] Step 201a: The UE receives PDCCH signaling on a first resource.

[0069] The first resource is one of at least one resource, and the target RACH resource configuration is the RACH resource configuration corresponding to the first resource.

[0070] In some embodiments of the present application, the protocol presets a correspondence between PDCCH resources and RACH resource configurations, so that when receiving PDCCH signaling, the UE can determine the RACH resource configuration corresponding to the first resource for transmitting the PDCCH signaling as the target RACH resource configuration based on the correspondence.

[0071] It can be understood that since PDCCH signaling is transmitted on PDCCH resources, the correspondence between PDCCH resources and RACH resource configurations can be configured so that when PDCCH signaling is monitored on a certain PDCCH resource, the UE can determine the RACH resource configuration corresponding to the certain PDCCH resource as the target RACH resource configuration.

[0072] In some embodiments of the present application, the PDCCH resources may be divided into first resources, second resources, and third resources, and then the first resources are set to correspond to the RACH resource configuration of the cell where the UE is located in at least two RACH resource configurations; the second resources correspond to the first set of RACH resource configurations in at least two RACH resource configurations; the third resources correspond to the second set of RACH resource configurations in at least two RACH resource configurations, and the corresponding relationship is sent to the UE.

[0073] For example, when the UE monitors the PDCCH signaling on the second resource, the first set of RACH resource configuration corresponding to the second resource may be determined as the target RACH resource configuration.

[0074] In some embodiments of the present application, the second resource corresponds to the first set of RACH resource configurations, which can be understood as the second resource corresponding to at least one RACH resource configuration in the first set of RACH resource configurations; similarly, the third resource corresponds to the second set of RACH resource configurations, which can be understood as the third resource corresponding to at least one RACH resource configuration in the second set of RACH resource configurations.

[0075] In some embodiments of the present application, the protocol may only preset the correspondence between the PDCCH resource and the first set of RACH resource configurations and the second set of RACH resource configurations. When the UE receives the PDCCH signaling on the first resource, the UE may further determine the target RACH resource configuration based on the RACH resource configuration corresponding to the first resource and the sixth indication field.

[0076] In some embodiments of the present application, when the RACH resource configuration indicated by the sixth indication field belongs to the RACH resource configuration corresponding to the first resource, the UE may use the RACH resource configuration indicated by the sixth indication field as the target RACH resource configuration; when the RACH resource configuration indicated by the sixth indication field does not belong to the RACH resource configuration corresponding to the first resource, the UE may use the RACH resource configuration of the cell in which the UE is located as the target RACH resource configuration.

[0077] In some embodiments of the present application, when the value included in the sixth indication field is a preset value, the UE may determine that the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located.

[0078] In some embodiments of the present application, when the value included in the sixth indication field is not a preset value, the UE may determine that the RACH resource configuration indicated by the sixth indication field is a certain RACH resource configuration in the RACH resource configuration corresponding to the first resource.

[0079] In some embodiments of the present application, when the RACH resource configuration corresponding to the first resource is the first set of RACH resource configurations, and the sixth indication field indicates a certain RACH resource configuration in the first set of RACH resource configurations, that is, the value contained in the sixth indication field is not a preset value, the UE can determine that the RACH resource configuration indicated by the sixth indication field belongs to the RACH resource configuration corresponding to the first resource, so that the UE can use the certain RACH resource configuration in the first set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration.

[0080] In some embodiments of the present application, the value range of the sixth indication field depends on the number of RACH resource configurations included in the first set of RACH resource configurations. When the number of RACH resource configurations included in the first set of RACH resource configurations is N, the value range of the value contained in the sixth indication field is 0-N, and 0 is a preset value.

[0081] In some embodiments of the present application, the bit length of the sixth indication field may be or

[0082] It can be understood that, when the value contained in the above-mentioned sixth indication field is 0, that is, the above-mentioned preset value, the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located; when the value contained in the sixth indication field is any one of 1-N, the RACH resource configuration indicated by the sixth indication field is a RACH resource configuration in the first set of RACH resource configurations.

[0083] Furthermore, an identifier may be assigned to each of the N RACH resource configurations included in the first set of RACH resource configurations, for example: RACH resource configuration_1-RACH resource configuration_N; wherein one identifier corresponds to a value in the above 1-N, for example: RACH resource configuration_1 corresponds to value 1, and the corresponding relationship is sent to the UE.

[0084] For example, when the value included in the sixth indication field is 6, the UE may determine, based on the value 6, that the RACH resource configuration indicated by the sixth indication field is RACH resource configuration_6 in the first set of RACH resource configurations.

[0085] In some embodiments of the present application, when the RACH resource configuration corresponding to the first resource is the second set of RACH resource configurations, and the sixth indication field indicates a certain RACH resource configuration in the second set of RACH resource configurations, that is, the value contained in the sixth indication field is not a preset value, the UE can determine that the RACH resource configuration indicated by the sixth indication field belongs to the RACH resource configuration corresponding to the first resource, so that the UE can use the certain RACH resource configuration in the second set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration.

[0086] In some embodiments of the present application, the value range of the sixth indication field depends on the number of RACH resource configurations included in the second set of RACH resource configurations. When the number of RACH resource configurations included in the second set of RACH resource configurations is M, the value range of the value contained in the sixth indication field is 0-M, where 0 is a preset value.

[0087] In some embodiments of the present application, the bit length of the sixth indication field may be or

[0088] It can be understood that, when the value contained in the above-mentioned sixth indication field is 0, that is, the above-mentioned preset value, the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located; when the value contained in the sixth indication field is any one of 1-M, the RACH resource configuration indicated by the sixth indication field is a RACH resource configuration in the second set of RACH resource configurations.

[0089] Furthermore, an identifier may be assigned to each of the M RACH resource configurations included in the second set of RACH resource configurations, for example: RACH resource configuration_1-RACH resource configuration_M; wherein one identifier corresponds to a value in the above 1-M, for example: RACH resource configuration_1 corresponds to value 1, and the corresponding relationship is sent to the UE.

[0090] For example, when the value included in the sixth indication field is 3, the UE may determine, based on the value 3, that the RACH resource configuration indicated by the sixth indication field is RACH resource configuration_3 in the second set of RACH resource configurations.

[0091] In some embodiments of the present application, when the RACH resource configuration corresponding to the first resource is the first set of RACH resource configurations, and the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located, that is, the value contained in the sixth indication field is a preset value, the UE can determine that the RACH resource configuration indicated by the sixth indication field does not belong to the RACH resource configuration corresponding to the first resource, so that the UE can use the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0092] In some embodiments of the present application, when the RACH resource configuration corresponding to the first resource is the second set of RACH resource configuration, and the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located, that is, the value contained in the fourth indication field is a preset value, the UE can determine that the RACH resource configuration indicated by the fourth indication field does not belong to the RACH resource configuration corresponding to the first resource, so that the UE can use the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0093] In this way, when the UE monitors PDCCH signaling on a certain PDCCH resource, it can determine the RACH resource configuration corresponding to the certain PDCCH resource as the target RACH resource configuration based on the correspondence between the PDCCH resource and the RACH resource configuration, thereby improving the flexibility of the UE in determining the target RACH resource configuration.

[0094] In some embodiments of the present application, the first information includes an indication field; Figure 2 ,like Figure 4 As shown, the above step 202 can be specifically implemented through the following step 202a.

[0095] Step 202a: The UE uses the RACH resource configuration indicated by the indication field as the target RACH resource configuration.

[0096] In some embodiments of the present application, the UE may determine the target RACH resource configuration based on a value included in the indication field.

[0097] In some embodiments of the present application, the protocol presets a correspondence between the value included in the indication field and the RACH resource configuration, so that when receiving PDCCH signaling, the UE can determine the target RACH resource configuration based on the indication field included in the PDCCH signaling.

[0098] It can be understood that after receiving the PDCCH signaling, the UE can parse the indication field included in the PDCCH signaling. When the indication field contains a certain value, the UE can determine the RACH resource configuration corresponding to the certain value as the target RACH resource configuration.

[0099] Exemplarily, a value 1 may be set to correspond to a RACH resource configuration of a cell in which the UE is located in at least two RACH resource configurations; a value 2 may correspond to a first set of RACH resource configurations in at least two RACH resource configurations; and a value 3 may correspond to a second set of RACH resource configurations in at least two RACH resource configurations.

[0100] For example, when the UE receives PDCCH signaling and parses the PDCCH signaling to find that the value corresponding to the indication field is 1, the UE may determine the RACH resource configuration of the cell where the UE is located corresponding to the value 1 as the target RACH resource configuration.

[0101] In some embodiments of the present application, the protocol may only preset the correspondence between the numerical value contained in the indication field and the first set of RACH resource configurations and the second set of RACH resource configurations. When the UE receives the PDCCH signaling, the target RACH resource configuration may be further determined based on the RACH resource configuration corresponding to the numerical value contained in the indication field in the PDCCH signaling and the sixth indication field.

[0102] In some embodiments of the present application, when the RACH resource configuration indicated by the sixth indication field belongs to the RACH resource configuration corresponding to the numerical value included in the indication field, the UE may use the RACH resource configuration indicated by the sixth indication field as the target RACH resource configuration; when the RACH resource configuration indicated by the sixth indication field does not belong to the RACH resource configuration corresponding to the numerical value included in the indication field, the UE may use the RACH resource configuration of the cell in which the UE is located as the target RACH resource configuration.

[0103] In some embodiments of the present application, when the value included in the sixth indication field is a preset value, the UE may determine that the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located.

[0104] In some embodiments of the present application, when the value included in the sixth indication field is not a preset value, the UE may determine that the RACH resource configuration indicated by the sixth indication field is: a RACH resource configuration among the RACH resource configurations corresponding to the value included in the indication field.

[0105] In some embodiments of the present application, when the RACH resource configuration corresponding to the value included in the indication field is the first set of RACH resource configurations, and the sixth indication field indicates a certain RACH resource configuration in the first set of RACH resource configurations, that is, the value included in the sixth indication field is not a preset value, the UE may determine that the RACH resource configuration indicated by the sixth indication field belongs to the RACH resource configuration corresponding to the value included in the indication field, so that the UE may use a certain RACH resource configuration in the first set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration.

[0106] For example, when the value included in the indicator field is 1 and the value included in the sixth indicator field is 5, the UE may determine RACH resource configuration_5 in the first set of RACH resource configuration as the target RACH resource configuration.

[0107] It should be noted that, for the detailed steps of determining a certain RACH resource configuration in the first set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration, reference may be made to the description in the above embodiment, which will not be repeated here.

[0108] In some embodiments of the present application, when the RACH resource configuration corresponding to the value included in the indication field is the second set of RACH resource configurations, and the sixth indication field indicates a certain RACH resource configuration in the second set of RACH resource configurations, that is, the value included in the sixth indication field is not a preset value, the UE may determine that the RACH resource configuration indicated by the sixth indication field belongs to the RACH resource configuration corresponding to the value included in the indication field, so that the UE may use a certain RACH resource configuration in the second set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration.

[0109] For example, when the value included in the indicator field is 2 and the value included in the sixth indicator field is 4, the UE may determine RACH resource configuration_4 in the second set of RACH resource configuration as the target RACH resource configuration.

[0110] It should be noted that, for the detailed steps of determining a certain RACH resource configuration in the second set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration, reference may be made to the description in the above embodiment, which will not be repeated here.

[0111] In some embodiments of the present application, when the RACH resource configuration corresponding to the value included in the indication field is the first set of RACH resource configuration, and the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located, that is, the value included in the sixth indication field is a preset value, the UE can determine that the RACH resource configuration indicated by the sixth indication field does not belong to the RACH resource configuration corresponding to the value included in the indication field, so that the UE can use the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0112] For example, when the value included in the indication field is 1 and the value included in the sixth indication field is 0, the UE may determine the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0113] In some embodiments of the present application, when the RACH resource configuration corresponding to the value included in the indication field is the second set of RACH resource configuration, and the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located, that is, the value included in the sixth indication field is a preset value, the UE can determine that the RACH resource configuration indicated by the sixth indication field does not belong to the RACH resource configuration corresponding to the value included in the indication field, so that the UE can use the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0114] For example, when the value included in the indicator field is 2 and the value included in the sixth indicator field is 0, the UE may determine the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0115] In this way, after receiving the PDCCH signaling, the UE can parse the indication field included in the PDCCH signaling, so as to determine the RACH resource configuration corresponding to a certain value as the target RACH resource configuration when the indication field contains a certain value, thereby improving the flexibility and diversity of the UE in determining the target RACH resource configuration.

[0116] In some embodiments of the present application, the first information includes an indication field, which includes a first indication field and a second indication field; the step 202 can be implemented by the following step 202b or step 202c.

[0117] Step 202b: When the values ​​of the first indication field and the second indication field are both preset values, the UE uses the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration;

[0118] In some embodiments of the present application, the UE may determine the target RACH resource configuration based on the values ​​respectively included in the first indication field and the second indication field.

[0119] In some embodiments of the present application, the protocol presets a correspondence between the RACH resource configuration of the cell where the UE is located and a preset value, so that when it is parsed that the values ​​respectively included in the first indication field and the second indication field are both preset values, the UE can determine the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0120] For example, the preset value may be 0. When the UE finds that both the first indication field and the second indication field contain values ​​of 0, the UE may determine that the RACH resource configuration of the cell where the UE is located is the target RACH resource configuration.

[0121] Step 202c: When the values ​​of the first indication field and the second indication field are different, the UE uses the RACH resource configuration indicated by the target indication field as the target RACH resource configuration.

[0122] In some embodiments of the present application, the value of the above-mentioned target indication field is not a preset value.

[0123] In some embodiments of the present application, when the first value included in the first indication field and the second value included in the second indication field are different, the UE may use the RACH resource configuration indicated by the target indication field as the target RACH resource configuration.

[0124] In some embodiments of the present application, the first indication field corresponds to a first set of RACH resource configurations; and the second indication field corresponds to a second set of RACH resource configurations.

[0125] Exemplarily, when the value contained in the first indication field is non-zero and the value contained in the second indication field is 0, that is, the preset value, the UE can determine that the target indication field is the first indication field, so that the UE can use the first set of RACH resource configuration corresponding to the first indication field as the target RACH resource configuration.

[0126] For example, when the UE receives PDCCH signaling and parses the first indication field included in the PDCCH signaling to have a value of 5 and a value of 0, the UE may use the first set of RACH resource configuration indicated by the first indication field as the target RACH resource configuration.

[0127] Exemplarily, when the value contained in the first indication field is 0, that is, the preset value, and the value contained in the second indication field is non-0, the UE can determine that the target indication field is the second indication field, so that the UE can use the second set of RACH resource configuration corresponding to the second indication field as the target RACH resource configuration.

[0128] For example, when the UE receives PDCCH signaling and parses the first indication field included in the PDCCH signaling to have a value of 0 and a value of 2, the UE may use the second set of RACH resource configuration indicated by the second indication field as the target RACH resource configuration.

[0129] In this way, after receiving the PDCCH signaling, the UE can parse the first indication field and the second indication field included in the PDCCH signaling, and when the values ​​of the first indication field and the second indication field are both preset values, the RACH resource configuration of the cell where the UE is located is used as the target RACH resource configuration; when the values ​​of the first indication field and the second indication field are different, the RACH resource configuration indicated by the target indication field is used as the target RACH resource configuration, thereby improving the flexibility and diversity of the UE in determining the target RACH resource configuration.

[0130] In some embodiments of the present application, the first information includes an indication field; the indication field includes a third indication field and a fourth indication field; the third indication field indicates any one of the following: the RACH resource configuration of the cell where the UE is located and the first set of RACH resource configurations, the RACH resource configuration of the cell where the UE is located and the second set of RACH resource configurations; the first set of RACH resource configurations includes the RACH resource configurations of the neighboring cells of the cell where the UE is located; the second set of RACH resource configurations includes the RACH resource configurations of the candidate cells; the above step 202 can be specifically implemented by the following step 202d, or step 202e, or step 202f, or step 202g.

[0131] Step 202d: When the third indication field indicates the RACH resource configuration of the cell where the UE is located and the first set of RACH resource configurations, and the RACH resource configuration indicated by the fourth indication field belongs to the first set of RACH resource configurations, the UE uses the first set of RACH resource configurations as the target RACH resource configurations.

[0132] In some embodiments of the present application, after receiving the PDCCH signaling, the UE can obtain the third indication field and the fourth indication field contained in the PDCCH signaling. When the third indication field indicates the RACH resource configuration of the cell where the UE is located and the first set of RACH resource configurations, the UE can determine the RACH resource configuration indicated by the fourth indication field based on the value contained in the fourth indication field, so that when the RACH resource configuration indicated by the fourth indication field belongs to the first set of RACH resource configurations, the first set of RACH resource configurations is used as the target RACH resource configuration.

[0133] In some embodiments of the present application, the protocol presets a correspondence between a numerical value contained in a third indication field and a first configuration, where the first configuration is any one of the following: a RACH resource configuration of a cell where the UE is located and a first set of RACH resource configurations, a RACH resource configuration of a cell where the UE is located and a second set of RACH resource configurations, and is sent to the UE, so that when receiving PDCCH signaling, the UE can determine the RACH resource configuration indicated by the third indication field based on the third indication field included in the PDCCH signaling.

[0134] Exemplarily, the value 1 may be set to correspond to the RACH resource configuration of the cell where the UE is located and the first set of RACH resource configurations; the value 2 may be set to correspond to the RACH resource configuration of the cell where the UE is located and the second set of RACH resource configurations.

[0135] In some embodiments of the present application, when the value included in the fourth indication field is not a preset value, the UE may determine that the RACH resource configuration indicated by the fourth indication field belongs to the first set of RACH resource configurations.

[0136] For example, when the value contained in the third indication field is 1 and the value contained in the fourth indication field is 5, the UE can determine that the third indication field indicates the RACH resource configuration of the cell where the UE is located and the first set of RACH resource configurations, and the RACH resource configuration indicated by the fourth indication field belongs to the first set of RACH resource configurations, so that the UE can determine the first set of RACH resource configurations as the target RACH resource configuration.

[0137] Step 202e: When the third indication field indicates the RACH resource configuration of the cell where the UE is located and the first set of RACH resource configurations, and the RACH resource configuration indicated by the fourth indication field does not belong to the first set of RACH resource configurations, the UE uses the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0138] In some embodiments of the present application, after receiving the PDCCH signaling, the UE can obtain the third indication field and the fourth indication field contained in the PDCCH signaling. When the third indication field indicates the RACH resource configuration of the cell where the UE is located and the first set of RACH resource configurations, the UE can determine the RACH resource configuration indicated by the fourth indication field based on the value contained in the fourth indication field, so that when the RACH resource configuration indicated by the fourth indication field does not belong to the first set of RACH resource configurations, the RACH resource configuration of the cell where the UE is located is used as the target RACH resource configuration.

[0139] In some embodiments of the present application, when the value contained in the fourth indication field is a preset value, the UE may determine that the RACH resource configuration indicated by the fourth indication field is the RACH resource configuration of the cell where the UE is located, that is, the RACH resource configuration indicated by the fourth indication field does not belong to the first set of RACH resource configurations.

[0140] For example, when the value contained in the third indication field is 1 and the value contained in the fourth indication field is 0, the UE can determine that the third indication field indicates the RACH resource configuration of the cell where the UE is located and the first set of RACH resource configurations, and the RACH resource configuration indicated by the fourth indication field does not belong to the first set of RACH resource configurations, so that the UE can determine the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0141] Step 202f: When the third indication field indicates the RACH resource configuration of the cell where the UE is located and the second set of RACH resource configurations, and the RACH resource configuration indicated by the fourth indication field belongs to the second set of RACH resource configurations, the UE uses the second set of RACH resource configurations as the target RACH resource configurations.

[0142] In some embodiments of the present application, after receiving the PDCCH signaling, the UE can obtain the third indication field and the fourth indication field contained in the PDCCH signaling. When the third indication field indicates the RACH resource configuration and the second set of RACH resource configurations of the cell where the UE is located, the UE can determine the RACH resource configuration indicated by the fourth indication field based on the value contained in the fourth indication field, so that when the RACH resource configuration indicated by the fourth indication field belongs to the second set of RACH resource configurations, the second set of RACH resource configurations is used as the target RACH resource configuration.

[0143] For example, when the value contained in the third indication field is 2 and the value contained in the fourth indication field is 5, the UE can determine that the third indication field indicates the RACH resource configuration and the second set of RACH resource configurations of the cell where the UE is located, and the RACH resource configuration indicated by the fourth indication field belongs to the second set of RACH resource configurations, so that the UE can determine the second set of RACH resource configurations as the target RACH resource configurations.

[0144] Step 202g: When the third indication field indicates the RACH resource configuration of the cell where the UE is located and the second set of RACH resource configurations, and the RACH resource configuration indicated by the fourth indication field does not belong to the second set of RACH resource configurations, the UE uses the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0145] In some embodiments of the present application, after receiving the PDCCH signaling, the UE can obtain the third indication field and the fourth indication field contained in the PDCCH signaling. When the third indication field indicates the RACH resource configuration of the cell where the UE is located and the second set of RACH resource configurations, the UE can determine the RACH resource configuration indicated by the fourth indication field based on the value contained in the fourth indication field, so that when the RACH resource configuration indicated by the fourth indication field does not belong to the second set of RACH resource configurations, the RACH resource configuration of the cell where the UE is located is used as the target RACH resource configuration.

[0146] For example, when the value contained in the third indication field is 2 and the value contained in the fourth indication field is 0, the UE can determine that the third indication field indicates the RACH resource configuration of the cell where the UE is located and the second set of RACH resource configurations, and the RACH resource configuration indicated by the fourth indication field does not belong to the second set of RACH resource configurations, so that the UE can determine the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0147] In this way, after receiving the PDCCH signaling, the UE can obtain the third indication field and the fourth indication field included in the PDCCH signaling, and determine the target RACH resource configuration based on the indication of the third indication field and the indication of the fourth indication field, thereby improving the flexibility and diversity of the UE in determining the target RACH resource configuration.

[0148] In some embodiments of the present application, the first information includes a signaling format of a PDCCH signaling; Figure 2 ,like Figure 5 As shown, the above step 202 can be specifically implemented through the following step 202h.

[0149] Step 202h: The UE uses the RACH resource configuration corresponding to the signaling format of the PDCCH signaling among the at least two RACH resource configurations as the target RACH resource configuration.

[0150] In some embodiments of the present application, the protocol presets the correspondence between the signaling format and the RACH resource configuration and sends it to the UE, so that when receiving the PDCCH signaling, the UE can determine the target RACH resource configuration based on the signaling format of the PDCCH signaling.

[0151] It can be understood that after receiving the PDCCH signaling, the UE can obtain the signaling format of the PDCCH signaling, so as to determine the RACH resource configuration corresponding to the signaling format as the target RACH resource configuration.

[0152] Exemplarily, signaling format 1 may be set to correspond to the RACH resource configuration of the cell in which the UE is located in at least two RACH resource configurations; signaling format 2 may correspond to the first set of RACH resource configurations in at least two RACH resource configurations; and signaling format 3 may correspond to the second set of RACH resource configurations in at least two RACH resource configurations.

[0153] For example, when the UE receives PDCCH signaling and parses the signaling format of the PDCCH signaling as PDCCH format1_0, ie, the signaling format 1, the UE may determine the RACH resource configuration of the cell where the UE is located corresponding to the signaling format 1 as the target RACH resource configuration.

[0154] In some embodiments of the present application, the protocol may only preset the correspondence between the signaling format and the first set of RACH resource configurations and the second set of RACH resource configurations, and send the correspondence to the UE. When the UE receives the PDCCH signaling, it may further determine the target RACH resource configuration based on the RACH resource configuration corresponding to the signaling format of the PDCCH signaling and the sixth indication field.

[0155] In some embodiments of the present application, when the RACH resource configuration indicated by the sixth indication field belongs to the RACH resource configuration corresponding to the signaling format, the UE may use the RACH resource configuration indicated by the sixth indication field as the target RACH resource configuration; when the RACH resource configuration indicated by the sixth indication field does not belong to the RACH resource configuration corresponding to the signaling format, the UE may use the RACH resource configuration of the cell in which the UE is located as the target RACH resource configuration.

[0156] In some embodiments of the present application, when the value included in the sixth indication field is a preset value, the UE may determine that the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located.

[0157] In some embodiments of the present application, when the value included in the sixth indication field is not a preset value, the UE may determine that the RACH resource configuration indicated by the sixth indication field is: a certain RACH resource configuration in the RACH resource configuration corresponding to the signaling format.

[0158] In some embodiments of the present application, when the RACH resource configuration corresponding to the signaling format is the first set of RACH resource configurations, and the sixth indication field indicates a certain RACH resource configuration in the first set of RACH resource configurations, that is, the value contained in the sixth indication field is not a preset value, the UE can determine that the RACH resource configuration indicated by the sixth indication field belongs to the RACH resource configuration corresponding to the signaling format, so that the UE can use the certain RACH resource configuration in the first set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration.

[0159] For example, when the signaling format is signaling format 1 and the value included in the sixth indication field is 5, the UE may determine RACH resource configuration_5 in the first set of RACH resource configuration as the target RACH resource configuration.

[0160] It should be noted that, for the detailed steps of determining a certain RACH resource configuration in the first set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration, reference may be made to the description in the above embodiment, which will not be repeated here.

[0161] In some embodiments of the present application, when the RACH resource configuration corresponding to the signaling format is the second set of RACH resource configurations, and the sixth indication field indicates a certain RACH resource configuration in the second set of RACH resource configurations, that is, the value contained in the sixth indication field is not a preset value, the UE can determine that the RACH resource configuration indicated by the sixth indication field belongs to the RACH resource configuration corresponding to the signaling format, so that the UE can use a certain RACH resource configuration in the second set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration.

[0162] For example, when the signaling format is signaling format 2 and the value included in the sixth indication field is 7, the UE may determine RACH resource configuration_7 in the second set of RACH resource configuration as the target RACH resource configuration.

[0163] It should be noted that, for the detailed steps of determining a certain RACH resource configuration in the second set of RACH resource configurations indicated by the sixth indication field as the target RACH resource configuration, reference may be made to the description in the above embodiment, which will not be repeated here.

[0164] In some embodiments of the present application, when the RACH resource configuration corresponding to the signaling format is the first set of RACH resource configuration, and the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located, that is, the value contained in the sixth indication field is a preset value, the UE can determine that the RACH resource configuration indicated by the sixth indication field does not belong to the RACH resource configuration corresponding to the signaling format, so that the UE can use the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0165] For example, when the signaling format is signaling format 1 and the value included in the sixth indication field is 0, the UE may determine the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0166] In some embodiments of the present application, when the RACH resource configuration corresponding to the signaling format is the second set of RACH resource configuration, and the RACH resource configuration indicated by the sixth indication field is the RACH resource configuration of the cell where the UE is located, that is, the value contained in the sixth indication field is a preset value, the UE can determine that the RACH resource configuration indicated by the sixth indication field does not belong to the RACH resource configuration corresponding to the signaling format, so that the UE can use the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0167] For example, when the signaling format is signaling format 2 and the value contained in the sixth indication field is 0, the UE may determine the RACH resource configuration of the cell where the UE is located as the target RACH resource configuration.

[0168] In this way, after receiving the PDCCH signaling, the UE can obtain the signaling format of the PDCCH signaling to determine the RACH resource configuration corresponding to the signaling format as the target RACH resource configuration, thereby improving the flexibility and diversity of the UE in determining the target RACH resource configuration.

[0169] In some embodiments of the present application, the above-mentioned PDCCH signaling includes a fifth indication field; the above-mentioned step 202 can be specifically implemented through the following steps 202i and 202j.

[0170] Step 202i: The UE determines a first RACH resource configuration from at least two RACH resource configurations based on the first information.

[0171] The first RACH resource configuration is a first set of RACH resource configuration or a second set of RACH resource configuration.

[0172] The first set of RACH resource configuration includes the RACH resource configuration of the neighboring cells of the cell where the UE is located;

[0173] The second set of RACH resource configurations includes RACH resource configurations of candidate cells.

[0174] In some embodiments of the present application, after the UE first determines the first set of RACH resource configurations or the second set of RACH resource configurations from at least two RACH resource configurations based on the indication field, or the signaling format of the PDCCH signaling, or the PDCCH resource for transmitting the PDCCH signaling, the UE may further determine the target RACH resource configuration from the first set of RACH resource configurations or the second set of RACH resource configurations based on the fifth indication field.

[0175] It should be noted that, for the detailed steps of the UE determining the first RACH resource configuration from at least two RACH resource configurations based on the first information, reference may be made to the description in the above embodiment, which will not be repeated here.

[0176] Step 202j: The UE determines a target RACH resource configuration from the first RACH resource configuration based on the fifth indication field.

[0177] In some embodiments of the present application, the protocol presets a correspondence between the numerical value contained in the fifth indication field and the N RACH resource configurations in the first set of RACH resource configurations, and sends it to the UE, so that when receiving the PDCCH signaling, the UE can determine which RACH resource configuration in the first set of RACH resource configurations is indicated by the fifth indication field based on the fifth indication field included in the PDCCH signaling.

[0178] In some embodiments of the present application, the value range of the fifth indication field depends on the number of RACH resource configurations included in the first set of RACH resource configurations. When the number of RACH resource configurations included in the first set of RACH resource configurations is N, the value range of the value contained in the fifth indication field is 0-N, and 0 is a preset value.

[0179] In some embodiments of the present application, the bit length of the fifth indication field may be or

[0180] It can be understood that when the value included in the fifth indication field is any one of 1-N, the RACH resource configuration indicated by the fifth indication field is the RACH resource configuration corresponding to the value included in the fifth indication field in the first set of RACH resource configurations.

[0181] For example, when the value included in the fifth indication field is 6, the UE may determine, based on the value 6, that the RACH resource configuration indicated by the fifth indication field is RACH resource configuration_6 in the first set of RACH resource configurations.

[0182] In some embodiments of the present application, when the value contained in the fifth indication field is 0, that is, the preset value, the RACH resource configuration indicated by the fifth indication field is the RACH resource configuration of the cell where the UE is located.

[0183] In some embodiments of the present application, the protocol presets a correspondence between the numerical value contained in the fifth indication field and the N RACH resource configurations in the second set of RACH resource configurations, and sends it to the UE, so that when receiving the PDCCH signaling, the UE can determine which RACH resource configuration in the second set of RACH resource configurations is indicated by the fifth indication field based on the fifth indication field included in the PDCCH signaling.

[0184] In some embodiments of the present application, the value range of the fifth indication field depends on the number of RACH resource configurations included in the second set of RACH resource configurations. When the number of RACH resource configurations included in the second set of RACH resource configurations is N, the value range of the value contained in the fifth indication field is 0-M, and 0 is a preset value.

[0185] In some embodiments of the present application, the bit length of the fifth indication field may be or

[0186] It can be understood that when the value included in the fifth indication field is any one of 1-M, the RACH resource configuration indicated by the fifth indication field is the RACH resource configuration corresponding to the value included in the fifth indication field in the second set of RACH resource configurations.

[0187] For example, when the value included in the fifth indication field is 3, the UE may determine, based on the value 6, that the RACH resource configuration indicated by the fifth indication field is RACH resource configuration_3 in the second set of RACH resource configurations.

[0188] In some embodiments of the present application, when the value contained in the fifth indication field is 0, that is, the preset value, the RACH resource configuration indicated by the fifth indication field is the RACH resource configuration of the cell where the UE is located;

[0189] In some embodiments of the present application, when the RACH resource configuration indicated by the fifth indication field is the first set of RACH resource configurations, and the first set of RACH resource configurations includes N RACH resource configurations, the size of the fifth indication field depends on the maximum value of N; when the RACH resource configuration indicated by the fifth indication field is the first set of RACH resource configurations, and the first set of RACH resource configurations includes M RACH resource configurations, the size of the fifth indication field depends on the maximum value of M.

[0190] The resource configuration determination method provided in the embodiment of the present application can be executed by a resource configuration determination device. In the embodiment of the present application, the resource configuration determination device executing the resource configuration determination method is taken as an example to illustrate the resource configuration determination device provided in the embodiment of the present application.

[0191] Figure 6 FIG. 1 shows a possible structural diagram of a resource configuration determination device involved in an embodiment of the present application. Figure 6 As shown, the resource configuration determination device 80 may include: a receiving module 81 and a determination module 82 .

[0192] The receiving module 81 is used to receive physical downlink control channel PDCCH signaling, and the PDCCH signaling is used to trigger a random access procedure.

[0193] The determination module 82 is used to determine a target random access channel RACH resource configuration based on first information, where the first information is associated with PDCCH signaling, and the target RACH resource configuration is at least one of at least two RACH resource configurations configured for the UE.

[0194] An embodiment of the present application provides a resource configuration determination device. Since the resource configuration determination device can determine the target RACH resource configuration corresponding to the random access procedure from at least two RACH resource configurations configured for the resource configuration determination device based on the first information associated with the PDCCH signaling after receiving the PDCCH signaling, the resource configuration determination device can map the resource-related configuration information sent by the PRACH indicated by the PDCCH signaling to the target RACH resource configuration.
