[0199] In some embodiments, the core network device may be a single device or multiple devices or a device group. The core network may include at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0200] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly explaining the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. As can be known to those of ordinary skill in the art, with the evolution of the system architecture and the emergence of new service scenarios, the technical solutions proposed in the embodiments of the present disclosure are equally applicable to similar technical problems.

[0201] The following embodiments of the present disclosure can be applied to Figure 1 the communication system 100 shown in the figure, or part of the main body, but not limited thereto. Figure 1 Each main body shown in the figure is an example. The communication system may include Figure 1 all or part of the main bodies in the figure, or may also include Figure 1 other main bodies outside the figure.

[0202] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, the 4th generation mobile communication system (4G), the 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems extended based on them, etc. In addition, multiple systems can be combined (e.g., a combination of LTE or LTE-A and 5G, etc.) and applied.

[0203] In some embodiments of the present disclosure, to improve the downlink coverage of Msg2 / Msg4 / MsgB, the downlink coverage performance can be improved by means of Msg2 / Msg4 / MsgB repetition. To facilitate the network device to determine the repetition times of Msg2 / Msg4 / MsgB, the terminal device needs to report auxiliary information to assist the network device in determining the repetition times. The auxiliary information can be one or more of the following:

[0204] Downlink signal quality, such as Channel Quality Indicator (CQI) or Reference Signal Received Power (RSRP) of the downlink reference point;

[0205] Suggested repetition times;

[0206] Whether the terminal device supports Msg2 / Msg4 / MsgB repetition.

[0207] In some embodiments, NR supports configuring different Physical Random Access Channel (PRACH) resources for different Feature combinations. Feature combination can support the combination of the following Features:

[0208] Msg3 repetition;

[0209] Msg1 repetition;

[0210] RedCap: Reduced capability;

[0211] Small Data;

[0212] Network slice access layer group (NSAG): slice.

[0213] In some embodiments, during a random access procedure, after a terminal device fails in a random access attempt, it needs to perform a random access attempt again until the maximum number of random access attempts is reached. When the terminal device performs different random access attempts, it may switch between contention based random access (CBRA) and contention free random access (CFRA), or switch from 2-STEP RA to 4-step RA, or change the number of Msg1 repetitions.

[0214] In some embodiments, for the random access channel (RACH) procedures of Msg2 / Msg4 / MsgB repetition, the network device configures different RACH resources for different repetitions / RSRP thresholds / CQI thresholds. If the terminal device only selects the RACH resources corresponding to one repetition / RSRP threshold / CQI threshold, there may be a situation where the network device does not configure a feature combination that supports the repetition / RSRP threshold / CQI threshold, resulting in the terminal being unable to select the corresponding RACH resources.

[0215] Figure 2 It is an interaction schematic diagram of an information reporting method shown according to an embodiment of the present disclosure. This method can be executed by the above communication system. As Figure 2 shown, this method may include:

[0216] Step S201, the terminal device determines to report second information.

[0217] In some embodiments, this second information can be used for the network device to retransmit third information.

[0218] In some embodiments, this second information can be used to indicate the number of repetitions of sending this third information.

[0219] In some embodiments, this second information may include at least one of the following:

[0220] The quality of the first downlink signal;

[0221] The number of repetitions;

[0222] Whether the terminal device supports the retransmission of downlink information.

[0223] In some embodiments, this quality of the first downlink signal can be the downlink signal quality measured by the terminal device.

[0224] In some embodiments, the first downlink signal quality may include at least one of the following:

[0225] The RSRP of the downlink path loss reference point, the CQI of the downlink path loss reference point, the RSRP of the Physical Downlink Control Channel (PDCCH), and the CQI of the PDCCH.

[0226] It should be noted that the first downlink signal quality may further include other parameters that can reflect the downlink channel quality as specified by the protocol. The embodiments of the present disclosure do not limit this. The terminal device may obtain the first downlink signal quality according to the manner specified by the protocol, which will not be elaborated here.

[0227] In some embodiments, the name of the second information is not limited. For example, it may be "auxiliary information", "information for assisting the retransmission of downlink information", "information indicating the number of retransmissions", etc.

[0228] In some embodiments, the third information may be a downlink message for random access.

[0229] In some embodiments, the downlink information may include at least one of the following: Msg2, Msg4, MsgB.

[0230] In some embodiments, the bearing manner of the downlink information may include at least one of the following:

[0231] PDCCH;

[0232] Physical Downlink Shared Channel (PDSCH).

[0233] In some embodiments, the second information may include the reported value of the Msg2 / Msg4 / MsgB repetition (repetition) auxiliary information.

[0234] In some embodiments, the Msg2 / Msg4 / MsgB repetition auxiliary information may include Msg2 / Msg4 / MsgB PDCCH repetition and / or Msg2 / Msg4 / MsgB PDSCH repetition.

[0235] In some embodiments, the terminal device may determine to report the second information through at least one of the following manners:

[0236] Determine to report the second information according to the first configuration information;

[0237] Determine to report the second information according to the first downlink signal quality.

[0238] In some embodiments, the first configuration information may be used to indicate RACH configuration.

[0239] In some embodiments, the terminal device may determine to report the second information according to the first downlink signal quality. For example, when the terminal device determines that the first downlink signal quality is less than or equal to the first signal quality threshold, it determines to report the second information. The first signal quality threshold may be a signal quality threshold specified by a protocol or a signal quality threshold obtained through testing. Embodiments of the present disclosure do not limit this.

[0240] In some embodiments, the terminal device may determine to report the second information according to the first configuration information.

[0241] In some embodiments, the terminal device may determine to report the second information according to the first configuration information through at least one of the following:

[0242] Determine that the first configuration information includes a contention free random access (CFRA) resource for the terminal device to perform random access. The CFRA resource includes a first RACH resource that supports reporting of the second information and does not include RACH resources other than the first RACH resource, and determine to report the second information;

[0243] Determine that the random access request sent by the terminal device is triggered based on the system information SI, and the RACH resource used to send the SI includes the first RACH resource and does not include RACH resources other than the first RACH resource, and determine to report the second information;

[0244] Determine that the bandwidth part (BWP) of the random access request sent by the terminal device includes the first RACH resource and does not include RACH resources other than the first RACH resource, and determine to report the second information.

[0245] For example, if the first configuration information configures a CFRA resource for the terminal device's current random access, and the CFRA originally only includes RACH resources that support reporting of the second information, then determine to report the second information.

[0246] For another example, if the terminal device's current random access is triggered by an SI request, and the RACH resource used for the SI request only includes RACH resources that support reporting of the second information, then determine to report the second information.

[0247] For still another example, if only RACH resources that support reporting of the second information are configured on the BWP where the terminal device initiates RACH, then determine to report the second information.

[0248] Step S202: The terminal device determines all the characteristics of the first RACH resource set that can be used to trigger the terminal device to perform random access.

[0249] In some embodiments, the first configuration information may include multiple RACH resource sets.

[0250] In some embodiments, the first RACH resource set may include at least one RACH resource set in the first configuration information.

[0251] In some embodiments, the characteristics may include at least one of the following:

[0252] Msg3 repetition;

[0253] Msg1 repetition;

[0254] RedCap;

[0255] SmallData (small data);

[0256] NSAG.

[0257] In some embodiments, if all the characteristics for the terminal device to perform random access include Msg3 repetition, Msg1 repetition, RedCap, SmallData, and NSAG, then the RACH resource set in the multiple RACH resource sets of the first configuration information that can be used to trigger all the characteristics for the terminal device to perform random access can be used as the first RACH resource set.

[0258] Step S203: The terminal device determines that the first RACH resource set includes one RACH resource set, and uses the fourth information corresponding to the first RACH resource set as the second information.

[0259] In some embodiments, the fourth information may include at least one of the following: RSRP, CQI, number of repetitions.

[0260] In some embodiments, if it is determined that the first RACH resource set includes only one RACH resource set, then the fourth information corresponding to the first RACH resource set can be used as the second information.

[0261] Step S204: The terminal device reports the second information to the network device via Msg1 or MsgA.

[0262] In some embodiments, the network device may receive the second information. For example, the network device may receive the second information sent by the terminal device. For another example, the network device may also receive the second information sent by other entities.

[0263] In some embodiments, the terminal device may report the second information to the network device via Msg1.

[0264] In some embodiments, the terminal device may report the second information to the network device via MsgA.

[0265] In some embodiments, the terminal device may distinguish different second information via different RACH resource sets, that is, different RACH resource sets correspond to different second information.

[0266] It should be noted that the terminal device may also report the second information via other uplink information specified by the protocol, and the embodiments of the present disclosure do not limit this.

[0267] By adopting the above method, when determining that the second information needs to be reported, the terminal device may determine the second information based on multiple configured RACH resources. In this way, the terminal device may select the most suitable RACH resource for random access.

[0268] The method involved in the embodiments of the present disclosure may include at least one of the above steps S201 to step S204. For example, step S201 may be implemented as an independent embodiment, step S204 may be implemented as an independent embodiment, step S202 + step S203 may be implemented as an independent embodiment, and step S202 + step S203 + step S204 may be implemented as an independent embodiment, but it is not limited thereto.

[0269] In some embodiments, reference may be made to Figure 2 other optional implementation manners described before or after the corresponding specification.

[0270] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments.

[0274] Figure 3 It is an interaction schematic diagram of an information reporting method shown according to an embodiment of the present disclosure. This method may be executed by the above communication system. As Figure 3 shown, this method may include:

[0275] Step S301, the terminal device determines to report second information.

[0276] For the optional implementation of this step S301, reference may be made to Figure 2 the optional implementation of step S201 in Figure 2 and other related parts in the involved embodiments, which will not be elaborated here.

[0278] For the optional implementation of this step S302, reference may be made to Figure 2 the optional implementation of step S202 in Figure 2 and other related parts in the involved embodiments, which will not be elaborated here.

[0279] Step S303, the terminal device determines that the first RACH resource set includes multiple RACH resource sets.

[0280] Step S304, the terminal device determines a first mapping value according to the first downlink signal quality and the first association relationship.

[0281] In some embodiments, the first association relationship may include a correspondence between different downlink signal qualities and mapping values.

[0282] In some embodiments, the first association relationship may be predefined.

[0283] Among them, the mapping values may include positive integers such as 1, 2, 4, 8, etc., and the embodiments of the present disclosure do not limit this.

[0284] In some embodiments, the mapping value corresponding to the first downlink signal quality in the first association relationship may be used as the first mapping value.

[0285] Step S305: The terminal device determines at least one first reporting value according to the first mapping value and the second mapping value supported by the network device.

[0286] In some embodiments, the terminal device may pre-store the second mapping value supported by the network device.

[0287] In some embodiments, the terminal device may also obtain the second mapping value from the network device.

[0288] In some embodiments, the first reporting value may be determined by any of the following methods:

[0289] Use the second mapping value in the second mapping values that is greater than or equal to the first mapping value as the first reporting value;

[0290] Use the second mapping value in the second mapping values that is less than or equal to the first mapping value as the first reporting value.

[0291] Step S306: The terminal device determines a second reporting value corresponding to each RACH resource set in the first RACH resource set.

[0292] In some embodiments, the second reporting value corresponding to the RACH resource set may be determined according to a second association relationship. Among them, the second association relationship may include a correspondence between different RACH resource sets and reporting values, and the second association relationship may be predefined.

[0293] Step S307: The terminal device uses the RACH resource sets corresponding to the second reporting values that belong to at least one first reporting value among the multiple second reporting values as the second RACH resource sets.

[0294] In some embodiments, for each second reporting value among the multiple second reporting values, it may be determined whether the second reporting value belongs to at least one first reporting value. If it is determined that the second reporting value belongs to at least one first reporting value, the RACH resource set corresponding to the second reporting value is used as the second RACH resource set.

[0295] Step S308: The terminal device determines the second information according to the fourth information corresponding to at least one second RACH resource set.

[0296] In some embodiments, the second information may be determined by any of the following methods:

[0297] Use the minimum value among the fourth information corresponding to at least one second RACH resource set as the second information;

[0298] Use the maximum value among the fourth information corresponding to at least one second RACH resource set as the second information.

[0299] For example, if the fourth information is RSRP, the minimum RSRP among the RSRPs corresponding to at least one second RACH resource set can be determined and used as the second information; if the fourth information is CQI, the minimum CQI among the CQIs corresponding to at least one second RACH resource set can be determined and used as the second information; if the fourth information is the number of repetitions, the minimum number of repetitions among the numbers of repetitions corresponding to at least one second RACH resource set can be determined and used as the second information; if the fourth information includes RSRP and CQI, the average value of the RSRP and CQI corresponding to at least one second RACH resource set can be determined, and the RSRP and CQI corresponding to the minimum average value can be used as the second information.

[0300] It should be noted that the above methods for determining the second information are for illustrative purposes, and the implementation methods of the embodiments of the present disclosure are not limited thereto.

[0301] Step S309: The terminal device reports the second information to the network device through Msg1 or MsgA.

[0302] For the optional implementation methods of this step S309, reference can be made to Figure 2 the optional implementation methods of step S204 in Figure 2 and other related parts in the involved embodiments, which will not be elaborated here.

[0316] For the optional implementation manner of this step S406, reference can be made to Figure 3 the optional implementation manner of step S306 in Figure 3 Other related parts in the embodiments involved are not elaborated here.

[0317] Step S407: The terminal device determines that none of the multiple second reporting values belong to at least one first reporting value.

[0318] For example, if it is determined that none of the second reporting values are included in at least one first reporting value, it can be determined that none of the multiple second reporting values belong to at least one first reporting value.

[0319] Step S408: The terminal device determines second information based on the multiple second reporting values and at least one first reporting value.

[0320] In some embodiments, the second information can be determined by at least one of the following methods:

[0321] Taking the minimum value of the third reporting value as the second information, where the third reporting value includes the second reporting values greater than the fourth reporting value among the multiple second reporting values, and the fourth reporting value is the maximum value among at least one first reporting value;

[0322] Taking the maximum value of the fifth reporting value as the second information, where the fifth reporting value includes the second reporting values less than the sixth reporting value among the multiple second reporting values, and the sixth reporting value is the minimum value among at least one first reporting value.

[0323] In one implementation manner, the maximum value among at least one first reporting value can be determined to obtain the fourth reporting value, the second reporting values greater than the fourth reporting value are determined from the multiple second reporting values to obtain the third reporting value, and the minimum value of the third reporting value is taken as the second information. For example, if at least one first reporting value includes 5, 6, 7, 8, and the second reporting values include 1, 2, 9, 10, then the fourth reporting value can be determined to be 8, the third reporting value includes 9 and 10, and the minimum value of the third reporting value is 9, that is, the second information is 9.

[0324] In another implementation, the minimum value among at least one first reporting value can be determined to obtain the sixth reporting value, the second reporting values less than the sixth reporting value are determined from multiple second reporting values to obtain the fifth reporting value, and the maximum value in the fifth reporting value is used as the second information. For example, if at least one first reporting value includes 5, 6, 7, 8 and the second reporting values include 1, 2, 9, 10, the sixth reporting value can be determined as 5, the fifth reporting value includes 1 and 2, and the maximum value in the fifth reporting value is 2, that is, the second information is 2.

[0325] In another implementation, after determining the minimum value in the third reporting value and the maximum value in the fifth reporting value, one of the minimum value in the third reporting value and the maximum value in the fifth reporting value can be selected as the second information. For example, any one of the minimum value in the third reporting value and the maximum value in the fifth reporting value can be used as the second information, or one of them can be determined as the second information according to the protocol regulations. The embodiments of the present disclosure do not limit this.

[0326] In some embodiments, it is determined that multiple second reporting values are all less than the fourth reporting value, and the maximum value in the fifth reporting value is used as the second information.

[0327] For example, the second information can be determined preferentially through the first implementation method above. If the third reporting value is not obtained, that is, multiple second reporting values are all less than the fourth reporting value (there is no second reporting value greater than the fourth reporting value), the second information is determined through the second implementation method, that is, the fifth reporting value is determined, and the maximum value in the fifth reporting value is used as the second information.

[0328] In some embodiments, it is determined that multiple first reporting values are all greater than the sixth reporting value, and the minimum value in the third reporting value is used as the second information.

[0329] For example, the second information can be determined preferentially through the second implementation method above. If the fifth reporting value is not obtained, that is, multiple second reporting values are all greater than the sixth reporting value (there is no second reporting value less than the sixth reporting value), the second information is determined through the first implementation method, that is, the third reporting value is determined, and the minimum value in the third reporting value is used as the second information.

[0330] Step S409: The terminal device reports the second information to the network device through Msg1 or MsgA.

[0331] The optional implementation of this step S409 can refer to Figure 2 the optional implementation of step S204 in Figure 2 and other related parts in the involved embodiments, which will not be elaborated here.

[0340] Step S504, the terminal device determines the third downlink signal quality according to the first downlink signal quality and the second downlink signal quality.

[0344] Use the second downlink signal quality less than or equal to the first downlink signal quality among the second downlink signal qualities as the third downlink signal quality.

[0345] For example, for each second downlink signal quality, the terminal device may compare the second downlink signal quality with the first downlink signal quality. If the second downlink signal quality is greater than or equal to the second downlink signal quality, the second downlink signal quality may be used as the third downlink signal quality.

[0346] Step S505: The terminal device uses the number of repetitions corresponding to the third downlink signal quality as the first reporting value.

[0347] In some embodiments, the number of repetitions corresponding to the third downlink signal quality may be determined according to a third association relationship, and the third association relationship may include the corresponding relationship between different downlink signal qualities and the number of repetitions.

[0361] For the optional implementation manners of this step S601, reference can be made to Figure 2 the optional implementation manners of step S201 in Figure 2 For other related parts in the embodiments involved, they will not be elaborated here.

[0362] Step S602: The terminal device determines that multiple RACH resource sets in the first configuration information are all the fifth RACH resource sets.

[0363] In some embodiments, the fifth RACH resource set can be used for some features that trigger a terminal device to perform random access, and cannot be used for all features that trigger the terminal device to perform random access.

[0364] For example, if there is no RACH resource set in the first configuration information that can be used for all features that trigger a terminal device to perform random access, it means that multiple RACH resource sets in the first configuration information are all fifth RACH resource sets.

[0365] Step S603: The terminal device determines a sixth RACH resource set from the fifth RACH resource sets according to the priorities of the partial features.

[0366] In some embodiments, the features supported by multiple RACH resource sets in the first configuration information can be sorted. For example, they can be arranged in descending order of priority, and the RACH resource set corresponding to the feature with the highest priority is used as the sixth RACH resource set.

[0367] In some embodiments, the sixth RACH resource set may include at least one RACH resource set.

[0368] Step S604: The terminal device determines the second information according to the fourth information corresponding to the sixth RACH resource set.

[0369] In some embodiments, it is determined that the sixth RACH resource set includes a seventh RACH resource set, and the fourth information corresponding to the seventh RACH resource set is used as the second information. The seventh RACH resource set is the RACH resource set that supports the reporting of the second information.

[0370] In some embodiments, it is determined that the sixth RACH resource set includes multiple seventh RACH resource sets. According to the first downlink signal quality, at least one eighth RACH resource set is determined from the multiple seventh RACH resource sets, and the second information is determined according to the fourth information corresponding to the at least one eighth RACH resource set.

[0371] For example, if the sixth RACH resource set includes a RACH resource set that can support the reporting of the second information, the fourth information corresponding to the RACH resource set is used as the second information; if the sixth RACH resource set includes multiple RACH resource sets that can support the reporting of the second information, one eighth RACH resource set can be selected from the multiple seventh RACH resource sets, and the fourth information corresponding to the eighth RACH resource set is used as the second information.

[0595] The optional implementation manner of this step S1702 can refer to Figure 2 the optional implementation manner of step S204 of Figure 2 Other related parts in the embodiments involved are not described herein again.

[0596] In some embodiments, the above method may include the methods described in the embodiments of the above communication system, terminal device, network device, etc., which are not described herein again.

[0597] In some embodiments, the terminal device initiates a random access procedure, and the terminal device determines whether to report Msg2 / Msg4 / MsgB PDCCH repetition assistance information based on the RACH configuration and / or the downlink signal quality. If reporting, determine the reporting value.

[0598] In some embodiments, the Msg2 / Msg4 / MsgB repetition includes: Msg2 / Msg4 / MsgB PDCCH repetition and / or Msg2 / Msg4 / MsgB PDSCH repetition.

[0600] Downlink signal quality, such as CQI or downlink reference point RSRP;

[0601] The recommended number of repetitions.

[0602] In some embodiments, the terminal device reports the assistance information through Msg1 / MsgA, and the terminal device distinguishes the content of the assistance information through different RACH resources.

[0603] In some embodiments, the terminal device determines one or more Msg2 / Msg4 / MsgB PDCCH repetition auxiliary information reporting values that can be applied to this random access based on the downlink signal quality.

[0604] Embodiment 1. The determination of whether to report auxiliary information based on the RACH configuration includes at least one of the following:

[0605] If there is a CFRA resource configured for this random access, and the CFRA resource only includes RACH resources that support the reporting of auxiliary information;

[0606] If the random access is triggered by an SI request, and the RACH resources for the SI request only include RACH resources that support the reporting of auxiliary information;

[0607] If only RACH resources that support the reporting of auxiliary information are configured on the BWP where the RACH is initiated, it is considered to report the auxiliary information.

[0608] Embodiment 2. The UE determines the content of the auxiliary information report based on the downlink signal quality, including at least one of the following:

[0609] The UE determines the RSRP / CQI / repetition count mapping value based on the RSRP / CQI of the downlink path loss reference point or the RSRP / CQI of the PDCCH. The UE uses all the mapping values supported by the base station that are greater than or equal to or less than or equal to the mapping value as the reporting value;

[0610] The UE compares the RSRP / CQI of the downlink path loss reference point or the RSRP / CQI of the PDCCH with the RSRP / CQI thresholds corresponding to each repetition count. The UE uses all the repetition values supported by the base station where the RSRP / CQI threshold corresponding to the repetition count is greater than or equal to or less than or equal to the measured downlink RSRP / CQI of the UE as the reporting value.

[0611] Embodiment 3. If only one RACH resource set can be used to trigger all features of this random access, the UE directly selects this RACH resource set and uses the repetition count / RSRP / CQI corresponding to this RACH resource set as the reporting value.

[0612] Embodiment 4. If one or more RACH resource sets can be used to trigger all features of this random access, select from these RACH resource sets the one with the supported repetition count / RSRP / CQI located in the set of reporting values selected in Embodiment 2, and the one with the highest / lowest repetition count / RSRP / CQI value as the reporting value.

[0613] Example 4.1, if the number of repetitions / RSRP / CQI supported by none of these RACH resource sets is within the reporting value set selected in Example 2, then handle it in at least one of the following ways:

[0614] (1) Select the minimum value greater than the maximum value of the reporting value set selected in Example 2 from the reporting value sets supported by these RACH resource sets as the reporting value;

[0615] For example: the reporting value set selected in Example 2 is [5, 6, 7, 8], and the reporting value set supported by the RACH resource set is [1, 2, 9, 10], then select 9 as the reporting value.

[0616] (2) Select the maximum value less than the minimum value of the reporting value set selected in Example 2 from the reporting value sets supported by these RACH resource sets as the reporting value;

[0617] For example: the reporting value set selected in Example 2 is [5, 6, 7, 8], and the reporting value set supported by the RACH resource set is [1, 2, 9, 10], then select 2 as the reporting value.

[0618] (3) First, select the minimum value greater than the maximum value of the reporting value set selected in Example 2 from the reporting value sets supported by these RACH resource sets as the reporting value. If not, then select the maximum value less than the minimum value of the reporting value set selected in Example 2 from the reporting value sets supported by these RACH resource sets as the reporting value.

[0619] (4) First, select the maximum value less than the minimum value of the reporting value set selected in Example 2 from the reporting value sets supported by these RACH resource sets as the reporting value. If not, then select the minimum value greater than the maximum value of the reporting value set selected in Example 2 from the reporting value sets supported by these RACH resource sets as the reporting value.

[0620] Example 5, if there is no available RACH resource set that can be used to trigger all features of this random access, but can support some features, the UE selects the resource set with the highest supported feature priority from the available RACH resource sets according to the feature priority, and operates in at least one of the following ways:

[0621] If one or more resource sets are identified, but only one resource set supports the reporting of auxiliary information, then use the number of repetitions / RSRP / CQI corresponding to this RACH resource set as the selected reporting value;

[0622] If multiple resource sets are identified and multiple resource sets support the reporting of auxiliary information, the reporting value is determined in the manner of Embodiment 4.

[0623] Embodiment 6, the RACH resource used by the UE to send the Preamble is the RACH resource corresponding to the final reporting value determined in the above manner.
