Description

Technical Field

[0001] This application relates to the field of wireless technologies, and in particular, to an access method, apparatus, terminal device, and network device. Background Art

[0002] In the 5G NR system, with the evolution of technologies, there is a need to support a Reduced Capability (RedCap) User Equipment (UE). Compared with a general UE (which can also be considered a non-RedCap UE), the RedCap UE aims to reduce the implementation complexity and cost of the terminal. Therefore, the maximum bandwidth supported by the RedCap UE is smaller than that supported by the general UE. For example, when the carrier frequency is below 6 GHz, the maximum bandwidth of a general UE can be 100 MHz, while the maximum bandwidth of the RedCap UE is only 20 MHz; the minimum number of receiving antennas of a general UE is 4 or 2, while the minimum number of receiving antennas of the RedCap UE is 2 or 1.

[0003] Since the receiving capabilities of the general UE and the RedCap UE are different, the earlier the base station (such as the gNB in the 5G NR system) knows whether the UE initiating random access is a general UE or a RedCap UE, the earlier it can perform targeted scheduling, thereby improving the resource utilization rate of the network. The random access process in NR can be divided into two types. One is the four-step random access, that is, the 4-step Random Access Channel (RACH), which is also denoted as the first type of random access (Type-1 random access) in the NR standard. The other is the two-step random access, that is, the 2-step RACH, which is also denoted as the second type of random access (Type-2 random access) in the NR standard.

[0004] The RedCap UE can initiate a 4-step RACH or a 2-step RACH. During the random access process, the RedCap UE can report its terminal type at different stages. Correspondingly, the base station can also identify the terminal type at different stages. However, there is currently no clear solution as to at which specific stages the RedCap UE reports its terminal type (at which stages the base station identifies the terminal type of the UE initiating random access). Summary of the Invention

[0005] The purpose of this application is to provide an access method, apparatus, terminal device, and network device for implementing the reporting of the terminal type of the RedCap UE.

For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0222] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments.

Optionally, the network device broadcasts the RACH configuration information in the broadcast System Information Block 1 (SIB1). Optionally, the 2-step RACH configuration information indicates a set of random access occasion (RO) resources, and a set of physical uplink shared channel PUSCH occasion (PO) resources, and also indicates the mapping relationship between the SSB and the RO, and the mapping relationship between the RO and the PO, etc.;

[0247] Optionally, the predefined manner is a predefined manner, for example, a manner predefined through a standard protocol, and is used to implicitly determine whether to indicate the terminal type during the random access procedure, and / or determine whether to indicate the terminal type in the first pilot, or in the first message, or in both the first pilot and the first message; the indication information is an indication by a network device, such as can be indicated by SIB1. By using this indication information, the network device can indicate whether to indicate the terminal type during the random access procedure, and / or determine whether to indicate the terminal type in the first pilot, or in the first message, or in both the first pilot and the first message.

[0264] In this implementation manner, optionally, the first predefined manner is also: the terminal device determines whether the network device has configured a specific PRACH preamble sequence (such as including a Preamble index) and / or configured a specific random access opportunity (that is, an RO resource) for the terminal device. When it is determined that the network device has configured a specific PRACH preamble sequence and / or configured a specific random access opportunity, it is determined to indicate the terminal type of the terminal device in the first pilot. In this way, during the random access process, the terminal type of the terminal device is indicated in the first pilot.

[0265] Optionally, when the network device does not configure a specific PRACH preamble sequence for the terminal device and there is no specific random access opportunity, it is determined that the terminal type of the terminal device is not indicated in the first pilot.

[0315] When the third indication information indicates that the terminal type is indicated only in the first pilot, the terminal type of the terminal device is indicated in the first pilot; optionally, the terminal type of the terminal device is not indicated in the first message;

[0316] When the third indication information indicates that the terminal type is indicated only in the first message, the terminal type of the terminal device is indicated in the first message; optionally, the terminal type of the terminal device is not indicated in the first pilot;

[0317] When the third indication information indicates that the terminal type is indicated in both the first pilot and the first message, the terminal type of the terminal device is indicated in the first pilot and the first message;

[0318] When the third indication information indicates that the terminal type is not indicated in both the first pilot and the first message, the terminal type of the terminal device is not indicated in the first pilot and the first message.

[0319] Optionally, in an embodiment of the present application, the indication information may further include terminal type reporting related information, such as resources for reporting the terminal type, which may include the logical channel identifier LCID used when the terminal type is reported in the first message Msg3.

[0320] In an embodiment of the present application, in one implementation manner, in step S210, according to the fourth indication information, the terminal device indicates the terminal type of the terminal device during the random access process; and according to the sixth predefined manner, the terminal type of the terminal device is indicated in the first pilot or the first message, specifically:

[0321] According to the fourth indication information, the terminal device indicates the terminal type of the terminal device during the random access process, including:

[0322] When the fourth indication information indicates that the terminal device indicates the terminal type of the terminal device during the random access process, according to the fourth indication information, the terminal type of the terminal device is indicated during the random access process;

[0323] According to the sixth predefined manner, indicating the terminal type of the terminal device in the first pilot or the first message includes:

[0324] When the network device configures a specific preamble sequence for the random access channel PRACH and / or configures a specific random access opportunity for the terminal device, indicate the terminal type of the terminal device in the first pilot; or

[0325] When the network device does not configure a specific preamble sequence for the random access channel PRACH and does not configure a specific random access opportunity for the terminal device, indicate the terminal type of the terminal device in the first message; or, when the first pilot does not indicate the terminal type of the terminal device, indicate the terminal type of the terminal device in the first message.

[0326] Adopting this embodiment, when the fourth indication information indicates that the terminal device indicates the terminal type of the terminal device during the random access process, determine to indicate the terminal type of the terminal device in the first pilot or the first message according to the sixth predefined manner; when the fourth indication information does not indicate that the terminal device indicates the terminal type of the terminal device during the random access process, or indicates that the terminal device does not indicate the terminal type of the terminal device during the random access process, do not indicate the terminal type of the terminal device in the first pilot and the first message.

[0327] In the embodiment of the present application, in step S210, indicating the terminal type of the terminal device in the first pilot includes:

[0328] The first pilot uses the preamble sequence of the PRACH specific to the terminal device; and / or, the first pilot is sent at the random access opportunity specific to the terminal device;

[0331] Specifically, the first pilot uses the preamble sequence of the PRACH specific to the terminal device; and / or, the first pilot is sent at the random access opportunity specific to the terminal device, and the terminal type indicated by the first pilot is the terminal type with reduced capabilities; in addition, carry the logical channel identifier specific to the terminal device in the first message, and the terminal type indicated by the first message is the terminal type with reduced capabilities.

[0332] This application takes the RedCap terminal type as an example. In fact, the terminal type can also be a terminal that is different in other aspects. For example, it can be terminals with different service types, such as the type of small data transmission (SDT) service and the type of non-small data transmission service, or the type of terminal that supports random access network service slicing and the type of terminal that does not support service slicing. Different terminal types can also be the types of terminals that are combinations of multiple different bandwidths, numbers of antennas, and service types.

[0333] It should be noted that in the embodiments of this application, the above-mentioned access method of the specific implementation manner can be applied to both 4-step RACH and 2-step RACH.

[0334] When applied to 4-step RACH, in the above-mentioned various embodiments, the first pilot is the physical random access channel PRACH pilot in the random access process, and the first message is message 3 in the random access process; when applied to 2-step RACH, in the above-mentioned various embodiments, the first pilot is the PRACH pilot in random access process message A, and the first message is the physical uplink shared channel PUSCH in random access process message A.

[0335] Among them, when applied to 4-step RACH and 2-step RACH, the specific implementation manner of indicating the terminal type of the terminal device in the first pilot and / or the first message according to a predefined manner and / or indication information can refer to the above detailed description and will not be elaborated here.

[0336] The following combines specific implementation manners to elaborate in detail on the access method described in the embodiments of this application.

[0337] Embodiment 1

[0338] In this Embodiment 1, taking 4-step RACH as an example, it illustrates how to determine whether to indicate the terminal type of the terminal device in the first pilot (i.e., Msg1) according to a predefined manner, and how to determine whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3) according to a predefined manner.

[0339] In this embodiment, the network device does not need to broadcast and send any dedicated information for indicating the terminal device to report terminal indication information. The terminal device can determine the stage of reporting the terminal type according to a predefined manner, the RACH configuration information of the terminal device, and / or the specific initial uplink BWP configuration information configured for the terminal device, that is, determine whether to indicate the terminal type of the terminal device in Msg1 or in Msg3.

[0340] In this application, "reported terminal type", "indicated terminal type", and "identified terminal type" have similar meanings. Essentially, they all mean that the terminal device enables the network device to identify which type of terminal device it belongs to through specific transmission methods / content. Without special instructions, they can be not distinguished.

[0341] In the first embodiment, the first implementation manner is adopted. According to the first predefined manner, it is determined whether to indicate the terminal type of the terminal device in the first pilot. That is, when the network device configures a specific random access channel PRACH preamble sequence and / or configures a specific random access opportunity for the terminal device, the terminal type of the terminal device is indicated in the first pilot.

[0342] Generally, the network device (such as a gNB) broadcasts and sends random access resource configuration information for ordinary UEs, indicating the RO resources and preamble sets used by ordinary UEs. RedCap UEs and ordinary UEs can share the use of RO resources and preamble index sets. However, the gNB can also configure RedCap UE-specific RO resources for RedCap UEs and / or configure a specific preamble index set for RedCap UEs. For example, the gNB can broadcast and send RedCap UE-specific random access resource configuration information, and the RACH resource configuration information indicates at least one of the RedCap UE-specific RO resources or the RedCap UE-specific preamble set.

[0343] When the gNB broadcasts and sends RedCap UE-specific RACH resource configuration information, the RedCap UE should initiate random access using the RedCap UE-specific RO and / or the RedCap UE-specific preamble index. Correspondingly, when the gNB receives the preamble sent by the UE in the RedCap UE-specific RO, or the gNB detects that the preamble index belongs to the RedCap UE-specific preamble index, it can determine that the UE initiating the random access is a RedCap UE, thus completing the identification of the RedCap UE.

[0344] Therefore, a feasible method for determining whether to indicate the terminal type in Msg1 is to determine whether to indicate the terminal type in Msg1 according to whether the gNB has configured RedCap UE-specific RO resources and / or preamble indexes. If the gNB has configured RedCap UE-specific RO resources and / or preamble indexes, the terminal type is indicated in Msg1; otherwise, it is not indicated in Msg1.

[0345] The specific implementation process of adopting this embodiment is as follows Figure 5 as shown, including:

[0346] S510, determine whether the network device configures a specific preamble sequence for the random access channel PRACH and / or configures a specific random access opportunity for the terminal device. If the determination result is yes, execute step S520; if the determination result is no, execute step S530;

[0347] S520, indicate the terminal type of the terminal device in Msg1;

[0348] S530, do not indicate the terminal type of the terminal device in Msg1.

[0349] Adopting this embodiment, by determining in a predefined manner whether to indicate the terminal type of the terminal device in Msg1, the indication overhead of whether the gNB indicates the UE to perform terminal type indication in the Msg1 transmission stage can be reduced.

[0350] In the first embodiment, the second implementation manner is adopted to determine whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3) according to the second predefined manner.

[0351] Specifically, indicating the terminal type of the terminal device in the first message according to the second predefined manner includes at least one of the following:

[0352] In the case where the first pilot does not indicate the terminal type of the terminal device, indicate the terminal type of the terminal device in the first message;

[0353] In the case where the network device does not configure a specific preamble sequence for the random access channel PRACH and does not configure a specific random access opportunity for the terminal device, indicate the terminal type of the terminal device in the first message;

[0354] In the case where the network device configures a specific initial uplink bandwidth part BWP for the terminal device, indicate the terminal type of the terminal device in the first message;

[0355] In the case where the network device does not configure a specific preamble sequence for the random access channel PRACH and does not configure a specific random access opportunity, and configures a specific initial uplink bandwidth part BWP for the terminal device, indicate the terminal type of the terminal device in the first message;

[0356] Without considering whether the first pilot indicates the terminal type of the terminal device, indicate the terminal type of the terminal device in the first message. Specifically, different from Msg1, the transmission resources of Msg3 are dynamically scheduled by the information in Msg2. Among them, determining whether to indicate the terminal type of the terminal device in the Msg3 stage through a second predefined method includes the following methods:

[0357] Method 1: Determine whether to report in the Msg3 stage according to whether to report in the Msg1 stage;

[0358] For the purpose of identifying a RedCap UE, generally, it is only necessary to identify in one of the Msg1 stage and the Msg3 stage. Therefore, a feasible method is that if the RedCap UE does not report the terminal type in the Msg1 stage, the RedCap UE determines to report in the Msg3 stage; conversely, if it reports in the Msg1 stage, it does not report in the Msg3 stage.

[0359] If combined with the aforementioned method of determining the terminal type of the terminal device reported in Msg1 according to the first predefined method, it can also be determined whether to report in the Msg3 stage according to whether the gNB configures RedCap-specific RO resources and / or Preamble indexes - if the gNB configures RedCap-specific RO resources and / or Preamble indexes, it does not report in the Msg3 stage (and reports in the Msg1 stage), and conversely, it reports in the Msg3 stage (and does not report in the Msg1 stage).

[0360] The specific implementation process of adopting this implementation method can refer to Figure 6 as shown, including:

[0361] S610, determine whether the network device configures a specific random access channel PRACH preamble sequence and / or a specific random access timing for the terminal device. If the determination result is yes, execute step S620; if the determination result is no, execute step S630;

[0362] S620, do not indicate the terminal type of the terminal device in Msg3;

[0363] S630, indicate the terminal type of the terminal device in Msg3.

[0364] Method 2: Determine whether to indicate the terminal type of the terminal device in Msg3 according to whether the gNB configures a RedCap-specific initial uplink BWP;

[0365] Generally, the gNB broadcasts the configuration information of the initial downlink BWP and the initial uplink BWP used by ordinary UEs, and the ordinary UEs will complete the random access process in the initial downlink BWP and the initial uplink BWP, including receiving Msg2 and Msg4 in the initial downlink BWP, and sending Msg3 in the initial uplink BWP. The RedCap UE and the ordinary UE can share the use of the initial downlink BWP and the initial uplink BWP. However, the gNB can also configure the RedCap UE-specific initial downlink BWP and / or the initial uplink BWP for the RedCap UE. For example, the gNB can broadcast the configuration information of the RedCap UE-specific initial downlink BWP and / or the initial uplink BWP, which are respectively used to indicate the frequency range of the RedCap UE-specific initial downlink BWP and / or the frequency range of the RedCap UE-specific initial uplink BWP.

[0366] When the gNB broadcasts the RedCap UE-specific initial downlink BWP, the RedCap UE will receive Msg2 in the RedCap UE-specific initial downlink BWP and obtain the scheduling indication information of Msg3; when the gNB broadcasts the RedCap UE-specific initial uplink BWP, the RedCap UE will send Msg3 in the RedCap UE-specific initial uplink BWP. In short, if the RedCap UE and the ordinary UE share the initial downlink BWP and the initial uplink BWP, it means that the gNB believes that it is not necessary to identify the RedCap UE in the initial access stage, and it is not necessary to identify the RedCap UE in the Msg3 stage either; otherwise, the terminal type can be reported in the Msg3 stage.

[0367] For the specific implementation process of adopting this implementation manner, reference can be made to Figure 7 as shown, including:

[0368] S710, determine whether the gNB has configured the RedCap UE-specific initial uplink BWP; if the determination result is yes, then execute step S720; if the determination result is no, then execute step S730;

[0369] S720, indicate the terminal type of the terminal device in Msg3;

[0370] S730, do not indicate the terminal type of the terminal device in Msg3.

[0371] Method 3: Determine whether to indicate the terminal type in Msg3 according to whether it is reported in the Msg1 stage and whether the gNB has configured the RedCap UE-specific initial uplink BWP;

[0372] This Method 3 is also the combination of the reporting methods of Method 1 and Method 2. Specifically, if the RedCap UE does not report in the Msg1 phase and the gNB configures a RedCap-specific initial uplink BWP, it is determined to report in the Msg3 phase; conversely, if it reports in the Msg1 phase, or the gNB does not configure a RedCap-specific initial uplink BWP, it is determined not to report in the Msg3 phase.

[0373] The specific implementation process of adopting this implementation method can refer to Figure 8 as shown, including:

[0374] S810, determine whether the gNB configures a specific preamble sequence of the physical random access channel (PRACH) and / or a specific random access opportunity for the RedCap UE; if the determination result is yes, execute step S820; if the determination result is no, execute step S830;

[0375] S820, indicate the terminal type of the terminal device in Msg1 and do not indicate the terminal type of the terminal device in Msg3;

[0376] S830, determine whether the gNB configures a RedCap-specific initial uplink BWP; if the determination result is yes, execute step S840; if the determination result is no, execute step S850;

[0377] S840, do not indicate the terminal type of the terminal device in Msg1 and indicate the terminal type of the terminal device in Msg3;

[0378] S850, do not indicate the terminal type of the terminal device in Msg1 and do not indicate the terminal type of the terminal device in Msg3.

[0379] Method 4: Without considering whether the first pilot indicates the terminal type of the terminal device, always indicate the terminal type of the terminal device in Msg3.

[0380] Since the method of indicating the terminal type through Msg3 can be indicated by a specific state of the Logical Channel ID (LCID) carried in the Msg3 message. For example, the type of the UE is indicated as a RedCap UE through at least one state in the LCID. In a communication system, the LCID is a high-layer information, that is, information related to the Packet Data Convergence Protocol (PDCP) layer or the Media Access Control (MAC) layer. And sending Msg1, Msg3, etc. are physical layer behaviors. Cross-layer interaction (such as determining the LCID of Msg3 based on whether the UE type is identified in the Msg1 stage) may increase the complexity of the UE and the gNB, which is particularly disadvantageous for RedCap UEs to reduce costs and complexity.

[0381] Therefore, in an embodiment of the present application, a feasible method is that the RedCap UE always indicates the terminal type of the terminal device in Msg3 (the first message) regardless of whether the terminal type of the terminal device is indicated in Msg1 (the first pilot).

[0382] In an embodiment of the present application, the method of determining whether to indicate the terminal type of the terminal device in Msg3 is combined with the method of determining whether to indicate the terminal type of the terminal device in Msg1, and the formed implementation process can be Figure 9 as shown, including:

[0383] S910, determine whether the gNB has configured a specific random access channel PRACH preamble sequence and / or configured a specific random access opportunity for the RedCap UE; if the determination result is yes, then execute step S920; if the determination result is no, then execute step S930;

[0384] S920, indicate the terminal type of the terminal device in Msg1 and indicate the terminal type of the terminal device in Msg3;

[0385] S930, do not indicate the terminal type of the terminal device in Msg1, but indicate the terminal type of the terminal device in Msg3.

[0386] Adopting this implementation method, the RedCap UE always indicates the terminal type of the terminal device in Msg3 regardless of whether the terminal type of the terminal device is indicated in Msg1. The RedCap UE can reduce cross-layer interaction when determining in which stage to indicate the terminal type, thereby reducing complexity.

[0387] Furthermore, by adopting the method described in this embodiment, without the need to introduce any "indication information", RedCap UEs can determine whether to indicate the UE type during the Msg1 transmission phase and / or whether to indicate the UE type during the Msg3 transmission phase. This not only realizes the identification of the UE type but also reduces the indication overhead.

[0388] Embodiment 2

[0389] In this Embodiment 2, taking the 4-step RACH as an example, it is illustrated how to determine whether to indicate the terminal type of the terminal device in the first pilot (i.e., Msg1) according to a predefined manner, and how to determine whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3) according to the indication method.

[0390] In this embodiment, from the perspective of the terminal device, whether to indicate the terminal type of the terminal device in Msg1 is determined according to an implicit manner, while whether to indicate the terminal type of the terminal device in Msg3 is determined through indication information.

[0391] Among them, to determine whether to indicate the terminal type of the terminal device in Msg1 according to a predefined manner, the detailed description method in Embodiment 1 above can be referred to and will not be elaborated here.

[0392] Furthermore, in this embodiment, whether the RedCap UE "indicates the UE type in Msg3" is determined according to the indication information of the gNB.

[0393] For example, the gNB can broadcast the indication information in the system message, such as including this indication information in the System Information Block 1 (SIB1). After receiving this indication information, the RedCap UE determines whether to indicate the UE type in Msg3 according to this indication information; optionally, it can further determine how to indicate the UE type in Msg3.

[0394] Specifically, a possible method is to stipulate an LCID used by the RedCap UE to indicate the UE type through a predefined manner, such as the value of the LCID that the protocol stipulates the RedCap UE uses in Msg3. By adopting this method, the indication information only needs to indicate "whether the RedCap UE indicates the UE type in Msg3".

[0395] For example, the indication information only includes 1-bit information, and the values 0 or 1 of this information respectively indicate "it is necessary to indicate the UE type in Msg3" and "it is not necessary to indicate the UE type in Msg3"; or it includes an information that can take two states, and the two states that this information can take respectively indicate "it is necessary to indicate the UE type in Msg3" and "it is not necessary to indicate the UE type in Msg3"; or, the indication information only indicates "it is necessary to indicate the UE type in Msg3", and if the SIB1 does not include the indication information, it means "it is not necessary to indicate the UE type in Msg3".

[0396] Specifically, another possible method is that the LCID used by the RedCap UE to indicate the UE type is not a single LCID predefined by the protocol, but can be multiple LCIDs predefined by the protocol, or the protocol does not perform predefined. In this case, the indication information not only indicates whether the RedCap UE needs to indicate the UE type in Msg3, but also needs to indicate the LCID used by the RedCap UE when indicating the UE type.

[0397] For example, if the protocol predefines N LCIDs (LCID_1, LCID_2,..., LCID_N) for indicating the reported UE type, then the indication information indicates one of multiple states representing 'LCID_1', 'LCID_2',..., 'LCID_N'. When indicating 'LCID_X', the RedCap UE indicates the UE type in Msg3 by reporting the Xth LCID, and when the indication information indicates 'do not indicate the UE type' or the SIB1 does not include the indication information, it means "it is not necessary to indicate the UE type in Msg3".

[0398] For example, if the protocol does not predefine any LCIDs, then the indication information indicates that when the RedCap UE indicates the UE type in Msg3, it can indicate the value of the LCID specifically used by the RedCap UE. When indicating the value of the LCID used by the RedCap UE, the RedCap UE indicates the UE type in Msg3 by reporting the indicated LCID. And when the indication information indicates 'do not indicate the UE type' or the SIB1 does not include the indication information, it means "it is not necessary to indicate the UE type in Msg3".

[0399] In summary, through the method described in this embodiment, it is not necessary to introduce "indication information" for the indication of the terminal type in Msg1, while for the indication of the terminal type in Msg3, it is indicated whether it is necessary to report through "indication information", and optionally, it also includes the relevant indication information of the Msg3 reported LCID, achieving a compromise between the indication overhead and the indication flexibility.

[0400] Embodiment Three

[0401] In the third embodiment, taking the 4-step RACH as an example, it is described how to determine whether to indicate the terminal type of the terminal device in the first pilot (i.e., Msg1) according to the indication information, and how to determine whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3) according to a predefined method.

[0402] In this embodiment, determining whether to indicate the UE type in Msg1 for a RedCap UE is determined according to the indication information of the gNB.

[0403] For example, the gNB may broadcast the indication information in the system message, such as including this indication information in the System Information Block 1 (SIB1). After receiving this information, the RedCap UE determines whether to indicate the UE type in Msg1 according to this indication information; optionally, it may further determine how to indicate the UE type in Msg1.

[0404] Specifically, one possible method is that the indication information only needs to indicate whether a RedCap UE indicates the UE type in Msg1. When the RedCap UE determines according to the indication that it needs to indicate the UE type in Msg1, it uses the RO resources and / or Preamble index specific to the RedCap UE to initiate random access. Which specific RO resources and / or Preamble index of the RedCap UE to use can be predefined or determined according to the actual configuration of the gNB for the RO resources and / or Preamble index specific to the RedCap UE.

[0405] For example, the indication information only includes 1-bit information, and the values 0 or 1 of this information respectively indicate "need to indicate the UE type in Msg1" and "do not need to indicate the UE type in Msg1"; or it includes an information with two available states, and the two available states of this information respectively indicate "need to indicate the UE type in Msg1" and "do not need to indicate the UE type in Msg1"; or, the indication information only indicates "need to indicate the UE type in Msg1", and if the indication information is not included in SIB1, it means "do not need to indicate the UE type in Msg1".

[0406] Specifically, another possible method is that the indication information not only indicates whether a RedCap UE indicates the UE type in Msg1, but also needs to indicate the specific way for the RedCap UE to indicate the UE type in Msg1.

[0407] For example, the indication information indicates which one of the following three methods the RedCap UE should specifically use to initiate random access: initiate random access through the RO resource specific to the RedCap UE, initiate random access using the preamble specific to the RedCap UE, and initiate random access through the RO resource specific to the RedCap UE and using the preamble specific to the RedCap UE. When the indication information indicates 'not report' or the SIB1 does not include the indication information, it means that "there is no need to indicate the UE type in Msg1".

[0408] In this embodiment, for the method of determining whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3) according to a predefined method, this method is the same as the method of determining whether to indicate the terminal type of the terminal device in Msg3 in Embodiment 1, and will not be elaborated here.

[0409] In summary, through the method in this embodiment, for the indication of the UE type in Msg3, there is no need to introduce "indication information", and for the indication of the UE type in Msg1, it is indicated whether to report through "indication information", and optionally, it also includes the indication method of indicating the UE type in Msg1 (specifically, one of initiating random access through the RO resource specific to the RedCap UE, initiating random access using the preamble specific to the RedCap UE, and through the RO resource specific to the RedCap UE and using the preamble index specific to the RedCap UE), achieving a compromise between indication overhead and indication flexibility.

[0410] Embodiment 4

[0411] In this Embodiment 4, taking the 4-step RACH as an example, it illustrates how to determine whether to indicate the terminal type of the terminal device in the first pilot (i.e., Msg1) according to the indication information, and how to determine whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3) according to the indication information.

[0412] In this embodiment of the present application, whether the UE indicates the terminal type in Msg1 and whether it indicates the terminal type in Msg3 are both indicated by the indication information. Specifically, for the method of the indication information indicating to report the terminal type in Msg3, reference can be made to the detailed description in Embodiment 2, and for the method of the indication information indicating to report the terminal type in Msg1, reference can be made to the detailed description in Embodiment 3, which will not be elaborated here.

[0413] For example, the indication information may indicate one of the following multiple pieces of candidate information: (1) the terminal indicates the terminal type in Msg1, (2) the terminal indicates the terminal type in Msg3, (3) the terminal indicates the terminal type in both Msg1 and Msg3. The terminal device then indicates the terminal type in Msg1 and / or Msg3 according to the indication of the indication information. Optionally, the indication information may also indicate the candidate information (4) the terminal does not indicate the terminal type in both Msg1 and Msg3, then the terminal device does not indicate the terminal type in both Msg1 and Msg3, or when the network device does not send the indication information, the terminal does not indicate the terminal type in both Msg1 and Msg3.

[0414] In this embodiment, an indication information may be used to indicate whether the RedCap UE reports the terminal type in Msg1 and whether it reports the terminal type in Msg3; furthermore, it may also indicate the specific indication method for indicating the terminal type in Msg1 and / or the specific indication method for indicating the terminal type in Msg3.

[0415] Through the method in this embodiment, it is possible to clearly indicate whether the RedCap UE reports the UE type in the initial access stage, specifically in which stage it reports the UE type, and how to report the UE type. Therefore, the gNB can clearly and unambiguously require the RedCap UE to report the UE type at the appropriate stage according to the requirements, achieving the maximum flexibility. For example, although the gNB configures specific RO and / or Preamble for the RedCap UE to be used for reporting the UE type in Msg1, when the uplink load of the cell is heavy, the gNB can indicate that the RedCap UE reports the UE type only in the Msg3 stage, thereby reducing the occupation of uplink resources and achieving the effect of timely adjustment.

[0416] Embodiment 5

[0417] In the fourth embodiment, taking the 4-step RACH as an example, it is described that according to the indication information, the terminal device determines whether to indicate the terminal type of the terminal device during the random access process, and determines to indicate the terminal type of the terminal device in the first pilot (Msg1) or the first message (Msg3) according to a predefined manner.

[0418] On the one hand, according to the indication information, it is determined whether it is necessary to indicate the terminal type of the terminal device during the random access process.

[0419] Among them, the indication information only indicates as a whole whether the UE needs to indicate the terminal type during the random access process, without specifically indicating whether the terminal reports in Msg1 or Msg3.

[0420] For example, the indication information only includes 1-bit information, and the values 0 or 1 of this information respectively indicate "it is necessary to indicate the terminal type during the random access process" and "it is not necessary to indicate the terminal type during the random access process"; or it includes an information that can take two states, and the two states that this information can take respectively indicate "it is necessary to indicate the terminal type during the random access process" and "it is not necessary to indicate the terminal type during the random access process"; or, the indication information only indicates "it is necessary to indicate the terminal type during the random access process", and if the SIB1 does not include the indication information, it means "it is not necessary to indicate the terminal type during the random access process".

[0421] On the other hand, when the indication information indicates that the terminal type needs to be reported during the random access process, in a predefined manner, it is determined to indicate the terminal type in Msg1 or in Msg3.

[0422] Among them, the way to determine whether to indicate the terminal type in Msg1 and whether to indicate the terminal type in Msg3 in a predefined manner can refer to the above-mentioned Embodiment 1, that is, when the indication information indicates that it is necessary to indicate the terminal type during the random access process, according to whether the gNB is configured with RedCap UE-specific RO resources and / or Preamble index, it is determined whether to indicate the terminal type in Msg1 and whether to indicate the terminal type in Msg3 - if the gNB is configured with RedCap UE-specific RO resources and / or Preamble index, the terminal type is indicated in Msg1 and not in Msg3, otherwise, the terminal type is indicated in Msg3 and not in Msg1.

[0423] Specifically, for the specific implementation process of adopting this embodiment, reference can be made to Figure 10 as shown, including:

[0424] S1010, according to the indication information, judge whether it is necessary to indicate the terminal type of the RedCap UE during the random access process; if the judgment result is no, then execute step S1020; if the judgment result is yes, then execute step S1030;

[0425] S1020, do not indicate the terminal type of the terminal device in Msg1 and do not indicate the terminal type of the terminal device in Msg3;

[0426] S1030, judge whether the gNB is configured with a specific random access channel PRACH preamble sequence and / or a specific random access occasion for the RedCap UE; when the judgment result is yes, then execute step S1040; when the judgment result is no, then execute step S1050;

[0427] S1040, indicate the terminal type of the terminal device in Msg1 and do not indicate the terminal type of the terminal device in Msg3;

[0428] S1050, do not indicate the terminal type of the terminal device in Msg1 and indicate the terminal type of the terminal device in Msg3.

[0429] By using the method described in this embodiment, it can be clearly indicated whether the RedCap UE reports the UE type in the initial access stage and specifically in which stage it reports the UE type. Therefore, the gNB can clearly and unambiguously require the RedCap UE to report the UE type at an appropriate stage according to the requirements, achieving a compromise between flexibility and indication overhead.

[0430] It should be noted that in the embodiments of this application, taking the access methods described in Embodiments 1 to 5 as examples of identifying ordinary UEs and RedCap UEs, the methods described in the embodiments of this application are described in detail. However, the access methods described in this application are not limited to being applied to the identification of terminal types of RedCap UEs, but can also be used for the identification of UEs in other fields, such as identifying the service types of UEs (different RAN slicing, etc.).

[0431] In addition, in the embodiments of this application, the access methods described in Embodiments 1 to are described by taking the 4-step RACH as an example. However, the methods described in this embodiment can also be applied to the 2-step RACH. When applied to the 2-step RACH, the above-mentioned Msg1 can be replaced by the PRACH pilot in Message A, and Msg3 can be replaced by the PUSCH in Message A. The specific implementation manner is the same as that of the above embodiment and will not be described in detail here.
