Description

[0001] The present disclosure is a divisional application of the invention patent with the invention name: Access method, device, terminal equipment and network equipment, application number: 202111162480.8, and the application date of the parent case is September 30, 2021. Technical Field

[0002] The present application relates to the field of wireless technology, and in particular to an access method, apparatus, terminal equipment, and network equipment. Background Art

[0003] In 5G NR systems, as technology evolves, it is necessary to support a type of terminal UE with reduced capability (RedCap). Compared with ordinary UE (also considered non-RedCap UE), RedCap UE aims to reduce the implementation complexity and cost of the terminal. Therefore, the maximum bandwidth supported by RedCap UE will be smaller than the maximum bandwidth supported by ordinary UE. For example, when the carrier frequency is below 6GHz, the maximum bandwidth of ordinary UE can be 100MHz, while the maximum bandwidth of RedCap UE is only 20MHz; the minimum number of receiving antennas for ordinary UE is 4 or 2, while the minimum number of receiving antennas for RedCap UE is 2 or 1.

[0004] Because standard UEs and RedCap UEs have different receiving capabilities, the sooner a base station (such as a gNB in ​​a 5G NR system) determines whether the UE initiating random access is a standard UE or a RedCap UE, the sooner it can perform targeted scheduling, thereby improving network resource utilization. The random access process in NR can be divided into two types: four-step random access, also known as the 4-step Random Access Channel (RACH), also referred to as Type-1 random access in the NR standard, and two-step random access, also known as 2-step RACH, also referred to as Type-2 random access in the NR standard.

[0005] A RedCap UE can initiate either a 4-step RACH or a 2-step RACH. During random access, a RedCap UE can report its terminal type at different stages, and the base station can identify the terminal type accordingly. However, there is currently no clear solution for the specific stages in which a RedCap UE reports its terminal type (and the stages in which the base station identifies the terminal type initiating random access). Summary of the Invention

[0006] The purpose of this application is to provide an access method, apparatus, terminal equipment and network equipment for implementing terminal type reporting of RedCap UE.

[0222] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. 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 indicates that the associated objects are in an "or" relationship.

[0223] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0224] like Figure 1 FIG2 is a schematic diagram of an embodiment of a system for applying the access method described in an embodiment of the present application. The system includes a terminal device 10 and a network device 20.

[0225] The access method described in this application can be applied to a variety of systems, especially 5G systems, and is particularly emphasized to be applied to systems that need to identify two different types of terminal devices during the initial access phase. Figure 1 Taking the illustrated scenario as an example, within this system, multiple terminal devices, including UE1 and UE2, initiate random access requests to network device 20, requesting wireless network connection services. Network device 20 receives random access requests from at least one terminal device and provides wireless services to that terminal device. Data is exchanged and transmitted between network device 20 and UE1 and UE2 via wireless communication.

[0226] For example, the system to which the access method described in the embodiment of the present application is applicable may be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, and the like. These various systems all include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), and the like.

[0227] The terminal device involved in the embodiments of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called User Equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device.

[0228] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or may be named otherwise. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0229] In order to solve the problem that the existing technology does not have a clear reporting time for the terminal type reporting of RedCap UE, an embodiment of the present application provides an access method, which can determine the timing when the terminal device indicates the terminal type to the network device through a predefined method and / or indication information, so as to clarify the reporting timing of the RedCap UE reporting the terminal type.

[0230] like Figure 2 FIG. 1 is a flow chart of an access method according to one embodiment of the present application. The access method according to this embodiment, applied to a terminal device, includes:

[0232] Wherein, according to a predefined method and / or indication information, the terminal type of the terminal device is indicated in the first pilot and / or the first message.

Optionally, the network device broadcasts the RACH configuration information in the broadcast System Information Block 1 (SIB1). Optionally, the 4-step RACH configuration information indicates a set of random access opportunity (RACH Occasion, RO) resources and a mapping relationship between synchronization signal blocks (SSBs) and ROs;

[0241] Figure 4 The following are the steps for implementing a two-step random access (also referred to as 2-step RACH) process using the access method described in this application, including:

[0242] S410: The network device sends RACH configuration information to the terminal device. 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 opportunity (RACH Occasion, RO) resources and a set of physical uplink shared channel (PUSCH Occasion, PO) resources, and also indicates a mapping relationship between SSB and RO, and a mapping relationship between RO and PO, etc.

[0243] S420, the terminal device sends a message A (also expressed as MsgA) to the network device, where the MsgA includes a PRACH pilot and a PUSCH;

[0244] S430: The network device sends a message B (also expressed as MsgB) to the terminal device, which may also be called a conflict resolution message.

[0246] The random access process is a two-step random access process, the first pilot is a PRACH pilot in a random access process message A, and the first message is a physical uplink shared channel PUSCH in the random access process message A.

[0247] Using the access method described in the embodiment of the present application, whether the terminal device uses 4-step RACH or 2-step RACH, the terminal type of the terminal device can be indicated in the first pilot and / or the first message according to the predefined method and / or indication information to clarify the reporting timing of the terminal type.

[0248] Optionally, the predefined method is a predefined method, for example, a method predefined by a standard protocol, and is used to determine in an implicit manner whether it is necessary to indicate the terminal type during the random access process, and / or determine whether to indicate the terminal type in the first pilot or in the first message, or to indicate the terminal type in both the first pilot and the first message; the indication information is a network device indication, such as can be indicated by SIB1, and the indication information can be used to indicate whether it is necessary to indicate the terminal type during the random access process, and / or determine whether to indicate the terminal type in the first pilot or in the first message, or to indicate the terminal type in both the first pilot and the first message.

[0249] In the embodiment of the present application, optionally, in step S210, 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 includes at least one of the following:

[0250] Indicating a terminal type of the terminal device in the first pilot according to a first predefined manner;

[0251] Indicating a terminal type of the terminal device in the first message according to a second predefined manner;

[0252] Indicating a terminal type of the terminal device in the first pilot and the first message according to a third predefined manner;

[0257] In the embodiment of the present application, through the above implementation, at least one of the following methods can be used to determine whether to indicate the terminal type in the first pilot and whether to indicate the terminal type in the first message. According to the determination result, during the random access process, when sending the first pilot and the first message, the terminal type of the terminal device is indicated in the first pilot and / or the first message:

[0263] In one implementation manner, optionally, indicating the terminal type of the terminal device in the first pilot according to a first predefined manner includes:

[0264] In a case where 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.

[0265] In this embodiment, optionally, the first predefined method is: the terminal device determines whether the network device has configured a specific PRACH preamble sequence (such as including a Preamble index) and / or a specific random access opportunity (that is, an RO resource) for the terminal device, and when it is determined that the network device has configured a specific PRACH preamble sequence and / or a specific random access opportunity, determines to indicate the terminal type of the terminal device in the first pilot, so that during the random access process, the terminal type of the terminal device is indicated in the first pilot. Optionally, when the terminal type of the terminal device is indicated in the first pilot, the terminal type of the terminal device is not indicated in the first message.

[0266] 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 not to indicate the terminal type of the terminal device in the first pilot. Therefore, during the random access process, the terminal type of the terminal device is not indicated in the first pilot.

[0267] In another implementation manner, optionally, according to a second predefined manner, indicating the terminal type of the terminal device in the first message includes at least one of the following:

[0270] In a case where the network device configures a specific initial uplink bandwidth part BWP for the terminal device, indicating the terminal type of the terminal device in the first message;

[0271] In a case where the network device does not configure a specific random access channel PRACH preamble sequence and does not configure a specific random access opportunity for the terminal device, and configures a specific initial uplink bandwidth part BWP for the terminal device, indicating the terminal type of the terminal device in the first message;

[0272] Regardless of whether the first pilot indicates the terminal type of the terminal device, the terminal type of the terminal device is indicated in the first message.

[0273] Using this implementation, whether it is necessary to indicate the terminal type of the terminal device in the first message is determined according to a predetermined second predefined method. When it is determined that the terminal type of the terminal device needs to be indicated, the terminal type of the terminal device is indicated in the first message during the random access process.

[0274] In this implementation, optionally, one of the ways, the second predefined way includes:

[0275] Whether the terminal type of the terminal device is indicated in the first message is determined according to whether the terminal type of the terminal device is indicated in the first pilot.

[0277] Optionally, in another implementation manner, the second predefined manner includes:

[0278] Whether to indicate the terminal type of the terminal device in the first message is determined according to whether the network device configures a specific random access channel PRACH preamble sequence and / or a specific random access opportunity for the terminal device.

[0279] Specifically, when the network device does not configure a specific random access channel PRACH preamble sequence for the terminal device and does not configure a specific random access timing, the terminal type of the terminal device is indicated in the first message; optionally, when the network device configures a specific random access channel PRACH preamble sequence and / or configures a specific random access timing for the terminal device, the terminal type of the terminal device is indicated in the first pilot, but the terminal type of the terminal device is not indicated in the first message.

[0280] Optionally, in another embodiment, the second predefined manner includes:

[0281] Whether to indicate the terminal type in the first message is determined according to whether the network device has configured a specific initial uplink bandwidth part BWP for the terminal device.

[0282] Specifically, when the network device configures a specific initial uplink bandwidth part BWP for the terminal device, the terminal type of the terminal device is indicated in the first message; optionally, the terminal type of the terminal device may not be indicated in the first pilot;

[0283] Optionally, when the network device does not configure a specific initial uplink bandwidth part BWP for the terminal, the terminal type of the terminal device is not indicated in the first message; optionally, the terminal type of the terminal device may also not be indicated in the first pilot.

[0284] Optionally, in another embodiment, the second predefined manner includes:

[0285] Whether to indicate the terminal type of the terminal device in the first message is determined according to whether the network device configures a specific random access channel PRACH preamble sequence and / or a specific random access opportunity, as well as a specific initial uplink bandwidth part for the terminal device.

[0286] Specifically, when the network device does not configure a specific random access channel PRACH preamble sequence for the terminal device and does not configure a specific random access timing, and configures a specific initial uplink bandwidth part BWP for the terminal device, 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.

[0288] It should be noted that, since determining whether the network device configures a specific random access channel PRACH preamble sequence and / or a specific random access opportunity for the terminal device may be a predefined method for determining whether the terminal type of the terminal device is indicated in the first pilot, the above embodiment may also be considered to include:

[0289] Whether to indicate the terminal type of the terminal device in the first message is determined based on whether the terminal type of the terminal device is indicated in the first pilot and whether the network device configures a specific initial uplink bandwidth portion for the terminal device. Specifically, if the terminal type of the terminal device is not indicated in the first pilot and the network device configures a specific initial uplink bandwidth portion for the terminal device, the terminal type of the terminal device is indicated in the first message; if the terminal type of the terminal device is indicated in the first pilot or the network device does not configure a specific initial uplink bandwidth portion for the terminal device, the terminal type of the terminal device is not indicated in the first message.

[0295] According to the third predefined manner, one of the above-mentioned implementation modes is adopted, and the terminal type of the terminal device is indicated in both the first pilot and the first message.

[0296] In one embodiment of the present application, in step S210, according to the fourth predefined manner, the terminal type of the terminal device is indicated in the first pilot; and according to the first indication information, when the terminal type of the terminal device is indicated in the first message, specifically:

[0308] In a case where the first pilot does not indicate the terminal type of the terminal device and the network device configures a specific initial uplink bandwidth part BWP for the terminal device, indicating the terminal type of the terminal device in the first message;

[0309] Regardless of whether the first pilot indicates the terminal type of the terminal device, the terminal type of the terminal device is indicated in the first message.

[0310] By adopting this implementation mode, it can be determined whether the terminal type of the terminal device is indicated in the first pilot based on the second indication information; when the second indication information indicates that the terminal type is indicated in the first pilot, the terminal type of the terminal device is indicated in the first pilot; when the second indication information does not indicate that the terminal type is indicated in the first pilot, or indicates that it is not necessary to indicate the terminal type in the first pilot, or the network device does not send the second indication information, the terminal type of the terminal device is not indicated in the first pilot.

[0311] Determining, according to a fifth predefined manner, whether to indicate a terminal type of the terminal device in the first message, wherein in one embodiment, determining whether to indicate the terminal type of the terminal device in the first message according to whether the first pilot indicates the terminal type of the terminal device; wherein, if the first pilot does not indicate the terminal type of the terminal device, the terminal type of the terminal device is indicated in the first message, and if the first pilot indicates the terminal type of the terminal device, the terminal type of the terminal device is not indicated in the first message;

[0312] In another embodiment, whether to indicate the terminal type of the terminal device in the first message is determined based on whether the network device has configured a specific initial uplink bandwidth part BWP for the terminal device; wherein, if the network device has configured a specific initial uplink bandwidth part BWP for the terminal device, the terminal type of the terminal device is indicated in the first message; optionally, if the network device has not configured a specific initial uplink bandwidth part BWP for the terminal device, the terminal type of the terminal device is not indicated in the first message.

[0313] In another embodiment, whether to indicate the terminal type of the terminal device in the first message is determined based on whether the first pilot indicates the terminal type of the terminal device and whether the network device has configured a specific initial uplink bandwidth part BWP for the terminal device; wherein, if the first pilot does not indicate the terminal type of the terminal device and the network device has configured a specific initial uplink bandwidth part BWP for the terminal device, the terminal type of the terminal device is indicated in the first message; optionally, if the first pilot indicates the terminal type of the terminal device or the network device has not configured a specific initial uplink bandwidth part BWP for the terminal device, the terminal type of the terminal device is not indicated in the first message.

[0314] In yet another embodiment, the terminal type of the terminal device is indicated in the first message without considering whether the first pilot indicates the terminal type of the terminal device.

[0315] In one embodiment of the present application, in step S210, indicating the terminal type of the terminal device in the first pilot and / or the first message according to the third indication information includes at least one of the following:

[0316] The third indication information indicates that only when the terminal type is indicated 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;

[0317] The third indication information indicates that only when the terminal type is indicated 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;

[0318] The third indication information indicates that, when the terminal type is indicated in the first pilot and the first message, the terminal type of the terminal device is indicated in the first pilot and the first message;

[0319] The third indication information indicates that, when the terminal type is not indicated in either the first pilot or the first message, the terminal type of the terminal device is not indicated in either the first pilot or the first message.

[0320] 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, such as the logical channel identifier LCID used when the first message Msg3 reports the terminal type.

[0321] In one embodiment of the present application, 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:

[0322] According to the fourth indication information, the terminal device indicates the terminal type of the terminal device during the random access process, including:

[0323] In a case where the fourth indication information indicates that the terminal device indicates the terminal type of the terminal device during the random access process, indicating the terminal type of the terminal device during the random access process according to the fourth indication information;

[0324] According to the sixth predefined manner, indicating the terminal type of the terminal device in the first pilot or the first message includes:

[0325] In a case where the network device configures a specific random access channel PRACH preamble sequence and / or configures a specific random access opportunity for the terminal device, indicating the terminal type of the terminal device in the first pilot; or

[0326] In a case where the network device does not configure a specific random access channel PRACH preamble sequence for the terminal device and does not configure a specific random access timing, the terminal type of the terminal device is indicated in the first message; or, in a case where the first pilot does not indicate the terminal type of the terminal device, the terminal type of the terminal device is indicated in the first message.

[0327] Using this implementation, when the fourth indication information indicates the terminal type of the terminal device indicated by the terminal device during the random access process, the terminal type of the terminal device indicated in the first pilot or the first message is determined according to the sixth predefined method; when the fourth indication information does not indicate the terminal type of the terminal device indicated by 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, the terminal type of the terminal device is not indicated in the first pilot and the first message.

[0328] In the embodiment of the present application, in step S210, indicating the terminal type of the terminal device in the first pilot includes:

[0329] The first pilot uses a PRACH preamble sequence specific to the terminal device; and / or the first pilot is sent in a random access opportunity specific to the terminal device;

[0330] Indicating the terminal type of the terminal device in the first message includes:

[0331] The terminal device-specific logical channel identifier is carried in the first message.

[0332] Specifically, a terminal device-specific PRACH preamble sequence is used through the first pilot; and / or, the first pilot is sent in a random access opportunity specific to the terminal device, and the first pilot is used to indicate that the terminal type of the terminal device is a terminal type with reduced capabilities; in addition, a terminal device-specific logical channel identifier is carried in the first message, and the first message is used to indicate that the terminal type of the terminal device is a terminal type with reduced capabilities.

[0333] 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 a different service type, such as a Small Data Transmission (SDT) service type and a non-small data transmission service type, or a terminal type that supports random access network service slicing and a terminal type that does not support service slicing. Different terminal types can also be terminal types with a combination of multiple different bandwidths, numbers of antennas, and service types.

[0334] It should be noted that, in the embodiment of the present application, the access method of the above specific implementation manner can be applied to both 4-step RACH and 2-step RACH.

[0335] When applied to 4-step RACH, in each of the above implementations, the first pilot is the physical random access channel PRACH pilot in the random access procedure, and the first message is message 3 in the random access procedure; when applied to 2-step RACH, in each of the above implementations, the first pilot is the PRACH pilot in message A of the random access procedure, and the first message is the physical uplink shared channel PUSCH in message A of the random access procedure.

[0336] Among them, when applied to 4-step RACH and 2-step RACH, the specific implementation method of indicating the terminal type of the terminal device in the first pilot and / or the first message according to the predefined method and / or indication information can be referred to the detailed description above and will not be described in detail here.

[0337] The access method described in the embodiment of the present application is described in detail below in conjunction with specific implementation methods.

[0338] Example 1

[0339] In this embodiment 1, taking 4-step RACH as an example, it is explained that according to a predefined method, it is determined whether to indicate the terminal type of the terminal device in the first pilot (i.e., Msg1), and according to a predefined method, it is determined whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3).

[0340] In this embodiment, the network device does not need to broadcast any information specifically used to instruct the terminal device to report the terminal indication. The terminal device can determine the stage for reporting the terminal type based on a predefined method, 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.

[0341] In this application, "reporting terminal type", "indicating terminal type" and "identifying terminal type" have similar meanings. In essence, the terminal device uses a specific transmission method / content to enable the network device to identify which type of terminal device the terminal device belongs to. Unless otherwise specified, no distinction is made.

[0342] In this first embodiment, a first implementation manner is adopted to determine whether to indicate the terminal type of the terminal device in the first pilot according to a first predefined manner. That is, when the network device configures a specific random access channel (PRACH) preamble sequence and / or a specific random access opportunity for the terminal device, the terminal type of the terminal device is indicated in the first pilot.

[0343] Typically, a network device (such as a gNB) broadcasts random access resource configuration information for normal UEs, indicating the RO resources and preamble sets used by normal UEs. RedCap UEs and normal UEs can share RO resources and preamble index sets. However, the gNB can also configure RedCap UE-specific RO resources and / or configure a specific preamble index set for RedCap UEs. For example, the gNB can broadcast 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.

[0344] When the gNB broadcasts RedCap UE-specific RACH resource configuration information, the RedCap UE shall initiate random access using the RedCap UE-specific RO and / or RedCap UE-specific preamble index. Accordingly, when the gNB receives the preamble sent by the UE in the RedCap UE-specific RO, or when the gNB detects that the preamble index belongs to the RedCap UE-specific preamble index, it can be determined that the UE initiating random access is a RedCap UE, thereby completing the identification of the RedCap UE.

[0345] 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 based on whether the gNB is configured with RedCap UE-specific RO resources and / or preamble index. If the gNB is configured with RedCap UE-specific RO resources and / or preamble index, the terminal type is indicated in Msg1; otherwise, the terminal type is not indicated in Msg1.

[0346] The specific implementation process of this embodiment is as follows Figure 5 As shown, including:

[0347] S510, determining whether the network device has configured a specific random access channel PRACH preamble sequence and / or a specific random access opportunity for the terminal device. If the determination result is yes, executing step S520; if the determination result is no, executing step S530;

[0348] S520, indicating the terminal type of the terminal device in Msg1;

[0349] S530: Do not indicate the terminal type of the terminal device in Msg1.

[0350] By adopting this implementation, whether to indicate the terminal type of the terminal device in Msg1 is determined in a predefined manner, which can reduce the gNB's overhead of indicating whether the UE indicates the terminal type during the Msg1 transmission phase.

[0351] In this first embodiment, the second implementation manner is adopted, and whether the terminal type of the terminal device is indicated in the first message (ie, Msg3) is determined according to the second predefined manner.

[0352] Specifically, according to the second predefined manner, indicating the terminal type of the terminal device in the first message includes at least one of the following:

[0353] In a case where the first pilot does not indicate the terminal type of the terminal device, indicating the terminal type of the terminal device in the first message;

[0354] In a case where the network device does not configure a specific random access channel PRACH preamble sequence and does not configure a specific random access opportunity for the terminal device, indicating the terminal type of the terminal device in the first message;

[0355] In a case where the network device configures a specific initial uplink bandwidth part BWP for the terminal device, indicating the terminal type of the terminal device in the first message;

[0356] In a case where the network device does not configure a specific random access channel PRACH preamble sequence and does not configure a specific random access opportunity for the terminal device, and configures a specific initial uplink bandwidth part BWP for the terminal device, indicating the terminal type of the terminal device in the first message;

[0357] Regardless of whether the first pilot indicates the terminal type of the terminal device, the terminal type of the terminal device is indicated in the first message. Specifically, unlike Msg1, the transmission resources of Msg3 are dynamically scheduled based on the information in Msg2. Among them, determining whether to indicate the terminal type of the terminal device in the Msg3 stage through the second predefined method includes the following methods:

[0358] Method 1: Determine whether to report in the Msg3 stage based on whether it was reported in the Msg1 stage;

[0359] To identify RedCap UEs, it is generally sufficient to perform identification in either Msg1 or Msg3. Therefore, a feasible approach is to determine that if a RedCap UE does not report its terminal type in Msg1, it will report it in Msg3; conversely, if it reports in Msg1, it will not report in Msg3.

[0360] 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 based on whether the gNB is configured with RedCap-specific RO resources and / or Preamble indexes - if the gNB is configured with RedCap-specific RO resources and / or Preamble indexes, it will not be reported in the Msg3 stage (and will be reported in the Msg1 stage); otherwise, it will be reported in the Msg3 stage (and not in the Msg1 stage).

[0361] The specific implementation process of this embodiment can be found in Figure 6 As shown, including:

[0362] S610, determining whether the network device has configured a specific random access channel PRACH preamble sequence and / or a specific random access opportunity for the terminal device. If the determination result is yes, executing step S620; if the determination result is no, executing step S630;

[0363] S620: Do not indicate the terminal type of the terminal device in Msg3;

[0364] S630: Indicate the terminal type of the terminal device in Msg3.

[0365] Method 2: Determine whether to indicate the terminal type of the terminal device in Msg3 based on whether the gNB is configured with the RedCap-specific initial uplink BWP;

[0366] Typically, the gNB broadcasts the configuration information for the initial downlink BWP and initial uplink BWP used by standard UEs. Standard UEs complete the random access procedure in the initial downlink BWP and initial uplink BWP, including receiving Msg2 and Msg4 in the initial downlink BWP and sending Msg3 in the initial uplink BWP. RedCap UEs and standard UEs can share the initial downlink BWP and initial uplink BWP. However, the gNB can also configure a RedCap UE-specific initial downlink BWP and / or initial uplink BWP. For example, the gNB can broadcast the configuration information for the RedCap UE-specific initial downlink BWP and / or initial uplink BWP, indicating the frequency range of the RedCap UE-specific initial downlink BWP and / or the frequency range of the initial uplink BWP, respectively.

[0367] When the gNB broadcasts a 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 a 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 shares the initial downlink BWP and initial uplink BWP with ordinary UEs, it means that the gNB considers it unnecessary to identify the RedCap UE during the initial access phase, and it is also unnecessary to identify the RedCap UE in the Msg3 phase. Otherwise, the terminal type can be reported in the Msg3 phase.

[0368] The specific implementation process of this embodiment can be found in Figure 7 As shown, including:

[0369] S710: Determine whether the gNB is configured with a RedCap UE-specific initial uplink BWP. If yes, proceed to step S720; if no, proceed to step S730.

[0370] S720, indicating the terminal type of the terminal device in Msg3;

[0371] S730: Do not indicate the terminal type of the terminal device in Msg3.

[0372] Method 3: Determine whether to indicate the terminal type in Msg3 based on whether it is reported in the Msg1 stage and whether the gNB is configured with the RedCap UE-specific initial uplink BWP;

[0373] This method three is a combination of the reporting methods of method one and method two; specifically, if the RedCap UE does not report in the Msg1 stage and the gNB is configured with a RedCap-specific initial uplink BWP, it is determined to be reported in the Msg3 stage; conversely, if it is reported in the Msg1 stage, or the gNB is not configured with a RedCap-specific initial uplink BWP, it is determined not to be reported in the Msg3 stage.

[0374] The specific implementation process of this embodiment can be found in Figure 8 As shown, including:

[0375] S810: Determine whether the gNB has configured a specific random access channel (PRACH) preamble sequence and / or a specific random access opportunity for the RedCap UE. If yes, proceed to step S820. If no, proceed to step S830.

[0376] S820, indicating the terminal type of the terminal device in Msg1, and not indicating the terminal type of the terminal device in Msg3;

[0377] S830: Determine whether the gNB has configured a specific initial uplink BWP for the RedCap UE. If yes, proceed to step S840. If no, proceed to step S850.

[0378] S840: Do not indicate the terminal type of the terminal device in Msg1, but indicate the terminal type of the terminal device in Msg3;

[0379] 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.

[0380] Mode 4: Regardless of whether the first pilot indicates the terminal type of the terminal device, the terminal type of the terminal device is always indicated in Msg3.

[0381] Since the terminal type is indicated by Msg3, it can be indicated by the specific state of the logical channel identifier (LCID) carried in the Msg3 message. For example, at least one state in the LCID indicates that the UE type is a RedCap UE. In the communication system, LCID is a high-level information, that is, information related to the Packet Data Convergence Protocol (PDCP) layer or the Media Access Control (MAC) layer. Sending Msg1, Msg3, etc. is a physical layer behavior. Cross-layer interaction (for example, 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 gNB, which is particularly detrimental to reducing the cost and complexity of RedCap UEs.

[0382] Therefore, in the embodiment of the present application, a feasible method is that the RedCap UE always indicates the terminal type of the terminal device in Msg3 (first message) regardless of whether it indicates the terminal type of the terminal device in Msg1 (first pilot).

[0383] In the 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 implementation process formed can be: Figure 9 As shown, including:

[0384] S910: Determine whether the gNB has configured a specific random access channel (PRACH) preamble sequence and / or a specific random access opportunity for the RedCap UE. If yes, proceed to step S920; if not, proceed to step S930.

[0385] S920, indicating the terminal type of the terminal device in Msg1, and indicating the terminal type of the terminal device in Msg3;

[0386] S930: Do not indicate the terminal type of the terminal device in Msg1, but indicate the terminal type of the terminal device in Msg3.

[0387] With this implementation, RedCap UE always indicates the terminal type of the terminal device in Msg3 regardless of whether it indicates the terminal type of the terminal device in Msg1. RedCap UE can reduce cross-layer interactions when determining at which stage to indicate the terminal type, thereby reducing complexity.

[0388] Furthermore, by adopting the method described in this embodiment, without introducing any "indication information", the RedCap UE can determine whether to indicate the UE type in the Msg1 sending stage and / or whether to indicate the UE type in the Msg3 sending stage, which not only realizes the identification of the UE type but also reduces the indication overhead.

[0389] Example 2

[0390] In this second embodiment, taking 4-step RACH as an example, it is explained that according to a predefined method, it is determined whether to indicate the terminal type of the terminal device in the first pilot (i.e., Msg1), and according to the indication method, it is determined whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3).

[0391] In this embodiment, from the perspective of the terminal device, whether to indicate the terminal type of the terminal device in Msg1 is determined in an implicit manner, and whether to indicate the terminal type of the terminal device in Msg3 is determined through indication information.

[0392] Among them, whether to indicate the terminal type of the terminal device in Msg1 is determined according to a predefined method. Please refer to the detailed description in the above embodiment 1 and will not be explained again here.

[0393] Furthermore, in this embodiment, whether the RedCap UE "indicates the UE type in Msg3" is determined based on the indication information of the gNB.

[0394] For example, the gNB may broadcast the indication information in a system message, such as including the indication information in System Information Block 1 (SIB1). After receiving the indication information, the RedCap UE determines whether to indicate the UE type in Msg3 based on the indication information; optionally, it may further determine how to indicate the UE type in Msg3.

[0395] Specifically, one possible method is to predefine an LCID used by RedCap UE to indicate the UE type, for example, the protocol specifies the LCID value used by RedCap UE in Msg3. In this way, the indication information only needs to indicate "whether the RedCap UE indicates the UE type in Msg3".

[0396] For example, the indication information includes only 1 bit of information, and the value of the information is 0 or 1, respectively indicating "need to indicate the UE type in Msg3" and "do not need to indicate the UE type in Msg3"; or it includes information that can take two states, and the two states of the information can take two states respectively indicating "need to indicate the UE type in Msg3" and "do not need to indicate the UE type in Msg3"; or, the indication information only indicates "need to indicate the UE type in Msg3", and if SIB1 does not include the indication information, it means "do not need to indicate the UE type in Msg3".

[0397] 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 may be multiple LCIDs predefined by the protocol, or the protocol does not predefine it. 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.

[0398] For example, if the protocol predefines N LCIDs (LCID_1, LCID_2, ... LCID_N) for indicating the reported UE type, the indication information indicates one of multiple states representing 'LCID_1', 'LCID_2', ..., 'LCID_N'. When 'LCID_X' is indicated, the RedCap UE indicates the UE type by reporting the Xth LCID in Msg3. When the indication information indicates 'not indicating UE type' or SIB1 does not include the indication information, it means "no need to indicate the UE type in Msg3".

[0399] For example, if the protocol does not predefine any LCID, the indication information may indicate the specific LCID value used by the RedCap UE when instructing the RedCap UE to indicate the UE type in Msg3. When the LCID value used by the RedCap UE is indicated, the RedCap UE indicates the UE type by reporting the indicated LCID in Msg3. If the indication information indicates 'not indicating the UE type' or SIB1 does not include the indication information, it means that "there is no need to indicate the UE type in Msg3."

[0400] In summary, through the method described in this embodiment, there is no need to introduce "indication information" for the indication of the terminal type in Msg1, while the "indication information" is used to indicate whether the terminal type in Msg3 needs to be reported, and optionally, the relevant indication information of the LCID reported by Msg3 is also included, thereby achieving a compromise between indication overhead and indication flexibility.

[0401] Example 3

[0402] In this third embodiment, taking 4-step RACH as an example, it is explained that according to the indication information, whether the terminal type of the terminal device is indicated in the first pilot (i.e., Msg1) is determined, and according to a predefined method, whether the terminal type of the terminal device is indicated in the first message (i.e., Msg3) is determined.

[0403] In this embodiment, whether the RedCap UE "indicates the UE type in Msg1" is determined based on the indication information of the gNB.

[0404] For example, the gNB may broadcast the indication information in a system message, such as including the indication information in System Information Block 1 (SIB1). After receiving the information, the RedCap UE determines whether to indicate the UE type in Msg1 based on the indication information; optionally, it may further determine how to indicate the UE type in Msg1.

[0405] Specifically, one possible method is that the indication information only needs to indicate "whether the RedCap UE indicates the UE type in Msg1". When the RedCap UE determines that the UE type needs to be indicated in Msg1 based on the indication, it uses the RedCap UE-specific RO resources and / or preamble index to initiate random access. The specific RedCap UE-specific RO resources and / or preamble indexes to be used can be predefined or determined based on the RedCap UE-specific RO resources and / or preamble indexes actually configured by the gNB.

[0406] For example, the indication information includes only 1 bit of information, and the value of the information is 0 or 1, respectively indicating "need to indicate the UE type in Msg1" and "do not need to indicate the UE type in Msg1"; or it includes information that can take two states, and the two states that can take the 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 SIB1 does not include the indication information, it means "do not need to indicate the UE type in Msg1".

[0407] Specifically, another possible method is that the indication information not only indicates "whether the RedCap UE indicates the UE type in the Msg1", but also needs to indicate the specific way in which the RedCap UE indicates the UE type in the Msg1.

[0408] For example, the indication information indicates whether the RedCap UE should initiate random access using RedCap UE-specific RO resources, using RedCap UE-specific preamble indexes, or using RedCap UE-specific RO resources and using RedCap UE-specific preamble indexes. If the indication information indicates 'not reporting' or SIB1 does not include the indication information, it means that "there is no need to indicate the UE type in Msg1."

[0409] In this embodiment, the method for determining whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3) according to a predefined method is the same as the method for determining whether to indicate the terminal type of the terminal device in Msg3 in Example 1, and will not be repeated here.

[0410] In summary, through the method in this embodiment, for the indication of UE type in Msg3, there is no need to introduce "indication information", and for the indication of UE type in Msg1, the "indication information" is used to indicate whether it needs to be reported, and optionally also includes the indication method of UE type indicated by Msg1 (specifically, initiating random access through RedCap UE-specific RO resources, initiating random access using RedCapUE-specific Preamble index, and one of the following: initiating random access through RedCap UE-specific RO resources and using RedCap UE-specific Preamble index), thereby achieving a compromise between indication overhead and indication flexibility.

[0411] Example 4

[0412] In this fourth embodiment, 4-step RACH is taken as an example to illustrate whether to indicate the terminal type of the terminal device in the first pilot (i.e., Msg1) according to the indication information, and whether to indicate the terminal type of the terminal device in the first message (i.e., Msg3) according to the indication information.

[0413] In this embodiment of the present application, whether the UE indicates the terminal type in Msg1 and whether the UE indicates the terminal type in Msg3 are both indicated by the indication information. Specifically, the method for the indication information to indicate that Msg3 reports the terminal type can refer to the detailed description in Example 2, and the method for the indication information to indicate that Msg1 reports the terminal type can refer to the detailed description in Example 3, which will not be repeated here.

[0414] For example, the indication information may indicate one of the following multiple 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 candidate information (4) if the terminal does not indicate the terminal type in either Msg1 or Msg3, the terminal device does not indicate the terminal type in either Msg1 or Msg3, or, when the network device does not send the indication information, the terminal does not indicate the terminal type in either Msg1 or Msg3.

[0415] In this embodiment, an indication message can be used to indicate whether the RedCap UE reports the terminal type in Msg1 and whether to report the terminal type in Msg3; further, the specific indication method of indicating the terminal type in Msg1 and / or the specific indication method of indicating the terminal type in Msg3 can also be indicated.

[0416] The method in this embodiment clearly instructs RedCap UEs whether to report their UE type during the initial access phase, the specific phase at which to report the UE type, and how to report the UE type. Therefore, the gNB can unambiguously instruct RedCap UEs to report their UE type at the appropriate phase as required, achieving maximum flexibility. For example, even if the gNB is configured with RedCap UE-specific RO and / or preamble for reporting the UE type in Msg1, when the cell's uplink load is heavy, the gNB can instruct the RedCap UE to report its UE type only in Msg3, thereby reducing uplink resource usage and achieving timely adjustments.

[0417] Example 5

[0418] In this fourth embodiment, taking 4-step RACH as an example, it is explained that based on the indication information, the terminal device determines whether to indicate the terminal type of the terminal device during the random access process, and determines, based on a predefined method, to indicate the terminal type of the terminal device in the first pilot (Mg1) or the first message (Mg3).

[0419] 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.

[0420] The indication information only generally indicates whether the UE needs to indicate the terminal type during the random access process, and does not need to specifically indicate whether the terminal should report in Msg1 or in Msg3.

[0421] For example, the indication information includes only one bit of information, and the value of the information is 0 or 1, respectively indicating "the terminal type needs to be indicated during the random access process" and "the terminal type does not need to be indicated during the random access process"; or it includes information that can take two states, and the two states that the information can take indicate "the terminal type needs to be indicated during the random access process" and "the terminal type does not need to be indicated during the random access process"; or, the indication information only indicates "the terminal type needs to be indicated during the random access process". If the SIB1 does not include the indication information, it means "the terminal type does not need to be indicated during the random access process".

[0422] On the other hand, when the indication information indicates that the terminal type needs to be reported in the random access process, it is determined in a predefined manner whether to indicate the terminal type in Msg1 or in Msg3.

[0423] The method for determining 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 the terminal type needs to be indicated in the random access process, whether to indicate the terminal type in Msg1 and whether to indicate the terminal type in Msg3 is determined according to whether the gNB is configured with RedCap UE-specific RO resources and / or Preamble indexes - if the gNB is configured with RedCap UE-specific RO resources and / or Preamble indexes, the terminal type is indicated in Msg1 and not in Msg3; otherwise, the terminal type is indicated in Msg3 and not in Msg1.

[0424] Specifically, the specific implementation process of this embodiment can be found in Figure 10 As shown, including:

[0425] S1010, judging whether it is necessary to indicate the terminal type of the RedCap UE during the random access process according to the indication information; if the judgment result is no, executing step S1020; if the judgment result is yes, executing step S1030;

[0426] 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;

[0427] S1030: Determine whether the gNB has configured a specific random access channel (PRACH) preamble sequence and / or a specific random access opportunity for the RedCap UE. If yes, proceed to step S1040; if not, proceed to step S1050.

[0428] S1040, indicating the terminal type of the terminal device in Msg1, and not indicating the terminal type of the terminal device in Msg3;

[0429] S1050: Do not indicate the terminal type of the terminal device in Msg1, but indicate the terminal type of the terminal device in Msg3.

[0430] The method described in this embodiment can clearly indicate whether a RedCap UE should report its UE type during the initial access phase and the specific phase at which it should report the UE type. Therefore, the gNB can accurately and precisely instruct the RedCap UE to report its UE type at the appropriate phase as required, achieving a compromise between flexibility and indication overhead.

[0431] It should be noted that in the embodiments of the present application, the access method described in Examples 1 to 5 takes the identification of ordinary UE and RedCap UE as an example to describe the method described in the embodiments of the present application in detail, but the access method described in the present application is not limited to the identification of terminal type RedCap UE, but can also be used for UE identification in other fields, such as identifying the service type of UE (different RAN slicing, etc.

[0432] In addition, in the embodiments of the present application, the access method described in Embodiment 1 to Embodiment 1 is described using 4-step RACH as an example, but the method described in this embodiment can also be applied to 2-step RACH, where when applied to 2-step RACH, the above-mentioned Msg1 can be replaced with the PRACH pilot in message A, and Msg3 can be replaced with the PUSCH in message A. The specific implementation method is the same as the above embodiment and is not described in detail here.
