[0028] In a first aspect, an embodiment of the present disclosure provides a resource processing method, the method being executed by a first type terminal, the method including:
[0029] The availability of the resource set is determined through a medium access control (MAC) layer based on a comparison result between a bandwidth in a group configuration parameter of at least one group in the resource set and a bandwidth supported by the first type of terminal.
[0030] In the above embodiment, the media access control MAC layer can determine whether the resource set is available based on the comparison result by comparing the bandwidth in the group configuration parameters of at least one group in the resource set with the bandwidth supported by the first type of terminal, thereby reliably using the resource set.

[0033] In the above embodiment, it is clarified that the resource set is the random access preamble group A and / or the random access preamble group B used for transmission of a 2-step random access channel RACH.
[0034] In combination with some embodiments of the first aspect, in some embodiments, the group configuration parameters include message A MsgA physical uplink shared channel PUSCH resource configuration parameters.
[0035] In the above embodiment, it is clarified that the group configuration parameters include message A MsgA physical uplink shared channel PUSCH resource configuration parameters.

[0038] In the above embodiment, by comparing the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group A and / or the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group B with the bandwidth supported by the first type of terminal, it can be clearly determined whether the resource set is available or unavailable based on the result obtained by the comparison, so that the resource set can be reliably used.
[0039] In combination with some embodiments of the first aspect, in some embodiments, determining the availability of the resource set based on a comparison result between the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group A and / or the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group B and the bandwidth supported by the first type of terminal includes:

[0041] In the above embodiment, when it is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group A and / or the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group B is greater than the bandwidth supported by the first type of terminal, it can be clearly determined that the resource set is unavailable, so that the resource set can be not used.
[0042] In conjunction with some embodiments of the first aspect, in some embodiments, determining, by the media access control (MAC) layer, the availability of the resource set based on a comparison result between the bandwidth in the group configuration parameters of at least one group in the resource set and the bandwidth supported by the first type of terminal includes:

[0044] In the above embodiment, when it is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group A is less than or equal to the bandwidth supported by the first type of terminal, the resource set can be determined to be available without considering the random access preamble code group B.
[0045] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:
[0046] During the random access process, it is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group B is greater than the bandwidth supported by the first type of terminal, and it is determined that the random access preamble code group B is unavailable or that the random access preamble code group B is not configured.
[0047] In the above embodiment, after determining that the resources are available, if it is determined during the random access process that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group B is greater than the bandwidth supported by the first type of terminal, it will be determined that the random access preamble code group B is unavailable or it is determined that the random access preamble code group B is not configured, so that the random access preamble code group B will not be selected for random access, thereby improving the random access efficiency.

[0083] FIG1a is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.
[0084] As shown in FIG. 1 a , a communication system 100 includes a terminal 101 and a network device 102 .
[0085] In some embodiments, terminal 101 may be a first type terminal.
[0086] In some embodiments, the network device 102 may include at least one of an access network device and a core network device.
[0087] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.
[0088] In some embodiments, the access network device may be, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.
[0089] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.
[0090] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.
[0091] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).
[0092] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.
[0093] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0094] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0095] In some embodiments, a new type of terminal, Reduced Capability UE (NR-lite), is proposed. Similar to IoT devices in LTE, these devices, based on 5G NR-lite, typically need to meet the following requirements: low cost and complexity, a certain degree of coverage enhancement, and power savings.
[0096] In some embodiments, after the introduction of Redcap terminals, unlike conventional enhanced mobile broadband (eMBB) terminals, Redcap terminals are used in some scenarios, such as industrial sensor scenarios and some wearable devices.
[0097] In some embodiments, since the time-frequency domain resources for scheduling are limited, Redcap terminals need to be indicated in advance, that is, the type of terminal can be identified during the random access process to facilitate reasonable scheduling.
[0098] In some embodiments, the terminal-based early identification is performed by partitioning the random access channel (RACH), that is, the random access resources are divided according to the feature combinations that need to be supported.
[0099] In some embodiments, a portion of the featureCombinationPreamblesList is allocated in the random access resources RACH-ConfigCommon used by 4-step RACH and the random access resources RACH-ConfigCommonTwoStepRA used by 2-step RACH for a specific feature combination. The portion of the random access resource that can be configured for the feature combination can be considered a common RACH resource.
[0100] In some embodiments, during the random access process of the terminal, resource selection is first performed in a portion of the featureCombinationPreamblesList to select a suitable random access resource. If the selection fails, a commom RACH resource is selected.
[0101] In some embodiments, after the introduction of R18 terminals, because their uplink data transmission bandwidth is limited to 5 MHz, the frequency domain range (nrofPRBs-PerMsgA-PO) of the msgA PUSCH configured in the MsgA-PUSCH-Config in the random access resource configuration used for 2-step RACH will exceed the uplink supported bandwidth of the R18 terminal. Therefore, when the terminal uses 2-step RACH, the message A (MsgA) physical uplink shared channel (PUSCH, Physical Uplink Shared CHannel) cannot be successfully decoded in the base station.
[0102] In some embodiments, for the random access resource configuration used by 2-step RACH, there are GroupA (random access preamble group A) and GroupB (random access preamble group B) configurations, that is, the resource configuration is divided into two groups, which are respectively configured with the preamble resources and the frequency domain range of msgA PUSCH.
[0103] In some embodiments, if a random access preamble group B of a 2-step random access type is configured, the following determination is required:
[0104] If the potential MsgA payload size is greater than ra-MsgA-SizeGroupA and the path loss is less than PCMAX-MSGA-PreambleReceivedTargetPower-MSGA-DeltaStreamble-MessagePowerOffsetGroupB (of the serving cell performing the random access procedure); or if the random access procedure is initiated for the Common Control Channel (CCCH) logical channel and the CCCH Service Data Unit (SDU) size plus the MAC subheader is greater than ra-MsgA-SizeGroupA, then the random access preamble group B is selected, otherwise, the random access preamble group A is selected.
[0105] In some embodiments, if the random access preamble group B of the 2-step random access type is not configured, the random access preamble group A is selected.
[0106] In some embodiments, Group B is optional and is selected only when agreed conditions are met (e.g., the payload size of the data to be transmitted is large and exceeds the size threshold of Group A, or the path loss is less than a threshold). In this case, Group B is selected; otherwise, Group A is selected.
[0107] In some embodiments, under the above group configuration, if the terminal selects a certain group but finds that the frequency domain range of the msgA PUSCH corresponding to the group has exceeded the terminal capability, the problem of whether to regard the entire resource set as available or unavailable needs to be solved.
[0108] FIG2a is an interactive diagram of a resource processing method according to an embodiment of the present disclosure. As shown in FIG2a, the embodiment of the present disclosure relates to a resource processing method for a communication system 100, the method comprising:

[0118] In some embodiments, the group configuration parameters are parameters of the random access preamble group A and / or the random access preamble group B used for transmission of a 2-step random access channel RACH.
[0119] In some embodiments, the group configuration parameters include message A MsgA physical uplink shared channel resource configuration parameters.
[0120] In some embodiments, the group configuration parameter may be a Msg A PUSCH resource configuration parameter.
[0121] In some embodiments, the Msg A PUSCH resource configuration parameters include bandwidth (nrofPRBs-PerMsgA-PO).
[0122] In some embodiments, the bandwidth included in the Msg A PUSCH resource configuration parameter may be a numerical value, for example, a maximum bandwidth value.
[0123] In some embodiments, the bandwidth included in the Msg A PUSCH resource configuration parameter may be a value range.
[0124] It should be noted that, in different usage scenarios, the bandwidth in this disclosure may correspond to a single value or a range of values, which is not limited here.
[0125] In some embodiments, the bandwidth supported by the first type of terminal may be a numerical value, that is, the first type of terminal supports a bandwidth less than or equal to the numerical value.
[0126] In some embodiments, the bandwidth supported by the first type of terminal may be a numerical range, that is, the first type of terminal supports a bandwidth within the numerical range.
[0127] Step S2102: The network device sends first information to the first type of terminal.
[0128] In some embodiments, the first type terminal receives first information sent by the network device.
[0129] In some embodiments, the first information is used to indicate: the radio resource control RRC layer and the media access control MAC layer of the first type of terminal determine the availability of the resource set based on the comparison result between the bandwidth in the group configuration parameters of at least one group in the resource set and the bandwidth supported by the first type of terminal.
[0130] It should be noted that, when step S2103 is that the first type terminal determines the availability of the resource set based on a predetermined communication protocol, step S2102 can be omitted.
[0131] Step S2103: The first type terminal determines the availability of the resource set.
[0132] In some embodiments, the first type terminal determines the availability of the resource set includes: determining that the resource set is available or determining that the resource set is unavailable. When it is determined that the resource set is unavailable, resources associated with the resource set will not be used.
[0133] In some embodiments, a (MAC, Media Access Control) layer of the first type of terminal determines the availability of the resource set.
[0134] In some examples, a media access control (MAC) layer of a first type of terminal determines the availability of the resource set based on a comparison result between a bandwidth in a group configuration parameter of at least one group in the resource set and a bandwidth supported by the first type of terminal.
[0135] In some embodiments, based on a predetermined communication protocol, the first type terminal determines the availability of the resource set.
[0136] In some embodiments, based on a predetermined communication protocol, the media access control MAC layer of the first type of terminal determines the availability of the resource set based on a comparison result between the bandwidth in the group configuration parameters of at least one group in the resource set and the bandwidth supported by the first type of terminal.
[0137] In some embodiments, the first type terminal determines the availability of the resource set based on the received information sent by the network device.
[0138] In some embodiments, based on the information received from the network device, the media access control MAC layer of the first type of terminal determines the availability of the resource set based on a comparison result between the bandwidth in the group configuration parameters of at least one group in the resource set and the bandwidth supported by the first type of terminal.
[0139] In some embodiments, a first type of terminal receives first information sent by a network device, and the first information is used to indicate that the media access control MAC layer of the first type of terminal determines the availability of the resource set based on a comparison result between the bandwidth in the group configuration parameters of at least one group in the resource set and the bandwidth supported by the first type of terminal.
[0140] In some embodiments, the MAC layer of the first type of terminal determines the availability of the resource set based on a comparison result between the bandwidth in the Msg A PUSCH resource configuration parameter contained in the group configuration parameter corresponding to the random access preamble code group A and / or the bandwidth in the Msg A PUSCH resource configuration parameter contained in the group configuration parameter corresponding to the random access preamble code group B and the bandwidth supported by the first type of terminal.
[0141] In some embodiments, the MAC layer of the first type of terminal determines that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group A and / or the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group B is greater than the bandwidth supported by the first type of terminal, and determines that the resource set is unavailable.
[0142] Exemplarily, the RRC layer of the first type terminal determines, based on a predetermined communication protocol, that the bandwidth in the MsgA PUSCH resource configuration parameter contained in any one (or at least one) group configuration parameter of GroupA and / or GroupB in a resource set for 2-step RACH transmission (a set of configured Random Access resources for 2-step RA type) is greater than the bandwidth supported by the terminal (or, the bandwidth range (nrofPRBs-PerMsgA-PO) in the MsgA PUSCH resource configuration parameter is outside the bandwidth range supported by the terminal), then the first type terminal determines that the RACH resource is unavailable (resource set, including the random access preamble group A and the random access preamble group B).
[0143] In some embodiments, the resource set includes only the random access preamble group A. It is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group A is greater than a bandwidth supported by the terminal, and the resource set is determined to be unavailable.
[0144] For example, if only Group A is configured in the resource set used for 2-step RACH transmission, and the bandwidth range (nrofPRBs-PerMsgA-PO) in its msgA PUSCH resource configuration is not within the bandwidth range supported by the first type of terminal, then the resource set used for 2-step RACH transmission is determined to be unavailable.
[0145] In some embodiments, the resource set includes only the random access preamble group A. Determining that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group A is greater than a bandwidth supported by the terminal determines that the random access preamble group A is unavailable.
[0146] In some embodiments, the resource set includes the random access preamble group A and the random access preamble group B. It is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group B is greater than a bandwidth supported by the terminal, and the resource set is determined to be unavailable.
[0147] Exemplarily, if GroupA and GroupB are configured in the resource set for 2-step RACH transmission, where the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration in the GroupB group configuration is not within the bandwidth range supported by the first type of terminal, then it is determined that the resource set for 2-step RACH transmission is unavailable.
[0148] In some embodiments, the resource set includes the random access preamble group A and the random access preamble group B. It is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group B is greater than the bandwidth supported by the terminal, and it is determined that the random access preamble group A and the random access preamble group B are unavailable.
[0149] In some embodiments, the resource set includes the random access preamble group A and the random access preamble group B. It is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group A is greater than a bandwidth supported by the terminal, and the resource set is determined to be unavailable.
[0150] Exemplarily, if GroupA and GroupB are configured in the resource set for 2-step RACH transmission, wherein in the GroupA group configuration, the bandwidth range (nrofPRBs-PerMsgA-PO) in its msgA PUSCH resource configuration is not within the bandwidth range supported by the first type of terminal, then it is determined that the resource set for 2-step RACH transmission is unavailable.
[0151] In some embodiments, the resource set includes the random access preamble group A and the random access preamble group B. It is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group A is greater than the bandwidth supported by the terminal, and it is determined that the random access preamble group A and the random access preamble group B are unavailable.
[0152] In some embodiments, the resource set includes the random access preamble group A and the random access preamble group B. It is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group A and the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group B are greater than a bandwidth supported by the terminal, and the resource set is determined to be unavailable.
[0153] For example, if GroupA and GroupB are configured in the resource set for 2-step RACH transmission, and the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration in the two group configurations is not within the bandwidth range supported by the first type of terminal, then it is determined that the resource set for 2-step RACH transmission is unavailable.
[0154] In some embodiments, the resource set includes the random access preamble group A and the random access preamble group B. It is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group A and the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group B are greater than a bandwidth supported by the terminal, and it is determined that the random access preamble group A and the random access preamble group B are unavailable.
[0155] In some embodiments, it is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group A is less than or equal to the bandwidth supported by the first type of terminal, and the random access resource set is determined to be available; otherwise, it is determined that the random access resource set is unavailable.
[0156] Exemplarily, for the first type of terminal, the network or protocol stipulates that if the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration of the GroupA group configuration of the resource set for 2-step RACH transmission (a set of configured Random Access resources for 2-step RA type) is not within the bandwidth range supported by the first type of terminal, then it is determined that the resource set for 2-step RACH transmission is unavailable; otherwise, it is determined that the resource set for 2-step RACH transmission is available.
[0157] For example, if only Group A is configured in the resource set used for 2-step RACH transmission, and the bandwidth range (nrofPRBs-PerMsgA-PO) in its msgA PUSCH resource configuration is not within the bandwidth range supported by the first type of terminal, then it is determined that the resource set used for 2-step RACH transmission is unavailable.
[0158] Exemplarily, if GroupA and GroupB are configured in the resource set for 2-step RACH transmission, and if the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration in the GroupA group configuration is not within the bandwidth range supported by the first type of terminal, then the resource set for 2-step RACH transmission is determined to be unavailable, otherwise it is available.
[0159] In some embodiments, determining that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble group A is less than or equal to the bandwidth supported by the first type of terminal determines that the resource set is available. During the random access process, the random access preamble group B is then determined.
[0160] For example, if Group A and Group B are configured in the resource set for 2-step RACH transmission (group A must be configured), as long as the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration in the GroupA group configuration is within the bandwidth range supported by the first type of terminal, the resource set for 2-step RACH transmission is still available.
[0161] In some embodiments, during the random access process, it is determined that the bandwidth in the Msg A PUSCH resource configuration parameter included in the group configuration parameter corresponding to the random access preamble code group B is greater than the bandwidth supported by the first type of terminal, and it is determined that the random access preamble code group B is unavailable or that the random access preamble code group B is not configured.
[0162] Exemplarily, during the random access process, the following determination process is added to the selection of the preamble:
[0163] If the bandwidth range (nrofPRBs-PerMsgA-PO) in the MSG A PUSCH resource configuration for Group B is not within the bandwidth supported by the first type of terminal, the Group B configuration is simply considered unavailable (considered as Random Access Preambles group B for 2-step RA type is not configured), that is, the selection of Group A is restored. The conditions for selecting Group B must also include the conditional judgment of terminal capability support. If the terminal capability does not support it, Group B cannot be selected and the only option is to fall back to Group A.
[0164] In some embodiments, before performing selection of a random access resource set divided for RACH and / or a random access resource set for common random access, the media access control MAC layer determines availability of the resource set based on a comparison result of a bandwidth in a group configuration parameter of at least one group in the resource set and a bandwidth supported by the first type of terminal;
[0165] In some embodiments, after selecting a random access resource set for RACH partitioning and / or a random access resource set for common random access, the media access control MAC layer determines the availability of the resource set based on a comparison result between the bandwidth in the group configuration parameters of at least one group in the resource set and the bandwidth supported by the first type of terminal.
[0166] Exemplarily, when the terminal determines the availability of the random access (RA, Random Access) resource set of the 2-Step RACH, the RA resource set divided by the RACH and the RA resource set including the common RACH can be selected in a relevant manner, and then the resource sets that do not meet the conditions can be further eliminated according to the terminal capabilities, thereby eliminating the available RA resource sets outside the terminal capability range.
[0167] It should be noted that it is also possible to first eliminate according to the terminal capability, and then select in a related manner the RA resource set for the RACH partition and the RA resource set including the common RACH.
[0168] In some embodiments, it is determined whether to select a 2-step random access method or to perform a 4-step random access. If the random access resource set is not available, the 2-step random access method cannot be selected.
[0169] Exemplarily, the terminal performs an operation of determining the availability of an RA resource set for a 2-Step RACH: when determining whether to use 4-step RACH and 2-Step RACH, the terminal may also consider the terminal capability for selecting 2-step RACH, that is, make a determination based on the availability in the above embodiment. Only when the availability is met can 2-step be performed, otherwise only 4-step random access can be performed.

[0211] In order to better understand the embodiments of the present disclosure, some exemplary embodiments are further described below:
[0212] In some embodiments, a specific type of terminal (first type of terminal) is protected in terms of resource selection during random access.
[0213] In some embodiments, the first type of terminal is a terminal with limited bandwidth capabilities.
[0214] In some embodiments, the transmission of uplink data (PUSCH) by the first type of terminal will not exceed a specific threshold bandwidth, such as 5M bandwidth.
[0215] In some embodiments, the first type of terminal is an enhanced eRedcap terminal of R18.
[0216] In some embodiments, Solution 1 determines (or decides, or judges) the availability of the entire resource set by configuring any (or at least) one group in Group A and / or Group B. Here, the resource set includes Group A (corresponding to the random access preamble group A in the present disclosure) and Group B (corresponding to the random access preamble group B in the present disclosure).
[0217] In some embodiments, for the first type of terminal, the network or protocol stipulates that if the bandwidth range (nrofPRBs-PerMsgA-PO) in any (or at least) group configuration of GroupA and / or GroupB in the resource set for 2-step RACH transmission (a set of configured Random Access resources for 2-step RA type) is outside the bandwidth range supported by the first type of terminal, then the resource set for 2-step RACH transmission is determined to be unavailable.
[0218] In some embodiments, if only Group A is configured in the resource set used for 2-step RACH transmission, and the bandwidth range (nrofPRBs-PerMsgA-PO) in its msgA PUSCH resource configuration is outside the bandwidth range supported by the first type of terminal, then the resource set used for 2-step RACH transmission is considered unavailable.
[0219] In some embodiments, if GroupA and GroupB are configured in the resource set for 2-step RACH transmission, where the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration of GroupB is outside the bandwidth range supported by the first type of terminal, then the resource set for 2-step RACH transmission is considered unavailable.
[0220] In some embodiments, if GroupA and GroupB are configured in the resource set for 2-step RACH transmission, where the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration in the GroupA group configuration is outside the bandwidth range supported by the first type of terminal, then the resource set for 2-step RACH transmission is considered unavailable.
[0221] In some embodiments, if GroupA and GroupB are configured in the resource set for 2-step RACH transmission, and the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration in the two group configurations is outside the bandwidth range supported by the first type of terminal, then it is determined that the resource set for 2-step RACH transmission is unavailable.
[0222] In some embodiments, Solution 2 determines (or decides, or judges) the availability of the entire resource set through the configuration of Group A.
[0223] In some embodiments, for the first type of terminal, the network or protocol stipulates that if the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration of the GroupA group configuration of the resource set for 2-step RACH transmission (a set of configured Random Access resources for 2-step RA type) is outside the bandwidth range supported by the first type of terminal, then it is determined that the resource set for 2-step RACH transmission is unavailable; otherwise, it is determined that the resource set for 2-step RACH transmission is available.
[0224] In some embodiments, if only Group A is configured in the resource set used for 2-step RACH transmission, and the bandwidth range (nrofPRBs-PerMsgA-PO) in its msgA PUSCH resource configuration is outside the bandwidth range supported by the first type of terminal, then it is determined that the resource set used for 2-step RACH transmission is unavailable.
[0225] In some embodiments, if GroupA and GroupB are configured in the resource set for 2-step RACH transmission, and if the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration in the GroupA group configuration is outside the bandwidth range supported by the first type of terminal, then the resource set for 2-step RACH transmission is determined to be unavailable, otherwise it is available.
[0226] In some embodiments, if Group A and Group B are configured in the resource set for 2-step RACH transmission (group A must be configured), as long as the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration in the GroupA group configuration is within the bandwidth range supported by the first type of terminal, the resource set for 2-step RACH transmission is still available.
[0227] In some embodiments, during the random access process, the following decision is added to the selection of the preamble:
[0228] If the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration of GroupB is outside the bandwidth range supported by the first type of terminal, however, it is only considered that the GroupB group configuration is unavailable (regarded as Random Access Preambles group B for 2-step RA type is not configured), and then it falls back to selecting groupA.
[0229] Solution 2 is more flexible than Solution 1. Even if group B is unavailable, you can still fall back to group A, ensuring that the entire resource set is available. This means that the conditions for selecting Group B must be supplemented with the terminal's capability support. If the terminal does not support Group B, Group B cannot be selected, or the Group B configuration is deemed unavailable (considered as "Random Access Preambles group B for 2-step RA type is not configured"), forcing you to fall back to group A.
[0230] The above two solutions can be implemented when the terminal makes the following judgments:
[0231] In some embodiments, the first type of terminal may determine the availability of the RA resource set of the 2-Step RACH after selecting the RA resource set of the RACH partition and the RA resource set including the common RACH in accordance with the existing method, and then further eliminate the unqualified resource sets or unavailable resource sets according to the terminal capabilities (i.e., determine the availability of the resource set according to the above scheme 1 or scheme 2), and eliminate the available RA resource sets outside the terminal capability range.
[0232] In some embodiments, available RA resource sets outside the capability range may be eliminated first according to the terminal capability, and then the RA resource set for the RACH partition and the RA resource set including the common RACH may be selected according to the existing method.
[0233] In some embodiments, when determining whether to use 4-step RACH or 2-step RACH, the first type of terminal may determine whether to use 2-step RACH by considering the existing decision process (such as signal transmission quality, for example, Reference Signal Received Power (RSRP)). 2-step RACH can only be used when a threshold is met. Furthermore, the terminal capability, that is, the availability in the above embodiment, may be considered when selecting 2-step RACH. Only when the resource set is available can 2-step RACH be performed; otherwise, only 4-step random access can be performed. That is, a resource availability condition is added to the relevant decision conditions.
[0234] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.
[0235] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions.
