[0096] 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.

[0097] 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.

[0098] 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).

[0099] 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.

[0100] 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.

[0101] 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).

[0102] In some embodiments, Redcap terminals, similar to IoT devices in LTE, typically need to meet the following requirements: 1. Low cost and complexity; 2. A certain degree of coverage enhancement; and 3. Power conservation. After the introduction of Redcap users, unlike conventional enhanced mobile broadband (eMBB) users, Redcap users are used in certain scenarios, such as industrial sensor scenarios and some wearable devices.

[0103] In some embodiments, Redcap users may have limited time-frequency domain resources for scheduling, and therefore need to provide early indication, that is, send information that can identify the type of terminal during the random access process to facilitate reasonable scheduling.

[0104] In some embodiments, terminal-based early identification is performed through Random Access Channel (RACH) partitioning. Specifically, the random access resources are divided according to the feature combinations to be supported. Therefore, a portion of the FeatureCombinationPreamblesList within the random access resources is allocated for use by specific feature combinations (such as RedCap). The portion of the random access resources allocated for use by the feature combination can be considered common random access (RACH) resources.

[0105] In some embodiments, for Redcap users, configuration includes 2-step random access (2step-RACH) resources and 4-step random access (4step-RACH) resources for early indication.

[0106] In some embodiments, after the introduction of the eRedcap terminal, the corresponding uplink and downlink data transmission bandwidth is limited to 5Mhz.

[0107] In some embodiments, separate resources for early indication are configured for eRedcap users on 4-step RACH, adding a new, specific feature set to eRedcap. Thus, if the network configures separate resources for early indication for eRedcap users with 4-step, they will be preferred. If the network does not configure separate resources for early indication for eRedcap users, R18 eRedcap users can share 4-step RACH resources with R17 Redcap users.

[0108] In some embodiments, during the random access process of the terminal, RACH resources are first selected, that is, available RACH resources are selected based on characteristics currently applicable to the random access process initiated by the terminal.

[0109] In some embodiments, the characteristics are typically determined by an upper layer or a media access control (MAC) layer itself, and are used as a basis for subsequent RACH resource selection according to the characteristics priority level.

[0110] In some embodiments, typically for a Redcap or eRedcap user: when initiating a random access procedure, the applicability of (e)Redcap is also determined by upper layers. For eRedcap, even if the network can select random access resources configured for the Redcap feature, the subsequent RACH resource selection based on feature priority will still be based on the features determined by the Upper layer or MAC layer itself (e.g., eRedcap), and will be used as the basis for subsequent RACH resource selection based on feature priority, which may cause a mismatch.

[0111] FIG2a is an interactive diagram illustrating a resource determination method according to an embodiment of the present disclosure. As shown in FIG2a , the embodiment of the present disclosure relates to a resource determination method for a communication system 100, the method comprising:

[0198] In some embodiments, the bandwidth supported by the first type of terminal is less than a bandwidth threshold.

[0199] In some embodiments, the bandwidth supported by the first type of terminals is smaller than the bandwidth supported by the second type of terminals.

[0200] In some embodiments, the first terminal is an enhanced reduced capability eRedcap terminal and the second terminal is a Redcap terminal.

[0201] In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through two exemplary embodiments:

[0202] Example 1:

[0203] In some embodiments, the present disclosure provides a method for a specific type of terminal (corresponding to a first type of terminal) to select resources in a random access process.

[0204] In some embodiments, the first type of terminal is an enhanced eRedcap terminal of Release 18 (R18) (different from R17 Redcap (corresponding to the second type of terminal) and the third type of terminal (eg, a normal terminal or an eMBB terminal)).

[0205] In some embodiments, the first type of terminal has a smaller baseband processing bandwidth than the second type of terminal and the third type of terminal.

[0206] In some embodiments, for the first type of terminal, when selecting a RACH resource set according to a feature priority level (corresponding to a first behavior), a feature suitable for triggering the random access procedure is determined according to a first determination method (corresponding to a first approach).

[0207] In some embodiments, the first determination method determines that the characteristic applicable to triggering the random access procedure is determined according to a higher layer or a MAC layer.

[0208] In some embodiments, when performing the first behavior, the terminal determines the priority level of the characteristic determined in the first behavior according to the characteristic acquired in the first determination manner, and utilizes the determined characteristic priority level.

[0209] In some embodiments, for eRedcap users, when selecting a RACH resource set based on feature priority, eRedcap will be considered as a feature applicable to the currently triggered RACH, and when selecting a RACH resource set based on feature priority, the feature priority of eRedcap will be utilized.

[0210] In some embodiments, for the first type of terminal, when selecting a RACH resource set according to the feature priority level (first behavior), the feature suitable for triggering the random access process is determined according to the second determination method (second method).

[0211] In some embodiments, the second determination method determines the characteristic applicable to triggering the random access procedure according to a characteristic associated with the selected random access resource.

[0212] In some embodiments, the characteristic associated with the random access resource may be a characteristic originally (or initially) configured for the random access resource (e.g., characteristic "Redcap"). Based on the second determination method, the characteristic (e.g., characteristic "Redcap") may be determined as a characteristic applicable to triggering the random access procedure. Thus, even if the terminal is an eRedcap terminal, because a random access resource originally configured with the characteristic "Redcap" is selected, "Redcap" may be determined as a characteristic applicable to the random access procedure triggered by the eRedcap user.

[0213] In some embodiments, the characteristic associated with the random access resource may be the characteristic "Redcap" associated with a certain type of terminal (e.g., a Redcap terminal) originally configured for the random access resource. The characteristic "Redcap" associated with the Redcap type terminal may then be determined as a characteristic suitable for triggering the random access procedure based on the second determination method. Thus, even if an eRedcap terminal selects a random access resource originally configured with the characteristic "Redcap" associated with a certain type of terminal (e.g., a Redcap terminal), "Redcap" is considered to be a characteristic suitable for triggering the random access procedure for this eRedcap user.

[0214] In some embodiments, when performing the first behavior, the terminal determines the priority level of the characteristic determined in the first behavior according to the characteristic acquired in the second determination manner.

[0215] In some embodiments, for eRedcap users, if R17Redcap 4-step or R17Redcap 2-step resources are selected, when selecting the RACH resource set based on the feature priority level, Redcap will be considered as the feature applicable to the currently triggered RACH, and when selecting the RACH resource set based on the feature priority level, the feature priority of Redcap will be used.

[0216] In some embodiments, for eRedcap users, if R18eRedcap 4-step or R17Redcap 2-step resources are selected, when selecting the RACH resource set based on the feature priority level, both eRedcap and Redcap will be considered as applicable features of the currently triggered RACH, and when selecting the RACH resource set based on the feature priority level, the feature priority of eRedcap and Redcap will be used.

[0217] In some embodiments, for the first type of terminal, when selecting a RACH resource set according to the feature priority level (first behavior), the feature suitable for triggering the random access process is determined according to the first determination method and the second determination method.

[0218] In some embodiments, for eRedcap users, if R18eRedcap 4-step or R17Redcap 2-step resources are selected, when selecting the RACH resource set according to the feature priority level, both eRedcap and Redcap will be considered as applicable features of the currently triggered RACH (determined according to the first determination method and the second determination method, respectively), and when selecting the RACH resource set according to the feature priority level, the feature priority of eRedcap and Redcap will be used.

[0219] Example 2:

[0220] The selection of random access resource sets based on feature priority involves the following:

[0221] The MAC entity shall:

[0222] In some embodiments, among the set of available random access resources for the random access procedure, resources configured with characteristics that can satisfy the highest priority characteristic assigned in the feature priority among all characteristics of the random access procedure are identified.

[0223] In one embodiment, if a single set of random access resources is identified, that set of random access resources is selected. Otherwise, if more than one set of random access resources is identified, the process is repeated, using as input the identified set of random access resources and the features applicable to the current random access procedure and assigned the highest priority in the feature priority, excluding features already considered. Otherwise (i.e., no set of random access resources is identified), the process is repeated, using as input the previously identified available set of random access resources and the features applicable to the current random access procedure and assigned the highest priority in the feature priority, excluding features already considered.

[0224] In some embodiments, for an eRedcap UE, if one or more groups of random access resources are configured with an indication for Redcap or configured for Redcap, and the eRedcap is available, the eRedcap UE will consider the "Redcap" feature to be applicable to the random access procedure. That is, when selecting resources based on feature priority, the "Redcap" priority configuration will be used as the feature priority for decision making.

[0225] In some embodiments, for eRedcap users, if R17Redcap 4-step and / or R17Redcap 2-step resources are selected, Redcap will be considered as the applicable feature for the currently triggered RACH when selecting a RACH resource set based on feature priority. The feature priority of Redcap will also be used when selecting a RACH resource set based on feature priority. (For example, R17 resources are selected for both 2-step and 4-step.)

[0226] In some embodiments, a higher layer determines applicable features for a random access procedure initiated by a terminal. Exemplarily, the higher layer may include a Radio Resource Control (RRC) layer or a Non Access Stratum (NAS) layer.

[0227] For example, for a Redcap terminal, a higher layer of the Redcap terminal determines that the characteristic "Redcap" is applicable to a random access process initiated by the terminal for a certain random access resource.

[0228] In one embodiment, the MAC layer determines applicable features for a terminal-initiated random access procedure.

[0229] For example, the applicable features of the random access procedure initiated by the terminal are agreed upon through a protocol. For example, when the terminal meets the Small Data Transmission (SDT) condition, the applicable feature when initiating the random access procedure is SDT. Therefore, a Redcap terminal can also meet the SDT initiation condition. In this case, for the Redcap terminal, both the "Redcap" and "SDT" features are applicable to the random access procedure initiated by the terminal.

[0230] 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.

In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated.
