When base station 120 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack.

In an NTN network, access device 120 can be a base station mounted on aerial equipment such as a satellite, or it can be a ground-based base station communicating with aerial equipment such as satellites via a ground station (e.g., in a transparent payload network architecture).

[0070] Base station 120 and user equipment 110 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0075] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0076] To better understand the embodiments of this disclosure, the following describes relevant paging scenarios:

[0077] In one embodiment, Redcap terminals in R17 require early notification due to limited time-frequency domain resources for scheduling. The terminal type can be identified during the random access process, facilitating appropriate scheduling.

[0078] In one embodiment, early terminal identification is performed through Random Access Channel (RACH) partitioning. Random access resources can be partitioned according to the combinations of features that need to be supported. A portion of the random access resources RACH-ConfigCommon used in 4-step RACH and RACH-ConfigCommonTwoStepRA used in 2-step RACH is allocated to featureCombinationsPreamblesList for specific feature combinations. The portion of random access resources that can be configured for feature combinations can be considered as public RACH resources.

[0079] In one embodiment, during the random access process of the terminal, a suitable random access resource will be selected from a subset of featureCombinationPreamblesList; if the selection fails, the common RACH resource will be selected.

[0080] In one embodiment, after the introduction of the R18 terminal, because its uplink data transmission bandwidth is limited to 5MHz, the frequency domain range (nrofPRBs-PerMsgA-PO) of msgAPUSCH configured in MsgA-PUSCH-Config for the random access resource configuration used in 2-step RACH will exceed the uplink supported bandwidth of the R18 terminal. This will cause the msgA PUSCH to fail to be decoded successfully at the base station when the terminal uses 2-step RACH. Therefore, it is necessary to consider excluding this part of the resources during random access resource selection.

[0081] With the introduction of eRedcap terminals in Release 18, compared to Redcap terminals in Release 17, the scheduling of time-frequency domain resources becomes more limited. The solution provided in this disclosure at least facilitates the terminal in making reasonable resource selections during random processes.

[0141] In one embodiment, first information is sent to a first type of terminal via broadcast signaling.

[0142] In one embodiment, first information is sent to a first type of terminal; wherein the first information is used to indicate whether the first type of terminal can or cannot use the predetermined resource configuration information to perform two-step random access data transmission; the predetermined resource configuration information is predetermined resource configuration information with bandwidth exceeding the bandwidth supported by the first type of terminal; the bandwidth supported by the first type of terminal is less than a bandwidth threshold; the predetermined resource configuration information is Physical Uplink Shared Channel (PUSCH) resource configuration information for a random access message (msgA). Exemplarily, the predetermined resource configuration information is the network-configured MsgA-PUSCH-Config and / or the network-configured separateMsgA-PUSCH-Config.

[0143] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0144] To better understand the embodiments of this disclosure, the following four exemplary embodiments further illustrate the technical solutions of this disclosure:

[0145] Example 1:

[0146] This disclosure includes a method for resource selection during random access for a specific type of terminal (corresponding to the first type of terminal in this disclosure).

[0147] In one embodiment, the first type of terminal is an enhanced eRedcap terminal of R18, which is different from the second type of R17 Redcap terminal and the third type of terminal (ordinary terminal, or eMBB terminal).

[0148] In one embodiment, the first type of terminal will not exceed a threshold bandwidth, such as 5M bandwidth, for uplink data (PUSCH data) transmission.

[0149] In one embodiment, for the first type of terminal, whether the network (corresponding to the method of base station sending first information in this disclosure) or the protocol agreement (corresponding to the method of determining first information based on predetermined protocol rules in this disclosure) can use msgA PUSCH resource configuration (corresponding to predetermined resource configuration information in this disclosure) that exceeds the terminal's capability range to perform 2-step RACH transmission.

[0150] In one embodiment, if the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource configuration is greater than the bandwidth supported by the terminal, then it exceeds the terminal's capability range.

[0151] In one embodiment, the protocol stipulates that Type 1 terminals cannot use msgA PUSCH resource configurations exceeding their supported bandwidth for 2-step RACH transmission.

[0152] In one embodiment, the protocol stipulates that the first type of terminal can use msgA PUSCH resource configuration exceeding its supported bandwidth for 2-step RACH transmission.

[0153] In one embodiment, the network instructs the first type of terminal that it may or may not use a msgA PUSCH resource configuration exceeding its supported bandwidth for 2-step RACH transmission. It should be noted that if the network supports 2-step RACH transmission with a msgA PUSCH resource configuration exceeding its supported bandwidth capacity, there is a risk of msgA PUSCH decoding failure. However, if the base station can accept this, it can proceed in this manner.

[0154] In one embodiment, the network notifies the first type of terminal via dedicated signaling or broadcast information whether it can use msgA PUSCH resource configuration exceeding its supported bandwidth for 2-step RACH transmission.

[0155] In one embodiment, the msgA PUSCH resource configuration is the network-configured MsgA-PUSCH-Config and / or the network-configured separateMsgA-PUSCH-Config, which includes both the MsgA-PUSCH resource configuration of the common RACH and the resource configuration of the RACH partition.

[0156] In one embodiment, if the protocol stipulates that a first-type terminal cannot use msgAPUSCH resource configuration exceeding its supported bandwidth for 2-step RACH transmission, then when determining the availability of the Random Access (RA) resource set, the RA resource set exceeding the terminal's capability needs to be set as unavailable.

[0157] In one embodiment, when the terminal determines the availability of RA resource sets for 4-step RACH and 2-step RACH, after selecting the RA resource sets according to a predetermined method (see the embodiments described above for paging-related scenarios) or after selecting the RA resource sets for the RACH partition and the RA resource sets including the common RACH according to a predetermined method, the terminal further eliminates available RA resource sets outside its capabilities.

[0158] In one embodiment, the terminal can first be eliminated based on its capabilities, and then the RA resource set divided for RACH and the RA resource set including common RACH can be selected in the existing manner.

[0159] Example 2:

[0160] This example illustrates how to determine the availability of a set of random access resources:

[0161] For each set of random access resources (or resource sets, hereinafter the same) configured for the 4-step RA type and for each set of random access resources (resource sets) configured for the 2-step RA type, the MAC entity should:

[0162] If a RedCap directive is configured for a set of random access resources (resource set):

[0163] This set of random access resources (resource set) is considered unavailable for random access procedures that are not applicable to RedCap directives.

[0164] If an SDT indicator is configured for a set of random access resources (resource set):

[0165] This set of random access resources is considered unavailable for random access procedures not triggered by Small Data Transmission (SDT).

[0166] If an NSAG indicator is configured for a set of random access resources (resource set):

[0167] The set of random access resources is considered unavailable for the random access procedure unless the set of random access resources is triggered in response to the corresponding NSAG indication.

[0168] If MSG3 repeat indication is configured for a set of random access resources (resource set):

[0169] If MSG3 is repeatedly not applicable, then that set of random access resources (resource set) is considered unavailable for the random access procedure.

[0170] If a set of random access resources (resource set) is not configured with any RedCap, SDT, NSAG, or MSG3 repeat indication:

[0171] Random access resources (resource sets) are considered to be unassociated with any characteristic indications.

[0172] After the above steps, for specific types of terminals (such as eRedcap users of R18), the following judgment is still required:

[0173] For R18 eRedcap, if the PUSCH allocation for a set of random access resources (resource set) exceeds the bandwidth supported by R18 eRedcap, then the set of random access resources (resource set) is considered unusable for the random access process.

[0174] Example 3:

[0175] In Example 2, if the random access resource selection process follows the existing procedure to determine the availability of the random access resource set, it can be further improved by first eliminating random access resources that are within the range supported by the terminal's capabilities.

[0176] For R18 eRedcap, if the PUSCH allocation for a set of random access resources (resource set) exceeds the bandwidth supported by R18 eRedcap, then the set of random access resources (resource set) is considered unusable for the random access process.

[0177] Whether R18 eRedcap applies to this example for a given terminal depends on the higher-layer instructions during random access.

[0178] Example 4:

[0179] In one embodiment, when deciding whether to use 4-step RACH or 2-step RACH, the terminal's capabilities must also be considered when choosing 2-step RACH.

[0180] In one embodiment, if the BWP used for the random access procedure is configured with 2-step and 4-step RA type random access resources (e.g., as specified in Clause 5.1.1b of TS 38.321) within the selected set of random access resources, and the downlink path loss reference RSRP is higher than msgA-RSRP-Threshold and the UE is capable of supporting the selected 2-step random access resource set (e.g., the msgAPUSCH bandwidth in this resource set is within the terminal's capability support range), or if the BWP used for the random access procedure is configured with only a 2-step RA type random access resource set within the selected set of random access resources, and the UE is capable of supporting the selected 2-step random access resource set (e.g., the msgAPUSCH bandwidth in this resource set is within the terminal's capability support range), then RA_TYPE is set to 2-step RA. Otherwise, RA_TYPE is set to 4-step RA.
