[0036] To facilitate understanding for those skilled in the art, the embodiments of this disclosure illustrate the technical concept of the embodiments of this disclosure by providing several examples. Of course, those skilled in the art will know that the several embodiments provided by the embodiments of this disclosure may be performed individually, in combination with the methods of other embodiments in the embodiments of this disclosure, or individually or in combination with some methods of other related technologies, and are not limited to the embodiments of this disclosure.

[0037] To better understand the embodiments of this disclosure, the following describes a paging scenario.

[0038] In one embodiment, the R17 Redcap terminal requires early instruction due to limitations on scheduled time-frequency domain resources. Recognizing the terminal type during the random access procedure facilitates reasonable scheduling.

[0039] In one embodiment, early recognition by the terminal is performed by partitioning the Random Access Channel (RACH). Random access resources can be partitioned according to the combination of features that need to be supported (Featurecombination). In the random access resource RACH-ConfigCommon used in 4-step random access (4-step RACH) and the random access resource RACH-ConfigCommonTwoStepRA used in 2-step random access (2-step RACH), a portion of the featureCombinationPreamblesList is partitioned for use in specific feature combinations. The random access resource can be configured with a portion used for feature combinations, and the rest is considered a common RACH resource.

[0040] In one embodiment, during the random access procedure of a terminal, resource selection is prioritized using certain featureCombinationPreamblesLists to select an appropriate random access resource. If selection fails, a common RACH resource is selected.

[0041] In one embodiment, after the R18 terminal is introduced, its uplink data transmission bandwidth is limited to 5MHz. As a result, the frequency domain range (nrofPRBs-PerMsgA-PO) of the msgA PUSCH set in MsgA-PUSCH-Config in the random access resource configuration used in 2-step RACH may exceed the bandwidth supported by the R18 terminal's uplink. This prevents the msgA PUSCH from being successfully decoded at the base station when the terminal is using 2-step RACH. Therefore, it is necessary to consider excluding certain resources when selecting random access resources.

[0042] Following the introduction of R18 eRedcap terminals, they are more limited by scheduled time-frequency domain resources compared to R17 Redcap terminals. The proposed techniques provided by this disclosure facilitate at least the rational selection of resources in a random process by the terminal.

[0043] As shown in Figure 2, embodiments of the present disclosure provide a method for determining a random access resource, the method being performed by a first type of terminal, and the method comprising the following steps:

[0045] Here, the terminals relating to this disclosure may be, but are not limited to, mobile phones, wearable devices, in-vehicle terminals, roadside units (RSUs), smart home terminals, industrial sensing devices, and / or medical devices. In some embodiments, the terminal may be a Redcap terminal or a newer version of a given wireless NR terminal (e.g., an R17 NR terminal). In one embodiment, the first type of terminal may be an R18 enhanced Redcap terminal, which is distinct from the second type of terminal (an R17 Redcap terminal) and the third type of terminal (a regular terminal or an Enhanced Mobile Broadband (eMBB) terminal). Exemplarily, the transmission bandwidth of the first type of terminal may be 5 MHz or less.

[0063] Setting the value to the second value may simply mean setting the default value to the second value.

[0064] In one embodiment, based on first information, it is determined whether or not to perform two-step random access data transmission using predetermined resource configuration information, where the bandwidth indicated by the predetermined resource configuration information exceeds the bandwidth supported by the first type terminal, and the first information is for indicating whether or not the first type terminal can perform two-step random access data transmission using the predetermined resource configuration information, and the bandwidth supported by the first type terminal is smaller than the bandwidth threshold.

In embodiments of this disclosure, the dedicated signaling may be radio resource control (RRC) signaling or media access control (MAC) control element (CE) signaling, etc.

[0098] In one embodiment, first information is transmitted to a first type terminal via broadcast signaling.

[0099] In one embodiment, first information is transmitted to a first type terminal, where the first information indicates whether or not the first type terminal can perform two-step random access data transmission using predetermined resource configuration information, the predetermined resource configuration information being predetermined resource configuration information whose bandwidth exceeds the bandwidth supported by the first type terminal, the bandwidth supported by the first type terminal is less than the bandwidth threshold, and the predetermined resource configuration information is A random access message (msgA) physical uplink shared channel (PUSCH) resource configuration information. Exemplarily, the predetermined resource configuration information is MsgA-PUSCH-Config configured by the network and / or separateMsgA-PUSCH-Config configured by the network.

[0100] Those skilled in the art will understand that the methods provided in the embodiments of this disclosure may be performed alone or in conjunction with some of the methods in the embodiments of this disclosure or some of the methods of related technology.

[0101] To better understand the embodiments of this disclosure, the technical invention of this disclosure will be further explained by four exemplary embodiments below.

[0102] Example 1: This disclosure includes a method by which a specific type of terminal (corresponding to the first type of terminal in this disclosure) performs resource selection in a random access procedure.

[0103] In one embodiment, the first type terminal is an extended eRedcap terminal of the R18, and the first type terminal is different from the second type terminal (R17 Redcap terminal) and the third type terminal (a normal terminal or eMBB terminal).

[0104] In one embodiment, the first type of terminal does not exceed a threshold bandwidth, for example, 5M bandwidth, for transmitting uplink data (PUSCH data).

[0105] In one embodiment, it is defined whether a 2-step RACH can be transmitted to the first type of terminal using msgA PUSCH resource settings (corresponding to predetermined resource setting information in this disclosure) that exceed the capabilities of the terminal, via a network (corresponding to the form in which a base station transmits the first information in this disclosure) or a protocol (corresponding to the form in which the first information is determined based on predetermined protocol rules in this disclosure).

[0106] In one embodiment, if the bandwidth range (nrofPRBs-PerMsgA-PO) in the msgA PUSCH resource setting is greater than the bandwidth supported by the terminal, it exceeds the terminal's capabilities.

[0107] In one embodiment, the protocol stipulates that a first type terminal cannot perform a 2-step RACH transmission using msgA PUSCH resource settings that exceed the bandwidth it supports.

[0108] In one embodiment, the protocol specifies that a first type of terminal can perform a 2-step RACH transmission using msgA PUSCH resource settings that exceed the bandwidth supported by it.

[0109] In one embodiment, the network indicates whether or not a first-type terminal can transmit a 2-step RACH using an msgA PUSCH resource configuration that exceeds its supported bandwidth. Note that if the network supports transmitting a 2-step RACH with an msgA PUSCH resource configuration that exceeds its supported bandwidth capacity, there is a risk of msgA PUSCH decoding failure. However, this can be done if the base station accepts it.

[0110] In one embodiment, the network notifies, via dedicated signaling or broadcast information, whether a first type terminal can transmit a 2-step RACH using an msgA PUSCH resource setting that exceeds the bandwidth it supports.

[0111] In one embodiment, the msgA-PUSCH resource configuration is MsgA-PUSCH-Config configured by the network and / or separateMsgA-PUSCH-Config configured by the network, i.e., it includes both the MsgA-PUSCH resource configuration for the common Rach and the resource configuration for the Rach partition.

[0112] In one embodiment, if the protocol specifies that a first type terminal cannot perform a 2-step RACH transmission using msgA PUSCH resource settings that exceed the bandwidth it supports, then when determining the availability of random access (RA) resource sets, RA resource sets that exceed the terminal's capabilities must be disabled.

[0113] In one embodiment, when the terminal determines the availability of 4-step RACH and 2-Step RACH RA resource sets, after the RA resource sets are selected in a predetermined manner (see the embodiment described above regarding the paging-related scene), or after the RA resource sets including the RACH partition and common Rach are selected in a predetermined manner, further exclusions are performed according to the terminal's capabilities, and any available RA resource sets that are outside the terminal's capabilities are excluded.

[0114] In one embodiment, RA resource sets including partitioned RA resource sets and common RA resource sets may be selected for RACH using an existing method after first excluding them according to terminal capabilities.

[0115] Example 2: This example illustrates a method for determining the availability of a random access resource set.

[0116] For each group of a 4-step RA type configured random access resources (or resource sets, hereafter the same) and each group of a 2-step RA type configured random access resources (resource sets), the MAC entity should do the following:

[0117] If a RedCap directive is set for a group of random access resources (resource sets): The random access resources (resource sets) in this group are considered unavailable for random access procedures to which the RedCap directive does not apply.

[0118] When an SDT instruction is set for one group of random access resources (resource sets): The random access resources (resource sets) in this group are considered unavailable for random access procedures that are not triggered by small data transmissions (SDT).

[0119] If an NSAG directive is set for one group of random access resources (resource sets): The random access resources (resource sets) of that group are considered unavailable for random access procedures unless the random access resources of that group are triggered by the corresponding NSAG directive.

[0120] When an MSG3 iteration instruction is set for one group of random access resources (resource sets): If MSG3 iterations are not applied, the random access resources (resource sets) in that group are considered unavailable for use in random access procedures.

[0121] If none of the following are set for a group of random access resources (resource sets): Random access resources (resource sets) are considered not to be associated with any feature directives.

[0122] After completing the above steps, the following determination needs to be made for a specific type of device (for example, an R18 eRedcap user): In the case of R18 eRedcap, if the number of PUSCHs allocated for 2-step RACH access to a group of random access resources (resource sets) exceeds the bandwidth supported by R18 eRedcap, the random access resources (resource sets) in that group are considered unavailable for random access procedures.

[0123] Example 3: In Example 2, the procedure for selecting random access resources after determining the availability of a random access resource set according to an existing procedure may further exclude random access resource sets that are within the supported range of the terminal's capabilities, depending on the terminal's capabilities.

[0124] In other words, in the case of R18 eRedcap, if the number of PUSCH requests allocated to a 2-step RACH access for a group of random access resources (resource sets) exceeds the bandwidth supported by R18 eRedcap, the random access resources (resource sets) for that group are considered unavailable for random access procedures.

[0125] Whether R18 eRedcap applies this example to a single terminal depends on the instructions from the higher layer during random access.

[0126] Example 4: In one embodiment, when determining whether a terminal employs 4-step RACH or 2-step RACH, the terminal's capabilities must also be considered when selecting 2-step RACH.

[0127] In one embodiment, if the selected random access resource set includes 2-step and 4-step RA type random access resources (e.g., as specified in TS 38.321 Section 5.1.1b) in the BWP selected for the random access procedure, and the RSRP referenced by the downlink path loss is higher than msgA-RSRP-Threshold, and the UE's capability supports the selected 2-step random access resource set (e.g., the msgA PUSCH bandwidth in the resource set is within the terminal capability's supported range), or if the selected random access resource set includes only 2-step RA type random access resource sets in the BWP for the random access procedure, and the UE's capability supports the selected 2-step random access resource set (e.g., the msgA PUSCH bandwidth in the resource set is within the terminal capability's supported range), then RA_TYPE is set to 2-stepRA. Otherwise, RA_TYPE is set to 4-stepRA.
