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.

[0099] 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.

[0100] 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).

[0101] 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.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0104] In some embodiments, the introduction of 2Rx non-REDCAP XR devices is intended to take into account that for some frequency bands that are mandatory to support 4 antennas (4RX), 4 antennas will not be able to be placed due to the miniaturization of XR devices. Therefore, a new 2RX terminal will be introduced, with the purpose of reducing the number of antennas in devices that are mandatory to support 4RX bands, that is, introducing a 2-antenna XR device. At the same time, in order to distinguish it from the original 2RX capacity-reduced Redcap terminal, it is named '2Rx non-REDCAP XR devices'.

[0105] In some embodiments, the network supports 2RX XR terminals by default, that is, access is not allowed only when the network explicitly notifies the terminal that the cell does not support 2RX XR terminals.

[0106] In some embodiments, because the support of 2RX XR terminal capabilities is per band (based on band configuration), that is, some bands in a cell are supported and some bands are not. For example, a terminal is a 2RX XR terminal on band 1 of a cell, but is still a normal terminal (i.e., a 4RX terminal) on band 2; in the relevant scenario, the terminal is allowed to access a cell set with cellBarred2RxXR, because it can access as a 4RX terminal at this time, but because the terminal will continue to check whether it supports the frequency band indicated in frequencyBandList and the terminal will select the first frequency band in the frequency band list of the cell that supports its transmission requirements. Then, when the terminal selects band 1 to determine the transmission requirements, it finds that the terminal does not support band 1 or the terminal finds that band 2 cannot be supported at this time. Therefore, it still cannot continue to work in this cell. Therefore, when making subsequent determinations based on the band, it is still necessary to consider the terminal's support for the band. Therefore, it is necessary to consider a solution to this problem.

[0107] FIG2a is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to a communication method for a communication system 100, the method comprising:

[0108] Step S2101: The terminal performs the first type of operation.

[0109] In some embodiments, the terminal performs a first type of operation based on the first information of the terminal.

[0110] In some embodiments, the first information is used to indicate that the terminal supports or does not support a first feature on a first frequency band.

[0111] In some embodiments, the first characteristic is that the terminal is a service terminal with 2 antennas and 2 RX.

[0112] In some embodiments, the first characteristic is that the terminal is an extended reality terminal with 2 antennas and 2RX.

[0113] In some embodiments, the first type of operation includes: admission control operation of access cell.

[0114] In some embodiments, the configuration granularity for configuring the terminal to support or not support the first feature is frequency band.

[0115] For example, on band 0, the terminal supports the first feature, but on band 1, the terminal does not support the first feature.

[0116] In some embodiments, the first category of operations includes a first operation.

[0117] In some embodiments, the first operation is performed based on the first information of the terminal.

[0118] In some embodiments, the first operation is performing an admission control operation for accessing the cell according to a frequency band list frequencyBandList indicated by the cell.

[0119] In some embodiments, the first frequency band is a frequency band indicated by a cell.

[0120] Exemplarily, the first operation is to consider the situation of XR terminals supporting 2RX on at least one or more bands indicated by the cell when determining the frequencyBandList indicated by the cell, so as to determine whether access to the cell is allowed (that is, when the first operation is determined, it is not prohibited (bar) before subsequent operations can be continued; otherwise, the cell is deemed to be barred and subsequent operations cannot be performed).

[0121] In some embodiments, the first operation is performed based on the first information and the second information.

[0122] In some embodiments, the second information is used to indicate whether the cell barring 2-antenna 2RX service cellBarred2RxXR information field exists or does not exist.

[0123] In some embodiments, it is determined that the terminal supports the first feature on the first frequency band and the cellBarred2RxXR information field is not configured, and the first operation is performed.

[0124] For example, if the terminal supports the first feature on the band and is a 2Rx XR UE, it is necessary to determine that cellBarred2RxXR does not exist before it can be considered as an XR terminal supporting 2RX on at least one or more indicated bands and subsequent operations (for example, the second operation) can be continued.

[0125] In some embodiments, determining to perform a second operation is based on first information of the terminal to perform the first type of operation.

[0126] In some embodiments, the second operation includes at least one of the following: selecting a first frequency band indicated by a first instance in the frequencyBandList indicated by the cell; determining whether the first frequency band meets a first condition, wherein the first condition is a condition associated with a transmission requirement; the first frequency band is a frequency band indicated by the cell.

[0127] Exemplarily, the subsequent operation (e.g., the second operation) includes the terminal selecting the frequency band indicated by the first entity (instance) in the frequencyBandList indicated by the cell, and using this to determine whether it is necessary to consider whether the emission requirements are met on the indicated band; wherein the emission requirements refer to whether the terminal supports at least one of the indicated additional spectrum emission values.

[0128] In some embodiments, the first type of operation is performed based on the first information and the second information of the terminal.

[0129] In some embodiments, the second information is used to indicate whether the cell barred 2-antenna service cellBarred2RxXR information field exists or does not exist.

[0130] In some embodiments, it is determined that the terminal supports the first feature on the first frequency band and the cellBarred2RxXR information field is not configured, and the first type of operation is performed.

[0131] Exemplarily, the terminal selects the frequency band indicated by the first entity in the frequencyBandList indicated by the cell, and uses this to determine whether it is necessary to consider whether the emission requirements are met on the indicated band. The emission requirement refers to whether the terminal supports at least one of the indicated additional spectrum emission values. At this time, if the terminal supports a 2Rx XR UE on this band, then cellBarred2RxXR does not need to exist before it can be considered that the terminal supports 2RX on the first indicated band (corresponding to the first feature) or the cell is not bar before subsequent operations can be continued.

[0132] In some embodiments, the first condition is that the terminal supports at least one of the indicated power transmission values.

[0133] In some embodiments, during the determination of a Supplementary Uplink (SUL) carrier, a first type of operation is performed based on first information of the terminal.

[0134] In some embodiments, the terminal is a 2-antenna non-REDCAP XR device.

[0135] Step S2102: The terminal performs intra-frequency cell reselection.

[0136] In some embodiments, the terminal performs intra-frequency cell reselection according to the communication protocol information.

[0137] In some embodiments, it is determined that the execution of the first type of operation fails, and intra-frequency cell reselection is performed according to the communication protocol information.

[0138] In some embodiments, a first type of operation is performed based on first information of the terminal; if it is determined that the execution of the first type of operation fails, intra-frequency cell reselection is performed according to the communication protocol information.

[0139] It should be noted that if it is determined that the cell is barred and it is set to not allow processing according to intraFreqReselection2RxXR, the terminal is not allowed to reselect the same-frequency cell.

[0140] In some embodiments, the term "information" can be interchangeable with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0141] In some embodiments, the term "send" can be interchanged with terms such as "transmit", "report", and "transmit".

[0175] In some embodiments, the terminal is a 2-antenna non-REDCAP XR device.

[0176] In order to better understand the embodiments of the present disclosure, the present disclosure is further described below through an exemplary embodiment:

[0177] Example 1:

[0178] In some embodiments, the present disclosure protects a method for a specific type of terminal admission control.

[0179] In some embodiments, the support capability of a specific type of terminal for a specific service is per band.

[0180] In some embodiments, a specific service is access by an XR terminal of 2RX.

[0181] In one embodiment, after the terminal determines that the cell does not bar the user according to the cellBarred2RxXR switch, it needs to further determine whether it supports at least one or more cell-specified frequency bands (at least one frequency band that is indicated in the frequencyBandList of the cell) and whether it supports the emission requirements of the first frequency band (the first frequency band in the frequencyBandList for which the UE supports its emission requirement). Only if these are passed can it be considered accessible. Otherwise, it needs to be processed according to cellbar. Among them, further determining whether to support at least one or more cell-specified frequency bands (at least one frequency band that is indicated in the frequencyBandList of the cell) is the first operation decision process; and whether to support the emission requirements of the first frequency band (the first frequency band in the frequencyBandList for which the UE supports its emission requirement) is the second operation decision process. In both decision processes, the terminal's support capability for a specific band needs to be considered.

[0182] In one embodiment, if the terminal is a 2RX XR terminal on a specified band, cellBarred2RxXR needs to not exist at the same time; otherwise, the cell is considered to be bar.

[0183] In some embodiments, when performing the first operation, the terminal needs to consider the terminal's support capability for a specific band:

[0184] Exemplarily, when the first operation is to determine the frequencyBandList indicated by the cell, it is necessary to consider the XR terminal that supports 2RX on at least one or more of the indicated bands to decide whether to allow access to the cell (corresponding to performing the first type of operation).

[0185] For example, if the terminal supports a 2RX XR UE on the band, then the cellBarred2RxXR does not need to exist before it can be considered as an XR terminal supporting 2RX on at least one or more of the indicated bands. Otherwise, the cell is considered to be a cell barred cellbar. If this step is judged to be successful (i.e., the characteristic of the XR terminal supporting 2RX), subsequent operations (e.g., the second operation) can be continued.

[0186] Exemplarily, the subsequent operation (e.g., the second operation) includes the terminal selecting the frequency band indicated by the first entity in the frequencyBandList indicated by the cell, and using this to determine whether it is necessary to consider whether the emission requirements are met on the indicated band; wherein the emission requirement refers to whether the terminal supports at least one of the indicated power emission values ​​(at least one of the additionalSpectrumEmission values).

[0187] In some embodiments, when the terminal performs the second operation, it is necessary to consider the terminal's support capability for a specific band:

[0188] For example. The terminal selects the frequency band indicated by the first entity in the frequencyBandList indicated by the cell, and uses this to determine whether it is necessary to consider whether the emission requirements are met on the indicated band. The emission requirement refers to whether the terminal supports at least one of the additionalSpectrumEmission values ​​indicated; at this time, if the terminal supports a 2Rx XR UE on this band, then cellBarred2RxXR does not need to exist before it can be considered that the XR terminal supports 2RX on the first band indicated. If this step is judged to be passed (that is, the characteristics of the XR terminal supporting 2RX), subsequent operations can be performed. Otherwise, the cell is considered to be a cell that prohibits cellbar processing.

[0189] In some embodiments, in the above example, if in the above execution process, after the first operation or the second operation is judged, if it is not satisfied (that is, the characteristics of the XR terminal that does not support 2RX), it can be considered that the cell is barred. At this time, the intraFreqReselection2RxXR is set to not allow processing, that is, the same-frequency cell reselection is not allowed for processing.

[0190] In the above embodiment, the corresponding mechanism will not cause the situation mentioned in the background art where the terminal first accesses a cell that does not allow 2RX users to access as a 4RX terminal and then fails to work on the specific selected band.

[0191] In some embodiments, the decision principle for the first operation or the second operation may be used in the decision process for the SUL carrier.

[0192] In some embodiments, the terminal is first judged to support 2RX on at least one or more of the indicated bands as an XR terminal. That is, if the terminal is an XR terminal that supports 2RX on the specified band, then cellBarred2RxXR does not need to exist before it can be considered as an XR terminal that supports 2RX on at least one or more of the indicated bands. This judgment condition can be used together with other judgment conditions. For example, it is judged whether the TDD or FDD frequency band configured by the base station is supported. If the above is passed, the subsequent judgment will continue, otherwise it is considered that the cell is bar. (That is, the first operation judgment process).

[0193] An embodiment of the first operation decision process is given below:

[0194] Branch 1 is: if the UE supports one or more frequency bands indicated in the frequency band list for downlink of Time Division Duplexing (TDD), or one or more frequency bands indicated in the frequency band list for uplink of Frequency Division Duplexing (FDD), and they are not downlink-only bands, and if the UE is a 2Rx XR UE on the frequency band and cellBarred2RxXR does not exist, and if the UE is not a RedCap UE, or if the UE is a RedCap UE and halfDuplexRedCapAllowed exists, or if the UE is a RedCap UE and the RedCap UE supports full-duplex FDD operation on the frequency band;

[0195] Alternatively, branch 1 is: if the UE supports one or more frequency bands indicated in the frequency band list for the downlink of time division duplexing (TDD), or one or more frequency bands indicated in the frequency band list for the uplink of frequency division duplexing (FDD), and they are not downlink-only frequency bands, and if the UE is not a RedCap UE or a none-Redcap user of 2RX, or if the UE is a RedCap UE and halfDuplexRedCapAllowed exists, or if the UE is a RedCap UE and the RedCap UE supports full-duplex FDD operation on the frequency band, or if the UE is a 2Rx XR UE on the frequency band and cellBarred2RxXR does not exist, then:

[0196] Then: execute branch 1-1 and / or branch 1-2, that is, apply the channel bandwidth supported by the uplink or downlink.

[0197] In some embodiments, branch 1-1 is: applying a supported uplink channel bandwidth having a maximum transmission bandwidth, the maximum transmission bandwidth being:

[0198] Exemplarily, the SCS contained in the carrier bandwidth indicated in uplinkConfigCommon, for the initial uplink BWP, or for (e)REDCap UEs, the initial uplink BWP specific to RedCap (if configured), and greater than or equal to the bandwidth of the initial BWP for the uplink, or for (e)RedCap UEs, greater than or equal to the bandwidth of the initial uplink BWP specific to RedCap (if configured);

[0199] In some embodiments, branch 1-2 is: applying a supported downlink channel bandwidth with a maximum transmission bandwidth of:

[0200] Exemplarily, contained within the carrier bandwidth indicated in the downlinkConfigCommon of the SCS for the initial downlink BWP, or for (e)REDCap UEs, the initial downlink BWP specific to RedCap (if configured), and greater than or equal to the bandwidth of the initial BWP for the downlink, or for (e)RedCap UEs, greater than or equal to the bandwidth of the initial downlink BWP specific to RedCap (if configured).

[0201] An embodiment of the second operation decision process is given below:

[0202] In some embodiments, after branch 1, the first frequency band in the frequency band list is selected (for FDD, selected from the frequencyBandList for uplink, or for TDD, selected from the frequencyBandList for downlink), the UE supports and the UE supports at least one of the additional spectrum emission values ​​in nr-NS-PmaxList (if any), and for REDCap UE, if halfDuplexRedCapAllowed does not exist, or the UE supports full-duplex FDD operation, or for the UE that supports 2Rx XR in the frequency band, and cellBarred2RxXR does not exist (corresponding to the second operation decision process), then subsequent operations are performed, such as reading system messages, etc.

[0203] In some embodiments, if during the above execution process, the first operation or the second operation is not satisfied after the judgment: the cell is considered to be prohibited; the intra-frequency cell reselection is performed when intraFreqReselection, intraFreqReselectionRedCap of REDCAP UE, intraFreqReselection-eRedCap of EREDCAP UE or intraFreqReselection2RxXR of 2RX XR UE is set to notAllowed.

[0204] For SUL, an embodiment of the first operation decision process is given below:

[0205] In some embodiments, for SUL determination, the terminal is first determined to be on at least one or more indicated bands. That is, if the terminal is an XR terminal supporting 2RX on the specified band (indicated in the frequencyBandList for the supplementaryUplink), and cellBarred2RxXR does not exist, then subsequent operations are performed. Otherwise, the cell is processed according to cellbar. (Corresponding to the first operation determination process).

[0206] For SUL, an embodiment of the second operation decision process is given below:

[0207] In some embodiments, for SUL judgment, the first frequency band in the frequency band list (the first frequency band in the frequencyBandList for the supplementaryUplink) is selected, which the UE supports and the UE supports at least one of the additional spectrum emission values ​​in nr-NS-PmaxList (if any), and for REDCap UE, if halfDuplexRedCapAllowed does not exist, or the UE supports full-duplex FDD operation, or for UE that supports 2Rx XR in the frequency band, and cellBarred2RxXR does not exist, subsequent operations are performed, otherwise the cell is processed according to cellbar.

[0208] In some embodiments, if in the above execution process, after the first operation or the second operation is judged, if it is not satisfied, the cell is considered to be prohibited; the intra-frequency cell reselection will be performed when the intraFreqReselection, or the intraFreqReselectionRedCap of the REDCAP UE, or the intraFreqReselection-eRedCap of the EREDCAP UE, or the intraFreqReselection2RxXR of the 2RX XR UE is set to notAllowed.

[0209] In some embodiments, if during the above execution process, after the first operation or the second operation is judged, if the conditions are met, subsequent operations are performed, such as applying the channel bandwidth supported by the uplink or downlink or obtaining system information.
