[0021] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0022] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to capability reporting in mobile communications to improve the flexibility and efficiency of the communication system based on the layered structure of carrier and cell. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0023] As mentioned above, the layered structure of carrier and cell has been adopted in mobile communications to improve the communication quality. The carrier is a concept at the physical layer and serves as the frequency resource for signal transmission, while the cell belongs to the control layer and is configured to control the carrier and manage the connection of the UE. In 5G network architecture, the mapping relationship between the carrier and the cell is one-to-one, meaning that each physical carrier is controlled by a single cell to ensure efficient use of spectrum resources. This design enhances the precision of network management and improves network performance, making communication more stable.
[0024] The cell is responsible for managing the wireless resources of the carrier, including spectrum allocation, power adjustment, interference management, and scheduling strategies. Through Radio Resource Management (RRM) mechanisms, the network may dynamically adjust spectrum usage, such as modifying the carrier’s transmission power based on environmental needs, to ensure optimal coverage across different areas.
[0025] Additionally, the DSS technology allows 5G and LTE to flexibly allocate shared spectrum, preventing interference between networks. In the DSS architecture, the cell dynamically determines whether the spectrum is used for 5G or LTE based on real-time traffic demand. When 5G user traffic is high, the cell allocates more resources to the 5G carrier, whereas when a significant number of active LTE devices remain, the cell adjusts spectrum allocation to maintain balance.
[0026] The cell also employs dynamic load balancing techniques to manage network traffic distribution, ensuring that the carrier does not become congested and affect communication quality. When the carrier is under heavy traffic load, the cell can reassign user devices to a less congested carrier, maintaining a smooth network experience.
[0027] Beamforming and massive MIMO technologies further enhance the cell's ability to manage carrier resources and refine carrier management accuracy. The cell may dynamically adjust wireless signal direction using beamforming to ensure that carrier coverage aligns with user needs. Meanwhile, massive MIMO utilizes multiple antennas to improve spectrum efficiency, allowing multiple users to access the same carrier without interference.
[0028] In 6G communications, the super carrier (or referred to as multi-carrier cell) is introduced to further enhance the communication efficiency. One multi-carrier cell (i.e., one super carrier) is defined to be a cell that can be associated with one or multiple downlink / uplink (DL / UL) carriers (i.e., physical carriers) . Therefore, in the 6G network architecture, the mapping relationship between carrier and multi-carrier cell (super carrier) can be many-to-one. Note that in 5G communications, one cell is only associated with one DL / UL (physical) carrier.
[0029] FIG. 1 illustrates an example scenario 100 of multi-carrier cell deployment in accordance with implementations of the present disclosure. In scenario 100, there may be four multi-carrier cells (i.e., four super carriers) . The multi-carrier cell Cell_1 may be deployed in the Frequency Division Duplex (FDD) sub-3 frequency band. The multi-carrier cell Cell_2 may be deployed in the Time Division Duplex (TDD) sub-6 frequency band. The multi-carrier cell Cell_3 may be deployed in the 5G / 6G unlicensed band. The multi-carrier cell Cell_4 may be deployed in the Millimeter Wave (mmW) frequency band. Note that the depicted frequency ranges in drawings may not be accurately scaled.
[0030] As described above, the design of super carrier allows multiple carriers to map to one cell (i.e., the multi-carrier cell) , which differs from the 5G network architecture in which one carrier maps to one cell. As an example, the multi-carrier cell Cell_4 may be associated with 8 carriers (e.g., C1, C2, C3, C4, C5, C6, C7 and C8) and the multi-carrier cell Cell_2 may be associated with 3 carriers (e.g., C9, C10 and C11) . Therefore, there are 8 carriers mapped to the multi-carrier cell Cell_4 and 3 carriers mapped to the multi-carrier cell Cell_2.
[0031] The design of the multi-carrier cell aims to simplify the control procedure of the carriers and aggregate a wide spectrum range. As a multi-carrier cell can be associated with multiple carriers, the amount of control signaling and management overhead can be reduced. The reduction is more noticeable when the carriers have the same or similar properties, such as the 8 carriers associated with the multi-carrier cell Cell_4. In addition, the layered structure with the multi-carrier cell also lowers UE complexity and system overhead.
[0032] FIG. 2 illustrates an example scenario 200 of a receiver architecture in accordance with implementations of the present disclosure. In scenario 200, an Rx signal processing path Rx_0 is shown. The signal processing path Rx_0 may be a part of an Rx chain of the UE.
[0033] The signal received via the antenna ANT_0 of an apparatus (e.g., the UE) will be provided to the external low noise amplifier (eLNA) 201 and the internal LNA (iLNA) 202 for amplification, and then, after being frequency down-converted by the mixer 203, provided to the biquad (BQ) filter 204 for channel selection filtering.
[0034] FIG. 3 illustrates an example scenario 300 of another receiver architecture in accordance with implementations of the present disclosure. In scenario 300, two Rx signal processing paths Rx_1 and Rx_2 are shown. The signal received via the antenna ANT_1 of the UE will be provided to the eLNA 301 for amplification, and the eLNA 301 is shared by the two Rx signal processing paths Rx_1 and Rx_2. The signal processed by the eLNA 301 will be provided to both the iLNA 302-1 and the iLNA 302-2 for amplification. The iLNA 302-1 and the iLNA 302-2 are respectively arranged on the signal processing paths Rx_1 and Rx_2. The signals processed by the iLNA 302-1 will be provided to the BQ filter 304-1 for channel selection filtering after being frequency down-converted by the mixer 303-1. The signals processed by the iLNA 302-2 will be provided to the BQ filter 304-2 for channel selection filtering after being frequency down-converted by the mixer 303-2.
[0035] In scenario 300, the signal processing path Rx_1 may be a part of a first Rx chain of the UE, and the signal processing path Rx_2 may be a part of a second Rx chain of the UE. Assuming that the receiver architecture in scenario 300 is capable of supporting X MIMO layers and / or X-Rx diversity, the receiver architecture in scenario 200 is capable of supporting (X / 2) MIMO layer (s) and / or (X / 2) -Rx diversity since scenario 200 has half the number of Rx signal processing paths (half the number of Rx chains) compared to scenario 300, where X and (X / 2) are positive integers.
[0036] Because the UE’s radio frequency (RF) capability and receiver architecture design may determine the supportable band combinations, the supportable carrier combinations, the number of MIMO layers, and the number of Rx diversity, the UE’s capability information is suggested to be provided to the network node (e.g., a base station (BS) ) to facilitate the multi-carrier cell (super carrier) configuration.
[0037] This disclosure presents methods and apparatus for capability reporting to facilitate the utilization of the multi-carrier cell (i.e., the super carrier, hereinafter referred to as the 'multi-carrier cell' ) , thereby improving the flexibility and efficiency of the communication system.
[0038] In some implementations, for a given number of Rx chains (e.g., 1 or 2) of an apparatus (e.g., the UE) , the UE may report the supportable band combinations, the number of carriers, the number of MIMO layers, or the number of Rx diversity inside one multi-carrier cell.
[0039] After the report, the UE may receive a configuration from the BS for the designated operating band or carrier, the number of MIMO layers and / or the number of Rx diversity inside the multi-carrier cell. The UE may then arrange the baseband and / or RF signal processing resources during connection based on the configured numbers inside the multi-carrier cell.
[0040] In some implementations, an Rx chain may comprise one or more signal processing resources on the Rx signal processing path. For example, an Rx chain may comprise one or more RF front-end signal processing devices and one or more intermediate frequency (IF) signal processing devices, such as the devices depicted in FIG. 2 and FIG. 3. For another example, the Rx chain may further comprise one or more back-end signal processing devices, such as one or more baseband signal processing devices.
[0041] FIG. 4 illustrates an example scenario 400 of capability reporting in accordance with implementations of the present disclosure. The UE may determine a capability (UE capability) associated with a multi-carrier cell and report the UE capability to the BS. The UE capability may comprise at least one of one or more supportable band combinations, a number of supportable carriers, a number of supportable MIMO layers, and a number of supportable Rx diversity inside the multi-carrier cell.
[0042] As an example, assuming that the bands with indices #1 and #2 are FDD bands, the bands with indices #3 and #4 are TDD bands. The UE may report (#1, #2) as one band combination and (#3, #4) as another band combination, to inform the BS which bands can be bundled to form one multi-carrier cell.
[0043] After receiving the UE capability report, the BS may determine a configuration of the multi-carrier cell according to the UE’s capability and transmit the configuration to the UE. The configuration may comprise information regarding at least one of one or more designated operating bands, one or more designated operating carriers, a number of MIMO layers, and a number of Rx diversity inside the multi-carrier cell. The designated operating carriers are controlled and managed via the multi-carrier cell.
[0044] The UE may determine one or more signal processing resources according to the configuration. For example, the UE may determine or arrange one or more RF signal processing resources, one or more IF signal processing resources and / or one or more baseband signal processing resources during the connection based on the configured numbers inside the multi-carrier cell.
[0045] The UE may also report whether it supports carrier switching (e.g., fast DL carrier switching) to the BS. For example, the UE may report whether fast DL carrier switching is supported through a physical layer (layer 1) signaling or a medium access control (MAC) layer (layer 2) signaling, such as via a MAC control element (MAC-CE) . The fast DL carrier switching may happen inside a multi-carrier cell or across multiple multi-carrier cells based on the UE’s capability.
[0046] For another example, the UE capability reported to the BS may comprise a carrier switching capability, and the carrier switching capability may indicate whether a carrier switching inside the multi-carrier cell or across multiple multi-carrier cells is supported.
[0047] The BS may transmit an indication (e.g., a carrier switching indication) of performing the carrier switching through the physical layer signaling or the MAC layer signaling in an event that the carrier switching inside the multi-carrier cell or across multiple multi-carrier cells is supported by the UE. For example, the BS may use the Downlink Control Information (DCI) or the MAC-CE to instruct the UE to do fast DL carrier switching inside the multi-carrier cell or across multiple multi-carrier cells, based on the UE’s capability report. The UE may perform carrier switching in response to the carrier switching indication received from the BS.
[0048] In some implementations, the UE may further report the number and the frequency range of non-contiguous carriers supported by one Rx chain to the BS. For example, the UE may report the number and the frequency range of non-contiguous carriers supported by one Rx chain for each band or for each band combination.
[0049] After the report, the UE may receive a configuration from the BS for the number and the frequency range of non-contiguous carriers supported by one Rx chain, and may use the Rx chain to perform signal reception on these non-contiguous carriers.
[0050] In some implementations, the UE capability reported to the BS may comprise at least one of a number of non-contiguous carriers and a frequency range of non-contiguous carriers supported by an Rx chain. The UE may receive a configuration of the Rx chain from the BS. The configuration may comprise information regarding a number of designated non-contiguous carriers and / or a frequency range of one or more designated non-contiguous carriers associated with the Rx chain.
[0051] Based on the configuration, the UE may receive one or more signals from the BS on the one or more designated non-contiguous carriers via the Rx chain.
[0052] The UE may further report an allowed degradation value to the BS. The degradation value may be associated with signal reception on a plurality of non-contiguous carriers via an Rx chain, and may indicate the Signal-to-Noise Ratio (SNR) degradation or the noise raising value, where the SNR degradation may occur due to the noise raised up. For example, the allowed degradation value may be the delta reference sensing for intra-band non-contiguous configuration ΔRIBNC for FDD, or the delta reference sensing for intra-band non-contiguous configuration ΔRIBNC, TDD for TDD, caused by the shared Rx path. The degradation values may be different based on UE’s capabilities and the number of non-contiguous carriers supported by one Rx chain.
[0053] After the report, the BS may adjust its scheduling policy according to the degradation value, and the UE may receive one or more signals on the plurality of non-contiguous carriers via the Rx chain according to the degradation value as well.
[0054] For example, in an event that one or more signal receiving paths are shared for one Rx chain during the connection for multiple non-contiguous carriers, the UE may assume the reported degradation value (s) to perform signal reception on these carriers.
[0055] Regarding operations associated with the network node (e.g., the BS) , the BS may receive information regarding a capability (e.g., the UE capability report) from the UE and transmit a configuration to the UE. The capability may comprise at least one of one or more supportable band combinations, a number of supportable carriers, a number of supportable MIMO layers and a number of supportable Rx diversity inside the multi-carrier cell, and the configuration may comprise information regarding at least one of one or more designated operating bands, one or more designated operating carriers, a number of MIMO layers and a number of Rx diversity inside the multi-carrier cell.
[0056] The BS may further transmit an indication of performing the carrier switching (e.g., the carrier switching indication) to the UE through the physical layer or MAC layer signaling in an event that the carrier switching inside the multi-carrier cell or across multiple multi-carrier cells is supported by the UE.
[0057] The BS may further transmit a configuration of the Rx chain to the UE. The configuration may comprise information regarding a number of one or more designated non-contiguous carriers and / or a frequency range of the one or more designated non-contiguous carriers associated with UE’s Rx chain. The BS may transmit one or more signals to the UE on the one or more designated non-contiguous carriers, for the UE to receive the signals via its Rx chain.
[0058] The BS may further receive the degradation value report associated with signal reception on a plurality of non-contiguous carriers via the UE’s Rx chain. The BS may transmit one or more signals on the plurality of non-contiguous carriers according to the degradation value. Illustrative Implementations

[0084] The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0085] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application. The various singular / plural permutations may be expressly set forth herein for sake of clarity.
[0086] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”
