Description
METHODS AND APPARATUS FOR DEVICE COLLABORATION IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63 / 717,388, filed 07 November 2024, the content of which herein being incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to device collaboration in mobile communications.BACKGROUND
[0003] Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.
[0004] Multiple-input multiple-output (MIMO) is an antenna technology for wireless communications in which multiple antennas are used at both the source (e. g., transmitter) and the destination (e.g., receiver) . The antennas at each end of the communication apparatus are combined to minimize errors, optimize data throughput and improve the capacity of radio transmissions by enabling data to travel over many signal paths at the same time. Creating multiple versions of the same signal provides more opportunities for the data to reach the receiving antenna without being affected by fading, which improves the signal-to-noise ratio and error rate. By boosting the capability of radio frequency (RF) systems, MIMO technology can create a more stable connection, less congestion and high data throughput.
[0005] In a mobile communication system, if a UE could support a high number of MIMO layers, it could have diversity gain or multiplexing gain. However, the number of available MIMO layers is limited by channel quality between a network node (e.g., the base station (BS) or a next generation Node-B (gNB) ) and the UE. In addition, hardware and / or software limitations and power limitations of the UE could also limit the MIMO capability of the UE. Therefore, if there is another UE-controlled device (e.g., a collaborative UE, a relay, or a repeater that may act as an external antenna panel wirelessly connected to the UE) that could help forward the data / signaling via another frequency, it could increase the effective number of MIMO layers and boost the MIMO performance significantly.
[0006] To support data forwarding, the Uu interface data in frequency f1 (or frequency band #1) is forwarded between a primary UE and the collaborative UE by using frequency f2 (or frequency band #2) . The collaborative UE may perform data forwarding with frequency translation (FT-forwarding) between frequency band #1 and frequency band #2 with nearly zero latency. However, transmission in frequency band #2 may unavoidably suffer interference with existing legacy systems operating in the same band.
[0007] Accordingly, how to mitigate or avoid interference caused by transmission in frequency band #2 is an important issue for the newly developed wireless communication network.SUMMARY

[0022] 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
[0023] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to device collaboration and associated criteria for enabling device collaboration in mobile communications. 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.
[0024] FIG. 1 illustrates an example scenario 100 under schemes in accordance with implementations of the present disclosure. Scenario 100 involves at least a primary UE and a collaborative UE supporting device collaborative communications, and a network node, which may be a part of a wireless communication network (e.g., an LTE network, a 5G / NR network, an IoT network or a 6G network) . Scenario 100 illustrates the framework of device collaboration and the associated data forwarding operation in a communication system. The primary UE may expand its MIMO capability (e.g., effective number of MIMO layers) through device collaboration, wherein data is forwarded via the collaborative UE. In the implementations, the device collaboration involves collaborative transmission (Tx) and reception (Rx) .
[0025] Specifically, the primary UE may directly communicate with the network node (e.g., gNB) on a first frequency f1 (or in a first frequency band #1, for example, in a licensed band) . The first frequency f1 may comprise a low band or a mid-band frequency (e.g., frequency range 1 (FR1) ) , which has wide area coverage and is suitable for long-range communication. In addition to the direct communication with the network node, the primary UE may establish an indirect communication with the network node via the collaborative UE. The collaborative UE may communicate with the primary UE via a local link on a second frequency f2 (or in a second frequency band #2, for example, in a licensed band or an unlicensed band) . The second frequency f2 may comprise a mid-band or a high-band frequency (e.g., FR2 or FR3) , which has a high data rate and is suitable for short-range communication. For long-range communication, the collaborative UE may also communicate with the network node in the first frequency f1 (or in a first frequency band #1) . Thus, the collaborative UE may perform an inter-band frequency translation or conversion to translate or shift the first frequency f1 in the first frequency band #1 into the second frequency f2 in the second frequency band #2, or translate or shift the second frequency f2 in the second frequency band #2 into the first frequency f1 in the first frequency band #1.The collaborative UE may help forward the data transmission between the primary UE and the network node. The data forwarding performed by the collaborative UE may comprise the layer 1 (L1) forwarding and / or the layer 2 (L2) forwarding. For example, the collaborative UE may perform amplify-and-forward with frequency translation between band #1 and band #2 with nearly zero latency to support data forwarding (i.e., the FT-forwarding) . It is noted that the frequency band mentioned above is an interval of radio frequencies, and is not limited to “band” specifically defined by organizations such as 3GPP.
[0026] In some implementations, a control interface may be established between the primary UE and the collaborative UE. The primary UE may provide control information regarding the data forwarding (FT-forwarding) operations to the collaborative UE via the control interface. The control information may comprise, for example, and without limitation, the on or off status of the data forwarding operations, band #1 configuration information, band #2 configuration information, Tx power in band #1, Tx power in band #2, etc.
[0027] As mentioned above, the collaborative UE may communicate with the primary UE via a local link on the second frequency f2. In the scenarios involving device collaborative communications, if other UEs are simultaneously communicating with the network node on the same f2 frequency, unintended interference may occur.
[0028] FIG. 2 illustrates an example scenario 200 under schemes in accordance with implementations of the present disclosure. In scenario 200, the primary UE may directly communicate with the network node (e.g., gNB) in a first frequency band #1 (or on a first frequency f1) , and may establish an indirect communication with the network node via the collaborative UE in a second frequency band #2 (or on a second frequency f2) . The first frequency band #1 may be a licensed band, and the second frequency band #2 may be a licensed band or an unlicensed band.
[0029] Assuming that the network node also communicates with other UEs (e.g., UE 1 and UE 2 as shown in FIG. 2) over the frequency band #2, unintended interference may occur. For example, communication between the primary UE and the collaborative UE over the frequency band #2 may introduce interference to UE1, which may act as a victim UE in this scenario.
[0030] To address this issue, various techniques, methods, schemes and / or solutions, along with corresponding criteria (or trigger conditions) , for enabling device collaboration in mobile communications are proposed.
[0031] In the implementations of the present disclosure, the UE (e.g., the primary UE) may receive a configuration from a network node (e.g., BS or gNB) in a first frequency band. The configuration may indicate a second frequency band which is different from the first frequency band. In some implementations, the configuration may indicate at least one frequency resource in the second frequency band. The UE may determine whether to request the network node to activate a transmission mode utilizing the second frequency band according to the configuration.
[0032] In some implementations, the configuration may be transmitted for measuring the receiving power in the second frequency band, and the criteria for enabling device collaboration utilizing the second frequency band may be associated with the receiving power. In some implementations, the configuration may further indicate at least one measurement resource associated with the frequency resource, such as a signal to be measured, the time or frequency resource associated with the signal, or others.
[0033] In some implementations, the UE may measure the receiving power of the signal in the second frequency band according to the configuration, and determine whether to request the network node to activate the transmission mode according to one or more criteria. For example, the UE may determine to request the network node to activate the transmission mode in an event that the receiving power is lower than a threshold. In some implementations, in an event that the receiving power is not lower than the threshold, the UE may determine not to request the network node to activate the transmission mode. Instead of operating in the transmission mode, the UE may determine to operate with two component carriers (2CC) via carrier aggregation by combining frequency resources from the first frequency band and the second frequency band, to enhance transmission bandwidth and throughput in an event that the receiving power is not lower than the threshold.
[0034] In some implementations, the receiving power and the threshold may correspond to metrics such as the Reference Signal Received Power (RSRP) , the Reference Signal Received Quality (RSRQ) , or similar measurements. In some implementations, the UE may receive information regarding the threshold from the network node.
[0035] In some implementations, the signal measured by the UE may be transmitted by the network node and may comprise a wideband signal or a reference signal. For example, the signal may be a wideband signal within a specific channel bandwidth in the second frequency band. For another example, the signal may be a known signal or a reference signal within a specific channel bandwidth in the second frequency band, such as a synchronization signal.
[0036] In an event that the UE determines to request the network node to activate the transmission mode, the UE may transmit a request to the network node to activate the transmission mode. In some implementations, the UE may select at least one frequency resource on which the receiving power is lower than the threshold, and the request may comprise information regarding the selected frequency resource. In some other implementations, the request may comprise information regarding at least one measurement result associated with the frequency resource indicated in the configuration. The measurement result may comprise one or more values representing the receiving power (for example, the RSRP, the RSRQ, the RSSI, or the like) , one or more frequency resources that meet the criteria for activating or enabling device collaboration, or one or more frequency resources with relatively lower or the lowest measured value (s) of receiving power. In such implementations, the network node may select a frequency resource in the second frequency band based on the measurement result. For example, the network node may select at least one frequency resource on which the receiving power measured by the UE is lower than the threshold.
[0037] The UE may receive an indication of activating the transmission mode utilizing the second frequency band from the network node in an event that the network node acknowledges, permits or authorizes the use of a selected frequency resource. Upon receiving the indication, the UE may further determine whether to actually enable the transmission mode. The transmission mode (as well as the external antenna panel provided by the collaborative UE) may be disabled by default. In an event that the transmission mode is enabled, the UE may transmit or receive a first radio frequency (RF) signal carrying a data signal to or from the network node in the first frequency band, and transmit or receive a second RF signal carrying the data signal to or from a collaborative apparatus (e.g., the collaborative UE) in the second frequency band. In some implementations, the UE doesn’ t expect the transmissions or receptions in the first frequency band and the second frequency band are from or to the same node. In some implementations, the UE may also determine not to enable the transmission mode, even upon receiving an indication from the network node. For example, when the UE detects that the collaborative UE is in a low power condition.
[0038] From the network node’s perspective, the network node may transmit a configuration to the UE in a first frequency band. The configuration may indicate a second frequency band which may be different from the first frequency band. The configuration may also indicate at least one frequency resource and / or at least one measurement resource associated with the frequency resource in the second frequency band.
[0039] The network node may further receive a request to activate a transmission mode utilizing the second frequency band from the UE and determine whether to activate the transmission mode according to the request.
[0040] In some implementations, the network node may transmit a signal in the second frequency band and in the frequency resource indicated in the configuration, and the request received from the UE may comprise information regarding a measurement result associated with the frequency resource or a selected frequency resource. In some implementations, the signal transmitted by the network node may comprise a wideband signal, a known signal or a reference signal.
[0041] In some implementations, the network node may also transmit information regarding a threshold for determining whether the transmission mode can be activated or enabled to the UE. In some implementations, the request received from the UE may comprise information regarding the frequency resource selected by the UE with the receiving power lower than the threshold. The network node may determine the threshold based on reasonable operation points and / or locations of the UEs performing device collaboration.
[0042] In some implementations, the measurement result provided by the UE may comprise one or more values representing the receiving power of the signal transmitted in the second frequency band, one or more frequency resources that meet the criteria for activating or enabling device collaboration, or one or more frequency resources with relatively lower or the lowest measured value (s) of the receiving power. The network node may select at least one frequency resource in the second frequency band based on the measurement result. For example, the network node may select at least one frequency resource on which the receiving power is lower than the threshold.
[0043] When the network node determines to activate the transmission mode, the network node may transmit an indication of activating the transmission mode to the UE.
[0044] In some implementations, the UE and / or the network node may determine whether to activate or enable the transmission mode associated with device collaboration based on predefined criteria or trigger conditions as introduced above, ensuring that such collaboration does not interfere with legacy operations within the same band.
[0045] In some implementations, the network node may further transmit an indication of a scheme used for data transmission or reception by utilizing the external antenna panel provided by the collaborative UE. The scheme candidates may comprise link combining, link selection or no-forwarding. When the link combining scheme is indicated, the signals received by the UE via the direct link (i.e., the direct communication) and the indirect link (i.e., the indirect communication) may be combined. When the link selection scheme is indicated, the UE may select either the direct link or the indirect link. When the no-forwarding scheme is indicated, the UE is expected to receive signals only via the direct link.
[0046] FIG. 3 illustrates an example scenario 300 of an operation flow of enabling device collaboration in accordance with implementations of the present disclosure. The primary UE may communicate with the network node and enter the Radio Resource Control (RRC) connected (RRC_CONNECTED) mode to initiate dedicated signaling and data transmission procedures.
[0047] The primary UE may also communicate with the collaborative UE via a wireless communication protocol, such as Wi-Fi or Bluetooth. The primary UE or the collaborative UE may perform a device discovery and association procedure to enable communication with each other.
[0048] The network node may transmit a configuration, such as a white list for the frequency f2 in the second frequency band or a white list for frequencies or bands reserved for the data forwarding operation (denoted as “white list for f2” in FIG. 3) , to the primary UE. The configuration or the white list for f2 may be provided via broadcast or RRC signaling. In some implementations, the white list for f2 may comprise a list of candidate frequencies or a list of candidate frequency resources for device collaboration. In addition, in some implementations, the white list for f2 may include a limitation on maximum Tx power.
[0049] The primary UE may determine whether to request the network node to activate the transmission mode associated with device collaboration according to the white list for f2 (i.e., the configuration) . For example, the UE may select at least one frequency or at least one frequency resource based on the white list for f2 in the determination step.
[0050] In an event that the primary UE determines to request the network node to activate the transmission mode associated with device collaboration utilizing a selected frequency or frequency resource, the primary UE may transmit a request (denoted as “Activation Request” in FIG. 3) to the network node to activate the transmission mode utilizing the second frequency band as mentioned above. The request may comprise information regarding the selected frequency or selected frequency resource.
[0051] In an event that the network node determines to activate the transmission mode, or the network node permits or authorizes transmission on the selected frequency or selected frequency resource, the network node may transmit an indication of activating the transmission mode utilizing the second frequency band to the UE (denoted as “Activation Indication” in FIG. 3) .
[0052] Upon receiving the indication, the primary UE may determine whether to enable the transmission mode. In an event that the primary UE determines to enable the transmission mode, the primary UE may provide necessary information associated with device collaboration, such as information regarding the selected frequency or selected frequency resource, to the collaborative UE. The primary UE may provide the information via the control interface. Note that in some implementations aimed at minimizing signaling between the primary UE and the network node, the “Activation Request” and “Activation Indication” messages may be omitted.
[0053] In an event that the transmission mode is enabled, the data forwarding may be turned on or enabled, and the primary UE may transmit an indication of capability update to the network node (denoted as “Capability Update” in FIG. 3) . For example, the primary UE may update its maximum MIMO layer via the indication. As the collaborative UE may act as an external antenna panel wirelessly connected to the primary UE, the antenna capability of the primary UE may be augmented, and thus the capability of the primary UE may be updated when the data forwarding at the collaborative UE is turned on or enabled.
[0054] In the downlink direction, the primary UE may receive a Channel State Information (CSI) reference signal (CSI-RS) to perform CSI measurements for downlink channel estimation, or receive data (e.g., via the Physical Downlink Shared Channel (PDSCH) ) from the network node. In an event that the transmission mode is enabled, the collaborative UE may also receive the CSI-RS or the data via PDSCH and forward the received CSI-RS or data to the primary UE with frequency translation (i.e., the FT-forwarding) .
[0055] Regarding the uplink scenario, the primary UE may transmit Sounding Reference Signal (SRS) for uplink channel estimation, or transmit data via Physical Uplink Shared Channel (PUSCH) to the network node. In an event that the transmission mode is enabled, the collaborative UE may also receive the SRS or data from the primary UE and forward the received SRS or data to the network node with frequency translation (i.e., the FT-forwarding) .
[0056] FIG. 4 illustrates an example scenario 400 of an operation flow of enabling device collaboration in accordance with implementations of the present disclosure. The primary UE may communicate with the network node and enter the RRC_CONNECTED mode to initiate dedicated signaling and data transmission procedures.
[0057] The primary UE may also communicate with the collaborative UE via a wireless communication protocol, such as Wi-Fi or Bluetooth. The primary UE or the collaborative UE may perform a device discovery and association procedure to enable communication with each other.
[0058] The primary UE may transmit a device collaboration request to the network node to request authorization or permission for device collaboration.
[0059] The network node may transmit a configuration for measuring the receiving power of a signal in the second frequency band to the primary UE. The configuration may indicate one or more frequency resources and / or one or more measurement resources associated with the frequency resources in the second frequency band. The primary UE or the network node may identify which of or whether the one or more frequency resources is suitable for device collaboration.
[0060] The primary UE may perform measurement based on the configuration. For example, the primary UE may measure the receiving power of a signal transmitted in the second frequency band and obtain one or more measurement results according to the configuration in the measurement step. In some implementations, the signal measured by the UE may be transmitted by the network node.
[0061] In some implementations, the primary UE may further determine whether the measured receiving power is lower than a threshold. For example, the UE may select at least one frequency or at least one frequency resource on which the receiving power is lower than the threshold based on the measurement results. The primary UE may determine to request the network node to activate the transmission mode in an event that the receiving power measured on at least one frequency or at least one frequency resource in the second frequency band is lower than the threshold.
[0062] In an event that the primary UE determines to request the network node to activate the transmission mode associated with device collaboration in a selected frequency or frequency resource, the primary UE may transmit a request (denoted as “Activation Request” in FIG. 4) to the network node to activate the transmission mode as mentioned above. The request may comprise information regarding the selected frequency or selected frequency resource.
[0063] In some implementations, the request may comprise information regarding the measurement results. The network node may select a frequency or frequency resource in the second frequency band based on the measurement results in the determination step. For example, the network node may select at least one frequency or frequency resource on which the receiving power is lower than the threshold.
[0064] In an event that the network node determines to activate the transmission mode associated with device collaboration utilizing the second frequency band or the network node permits or authorizes transmission utilizing the second frequency band or on the selected frequency or selected frequency resource, the network node may transmit an indication of activating the transmission mode utilizing the second frequency band to the UE (denoted as “Activation Indication” in FIG. 4) . In some implementations, the indication may go with limitation on maximum Tx power. In an event that the frequency or frequency resource is selected by the network node, the indication may comprise information regarding the selected frequency or selected frequency resource.
[0065] Upon receiving the indication, the primary UE may determine whether to enable the transmission mode. In an event that the primary UE determines to enable the transmission mode, the primary UE may provide necessary information associated with device collaboration, such as information regarding the selected frequency or selected frequency resource, to the collaborative UE. The primary UE may provide the information via the control interface.
[0066] In an event that the transmission mode is enabled, the data forwarding may be turned on or enabled, and the primary UE may transmit an indication of capability update to the network node (denoted as “Capability Update” in FIG. 4) . For example, the primary UE may update its maximum MIMO layer for reception or transmission via the indication. As the collaborative UE may act as an external antenna panel wirelessly connected to the primary UE, the antenna capability of the primary UE may be augmented, and thus the capability of the primary UE may be updated when the data forwarding at the collaborative UE is turned on or enabled.
[0067] Similarly, in the downlink direction, the primary UE may receive a CSI-RS to perform CSI measurements for downlink channel estimation, or receive data (e.g., via the PDSCH) from the network node. In an event that the transmission mode is enabled, the collaborative UE may also receive the CSI-RS or the data via PDSCH and forward the received CSI-RS or data to the primary UE with frequency translation (i.e., the FT-forwarding) .
[0068] Regarding the uplink scenario, the primary UE may transmit SRS for uplink channel estimation or transmit data via PUSCH to the network node. In an event that the transmission mode is enabled, the collaborative UE may also receive the SRS or data from the primary UE and forward the received SRS or data to the network node with frequency translation (i.e., the FT-forwarding) .
[0069] In some implementations, the network node may request the primary UE to terminate or deactivate the device collaboration. In some implementations, the primary UE may actively terminate or deactivate the device collaboration and inform the network node of the termination or deactivation via an indication of capability update.

[0098] 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.
[0099] 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.
[0100] 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. ”
