Description

Technical Field

[0001] This invention relates to mobile communications, and more particularly to the switching control of data forwarding operations of cooperative user equipment (UE) in mobile communications. Background Technology

[0002] Unless otherwise indicated, the methods described in this section are not prior art to the claims and are not acknowledged as prior art by virtue of their inclusion in this section.

[0003] Multiple-input multiple-output (MIMO) is an antenna technique for wireless communication that uses multiple antennas at both the signal source (e.g., transmitter) and the signal receiver (e.g., receiver). The two antennas at opposite ends of the communication device are combined to minimize errors, optimize data throughput, and increase the capacity of radio transmission by enabling data to be transmitted simultaneously through multiple signal paths. Creating multiple versions of the same signal provides more opportunities for data to reach the receiving antenna without attenuation, thus improving the signal-to-noise ratio and error rate. By enhancing the capabilities of radio frequency (RF) systems, MIMO technology can create more stable connections, reduce congestion, and achieve high data throughput.

[0004] In mobile communication systems, diversity gain or multiplexing gain can be achieved if the UE can support a large number of MIMO layers. However, the number of available MIMO layers is limited by the channel quality between the network node (e.g., base station (BS) or next-generation Node-B (gNB)) and the UE. Furthermore, hardware and / or software limitations, as well as power limitations, can also restrict the UE's MIMO capabilities. Therefore, if another device controlled by the UE (e.g., a cooperating UE, relay, or repeater that may be wirelessly connected to the UE as an external antenna panel) can help forward data / signals via another frequency, the effective number of MIMO layers can be significantly increased and MIMO performance improved.

[0005] To support data forwarding, Uu interface data in frequency f1 (or band #1) is forwarded between the primary UE and cooperating UE via frequency f2 (or band #2). However, the data forwarding operations performed by the cooperating UE on the primary UE may increase overall power consumption. Furthermore, not only is the desired signal transmitted, but interference may also be transmitted to network nodes during data forwarding.

[0006] Therefore, optimizing the overall performance of data forwarding operations is an important issue in newly developed wireless communication networks. Summary of the Invention

However, it should be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matter, which can be implemented in various forms. The invention can be implemented in many different forms and should not be construed as limited to the exemplary embodiments and implementations described herein.

In the following description, well-known features and technical details may be omitted to avoid unnecessarily obscuring the embodiments and implementations of the invention.

[0024] Overview

[0025] Implementations of the present invention relate to various techniques, methods, schemes, and / or solutions related to switching control of data forwarding operations of cooperating UEs in mobile communications. According to the present invention, many possible solutions can be implemented individually or in combination. That is, although these possible solutions may be described individually below, two or more of them may be implemented in one or another combination.

[0026] Figure 1An example scenario 100 is illustrated under an implementation according to the present invention. Scenario 100 involves at least one primary UE, one cooperating UE, and one network node, which may be 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 a framework for data forwarding operations in a communication system. The primary UE can extend its MIMO capabilities (e.g., the effective number of MIMO layers) by using data forwarding from the cooperating UE. Specifically, the primary UE can communicate directly with the network node (e.g., a gNB) on a first frequency f1 (or in a first frequency band #1, e.g., in a licensed frequency band). The first frequency f1 may include an intermediate frequency (e.g., frequency range 1 (FR1)) with wide coverage and suitability for long-distance communication. In addition to direct communication with the network node, the primary UE can also establish indirect communication with the network node through the cooperating UE. The cooperating UE can communicate with the primary UE on a second frequency f2 (or in a second frequency band #2, e.g., in an unlicensed frequency band). The second frequency f2 may include a high-frequency frequency (e.g., frequency range 2, FR2) that has a high data rate and is suitable for short-range communication. For long-range communication, the cooperating UE may also communicate with the network node on the first frequency f1 (or the first frequency band #1). Therefore, the cooperating UE can perform cross-band frequency conversion, converting or modulating the first frequency f1 in the first frequency band #1 to the second frequency f2 in the second frequency band #2, or converting or modulating the second frequency f2 in the second frequency band #2 to the first frequency f1 in the first frequency band #1. The cooperating UE can help forward data transmission between the primary UE and the network node. The data forwarding performed by the cooperating UE may include layer 1 (L1) forwarding and / or layer 2 (L2) forwarding. For example, the cooperating UE can perform amplification and forwarding between frequency band #1 and frequency band #2 with almost no delay. Please note that the first and second frequency bands here refer to two non-overlapping frequency resources, and are not limited to two different "frequency bands" specifically defined by organizations such as the International Telecommunication Union (ITU) or the 3rd Generation Partnership Project (3GPP). For example, they could be two non-overlapping component carriers with non-overlapping frequency resources within a frequency band (e.g., band n78) defined by 3GPP for 5G NR.

[0027] However, data forwarding operations performed by the primary UE inevitably lead to power consumption for the cooperating UE. Furthermore, not only are necessary signals (e.g., Uu interface data) transmitted, but unwanted interference may also be transmitted to network nodes during data forwarding. For example, the primary UE may perform a "Listen Before Talk" (LBT) procedure before transmitting in an unlicensed frequency band. This introduces a degree of uncertainty into the link between the primary and cooperating UEs, as the outcome of the LBT procedure is transparent to the cooperating UE. When the primary UE detects that the communication channel is occupied by another device, it avoids transmitting signals or data to the cooperating UE. However, the cooperating UE, unaware of this, still receives signals from other devices, which is considered unwanted interference. Therefore, the cooperating UE may unintentionally transmit this interference to network nodes.

[0028] To mitigate unwanted interference during forwarding, the cooperating UE can dynamically and intelligently switch to a shutdown state when the primary UE is not transmitting a signal, thereby preventing interference during periods when signal forwarding is not required.

[0029] In view of the above, this invention proposes some solutions related to efficient switching control or management of data forwarding operations of cooperating UEs in mobile communications, such as efficient switching control of data forwarding operations performed on unlicensed frequency bands. In some implementations, the cooperating UE can operate in an on or off state. The default operating state of the cooperating UE can be off. When operating in the on state, data forwarding operations are activated, while when operating in the off state, data forwarding operations are deactivated.

[0030] According to the present invention, the data forwarding operation of the cooperating UE can be controlled based on the configuration associated with the primary UE, and the control of the opening or closing state of the data forwarding operation can be performed by the primary UE or the cooperating UE.

[0031] In a first aspect of the invention, the activation and deactivation of data forwarding operations (i.e., on / off control of data forwarding operations) can be determined by the cooperating UE. The cooperating UE can acquire necessary information to predict the timing of uplink transmissions (e.g., signal or data transmissions) that should be forwarded. The cooperating UE can decode control information indicating the timing of uplink transmissions that should be forwarded. The behavior of the cooperating UE, including control of its on / off state, can be adjusted based on the acquired information. For example, data forwarding operations can be dynamically activated or deactivated based on the uplink transmission requirements or uplink transmission timing of the primary UE. Therefore, unwanted interference will not be transmitted to network nodes, and the power consumption of the cooperating UE can also be reduced.

[0032] More specifically, from the perspective of the cooperating UE, the cooperating UE can obtain at least one configuration parameter related to the primary UE. The configuration parameter can indicate (whether implicit or explicit) the primary UE's uplink transmission scheduling or may be related to the primary UE's uplink transmission scheduling. The cooperating UE can receive the configuration parameter from the primary UE or a network node.

[0033] The cooperating UE can determine the timing for activating data forwarding operations based on configuration parameters. During the event where data forwarding operations are activated, the cooperating UE can forward data from the primary UE to the network node, for example, as... Figure 1 The diagram shows the indirect communication between the primary UE and the network node.

[0034] Specifically, in data forwarding operations, the cooperating UE can receive a first RF signal from the primary UE and send a second RF signal to the network node. Both the first and second RF signals can carry the uplink data that the primary UE wants to transmit to the network node. The second RF signal can be transmitted in a first frequency band, while the first RF signal can be received in a second frequency band, and the first frequency band can be different from the second frequency band. In some implementations, the first and second RF signals can carry the same uplink data for transmission to the network node. Therefore, the cooperating UE can help forward the primary UE's uplink data to the network node.

[0035] In some implementations, the configuration parameters may include at least one of the following: configuration parameters for the sounding reference signal (SRS), the physical downlink control channel (PDCCH), and the physical uplink shared channel (PUSCH).

[0036] Through SRS configuration, the cooperating UE can determine the SRS transmission timing of the primary UE. The cooperating UE can know or understand the SRS transmission configuration assigned to the primary UE, such as the time-frequency position within a time slot and the periodicity of SRS transmissions. This information helps the cooperating UE predict when SRS transmissions will occur.

[0037] By using the configuration authorization parameters of the PUSCH, the cooperating UE can determine the data transmission timing of the primary UE on the configuration-authorized PUSCH.

[0038] In some implementations, the cooperating UE can determine the uplink transmission timing of the primary UE based on the SRS transmission timing and / or data transmission timing, and determine the time to activate the data forwarding operation based on the uplink transmission timing.

[0039] In some implementations, through PDCCH configuration, cooperating UEs can derive or determine the time-frequency resources for control information (e.g., downlink control information (DCI) indications) transmitted by network nodes. The timing of data transmission can be indicated by network nodes through control information (e.g., uplink grant DCI), which can provide specific timing details to the primary UE.

[0040] The cooperating UE may further receive at least one decoding parameter associated with the primary UE from the primary UE or a network node. The decoding parameter may include at least one of the following: a radio network temporary identifier (RNTI), a control resource set (CORESET), and a search space associated with the primary UE.

[0041] The cooperating UE can monitor and receive control information (which can be represented as control signals) sent by network nodes for the primary UE based on configuration parameters (e.g., PDCCH settings configured for the primary UE), and decode the control information (i.e., control signals) according to decoding parameters. In some implementations, control signals may include DCI for uplink granting or group-based DCI (i.e., group scheduling based on DCI or group scheduling via DCI). Group-based DCI can indicate the data transmission timing allocated to the primary UE.

[0042] After decoding the control signal, the cooperating UE can determine the uplink transmission timing of the primary UE based on the content of the control signal, and determine the time to activate the data forwarding operation based on the uplink transmission timing.

[0043] Monitoring, receiving, and / or decoding of control signals can be performed in auxiliary mode. The cooperating UE can receive a trigger signal from the primary UE to initiate auxiliary mode and a termination signal from the primary UE to terminate auxiliary mode.

[0044] In some implementations, data forwarding operations can be activated in auxiliary mode. In auxiliary mode, and before activating data forwarding operations or switching from the off state to the on state, the cooperating UE can further perform channel sensing based on duration and power threshold criteria to determine whether the communication channel between the cooperating UE and the primary UE is available.

[0045] In an event where the communication channel is determined to be available, the cooperating UE can determine to activate data forwarding operation or switch to the enabled state. In an event where the communication channel is determined to be unavailable, the cooperating UE can determine not to activate data forwarding operation or remain in the disabled state.

[0046] From the perspective of the primary UE, the primary UE can send at least one configuration parameter associated with the primary UE to the cooperating UE to assist the cooperating UE in determining the time to activate data forwarding operations. The configuration parameter may include at least one of the following: SRS configuration, PDCCH configuration, and PUSCH configuration authorization parameters.

[0047] The primary UE can further transmit a first RF signal to the network node in a first frequency band according to configuration parameters, and transmit a second RF signal to the cooperating UE in a second frequency band different from the first frequency band when the data forwarding operation of the cooperating UE is activated. In some implementations, the first RF signal and the second RF signal can carry uplink data of the primary UE for transmission to the network node, and the uplink data carried in the first RF signal and the second RF signal can be the same.

[0048] The primary UE can further send a trigger signal to the cooperating UE to initiate the auxiliary mode of the cooperating UE, and send a termination signal to the cooperating UE to terminate the auxiliary mode. In auxiliary mode, the cooperating UE can monitor and receive control signals for the primary UE.

[0049] The primary UE can further send decoding parameters to the cooperating UE to assist the cooperating UE in decoding control signals. The decoding parameters may include at least one of the following: RNTI, CORESET, and search space associated with the primary UE, and the control signals may include DCI for uplink authorization or group-based DCI.

[0050] In a second aspect of the invention, the activation and deactivation of data forwarding operations (i.e., the on / off control of data forwarding operations) can be determined by the primary UE. Data forwarding operations can be dynamically activated or deactivated based on the primary UE's uplink transmission requirements or uplink transmission timing. Therefore, unwanted interference will not be transmitted to network nodes, and the power consumption of cooperating UEs can be reduced.

[0051] From the perspective of the primary UE, the primary UE can send an indication to activate the data forwarding operation of the cooperating UE. The indication may include information related to the duration or start and end times of the activated data forwarding operation. In some implementations, this information is determined based on at least one of the following: SRS configuration, PDCCH configuration, PUSCH configuration grant parameters, DCI for uplink grant, group-based DCI for uplink grant, and channel occupancy time (COT) obtained by the primary UE.

[0052] The primary UE can transmit a first RF signal to the network node in a first frequency band, and transmit a second RF signal to the cooperating UE in a second frequency band upon activation of data forwarding operation. Both the first and second RF signals can carry the primary UE's uplink data for transmission to the network node, and the cooperating UE can forward the primary UE's uplink data to the network node. In some implementations, the first and second RF signals can carry the same uplink data for transmission to the network node, and the first frequency band can be different from the second frequency band.

[0053] In some implementations, the primary UE can perform channel sensing to determine whether a communication channel between the primary UE and the cooperating UE is available. For example, the primary UE can perform channel sensing (e.g., by performing an LBT procedure) before the start of the next transmission in band #2 (e.g., PUSCH, Physical Uplink Control Channel (PUCCH), or SRS transmission), and can obtain a COT when the communication channel is determined to be available during the LBT procedure. An indication can be sent to the cooperating UE upon the event that the communication channel is determined to be available. In some implementations, upon the event that the communication channel is determined to be available, the primary UE can further transmit dummy data in the second band before transmitting a second RF signal and after obtaining the COT or after transmitting the indication.

[0054] Figure 2 An example scenario 200 of an implementation according to the first aspect of the present invention is illustrated. The cooperative UE can operate in non-assisted mode by default. Furthermore, the cooperative UE can operate in a closed state (by...). Figure 2 The black arrow extending vertically in the middle indicates that data forwarding is not activated by default.

[0055] The primary UE can communicate with the collaborating UE via wireless communication protocols, such as Wi-Fi or Bluetooth. The primary or collaborating UE can perform device discovery and association procedures to enable communication between them.

[0056] After communication is established between the primary UE and the cooperating UE, the primary UE can receive at least one configuration parameter from the network node and send the configuration parameter to the cooperating UE. The configuration parameter may include at least one of the configuration authorization parameters of SRS configuration, PDCCH configuration, and PUSCH.

[0057] In some implementations, the cooperating UE can also receive configuration parameters directly from the network node. Through these configuration parameters, the cooperating UE can obtain the uplink transmission time of the primary UE.

[0058] In some implementations, the cooperating UE can further receive data from the primary UE or network node (not in...). Figure 2 (As shown in the image) Receives at least one decoding parameter associated with the primary UE. The decoding parameter may include at least one of RNTI, CORESET, and search space associated with the primary UE. The decoding parameter can be used to decode control information transmitted to the primary UE by the network node, and the cooperating UE can also obtain the uplink transmission time of the primary UE based on the decoding result.

[0059] The primary UE can send SRS to the cooperating UE in band #2, and in the event that data forwarding operation is activated, it can forward the SRS to the network node in band #1. In scenario 200, since the cooperating UE has not yet switched to the enabled state, the SRS is not forwarded in band #1.

[0060] In response to traffic arrival, the primary UE can send a scheduling request to the network node when there are no available uplink resources, and can also send a trigger signal to the cooperating UE to trigger or initiate auxiliary mode.

[0061] The cooperating UE can operate in auxiliary mode in response to a trigger signal. In auxiliary mode, the cooperating UE can monitor the control information (e.g., uplink grant (DCI)) transmitted by network nodes to the primary UE according to configuration parameters (e.g., PDCCH configuration), and decode the uplink grant according to decoding parameters. Through the control information (e.g., uplink grant information), the cooperating UE can obtain the data transmission time of the primary UE.

[0062] Based on the information obtained about the primary UE's data transmission time, the cooperating UE can perform channel sensing for a duration prior to any transmission time of the primary UE. For example, the cooperating UE can perform channel sensing before switching to the on state (i.e., activating data forwarding operation).

[0063] The cooperating UE can perform channel sensing based on duration (e.g., sensing duration) and power threshold criteria to determine whether the communication channel between the cooperating UE and the primary UE is available. Sensing may fail if the sensed power level is higher than the power threshold. The cooperating UE may assume the measured channel is busy and that the primary UE is unlikely to transmit one or more signals on that channel. Therefore, the communication channel may be determined to be unavailable. In the event that the communication channel is determined to be unavailable, the cooperating UE may decide not to activate data forwarding operations and remain in a disabled state.

[0064] On the other hand, sensing may pass when the sensed power level is not higher than a power threshold. The cooperating UE may assume that the measured channel is not busy, and that the primary UE may be transmitting one or more signals on that channel. Therefore, the communication channel may be determined to be available. In the event that the communication channel is determined to be available, the cooperating UE may determine to switch to the on state (by...). Figure 2(Indicated by the white arrow extending vertically in the middle) and activate the data forwarding operation.

[0065] The primary UE can transmit data to the network node in frequency band #1 at the data transmission time indicated or configured by the network node, and can also transmit data to the cooperating UE in frequency band #2. The cooperating UE can perform inter-band frequency conversion to convert or modulate the data signal from frequency band #2 to frequency band #1, and transmit the data to the network node in frequency band #1. In this way, uplink signals or data received by the cooperating UE from the primary UE in frequency band #2 are forwarded to the network node in frequency band #1.

[0066] The cooperating UE can determine to switch to the off state and disable the data forwarding operation when the data forwarding operation is completed.

[0067] In addition, when it is determined that the service buffer is empty, the primary UE can send a termination signal to the cooperating UE to terminate the auxiliary mode.

[0068] Figure 3 Another example scenario 300 of an implementation according to the first aspect of the present invention is shown. The cooperative UE can operate in non-assisted mode by default. Furthermore, the cooperative UE can operate in a closed state (by...). Figure 3 The black arrow extending vertically in the middle indicates that data forwarding is not activated by default.

[0069] The primary UE can communicate with the collaborating UE via wireless communication protocols such as Wi-Fi or Bluetooth. Either the primary or collaborating UE can perform a device discovery and association process to enable communication between them.

[0070] After communication is established between the primary UE and the cooperating UE, the primary UE can receive at least one configuration parameter from the network node and send the configuration parameter to the cooperating UE. The configuration parameter may include at least one of the configuration authorization parameters of SRS configuration, PDCCH configuration, and PUSCH.

[0071] In some implementations, the cooperating UE can also receive configuration parameters directly from the network node. Through these configuration parameters, the cooperating UE can obtain the uplink transmission time of the primary UE.

[0072] Collaborating UEs can be generated from either the primary UE or a network node ( Figure 3 (Not shown) Receives at least one decoding parameter associated with the primary UE. This decoding parameter may include at least one of the following: RNTI, CORESET, and search space associated with the primary UE. This decoding parameter can be used to decode control information transmitted from the network node to the primary UE, and the cooperating UE can also obtain the primary UE's uplink transmission time based on the decoding result.

[0073] In response to service arrival, when no uplink resources are available, the primary UE can send a scheduling request to the network node and can also send a trigger signal to the cooperating UE to trigger or start the auxiliary mode.

[0074] The cooperating UE can perform channel sensing based on duration (e.g., sensing duration) and a power threshold criterion to determine whether the communication channel between the cooperating UE and the primary UE is available. Sensing may fail if the sensed power level is higher than the power threshold. The cooperating UE may perceive the measured channel as busy, and the primary UE may not transmit one or more signals through that channel. Therefore, the communication channel may be determined to be unavailable. In the event that the communication channel is determined to be unavailable, the cooperating UE can determine not to activate data forwarding operations and remain in a disabled state.

[0075] On the other hand, sensing may pass if the sensed power level is not higher than a power threshold. The cooperating UE may assume the measured channel is not busy, and the primary UE may transmit one or more signals through that channel. Therefore, the communication channel may be determined to be available. In the event that the communication channel is determined to be available, the cooperating UE can determine to switch to an on state (e.g., Figure 3 (As shown by the white arrow extending vertically in the middle) and activate the data forwarding operation.

[0076] The primary UE can send SRS to the cooperating UE in band #2 according to the SRS configuration, and forward the SRS to the network node in band #1 when the data forwarding operation is activated. The cooperating UE can perform inter-band frequency conversion, switching or tuning the SRS from band #2 to band #1, and send the SRS to the network node in band #1. In this way, the SRS received by the cooperating UE from the primary UE in band #2 is forwarded to the network node in band #1.

[0077] When the SRS data forwarding operation is completed, the cooperating UE can determine to switch to the off state and disable the data forwarding operation.

[0078] In auxiliary mode, the cooperating UE can continuously monitor the control information (e.g., uplink grant (DCI)) transmitted by network nodes to the primary UE based on configuration parameters (e.g., PDCCH configuration), and decode the uplink grant according to decoding parameters. Through the control information (e.g., uplink grant information), the cooperating UE can obtain the data transmission time of the primary UE.

[0079] Before switching back to the ON state, the cooperating UE can perform channel sensing based on duration (e.g., sensing duration) and power threshold criteria to determine whether a communication channel between the cooperating UE and the primary UE is available. Upon determining that the communication channel is available, the cooperating UE can decide to switch to the ON state and activate data forwarding operations.

[0080] The primary UE can transmit data to the network node in frequency band #1 at the data transmission time indicated or configured by the network node, and can also transmit data to the cooperating UE in frequency band #2. The cooperating UE can perform inter-band frequency conversion, converting or modulating the data signal from frequency band #2 to frequency band #1, and then transmit the data to the network node in frequency band #1. In this way, uplink signals or data received by the cooperating UE from the primary UE in frequency band #2 are forwarded to the network node in frequency band #1.

[0081] When the data forwarding operation is complete, the cooperating UE can determine to switch to the off state and disable the data forwarding operation.

[0082] In addition, when it is determined that the service buffer is empty, the primary UE can send a termination signal to the cooperating UE to terminate the auxiliary mode.

[0083] Figure 4 Another example scenario 400 of an implementation according to the second aspect of the present invention is illustrated. The cooperative UE can operate in a closed state (e.g., Figure 4 (As shown by the black arrow extending vertically in the middle), where data forwarding is not activated by default.

[0084] The primary UE can communicate with the collaborating UE via wireless communication protocols (e.g., Wi-Fi or Bluetooth). The primary or collaborating UE can perform device discovery and association procedures to enable communication between them.

[0085] The primary UE can perform channel sensing (e.g., by performing an LBT procedure) before the next transmission in band #2 (e.g., PUSCH, PUCCH, or SRS transmission) begins. When the communication channel is determined to be available, the primary UE can obtain COT.

[0086] The primary UE can determine the duration or start and end times of the data forwarding operation to activate the cooperating UE, and send an indication to the cooperating UE to activate the data forwarding operation after the primary UE obtains the COT. In some implementations, this indication may include information related to the duration or start and end times of activating the data forwarding operation (e.g., such as...). Figure 4 (The control information shown).

[0087] In some implementations, the start time can be the next transmission time, and the duration can be the COT duration obtained by the primary UE. In some implementations, control information can be determined based on at least one of SRS configuration, PDCCH configuration, PUSCH configuration authorization parameters, DCI for uplink authorization, and group-based DCI for uplink authorization. Control information can be provided selectively in events where control information has already been provided and the duration has not changed.

[0088] In some implementations, upon determining that a communication channel is available, the primary UE can transmit virtual data in the second band #2 before transmitting signals or data to be forwarded to the cooperating UE. The primary UE can transmit virtual data until uplink (e.g., SRS or PUSCH) transmission arrives.

[0089] The cooperating UE can actively maintain its enabled state from the start time and can remain operational throughout the entire duration. While operating in the enabled state, the cooperating UE can receive SRS from the primary UE in band #2 and forward the SRS to the network node in band #1. The cooperating UE can perform inter-band frequency conversion, switching or tuning the SRS from band #2 to band #1, and then sending the SRS to the network node in band #1.

[0090] Furthermore, the primary UE can transmit data to the network node in frequency band #1 within the data transmission time indicated or configured by the network node, and can also transmit data to the cooperating UE in frequency band #2. The cooperating UE can perform frequency conversion between frequency bands, converting or modulating the data signal from frequency band #2 to frequency band #1, and then transmit the data to the network node in frequency band #1. In this way, uplink signals or data received by the cooperating UE from the primary UE in frequency band #2 are forwarded to the network node in frequency band #1.

[0091] The cooperating UE can determine when to switch to the off state and disable data forwarding operations when the end time or duration indicated by the primary UE expires.

[0092] In summary, the proposed scheme, which involves effective switching control or management of data forwarding operations of cooperating UEs in mobile communications, prevents unwanted interference from being transmitted to network nodes and reduces the power consumption of cooperating UEs.

It should be understood that the architectures described in this way are merely exemplary, and other architectures capable of achieving the same functionality can actually be implemented. Conceptually, the arrangement of any components that achieve the same function is effectively “associated” to achieve the desired function. Therefore, regardless of the architecture or intermediate components, any two components combined herein to achieve a particular function can be considered “associated” with each other to achieve the desired function. Similarly, any two such associated components can also be considered “operably connected” or “operably coupled” to each other to achieve the desired function, and any two components that can be suchly associated can also be considered “operably coupled” to each other to achieve the desired function. Specific examples of operability and coupling include, but are not limited to, physically matchable and / or physically interactive components and / or wirelessly interactive and / or logically interactive components.

Furthermore, even when the specific number of claims to which are introduced is explicitly stated, those skilled in the art should recognize that such statements should be interpreted as indicating at least the number stated (e.g., the statement "two statements" without other modifiers means at least two statements or two or more statements). Additionally, in instances where the customary usage of phrases like "at least one of A, B, and C" is used, such a construction is generally intended to express the meaning of the customary usage as understood by those skilled in the art; for example, "a system having at least one of A, B, and C" will include, but is not limited to, systems having only A, only B, only C, A and B, A and C, B and C, and / or systems having A, B, and C, etc. In instances where the customary usage of phrases like "at least one of A, B, or C" is used, such a construction is generally intended to express the meaning of the customary usage as understood by those skilled in the art; for example, "a system having at least one of A, B, or C" will include, but is not limited to, systems having only A, only B, only C, A and B, A and C, B and C, and / or systems having A, B, and C, etc. Those skilled in the art will also understand that virtually any transition words and / or phrases presenting two or more options, whether in the specification, claims, or drawings, should be understood to include the possibility of one, either, or both.
