Description

Technical Field

[0001] Technical Field The present disclosure generally relates to wireless communications including, but not limited to, systems and methods for simultaneous backhaul link and control link transmission for network nodes.

Background Art

[0002] Background Coverage is a fundamental aspect of cellular network deployment. Mobile operators rely on different types of network nodes to provide blanket coverage in their deployments. As a result, new types of network nodes are thought to enhance the flexibility of mobile operators in network deployment. For example, a particular system or architecture may introduce integrated access and backhaul (IAB), a new type of network node that does not require a wired backhaul and can be enhanced in certain other systems. Another type of network node is an RF repeater that simply amplifies and forwards any signal it receives. RF repeaters are envisioned for a wide range of deployments in 2G, 3G, and 4G to supplement the coverage provided by normal full-stack cells.

[0017] The systems and methods presented herein include novel techniques for simultaneous backhaul link and control link (C-link) transmission for network nodes. Specifically, the systems and methods presented herein discuss novel solutions for prioritizing one of the C-link or backhaul link transmissions to avoid the total power of simultaneous C-link and backhaul link transmissions exceeding a maximum power constraint / threshold / cap (e.g., maximum power threshold). In some exemplary embodiments, if the sum of the control link (C-link) power and the backhaul link power exceeds the total maximum power constraint, one of the links is dropped according to or in accordance with at least one predetermined rule. If a C-link is dropped according to at least one predetermined rule, a smart node (SN) communication unit (CU) (e.g., a network control repeater (NCR) mobile terminal (MT)) can retransmit the dropped signal on the same frequency domain resources.

In some exemplary configurations, the C link and the backhaul link can share the total maximum power constraint and the output power of the backhaul link can be prioritized. In some exemplary configurations, a wireless communication node (e.g., gNB, BS, or TRP) can transmit a power control indication to the NCR to adjust the output power of the backhaul link, for example, to ensure that the sum of the powers of the C link and the backhaul link does not exceed the total maximum power constraint. The power control indication is ● Transmission power: ○ When the transmission power is indicated, the amplification gain can be calculated as amplification gain = transmission power / input power. ○ The sum of the transmission powers of the backhaul link and the C link can be less than the maximum total power. ● Amplification gain: ○ When the amplification gain is indicated, the transmission power can be determined / calculated as transmission power = min(maximum total power - C link power, input power × amplification gain). ● Frequency resource. ● Time resource.

Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating within its allocated bandwidth to provide adequate radio coverage to its target users.

[0027] For example, BS102 may operate within the channel transmission bandwidth allocated to provide adequate coverage to UE104. BS102 and UE104 may communicate via downlink radio frames 118 and uplink radio frames 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may contain data symbols 122 / 128. In this disclosure, BS102 and UE104 are described herein as non-limiting examples of “communication nodes” that can generally implement the methods disclosed herein. Such communication nodes may be capable of performing wireless and / or wired communications according to various embodiments of the present solution.

[0028] Figure 2 shows a block diagram of an exemplary wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) according to several embodiments of the present solution. The system 200 may include components and elements configured to support known or conventional operating features not necessarily described in detail herein. In one exemplary embodiment, the system 200 can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 in Figure 1, as described above.

[0029] System 200 generally includes a base station 202 (hereinafter, "BS202") and a user equipment device 204 (hereinafter, "UE204").

[0030] As will be understood by those skilled in the art, System 200 may further include any number of modules other than those shown in Figure 2. Those skilled in the art will understand that various exemplary blocks, modules, circuits, and processing logic described in relation to the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this compatibility and suitability of hardware, firmware, and software, various exemplary components, blocks, modules, circuits, and steps are generally described in relation to their functionality. Whether such functionality is implemented as hardware, firmware, or software may depend on the specific application and the design constraints imposed on the system as a whole. Those familiar with the concepts described herein may implement such functionality in a manner suitable for a specific application, but such a decision on implementation should not be construed as limiting the scope of this disclosure.

Similarly, according to several embodiments, the BS transceiver 210 may be referred herein to as a "downlink" transceiver 210, comprising an RF transmitter and an RF receiver, each having a circuit that is coupled to an antenna 212. Alternatively, a downlink duplex switch may couple the downlink transmitter or receiver to the downlink antenna 212 in a time-duplex manner. The operation of the two transceiver modules 210 and 230 may be time-coordinated so that the downlink transmitter is coupled to the downlink antenna 212 and at the same time the uplink receiver circuit is coupled to the uplink antenna 232 for receiving transmissions over the wireless transmission link 250. Conversely, the operation of the two transceivers 210 and 230 can be time-coordinated so that the uplink transmitter is coupled to the uplink antenna 232 at the same time that the downlink receiver is coupled to the downlink antenna 212 for receiving transmissions over the wireless transmission link 250. In some embodiments, there is strict time synchronization with a minimum guard time between changes in duplex direction.

[0032] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via a wireless data communication link 250 and to cooperate with a appropriately configured RF antenna array 212 / 232 capable of supporting specific wireless communication protocols and modulation schemes.

[0036] The Open System Interconnection (OSI) model (hereinafter referred to as the “Open System Interconnection Model”) is a conceptual and logical layout that defines network communications used by systems (e.g., wireless communication devices, wireless communication nodes) that are open to interconnection and communication with other systems.

[0038] 2. System and method for simultaneous backhaul link and control link transmission for network nodes In certain systems (e.g., 5G New Radio (NR), Next Generation (NG) systems, 3GPP® systems, and / or other systems), different types of network nodes can be used to enhance coverage in cellular network configurations (e.g., providing blanket coverage). New types of network nodes may be introduced or considered to increase the flexibility of network deployment. For example, IAB can be deployed as a new type of network node that does not require wired backhaul. Another type of network node may be an RF repeater. RF repeaters can be deployed or configured to receive, amplify, and forward any signal. RF repeaters can be deployed in various network environments, for example, to complement the coverage provided by a typical full-stack cell.

[0039] As an extension beyond conventional RF repeaters, network-controlled repeaters (NCRs) with the capacity to receive and / or process side control information from the network may be introduced. Side control information can enable the network-controlled repeater to perform / operate its amplified forwarding operation in a more efficient manner. Specific advantages may include, at a minimum, reduced unwanted noise amplification, transmission and reception with better spatial directivity, and / or simplified network integration.

[0040] NCR can be considered a stepping stone (e.g., a modified, alternative, or altered form) of a Reconfigurable Intelligent Surface (RIS). RIS nodes can adjust the phase and amplitude of received signals to improve / enhance coverage (e.g., network communication coverage). Network nodes, including but not limited to network control repeaters, smart repeaters, extended RF repeaters, Reconfigurable Intelligent Surfaces (RISs), and / or Integrated Access and Backhaul (IABs), as described herein, may, for simplicity, be referred to, referenced, or provided as smart nodes (SNs) (e.g., network nodes). For example, an SN may include, correspond to, or refer to certain network nodes to help BS102 improve coverage (e.g., avoiding / preventing interference / blockages, increasing transmission range, etc.). In a particular system, an SN may initiate / implement control link (C-link) transmission and backhaul link transmission simultaneously (e.g., relatively simultaneously). Simultaneous transmission over C-link and backhaul links may consume a certain amount of power exceeding the maximum power threshold. Therefore, the systems and methods of this technical solution can implement the features, operations, techniques, and / or methods described herein to prioritize either a C-link or a backhaul link in order to avoid exceeding the total power of simultaneous C-link and backhaul link transmissions. As described herein, the systems and methods can prioritize a C-link or a backhaul link by dropping one of the transmissions or by configuring / adjusting the power of the C-link transmission and / or backhaul link transmission.

[0041] Figure 3 shows a schematic diagram of an exemplary network 300. As shown in Figure 3, if there is interference between BS102 and UE104, one or more BS102A-B (e.g., BS102) can serve one or more UE104A-B (e.g., UE104) in their respective cells via one or more SN306A-B (e.g., sometimes labeled as SN(plural)306).

[0042] Figure 4 shows a schematic diagram of the transmission links from BS102 to SN306 and from SN306 to UE104. SN306 (e.g., a network node) may include, or be composed of, at least two units or functional components / components (e.g., sometimes referred to as functional entities), such as a communication unit (CU) (e.g., SN CU) and a forwarding unit (FU) (e.g., SN FU). Each unit of SN306 may support a different function for communication with at least one of BS102 and / or UE104. In some cases, the first unit (or functional entity) of SN306 may refer to an SN CU, and the second unit (or functional entity) of SN306 may refer to an SN FU, or vice versa. For example, the SN CU (e.g., the first unit) may be a network control repeater (NCR) mobile terminal (MT). In another example, the SN FU (e.g., a second unit) could be an NCR forwarder / transfer (Fwd). The SN CU could act / behave similarly to the UE104, for example, to receive and decode side control information from BS102. The SN CU could be a control unit, controller, MT, part of the UE, a third-party IoT device, etc. The SN FU could perform intelligent amplified forwarding operations using the side control information received by the SN CU. The SN FU could be a radio unit (RU), RIS, etc.

[0043] The transmission links from BS102 to SN306 and from SN306 to UE104, as shown in Figure 4, can be defined / described / provided as follows. C1: SN Control link (C-link) from CU to BS. C2: Control link (C-link) from BS to SN CU F1: SN Transfer link from FU to BS (backhaul link) F2: Transfer link from BS to SN FU (backhaul link), F3: Transfer link (access link) from UE to SN FU, and F4:SN Transfer link (access link) from FU to UE.

[0044] A control link (which may be referred to as, for example, a communication link) refers to, or may mean, a link in which signals from one side are detected and decoded by the other side, and as a result, information transmitted over the control link can be used to control the status of the transport links (e.g., backhaul links and / or access links, F-links). In some embodiments, the control link may correspond to or be referred to as a communication link.

[0045] A forwarding link can mean that the signal from BS102 or UE104 is unknown to the SN FU (e.g., undecoded or unchecked). In this case, the SN FU can amplify and forward the signal without decoding it. For example, links F1 and F3 may correspond to or be associated with full uplink (UL) forwarding links from UE104 to BS102 (e.g., backhaul link and access link, respectively), with F1 being the SN FU UL forwarding link. Additionally, links F2 and F4 may correspond to or be associated with full DL forwarding links from BS102 to UE104 (e.g., backhaul link and access link, respectively), with F4 being the SN FU DL forwarding link. Links F1 and F2 may correspond to or be referred to as backhaul links, and links F3 and F4 may correspond to or be referred to as access links.

[0046] Referring to Figure 5, examples of implementation structures 500 for simultaneous backhaul link and control link transmissions are shown according to several embodiments of the present disclosure. For simultaneous backhaul link and C-link transmissions (e.g., F1 and C1, respectively), the total power of the two transmissions (e.g., the sum of C-link power and backhaul link power) is expected to be less than or equal to (e.g., not exceed) the total maximum power constraint / limit / cap (e.g., maximum power threshold). To avoid the total power of the two transmissions exceeding the total maximum power constraint, the following exemplary features can be considered.

[0047] In some configurations, signals / channels within the backhaul link (e.g., F1) can be transparent to the SN306, allowing, for example, the SN FU (or NCR Fwd) to transfer signals from UE104 to BS102 without knowing the content of the signals. In some configurations, the total maximum power may be a fixed value. In some other configurations, the total maximum power can be adjusted according to or based on the capacity of the SN306.

[0048] In various embodiments of this disclosure, unless expressly indicated / referenced / presented (e.g., in exemplary embodiment 3), the power of the C-link may be determined / calculated / calculated based on the UE power control mechanism of a particular system for different channels, among other types of channels, such as physical uplink control channel (PUCCH) transmission, physical uplink shared channel (PUSCH) transmission, physical random access channel (PRACH), and / or sounding reference signal (SRS). In some embodiments, the C-link power calculation formula may be presented / described / indicated as follows: ● When a C-link transmits a push signal, the C-link power can be calculated as follows: [ka] ● When a C-link transmits PUCCH, the C-link power can be calculated as follows: [ka] ● When a C-link transmits PRACH, the C-link power can be calculated as follows: [ka] ● When a C-link transmits SRS, the C-link power can be calculated as follows: [ka]

[0049] Exemplary Embodiment 0: Separate / different maximum power constraints (or thresholds) configured for backhaul links and C-links In some embodiments, the backhaul link and the C-link may be configured with separate maximum power constraints. In this case, if the C-link and the backhaul link are transmitted / transmitted / forwarded simultaneously (e.g., signals configured to be transmitted simultaneously through the C-link and the backhaul link), the power of the C-link or the power associated with the C-link may be lower than the first maximum power constraint, and / or the power of the backhaul link may be lower than the second maximum power constraint. The first maximum power constraint may be different from the second maximum power constraint. In some embodiments, both the first maximum power constraint / threshold and the second maximum power constraint may be configured by BS102. In some embodiments, at least one of the first maximum power constraint and / or the second maximum power constraint may be calculated / determined by / based on / and thus determined by / the total maximum power constraint minus the other of the first and second maximum power constraints.

[0050] The C-link power can be determined / calculated according to a formula for different signals / channels (e.g., determined C-link power). Therefore, the actual C-link power can be the minimum of either the first maximum power constraint or the determined C-link power (e.g., min(first maximum power constraint, determined C-link power)).

[0051] The backhaul link power can be determined / calculated as the minimum of either the second maximum power constraint or the product of the input power and the (configured) amplification gain (e.g., min(second maximum power constraint, input power × amplification gain)). In some embodiments, the configured amplification gain can be applied to different scenarios such as simultaneous C-link and backhaul link transmission, and time-division multiplexed C-link and backhaul link transmission. In some embodiments, the sum of the first and second maximum power constraints may be less than or equal to (e.g., less than or equal to) the total maximum power constraint (e.g., third maximum power constraint), thereby avoiding a total maximum power between C-link and backhaul link transmissions that exceeds the total maximum power constraint. In some embodiments, the first maximum power constraint may not be related to the second maximum power constraint. For example, the SN CU (e.g., NCR MT) and SN FU (e.g., NCR Fwd) may have separate radio frequency (RF) components. In various embodiments, the signal associated with the C-link may be referred to as the first signal, the power associated with the C-link transmission may be referred to as the first power, the signal associated with the backhaul link may be referred to as the second signal, and the power associated with the backhaul link may be referred to as the second power.

[0052] Embodiment 1: The sum of the C-link and backhaul link power exceeds the total maximum power constraint. In some embodiments, in response to the SN306 (e.g., a network node) calculating the total power consumed by simultaneous C-link and backhaul link transmissions (e.g., the sum of C-link power and backhaul link power), the SN306 can determine whether the total power exceeds the total maximum power constraint. If the total power exceeds the total maximum power constraint, the SN306 can drop / cancel / terminate / skip / bypass one of the links' transmissions (e.g., perform the transmission on one of the links) according to the following predefined / predetermined / configured rules (e.g., sometimes referred to as prioritization rules).

[0053] The prioritization rules may include / be comprise at least one of the following: ● Regardless of which signal / channel is being transmitted, if the total power exceeds the total maximum power constraint, the C link may be dropped, while the backhaul link may be maintained (for example, transmission may be possible via the backhaul link). ○ In this case, the backhaul link may take precedence over the C-link. C-link transmission may not affect backhaul link transmission. ● If the total power exceeds the total maximum power constraint, the backhaul link can be dropped, and the C link can be maintained regardless of which signal / channel is being transmitted. ○ In this case, the C-link may take precedence over the backhaul link. C-link transmission may not be affected by backhaul link transmission. ● C-link {PRACH transmission, PUCCH transmission} > Backhaul link > Other channels / signals of the C-link. ○ In this case, the priority of the C-link may depend on the specific / exact transmission signal of the C-link, and a link with a lower priority (e.g., either the C-link or the backhaul link) may be dropped. For example, if the C-link is transmitting PRACH and / or PUCCH, the backhaul link may be dropped. In a further example, if the C-link is transmitting other signals (e.g., PUSCH and / or SRS), the C-link may be dropped. ● C-link {PRACH transmission, PUCCH transmission with HARQ-ACK information} > Backhaul link > Other channels / signals of the C-link. ○ In this case, the priority of the C-link may depend on the specific / exact transmission signal of the C-link, and a link with a lower priority (e.g., either the C-link or the backhaul link) may be dropped. For example, if the C-link transmits a PUCCH with PRACH and / or HARQ-ACK information, the backhaul link may be dropped. In a further example, if the C-link transmits other signals (e.g., PUSCH and / or SRS), the C-link may be dropped. ● C-link {PRACH transmission, PUCCH transmission with HARQ-ACK information, PUSCH transmission with HARQ-ACK information} > Backhaul link > Other channels / signals of the C-link. ○ In this case, the priority of the C-link may depend on the specific / exact transmission signal of the C-link, and a link with a lower priority (e.g., either the C-link or the backhaul link) may be dropped. For example, if the C-link transmits PRACH, PUCCH with HARQ-ACK information, and / or PUSCH with HARQ-ACK information, the backhaul link may be dropped. In a further example, if the C-link transmits other signals (e.g., PUSCH and / or SRS with other information), the C-link may be dropped. ● C-link {PUCCH transmission with HARQ-ACK information} > Backhaul link > Other channels / signals on the C-link. ○ In this case, the priority of the C-link may depend on the specific / exact transmission signal of the C-link, and links with lower priority (e.g., either the C-link or the backhaul link) may be dropped. For example, if the C-link transmits a PUCCH with HARQ-ACK information, the backhaul link may be dropped. In a further example, if the C-link transmits other signals (e.g., PUSCH and / or SRS), the C-link may be dropped. ● C-link {PUCCH transmission with HARQ-ACK information, PUSCH transmission with HARQ-ACK information} > backhaul link > other channels / signals of the C-link. ○ In this case, the priority of the C-link may depend on the specific / exact transmission signal of the C-link, and links with lower priority (e.g., either the C-link or the backhaul link) may be dropped. For example, if the C-link transmits PUCCH with HARQ-ACK information and / or PUSCH with HARQ-ACK information, the backhaul link may be dropped. In a further example, if the C-link transmits other signals (e.g., PUSCH and / or SRS with other information), the C-link may be dropped. ● C-link {PUCCH transmission with HARQ-ACK information, SRS} > backhaul link > other channels / signals on the C-link. ○ In this case, the priority of the C-link may depend on the specific / exact transmission signal of the C-link, and links with lower priority (e.g., either the C-link or the backhaul link) may be dropped. For example, if the C-link transmits PUCCH and / or SRS with HARQ-ACK information, the backhaul link may be dropped. In a further example, if the C-link transmits other signals (e.g., PRACH, PUCCH with other information, PUSCH, etc.), the C-link may be dropped. ● C-link {PRACH, PUCCH transmission with HARQ-ACK information, SRS} > Backhaul link > Other channels / signals on the C-link. ○ In this case, the priority of the C-link may depend on the specific / exact transmission signal of the C-link, and a link with a lower priority (e.g., either the C-link or the backhaul link) may be dropped. For example, if the C-link transmits PRACH, PUCCH and / or SRS with HARQ-ACK information, the backhaul link may be dropped. In a further example, if the C-link transmits other signals (e.g., PUCCH and / or PUSCH with other information), the C-link may be dropped. ● C-link {PRACH, PUCCH transmission with status report} > backhaul link > other channels / signals on the C-link. ○ In this case, the priority of the C-link may depend on the specific / exact transmission signal of the C-link, and a link with a lower priority (e.g., either the C-link or the backhaul link) may be dropped. For example, if the C-link transmits PUCCH with PRACH and / or status reports, the backhaul link may be dropped. In a further example, if the C-link transmits other signals (e.g., PUCCH, SRS, and / or PUSCH with other information), the C-link may be dropped. ○ In this case, the status report may include at least one of the following: abnormal information (e.g., overheating, self-excitation detection, beam interference, radio interference, etc.), measurement reports, and / or HARQ-ACK information. ● C-link {PRACH, PUCCH transmission with status report; PUSCH transmission with status report} > Backhaul link > Other channels / signals of the C-link. ○ In this case, the priority of the C-link may depend on the specific / exact transmission signal of the C-link, and a link with a lower priority (e.g., either the C-link or the backhaul link) may be dropped. For example, if the C-link transmits PRACH, PUCCH with status report, and / or PUSCH with status report, the backhaul link may be dropped. In a further example, if the C-link transmits other signals (e.g., PUCCH with other information, SRS, and / or PUSCH with other information), the C-link may be dropped. ○ In this case, the status report may include at least one of the following: abnormal information (e.g., overheating, self-excitation detection, beam interference, radio interference, etc.), measurement reports, and / or HARQ-ACK information.

[0054] Embodiment 1a: C-links dropped according to predefined rules In some embodiments, SN306 may decide whether to drop a C-link or a backhaul link according to or based on predefined rules (e.g., according to or referencing Exemplary Embodiment 1). If SN306 drops a C-link (e.g., the dropped C-link signal or the first signal) according to predefined rules, the SN CU (or NCR-MT) may retransmit the signal (e.g., the dropped signal) in the same frequency domain resources that were previously allocated to the C-link signal that was not transmitted (e.g., the initial C-link transmission signal and the C-link retransmission signal may be in / on the same frequency domain resources).

[0055] In some cases, if the dropped signal is PRACH, at least one of the following can be performed on the dropped signal: ○ The PRACH signal may be transmitted / transmitted / communicated / signaled in the following Random Access Channel (RACH) opportunity (RO). ○ The PRACH signal will / may be transmitted in the next PRACH slot. ○ The SN CU can re-evaluate the synchronous signal block (SSB) (e.g., perform a DL synchronization procedure) and transmit the PRACH at a time-domain location determined according to the relationship between the selected SSB and PRACH (e.g., follow a RACH procedure).

[0056] In some other cases, if the dropped signal is PUCCH, PUSCH, or SRS, at least one of the following can be done with respect to the dropped signal: ○ A signal (for example, the first signal) can be transmitted / retransmitted in the next slot. ○ The signal can be transmitted through the following uplink (UL) slots. ○ The signal can be transmitted in the time-domain resource according to the indication from BS102. ○ The signal can be transmitted after a predefined / predetermined duration (e.g., 1 ms, 1 slot, 1 frame, etc.) (for example, the time the signal was previously dropped).

[0057] Exemplary Embodiment 2: C-link and backhaul link sharing a total maximum power constraint and prioritizing C-link output power. In various embodiments, the C-link and backhaul link may share a total maximum power constraint (for example, the total maximum power constraint may apply to the sum of the C-link power and the backhaul link power). In some configurations, the SN306 (e.g., a network node) may decide to prioritize the output power of the C-link (e.g., prioritize transmitting the first signal). The output power of the C-link may be determined / calculated for different signals / channels according to at least one of equations (1) to (4). By prioritizing the C-link, the SN306 can reduce the output power of the backhaul link (e.g., the second power) for simultaneous transmission. Thus, the output power of the C-link may not be affected by the backhaul link power (e.g., the output power of the C-link may be prioritized over the output power of the backhaul link).

[0058] The output power of the backhaul link can be determined / calculated / calculated as follows: ● Backhaul link output power = min(maximum total power - C-link power, input power × amplification gain) (for example, the smaller of the value obtained by subtracting the C-link power from the maximum total power, and / or the product of the input power and amplification gain).

[0059] The input power can refer to the incoming signal power from UE104 (e.g., F3 signal power) to SN306. SN306 can reduce the backhaul link power according to the determined output power of the backhaul link. In some cases, SN306 can be adjusted to meet the following constraints / criteria / parameters, which may differ from the actual amplification gain of SN306 (e.g., different from the configured gain value). ● Input power × Actual gain <= Maximum total power - C-link power (for example, the input power multiplied by the actual gain may be less than or equal to the value obtained by subtracting the first power from the maximum total power).

[0060] Exemplary Embodiment 3: C-link and backhaul link sharing a total maximum power constraint and prioritizing the output power of the backhaul link. In various embodiments, the C-link and backhaul link may share a total maximum power constraint (for example, the total maximum power constraint may apply to the sum of the C-link power and the backhaul link power). In some configurations, the SN306 (e.g., a network node) may decide to prioritize the output power of the backhaul link (e.g., to prioritize transmitting a second signal). By prioritizing the backhaul link, the SN306 can determine / calculate the output power of the backhaul link as follows: ● Backhaul link output power = min(maximum total power, input power × amplification gain) (for example, the backhaul link output power is configured to be the smaller of the product of the maximum total power or the input power multiplied by the (configured) amplification gain).

[0061] In such cases, the SN306 can determine or calculate the output power of the C-link by using at least one of the following techniques / methods / calculations:

[0062] Exemplary Technique 1 The output power of the C-link can be determined as follows: ● C-link output power = min(maximum total power - backhaul link output power, C-link power) (for example, the smaller of the maximum total power minus the second power and / or the first power specific to the type of first signal).

[0063] In this case, the C-link power can be determined / calculated for different signals / channels according to at least one of equations (1) to (4) (for example, the first power value may be specific to the type of signal on the C-link). Since the backhaul link is preferred in this embodiment, the determined C-link power can be compared to, for example, the value obtained by subtracting the backhaul output power from the maximum total power (e.g., maximum total power - backhaul link output power) such that the C-link power is less than or equal to the maximum total power - backhaul link output power.

[0064] Exemplary Technique 2 The SN306 can determine the output power of the C-link as follows: ● C-link output power = C-link power - power offset (for example, the value obtained by subtracting the power offset from the first power value specific to the first signal type).

[0065] In this case, the C-link power can be determined for different signals / channels according to at least one of equations (1) to (4) (for example, the C-link power may be specific to the type of signal on the C-link). The power offset can be at least one of the following values: C-link power + backhaul link output power - maximum total power (for example, the value obtained by adding the determined second power to the C-link power and subtracting the maximum total power), a fixed value, and / or a value determined by BS102.

[0066] Exemplary Embodiment 4: The BS transmits power control indications to the SN to adjust the output power of the backhaul link. In various embodiments, BS102 may transmit power control indications to SN306 for adjusting the output power of the backhaul link (e.g., second power) to ensure that the sum of the power of the C-link and backhaul link is below / less than or equal to (not exceed) the total maximum power constraint. SN306 may receive indications (e.g., power control indications) from BS102 for adjusting the backhaul link power. SN306 may adjust the backhaul link power according to the power control indications. Power control indications (e.g., for controlling backhaul link power) may include indications of at least one of the following: transmission power, amplification gain, frequency resources, and / or time resources.

[0067] Transmission power In some configurations, if the transmission power (e.g., backhaul link power or second power) is specified (e.g., power control indication may include indication of transmission power), the amplification gain can be determined / calculated as amplification gain = transmission power / input power (e.g., the transmission power value divided by the input power from UE104 to SN306). The sum of the transmission power of the backhaul link and C-link may / should be less than / should be less than the maximum total power (e.g., total maximum power constraint or maximum power threshold).

[0068] Amplification gain In some configurations, if the amplification gain is specified (e.g., included in power control indication), the SN306 can determine / calculate the transmission power (e.g., backhaul link power) as follows: ● Transmission power = min(maximum total power - C-link power, input power × amplification gain) (for example, the smaller of the product of the maximum total power minus the value of a first power specific to the first signal type, and / or the input power to SN306 multiplied by the amplification gain configured for SN306).

[0069] The SN306's amplification gain can be adjusted to satisfy the following constraints. ● Input power × Actual gain <= Maximum total power - C-link power (for example, the input power multiplied by the actual gain is less than or equal to the value obtained by subtracting the first power from the maximum total power).

[0072] Referring here to Figure 6, a flowchart of Method 600 for simultaneous backhaul link and control link transmission for a network node (e.g., SN) is shown. Method 600 can be implemented using any of the components and devices detailed herein in relation to Figures 1 to 5. In summary, Method 600 may include determining a first power and a second power (602). Method 600 may include transmitting a first signal over a control link (604). Method 600 may include transferring a second signal over a transport link (606). Method 600 may include receiving a first signal over a control link (608). Method 600 may include the step of receiving a second signal over a transport link (610).

[0073] In operation (602), in some configurations, a network node (e.g., SN) can determine / calculate / calculate a first power of the network node for the control link from the network node to a wireless communication node (e.g., BS, gNB, eNB, or TRP) (e.g., C-link power, or transmission power for / on / in the C-link), and a second power of the network node for the forwarding link from the network node to a wireless communication node (e.g., F1, backhaul link) (e.g., backhaul link power, or transmission power for / on / in the backhaul link).

[0074] In some configurations, a network node can perform at least one of operations (604) and / or (606). In operation (604), the network node can transmit / transmit / provide / signal / communicate a first signal / message over a control link from the network node to the wireless communication node. In operation (606), the network node can forward / transmit a second signal over a forwarding link from the network node to the wireless communication node. In response to at least one of operations (604) and / or (606), BS102 can receive / acquire / obtain at least one of the first signal over the control link from the network node to the wireless communication node in operation (608), and / or the second signal over the forwarding link from the network node to the wireless communication node in operation (610).

[0075] In various embodiments, when transmissions on the control link and transmissions on the forwarding link occur simultaneously (e.g., overlapping in time), at least one of the following may be possible: a first power may be lower than or equal to a first maximum power configured for the control link, and / or a second power may be lower than or equal to a second maximum power configured for the forwarding link. The first maximum power (e.g., a maximum power constraint) may be different from the second maximum power.

[0076] In some embodiments, when transmission on a control link and transmission on a forwarding link occur simultaneously, at least one of several methods / scenarios (e.g., a first method, a second method, etc.) can be supported / utilized / implemented. In the first method / scenario, the sum of the first maximum power (e.g., the maximum power of the C-link) and the second maximum power (e.g., the maximum power of the backhaul link) can be less than or equal to the total maximum power (e.g., the C-link and backhaul link can share or be associated with one total maximum power constraint, or can be associated with the same RF component). The total maximum power can be part of the network node's capacity. For example, the network node's hardware and / or software can constrain / limit / bound the peak output power to a certain value (e.g., total maximum power). In the second method / scenario, the first maximum power may be independent of the second maximum power (e.g., the C-link and backhaul link may have separate maximum power constraints, and for example, the C-link and backhaul link may have separate RF components). For example, if a network node supports the first method / scenario, the sum of the first and second maximum powers may be lower than the total maximum power constraint. If a network node supports the second method / scenario, the first and second maximum powers may not be related (for example, the maximum power constraints for C-links and backhaul links are not related). In this case, there may be no total maximum power constraint. In the third method / scenario, at least one of the first power maximum or the second power maximum can be comprised of a wireless communication node. In the fourth method / scenario, at least one of the first power maximum or the second power maximum can be calculated / determined / based on / according to / by / the total maximum power minus the other of the first power maximum or the second power maximum. The total maximum power may be part of the network node's capacity.In some configurations, two or more methods can be combined or supported depending on the capacity or support of the network nodes, such as the first method and the third method, the first method and the fourth method, or the third capacity and the fourth method.

[0077] In some embodiments, when the sum of the first power and the second power exceeds the total maximum power (e.g., the total maximum power constraint between the C link and the backhaul link), and / or when transmission on the control link and transmission on the forwarding link occur simultaneously, the network node may decide to perform A, perform B, or perform one of A or B (according to a prioritization rule).

[0078] For example, to implement A, a network node may decide not to allocate power to the second power and / or not to perform the forwarding / transmission of the second signal (e.g., prioritizing the control link and / or dropping the backhaul link). To implement B, a network node may decide not to allocate power to the first power or not to transmit the first signal (e.g., prioritizing the backhaul link and / or dropping the C link). In some cases, a network node may decide to implement A or B according to or based on a prioritization rule (e.g., a predefined rule). Implementing A or B may include performing transmissions on the C link and backhaul link according to the prioritization rule.

[0079] In various configurations, a prioritization rule can instruct the transmission or transfer of at least one signal having the highest priority among the signals that match the candidate signals identified in the prioritization rule. In some embodiments, the prioritization rule can identify at least one of the following candidate signals for a first signal (e.g., a control link) as having a higher priority than candidate signals for a second signal: namely, physical random access channel (PRACH) transmission, physical uplink control channel (PUCCH) transmission, PUCCH transmission with hybrid automatic retransmission request acknowledgment (HARQ-ACK) information, physical uplink shared channel (PUSCH) transmission with HARQ-ACK information, sounding reference signal (SRS), PUCCH transmission with status report, and / or PUSCH transmission with status report. For example, if the first signal includes / contains at least one of the above-mentioned specific types of signals (e.g., and / or messages or information) having a higher priority than candidate signals for the second signal, the network node may prioritize the first signal for C-link transmission and drop the second signal. If the first signal is not included in the prioritization rules, or contains other types of signals outside of the prioritization rules, the network node may prioritize the second signal for backhaul link transmission, thereby dropping the first signal.

[0080] In some embodiments, the prioritization rule may identify at least one of the following candidate signals for the first signal, namely, signals other than physical random access channel (PRACH) transmissions, signals other than physical uplink control channel (PUCCH) transmissions, signals other than PUCCH transmissions with hybrid automatic retransmission request acknowledgment (HARQ-ACK) information, signals other than physical uplink shared channel (PUSCH) transmissions with HARQ-ACK information, signals other than sounding reference signals (SRS), signals other than PUCCH transmissions with status reports, and / or signals other than PUSCH transmissions with status reports, as having a lower priority than the candidate signals for the second signal. For example, if the first signal includes / contains at least one of the above-mentioned specific types of signals (e.g., and / or messages or information) that have a lower priority than the candidate signals for the second signal, the network node may prioritize the second signal for backhaul link transmission and drop the first signal. If the first signal is not included in the prioritization rules, or if it includes other types of signals outside the prioritization rules (for example, for a lower priority than the second signal in this case), the network node may prioritize the first signal, for example, for C-link transmission, thereby dropping the second signal.

[0081] In some embodiments, the prioritization rule is to prioritize, in descending order of priority, the first candidate signal for the first signal (e.g., a C-link signal), the second candidate signal for the second signal (e.g., a backhaul link signal), and the third candidate signal for the first signal (e.g., another C-link signal), for example, the following: {Physical Random Access Channel (PRACH) transmission or Physical Uplink Control Channel (PUCCH) transmission; any signal (e.g., a backhaul link signal); signals other than PRACH transmission or PUCCH transmission}, or {P RACH transmission, or PUCCH transmission with Hybrid Automatic Retransmission Request Acknowledgment (HARQ-ACK) information; any signal; a signal other than PRACH transmission or PUCCH transmission with HARQ-ACK information}, or {PRACH transmission, PUCCH transmission with HARQ-ACK information, or Physical Uplink Shared Channel (PUSCH) transmission with HARQ-ACK information; any signal; a signal other than PRACH transmission, PUCCH transmission with HARQ-ACK information, or PUSCH transmission with HARQ-ACK information}, or {HARQ-A PUCCH transmission with CK information; any signal; a signal other than PUCCH transmission with HARQ-ACK information}, or {PUCCH transmission with HARQ-ACK information, or physical uplink shared channel (PUSCH) transmission with HARQ-ACK information; any signal; a signal other than PUCCH transmission with HARQ-ACK information or PUSCH transmission with HARQ-ACK information}, or {PUCCH transmission with HARQ-ACK, or sounding reference signal (SRS) information; any signal; PUCCH transmission with HARQ-ACK information} Signals other than transmission or SRS}, or {PRACH transmission, PUCCH transmission with HARQ-ACK information, or SRS; any signal; PRACH transmission, PUCCH transmission with HARQ-ACK information, or signals other than SRS}, or {PRACH transmission, or PUCCH transmission with status report; any signal; signals other than PRACH transmission or PUCCH transmission with status report}, or {PRACH transmission, PUCCH transmission with status report, or PUSCH transmission with status report; any signal;It can be identified as containing one of the following signals: PRACH transmission, PUCCH transmission with status report, or a signal other than PUSCH transmission with status report.

[0082] In some configurations, if a network node decides to perform B (for example, drop the first signal), the network node may transmit / retransmit the first signal (for example, another C-link signal or the dropped first signal) using frequency domain resources allocated to the first signal that had not been previously forwarded / transmitted (for example, the same frequency domain resources as the dropped first signal that were about to be transmitted simultaneously with the second signal).

[0083] In some embodiments, if the first signal comprises / includes a physical random access channel (PRACH) transmission, at least one of the following may be possible: the network node may transmit a PRACH transmission in the next random access channel (RACH) opportunity (RO); the network node may transmit a PRACH transmission in the next PRACH slot; and / or the network node may transmit a PRACH transmission according to a synchronous signal block (SSB) determined by the network node and the relationship between the SSB and the PRACH transmission. In some embodiments, if the first signal includes a physical uplink control channel (PUCCH) transmission, a physical uplink shared channel (PUSCH) transmission, and / or a sounding reference signal (SRS), then at least one of the following may be possible: the network node may transmit the first signal (e.g., a signal on a C-link) in the next slot; the network node may transmit the first signal in the next uplink slot; the network node may transmit the first signal in a time-domain resource according to an indication from a wireless communication node; and / or the network node may transmit the first signal after a defined / configured / predetermined duration.

[0084] In some configurations, a network node may decide to prioritize the transmission of a first signal (e.g., a C-link signal) for simultaneous transmission on both the C-link and the backhaul link. In this case, the network node may reduce / decrease the second power (e.g., backhaul link output power) to the smaller of the following two values: the maximum total power minus the first power (e.g., C-link power), and / or the input power to the network node (e.g., from a wireless communication device such as a UE) multiplied by the configured (amplified) gain of the network node (e.g., a minimum value). The configured gain may refer to the amplified gain or the maximum gain without adjustment.

[0085] In some embodiments, a network node can adjust / modify its actual gain so that the input power multiplied by the actual gain is less than or equal to the maximum total power minus the first power. A network node can adjust its actual gain so that the total power output by the network node does not exceed a maximum power threshold.

[0086] In some configurations, a network node may decide to prioritize the transmission of a second signal (e.g., a backhaul link signal). In this case, the network node may decide that the second power (e.g., backhaul link output power) is the smaller of the maximum total power and / or the input power to the network node multiplied by the network node's configured gain. In some embodiments, the network node may decide that the first power (e.g., C-link output power) is the smaller of the value obtained by subtracting the second power (e.g., backhaul link output power) from the maximum total power and / or the value of the first power specific to the type of first signal (e.g., C-link power which can be calculated using at least one of equations (1) to (4) for different signals / channels) (e.g., the minimum value).

[0087] In some embodiments, a network node may determine a first power (e.g., C-link output power) as a value obtained by subtracting a power offset from a first power (e.g., C-link power) specific to a first signal type. The power offset may be at least one of the following: a fixed value, and / or a value determined by the wireless communication node, which is greater than or equal to the value obtained by adding a determined second power (e.g., backhaul link power) to the first power (e.g., C-link power) specific to a first signal type, and subtracting the maximum total power (e.g., total maximum power constraint).

[0088] In some configurations, network nodes can receive / acquire / obtain indications to adjust a second power (e.g., backhaul link power) to prioritize a first signal on a C-link, for example. The network nodes can adjust the second power according to the indication. For example, the indication may include at least one of the following: ● At least one of the following may be possible: indication of the transmission power value of the second power, the gain of the network node can be determined based on / by the transmission power value divided by the input power to the network node, and / or the sum of the transmission power value and the first power may be less than the maximum total power. ● Indication of gain, the second power may be the smaller of the following: the maximum total power minus the value of the first power specific to the first signal type (e.g., calculated C-link power), and / or the input power to the network node multiplied by the configured gain of the network node (e.g., minimum value); and / or the gain may be such that the input power multiplied by the (actual) gain is less than or equal to the value of the maximum total power minus the first power (e.g., C-link power). ● Indication of a second power frequency domain resource. This indication may include at least one of the following: frequency offset, resource block (RB) number or resource element (RE) number, bandwidth portion (BWP) index, bandwidth index, and / or frequency domain resource allocation (FDRA) indicator, and / or ● Indication of a second power time-domain resource. This indication may include at least one of the following: slot offset, symbol offset, duration, periodicity, system frame number (SFN), start and length indicator values ​​(SLIV), number of absolute time units, and / or absolute time units.
