[0029] Overview of a Radio Access Network (RAN) FIG. 1A illustrates an exemplary wireless communication system 100. The wireless communication system 100 includes one or more wireless devices 102, a radio access network (RAN) 104, and a core network (CN) 106. As used herein, RAN 104 generally refers to a network used as part of the wireless communication system 100. RAN 104 can be used to connect one or more wireless devices 102, such as cellular phones, to the CN 106 of the communication system 100.

[0030] FIG. 1B illustrates an example of RAN 104. In some embodiments, RAN 104 can include a baseband unit (BBU) 112 connected to one or more remote radio units (RRUs) 110 positioned near one or more antennas 108. BBU 112 can be configured to communicate with CN 106, while antenna 108 can be configured to communicate with wireless device 102.

[0031] Figure 2 illustrates an example of an O-RAN 200 that can be used as part of a telecommunications system. As used herein, O-RAN 200 generally refers to a type of RAN that can employ Ethernet, among other things, for communication between the components of the O-RAN 200. In some embodiments, the BBU from the RAN can be replaced with two components within the O-RAN 200, a distributed unit (DU, also referred to as O-DU) 202 and a central unit (CU, also referred to as O-CU) 204. In some embodiments, the distributed unit 202 and the central unit 204 can be connected and communicate via Ethernet.

[0032] The O-RAN 200 can communicate separate control plane (CP) and user plane (UP) information, transmitted or received using radio frequency (RF) signals, with a radio unit (RU, also referred to as O-RU) 110. The control plane can be used to communicate the presence or absence of downlink data scheduling. The user plane can provide the data to be transmitted. As described herein, the radio unit 110 can include an RF circuit configured to amplify and / or convert user plane data into an RF signal transmitted by one or more antennas 108. In some embodiments, the RF circuit can include, for example, a fast Fourier transform (FFT) block, a digital-to-analog converter (DAC), a mixer, a variable gain amplifier, a phase adjuster, a power amplifier, and the like. The transmission path can consume a relatively large amount of power to amplify the RF signal to a power sufficient for the distance used for wireless RF communication. Thus, the power consumption of the O-RAN 200 can be reduced by turning off the transmission path when the transmission path is not currently being used for RF communication.

[0033] The use of Ethernet within O-RAN200 can pose certain challenges. For example, since Ethernet is a packet-based communication standard, individual packets can be lost. This can lead to undesirable functionality in the system if components such as the radio unit 110 do not receive the expected lost data packets.

[0034] O-RAN200 can also employ discontinuous transmission (DTX) to reduce power consumption when a radio frequency signal is not being transmitted by a given antenna 108 or channel of the radio unit 110. O-RAN200 can also employ discontinuous reception (DRX) to protect sensitive components when a radio frequency signal is not being received by a given antenna 108 or channel of the radio unit 110.

[0035] Discontinuous Transmission Signaling in O-RAN Figure 3 provides an illustration of the communication between the distributed unit 202 and the radio unit 110 when transmitting a radio frequency signal using the O-RAN200 system. The distributed unit 202 can provide a discontinuous transmission signal, i.e., a DTX signal, which can be used by the radio unit 110 to turn off certain components of the RF circuitry of the corresponding channel or transmission path of the radio unit 110 when there is no data being transmitted wirelessly (e.g., data within the user plane).

[0036] The state of the discontinuous transmission signal can be directly determined or derived from a predetermined schedule (e.g., time division duplex or TDD transmission / reception schedule) or control information such as real-time control information. In the context of O-RAN, an Ethernet-based network can provide control plane and user plane information to the radio unit 110 via, for example, the distributed unit 202. The control plane can be used to signal or indicate the absence or presence of downlink data scheduling to follow within the user plane. The user plane can provide the data to be transmitted.

[0037] However, relying on a control or predetermined schedule to drive discontinuous transmission signaling may not be as accurate as directly relying on the user data included in the user plane. This is especially true when using a packet-based network such as Ethernet, because the corresponding control plane packet is received by the radio unit 110 while the packet containing the user data may be lost or discarded last. This can result in the radio unit 110 being instructed to maintain an active transmission path even when no data is received on the user plane. The transmission path may consume a relatively large amount of power to transmit RF signals over the distance used for wireless RF communication. Thus, when the transmission path remains on without transmitting any data, these transmission paths can consume power without transmitting any RF signals.

[0038] Figure 3 illustrates one exemplary situation where, due to packet loss, one or more transmission paths of the radio unit 110 can remain on when a packet containing user plane data is lost. In particular, the distributed unit 202 can provide the control plane message 302 for a plurality of symbols M, M + 1, …, N to the radio unit 110. The distributed unit 202 can also provide the packet 304 M , 304M+1 、…、304 N can be provided to the radio unit 110. In some embodiments, the control plane message 302 and the packet 304 M 、304 M+1 、…、304 N each may experience a certain network delay 306 between being output from the distributed unit 202 and being received by the radio unit 110. The time delay 308 between receiving the control plane message 302 and receiving the first packet 304 M may be the minimum amount of time that the radio unit 110 has to prepare to process the first packet 304 M received from the distributed unit 202.

[0039] In one example, the packet 304 M+1 including user plane data for symbol M + 1 may be lost. However, since the control plane data 302 indicates that the distributed unit 202 transmits the packet 304 M+1 along with the user plane data for symbol M + 1, the radio unit 110 may leave the corresponding transmission path based on the control plane data 302 even if the user plane data for symbol M + 1 is not received at the expected time.

[0040] Aspects of the present disclosure can enhance the efficiency of the radio unit 110 by directly deriving a discontinuous transmission state from user plane data and turning off the transmission path when there is no data on the user plane. In some embodiments, the transmission path can be turned off by biasing a power amplifier used to amplify the RF transmission signal to an off state. By directly deriving the discontinuous transmission state from user plane data, in situations such as congestion in an Ethernet-based network that can cause user plane data stops, the radio unit 110 can assert the discontinuous transmission state to conserve power. On the other hand, in embodiments where the discontinuous transmission state is derived from a predetermined schedule or control plane 302 information, the radio unit 110 may maintain an active transmission state even when no data is received on the user plane.

[0041] FIG. 4A illustrates one exemplary embodiment of a radio unit 110 according to aspects of the present disclosure. FIG. 4B illustrates one exemplary embodiment of the connections between the components of the radio unit 110 according to aspects of the present disclosure. Referring to FIGS. 4A and 4B, the radio unit 110 includes a radio head 402 (also referred to as a radio frequency integrated circuit (RFIC)). The radio head 402 includes an input section 404 (e.g., an Ethernet port), a data jitter buffer 406, a plurality of transmission paths 408, a discontinuous transmission state monitoring component 410, one or more discontinuous transmission control outputs 412, and one or more RF outputs 414. The input section 404 is configured to receive a packet 304 including user plane data 418. In some embodiments, the user plane data 418 can include frequency domain IQ samples. However, in other embodiments, the user data 418 can be provided in other forms without departing from the aspects of the present disclosure.

[0042] The data jitter buffer 406 is configured to buffer the user plane data 418 so that, for example, jitter introduced by Ethernet communication does not affect components downstream from the data jitter buffer 406. The data jitter buffer 406 can provide the buffered user plane data 418 to the transmission path 408 and the discontinuous transmission monitoring component 410 at a rate expected by the transmission path 408. In some embodiments, the data jitter buffer 406 can provide the buffered user plane data 418 at a substantially constant rate.

[0043] The transmission path 408 is configured to receive the user plane data 418 from the data jitter buffer 406 and amplify / convert the data into an RF signal that can be transmitted by one or more antennas 108. In some embodiments, each of the transmission paths 408 can include an FFT block, a digital-to-analog converter (DAC), a mixer, a variable gain amplifier, a phase adjuster, a power amplifier 420, and the like. These components can be configured to convert the frequency domain IQ samples of the user data into an analog signal in RF that can be transmitted by the antenna. The transmission path 408 can have a substantially constant latency between receiving data from the data jitter buffer 406 and outputting the RF data to the antenna via the RF output 414. In some embodiments, each of the transmission paths 408 can be coupled to a corresponding one of the antennas 108 via a physical antenna path.

[0044] The discontinuous transmission monitoring component 410 is configured to determine or derive a discontinuous transmission state from the user plane data 418 received from the data jitter block 406. For example, the discontinuous transmission monitoring component 410 can determine or derive a first discontinuous transmission state in which the corresponding transmission path 408 is turned off in response to the user plane not containing data. In some cases, when a control plane message indicates that user plane messages are not scheduled, the user plane may not contain data. In other cases, when packets containing user plane data are lost, the user plane may not contain data.

[0045] Similarly, the discontinuous transmission monitoring component 410 can determine or derive a second discontinuous transmission state in which the corresponding transmission path is turned on in response to the user plane data 418 containing data to be transmitted. The discontinuous transmission monitoring component 410 can then generate a plurality of discontinuous transmission control signals indicating the determined discontinuous transmission state. Each of the discontinuous transmission signals can correspond to one of the RF outputs 414 generated by the transmission path 408. The discontinuous transmission monitoring component 410 can also provide the discontinuous transmission control signal to the corresponding transmission path 408. For example, as shown in FIG. 4B, the discontinuous transmission monitoring component 410 can provide a discontinuous transmission control signal to the power amplifier 420 (and / or a power amplifier downstream from the RF output 414) included in the transmission path 408 so as to be able to turn off the transmission path 408 when there is no user data to be transmitted.

[0046] Depending on the embodiment, the discontinuous transmission monitoring component 410 can be implemented in hardware (e.g., using discrete circuitry) and / or software operating on a processor or other circuit (e.g., a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device).

[0047] By monitoring the transfer of user plane data to the constant waiting time transmission path 408 within the radio unit 110, the discontinuous transmission monitoring component 410 can determine or derive the discontinuous transmission state independently for each physical antenna path / transmission path 408. The radio unit 110 can output a discontinuous transmission state control signal for each antenna path with a delay configurable to match MISC.

[0048] Figure 5 illustrates a method 500 for determining or deriving a discontinuous transmission state according to an aspect of the present disclosure. One or more blocks of the method 500 can be implemented, for example, by a radio unit (e.g., radio unit 110 of FIG. 4) and / or an O-RAN (e.g., O-RAN 200 of FIG. 2).

[0049] In block 502, the input section of the radio unit can receive a plurality of packets. At least one of the packets can include user plane data. In some embodiments, the input section can include an Ethernet port configured to receive packets.

[0050] In block 504, one or more transmission paths can process the user plane data to generate one or more RF transmission signals. The transmission path can include one or more power amplifiers configured to amplify the RF transmission signal to a power level sufficient for wireless communication. In block 506, one or more antennas can transmit the RF transmission signal.

[0051] In block 508, the radio unit can determine the discontinuous transmission state for each of the one or more transmission paths based on the user plane data. In some embodiments, the radio unit can include a discontinuous transmission monitoring component configured to determine the discontinuous transmission state. The power amplifier can be turned on or off based on the determined discontinuous transmission state and configured to save power.
