Description

Technical Field

[0001] The following generally relates to the provision of communication services, and more particularly to systems and methods for payload processing in 5G and similar systems.

Background Art

[0002] Data and cellular networks are increasingly evolving to utilize mobile network nodes such as satellites. For example, satellite networks including low Earth orbit (LEO) satellites have been deployed and tested.

[0003] In such communication scenarios, there may be multiple different devices attempting to connect and communicate with each other both on the ground and in space.

[0004] However, in current architectures, an antenna is typically connected to only a single processing entity. An example of this is the use of a reprogrammable processor on a satellite, where the reprogrammable processor is the only device communicating with the antenna or beamformer. This dedicated communication format limits the capabilities of the antenna and the connected devices.

[0005] Therefore, there is a need for improved systems and methods for payload processing in cellular networks that overcome at least some of the drawbacks of existing systems and methods.

[0035] The following generally pertains to the provision of communication services, and in particular to payload processing systems and methods for 5G and similar systems.

[0036] Satellites are expected to be increasingly used in providing data and mobile network services. Therefore, the problem to be solved is how to synchronize communication capabilities across different devices.

[0037] This disclosure relates to a payload processing architecture that flexibly provides digital beamforming to multiple system endpoints. The endpoints may be located on the local satellite, on the ground, or on other satellites. The traffic transmitted by these endpoints may be inherently heterogeneous (e.g., different waveforms). Digital beamforming offers a very high degree of flexibility in terms of bandwidth granularity and the number of beams.

[0038] Advantageously, the techniques described herein may be used to provide highly flexible digital beamforming (e.g., in terms of beam count and bandwidth granularity) that can be shared among multiple system sources / sinks having potentially heterogeneous interfaces.

[0039] Referring to Figure 1, according to one embodiment, a system 100 of an example of a payload processing architecture is shown.

[0040] System 100 includes a set of antenna elements 102.

[0041] Each antenna element 102 may be connected to the uplink / downlink converter 104.

[0042] Multiple such uplink / downlink converters 104 communicate with the frequency-time converter 106.

[0043] In various embodiments, the communication between the uplink / downlink converter 104 and the frequency-time converter 106 is digital communication.

[0044] In various embodiments, communication between the uplink / downlink converter 104 and the frequency-time converter 106 is analog communication.

[0045] In one embodiment, the frequency-time converter 106 is a channelizer.

[0046] The system also includes a set of partial frequency-domain beamformers 108 that communicate with the frequency-time converter 106.

[0047] The partial frequency-domain beamformer 108 offers a high degree of flexibility in the architecture, allowing the processing load to be spread across multiple modules.

[0048] Multiple beamformers 108 are also suitable for supporting redundancy and can be implemented with wireless hardware defined by modern software.

[0049] Although the control mechanism for the beamformer 108 is not shown, it is understood to work in conjunction with the operation of the sample synchronization and distribution fabric 110.

[0050] In one embodiment, the sample synchronization and distribution fabric 110 ensures that the inputs / outputs to this network are time-aligned between all partial beamformers.

[0051] In one embodiment, the sample synchronization and distribution fabric 110 ensures that samples are extracted / inserted into the relevant frequency slots.

[0052] In one embodiment, the sample synchronization and distribution fabric 110 performs splitting / addition across partial beamformers.

[0053] In various embodiments, a split / add box may be used instead of the sample distribution fabric 110.

[0054] The synchronization and distribution fabric 110 connects to one or more sets of processors 112.

[0055] Although only three processors 112 are shown in the diagram, it is reasonable to understand that the number of processors 112 can be arbitrary.

[0056] Various examples of the processor 112 type may be used in this architecture.

[0057] In one embodiment, the processor 112 includes a channelizer that multiplexes into / from a transparent feeder link.

[0058] In one embodiment, the processor 112 includes a sample packetizer (depacketizer) and a compander that enable samples to be transmitted across a network.

[0059] In various embodiments, the processor 112 uses level control.

[0060] In various embodiments, in this example, level control is a shared resource.

[0061] Each processor 112 provides a source / sink 114 for the sample.

[0062] In one embodiment, the processor 112 may be an "internal" function overall (e.g., onboard storage or multiplexing to an RF link).

[0063] In one embodiment, the processor 112 may be connected to the network 116 to provide inputs and outputs to the processor 112.

[0064] In various embodiments, the network 116 may connect to other satellites via intersatellite links and / or to the ground, for example, via a feeder network.

[0065] Referring to Figure 2, according to one embodiment, an example of a magnified view of the sample synchronization and distribution fabric 110 in Figure 1 is shown therein.

[0066] In the sample synchronization and distribution fabric 110, in the transmission scenario 170, data flows from left to right.

[0067] Similarly, in receiving scenario 172, the data flows from right to left.

[0068] In some embodiments, both the receiving scenario 172 and the transmitting scenario 170 are implemented using the same device or components.

[0069] The sample synchronization and distribution fabric 110 includes a core field-programmable gate array (FPGA) 152 and a plurality of beamforming FPGAs 154.

[0070] In one embodiment, the number of beamforming FPGAs 154 is 3.

[0071] The core FPGA 152 includes a time alignment and distribution mechanism 156.

[0072] In one embodiment, the satellite interfaces with the ground via an ORAN 7-2 / 7-3 interface 160 (e.g., a gateway link modem 164).

[0073] This is essentially a packet format for symbols (transmit) and samples (receive). The ORAN interface 160 block converts between the standard ORAN interface 160 and frequency granules.

[0074] In one embodiment, the time alignment mechanism 156 is used to align time between different sources and sinks.

[0075] In one embodiment, the satellite uses a transparent interface to interface with the ground.

[0076] In one embodiment, the ORAN 7-2 / 7-3 interface 158 is used to interface with the Optical Intra-Satellite Link (OISL) 162.

[0077] Unlike ground systems, the systems described here can have fundamentally different latencies (for example, routes via OISL162 generally have higher latencies).

[0078] Once aligned, the frequency granules are distributed to three parallel beamforming chains 154 that perform beamforming by a time alignment and distribution mechanism 156.

[0079] In one embodiment, each beamforming FPGA 154 includes a frequency granule beamformer 166.

[0080] In one embodiment, each beamforming FPGA 154 includes an element channelizer 168.

[0081] In reception scenario 172, mapping from beamformer chain 154 is performed via partial beam summation.

[0082] Another application of the present disclosure may be implemented in a purely regenerative system of 5G New Radio (5G-NR) with uniform subcarrier spacing.

[0083] In various embodiments, the frequency-time conversion includes an (inverse) Fast Fourier Transform with the addition / removal of cyclic prefixes.

[0084] In various embodiments, the frequency-time conversion further includes filtering of the modulated OFDM waveform.

[0085] In such embodiments, the beamformer may be operated on a subcarrier.

[0086] In one embodiment, the processor may optionally include an ORAN fronthaul interface to the high PHY, and upper stack components on the ground or another satellite transmitted by inter-satellite link connections and / or feeder links.

[0087] In one embodiment, the processor may optionally include a local high PHY that performs onboard regeneration, and upper stack components on the ground or another satellite transmitted by intersatellite link connections and / or feeder links.

[0088] Furthermore, the system and applications may include processors for different use cases (e.g., reproducible 5G processing and any combination of transparent waveforms).

[0089] In various embodiments, the detailed signal processing for frequency-time conversion may need to be modified to fit the context of the use case, but the operating principles and beamformer principles may remain the same.

[0090] Advantageously, the technology described here allows for the multiplexing of different devices on the same antenna. As a result, the need for expensive equipment such as channelizers is largely eliminated, leading to cost savings.

[0091] Referring to Figure 3, one embodiment shows a method 300 for processing the payload of a transmission scenario in a cellular network.

[0092] Method 300 may be encoded as a computer executable instruction and executed by one or more computing devices including one or more processors. In one embodiment, Method 300 may be executed by the various components shown in Figures 1 and 2.
