Embodiments of unified wireless architecture are disclosed to support multiple types of outer transceiver operation across different wireless standards. In the unified wireless architecture, processing chains of different RAT specifications may be configured using a single digital signal processing or hardware accelerator chain. An interface/boundary between a signal processing engine (SPE) and an outer transceiver (OTRX) may be identified as complex number data samples for all RATs. The OTRX may take RAT-specific unique processing steps away from SPE. Pipelined hardware Accelerator blocks may be configured to perform operations across different RATs with controls over bandwidth, latency, and power.

System and method embodiments are disclosed for merging computing hardware datapath to reduce energy consumption and improve throughput of modem signal processing functions on a Modem. Compute-in-memory (CIM) is used for data access and processing in parallel using processing elements integrated within memory chip. The processing throughput may significantly improve since data is accessed directly from the computational memory storage in parallel for processing and the clock speed for data processing may run at a higher spec than conventional approaches. Energy consumption for Modem processing is also reduced.

With advanced compute capabilities and growing convergence of wireless standards, there is requirement to run multiple wireless standards, e.g., 4G, 5G, and Wi-Fi, on a single hardware together. Typical solution includes reserving some computing resources for specific wireless standards. Such a resource strategy may not be optimized or efficient according to the real needs for various wireless standards. The present disclosure presents embodiments of using a unified resource controller to take multiple scheduling inputs across various wireless standards, allocate resources among a plurality of configurable processing units, and manage hardware components for data path accelerations including forward error correction, and signal processing implementation. The multiplexing multiple wireless technologies based on spectral utilization may improve the efficiency in power consumption and hardware resources utilization.

System and method embodiments are disclosed for wireless channel information sharing to improve system performance in a wireless communication system. A software convergence layer is incorporated to query and keep track of all clients connected with the wireless communication system through different wireless technologies, such as 5G and/or WLAN. The shared channel information may be modeled into a set of coordinates. For each coordinate, a set of operational parameters, such as beamforming weights, Tx and Rx rate, Tx power, and Rx gain on a per-channel basis are determined. These operational parameters are passed onto schedulers of the different wireless technologies, which then use these operational parameters when clients are around corresponding coordinates.

Systems and methods for wireless channel information sharing

With advanced compute capabilities and growing convergence of wireless standards, it is desirable to run multiple wireless standards, e.g., 4G, 5G NR, and Wi-Fi, on a single signal processing system, e.g., a system on a chip (SoC). Such an implementation may require simultaneously receiving and transmitting signals corresponding to each wireless standard and also signal processing according to respective requirements. Typical solutions involve providing separate hardware blocks specific to each wireless standard, which in turn requires more area on the SoC and consumes more power. Embodiments of the present disclosure provide a unified hardware that may process signals across different standards in both a transmitting direction and a receiving direction simultaneously.

Advances in wireless technologies have resulted in the ability of a 5G communication system to support multiple wireless communication applications. Each of these applications requires special handling in all layers and more so in scheduler and physical layer. The present disclosure presents embodiments of dynamical creating a computation instance with a slice of resources allocated for each scheduling input. Each computation instance may be independently managed, controlled, and customized according to the specific requirements of the corresponding scheduling input. Such a dynamic resource allocation allows large number of slices in PHY layer. Furthermore, when overloading happens, one scheduling inputs may be migrated from one distribution unit (DU) to another DU without interruption for end users during scheduling migration. Accordingly, efficiency and robustness of a 5G communication system may be improved to serve multiple wireless communication applications.

A method, an apparatus and a computer program product for enhancing reception of signals in a wireless communication system. A signal containing a frame including a plurality of symbols is received on an uplink communication channel. An angular position of at least one symbol in the plurality of symbols in a constellation of symbols is detected. The plurality of symbols include equalized symbols. An angular difference corresponding a phase error between the detected angular position of the symbol and an expected reference angular position in the constellation of symbols corresponding to an expected reference symbol corresponding to the received frame is determined. Using the determined phase error, a phase of the symbol is compensated.

Advances in wireless technologies have resulted in the ability of a wireless communication system to support wireless communications of different standards, e.g., 5G, LTE, and Wi-Fi. Different Wireless standards have aspects which are very different from each other. Described in the present disclosure are embodiments of architecture with hardware and software split to allow implementation of different wireless standards along a configurable signal process path. The configurable signal process path comprises software configurable operators that may be configured in a desired level of granularity to load desirable software to process signals of various standards on the same hardware. Embodiments of the disclosed architecture with hybrid hardware and software implementation may improve system operation efficiency and lower system complexity to serve communications across multiple wireless standards.

A reliable wireless communication system needs good wireless signal detection and interference management. Traditional thinking for interference management mostly relies on interference cancellation or receiver design. In such a design, an interference issue occurs when a receiver is incapable of handling it. Various interference management embodiments are presented in the disclosure. Using HARQ retransmission incorporated with parameter changes, interference management may be improved through interference source control for more effective signal detection and interference management. Additionally, early termination parameters for decoding operation may be learned and implemented separately or jointly with HARQ retransmission. Furthermore, estimated interference power may be improved using machine-learning algorithm based on decoding statistics of the decoder. Biasing for the estimated interference power may be implemented separately or jointly with early termination parameter learning and/or HARQ retransmission request with parameter changes to improve signal detection and interference management.

Systems and methods for improved detection of signal in wireless system

In a grant based system, a user equipment (UE) sends data in an uplink in a request-grant process. The UE first sending a scheduling request, a gNodeB processing the request and scheduling a grant sometime in future, then UE then either sending data if the grant is sufficient or requesting for another grant with more capacity to accommodate data sending. Such a proceeding could cause serious latency in network access. Described in the present patent disclosure are embodiments to reduce the access time by giving proactive grants through inspecting downlink (DL) data sent to the UE or uplink data being transmitted from the UE. The uplink data may be predictive since it maybe in lieu of requirement for sending a TCP acknowledgement for the DL TCP data scheduled earlier. For voice calls, a ML system for system may be deployed to predict when proactive UL grants may be given.

Systems and methods to reduce network access latency and improve quality of service in wireless communication

In a typical data plane application, there is a packet dispatcher which receives packets from the underlying subsystem for distribution among various threads/processes for further processing. These threads/processes may run on various processing elements (PEs) and pass through multiple stages of processing. As new generation system-on-a-chip (SoC) architectures have multiple heterogeneous clusters with corresponding PEs, packet processing may traverse through multiple PEs in different clusters. Since latencies/performance for different clusters/PEs may be different, packet processing on the SoC may take a variable amount of time, which may lead to unpredictable latencies. The present disclosure provides embodiments to solve the problem of packet processing on heterogeneous clusters/PEs by providing a fast path enabler to the applications for SoC architecture awareness. The fast path enabler understands the cache topology of the SoC and may pre-fetch packets to the desired cache to minimize latencies for improved performance.
