Definitions

  • the present disclosure relates to estimated future transmission activity of a communication device in a communication network, and more particularly to methods and related devices and nodes supporting determining and signalling the estimate.
  • Next-generation random access protocols must support the connectivity of massive mobile devices.
  • Current random-access protocols adopted in fifth generation (5G) narrowband-internet of Things (NB-loT) follow a grant-based design.
  • Each active user equipment (UE) first selects a preamble (that is, an information sequence) from a predefined set of preambles and reports its access intention and status information (e.g., buffer size) to an access point (AP).
  • the AP authorizes the granted communication devices to send their connection requests in the next step.
  • the AP allocates the resource blocks to the granted communication devices so that they can access the network without contention.
  • This four-stage grant-based random-access protocol creates a high signaling overhead, which makes it inefficient for large-scale loT networks with massive devices.
  • the terms "user equipment”, “UE”, or “mobile device” herein may be interchangeable with and replaced with the term "communication device”; and the terms “access point” or “AP” herein may be interchangeable with and replaced with the term “network
  • Grant-free massive access has arisen as an alternative approach for flexible random access with reduced latency and signaling overhead.
  • This approach may allow the communication devices to access the network without requesting a grant prior to transmission.
  • this may result in a high probability of pilot collision unless the channel coherence is long enough that all communication devices can be allocated mutually orthogonal pilots, which is typically not the case in practice.
  • the devices are allocated non-orthogonal pilots. Resolving pilot collisions is critical in grant-free massive access, especially in Ultra-Reliable Low-Latency Communication (URLLC) scenarios.
  • URLLC Ultra-Reliable Low-Latency Communication
  • Massive MIMO may bring new opportunities to exploit the spatial degrees of freedom to improve collision resolution.
  • Massive MIMO may also offer other advantages such as a large array gain and channel hardening effects.
  • Some algorithms for device activity detection (and joint device activity detection) for massive MIMO with grant-free access may offer some performance (e.g., see Liu, L., Larsson, E. G., Yu, W., Popovski, P., Stefanovic, C, & De Carvalho, E., Sparse signal processing for grant-free massive connectivity: A future paradigm for random access protocols in the Internet of Things. IEEE Signal Processing Magazine, 2018).
  • Uplink configured grants may be another approach. Dynamic scheduling of uplink transmissions is the main mode of operation in Long Term Evolution (LTE) and new radio (NR). While this may be a flexible scheduling solution, it may have a large overhead in terms of signaling. In LTE and NR, there are also some mechanisms to reduce the signaling load such as "configured grant type 1" and "configured grant type 2".
  • a configured uplink grant type 1 can be provided to the UE by radio resource control (RRC). Once activated by RRC, the UE may make periodic transmissions (without any additional explicit grants) with a configured periodicity, time-offset, frequency resources and a modulation and coding scheme.
  • RRC radio resource control
  • a configured uplink grant type 2 is similar, but activation and deactivation is done with L1/L2 control signaling (using the physical downlink control channel (PDCCH)) instead of with RRC signaling.
  • Certain aspects of the disclosure and their embodiments may provide solutions to these or other challenges.
  • Various embodiments include a type of uplink signaling by which a communication device sends statistical predictions on how likely it is to transmit at given points in the future.
  • these predictions may also contain information about additional statistics related to transmissions, e.g., packet size distribution, priority class, latency requirements, error tolerance, etc.
  • packet size distribution e.g., packet size distribution, priority class, latency requirements, error tolerance, etc.
  • a vast amount of data that the communication device has access to e.g., video streams, sensor data, battery status, or other information
  • that would nominally be infeasible to convey to an AP is condensed into a message that provides the AP with side information about the communication device's future behavior which in turn can aid device activity detection.
  • Performance may be improved in device activity detection in grant-free random access, e.g., probability of detection versus probability of false alarm. Such improvement may, in turn, lead to improved overall throughput, lower latency, and higher relatability. Additional potential technical advantages may include that knowledge related to future traffic also may provide more time for the network to adapt its operational states, e.g., to activate more resources (frequency bands, base stations, antenna elements, RAN compute capacity, etc.) before an actual overload situation occurs. Thus, more robust network performance and a better user experience may be achieved.

  • communication devices may have predictable activity patterns. Knowledge of these patterns may be exploited as additional information in the device activity detection to improve its performance. However, typically, it may be difficult to learn such user behavior patterns purely from the AP side, since the AP has only limited information. More specifically, estimating the parameters of an activity (behavior) model is an ill-conditioned problem because an AP observes. Predicting future activity from such observations is difficult. The AP also may not be able to observe complete information about the activity patterns. For example, the AP may not know about all previous failed access attempts (since device activity algorithms cannot deduce when an access attempt was unsuccessful).
  • a drawback with uplink configured grants includes that it is the RRC on the network side that determines all parameters of the configured grant, while it is the UE that has the best knowledge of the current traffic.
  • the set of configuration parameters in a configured grant may quickly become ill suited for the needs of the UE.
  • a configured uplink grant is still a form of traffic scheduling, and while it may lack some drawbacks that come with dynamic scheduling in terms of signaling overhead, a configured uplink grant also has very little flexibility in comparison to dynamic scheduling. [0058] As previously indicated, there is a need for improved grant-free random access of a communication device to a communication network that may improve overhead (or enable low overhead) while having a large degree of flexibility to efficiently support use cases with varying traffic behavior.
  • Potential advantages that may be provided by one or more embodiments may include improving grant-free random access of a communication device to a communication network by including an uplink signal by which a communication device sends an estimate of transmission activity of the communication device for a future time period (in other words, statistical predictions on how likely the communication device is to transmit at given points in the future).
  • these predictions may also contain information about additional statistics related to transmissions, e.g., packet size distribution, priority class, latency requirements, error tolerance, etc. (referred to herein as "side information").
  • a vast amount of data that the communication device has access to (e.g., video streams, sensor data, battery status, or other information) and that would nominally be infeasible to convey to a network node, (e.g., an AP) is condensed into a message that provides a network node (e.g., an AP) with side information about the communication device's future behavior which in turn can aid device activity detection.
  • a network node e.g., an AP
  • improvement to overhead while having a large degree of flexibility to efficiently support use cases with varying traffic behavior may be accomplished.
  • Performance also may be improved in device activity detection in grant-free random access, e.g., probability of detection versus probability of false alarm. Such improvement, in turn, may lead to improved overall throughput, lower latency, and higher relatability. Further, knowledge related to future traffic also may provide more time for the network to adapt its operational states, e.g., to activate more resources (frequency bands, base stations, antenna elements, RAN compute capacity, etc.) before an actual overload situation occurs. Thus, more robust network performance and a better user experience may be achieved.
  • Various embodiments of the present disclosure include a system with at least one network node and at least one communication device.
  • the communication device determines an estimate of its future activity, and transmits information related to the estimated future activity to the network node.
  • the network node can use the information about the estimated future activity of the communication device as side information in device activity detection.
  • Some embodiments further include the communication device obtaining data from a sensor, and determining an estimate of future activity of the communication device based on the data from the sensor.
  • the communication device transmits to the network node information related to the estimated future activity.
  • the estimated future activity can be in the form of: a set of quantized coefficients (e.g., ⁇ ai ⁇ ⁇ ); future access probabilities ⁇ p t ⁇ ; a set of parameters describing future access probabilities (e.g., (l, m, s )); an indicator (e.g., traffic prediction indicator (TPI)).
  • Some embodiments further include the network node, based on the information transmitted from the communication device, determining an estimate of future access probabilities ⁇ p t ⁇ ; and the communication device performing data reduction (which can include compression) of ⁇ p t ⁇ and obtaining a set of coefficients ⁇ a k ⁇ .
  • the parameters ⁇ a k ⁇ are obtained by fitting a family of pre-determined basis functions ⁇ pf ⁇ .
  • each communication device observes sensor data (which could be massive, and typically large enough that it cannot feasibly be sent in its entirety to the network node).
  • sensor data include, but are not limited to, video streams from a camera, audio signals, light, temperature and vibration observations, air pressure sensors, humidity sensors, etc.
  • Data can also be derived from observations of the behavior of humans and other agents (e.g., from an accelerometer of the communication device). Services, higher layer functions, applications, etc. that are currently running locally on the UE may not be fully known to the radio access network (RAN), but the UE can use such information to derive statistical information related to future transmissions.
