  • Patent number: 11533777
    Abstract: In modern networks, RRU and BBU equipment of an access point site typically handles traffic from a single sector. An RRU-BBU pair process that traffic (often limited to a single spectrum from a single sector) according to implemented capabilities and other equipment located further upstream perform functions that rely on information from multiple sectors. An integrated device (e.g., white box) can integrate the functionality of multiple RRU (or NR in 5G) and the functionality of multiple BBU (or DU/CU splits in 5G), which can reduce implementation footprint, costs, and can provide related services more efficiently without going upstream.

  • Patent number: 11464031
    Abstract: Techniques include retrieving from storage a plurality of policies for sharing a shared channel among nodes in a data communications network. The plurality of polices define a tree of periodic schedules of variable periods, each policy defines a transmit time slot as a unique slot i of a modulus of a power m of a base b of a series of time slots, where m indicates a level of the tree of periodic schedules. The method also includes; observing at a first node the probabilities of empty time slots, successful time slots, and collision time slots on the shared channel; selecting at the first node a first policy among the plurality of policies based on the probabilities observed instead of a message received from a central authority; and transmitting a local data packet from the first node onto the shared channel at a transmit time based on the first policy.

  • Patent number: 11452102
    Abstract: The various embodiments provide methods implemented in a multi-RF communication device for managing a victim subscription's de-sense by proactively implementing an RF coexistence management strategy on the victim subscription when an RF coexistence event starts. In various embodiments, a multi-RF communication device may implement an RF coexistence management strategy by determining when an aggressor subscription will de-sense a victim subscription and configuring the victim to anticipate and mitigate de-sense during the aggressor's transmissions. Thus, the various embodiments may provide dramatic improvements to the victim's overall reception performance and overall user experience.

  • Patent number: 11317444
    Abstract: Aspects of the present disclosure provide for random access channel (RACH) configuration in wireless communication systems. In some examples, a RACH configuration may be selected for use by a scheduled entity in transmitting a RACH signal to a scheduling entity based on an estimated timing advance value. The RACH configuration may include, for example, a transmission time of the RACH signal and/or a RACH waveform configuration identifying at least a cyclic prefix (CP) length and a guard time (GT) for the RACH signal. In some examples, the CP and GT length may each be set to the difference between an estimated maximum round-trip time (RTT) and an estimated minimum RTT between the scheduled entity and the scheduling entity. In some examples, the timing advance value may be estimated as the estimated minimum RTT.
