Title: Coupled uplink/downlink power control and spatial processing with adaptive antenna arrays
Patent number / application: US7003310B1 (application US09/967,857)
Inventors: Mike Youssefmir; Mitchell D. Trott
Original assignee: Arraycomm LLC (recorded as Arraycomm, Inc. at filing; later listed as Intel Corp as current assignee per the source's own disclaimer that listed assignees may be inaccurate)
Key dates: Priority/filing date 2001-09-28; granted/publication date 2006-02-21; "Adjusted expiration" 2023-06-14; status listed as "Expired - Fee Related"
Purpose (plain language): The patent relates to wireless communication systems—cellular systems and wireless local loop systems—using adaptive antenna arrays at base stations. Antenna arrays provide improved signal-to-noise ratio and interference rejection on receive, and improved directionality with less power toward co-channel users on transmit. The disclosed subject matter couples power control with spatial processing: a base station creates different transmit and receive patterns in real time, using spatial processing (a linear spatial processing algorithm in the described embodiment) to process received uplink signals and generate downlink array patterns.
Scope as described: An adaptive antenna array with multiple antenna elements and an antenna array controller; a beamformer controlling amplitude and phase via a weight vector (W) applied through a filter at each element. Received signals are weighted by a receive weight (spatial demultiplexing weight) dependent on the transmitting remote user's receive spatial signature; the reception weight may be modified for array/electronic calibration and used to generate a transmission weight, forming a downlink pattern that delivers power to a desired user and directs nulls toward interference sources. Remote devices may send signal-quality measurements in a report; the base station may reply with a power control message commanding increased or decreased transmit power.

What the supplied excerpt does not establish: The full text of the claims is not included, so the precise legal scope is not established. The excerpt also omits portions of the specification, the detailed power-control operation (FIG. 6), the remote-device operation (FIG. 5), most equations, and any complete description of the coupled power-control algorithm.

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
