Text: sion bandwidth in a point-to-multipoint commu- nication system, where a customer premises equipment (CPE) is communicating with a base station controller (BSC) over a link shared with other CPEs, comprising the steps of: operating the CPE in a grant pending state wherein the CPE awaits receipt of a band- width grant from the BSC, receives the bandwidth grant, transmits data to the BSC using the granted bandwidth, trans- mits further bandwidth requests using the granted bandwidth and transitioning from the grant pending state to a grant pending absent state once the CPE has transmitted upstream data to the BSC within a band- width specified by the bandwidth grant re- ceived from the BSC during the grant Case: 21-2112 Document: 37 Page: 5 Filed: 07/19/2022 WIRELESS PROTOCOL INNOVATIONS, INC. v. TCT MOBILE, INC. 5 pending state and the CPE has no pending bandwidth requests; operating the CPE in the grant pending ab- sent state awaiting arrival of data for transmission to the BSC and transmitting a first type bandwidth request to the BSC without entering into contention when the CPE receives data for transmission; transitioning operation of the CPE from the grant pending absent state to the grant pending state after a subsequent band- width grant is received at the CPE; and transitioning operation of the CPE from the grant pending absent state to an idle state if the CPE does not transmit any first type bandwidth request to the BSC during a timeout period. Claims 3–5 directly or indirectly depend on claim 1 and WPI does not make any separate patentability arguments regarding those claims.
