Abstract: Various embodiments are described to address the need for a method and apparatus that could reduce the start-up delay for uplink data transfers in multiple-access technologies. A time-symbol threshold (551) is introduced for an uplink frame (550) in order to create a partition of the frame that includes the earlier of the available time symbols and in which any bandwidth request allocations may be placed. By placing bandwidth request allocations earlier in the uplink frame (i.e., at or before the time-symbol threshold), remote units are able to send their bandwidth requests to a scheduler sooner and thereby receive a bandwidth grant for an uplink data transfer with less delay.

Abstract: An arrangement for providing synchronization between a number of overlapping area access points within a wireless LAN utilizes a Power over Ethernet (PoE) cable connection to transmit synchronization signals from a centralized hub/switch to each of the access points connected to the cable. The synchronization signal takes the form of a direct sequence spread spectrum (DS-SS) signal that is coupled onto the twisted pair used to provide the low voltage PoE signal to various powered devices. At each access point, a filter is used to remove the synchronization signal from the PoE transport, allowing for the group of access points to share a common beacon signal and allow for frequency re-use among the access points. The DS-SS signal is preferable created by a combination of a baseband signal and a set of separate pseudo noise (PN) sequences defining a precision phase (“pilot tone”) signal, a time mark (superframe/beacon) signal, and a time-of-day (real-time clock) signal.

Abstract: A base station receives loading information indicative of the loading of other base stations and determines a downlink transmission power budget as a function of the received loading factor information. The base station may decrease/increase a current power budget dedicated to downlink traffic channel segments in response to detecting an increase/decrease in loading at an adjacent base station.

A base station can consider possible alternative transmission power levels, estimated levels of interference, and/or possible alternative data rates in making trade-off decisions regarding downlink power budget.
