An improved sieve bed design to manage breakthrough and the mass transfer zone by way of volumetric division. An empty space in the product end is separated from adsorbent-filled sieve space in the feed end by a mid-diffuser plate.

Systems and methodologies are described that facilitate scheduling uplink transmissions. For instance, a time sharing scheme can be utilized such that differing mobile devices can be scheduled to transmit during differing time slots; however, it is also contemplated that a static scheme can be employed. Pursuant to an illustration, an interference budget can be combined with a time varying weighting factor associated with a base station; the weighting factor can be predefined and / or adaptively adjusted (e.g., based upon a load balancing mechanism).

Further, disparate interference budgets can be utilized by differing channels of a sector at a particular time. Also, for example, a base station can assign a loading factor to be utilized by wireless terminal(s) for generating channel quality report(s).

Methods and apparatus are described where loading information regarding loading conditions at a neighboring base station is received at a first base station and then communicated, e.g., broadcast, by the first base station to mobiles within the cell in which the first base station is located. Since the neighbor base station's loading information is being communicated to a mobile currently connected to the first base station via a reliable communications channel of the first base station, the mobile can be expected to be able to reliably recover loading factor information corresponding to not only the first base station but to the neighboring base station. By utilizing such loading factor information, the mobile can generate an improved uplink interference report. The first base station receives such interference reports from wireless terminals in its cell, facilitating efficient resource allocation and interference control.
