This paper investigates the uplink throughput performance and the interference power to other cells using an Evolved UTRA (E-UTRA) laboratory and field experimental system. In E-UTRA uplink, the near-far problem is not an issue since the orthgonality

This paper proposes a unified packet scheduling method that considers the delay requirement of each traffic data packet whether real time (RT) or non-real time (NRT), the channel conditions of each accessing user, and the packet type in hybrid automa

This paper proposes cell (sector) selection based on shadowing variation for forward-link orthogonal frequency and code division multiplexing (OFCDM) packet wireless access. We clarify its effects using a broadband propagation channel model in a comp
