In 3GPP LTE Release-11 the Enhanced Physical Downlink Control Channel (EPDCCH) has been specified for downlink and uplink radio resource assignment notifications to User Equipments (UEs). EPDCCH has been designed to overcome several limitations of the Physical Downlink Control Channel (PDCCH) used in LTE Release 8–10. Some of the important design objectives of EPDCCH are: increased capacity for DL...
This paper investigates the impact of multiple BER requirements on resource allocation for orthogonal frequency division multiple access (OFDMA) downlink systems. Max-total capacity (MTC) and proportional fairness (PF) problems are considered. With the goal of maximizing either the instantaneous or long-term network capacity, we propose BER-driven resource allocation (BRA) schemes which exploit both...
Public WLANs based on IEEE802.11 standard are now widely deployed. In an environment offering several APs (Access Points), a UTE (User Terminal Equipment) needs to choose which AP to associate with. Conventionally, the UTE associates with the AP with the strongest RSSI (Received Signal Strength Indicator). This simple approach, however, can degrade the efficiency of network utilization since the UTE...
