摘要:
A method and apparatus for configuring a downlink frame in a communication system. The method and apparatus includes setting up a first region including allocation information of a data burst according to an amount of the data burst to be transmitted in a downlink frame region; estimating a first transmission Protocol Data Unit/Packet Data Unit (PDU) according to scheduling priority; and transmitting the first PDU over a remaining region except for the first region in the downlink frame region. The data burst includes at least one PDU having the same Modulation and Coding Scheme (MCS) level, or is a data burst generated by concatenating PDUs of the same Mobile Station (MS).
摘要:
A method for scheduling data in a communication system having a downlink frame structure including power control regions of a boosting region for boosting power of a data burst, a normal region for keeping power of the data burst, and a deboosting region for deboosting power of the data burst. A downlink resource assignment method is provided for minimizing the number of slots wasted during BS downlink resource assignment, and improving the cell coverage area or cell capacity by boosting power of bursts to be assigned to an edge cell user whose Carrier-to-Interference Noise Ratio (CINR) is less that a first threshold for separating a boosting region from a normal region, and deboosting power of bursts to be assigned to a near cell user whose CINR is greater than a second threshold for separating the normal region from a deboosting region.
摘要:
An apparatus and method are provided for managing sectors in a transmission operation of a base station including a smart antenna system forming directional beams using a plurality of antenna elements. The apparatus and method comprise determining whether a call connected to a mobile station is a voice call or a data call; multiplying a transmission signal to the mobile station by predetermined complex weight vectors selected according to the call type; and forming a transmission beam for a corresponding sector by summing the multiplied values according to the antenna elements.

摘要:
Methods and apparatuses are provided for performing carrier aggregation (CA) using a plurality of almost blank subframe (ABS) patterns in a macro enhanced Node B (eNB) of a wireless communication system connected to a heterogeneous network. An ABS pattern having a different pattern is determined for each component carrier (CC), when two or more carriers are deployed in each of the macro eNB and at least one small cell eNB. A serving cell for each user equipment (UE) is determined for each CC, from among a macro cell and a small cell. CA is performed for data transmission to each UE using the determined ABS pattern, in accordance with each determined serving cell.
