Abstract: A wireless communication method comprises the following steps: a Static and Public Virtual Access Point (PS-VAP) on a Physical Access Point (PAP) receives a Probe Request from a station; the PS-VAP sends a Virtual Access Point (VAP) Setup Request to a server in response to the Probe Request; the PAP creates a Dedicated-and-Dynamic VAP (DD-VAP) having a Service Set Identifier (SSID) for the station according to a VAP Setup Response sent from the server; and the DD-VAP sends a Probe Reply including the SSID of the DD-VAP to the station.

Abstract: Methods and apparatuses of mitigating interference in a heterogeneous network using an inter-cell interference coordination are provided. An interference control server assigns, for each of the UE groups, a set of almost blank subframes (ABS) or non-preferred sub-bands specific to the corresponding one of the UE groups based on the UE group interference relationship and a resource demand for each of the UE groups. A base station assigns a plurality of sets of ABS (or non-preferred sub-bands) to reuse time-domain (or frequency-domain) resources.

Abstract: A hybrid automatic repeat request method comprises selecting a first HARQ process group from HARQ process groups to send a first data packet, recognizing that a feedback signal corresponds to a first HARQ process in the first HARQ process group according to the feedback signal and the time of receiving the feedback signal, determining whether the last used HARQ process in the first HARQ process group is identical to the first HARQ process when the first data packet is decoded incorrectly, instructing the first HARQ process to transmit the first data packet when the two processes are different, and instructing the first HARQ process to transmit a second data packet or the first data packet when the two processes are identical, wherein the first data packet is based on a whole of the raw data, and the second data packet is based on a part of the raw data.

Abstract: A method for scheduling radio resource in an unlicensed spectrum and a base station using the method is provided. This method includes following steps. Downlink data are obtained, and the first starting time point for a downlink transmission of this downlink data is estimated. A plurality of second starting times are set according to the first starting time point.

Each of the DCIs is corresponding to each of the first start time point or the second start time points, and each of the DCIs points to a radio resource block of the downlink data. Clear Channel Assessment (CCA) procedure in the unlicensed spectrum is performed, and the DCIs are disposed in a physical downlink control channel (PDCCH) after the channel process is completed.
