Abstract: A method of data transmission over guard sub-carriers is provided in a multi-carrier OFDM system. Adjacent radio frequency (RF) carriers are used to carry radio signals transmitted through adjacent frequency channels. A plurality of guard sub-carriers between adjacent frequency channels are aligned and identified for data transmission in a pre-defined physical resource unit. The identified guard sub-carriers do not overlap with normal data sub-carriers of the radio signals transmitted through the adjacent frequency channels. At least one of the identified guard sub-carriers is reserved as NULL sub-carrier. A flexible multi-carrier transceiver architecture is also provided in a multi-carrier OFDM system. Different multi-carrier and/or MIMO/SISO data transmission schemes are implemented by adaptively reconfigure same hardware modules including common MAC layer module, physical layer entities, and RF entities. Furthermore, the flexible multi-carrier transceiver architecture can be used to support data transmission over guard sub-carriers.

Abstract: A wireless communication system includes an access point and at least one station. The access point sends a trigger frame including power information for indicating a targeted receive power of data sent from the at least one station to the access point and an output power of the target frame. Each of the at least one station sends data to the access point by referring to the targeted power.

Abstract: Various schemes pertaining to coordinated time-division multiple-access (C-TDMA) protocols, transmission opportunity (TXOP) sharing modes for time allocation, and exchange of parameters in multi-access point (multi-AP) systems are described. An apparatus (e.g., a sharing access point (AP)) acquires a TXOP. The apparatus also triggers one or more shared APs to participate in C-TDMA communications with respectively associated stations (STAs) within the TXOP.

Abstract: Systems and methods of transmitting and receiving a Wake-Up Radio (WUR) packet by using a simplified preamble structure that contains no training field. The preamble carries a signature sequence selected from a set of predefined sequences, each corresponding to a different data transmission rate. The preamble and the control information of the WUR packet are transmitted in the same rate as indicated by the selected sequence. Hence, a receiving WUR can determine the data transmission rate and locate the associated control information directly if a sequence that matches a predefined signature sequence is detected. The same sequence or in combination with an additional sequence in the preamble may also be used to indicate automatic gain control synchronization, packet type and other related information.

Abstract: A wireless communication method includes setting at least one specific subfield of a control field in a report frame, and transmitting the report frame to an access point for communicating with the access point on uplink (UL) Orthogonal Frequency-Division Multiple Access (OFDMA). In addition, the wireless communication method is performed by a program code loaded from a storage device of a wireless communication device and executed by a processor of the wireless communication device.
