摘要:
An embodiment of a system for the coexistence of a wireless local area network (WLAN) in power saving mode, and another type of wireless transmission is provided. A wireless transmission module is configured to transmit or receive data in two slots separated by an available window. A WLAN module is configured to obtain information regarding the available window and transmits a polling request (PS-Poll) at a supported rate higher than any basic rate in the available window in order to obtain buffered data from an access point (AP). The supported rate is encoded in a supported rate set while the basic rate is encoded in a basic rate set announced by the AP.

A wireless communications system is provided with a first wireless communications and a second wireless communications. The first wireless communications module transmits or receives a first wireless signal in a first frequency band selected from a first frequency range. The second wireless communications module transmits or receives a second wireless signal in a second frequency band selected from a second frequency range, and adjusts a transmission power of the second wireless signal in response to that a frequency offset between the first frequency band and the second frequency band falls within a predetermined range.

A method and apparatus for traffic arbitration in a system are provided. In the system, a first module operating in a first protocol and a second module operating in a second protocol share one communication channel. An arbitration circuit schedules medium accesses thereof, in which a quota table maintains a utilization value updated in accordance with the amount of time slots consumed by a particular traffic type, and a time counter periodically resets the utilization value to a default value. When the arbitration circuit receives a request for medium access of the particular traffic type, the arbitration circuit grants the request according to the utilization value, such that the first module or the second module are not activated at the same time.

A wireless communications system is provided with a first wireless communications module, a second wireless communications module, and an RF module. The first wireless communications module transmits or receives a first wireless signal, and the second wireless communications module transmits or receives a second wireless signal. The RF module allocates a first transceiving path and a second transceiving path to the first wireless communications module and the second wireless communications module, respectively, to enable the transmission or reception of the first wireless signal and the second wireless signal at the same time.

An embodiment of a system for the coexistence of a wireless local area network (WLAN) and another type of wireless transmission is provided. A WLAN module in a power saving mode is configured to transmit a polling request (PS-Poll) at a supported rate higher than any basic rate in order to obtain buffered data from an access point (AP) when the coexisting wireless transmission module is operating. The supported rate is encoded in a supported rate set announced by the AP, and the basic rate is encoded in a basic rate set announced by the AP, and the PS-Poll is a polling request relating to a power saving mode of operation.
摘要:
A station connecting to an access point of a wireless local area network (WLAN) is disclosed. A radio frequency (RF) module demodulates received radio signals into baseband signals. A baseband module, coupled to the RF module, converts the baseband signals to a bit stream. A media access control (MAC) module, coupled to the baseband module, processes the bit stream to obtain data packets. An application specific integrated circuit (ASIC), coupled to the baseband module, and MAC module, causes the station to enter a sleep mode, wakes up at least one of the components of the station at a preset original wake-up time to receive a beacon frame from the access point, parses the beacon frame to extract traffic indication map (TIM) information specified therein, and determines a next wake-up time by adjusting the original wake-up time according to the TIM information.

A communications apparatus is provided. A first radio module provides a first wireless communications service and communicates with a first communications device in compliance with a first protocol. A second radio module provides a second wireless communications service and communicates with a second communications device in compliance with a second protocol. A Co-Located Coexistence radio manager detects activities of the first radio modules, obtains a first traffic pattern describing downlink and/or uplink traffic allocations of the first radio module from the first radio module, and generates a second traffic pattern of the second radio module according to the first traffic pattern to coordinate operations of the first and second radio modules. The second traffic pattern describes recommended downlink and/or uplink traffic allocations to a plurality of sub-frames for the second radio module, and each sub-frame defined by the second protocol includes Orthogonal Frequency Division Multiplexing symbols.
