Abstract: A multi-band communication device includes: one or more transceiver circuitries, each of which in operation transmits and receives data on a plurality of channels in different frequency bands; and a band configuration circuitry operative to change a configuration of any one of the transceiver circuitries based on configuration information received from a multi-band Access Point (AP). The configuration information specifies one of the frequency bands as a Primary band and the other frequency bands as Secondary band(s). The transceiver circuitry operating on the Primary band is used as a default circuitry for communication with the AP.

Abstract: The present disclosure provides communication apparatus and communication method for PPDU format identification. The communication apparatus comprising circuitry which, in operation, generates a Physical Layer Protocol Data Unit (PPDU) that contains a first signal field, a second signal field and a third signal field, and wherein the second signal field is used to determine whether a physical layer (PHY) version of the generated PPDU is not older than a defined PHY version, and the third signal field is used to indicate the PHY version of the generated PPDU; and a transmitter which, in operation, transmits the generated PPDU.

Abstract: According to aspects of the present disclosure, communication apparatus and methods are provided. According to one aspect, a communication apparatus operating in at least a first band and a second band, the communication apparatus may comprise a receiver which, in operation, receives a signal including a Trigger frame allocating at least one Random Access Resource Unit (RA-RU) and a controller. In operation the controller may set a first Orthogonal Frequency Division Multiple Access (OFDMA) random access backoff (OBO) counter according to a number of RA-RUs determined to be eligible in at least one of the first and second bands in the received Trigger frame; and randomly select an eligible RA-RU in each of the at least one of the first and second bands corresponding to the first OBO counter for Trigger Based (TB) Physical layer Protocol Data Unit (PPDU) transmission when the first OBO counter is set to 0. The first OBO counter may be initialized according to a first OFDMA Contention Window (OCW).

Abstract: At an access point (AP)(100), a trigger frame generation unit (104) generates a trigger signal ordering transmission of an upstream signal. The trigger signal includes a terminal information field which includes a terminal ID sub-field and a resource unit allocation information sub-field. A wireless transmit/receive unit (106) transmits a trigger signal. The trigger frame generation unit (104), if the trigger signal includes a first terminal information field indicating one or more successive random access resource units, sets in the first terminal information field an unused ID that is not used as a terminal ID.

Abstract: En un punto de acceso (AP) (100), una unidad de generación de cuadro de activador (104) genera una señal activadora que ordena la transmisión de señal de enlace ascendente. La señal activadora incluye un campo de información de terminal que incluye un subcampo ID de terminal y un subcampo de información de distribución de unidad de recurso. Una unidad inalámbrica de transmisión/recepción (106) transmite una señal activadora. La unidad de generación de cuadro de activador (104), si la señal activadora incluye un primer campo de información de terminal que indique una o más unidades sucesivas de recurso de acceso aleatorio, establece en el primer campo de información de terminal un ID no usado que no es usado como un ID de terminal.
