Abstract: Abstract In an AP (100), a Trigger frame generator (104) generates a trigger signal instructing an uplink signal transmission, the trigger signal including a terminal information field that includes a terminal ID subfield and a resource unit allocation information subfield, and a radio transmitter/receiver (106) transmits the trigger signal. In a case where the trigger signal includes a first terminal information field specifying one or more contiguous resource units for random access, the Trigger frame generator (104) sets an unused ID that is not to be used as a terminal ID in the first terminal information field.

Abstract: Communication devices and methods for multi-link secured retransmissions are provided. One exemplary embodiment provides a multi-link device (MLD) configured to operate with a first plurality of affiliated STAs, comprising: circuitry, which in operation, sets up a robust security network association (RSNA) with a second MLD that is configured to operate with a second plurality of affiliated STAs, wherein two or more links have been established between STAs of the first plurality of affiliated STAs and corresponding STAs of the second plurality of affiliated STAs, wherein the circuitry constructs an Additional Authentication Data (AAD) and a Nonce that are used for cryptographical encapsulation of a MAC protocol data unit (MPDU) to form an encapsulated MPDU, wherein the AAD includes an Address 1 (A1) field, an Address 2 (A2) field, an Address 3 (A3) field and a Sequence Control (SC) field, and the Nonce includes an Address 2 (A2) field, wherein the SC field of the AAD is based on a SC field of the MPDU, and a transmitter, which in operation, transmits the encapsulated MPDU to the second MLD on a first link as an initial transmission, and upon failure of the initial transmission, retransmits the encapsulated MPDU on a second link without reperforming the cryptographical encapsulation.

Abstract: The present disclosure provides communication apparatus and communication method for user-specific persistent allocation. A communication apparatus comprises circuitry which, in operation, generates a transmission signal comprising a common field, a user specific field and a data field, the common field including RU information for each of one or more allocations in the data field and the user specific field including one or more user information, each indicating a user-specific allocation among the one or more allocations in the data field; and a transmitter, which, in operation, transmits the generated transmission signal; wherein the user specific field is free from at least one user information for a persistent allocation containing a recurring transmission among the one or more allocations.

Abstract: The present disclosure provides communication apparatus and communication method for channel estimation. The communication apparatus comprises a transmitter, which in operation, transmits a physical layer protocol data unit (PPDU) to one or more other communication apparatus in a multiple-input multiple-output (MIMO) wireless network, the PPDU including a long training field (LTF) that facilitates the one or more other communication apparatus to estimate respective channels for respective communications with the communication apparatus; and a controller, which in operation, establishes the number of LTF symbols (NLTF) for generating the LTF in the PPDU, wherein the NLTF depends on a maximum value (NSTSMAX) of the number of space-time streams for each resource unit (RU) in the PPDU.

Abstract: El primer aspecto de la solicitud es dirigido a un aparato de comunicación de múltiples bandas que incluye un transmisor y un receptor. El transmisor que en operación transmite, en una red inalámbrica y a los dispositivos de comunicación de múltiples bandas, cuadros en una banda de frecuencia que incluyen acciones relacionadas con la banda de frecuencia y con al menos otra banda de frecuencia en la cual transmite el aparato de comunicación de múltiples bandas. El receptor que en operación recibe, en la red inalámbrica, de los dispositivos de comunicación de múltiples bandas, cuadros en la banda de frecuencia que incluyen acciones relacionadas con la banda de frecuencia y con al menos la otra banda de frecuencia en la cual recibe el aparato de comunicación de múltiples bandas. El segundo aspecto de la solicitud es dirigido a un AP de múltiples bandas que transmite/recibe cuadros a/de las estaciones sin-AP en una red inalámbrica única que opera al mismo tiempo en múltiples bandas de frecuencia, en las cuales la red inalámbrica única es identificada por un identificador único de conjunto de servicios básicos (BSSID).

Abstract: The present disclosure provides communication apparatus and communication method for enhanced direct link communication. A communication apparatus is configured to communicate wirelessly with an access point (AP) on a first channel, the communication apparatus comprising: circuitry, which, in operation, generates a channel use permission request frame, the channel use permission request frame comprising information indicating the communication apparatus, another communication apparatus and a second channel that is different from the first channel; a transmitter, which, in operation, transmits the generated channel use permission request frame to the AP to seek permission from the AP to use the second channel for direct link communication with the another communication apparatus; and a receiver, which, in operation, receives a channel use permission response frame from the AP permitting use of the second channel, wherein the communication apparatus is further configured to communicate with the another communication apparatus on a direct link in the second channel after receiving the channel use permission response frame.
