  • Patent number: 10397914
    Abstract: Methods and systems for wireless communication are disclosed. In one aspect, a method includes generating device specific transmission control information for each of two devices, transmitting the transmission control information for each device over different frequencies, and transmitting data to each of the devices as part of a communication according to the respective transmission control information. In some aspects, the transmission control information for each device is encoded based on an identifier of the device. For example, in some aspects, an error detection value such as a cyclic redundancy check, is exclusive or'ed with an identifier of the device, such as an AID, PAID, or group identifier. The resulting value is transmitted along with the transmission control information. A device receiving the wireless frame may only be able to decode its own transmission control information, as the decoding is also based on the receiving device's identifier.

  • Patent number: 10165551
    Abstract: A device may signal a resource allocation scheme in a high efficiency wireless local area network (WLAN) preamble. In one example, a high efficiency (HE) WLAN signaling field is used to signal a resource allocation pattern to multiple devices. The HE WLAN signaling field includes a common user field that is decodable by the multiple devices and includes a resource allocation field. The resource allocation indicates resource unit distributions to the multiple devices and indicates which resource units in a multi-user PPDU correspond to multi-user MIMO transmissions and which resource units correspond to OFDMA single-user transmissions. The HE WLAN signaling field also includes dedicated user fields that are assigned to certain devices. The order of the dedicated user fields corresponds to the allocated resource units. The HE WLAN signaling field is transmitted with a WLAN preamble to the multiple devices.

  • Patent number: 10136358
    Abstract: A wireless device may selectively add padding to an end of a data transmission in order to provide adequate time for a receiving device to process the transmitted data and transmit feedback related to the transmitted data. A wireless device may identify a total amount of data capable of being transmitted in a transmission, and determine a number of data bits to be transmitted in the transmission. An amount of padding may be selected based on a proportion of the total amount of data capable of being transmitted and the number of data bits. In some examples, a preamble for a feedback transmission may be transmitted concurrently with processing of the received transmission.
