    摘要: Example systems, methods, and devices for efficient indication of bandwidth and stream allocation are discussed. In one embodiment, a method for indication of bandwidth allocation in a wireless network can include partitioning, by a network device, a bandwidth of a wireless signal into a plurality of subband units, assigning one or more switch bits between adjacent subband units, and allocating one or more modified subband units to one or more users of the network. In another embodiment, a method for stream allocation can include partitioning, by a network device, a spatial stream of a wireless signal into a plurality of spatial streams, assigning one or more switch bits between adjacent spatial streams, and allocating one or more modified spatial streams to one or more users of the network. Certain methods, apparatus, and systems described herein can be applied to 802.11ax or any other wireless standard.

    摘要: This disclosure describes systems, and methods related to parallel channel training in communication networks. A first computing device comprising one or more processors and one or more transceiver component may receive a first connection request from a second computing device, and a second connection request from a third computing device. The first computing device may determine a first training field associated with the first connection request and a second training field associated with the second request. The first computing device may send the first training field to the second computing device based at least in part on the first connection request and sending in parallel, the second training field to the third computing device based at least in part on the second connection request. The first computing device may establish a first spatial channel stream with the second computing device based at least in part on the first training field and a second spatial channel stream with the third computing device based at least in part on the second training field.

    摘要: Embodiments of a mobile device transmitter and methods for transmitting signals in different signal dimensions are generally disclosed herein. The mobile device transmitter comprises a mapper to map a block of two or more input modulation symbols to different signal dimensions comprising two or more spatial dimensions, and linear transform circuitry to perform a linear transform on the block of mapped input modulation symbols to generate a block of preceded complex-valued output symbols such that each output symbol carries some information of more than one input modulation symbol. The mobile device also comprises transmitter circuitry to generate time-domain signals from the blocks of precoded complex-valued output symbols for each of the spatial dimensions for transmission using the two or more antennas. The precoded complex-valued output symbols are mapped to different signal dimensions comprising at least different frequency dimensions prior to transmission.
