摘要： Technology for user equipment (UE)-specific assigning of demodulation reference signal (DM-RS) sequences to support uplink (UL) coordinated multipoint (CoMP) is disclosed. One method can include a DM-RS sequence assignment device sorting the plurality of UE into a list according to a number of reception point (RP) links for each UE in a CoMP set, and assigning a base DM-RS sequence and a cyclic shift (CS) to a top-ranked UE from the list. The top-ranked UE can have a highest number of RP links. The DM-RS sequence assignment device can repeatedly assign a different CS of the base DM-RS sequence to a plurality of unassigned UE in a same cell as the top-ranked UE, and repeatedly assign the different CS of the base DM-RS sequence to a plurality of unassigned UE in a cooperatively served cell of the top-ranked UE.

摘要： Examples are disclosed for updating a wireless communication channel estimation. In some examples, a packet may be transmitted or received via a communication channel, the packet having one or more pilot signals that may shift between subcarrier frequencies based on a predetermined first variable associated with a first time duration. A second variable associated with a second time duration may be determined by the receiver of the data packet. The second variable may enable a receiver of the data packet to decide how many pilot signals may be used to update an initial channel estimation for the communication channel. Other examples are described and claimed.

摘要： An approach is provided for defining a 1MHz preamble of a packet. The approach involves determining a preamble sequence of a packet, the preamble sequence having a determinable length. The approach also involves causing, at least in part, the preamble sequence to be divided into a predetermined number of blocks. The approach further involves causing, at least in part, a mathematical operation and a summation over the predetermined number of blocks and a corresponding number of received blocks. The approach also involves causing, at least in part, the summation to be maximized to determine the preamble sequence corresponds to one of a first bandwidth or a second bandwidth, the second bandwidth being greater than the first bandwidth, to determine a type of the packet.

摘要： A method to generate truncated Zadoff-Chu sequences is disclosed. A large Zadoff-Chu sequence is generated, based on a maximum transmission bandwidth, then the sequence is truncated based on the actual transmission bandwidth. The Zadoff-Chu sequence is cyclicly extended, as needed, to maintain a quasi-orthogonal characteristic. The result is that there is an increased number of available Zadoff-Chu sequences for distribution in a wireless neighborhood and the rate of interference is reduced.

摘要： Systems, devices and methods for updating link adaptations in multi-carrier modulated signals between an access point (AP) and a wireless local area network (WLAN) station (STA) include (are configured for) periodically transmitting a channel sounding signal from the AP. The STA receives each unsolicited channel sounding signal and evaluates the current channel conditions between the AP and STA. The AP adjusts a rate of transmission of the channel sounding signals in accordance with the channel coherence time so that the channel estimates performed by the STA will be valid within the time varying characteristics of the channel. Depending on the length of the coherence time for network environment, the channel sounding signals may be AP beacons, low overhead signal fragments with no payload, or a combination of both.

摘要： Logic may comprise a single phase tracking implementation for all bandwidths of operation and the logic may adaptively change pre-defined and stored track parameters if the 5 receiving packet is 1 MHz bandwidth. Logic may detect a packet and long training fields before performing a 1 MHz classification. Logic may auto-detect 1 MHz bandwidth transmissions by a property of the long training field sequences. Logic may auto-detect 1 MHz bandwidth transmissions by detecting a Binary Phase Shift Keying (BPSK) modulated first signal field symbol rather than the Quadrature Binary Phase Shift Keying (QBPSK) associated with the 2 10 MHz or greater bandwidth transmissions. Logic may perform an algorithm to determine an estimated phase correction value for a given orthogonal frequency division multiplexing symbol and several embodiments integrate this value with an intercept multiplier that may be 0.2 for 1 MHz transmissions and, e.g., 0.5 for 2 MHz or greater bandwidth communication.

摘要： Some new low power architecture devices may, e.g., be associated with in a new device category in the IEEE 802.11ah Standard for devices with low power architecture. Some new low power architecture devices may only to support a subset of modulation and coding schemes (MCSs). Some new low power architecture devices negotiate the use of the subset of MCSs with an access point. Further new low power architecture devices address power consumption through modifications to the architecture of the new low power device. For instance, many new low power architecture devices remove, modify or bypass portions of the front-end transmitter circuitry and/or the front-end receiver circuitry such as a power amplifier, a low noise amplifier, predistortion circuitry, digital-to-analog and analog-to-digital converter resolutions, and stages of filtering.

摘要： Logic may implement an orthogonal frequency division multiplexing (OFDM) system operating in the one gigahertz and lower frequency bands. Logic may detect new long training sequences that are differentially orthogonal to each other for a first bandwidth mode of operation such as a one megahertz mode as well as differentially orthogonal to half of the long training sequence for a second bandwidth mode of operation such as a two megahertz or greater mode. Logic may implement two or more long training sequences for the first bandwidth mode of operation to transmit information based upon the selection of the particular long training sequence for the transmission. Logic may implement a new acknowledgement packet comprising a short training sequence and a long training sequence without a signal field and without a payload. And logic may implement bandwidth detection logic to classify a transmission based upon orthogonal properties of the long training sequences.
