Abstract: Preventing peak current draw in a wireless device. In an embodiment, a data payload to be transmitted is segmented into data payload segment(s) based on the data payload size and a peak current rating of the wireless device's battery, such that each data payload segment has a segment size which is estimated to result, during transmission of the data payload segment, in a maximum current draw from the battery that is less than the peak current rating of the battery. Then, each data payload segment is transmitted, such that the transmission of one data payload segment does not overlap with the transmission of any other data payload segment.

Abstract: Extended sleep in a wireless device. In an embodiment, synchronized parameters, used by a wireless device to define an extended-sleep cycle, are stored at a system. Based on the synchronized parameters, the system determines a transmission time at which to transmit a message over the wireless communication network such that the message will be received by the wireless device during a portion of the extended-sleep cycle during which the wireless device is monitoring paging occasions. The message is then queued until it is transmitted at the transmission time.

Abstract: Systems and methods for uplink (UL) and downlink (DL) communications can improve channel capacity between one or more access nodes and one or more terminal nodes. The communications may utilize, for example, multi-user multiple-input multiple-output techniques with cooperation between access nodes. A network node may determine an ordering combination and associated pre-weighting values, provide the pre-weighting values to one or more terminal nodes, receive signals transmitted from the terminal nodes using the pre-weighting values; and process the received signals using the ordering combination and the pre-weighting values. Two constraints can be jointly used: a minimum performance constraint and a maximum transmit power constraint. Example systems search all possible ordering combinations to find a best combination, for example, the ordering combination that maximizes communication rates.

Abstract: Systems and method for adaptive constellation mapping determine transmission formats for simultaneous transmission from multiple transmitter chains. The adaptive constellation mapping can select a winning combination of mappings using distance metrics. The distance metrics can be calculated from estimated received signal constellations at a multi-layer receiver. The multi-layer receiver can separate the data received from each of the transmitter chains. Additional systems and method can determine a whether to use adaptive constellation mapping or an alternate transmission format. Further systems and methods can determine a transmit arrangement that include selection of which of multiple transmitters will be a part of an adaptive constellation mapping transmission, the number of layers that will be transmitted by each transmitter, the transmitter chains that will be used, and which of multiple antennas that will be used.

Abstract: An access node in a wireless communication network receives a transmission that includes first and second signals. The first and second signals may be layers of a multiple-input multiple-output transmission and may also be from first and second terminal nodes. The access node derives first and second local reference signals from the transmission received using first and second antennas and estimates channel transfer functions associated with the channel through with the transmission is received. Estimating the channel transfer function can include correlating at least a portion of an expected reference signal associated with the first signal with a corresponding portion of the first local reference signal and correlating at least a portion of an expected reference signal associated with the second signal with a corresponding portion of the second local reference signal. The expected reference signal portions used to estimate the channel transfer functions may be non-orthogonal.
