  • Patent number: 10739841
    Abstract: Bandwidth for information transfers between devices is dynamically changed to accommodate transitions between power modes employed in a system. The bandwidth is changed by selectively enabling and disabling individual control links and data links that carry the information. During a highest bandwidth mode for the system, all of the data and control links are enabled to provide maximum information throughout. During one or more lower bandwidth modes for the system, at least one data link and/or at least one control link is disabled to reduce the power consumption of the devices. At least one data link and at least one control link remain enabled during each low bandwidth mode. For these links, the same signaling rate is used for both bandwidth modes to reduce latency that would otherwise be caused by changing signaling rates. Also, calibration information is generated for disabled links so that these links may be quickly brought back into service.

  • Patent number: 10666394
    Abstract: Wireless transmission paths are utilized efficiently. An information processing device includes a control section. If data destined for the own device is received from another device and if there exists undelivered data in the data, the control section performs control to transmit a retransmission request for the data to the other device. If there exists no undelivered data in the data destined for the own device and received from the other device, the control section performs control not to transmit a confirmation of reception.

  • Patent number: 10651973
    Abstract: An improved method of computer communication and networking with error-correction encoding and transmission using a punctured polar code construction that is based on polar code decomposition is provided. Advantageously, this allows sorting of a reliability sequence to be performed for a reduced-length vector to identify the information bit positions in the reduced-length polar code vector. Polar code decomposition is used to determine a number of information bits allocated to given reduced-length vector (e.g., K0 and K1). The polar code construction is a function of a puncturing pattern. In some embodiments, the puncturing pattern is a shortening pattern.

  • Patent number: 10630428
    Abstract: Techniques are disclosed whereby a signal is transmitted from a wireless network to a wireless device, requesting automatic repeat-request, ARQ, feedback for certain indicated ARQ processes. This asynchronous approach addresses a problem with irregular ARQ feedback for dynamic time-division-duplexing, and also allows for relaxed processing-time constraints in the wireless device. An example method, in a wireless device, comprises receiving (610) from a wireless communication network, in a first transmission-time interval, a request for ARQ feedback, the request indicating one or more ARQ processes. The example method further comprises transmitting (620) to the wireless communication network, in a second transmission-time interval, ARQ feedback information for each of the one or more indicated ARQ processes.

  • Patent number: 10631200
    Abstract: In a wireless communications system, packet error rate may be relatively low (e.g., five percent). Accordingly, receivers may successfully receive a first transmission the majority of the time. However, bandwidth may be used for retransmissions, which may be used relatively infrequently. Because retransmission packets do not necessarily have to be the same as transmission packets, transmission packets may be given more weight than retransmission packets. For example, transmission packets may be encoded with a higher bitrate than retransmission packets. In aspects, a transmitter may send a first transmission packet, including first data encoded with a first bitrate, and send a second transmission packet, including second data encoded with the first bitrate. The transmitter may send a first retransmission packet that includes the first data encoded with a second bitrate and the second data encoded with the second bitrate, and the first bitrate may be higher than the second bitrate.
