Abstract:
Embodiments of the present application provide a decoding method and a decoding device. The decoding device receives a second code word, which is transmitted from an encoding device based on a first code word. The first code word is generated by the encoding device based on a first encoded data sequence. After determining that a second encoded data sequence based on the second code word is not a correct replica of the first encoded data sequence, the decoding device performs a series of code element update processes to determining the correct replica of the first encoded data sequence.
Abstract:
A precoding matrix indicator (PMI) is determined for a user equipment or a base station, where the PMI corresponds to a precoding matrix W, and the precoding matrix W satisfies a first condition, a second condition, or a third condition; and the PMI is sent to a base station. The precoding matrix indicator can effectively control a beam, especially a beam shape and a beam orientation, in a horizontal direction and a perpendicular direction.

Abstract:
The present disclosure provides, for example, methods for measuring interference to a cable modem (CM), and corresponding example apparatuses and systems. One example method includes sending, by a cable modem termination system (CMTS), a broadcast message to all CMs connected to the CMTS, where the broadcast message includes information designating one of the CMs to send a probing signal by using a spectrum S in a timeslot T. The CMTS can then broadcast a pseudo random binary sequence (PRBS) by using the spectrum S in a downlink direction in the timeslot T, and can obtaining modulation error ratio (MER) information recorded in the timeslot T by other CMs. A difference between MER information in the timeslot T and MER information in a normal data timeslot can be used, for each of the other CMs, as intensity of interference to the corresponding CM.
