20190312667 | IMPULSE NOISE MANAGEMENT - A discrete multitone transceiver (DMT) includes a deinterleaver operable to de-interleave a plurality of bits. The DMT further includes: a forward error correction decoder operable to decode the plurality of bits, a module operable to determine, during Showtime, an impulse noise protection value, wherein the impulse protection value specifies a number corrupted DMT symbols that can be corrected by the forward error correction decoder in combination with the deinterleaver, and a receiver coupled to the deinterleaver. The receiver receives using a first interleaver parameter value, receives a flag signal, and changes to receiving using a second interleaver parameter value that is different than the first interleaver parameter value, wherein the second interleaver parameter value is used for reception on a pre-defined forward error correction codeword boundary following reception of the flag signal. | 2019-10-10 |
20190312668 | METHOD FOR RECEIVING REFERENCE SIGNAL RESOURCES IN A WIRELESS COMMUNICATION SYSTEM AND APPARATUS - A method for receiving a Channel State Information (CSI)-Reference Signal (RS) resource in a wireless communication system, the method performed by a User Equipment (UE) may include: receiving, from a base station, a configuration for a CSI-RS resource set including a plurality of CSI-RS resources; receiving the plurality of CSI-RS resources; and when a transmission via different transmission beams of the plurality of CSI-RS resources is configured, reporting a CSI-RS Resource Indicator (CRI) for the plurality of CSI-RS resources to the base station, when a transmission via a same transmission beam of the plurality of CSI-RS resources is configured, not reporting the CRI for the plurality of CSI-RS resources to the base station. | 2019-10-10 |
20190312669 | METHOD FOR TRANSMITTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR - The present invention provides a method for transmitting channel state information in a wireless communication system, and an apparatus therefor. Specifically, a method for transmitting, by a terminal, channel state information (CSI) in a wireless communication system supporting a short transmission time interval (TTI) may comprise the steps of: transmitting first CSI associated with a downlink channel received from a base station, to the base station in a first TTI; and transmitting second CSI associated with the received downlink channel, to the base station in a second TTI, wherein the first CSI includes information indicating a specific region including one or more indices associated with the CSI, and the second CSI includes information indicating a specific index which corresponds to a channel state associated with the received downlink channel among the one or more indices. | 2019-10-10 |
20190312670 | APERIODIC CHANNEL QUALITY INDICATOR REPORT IN CARRIER AGGREGATION - Techniques for reporting channel quality information (CQI) in a multi-carrier wireless communication system are disclosed. In one aspect, a user equipment determines one or more reporting groups, each comprising a plurality of component carriers which are configured for the user equipment. The user equipment may detect a trigger from a base station that selects a reporting group and may respond to the trigger by sending CQI for at least the activated component carriers in the selected reporting group. | 2019-10-10 |
20190312671 | CROSS-CORRELATION REDUCTION FOR CONTROL SIGNALS - Methods, systems, and devices for wireless communications are described. In accordance with the described techniques, communicating devices (e.g., an encoder and decoder) may apply an orthogonal cover code to a polar codeword to reduce cross-correlation between different codewords. For example, such techniques may reduce power consumption at a decoding device by providing for earlier decoding termination (e.g., as a result of the reduced cross-correlation). Techniques for generating the cover codes (e.g., on a per-aggregation level basis) and applying the cover codes (e.g., within a search space) are described. Additionally or alternatively, the described techniques may relate to seeding of reference signals used to support decoding of the codewords. Improved orthogonality between reference signal seeds may further suppress codeword recipient ambiguity. | 2019-10-10 |
