Title: Energy correction in an uplink OFDMA 802.11 channel
Inventor: Stéphane Baron
IPC: H04W72/04
Filed: 2017-10-31
Abstract: A station in a wireless network identifies a resource unit in a multi-user uplink transmission opportunity 340 which has been dedicated to padding data, then transmits on this resource unit to provide energy correction. The station may detect the energy transmitted during the preamble period 350 of the transmission opportunity, and transmit the energy corrective data if this energy falls below a certain threshold. The energy correction resource units may be signalled by the access point in a trigger frame 330, and may be distributed homogenously over the channel with one at the centre of the frequency band. The station may be the access point or a non-access-point station. Where the station is the access point it may comprise two antennae, the first for receiving the uplink transmission and the second for transmitting the corrective data. The scheme is intended for interference reduction in an IEEE 802.11ax WLAN, with the energy correction used to prevent legacy stations making erroneous determinations of an idle channel.

Title: Driver circuit, light-emitting display device, and driving method
Inventor: MINHYUNG KANG
IPC: H01L27/32
Filed: 2019-07-29
Abstract: A diver circuit, a light-emitting display device, and a driving method for a light emitting display device. The method involves, during a sensing period, S610, supplying a sensing voltage and a sensing reference voltage to a target sub-pixel through a data line and reference voltage line respectively. The voltage of the reference voltage line is increased, S620, and a voltage of the reference voltage line detected when a predetermined time, delta t, has passed after the start of the increasing of the reference voltage line voltage. During the increase of the reference voltage line voltage and detection of the reference voltage line voltage a data line overlapping the reference voltage line is maintained at a voltage different from the sensing data voltage. Even in the case that other video control driving e g. fake data insertion driving, is performed during sensing driving, the sensing is not influenced by the other video control driving, e.g. fake data/black data insertion driving.
Patent GB-2573934-A (GB)
Title: Selective sub-carrier processing
Inventor: SUJAI CHARI
IPC: H04L27/26
Filed: 2016-03-31
Abstract: Selective subcarrier processing of a received multicarrier (OFDM) signal comprises determining whether a quality of the signal is better than a predetermined quality, selected to ensure that a probability of error free decoding is greater than a predetermined threshold. This involves determining whether the signal was received through a line-of-sight (LOS) channel or a non-line-of-sight (NLOS) channel. An approximate required signal to noise ratio (SNR) is selected based on the LOS/NLOS determination and the SNR of the signal during a preamble is compared with this. If the quality of the signal is better, a determination is then made as to which subcarriers to perform signal processing on based on a relative signal quality of each subcarrier. By not processing all subcarriers, power consumption is reduced. The subcarrier selection may involve the use of log likelihood ratios (LLRs) and a parity check matrix based on LDPC (low-density parity check) encoding. Selection may be based on the orthogonality of a channel matrix of each subcarrier. The power consumed per processed subcarrier and a probability of decoding error may be used. MAC layer information obtained from previous packets may be used. The percentage of subcarriers selected may be based on the coding rate.
