Patent GB-2575116-A (GB)
Title: Synchronisation symbol detector
Inventor: FILIPE CARVALHO
IPC: H04L27/26
Filed: 2018-06-29
Abstract: A synchronisation symbol detector 700 that comprises two correlation modules 702/704 and a comparison module 706. The first correlation module 702 performs correlations between an input signal and a down-converted version of the input signal to generate a first correlation metric. The second correlation module 704 performs correlations between the input signal and an up-converted version of the input signal to generate a second correlation metric. The comparison module compares the first and second correlation metrics and outputs a determination of whether the input signal comprises a synchronisation symbol. The detector may be used to detect a P1 symbol of a DVB-T2 broadcast or similar digital video broadcast. The detector may detect signals with a normal spectrum or an inverted spectrum such as when IQ swapping has occurred. The advantage of the invention is that the comparison module may use a joint metric created from both correlation module outputs to determine whether a valid signal is present. This combined metric reduces the likelihood of false synchronisation detection caused by amplitude spikes etc. which would cause peaks in the first and second correlation metrics to occur simultaneously instead of individually.

Title: Improvements in and relating to dynamic HARQ in a non-terrestrial network
Inventor: SHANGBIN WU
IPC: H04W28/02
Filed: 2019-07-17
Abstract: A method of controlling HARQ operation in user equipment (UE) communicating with a base station (i.e. 5th Generation Node B, gNB) as part of a non-terrestrial network. The gNB signals S20, e.g. by RRC signalling, to the UE details of an expected Spectral Efficiency (SE), the gNB transmits data to the UE, the UE determines S21 a current SE on the basis of receiving the data transmitted by the gNB, the UE compares S22 the current SE to the expected SE and enables or disables HARQ operation in response to the comparison. If the current SE is less than the expected SE, then HARQ operation may be disabled S23. If the current SE is more than the expected SE, then the UE attempts S24 to decode the received data and, if successful S25, the UE enters S26 ACK-optional state and determines if HARQ feedback is provided. The data transmitted from the gNB to the UE may comprise modulation and coding scheme (MCS) data and HARQ information pointer, which includes a reference to a resource from where HARQ related information can be obtained.

Title: Method for efficient re-ranking and classification of ambiguous inputs in deep hierarchy
Inventor: Adi Botea
IPC: G06F16/906
Filed: 2020-07-06
Abstract: Method for classifying records by relevance to nodes of a hierarchical structure representative of a classification scheme for different classification options, such as a taxonomy of objects, comprising: receiving (22) an input record having record content features, and a contextual attribute indicative of a receipt context of the input record; retrieving (24) relational data indicative of nodes of the hierarchical structure associated with the contextual attribute; determining (30) a relevance score for the nodes of the hierarchical structure to classify (52) the input record. The relevance score of each node depends on: a comparison of the record content features relative to the classification option represented by the node; and the retrieved relational data. The relevant score can be the probability of the input record relating to a node. Contextual information comprises: source of the input record; its time or date of generation or receipt; accompanying records and/or their relevance to the nodes. Hierarchical structures comprise: directed acyclic graphs, trees, and/or corresponding forests. Using historical records reduces uncertainty on the relevant scores. Using contextual information, external to records, in addition to internal information on the subject of the record enables more accurate relevance scores.

Abstract: A contactor 20 with input and output terminals 21, 22 coupled by switching contacts 23. Each terminal is connected to a measurement circuit 51, 53, each circuit producing a measurement signal SM1 and SM2. A signal processing circuit 55 receives these signals and provides an output SOUT in dependence on them. SOUT may depend on a difference between the measurement signals or a time gap between the start- and end times of a pulse of the difference, which may be used to estimate contact-wear. The measurement circuits may include: a voltage divider (100, fig.1B) coupling the contactor terminals to a reference potential; a filter (108, fig.1B); a protection circuit (120, fig.1B); and an analog-to-digital convertor (115, fig.1B). The contactor may include second and third pairs of terminals 33, 34, 42, 43, each pair corresponding to phases of a multiphase power supply. Each terminal has a separate associated measurement circuit 66, 67, 81, 82 producing measurement signals SM3-SM6. In this case, the signal processor may also evaluate whether the switching-contacts are synchronised. A method of monitoring the contactor as the switching contacts are closed, wherein the measurement signals depend on the voltages tapped at the input- and output-terminals, is also disclosed.
