摘要： Certain aspects of the present disclosure relate to methods and apparatus for data transmission in synchronization slots. A method for use by a base station for data transmission in synchronization slots includes transmitting a synchronization signal (SS) burst, wherein different SS blocks of the burst are transmitted using different transmit beams and performing frequency division multiplexing (FDM) or time division multiplexing (TDM) to include one or more other types of signals that need to be multicast and are also transmitted using the different transmit beams

摘要： A method of operating a terminal device and network infrastructure equipment in a wireless telecommunications system for communicating on a primary cell supporting a primary component carrier on radio resources within a first frequency band and a secondary cell supporting a secondary component carrier on radio resources within a second frequency band. The infrastructure equipment establishes a plural configuration settings for the secondary carrier based on measurements of radio usage in the second frequency band, which are conveyed to the terminal device. The terminal device makes channel quality measurements for the secondary component carrier according to the different configuration settings and reports these to the infrastructure equipment. Based on the measurements of channel quality for the different configurations, the infrastructure equipment selects one of the configuration settings, and conveys an indication of this to the terminal device in association with an allocation of transmission resources on the secondary component carrier.

摘要： A transmission control device includes a memory and a processor connected to the memory. The processor executes a process including: selecting a reference transmission point as a starting point of generating a link from among a plurality of transmission points of which each wirelessly transmits a signal; sequentially selecting the transmission points one by one for each hierarchy corresponding to a number of hops from the selected reference transmission point and retrieving ones of the transmission points for which radio quality between the ones and the selected transmission point satisfies a predetermined criterion; and generating a link between the selected transmission point and a transmission point, among the transmission points obtained as a result at the retrieving, not connected to others of the transmission points to connect the two transmission points.

摘要： Method and devices determine parameters governing a concatenated reference signal design based on Zadoff-Chu sequences and having a limited correlation with other reference signals arriving at a same transmission point, wherein the concatenated reference signal has a controlled cubic metric. The cubic metric control is achieved by selecting base sequence root indices, phase shifts and/or block configurations in view of information related to the other reference signals.

摘要： A method for correcting an error in the generation of a frequency by a frequency synthesizer of a terminal of a terrestrial wireless communication system. A query message is transmitted by the terminal. Error in the generation of the frequency of the query message is estimated by an access network as a function of a theoretical transmission frequency of the query message by the terminal and an actual frequency of reception of the query message by the access network. A response message comprising an item of correction information is transmitted by the access network. A frequency of reception by the terminal of a broadcast signal transmitted by the access network is generated by the frequency synthesizer of the terminal and as a function of the item of correction information received by the access network.

摘要： A device and method for communicating frequency-coded symbols that include data elements and reference symbols are disclosed. In one aspect, a carrier frequency band includes a plurality of subcarrier frequency bands. Data elements are transmitted and received on respective pairs of adjacent subcarrier frequency bands to provide diversity. Reference symbols are transmitted and received on predetermined subcarrier frequency bands. Muting is applied to selected subcarrier frequency bands based on the number and frequency configuration of the reference symbols.

摘要： A mobile station apparatus includes a transmission circuit or circuitry. The mobile station apparatus is configured to transmit a sounding reference signal (SRS) in a single carrier-Frequency Division Multiple Access (SC-FDMA) symbol corresponding to an SRS symbol. In addition, the mobile station apparatus is configured to, in a case that a region for SRS transmission on a given component carrier is extended based on a higher layer signal, transmit a first SRS in the SC-FDMA symbol, and transmit a second SRS in the extended region, where the first SRS is an SRS transmitted based on a first higher layer signal and the second SRS is an SRS transmitted based on a second higher layer signal and an SRS request in a physical downlink control channel (PDCCH).

摘要： The present invention provides a processing method based on an OFDM-TDMA two-way service and a communications device. The method includes assigning timeslots in a TDMA frame structure to multiple users in a TDMA manner, so that each user has a different timeslot, and each timeslot of the users is simultaneously used for uplink and downlink communication. The methods further includes simultaneously sending a local-end OFDM signal and receiving a remote-end OFDM signal in each timeslot of the users, and cancelling, in an OSD manner, interference caused by an echo OFDM signal, which is produced according to the local-end OFDM signal, to the remote-end OFDM signal, where a spectrum of the echo OFDM signal and a spectrum of the remote-end OFDM signal overlap.

摘要： The present disclosure describes a method for displaying data products onto a geospatial map in real-time using a computer program. In one version, the method includes the steps of monitoring the one or more directories of one or more computer readable media for newly created data products, automatically reading the newly created data products, correlating positional information of the data products with the geospatial map of the computer program for mapping and exploitation, and rendering information onto the geospatial map indicative of the area covered by each newly created data product.
