Abstract:
A method for reporting channel state information is provided in the invention, which includes: an eNB (eNodeB) indicating UE to feed back CSI (channel state information) reporting of one or multiple component carriers at a time; the UE feeds back the CSI reporting of one or multiple component carriers at a time according to the indication of eNB. The invention also provides an eNB, which is configured to: indicate UE to feed back CSI reporting of one or multiple component carriers at a time. In the invention, the problem how the UE performs channel state information reporting for multiple (downlink) component carriers in the LTE-A system is solved, which can not only ensure the reliability of transmitting channel state information but also reduce the feedback delay of channel state information as soon as possible.
Abstract:
Sensors suitable for the sensing/detection of biological or chemical agents may be fabricated by immobilizing biological and/or chemical recognition components (selectors or probes) on a substrate by the polymerization of a suitable monomer in the presence of the selectors or probes, for example, by Polysiloxane Monolayer Immobilization (PMI). PMI may involve the polymerization of polysiloxane onto a substrate, onto which selector molecules are adsorbed or otherwise immobilized. The resulting immobilized selector molecule may then be used to interact with specific molecules (targets) within a mixture of molecules, thereby enabling those specific molecules to be detected and/or quantified.
Abstract:
The disclosure provides a physical uplink control channel (PUCCH) power control method. A user equipment (UE) determines a power control parameter nHARQ for a PUCCH format 3 transmission and performs power control on the PUCCH format 3 based on the nHARQ. The disclosure also provides a PUCCH power control apparatus. According to the disclosure, for a TDD system, the power control parameter nHARQ for the PUCCH format 3 transmission may be determined, which efficiently solves the problem regarding power control when feedback is performed in PUCCH format 3.
Abstract:
A logging system includes an event receiver and a storage manager. The receiver receives log data, processes it, and outputs a column-based data “chunk.” The manager receives and stores chunks. The receiver includes buffers that store events and a metadata structure that stores metadata about the contents of the buffers. Each buffer is associated with a particular event field and includes values from that field from one or more events. The metadata includes, for each “field of interest,” a minimum value and a maximum value that reflect the range of values of that field over all of the events in the buffers. A chunk is generated for each buffer and includes the metadata structure and a compressed version of the buffer contents. The metadata structure acts as a search index when querying event data. The logging system can be used in conjunction with a security information/event management (SIEM) system.
Abstract:
A radio frame and method are provided for sending a sounding reference signal (SRS) in a mobile communication system, which is used to solve the problem of shortage of resources for sending the SRS in the mobile communication system. The method includes a user equipment (UE) sending the SRS to eNB in time-frequency resources corresponding to a guard space in the radio frame, wherein, the guard space is one or more of downlink to uplink guard space, uplink to downlink guard space, reserved subframes, or reserved idle resources. A device is also provided for sending the SRS, applied to the UE in the mobile communication system, wherein the device includes a radio frame construction module and a sounding reference signal transmission module.
Abstract:
A signal transmission method in a Time Division Duplex (TDD) system is disclosed. The method comprises following steps: within a time length of a half-frame of a radio frame, base station transmits signal on a downlink special time slot, thereafter does not transmit signal on a Guard Period (GP), and then receives signal on an uplink special time slot; all time lengths of other uplink or downlink normal time slots for transmitting signal are equal; the total time length of the downlink special time slot, the guard period and the uplink special time slot is integer times of the time length of an uplink or downlink normal time slot. In addition, a frame structure adopted in the TDD system which corresponds to the method is disclosed. The present invention makes it flexible to set the duration of the GP and it is guaranteed that, even if a synchronization signal adopts power promotion, it will not bring great interference to uplink reception of other base stations; in addition, the utilization efficiency of the system is improved.
Abstract:
Disclosed are a method and device for sending hybrid automatic repeat request acknowledge information. The method includes: in a TDD system, configuring a terminal to employ a PUCCH format 1b with channel selection method to send HARQ-ACK information; bundling the HARQ-ACK information of downlink subframes of serving cells in a bundling window corresponding to a specified uplink subframe to obtain HARQ-ACK information to be sent by the serving cells; and sending the HARQ-ACK information over an uplink subframe via the PUCCH or PUSCH. By way of bundling the HARQ-ACK information of downlink subframes of serving cells in a bundling window corresponding to a specified uplink subframe, the disclosure can realize sending the HARQ-ACK information when serving cells with different uplink and downlink configurations are aggregated.
Abstract:
The present disclosure provides a method for reducing the transmission power of an uplink signal, comprising: performing, by a User Equipment (UE), Component Carrier (CC) grouping on configured uplink CCs; and comparing correspondingly the transmission power of an uplink signal in each CC group with a maximum transmission power configured for the each CC group by an evolved Node B (eNB), and performing a power reduction within the CC group when the comparison result meets an intra-group power reduction condition; and/or comparing the sum of transmission powers of uplink signals in all CC groups with a maximum transmission power configured for the UE by the eNB, when the comparison result meets an inter-group power reduction condition, performing a power reduction between the CC groups. The present disclosure further provides a device for reducing the transmission power of an uplink signal. The technical solution of the present disclosure can improve the covering capability and reliability of the uplink signal in an Inter-band CA scenario, and to improve a utilization rate of a UE's uplink transmission power.
