Abstract:
Provided are a method and apparatus for sending Hybrid Automatic Repeat Request Acknowledge (HARQ-ACK) information. The method includes: when a terminal employs a physical uplink control channel (PUCCH) format 3 to transmit HARQ-ACK information and the HARQ-ACK information is transmitted over a uplink physical shared channel (PUSCH), determining the number of downlink subframes for serving cells to feed back the HARQ-ACK information; determining the number of encoded modulated symbols required for sending the HARQ-ACK information according to the determined number of downlink subframes; and mapping the HARQ-ACK information to be sent to the PUSCH of a specified uplink subframe according to the number of encoded modulated symbols and sending the HARQ-ACK information. The technical solutions provided by the disclosure are applied to improve the performance of the HARQ-ACK information, and thus improve the data performance.
Abstract:
A retransmission method for a time division duplexing self-adaptive frame structure, and a network side device relate to a technology of dynamically allocating uplink and downlink sub-frames in an LTE-advance (3GPP Release11) TDD communication system. The method comprises: during transmission of a TDD self-adaptive frame, for an uplink sub-frame, if a frame structure, of which an RTT period of PHICH and PUSCH of the uplink sub-frame is 10 ms, corresponding to the uplink sub frame is found in 7 types of defined frame structures, then sending PHICH data on a corresponding downlink sub-frame in the found frame structure, and sending retransmission data on the corresponding uplink sub-frame in the found frame structure. The solution ensures HARQ compatibility of an uplink data channel of R10UE. In addition, A/N feedback of the PDSCH is configured according to the uplink A/N resolution, thereby improving retransmission performance.
Abstract:
The present invention provides a method and user equipment for transmitting a physical uplink control channel. The method includes: in a carrier aggregation scenario, based on a predetermined rule, the transmission of the Physical Uplink Control Channel (PUCCH) is switched between a secondary component carrier and a primary component carrier, or the transmission of the PUCCH is only in the primary component carrier, which is selected by the user equipment (UE); and the UE transmitting the PUCCH in the selected component carrier. The present invention reduces the feedback time delay of uplink control information, and improves the utilization of uplink resources.
Abstract:
A base station, a terminal, a system and methods for performing data transmission in a Time Division Duplex (TDD) system are disclosed. One of the methods includes: the base station sending an uplink scheduling grant signaling to the terminal on a carrier m, and after receiving uplink data sent by the terminal through a Physical Uplink Shared Channel (PUSCH) on a carrier n, the base station sending an ACK/NACK feedback signaling corresponding to the PUSCH to the terminal on the carrier m; wherein, m≠n; a timing relationship between a subframe by which the base station sends the uplink scheduling grant signaling and/or the ACK/NACK feedback signaling and a subframe where the PUSCH is located is identical with a Hybrid Automatic Repeat Request (HARQ) timing relationship corresponding to an uplink/downlink configuration of the carrier m or the carrier n.
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:
A query pipeline is created (514) from a query request. The query pipeline includes multiple query operations including multiple query operators. A first query operator and a second query operator perform first and second query operations on a database (526) and on data outside the database (534). A result from the first query operation in the query pipeline is fed to the second query operation in the query pipeline.

A method for sending uplink scheduling grant signaling and a base station, applied in an Advanced Long Term Evolution (LTE-A) system, the method includes: a base station, according to a number of clusters occupied with non-consecutive resource allocation by a Physical Uplink Shared Channel (PUSCH) of a scheduled user equipment in a component carrier, configuring at least one uplink scheduling grant signaling for the user equipment, wherein each uplink scheduling grant signaling indicates an allocation of resource for one or two clusters occupied by the PUSCH; and the base station allocating a Physical Downlink Control Channel (PDCCH) for each uplink scheduling grant signaling, and sending the uplink scheduling grant signaling to the user equipment. The flexibility of the resource allocation in the case of multiple clusters is enhanced, meanwhile the reliability of transmission of the scheduling grant signaling is ensured.
Abstract:
The invention discloses a method for generating a group identifier of the random access response message. The group identifier is determined according to the serial number of the subframe in which the random access time slot of random access preamble message transmitted by the terminal lies and the serial number of the random access channel in which the random access time slot lies. A random access method and a random access response method in a cellular radio communication system are also provided. Using the method of the present invention, the terminal needs not acquire the absolute system time of the cellular system in which the random access time slot lies, and can access the cellular radio communication system rapidly and accurately.
