Component for insertion into a cellular communication network to reduce redundant signaling on the network or between the network and other networks, comprises: an extractor, to extract signaling passing the insertion point towards a destination, modify the signaling and reinsert the signaling for sending onwards. The extractor comprises a signal part remover to remove a part determined to be present at the destination; and an inserter for inserting a flag into the signaling to indicate the removal. The modified signal is sent on to the destination where a complementary component reads the flag and reinserts the extracted part from a database of its own. Location update activity often involves redundant transfer of user profiles, which the components herein can save.

Embodiments of a system and method for reporting channel state information (CSI) in a wireless network are generally described herein. In some embodiments, an apparatus of a User Equipment (UE) can include physical layer circuitry to receive, in a first subframe, a first aperiodic CSI request from a first cell group, and a second aperiodic CSI request from a second cell group. The UE can include processing circuitry to determine a number of requested CSI processes corresponding to the first aperiodic CSI request and the second aperiodic CSI request. Additionally, the processing circuitry can select a subset of the requested CSI processes when the determined number of requested CSI processes is more than five. Furthermore, the processing circuitry can calculate CSI for the selected CSI processes.

The present application discloses a method for transmitting uplink control information, a user equipment, and a base station. The method includes: receiving a physical downlink control channel sent by a base station, where the physical downlink control channel includes indication information, where the indication information is used to indicate a physical uplink control channel resource used to transmit uplink control information; obtaining, according to the indication information and whether the uplink control information includes periodic channel state information, a physical uplink control channel resource used to transmit the uplink control information from a semi-statically configured first resource group and/or second resource group; and sending the uplink control information to the base station over a physical uplink control channel corresponding to the physical uplink control channel resource.

Multiple full channel quality indication (CQI) reports indicative of received signal quality for multiple carriers in wireless communication are transmitted in multiple time intervals of a CQI channel.

The present invention relates to reporting the channel state information in a communication system. The channel state information is reported from the user terminal to a base station. Accordingly, the user terminal determines a first channel state information value from a first set of values (levels) and a second channel state information value from another set of values, preferably a larger set of values. Then a difference or other relative measure is calculated between the first and the second channel state information value and transmitted to the base station.

Disclosed is a method for transceiving channel state information in a wireless access system and an apparatus for the method. More particularly, the method comprises: a step of receiving, from user equipment, channel state information measurement capability indicating the total number of pieces of channel state information which can be measured by the user equipment; a step of transmitting, to the user equipment, information regarding the object for channel state information measurement set in the user equipment; and a step of receiving, from the user equipment, channel state information measured in the object for channel state information measurement. The object for channel state information measurement is restrictively set such that the total number of the objects for channel state information measurement is the same as or less than the channel state information measurement capability.

A method, apparatus and system for feeding back early stop decoding are provided. The method includes: a terminal side adjusting encoded TFCI bits, and sending the adjusted TFCI bits to a NodeB side via a TFCI domain of an uplink DPCCH (S302); after sending the adjusted TFCI bits to the NodeB side, the terminal side performing a decoding operation on a downlink DPCH, and feeding back, via an idle TFCI domain of the uplink DPCCH, a decoding result to the NodeB side (304). By applying the technical solution, at least one of the problems in the related art that a NodeB cannot obtain a TFCI in time and a terminal side cannot feed back a downlink decoding result in time during early stop decoding can be solved.

Provided are a communication device and an SRS transmission method capable of reducing the possibility of a difference in recognition between the presence or absence of an SRS transmission between a base station and a terminal or of an SRS resource so as to prevent degradation of system throughput. At a terminal (200), a reception processing unit (203) detects control information indicating whether or not to request transmission of a sounding reference signal (SRS), whereupon a transmission signal forming unit (207) transmits an A-SRS by way of control by a transmission control unit (206) on the basis of control information. The transmission control unit (206) determines whether or not to execute SRS transmission on the basis of an “SRS Transmission Execution Rule” and the reception status of trigger information.

A method reducing amount of memory utilized by hybrid automatic repeat request (HARQ) operations is disclosed. When an apparatus employing the method receives an LDPC encoded packet, the apparatus firstly estimates a signal quality value of the received packet, and performs an LDPC decoding algorithm on the received packet. If the received packet is not successfully decoded by the apparatus, the received and decoding-failed packet is compressed in order to reduce bit-width, and the compressed packet is stored in a memory device for later HARQ operations. The apparatus employing the method is also disclosed.

Disclosed are a method for a terminal to report channel state information (CSI) to a base station, and an apparatus for supporting the same. More specifically, disclosed are a method for a terminal to report CSI in a wireless communication system supporting an unlicensed band by transmitting a physical uplink shared channel (PUSCH) which only includes the CSI without an uplink shared channel (UL-SCH), and apparatuses for supporting the same.
