摘要:
A method of executing to battery power consumption between an access terminal (AT) and an access network (AN) in a wireless communication system is disclosed. More specifically, the method includes transmitting a notification message to the AN, receiving a confirmation message from the AN, and entering the power-saving mode according to the determined power saving mode. Here, the notification message includes at least one of battery life information and a power-saving mode request, and the confirmation message includes a determined power saving mode which is based on the at least one of battery life information and the power-saving mode request.

A method for relaying a signal in a wireless communication system is provided. The method comprises receiving in at least one of a base station and a relay station information regarding a mobile station group (MSG) of a mobile station, scheduling within a given duration uplink information to be transmitted from a first mobile station and downlink information to be transmitted to at least one mobile station, wherein the first mobile station is in each of the at least one mobile station's MSG, receiving in a relay station the uplink information and the downlink information to be transmitted within the given duration, network coding the uplink information and the downlink information in the relay station, and transmitting from the relay station a network-coded packet, wherein the network-coded packet can be received by the base station and the at least one mobile station.

A method and apparatus for small packet transmission in response to machine type communication (MTC) device trigger indication are provided. For uplink (UL) transmission of small packet from MTC device in idle state, a tracking area update (TAU) complete non-access stratum (NAS) message is used to protect integrity and confidentiality of UL small packet transmission without attach/service request procedure during idle state. For downlink (DL) transmission of small packet from MTC device in idle state, a TAU accept NAS message is used to protect integrity & confidentiality of DL small packet reception without attach/service request procedure during idle state.

Time synchronization of an access point base station. The method may include receiving an assignment message from a service provider comprising a plurality of parameters. The plurality of parameters may include an access point base station frequency assignment, a network identifier, an access point base station identifier, a neighbor list, a PN offset, and/or a scrambling code. The access point base station may then synchronize with the macro base station. Synchronizing may include searching for a strongest macro base station in the neighbor list, synchronizing a long code of the access point base station to the macro base station, estimating a propagation delay between the macro base station and the access point base station, and initializing a state of the access point base station PN code using the propagation delay to provide system time synchronization.
摘要:
A low density parity check (LDPC) coding method, and more particularly, a method of executing LDPC coding using a parity check matrix is disclosed. The present invention comprises providing an information bit stream for channel encoding, and encoding the information bit stream by using a first parity check matrix including at least one row generated by combining at least two rows of a second parity check matrix.
摘要:
A method of configuring a data packet including an orthogonal frequency division multiplexing (OFDM) preamble in a wireless communication system is disclosed. The method includes configuring the data packet to include the OFDM preamble in a first region, a pilot and medium access control (MAC) in a second region, and a data symbol in a third region.
摘要:
A method of transmitting channel quality information (CQI) to an access network (AN) in a system having at least one carrier is disclosed. More specifically, the method includes receiving at least one packet from the AN, each of which includes an indicator, wherein the indicator provides buffer level information and ceasing transmission of the CQI of at least one non-anchor carrier to the AN if the buffer level information indicates that there is no more packet to be transmitted to an access terminal (AT).
摘要:
A parking guidance and management system. The system provides graphical information regarding the relative availability of parking spaces within a parking garage or other large facility. The system relies on a video image sensing system wherein each space in the facility is monitored by a camera to determine whether or not it is occupied. A single camera may be used to determine the status of a plurality of spaces. The information is displayed at strategically located displays along the way to available spaces. The displays contain advertising messages adjacent to the information about space availability. Revenues generated by the sale of advertising can be used by the facility operator to defray the purchase and/or maintenance cost of the guidance and management system. The information obtained from the sensors at each parking space may be used to provide information to the manager of the facility regarding space utilization. Information regarding the occupancy status of each space may also be used as a check on receipts of parking fees and to identify abandoned vehicles.

摘要:
A method for communicating data based on an unlicensed band in a wireless communication system comprising a first type network entity and a second type network entity which is different. The first type network entity comprises a cellular base station and the second type network entity comprises a Femto-cell base station. In the method, a cellular base station identifies at least one Femto-cell base station incurring interference and instructs the identified base station to operate on an unlicensed band. The technical features can be used to improve the performance of the wireless network, and/or to reduce the effect of interference.
