Abstract: Disclosed is a transmission method for a downlink control signal in a MIMO communication system where multiple transmit antennas and multiple receive antennas are used, in which each data transmitted from the multiple transmit antennas is transmitted with a different control signal through one downlink control signal transmission channel. The transmission method for a downlink control signal in a MIMO communication system efficiently transmits or receives data by transmitting control information such as a different modulation method and the number of OVSF codes of each transmit antenna to a mobile station. Also, a control channel is similar to that used in the conventional HSDPA system, thus allowing backward compatibility. Additionally, the transmission method can be applied not only for data transmitted to each antenna being composed of one packet but also for data transmitted to each antenna being composed of multiple packets.

Abstract: When a SET receives a positioning service from a V-SLP by performing a roaming from a H-SLP to the V-SLP in a SUPL-based positioning system, only a new TLS connection is generated using an abbreviated handshake protocol without generating anew TLS session after the roaming.

Abstract: Disclosed is a method for requesting a triggered location service between terminals in an SUPL-based location information system, and more particularly, a method for requesting a triggered location service related to an area event. When a triggered service of a second terminal is requested in a certain area from a first terminal, a network of the first terminal transfers the triggered service request to a second network of the second terminal. The second network initiates a positioning session with the second terminal, exchanges positioning messages and calculates a location of the second terminal, then compares the calculated location with a certain area set by the first terminal, and notifies area event occurrence in the certain area to the first terminal.
