摘要:
A method and corresponding equipment, the method for enabling a Node B/base station to distinguish different states--HARQ active states and a DTX (non-transmitting) state--of a UE in respect to use of the feedback HSDPA (high-speed downlink packet access) channel HS-DPCCH over which the UE sends acknowledgement messages (ACK/NACK) to tile Node B in response to receiving packets via the HSDPA (downlink) data channel HS-DPCH, the method including steps in which the UE additionally sends preamble symbols if an acknowledgement message (ACK/NACK) is to be sent in a next time interval but not in the current time interval, and at least one postamble symbol prior to the UE entering the non-transmitting state (DTX).

The present invention relates to a method for establishing a random access type connection and a subscriber terminal equipment (37 to 38) and a radio system operating in accordance with the method. The subscriber terminal equipment (37 to 38) establishes a connection to several base stations (33 to 36). The base stations (33 to 36) are selected before establishing the connection by deducing the quality of the connection by means of pilot signals and both uplink and downlink interferences. The subscriber terminal equipment (37 to 38) has a connection to several base stations (33 to 36) already at the initial stage of the connection.
摘要:
The invention relates to a method for transmitting packet switched data in a mobile communications system using an ARQ protocol. In the method the receiver orders the desired transmission units. The transmitter sends transmission units according to the order. Ordering and transmission are repeated until the quality measured by the receiver from each packet exceeds the predetermined quality value and the data which is to be transmitted and consists of packets is transmitted from the transmitter to the receiver. The invention also rebates to a mobile communications system implementing the method of the invention.
