Method for rapidly allocating radio resources to logical channels in a down-link direction
First Claim
1. A method for signaling a data transmission from a station (BS) administering resources of a transmission channel (UL, DL) to a station (MS) registered there, in an operating mode with a shared transmission channel (DL), in which transmission information about data to be subsequently transmitted is transmitted to the registered station (MS) in a message block with a multiplicity of information items before the data transmission, characterized in that an identification information item (DSF) for identifying the later data transmission is allocated for a particular registered station (MS) in the message block, and in that subsequently (t0, tx) such a data transmission is in each case announced in a signaling channel (DLCCH) by sending out the identification information item (DSF) before the actual data transmission.

Abstract
A station manages the resources of a transmission channel to another station registered there in an operating mode in which the transmission channel is shared. Transmission information on the data that are to be consecutively transmitted is transmitted in a message block of information items to the registered station prior to the transmission of the data without requiring transmission of a complete message block to allocate resources before every data transmission. Identification information characterizing the data to be transmitted is included in the message block and data transmission is then announced in a signaling channel by transmitting the identification information prior to data transmission.

1. A method for signaling a data transmission from a station (BS) administering resources of a transmission channel (UL, DL) to a station (MS) registered there, in an operating mode with a shared transmission channel (DL),
in which transmission information about data to be subsequently transmitted is transmitted to the registered station (MS) in a message block with a multiplicity of information items before the data transmission, characterized in that an identification information item (DSF) for identifying the later data transmission is allocated for a particular registered station (MS) in the message block, and in that subsequently (t0, tx) such a data transmission is in each case announced in a signaling channel (DLCCH) by sending out the identification information item (DSF) before the actual data transmission.
-
4. The method as claimed in a preceding claim, in which the data sent out after the sending out of the identification information item (DSF) do not contain any special assignment information to the registered station (MS) for which they are intended.
-
5. The method as claimed in a preceding claim, in which a channel which is physically separate from the transmission channel (DL) is used as the signaling channel (DLCCH).
-
6. The method as claimed in a preceding claim, in which a special physical or logical control channel is used as the signaling channel (DLCCH).
-
7. The method as claimed in a preceding claim, in which the identification information item (DSF) is used for referring to one or more physical resources of the separate transmission channel (SCH1-SCH3).
-
8. The method as claimed in a preceding claim, in which the identification information item (DSF) is allocated for a predetermined period of time, particularly some seconds up to some minutes and, in particular, is subdivided into transmission periods.
-
9. The method as claimed in a preceding claim, in which the registered station (MS), after entering into the operating mode with a shared transmission channel, permanently listens to the signaling channel (DLCCH) as long as it is in this operating mode.
- 10. The method as claimed in a preceding claim, in which at least all downlink resources (SCH1-SCH3) used for the operating mode with a shared transmission channel (DL) are consecutively numbered.
-
12. A base station (BS) of a radio communication system, particularly for carrying out a method as claimed in a preceding claim, comprising
an administration device in the first station (BS) for administering resources of a transmission channel (UL, DL), and a signaling device (Y) for signaling a data transmission to at least one second station (MS) in an operating mode with a shared transmission channel (DL), in which transmission information about data to be subsequently transmitted are transmitted to the second station (MS) in a message block with a multiplicity of information items before the data transmission, characterized in that the signaling device (Y) is constructed for entering an identification information item (DSF) for identifying the transmission of data in the message block before its transmission, and in that a transmitting device for sending out a signaling channel (DLCCH) with an identification information item (DSF) is set up for the respective signaling of a later transmission of data before the data transmission.
