Abstract
The invention discloses a method for configuring a shared control channel of a high-speed down-link shared channel and a device to carry out the method. The method comprises the following steps that: a wireless network controller informs a base station of a channel code and/or scramble of a shared control channel available in a high speed down-link shared channel which is in a strengthened connection mode state via a signaling; the base station obtains the channel code and/or scramble from the signaling and returns a common transport channel setup response message or a common transport channel re-configuration response message to the wireless network controller; and when the base station needs to transmit the data in a strengthened connection mode state, the channel code and/or scramble is used for frequency enlargement and scrambling transmit the information loaded on the shared control channel to be used in the high speed down-link shared channel. The invention can ensure that the user equipment in a strengthened connection mode state can accurately receive the data of high speed physical down-link shared channel so as to ensure the service quality for the user.
Description
Technical field
The present invention relates to the communications field, relate more specifically to a kind of collocation method and device that is used for the shared control channel of high speed descending sharing channel.
Background technology
In order to improve the throughput of high data traffic of user and system, the R5 standard agreement of 3GPP has been introduced a kind of high-speed packet and has been shared transmission channel (High Speed Downlink SharedChannel, be called for short HS-DSCH), the physical channel that this channel shone upon adopts time-division and sign indicating number branch mode, and this channel has adopted and has mixed (HARQ) and Adaptive Modulation and Coding (AMC) technology of retransmitting automatically, makes peak rate can reach 10.8Mbps～30Mbps.Its final purpose is to increase the capacity of system and reduce transmission delay by providing high speed packet service to insert, thereby improves the requirement of user to service quality (Qos).
Now the 3GPP consensus standard to Radio Resource control (RRC) connection mode down front access state (CELL_FACH) and (or) Radio Resource control (RRC) connection mode paging state (CELL_PCH/URA_PCH) down strengthens, promptly CELL_FACH and (or) the CELL_PCH/URA_PCH state also can use the high speed shared channels (will be in CELL-FACH and (or) CELL_PCH/URA_PCH state use and share grouping access (HSDPA) technology at a high speed and abbreviate reinforcement connection mode common condition as) at this.Yet the principle of high speed shared channels technology is: thereby subscriber equipment needs at first to monitor the signaling parameter that is used for the shared control channel (HS-SCCH) of high speed descending sharing channel obtains high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH) by the temporary identifier of wireless network (H-RNTI) of high speed descending sharing channel, could receive the data of high-speed physical downlink shared channel (HS-PDSCH) then.
When subscriber equipment is in reinforcement connection mode common condition, owing to there is not dedicated process, so the base station need be known the spendable code resource information of strengthening under the connection mode common condition that is used for the shared control channel of high speed descending sharing channel of subscriber equipment in advance, just can use correct channel code and scrambler that the signaling information that carries on the shared control channel that is used for high speed descending sharing channel is carried out spread spectrum and scrambling and send, just can guarantee to strengthen subscriber equipment under the connection mode common condition and correctly receive data on the high-speed physical downlink shared channel (HS-PDSCH).
Therefore, need a kind of method or device that is used for configurating base station at the shared control channel of strengthening using under the connection mode common condition that is used for high speed descending sharing channel, send so that the base station can use correct channel code and scrambler that the signaling information that carries on the shared control channel that is used for high speed descending sharing channel is carried out spread spectrum.
Summary of the invention
In view of above-mentioned one or more problems, the present invention proposes and be used for the method and apparatus of configurating base station at the shared control channel of strengthening using under the connection mode common condition that is used for high speed descending sharing channel.
The configurating base station that is used for according to the present invention may further comprise the steps in the method for the shared control channel of strengthening using under the connection mode common condition that is used for high speed descending sharing channel: step S102, and radio network controller is being strengthened spendable channel code and/or the scrambler that is used for the shared control channel of high speed descending sharing channel under the connection mode common condition by the signaling base station; Step S104, the base station obtains channel code and/or scrambler from signaling, and returns Common transport channel to radio network controller and set up response message or Common transport channel reconfiguration response message; And step S106, when the base station need send the data of strengthening high speed descending sharing channel under the connection mode common condition, use channel code and scrambler that loaded information on the shared control channel that is used for high speed descending sharing channel is carried out spread spectrum and scrambling transmission.
Wherein, signaling comprises following any one or combination: Common transport channel is set up message and Common transport channel reconfiguration message.Channel code is a plurality of.The span of channel code is 0-127 or 0-255.Channel code with following any one be associated: logic channel, transmission channel, media access control flow, priority query or strengthen available channel code or set under the connection mode common condition.
Scrambler can be fixed as the scrambler of Primary Common Pilot Channel, and this moment, radio network controller only passed through the signaling base station with channel code.Scrambler also can be main scrambler and auxilliary scrambler, and this moment, radio network controller passed through the signaling base station with channel code and scrambler.The span of scrambler is 0-15.
The configurating base station that is used for according to the present invention comprises at the device of the shared control channel of strengthening using under the connection mode common condition that is used for high speed descending sharing channel: notification unit is used for strengthening spendable channel code and/or the scrambler that is used for the shared control channel of high speed descending sharing channel under the connection mode common condition by the signaling base station; Acquiring unit is used for obtaining channel code and/or scrambler from signaling, and returns Common transport channel to radio network controller and set up response message or Common transport channel reconfiguration response message; And processing unit, when being used for sending the data of reinforcement connection mode common condition in the base station, use channel code and/or scrambler that loaded information on the shared control channel that is used for high speed descending sharing channel is carried out spread spectrum and scrambling transmission.
By the present invention, can be so that the base station can use correct channel code and the signaling information that carries on the shared control channel that is used for high speed descending sharing channel is carried out spread spectrum to scrambler and scrambling sends, thereby can guarantee to strengthen subscriber equipment under the connection mode common condition and correctly receive data on the high-speed physical downlink shared channel (HS-PDSCH), thereby guarantee quality of services for users.
