Embodiment Construction

[0027]In this embodiment, a method for realizing paging by using high-speed packet access enhancement in a time division duplex system is provided.

[0028] like figure 2 As shown, the method for implementing paging in a time division duplex system according to this embodiment using enhanced high-speed packet access includes: step S202, the Node B sends PI on the PICH, and then sends a paging message on the HS-PDSCH, Wherein, the PI contains transmission format information; step S204, the UE listens to the paging indicator channel, and when judging that the PI at the PI position corresponding to its own identity is valid, obtains and processes the PI from multiple PI positions according to predetermined rules and processes the The PI value of the predetermined condition is used to obtain the transmission format information; and step S206, the UE uses the transmission format information to decode the HS-PDSCH according to the paging message reception timing, and obtains the pa...

Abstract

The invention discloses a paging implementing method using high-speed packet access reinforcement technique in the time division duplex system, comprising that a node B sends a paging message, the user equipment receives the paging message, and the node B sends a paging block. The paging block is composed of a paging indicator channel PICH and a plurality of paging sub-channels. A determined timing interval is provided between a PICH block and a first paging sub-channel in the paging block. Paging sub-channels of the same paging block are distributed on a continuous radio frame. Sending paging message in the paging sub-channels is continuously sending the same message m1 times, wherein m1 is determined by occupied radio frame number n of each paging sub-channels in the paging block. Using the invention, blind decoding of UE is avoided without additional signaling expense while implementing paging, so that process complexity and energy consumption of UE is lowered when receiving.

Description

technical field [0001] The present invention relates to a paging method utilizing high-speed packet access enhancement in a Time Division Duplex (TDD) system (especially a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system), wherein , can realize the use of IMSI (International Mobile Subscriber Identity, IMSI) of UE (User Equipment, referred to as UE) to calculate the receiving timing of paging messages and listen to the high-speed downlink shared channel HS-DSCH (High Speed ​​Downlink Shared Channel, referred to as HS-DSCH) paging message on the channel. Background technique [0002] Wideband Code Division Multiple Access (WCDMA) introduces Cell_Forward Access Channel (CELL_FACH) enhanced technology on the basis of High Speed ​​Downlink Physical Access (HSDPA) technology. The CELL_FACH enhancement technology introduces a high-speed downlink shared channel (HS-DSCH) transmission channel in the CELL_FACH state to enhance the packet data transmission pe...
