Embodiment Construction

[0047] see figure 1 , a basic mobile communication network 2 is illustrated in the figure, which is linked to a more distant communication network 4, such as the Internet. The mobile network 2 has a gateway mobile switching center 6 which acts as an interface between the mobile network 2 and the communication network 4 . It handles user data and signaling between the mobile network 2 and the communication network 4 . The mobile network 2 has a mobile switching center 8 linked to at least one transceiver station 10 which in turn communicates with any of the mobile stations 12, 14, mobile PC 16 or user equipment. The Base Transceiver Station 10 is also called Node B and it is the interface between the BTS 10 and the Mobile Station 12 or 14, for which the downlink in the HSDPA protocol, i.e. from the BTS 10 to the Mobile Station, the signaling scheme Improvements are suggested.

[0048] Referring to Table 1 and Table 2 described above, it should be noted that in the current p...

Abstract

A signaling method using hybrid automatic repeat request (HARQ) from a base station (10) to a mobile station (12, 14, 16) in a mobile communication network (2), said method comprising the steps of: The base station selects a code for indicating the transmission of new data or retransmitted data; provides a combination of redundancy version parameters and / or bit reorganization parameters in the selected code; and transmits the selected code to the mobile station, wherein The chosen code has the effect of increasing the number of combinations available or reducing the number of bits required for HARQ signaling.

Description

technical field [0001] The present invention relates to a signaling method and system for a mobile communication network, in particular to an improved method for using Hybrid Automatic Repeat reQuest (HARQ) in High Speed ​​Downlink Packet Access (HSDPA) Methods and systems for signaling schemes. Background technique [0002] HSDPA is a key feature in the third generation wireless communication standard Wideband Code Division Multiple Access (W-CDMA), which proposes to support multimedia services in the downlink direction. As the name suggests, HSDPA provides high-speed data transmission for third-generation (3G) terminals. For users who require effective multimedia capacity, HSDPA ensures that they can benefit from data rates that were previously unavailable due to wireless access network limitations. beneficial. In a mobile communication network, a radio access network connects user terminals and base stations. [0003] As part of Release 5 of the 3rd Generation Partners...
