Embodiment 2

[0067] Embodiment 2 is a method of indicating time slots in a coding manner. From the above setting of TBS, it can be known that only 4 types of transport blocks (TBS) are set for selection in the present invention. Therefore, fewer combinations of time slots can be used to carry these 4 combinations of TBSs. Therefore, the present invention can indicate the HS-PDSCH time slot by using less bit time slot indication information in a coding manner. For example, see figure 2 As shown, when 5 time slots are allocated to the downlink, 2-bit time slot specification information may be used to indicate different time slot combinations, and the time slot combination is composed of two time slots connected to each other. For example, when the time slot indication information transmitted by the HS-SCCH channel is 00, it means that the corresponding HS-PDSCH channel will use TS2 and TS3 time slots, and 01 means that the corresponding HS-PDSCH channel will use TS3 and TS4 time slots, 10...

Abstract

The embodiment of the invention discloses a method that sends control information on a high speed sharing control channel, comprising: selecting the control information required by a data service transmission; arranging the control information according to request that transmission can be made in a same code channel; carrying the control information coded to a code channel of the high speed sharing control channel to be sent. The invention is able to simplify the control information on the high speed sharing control channel, which sends the control information on a same code channel, saving network resource as well as improving system volume at the same time.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for sending control information on a high-speed shared control channel. Background technique [0002] HSDPA (High Speed ​​Downlink Packet Access) includes 2 downlink channels: HS-SCCH (High Speed ​​Shared Control Channel) and HS-PDSCH (High Speed ​​Physical Downlink Shared Channel) channel . Wherein, the HS-PDSCH channel is used to carry downlink service data, and the HS-SCCH channel is used to carry control information related to the HS-PDSCH service data. [0003] The existing 1.28M HS-SCCH channel in Time Division Duplex (TDD, Time Division Duplex) mode uses two code channels with a spreading factor of 16 (ie SF16) for carrying, and one of the code channels contains the uplink synchronization control word Control information of SS and uplink power control control word TPC, wherein the SS and TPC are mainly used for synchronization and power control of the uplin...
