Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0046] In this embodiment, a method for a UE that activates multi-stream transmission to send an HS-DPCCH is applied in a multi-stream transmission system, including: the UE that activates multi-stream transmission receives the HS-DPCCH from the primary serving cell and the secondary serving cell After the HS-PDSCH subframe, based on the later received HS-PDSCH subframe, according to the existing 3GPP 25.211 protocol, the HS bearing the jointly coded ACK / NACK and CQI indication will be sent after about 7.5 time slots -DPCCH. Among them, the 7.5 time slots are the timing rela...

Abstract

A method for activating multi-flow transmission user equipment (UE) to transmit a high speed (HS)- dedicated physical control channel (DPCCH) and the UE. The method is applied to a multi-flow transmission system. The method includes that the UE for activating multi-flow transmission transmits the HS- DPCCH bearing the joint coded acknowledgment character (ACK) / non-acknowledgment character (NACK) and a channel quality indicator (CQI) after set time with an HS-PDSCH subframe received later in a pair of HS-PDSCH subframes which are paired after the UE receives a high speed physical downlink shared channel (HS- PDSCH) subframe transmitted by a main service cell and an auxiliary service cell. The preset time is determined by the timing relation between the HS-DPCCH transmitted by the UE and the corresponding HS-PDSCH receiving subframe and regulated in third generation partner plan (3GPP) 25.211 protocol. The existing protocol is reused by means of the method and the UE.

Description

technical field [0001] The present invention relates to a multi-stream transmission technology in a mobile communication system, in particular to a method for a UE (User Equipment, user equipment) that activates multi-stream transmission to send HS-DPCCH and the UE. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA for short) is a technology proposed by the 3rd Generation Partnership Project (3GPP for short) in Release-5 , which is used to improve the network data throughput in the downlink direction (that is, the direction from the network to the terminal), and its designed cell and single-user downlink peak rate can reach 14.4Mbps. Subsequently, in order to make the downlink peak rate higher, HSPA+ (High Speed ​​Packet Access Evolution, evolved high-speed packet access) new technology was introduced. These technologies include the downlink 64QAM (Quadrature Amplitude Modulation, quadrature amplitude modulation) proposed in Release-7. Modulation) hig...
