Problems solved by technology

However, when the multi-stream transmission system adopts the existing protocol to realize repeated feedback of HARQ-ACK and CQI, the repetition factor parameters configured by each cell (or base station) are different, and the scheduling is inconsistent, which will cause the base station to combine HARQ-ACK and / or CQI. Decoding error occurred
[0007] For the problem of realizing HARQ-ACK and / or CQI repeated transmission in a multi-stream transmission system, no effective solution has been proposed so far

Embodiment 1

[0067] This preferred embodiment provides a method for sending control data in a multi-stream transmission system, which can realize that the base station correctly receives the repeated transmission of HARQ-ACK. The method includes: the repetition factor N_acknack_transmit of the HARQ-ACK transmission is greater than 1; the base station schedules the multi-stream terminal on the subframe whose HS-SCCH subframe number satisfies a specific condition.

[0068]Preferably, the preset condition that the HS-SCCH subframe number satisfies is, (5×SFN-SchOffset+Subframe) MOD N=M, wherein, SFN is the system frame number of the system frame where the HS-SCCH subframe is located, and Subframe is the subframe number of the HS-SCCH subframe, SchOffset is a configuration parameter, and N is the repetition factor N_acknack_transmit of HARQ-ACK transmission.

[0069] Preferably, the preset condition that the HS-SCCH subframe number satisfies is, (5×SFN-(5×SFN Offset +Subframe Offset +SchOffs...

Embodiment 2

[0074] In this preferred embodiment, a terminal scheduling method is provided. In this preferred embodiment, in a multi-stream transmission system, in order to improve the performance of the base station receiving the HS-DPCCH channel and reduce the power of the terminal transmitting the HS-DPCCH, you can A method in which the terminal repeatedly sends HARQ-ACK and / or CQI is adopted. In order to ensure that the base station can correctly combine and decode repeated HARQ-ACK and / or CQI indications, the network side controls each serving cell in the multi-stream transmission to schedule the subframe of the terminal, so that each serving cell schedules the subframe of the terminal to coincide with the subframe of the terminal. The HS-SCCH subframe pairings of the serving cells corresponding to the terminal are kept synchronized.

[0075] For example, if Figure 5 As shown, it is assumed that the pairing of the time reference cell (Time reference cell) and the non-time reference ...

Embodiment 3

[0085] This embodiment provides a method for a terminal to repeatedly send an HARQ-ACK indication in a multi-stream transmission system, such as Figure 12 As shown, the following steps S1202 to S1216 are included.

[0086] Step S1202: UE configures a multi-stream transmission function;

[0087] Step S1204: The RNC configures the UE to repeatedly transmit the repeated transmission factor indicated by the HARQ-ACK as N and / or the repeated transmission factor indicated by the CQI as N';

[0088] Step S1206: RNC determines SchOffset in formulas (1) and (2) in the above preferred example TimeRef and SchOffset NonTimeRef , and are respectively transmitted to the base station corresponding to the time reference cell and the base station corresponding to the non-time reference cell of the terminal through NBAP signaling.

[0089] Step S1208: The base station corresponding to the terminal time reference cell calculates the system frame number SFN and HS-SCCH subframe number that th...

Abstract

The invention discloses a method for dispatching terminals, an apparatus and a base station. The method comprises the following steps: the base station determines that repetition factors transmitted by an HARQ-ACK is greater than 1; The base station carries out dispatching on multi-flows of terminals on a preset HS-SCCH subframe. Through the method for dispatching the terminals, the apparatus and the base station of the invention, repeated feedbacks of HARQ instructions and or CQI instructions performed by base station reception terminals in a multi-plow transmission system are realized, and the reception performance is raised.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a terminal scheduling method and device, and a base station. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA for short) is a technology proposed in Release-5 by The 3rd Generation Partnership Project (3GPP for short) , which is used to improve the network data throughput in the downlink direction (that is, the direction from the network to the terminal), and the designed cell and single-user downlink peak rate can reach 14.4Mbps. Subsequently, in order to make the downlink peak rate higher, the new technology of High Speed ​​Packet Access Evolution (HSPA+) was introduced. These technologies include the downlink 64-phase quadrature amplitude modulation (Quadrature Amplitude Modulation, referred to as QAM) high-order modulation and multiple-input multiple-output (Multiple-Input Multiple-Output, referred to as MIMO) antenna technology, dual-carrier HSDPA ...
