Problems solved by technology

[0009] It can be seen from the above description that only QPSK modulation is supported in the prior art, and 16QAM cannot be supported, which may result in limited system capacity; moreover, the downlink data transmission method in the prior art requires the UE to receive and blindly decode the data of each TTI, UE consumes a lot of power

Embodiment 1

[0136] In this embodiment, it is assumed that the information carried on the HS-SCCH includes HS-PDSCH physical resource information, PTR pointer, number of transmissions, and UE ID; the Node B only allocates one type of TBS to the UE.

[0137] Figure 6 It is a schematic flow chart of the data transmission method in Embodiment 1 of the present invention, such as Figure 6 As shown, the method includes:

[0138] Step 601: The network side notifies the UE of data transmission-related control information through high-layer signaling such as RRC signaling.

[0139] Wherein, the data transmission-related control information may include: HS-PDSCH physical resource information, modulation mode, feedback mode, correspondence between HS-PDSCH physical resource and HS-SICH. Wherein, the HS-PDSCH physical resource information may also be indicated through the HS-PDSCH physical resource information carried in the HS-SCCH, and the feedback mode may also be directly set in the UE.

Embodiment 2

[0152] In this embodiment, it is assumed that the information carried on the HS-SCCH includes HS-PDSCH physical resource information, transmission times, UE ID, PTR pointer, modulation mode indication, and transport block size (when the transport block size information is used, generally The Node B allocates at least two transport block sizes to each UE).

[0153] Figure 7 It is a schematic flow chart of the data transmission method in Embodiment 2 of the present invention, such as Figure 7 As shown, the method includes:

[0154] Step 701: The network side notifies the UE of data transmission-related control information through high-layer signaling such as RRC signaling.

[0155] Wherein, the data transmission-related control information at least includes: HS-PDSCH physical resource information, feedback mode, correspondence between HS-PDSCH physical resource and HS-SICH, and transport block size information. Certainly, the relevant control information preferably also inc...

Embodiment 3

[0171] In this embodiment, it is assumed that the information carried on the HS-SCCH includes HS-PDSCH physical resource information, PTR pointer, number of transmissions, UE ID, and monitoring time indication, and the Node B allocates only one TBS for the UE.

[0172] Figure 8 It is a schematic flow chart of the data transmission method in Embodiment 3 of the present invention, such as Figure 8 As shown, the method includes:

[0173] Step 801: The network side notifies the UE of data transmission-related control information through high-layer signaling such as RRC signaling.

[0174] Wherein, the data transmission-related control information at least includes: HS-PDSCH physical resource information, modulation mode, feedback mode, correspondence between HS-PDSCH physical resource and HS-SICH, and TBS.

[0175] Step 802: When the Node B determines to notify the UE of the corresponding information through the HS-SCCH, the Node B determines the HS-PDSCH physical resource, PT...

Abstract

The invention discloses a data transmission method. The method comprises the following steps that: when a base station Node B sends control information to terminal UE through a high-speed sharing control channel HS-SCCH, the HS-SCCH carries physical resource information of a high-speed physical downlink sharing channel HS-PDSCH needed to be monitored by the UE, a UE identification ID, a PTR pointer and transmission frequency, and also carries a modulation mode instruction, a transmission block size, an HS-SCCH circulation serial number HCSN, an incremental redundancy version number, a high-speed sharing information channel HS-SICH instruction, a feedback mode, a monitoring time instruction, and one or more kinds of control information in resource adjusting time. The invention also discloses a data transmission device and a system. The method, the device and the system can flexibly change the control information of data transmission.

Description

technical field [0001] The present invention relates to data transmission technology, in particular to a data transmission method, device and system. Background technique [0002] In High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) technology, the High Speed ​​Shared Control Channel (HS-SCCH, Shared Control Channel for HS-DSCH) is used to carry the High Speed ​​Physical Downlink Shared Channel (HS-PDSCH, High Speed ​​Physical Downlink SharedChannel) scheduling and control information, for each HS-PDSCH transmission time interval (TTI, Transmission Time Interval), the downlink control information of the terminal (UE) carried by HS-SCCH is shown in Table 1, including: transmission format resources Combination (TFRI), generally 13 bits (bit), indicates the transmission format of the subsequent HS-PDSCH, including the time slot of HS-PDSCH, and code channel information; modulation method (1 bit); transport block size (TBS, Transport Block Size), ...
