Embodiment Construction

[0045] In the embodiment of the present invention, when the network side needs to send data to a terminal configured with any one of the transmission modes 1 to 8 through the unicast MBSFN subframe, the DCI (Downlink Control Information, downlink control information) format indication corresponding to the currently used transmission mode is used. Downlink scheduling information, and sending data from the port corresponding to the currently used sending mode through the unicast MBSFN subframe. Since data can be transmitted (sent or received) through the unicast MBSFN subframe in any mode of transmission modes 1-8, scheduling restrictions on services of transmission modes 1-8 are avoided and system performance is improved.

[0046] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] Such as figure 1 As shown, the data transmission system in the embodiment of the present invention includes: a ...

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a data transmission method, a data transmission system and data transmission equipment, which are used for solving the problem in the prior art that transmission modes 1 to 8 cannot transmit data by a unicast multimedia broadcast multicast service single frequency network (MBSFN) sub-frame to form scheduling limitations to services of the transmission modes 1 to 8 and influence system performance. The method of the embodiment of the invention comprises that: when required to transmit thedata to a terminal configured with any one of the transmission 1 to 8 by the unicast MBSFN sub-frame, a network side determines a downlink control information (DCI) format corresponding to a currently adopted transmission way, and determines a port corresponding to the currently adopted transmission way; and the network side indicates downlink scheduling information by the determined DCI format, and transmits the data from the determined port by the unicast MBSFN sub-frame. The data can be transmitted by the unicast MBSFN sub-frame in any one of the transmission modes 1 to 8, thereby avoidingthe scheduling limitations to the services of the transmission modes 1 to 8 and improving the system performance.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data transmission method, system and equipment. Background technique [0002] In LTE release 8 and 9 (Long Term Evolution 8 and 9) systems, MBSFN (Multimedia Broadcast multicast service Single Frequency Network, Multimedia Broadcast Multicast Service Single Frequency Network) subframes are only used to support multicast services. The MBSFN subframe is mainly composed of a control region (control region) and a multicast channel (PMCH, physical multicast channel). Wherein, the control region is the first one or two symbols of the subframe, carrying information such as uplink and downlink scheduling, power control, etc., and adopts downlink common pilot (CRS, cell-specific reference signal) embedded therein for demodulation. The symbols after the control region belong to the multicast channel, carrying multicast data, and are demodulated by using the multic...
