Embodiment Construction

[0100] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0101] like figure 1 As shown, an embodiment of the present invention provides a method for transmitting diversity in a multi-antenna communication system, where the multi-antenna communication system includes N antenna ports, and the method includes:

[0102] Step 21, determining the pilot sequence to be transmitted for each antenna port;

[0103] Step 22, respectively mapping the pilot sequences to be transmitted of each antenna port to the resource elements RE contained in the pilot symbols of the target subframe, so that the N antenna ports multiplex the pilot symbols of the target subframe;

[0104] Step 23, on the target subframe, each antenna port transmits the pilot sequence to be transmitted on the RE of the pilot symbol mapped to the pilot seq...

Abstract

The invention provides a diversity emission method and apparatus in a multi-antenna communication system. The method includes steps: determining a to-be-transmitted pilot frequency sequence of each antenna port; and respectively mapping the to-be-transmitted pilot frequency sequence of each antenna port to a resource element (RE) included by a pilot frequency symbol of a target sub-frame to enableN antenna ports reuse the pilot frequency symbol of the target sub-frame, wherein each antenna port respectively emits the to-be-transmitted pilot frequency sequences on the REs mapped to the to-be-transmitted pilot frequency sequence of the antenna port, of the pilot frequency symbol. According to embodiments of the method and apparatus, the to-be-transmitted pilot frequency sequence of each antenna port is respectively mapped to the resource element (RE) included by the pilot frequency symbol of the target sub-frame so that reuse of the pilot frequency symbol for different antenna ports isrealized; besides, the transmission of the pilot frequency sequence of each antenna port can satisfy the characteristic of a single carrier so that the goal of multi-antenna port transmission is achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for transmitting diversity in a multi-antenna communication system. Background technique [0002] In LTE Rel-14 V2X technology, the terminal UE includes two channels when transmitting data, one control channel PSCCH is used to transmit scheduling assignment information (SA, Scheduling Assignment); the other data channel PSSCH is used to transmit data information (Data). The receiving end first detects the SA information carried in the control channel, so as to receive the data information according to the received control information. [0003] In LTE Rel-14 V2X technology, there are two resource selection modes: [0004] One is the way that the terminal UE selects resources spontaneously. The UE selects idle resources through the perception method in the system configuration or pre-configured V2X resource pool; the other is the base station-ass...
