Embodiment 1

[0060] In this embodiment, the first subframe SF 0 contains user-specific control information, all non-user-specific control information is sent together, and the location of time-frequency resources and modulation and decoding methods for sending non-user-specific control information are fixed , and the terminal is known.

[0061] Such as Figure 4 As shown in (a), in SF 0, the base station sends non-user-specific control information at the time-frequency resource position of the first subframe known to the terminal according to the modulation and coding scheme known to the terminal, and the transmitted non-user-specific control information The control information includes: the time-frequency resource location used by the base station to send user-specific control information, the modulation and coding method used by the base station to send user-specific control information, and whether the base station sends user-specific control information in each subframe of the downlink...

Embodiment 2

[0071] In this embodiment, the first subframe SF 0 contains user-specific control information, the non-user-specific control information is sent in segments, and the time-frequency resource position and modulation of the first non-user-specific control information segment are sent The decoding method is fixed and known to the terminal.

[0072] Such as Figure 4 As shown in (b), in SF 0, the base station sends the first non-user-specific control information segment at the time-frequency resource position of the first subframe known to the terminal according to the modulation and coding scheme known to the terminal, so The transmitted non-user-specific control information segments include: the time-frequency resource location used by the base station to send user-specific control information, the modulation and coding method used by the base station to send user-specific control information, and whether other non-user-specific control information is included in the current subf...

Embodiment 3

[0079] In this embodiment, the first subframe SF 0 contains user-specific control information, all non-user-specific control information is sent together, and the position of the time-frequency resource for sending non-user-specific control information is not fixed, it needs to be in SF 0 to send resource allocation location information for non-user-specific control information.

[0080] Such as Figure 4 As shown in (c), in SF 0, the base station sends a description of the time-frequency used by the base station to transmit non-user-specific control information on the time-frequency resource of the first subframe known to the terminal according to the modulation and coding method known to the terminal Resource location information, that is, resource allocation location information for sending non-user-specific control information. After obtaining this information, the terminal can know the time-frequency resource location used by the base station to send non-user-specific con...

Abstract

The invention discloses a method for transmitting non-user proprietary control information in a wireless communication system. A base station transmits the non-user proprietary control information in a time zone containing the non-user proprietary control information in a downlink time slice containing a plurality of time zones; and a terminal obtains the information needed for decoding user proprietary control information according to the obtained non-user proprietary control information after obtaining and decoding the non-user proprietary control information. The invention also discloses amethod for transmitting the non-user proprietary control information, which is characterized in that the base station transmits the non-user proprietary control information in a first time zone in the downlink time slice containing a plurality of time zones with the first time zone containing user proprietary control information, and the terminal obtains the information needed for decoding the user proprietary control information according to the obtained non-user proprietary control information after obtaining and decoding the non-user proprietary control information. Users can be helped fordecoding the user proprietary control information by adopting the invention, and then the performance of the entire wireless communication system is enhanced.

Description

technical field [0001] The invention relates to information transmission technology in wireless communication, in particular to a transmission method of non-user-specific control information in a wireless communication system. Background technique [0002] In a wireless communication system, it mainly includes network entities such as mobile terminals (referred to as terminals), base stations, wireless network controllers, and core networks. Among them, base stations refer to devices that provide services to terminals, and base stations communicate with terminals through uplinks and downlinks. The downlink (or forward) refers to the direction from the base station to the terminal, and the uplink (or reverse) refers to the direction from the terminal to the base station. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] In a wireless data tran...
