Problems solved by technology

[0003] In the prior art, for a cell with a large number of users, the Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel), the Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) and the Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel) Resources are limited. If the reported ACK / NACK information is parsed incorrectly, the eNodeB will allocate PDSCH resources and some uplink resources for the UE to retransmit unnecessary data, and at the same time, the channel quality of the entire cell will be reduced.
Moreover, if ACK / NACK is carried on the PUCCH channel under the existing time slot configuration, according to the existing protocol scheme, there will be ambiguity in the interpretation of ACK / NACK information, which will also lead to unnecessary waste of resources

Embodiment 1

[0059] An embodiment of the present invention provides an information processing method, such as figure 1 As shown, the method may include:

[0060] Step 101, the terminal acquires feedback status information according to PDSCH decoding.

[0061] It should be noted that a Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel) is a downlink channel for carrying user data in LTE, and all user data can be used. PDSCH is used to carry data from transport channel DSCH. In the downlink direction, the transport channel DSCH cannot exist independently, but can only exist with the forward access channel (FACH, Forward Access Channel) or the dedicated channel DCH, so the PDSCH as the carrier of the transport channel cannot exist independently.

[0062] Specifically, the terminal receives the downlink data frame sent by the base station, decodes the downlink data frame, and obtains feedback status information, wherein the feedback status information includes: acknow...

Embodiment 2

[0079] An embodiment of the present invention provides an information processing method, such as image 3 As shown, the method may include:

[0080] In step 201, the eNodeB receives the PUCCH resource sent by the terminal to obtain data before decoding, and obtains the data before decoding according to the PUCCH resource.

[0081] Specifically, the eNodeB receives the PUCCH resource sent by the terminal, demodulates the PUCCH resource, and obtains data before decoding, where the data before decoding carries the location information of the PUCCH resource and the bit information encoded and modulated by the terminal.

[0082] Step 202, the eNodeB determines the resource location of the sending identifier in the PUCCH resource location information.

[0083] Wherein, the PUCCH resource location information includes: at least two resource locations for sending identities.

[0084] Specifically, the eNodeB does not know which PUCCH resources the terminal will send information on, ...

Embodiment 3

[0092] An embodiment of the present invention provides an information processing method, such as Figure 4 As shown, the method may include:

[0093] Step 301, the terminal acquires feedback status information according to PDSCH decoding.

[0094] Specifically, the terminal receives the downlink data frame sent by the eNodeB, decodes the downlink data frame, and obtains feedback status information, where the feedback status information includes: ACK, NACK and DTX.

[0095] Step 302, the terminal searches for the PUCCH resource position information corresponding to the feedback state information in the preset correspondence, and searches for the bit information carried in the PUCCH resource corresponding to the feedback state information in the preset correspondence.

[0096] Wherein, the preset corresponding relationship includes: the corresponding relationship between feedback state information, PUCCH resource location information and bit information, and the preset correspo...

Abstract

The embodiment of the present invention discloses an information processing method, which obtains feedback state information according to PDSCH decoding; and determines the bit information and PUCCH resource position information carried by PUCCH resources according to the feedback state information and preset correspondence, wherein, the The PUCCH resource position information includes: resource positions of at least two transmission identities; and coded and modulated bit information is sent to the base station at the at least two resource positions of the transmission identities. The embodiment of the invention also discloses an information processing device, a terminal and a base station.

Description

technical field [0001] The present invention relates to TDD-LTE technology in the field of wireless communication, and in particular to an information processing method, device, terminal and base station. Background technique [0002] In the Time Division Long Term Evolution (TDD-LTE, Time Division Long Term Evolution) system, after receiving the data sent by the base station eNodeB, the terminal UE needs to notify the eNodeB of the correct ACK / wrong NACK information of the final result, and the eNodeB receives the sent data Only after the result information does it know whether to send new data or resend the wrong data. [0003] In the prior art, for a cell with a large number of users, the Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel), the Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel) and the Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel) Resources are limited. If the reported ACK / NACK informa...
