Embodiment 1

[0188] The RN uses the R-PUCCH format 1 channel structure under normal CP to carry ACK / NACK feedback information, and the eNB configures the relevant parameters for the RN as follows: and Correspondingly, the RN can obtain the relevant parameters of the R-PUCCH resource according to the same method as the PUCCH resource configuration parameter calculation, as follows:

[0189] m=3

[0190] n PRB = N RB UL - 2 for slot 0 1 for slot 1

[0191] n ′ ( n s ) = 7 ...

Embodiment 2

[0214] RN adopts R-PUCCH format 1 channel structure 2 under normal CP to carry ACK / NACK feedback information, and eNB configures relevant parameters for RN as follows: Other parameters can be obtained in turn as follows:

[0215] m=4

[0216] n PRB = 2 for slot 0 N RB UL - 3 for slot 1

[0217] n ′ ( n s ) = 16 for slot 0 12 for slot ...

Embodiment 3

[0239] The RN uses the R-PUCCH format 1 channel structure under the extended CP to carry ACK / NACK feedback information, and the eNB configures relevant parameters for the RN as follows: Then other parameters can be obtained in sequence as follows:

[0240] m=6

[0241] n PRB = 3 for slot 0 N RB UL - 4 for slot 1

[0242] n ′ ( n s ) = 6 for slot 0 4 ...

Abstract

The invention discloses a method and a device for processing hybrid automatic repeat request (HARQ) uplink feedback information for a backhaul link. The device comprises an HARQ uplink feedback information generation module, a modulation module, a frequency domain expansion module and a time domain expansion module, wherein the HARQ uplink feedback information generation module is used for generating a piece of feedback information for received data, and coding to obtain a feedback information sequence, or generating a plurality of pieces of feedback information for a plurality of pieces of received data, coding to obtain a plurality of feedback information sequences, and multiplexing the plurality of feedback information sequences to obtain a multiplexed feedback information sequence. By the method and the device, the aim that a relay node (RN) loads the HARQ uplink feedback information to a relay-physical uplink control channel (R-PUCCH) and transmits the HARQ uplink feedback information to an evolved node B (eNB) can be effectively fulfilled, the transmission efficiency of the uplink feedback information of the backhaul link can be improved by fully using the channel condition of the backhaul link.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a processing method and device for Hybrid Automatic Repeat request (HARQ) uplink feedback information (ACK / NACK) of a backhaul link (Backhaul Link). Background technique [0002] Relay (Relay) technology, as an emerging technology, has attracted more and more attention, and is regarded as a key technology of B3G / 4G. Since future wireless communication or cellular systems require perfect network coverage and support for higher rate transmission, this poses new challenges to wireless communication technology. At the same time, the cost of system construction and maintenance is more prominent. With the increase of transmission rate and communication distance, the problem of battery energy consumption has become more prominent, and future wireless communication will use higher frequencies, resulting in more serious path loss attenuation. Through the relay technology,...
