Embodiment 1

[0157] Assuming that UE1 is an R11 user, the network side configures a set of continuous subframes N (N ≥ 1) for UE1 through high-level signaling or a fixed method in the standard to indicate that UE1 has N consecutive subframes after a trigger Used to feed back the CSI of one or more nodes. When the network side needs UE1 to perform feedback on the PUSCH, the network side triggers UE1 to send information on n The CSI of one or more nodes is fed back on the +k (k≥4) subframe and subsequent N-1 consecutive subframes. UE1 obtains the continuous subframe number N (N≥1) of a set of PUSCH trigger feedback by receiving high-level signaling sent by the network side or configured in a fixed way in the standard, which is used to feed back one or more consecutive subframes after a trigger. Node's CSI. UE1 detects 1-bit signaling in the uplink and / or downlink control signaling in the physical downlink control channel sent by the network side on the nth (n≥0) subframe and triggers UE1 t...

[0159] Assuming that UE1 is an R11 user, the network side configures a set of continuous subframes N (N ≥ 1) for UE1 through high-level signaling or a fixed method in the standard to indicate that UE1 has N consecutive subframes after a trigger Used to feed back the CSI of one or more nodes. The 2-bit signaling in the uplink and / or downlink control signaling in the physical downlink control channel on the nth (n≥0) subframe on the network side triggers UE1 on and after n+k (k≥4) subframes The CSI of one or more nodes is fed back in consecutive N-1 subframes, wherein 1 bit of the 2 bits is used to indicate whether to trigger CSI feedback of the PUSCH, and 1 bit is used to indicate whether to frequency hop.

[0161]Assuming that UE1 is an R11 user, the network side configures UE1 a set of continuous subframe number N (N≥1) for PUSCH trigger feedback through high-level signaling or a fixed method in the standard to indicate UE1 After one trigger, N consecutive subframes are used to feed back the CSI of one or more nodes. M (M≥3) bit signaling in the uplink and / or downlink control signaling in the physical downlink control channel on the nth (n≥0) subframe on the network side triggers UE1 to operate at n+k (k≥4) The CSI of one or more nodes is fed back on the subframe and subsequent N-1 consecutive subframes, where 1 bit of the M bits is used to indicate whether to trigger the CSI feedback of the PUSCH, and the M-1 bit is used to indicate whether to frequency hop and / or Or the candidate frequency hopping pattern used for frequency hopping.

Abstract

The invention provides a feedback configuration method, a device and a system based on physics uplink sharing information channel. The method includes the steps: a network side informs a receiving side on one or a plurality of sub-frames on a physics uplink sharing information channel to utilize correct frequency hopping modes based on a physics source block and/or a physics source block to feed back one or multiple nodal points of channel state information (CSI) through a high-level signaling or a standard centre fixed mode or a physics signaling; one or the multiple nodal points of the CSI are received; and one or the multiple nodal points of the CSI are detected. The feedback configuration method, the device and the system based on physics uplink sharing information channel guarantee the physical uplink control channel (PUCCH) capacity and precision of the CSI under an existing standard.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a feedback configuration method, device and system based on a physical uplink shared channel. Background technique [0002] The Long Term Evolution (LTE for short) system is preparing to study the R 11 technology after several versions of R 8 / 9 / 10. At present, some R8 products are gradually starting to be commercialized, and R9 and R10 are subject to further product planning. [0003] After going through the stages of R 8 and R 9, R 10 added many new features on the basis of the first two, such as demodulation reference signal (Demodulation Reference Signal, referred to as DMRS), channel state information reference signal (Channel State Information Reference Signal, referred to as CSI-RS) and other pilot features, 8-antenna support and other transmission and feedback features, etc., especially inter-node interference cancellation enhancement (ehanced Inter-Cell Interference Ca...
