Data processing method, base station and user equipment

Abstract

The invention discloses a data processing method, a base station and user equipment (UE) in order to realize UE full scheduling and HARQ (Hybrid Automatic Repeat Request) process multiplexing gain under the condition of inter-station transmission delay. The method comprises the steps as follows: a first base station uses a first HARQ process to send first downlink authorization and first downlink data to UE in a first TTI, wherein the first downlink data carries a first NDI including a first state; the first base station uses a second HARQ process to send second downlink authorization and second downlink data to the UE in a second TTI, wherein the second downlink data carries a second NDI including a second state; the first base station uses the first HARQ process to send third downlink authorization and third downlink data to the UE in a third TTI, wherein the third downlink data carries the first NDI including a third state; and the first base station uses the second HARQ process to send fourth downlink authorization and the retransmitted second downlink data to the UE in a fourth TTI according to NACK information included in a second feedback result.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a data processing method, a base station, and user equipment. Background technique [0002] The Long Term Evolution (full name in English: Long Term Evolution, English abbreviation: LTE) network is gradually developing rapidly from independent sites one by one to cooperation between sites. Common technologies include: joint transmission of two cells (English full name: jointtransmission, English abbreviation: JT), single-frequency networking (English full name: SingleFrequencyNetwork, English abbreviation: SFN), dynamic node selection (English full name: DynamicPointSelection, English abbreviation: DPS), carrier aggregation (English full name: CarrierAggregation, English abbreviation: CA), coordinated scheduling power control (English full name: Coordinated Scheduling-based Power Control, English abbreviation: CSPC), etc. [0003] An important basis for inter-...

Problems solved by technology

[0013] Step 4: Since the inter-station transmission delay is 4 milliseconds, it takes 4 milliseconds for the feedback information to be fed back to the SCC. In the 8th, 9th, and 10th milliseconds, because there is no available HARQ process, the SCC cannot schedule

Therefore, in the existing technical solution, as the inter-station transmission delay increases, the waiting time of the HARQ process will become longer, and the time that users cannot be scheduled will also be longer, which will cause a waste of air interface resources
