Embodiment 1

[0209] Preferred embodiment 1: includes 3 sub-embodiments.

Embodiment 11

[0211] This embodiment assumes LTE-IOT uplink transmission. Figure 5 It is a schematic diagram of the preferred implementation of the timing relationship on the base station side according to the present invention Figure 1 ,Such as Figure 5As shown, in a period of time domain resources, the first resource unit ReEl 1, the third resource unit ReEl 3, the second resource unit ReEl 2, the fourth resource unit ReEl 4, and the first resource unit ReEl1 increase with time. The base station adopts FDMA mode and SC-OFDMA mode to receive and process data on ReEl 1 and ReEl 2 respectively. ReEl 3 and ReEl 4 are guard intervals, and the time lengths are T3 and T4 respectively. The guard interval design mainly considers the switching delay between different multiple access modes of the base station and the timing requirements of uplink transmission. In this embodiment, T3>T4. The reason is that T3 takes into account the handover delay and timing. T4 only considers the switching dela...

Embodiment 12

[0213] This embodiment assumes that on a period of time domain resources, Figure 6 It is a schematic diagram of the preferred implementation of the timing relationship on the base station side according to the present invention Figure II ,Such as Figure 6 As shown, the increase over time is the first resource unit ReEl 1, the third resource unit ReEl 3, the second resource unit ReEl 2, the fourth resource unit ReEl 4, and the first resource unit ReEl 1. The base station adopts time domain code division mode and SC-OFDMA mode to receive and process data on ReEl 1 and ReEl 2 respectively. ReEl 3 and ReEl4 are guard intervals, and the time lengths are T3 and T4 respectively. The design of the guard intervals is mainly to consider the switching delay between different multiple access modes and timing requirements. T3=T4 in this embodiment. T3 and T4 take into account the switching delay from ReEl1 to ReEl 2 and from ReEl 2 to ReEl 1, as well as timing requirements. In this ...

Abstract

The invention provides a data processing method based on a radio access technology (RAT) and transmission nodes. The method comprises steps: a first transmission node selects a radio access technology (RAT) according to a specific rule, wherein the specific rule comprises at least one selected from a coverage grade, a frequency domain bandwidth, a resource unit type, a transmission mode, pre-configuration of the first node and the capability of a second transmission node to select the RAT; the RAT comprises at least one selected from a multi-access mode, a modulation mode, a subcarrier interval and the maximum carrier number for bearing data; the capability of the second transmission node is defined by the RAT supported by the second transmission node; and the first transmission node carries out data receiving or transmission on a radio resource unit corresponding to the RAT according to the selected RAT. The problem of integrating different RATs is solved, different design requirements are met, and different RATs are compatible.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data processing method and a transmission node based on wireless access technology. Background technique [0002] In a wireless communication system, different users use multiple access technology to share wireless communication resources. Common multiple access technologies include Frequency Division Multiple Access (FDMA for short), Time Division Multiple Access (TDMA for short), and Code Division Multiple Access multiple access (CDMA). Code Division Multiplexing Access (CDMA for short), Orthogonal Frequency Division Multiplexing Access (OFDMA for short), Single Carrier Orthogonal Frequency Division Multiple Access (Single Carrier -Orthogonal Frequency Division Multiplexing Acess, referred to as SC-OFDMA). [0003] In the Long Term Evolution (LTE for short) system of the Release-12 version, SC-OFDMA and OFDMA technologies are used for uplink and downlink respectively. In...
