Description

Method and device for processing transmission power state conversion time

Technical field

The present disclosure relates to a mobile communication network technology, and more particularly to a processing method and apparatus for transmitting power state transition time.

Background technique

With the 4th Generation mobile communication technology (4G, the 4th Generation mobile communication technology) Long Term Evolution (LTE), the Long Term Evolution (LTE-Advance/LTE-A, Long-Term Evolution Advance) system is commercially available. More and more perfect, the technical requirements for the next-generation mobile communication technology, the 5th Generation mobile communication technology (5G), are also getting higher and higher. It is widely believed in the industry that 5G will support higher speed (Gbps), massive links (1M/Km2), ultra-low latency (1ms), higher reliability, and 100 times higher energy efficiency to support new demand changes. For the ultra-low latency index in 5G systems, it is currently recognized that the user plane delay is 1 ms.

A method for effectively implementing the ultra-low latency is to reduce the unidirectional link delay by reducing the transmission time interval (TTI) of the LTE system to support the characteristic requirement of the above 1 ms air interface delay. There are two methods for reducing the TTI. One is to reduce the duration of a single OFDM symbol by expanding the subcarrier spacing of an OFDM (Orthogonal Frequency-Division Multiplexing) system. The method is for high frequency communication at 5G. Both systems and ultra-dense networks are involved; another approach is to reduce the length of TTI by reducing the number of OFDM symbols in a single TTI, as discussed by the 3GPP (The 3rd Generation Partnership Project), for example The TTI is shortened to 1 to 7 OFDM symbols or SC-FDMA (Single-Carrier Frequency-Division Multiple Access) symbol length, and the method has the advantage of being fully compatible with the existing LTE system.

In the existing LTE system, the transmission power state transition time of the terminal transmitter includes a conversion process of the transmitter power from the off state to the on state (the process takes about 20 μs) and the conversion process of the transmitter power from the on state to the off state. (The process takes about 20μs). As the TTI length is shortened, especially when the TTI is equal to 1 symbol, ie 1/14 ms, 40 μs will occupy approximately 60% of the length of the TTI. Therefore, there is a need to provide a processing method for transmitting power conversion time to meet the needs of ultra-low latency scenarios.
