Description

A method and device for processing transmission power state transition time

technical field

The invention relates to mobile communication network technology, in particular to a processing method and device 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, Long-Term Evolution) / advanced long-term evolution (LTE-Advance/LTE-A, Long-Term Evolution Advance) system commercialization is increasing The requirements for technical indicators of the next-generation mobile communication technology, that is, the fifth generation mobile communication technology (5G, the 5th Generation mobile communication technology) are getting higher and higher. It is generally believed in the industry that 5G will support higher speeds (Gbps), massive links (1M/Km2), ultra-low latency (1ms), higher reliability, and 100-fold improvement in energy efficiency to support new demand changes. The ultra-low latency index in the 5G system is currently recognized as the user plane latency of 1ms.

An effective way to achieve ultra-low latency is to reduce the one-way link latency exponentially by reducing the Transmission Time Interval (TTI) of the LTE system, so as to support the characteristic requirement of the above-mentioned 1ms air interface latency. There are currently two methods for reducing TTI. One is to reduce the duration of a single OFDM symbol by expanding the subcarrier spacing of the OFDM (Orthogonal frequency-division multiplexing) system. This method is used in 5G high-frequency communication systems. Both are involved in ultra-dense networks; another method is to reduce the TTI length by reducing the number of OFDM symbols in a single TTI discussed by 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project), for example, The TTI is shortened to 1 to 7 OFDM symbols or SC-FDMA (Single-carrier Frequency-Division Multiple Access, single-carrier frequency-division multiple access) symbol length. The advantage of this method is that it can be fully compatible with the existing LTE system.

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

That is, the transmitter is always on during the conversion process. The terminal transmit power conversion time template in the following embodiments is applicable but not limited to PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) or PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) after the TTI length is shortened.

Embodiment one

Fig. 2(a) is a schematic diagram of a first time template of a demodulation reference symbol and a second time template of a data symbol according to Embodiment 1 of the present invention. As shown in Figure 2(a), the first time template provided by this embodiment is: the first state transition time of the terminal transmit power is before the start time of the current demodulation reference symbol, and the second state transition time of the transmit power is set at the current After the demodulation reference symbol end time. The continuous working time of the terminal at the rated transmit power value is equal to the duration interval of the current demodulation reference symbol.

According to the background, the transmission power state transition time is about 20 μs. When the demodulation reference symbol is 1 symbol, that is, 1/14ms is about 71 μs, then the transmission power reaches the rated value and is completed before the demodulation reference symbol starts transmission, which can save 20 μs of time is used to transmit data, and the transmit power completes the second state transition after the demodulation reference symbol starts to be transmitted, which can save another 20 μs of time.
