Description
Technical Field
The present invention relates to mobile communication network technologies, and in particular, to a method and an apparatus for processing transmit power state transition time.
Background
With the increasing improvement of the fourth Generation mobile communication technology (4G), Long Term Evolution (LTE, Long-Term Evolution)/Long Term Evolution advanced (LTE-Advance/LTE-a, Long-Term Evolution Advance) system, the requirement of the technical index for the next Generation mobile communication technology, i.e., the fifth Generation mobile communication technology (5G) is higher and higher. It is widely recognized in the industry that 5G will support higher rates (Gbps), massive links (1M/Km2), ultra-low latency (1ms), higher reliability, hundreds of times energy efficiency increase, etc. to support new demand changes. For the index of ultra-low delay in the 5G system, it is currently accepted that the user plane delay is 1 ms.
One method for effectively achieving ultra-low latency is to reduce the one-way link latency by multiple times by reducing the Transmission Time Interval (TTI) of the LTE system, so as to support the characteristic requirement of the 1ms air interface latency. At present, there are two methods for reducing 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, and the method is involved in both a 5G high-frequency communication system and an ultra-dense network; another method is to reduce The TTI length by reducing The number of OFDM symbols in a Single TTI, as discussed in 3GPP (The 3rd Generation Partnership Project), for example, shortening The TTI to 1-7 OFDM symbols or SC-FDMA (Single-Carrier Frequency-Division Multiple Access) symbol length, which has The advantage of being fully compatible with existing LTE systems.
In the existing LTE system, the transition time of the transmission power state of the terminal transmitter includes a transition process of the transmitter power from an off state to an on state (the process takes about 20 μ s) and a transition process of the transmitter power from an on state to an off state (the process takes about 20 μ s). As the TTI length shortens, especially when the TTI equals 1 symbol, 1/14ms, 40 μ s will occupy approximately 60% of the TTI length. Therefore, a processing method for providing transmit power conversion time is needed to meet the requirements of ultra-low latency scenarios.

S12, judging whether the sending condition is satisfied at present, if so, acquiring a corresponding time template;
wherein the time template is the variation of the transmitting power of the transmitter in the time domain. The transmitter performs state conversion according to the time template. For example, the transmitter may be configured according to a time template from off to on, on to off, at a nominal power, varying from one transmit power to another, and so forth. The time template may be plural, and different time templates may be set in different cases.
Wherein the time pattern comprises a first time pattern for transmitting the demodulation reference symbols and a second time pattern for transmitting the data symbols.
And S13, transmitting the data symbols and the demodulation reference symbols by using the time template.
In an embodiment of the present invention, the first time template is:
setting a transmission power first state transition time before the transmission duration starting time of the demodulation reference symbol, and setting a transmission power second state transition time after the transmission duration ending time of the demodulation reference symbol;
or the sum of the transmission power first state transition time and the time of continuous operation at the rated transmission power is equal to the transmission duration of the demodulation reference symbol, and the transmission power second state transition time is set after the end time of the transmission duration of the demodulation reference symbol;
further, at least one of the transmission power first state transition time and the transmission power second state transition time is included in the transmission duration of the current demodulation reference symbol.
In an embodiment of the present invention, the second time template is:
the first state transition time of the transmitting power is set before the starting time of the data symbol, and the second state transition time of the transmitting power is set after the ending time of the data symbol;
or, the sum of the transmission power first state transition time and the time that the transmitter continuously operates at the rated transmission power is equal to the transmission duration of the data symbol, and the transmission power second state transition time is set after the end time of the transmission duration of the data symbol;
further, at least one of the transmit power second state transition time and the transmit power second state transition time is included in a transmission duration of the current data symbol.
Wherein the first state transition time of the transmission power is as follows:
a transition time of the transmission power from an off state to an on state; or a transition time of the transmit power from the first on state to the second on state.
Wherein the second state transition time of the transmission power is:
a transition time of the transmit power from an on state to an off state; or a transition time of the transmit power from the first on state to the second on state.
In an embodiment of the present invention, a transition time of the transmission power from the first on state to the second on state is: the transmission power remains on for a transition time from a first on state to a second on state. I.e. the transmitter is always on during the conversion. The terminal transmit power conversion time template in the following embodiments is applicable to, but not limited to, a PUSCH (Physical Uplink Shared Channel) or a PUCCH (Physical Uplink Control Channel) with a shortened TTI length.
Example one
The present embodiment provides a first time pattern of demodulation reference symbols and a second time pattern of data symbols for the terminal when the transmission duration of demodulation reference symbols is equal to one symbol and the transmission duration of data symbols is equal to two symbols.
Fig. 2(a) is a schematic diagram of a first time pattern of demodulation reference symbols and a second time pattern of data symbols according to a first embodiment of the present invention. As shown in fig. 2(a), the first time template provided by this embodiment is: the terminal transmission power first state transition time is before the current demodulation reference symbol starting time, and the transmission power second state transition time is set after the current demodulation reference symbol ending time. The terminal operates continuously at the nominal transmission power value for a time equal to the duration interval of the current demodulation reference symbol.
As shown in fig. 2(a), the second time template provided by this embodiment is: the terminal transmission power first state transition time is completed before the starting time of the transmission duration of the current data symbol, namely the rated transmission power value of the terminal transmitter is reached at the beginning of TTI, and the terminal transmission power second state transition time is the power transition started at the end of the transmission duration of the current data symbol, and the time of the terminal continuously working at the rated transmission power value is equal to the transmission duration of the current data symbol.
In the background, the transmit power state transition time is about 20 μ s, when the demodulation reference symbol is 1 symbol, i.e., 1/14ms is about 71 μ s, then 20 μ s of time is saved for transmitting data when the transmit power reaches the nominal value and is completed before the demodulation reference symbol starts to be transmitted, and 20 μ s of time is saved when the transmit power completes the second state transition after the demodulation reference symbol starts to be transmitted. This is a very effective way to improve the data transmission efficiency for a duration of only 71 μ s in total for the transmission duration of the demodulation reference symbols.
Similarly, the transmit power conversion time state of the data symbol is set outside the transmission duration of the data symbol, and the duration of the transmission duration of the current data symbol is used to transmit data, which is a very effective way to improve the data transmission efficiency for data transmission.
The time pattern of the data symbols shown in fig. 2(a) is applicable not only to 2 symbols but also to 1 or 3 symbols or the like of the data symbols.
As shown in fig. 2(a), the power conversion of the terminal transmission power does not occupy any time for carrying data, so that the data transmission efficiency can be effectively improved.
Example two
The present embodiment provides a first time pattern of demodulation reference symbols and a second time pattern of data symbols for the terminal when the transmission duration of demodulation reference symbols is equal to one symbol and the transmission duration of data symbols is equal to two symbols. Fig. 2(b) is a schematic diagram of a first time template of demodulation reference symbols and a second time template of data symbols according to a second embodiment of the present invention. As shown in fig. 2(b), the first time template and the second time template of the present embodiment are respectively:
the terminal transmitting power of the first time template, the first state transition time and the second state transition time are both completed outside the transmission duration of the demodulation reference symbols;
the second time template is: the sum of the first state transition time of the transmission power and the time that the transmitter continuously operates at the rated transmission power is equal to the transmission duration of the current data symbol, and the second state transition time of the transmission power is performed after the end time of the transmission duration of the current data symbol, namely after the transmission duration of the current data symbol.
The processing manner of the second time template can make the interference generated in the process of converting the transmission power in the transmission duration of different data symbols exist in a Cyclic Prefix (CP) at the beginning of the transmission duration of each data symbol, and the influence of the interference can be reduced to a certain extent.
EXAMPLE III
The present embodiment provides a first time pattern of demodulation reference symbols and a second time pattern of data symbols for the terminal when the transmission duration of demodulation reference symbols is equal to one symbol and the transmission duration of data symbols is equal to two symbols. Fig. 2(c) is a schematic diagram of a first time pattern of demodulation reference symbols and a second time pattern of data symbols according to a third embodiment of the present invention. As shown in fig. 2(c), when the terminal transmit power of the first time template, the first state transition time and the second state transition time are both completed outside the demodulation reference symbol transmission duration:
the second time template is: the sum of the time during which the transmitter operates continuously at the nominal transmission power and the second state transition time of the transmission power is equal to the transmission duration of the current data symbol, and the first state transition time of the transmission power is completed before the transmission duration of the current data symbol begins, i.e. the nominal transmission power value of the terminal transmitter has been reached at the beginning of the transmission duration of the data symbol.
Such a processing of the second time template may reduce the impact of the first state transition time on the effective data carrying time.
Example four
The present embodiment provides a first time pattern of demodulation reference symbols and a second time pattern of data symbols for the terminal when the transmission duration of demodulation reference symbols is equal to one symbol and the transmission duration of data symbols is equal to two symbols. Fig. 2(d) is a schematic diagram of a first time pattern of demodulation reference symbols and a second time pattern of data symbols according to a fourth embodiment of the present invention. As shown in fig. 2(d), when the terminal transmit power of the first time template, the first state transition time and the second state transition time are both completed outside the demodulation reference symbol transmission duration:
the second time template is: the sum of the transmission power first state transition time, the time that the transmitter continuously operates at the rated transmission power and the transmission power second state transition time is equal to the transmission duration of the current data symbol.
The second time pattern of data symbols shown in fig. 2(d) may maximize the reduction of power-up and/or power-down interference between transmission durations of different data symbols, between different users, and between different information.
