In an era of informationalization, we are increasingly relying on mobile phones for our work, travel, purchase and recreation. In particular, when outside, when mobile phones show a low level of electricity, the minds of the filers are overstretched and generally feel insecure.

However, the characteristics of the 5G bandwidth, multi-day wires, etc., while increasing speed rates, have also led to a significant increase in the consumption of chickens and radio frequency, which has resulted in the consumption of 5G handicrafts more quickly, often not over a day, with few mobile phones remaining.

Upgrading

The simplest way of renewing the capacity of mobile phones is, of course, to increase the capacity of batteries, but until a breakthrough in battery technologies is made, the capacity of the cells will be increased and the number of mobile phones will be much greater, contrary to the goal of light-handling.

How can 5G break down on end-of-pipe electricity, apart from increasing cell capacity to upgrade mobile phones?

The screen is a consumable household of mobile telephone power, while the cell operator consumes power from the lowering of mobile screens: automatically adjusts the screen update rate and the “going model”; on the other hand, starts the smart network option. The so-called smart network option is to ensure the renewal of mobile phones by changing 5G and 4G at all times depending on user needs. For example:

The provincial power strategies described above are essentially: the automatic closure of the 5G network in the absence of large-scale flow operations, for example, only in view of paper, and the use of 4G networks to transmit data, thus allowing mobile phones to become more departmental.

However, the 5G network, which is not used as an end-of-charge, is certainly not the best, after all, the more expensive 5G bags, the more expensive 5G mobile phones, have been purchased, and I have been told: or 4 G bars! Less appropriate ~

Is it going?

In fact, end-of-pipe power is not only available from the end itself, but the optimization of network configuration on the base station is equally effective.

UAI (UE Assistance Information, user equipment support information), i.e. end-of-pipe information. The introduction of UAI is an accurate and effective means of obtaining terminal requirements for the base station.

UAI telephony programme: the end, in order to reduce its own energy consumption, will place the desired network on the base station to help it better understand the reality of each terminal. The base station will adjust its resource allocation to help end-users, as recommended by the terminal.

UAI was introduced in 3GPP R15 for end-of-life protection. The significant increase in the efficiency of the 5G system has resulted in an end-to-earth hazard, which, when the end-point is tested for his or her own heat, offers to inform the base station of thermal auxiliary information and adjusts the terminal configuration (e.g., reduced bandwidth) according to the supporting information, thereby avoiding the end-of-heat problem.

In order to further reduce end-use, 3GPP R16 added UAI, based on energy conservation, to support end energy efficiency. The end-of-service operation may result from a smaller volume of operations or a limited end power supply, with a view to maximizing the savings of the terminal through a reduced configuration, leading to the introduction of energy-saving support information to the base station and targeted adjustment of the base station to reduce end energy consumption. The process is as follows:

The base station provides the terminal UE capability search information.

The terminal response base station informs it of the energy efficiency capabilities it supports.

The base station, through RRC (Radio Resource Control, wireless resource control), is equipped with different energy efficiency configurations.

When the volume of operations is smaller or restricted, the terminal is reported to UAI on the base station and carries recommended energy-saving configurations.

The base station is subject to a targeted adjustment based on the end-up recommended configuration to save energy at the end.

When energy efficiency is no longer required, the terminal is reported to UAI and the base station is reconfigured.

RRC relayed information at the base station to reconfigure the terminal and improve the operational speed of the terminal.

In UAI, the end-loaded to the base station, the following information is used for end-use.

Thermally assisted information: maximum bandwidth, maximum auxiliary waves, largest MIMO layers.

Energy-saving support information: DRX (Discontinuous Reception, non-continuous) configuration, maximum bandwidth, maximum auxiliary wave, maximum MIMO layer, minimum interval between movement control and RRC status.

UAI information-saving mechanisms are as follows:

Non-continuous reception, i.e., end-cycle testing and receipt of PDCCH, reduces the end-wave time.

Energy efficiency with small bandwidth BWP (Bandwidth Part, partial bandwidth) was replaced with smaller bandwidth BWP. Compared to fixed work in 100 MHz bandwidth, swaps to small bandwidth BWP, lower sampling frequency and reduced end-use consumption.

While Pcells (main subdistricts) and Scell (subsidiary subdistricts) can transmit data simultaneously to the end in order to increase the speed of data transmission, the ends will also be monitored on a continuous basis in the absence of data transmission in Scell, leading to increased end-uses. Therefore, when operations are low, they can be used to drive part of the auxiliary to reduce end-use.

The number of MIMO skylines adjusted will be temporarily closed, and the number of daylines receiving data will be reduced.

The cross-currency movement control channel PDCCH and the operational channel PDSCH are not deployed at the same time. The end blindness screening, after receiving the PDCCH control signal, does not immediately declassify the operational data in PDSCH, but re-codes after the interval of the directed movement control, in order to save the cost of the de code when data are not transmitted.

To instruct end-users to enter into energy-saving conditions. Depending on the state of energy savings reported at the end, the station, in conjunction with its own strategic decision-making, releases the terminal to RRC_INACTIVE (to activate) or RRC_IDLE (inactive).

5G NR ends with 3 types of RRC status: CONNECTED, IDLE, INACTIVE.

CONNECTED: connectivity, links between terminals and base stations, base stations and core networks are established and data can be transmitted at any time, but the terminal is expensive.

IDLE: Occidental, terminal and base station, base station and core network
