Background technique

The SAR (Specific Absorption Rate) is a parameter for measuring the intensity of the electromagnetic radiation of the human body. The standard has strict requirements on the SAR value, and the terminal cannot exceed the limit. Generally, the higher the transmission power of the terminal, the higher the SAR value, and the higher the proportion of the uplink time slot used by the terminal, the higher the SAR value. Therefore, the high power terminal (power > 23dBm) has a higher SAR value than the normal power terminal (power = 23dBm), and the uplink time slot ratio is limited in order to avoid the SAR value exceeding the regulatory requirements.

For the fifth generation (5G, 5 ^th Generation) new air interface (NR, New Radio), the high power of the terminal to circumvent the problem of the SAR value is exceeded, the terminal needs to report its supported uplink timeslot proportion at high power conditions. When the actual line slot ratio exceeds its capacity, the power level of the high power terminal is backed off to the normal power terminal. However, this method requires the terminal to always count its uplink time slot ratio in real time, which adds a lot of power consumption.

Detailed ways

To facilitate the understanding of the technical solutions of the embodiments of the present invention, the related concepts of uplink and downlink resource configuration are explained below.

In the era of Long Term Evolution (LTE), the 26dBm high-power terminal is introduced on the Time Division Duplexing (TDD), which limits the uplink and downlink time slot ratio used by the network to solve the SAR over-standard, that is, over 50. The slot ratio of the % uplink transmission cannot be used. This is feasible in the LTE network, because the uplink and downlink time slot ratio of LTE is a fixed 7 modes, as shown in Table 1 below, and the time slot ratio actually used by the network is also statically unchanged.

Table 1

However, for NR, the simple solution of LTE is no longer applicable. The reason is that the uplink and downlink ratio of NR is no longer a fixed mode, but is dynamically adjustable. As shown in Table 2 below, it includes the uplink symbol. (UL symbol, indicated by U in the table), downlink symbol (DL symbol, denoted by D in the table), flexible symbol (represented by X in the table), where flexible symbol can be used for each terminal (UE, User Equipment) Dynamically set to UL symbol or DL symbol or null symbol. Therefore, in the standard, it is no longer possible to simply limit certain types of uplink and downlink ratios to use high power. In addition, the uplink and downlink of LTE are all in units of 1 ms subframes, and NR uses symbols as the basic unit of uplink and downlink. The length of the symbol also varies with the subcarrier spacing used by the network.

Table 2

FIG. 1 is a schematic flowchart of a method for adjusting a power level of a terminal according to an embodiment of the present invention. As shown in FIG. 1 , the method for adjusting a power level of the terminal includes the following steps:

Step 101: The terminal determines an uplink transmit power and/or a first detection result of the terminal, where the first detection result refers to a distance detection result of the terminal relative to the target body.

The terminal in the embodiment of the present invention may be any device capable of communicating with a network such as a mobile phone, a tablet computer, a notebook computer, or a desktop computer. The network device in the embodiment of the present invention may be a base station, such as a gNB of a 5G system.

In the embodiment of the present invention, the target body is especially a human body, and based on the first detection result, it can be determined whether a human body approaches (or is close to) the terminal.

Step 102: The terminal determines whether to enable the first function based on the uplink transmit power of the terminal and/or the first detection result, where the first function is used to perform real-time statistics on the uplink time slot.

Step 103: If it is determined to start the first function, determine an actual line slot proportion based on the first function, and adjust a power level of the terminal based on the actual line slot proportion.

In the embodiment of the present invention, the terminal determines whether to enable the first function based on the uplink transmit power of the terminal and/or the first detection result, and may be implemented by using the following implementation manners:

Embodiment 1: The terminal determines whether to start the first function based on the uplink transmit power of the terminal. specifically:

1) If the uplink transmit power of the terminal is less than or equal to the first power threshold, the terminal does not start the first function; further, if the uplink transmit power of the terminal is less than or equal to the first power threshold, Then the power level of the terminal is maintained at the first power level. Here, the first power level may also be referred to as a high power level.

2) If the uplink transmit power of the terminal is greater than the first power threshold, the terminal starts the first function. Further, the actual line slot ratio is determined based on the first function, and when the actual line slot ratio exceeds the maximum uplink time slot ratio supported by the terminal, the power level of the terminal is adjusted to the second power. Level, the second power level being lower than the first power level. Here, the second power level may also be referred to as a low power level.

Further, after the power level of the terminal is adjusted to the second power level, if the uplink transmit power of the terminal is greater than the second power threshold, the duration reaches the first duration, and the actual row slot ratio is lower than the The maximum uplink time slot ratio supported by the terminal is adjusted, and the power level of the terminal is adjusted to the first power level.

Embodiment 2: The terminal determines whether to start the first function based on the uplink transmit power of the terminal and the first detection result. specifically:

2) if the uplink transmit power of the terminal is greater than the first power threshold, and the distance of the terminal from the target is greater than the first distance threshold, the terminal does not start the first a function; further, if the uplink transmit power of the terminal is greater than the first power threshold, and the distance of the terminal relative to the target is greater than the first distance threshold, the power level of the terminal remains Is the first power level.

3) If the uplink transmit power of the terminal is greater than the first power threshold, and the distance of the terminal relative to the target is less than or equal to the first distance threshold, the first function is started. Further, the actual line slot ratio is determined based on the first function, and when the actual line slot ratio exceeds the maximum uplink time slot ratio supported by the terminal, the power level of the terminal is adjusted to the second power. Level, the second power level being lower than the first power level. Here, the second power level may also be referred to as a low power level.

Further, after the power level of the terminal is adjusted to the second power level, 1) if the distance of the terminal relative to the target body is greater than the first distance threshold, the power level of the terminal is adjusted to the The first power level. 2) If the distance of the terminal relative to the target is less than or equal to the first distance threshold, and the uplink transmit power of the terminal is greater than the second power threshold, the duration is up to the first duration, and the actual line is The time slot ratio is lower than the maximum uplink time slot ratio supported by the terminal, and the power level of the terminal is adjusted to the first power level.

In the above two embodiments, after the power level of the terminal is adjusted, when the terminal reports the PHR to the network device, the terminal reports the current power level of the terminal to the network device, so that the network device is configured according to the terminal. The current power level schedules uplink and downlink transmission resources of the terminal.

In an embodiment, the first power threshold is determined by the terminal and reported to the network device, so that the network device determines an uplink transmit power of the terminal according to a PHR of the terminal, when the terminal When the uplink transmit power is less than or equal to the first power threshold, the network device arbitrarily schedules the uplink and downlink transmission resources of the terminal, and when the uplink transmit power of the terminal is greater than the first power threshold, The network device schedules uplink and downlink transmission resources of the terminal according to the current power level of the terminal.

In an embodiment, the first power threshold is determined by the terminal and is not reported to the network device, so that the network device schedules uplink and downlink of the terminal according to a maximum uplink time slot ratio supported by the terminal. Transfer resources. Here, after the terminal enters the connected state, the maximum uplink time slot ratio supported by the terminal is reported to the network device.

To avoid the problem of link failure caused by insufficient uplink transmit power caused by the backoff of the power level of the terminal, a certain fault tolerance mechanism is required:

Fault Tolerance Mechanism 1: The first power threshold of the terminal is less than or equal to the first power value corresponding to the second power level.

Fault-tolerant mechanism 2: After the power level of the terminal is adjusted to the second power level, the uplink transmission resource requirement is reduced by the network side and/or the uplink MCS is decreased to reduce the uplink transmit power requirement of the terminal.

The technical solutions of the embodiments of the present invention are further described below with reference to specific application examples.

Application example 1: The terminal uses its uplink transmit power as an auxiliary determining means. When the uplink transmit power is lower than a certain limit, the terminal turns off the uplink time slot real-time statistics function to save power consumption. When the uplink transmit power is higher than a certain limit, the uplink is used. The gap real-time statistics function is turned on to avoid SAR exceeding the standard.

1) After the high-power terminal enters the connected state, report the maximum uplink time slot ratio that it supports, maxUplinkDutyCycle.

2) The terminal obtains its uplink transmit power P through uplink power control calculation.

2.1) When P is less than or equal to the threshold P0, the terminal maintains its high power level and does not start the uplink time slot real-time statistics function;

2.2) When P is greater than the threshold P0, the terminal starts the real-time statistics function of the uplink time slot, and in this case, if the uplink time slot exceeds its maxUplinkDutyCycle, the terminal power level is reduced to a low power level, and the terminal reports the network together with the power level through the PHR. The network side schedules the terminal according to the latest power level of the terminal (here, the current power level is reported only once when the terminal is initially connected to the network, and then is not reported later. In the embodiment of the present invention, the terminal changes its power level in the PHR. The power level is also reported to the network when reporting.

2.3) Thereafter, if the uplink transmit power of the terminal is higher than the limit P1 for a period of time and the uplink slot statistics are lower than maxUplinkDutyCycle, the terminal is adjusted to a new high power level. The terminal reports the network through the PHR together with the power level, and the network side schedules the terminal according to the latest power level of the terminal.

Referring to FIG. 2, the threshold P0 may be implemented by the terminal autonomously without notifying the network, or may be notified by the terminal to the network to assist the network scheduling. Specifically:

Method 1: The terminal implements itself and does not notify the network.

The network is scheduled according to the terminal's maxUplinkDutyCycle capability.

Manner 2: The terminal notifies the network threshold P0.

The network derives the real-time transmit power of the terminal based on the PHR. When the uplink transmit power of the terminal is lower than the threshold, the uplink and downlink ratios of the arbitrarily scheduled terminals on the network side; when the uplink transmit power of the terminal is higher than the threshold, the uplink time slot is limited according to the latest report information of the terminal.

Application example 2: The terminal uses its uplink transmit power and distance detection as an auxiliary determination means. When the uplink transmit power is lower than a certain limit, the terminal closes the uplink time slot real-time statistics function to save power consumption, when the uplink transmit power is higher than a certain limit. However, the real-time statistics function of the uplink time slot is still closed when the human body is not close to the human body. Only when the uplink transmit power is higher than a certain limit and close to the human body, the terminal starts the uplink time slot real-time statistical function to avoid the SAR exceeding the standard.

2.2) When P is greater than the threshold P0, the terminal determines whether it is close to the human body state through the proximity sensor. If it is not close to the human body, it maintains a high power level; if it is close to the human body, it starts the real-time statistics function of the uplink time slot.

If the real-time statistics of the time slot exceeds its maxUplinkDutyCycle, the terminal power level is reduced to a low power level, and the terminal reports the network together with the power level through the PHR, and the network side schedules the terminal according to the latest low power level of the terminal.

2.3) Thereafter, 2.3.1) When the proximity sensor determines that it is not in proximity to the human body state, the terminal power level is adjusted to a high power level. The terminal reports the network through the PHR (PowerHeadRoom) together with the power level, and the network side schedules the terminal according to the latest power level of the terminal. 2.3.2) When the proximity sensor judges that it is close to the human body state, and the uplink transmit power is higher than the limit P1 for a period of time, and the uplink time slot statistics are lower than maxUplinkDutyCycle, the terminal adjusts to a new high power level. The terminal reports the network through the PHR (PowerHeadRoom) together with the power level, and the network side schedules the terminal according to the latest power level of the terminal. 2.3.3) In addition to the above two cases, the terminal is maintained at a low power level.

Method 1: The terminal implements itself and does not notify the network.

Manner 2: The terminal notifies the network threshold P0.

The network derives the real-time transmit power of the terminal based on the PHR. When the uplink transmit power of the terminal is lower than the threshold, the uplink and downlink ratio of the arbitrarily scheduled terminal of the network; when the uplink transmit power of the terminal is higher than the threshold, and after receiving the power level adjustment message reported by the terminal, the uplink is limited according to the latest report information of the terminal. Time slot.

For the above two application examples, a fault tolerance mechanism can be introduced to avoid the problem that the uplink transmit power caused by the terminal power level fallback is insufficient to cause the link to fail. specifically:

Fault Tolerance Mechanism 1: The power threshold P _{0 is} lower than the low power level of the terminal. Therefore, when the terminal retreats from the high power level to the low power level, the uplink transmit power of the terminal is still greater than the uplink transmit power required by the uplink, ensuring uplink. The link still meets the requirements.

Fault Tolerance Mechanism 2: Relying on network scheduling to reduce the uplink power demand of the terminal. The specific method is that when the terminal reports the reduced power level, the network reduces the uplink transmit power requirement of the terminal by reducing the uplink resource occupation and lowering the uplink MCS, so as to maintain the uplink connection.

In the embodiment of the present invention, determining the actual line slot proportion based on the first function may be specifically implemented by:

Assuming that the uplink time slot ratio in the first time period is counted, the time domain position of the first time period changes with time. Initially, the time domain position of the first time period is [t0, t1], T1-t0=T, the current time is changed from t0 to t1, and when the current time reaches the end time of the first time period, the time domain position of the first time period needs to be updated, that is, the first time period The time domain location is increased by at least one time unit, for example, by adding a time unit, the first time unit of the first time period is removed from the first time period, and is increased at the end of the first time period. A unit of time. Referring to FIG. 3, the time domain position of the first time period is increased by one time unit, and the time unit takes a subframe as an example, and moves the first subframe 1 in the first T0 period, and is at the first T0. Subframe n+1 is added after the last subframe n of the period, so that a second T0 period is formed, and when the current moment reaches the end of the second T0 period, the first one in the second T0 period is The sub-frame 2 is shifted out, and the sub-frame n+2 is added after the last sub-frame n+1 of the second T0 period, and so on. The duration of the current time from the initial time t0 is greater than or equal to the duration T0 of the first time period. The time domain position of the first time period changes with the change of the current time.
