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However, for the new wireless (NR, New Radio), the simple solution of LTE is no longer applicable, because the uplink and downlink ratio of NR is no longer a fixed mode, but is dynamically adjustable, as shown in Table 2 below.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 an uplink symbol (UL symbol, represented by U in the table), a downlink symbol (DL symbol, represented by D in the table), and a flexible symbol (indicated by X in the table), wherein the flexible symbol can be for each The UE (User Equipment) is dynamically set to a UL symbol or a DL symbol or an empty 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. As can be seen from the above, in order to avoid the problem of high power terminal SAR exceeding the standard, it is necessary to find a new solution.

Table 2

FIG. 1 is a schematic flowchart 1 of a resource configuration method according to an embodiment of the present invention. As shown in FIG. 1 , the resource configuration method includes the following steps:

Step 101: The terminal records the SAR cumulative value corresponding to the uplink transmission in the first time range in the first time period.

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, after the terminal enters the connected state, the terminal starts to implement the solution of the embodiment of the present invention.

In the embodiment of the present invention, the first time period is a time window, and the length of the time window is assumed to be T0. Initially, the start time of the time window is t0, and the end time is t1, where t1-t0=T. In an embodiment, the first time range in the first time period is a time range before the current time in the first time period, and the second time range in the first time period is the first time range The time range after the current time in the time period, assuming that the current time is t and t0 ≤ t ≤ t1, the first range is [t0, t], and the second time range is [t, t1].

In the embodiment of the present invention, the terminal records the SAR cumulative value corresponding to the uplink transmission in the first time range in the first time period, and is implemented in the following manner: 1) the terminal records the first time in the first time period The corresponding transmit power of the uplink transmission in the range; 2) the terminal determines the first time range based on a correspondence between the transmit power and the SAR value, and a transmit power corresponding to the uplink transmit in the first time range The SAR cumulative value corresponding to the uplink transmission.

In the embodiment of the present invention, the correspondence between the transmission power and the SAR value is closely related to the antenna design of the terminal and the posture of the human holding terminal. Therefore, the actual transmission power of the terminal and the different holding state are required to be tested. The SAR value correspondence list in a certain time (such as the symbol length) is obtained, for example, the correspondence between the transmission power and the SAR value in the posture of the human hand close to the terminal (P-> SAR Hand), and the transmission power in the posture of the head hand close to the terminal. Correspondence with SAR values (P->SAR Head) and so on. The corresponding relationship lists are stored in the terminal, and the correspondence list is as shown in Table 3:

table 3

The terminal needs to detect whether the holding state is in a Hand state, a Head state or other state, and the terminal records the transmitting power corresponding to the uplink transmission from the time t0 to the current time t in real time, and then, the terminal The SAR cumulative value is calculated based on the corresponding relationship between the transmit power and the SAR value in the corresponding grip state. It is assumed that the SAR cumulative value corresponding to the uplink transmission of the terminal at [t0, t] is SAR(1), and the calculation formula of SAR(1) is :

If n symbols are included between [t0,t], the calculation formula of SAR1 is

It is worth noting that since the current time t is varied, the first time range and the second time range also vary.

Step 102: The terminal determines, according to the uplink and downlink configuration information, a SAR cumulative value corresponding to the uplink symbol in the second time range in the first time period, where the first time period includes the first time range and the The second time range is described.

In the embodiment of the present invention, the terminal may obtain the uplink and downlink configuration information based on the configuration of the network or the preset information. As shown in Table 2 above, the uplink and downlink configuration information may be any of the 62 formats.

In the embodiment of the present invention, the terminal determines, according to the uplink and downlink configuration information, the SAR cumulative value corresponding to the uplink symbol in the second time range in the first time period, which is implemented by: 1) the terminal is based on the upper and lower Determining, by the row configuration information, the number of uplink symbols in the second time range in the first time period; 2) the first SAR value corresponding to the first transmit power, and the second time range And determining, by the number of uplink symbols, a SAR cumulative value corresponding to the uplink symbol in the second time range, where the first transmit power is greater than or equal to the first power value.

It should be understood that the duration of the first time period is in units of time units, for example, the length T0 of the first time period is equal to N time units, N is a positive integer, and the time unit is a subframe or a time slot. , or sTTI. It is assumed that the second time range [t, t1] includes M time units, M ≤ N, and based on the uplink and downlink configuration information, it can be determined that each time unit includes n uplink symbols, and the number of uplink symbols in the second time range is It is M×n. In addition, the first transmit power is the maximum transmit power of the terminal, and the first SAR value corresponding to the first transmit power is, for example, a SAR value (SAR_23) at a transmit power of 23 dBm, based on which the uplink symbol in the second time range corresponds. The calculation formula of the SAR cumulative value SAR(2) is: M×n×SAR_23.

Step 103: The terminal determines the SAR margin of the first time period based on the SAR cumulative value corresponding to the uplink transmission in the first time range and the SAR cumulative value corresponding to the uplink symbol in the second time range. Transmitting the SAR margin of the first time period to the network device, to adjust, by the network device, the uplink resource in the second time range according to the SAR margin of the first time period.

In the embodiment of the present invention, the terminal determines, according to the SAR cumulative value corresponding to the uplink transmission in the first time range, the SAR cumulative value corresponding to the uplink symbol in the second time range, and the target SAR threshold value. The SAR margin of the first time period.

Based on this, the SAR margin of the first time period can be determined by the following formula: SAR_target-(SAR(1)+SAR(2)), where SAR(1) is the uplink transmission in the first time range. Corresponding SAR cumulative value, SAR(2) is the SAR cumulative value corresponding to the uplink symbol in the second time range, and SAR_target is the target SAR threshold value.

The terminal monitors the SAR margin in real time, and determines that the SAR margin of the first time period is less than or equal to the first threshold (for example, 0), and sends the SAR margin of the first time period to the network device, where the network device is located. In the second time range (ie [t, t1]), the flexible symbols are not used for uplink transmission, and the maximum transmit power is backed off to 23 dBm.

In the embodiment of the present invention, the time domain position of the first time period is not fixed. Initially, the time domain position of the first time period is [t0, t1], t1-t0=T, current time. 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 time domain position of the first time period 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 a time unit is added at the end of the first time period. Referring to FIG. 2, 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.

Based on this, when the time domain position of the first time period changes with the change of the current time, the first time range and the second time range of the first time period also change, based on the above steps 101-103 And updating the SAR margin of the first time period, and sending the updated SAR margin of the first time period to the network device, to use the updated SAR margin of the first time period by the network device Adjusting uplink resources in the second time range. Taking FIG. 2 as an example, suppose that the current time T0 ≤ t ≤ 2 × T0, the SAR accumulation amount corresponding to the uplink transmission in the first T0 period is SAR (s1), and the uplink of the first subframe 1 in the first T0 period The SAR cumulant corresponding to the transmission is SAR (s2), and the SAR cumulant corresponding to the uplink symbol of the subframe n+1 following the last subframe n of the first T0 period is SAR (s3), and the updated The SAR margin for a time period is: SAR(s1)-SAR(s2)+SAR(s3), where SAR(s1) and SAR(s2) can be calculated by the correspondence shown in Table 3, SAR (s3) It can be calculated by using the uplink and downlink configuration information and the first SAR value corresponding to the first transmit power (such as SAR_23). If the subframe n+1 includes n uplink symbols, then SAR(s3)=n×SAR_23. When the SAR margin of the second T0 cycle (ie, the updated first T0 cycle) is less than or equal to the first threshold, the second T0 cycle (ie, the updated first T0 cycle) The SAR margin is sent to the network device, and the network device does not need to perform uplink transmission in the second time range (ie, subframe n+1), and the maximum transmit power is backed off to 23 dBm.

FIG. 3 is a schematic flowchart 2 of a resource configuration method according to an embodiment of the present invention. As shown in FIG. 3, the resource configuration method includes the following steps:

Step 301: The network device records the SAR cumulative value corresponding to the uplink transmission of the terminal in the first time range in the first time period.

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, after the terminal enters the connected state, the network device starts to implement the solution of the embodiment of the present invention.

In the embodiment of the present invention, the network device records the SAR cumulative value corresponding to the uplink transmission in the first time range in the first time period, and is implemented by: 1) the network device records the first time period in the first time period. The corresponding transmit power of the uplink transmission in a time range; 2) the network device determines the first part based on a correspondence between the transmit power and the SAR value, and a transmit power corresponding to the uplink transmit in the first time range The SAR cumulative value corresponding to the uplink transmission in a time range.

In the embodiment of the present invention, the correspondence between the transmission power and the SAR value is closely related to the antenna design of the terminal and the posture of the human holding terminal. Therefore, the actual transmission power of the terminal and the different holding state are required to be tested. The SAR value correspondence list in a certain time (such as the symbol length) is obtained, for example, the correspondence between the transmission power and the SAR value in the posture of the human hand close to the terminal (P-> SAR Hand), and the transmission power in the posture of the head hand close to the terminal. Correspondence with SAR values (P->SAR Head) and so on. The corresponding relationship lists are stored in the terminal, and the terminal reports the corresponding relationship list to the network device.

The network device records the transmit power corresponding to the uplink transmission from the time t0 to the current time t in real time, and then the network device calculates the SAR cumulative value based on the corresponding relationship between the transmit power and the SAR value in the corresponding grip state, assuming that the terminal is at [t0 The cumulative SAR of the uplink transmission of t, t] is SAR(1), and the calculation formula of SAR(1) is:

If n symbols are included between [t0,t], the calculation formula of SAR1 is

Step 302: The network device determines, according to the uplink and downlink configuration information, a SAR cumulative value corresponding to the uplink symbol in the second time range in the first time period, where the first time period includes the first time range and The second time range.

As shown in Table 2 above, the uplink and downlink configuration information may be any of 62 formats.

In the embodiment of the present invention, the network device determines, according to the uplink and downlink configuration information, the SAR cumulative value corresponding to the uplink symbol in the second time range in the first time period, by using the following manner: 1) the network device Determining, according to the uplink and downlink configuration information, the number of uplink symbols in the second time range in the first time period; 2) determining, by the network device, a first SAR value corresponding to the first transmit power, and the second The number of uplink symbols in the time range determines a SAR cumulative value corresponding to the uplink symbol in the second time range, where the first transmit power is greater than or equal to the first power value.

Step 303: The network device determines, according to the SAR cumulative value corresponding to the uplink transmission in the first time range and the SAR cumulative value corresponding to the uplink symbol in the second time range, the SAR remaining in the first time period. And adjusting an uplink resource in the second time range based on a SAR margin of the first time period.

In the embodiment of the present invention, the network device is based on the SAR cumulative value corresponding to the uplink transmission in the first time range and the SAR cumulative value corresponding to the uplink symbol in the second time range, and the target SAR threshold value, A SAR margin for the first time period is determined.

The network device monitors the SAR margin in real time, and determines that the SAR margin of the first time period is less than or equal to a first threshold (eg, 0), and the flexible symbol is in the second time range (ie, [t, t1]) No uplink transmission is required, and the maximum transmit power is backed off to 23 dBm.

Based on this, when the time domain position of the first time period changes with the change of the current time, the first time range and the second time range of the first time period also change, based on the foregoing steps 301-303 And updating the SAR margin of the first time period, and adjusting the uplink resource in the second time range according to the updated SAR margin of the first time period. Taking FIG. 2 as an example, suppose that the current time T0 ≤ t ≤ 2 × T0, the SAR accumulation amount corresponding to the uplink transmission in the first T0 period is SAR (s1), and the uplink of the first subframe 1 in the first T0 period The SAR cumulant corresponding to the transmission is SAR (s2), and the SAR cumulant corresponding to the uplink symbol of the subframe n+1 following the last subframe n of the first T0 period is SAR (s3), and the updated The SAR margin for a time period is: SAR(s1)-SAR(s2)+SAR(s3), where SAR(s1) and SAR(s2) can be calculated by the corresponding relationship between transmit power and SAR value, SAR ( S3) can be calculated by using the uplink and downlink configuration information and the first SAR value corresponding to the first transmit power (such as SAR_23). If the subframe n+1 includes n uplink symbols, then SAR(s3)=n×SAR_23. When the SAR margin of the second T0 period (that is, the updated first T0 period) is less than or equal to the first threshold, the network device will be flexible in the second time range (ie, subframe n+1) The symbols do not need to be uplinked, and the maximum transmit power is back to 23dBm.
