Technical field

The present disclosure relates to the field of mobile communications technologies, and in particular, to a power allocation method and a communication device.

Background technique

In a terminal dual connectivity scenario of a Long Term Evolution (LTE) system, a terminal establishes a connection with two cells, wherein power allocation and power control are calculated and scheduled according to a sub-frame as a minimum unit. In the LTE dual connection, the power allocation is performed according to the cell group (CG, Cell Group) where the base station is located, and a certain proportion of guaranteed power is generally set. For example, the transmit power of the primary cell group (MCG) is X% P _cmax , and the transmit power of the secondary cell group (SCG) is Y% P _cmax , where P _cmax represents the maximum transmit power notified by the base station to the terminal (UE). Wherein, P _cmax lower bound _P cmax_L, the upper bound _P cmax_H, i.e. P _cmax interposed between the two _P cmax_L and _P cmax_H, according to the relevant definition of the relevant standards, _P cmax_L and _P cmax_H as the power can be controlled The change has changed. among them,

P _{cmax_L} =MIN{10log ₁₀ ∑MIN[p _EMAX ,c/(Dt _C ,c),

p _PowerClass /( _mpr _c ·a-mprc·Dt _C ,c·Dt _IB,c ·Dt _ProSe ),p _PowerClass /Pmprc],P _PowerClass }

Where Pmprc comes from power control. That is, P _{CMAX_L} can be changed as power control changes. And P _{CMAX_H} =MIN{10log10∑p _EMAX ,c,P _PowerClass }. The relevant parameters in the above formula can refer to the definition of relevant standards. It can be seen that each sub-frame can calculate an upper bound and a lower bound of a corresponding maximum transmit power. For the definition of the parameters in the above formula, refer to related content in 3GPP TS 36.101 V14.3.0 6.2.5 "Configured transmitted power for CA", and details are not described herein again.

In the dual connectivity scenario of LTE, the upper and lower bounds of P _cmax and the ratio of power allocation can be adjusted in units of subframes. As shown in FIG. 1 , in subframe t1, P _cmax needs to be according to the corresponding subframe p. The upper and lower bounds defined on q are configured. In the next sub-frames p+1 and q+1, P _cmax needs to be set according to the upper and lower bounds defined on p+1 and q+1. The p _cmax at two subframe times can be different, so the following relationship may exist:

_{P cmax_L (p, q) ≤P} cmax (p, q) ≤P cmax_H (p, q);

P _cmax (p, q)! =P _cmax (p+1,q+1).

The above formula P _cmax (p, q) represents the maximum transmit power on the subframes p, q, and P _{cmax_L} (p, q) and P _{cmax_H} (p, q) respectively represent the lower bound of the maximum transmit power on the subframes p, q, respectively. Similar to the upper bound, P _cmax (p+1, q+1) represents the maximum transmit power in subframes p+1, q+1, P _{cmax_L} (p+1, q+1) and P _{cmax_H} ( P+1, q+1) respectively represent the lower bound and upper bound of the maximum transmit power on subframes p+1, q+1.

In the above background, when the base station of the MCG needs to transmit a high-priority service transmission, such as a physical random access channel (PRACH) access, the cell that can be allocated to the MCG transmits more power, such as 70% of the terminals. Transmit power, while the remaining 30% power transmission is used for the SCG's cell. In the subframes of p+1 and q+1, if the SCG needs to transmit a high priority service, 70% of the terminal transmission power can be used for the SCG cell, and the user of the MCG uses 30% of the terminal transmission power. It can be seen that in the case where the two cells are not in conflict, the cells of one cell group can give more power to another cell transmitted by the high priority channel. In the case of general service, two cells can use 40% of the terminal transmit power respectively. In the above solution of the related art, since the power adjustment is performed in units of subframes, the terminal can transmit with different powers at p and p+1, and FIG. 2 shows an example in which the terminal transmits with different powers in different subframes.

A variety of different subframe lengths are introduced in the new air interface (NR) system. For example, different carrier spacings result in different subframe lengths, and introduction of mini slots may also result in different subframe lengths. Figure 3 shows a schematic diagram of the use of different subframe lengths for two cells. According to the LTE-related calculation method, the relevant parameters at the time of T1 and T2 are calculated as follows:

T1: P _{ref_1} =fun(P(p,q),P(p,q-1));

T2: P _{ref_2} =fun(P(p,q),P(p,q+1));

_{_{P ref_1_cmax_L <= P cmax (t1}} ) <= P ref_1_cmax_H;

_{_{P ref_2_cmax_L <= P cmax (t2}} ) <= P ref_2_cmax_H.

Where P(p,q), P(p,q-1), P(p,q+1) represent the reference power of the subframe corresponding to the subframe time, and P _{ref_1} and P _{ref_2} represent the sub-times of T1 and T2, respectively. The reference power of the frame, P _{ref_1_cmax_L} and P _{ref_1_cmax_H} respectively represent the lower bound and upper bound of the reference power P _cmax (t1) of the subframe at time T1, and P _{ref_2_cmax_L} and P _{ref_2_cmax_H} respectively represent the reference power P _cmax (t2) of the subframe at time T2. The lower and upper bounds, fun(x, y) represent the functions associated with x and y. It can be seen that at times T1 and T2, according to the above method, P _cmax (t1) and P _cmax (t2) may be inconsistent. At this time, if the power allocation ratio between the two cell groups does not change, the transmission powers on the two periods before and after the subframe p may be different. When the transmit power in the same subframe changes, it is easy to cause a problem in the channel estimation, and further causes the demodulation failure of the subframe.

In another scenario, as shown in FIG. 4, if the MCG is set to transmit normal traffic on the subframe p, about 40% of the power is occupied by the terminal. In the case of q+2 under SCG, it is necessary to transmit a channel with a high priority, and the power of the occupied terminal is about 70%. The LTE minimum power adjustment is based on the unit of the subframe, and the power adjustment can be performed in the subframe q+2. At this time, if the high-priority subframe is still transmitted at 70% power, it will require more power and further reduce the transmission power of the terminal in the MCG cell, which will also cause the transmission with the MCG in the subframe. A power adjustment has occurred within the network, causing the transmission to fail.

In various embodiments of the present disclosure, it should be understood that the size of the serial numbers of the following processes does not imply a sequence of executions, and the order of execution of each process should be determined by its function and internal logic, and should not be The implementation of some embodiments constitutes any limitation.

Some embodiments of the present disclosure provide a power allocation method for a terminal under dual connectivity, and the method may be applied to a scenario in which a terminal establishes a dual connection with a network. In this scenario, the terminal is connected to a second cell group and a cell in the first cell, and the minimum time domain scheduling unit length of the second cell group is greater than the minimum time domain scheduling unit of the first cell group. The method described in some embodiments of the present disclosure may control the transmit power of the terminal in different cells, avoid or reduce the change of the transmit power in the same minimum time domain scheduling unit, and improve the reliability of information transmission.

Referring to FIG. 5, some embodiments of the present disclosure provide a power allocation method for a dual connectivity in a terminal, where the power allocation method is applied to a network side (specifically, a base station) and includes steps 51-52.

Step 51: Determine a maximum transmit power parameter of a reference minimum time domain scheduling unit.

Step 52: The maximum transmit power parameter of the at least one minimum time domain scheduling unit of the first cell is configured to not exceed the maximum transmit power parameter configured by the reference minimum time domain scheduling unit.

In some embodiments of the present disclosure, the minimum time domain scheduling unit is a minimum time domain unit of the network scheduling terminal, for example, in an LTE system, the unit may be a subframe, and may be a subframe or more than a subframe in the NR system. Small unit. Here, the at least one minimum time domain scheduling unit of the first cell overlaps with a minimum time domain scheduling unit of the second cell in the time domain, where the overlap may be partially overlapping or completely overlapping.

As an implementation manner, the reference minimum time domain scheduling unit may be one or more minimum time domain scheduling units of the at least one minimum time domain scheduling unit. Optionally, the reference minimum time domain scheduling unit may be the first minimum time domain scheduling unit in the at least one minimum time domain scheduling unit.

As another implementation manner, the reference minimum time domain scheduling unit may not be real, but a fictitious unit, which is introduced for power control. At this time, in the foregoing step 51, the maximum transmit power parameter of the reference minimum time domain scheduling unit may be determined according to a maximum transmit power parameter of at least one minimum time domain scheduling unit of the first cell.

Specifically, some embodiments of the present disclosure may configure an upper bound of a maximum transmit power of the reference minimum time domain scheduling unit, not less than an upper bound of a preset maximum transmit power of the at least one minimum time domain scheduling unit, and, And configuring a lower bound of a maximum transmit power of the reference minimum time domain scheduling unit, not greater than a lower bound of a preset maximum transmit power of the at least one minimum time domain scheduling unit. Here, the upper and lower bounds of the preset maximum transmit power of the at least one minimum time domain scheduling unit may be calculated according to a calculation method of the related art (calculated in a similar manner as P _{cmax_L} , P _{CMAX_H} described in the background art). After the upper and lower bounds are determined, the value of the preset maximum transmit power can be selected from the upper and lower bounds.

Specifically, some embodiments of the present disclosure may further configure a maximum transmit power configured by the reference minimum time domain scheduling unit according to a preset maximum transmit power of the at least one minimum time domain scheduling unit of the first cell. Specifically, the maximum transmit power of the reference minimum time domain scheduling unit may be configured according to one or more minimum time domain scheduling units in the at least one minimum time domain scheduling unit. For example, configuring a maximum transmit power of a certain minimum time domain scheduling unit of the at least one minimum time domain scheduling unit as a reference to a maximum transmit power of the minimum time domain scheduling unit. For another example, the maximum transmit power of the reference minimum time domain scheduling unit is configured according to a minimum of the maximum transmit powers of the plurality of minimum time domain scheduling units in the at least one minimum time domain scheduling unit. The plurality of minimum time domain scheduling units may be all or a portion of the minimum time domain scheduling units of the at least one minimum time domain scheduling unit.

Here, the maximum transmit power configured by the reference minimum time domain scheduling unit is predetermined according to a preset maximum transmit power of at least one minimum time domain scheduling unit of the first cell.

In some embodiments of the present disclosure, the number of the at least one minimum time domain scheduling unit may be configured by the network side to the terminal, or may be determined by the terminal according to the minimum time domain scheduling unit length of the first cell and the second cell.

Step 53: Determine a power allocation ratio configured by the reference minimum time domain scheduling unit, where the power allocation ratio is a ratio of a transmission power occupied by the terminal on a corresponding minimum time domain scheduling unit of the first cell to a maximum transmission power of the terminal.

Step 54: Configure a power allocation ratio of the minimum time domain scheduling unit of the terminal in the at least one minimum time domain scheduling unit, which does not exceed a power allocation ratio of the reference minimum time domain scheduling unit.

Step 62: Configure a maximum transmit power of the terminal in the at least one minimum time domain scheduling unit according to the received maximum transmit power parameter.

Here, the at least one minimum time domain scheduling unit of the first cell overlaps with a minimum time domain scheduling unit of the second cell in the time domain. The reference minimum time domain scheduling unit may be one of the at least one minimum time domain scheduling unit; or the reference minimum time domain scheduling unit is in the at least one minimum time domain scheduling unit The first minimum time domain scheduling unit.

In some embodiments of the present disclosure, the maximum transmit power parameter of the reference minimum time domain scheduling unit is determined according to a maximum transmit power parameter of at least one minimum time domain scheduling unit of the first cell. For example, an upper bound of the maximum transmit power of the reference minimum time domain scheduling unit is not less than an upper bound of a preset maximum transmit power of the at least one minimum time domain scheduling unit, and the reference minimum time domain scheduling unit a lower bound of the maximum transmit power, not greater than a lower bound of a preset maximum transmit power of the at least one minimum time domain scheduling unit; and/or a maximum transmit power of the reference minimum time domain scheduling unit is according to the first cell The preset maximum transmit power of at least one minimum time domain scheduling unit is configured.

In the foregoing step 62, when the maximum transmit power parameter is in the range of the maximum transmit power, the maximum transmit power of the terminal in the at least one minimum time domain scheduling unit may be configured, and the range of the maximum transmit power is not exceeded; When the maximum transmit power parameter is the maximum transmit power, the maximum transmit power corresponding to the minimum time domain scheduling unit may be configured according to the received maximum transmit power.

Still further, some embodiments of the present disclosure may further include steps 63-64.

Step 63: Receive a power allocation ratio of any minimum time domain scheduling unit of the terminal configured by the network in the at least one minimum time domain scheduling unit, where the power allocation ratio of any of the minimum time domain scheduling units is not And exceeding a power allocation ratio of the reference minimum time domain scheduling unit, where the power allocation ratio is a ratio of a transmission power of the terminal on a corresponding minimum time domain scheduling unit of the first cell to a maximum transmission power of the terminal.

Step 64: Set the transmit power of the terminal in any of the minimum time domain scheduling units according to the received power allocation ratio.

Through the above methods, some embodiments of the present disclosure implement the configuration of the maximum transmit power parameter of the network to the terminal, which can reduce or avoid the occurrence of the transmit power of the terminal in the second cell, which is reduced or avoided. The signal transmission power of the same minimum time domain scheduling unit of the second cell is changed, so that the reliability of the transmission of the second cell can be improved.

To determine power control parameters for multiple subframes or subframe sets, a reference subframe for power control is defined. As shown in FIG. 11, the subframe set corresponding to the second cell group defines the subframe set of the first cell group (SCG) as {q, q+1, q+2, q+3}. The set of subframes may employ uniform power allocation parameters of the set of subframes. Two different reference subframes are defined here.

Mode 1, the reference subframe is the first subframe in the subframe set, that is, the q subframe.

Mode 2: Refer to all subframes in the subframe set as a reference to define a reference subframe.

The starting point of the reference subframe may start from the subframe q, and the specific location of the subframe may be further defined according to a slot or a symbol of the subframe, considering the synchronous transmission or the asynchronous transmission between the two cells. . Here, the maximum transmission power (reference power) of the reference subframe is defined as P_ref. The power allocation strategy and power definition of all SCGs can be referenced by P_ref.

There are two ways to define P_ref.

In the mode A, the maximum transmit power of the subframe q is used as the reference power of the entire subframe set, and the subsequent subframes q+1, q+2, q+3 cannot exceed the range defined by the maximum transmit power of the subframe q. Here, the range of maximum transmit power definition includes the lower bound Pcmax_L and the upper bound Pcmax_H, that is, the Pcmax of the subsequent subframe cannot exceed the dynamic range of the maximum power defined by the subframe q. In addition, the allocated power allocation ratio of subsequent subframes in the SCG cannot exceed the power allocation ratio of the subframe q.

That is, P_ref=P(q), P(q+1)<=P(q), P(q+2)<=P(q), P(q+3)<=P(q)

Here, P(x) represents the range defined by the maximum transmission power of the subframe x.

In mode B, the dynamic range of the maximum transmit power of the reference subframe depends on the maximum dynamic range of all subframes in the reference subframe set, and the lower bound and the upper bound of the maximum dynamic range are respectively the maximum transmit power of all subframes in the subframe set. The lowest lower bound and the highest upper bound. In addition, the allocated power allocation ratio of subsequent subframes in the SCG cannot exceed the power allocation ratio defined by the reference subframe.

Two examples are provided below to illustrate the above scenario.

Example 1

The base station S1 uses a long subframe, and the base station S2 uses a short subframe, and the terminal performs uplink dual transmission. Still taking FIG. 11 as an example, the subframe p of the base station S1 and the subframes q, q+1, q+2, q+3 of the base station S2 overlap in transmission time. The subframes q and q+1, q+2, and q+3 form a subframe set, and the maximum transmit power of the reference subframe of the subframe set is P_ref, and q, q+1, q+2 in the subframe set, The power configuration of q+3 requires the maximum transmit power of the reference subframe.

Specifically, the reference subframe has P_ref=P(p,q). Here, P(x, y) represents the maximum transmit power of the x, y subframe configuration. P_ref _{cmax_L} and P_ref _{cmax_H} are the upper and lower bounds of _{P_ref} , respectively, and P(x, y) _{cmax_L} and P(x, y) _{cmax_H} are the upper and lower bounds of P(x, y), respectively. Where P_refcmax_L=P(p,q)cmax_L, P_refcmax_H=P(p,q)cmax_H. _{P_ref cmax = P (p, q} ) cmax is the maximum transmit power of the actual configuration. In actual configuration, if the maximum allocated power allocation ratio of the base station S2 is X%, 1-X% is the guaranteed power of the cell S1. Conversely, for the S1 maximum allocated power ratio is Y%, 1-Y% is the guaranteed power of the cell S2.

Here you can also include three configurations:

In configuration mode 1, the upper and lower bounds of the maximum transmit power of all subframes in the subframe set cannot exceed the upper and lower bounds of the maximum transmit power of the reference subframe, that is, the maximum transmit power of all subframes in the subframe set. The bounds are not greater than the upper bound of the maximum transmit power of the reference subframe, and the lower bounds of the maximum transmit power of all subframes in the subframe set are not less than the lower bound of the maximum transmit power of the reference subframe, as shown in FIG. 11:

P(p,q+1) _{cmax_L} >=P_ref _{cmax_L} ;

P(p,q+2) _{cmax_L} >=P_ref _{cmax_L} ;

P(p,q+3) _{cmax_L} >=P_ref _{cmax_L} ;

P(p,q+1) _{cmax_H} <=P_ref _{cmax_H} ;

P(p,q+2) _{cmax_H} <=P_ref _{cmax_H} ;

P(p,q+3) _{cmax_H} <=P_ref _{cmax_H} ;

In configuration mode 2, the maximum transmit power setting of all subframes in the subframe set cannot exceed the maximum transmit power Pcmax of the reference subframe.

P (p, q + 1) cmax_L <= P_ref cmax;

P (p, q + 2) cmax_L <= P_ref cmax;

P (p, q + 3) cmax_L <= P_ref cmax;

In configuration mode 3, the base station S2 _uses the power of X% P _cmax as the maximum transmit power, and the actual transmit power of all subframes in the subframe set cannot exceed the power.

Example 2

The base station S1 uses a long subframe, and the base station S2 uses a short subframe, and the terminal performs uplink dual transmission. The corresponding subframe p and the subframes q, q+1, q+2, q+3 overlap in transmission time. The subframes q and q+1, q+2, and q+3 are combined into a subframe, and the maximum transmit power (reference power) of the reference subframe of the subframe set is P_ref, and q, q+1 in the subframe set. The power of q+2, q+3 needs to refer to the reference power P_ref of the above subframe set.

Wherein, the maximum tolerance of P_ref={P(p,q), P(p,q+1), P(p,q+2), P(p,q+3)} of the subframe set;

specific:

P_ref _{cmax_L} = min{P(p,q) _{cmax_L} , P(p,q+1) _{cmax_L} , P(p,q+2) _{cmax_L} ,P(p,q+3) _{cmax_L} };

P_ref _{cmax_H} =max{P(p,q) _{cmax_H} ,P(p,q+1) _{cmax_H} ,P(p,q+2) _{cmax_H} ,P(p,q+3) _{cmax_H} };

P_ref _{cmax_L} and P_ref _{cmax_H} are the upper and lower bounds of the maximum transmit power of the reference subframe, respectively;

_{P_ref cmax = max {P (p} , q) cmax, P (p, q + 1) cmax, P (p, q + 2) cmax, P (p, q + 3) cmax} is the maximum transmit power of the actual configuration . The other defined relationships are the same as in Example 1.
