Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to a power distribution method and communication equipment.
Background
In a terminal dual connectivity scenario of a Long Term Evolution (LTE) system, a terminal establishes a connection with two cells, where power allocation and power control are performed in units of subframes (subframes) that are the minimum unitsCalculation and scheduling are performed. In LTE dual connectivity, power is allocated according to a Cell Group (CG) where a base station is located, and a certain proportion of guaranteed power is generally set. For example, the transmission power of the Master Cell Group (MCG) is X% PcmaxThe transmission power from the cell group (SCG) is Y% PcmaxHere, PcmaxRepresents the maximum transmit power notified to the terminal (UE) by the base station. Wherein, PcmaxLower boundary of (B) is Pcmax_LUpper bound is Pcmax_HI.e. PcmaxBetween the two Pcmax_LAnd Pcmax_HAccording to the relevant definition of the existing standard, Pcmax_LAnd Pcmax_HMay be varied as power control is varied. Wherein,
Pcmax_L＝MIN{10log10∑MIN[pEMAX,c/(DtC,c),
pPowerClass/(mprc·a-mprc·DtC,c·DtIB,c·DtProSe),pPowerClass/Pmprc],PPowerClass}
where Pmprc is from power control. I.e. PCMAX_LMay be varied as the power control is varied. And P isCMAX_H＝MIN{10log10∑pEMAX,c,PPowerClass}. The relevant parameters in the above formula can be referred to the definition of the existing standard. It can be seen that each subframe can calculate an upper bound and a lower bound of the corresponding maximum transmit power. For the definition of the parameters in the above formula, reference may be made to the relevant contents in 6.2.5a "Configured transmitted data for CA" of 3GPP TS 36.101V14.3.0, which is not described herein again.
In dual connectivity scenario of LTE, PcmaxThe upper and lower bounds and the ratio of power allocation of (b) are adjustable in units of sub-frames, as shown in fig. 1, at sub-frame t1, PcmaxIt needs to be configured according to the upper and lower bounds defined on the corresponding sub-frames p, q. And at the next sub-frames P +1 and q +1, PcmaxIt needs to be set according to the upper and lower bounds defined on p +1 and q + 1. Two sub-frame time instantsP of (a)cmaxMay be different, so the following relationship may exist:
Pcmax_L(p,q)≤Pcmax(p,q)≤Pcmax_H(p,q)
Pcmax(p,q)！＝Pcmax(p+1,q+1)
above formula Pcmax(P, q) denotes the maximum transmission power over sub-frames P, q, Pcmax_L(P, q) and Pcmax_H(P, q) represent the lower and upper bounds of the maximum transmit power over sub-frames P, q, respectively, and similarly, Pcmax(P +1, q +1) then represents the maximum transmit power over sub-frame P +1, q +1, Pcmax_L(P +1, q +1) and Pcmax_H(p +1, q +1) represents the lower and upper bounds of the maximum transmit power over sub-frames p +1, q +1, respectively.
In the above-mentioned context, when a base station of the MCG needs to transmit a high priority traffic transmission, such as a Physical Random Access Channel (PRACH) access, more power can be allocated to a cell of the MCG for transmission, such as 70% of the terminal transmission power, and the remaining 30% of the power transmission is adopted for a cell of the SCG. In the subframes of p +1 and q +1, if SCG needs to transmit high priority traffic, the cell may use 70% of the terminal transmit power for SCG, while the user of MCG uses 30% of the terminal transmit power. It can be seen that in the case where two cells are not colliding in time, the cells of one cell group may give more power to the other cell of the high priority channel transmission. In the case of general service, two cells may respectively use 40% of terminal transmission power. In the above scheme of the prior art, since the power adjustment is performed in units of subframes, the terminal may transmit with different powers from p and p +1, and fig. 2 shows an example in which the terminal transmits with different powers in different subframes.
In a new air interface (NR) system, a plurality of different subframe lengths are introduced, for example, different carrier intervals cause different subframe lengths, and the introduction of a mini slot (mini slot) may cause different subframe lengths. Figure 3 gives a schematic representation of the different subframe lengths employed by the two cells. According to the existing calculation mode of LTE, the relevant parameters at the time of T1 and T2 are calculated as follows:
T1：Pref_1＝fun(P(p,q),P(p,q-1))
T2：Pref_2＝fun(P(p,q),P(p,q+1))
Pref_1_cmax_L<＝Pcmax(t1)<＝Pref_1_cmax_H
Pref_2_cmax_L<＝Pcmax(t2)<＝Pref_2_cmax_H
wherein P (P, q), P (P, q-1), P (P, q +1) represents the reference power of the sub-frame corresponding to the sub-frame time, Pref_1And Pref_2Denotes the reference power, P, of the sub-frames at times T1 and T2, respectivelyref_1_cmax_LAnd Pref_1_cmax_HRespectively representing the reference power P of the sub-frame at the time T1cmaxLower and upper bounds of (t1), Pref_2_cmax_LAnd Pref_2_cmax_HRespectively representing the reference power P of the sub-frame at the time T2cmax(t2), fun (x, y) representing functions related to x and y. It can be seen that at times T1 and T2, P may result according to the method described abovecmax(t1) and Pcmax(t2) disagreement. At this time, if the power allocation ratio between the two cell groups is not changed, it may cause the transmission power to be different in two periods before and after the subframe p. When the transmission power in the same subframe changes, it is easy to cause channel estimation problems, and further cause 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, the power of the terminal is about 40%. And at q +2 under SCG, a high priority channel needs to be transmitted, occupying about 70% of the power of the terminal. In the LTE, the power adjustment is possible in subframe q +2, so that the power adjustment is performed in units of subframes. At this time, if the high-priority subframe is still transmitted at 70% of the power, it will require to occupy more power, and further cause the transmission power of the terminal in the MCG cell to decrease, which will also cause the power adjustment in the subframe by the MCG transmission, thereby causing the transmission failure.

The embodiment of the invention provides a power distribution method under terminal double connection, which can be applied to a scene that a terminal establishes double connection with a network, wherein the terminal establishes connection with a second cell group and one cell in a first cell respectively under the scene, and the minimum time domain scheduling unit length of the second cell group is larger than that of the first cell group.
Referring to fig. 5, the power allocation method under dual connectivity of a terminal according to an embodiment of the present invention, when applied to a network side (specifically, a base station), includes:
51, a maximum transmit power parameter of a reference minimum time domain scheduling unit is determined.
And 52, configuring the maximum transmission power parameter of at least one minimum time domain scheduling unit of the terminal in the first cell, wherein the maximum transmission power parameter does not exceed the maximum transmission power parameter configured by the reference minimum time domain scheduling unit.
In the embodiment of the present invention, the minimum time domain scheduling unit is the minimum time domain unit of the network scheduling terminal, for example, in an LTE system, the unit may be a subframe, and in an NR system, the unit may be a subframe or a unit smaller than a subframe. Here, the at least one minimum time domain scheduling unit of the first cell and one minimum time domain scheduling unit of the second cell are overlapped in a time domain, where the overlap may be a partial overlap or a complete overlap.
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. Preferably, the reference minimum time domain scheduling unit may be a 1 st minimum time domain scheduling unit of the at least one minimum time domain scheduling unit
As another implementation, the reference minimum time domain scheduling unit may not be really present, but an imaginary unit, which is introduced for power control. At this time, in step 51, the maximum transmit power parameter of the reference minimum time domain scheduling unit may be determined according to the maximum transmit power parameter of at least one minimum time domain scheduling unit of the first cell.
Specifically, the embodiment of the present invention may configure an upper bound of the maximum transmission power of the reference minimum time domain scheduling unit to be not less than an upper bound of a preset maximum transmission power of the at least one minimum time domain scheduling unit, and configure a lower bound of the maximum transmission power of the reference minimum time domain scheduling unit to be not more than a lower bound of the preset maximum transmission power of the at least one minimum time domain scheduling unit. Here, the upper and lower bounds of the preset maximum transmission power of the at least one minimum time domain scheduling unit may be calculated according to the prior art (e.g. P described in the background of the invention)cmax_L、PCMAX_HCalculated in a similar manner). After the upper and lower bounds are determined, a value of the preset maximum transmit power may be selected from the range of the upper and lower bounds.
Specifically, the embodiment of the present invention may further configure the maximum transmission power configured by the reference minimum time domain scheduling unit according to a preset maximum transmission power of at least one minimum time domain scheduling unit of the first cell. Specifically, the maximum transmission 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, the maximum transmission power of a minimum time domain scheduling unit in the at least one minimum time domain scheduling unit is configured as the maximum transmission power of the reference 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 a plurality of minimum time domain scheduling units of the at least one minimum time domain scheduling unit. The plurality of minimum time domain scheduling units may be all or part of the at least one minimum time domain scheduling unit.
In step 52, when configuring the maximum transmission power parameter of the terminal in the at least one minimum time domain scheduling unit of the first cell, the embodiment of the present invention may configure the range of the maximum transmission power of the terminal in the at least one minimum time domain scheduling unit of the first cell not to exceed the range of the maximum transmission power configured by the reference minimum time domain scheduling unit, or directly configure the value of the maximum transmission power, for example, configure the maximum transmission power of the terminal in the at least one minimum time domain scheduling unit of the first cell not to exceed the maximum transmission power configured by the reference minimum time domain scheduling unit. Here, the maximum transmission power configured by the reference minimum time domain scheduling unit is predetermined according to a preset maximum transmission power of at least one minimum time domain scheduling unit of the first cell.
In the embodiment of the present invention, the number of the at least one minimum time domain scheduling unit may be configured to the terminal by the network side, or may be determined by the terminal according to the minimum time domain scheduling unit lengths of the first cell and the second cell.
After the step 52, the method according to the embodiment of the present invention may further include the following steps:
and 53, determining a power distribution proportion configured by the reference minimum time domain scheduling unit, wherein the power distribution proportion is a proportion of the transmission power of the terminal on the corresponding minimum time domain scheduling unit of the first cell occupying the maximum transmission power of the terminal.
Step 54, configuring the power allocation proportion of the terminal in any minimum time domain scheduling unit of the at least one minimum time domain scheduling unit, wherein the power allocation proportion does not exceed the power allocation proportion of the reference minimum time domain scheduling unit
Through the configuration of the power distribution proportion, the embodiment of the invention can further avoid the situation that the transmitting power of the terminal in the first cell occupies the transmitting power of the terminal in the second cell, thereby avoiding the change of the signal transmitting power of the same minimum time domain scheduling unit of the second cell, and improving the transmission reliability of the second cell.
Corresponding to the above method, an embodiment of the present invention further provides a power allocation method, applied to a terminal side, as shown in fig. 6, where the method includes:
and step 61, receiving the maximum transmission power parameter of the terminal configured by the network in the at least one minimum time domain scheduling unit of the first cell, wherein the maximum transmission power parameter of the terminal in the at least one minimum time domain scheduling unit of the first cell does not exceed the maximum transmission power parameter configured by the reference minimum time domain scheduling unit.
Step 62, configuring the maximum transmission power of the terminal in at least one minimum time domain scheduling unit according to the received maximum transmission power parameter.
Here, the at least one minimum time domain scheduling unit of the first cell overlaps with one 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 a 1 st minimum time domain scheduling unit of the at least one minimum time domain scheduling unit.
In this embodiment of the present invention, the maximum transmit power parameter of the reference minimum time domain scheduling unit is determined according to the maximum transmit power parameter of at least one minimum time domain scheduling unit of the first cell. For example, the upper bound of the maximum transmission power of the reference minimum time domain scheduling unit is not less than the upper bound of the preset maximum transmission power of the at least one minimum time domain scheduling unit, and the lower bound of the maximum transmission power of the reference minimum time domain scheduling unit is not more than the lower bound of the preset maximum transmission power of the at least one minimum time domain scheduling unit; and/or the maximum transmission power of the reference minimum time domain scheduling unit is configured according to the preset maximum transmission power of at least one minimum time domain scheduling unit of the first cell.
In step 62, when the maximum transmit power parameter is within the range of the maximum transmit power, the maximum transmit power of the terminal in at least one minimum time domain scheduling unit may be configured, and the maximum transmit power does not exceed the range of the maximum transmit power; when the maximum transmission power parameter is the maximum transmission power, the maximum transmission power corresponding to the minimum time domain scheduling unit may be configured according to the received maximum transmission power.
Furthermore, the method according to the embodiment of the present invention may further include:
step 63, receiving a power allocation proportion of the terminal configured by the network in any minimum time domain scheduling unit of the at least one minimum time domain scheduling unit, wherein the power allocation proportion of the any minimum time domain scheduling unit does not exceed the power allocation proportion of the reference minimum time domain scheduling unit, and the power allocation proportion is a proportion of the transmitting power of the terminal on the corresponding minimum time domain scheduling unit of the first cell occupying the maximum transmitting power of the terminal.
Step 64, according to the received power distribution ratio, setting the transmission power of the terminal in any minimum time domain scheduling unit.
Through the method, the embodiment of the invention realizes the configuration of the maximum transmitting power parameter of the terminal by the network, can reduce or avoid the occurrence that the transmitting power of the terminal in the first cell is crowded in the transmitting power of the second cell, and further reduces or avoids the change of the signal transmitting power of the same minimum time domain scheduling unit of the second cell, thereby improving the transmission reliability of the second cell.

Finally, to help understanding the above embodiments, the implementation of the above method of the embodiments of the present invention is further illustrated by taking the subframe of the LTE system as the minimum time domain scheduling unit.
To determine power control parameters for multiple subframes or sets of subframes, a reference subframe for power control is defined. Where the set of subframes of the first cell group (SCG) is defined as { q, q +1, q +2, q +3} corresponding to subframe q of the second cell group, as shown in fig. 11. The set of subframes may employ a uniform power allocation parameter for the set of subframes. Two different reference subframe definitions are provided herein.
In mode 1, the reference subframe is the first subframe in the subframe set, i.e. q subframes.
Mode 2, the reference subframe is defined with reference to all subframes in the reference subframe set.
The start 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 (slot) or a symbol (symbol) of the subframe in consideration of synchronous transmission or non-synchronous transmission between two cells. Here, the maximum transmission power (reference power) of the reference subframe is defined as p _ ref. The power allocation strategy and the power definition of all SCGs can be referred to as P _ ref.
The definition of P _ ref can be made in two ways.
Mode a, with the maximum transmit power of subframe q as the reference power for the entire set of subframes, none of the following subframes q +1, q +2, q +3 can exceed the range defined by the maximum transmit power of subframe q. The range defined by the maximum transmission power here comprises a lower bound Pcmax _ L and an upper bound Pcmax _ H, i.e. the dynamic range in which the Pcmax of the subsequent subframe cannot exceed the maximum power defined by subframe q. In addition, the allocated power allocation ratio of the subsequent subframe within 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) denotes a range defined by the maximum transmission power of the subframe x.
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 lowest lower bound and the highest upper bound of the maximum transmit power of all subframes in the subframe set. In addition, the allocated power allocation ratio of the subsequent subframe within the SCG cannot exceed the power allocation ratio defined by the reference subframe.
Two examples are provided next to illustrate the above.
Example 1
The base station S1 adopts a long subframe, the base station S2 adopts a short subframe, and the terminal performs uplink double transmission. Still taking fig. 11 as an example, subframe p of base station S1 and subframe q, q +1, q +2, q +3 of base station S2 overlap in transmission time. The subframe q and q +1, q +2, q +3 form a subframe set, the maximum transmitting power of a reference subframe of the subframe set is P _ ref, and the maximum transmitting power of the reference subframe is required for the power configuration of q, q +1, q +2, q +3 in the subframe set.
Specifically, P _ ref of the reference subframe is P (P, q). Here, P (x, y) denotes a maximum transmission power of the x, y subframe configuration. P _ refcmax_LAnd P _ refcmax_HUpper and lower bounds of P _ ref, respectively, P (x, y)cmax_LAnd P (x, y)cmax_HUpper and lower bounds of P (x, y), respectively. Wherein, P _ refcmax _ L is P (P, q) cmax _ L, and P _ refcmax _ H is P (P, q) cmax _ H. P _ refcmax＝P(p,q)cmaxIs the maximum transmit power actually configured. In actual configuration, if the base station S2 has maximum allocationThe power distribution ratio of (1-X%) is X%, and 1-X% is the guaranteed power of the cell S1. On the contrary, if the maximum allocated power ratio of S1 is Y%, 1-Y% is the guaranteed power of cell S2.
Here, three configurations may be included:
in configuration mode 1, the upper bound and the lower bound of the maximum transmit power of all subframes in the subframe set cannot exceed the upper bound and the lower bound of the maximum transmit power of the reference subframe, that is, the upper bound of the maximum transmit power of all subframes in the subframe set is not greater than the upper bound of the maximum transmit power of the reference subframe, and the lower bound of the maximum transmit power of all subframes in the subframe set is not less than the lower bound of the maximum transmit power of the reference subframe, taking fig. 11 as an example:
P(p,q+1)cmax_L>＝P_refcmax_L；
P(p,q+2)cmax_L>＝P_refcmax_L；
P(p,q+3)cmax_L>＝P_refcmax_L；
P(p,q+1)cmax_H<＝P_refcmax_H；
P(p,q+2)cmax_H<＝P_refcmax_H；
P(p,q+3)cmax_H<＝P_refcmax_H；
in configuration mode 2, the maximum transmit power settings 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_refcmax；
P(p,q+2)cmax_L<＝P_refcmax；
P(p,q+3)cmax_L<＝P_refcmax；
Configuration 3, base station S2 as X% PcmaxAs maximum transmissionPower, the actual transmit power of all subframes in the set of subframes cannot exceed this power.
Example 2
The base station S1 adopts a long subframe, the base station S2 adopts a short subframe, and the terminal performs uplink double transmission. The corresponding sub-frame p and sub-frame q, q +1, q +2, q +3 overlap in transmission time. The subframe q and q +1, q +2, q +3 form subframe combination, the maximum transmission power (reference power) of a reference subframe of a subframe set is P _ ref, and the powers of q, q +1, q +2, q +3 in the subframe set need to refer to the reference power P _ ref of the subframe set.
Wherein P _ ref of the subframe set is the maximum margin of { P (P, q), P (P, q +1), P (P, q +2), P (P, q +3) };
specifically, the method comprises the following steps:
P_refcmax_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_refcmax_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_refcmax_Land P _ refcmax_HAn upper bound and a lower bound, respectively, of a maximum transmit power of a reference subframe;
P_refcmax＝max{P(p,q)cmax,P(p,q+1)cmax,P(p,q+2)cmax,P(p,q+3)cmaxand the maximum transmission power actually configured. The other defined relationships are the same as in example 1.
