Specific embodiment
The preferred embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Preferred embodiment, however, it is to be appreciated that may be realized in various forms the disclosure without the embodiment party that should be illustrated here
Formula is limited.On the contrary, these embodiments are provided so that this disclosure will be more thorough and complete, and can be by the disclosure
Range is fully disclosed to those skilled in the art.
Fig. 1 shows the schematic diagram of cordless communication network 100 in the prior art.As shown in fig. 1, cordless communication network
100 include a master base station (MeNB) 110, provides the basic network coverage 120, and one or more prothetic group stations (SeNB)
132,134,136 and 138, the relatively small network coverage 142,144,146 and 148 is provided respectively (with backslash mark in figure
Out).The user equipment (UE) 150 collectively covered in range in master base station and prothetic group station will simultaneously with master base station 110
It establishes and communicates to connect with corresponding prothetic group station (such as prothetic group station 134).
Here, will have simultaneously between a user equipment (UE) and a master base station and one or more prothetic groups station and connect
The case where referred to as dual link.In the following description, with UE (such as UE 150) and a master base station (such as master base station 110) and one
Each embodiment of the invention is described in case where there is dual link between prothetic group station (such as prothetic group station 134).So
And it will be understood by those skilled in the art that scheme described below is also fully applicable for a UE and a master base station and multiple
Prothetic group has the case where dual link between station.
In DC PHR MAC CE structure design of the invention, only consider that the type 2PHR for meeting NS_eNB is constantly present
It enables to guarantee that scheduling base station (S_eNB) can be in the least unambiguously to the DC PHR received in DC PHR MAC CE
MAC CE carries out demultiplexing this condition.It and the use of new Logic Channel Identifier (LCID) is DC come the MAC CE identified into
PHR MAC CE.Therefore key point is how the pH value of the Pcell or PScell of two base stations is placed on DC PHR MAC
Can be realized above-mentioned target.
Based on this, three kinds of different embodiments suggested below.
Fig. 2A and 2B shows the schematic diagram of the DC PHR MAC CE structure of first embodiment according to the present invention, respectively
The case where corresponding to scheduling base station being master base station and prothetic group station.For brevity, the payload of MAC CE is illustrated only in figure
Part, and its packet header is not shown, because packet header and contents of the present invention relationship are little.
The thought of the embodiment is, by the Pcell (when non-scheduled base station is master base station) of non-scheduled base station or
The PH information of PScell (when non-scheduled base station is prothetic group station) is placed on the pre-position of MAC CE, after bit map,
Followed by each small active area is according to another pH value of its cell index, is non-tune without considering that the cell belongs to scheduling base station also
Spend base station.
According to RAN1 agreement, the main difference between the CA PHR MACCE of DC PHR MAC CE and R11 extension is
The type 2PH information of NS_eNB always exists in DCPHR MAC CE.Therefore, if S_eNB can be determined first and be extracted
The PH information of the Pcell or PScell of NS_eNB then can easily extract the PH information of other next cells.
Therefore, in the first embodiment, UE is when reporting PH information by MAC CE, in configuration MAC CE first
Bit map byte.Here, it is known that each bit (other than most right R bit) and dual link in bit map byte
The cell index of each cell at master base station and prothetic group station is corresponding, and bit value indicates whether respective cell is small active area.
For example, the bit value in bit map byte indicates that the corresponding cell of the bit is small active area for 1, it is otherwise inactive small
Area.However, the present invention is not limited thereto, concrete meaning representated by bit value, which can according to need, to be set arbitrarily.
In FIG. 2, it is assumed that the cell index of the PScell at C3 instruction prothetic group station.
In addition, the MAC CE in Fig. 2 is divided into " bit map byte sections " (first for the sake of describing for convenience
Point), " non-scheduled base station PH message part " (second part) and " other small active areas PH message part " (Part III), this
The division of three parts is as shown in Figure 2.
When prothetic group station is non-scheduled base station, 0 is set by the bit for being directed toward the PScell at the prothetic group station in bit map,
That is, setting 0 for the bit value at C3, as shown in Figure 2 A.
Conversely, the bit setting of the PScell at the prothetic group station will be directed toward in bit map when prothetic group station is scheduling base station
It is 1, that is, set 1 for the bit value at C3, as shown in Figure 2 B.This indicates " other small active areas PH information of the MAC CE
There are the pH values of the PScell at prothetic group station in part ".
Next, the pre-position in MAC CE configures the PH information of the Pcell or PScell of non-scheduled base station.
In one implementation, which can be next byte (such as figure after and then bit map byte
Shown in 2A and 2B).Alternatively, the predetermined position is also possible to the end byte of MAC CE.It will be understood by those skilled in the art that
The position of the PH information of the Pcell or PScell of non-scheduled base station can be any predetermined position in MAC CE, which can
With coordinated in advance by UE and scheduling base station or by standard it is prespecified.
Finally, UE is suitable according to the cell index sequence indicated in bit map byte at the other positions in MAC CE
Sequence configures the PH information of other small active areas.
For example, UE can configure other small active areas after the PH information of the Pcell or PScell of non-scheduled base station
PH information, as shown in Figure 2A and 2B.
Here, the cell index of the Pcell of master base station defaults to 0, therefore when master base station is scheduling base station, master base station
The PH information of Pcell is placed on before other movable secondary cells (Scell) in " other small active areas PH message part ".
According to this embodiment, if prothetic group station is non-scheduling base station, " non-scheduled base station PH message part " includes
The PH information of the PScell at prothetic group station.In this way, the corresponding position of " other small active areas PH message part " of the MAC CE does not have
There is the PH information of the PScell at prothetic group station, because the information has been placed in " non-scheduled base station PH message part ".
On the other hand, if prothetic group station is scheduling base station (i.e. master base station is non-scheduling base station), " non-scheduled base station PH letter
Breath part " includes the PH information of the Pcell of master base station.At this moment, the pH value of the PScell at prothetic group station will be placed on by PScell rope
The corresponding position that tendering is known.As shown in Figure 2 B, the pH value of the PScell at prothetic group station is placed on and C3 pairs of cell index at this time
At the position answered.
As can be seen that in this implementation, regardless of non-scheduled base station is master base station or prothetic group station, being directed toward prothetic group station
The bit of PScell be always arranged to 0 or 1, this is not related to the practical UL transmission situation on PScell, but with prothetic group station
It whether is scheduling base station correlation.If prothetic group station is scheduling base station, which is arranged to 1, whereas if prothetic group station right and wrong
Scheduling base station, then the bit is arranged to 0.
This design enables to receive base station convenient for the DC PHR MAC CE received is decoded/is demultiplexed.This
It is because receiving the base station of the DC PHR MAC CE necessarily scheduling base station.So if receiving the base of DC PHR MAC CE
Station is prothetic group station, then prothetic group station is scheduling base station, then the bit for being directed toward the PScell at prothetic group station in bit map byte is set
It is set to 1, the information after bit map byte is the PH information of the Pcell of master base station；And if receiving DC PHR MAC CE's
Base station is master base station, then prothetic group station is non-scheduling base station, then being directed toward the bit of the PScell at prothetic group station in bit map byte
It is arranged to 0, the information after bit map byte is the PH information of the PScell at prothetic group station.
According to the first embodiment, the PH information of non-scheduled base station will occupy 2,3 or 4 bytes, comprising: type 2PH value
Byte+possible type 2Pcmax, c+ Class1 pH value byte+possible Class1 Pcmax, c.The Pcmax of type 2 and Class1,
C, which whether there is, to be determined by the V bit in corresponding type 2 or Class1 pH value byte.These are carried out in 3GPP R11
Definition, therefore which is not described herein again.
In the first embodiment, scheduling base station demultiplex/decode to obtain phase to it after receiving MAC CE
The process for the PH information answered is as follows:
Firstly, scheduling base station is decoded the bit map byte in MAC CE.
Next, scheduling base station knows that the pre-position in MAC CE is the PH information of non-scheduling base station.It is more specific next
It says, scheduling base station knows that next byte of such as bit map byte is the type of the Pcell or PScell of non-scheduling base station
2PH value byte, to be decoded to it.When being decoded to type 2PH value byte, scheduling base station can be according to type
V bit in 2PH value byte determines whether there is type 2Pcmax, c.If there is type 2Pcmax, c, then by type 2PH value
Next byte of byte is decoded as type 2Pcmax, c.
Next, scheduling base station to the Class1 pH value byte of the Pcell or PScell of the non-scheduled base station in MAC CE into
Row decoding.When being decoded to Class1 pH value byte, scheduling base station can be determined according to the V bit in Class1 pH value byte
With the presence or absence of Class1 Pcmax, c.If there is Class1 Pcmax, c, then using next byte of Class1 pH value byte as class
Type 1Pcmax, c are decoded.
After being decoded to " bit map byte sections " and " non-scheduled base station PH message part ", scheduling base station is pressed
According to the sequence of the cell index sequence in bit map byte, at the other positions in MAC CE, scheduling base station is successively decoded
With the PH information (and possible Pcmax, c) of other small active areas of non-scheduled base station.
As can be seen that in the first embodiment, reception base station is master base station or prothetic group station is known.Therefore, than
The bit that the PScell at prothetic group station is directed toward in special bitmap byte in fact comes the master base station or prothetic group station that receive the MAC CE
It says it is all otiose, other purposes can be reused in.
Fig. 3 A and 3B show the schematic diagram of the DC PHR MAC CE structure of second embodiment according to the present invention, respectively
The case where corresponding to scheduling base station being master base station and prothetic group station.It is similar with Fig. 2, effective load of MAC CE is again illustrated only in Fig. 3
Lotus part, and its packet header is not shown.
The thought of the embodiment is, regardless of scheduling base station is master base station or prothetic group station, all by the Pcell of master base station
The pre-position of MAC CE is placed on the PH information of the PScell at prothetic group station, after bit map, followed by it is each its
His small active area is according to another pH value of its cell index sequence, without considering that it belongs to master base station or prothetic group station.
For the sake of description, the MAC CE in Fig. 3 similarly can be divided into " bit map byte sections " (
A part), " the PH message part of Pcell and PScell " (second part) and " other small active areas PH message part " (the
Three parts), the division of this three parts is as shown in Figure 3.
It can be seen that, MAC CE in shown in Fig. 3 second embodiment different from first embodiment shown in Fig. 2
Second part not only included master base station Pcell PH information, but also the PH information of the PScell including prothetic group station.
In Fig. 3, the cell index of the PScell at C3 instruction prothetic group station is similarly assumed.
In this second embodiment, bit of the UE when reporting PH information by MAC CE, in configuration MAC CE first
Bitmap byte.For the embodiment, since the PH information of the PScell at prothetic group station always exists in the second part of MAC CE,
Whether the bit that PScell cell index is therefore directed toward in bit map byte is always set to 0, be to adjust but regardless of prothetic group station
Spend base station.This is for guaranteeing that the correct behavior of scheduling base station is very important.
Next, after bit map byte, the Pcell of the pre-position configuration master base station in MAC CE and auxiliary
The PH information (second part) of the PScell of base station.
In one implementation, which can be next byte (such as figure after and then bit map byte
Shown in 3A and 3B).Alternatively, the predetermined position is also possible to the end byte of MAC CE.It will be understood by those skilled in the art that
The position of the PH information of the PScell of the Pcell and prothetic group station of master base station can be any predetermined position in MAC CE, the position
Setting can be coordinated or prespecified by standard in advance by UE and scheduling base station.
Here, as shown in fig. 3, when scheduling base station is master base station, the PH information of the Pcell of master base station is depended on
The UL transmission situation of Pcell may occupy 1,2,3 or 4 bytes, comprising: possible type 2PH value byte+possible type
2Pcmax, c+ Class1 pH value byte+possible Class1 Pcmax, c, and the PH information of the PScell at prothetic group station includes: type
2PH value byte+possible type 2Pcmax, c+ Class1 pH value byte+possible Class1 Pcmax, c, wherein necessarily including class
Type 2PH value byte.
As shown in Figure 3B, when scheduling base station is prothetic group station, the PH information of the Pcell of master base station may occupy 2,3 or 4
Byte, comprising: type 2PH value byte+possible type 2Pcmax, c+ Class1 pH value byte+possible Class1 Pcmax, c,
It wherein necessarily include type 2PH value byte, and the PH information of the PScell at prothetic group station transmits situation packet depending on the UL of PScell
It includes: possible type 2PH value byte+possible type 2Pcmax, c+ Class1 pH value byte+possible Class1 Pcmax, c.
The Pcmax of type 2 and Class1, c whether there is will be by the V bit in corresponding type 2 or Class1 pH value byte
It determines.These are defined in 3GPP R11, therefore which is not described herein again.
Here, with the PH information of the Pcell of master base station preceding, the PH information of the PScell at prothetic group station is implemented rear to second
Mode is described, however the present invention is not limited thereto, and the two can be arranged with random order.
Finally, UE is at the other positions in MAC CE according to the suitable of the cell index sequence indicated in bit map byte
Sequence configures the PH information of other small active areas.
As can be seen that in this second embodiment, the not scheduled base station of bit for being directed toward the PScell at prothetic group station uses,
It can be reused for other purposes.The case where this is with above-mentioned first embodiment is similar, the difference is that in the second embodiment party
The bit that the PScell at prothetic group station is directed toward in formula should always be set to 0, and in the first embodiment, the bit is not according to
It is arranged to 0 or 1 with situation.
In this second embodiment, scheduling base station demultiplex/decode to obtain phase to it after receiving MAC CE
The process for the PH information answered is as follows:
Firstly, scheduling base station is decoded the bit map byte in MAC CE.
Next, scheduling base station is to the pre-position in the MAC CE, master base station Pcell and prothetic group station
The PH information of PScell is decoded.Here, the PH information of the PScell of the Pcell of master base station and prothetic group station are decoded
Process is similar with described in first embodiment, therefore which is not described herein again.
It needs exist for particularly pointing out, if scheduling base station is master base station, the PH information of the Pcell of master base station is by currently leading
The UL transmission situation of base station determines.That is, type 2PH information by PUCCH whether on the Pcell of master base station configuration/biography
It is defeated and determine, but always include the type 2PH information at prothetic group station.
If scheduling base station is prothetic group station, the second part of MAC CE certainly exists the type 2PH of the Pcell of master base station
Information, and the type 2PH information presence or absence at prothetic group station is that current UL transmission situation on PScell by prothetic group station determines.
After being decoded to " bit map byte sections " and " non-scheduled base station PH message part ", scheduling base station is pressed
According to the sequence of the cell index sequence in bit map byte, at the other positions in MAC CE, scheduling base station is successively decoded
With the PH information (and possible Pcmax) of other small active areas of non-scheduled base station.
Therefore, it can be seen that even for the DC PHR MAC CE for being sent to master base station and prothetic group station in same TTI
For (such as activating any one of these three situations to be triggered by path loss change, P-MPR change and SCell), two DC
PHR MAC CE also will be with different contents.This thought has helped ensure that correct prothetic group station or master base station behavior, and
And it does not need to be concerned about that it is scheduling base station or non-scheduled base station.
Fig. 4 A and 4B show the schematic diagram of the DC PHR MAC CE structure of third embodiment according to the present invention, respectively
The case where corresponding to scheduling base station being master base station and prothetic group station.
The thought of the embodiment is: the PH information of all cells is all placed according to the sequence of its cell index, without
Consider that it belongs to scheduling base station or non-scheduled base station.
In Fig. 4, the cell index of the PScell at C3 instruction prothetic group station is similarly assumed.
In the third embodiment, bit of the UE when reporting PH information by MAC CE, in configuration MAC CE first
Bitmap byte.For the embodiment, the bit that the PScell index at prothetic group station is directed toward in bit map byte is always set
It is 1, because the PH information of the PScell at prothetic group station is always placed on the position as indicated by the bit for being directed toward its cell index
Place.
In this embodiment, MAC CE can only be divided into two parts, i.e. " bit map byte sections " (first
Point) and " PH message part " (second part), this two-part division is as shown in Figure 4.
After bit map byte, UE according to the PH information of each small active area that is arranged in order of cell index sequence,
Belong to scheduling base station or non-scheduled base station but regardless of it.
Specifically, the PH information of the Pcell of master base station is always configured in the beginning of PH message part, because of its cell
Index is 0, and the PH information of the PScell at prothetic group station is configured at the position for being directed toward its cell index, master base station and prothetic group station
The PH information of other activity secondary cells (Scell) configured according to sequence of the index of the cell in bit map byte.
Similar with above-mentioned first and second embodiment, the bit for being directed toward the PScell at prothetic group station still can be continued to employ in advance
In other purposes, because master base station and prothetic group station are very clearly for the Scell index information of PScell.Therefore master base station
Or prothetic group station can be determined clearly be directed toward the bit of the PScell at prothetic group station without have it is any obscure, so the bit can be with
For other purposes.
In the third embodiment, scheduling base station demultiplex/decode to obtain phase to it after receiving MAC CE
The process for the PH information answered is as follows:
Firstly, scheduling base station is decoded the bit map byte in MAC CE.
Next, transmitting situation if scheduling base station is master base station according to the UL of the Pcell of the master base station and decoding the master
The PH information of the Pcell of base station, and according to the cell index sequence indicated in bit map byte, decode next main base
The PH information of the movable Scell and PScell of the movable Scell and prothetic group station that stand.
Here, the PH information of the Pcell of master base station depends on current Pcell UL transmission situation and includes: possible type
2PH value byte+possible type 2Pcmax, c+ Class1 pH value byte+possible Pcmax, c, this is because master base station
The type 2PH information of Pcell only exists in corresponding TTI in configuration/transmission on Pcell in PUCCH.And for being directed toward
The PH information of the PScell of SeNB, content should include: type 2PH value byte+possible type 2Pcmax, c+ Class1 PH
It is worth byte+possible Class1 Pcmax, c, transmits what state but regardless of PScell UL.
If scheduling base station is prothetic group station, scheduling base station directly decodes master base station after decoded bits bitmap byte
The PH information of Pcell, and according to the cell index sequence of bit map byte instruction, decode the activity of next master base station
Scell and prothetic group station movable Scell and PScell PH information, wherein the PH information of the PScell at prothetic group station according to
The UL transmission situation of PScell is decoded.
Here, the PH information of the Pcell of master base station includes type 2PH value byte+possible type 2Pcmax, c+ type
1PH value byte+possible Pcmax, c, the Pcell UL but regardless of current master base station transmit what state.And it is auxiliary for being directed toward
The PH information of the PScell of base station, content depend on current PScell UL transmission situation and include: possible type 2PH value
Byte+possible type 2Pcmax, c+ Class1 pH value byte+possible Pcmax, c.That is, the type 2PH of PScell
Information whether there is by PUCCH whether in corresponding TTI configuration/transmission determines on PScell.
The process that the PH information of the PScell of the Pcell of master base station and prothetic group station are decoded in the third embodiment
It is similar with described in the first and second embodiments, therefore which is not described herein again.
As can be seen that above-mentioned three kinds of schemes ensure that master base station and auxiliary correct behavior.For every kind of scheme, two base stations
DC PHR MAC CE content will be different, even if they generate and send in same TTI.
Further, following problems are also discussed in above-mentioned RAN1 Email discussion:
Problem 1: when UE is not configured as always reporting the virtual PH for the small active area for belonging to another CG/eNB, UE is most
It is big to send whether power (Pcmax) be introduced into PHR.
Problem 2: whether actual Pcmax, c should be used to calculate virtual PH.
If not considering both of these problems, above-mentioned first to the DC PHR MAC CE format design in third embodiment
It is sufficient.
But if it is considered that both of these problems, then DC PHR MAC CE format can be further changed to cope with this
Two problems.
To solve the above-mentioned problems 1, need to consider following two subproblem:
Subproblem 1: scheduling base station how is made to know that Pcmax whether there is；
Subproblem 2: if Pcmax exists, how Pcmax to be configured in DC PHR MAC CE.
For subproblem 1, at least following two solution be can be considered:
Scheme 1: implicit aspect.
In this scenario, whether master base station is configured as always reporting the void of non-scheduled base station about UE to prothetic group station notice
The configuration information of quasi- PH；Then, master base station notifies the master base station and prothetic group station to have shared the configuration information to UE.
In this way regardless of scheduling base station is master base station or prothetic group station, UE all need not explicit instruction Pcmax whether there is.It is adjusting
Base station side is spent, can know that automatically Pcmax whether there is.
For scheme 1, need to define the coordination process between MeNB and SeNB.Then MeNB notifies the coordination to complete to UE
Information so that UE can freely in MAC CE include Pcmax and dispatch eNB be always apparent from whether include
Pcmax。
Scheme 2: explicit aspect
In this scenario, whether UE includes Pcmax to guarantee correct scheduling base station behavior by MAC CE explicit instruction,
It does not need between master base station and prothetic group station about the coordination process of the configuration information of virtual PH report and not needing logical to UE yet
Know the coordination.
In scheme 2, UE decides whether to include Pcmax in MAC CE according to relevant configuration.If it is, UE is in MAC
Corresponding instruction information is configured in CE whether to include Pcmax information to scheduling base station instruction MAC CE.In scheduling base station side,
The instruction information can be checked to determine whether including Pcmax when receiving the MAC CE.
More specifically, UE can reuse the bit map byte in MAC CE first, the right bit (R bit) or
The bit of the PScell at direction prothetic group station is reused to configure the instruction information.
First, the right bit (R bit) of bit map byte is not used in R11, therefore it can be redefined and
Indicate whether to include Pcmax.
And as it is above-mentioned be directed to first to third embodiment description it is found that in above-mentioned MACCE format, be directed toward prothetic group station
PScell bit be in fact for the scheduling base station for receiving the MAC CE it is useless, regardless of scheduling base station be master base station also
It is prothetic group station.And the cell index that RAN2 has agreed to PScell is distributed by master base station, and is forwarded to prothetic group station.Namely
It says, regardless of scheduling base station is master base station or prothetic group station, both knows about the index information of PScell, and therefore it can be accurate
Ground determines which bit is directed toward the PScell at prothetic group station.Therefore be directed toward prothetic group station PScell bit can be redefined with
Indicate whether to include Pcmax information.The scheduling base station for receiving MAC CE can be according to the bit for the PScell for being directed toward prothetic group station
Whether be determined clearly includes Pcmax.
Further, for subproblem 2, Pcmax information can be configured in the specific location in MAC CE.
In one implementation, Pcmax information can be configured after the bit map byte in MAC CE.That is,
It can include an extra byte after bit map byte to place Pcmax information.
It in another implementation, can also be after the PH information of the non-scheduled base station in MAC CE, such as non-scheduled
After the Class1 pH value byte or Class1 Pcmax, c of base station, Pcmax information is configured.The reason is that the byte and non-scheduled base
The PHR process stood is related, therefore is later feasible immediately following the PH information of non-scheduled base station by it.
In response to the above problems 2, it may be considered that following three kinds of schemes:
Scheme 1:UE is determined according to the configuration of wireless heterogeneous networks (RRC) signaling using practical or virtual Pcmax, c
To calculate the virtual pH value of non-scheduled base station.
Scheme 2: being defined UE in a standard by 3GPP and use practical Pcmax, and c calculates the pH value of non-scheduled base station, without
It is virtual or actual for managing the pH value.
Scheme 3:UE freely determines using virtual or practical Pcmax, and c calculates the virtual pH value of non-scheduled base station
Specifically, for scheme 2, scheduling base station can determine that UE uses practical Pcmax, c very much, therefore dispatch
Base station, which will not generate, any obscures.
And for scheme 1 and scheme 3, scheduling base station must be known by using virtual and practical Pcmax in the side UE, in c
Which calculate the virtual pH value of non-scheduled base station.Therefore in both schemes, UE needs to indicate to make to scheduling base station
It is virtual Pcmax, c or practical Pcmax, c.For this purpose, UE can in MAC CE configuration instruction information with to scheduling base
Instruction of standing uses virtual Pcmax, c or practical Pcmax, c.
A bit in MAC CE can be used to configure the instruction information in UE.
In one implementation, the F bit of the F/L byte in MAC CE subheader can be used to configure the instruction information in UE.
This is because the length of load does not exceed 128 bytes, therefore the F bit thing in F/L byte for DC PHR MAC CE
Scheduling is not used in reality.Therefore the bit can be redefined to indicate whether to have used practical Pcmax, c to scheduling base station.
Regulation has been carried out in the structure of MAC CE subheader in R11, therefore which is not described herein again.
In another implementation, the R bit of the bit map byte in MAC CE load can be redefined to configure this
Indicate information.
In another is realized, the bit of the PScell at direction prothetic group station in bit map byte can be redefined to match
Set the instruction information.As described above, the bit for being directed toward the PScell at prothetic group station in bit map byte will not be scheduled, base station makes
With, therefore the bit can be used for this instruction.
In this way, even if V bit in pH value byte is 1, scheduling base station is it is also known that be followed by actual Pcmax, c byte.
Rule is different from R11 for this, and in R11, just there are thereafter Pcmax, c byte in when only V=0.
