second execution mode
Describe in detail according to another execution mode of the present invention below, this execution mode separately sends the power headroom reporting (PHR) corresponding to PCC and SCC.MACPHRCE corresponding to PCC and SCC is identified by different LCID respectively.
Here first the PHR only for PCC is described.For PCC, the length of its MACPHRCE is fixing.
First, subscriber equipment provides the second control unit head, and this second head comprises the second Logic Channel Identifier, and this second mark is used to indicate this report only containing the power headroom that this PCC is corresponding.Second head length is a byte.Second identification length is 6 bits, and the second head also comprises the reservation bit R of 2 bits and the expansion E of 1 bit.

-for reporting the power headroom except Physical Uplink Shared Channel.
Similar with LTE standard, the PHR value of each power headroom accounts for 6 bit lengths in a shared byte, also comprises the reservation bit R of 2 bits in this byte.Two PHR of principal component carrier wave can arrange according to predefined procedure, and this order can be specified by standard or be arranged in advance by subscriber equipment and base station, or is distinguished by the reservation bit R in PHR content.
As shown in Figure 3, the total length of MACPHRCE is 3 bytes for second head and Part II.
Formed complete MACPHRCE, after creating the second head and the second content part, is sent to base station by subscriber equipment.Correspondingly, base station receives the second control unit head and the second report content part, and therefrom extracts power headroom corresponding to this principal component carrier wave.
Next the PHR only for SCC is described.Because the SCC reported is different at every turn, so subscriber equipment needs to identify two problems in MACPHRCE:
-in this MACPHRCE containing the PHR information of how many SCC;
-each PHR information which SCC corresponding.
In a basic execution mode, subscriber equipment increases by an extra F/L byte after MACPHRCE head, indicates the PHR containing how many SCC in this MACPHRCE.Meanwhile, 2 reservation bit R in the byte using each PHR information to take are to the sequence number of the SCC indicating this PHR and correspond to.Be appreciated that, when existence 4 SCC, 2 bits are enough distinguished 4 SCC.
Concrete, subscriber equipment provides the 3rd control unit head, and the 3rd head comprises the 3rd Logic Channel Identifier, and the 3rd mark is used to indicate this report only containing this execution mode of power headroom that auxiliary component carrier wave is corresponding.3rd head length is 1 byte.
Further, subscriber equipment is provided as the F/L byte of the first number tag, is used to indicate the quantity of auxiliary component carrier wave corresponding to this report.
Meanwhile, provide the 3rd report content part, this Part III comprises the identifier of each auxiliary component carrier wave and the power headroom of this auxiliary component carrier wave respectively.The mark of each SCC accounts for 2 bit lengths, and the PHR value of the power headroom of this SCC accounts for 6 bit lengths.
As shown in Figure 4, the total length of MACPHRCE is 2+k byte, and wherein k is the number of SCC to be reported for 3rd head, F/L byte and the 3rd content part.
Formed complete MACPHRCE, after creating the 3rd head, F/L byte and the 3rd content part, is sent to base station by subscriber equipment.Correspondingly, base station receives the 3rd control unit head, the first number tag and the 3rd report content part, and according to the identifier of the first number tag and each auxiliary component carrier wave, extracts the power headroom of each auxiliary component carrier wave from Part III.
In the execution mode that another is optimized, subscriber equipment uses 2 reservation bits in MACPHRCE head, indicates the PHR containing how many SCC in this MACPHRCE.Namely subscriber equipment is provided as 2 reservation bits in the MACPHRCE head of the first number tag, is used to indicate the quantity of auxiliary component carrier wave corresponding to this report.In the execution mode that this is optimized, relative to execution mode basic above, F/L byte can be saved, and reduces expense.This execution mode as shown in Figure 5.
In the execution mode that another is optimized, subscriber equipment uses 1 reservation bit in MACPHRCE head, and the number indicating the PHR of the SCC contained in this MACPHRCE is one or multiple.When only there being a SCC, relative to execution mode basic above, F/L byte can be saved, and reduces expense.When there being multiple SCC, execution mode basic before continuing to use.The form of this execution mode MACPHRCE in both cases as shown in Figure 6.
3rd execution mode
Describe in detail according to another execution mode of the present invention below, this execution mode sends the PHR information of the one or more component carriers in the component carrier of all configurations.Namely, in a MACPHRCE, any component carrier in a PCC and multiple SCC is comprised.In this case, subscriber equipment needs to identify three problems in MACPHRCE:
The PHR for PCC whether is comprised in-this MACPHRCE;
PHR information containing how many SCC in-this MACPHRCE;
-when including the PHR information of SCC in this MACPHRCE, each PHR information which SCC corresponding.
First, subscriber equipment provides the 4th control unit head, and the 4th head comprises the 4th Logic Channel Identifier, and the 4th mark is used to indicate this report and contains power headroom corresponding to one or more component carriers in all component carriers.
In order to solve above-mentioned first problem, subscriber equipment provides a principal component carrier wave instruction, is used to indicate in this report whether contain power headroom corresponding to principal component carrier wave.In one example in which, subscriber equipment uses a reservation bit in the 4th control unit head to indicate whether comprise PCCPHR.When there is PCCPHR, PCCPHR can be set always in the first place of the PHR of all component carriers.
In a basic execution mode, subscriber equipment increases by an extra F/L byte after MACPHRCE head, indicates the PHR containing how many component carriers in this MACPHRCE.This F/L byte can use as the second number tag of the quantity being used to indicate auxiliary component carrier wave corresponding to this report.
Subscriber equipment also provides the 4th report content part, comprises power headroom corresponding to one or more component carrier in this Part IV.
When there is PCCPHR, this Part IV comprises this PCCPHR and comprises:
-for reporting the power headroom except Physical Uplink Shared Channel and Physical Uplink Control Channel;
-for reporting the power headroom except Physical Uplink Shared Channel.
The PHR value of each power headroom accounts for 6 bit lengths in a shared byte, also comprises the reservation bit R of 2 bits in this byte.Equally, two PHR of PCC can arrange according to reservation order, and this order can be specified by standard or be arranged in advance by subscriber equipment and base station, or is distinguished by the reservation bit R in PHR content.
When there is SCCPHR, 2 reservation bit R in the byte using each PHR information to take are to the sequence number of the SCC indicating this PHR and correspond to, and this PHR value accounts for 6 bit lengths in a shared byte.
The instruction of 4th head, principal component carrier wave, F/L byte and Part IV are as shown in Figure 7.
Formed complete MACPHRCE, after creating the 4th head, the instruction of principal component carrier wave, F/L byte and Part IV, is sent to base station by subscriber equipment.Correspondingly, base station receives the 4th control unit head, the instruction of principal component carrier wave, the second number tag and the 4th report content part, and according to the instruction of this principal component carrier wave and this second number tag, from this Part IV, extract power headroom corresponding to each component carrier.
In an execution mode optimized, if report comprises PCCPHR, two PHR due to PCC comprise the reservation bit of 2 bits, 2 of second PHR reservation bits then can be used to be used as the second number tag, indicate the number of SCCPHR, so F/L byte can be removed, and reduces expense.This execution mode as shown in Figure 8.
Connect the execution mode of above optimization, when not comprising PCCPHR in this report, further optimization, subscriber equipment uses (different from bit shared by principal component carrier wave indicate) 1 reservation bit in MACPHRCE head as the second number tag, and the number indicating the PHR of the SCC contained in this MACPHRCE is one or multiple.If only have a SCCPHR in report, this second number tag can indicate a this situation, then F/L byte can be removed, and reduces expense.This execution mode as shown in Figure 9.If the number of the PHR of SCC is multiple, it is necessary for so introducing F/L byte.And when this report comprises PCCPHR, this bit as the second number tag should be left in the basket to avoid conflict.
Although illustrate in detail in accompanying drawing and aforesaid description and describe the present invention, it is illustrative and exemplary for should thinking that this is illustrated and describes, instead of restrictive; The invention is not restricted to above-mentioned execution mode.
The those skilled in the art of those the art can pass through research specification, disclosed content and accompanying drawing and appending claims, understand and implement other changes to the execution mode disclosed.In the claims, word " comprises " element and step of not getting rid of other, and wording " one " does not get rid of plural number.In the practical application of invention, the function of the multiple technical characteristics quoted during a parts possibility enforcement of rights requires.Any Reference numeral in claim should not be construed as the restriction to scope.
