Description

Method and device for reporting PHR

Technical field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for reporting a PHR. Background technique

In the Long Term Evolution (LTE) system, two frame structures are supported—Frequency Division Duplex (FDD) and Time Division Duplex (TDD). In the TDD frame structure, a 10 ms radio frame is divided into two half frames of 5 ms in length, each half frame consisting of 5 subframes of length lms, including 4 normal subframes and 1 special subframe. A normal subframe consists of two 0.5ms, and a special subframe consists of three special time slots, called Uplink Pilot Time Slot (UpPTS), guard time slot (GP) and downlink. Downlink Pilot Time Slot (DwPTS), where UpPTS is used for uplink signal transmission, GP is protection interval for TDD uplink and downlink conversion, and DwPTS is used for downlink signal transmission.

As a feature of the TDD system, time resources are allocated in the uplink and downlink directions. The TDD frame structure supports 7 different uplink and downlink time ratio allocations (such as configuration 0~6 shown in Table 1). It can be configured according to the characteristics of the traffic. These seven configurations include three 5ms cycles and four 10ms cycles. In the 5ms periodic configuration, the downlink to uplink transition interval is included every 5ms; in the 10ms periodic configuration, the downlink to uplink transition interval is included every 10ms. The specific configuration is shown in Table 1, where "D" indicates a downlink subframe, "U" indicates an uplink subframe, and "S" indicates a special subframe including a transition interval.

Table 1

(Configuration of TDD uplink and downlink time ratio)

Currently, LTE is discussing the problem of flexible subframe configuration for TDD uplink and downlink. The method of this configuration is that the UE can use the different TDD ratios listed above in a shorter period. For example, in the first 40ms, the UE uses the TDD uplink-downlink ratio of 0, and in the next 40ms, the UE can use the TDD uplink-downlink ratio of 1. This way The advantage is that when the uplink service is long, the system can use the TDD uplink and downlink ratio (for example, the ratio 0) including multiple uplink subframes. When the downlink service is long, the system can use the TDD uplink and downlink ratio (for example, ratio 2) including multiple downlink subframes.

In the prior art, between the uplink and downlink ratios of different TDDs, the subframes that can be used for both uplink and downlink are called uplink and downlink flexible subframes, and the flexible subframes are called flexible subframes. For example, the system configuration UE can convert between the TDD uplink and downlink ratio 0 and the TDD uplink and downlink ratio 2, then the flexible subframe can be subframe 3, subframe 4, subframe 8 and subframe 9.

The current research finds that the interference between the UE in the fixed uplink subframe and the interference of the UE in the flexible upper and lower subframes are very large.

Referring to Figure 2, the current power headroom for fixed uplink subframes (Power Headroom Report,

The process of triggering and reporting (pHR) is: PHR trigger in the case of setting (eg, periodic PHR trigger, PHR trigger when the path loss changes to the threshold and uplink resources, secondary cell) , Scell ) PHR trigger, etc.); Next, after the PHR trigger, the PHR is reported to the base station when there is an uplink resource.

It can be seen that the current UE's PHR trigger and PHR report are separate. That is, when the UE has

In the case of PHR trigger, the UE cannot perform PHR report if there is no uplink resource. Therefore, the possible problem is: If the UE has only uplink resources in the fixed uplink subframe after the PHR trigger, the UE can only calculate the PHR based on the fixed uplink subframe and perform the upper 4艮, correspondingly, if the UE is in the PHR trigger The UE can only calculate the PHR based on the flexible uplink subframe and report it. Therefore, if the base station wants to obtain the complete PHR report, it needs to wait for a certain delay, and can not wait for the resource status. Conduct timely and accurate assessments that affect the overall performance of the system.

For example, as shown in FIG. 2, it is assumed that the UE performs PHR report based on a fixed uplink subframe in the first fixed uplink subframe (as indicated by an upward arrow in FIG. 2), and the next subframe is a flexible uplink and downlink subframe ( As shown by the double-headed arrow in FIG. 2, the base station cannot perform resource estimation on the flexible uplink and downlink subframes by using the PHR report obtained based on the fixed uplink subframe, even if the flexible uplink and downlink subframe is configured as an uplink subframe. Instead, it is necessary to wait for a certain delay (for example, after 5 ms), and the resource evaluation can be performed on the PHR report obtained on the first fixed uplink subframe in the second fixed uplink subframe. Obviously, this is not conducive to timely and accurate base station. Master the state of the system, which is not conducive to the improvement of system performance. Summary of the invention

In the embodiment of the present invention, a manner in which a UE uses a virtual PHR to report a network to obtain a fixed uplink subframe of the UE in time (hereinafter referred to as a fixed subframe) is provided in the embodiment of the present invention. The PHR and the PHR method of flexible uplink and downlink subframes (hereinafter referred to as flexible subframes).

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in FIG. 4, in the embodiment of the present invention, the first process of the PHR reporting by the UE to the base station is as follows: Step 400: After the PHR is triggered, the UE determines to obtain an uplink subframe of the uplink resource.

In the embodiment of the present invention, the UE may determine, in accordance with the scheduling instruction of the base station, which uplink subframes are obtained, and the uplink subframe that obtains the uplink resource may be a fixed subframe or a flexible subframe.

The PHR trigger can be triggered by time. For example, the periodic PHR trigger can also be triggered by an event. For example, when the path loss changes to the threshold and there are uplink resources, PHR trigger, Pcell trigger when Scell is activated, and so on.

Step 410: The UE obtains at least four uplink subframes of the second type on the uplink subframe of the first type of uplink resources.

PHR.

In this embodiment, the first type of uplink subframes may be fixed subframes, and the second type of uplink subframes may be flexible subframes, or the first type of uplink subframes may be flexible subframes, and the second type of uplink subframes. It can also be a fixed subframe.

Specifically, when performing step 410, the UE may use but is not limited to the following methods:

The first mode is: the first type of uplink subframe is a fixed subframe, and the second type of uplink subframe is a flexible subframe, and after the PHR is triggered, the UE reports at least the flexible sub-only on the fixed subframe that obtains the uplink resource. The PHR of the frame.

Optionally, the UE may report the PHR of the flexible subframe and the PHR of the fixed subframe only on the fixed subframe in which the uplink resource is obtained, after the PHR is triggered.

The second mode is: the first type of uplink subframe is a flexible subframe, and the second type of uplink subframe is a fixed subframe, and after the PHR is triggered, the UE only reports at least the fixed subframe on the flexible subframe that obtains the uplink resource. The PHR of the frame. Optionally, the UE may report the PHR of the fixed subframe and the PHR of the flexible subframe at the same time only on the flexible subframe that obtains the uplink resource after the PHR is triggered.

The third mode is: after the PHR is triggered, the UE reports the PHR of the flexible subframe and the PHR of the fixed subframe on the fixed subframe in which the uplink resource is obtained. At this time, the first type of uplink subframe is a fixed subframe. The second type of uplink subframe is a flexible subframe; and, after the PHR is triggered, the UE reports the PHR of the fixed subframe and the PHR of the flexible subframe by reporting the flexible subframe of the uplink resource; The uplink subframe of the class is a flexible subframe, and the uplink subframe of the second type is a fixed subframe.

In other words, the third mode can be expressed as follows: The UE reports both the PHR of the fixed subframe and the PHR of the fixed subframe on both the fixed subframe and the flexible subframe in which the uplink resource is obtained.

The fourth mode is: after the PHR is triggered, the UE determines whether the type of the first type of uplink subframe and the next uplink subframe of the uplink resource are the same, and determines that the next uplink subframe is the second type of uplink subframe, Obtaining, in the uplink subframe of the first type of the uplink resource, the PHR of the uplink subframe of the second type, wherein the uplink subframe of the first type is a fixed subframe, and the uplink subframe of the second type is a flexible subframe, or The first type of uplink subframe is a flexible subframe, and the second type of uplink subframe is a fixed subframe.

Further, in the fourth mode, if it is determined that the type of the uplink subframe and the next uplink subframe of the uplink resource are the same, that is, when the next uplink subframe is the uplink subframe of the first type, On the uplink subframe of the first type of the uplink resource, the PHR of the first type of uplink subframe is reported (that is, the PHR is reported in the same manner as the prior art).

It can be seen that, in the fourth manner, whether the uplink subframe in which the uplink resource is obtained is a fixed subframe or a flexible subframe, the PHR is reported according to the type of the next uplink subframe, that is, if the next uplink subframe is used. If the subframe is a flexible subframe, the UE reports the PHR of the flexible subframe. If the next uplink subframe is a fixed subframe, the UE reports the PHR of the fixed subframe. In this manner, regardless of the current subframe of the 4 艮 PHR. What type of sub-frames can report the PHR of the next sub-frame to the base station in time, so that the system overhead can be effectively reduced and the base station can get the PHR in time.

The fifth mode is: after the PHR is triggered, the UE determines that the first type of uplink subframes that obtain the uplink resource is a fixed subframe, and on the first type of uplink subframe that obtains the uplink resource, The PHR of a subframe (ie, a flexible subframe), and the PHR that reports a fixed subframe.

In other words, the fifth mode can be used to indicate that: if the first type of uplink subframes in which the uplink resource is obtained is a fixed subframe, the UE reports the PHR of the fixed subframe and the PHR of the flexible subframe on the uplink subframe that obtains the uplink resource. .

Further, if the first type of uplink subframes in which the uplink resource is obtained is a flexible subframe, the UE only uses the PHR of the flexible subframe on the uplink subframe that obtains the uplink resource (in the same manner as the prior art) On 4艮PHR). This is because the fixed sub-frame is less irritating and the reliability is better.

In the first mode to the fifth mode, the UE reports the PHR of the second type of uplink subframe, and reports the PHR of the second type of uplink subframe, The PHR of the second type of uplink subframe and the PHR of the first type of uplink subframe may be simultaneously reported by the UE, and the UE may calculate the PHR of the second type of uplink subframe by using the following formula 1 or formula 2: c, s2 (j)- P _c +f _c (m)} Equation 1 where ^ΜΑΧ» is the maximum output power allowed by the UE, P _{PUSe s2} C/) is the PUSCH open loop power of the second type of uplink subframe, and _s2 ( ) is the second The path loss compensation factor of the uplink subframe of class, ^ is! ^Measured downlink path loss, f _c (m) is the power control adjustment value of the first type of uplink subframe that obtains the uplink resource or the power control adjustment value of the last type of uplink subframe of the second type, in order to obtain the uplink resource The subframe number of the uplink subframe or the subframe number of the last uplink subframe of the second type, _/ is the transmission mode identifier, c is the carrier identifier, and s2 is the type identifier of the second type uplink subframe, The subframe number of the first type of uplink subframe of the uplink resource.

The value of the PUSCH is different according to the transmission mode. For example, if the PUSCH carries persistent scheduling and non-adaptive retransmission, then 0, if the PUSCH carries dynamic scheduling and adaptive retransmission, then =1, if the PUSCH bears random Access message, then =2

PH 10 log ₁₀ (M _P ,c,s2 (j) + ^ ₂ (j)-PL + A _T¥ (i) + f _c (m) } Equation 2 where ΜΑΧ is the maximum output power allowed by the UE, M _PUSCTI (0 is the resource size allocated for the PUSCH in the subframe, P _s2 /) is the PUSCH open loop power of the second type of uplink subframe, and " _s2 /" is the path loss compensation factor of the second type of uplink subframe, The PL is the downlink path loss measured by the UE, and A^ii) is the power adjustment value for different modulation and coding modes, and the power control adjustment value of the first type uplink subframe of the uplink resource or the latest second type uplink subframe. The power control adjustment value, m is the subframe number of the first type uplink subframe of the uplink resource or the subframe number of the latest uplink subframe of the second type, _/ is the transmission mode identifier, c is the carrier identifier, s2 For the type identifier of the second type of uplink subframe, the subframe number of the first type of uplink subframe of the uplink resource is obtained;

The value of the PUSCH is different according to the transmission mode. For example, if the PUSCH carries persistent scheduling and non-adaptive retransmission, then 0, if the PUSCH carries dynamic scheduling and adaptive retransmission, then =1, if the PUSCH bears random Access message, then = ² .

Further, in the foregoing first to fifth modes, the UE reports the PHR of the second type of uplink subframes and also reports the first type of uplink subframes in the first type of uplink subframes that obtain the uplink resources. When the PHR is used, the UE may calculate the PHR of the first type of uplink subframe by using the following formula 3: PH ') = ^ΟΜΑΧ - { 10 log ₁₀ ( _PUSCH ( )) + ^PUSC^CSI U) + a _c (j) - PL + Δ _ΤΡ ( ) + ( ) } Equation 3 where ΜΑΧ is allowed by the UE Maximum output power, M _PUSCTI (0 is the resource size allocated for PUSCH in subframe i, and _PUSCH , _e , _sl (J') is the PUSCH open loop power of the first type of uplink subframe, " _e , _sl () is The path loss compensation factor of the first type of uplink subframe, PL is the downlink path loss measured by the UE, and is the power adjustment value for different modulation and coding modes, and the power control adjustment value of the first type of uplink subframe for obtaining the uplink resource is Obtaining a subframe number of the first type of uplink subframe of the uplink resource, where j is a transmission mode identifier, c is a carrier identifier, and si is a type identifier of the uplink subframe of the first type;

The value of the PUSCH is different according to the transmission mode. For example, if the PUSCH carries persistent scheduling and non-adaptive retransmission, then = 0. If the PUSCH carries dynamic scheduling and adaptive retransmission, then = 1 if the PUSCH bears random. Access message, then = 2.

In the embodiment of the present invention, after the PHR is triggered, the UE reports at least the PHR of the second type of uplink subframes on the first type of uplink subframes in which the uplink resources are obtained, so that the base station can be based on the second The PHR of the uplink subframe of the class timely and accurately evaluates the resources in the next subframe in time, thereby effectively ensuring the transmission performance of the system.

For example, still referring to FIG. 2, assuming that the first flexible subframe is configured as an uplink subframe and the second flexible subframe is configured as a downlink subframe (as indicated by the double-headed arrow in FIG. 2), the UE is in the first After a fixed uplink subframe (shown by an upward arrow in FIG. 2), the PHR of the flexible subframe is reported by the base station, and the PHR of the flexible subframe reported by the UE is used to perform resource evaluation on the first flexible subframe in time. Therefore, the transmission performance of the first flexible subframe is guaranteed. Then, the UE reports the PHR of the fixed subframe on the first flexible subframe, and the base station can use the PHR of the fixed subframe reported by the UE to timely fix the second fixed uplink. The subframe performs resource estimation to ensure the transmission performance of the second fixed uplink subframe. In this way, the system overhead can be effectively reduced, and the overall transmission performance of the system can be guaranteed.

For example, as shown in FIG. 2, it is assumed that the first flexible subframe and the second flexible subframe are both configured as uplink subframes, and the UE reports the PHR of the flexible subframe on the first fixed uplink subframe. After that, the base station can use the PHR of the flexible subframe of the UE to perform resource evaluation on the first flexible subframe in time, thereby ensuring the transmission performance of the first flexible subframe. Then, the UE is in the first flexible sub-frame. On the frame, the PHR of the fixed subframe is reported. Since the next uplink subframe is also a flexible subframe, the upper 4 艮 effect is the same as that in the prior art. Then, the UE reports on the second flexible subframe. The PHR of the fixed subframe can be used to perform resource estimation on the second fixed uplink subframe in time by using the PHR of the fixed subframe reported by the UE, thereby ensuring the transmission performance of the second fixed uplink subframe. Thus, although some of the effects on the PHR are the same as in the prior art, from the overall reporting effect, It can still effectively reduce the system overhead to a certain extent, and at the same time ensure the overall transmission performance of the system. As shown in FIG. 5, in the embodiment of the present invention, the second process of the PHR reporting by the UE to the base station is as follows: Step 500: After the PHR is triggered, the UE determines to obtain an uplink subframe of the uplink resource.

Step 510: The UE reports only the PHR of the second type uplink subframe on the first type uplink subframe or/and the second type uplink subframe that obtains the uplink resource, so that the base station can according to the PHR of the second type uplink subframe. And the PHR of the first type of uplink subframe and the PHR of the second type of uplink subframe obtain the PHR of the first type of uplink subframe.

The foregoing offset may be reported by the UE to the base station, or may be pre-agreed by the terminal side and the base station. In the embodiment of the present invention, the UE may determine, in accordance with the scheduling instruction of the base station, which uplink subframes are obtained, and the uplink subframe that obtains the uplink resource may be a fixed subframe or a flexible subframe.

In other words, the manner implemented in step 510 can be expressed as follows: The UE can report only the PHR of the fixed subframe on the fixed subframe and/or the flexible subframe, so that the base station can obtain flexibility through a preset or offset calculation reported by the UE. The PHR of the subframe may be: The UE may also report only the PHR of the flexible subframe on the fixed subframe and/or the flexible subframe, so that the base station can obtain the flexible subframe by using a preset or offset reported by the UE.

PHR.

In the foregoing step 510, when the UE obtains the PHR of the uplink subframe of the second type in the uplink subframe of the uplink resource, the UE may use the following formula 1 or formula 2 to calculate the second uplink. PHR of the sub-frame: c, s2 (j) - P _c + f _c (m) } Equation 1 where ^ΜΑΧ» is the maximum output power allowed by the UE, P. _{PUSe s2} C/) is the PUSCH open loop power of the second type of uplink subframe. _S2 ( ) is the path loss compensation factor of the second type of uplink subframe, ^ is! ^Measured downlink path loss, f _c (m) is the power control adjustment value of the first type of uplink subframe that obtains the uplink resource or the power control adjustment value of the last type of uplink subframe of the second type, in order to obtain the uplink resource The subframe number of the uplink subframe or the subframe number of the last uplink subframe of the second type, _/ is the transmission mode identifier, c is the carrier identifier, and s2 is the type identifier of the second type uplink subframe, The subframe number of the first type of uplink subframe of the uplink resource.

The value of the PUSCH is different according to the transmission mode. For example, if the PUSCH carries persistent scheduling and non-adaptive retransmission, then = 0. If the PUSCH carries dynamic scheduling and adaptive retransmission, then = 1 if the PUSCH bears random. Access message, then = ² . PH () = ^ΜΑΧ-{ 10 log ₁₀ (M _P Li (,■)) + PUSCH,c,s2 (j) + ^ ₂ (j)-PL + A _T¥ (i) + f _c (m) } Equation 2 where ΜΑΧ is the maximum output power allowed by the UE, M _PUSCTI (0 is the resource size allocated for the PUSCH in the subframe, P. _puseH _s2 /) is the PUSCH open loop power of the second type of uplink subframe, " _.s2 /) is the path loss compensation factor of the second type of uplink subframe, PL is the downlink path loss measured by the UE, A^ii) is the power adjustment value for different modulation and coding modes, and f _c (m) is the uplink The power control adjustment value of the first type of uplink subframe of the resource or the power control adjustment value of the latest uplink subframe of the second type, m is the subframe number of the first type of uplink subframe of the uplink resource or the latest one The subframe number of the second type of uplink subframe, _/ is the transmission mode identifier, c is the carrier identifier, and s2 is the type identifier of the second type uplink subframe, and is the subframe number of the first type uplink subframe of the uplink resource;

The value of the PUSCH is different according to the transmission mode. For example, if the PUSCH carries persistent scheduling and non-adaptive retransmission, then 0. If the PUSCH carries dynamic scheduling and adaptive retransmission, then 1, if the PUSCH bears random Access message, then = ² .

In the foregoing step 510, when the UE obtains the PHR of the second type of uplink subframe in the second type of uplink subframe of the uplink resource, the UE may use the following formula 4 to calculate the second type of uplink subframe. PHR:

PH ( = ^CMAX-{ 101ο .(Μ _ρυ ^ _Η (/)) + corpse o- _{PUSC cs2} ( +" _cs2 ( . corpse + (/) ₊ / (/) ] Formula 4 where ^MAX is the user terminal The maximum output power allowed to be set, M _PUSCTI (0 is in subframe i)

The resource size allocated by _PUSCH , _PUSCH , _C , _S 2(J') is the PUSCH open loop power of the second type of uplink subframe, and a _CtS2 (j) is the path loss compensation factor of the second type of uplink subframe, PL is The downlink path loss measured by the user terminal, A^ii) is the power adjustment value for different modulation and coding modes, (/) is the power control adjustment value of the second type uplink subframe that obtains the uplink resource, and is the second to obtain the uplink resource. The subframe number of the uplink subframe of the class, _ / is the transmission mode identifier, c is the carrier identifier, and si is the type identifier of the uplink subframe of the first type;

In this way, the base station can obtain the PHR of the first type of uplink subframe according to the PHR of the second type of uplink subframe reported by the UE, and the offset or the pre-agreed offset of the UE, so that the complete PHR can be obtained in time, and then the pair can be obtained. The resource usage of the uplink subframe is accurately evaluated.

As shown in FIG. 6 , in the embodiment of the present invention, the third process of the PHR reporting by the UE to the base station is as follows: Step 600: After the PHR is triggered, the UE determines to obtain an uplink subframe of the uplink resource. In this embodiment, the first type of uplink subframes may be fixed subframes, and the second type of uplink subframes may be flexible subframes, or the first type of uplink subframes may be flexible subframes, and the second type of uplink subframes. It can also be a fixed subframe.

Step 610: The UE reports the PHR of the first type of uplink subframe, and the second type of uplink subframe that is the closest to the first type of uplink subframe and obtains the uplink resource, in the first type of uplink subframe that obtains the uplink resource. The PHR of the second type of uplink subframe is reported.

In the foregoing step 610, the UE may calculate the PHR of the first type of uplink subframe by using the foregoing formula 3, and the UE may obtain the uplink resource of the second type of uplink subframe by using the foregoing formula 3 on the first type of uplink subframe that obtains the uplink resource. The PHR of the second type of uplink subframe may be calculated by using the above formula 4, and details are not described herein again.

In this way, the UE may start with a PHR trigger, report the PHR of the first type of uplink subframes, and report the PHR of the second type of uplink subframes in a reporting period, and then view that the current reporting process has ended. Therefore, the base station can obtain the complete PHR in time, so that the resource usage of the uplink subframe can be accurately evaluated.

Corresponding to the above-mentioned UE reporting PHR process, referring to FIG. 7, in the embodiment of the present invention, the first process for the base station to receive the PHR is as follows:

Step 700: The base station allocates an uplink resource for transmitting uplink data to the UE.

Step 710: The base station receives at least the PHR of the second type of uplink subframes on the first type of uplink subframes that obtain the uplink resources, where the PHR is reported by the UE.

The second type of uplink subframe is a fixed subframe.

Of course, in the fourth mode, when the base station determines that the next uplink subframe of the first type of uplink subframe of the uplink resource is the first type of uplink subframe, the first type of uplink resource is also obtained. On the subframe, the PHR of the first type of uplink subframe is received.

The PHR, where the second type of uplink subframe is a flexible subframe.

The sixth mode is: the base station receives the PHR of the second type of uplink subframe, and according to the PHR of the second type uplink subframe, and the first type, in the first type of uplink subframe that obtains the uplink resource. The PHR of the uplink subframe is offset from the PHR of the second uplink subframe, and the PHR of the first type of uplink subframe is obtained. The first uplink subframe is a fixed subframe, and the second The uplink subframe of the first type is a flexible subframe, or the uplink subframe of the first type is a flexible subframe, and the uplink subframe of the second type is a fixed subframe.

Further, the base station may further receive the PHR of the second type uplink subframe on the second type uplink subframe that obtains the uplink resource, and according to the PHR of the second type uplink subframe and the first type uplink subframe. The PHR of the PHR and the PHR of the second type of uplink subframes obtain the PHR of the first type of uplink subframe.

The base station may obtain the offset according to the notification of the UE, or may pre-agreed the offset amount with the UE.
