Description

Uplink power control method and device based on flexible subframes in time division duplex mode

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to an uplink power control method and device based on flexible subframes in a Time Division Duplex (TDD) mode.

background

LTE-a (LTE-advanced, Evolution of LTE) is an enhancement of LTE (Long Term Evolution ) technology, which has higher bandwidth requirements than LTE and supports peak data rates up to 1G. Both LTE-a and LTE support two Duplex modes, FDD (Frequency Division Duplex) and TDD (Time Division Duplex).

In the TDD duplexing mode of LTE-a, signals to be transmitted and received are in the same frequency band, and uplink and downlink signal frames are distinguished by being transmitted in different time periods on a time axis, and one signal frame may include: downlink subframes, uplink subframes, special subframes, and flexible subframes. The flexible subframe is a subframe type of LTE-A which is newly increased compared with LTE, and the flexible subframe can be dynamically or semi-statically configured to be a downlink subframe or an uplink subframe.

In LTE, since the uplink employs SC-FDMA technology, the uplink signals of different UEs in a cell are orthogonal, so that the near-far effect of CDMA system does not exist, and the power control of LTE is mainly used to compensate the path loss and shadowing of the channel and to suppress the inter-cell interference. In the prior art, in a TDD duplex mode for LTE, power control is already mature when only downlink subframes, uplink subframes, and special subframes are included in a signal frame, but there is no solution for flexible subframe power control in the TDD duplex mode for LTE-a.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

fig. 1 is a flowchart of an embodiment of a method for controlling uplink power based on flexible subframes in TDD mode, as shown in fig. 1, the embodiment includes the following steps:

s101: generating the transmitting power of each uplink subframe according to the transmitting power of the previous uplink subframe of each uplink subframe in a plurality of uplink subframes respectively, wherein the plurality of uplink subframes comprise: at least one fixed uplink subframe and at least one uplink subframe configured by a flexible subframe;

The fixed uplink subframe refers to a subframe used for uplink transmission in the fixed subframe. The fixed subframes, that is, the subframes where the uplink and downlink attributes cannot be dynamically changed within the valid time of each TDD uplink and downlink configuration, for example, the subframes 0, 1, 2, 5, 6, and 7 in fig. 2. The fixed subframes comprise fixed uplink subframes, fixed downlink subframes and special subframes, wherein the fixed uplink subframes refer to subframes used for uplink transmission in the fixed subframes, the fixed downlink subframes refer to subframes used for downlink transmission in the fixed subframes, and the special subframes comprise three parts: DwPTS (Downlink Pilot Time Slot), UpPTS (Uplink Pilot Time Slot), and GP (Guard Period) between the two parts. The flexible subframe refers to a subframe that can be dynamically or semi-statically configured as an uplink subframe or a downlink subframe. Or, the system notifies the existing version, for example, LTE Rel-8/9/10, of the current 7 uplink and downlink subframe configurations of the ue through broadcast signaling, and for the ue in the evolved system, for example, LTE Rel-11/12, the system may notify different uplink and downlink subframe configurations semi-statically or dynamically, may be the existing 7 configurations, or may add a new uplink and downlink subframe configuration, for example, when the existing system and the evolved system are notified according to 7 configurations, for subframes 3, 4, 5, 6, 7, 8, and 9, the existing system and the evolved system may configure different subframe attributes, that is, whether the subframe is configured as an uplink subframe or a downlink subframe, and thus may be regarded as a flexible subframe, when the existing system and the evolved system are configured according to three uplink and downlink subframes, that the subframes are configured as 0, 1, and 2, the subframes 3, 4, 8 and 9 may be considered flexible subframes. Therefore, the flexible subframe configuration in the embodiment of the present invention can be simply implemented by notifying the uplink and downlink subframe ratio of the ue in the evolved system.

This step is illustrated by way of example: fig. 3 is a schematic diagram of a frame structure including at least one fixed uplink subframe and at least one uplink subframe configured by a flexible subframe. The subframes #3 and #4 are uplink subframes configured by flexible subframes; subframe #2 and subframe #7 are fixed uplink subframes. When the subframe #9 of the previous frame is configured as an uplink subframe, as can be seen from fig. 3, the uplink subframe before the subframe #2 is the subframe #9 of the previous frame, the uplink subframe before the subframe #3 is the subframe #2, the uplink subframe before the subframe #4 is the subframe #3, and the uplink subframe before the subframe #7 is the subframe #4, then the method in this step is adopted to calculate the transmission power of each uplink subframe in the frame specifically as follows: generating the generation power of the sub-frame #2 according to the transmission power of the sub-frame #9 of the previous frame; generating the generation power of the subframe #3 according to the transmission power of the subframe # 2; generating the generation power of the subframe #4 according to the transmission power of the subframe # 3; and generating the generation power of the subframe #7 according to the transmission power of the subframe # 4.

in this and subsequent embodiments, the transmit power of each uplink subframe may include: a transmit power of a PUCCH (Physical Uplink Control Channel) in each Uplink subframe, and/or a transmit power of a PUSCH (Physical Uplink Shared Channel) in each Uplink subframe. Specifically, the two preferred modes can be realized by the following two preferred modes, in the formula related to the two preferred modes, each uplink subframe is represented by an uplink subframe i, and the previous uplink subframe of each uplink subframe is represented by an uplink subframe i-1. And the uplink subframe i and/or the uplink subframe i-1 are fixed uplink subframes or uplink subframes configured by flexible subframes.

optionally, the transmit power of each uplink subframe in the PUCCH may be specifically calculated by formula (1).

P_PUCCH(i)＝min{P_CMAX,P_{0_PUCCH}+PL+h(n_CQI,n_HARQ)+Δ_{F_PUCCH}(F)+g(i)}------(1)

in the formula (1), P_PUCCH(i) represents the transmit power of the PUCCH channel on uplink subframe i.

P_CMAX＝min(P_EMAX,P_UMAX) The maximum transmission power of the user equipment UE on a Primary Component Carrier PCC (Primary Component Carrier) is represented, and the smaller of the maximum power transmission capability of the UE and the maximum transmission power issued by the network side is taken. The maximum power transmission capability of the UE is specifically determined by the class of the UE.

P_{0_PUCCH}Representing the PUCCH channel open loop power.

PL (Path Loss) represents a Path Loss.

Δ_{F_PUCCH}(F) the representation is a compensation for different PUCCH formats.

h(n_CQI,n_HARQ) Is compensation for the number of UCI bits of different uplink control information under the same PUCCH format, n_CQIis the number of bits of CQI, n_HARQis the number of bits of HARQ.

g (i) represents the power control dynamic offset, specifically,the ith uplink subframe has a TPC cumulative amount, delta, relative to the (i-1) th uplink subframe_PUCCHIs a closed loop correction coefficient indicated by a TPC power control command in a DL grant (namely a downlink scheduling signaling comprising DCI Format 1/1A/1B/1D/2/2A/2B) or DCI Format 3/3A.

preferably, in the TPC accumulation process, since there is a history value, that is, the transmission power of the previous uplink subframe can be referred to, equation (1) can be simplified to be approximate to:

optionally, the transmission power of each uplink subframe in the PUSCH specifically includes two cases:

The first condition is as follows: when the uplink subframe i only has a PUSCH or is not configured to have simultaneous transmission of the PUCCH and the PUSCH, if there is a control signaling at this time, the control signaling piggyback is sent to the PUSCH along with data to generate the transmission power of each uplink subframe in the PUSCH, which can be specifically calculated by formula (2):

Case two: and when the uplink subframe i is configured to be simultaneously transmitted by the PUCCH and the PUSCH, generating the transmitting power of each uplink subframe in the PUSCH, wherein the transmitting power can be specifically obtained by calculation of a formula (3). The transmission of the PUCCH is preferentially ensured because the priority of the control channel is high, and the PUSCH is not transmitted if the transmission power of the PUCCH is close to the maximum transmission power Pcmax. Therefore, before obtaining the transmission power of the PUSCH, the transmission power of the PUCCH needs to be obtained first, and the transmission power of the PUCCH is calculated by formula (1) regardless of whether synchronous transmission is configured.

The transmission power of the PUCCH is always derived from equation 1.

in equations (2) and (3):

P_PUSCH(i) and represents the transmission power of the PUSCH channel on the uplink subframe i.

P_CMAX,c＝min(P_EMAX,P_UMAX) The maximum transmission power of the UE on a Component Carrier CC (Component Carrier) is represented by the smaller of the maximum power transmission capability of the UE and the maximum transmission power delivered by the network side. Wherein the maximum power transmission capability of the UE is determined by the class of the UE.

P_{0_PUSCH}representing the open loop power of the PUSCH channel;

PL (Path Loss) represents a Path Loss;

α_c(j) represents a path loss compensation factor;

Δ_TF,c(i) the representation is a compensation for a different MCS;

f (i) represents a power control dynamic offset portion. Specifically, f (i) represents that the power control dynamic offset includes two cases of dynamic offset using cumulative TPC or dynamic offset using absolute TPC. Wherein, when using accumulated TPC f_c(i)＝f_c(i-1)+δ_PUSCH,c(i-K_PUSCH) That is, the ith uplink subframe of the accumulated TPC has an accumulated TPC amount relative to the (i-1) th uplink subframe.

Preferably, in the TPC accumulation process, since the transmit power of the previous uplink subframe can be referred to, for the UE power saving consideration, the transmit power calculation of the PUSCH in equation (2) and/or equation (3) can be simplified approximately as follows:

P_PUSCH(i)＝P_PUSCH(i-1)+δ_PUSCH,c(i-K_PUSCH)

S102: and adopting the transmitting power of each uplink subframe to carry out data transmission on each uplink subframe.

In this embodiment, in the case of subframes including at least one fixed uplink subframe and at least one uplink subframe configured by a flexible subframe, the transmit power of each uplink subframe is generated according to the transmit power of the previous uplink subframe of each uplink subframe in a plurality of uplink subframes, respectively, so that power control in a scenario including flexible subframes is achieved. Further, with the method of this embodiment, when the eNB configures a flexible subframe as an uplink subframe, there is 10 signaling configuration information in the flexible subframe^-2If the false detection occurs, the UE can not determine whether the flexible subframe is an uplink subframe, the power control of each uplink subframe is effectively realized, and the reliability of the power control in a scene including the flexible subframe is improved.

Fig. 4 is a flowchart of an embodiment of a method for controlling uplink power based on flexible subframes in TDD mode, as shown in fig. 4, the embodiment includes the following steps:

s201: generating the transmitting power of each uplink subframe according to the transmitting power of a fixed uplink subframe before each uplink subframe in a plurality of uplink subframes respectively, wherein the plurality of uplink subframes comprise: at least one fixed uplink subframe and at least one uplink subframe configured by a flexible subframe;

this step is illustrated by way of example: fig. 5 is a schematic diagram of a frame structure including at least one fixed uplink subframe and at least one uplink subframe configured by a flexible subframe. The subframes #3 and #4 are uplink subframes configured by flexible subframes; subframe #2 and subframe #7 are fixed uplink subframes. As can be seen from fig. 5, if the previous fixed uplink subframe of subframe #2 is the fixed uplink subframe #7, the previous fixed uplink subframe of subframe #3, the previous fixed uplink subframe of subframe #4, and the previous fixed uplink subframe of subframe #7 in the previous frame are all subframe #2, then calculating the transmit power of each uplink subframe in the frame by using the method in this step specifically includes: generating generation power of a subframe #2 according to the transmission power of the subframe #7 of the previous frame; and generating generation power of the sub-frame #3, the sub-frame #4 and the sub-frame #7 according to the transmission power of the sub-frame # 2.

In this embodiment, the transmit power of each uplink subframe may include: a transmit power of a PUCCH (Physical Uplink Control Channel) in each Uplink subframe, and/or a transmit power of a PUSCH (Physical Uplink Shared Channel) in each Uplink subframe. Specifically, the two preferred modes can be realized by the following two preferred modes, in the formula related to the two preferred modes, each uplink subframe is represented by an uplink subframe i, and the previous fixed uplink subframe of each uplink subframe is represented by a.

preferably, the transmit power of each uplink subframe in the PUCCH is specifically calculated by formula (4).

P_PUCCH(i)＝min{P_CMAX,P_{0_PUCCH}+PL+h(n_CQI,n_HARQ)+Δ_{F_PUCCH}(F)+g(i)}------(4)

Wherein g (i) represents the power control dynamic offset, specifically,a represents that the first a subframes of the subframe i are the first fixed uplink of the subframe iand (5) sub-frame. And g (i) is that the ith uplink subframe has a TPC accumulated quantity relative to the ith-a uplink subframe. The meaning of the other parameters except g (i) in formula (4) is the same as that of formula (1) in example 1, and for the specific explanation, reference is made to example 1, and the details are not repeated here.

preferably, the transmission power of each uplink subframe in the PUSCH specifically includes two cases:

the first condition is as follows: when the uplink subframe i only has a PUSCH or is not configured as a PUCCH and a PUSCH for simultaneous transmission, if there is a control signaling at this time, the control signaling piggyback is sent to the PUSCH along with data to generate the transmission power of each uplink subframe in the PUSCH, which can be specifically calculated by formula (5):

case two: and when the uplink subframe i is configured to be simultaneously transmitted by the PUCCH and the PUSCH, generating the transmission power of each uplink subframe in the PUSCH, wherein the transmission power can be specifically obtained by calculating according to the formula (6).

Specifically, f (i) represents that the power control dynamic offset includes two cases of dynamic offset using cumulative TPC or dynamic offset using absolute TPC. Wherein, when using accumulated TPC f_c(i)＝f_c(a)+δ_PUSCH,c(i-K_PUSCH) That is, the ith uplink subframe of the accumulated TPC has a TPC accumulated amount relative to the ith-a uplink subframe, and the meanings of the parameters other than f (i) in the formulas (5) and (6) are the same as those in the formulas (2) and (3) in the embodiment 1, and for specific explanation, refer to the embodiment 1, which is not described herein again.

S202: and adopting the transmitting power of the current uplink subframe to carry out data transmission on the current uplink subframe.

In this embodiment, in the case of subframes including at least one fixed uplink subframe and at least one uplink subframe configured by a flexible subframe, the transmit power of each uplink subframe is generated according to the transmit power of the previous fixed uplink subframe of each uplink subframe in a plurality of uplink subframes, respectively, so as to implement power control in a scenario including flexible subframes. Furthermore, the flexible subframes are uplink subframes or downlink subframes which can be set by the base station eNB, so that the stability of the flexible subframes is poor.

Fig. 6 is a flowchart of an embodiment of a method for controlling uplink power based on flexible subframes in TDD mode, as shown in fig. 6, the embodiment includes the following steps:

S301: when the previous uplink subframe of the current uplink subframe is an uplink subframe configured by a flexible subframe, generating the transmitting power of the current uplink subframe according to a TPC (transmit power control) accumulated resetting rule; when the previous uplink subframe of the current uplink subframe is a fixed uplink subframe, generating the transmitting power of the current uplink subframe according to the transmitting power of the fixed uplink subframe;

this step is illustrated by way of example: fig. 7 is a schematic diagram of a frame structure including at least one fixed uplink subframe and at least one uplink subframe configured by a flexible subframe. The subframes #3 and #4 are uplink subframes configured by flexible subframes; subframe #2 and subframe #7 are fixed uplink subframes. When the subframe #9 of the previous frame is configured as an uplink subframe, as can be seen from fig. 7, the uplink subframe before the subframe #2 is the subframe #9 configured by the flexible subframe, the uplink subframe before the subframe #3 is the fixed uplink subframe #2, the uplink subframe before the subframe #4 is the uplink subframe #3 configured by the flexible subframe, and the uplink subframe before the subframe #7 is the subframe #4 configured by the flexible subframe, then the method in this step is adopted to calculate the transmission power of each uplink subframe in the frame specifically as follows: generating the transmitting power of the subframe #2 according to a TPC accumulation resetting rule; generating the transmitting power of the subframe #3 according to the transmitting power of the fixed uplink subframe # 2; generating the transmission power of the subframe #4 according to a TPC accumulation resetting rule; and generating the transmission power of the subframe #7 according to the TPC accumulation resetting rule.

In this embodiment, the transmit power of each uplink subframe may include: a transmit power of a PUCCH (Physical Uplink Control Channel) in each Uplink subframe, and/or a transmit power of a PUSCH (Physical Uplink Shared Channel) in each Uplink subframe.
