Description

Method and device for uplink power control based on flexible subframe in time division duplex mode

technical field

The embodiments of the present invention relate to the field of communication technologies, and in particular to a flexible subframe-based uplink power control method and device in time division duplex TDD mode.

Background technique

LTE-A (LTE-Advance, evolution of LTE) is an enhancement of LTE (Long Term Evolution, long-term evolution) technology. LTE-A has higher bandwidth requirements than LTE and supports a peak data rate of up to 1G. Both LTE-A and LTE support two duplex modes of FDD (Frequency Division Duplex, frequency division duplex) and TDD (Time Division Duplex, time division duplex).

In the TDD duplex mode of LTE-A, the sending and receiving signals are in the same frequency band, and the uplink and downlink signal frames are distinguished by sending them in different time periods on the time axis. A signal frame can include: downlink subframes , uplink subframe, special subframe and flexible subframe. Wherein, the flexible subframe is a subframe type added by LTE-A compared with LTE, and the flexible subframe can be dynamically or semi-statically configured as a downlink subframe or an uplink subframe.

In LTE, since the uplink adopts SC-FDMA technology, the uplink signals of different UEs in a cell are orthogonal, so there is no near-far effect of the CDMA system, and the power control of LTE is mainly used to compensate the channel path loss and shadows and are used to suppress inter-cell interference. In the prior art, in the TDD duplex mode for LTE, the power control is mature when the signal frame only contains downlink subframes, uplink subframes, and special subframes, but the TDD duplex mode for LTE-A contains Flexible subframe power control, no solution yet.

detailed description

In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is a flowchart of an embodiment of an uplink power control method based on flexible subframes in time division duplex TDD mode of the present invention. As shown in Fig. 1, this embodiment includes the following steps:

S101: Generate the transmit power of each uplink subframe according to the transmit power of the previous uplink subframe of each uplink subframe in multiple uplink subframes, the multiple uplink subframes include: at least one fixed uplink subframe A subframe and at least one uplink subframe configured by flexible subframes;

Wherein, the fixed uplink subframe refers to a subframe used for uplink transmission in the fixed subframe. Fixed subframes, that is, subframes whose uplink and downlink properties cannot be dynamically changed within the effective time of each TDD uplink and downlink ratio, such as subframes 0, 1, 2, 5, 6 and 7 in Figure 2 . Fixed subframes include fixed uplink subframes, fixed downlink subframes, and special subframes. Fixed uplink subframes refer to subframes used for uplink transmission in fixed subframes, and fixed downlink subframes refer to subframes used for downlink transmission in fixed subframes. The special subframe includes three parts: DwPT S (Downlink Pilot Time Slot, downlink pilot time slot), UpPT S (Uplink Pilot TimeSlot, uplink pilot time slot), and GP (Guard Period, guard interval). 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 through broadcast signaling, such as LTE Rel-8/9/10, the current seven uplink and downlink subframe configurations of the user equipment, for the evolved system, such as the user equipment of LTE Rel-11/12 , the system can semi-statically or dynamically notify different uplink and downlink subframe ratios. It can add uplink and downlink subframe ratios to the existing seven configurations, for example, when both the existing system and the evolved system When notifying according to the seven 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 , so it can be regarded as a flexible subframe. When both the existing system and the evolved system are configured according to the uplink and downlink subframes 0, 1 and 2, subframes 3, 4, 8 and 9 can be regarded as flexible subframes. Therefore, the flexible subframe configuration in the embodiment of the present invention can be realized simply by notifying the user equipment in the evolved system of the uplink and downlink subframe ratio.

This step is illustrated with an 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 flexible subframes. Wherein, subframe #3 and #4 are uplink subframes configured by flexible subframes; subframe #2 and subframe #7 are fixed uplink subframes. When subframe #9 of the previous frame is configured as an uplink subframe, it can be seen from Figure 3 that the previous uplink subframe of subframe #2 is subframe #9 and subframe #3 of the previous frame The previous uplink subframe of subframe #2 is subframe #2, the previous uplink subframe of subframe #4 is subframe #3, and the previous uplink subframe of subframe #7 is subframe #4, then Using the method described in this step, the calculation of the transmission power of each uplink subframe in the frame is specifically: generating the generation power of subframe #2 according to the transmission power of subframe #9 of the previous frame; The transmission power generates the generation power of subframe #3; generates the generation power of subframe #4 according to the transmission power of subframe #3; generates the generation power of subframe #7 according to the transmission power of subframe #4.

In this embodiment and subsequent embodiments, the transmission power of each uplink subframe may include: the transmission power of a PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) in each uplink subframe, and/or, the The transmit power of PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) in each uplink subframe. Specifically, it can be realized through the following two preferred ways. In the formulas involved in the following two preferred ways, 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 said. 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 can 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 transmission power of the PUCCH channel on the uplink subframe i.

P _CMAX = min(P _EMAX , P _UMAX ) represents the maximum transmission power of the user equipment UE on the primary component carrier PCC (Primary Component Carrier), which is the maximum power transmission capability of the UE and the maximum transmission power issued by the network side the smaller one. Wherein, the maximum power transmission capability of the UE is specifically determined by the class of the UE.

P _{0_PUCCH} represents the open-loop power of the PUCCH channel.

PL (Path Loss) means path loss.

Δ _{F_PUCCH} (F) represents compensation for different PUCCH formats (formats).

h(n _CQI , n _HARQ ) is compensation for the number of UCI bits of different uplink control information in the same PUCCH format, n _CQI is the number of CQI bits, and n _HARQ is the number of HARQ bits.

g(i) represents the power control dynamic offset, specifically, The i-th uplink subframe has a TPC accumulation amount relative to the i-1th uplink subframe, and δ _PUCCH is DL grant (that is, downlink scheduling signaling, including DCI Format 1/1A/1B/1D/2/2A/2B ) or the closed-loop correction coefficient indicated by the TPC power control command in DCI Format 3/3A.

Preferably, in the TPC accumulation process, since there is a historical value, that is, the transmission power of the previous uplink subframe can be referred to, so for the consideration of UE power saving, the formula (1) can be approximately simplified as:

${\mathrm{<span\; class="notranslate">\; P</span>}}_{\mathrm{<span\; class="notranslate">\; PUCCH</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; =</span>{\mathrm{<span\; class="notranslate">\; P</span>}}_{\mathrm{<span\; class="notranslate">\; PUCCH</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; +</span>\underset{\mathrm{<span\; class="notranslate">\; m</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 0</span>}}{\overset{\mathrm{<span\; class="notranslate">\; m</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}}{\mathrm{<span\; class="notranslate">\; \&delta;</span>}}_{\mathrm{<span\; class="notranslate">\; PUCCH</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; -</span>{\mathrm{<span\; class="notranslate">\; k</span>}}_{\mathrm{<span\; class="notranslate">\; m</span>}}<span\; class="notranslate">\; )</span>$

Optionally, the transmission power of each uplink subframe in the PUSCH specifically includes two situations:

Case 1: When the uplink subframe i only has PUSCH or is not configured for PUCCH and PUSCH simultaneous transmission, if there is control signaling at this time, the control signaling is piggybacked to PUSCH and sent together with the data, as described in Generating PUSCH The transmit power of each uplink subframe can be calculated by formula (2):

${\mathrm{<span\; class="notranslate">\; P</span>}}_{\mathrm{<span\; class="notranslate">\; PUSCH</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; min</span>}\left\{\begin{array}{c}{\mathrm{<span\; class="notranslate">\; P</span>}}_{\mathrm{<span\; class="notranslate">\; CMAX</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; )</span>\\ \mathrm{<span\; class="notranslate">\; 10</span>}{\mathrm{<span\; class="notranslate">\; log</span>}}_{\mathrm{<span\; class="notranslate">\; 10</span>}}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; m</span>}}_{\mathrm{<span\; class="notranslate">\; PUSCH</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; )</span><span\; class="notranslate">\; +</span>{\mathrm{<span\; class="notranslate">\; P</span>}}_{\mathrm{<span\; class="notranslate">\; o</span>}<span\; class="notranslate">\; \_</span>\mathrm{<span\; class="notranslate">\; PUSCH</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; j</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; +</span>{\mathrm{<span\; class="notranslate">\; \&alpha;</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; j</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; \&Center\; Dot;</span>{\mathrm{<span\; class="notranslate">\; PL</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; +</span>{\mathrm{<span\; class="notranslate">\; \&Delta;</span>}}_{\mathrm{<span\; class="notranslate">\; TF</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; +</span>{\mathrm{<span\; class="notranslate">\; f</span>}}_{\mathrm{<span\; class="notranslate">\; c</span>}}<span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; )</span>\end{array}\right\}<span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; )</span>$

Case 2: When the uplink subframe i is configured as simultaneous transmission of PUCCH and PUSCH, the transmission power of each uplink subframe in the PUSCH is generated, which can be specifically calculated by formula (3). Wherein, since the priority of the control channel is high, the transmission of the PUCCH is given priority. If the transmission power of the PUCCH is close to the maximum transmission power Pcmax, the PUSCH is not transmitted. Therefore, before obtaining the transmission power of the PUSCH, it is necessary to obtain the transmission power of the PUCCH first, and the transmission power of the PUCCH can be calculated by formula (1) regardless of whether simultaneous interpretation is configured.

The transmit power of PUCCH is always given by Equation 1.

In formula (2) and formula (3):

P _PUSCH (i) represents the transmission power of the PUSCH channel on the uplink subframe i.

P _{CMAX, c} = min(P _EMAX , P _UMAX ) indicates the maximum transmit power of the UE on a component carrier CC (Component Carrier), taking the maximum power transmit capability of the UE and the maximum transmit power issued by the network side The smaller of the . Wherein, the maximum power transmission capability of the UE is determined by the class of the UE.

P _{0_PUSCH} represents the open-loop power of the PUSCH channel;

PL (Path Loss) means path loss;

α _c (j) represents the path loss compensation coefficient;

Δ _{TF, c} (i) means compensation for different MCS;

f(i) represents the power control dynamic offset part. Specifically, f(i) indicates that the dynamic offset of the power control includes the dynamic offset of the accumulated TPC or the dynamic offset of the absolute TPC. Wherein, when using cumulative TPC, f _c (i)=f _c (i-1)+δ _{PUSCH, c} (iK _PUSCH ), that is, the i-th uplink subframe of the cumulative TPC has one TPC accumulation.

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

P _PUSCH (i) = P _PUSCH (i-1) + δ _{PUSCH, c} (iK _PUSCH )

S102: Send data on each uplink subframe by using the transmit power of each uplink subframe.

In this embodiment, in the case of a subframe including at least one fixed uplink subframe and at least one uplink subframe configured by flexible subframes, the previous uplink The transmission power of the subframe generates the transmission power of each uplink subframe, and implements power control in scenarios including flexible subframes. Further, through the method described in this embodiment, when the base station eNB configures a certain flexible subframe as an uplink subframe, but there is a probability of false detection of 10 ^-2 due to the configuration signaling, if a false detection occurs, the UE cannot determine the flexible subframe In the case of whether the frame is an uplink subframe or not, the power control for each uplink subframe is also effectively implemented, which increases the reliability of power control in scenarios including flexible subframes.

FIG. 4 is a flow chart of an embodiment of an uplink power control method based on flexible subframes in the time division duplex TDD mode of the present invention. As shown in FIG. 4, this embodiment includes the following steps:

S201: Generate the transmit power of each uplink subframe respectively according to the transmit power of the previous fixed uplink subframe of each uplink subframe in multiple uplink subframes, where the multiple uplink subframes include: at least one fixed An uplink subframe and at least one uplink subframe configured by flexible subframes;

This step is illustrated with an 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 flexible subframes. Wherein, subframe #3 and #4 are uplink subframes configured by flexible subframes; subframe #2 and subframe #7 are fixed uplink subframes. It can be seen from Figure 5 that the previous fixed uplink subframe of subframe #2 is the previous fixed subframe of fixed subframe #7, subframe #3, subframe #4 and subframe #7 in the previous frame. The uplink subframes are all subframe #2, then use the method described in this step to calculate the transmit power of each uplink subframe in the frame as follows: generate subframe #2 according to the transmit power of subframe #7 in the previous frame Generation power of subframe #2; generate generation power of subframe #3, subframe #4 and subframe #7 according to transmission power of subframe #2.

In this embodiment, the transmission power of each uplink subframe may include: the transmission power of a PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) in each uplink subframe, and/or, each uplink subframe The transmit power of the PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) in . Specifically, it can be realized through the following two preferred ways. In the formulas involved in the following two preferred ways, each uplink subframe is represented by 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 can be 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)

Among them, g(i) represents the power control dynamic offset, specifically, a indicates that the previous a subframes of the subframe i are the previous fixed uplink subframe of the subframe i. g(i) is a TPC accumulation amount of the i-th uplink subframe relative to the ia-th uplink subframe. The meanings of other parameters in the formula (4) except g(i) are the same as those in the formula (1) in the embodiment 1. Please refer to the embodiment 1 for the specific explanation, which will not be repeated here.

Preferably, the transmission power of each uplink subframe in the PUSCH specifically includes two situations:

Case 1: When the uplink subframe i only has PUSCH or is not configured for PUCCH and PUSCH simultaneous transmission, if there is control signaling at this time, the control signaling is piggybacked to PUSCH and sent together with the data, as described in Generating PUSCH The transmit power of each uplink subframe can be calculated by formula (5):

S302: Using the transmit power of the current uplink subframe to transmit data on the current uplink subframe; the current uplink subframe is a fixed uplink subframe or an uplink subframe configured by flexible subframes.

In this embodiment, in the case of a subframe including at least one fixed uplink subframe and at least one uplink subframe configured by a flexible subframe, when the previous uplink subframe of the current uplink subframe is configured by a flexible subframe When the uplink subframe of the current uplink subframe is a fixed uplink subframe, the transmission power of the current uplink subframe is generated according to the TPC cumulative reset rule; when the previous uplink subframe of the current uplink subframe is a fixed uplink subframe, according to the fixed uplink subframe The transmission power generates the transmission power of the current uplink subframe, and implements power control in scenarios including flexible subframes. Furthermore, since the flexible subframe is an uplink subframe or a downlink subframe that can be configured by the base station eNB, its stability is poor. Through the method described in this embodiment, the uncontrollable power caused by the flexible subframe is reduced. The power control of each uplink subframe is implemented effectively, which increases the reliability of power control in scenarios including flexible subframes.

FIG. 8 is a flowchart of an embodiment of an uplink power control method based on flexible subframes in time division duplex TDD mode according to the present invention. As shown in FIG. 8, this embodiment includes the following steps:

S401: When the previous uplink subframe of the current uplink subframe is an uplink subframe configured by flexible subframes, obtain an absolute TPC, and generate the transmit power of the current uplink subframe according to the absolute TPC; when the current uplink subframe When the previous uplink subframe of the subframe is a fixed uplink subframe, generate the transmit power of the current uplink subframe according to the transmit power of the fixed uplink subframe;

This step is illustrated by an example: as shown in FIG. 9, FIG. 9 is a schematic diagram of a frame structure including at least one fixed uplink subframe and at least one uplink subframe configured by flexible subframes. Wherein, subframe #3 and #4 are uplink subframes configured by flexible subframes; subframe #2 and subframe #7 are fixed uplink subframes. When subframe #9 of the previous frame is configured as an uplink subframe, it can be seen from FIG. 7 that the previous uplink subframe of subframe #2 is subframe #9, subframe The previous uplink subframe of #3 is fixed uplink subframe #2, and the previous uplink subframe of subframe #4 is uplink subframe #3 and subframe #7 configured by flexible subframes The previous uplink subframe is subframe #4 configured by flexible subframes, then the method described in this step is used to calculate the transmit power of each uplink subframe in this frame. Specifically: according to the absolute TPC, generate subframe # The transmission power of No. 2; according to the transmission power of the fixed uplink subframe #2, the transmission power of the subframe #3 is generated; according to the absolute TPC, the transmission power of the subframe #4 is generated; according to the absolute TPC TPC, generating transmit power of subframe #7.

In this embodiment, when the previous uplink subframe of the current uplink subframe is a fixed uplink subframe, the transmission power of the current uplink subframe for generating PUCCH and PUSCH is the same as that of Embodiment 2, and will not be described here again. For details, refer to the embodiment 2.

When the previous uplink subframe of the current uplink subframe is an uplink subframe configured by flexible subframes, according to the absolute TPC, the transmission power of the current uplink subframe in the PUCCH is generated, which can be calculated by formula (10).

Through the method described in this embodiment, the uncontrollable power caused by the flexible subframe is reduced. The power control of each uplink subframe is implemented effectively, which increases the reliability of power control in scenarios including flexible subframes.

Wherein, subframes #3, #4 and #8 are uplink subframes configured by flexible subframes; subframe #2 and subframe #7 are fixed uplink subframes. It can be seen from Figure 10 that the previous fixed uplink subframe of fixed uplink subframe #7 is subframe #2; the previous uplink subframe #8 configured by flexible subframe is configured by flexible uplink subframe The uplink subframe is subframe #4, then adopt the method described in this step to generate the transmission power of subframe #7 according to the transmission power of subframe #2; generate the subframe subframe according to the transmission power of subframe #4 #8 transmit power.

The transmit power of the current uplink subframe in PUSCH:

P _PUSCH (i)=P _PUSCH (c)+δ _{PUSCH, c} (iK _PUSCH ) where, when i is a fixed uplink subframe, c is the previous fixed uplink subframe of the current subframe i; When the subframe is configured as an uplink subframe, c is an uplink subframe configured as a flexible subframe before the current subframe i.

In this embodiment, in the case of a subframe including at least one fixed uplink subframe and at least one uplink subframe configured by flexible subframes, when the current uplink subframe is a fixed uplink subframe, according to the current uplink subframe The transmit power of the previous fixed uplink subframe of the frame is used to generate the transmit power of the current uplink subframe; when the current uplink subframe is an uplink subframe configured by flexible subframes, according to the previous The transmission power of an uplink subframe configured by a flexible subframe generates the transmission power of the current uplink subframe, and realizes power control in scenarios including flexible subframes. Furthermore, since the flexible subframe is an uplink subframe or a downlink subframe that can be configured by the base station eNB, its stability is poor. Through the method described in this embodiment, the uncontrollable power caused by the flexible subframe is reduced. The power control of each uplink subframe is implemented effectively, which increases the reliability of power control in scenarios including flexible subframes.
