Specific embodiment

In wireless communication system, in order to reduce sending device power consumption, and reduces unnecessary high power and send to other biographies It is interfered caused by defeated, needs to carry out transmission power control transmission.The size of communication range, communicating pair transceiver most It is big to send the bandwidth etc. occupied for power and receiving sensitivity, the modulation coding scheme of data and rate, the frequency band of work, transmission Factor can all influence to send power.It generally requires under conditions of meeting the received signal quality requirement of receiving end, uses as far as possible Lower transmission power.

In the general communication technology, communication node 1 sends reference signal, and communication node 2 is measured according to the reference signal and saved Point 1 arrives the path loss PL (referred to as path loss) of node 2.PL is to be received with the transmission power of the reference signal of node 1 with node 2 Reference signal reception power difference calculate.Assuming that the PL that node 2 arrives the transmission channel of node 1 arrives the letter of node 2 with node 1 The PL in road is identical, then node 2 can use the transmission power of transmission of the above-mentioned PL calculate node 2 as sending node to node 1.By It is folk prescription planar survey as a result, therefore the factor belongs to ring opening moiety in sending power in PL.It is laggard that node 1 receives transmission Row parsing, quality is that node 2 provides the information of power adjustment based on the received, which belongs to close-loop power control.Wherein, function Rate control can be referred to as power control.

In LTE, the link of base station to terminal is downlink, and the link of terminal to base station is uplink.Downlink Power by base station according to it is each scheduling UE channel measurement and dispatching algorithm determine.The power control of uplink is out The mode of ring combination closed loop.In addition, there are also specific amounts relevant to transmission, such as transmission rate, modulation and coding strategy (Modulation and Coding Scheme, MCS) grade, transmission bandwidth etc. also will affect power.

Here is the transmission rating formula of the PUSCH channel of LTE, as example to influence power parameters into Row explanation.

In the case where carrier wave polymerize (Carrier Aggregation) scene, each UE supports several member carriers CC, each CC is also referred to as a serving cell (Serving Cell).Subscript c refers to serving cell in above formula.From above formula it can be seen that, function Power is sent in rate calculation formula to calculate for serving cell.

The power P of uplink PUSCH_PUSCHRing opening moiety by target received power P_{O_PUSCH}, path loss amount PL and path loss Factor-alpha determines that wherein target received power is divided into cell-level and UE grades of parameters, is all determined by base station and is allocated to UE；And closed loop Part is then that base station according to the gap of measurement result and target determines closed-loop power control adjustment amount, to transmit power control commands The mode of (Transmit Power Control Command, TPC Command) notifies UE, i.e. is directed to PUSCH's in DCI δ_PUSCH.UE safeguards the power adjustment f (i) of a local, is updated according to transmission power control commands, is reached using above-mentioned formula The purpose of closed loop power control.Wherein, i is subframe number, Δ_TFIt is the relevant power excursion of MCS, P_CMAXIt is the maximum power of UE Limitation.

The cell-level target received power P of LTE_{O_PUSCH}Be to discriminate between PUSCH (semi-static, dynamic, message 3MSG3) and PUCCH respectively corresponds different Block Error Rates (Block Error Ratio, BLER) demand.UE grades of target received power parameters P0_UE_specific is also to discriminate between above several and is configured, and is to compensate for systematic bias, such as PL evaluated error, absolutely The error of output power setting.

F (i) is updated according to transmission power control commands and is divided into two ways: accumulating and absolute-value sense, wherein absolute value side Formula is the closed power adjustment amount f (i) that the local UE is directly updated with the transmission power control commands that base station is sent, and accumulating is then by base The history value of the closed power adjustment amount for the transmission power control commands and the local the UE that send of standing determines the closed loop function of the local UE jointly Rate adjustment amount f (i).It should be noted that f (i) here represents the closed power adjustment amount of the local UE.PUCCH is transmitted, Ignore lower target meaning, the closed-loop power control adjustment amount of the local UE in power control formula is indicated with g (i), f (i) meaning with PUSCH It is similar, it is the closed power adjustment amount of the local UE for PUCCH.

The closed power adjustment amount f (i) of the local UE, also referred to as power control adjust state (Power Control Adjustment State)。

The synchronization signal block SSB refers to that the first communication node receives the synchronization signal SS/ physical broadcast of Master Information Block MIB Channel PBCH.

In some embodiments, the operation of following one can also be performed in first communication node:

The reference signal of the path loss parameter associated by the transmission of second frequency domain resource is by before sending, not described Second frequency domain resource sends the transmission of second frequency domain resource；

After the reference signal of the path loss parameter associated by the transmission of second frequency domain resource is sent, described in transmission The transmission of second frequency domain resource；

After the reference signal of the path loss parameter associated by the transmission of second frequency domain resource is sent and measures path loss, Send the transmission of second frequency domain resource.

In detail, UE is configured for several frequency domain resources in some embodiments.Frequency domain resource refers to following one: BWP and CC.

As shown in Figure 1, being provided when UE is instructed to be switched to the second frequency domain resource from the first frequency domain resource according to the first frequency domain The power control parameters in source are made to determine the power control parameters of the second frequency domain resource.

Wherein, in certain frequency domain, several frequency domain resources are restricted to a moment only one of frequency Domain resource is activated.Assuming that be configured with several BWP in a CC, and limit in each CC a moment only one BWP is activated.Certain moment t1, BWP1, which are activated, is used as at least uplink.Thereafter certain moment t2, BWP2 are activated as uplink Transmission.The power control parameters of the uplink of BWP1 may be used to determine whether the power control parameters of the uplink of BWP2.

Wherein, being switched to the second frequency domain resource from the first frequency domain resource may include: the transmission of the second frequency domain resource by The triggering of one frequency domain resource or instruction.Wherein, the scheduling letter of the transmission in the transmission of the first frequency domain resource comprising the second frequency domain resource Breath.For example, the scheduling information of the uplink in the first frequency domain resource comprising the second frequency domain resource.For example, being wrapped in the DCI of BWP1 It is used to dispatch the uplink PUSCH on BWP2 containing uplink scheduling information.

Alternatively, being switched to the transmission that the second frequency domain resource may include: the second frequency domain resource from the first frequency domain resource is pair The response of the transmission of first frequency domain resource.Wherein, the sound of the transmission in the transmission of the second frequency domain resource comprising the first frequency domain resource Answer information.For example, the ack/nack response of the PDSCH transmission sent on BWP1, response message, such as HARQ, in BWP2 On PUCCH or PUSCH in carrying.

Alternatively, being switched to the MAC signaling touching that the second frequency domain resource may include: the first frequency domain resource from the first frequency domain resource Hair or instruction are switched to the second frequency domain resource.For example, the MAC signaling triggering uplink on BWP1 is switched to BWP2, or MAC signaling instruction uplink on BWP1 is switched to BWP2.

For example, UE supports 5 CC, wherein preceding 2 CC are configured as power control frequency domain parameter group 1, rear 3 CC are configured as function Control frequency domain parameter group 2.RRC signaling configures the above parameter.Perhaps RRC signaling configures the above parameter and by MAC layer signaling or object The frequency domain resource group that reason layer signaling selects one or more of which to come into force as current time.

After second frequency domain resource is activated, before the second frequency domain resource sends uplink, it is not received by the second frequency domain RS indicated by the path loss measurement parameter of the uplink of resource is not enough to estimate path loss amount on the time, then according to The power control parameters of one frequency domain resource determine the power control parameters of the second frequency domain resource.

According to the power control parameters of corresponding first frequency domain resource of the reference signal resource information of the transmission of the second frequency domain resource Partially or entirely determine the power control parameters of the transmission of the second frequency domain resource.

Alternatively, determining the power control parameters of the transmission of the second frequency domain resource according to the power control parameters of the transmission of the first frequency domain resource It may include: the power control that the transmission of the second frequency domain resource is determined according to the closed-loop power control parameter of the power control parameters of the first frequency domain resource The closed-loop power control parameter of parameter.Closed-loop power control parameter includes at least one of: closed-loop power control number, closed-loop power control number correspond to Closed-loop power control adjustment amount.

Wherein, the open loop power control parameter of the power control parameters of the second frequency domain resource, closed-loop power control parameter, path loss measurement parameter can The function of the second frequency domain resource of corresponding gain of parameter or use from the power control parameters of the first frequency domain resource is selected independently Control the correspondence parameter of parameter.For example, the power control parameters of the second frequency domain resource can only use the power control parameters of the first frequency domain resource In partial parameters for another example only use the so-called second frequency domain money of path loss measurement parameter in the power control parameters of the first frequency domain resource Path loss measurement parameter in the power control parameters in source, and remaining power control parameters uses and is allocated to the second frequency domain resource.

Citing: when the first frequency domain resource BWP1 is switched to the second frequency domain resource BWP2, even if for BWP2 separate configurations road The RS of loss measurement is arrived among PUSCH sending instant, very if scheduled the PUSCH of BWP2 on BWP1 on being switched to BWP2 Corresponding RS may be had little time to send for BWP2 for path loss measurement, that is to say, that path loss estimation cannot be completed, then BWP1 It is reasonable that path loss measurement parameter, which is used for BWP2,.
