Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution, and the order of execution of the processes should be determined by the functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
In addition, the terms "system" and "network" are often used interchangeably herein.
In the embodiments provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B may be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may also determine B from a and/or other information.
As shown in fig. 1, an uplink transmission processing method in an embodiment of the present invention is applied to a user equipment, and includes:
Step 101, after a first uplink channel successfully transmits first information, determining a target power spectrum density of a second uplink channel according to a first transmission parameter of the first uplink channel and a second transmission parameter of the second uplink channel to which second information is to be transmitted;
and step 102, transmitting the second information on the second uplink channel according to the target power spectrum density.
In this way, the target power spectral density adopted by the second uplink channel for transmitting the second information is determined based on the first transmission parameter of the first uplink channel which has successfully transmitted the first information and the second transmission parameter of the second uplink channel, and because the first transmission parameter is used by the first uplink channel for successfully transmitting the first information, the success rate of transmitting the second information in the second uplink channel by adopting the determined target power spectral density is improved, and the transmission failure risk of the uplink channel is reduced.
Step 102, transmitting the second information on the second uplink channel, further obtains the target transmission power according to the target power spectral density determined in step 101, and completes the transmission of the second information with the target transmission power.
Optionally, the first transmission parameter includes a first repetition number, a first receive demodulation threshold value, and a first power spectral density; the second transmission parameter comprises a second repetition number and a second receiving demodulation threshold value;
As shown in fig. 2, step 101 includes:
Step 201, obtaining a power spectral density compensation value according to the first repetition number, the first receiving demodulation threshold value, the second repetition number and the second receiving demodulation threshold value;
And 202, compensating the first power spectrum density by using the power spectrum density compensation value to obtain the target power spectrum density of the second uplink channel.
Here, the first repetition number and the first power spectral density are used by the first uplink channel to successfully transmit the first information, the first receiving demodulation threshold value is a configured receiving demodulation threshold value of the first uplink transmission channel, the second repetition number is a configured repetition number of the second uplink channel to transmit the information, and the second receiving demodulation threshold value is a configured receiving demodulation threshold value of the second uplink transmission channel.
Thus, according to step 201 and step 202, after a power spectrum density compensation value is obtained from the first repetition number, the first receiving demodulation threshold value, the second repetition number and the second receiving demodulation threshold value, the first power spectrum density is compensated by the power spectrum density compensation value, so as to obtain a target power spectrum density suitable for transmitting the second information by the second uplink channel. The power spectrum density of the uplink channel to be transmitted is compensated by referring to the transmission parameters of the uplink channel which successfully transmits information, so that the transmission power of the uplink transmission is flexibly adjusted, and the success rate of the uplink channel data transmission is increased.
Optionally, in this embodiment, the power spectral density compensation value includes: a first compensation value and a second compensation value;
Step 201 comprises:
Calculating a first compensation value Δp by the formula Δp=α×10log (r_a/r_b); wherein α is a power spectral density bias spreading factor, r_a is the first repetition number, and r_b is the second repetition number;
Calculating a second compensation value Δt by the formula Δt=threshold_b-threshold_a; wherein threshold_a is the first receive demodulation Threshold value, and threshold_b is the second receive demodulation Threshold value.
From this, Δp is used to compensate for the difference in the number of repetitions between r_a and r_b. Where, if α=1, r_a=8, and r_b=2, Δp=1×10log (8/2) =6 dB. That is, it can be understood that since the number of repetitions of the second uplink channel is smaller than that of the first uplink channel, it is necessary to compensate for the loss of the number of repetitions in power.
And Δt is a difference between the reception demodulation thresholds of the first uplink channel and the second uplink channel. Wherein, if threshold_a= -110dBm, threshold_b= -112dBm, Δt= -2dB. That is, it can be appreciated that the second uplink channel needs to be reduced in transmit power spectral density by 2dB because of its lower receive demodulation threshold.
The receiving demodulation threshold value of the uplink channel is issued by a system message such as a system message 2 (SIB 2) or a system message 1 (SIB 1).
It should be noted that, in this embodiment, the second uplink channel is an uplink channel for transmitting the second information, and the first uplink channel is an uplink channel for successfully transmitting the first information before the second information is transmitted, so the first uplink channel may be determined as the uplink channel for transmitting the information last time only by limiting the time; or by further combining the definition of the first information, determining an uplink channel for which the specific information is transmitted last time.
Optionally, the second uplink channel and the first uplink channel are the same channel or different channels.
For example, the first Uplink channel and the second Uplink channel are PUSCH (Physical Uplink SHARED CHANNEL ); or the first uplink channel is PRACH (Physical Random ACCESS CHANNEL), the second uplink channel is PUSCH, and so on.
Generally, NB-IoT (Narrow Band Internet of Things ) is an important branch of the internet of everything, capable of supporting cellular data connections of low power devices over wide area networks. Due to the advantages of low power consumption, wide coverage, low cost, large capacity and the like of NB-IoT, the method is widely applied to various vertical industries. And NPRACH (Narrow Physical Random ACCESS CHANNEL, narrowband physical random access channel) power control and NPUSCH (Narrow Physical Uplink SHARED CHANNEL, narrowband physical uplink shared channel) power control are two independent power control mechanisms, so that the method of the embodiment of the invention is applicable to NB-IoT systems, and optionally, the first uplink channel and the second uplink channel are both narrowband uplink channels.
Optionally, the first information is a first signaling MSG1 based on a non-contention random access procedure, and the second information is a third signaling MSG3 based on a contention random access procedure.
Specifically, the first uplink channel for transmitting MSG1 is NPRACH, and the second uplink channel for transmitting MSG3 is NPUSCH.
For example, for NB-IoT, the number of repetitions was 8 with a power spectral density of-3 dBm/15Hz upon successful transmission of MSG1 via NPRACH. NPUSCH transmitting MSG3 sets the repetition number to 2 in order to meet the power control requirement. And, setting the receiving demodulation threshold of NPRACH of the transmission MSG1 to-120 dBm and the receiving demodulation threshold of the NPUSCH of the transmission MSG3 to-118 dBm, when α=1, the power spectrum density of the NPUSCH transmission MSG3 is-3 dBm/15khz+10×log (8/2) +(-118 dBm- (-120 dBm))=5 dBm/15KHz.
Of course, the method of the embodiment of the invention is also suitable for transmitting the PUSCH or PUCCH (Physical Uplink Control Channel ) carrying the control information after the PUSCH carrying the user data is successfully transmitted. The control information may be UCI (Uplink Control Information ), uplink RRC (Radio Resource Control, radio resource control) information, uplink MR (Measurement Report ), and the like.
Optionally, the first uplink channel is PUSCH, and the second uplink channel is PUSCH or PUCCH.
Optionally, the first information is MSG3 of a contention-based random access procedure, and the second information is fifth signaling MSG5 of the contention-based random access procedure.
Specifically, the first uplink channel for transmitting MSG3 is PUSCH, and the second uplink channel for transmitting MSG5 is PUSCH.
For example, for 5G NR (New Radio), the number of repetitions is 8 and the power spectral density is-3 dBm/15Hz when MSG3 is successfully transmitted over the PUSCH. The PUSCH for transmitting MSG5 is repeated for 2 times to meet the power control requirement. Further, when the receiving demodulation threshold of PUSCH for MSG3 is set to-120 dBm and the receiving demodulation threshold of PUSCH for MSG5 is set to-120 dBm, and α=1, the power spectrum density of PUSCH for MSG5 is-3 dBm/15khz+10×log (8/2) +(-120 dBm- (-120 dBm))=3 dBm/15KHz.
In summary, according to the method of the embodiment of the present invention, the target power spectral density used for transmitting the second information by the second uplink channel is determined based on the first transmission parameter of the first uplink channel that has successfully transmitted the first information and the second transmission parameter of the second uplink channel, and since the first transmission parameter is used for successfully transmitting the first information by the first uplink channel, the success rate of transmitting the second information by using the determined target power spectral density in the second uplink channel is improved, and the transmission failure risk of the uplink channel is reduced.
As shown in fig. 3, an uplink transmission processing apparatus according to an embodiment of the present invention includes:
A processing module 310, configured to determine, after a first uplink channel successfully transmits first information, a target power spectral density of a second uplink channel according to a first transmission parameter of the first uplink channel and a second transmission parameter of the second uplink channel to which second information is to be transmitted;
and a transmission module 320, configured to transmit the second information on the second uplink channel according to the target power spectral density.
In this way, the target power spectral density adopted by the second uplink channel for transmitting the second information is determined based on the first transmission parameter of the first uplink channel which has successfully transmitted the first information and the second transmission parameter of the second uplink channel, and because the first transmission parameter is used by the first uplink channel for successfully transmitting the first information, the success rate of transmitting the second information in the second uplink channel by adopting the determined target power spectral density is improved, and the transmission failure risk of the uplink channel is reduced.
Optionally, the first transmission parameter includes a first repetition number, a first receive demodulation threshold value, and a first power spectral density; the second transmission parameter comprises a second repetition number and a second receiving demodulation threshold value;
The processing module comprises:
The first processing sub-module is used for obtaining a power spectrum density compensation value according to the first repetition times, the first receiving demodulation threshold value, the second repetition times and the second receiving demodulation threshold value;
and the second processing submodule is used for compensating the first power spectrum density by using the power spectrum density compensation value to obtain the target power spectrum density of the second uplink channel.
Here, the first repetition number and the first power spectral density are used by the first uplink channel to successfully transmit the first information, the first receiving demodulation threshold value is a configured receiving demodulation threshold value of the first uplink transmission channel, the second repetition number is a configured repetition number of the second uplink channel to transmit the information, and the second receiving demodulation threshold value is a configured receiving demodulation threshold value of the second uplink transmission channel.
In this way, in the device of the embodiment of the present invention, after the first processing sub-module obtains a power spectrum density compensation value from the first repetition number, the first receiving demodulation threshold value, the second repetition number and the second receiving demodulation threshold value, the second processing sub-module compensates the first power spectrum density with the power spectrum density compensation value, so as to obtain a target power spectrum density suitable for the second uplink channel to transmit the second information. The power spectrum density of the uplink channel to be transmitted is compensated by referring to the transmission parameters of the uplink channel which successfully transmits information, so that the transmission power of the uplink transmission is flexibly adjusted, and the success rate of the uplink channel data transmission is increased.
Optionally, the power spectral density compensation value includes: a first compensation value and a second compensation value;
The first processing submodule includes:
A first calculation unit for calculating a first compensation value Δp by the formula Δp=α×10log (r_a/r_b); wherein α is a power spectral density bias spreading factor, r_a is the first repetition number, and r_b is the second repetition number;
a second calculation unit for calculating a second compensation value Δt by the formula Δt=threshold_b-threshold_a; wherein threshold_a is the first receive demodulation Threshold value, and threshold_b is the second receive demodulation Threshold value.
It can be seen that Δp is used to compensate the repetition number difference between r_a and r_b, and Δt is the difference between the reception demodulation thresholds of the first uplink channel and the second uplink channel.
The receiving demodulation threshold value of the uplink channel is issued through a system message such as SIB2 or SIB 1.
Optionally, the second uplink channel and the first uplink channel are the same channel or different channels.
