Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is 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 execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to 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 can be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.
As shown in fig. 1, an uplink transmission processing method according to an embodiment of the present invention is applied to a user equipment, and includes:
and 102, transmitting 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 to transmit 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 the first transmission parameter is used by the first uplink channel to successfully transmit the first information, so that the success rate of transmitting the second information on the second uplink channel by adopting the determined target power spectral density is improved, and the risk of transmission failure of the uplink channel is reduced.
Step 102 of transmitting the second information on the second uplink channel further obtains the target transmit power by using the target power spectral density determined in step 101, and completes transmission of the second information with the target transmit power.
Optionally, the first transmission parameter comprises a first repetition number, a first receive demodulation threshold value, and a first power spectral density; the second transmission parameter comprises a second repetition time and a second receiving demodulation threshold value;
as shown in fig. 2, step 101 includes:
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 is a configured receiving demodulation threshold 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 is a configured receiving demodulation threshold of the second uplink transmission channel.
Thus, according to step 201 and step 202, after a power spectral density compensation value is obtained from the first repetition number, the first receiving demodulation threshold, the second repetition number, and the second receiving demodulation threshold, the power spectral density compensation value is compensated for the first power spectral density, so as to obtain a target power spectral density suitable for the second information transmitted 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 has successfully transmitted the information, so that the transmitting 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 Δ P by a formula Δ P ═ α × 10log (R _ a/R _ B); wherein α is a power spectral density offset spread factor, R _ A is the first repetition number, and R _ B is the second repetition number;
calculating a second compensation value delta T through a formula delta T-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 follows that Δ P is used to compensate for the difference in the number of repetitions between R _ a and R _ B. If α is 1, R _ a is 8, and R _ B is 2, Δ P is 1 × 10log (8/2) is 6 dB. That is, it can be understood that since the repetition number of the second uplink channel is less than that of the first uplink channel, it is necessary to compensate for the loss of the repetition number in power.
And Δ T is the difference between the receiving demodulation thresholds of the first uplink channel and the second uplink channel. Wherein, if Threshold _ a is-110 dBm, and Threshold _ B is-112 dBm, then Δ T is-2 dB. That is, it can be understood that the receive demodulation threshold of the second uplink channel is lower, which needs to be reduced by 2dB in the transmit power spectral density.
The receiving demodulation threshold of the uplink channel is issued by a system message, such as system message 2(SIB2) or system message 1(SIB 1).
It should be noted that, in this embodiment, the second uplink channel is an uplink channel to which second information is to be sent, and the first uplink channel is an uplink channel to which first information is successfully sent before the second information is sent, so that the first uplink channel may be determined as an uplink channel to which information is sent last time only by time limitation; alternatively, the uplink channel for which the specific information is transmitted last is determined by further combining the definition of the first information.
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 both PUSCH (Physical Uplink Shared Channel); or, the first uplink Channel is a PRACH (Physical Random Access Channel), the second uplink Channel is a PUSCH, and so on.
Generally, NB-IoT (Narrow Band Internet of Things) is an important branch of the Internet of everything, and can support cellular data connection of low-power devices in a wide area network. The NB-IoT has the advantages of low power consumption, wide coverage, low cost, high capacity and the like, so that the NB-IoT is widely applied to various vertical industries. And NPRACH (Narrow Physical Random Access Channel) power control and NPUSCH (Narrow Physical Uplink Shared Channel) power control are two independent power control mechanisms, so the method of the embodiment of the present invention is applicable to an NB-IoT system, and optionally, both the first Uplink Channel and the second Uplink Channel are Narrow-band 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-based random access procedure.
Specifically, the first uplink channel for transmitting the MSG1 is NPRACH, and the second uplink channel for transmitting the MSG3 is NPUSCH.
For example, for NB-IoT, when MSG1 successfully transmits over NPRACH, the number of repetitions is 8, and the power spectral density is-3 dBm/15 Hz. NPUSCH transmitting MSG3 is repeated 2 times to satisfy power control requirements. When the receiving demodulation threshold of NPRACH of transmission MSG1 is set to-120 dBm and the receiving demodulation threshold of NPUSCH of transmission MSG3 is set to-118 dBm, the power spectral density of NPUSCH transmission MSG3 is-3 dBm/15KHz +10 log (8/2) + (-118 dBm- (-120dBm)) is set to-5 dBm/15KHz when α is 1.
Of course, the method of the embodiment of the present invention is also applicable to a PUSCH or PUCCH (Physical Uplink Control Channel) for transmitting Control information after the PUSCH for carrying user data is successfully transmitted. The Control Information may be UCI (Uplink Control Information), Uplink RRC (Radio Resource Control) Information, Uplink MR (Measurement Report), and the like.
Optionally, the first uplink channel is a PUSCH, and the second uplink channel is a PUSCH or a PUCCH.
Optionally, the first information is an MSG3 of a contention-based random access procedure, and the second information is a fifth signaling MSG5 of the contention-based random access procedure.
Specifically, the first uplink channel for transmitting the MSG3 is a PUSCH, and the second uplink channel for transmitting the MSG5 is a PUSCH.
For example, for 5G NR (New Radio, New air interface), when MSG3 is successfully transmitted over PUSCH, the number of repetitions is 8, and the power spectral density is-3 dBm/15 Hz. The PUSCH for transmitting MSG5 is repeated for 2 to satisfy the power control requirement. When the receive demodulation threshold of the PUSCH for transmitting MSG3 is set to-120 dBm and the receive demodulation threshold of the PUSCH for transmitting MSG5 is set to-120 dBm, the power spectral density of the PUSCH for transmitting MSG5 is-3 dBm/15KHz +10 log (8/2) + (-120 dBm- (-120dBm)) 3dBm/15KHz when α is 1.
In summary, in the method according to the embodiment of the present invention, the target power spectral density used by the second uplink channel to transmit the second information 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 the first transmission parameter is used by the first uplink channel to successfully transmit the first information, so that a success rate of transmitting the second information on the second uplink channel by using the determined target power spectral density is improved, and a transmission failure risk of the uplink channel is reduced.

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 to transmit 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 the first transmission parameter is used by the first uplink channel to successfully transmit the first information, so that the success rate of transmitting the second information on the second uplink channel by adopting the determined target power spectral density is improved, and the risk of transmission failure of the uplink channel is reduced.
Optionally, the first transmission parameter comprises a first repetition number, a first receive demodulation threshold value, and a first power spectral density; the second transmission parameter comprises a second repetition time and a second receiving demodulation threshold value;
the processing module comprises:

Thus, in the apparatus according to the embodiment of the present invention, after the first processing sub-module obtains a power spectral density compensation value from the first repetition number, the first receiving demodulation threshold, the second repetition number, and the second receiving demodulation threshold, the second processing sub-module compensates the first power spectral density with the power spectral density compensation value, so as to obtain a target power spectral density applicable to the second information transmitted 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 has successfully transmitted the information, so that the transmitting 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 comprises: a first compensation value and a second compensation value;

a second calculation unit for calculating a second compensation value Δ T by a formula Δ T ═ Threshold _ B-Threshold _ a; wherein Threshold _ a is the first receive demodulation Threshold value, and Threshold _ B is the second receive demodulation Threshold value.
Therefore, Δ P is used to compensate for the difference in the number of repetitions between R _ a and R _ B, and Δ T is the difference between the receiving demodulation thresholds of the first uplink channel and the second uplink channel.
The receiving demodulation threshold value of the uplink channel is issued by a system message such as SIB2 or SIB 1.
