Description

Power adjustment method, communication device, chip and module equipment thereof

Technical Field

The present application relates to the field of communications technologies, and in particular, to a power adjustment method, a communication device, a chip, and a module device thereof.

Background

When the terminal device operates in a Dual-connectivity (DC) scenario, the terminal device may access two Cell groups, namely, a Master Cell Group (MCG) and a Secondary Cell Group (SCG). At this time, the terminal device needs to share the transmission power between the MCG and the SCG, and the current power sharing method may be divided into dynamic power sharing and static power sharing. Taking dynamic power sharing as an example:

in an eNB and NR Dual Connection (EN-DC) scenario, i.e. MCG is an eNB base station and SCG is an NR base station, the following rules are followed:

if the terminal equipment is in the subframe i on the MCG ₁ Uplink transmission of uplink and terminal equipment in SCG time slot i ₂ Overlap of uplink transmissions on SCG and if in slot i of SCG ₂ Satisfies P on any part of _MCG (i ₁ )+P _SCG (i ₂ )＞P _Total If the SCG is not the same as the SCG, the terminal decreases the time slot i of the SCG ₂ The transmission power of the uplink channel corresponding to the upper overlapping part is made P _MCG (i ₁ )+P _SCG (i ₂ )≤P _Total . Wherein, P _MCG (i ₁ ) Subframe i on MCG for terminal equipment ₁ Uplink transmission power of P _SCG (i ₂ ) Time slot i on SCG for terminal equipment ₂ Uplink transmission power of P _Total Is the maximum transmission power of the terminal device.

In a NR and eNB dual link (NE-DC) scenario, where MG is the NR base station and SCG is the eNB base station, the following rules are followed:

if the terminal is in time slot i on MCG ₁ Uplink transmission on SCG and terminal on SCG subframe i ₂ Overlap of uplink transmissions on the MCG and if in time slot i of the MCG ₁ Satisfies P on any part of _MCG (i ₁ )+P _SCG (i ₂ )＞P _Total Then the terminal lowers the time slot i of MCG ₁ The transmission power of the uplink channel corresponding to the upper overlapping part is made P _MCG (i ₁ )+P _SCG (i ₂ )≤P _Total . Wherein, P _MCG (i ₁ ) Time slot i on MCG for terminal equipment ₁ Uplink transmission power of P _SCG (i ₂ ) Subframe i on SCG for terminal equipment ₂ Uplink transmission power of P _Total Is the maximum transmission power of the terminal device.

Currently, the NR system needs to enhance uplink coverage, and the enhancing technique can be adopted in the NR system, for example: joint channel measurement techniques. A time window may be introduced when making the joint channel measurements. When the base station side performs joint channel detection in a time window, the terminal device needs to ensure that the transmission power of each uplink channel on all time slots in the time window is kept consistent. However, if the MCG overlaps with the uplink channel of the SCG in the time window, and the sum of the MCG transmission power and the SCG transmission power is greater than the maximum transmission power of the terminal device, it cannot be guaranteed that the transmission power of each uplink channel in the whole time window is consistent.

Detailed Description

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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.

Referring to fig. 1, fig. 1 is an architecture diagram of a communication system according to an embodiment of the present disclosure. As shown in fig. 1, the communication system may include a terminal device 101, a first network device 102, and a second network device 103. The terminal device 101 is an entity, such as a mobile phone, on the user side for receiving or transmitting signals. A terminal device may also be referred to as a terminal (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc. The terminal device may be a mobile phone (mobile phone), a wearable device, a tablet (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in remote surgery (remote surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in city (city), a wireless terminal in smart home (smart home), a device for supporting enhanced Machine-Type communication (eMTC), and/or a Long Term Evolution (LTE) terminal supporting universal mobile communication technology, and so on. The embodiment of the present application does not limit the specific technology and the specific device form adopted by the terminal device.

The first network device 102 may be a network device corresponding to an MCG accessed by the terminal device 101, and the second network device 103 may be a network device corresponding to an SCG accessed by the terminal device 101. It should be noted that the difference between the network devices corresponding to the MCG and the SCG shown in fig. 1 is only for example and does not constitute a limitation to the embodiment of the present application. Optionally, the network devices corresponding to the MCG and the SCG in fig. 1 may also be the same network device.

The network devices (such as the first network device 102 and the second network device 103) are entities on the network side for transmitting or receiving signals. For example, the network device may be an evolved NodeB (eNB), a transmission point (TRP), a next generation base station (gNB) in the NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices.

It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems. For example: a Long Term Evolution (LTE) system, a fifth generation (5 th generation, 5G) mobile communication system, and a 5G New Radio (NR) system. Optionally, the method of the embodiment of the present application is also applicable to various future communication systems, for example, a 6G system or other communication networks.

Referring to fig. 2, fig. 2 is a flowchart of a power adjustment method according to an embodiment of the present disclosure. The power adjustment method may be implemented by the terminal device, or may be implemented by a chip in the terminal device. As shown in fig. 2, the power adjustment method includes, but is not limited to, the following step S201.

Step S201, if the time domain resources of a first uplink channel in a first cell group and a second uplink channel in a time window of a second cell group are overlapped, the sum of the first transmission power of the first uplink channel and the second transmission power of the second uplink channel is greater than the maximum transmission power of the terminal equipment, and the interval between the first time and the second time is greater than a first preset time, the transmission power of the second uplink channel in the time window is reduced to a third transmission power; the sum of the third transmit power and the first transmit power is less than or equal to the maximum transmit power of the terminal device, the first time is associated with a first uplink channel, the second time is associated with a time window, and the time window is a continuous time in a time domain.

As can be seen from the foregoing, the terminal device provided in this embodiment of the present application operates in a DC scenario, and therefore the first cell group may be an MCG, which may be a cell group in which an eNB base station is located; the second cell group may be an SCG, and the SCG may be a cell group in which the NR base station is located. Optionally, the first cell group may also be an SCG, and the SCG may be a cell group in which the eNB base station is located; the second cell group may be an MCG, and the MCG may be a cell group in which the NR base station is located. Optionally, the first cell group may be an MCG, and the MCG may be a cell group in which an NR base station is located; the second cell group may be an SCG, and the SCG may be a cell group in which the NR base station is located. This is not limited by the present application.

Because of the presence of MCG and SCG, there may be two or more uplink channels, such as the first uplink channel and the second uplink channel described above. When the two uplink channels are transmitted in parallel, the two uplink channels may partially overlap in the time domain. As shown in fig. 3, taking the second uplink channel having four uplink channels as an example, the second uplink channel 1, the second uplink channel 2, the second uplink channel 3, and the second uplink channel 4. As can be seen from fig. 3, the first uplink channel overlaps with the second uplink channel 2 in the time domain.

It should be noted that, like the second uplink channel, the first uplink channel may also have multiple first uplink channels, which is not described herein again. It should be further noted that, the overlapping portion of the first uplink channel and the second uplink channel in fig. 3 is only used for example, and does not limit the embodiment of the present application.

In an implementation manner, the first Uplink Channel may be a Physical Uplink Shared Channel (PUSCH). Optionally, the first Uplink Channel may also be a Physical Uplink Control Channel (PUCCH). Optionally, the first uplink Channel may also be a Physical Random Access Channel (PRACH). Optionally, the first uplink channel may also be a Sounding Reference Signal (SRS).

In an implementation manner, the second uplink channel may be a PUSCH, similarly. Optionally, the second uplink channel may also be a PUCCH. Optionally, the second uplink channel may also be a PRACH. Optionally, the second uplink channel may also be an SRS.

The time window is a concept of a time domain. As shown in fig. 3A, a time window may be understood as a continuous time in the time domain, and the time window may include one or more uplink channels. The time window shown in fig. 3A may include four second uplink channels of the second uplink channels. It should be noted that the width of the time window may determine the length of the intercepted channel, and the application does not limit the width of the time window.

Optionally, as shown in fig. 3A, the starting position of the time window may be the same as the position of the first symbol of the second uplink channel 1, or may be earlier or later than the position of the first symbol of the second uplink channel 1, as shown in fig. 3B and fig. 3C, which is not limited in this application.

In one implementation, the starting position of the time window may be configured in advance by the base station, or determined according to a parameter indicated or configured by a higher layer or a physical layer, which is not limited in this application. By configuring the position of the time window in advance, the terminal device can know the position of the time window in advance, thereby facilitating determination of whether the second uplink channel within the time window overlaps with the first uplink channel.

In one implementation, the terminal device may receive Downlink Control Information (DCI), and the DCI may be used to schedule or associate the first uplink channel. In other words, the terminal device may obtain the position of the first uplink channel indicated in the DCI in the time domain by receiving the DCI, so as to determine whether the first uplink channel and the second uplink channel overlap.

In one implementation, before transmitting the first uplink channel, the terminal device may determine the transmission power of the first uplink channel, that is, the first transmission power. Optionally, the terminal device may determine the first transmission power according to a parameter indicated or configured by a higher layer or a physical layer. Optionally, the determination of the second transmission power of the second uplink channel may refer to a determination manner of the first transmission power, which is not described herein again. Optionally, the terminal device determines the first transmission power or the second transmission power according to TS38.213, section 7. Optionally, the terminal device determines the first transmission power according to TS36.213 section 5, and the terminal device determines the second transmission power according to TS38.213 section 7. Optionally, the terminal device determines the first transmission power according to TS38.213, section 7, and the terminal device determines the second transmission power according to TS36.213, section 5. Optionally, the terminal device determines the first transmission power or the second transmission power according to TS36.213, section 5.

In one implementation, the maximum transmission power of the terminal device is a maximum transmission power configured in a DC scenario. Alternatively, its specific definition may refer to TS 38.101-3-8-3.

In an implementation manner, the first time may be an end time of a last symbol of the downlink control information DCI for scheduling the first uplink channel. Since the DCI may include a plurality of symbols, the end time of the last symbol of the DCI may also be understood as the time when the complete DCI is received.

By defining the first time as the ending time of the last symbol of the DCI, more time can be reserved for the terminal device, so that more time is won for the terminal device to process the transmission power of the second uplink channel in the time window.

In an implementation manner, the first time may also be a time before a first preset time of a first symbol of the first uplink channel. The first preset time may be understood as the shortest time for the terminal device to process the DCI and/or prepare to send the uplink channel. Alternatively, the first preset time may be understood as the shortest time for the terminal device to prepare to send the uplink channel. Optionally, the first preset time is T defined by 3GPP _proc，2 ，T _proc，CSI ，

And

one value of (a). Optionally, the first preset time is T defined by 3GPP _proc，2 ，T _proc，CSI ，

And

the largest value of (1).

By defining the first time as the time before the first preset time of the first symbol of the first uplink channel, the time for processing the DCI of the first uplink channel and/or preparing to transmit the uplink channel can be reserved for the terminal device, so that the terminal device can be guaranteed to have enough time to process the transmission power of the first uplink channel regardless of whether the terminal device has time to process the transmission power of the second uplink channel within the time window.

In one implementation, the first preset time may be determined by a preparation time of the first uplink channel. Optionally, the first preset time may also be determined by a preparation time of the second uplink channel. Optionally, the first preset time may also be configured by a higher layer signaling, or the first preset time is predefined by a protocol. It can be understood that the first preset time can be configured through a high-level signaling, so that the value of the first preset time is more flexible; the first preset time can be set in advance through protocol preset rules, so that transmission resources are saved.

As can be seen from the above, the first time may take a value within a range. As shown in fig. 4A, any time from the end time of the last symbol of DCI to the first preset time of the first symbol of the first uplink channel may be the first time.

In an implementation manner, the second time may be a starting time corresponding to a first symbol of a first second uplink channel within a time window. Note that, as shown in fig. 4B, in this implementation, the starting position of the time window may be the position shown in fig. 3A. That is, the starting position of the time window is the starting position corresponding to the first symbol of the first second uplink channel in the time window.

By defining the second time as the starting time corresponding to the first symbol of the first second uplink channel in the time window, more time can be reserved for the terminal device. Since the second uplink channel is not transmitted in the time window, more time can be won for the terminal device to process the transmission power of the second uplink channel in the time window before the second uplink channel is transmitted.

In one implementation, the second time may be a starting time corresponding to a first symbol in the time window. It should be noted that, in this implementation, as shown in fig. 4C, the starting position of the time window may correspond to the position shown in fig. 3B; as shown in fig. 4D, the starting position of the time window may correspond to the position shown in fig. 3C.

By defining the second time as the starting time corresponding to the first symbol in the time window, the range of unchanged transmission power can be ensured to be expanded, so that the transmission power in the time window is ensured to be unchanged to the maximum extent.

As shown in fig. 4E, assuming that the first time is an ending time of the last symbol of the DCI and the second time is a starting time corresponding to the first symbol of the first second uplink channel in the time window, and assuming that an interval between the first time and the second time is T, if T is greater than the first preset time, the terminal device decreases the transmission power of the second uplink channel in the time window to a third transmission power.

The third transmission power may be determined by the maximum transmission power of the terminal device and the first transmission power of the first uplink channel. Specifically, the third transmit power may be determined according to a difference between the maximum transmit power of the terminal device and the first transmit power. It can be understood that, the value of the third power may be smaller than or equal to the difference between the maximum transmission power of the terminal device and the first transmission power, so that the sum of the third transmission power and the first transmission power is smaller than or equal to the maximum transmission power of the terminal device.

In an implementation manner, the reducing the transmission power of the second uplink channel in the time window to the third transmission power may include: and reducing the transmission power of all the second uplink channels in the time window to third transmission power.

Since the second uplink channel in the time window may include a plurality of second uplink channels, as shown in fig. 4E, the second uplink channel in the time window may include four second uplink channels. If the transmission power of the second uplink channel 2 in the overlapping portion is reduced to the third transmission power, the transmission power of the second uplink channel 2 in the time window will be different from the transmission power of the second uplink channel 1, the second uplink channel 3, and the second uplink channel 4. Therefore, by reducing the transmission power of all the second uplink channels in the time window to the third transmission power, it is possible to ensure that the transmission power of all the second uplink channels in the time window is the same. Therefore, the base station can perform joint channel estimation by using the demodulation reference signals of the second uplink channels, and the channel estimation performance is improved.

In an implementation manner, the reducing the transmission power of the second uplink channel in the time window to the third transmission power may include: and if the difference between the second transmission power and the third transmission power is smaller than the first threshold, reducing the transmission power of the second uplink channel in the time window to the third transmission power.

The first threshold may be configured by higher layer signaling, or the first threshold may be predefined by a protocol. The unit of the first threshold may be dB, and the value of the first threshold may be a natural number.

In one implementation, the method further includes: and if the difference between the second sending power and the third sending power is larger than the first threshold value, giving up the sending of the second uplink channel in the time window.

It should be noted that, if the second transmission power needs to be reduced by too much, the reception and/or demodulation of the second uplink channel by the base station may be affected. In this case, therefore, the transmission of the second uplink channel 2 within the above-mentioned time window may be abandoned. Optionally, the sending of all the second uplink channels in the time window may also be abandoned, which is not limited in this application.

By giving up the transmission of the second uplink channel within the time window, when the quality of the second uplink channel cannot be guaranteed, the transmission power of the overlapping part of the second uplink channel and the first uplink channel is reduced, so that the sum of the transmission powers of the overlapping part of the second uplink channel and the first uplink channel within the time window is less than or equal to the maximum transmission power of the terminal device. Meanwhile, by giving up the transmission of the second uplink channel in the time window, the transmission power of other second uplink channels in the time window can be ensured to be kept unchanged.

In one implementation, the method further includes: if the time domain resources of the first uplink channel and the second uplink channel in the time window of the second cell group are overlapped, the sum of the first sending power of the first uplink channel and the second sending power of the second uplink channel is larger than the maximum sending power of the terminal equipment, and the interval between the first moment and the second moment is smaller than the first preset time, the terminal equipment reduces the first sending power to fourth sending power; and the sum of the fourth transmission power and the transmission power of the second uplink channel in the time window is less than or equal to the maximum transmission power of the terminal equipment.

As shown in fig. 4F, similarly, taking as an example that the first time is an end time of the last symbol of the DCI, and the second time is a start time corresponding to the first symbol of the first second uplink channel in the time window, assuming that the interval between the first time and the second time is T, if T is less than the first preset time, the terminal device reduces the first transmission power to the fourth transmission power.

As can be seen from fig. 4F, when T is less than the first preset time, that is, when the terminal device has no time to process DCI of the first channel and/or prepare the first uplink channel, since the second transmission power in the time window is already determined, in order to ensure that the transmission powers in the time window are consistent, when the terminal device has time to process the first transmission power, the first transmission power may be reduced to the fourth transmission power, so that the sum of the transmission powers of the overlapping portions of the second uplink channel and the first uplink channel in the time window is less than or equal to the maximum transmission power of the terminal device.

Specifically, for a manner of reducing the first transmission power to the fourth transmission power, reference may be made to the description in any implementation manner of reducing the second transmission power in the time window to the third transmission power, and details of this application are not repeated herein.

By implementing the method provided by the embodiment of the present application, when the time domain resources of the first uplink channel and the second uplink channel in the time window of the second cell group are overlapped, and the sum of the first transmission power of the first uplink channel and the second transmission power of the second uplink channel is greater than the maximum transmission power of the terminal device, the transmission power of the uplink channel that needs to be reduced may be determined by judging whether the interval between the first time and the second time is greater than the first preset time, so that the transmission power of each uplink channel in the whole time window is kept consistent.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a communication device according to an embodiment of the present disclosure. The device may be a terminal device, or a device in the terminal device, or a device capable of being used in cooperation with the terminal device. The communication device shown in fig. 5 may comprise a processing unit 501. The processing unit 501 is configured to perform data processing. Wherein:
