Description

Wireless communication method, terminal device and network device

Technical Field

The embodiment of the application relates to the field of communication, and more particularly relates to a wireless communication method, terminal equipment and network equipment.

Background

When the terminal works under the frequency band combinations of carrier aggregation (Carrier Aggregation, CA), E-UTRA and NR Dual connectivity (E-UTRA-NR Dual Connectivity, EN-DC), dual Connectivity (DC) and the like, the total transmitting power of the terminal on a plurality of carriers cannot exceed the value of Pcmax; where Pcmax is the maximum transmission power configurable by the terminal, it means that the total transmission power on all carriers cannot exceed this value for a band combination.

When the transmit power on one carrier increases, it means that the transmit power available to the other carriers will decrease. In other words, when one carrier occupies all of the transmit power, no transmit power will be available on the other carriers. For example, in a combination of bands such as CA, it is assumed that the terminal needs to transmit on the primary carrier (Primary Cell Component, PCC) and the secondary carrier (Secondary Cell Component, SCC) simultaneously, but the primary carrier occupies most of the power, resulting in that the transmit power on the secondary carrier is too small to maintain the uplink, which would lead to a case where the SCC link is disconnected, i.e. only the PCC is operating. In contrast, if both the PCC and the SCC are able to maintain the link and communicate, the overall throughput of the data transmission will be better than if the PCC were transmitting alone.

In addition, the current New air interface (NR) will use power for the carrier with higher priority first under the frequency band combination, and then the remaining power is allocated to the carrier with lower priority for use. Thus, when the high priority carrier occupies most or even all of the power, the low priority carrier will break the connection. For example, in a combination of frequency bands such as CA, the priority of the PCC may be lower than the priority of the SCC, however, if the transmitting power on the PCC cannot keep the normal connection of the link, both the PCC and the SCC will be dropped, which reduces the reliability of data transmission.

Accordingly, there is a need in the art for a wireless communication method that can improve throughput and reliability of data transmission.

Detailed Description

The following description of the technical solutions according to the embodiments of the present application will be given with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

FIG. 1 is an example of a system framework of an embodiment of the present application.

As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air interface. Multi-service transmission is supported between terminal device 110 and network device 120.

It should be understood that embodiments of the present application are illustrated by way of example only with respect to communication system 100, and embodiments of the present application are not limited thereto. That is, the technical solution of the embodiment of the present application may be applied to various communication systems, for example: long term evolution (Long Term Evolution, LTE) system, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), internet of things (Internet of Things, ioT) system, narrowband internet of things (Narrow Band Internet of Things, NB-IoT) system, enhanced Machine-type-Type Communications (eMTC) system, 5G communication system (also referred to as New Radio (NR) communication system), or future communication system, etc.

In the communication system 100 shown in fig. 1, the network device 120 may be an access network device in communication with the terminal device 110. The access network device may provide communication coverage for a particular geographic area and may communicate with terminal devices 110 (e.g., UEs) located within the coverage area.

The network device 120 may be an evolved base station (Evolutional Node B, eNB or eNodeB) in a long term evolution (Long Term Evolution, LTE) system, or a next generation radio access network (Next Generation Radio Access Network, NG RAN) device, or a base station (gNB) in a NR system, or a radio controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or the network device 120 may be a relay station, an access point, a vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

Terminal device 110 may be any terminal device including, but not limited to, a terminal device that employs a wired or wireless connection with network device 120 or other terminal devices.

For example, the terminal device 110 may refer to an access terminal, user Equipment (UE), subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or User Equipment. An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, an IoT device, a satellite handset, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA), a handset with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network or a terminal device in a future evolution network, etc.

The terminal Device 110 may be used for Device-to-Device (D2D) communication.

The wireless communication system 100 may further comprise a core network device 130 in communication with the base station, which core network device 130 may be a 5G core,5gc device, e.g. an access and mobility management function (Access and Mobility Management Function, AMF), further e.g. an authentication server function (Authentication Server Function, AUSF), further e.g. a user plane function (User Plane Function, UPF), further e.g. a session management function (Session Management Function, SMF). Optionally, the core network device 130 may also be a packet core evolution (Evolved Packet Core, EPC) device of the LTE network, for example a session management function+a data gateway (Session Management Function + Core Packet Gateway, smf+pgw-C) device of the core network. It should be appreciated that SMF+PGW-C may perform the functions performed by both SMF and PGW-C. In the network evolution process, the core network device may also call other names, or form new network entities by dividing the functions of the core network, which is not limited in this embodiment of the present application.

Fig. 1 exemplarily illustrates one base station, one core network device, and two terminal devices, alternatively, the wireless communication system 100 may include a plurality of base station devices and each base station may include other number of terminal devices within a coverage area, which is not limited by the embodiment of the present application.

It should be understood that devices having communication functions in the network/system according to the embodiments of the present application may be referred to as communication devices. Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 120 and a terminal device 110 with communication functions, where the network device 120 and the terminal device 110 may be the devices described above, and are not described herein again; the communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

When the transmit power on one carrier increases, it means that the transmit power available to the other carriers will decrease. In other words, when one carrier occupies all of the transmit power, no transmit power will be available on the other carriers.

As shown in fig. 2, under the combination of bands such as CA, it is assumed that the terminal needs to transmit on the primary carrier (Primary Cell Component, PCC) and the secondary carrier (Secondary Cell Component, SCC) simultaneously, but the primary carrier occupies most of the power, so that the transmit power on the secondary carrier is too small to maintain the uplink, which would lead to the case that the SCC link is disconnected, that is, only the PCC is in operation. This is common in networks, where network devices configure Resource Block (RB) resources and schedule modulation and coding strategies (Modulation and Coding Scheme, MCS) according to signal quality on the carrier. For example, when the terminal device is in the cell center and the signal quality of the PCC is better, the network device will allocate more RBs while scheduling higher MCSs, so that the terminal device transmits very high power. At this time, the SCC may use only the remaining power because of its lower priority than the PCC, which makes it difficult to maintain the link and causes SCC link failure.

In contrast, if both the PCC and the SCC are able to maintain the link and communicate, the overall throughput of the data transmission will be better than if the PCC were transmitting alone.

In addition, the relative priorities among the multiple carriers are affected by a number of factors, including the type of channel transmitted on the carrier (e.g., PUSCH and PUCCH are prioritized over SRS, etc.), the traffic content carried by the channel (e.g., PUSCH and PUCCH are prioritized with respect to whether control information or traffic information is carried thereon, etc.), the priority directly indicated by the network device (e.g., the network device signals whether the carrier is a high priority or a low priority), etc. Thus, when the SCC has a higher priority, the terminal device will divide most of the power to the SCC transmissions, which will cause the PCC to drop, so that the terminal device will experience a problem of disconnection from the network, since the SCC will drop if the PCC drops.

That is, the current New air interface (NR) will use power for the carrier with higher priority first under the frequency band combination, and then allocate the remaining power to the carrier with lower priority for use. Thus, when the high priority carrier occupies most or even all of the power, the low priority carrier will break the connection. For example, in a combination of frequency bands such as CA, the priority of the PCC may be lower than the priority of the SCC, however, if the transmitting power on the PCC cannot keep the normal connection of the link, both the PCC and the SCC will be dropped, which reduces the reliability of data transmission.

Based on the above, the embodiment of the application provides a wireless communication method, a terminal device and a communication device, which can improve the throughput and the reliability of data transmission.

Of course, in other alternative embodiments, the at least one first carrier includes a carrier of the plurality of carriers having a priority index of a second value. Alternatively, the second value may be 0, i.e. the at least one first carrier may also comprise a low priority carrier.

In some embodiments, the priorities of the plurality of carriers are initial priorities when the network device configures the plurality of carriers for the terminal device.

In some embodiments, the first threshold value or the second threshold value is configured by a network device, or the first threshold value or the second threshold value is determined by the terminal device, or the first threshold value or the second threshold value is predefined.

It should be noted that, in the embodiment of the present application, the "predefining" may be implemented by pre-storing corresponding codes, tables or other manners that may be used to indicate relevant information in devices (including, for example, terminal devices and network devices), and the present application is not limited to the specific implementation manner thereof. Such as predefined, may refer to what is defined in the protocol. Alternatively, the "protocol" may refer to a standard protocol in the communication field, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied to a future communication system, which is not particularly limited by the present application.

In other words, in case the terminal device is configured with the at least one first threshold and the second threshold, the transmit power on the at least one first carrier may be determined preferentially based on the at least one first threshold for the at least one first carrier. Of course, in other alternative embodiments, for each first carrier of the at least one first carrier, the transmit power on the first carrier may also be determined based on a minimum value of the first threshold value and the second threshold value corresponding to the first carrier, which is not limited in more detail in the present application.

Optionally, the first configuration information is further used to configure the plurality of carriers for the terminal device.

In other words, the first configuration information is used not only for configuring the plurality of carriers, but also for configuring the at least one first threshold value and/or the second threshold value.

Optionally, the method 200 may further include:

Receiving second configuration information;

the second configuration information is used for configuring the plurality of carriers for the terminal equipment.

In other words, the configuration information for configuring the plurality of carriers is different from the configuration information for configuring the at least one first threshold value and/or the second threshold value. Alternatively, the configuration information for configuring the plurality of carriers is independent of the configuration information for configuring the at least one first threshold value and/or the second threshold value.

Optionally, the second configuration information is carried in a radio resource control (Radio Resource Control, RRC).

Optionally, the at least one second carrier is a carrier of the plurality of carriers and the priority index is a first value at a first time.

Optionally, the first value is 1.

Alternatively, a priority index of 1 indicates a high priority.

In other words, the at least one second carrier is a high priority carrier of the plurality of carriers and at a first time instant.

Of course, in other alternative embodiments, the at least one second carrier is a carrier of the plurality of carriers and the priority index is a second value at the first time. Alternatively, the second value may be 0, i.e. the at least one second carrier is a low priority carrier of the plurality of carriers and at the first time instant.

Optionally, the at least one second carrier is the plurality of carriers.

In other words, the second threshold value may be activated or deactivated for the terminal device, or may be activated or deactivated for the first cell.

In some embodiments, the S210 may include:

based on the spatial propagation loss, transmit power on the plurality of carriers is determined.

Alternatively, the terminal device may obtain the received signal quality (such as strength or signal-to-noise ratio SINR) on each carrier by measuring the downlink signals on the multiple carriers, and based on this, the spatial propagation loss may be obtained.

As an example, if the propagation loss is greater than or equal to a third threshold value and the remaining available transmit power of the terminal device is greater than or equal to the transmit power scheduled by the network device, the transmit power scheduled by the network device may be determined to be the transmit power on the primary carrier of the plurality of carriers. And if the propagation loss is greater than or equal to a third threshold value and the remaining available transmission power of the terminal device is smaller than the transmission power scheduled by the network device, determining the remaining available transmission power as the transmission power on the main carrier in the multiple carriers, or determining the transmission power on the main carrier to be smaller than the transmission power scheduled by the network device.

In some embodiments, the first indication information is used to indicate that the transmission power on a third carrier of the plurality of carriers is too low, or the first indication information is used to indicate that the signal quality on the third carrier is less than or equal to a preset threshold, or the first indication information is used to indicate that the transmission power on the third carrier of the plurality of carriers is increased.

Alternatively, the network device may obtain the received signal quality (such as strength or signal-to-noise ratio SINR) on each carrier by measuring the uplink signals on the multiple carriers, and based on this, the spatial propagation loss may be obtained.

Optionally, the S210 may include:

if the index of the priority of the third carrier is a first value or if the third carrier is a main carrier of the plurality of carriers, increasing the transmission power on the third carrier and reducing the transmission power on some or all of the plurality of carriers except the third carrier.

Optionally, the S210 may include:

The following describes aspects of the application in connection with specific embodiments.

Example 1:

in this embodiment, the terminal device may determine the transmit power on the multiple carriers based on at least one first threshold value corresponding to the at least one first carrier, respectively. Wherein the at least one first carrier comprises a high priority carrier of the plurality of carriers. That is, the network device configures an absolute power limit or a relative power limit for the high priority carrier such that the high priority carrier does not occupy too much transmit power to cause insufficient transmit power on the low priority carrier. For example, the plurality of carriers initially configured by the network device have a determined order of priority, and, illustratively, in EN-DC combinations, the LTE carrier has a higher priority as the primary carrier than the NR secondary carrier.

The network device configures the maximum transmit power limit pow_cc, which may be an absolute power limit or a relative power limit, for the high priority carriers, respectively.

The absolute power limit refers to the maximum transmit power value that the carrier can transmit. For example, for a terminal device in a frequency band combination, the total maximum transmission power is 26dBm, and the absolute power limit value pow_cc on the primary carrier may be optionally configured to be 23dBm, that is, at least 23dBm of transmission power may be remained for the secondary carrier to transmit. The relative power limit refers to a back-off value of the maximum transmission power that the carrier can transmit compared to the total maximum transmission power of the terminal multi-carrier, such as {1db,2db,3db,4db,5db }. For example, for a terminal device under a band combination, the total maximum transmission power is 26dBm, the relative power limit value pow_cc on the primary carrier may be selectively configured to be 3dB, and the maximum power that can be transmitted by the primary carrier is 26dBm-3 db=23 dBm. That is, at least 26dBm-23dBm = 23dBm of transmit power may remain for use by the secondary carrier transmission.

In a specific implementation, the pow_cc configured by the network device may be configured to the terminal device together when the network device configures the carrier for the terminal device through RRC signaling, or may be configured to the terminal device independently through RRC signaling.

In other words, the above-mentioned manner of using pow_cc of the network configuration may include the following two manners:

mode 1:

it may be that after configuring the carrier and the pow_cc, the pow_cc is also validated when the carrier is activated, and the pow_cc is also invalidated when the carrier is deactivated.

Mode 2:

after the carrier and the pow_cc are configured, the pow_cc will not take effect immediately when the carrier is activated, but the network device can activate or deactivate the pow_cc through MAC signaling or physical layer DCI instructions; the pow_cc also fails when the carrier is deactivated. This approach includes both limit configuration and the pow_cc activation and deactivation steps.

Correspondingly, after receiving the pow_cc configured by the network device, the terminal device controls the transmitting power based on the pow_cc during actual power transmission, so as to ensure that the carrier wave with high priority does not exceed the pow_cc.

Example 2:

in this embodiment, the terminal device may determine the transmit power on the multiple carriers based on at least one first threshold value corresponding to the at least one first carrier, respectively. Wherein the at least one first carrier comprises a portion of or all of the plurality of carriers. That is, the multiple carriers initially configured by the network have no determined priority, for example, the priority among carriers in the CA combination is related to the channel and the service type carried on the carrier at a certain moment, and also related to the priority directly indicated by the network device.

Since the network device cannot predict the priority relative relationship between the carriers at a certain time, the network device needs to configure a maximum transmit power limit value pow_cc, which may be an absolute power limit value or a relative power limit value, for each carrier or a part of carriers, respectively.

mode 1:

Mode 2:

For example, the network device activates pow_cc on a certain carrier, which may be decided based on the priority order of the carrier at a certain moment. The network device can select to activate the pow_cc on the high priority carrier at the current moment; when the carrier becomes low priority at the next time, the network device may choose to deactivate pow_cc on the carrier. Of course, the network device may also activate or deactivate pow_cc on the low priority carrier at the same time when pow_cc on the high priority carrier is activated or deactivated.

Correspondingly, after receiving the pow_cc configured by the network device, the terminal device controls the transmitting power based on the activated pow_cc in the actual power transmitting process, so as to ensure that the carrier wave with high priority does not exceed the pow_cc.

Example 3:

in this embodiment, the network device configures a maximum transmit power limit value pow_cell applicable to all multi-carrier transmit terminals in the cell, where the pow_cell may be an absolute power limit value or a relative power limit value, and all carriers cannot transmit in the cell beyond the pow_cell regardless of the priority among the carriers. The use of pow_cell may include two ways, as pow_cc, namely immediate validation after configuration, or activation after configuration is required to be validated.

Illustratively, the maximum transmit power of the terminal device is 26dBm, then when the network device is configured with a pow_cell: if the pow_cell is an absolute power limit, the terminal device cannot transmit power over the pow_cell on any of the multiple carriers; if pow_cell is a relative power limit, then the terminal device cannot exceed 26dBm-pow_cell no matter on which multicarrier it transmits.

In this embodiment, the network device does not need to configure transmit power limits for multiple carriers on all terminal devices in the cell, so that complexity can be reduced to the greatest extent. Further, the pow_cell and the pow_cc may be used in combination, that is, when the network device configures the pow_cell and the pow_cc at the same time, the terminal device may perform control of the maximum transmit power according to the pow_cc, or perform control of the maximum transmit power according to the minimum value in the pow_cell and the pow_cc, thereby reducing complexity while maintaining a certain flexibility.

Example 3:

in this embodiment, the terminal device may autonomously control the transmit power, that is, the terminal device may autonomously determine whether the transmit power on a certain carrier is too low, for example, if the spatial propagation loss is greater than a certain threshold, the terminal device may autonomously adjust the transmit power allocation between carriers.

When the uplink propagation loss is higher than a certain threshold, the terminal equipment should ensure the transmission power of the PCC, and allocate the residual power to the SCC for use, if the carrier with higher priority in the multiple auxiliary carriers is provided, the transmission power requirement of the carrier is preferably ensured.

When the uplink propagation loss is lower than a certain threshold, the terminal device is located at a non-cell edge position, and at this time, the terminal device should keep the maximum available transmission power of the PCC and the maximum available transmission power of the SCC the same, or the terminal device should keep the maximum available power density of the PCC and the maximum available power density of the SCC the same, or the terminal device should keep the maximum available transmission power of the PCC and the central operation frequency of the PCC in direct proportion, or the terminal device should keep the maximum available transmission power of the SCC in direct proportion to the central operation frequency of the SCC, or the terminal device should satisfy the following relationship:

M _P /Ms＝F _P /F _S ；

Optionally, the certain threshold may be a value configured by the network device, or may be a value autonomously determined by the terminal device.

In this embodiment, by autonomously determining whether the transmission power on a certain carrier is too low, the terminal device can dynamically adjust the transmission power according to the service requirement.

Example 4:

in this embodiment, when the network device indicates that the transmitting power of the terminal device on a certain carrier is too low, the terminal device may be triggered to adjust the transmitting power allocation between the carriers.

Specifically, the network device receives the multicarrier transmission signal of the terminal device, and measures and obtains the quality (such as strength or signal-to-noise ratio SINR) of the reception signal on each carrier. When the quality of the received signal on a certain carrier is lower than a certain threshold, the network device can send indication information that the power of the certain carrier is too low to the terminal device through RRC or MAC CE.

Correspondingly, after receiving the indication information of the too low power, the terminal equipment further determines the power priority of the certain carrier and adjusts the transmission power: when the high priority carrier or the main carrier receives the indication information of the too low power, the terminal equipment should increase the transmitting power of the carrier so as to avoid the disconnection of the link; when the low priority carrier (non-primary carrier) receives the power-down indication information, the terminal device should appropriately increase the low priority carrier power while ensuring that the high priority carrier and the primary carrier do not disconnect the link.

In this embodiment, by means of a network device indication, the terminal device can dynamically adjust the transmitting power according to the service requirement.

Based on the scheme, the application provides a method for adjusting the transmitting power of the terminal equipment on multiple carriers, so as to avoid the problem of carrier disconnection of the terminal equipment. In one implementation, the network device may configure a first threshold value on a high priority carrier based on carrier priority, reserving power for a low priority carrier or a primary carrier. In another implementation, the network device may also configure a second threshold value applicable to all multi-carrier transmitting terminal devices within the cell, i.e. all carriers cannot be transmitted within the cell beyond said second threshold value, irrespective of the priority between the carriers. Of course, the terminal device autonomously determines whether the transmission power on a certain carrier is too low (e.g. based on the spatial propagation loss being greater than a certain threshold), or indicates, through the network device, that the transmission power of the terminal device on a certain carrier is too low, and the terminal device adjusts the transmission power allocation between the carriers.
