Description

Wireless communication method, terminal device and network device

Technical Field

The embodiments of the present application relate to the field of communications, and more particularly, to a wireless communication method, a terminal device, and a network device.

Background

In the existing fifth Generation mobile communication technology (5-Generation, 5G) New air interface (NR) system, a terminal device may be configured with a primary physical uplink control channel (Physical Uplink Control Channel, PUCCH) cell Group (cell Group, CG) and a secondary PUCCH cell Group (2 nd PUCCH Group); wherein the primary PUCCH Cell group includes a special Cell (SPCell) and one or more Secondary cells (scells), and channel state information (Channel State Information, CSI) reports of serving cells in the primary PUCCH Cell group are all reported through the SPCell, and the serving cells may be activated scells; the secondary PUCCH cell group comprises a PUCCH SCell and one or more SCells, and the CSI reports of the service cells in the secondary PUCCH cell group are all reported through the PUCCH SCell.

That is, when a serving cell needs to report a CSI report, the terminal device may report the CSI report of the serving cell on the SPCell in the primary PUCCH cell group where the serving cell is located or on the PUCCH SCell in the secondary PUCCH cell group where the SCell is located.

It follows that if one SCell in the primary PUCCH cell group is an SCell to be activated, the terminal device may report the CSI report of that SCell before activating that SCell, since the SPCell is always in an activated state, even though that SCell has not yet been activated. However, if the PUCCH SCell is an SCell to be activated, the terminal device can send the SCI report of the PUCCH SCell through the activated PUCCH SCell only after receiving the activation command of the PUCCH SCell and the PUCCH SCell is activated, that is, the network device cannot timely acquire the CSI report of the PUCCH SCell, thereby deferring the time point when the network device schedules the terminal device and reducing the system performance.

Therefore, a wireless communication method is needed in the art to enable the network device to acquire the CSI report of the PUCCH SCell in time, so as to improve the system performance.

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 the present embodiments are illustrated by way of example only with respect to communication system 100, but the present embodiments 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.

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 in the embodiment of the present application.

It should be understood that devices with communication functions in the network/system in 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.

It should also be understood that, in the embodiments of the present application, reference to "corresponding" may mean that there is a direct correspondence or an indirect correspondence between the two, or may mean that there is an association between the two, or may be a relationship between an instruction and an indicated, configured, or the like. It should also be understood that "predefined" or "predefined rules" mentioned in the embodiments of the present application may be implemented by pre-storing corresponding codes, tables or other manners that may be used to indicate relevant information in devices (e.g., including terminal devices and network devices), and the present application is not limited to a specific implementation thereof. Such as predefined may refer to what is defined in the protocol. It should also be understood that, in the embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied in future communication systems, which are not limited in this application.

In the present application, a terminal device may be configured with a primary physical uplink control channel (Physical Uplink Control Channel, PUCCH) Cell Group (CG) and a secondary PUCCH cell Group (2 nd PUCCH Group); wherein the primary PUCCH Cell group includes a special Cell (SPCell) and one or more Secondary cells (scells), and channel state information (Channel State Information, CSI) reports of serving cells in the primary PUCCH Cell group are all reported through the SPCell, and the serving cells may be activated scells; the secondary PUCCH cell group comprises a PUCCH SCell and one or more SCells, and the CSI reports of the service cells in the secondary PUCCH cell group are all reported through the PUCCH SCell.

As shown in fig. 2, when an SCell needs to be activated, assuming that the point of time when the terminal device receives an activation command for indicating to activate the SCell is a slot n, the terminal device may activate the SCell between the slot n+k and the activation delay requirement. For example, the terminal device may send the CSI report containing the l1_rsrp SCell to the network device on time slot n+k at the earliest.

It follows that if the SCell to be activated is one SCell in the primary PUCCH cell group, the terminal device may report the CSI report of the SCell before activating the SCell, e.g. reporting the CSI report of the SCell in time slot n+k, since the SPCell is always in an active state, even though the SCell has not yet been activated. However, if the SCell to be activated is a PUCCH SCell, the terminal device can send the SCI report of the PUCCH SCell through the activated PUCCH SCell only after receiving the activation command of the PUCCH SCell and the PUCCH SCell is activated, that is, the network device cannot timely acquire the CSI report of the PUCCH SCell, thereby deferring the time point when the network device schedules the terminal device and reducing the system performance.

Based on this, the embodiment of the application provides a wireless communication method, a terminal device and a network device, which can timely enable the network device to acquire the CSI report of the PUCCH SCell, thereby improving the system performance.

Fig. 3 shows a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, which method 200 may be performed interactively by a terminal device and a network device. The terminal device shown in fig. 2 may be a terminal device as shown in fig. 1, and the network device shown in fig. 2 may be an access network device as shown in fig. 1.

As shown in fig. 3, the method 200 may include some or all of the following:

s210, receiving a first command, wherein the first command is used for activating a Physical Uplink Control Channel (PUCCH) auxiliary cell (SCell);

s220, before activating the PUCCH SCell, transmitting a channel state information CSI report of the PUCCH SCell by using a special cell SPCell in the primary PUCCH cell group.

In this embodiment, after receiving the first command, the terminal device may send the CSI report of the PUCCH SCell by using the SPCell in the primary PUCCH cell group before activating the PUCCH SCell, which avoids that the terminal device sends the CSI report of the PUCCH SCell by using the PUCCH SCell after activating the PUCCH SCell, and is equivalent to enabling the network device to obtain the CSI report of the PUCCH SCell in advance, thereby improving, for example, system performance.

It should be noted that, the implementation manner of the first command is not limited in this application.

Illustratively, the first command may be a radio resource control (Radio Resource Control, RRC) for configuring the PUCCH SCell, in other words, the first command may be an RRC signaling for configuring the PUCCH SCell, at which time the PUCCH SCell may be activated by a first parameter in the first command, e.g. the first parameter may be a parameter in the RRC signaling for marking a secondary cell state; i.e. if the first parameter is marked as activated, it is equivalent to the first parameter indicating that the PUCCH SCell is activated. Alternatively, the PUCCH SCell need not be additionally activated by a Control Element (CE) indication of a medium access Control (Media Access Control, MAC). Of course, in other alternative embodiments, if the PUCCH SCell may be activated by the MAC CE indication, the first command may also be referred to as Activation or deactivation of the secondary cell MAC CE (SCell Activation/Deactivation MAC CE).

In some embodiments, the S220 may include:

transmitting a CSI report of the PUCCH SCell by using the SPCell on a first time domain resource unit before activating the PUCCH SCell;

wherein the first time domain resource unit is the earliest time domain resource unit available for activating the PUCCH SCell.

Optionally, the time domain resource unit where the first command is located is an nth time slot, the first time domain resource unit is an n+kth time slot, and the value of k is greater than 0.

In this embodiment, by using the SPCell to send the CSI report of the PUCCH SCell on the earliest time domain resource unit available for activating the PUCCH SCell before activating the PUCCH SCell, the network device can obtain the CSI report of the PUCCH SCell in advance to the greatest extent, thereby improving the system performance to the greatest extent.

Of course, in other alternative embodiments of the present application, the terminal device receives the activation command of the PUCCH SCell at the time slot n, and at this time, the terminal device may send the CSI report of the PUCCH SCell by using the SPCell at any time slot after the time slot n+k or the time slot n+k, but before the PUCCH SCell is activated. It is also to be understood that the time domain resource units referred to herein include, but are not limited to: frames, subframes, slots, symbols, etc.

In some embodiments, the S220 may include:

determining a second PUCCH resource on the SPCell based on the first PUCCH resource on the PUCCH SCell; the first PUCCH resource is associated with a reference signal measured on the PUCCH SCell;

and on the second PUCCH resource, sending the CSI report of the PUCCH SCell through the SPcell.

In one implementation, a first mapping relationship is obtained, the first mapping relationship including at least one third PUCCH resource and at least one fourth PUCCH resource in one-to-one correspondence with the at least one third PUCCH resource, the at least one third PUCCH resource including resources on the PUCCH SCell and associated with reference signals measured on a serving cell in the secondary PUCCH cell group, the at least one third PUCCH resource including the first PUCCH resource, the at least one fourth PUCCH resource including resources on the SPCell and not associated with reference signals measured on a serving cell in the primary PUCCH cell group; and determining a PUCCH resource corresponding to the first PUCCH resource in the at least one fourth PUCCH resource as the second PUCCH resource.

In other words, the reference signal measured on the serving cell in the secondary PUCCH cell group and at least one third PUCCH resource on the PUCCH SCell may be associated by the first mapping relation, and the at least one third PUCCH resource may be associated to at least one fourth PUCCH resource by the first mapping relation, and the at least one third PUCCH resource and the at least one fourth PUCCH resource may be in one-to-one correspondence. Wherein the at least one fourth PUCCH resource comprises a resource on the SPCell that is not associated with a reference signal measured on a serving cell in the primary PUCCH cell group. Alternatively, although the at least one fourth PUCCH resource is a PUCCH resource on the SPCell, the at least one fourth PUCCH resource is a resource reserved for CSI reporting of a serving cell in the secondary PUCCH cell group. Based on this, even if the terminal device transmits CSI reports of the PUCCH SCell through the SPCell on the at least one fourth PUCCH resource.

In this embodiment, since the at least one third PUCCH resource corresponds to the at least one fourth PUCCH resource one-to-one, equivalently, the network device may not only know that the CSI report sent through the SPCell on the at least one fourth PUCCH resource includes the CSI report of the PUCCH SCell, but also know that the reported CSI report is the CSI report of which reference signal of the PUCCH SCell, so that it can be ensured that understanding of the CSI report sent by the terminal device and the network device through the SPCell on the at least one fourth PUCCH resource remains consistent, and system performance is improved.

Of course, in other alternative embodiments, resources associated with only reference signals measured on the serving cells in the primary PUCCH cell group may also be included on the SPCell, which is not specifically limited in this application.

Fig. 4 is an example of an association relationship between reference signals and PUCCH resources measured on a serving cell in a cell group provided in an embodiment of the present application.

As shown in fig. 4, the reference signals measured on the serving cells in the secondary PUCCH cell group may be associated with at least one third PUCCH resource on the PUCCH SCell and at least one fourth PUCCH resource on the SPCell at the same time, and the at least one fourth PUCCH resource is not associated with the reference signals measured on the serving cells in the primary PUCCH cell group. Optionally, the at least one third PUCCH resource corresponds to the at least one fourth PUCCH resource one-to-one.

It should be noted that, the serving cell generally refers to an activated secondary cell, however, a serving cell in the secondary PUCCH cell group referred to in the present application may include a cell to be activated indicated by the first command, for example, if the first command is only used to indicate activation of the PUCCH SCell, the serving cell in the secondary PUCCH cell group includes the PUCCH SCell; if the first command is used to indicate to activate the PUCCH SCell and other cells in the secondary PUCCH cell group, the serving cell in the secondary PUCCH cell group may include the PUCCH SCell to be activated and other cells to be activated in the secondary PUCCH cell group. Or, when the CSI report of the PUCCH SCell is sent through the SPCell, the present application may report the CSI report by using the cell to be activated indicated by the first command as a serving cell in the secondary PUCCH cell group.

Optionally, determining a PUCCH resource having the same index value as the first PUCCH resource in the at least one fourth PUCCH resource as the second PUCCH resource.

Optionally, the first mapping relationship is predefined, or the first mapping relationship is configured through RRC signaling.

In another implementation, a second mapping relationship is obtained, the second mapping relationship including at least one third PUCCH resource and at least one fifth PUCCH resource in one-to-one correspondence with the at least one third PUCCH resource, the at least one third PUCCH resource including a resource on the PUCCH SCell and associated with a reference signal measured on a serving cell in the secondary PUCCH cell group, the at least one third PUCCH resource including the first PUCCH resource, the at least one fifth PUCCH resource including a resource on the SPCell and associated with a reference signal measured on a serving cell in the primary PUCCH cell group; and determining a PUCCH resource corresponding to the first PUCCH resource in the at least one fifth PUCCH resource as the second PUCCH resource.

In other words, the reference signal measured on the serving cell in the secondary PUCCH cell group and at least one third PUCCH resource on the PUCCH SCell may be associated by the first mapping relation, and the at least one third PUCCH resource may be associated to at least one fifth PUCCH resource by the first mapping relation, and the at least one third PUCCH resource and the at least one fourth PUCCH resource may be in one-to-one correspondence. Wherein the at least one fifth PUCCH resource comprises a resource on the SPCell that is associated with a reference signal measured on a serving cell in the primary PUCCH cell group. Alternatively, although the at least one fifth PUCCH resource is a PUCCH resource on the SPCell, the at least one fifth PUCCH resource may also be used to transmit CSI reports of serving cells in the secondary PUCCH cell group, that is, the at least one fifth PUCCH resource may be a shared resource of CSI reports of serving cells in the primary PUCCH cell group and CSI reports of serving cells in the secondary PUCCH cell group. Based on this, even though a terminal device may send CSI reports of the PUCCH SCell over the SPCell on the at least one fifth PUCCH resource.

Fig. 5 is another example of an association relationship between a reference signal measured on a serving cell and PUCCH resources in a cell group provided in an embodiment of the present application.

As shown in fig. 5, the reference signals measured on the serving cells in the secondary PUCCH cell group may be associated with at least one third PUCCH resource on the PUCCH SCell, and the reference signals measured on the serving cells in the primary PUCCH cell group may be associated with at least one fifth PUCCH resource on the SPCell. Optionally, the at least one fifth PUCCH resource corresponds to the at least one fourth PUCCH resource one-to-one.

Optionally, determining a PUCCH resource having the same index value as the first PUCCH resource in the at least one fifth PUCCH resource as the second PUCCH resource.

Optionally, the second mapping relationship is predefined, or the second mapping relationship is configured through RRC signaling.

In some embodiments, the S220 may include:

and if the CSI report of the serving cell in the main PUCCH cell group to be transmitted exists on the second PUCCH resource, preferentially transmitting the CSI report of the PUCCH SCell.

Of course, in other alternative embodiments, if there is a CSI report of the serving cell in the primary PUCCH cell group to be transmitted on the second PUCCH resource, the CSI report of the serving cell in the primary PUCCH cell group may also be preferentially transmitted, which is not limited in detail in this application.

Optionally, the CSI report of the PUCCH SCell includes a first identifier, where the first identifier is used to identify that the CSI report reported on the second PUCCH resource is a CSI report of a serving cell in the primary PUCCH cell group, or the CSI report that is reported on the second PUCCH resource includes a CSI report of the PUCCH SCell.

In this embodiment, since the at least one third PUCCH resource corresponds to the at least one fifth PUCCH resource in a one-to-one manner, the network device may not only know that the CSI report sent through the SPCell on the at least one fifth PUCCH resource includes the CSI report of the PUCCH SCell, but also know that the reported CSI report is the CSI report of which reference signal of the PUCCH SCell, so that it can be ensured that understanding of the CSI report sent through the SPCell on the at least one fifth PUCCH resource by the terminal device and the network device remains consistent, and system performance is improved.

In some embodiments, the CSI report of the PUCCH SCell is a semi-persistently scheduled CSI report or a periodic CSI report.

In some embodiments, the CSI report of the PUCCH SCell includes a layer1 reference signal received power (layer1 Reference Signal Receiving Power, l1_rsrp) value of the first reference signal.

Optionally, layer1 is used to provide a transmission and reception radio link between the base station and the terminal device. For example, the Physical Layer (Physical Layer).

Of course, the CSI report of the PUCCH SCell includes the l1_rsrp value only as an example of the present application and should not be construed as limiting the present application. For example, in other alternative embodiments, the CSI report of the PUCCH SCell may include an l1_rsrp value and/or an l3_rsrp value. For another example, the CSI report of the PUCCH SCell may include an RSRP value and/or a reference signal received quality (Reference Signal Receiving Quality, RSRQ) value. Wherein layer 3 is used to communicate control messages. For example, layer 3 includes, but is not limited to, the internet protocol (Internet Protocol, IP) layer and the radio resource control (Radio Resource Control, RRC) layer, as well as the non-access stratum (NAS). For example, the RSRP value measured by the above layer 3 may be understood as an RSRP value obtained by performing the measurement for the RRC layer.

In some embodiments, the first reference signal comprises at least one of:

synchronization signals and/or physical broadcast channel blocks SSB, channel state information reference signals CSI RS.
