Description

Reference signal processing method, network device and terminal

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method, a network device, and a terminal for processing a reference signal.

Background

Fifth generation (5)^thGeneration, abbreviated as 5G) mobile communication systems support switching transmission of Sounding Reference Signals (SRS) between Component Carriers (CC). According to different SRS transmission periods, periodic SRS transmission, semi-continuous SRS transmission and aperiodic triggering SRS are supported.

When the SRS switches transmission among the component carriers, the SRS is transmitted according to the following rules:

(1) if the SRS and the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH) carrying the Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK), the Scheduling Request (SR), the Rank Indication (RI), the Channel State Information Indication (CRI) or the Physical Random Access Channel (PRACH) appear on the same symbol, the SRS and the Physical Uplink Control Channel are discarded.

(2) If the SRS and the PUSCH carrying aperiodic Channel State Information (CSI) appear on the same symbol, the SRS is discarded.

(3) If the SRS and the PUCCH/PUSCH carrying periodic CSI including Channel Quality Indication (CQI)/Precoding Matrix Indication (PMI) appear on the same symbol, the PUCCH/PUSCH is discarded. Because the 5G system supports a wider Bandwidth, in order to reduce the power consumption requirement of a terminal (User Equipment, abbreviated as UE), the UE is supported to transmit SRS in a partial Bandwidth (BWP), and the BWP is smaller than the Bandwidth of the CC. The UE may transmit SRS in different BWPs according to the network side configuration, but only one active BWP at a time.

The prior art only supports the SRS to be transmitted in the active BWP, and when the UE switches to another BWP, the channel quality of the corresponding BWP cannot be obtained in time, which may cause frequent switching between BWPs and decrease system efficiency.

It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments.

It should be noted that the communication device in the embodiment of the present invention may be the terminal 11 or may be the network device 12, and the specific functions of the communication device will be described in detail through the following embodiments.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for processing a reference signal according to an embodiment of the present invention, where the method for processing the reference signal is applied to a network device, and includes:

step 21: transmitting configuration information to a terminal on a first transmission resource, wherein the configuration information comprises transmitting a reference signal for Channel State Information (CSI) measurement or beam management on at least one second transmission resource, and the reference signal is triggered periodically or semi-persistently or non-periodically;

in some embodiments of the present invention, the first transmission resource is active BWP or inactive BWP, and the second transmission resource is inactive BWP, and since a reference signal for CSI measurement or beam management is configured to be transmitted on the inactive BWP, when the terminal switches from the active BWP to the inactive BWP, the channel quality of the inactive BWP can be obtained in time, thereby avoiding the delay caused by BWP switching and improving the system efficiency. The method of the embodiment of the invention is also suitable for an uplink and downlink BWP asymmetric scene in a Time Division Duplex (TDD) system, such as: the downstream BWP width is the sum of the widths of a plurality of upstream BPWs, and the CSI measurement reference signal BWP switching can obtain broadband channel information.

In some other embodiments of the present invention, the first transmission resource is a New Radio (NR) carrier, and the second transmission resource is a Long Term Evolution (LTE) carrier, that is, in an NR system, a reference signal for CSI measurement or beam management may be sent to a terminal configured on the LTE carrier, and when the terminal is switched from the NR carrier to the LTE carrier, the channel quality of the LTE carrier may be obtained in time, so as to avoid a time delay caused by carrier switching, and improve system efficiency.

In the embodiment of the invention, the reference signal for CSI measurement or beam management is sent to the terminal on at least one second transmission resource configured on the first transmission resource, so that when the terminal is switched among different transmission resources, the channel quality of the corresponding transmission resource can be obtained in time, the time delay caused by the switching of the transmission resource is avoided, and the system efficiency is improved.

In this embodiment of the present invention, when the first transmission resource is an inactive BWP and the second transmission resource is an inactive BWP, the first transmission resource and the second transmission resource are the same or different transmission resources. The first transmission resource and the second transmission resource are the same transmission resource, which means that the second transmission resource is the first transmission resource, that is, the configuration information, which is configured by the network device to the terminal and used for sending the reference signal for CSI measurement or beam management on a certain inactive BWP, is configured on the inactive BWP. The first transmission resource and the second transmission resource are different transmission resources, which means that the second transmission resource is not the first transmission resource, for example, configuration information that the network device sends a reference signal for CSI measurement or beam management on the inactive BWP is configured on the active BWP. For another example, the network device transmits configuration information of a reference signal for CSI measurement or beam management on an inactive BWP configured to the terminal on another inactive BWP.

In this embodiment of the present invention, the reference signal for CSI measurement or beam management is a reference signal for uplink CSI measurement or beam management or a reference signal for downlink CSI measurement or beam management.

In one case, the reference signal includes an SRS when the reference signal is a reference signal for uplink CSI measurement or beam management. Of course, in other embodiments of the present invention, it is not excluded that the reference signal is other types of reference signals for uplink CSI measurement or beam management.

In another case, when the reference Signal is a reference Signal for downlink CSI measurement or beam management, the reference Signal includes at least one of a non-zero power channel state information reference Signal (NZP-CSI-RS), a zero power channel state information reference Signal (ZP-CSI-RS), or a synchronization information Block (SSB). Of course, in some other embodiments of the present invention, it is not excluded that the reference signal is other type of reference signal for downlink CSI measurement or beam management.

In this embodiment of the present invention, the configuration information may further include: at least one of a guard interval of the reference signal transmission and transmission offset related information of the reference signal.

The guard interval for transmitting the reference signal refers to a transmission interval of adjacent reference signals when the reference signal is transmitted on the transmission resource. The guard interval for reference signal transmission is a value greater than or equal to 0, and is associated with different subcarrier spacing configurations. Preferably, the larger the subcarrier spacing is, the larger the guard interval of the reference signal transmission is, and the smaller the subcarrier spacing is, the smaller the guard interval of the reference signal transmission is, for example, as shown in table 1.

Table 1: subcarrier spacing and guard spacing

Subcarrier spacing (kHz)	Symbol length (us)	Guard interval (symbol)
			15	71.43	0
30	35.71	1
			60	17.86	1
120	8.93	2
			240	4.64	3
480	2.32	7

The information related to the transmission offset of the reference signal refers to a time between when the network device configures the reference signal for CSI measurement or beam management on the at least one second transmission resource on the first transmission resource and starts to transmit the configuration information, or a time between when the terminal receives the configuration information configured by the network device and starts to transmit the reference signal for CSI measurement or beam management on the at least one second transmission resource and applies the configuration information.

In this embodiment of the present invention, the step of sending the configuration information to the terminal on the first transmission resource includes:

sending a resource or a resource set of the reference signal corresponding to each transmission resource to the terminal, where the transmission resource includes the first transmission resource and the second transmission resource; and

indicating, to the terminal, the second transmission resource used for transmitting the reference signal, and a resource or a resource set of the reference signal used by the second transmission resource for transmitting the reference signal, where the resource or the resource set of the reference signal used by the second transmission resource for transmitting the reference signal is at least part of the resource or the resource set of the reference signal corresponding to the second transmission resource.

That is, the network device configures a resource or a resource set of the reference signal corresponding to each transmission resource to the terminal. For example, the content of the configuration may be as follows:

activating BWP 1-resource A, resource B, and resource C;

inactive BWP2 — resource C and resource D;

inactive BWP3 — resource E.

It can be seen that the resources or resource sets of the reference signals corresponding to different transmission resources are different.

When the network device indicates the second transmission resource for transmitting the reference signal to the terminal, the network device may use an identifier indication of the second transmission resource, or use a mode indication of a starting frequency domain position + a bandwidth of the second transmission resource.

In this embodiment of the present invention, the reference signal may be triggered periodically or semi-persistently or non-periodically, and for different types of reference signals, different manners of "sending a resource or a resource set of the reference signal corresponding to each transmission resource to the terminal, and indicating, to the terminal, the second transmission resource used for sending the reference signal, and sending, by the second transmission resource, the resource or the resource set of the reference signal used for sending the reference signal" are different, which is described in the following by way of example.

In this embodiment of the present invention, when the reference signal for CSI measurement or beam management is a periodic reference signal, the step of sending, to the terminal, a resource or a resource set of the reference signal corresponding to each transmission resource, and indicating, to the terminal, the second transmission resource used for sending the reference signal, and the resource or the resource set of the reference signal used by the second transmission resource for sending the reference signal, may include:

configuring a Resource or a Resource set of the reference signal corresponding to each transmission Resource to the terminal through Radio Resource Control (RRC) signaling, indicating, to the terminal through RRC signaling, the second transmission Resource used for sending the reference signal, and sending, by the second transmission Resource, a Resource or a Resource set of the reference signal used by the reference signal, where the Resource or the Resource set of the reference signal used by the reference signal sent by the second transmission Resource is at least part of the Resource or the Resource set of the reference signal corresponding to the second transmission Resource.

In this embodiment of the present invention, when the reference signal for CSI measurement or beam management is a semi-persistent reference signal, the step of sending, to the terminal, a resource or a resource set of the reference signal corresponding to each transmission resource, and indicating, to the terminal, the second transmission resource used for sending the reference signal, and the resource or the resource set of the reference signal used for sending the reference signal by the second transmission resource, may include:

sending, by an RRC signaling, a resource or a resource set of the reference signal corresponding to each transmission resource to the terminal, indicating, by a media access control layer control element (MAC CE), to the terminal, the second transmission resource used for sending the reference signal, and a resource or a resource set of the reference signal used by the second transmission resource to send the reference signal, where the resource or the resource set of the reference signal used by the second transmission resource is at least part of the resource or the resource set of the reference signal corresponding to the second transmission resource.

In this embodiment of the present invention, when the reference signal for CSI measurement or beam management is a semi-persistent SRS, the step of sending the resource or the resource set of the reference signal corresponding to each transmission resource to the terminal may include: and configuring the resources or resource sets of the reference signals corresponding to the transmission resources and the quasi-co-location information of the resources of each reference signal to the terminal through the MAC CE. The quasi-co-location information provides spatial transmission filtering reference parameters of the reference signal, and can be a CSI-RS identifier, an SSB identifier or a periodic SRS identifier.

In this embodiment of the present invention, when the reference signal for CSI measurement or beam management is an aperiodic-triggered reference signal, the step of sending, to the terminal, a resource or a resource set of the reference signal corresponding to each transmission resource, and indicating, to the terminal, the second transmission resource used for sending the reference signal, and a resource or a resource set of the reference signal used by the second transmission resource for sending the reference signal, may include:

sending a resource or a resource set of the reference signal corresponding to each transmission resource to the terminal through an RRC signaling, indicating, to the terminal, a second transmission resource used for sending the reference signal through Downlink Control Information (DCI), and sending, by the second transmission resource, a resource or a resource set of the reference signal used by the reference signal, where the resource or the resource set of the reference signal used by the reference signal sent by the second transmission resource is at least part of the resource or the resource set of the reference signal corresponding to the second transmission resource; or

Sending the resource or resource set of the reference signal corresponding to each transmission resource to the terminal through RRC signaling, instructing the terminal to select at least part of the resource or resource set of the reference signal from the configured resource or resource set of the reference signal to activate through a media access control layer control element MAC CE, and instructing the terminal to send the second transmission resource used for sending the reference signal and the resource or resource set of the reference signal adopted by the second transmission resource, where the resource or resource set of the reference signal adopted by the second transmission resource is at least part of the activated resource or resource set of the reference signal.

In this embodiment of the present invention, the configuration information may further include: the reference signal sent on the second transmission resource and signals sent on other transmission resources are sent in a time division or frequency division mode;

the time division transmission mode can reduce the transmitting power and avoid the power boosting problem.

And the frequency division transmission mode can realize rapid bandwidth measurement, and further improve the switching efficiency of transmission resources.

When the reference signal is an SRS, the reference signal sent on the second transmission resource is an SRS, and the signals sent on the other transmission resources include a PUSCH, a PUCCH, a PRACH, or an SRS;

when the reference signal is at least one of NZP-CSI-RS, ZP-CSI-RS or SSB, the reference signal sent on the second transmission resource is NZP-CSI-RS, ZP-CSI-RS or SSB, and the signals sent on the other transmission resources include a Physical Downlink Shared Channel (PDSCH), a Physical Downlink Control Channel (PDCCH), SSB, NZP-CSI-RS or ZP-CSI-RS.

In this embodiment of the present invention, when the reference signal is a reference signal for uplink CSI measurement or beam management, at least one of the following steps is further included after the step of sending configuration information to the terminal on the first transmission resource:

if the reference signal sent on the second transmission resource and the resource occupied by the guard interval sent by the reference signal and the PUCCH carrying HARQ-ACK, SR, RI, or CRI sent on the other transmission resource, or the PUSCH carrying HARQ-ACK, SR, RI, or CRI, or the PRACH simultaneously appear on at least one symbol, discarding the received reference signal sent by the terminal on the second transmission resource;

if the reference signal sent on the second transmission resource and the resource occupied by the guard interval sent by the reference signal appear on at least one symbol simultaneously with the PUSCH carrying the aperiodic CSI sent on the other transmission resources, discarding the received reference signal sent by the terminal on the second transmission resource;

if the reference signal sent on the second transmission resource and the resource occupied by the guard interval sent by the reference signal and the resource occupied by the reference signal sent on the second transmission resource and the PUCCH carrying the periodic CSI containing CQI or PMI sent on the other transmission resource or the PUSCH carrying the periodic CSI containing CQI or PMI appear on at least one symbol at the same time, discarding the received PUCCH carrying the periodic CSI containing CQI or PMI or the PUSCH carrying the periodic CSI containing CQI or PMI;

if the reference signal sent on the second transmission resource and the resource occupied by the guard interval sent by the reference signal appear on at least one symbol simultaneously with the PUSCH carrying no CSI sent on the other transmission resources, discarding the received reference signal sent by the terminal on the second transmission resource;

if the resources occupied by the reference signal sent by the second transmission resource and the guard interval sent by the reference signal and the resources occupied by the periodic reference signal sent by the other transmission resources and the resources occupied by the guard interval sent by the periodic reference signal sent by the other transmission resources simultaneously appear on at least one symbol, discarding the received periodic reference signal sent by the terminal on the other transmission resources;

Based on the above, when the reference signal sent by the second transmission resource conflicts with the resource occupied by the signal sent by the other transmission resource, a better conflict solution mechanism can be provided to ensure the normal operation of the system.

The above-described collision resolution mechanism is applicable to the case where the total power of the second transmission resource and the other transmission resources is lower than or equal to or greater than the maximum transmission power of the terminal.

When the total power of the second transmission resource and the other transmission resources is lower than or equal to the maximum transmission power of the terminal, and the reference signal is a reference signal for uplink CSI measurement or beam management, the configuration information may further include: and when the total power of the terminal on the second transmission resource and the other transmission resources is lower than or equal to the maximum transmission power of the terminal, the reference signal sent on the second transmission resource and the signals sent on the other transmission resources are sent in a frequency division manner.

In this embodiment of the present invention, when the network device indicates the inactive BWP for sending the SRS to the terminal, the network device may use an identifier indication of the inactive BWP, or use a mode indication of a starting frequency domain position + bandwidth of the inactive BWP.

In this embodiment of the present invention, a network device configures to send an SRS sent on an inactive BWP and a signal sent on another transmission resource by using a time-division or frequency-division transmission manner, where the other transmission resource may be an active BWP or an inactive BWP, when the other transmission resource is the active BWP, the signal sent on the active BWP includes a PUSCH, a PUCCH, a PRACH, or an SRS, and when the other transmission resource is the inactive BWP, the signal transmitted on the other transmission resource is the SRS.

In some embodiments, the network device configures the terminal with a periodic SRS or a semi-persistent SRS or a non-periodic triggered SRS on the active BWP, and the SRS transmitted on the inactive BWP is transmitted in a time division manner with the PUSCH, PUCCH, PRACH, or SRS transmitted on the active BWP.

In some embodiments, the network device configures, on at least one inactive BWP, the terminal to transmit a periodic SRS or a semi-persistent SRS on the current inactive BWP or a non-periodic triggered SRS, where the SRS transmitted on the inactive BWP is transmitted in a time division manner with the PUSCH, PUCCH, PRACH, or SRS transmitted on the active BWP.

In some embodiments, the network device configures, on at least one inactive BWP, the terminal to transmit a periodic SRS or a semi-persistent SRS on the current inactive BWP or a non-periodic triggered SRS, where the SRS transmitted on the inactive BWP is transmitted in a frequency division manner with the PUSCH, PUCCH, PRACH, or SRS transmitted on the active BWP.

In this embodiment of the present invention, after the step of configuring the SRS that is transmitted on the inactive BWP and the signal that is transmitted on the other transmission resource by using the frequency division method, the network device further includes at least one of the following steps:

if the SRS sent by the inactive BWP and the resource occupied by the SRS sent guard interval, and a PUCCH carrying HARQ-ACK, SR, RI or CRI sent by the active BWP, or a PUSCH carrying HARQ-ACK, SR, RI or CRI, or a PRACH simultaneously appear on at least one symbol, discarding the received SRS sent by the terminal on the inactive BWP;

if the SRS sent by the inactive BWP and the resource occupied by the guard interval sent by the SRS occur on at least one symbol simultaneously with the PUSCH which is sent by the active BWP and carries the aperiodic CSI, discarding the received SRS sent by the terminal on the inactive BWP;

if the resources occupied by the SRS sent by the inactive BWP and the guard interval sent by the SRS are the same as the PUCCH which is sent by the active BWP and carries the periodic CSI containing the CQI or PMI or the PUSCH which carries the periodic CSI containing the CQI or PMI and appears on at least one symbol, discarding the received PUCCH which carries the periodic CSI containing the CQI or PMI or the PUSCH which carries the periodic CSI containing the CQI or PMI;

Based on the above, when the SRS transmitted on the inactive BWP conflicts with the resource occupied by the signal transmitted on the active BWP, a better conflict resolution mechanism is proposed to ensure the normal operation of the system.

The above-described collision resolution mechanism is applicable to the case where the total power of the inactive BWP and the active BWP is lower than or equal to or greater than the maximum transmit power of the terminal.

When the total power of the inactive BWP and the active BWP is lower than or equal to the maximum transmission power of the terminal, the network device may configure the terminal to transmit the SRS transmitted on the inactive BWP and the signal transmitted on the active BWP in a frequency division manner.
