Description

Method and device for sending and receiving semi-persistent channel state information report

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for sending and receiving a semi-persistent channel status information report.

Background

With the development of mobile communication technology, the desire for 5G (5Generation, fifth Generation) mobile communication systems has arisen. To support greater system and user throughput, the 5G system supports partitioning in the frequency domain, enabling user equipment to receive and transmit signals on different frequency domain transmission resources.

For example, a 5G system supports a maximum 400MHz system bandwidth, which is much larger than the maximum 20MHz system bandwidth of LTE, thus supporting greater system and user throughput. Meanwhile, the 5G system also supports dynamic flexible bandwidth allocation, and may divide the system bandwidth into a plurality of bandwidth parts bwp (band Width part) to support narrowband end users or end users in an energy-saving mode, so that they only need to work on part of the system bandwidth.

As another example, 2 or more component carriers cc (component carrier) may be aggregated together to support a larger transmission bandwidth (up to 100MHz) using carrier aggregation ca (carrier aggregation) technology. Each component carrier CC corresponds to an independent Cell. A cell operating on the primary frequency band is called a primary cell pcell (primarycell), and a cell operating on the secondary frequency band is called a secondary cell scell (secondary cell). In the wireless communication process, different secondary cells scells may be activated (or may be referred to as turned on) as needed to provide additional wireless resources to meet communication requirements.

In a communication system where multiple frequency domain transmission resources exist, different frequency domain transmission resources may be activated as needed for wireless communication. Therefore, there is a need for a method for transmitting and receiving a semi-persistent csi report, which enables a user equipment to continuously and uninterruptedly transmit a semi-persistent csi report based on a PUSCH when a frequency domain transmission resource is changed.

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 some, not all, embodiments of the present invention. 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.

The technical solution of the present invention can be applied to various communication systems having a plurality of similar frequency domain transmission resources or spatial domain positions, such as a 5G (5-Generation, fifth Generation) NR (New Radio, New air interface) mobile communication system, an LTE (E-UTRA connect to 5GC) connected to a 5G core network 5GC, and the like.

User equipment (ue) (also referred to as mobile terminal mt), (mobile terminal), mobile user equipment (ue), and the like, may communicate with one or more core networks via a Radio Access Network (RAN, Radio Access Network, for example), and the user equipment may be mobile terminals, such as mobile phones (or "cellular" phones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-embedded, or vehicle-mounted mobile devices, which exchange languages and/or data with the Radio Access Network.

The Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, or an evolved node b (eNB or e-NodeB) and a 5G Base Station (gNB) in LTE.

In order to more flexibly perform the receiving and transmitting of signals, in the 5G system, the frequency domain may be divided. For example, the system bandwidth may be divided into a plurality of portions, forming a plurality of bandwidth portions bwp (band Width part); a frequency band, a carrier, or a component carrier (component carrier) of the system may be divided to form a plurality of frequency domain transmission resources, and a plurality of secondary cells scells (secondary cells) may be formed.

In a communication system, a network device may configure frequency domain transmission resources of a serving cell for a user equipment. For example, at least one Downlink bandwidth part DL BWP (Downlink bandwidth part) for Downlink (Downlink Link) reception may be configured for the ue through a higher layer signaling — radio Resource control rrc (radio Resource control) message, and if multiple Downlink bandwidth parts DL BWPs are configured, a Downlink bandwidth part set (DL BWP set) may be formed. It may be provided that the network device may configure a maximum of four downlink bandwidth parts, DL BWPs, for the user equipment. For another example, at least one Uplink bandwidth Part UL BWP (Uplink bandwidth Part) for Uplink (UL Link) transmission may be configured for the user equipment through a higher layer signaling, i.e., a radio resource control RRC message, and if multiple Uplink bandwidth parts UL BWPs are configured, an Uplink bandwidth Part set (UL BWP set) may be formed. It may be provided that the network device may configure a maximum of four uplink bandwidth parts, UL BWPs, for the user equipment.

For a communication system divided with multiple frequency domain transmission resources (taking the frequency domain transmission resources as the bandwidth part BWP as an example), the network device may indicate the activated downlink bandwidth part DL BWP by sending downlink Control information DCI (downlink Control information) on a physical downlink Control channel pdcch (physical downlink Control channel) according to needs, for example, may activate the downlink bandwidth part DL BWP by using a bandwidth part indication (bandwidth part indicator) field in the downlink Control information DCI. Correspondingly, the ue receives information on a physical Downlink control channel PDCCH and a physical Downlink Shared channel pdsch (physical Downlink Shared channel) according to a Subcarrier spacing (Subcarrier spacing) and a length of a cyclic prefix cp (cyclic prefix) of a numerical parameter (numerology) corresponding to the Downlink bandwidth part DL BWP indicated by the Downlink control information DCI.

In addition, the network device may also indicate an activated uplink bandwidth part UL BWP in a bandwidth part indication (bandwidth part indicator) field in the downlink DCI, as needed. Correspondingly, the ue transmits information on a physical Uplink Control channel pucch (physical Uplink Control channel) and a physical Uplink shared channel pusch (physical Uplink shared channel) according to the subcarrier spacing and CP length configured by the UL BWP of the Uplink bandwidth part where the ue is located.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Example 1

Referring to fig. 1, an embodiment of the present invention provides a method for sending a semi-persistent CSI report, which is applied to a user equipment and is used for sending the semi-persistent CSI report based on a PUSCH resource configuration of a physical uplink shared channel. The method may specifically comprise:

step 101: and receiving a first indication on the first downlink frequency domain transmission resource, wherein the first indication is used for activating the first uplink frequency domain transmission resource.

It should be noted that, the user equipment executes the first indication received in step 301, and can activate the first uplink frequency domain transmission resource. For example, when the frequency domain transmission resource is a bandwidth portion BWP, the user equipment may switch the uplink bandwidth portion UL BWP from the second uplink bandwidth portion UL BWP (which may be denoted as UL BWPi) to the first uplink bandwidth portion UL BWP (which may be denoted as UL BWPj) by receiving the first indication on the first downlink bandwidth portion. It can be appreciated that the user equipment will stop sending information to the network device on the second upstream bandwidth part UL BWP after switching to the first upstream bandwidth part UL BWP.

For another example, when the frequency domain transmission resource is a secondary cell SCell, the user equipment may activate a first uplink secondary cell UL SCell (which may be denoted as UL SCellj) by receiving the first indication. It can be understood that after activating (also referred to as turning on) the first uplink secondary cell UL SCellj, the ue may send information to the network device on the first uplink secondary cell UL SCellj.

Optionally, when the uplink frequency domain transmission resource is an uplink bandwidth portion UL BWP, the ue may receive uplink control information UCI including the first indication, and activate the first uplink frequency domain transmission resource (specifically, the first uplink bandwidth portion).

Optionally, when the uplink frequency domain transmission resource is an uplink secondary cell UL SCell, the ue may receive a Medium Access Control element MAC CE (Medium Access Control-Control element) including the first indication, and activate the first uplink frequency domain transmission resource (specifically, the first uplink secondary cell).

Step 103: when a preset condition is met, sending a CSI report on a first uplink frequency domain transmission resource based on a Physical Uplink Shared Channel (PUSCH) resource configuration corresponding to the first uplink frequency domain transmission resource and a first signal state information (CSI) report configuration corresponding to the first downlink frequency domain transmission resource; the first CSI report configuration comprises a periodic characteristic of a CSI report, and the periodic characteristic is semi-persistent.

The preset conditions include: determining that a first CSI reporting configuration exists, receiving a first activation indication on a first downlink frequency domain transmission resource, and determining that the first uplink frequency domain transmission resource is in an activated state. The first activation indication is used for activating sending of the CSI report according to a first CSI report configuration corresponding to a first downlink frequency domain transmission resource, or activating sending of the CSI report according to a CSI report configuration corresponding to at least one downlink frequency domain transmission resource.

It should be noted that the CSI report configuration corresponding to the downlink frequency domain transmission resource may be configured by the ue by receiving first configuration information carrying CSI report configuration (Reporting setting). The first configuration information may be received in a radio resource control RRC message. In specific implementation, the first configuration information may include a CSI report configuration corresponding to at least one downlink frequency domain transmission resource, or may further include CSI report configurations corresponding to all downlink frequency domain transmission resources. Correspondingly, the ue may configure a CSI report configuration for each downlink frequency domain transmission resource independently (which is equivalent to only configuring one corresponding downlink frequency domain transmission resource in one CSI report configuration), or configure a plurality of corresponding downlink frequency domain transmission resources, for example, all downlink frequency domain transmission resources in one CSI report configuration.

It should be further noted that the PUSCH resource configuration of the physical uplink shared channel corresponding to the uplink frequency domain transmission resource (including the first uplink frequency domain transmission resource, for example, the first uplink bandwidth part UL BWP) may be configured by the user equipment by receiving the second configuration information carrying the PUSCH resource configuration. The uplink frequency domain transmission resource in the second configuration information may correspond to a plurality of candidate PUSCH resource configurations, and the network device may send the second configuration information in a radio resource control RRC message manner, and use DCI to indicate a PUSCH resource configuration used to select the uplink frequency domain transmission resource. The second type of configuration information may include PUSCH resource configurations corresponding to at least one uplink frequency domain transmission resource, and may also further include PUSCH resource configurations corresponding to all candidate uplink frequency domain transmission resources. It can be understood that the PUSCH resource configuration is used to determine resources occupied by a PUSCH used for sending a CSI report on an uplink frequency domain transmission resource corresponding to the PUSCH resource configuration.

Optionally, the second configuration information may indicate one PUSCH resource parameter. The PUSCH resource parameters may include at least one of a time domain position and a frequency domain transmission resource, such as a slot offset, an OFDM symbol position, a frequency domain subcarrier position, and the like, and correspond to PUSCH resources used for transmitting SP-CSI reports on all UL BWPs, that is, the same PUSCH resource parameters may be used on different uplink frequency domain transmission resources (e.g., UL BWPs).

For example, the PUSCH resource configuration includes a plurality of PUSCH resource parameters, and is defined by RRC configuration or protocol. When sending of the SP CSI report is activated, the DCI carrying the first activation indication selects and indicates one PUSCH resource determined by the PUSCH resource parameter to be used for sending the SP CSI report. This PUSCH resource parameter is not changed when UL BWP handover occurs.

Optionally, the second configuration information may indicate one PUSCH resource parameter for each PUSCH resource used for transmitting the SP CSI report on the UL BWP. The PUSCH resource parameters may include at least one of a time domain position and a frequency domain transmission resource, such as a slot offset, an OFDM symbol position, a frequency domain subcarrier position, and the like. The same or different PUSCH resource parameters may be used on different uplink frequency domain transmission resources (e.g. uplink bandwidth part, UL BWP).

For example, the PUSCH resource configuration includes a plurality of PUSCH resource parameters, which are specified by RRC configuration or protocol, and one of the PUSCH resource parameters is indicated by DCI selection. Further:

(1) when the sending of the SP CSI report is activated, one of the PUSCH resource parameters may be selected and indicated in the DCI of the first activation indication, and the PUSCH resource on the currently activated UL BWP may be determined according to the PUSCH resource parameter, and then the SP CSI report may be sent according to the determined PUSCH resource. When UL BWP switching occurs, one PUSCH resource parameter is indicated and indicated in the first indicated DCI, a PUSCH resource on the UL BWP to be activated is determined according to the PUSCH resource parameter, and then an SP CSI report is sent according to the determined PUSCH resource.

(2) Multiple sets of PUSCH resource parameters may be determined, where each set of PUSCH resource parameters corresponds to PUSCH resources on a respective UL BWP for transmitting SP CSI reports. When SP CSI report is activated, a group of PUSCH resource parameters are selected and indicated from the DCI of the first activation indication, and the PUSCH resource used for sending the SP CSI report on the currently activated UL BWP is determined according to the PUSCH resource parameters corresponding to the currently activated UL BWP. When the switching of the bandwidth part BWP occurs, the PUSCH resource parameters corresponding to the UL BWP to be activated in the set of PUSCH resource parameters may be directly used without a new selection indication to determine the PUSCH resources on the UL BWP to be activated for sending the SP CSI report.

In specific implementation, the PUSCH resource parameter may be configured by using an RRC configuration table. The PUSCH resource of the uplink frequency domain transmission resource may determine a time domain position by a row number in the DCI indication configuration table, may include information such as a PUSCH transmission time and a DCI scheduling time uplink slot offset K2 defined by each row in the DCI indication configuration table, a symbol start within the slot, a length indication SLIV, and the like, and indicates an occupied frequency domain resource (frequency domain transmission resource).

For a semi-persistent CSI report (which may be denoted as an SP CSI report), after the user equipment receives the first indication and activates the first uplink frequency domain transmission resource, if the network device does not configure a PUSCH resource for transmitting the SP CSI report on the first uplink frequency domain transmission resource (e.g., UL BWPj) for the user equipment, the user equipment does not transmit a PUSCH-based SPCSI report after the first uplink frequency domain transmission resource is activated. Correspondingly, the network device does not receive PUSCH-based SPCSI reports.

For a semi-persistent CSI report (which may be denoted as an SP CSI report), after the user equipment receives the first indication and activates the first uplink frequency domain transmission resource, if it is determined that there are multiple PUSCH resource configurations corresponding to the first uplink frequency domain transmission resource, the user equipment may send a CSI report on the first uplink frequency domain transmission resource based on the most recently configured PUSCH resource configuration and the first signal state information CSI report configuration corresponding to the first downlink frequency domain transmission resource. Correspondingly, the network device receives the CSI report on the first uplink frequency domain transmission resource based on the most recently configured PUSCH resource configuration and the first signal state information, CSI, report configuration corresponding to the first downlink frequency domain transmission resource. It can be understood that "most recent configuration" refers to a corresponding PUSCH resource configuration having a configuration generation time closest to the time when the first uplink frequency domain transmission resource is activated.

For a semi-persistent CSI report (which may be denoted as an SP CSI report), after receiving a first indication and activating a first uplink frequency domain transmission resource, if it is determined that a first CSI report configuration exists, the first activation indication is received on the first downlink frequency domain transmission resource, and the first uplink frequency domain transmission resource is determined to be in an activated state, the ue may send a CSI report on the first uplink frequency domain transmission resource based on a physical uplink shared channel, PUSCH, resource configuration corresponding to the first uplink frequency domain transmission resource and a first signal state information, CSI, report configuration corresponding to the first downlink frequency domain transmission resource.

It should be noted that the first activation indication is used to activate sending of a CSI report according to a first CSI report configuration corresponding to a first downlink frequency domain transmission resource, or to activate sending of a CSI report according to a CSI report configuration corresponding to at least one downlink frequency domain transmission resource.

It is to be appreciated that the user equipment may receive the first activation indication and then send the CSI report in a number of different manners. The user equipment receives a first indication to activate the effective time of the first uplink frequency domain transmission resource, which may be before or after the first activation indication.

Optionally, the user equipment may receive the first indication on the first downlink frequency domain transmission resource after receiving the first indication to activate the first uplink frequency domain transmission resource. Referring to fig. 2 and fig. 3, taking the frequency domain transmission resource as the bandwidth part, for example, the network device has configured the SP CSI report of the downlink bandwidth part DL BWP through RRC and has activated on the first downlink bandwidth part DL BWP, when the network device instructs to switch the uplink bandwidth part UL BWP to the first uplink bandwidth part UL BWPj and the first uplink bandwidth part is in an activated state after the switching time, the user equipment UE stops sending the SP CSI report. Correspondingly, the network device also stops receiving. And only when the network device reactivates the SP CSI report on the first downlink bandwidth segment DL BWP and indicates the PUSCH resource, and the user equipment receives the second activation indication and the first PUSCH resource indication on the first downlink bandwidth segment DL BWP, the user equipment UE sends the SP CSI report on the first uplink bandwidth segment UL BWPj based on the PUSCH resource indicated in the first PUSCH resource indication and according to the first SP CSI report configuration (reporting setting) corresponding to the first downlink bandwidth segment DL BWP. Correspondingly, the network side can receive.

It can be understood that the second activation indication is used to activate sending of CSI reports according to the first CSI reporting configuration corresponding to the first downlink frequency domain transmission resource; the first PUSCH resource indication is used for indicating PUSCH resources occupied by sending CSI reports on the first uplink frequency domain transmission resources, and the PUSCH resources comprise at least one of time domain position and frequency domain transmission resources.

Optionally, as shown in the timing diagram of fig. 4, when the ue receives an indication, switches the uplink frequency domain transmission resource to the first uplink frequency domain transmission resource, and the first uplink frequency domain transmission resource is in an active state after the switching time, the ue may send the SP CSI report according to the SP CSI report configuration corresponding to the downlink frequency domain transmission resource (e.g., DL BWP) and the PUSCH resource corresponding to the RRC-configured first uplink frequency domain transmission resource (e.g., UL BWPj) without reactivation, until the ue receives a deactivation indication, stop sending the CSI report on the first uplink frequency domain transmission resource, where the deactivation indication is used to stop sending the CSI report on at least one uplink frequency domain transmission resource. It can be understood that the at least one uplink frequency domain transmission resource herein includes a first uplink frequency domain transmission resource.

In addition, aperiodic CSI reporting AP-CSI reporting is triggered by DCI, which contains a CSI request field (CSIrequest field).

The PUSCH-based SP-CSI report is activated by the SP-CSI RNTI scrambled DCI. The CSI request field (CSI request field) in DCI may be utilized, but not as meaningful as the AP-CSI report:

the DCI triggers AP-CSI reporting: the CSI request field indicates the trigger state of the AP-CSI report to be triggered (trigger state, or report trigger)

DCI activates PUSCH-based SP-CSI reporting: the CSI request field indicates the SP-CSI reporting configuration number that needs to be activated.

In the embodiment of the invention, when the new frequency domain transmission resource is activated, the signal can be sent and received according to the configuration information corresponding to the new frequency domain transmission resource, so that the wireless communication is uninterrupted. When the network device sends the semi-persistent CSI report based on the PUSCH, if a new uplink frequency domain transmission resource is activated, for example, the uplink frequency domain transmission resource is switched to a new bandwidth portion BWP, or a new secondary cell is opened, the user equipment may adopt the semi-persistent CSI report sending method provided in the embodiment of the present invention to send the CSI report without interruption, so as to meet the communication requirement of the wireless communication system.

step 201: sending a first indication on a first downlink frequency domain transmission resource, wherein the first indication is used for activating the first uplink frequency domain transmission resource;

step 203: when a preset condition is met, receiving a CSI report on the first uplink frequency domain transmission resource based on a Physical Uplink Shared Channel (PUSCH) resource configuration corresponding to the first uplink frequency domain transmission resource and a first signal state information (CSI) report configuration corresponding to the first downlink frequency domain transmission resource;

the preset conditions include:

sending first configuration information, wherein the first configuration information comprises PUSCH resource configuration corresponding to at least one uplink frequency domain transmission resource; or,

and sending second configuration information, wherein the second configuration information comprises PUSCH resource configurations corresponding to all uplink frequency domain transmission resources.

when it is determined that there are multiple PUSCH resource configurations corresponding to the first uplink frequency domain transmission resource, receiving the CSI report on the first uplink frequency domain transmission resource based on a most recently configured PUSCH resource configuration and a first signal state information (CSI) report configuration corresponding to the first downlink frequency domain transmission resource.

when a first PUSCH resource indication is sent on the first downlink frequency domain transmission resource, receiving the CSI report on the first uplink frequency domain transmission resource based on a PUSCH resource indicated in the first PUSCH resource indication and the first CSI report configuration;

the first PUSCH resource indication is used for indicating a PUSCH resource occupied by user equipment for sending the CSI report on the first uplink frequency domain transmission resource, and the PUSCH resource comprises at least one of a time domain position and a frequency domain transmission resource.

Optionally, the method further includes:

when a deactivation indication is sent, stopping receiving the CSI report on the first uplink frequency domain transmission resource; the deactivation indication is used to stop receiving the CSI report on at least one uplink frequency domain transmission resource, where the at least one uplink frequency domain transmission resource includes the first uplink frequency domain transmission resource.

Optionally, the downlink frequency domain transmission resource includes at least one of a downlink bandwidth part BWP and a downlink secondary cell; the uplink frequency domain transmission resource includes at least one of an uplink bandwidth part BWP and an uplink secondary cell.

It can be understood that the interaction between the network device and the user equipment described in the network device side is the same as that described in embodiment 1, and is not described herein again to avoid repetition.
