Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
For the purpose of clearly and specifically describing the embodiments of the present invention, the related art of the embodiments of the present invention will be described first. The 3GPP LTE-a Rel-10/11 is an enhancement of LTE Rel-8 technology, and in order to meet the requirement of LTE-a, the LTE-a system uses Carrier Aggregation (CA) technology as its method for expanding system bandwidth, and largely adopts Multiple Input and Output (MIMO) enhancement technology and adaptive technology to improve data rate and system performance. In an LTE-A Rel-10 carrier aggregation scenario, one UE can support up to 5 CCs. In an LTE-a system, a UE needs to feed back CSI to an eNB, where the CSI includes a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Rank Indicator (RI), and the like. The base station determines a Modulation and Coding Scheme (MCS) used for downlink according to the received feedback information, and implements Adaptive Modulation and Coding (AMC), that is, dynamically selects an appropriate Modulation and Coding Scheme according to the change of channel conditions.
In an LTE-a system, reporting of CSI includes two types, namely triggered reporting and periodic reporting, where the triggered reporting mainly feeds back on a Physical Uplink Shared Channel (PUSCH) resource, the periodic reporting mainly feeds back on a Physical Uplink Control Channel (PUCCH), and the triggered CSI is a supplement to the periodic CSI.
The triggered reporting is also called aperiodic reporting, and the triggered reporting mainly sends an Uplink (UL) scheduling grant (grant) signaling to the UE through an eNB in a Downlink Physical Downlink Control Channel (PDCCH for short), where the UL grant signaling includes a "CSI request" field, and triggers the UE to report aperiodic CSI when the field is valid. The UL grant signaling herein includes a Downlink Control Information (DCI) format (format)0 and a DCI format 4.
Rel-10 supports 6 standard bandwidths in total: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20 MHz. The CC used by Rel-10 for carrier aggregation is a backward compatible carrier, can independently exist, is the same as Rel-8/9 from the perspective of a single carrier, and can be used by users of Rel-8/9. Some non-backward compatible carriers may be supported in Rel-11, which may be standard or non-standard bandwidth. The Extended CCs and Segment CCs introduced in Rel-11 may not have synchronization signals thereon, including primary synchronization signals and secondary synchronization signals, system messages, paging messages, uplink/downlink control channels, and may only be used for transmitting data and pilot; the pilot includes a Sounding Reference Signal (SRS), a Demodulation Reference Signal (DMRS), a Common Reference Signal (CRS), or a Channel state information Reference Signal (CSI-RS), and if there is CRS, there may not be CSI-RS, and if there is no CRS, CSI-RS may be used for CSI measurement.
In the process of implementing the invention, the inventor finds that: for non-backward compatible extension carriers such as ExtendedCC and Segment CC introduced in Rel-11 version, how to realize triggered reporting of CSI thereof is a problem to be solved. In the embodiment of the invention, the CSI of the extension carrier wave can be reported in a triggering mode by analyzing the CSI request identification in the scheduling signaling sent by the base station, determining the extension carrier wave requesting to report and sending the CSI of the extension carrier wave. Embodiments of the present invention may be implemented using the process illustrated in fig. 2.
Fig. 2 is a flowchart illustrating an information reporting method according to a first embodiment of the present invention. As shown in fig. 2, the method includes:
step 201, receiving a scheduling signaling sent by a base station device;
for example, the UE receives scheduling signaling sent by the base station equipment. The scheduling signaling may be implemented by using a method in the prior art, for example, the physical layer uplink scheduling grant signaling UL grant includes DCIformat 0/4, which is not limited in this embodiment. Generally, the scheduling signaling is sent to the UE by the base station through a Physical Downlink control channel (PDCCH for short). The PDCCH is divided into two search spaces: a Common Search Space (CSS) for transmitting Common control information of all UEs, and a UE-specific Search Space (USS) for transmitting control information of a specific UE.
Step 202, determining an extension carrier attached to an independent carrier as a reporting carrier based on the scheduling signaling;
the extension carrier herein refers to non-backward compatible carriers introduced by 3GPP LTE-A Rel-11 and later releases, including Extended CC, Segment CC, etc. The extension carrier may have one or more extension carriers, and may be extension CC, Segment CC, or a combination of extension CC and Segment CC, which is not limited in this embodiment.
Specifically, the reported carrier may be determined to be an extended carrier based on a certain field in the scheduling signaling, for example, a CSI request field, an extended indicator bit, or based on a combination of several fields, for example, a CSI request identifier and an extended indicator bit, which is not limited in this embodiment.
And 203, sending the CSI of the reported carrier.
Here, the CSI of the extension carrier serving as the reporting carrier may be obtained according to a method in the prior art, for example, by measuring the CRS or CSI-RS, which is not limited in this embodiment.
The embodiment of the invention adopts the technical means of receiving the scheduling signaling sent by the base station equipment, determining the extension carrier attached to the independent carrier as the reporting carrier based on the scheduling signaling, and sending the CSI of the reporting carrier, so that the aperiodic CSI of the extension carrier can be reported based on the triggering of the base station equipment, and the triggering type CSI reporting of the extension carrier is realized.
Fig. 3 is a flowchart illustrating a second embodiment of an information reporting method according to an embodiment of the present invention. As shown in fig. 3, the method includes:
step 301, receiving a first control signaling sent by a base station device, where the first control signaling includes a first carrier identifier;
the first Control signaling may be implemented by Radio Resource Control (RRC) layer signaling. In application, a unique carrier identifier may be configured for all independent carriers. The first carrier identification here is the carrier identification of the independent carrier. The independent carrier refers to a carrier which is introduced by 3GPP LTE-A Rel-11 and previous releases and can exist independently.
Step 302, determining a downlink carrier corresponding to the first carrier identifier as an independent carrier according to the first carrier identifier;
generally, the transmission period of the control signaling is longer than that of the scheduling signaling, and when the user equipment receives the control signaling, the carrier indicated by the control signaling is configured as a carrier to be triggered. The determining that the downlink carrier is the independent carrier specifically means determining that the downlink carrier is the independent carrier related to triggering the report.
Step 303, receiving a scheduling signaling sent by the base station device, where the scheduling signaling includes a CSI request identifier;
the CSI request identifier can implement that different values of the CSIrequest field correspond to different reporting requests through the CSI request field of the UL grant signaling, and at least one of the values of the CSI request field corresponds to an extended carrier requesting reporting. For example, if the scheduling signaling is issued through the CSS, the CSI request field may be 1bit (bit), and further, when the value of the field is set to be 1, it indicates that the base station requests the UE to report the CSI of the extension carrier; if the scheduling signaling is issued by the USS, the CSIrequest field may be 2bits, and further, when the value of the field is set to 10 or 11, the base station requests the UE to report the CSI of the extension carrier. This embodiment is not limited to this.
Step 304, determining an extension carrier attached to the independent carrier as a reporting carrier according to the CSI request identifier;
here, all extension carriers that are requested to be reported and are attached to the independent carrier may be determined according to the CSI request identifier, where the all extension carriers include all Extended CCs and/or all segmentccs. For example, when the CSI request field corresponding to the CSI request identifier is 2bits, it may be set that when the value of the CSI request field is 10, all Extended CCs attached to the independent carrier are requested to be reported, when the value of the CSI request field is 11, all Segment CCs attached to the independent carrier are requested to be reported, and when the value of the CSI request field is 01, all Extended CCs and all Segment CCs attached to the independent carrier are requested to be reported. This embodiment is not limited to this.
Optionally, it may also be determined that an Extended carrier attached to the independent carrier is requested to be reported according to the CSI request identifier, where the Extended carrier includes an Extended CC or a Segment CC. For example, when the CSI request field corresponding to the CSI request identifier is 2bits, it may be set that when the value of the CSI request field is 10, the ue requests to report an Extended CC attached to the independent carrier, and when the value of the CSI request field is 11, the ue requests to report a Segment CC attached to the independent carrier. This embodiment is not limited to this.
And 305, sending the CSI of the reported carrier.
In application, the base station device may further trigger the independent carrier and the extension carrier attached to the independent carrier to report together, where in this scenario, step 304 further includes: determining the independent carrier as another reporting carrier according to the CSI request identifier; correspondingly, step 305 further includes: and sending the CSI of the other reporting carrier.
For example, all extension carriers and the independent carrier that depend on the independent carrier that are requested to be reported may be determined according to the CSI request identifier, where the extension carriers include all Extended CCs and/or all Segment CCs. For example, when the CSIrequest field corresponding to the CSI request identifier is 2bits, the CSI request field may be set to request reporting of all Extended CCs attached to the independent carrier and the independent carrier when the value of the CSIrequest field is 10, the CSI request field may request reporting of all Segment CCs attached to the independent carrier and the independent carrier when the value of the CSI request field is 11, and the CSI request field may request reporting of all Extended CCs attached to the independent carrier, all Segment CCs attached to the independent carrier and the independent carrier when the value of the CSIrequest field is 01. This embodiment is not limited to this.
For example, an extension carrier and the independent carrier that depend on the independent carrier and are requested to be reported may be determined according to the CSI request identifier, where the extension carrier includes an Extended CC or a SegmentCC. For example, when the CSIrequest field corresponding to the CSI request identifier is 2bits, the CSI request field may be set to 10 to request reporting of an Extended CC attached to the independent carrier and the independent carrier, and when the CSI request field is set to 11 to request reporting of a Segment CC attached to the independent carrier and the independent carrier. This embodiment is not limited to this.
Under the scenario of requesting to report CSI of a certain specified extension carrier, an independent carrier identifier may also be configured for each extension carrier in advance, and accordingly, the first control signaling further includes at least one second carrier identifier, where the second carrier identifier is a carrier identifier of an extension carrier;
step 304 specifically includes: and determining at least one extension carrier corresponding to the at least one second carrier identifier as the reporting carrier in a plurality of extension carriers attached to the independent carrier according to the CSI request identifier.
For example, when the CSI request field corresponding to the CSI request identifier is 2bits, the CSI irequest field may be set to take a value of 10 to request reporting of the extended carrier indicated by the carrier identifier in the control signaling, which is not limited in this embodiment.
The embodiment of the invention adopts the technical means of receiving the control signaling sent by the base station equipment, wherein the control signaling comprises the carrier identifier of the independent carrier, analyzing the CSI request identifier in the scheduling signaling, determining the extension carrier attached to the independent carrier as the reporting carrier, and sending the CSI of the reporting carrier, so that the aperiodic CSI of the extension carrier attached to a certain independent carrier can be reported based on the triggering of the base station equipment, and the triggering type CSI reporting of the extension carrier is realized. Further, the independent carrier can be used as another reporting carrier according to the CSI request identifier, so that the independent carrier and the aperiodic CSI of the extension carrier are reported together.
Fig. 4 is a flowchart illustrating a third embodiment of an information reporting method according to an embodiment of the present invention. As shown in fig. 4, the method includes:
step 401, receiving a scheduling signaling sent by a base station device, where the scheduling signaling includes a CSI request identifier and a fourth carrier identifier;
for example, a Carrier Identifier Field (CIF) of the UL grant signaling may carry the fourth Carrier identifier.
Step 402, determining a downlink carrier corresponding to the fourth carrier identifier according to the fourth carrier identifier, and taking the downlink carrier corresponding to the fourth carrier identifier as an independent carrier;
in application, the carrier corresponding to the fourth carrier identifier is usually a carrier scheduled in uplink, which is also referred to as an uplink carrier. Specifically, the uplink carrier corresponding to the fourth carrier identifier may be determined according to the fourth carrier identifier; and acquiring a downlink carrier matched with the uplink carrier as the downlink carrier corresponding to the fourth carrier identifier. Taking the downlink carrier as an independent carrier specifically means that the downlink carrier is taken as an independent carrier related to triggering and reporting.
Step 402 can be implemented by a method in the prior art, for example, according to a System Information (SI) sent by the base station device, such as a type 2 System Information block (2)ndSystem Information Block, abbreviated as SIB2), and determines a downlink carrier paired with the uplink carrier. The downlink carrier is usually a stand-alone carrier.
Step 403, determining an extension carrier attached to the independent carrier as a reporting carrier according to the CSI request identifier;
here, all extension carriers that are requested to be reported and are attached to the independent carrier may be determined according to the CSI request identifier, where the all extension carriers include all Extended CCs and/or all segmentccs. For example, when the CSI request field corresponding to the CSI request identifier is 2bits, it may be set that when the value of the CSI request field is 10, all Extended CCs attached to the downlink carrier are requested to be reported, when the value of the CSI request field is 11, all Segment CCs attached to the downlink carrier are requested to be reported, and when the value of the CSI request field is 01, all Extended CCs and all Segment CCs attached to the downlink carrier are requested to be reported. This embodiment is not limited to this.
Optionally, it may also be determined that an Extended carrier attached to the independent carrier is requested to be reported according to the CSI request identifier, where the Extended carrier includes an Extended CC or a Segment CC. For example, when the CSI request field corresponding to the CSI request identifier is 2bits, it may be set that when the value of the CSI request field is 10, the ue requests to report an Extended CC attached to the independent carrier, and when the value of the CSI request field is 11, the ue requests to report a Segment CC attached to the independent carrier. This embodiment is not limited to this.
And step 404, sending the CSI of the reported carrier.
In application, the base station device may further trigger the independent carrier and the extension carrier attached to the independent carrier to report together, and in this scenario, step 403 further includes: determining the independent carrier as another reporting carrier according to the CSI request identifier; correspondingly, step 404 further comprises: and sending the CSI of the other reporting carrier.
For example, all extension carriers and the independent carrier that depend on the independent carrier that are requested to be reported may be determined according to the CSI request identifier, where the extension carriers include all Extended CCs and/or all Segment CCs. For example, when the CSIrequest field corresponding to the CSI request identifier is 2bits, the CSI request field may be set to request reporting of all Extended CCs attached to the independent carrier and the independent carrier when the value of the CSIrequest field is 10, the CSI request field may request reporting of all Segment CCs attached to the independent carrier and the independent carrier when the value of the CSI request field is 11, and the CSI request field may request reporting of all Extended CCs attached to the independent carrier, all Segment CCs attached to the independent carrier and the independent carrier when the value of the CSIrequest field is 01. This embodiment is not limited to this.
For example, an extension carrier and the independent carrier that depend on the independent carrier and are requested to be reported may be determined according to the CSI request identifier, where the extension carrier includes an Extended CC or a SegmentCC. For example, when the CSIrequest field corresponding to the CSI request identifier is 2bits, the CSI request field may be set to 10 to request reporting of an Extended CC attached to the independent carrier and the independent carrier, and when the CSI request field is set to 11 to request reporting of a Segment CC attached to the independent carrier and the independent carrier. This embodiment is not limited to this.
In a scenario where reporting of CSI of a specific extension carrier is requested, an independent carrier identifier may be configured for each extension carrier in advance, and accordingly, step 401 may further include:
receiving a second control signaling sent by the base station equipment, wherein the second control signaling comprises at least one third carrier identification;
step 403 specifically includes: and determining at least one extension carrier corresponding to the at least one third carrier identifier as the reporting carrier in a plurality of extension carriers attached to independent carriers according to the CSI request identifier.
For example, when the CSI request field corresponding to the CSI request identifier is 2bits, the CSI irequest field may be set to take a value of 10 to request reporting of the extended carrier indicated by the carrier identifier in the control signaling, which is not limited in this embodiment.
The embodiment of the invention receives a scheduling signaling sent by base station equipment, determines a corresponding downlink carrier as an independent carrier according to a carrier identifier in the scheduling signaling, determines an extension carrier attached to the independent carrier as a reporting carrier according to a CSI request identifier in the scheduling signaling, and sends the CSI of the reporting carrier. Further, the downlink carrier and the aperiodic CSI of the extension carrier thereof can be reported together according to the CSI request identifier.
Fig. 5 is a flowchart illustrating a fourth embodiment of an information reporting method according to an embodiment of the present invention. As shown in fig. 5, the method includes:
step 501, receiving a second control signaling sent by a base station device, where the second control signaling includes at least one third carrier identifier;
step 502, receiving a scheduling signaling sent by the base station equipment, wherein the scheduling signaling contains a CSI request identifier;
step 503, determining at least one extension carrier corresponding to the at least one third carrier identifier as a reporting carrier among a plurality of extension carriers attached to independent carriers according to the CSI request identifier;
for example, when the CSI request field corresponding to the CSI request identifier is 2bits, the CSI irequest field may be set to take a value of 10 to request reporting of at least one extension carrier indicated in the control signaling.
And step 504, sending the CSI of the reported carrier.
In application, step 503 may further include:
determining the independent carrier as another reporting carrier according to the CSI request identifier;
step 504 may also include:
and sending the CSI of the other reporting carrier.
It should be noted that, when the control signaling simultaneously includes the carrier identifier of the independent carrier and the carrier identifier of the extension carrier, the process of the second embodiment of the information reporting method provided in the embodiment of the present invention may be performed. In this scenario, the control signaling preferably only includes a carrier identifier of an independent carrier, and extension carriers corresponding to other carrier identifiers are all attached to the independent carrier.
The embodiment of the invention adopts the technical means of receiving the control signaling sent by the base station equipment, determining the corresponding at least one extension carrier according to at least one carrier identifier in the control signaling, determining the at least one extension carrier as a reporting carrier according to the CSI request identifier in the scheduling signaling, and sending the CSI of the reporting carrier, so that the triggered CSI reporting of the extension carrier can be realized based on the aperiodic CSI of the at least one extension carrier configured by the triggering reporting control signaling of the base station equipment. Further, a group of carriers including at least two extension carriers and independent carriers attached to the extension carriers can be configured through control signaling, so that aperiodic CSI of the group of carriers can be triggered to be reported together.
Fig. 6 is a flowchart illustrating a fifth embodiment of an information reporting method according to an embodiment of the present invention. As shown in fig. 6, the method includes:
step 601, receiving a scheduling signaling sent by base station equipment, wherein the scheduling signaling comprises a CSI request identifier and an extension indicator bit;
the extension indication bit may be implemented by adding a field to the UL grant, or by adding a bit to the CSI request field. For example, the CSI request field in the UL grant sent by the USS may be 2bits, and in this embodiment, a 1-bit extended request extensendrequest field is added to the UL grant sent by the USS as an extended indicator bit. Or, the CSI request field in the UL grant sent by the USS may be 2bits, in this embodiment, 1bit is added to the CSI request field to be used as an extension indicator, and another 2bits is used as a CSI request identifier. In this embodiment, no limitation is made on which field of the scheduling signaling is used as the extension indication bit, or in which field a bit is added, and how many bits are added to be used as the extension indication bit.
Step 602, determining an extension carrier attached to an independent carrier as a reporting carrier according to the CSI request identifier and an extension indicator bit;
here, the CSI request identity and the extension indication bit may be jointly parsed as a whole. For example, the CSIrequest field has 3bits, the first bit is an extension indicator bit, and the last two bits are CSI request identifiers, for example, if the CSI request field takes the value of 110 or 111, it indicates that the base station device requests the UE to report CSI of an extension carrier attached to an independent carrier.
Step 603, sending the CSI of the reported carrier.
Optionally, in step 602, the CSI request flag and the extended indication bit may be separately parsed, for example: determining an independent carrier as a reporting carrier according to the CSI request identifier; and if the extension indicating bit is a preset value, determining an extension carrier attached to the independent carrier as another reporting carrier. For example, the CSI request flag is 01 to trigger reporting of the aperiodic CSI of the certain independent carrier, and the extension indicator bit is 1 to trigger reporting of the aperiodic CSI of the extension carrier, so that the combination may indicate triggering of reporting of the aperiodic CSI of the certain independent carrier and the extension carrier.
Of course, the scheduling signaling in this embodiment may also only include an extension indicator, and in step 602, an extension carrier attached to the independent carrier is determined as a reporting carrier according to the extension indicator. For example, the extension indicator bit is 1bit, and if the extension indicator bit is 1, it indicates that the extension carrier attached to the independent carrier is reported as the reporting carrier. The independent carrier to which the extension carrier specifically depends can be determined by the configuration of the control signaling or the CIF of the scheduling signaling with reference to the above embodiment; specifically, which extension carrier/extension carriers depend on the independent carrier may also be determined by the configuration of the control instruction with reference to the above embodiment; this embodiment is not limited to this.
The embodiment of the invention adopts the technical means of receiving the scheduling signaling sent by the base station equipment, determining the extension carrier attached to the independent carrier as the reporting carrier according to the CSI request identifier and the extension indicating bit in the scheduling signaling, and sending the CSI of the reporting carrier, so that the aperiodic CSI of the extension carrier can be reported based on the triggering of the base station equipment, and the triggering type CSI reporting of the extension carrier is realized.
In practical applications, the embodiments of the present invention can be applied in a variety of forms, including but not limited to the following seven forms. The following describes different forms and meanings of the CSI request identifier (i.e., CSI request field) in the scheduling signaling according to the embodiments of the present invention based on various applications.
The first application is as follows: for all extendedccs and all Segment CCs that are Attached to the same independent carrier Attached CC to trigger together, one state representation in the CSI request field in the physical layer signaling ul grant in the PDCCH channel is used.
In the USS, the CSI request field may have two states left for high-level configuration, and one state is taken out, and only one state needs to be left for high-level semi-static configuration. Specifically, the 2bits of the CSI request field in the UL grant sent in the USS is interpreted that if the field is 00, which indicates that aperiodic reporting is not triggered, the field is 01, which indicates that downlink carrier (2 bits) in the SIB2 is triggered to be reported (2 bits)ndSystem Information Block linked Downlink CC, abbreviated as SIB2-linked DL CC), where SIB2-linked DL CC refers to a Downlink carrier paired with an uplink carrier identified by a CIF field in an ul grant set in a System message, where the field indicates that aperiodic CSI reporting of all Extended CCs and all Segment CCs of a certain attach CC is triggered when the field is 10, and indicates that aperiodic CSI reporting of CCs configured by RRC layer signaling is triggered when the field is 11, where the RRC layer signaling may configure any combination of 5 independent carriers compatible with Rel-10, and trigger aperiodic CSI reporting of any 1 to 5 independent carriers among the 5 independent carriers. The specific definition is as follows:
UL dynamic scheduling in USS：
By UL grant scrambling by C-RNTI：
CSI request＝00，Data only
CSI request＝01，
Data+a-CSI(SIB2-linked DL CC)
When MCS＝29and RB＜＝4，a-CSI(SIB2-linked DL CC)only
CSI request＝10，
Data+a-CSI(Extended/Segment CCsof the same Attached CC)
When MCS＝29and RB＜＝4，a-CSI(Extended/Segment CCs of the sameAttached CC)only
CSI request＝11，
Data+a-CSI(a set of DL CC by RRC)
When MCS＝29and RB＜＝4，a-CSI(a set of DL CC by RRC)only
of course, the 11-state of the CSI request field may also be used to indicate that aperiodic CSI reporting of all Extended CCs and all Segment CCs of a certain Attached CC is triggered.
The second application is as follows: the sending of aperiodic CSI of Attached CC is increased on the basis of the first application, that is, for all Extended CCs and all Segment CCs Attached to the same Attached CC and the Attached CC are triggered together, one state in CSI request field in physical layer signaling UL grant in PDCCH channel is used for representing.
Specifically, the interpretation of 2bits of the CSI request field in the UL grant sent in the USS is that when the field is 10, it indicates that an aperiodic CSI report of one attach CC, all Extended CCs thereof, and all Segment CCs is triggered, and the interpretation of other states is the same as that of the first application. The specific definition is as follows:
UL dynamic scheduling in USS：
By UL grant scrambling by C-RNTI：
CSI request＝00，Data only
CSI request＝01，
Data+a-CSI(SIB2-linked DL CC)
When MCS＝29and RB＜＝4，a-CSI(SIB2-linked DL CC)only
CSI request＝10，
Data+a-CSI(One Attached CCand its Extended/Segment CCs)
When MCS＝29and RB＜＝4，a-CSI(One Attached CC and its Extended/Segment CCs)only
CSI request＝11，
Data+a-CSI(a set of DL CC by RRC)
When MCS＝29and RB＜＝4，a-CSI(a set of DL CC by RRC)only
of course, 11 states of the CSI request field may also be used to indicate that aperiodic CSI reporting of a certain Attached CC and all Extended CCs and all Segment CCs thereof is triggered.
The third application is as follows: the extension carrier is divided into Extended CC and Segment CC, and all Extended CC Attached to the same Attached CC is triggered once, or all Segment CC Attached to the same Attached CC is triggered once. Specifically, the 2bits of the UL grant and CSIrequest field sent in the USS is interpreted that when the field is 10, the field indicates that aperiodic CSI reporting of all Extended CCs of a certain Attached CC is triggered, or indicates that aperiodic CSI reporting of all Segment CCs of a certain Attached CC is triggered, and the interpretation of other states is the same as that of the first application.
The fourth application is as follows: and on the basis of the third application, the sending of the aperiodic CSI of the ordered CCs is increased, namely, one ordered CC and all Extended CCs thereof are triggered at one time, or one ordered CC and all Segment CCs thereof are triggered at one time. Specifically, the interpretation of 2bits of the CSI request field in the UL grant sent in the USS is that when the field is 10, it indicates that aperiodic CSI reporting of a certain attach CC and all Extended CCs thereof is triggered, or indicates that aperiodic CSI reporting of a certain attach CC and all Segment CCs thereof is triggered, and the interpretation of other states is the same as that of the first application.
The fifth application is as follows: triggering one Attached CC and one Extended CC at a time, or triggering one Attached CC and non-periodic CSI report of one Segment CC at a time, specifically, which Extended CC/Segment CC is notified to the UE by RRC layer signaling, for the fifth application, each Extended CC/Segment CC is required to be configured with an independent Carrier Identifier (CI) value, so that the CI value of the Extended CC/Segment CC which needs to be triggered can be contained in the RRC layer signaling. The difference between the present application and the fourth application is that only the aperiodic CSI of one Extended CC and one Segment CC is reported for all Extended CCs and all Segment CCs, so that the reporting overhead can be reduced. The Segment CC Attached to the same attach CC has only 2 at most, that is, there is one on each side of the Attached CC, and the two Segment CCs have no difference except for the difference between high and low frequencies in the spectrum position, and if the attach CC is a small bandwidth in the standard bandwidth, the difference between the two is smaller, so that it can be considered that only one Segment CC is reported and the two segments CC share the same bandwidth.
Specifically, the interpretation of 2bits of the CSI request field in the UL grant sent in the USS is that when the field is 10, it indicates that an aperiodic CSI report of a certain Attached CC and an Extended CC is triggered, or indicates that an aperiodic CSI report of a certain Attached CC and a Segment CC is triggered, and the interpretation of other states is the same as that of the first application.
The sixth application is as follows: for the sixth application, each Extended CC/Segment CC needs to be configured with its own independent carrier identifier CI value, so that it is possible to include CI values of all Extended CCs/Segment CCs that need to be triggered in the CC set configured by the RRC layer signaling, and usually, Extended/Segment CCs included in the CC set are all attached to the same independent carrier, and all carriers included in the set of CC sets are triggered together. Specifically, state 1 in the CSI request field in the physical layer signaling UL grant in the CSS space of the PDCCH channel is triggered, or state 10 or 11 in the CSIrequest field in the physical layer signaling UL grant in the USS space of the PDCCH channel is triggered. The specific definition is as follows:
UL dynamic scheduling in CSS：
By UL grant scrambling by C-RNTI：
CSI request＝0，Data only
CSI request＝1，
Data+a-CSI(configured by RRC，Extended and/or Segment CCs of the sameAttached CC can be added to the set)
When MCS＝29and RB＜＝4，a-CSI only
UL dynamic scheduling in USS：
By UL grant scrambling by C-RNTI：
CSI request＝00，Data only
CSI request＝01，
Data+a-CSI(SIB2-linked DL CC)
When MCS＝29and RB＜＝4，a-CSI(SIB2-linked DL CC)only
CSI request＝10，
Data+a-CSI(1st set of DL CC by RRC，Extended and/or Segment CCs of thesame Attached CC can be added to the set)
When MCS＝29and RB＜＝4，a-CSI(1st set of DL CC)only
CSI request＝11，
Data+a-CSI(2nd set of DL CC by RRC Extended and/or Segment CCs ofthesame Attached CC can be added to the set)
When MCS＝29and RB＜＝4，a-CSI(2nd set of DL CC by RRC)only
the sixth application may be used alone or in combination with the above five applications.
The seventh application is as follows: the bit is added to the CSI request field to indicate triggering of aperiodic CSI related to the Extended carrier, specifically, may indicate that a certain Extended CC or Segment CC reports aperiodic CSI, or may be triggering of various combinations of CCs in the first to fifth applications. If a certain Extended CC/Segment CC or certain Extended CCs/Segment CCs needs to be triggered by designation, instead of triggering all Extended CCs and/or Segment CCs of a certain advanced CC, each Extended CC/Segment CC needs to be configured with its own independent carrier identifier CI value, so that the Extended CCs/Segment CCs which need to be triggered may be specifically indicated.
Specifically, bits are added to a CSI request field in a physical layer signaling UL grant transmitted in the USS space of the PDCCH channel. For example, the CSI request field is set to 3bits, where 1bit can be analyzed separately, for example, when the 1bit is 1, it indicates that aperiodic CSI reporting of all Extended CCs of an Attached CC is triggered, and when the 1bit is 0, it indicates that the aperiodic CSI reporting is not triggered; the 1bit can also be jointly parsed with other 2bits, so that there can be more states, for example, one of the definitions can be as follows:
UL dynamic scheduling in USS：
By UL grant scrambling by C-RNTI：
CSI request＝000，Data only
CSI request＝001，
Data+a-CSI(SIB2-linked DL CC)
When MCS＝29and RB＜＝4，a-CSI(SIB2-linked DL CC)only
CSI request＝010，
Data+a-CSI(1st set of DL CC by RRC)
When MCS＝29and RB＜＝4，a-CSI(1st set of DL CC by RRC)only
CSI request＝011，
Data+a-CSI(2nd set of DL CC by RRC)
When MCS＝29and RB＜＝4，a-CSI(2nd set of DL CC by RRC)only
CSI request＝100，
Data+a-CSI(Extended/Segment CCs of the same Attached CC)
When MCS＝29and RB＜＝4，a-CSI(Extended/Segment CCs of the sameAttached CC)only
CSI request＝101，
Data+a-CSI(One Attached CC and its Extended/Segment CCs)
When MCS＝29and RB＜＝4，a-CSI(One Attached CC and its Extended/Segment CCs)only
CSI request＝110，
Data+a-CSI(Extended CCs of the same Attached CC)
When MCS＝29and RB＜＝4，a-CSI(Extended CCs of the same Attached CC)only
CSI request＝111，
Data+a-CSI(One Attached CC and one of its Segment CCs)
When MCS＝29and RB＜＝4，a-CSI(One Attached CC and one of its SegmentCCs)only
of course, other state resolution designs are possible, and the application is not limited.
