In an increasingly scarce environment of spectrum resources, a wideband communication system for realizing a discrete comb spectrum based on a discrete narrowband carrier aggregation technology without changing the original frequency point allocation is generated.
In a new wireless broadband communication system supporting discrete narrowband carrier aggregation, a channel in a specific frequency band (e.g., 223-235MHz frequency band) and taking narrowband spectrum resources (e.g., 25 kHz) as a unit is called a carrier.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the novel wireless broadband communication system supporting discrete narrowband carrier aggregation, the novel terminal only supports quality measurement on currently used carrier resources, measurement cannot be performed on all carriers in a full frequency band, and CQI measurement results reported by the novel terminal are average measurement results of a plurality of carriers, reporting granularity is coarse, and dynamic scheduling and interference avoidance of the novel base station are not facilitated. In this regard, the embodiment of the invention provides a channel quality measurement reporting method of a novel wireless broadband communication system. Fig. 1 is a flow chart of a channel quality measurement reporting method of a novel wireless broadband communication system according to an embodiment of the present invention, as shown in fig. 1, an execution body of the method is a terminal in the system, that is, a novel terminal, and the method includes:
Step 110, receiving a channel quality reporting instruction sent by a base station; the channel quality reporting instruction comprises the information of the to-be-reported carrier wave and the to-be-reported format. The to-be-reported carrier information comprises to-be-reported carrier group identification and/or to-be-reported carrier group set identification.
Wherein, the base station is a novel base station in a novel wireless broadband communication system supporting discrete narrowband carrier aggregation. When the base station needs to acquire the channel quality measurement result, a channel quality reporting instruction can be sent to the terminal to instruct the terminal to report the measured channel quality.
In order to refine the reporting granularity, the full bandwidth carriers or partial bandwidth carriers are grouped in advance to obtain a plurality of carrier groups, and the carrier group identifier to be reported, which is included in the channel quality reporting instruction, is the identifier of the carrier group that needs to report the channel quality, where the carrier group identifier to be reported may be a group name or a group number of the carrier group to be reported, and the embodiment of the invention is not limited in particular. On the basis of grouping full bandwidth carriers or partial bandwidth carriers to obtain a plurality of carrier groups, for convenience in measurement and reporting, the carrier groups can be further grouped to obtain a plurality of carrier group sets, and each carrier group set comprises a plurality of carrier groups. The to-be-reported carrier group set identifier is an identifier of a carrier group set to be reported on channel quality, where the to-be-reported carrier group set identifier may be a set name or a set number of the to-be-reported carrier group set, which is not limited in particular in the embodiment of the present invention. In addition, the channel quality reporting instruction also comprises a format to be reported. The format to be reported is the format adopted by the terminal appointed by the base station when reporting the channel quality measurement result.
Step 120, if the carrier type corresponding to the to-be-reported carrier information is a working carrier, measuring channel quality data of the working carrier corresponding to the to-be-reported carrier information; and if the carrier type is a non-working carrier, measuring channel quality data of the non-working carrier corresponding to the carrier information to be reported in a non-service transmission period.
Specifically, after receiving the channel quality reporting instruction, the carrier information to be reported can be extracted therefrom, so as to determine a carrier group or a carrier group set to be reported. Here, the set of carriers to be reported may be one set or may be multiple sets, and the set of carriers to be reported may be one set or may be multiple sets.
For any to-be-reported carrier group or carrier group set, the carrier type of the to-be-reported carrier group or carrier group set can be determined to be an operating carrier or a non-operating carrier through the carrier type of the to-be-reported carrier group or carrier group set carried in the channel quality reporting instruction or by self judgment. The working carrier refers to a carrier supported by the terminal, and the non-working carrier is all or part of the rest carriers except the working carrier in the novel wireless broadband communication system relative to the working carrier.
If the to-be-reported carrier group or carrier group set is a working carrier, the terminal does not need to carry out carrier adjustment, and can directly carry out channel quality measurement on the to-be-reported carrier group or carrier group set to acquire channel quality data; if the carrier group to be reported or the carrier group set is a non-working carrier, the terminal needs to adjust the carrier to the non-working carrier when the terminal is in a non-service transmission period, that is, the terminal does not have service transmission, and measure the channel quality data of the non-working carrier. Here, the channel quality data may be represented by a CQI (Channel Quality Indicator, channel quality indication) value, or may be represented by the remaining parameters such as SINR (Signal to Interference plus Noise Ratio, signal to noise ratio).
And step 130, generating quality report information based on the format to be reported and the channel quality data.
Specifically, after the channel quality test is completed, the channel quality data can be filled into a format to be reported, so as to obtain quality reporting information. Here, the quality reporting information, that is, the information format is the format to be reported, and includes the information of the channel quality data corresponding to the carrier group to be reported or the carrier group set.
And 140, sending the quality report information to the base station.
Specifically, after the quality report information is obtained, the quality report information is sent to the base station, so that the base station can accurately extract channel quality data corresponding to each to-be-reported carrier group or carrier group set from the quality report information based on the to-be-reported format. Here, the transmission of the quality report information may be implemented by a media access Control (MEDIA ACCESS Control, MAC) Control unit (CE).
According to the method provided by the embodiment of the invention, the information of the carrier to be reported is obtained through the channel quality reporting instruction, so that the measurement and reporting of the channel quality data of the working carrier or the non-working carrier are realized, the base station can acquire the interference condition of each carrier resource, and the dynamic scheduling and interference avoidance are better carried out. In addition, the carrier information to be reported is obtained to determine the carrier group needing to report the channel quality, and the division of the carrier group is helpful to refine the reporting granularity of the channel quality, so that the dynamic scheduling of the base station is further optimized.
Based on the above embodiment, in the method, step 130 specifically includes: and filling the channel quality data corresponding to each to-be-reported carrier group identifier into the channel quality field in the to-be-reported format in sequence to generate quality reporting information.
Fig. 2 is a schematic structural diagram of a format to be reported including a channel quality field according to an embodiment of the present invention, in fig. 2, oct represents an 8-bit group byte (ottet), one byte includes 8 bits (bits), where LCID is a logical channel ID, and a field length is 3 bits; the P/C field is used to indicate whether the quality report information specifically reports PHR (Power Headroom Report ) or CQI, and the field length is 2 bits. The channel quality field is the field labeled CQI in fig. 2. The CQI is used for indicating channel quality data corresponding to the to-be-reported carrier group identifiers, namely CQI values, and the length of a CQI field corresponding to each to-be-reported carrier group identifier is 6 bits, and the CQI fields are arranged according to the size sequence of the to-be-reported carrier group identifiers. In fig. 2, the length of the channel quality field is 8×k bits, that is, the channel quality report instruction includes k to-be-reported carrier group instructions, and correspondingly, the quality report information includes a channel quality field formed by k CQI field lengths. R is a padding bit, set to "0", and is padded to achieve byte alignment in the channel report information.
Based on any of the above embodiments, the method in step 130 specifically includes: and filling any carrier group identifier to be reported into a carrier group identifier field in a format to be reported, filling channel quality data corresponding to the carrier group identifier to be reported into a channel quality field in the format to be reported, and generating quality reporting information corresponding to the carrier group identifier to be reported.
Fig. 3 is a schematic structural diagram of a format to be reported including a carrier Group identifier field and a channel quality field according to an embodiment of the present invention, where in fig. 3, a Group ID is a carrier Group identifier field, and is used to indicate a carrier Group corresponding to channel quality data included in quality reporting information. In the format to be reported shown in fig. 3, the carrier group identifier field is used to carry any one of the carrier group identifiers to be reported, and the subsequent channel quality field is used to carry the channel quality data corresponding to the carrier group identifier to be reported, that is, one of the carrier group identifiers to be reported corresponds to one of the quality reporting information.
Correspondingly, step 140 specifically includes: and sequentially sending the quality reporting information corresponding to each to-be-reported carrier group identifier to the base station.
Specifically, if the channel quality reporting indication includes a plurality of to-be-reported carrier group identifiers, a plurality of quality reporting information is correspondingly generated, and each quality reporting information needs to be sent to the base station.
Based on any of the above embodiments, the method in step 130 specifically includes: and filling any carrier group set identifier to be reported into a carrier group set identifier field in the format to be reported, sequentially filling channel quality data of each carrier group corresponding to the carrier group set identifier to be reported into a channel quality field in the format to be reported, and generating quality reporting information corresponding to the carrier group set identifier to be reported.
Fig. 4 is a schematic structural diagram of a format to be reported including a carrier Group Set identifier field and a channel quality field according to an embodiment of the present invention, and in fig. 4, a Group Set ID, that is, a carrier Group Set identifier field, is used to indicate a carrier Group Set corresponding to channel quality data included in quality report information. In the format to be reported shown in fig. 4, the carrier group set identifier field is used to carry any one of the carrier group set identifiers to be reported, and the subsequent channel quality field, i.e., CQI 1、CQI2、…、CQIl, is used to sequentially carry the channel quality data of each carrier group corresponding to the carrier group identifier to be reported.
When quality report information corresponding to any one of the carrier group set identifiers to be reported is generated, each carrier group in the carrier group set to be reported needs to be sequentially filled into the channel quality field according to the order of the carrier group numbers from small to large.
Correspondingly, step 140 specifically includes: and sequentially sending the quality reporting information corresponding to each to-be-reported carrier group set identifier to the base station.
Specifically, in the quality report information generated based on the format to be reported shown in fig. 4, one set identifier of the carrier group to be reported corresponds to one quality report information. If the channel quality reporting indication includes a plurality of to-be-reported carrier group set identifiers, a plurality of quality reporting information are correspondingly generated, and each quality reporting information needs to be sent to the base station.
Based on any of the above embodiments, the method further includes, before step 130: and if the channel quality data corresponding to any to-be-reported carrier group identifier is not measured, taking the special identifier field as the channel quality data corresponding to the to-be-reported carrier group identifier.
Specifically, before generating quality report information based on the format to be reported and the channel quality data, it is necessary to determine whether the channel quality data corresponding to the identifier of the to-be-reported carrier group has been measured or not: and if the channel quality data corresponding to the to-be-reported carrier group identifier is not measured, taking the special identifier field as the channel quality data corresponding to the to-be-reported carrier group identifier. The special identification field characterizes the unavailable measurement result, the special identification field is used as channel quality data to be filled into a format to be reported, after quality reporting information is generated and sent to the base station, the base station can identify the special identification field and obtain that the corresponding carrier group to be reported represents the unavailable measurement result.
For example, in the format to be reported shown in fig. 2, channel quality data corresponding to each to-be-reported carrier group identifier needs to be sequentially filled into a channel quality field, if a measurement result corresponding to any to-be-reported carrier group identifier is unavailable, a special identifier field is filled into the format to be reported as channel quality data, so that the channel quality data corresponding to each to-be-reported carrier group identifier in the channel quality field is ensured to be sequentially filled, and the problem that a base station cannot obtain a correct measurement result due to sequence disorder when analyzing the channel quality data corresponding to each to-be-reported carrier group identifier due to lack of the channel quality data corresponding to a certain to-be-reported carrier group identifier is avoided.
Based on any of the above embodiments, the method in step 130 specifically includes:
step 131, if any channel quality data corresponding to the to-be-reported carrier group identifier exists, the reporting identifier corresponding to the to-be-reported carrier group identifier is set to be reported, otherwise, the reporting identifier is set to be not reported.
Specifically, the reporting identifier is used for indicating whether to fill the channel quality data corresponding to the to-be-reported carrier group identifier into the to-be-reported format reporting base station. And aiming at any to-be-reported carrier group identifier, if the channel quality data of the to-be-reported carrier group identifier is measured, setting the reporting identifier as reporting, and if the channel quality data of the to-be-reported carrier group identifier is not measured, setting the reporting identifier as not reporting.
And 132, sequentially filling the reporting identifiers corresponding to the group identifiers of the carriers to be reported into a group index field in a format to be reported, sequentially filling the channel quality data corresponding to the group identifiers of the carriers to be reported, which are reported as reported, into a channel quality field in the format to be reported, and generating quality reporting information.
Fig. 5 is a schematic structural diagram of a to-be-reported format including a group index field and a channel quality field according to an embodiment of the present invention, in fig. 5, G 1、G2、…、Gl sequentially represents a reporting identifier corresponding to each to-be-reported carrier group identifier, and G 1、G2、…、Gl forms the group index field. The group index field is used for indicating the group identifier of the to-be-reported carrier corresponding to each channel quality field of the channel quality fields in the quality report information. The existence of the group index field enables that only the channel quality data of the to-be-reported carrier group identifier with reporting identifier as reporting is filled in the channel quality field, and the channel quality data of the to-be-reported carrier group identifier with reporting identifier as not reporting is not filled in. That is, due to the existence of the group index field, only the measured channel quality data of the to-be-reported carrier group identifier is filled in the channel quality field, and no special field is needed to replace the unmeasured channel quality data of the to-be-reported carrier group identifier, thereby improving the resource utilization rate.
Based on any of the above embodiments, the method further includes a step 132: for any to-be-reported carrier group set identifier, filling any to-be-reported carrier group set identifier into a carrier group set identifier field in a to-be-reported format, sequentially filling reporting identifiers corresponding to each to-be-reported carrier group identifier contained in the to-be-reported carrier group set identifier into a group index field in the to-be-reported format, sequentially filling channel quality data corresponding to each to-be-reported carrier group identifier which is reported into the to-be-reported format into a channel quality field in the to-be-reported format, and generating quality reporting information corresponding to the to-be-reported carrier group set identifier.
Fig. 6 is a schematic structural diagram of a format to be reported, including a carrier Group Set identifier field, a Group index field, and a channel quality field, where the format to be reported shown in fig. 6 corresponds to any one of the carrier Group Set identifiers to be reported, and the carrier Group Set ID is used to indicate a carrier Group Set corresponding to channel quality data included in quality reporting information, the Group index field G 1、G2、…、Gl is used to sequentially indicate a reporting identifier of each carrier Group corresponding to the carrier Group Set identifier to be reported, and the channel quality field CQI 1、…、CQIl is used to sequentially indicate channel quality data of a carrier Group whose reporting identifier is reported in the carrier Group Set identifier to be reported.
Based on any of the above embodiments, the method further includes step 130: filling a carrier type identifier corresponding to the carrier type into a carrier type identifier field in a format to be reported; the carrier type identification field is a logical channel ID or P/C field.
Specifically, the to-be-reported format described with reference to fig. 2 to 6 may further include LCID and/or P/C fields. The LCID is a logical channel ID, and the P/C field is used to indicate whether the quality report information specifically reports PHR or CQI. Both LCID and P/C fields may be used as carrier type identification fields for carrying carrier type identifications. Here, the carrier type identifier is a carrier type for indicating a carrier group corresponding to the channel quality data filled into the format to be reported, and the carrier type may be an operating carrier or a non-operating carrier.
For example, when LCID is used as the carrier type identification field, it may be defined that when LCID is valued at 101, the corresponding carrier type is an active carrier, and when LCID is valued at 100, the corresponding carrier type is a non-active carrier. For another example, when the P/C field is used as the carrier type identification field, it may be defined that when the P/C field value is 00, the reporting information is PHR, when the P/C field value is 01, the reporting information is CQI, and the corresponding carrier type is an operating carrier, and when the P/C field value is 11, the reporting information is CQI, and the corresponding carrier type is a non-operating carrier. In addition, when the LCID is used as the carrier type identification field, the to-be-reported format may not include the P/C field.
