Detailed Description

In the existing narrow-band system, available time-frequency resources are few, and periodic feedback is difficult to perform. However, there is no solution in the prior art on how to perform aperiodic feedback in narrowband systems.

In the embodiment of the invention, when the channel quality requirement exists, the channel quality reporting indication is sent to the user equipment, and the uplink channel required by the channel quality is carried is indicated to the user equipment. And receiving the channel quality reported by the user equipment on an uplink channel indicated to the user equipment, thereby realizing the non-periodic feedback of the channel quality.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

An embodiment of the present invention provides a method for reporting channel quality, which is described in detail below with reference to fig. 1 through specific steps.

Step S101, sending channel quality reporting indication to user equipment.

In a specific implementation, when the base station has a requirement for acquiring the channel quality, the base station may issue a channel quality reporting instruction to the user equipment. In the embodiment of the present invention, the channel quality reporting indication issued by the base station to the user equipment may be used to indicate the user equipment to perform channel quality reporting. That is, when the ue receives the channel quality reporting indicator sent by the base station, the ue can perform the channel quality calculation and reporting operations.

In a specific implementation, the content of the Channel quality may be any one or more of a Channel quality indication (CSI), a Reference Signal Receiving Power (RSRP), a Signal to Interference plus Noise Ratio (SINR), and a Physical Downlink Control Channel (PDCCH) repetition number.

In other words, in the embodiment of the present invention, the content of the channel quality may be only any one of CSI, RSRP, SINR, and PDCCH repetition number, or may be two or more of CSI, RSRP, SINR, and PDCCH repetition number.

In a specific implementation, the base station may configure a coverage enhancement level (CE level) for the user equipment in advance, and the user equipment may select any one or more of CSI, RSRP, SINR, and PDCCH repetition number according to the CE level configured in advance. The base station may also configure a Coverage Enhancement mode (CE mode) for the user equipment in advance, and the user equipment may select any one or more of CSI, RSRP, SINR, and PDCCH repetition number according to the CE mode.

When the content of the channel quality is RSRP or SINR, since the user equipment already acquires RSRP or SINR when performing Radio Resource Management (RRM) measurement, after receiving the channel quality reporting instruction, the user equipment can use the acquired RSRP or SINR as the content of the channel quality without recalculating the content of the acquired channel quality, thereby reducing the amount of calculation of the user equipment and improving the speed of channel quality feedback.

In particular implementations, for user equipment at the cell edge, its corresponding RSRP or SINR value may be small. If the RSRP or SINR value is reported as the content of the channel quality, the required bit number is large. For the above scenario, in the embodiment of the present invention, the number of repetitions of the PDCCH may be reported as the content of the channel quality, so as to effectively avoid a large number of bits required for reporting the RSRP or SINR.

In a specific implementation, the base station may indicate, to the ue, the content of the channel quality that the ue needs to report through the MAC CE, or may indicate, to the ue, the content of the channel quality that the ue needs to report through a Radio Resource Control (RRC) signaling. This may improve system flexibility.

Step S102, receiving the channel quality reported by the user equipment on an uplink channel.

In a specific implementation, the base station may indicate, to the ue, an uplink channel required for quality reporting of a bearer channel.

In a specific implementation, after obtaining the channel quality, the user equipment may report the obtained channel quality to the base station on an uplink channel indicated by the base station.

In a specific implementation, the base station may receive, on an uplink channel indicated to the user equipment, channel quality reported by the user equipment, thereby implementing aperiodic feedback of the channel quality.

Therefore, in the embodiment of the invention, when the base station needs the channel quality of the user equipment, the channel quality reporting indication can be issued to the user equipment. The user equipment obtains the corresponding channel quality according to the received channel quality reporting indication and reports the channel quality on the uplink channel indicated by the base station, so that the base station can flexibly indicate the user equipment to report the channel quality according to the requirement and the condition of the uplink channel.

In the specific implementation, if the ue directly feeds back the content of the selected channel quality to be reported, there may be a problem that the overhead of channel quality feedback is large. In order to reduce the feedback overhead of the channel quality, in the embodiment of the present invention, a mapping relationship between the channel quality level and the channel quality may be pre-established, and the mapping relationship is known in advance for the base station and the user equipment.

After obtaining the content of the channel quality, the user equipment may search for a channel quality level corresponding to the obtained content of the channel quality in a mapping relationship between the channel quality level and the channel quality. And then, the user equipment bears the channel quality grade corresponding to the acquired content of the channel quality on the uplink channel indicated by the base station and reports the channel quality grade to the base station. The base station may receive the level corresponding to the channel quality sent by the user equipment on the indicated uplink channel, and may obtain the corresponding channel quality according to the preset mapping relationship between the channel quality level and the channel quality.

In a specific implementation, the level corresponding to the channel quality may be indicated by N bits, where N is a positive integer. The N bits may indicate 2^ N levels. For example, 2 bits may be used to indicate 4 levels. Compared with the method of directly reporting the content corresponding to the channel quality, the method of reporting only the grade corresponding to the channel quality can greatly reduce the feedback overhead.

In a specific implementation, when the content of the channel quality is the PDCCH repetition number, the level corresponding to the channel quality may be: an optional value for PDCCH repetition times.

In the implementation of the present invention, the grade corresponding to the channel quality can also be presented by the code point, and different grades are corresponding to different code points.

In the implementation of the present invention, if the content of the base station indicating the channel quality is SINR and the channel quality is represented by 7 or 8 bits (or the number of bits of the channel quality is 7 or 8), then I_CQI＝I_RS-SINR+1, wherein I_RS-SINRIs an index value of SINR, I_RS-SINR＝0,…,63，I_CQIIndex value, I, for channel quality class_CQI＝1,…,64，I_CQI0 means no calculation.

In the implementation of the present invention, if the content of the base station indicating the channel quality is SINR, and the channel quality is represented by 4 bits (or the number of bits of the channel quality is 4), then I_CQI＝floor(I_RS-SINR/4) +1, wherein I_RS-SINRIs an index value of SINR, I_RS-SINR＝0,…,59，I_CQIIndex value, I, for channel quality class_CQI＝1,…,15，I_CQI0 means no calculation. Wherein floor () is a round-down operation.

In the implementation of the present invention, if the content of the base station indicating the channel quality is RSPR and the channel quality is represented by 7 or 8 bits (or the number of bits of the channel quality is 7 or 8), then I_CQI＝I_RSRP+1, wherein I_RSRPIs an index value of RSRP, I_RSRP＝0,…,97，I_CQIIndex value, I, for channel quality class_CQI＝1,…,98，I_CQI0 means noneAnd (4) calculating.

In the implementation of the present invention, if the content of the base station indicating the channel quality is RSPR and the channel quality is represented by 4 bits (or the number of bits of the channel quality is 4), then I_CQI＝floor(I_RSRP/6) +1, wherein I_RSRPIs an index value of RSRP, I_RSRP＝0,…,89，I_CQIIndex value, I, for channel quality class_CQI＝1,…,15，I_CQI0 means no calculation.

In specific implementation, the base station may indicate the carrier for performing channel quality calculation to the user equipment, so that the base station may flexibly control the user equipment to perform measurement calculation on different carriers. If the base station does not indicate the carrier for performing channel quality calculation to the user equipment, the user equipment may assume the monitored carrier of the PDCCH as the carrier for performing channel quality calculation, so that the user equipment may perform measurement calculation of channel quality in the process of monitoring the PDCCH. The base station indicates the carrier for calculating the channel quality to the user equipment, so that the user equipment and the base station can both clearly determine the carrier corresponding to the channel quality.

In a specific implementation, the base station may indicate the uplink channel required for carrying the channel quality to the user equipment through the MAC CE, or may indicate the uplink channel required for carrying the channel quality to the user equipment through RRC signaling. The base station indicates the uplink channel required by the quality of the bearer channel to the user equipment through the MAC CE or RRC signaling without indicating through the PDCCH or modifying the PDCCH, so that the complexity of a communication system can be reduced.

In a specific implementation, the base station may indicate an uplink channel required to carry the channel quality through 1 bit in the MAC CE. This allows for fast switching selection of different uplink channels.

In a specific embodiment, the base station may indicate that the uplink channel required to carry the channel quality is PUCCH or PUSCH. This can reduce the overhead of the indication information.

In a specific implementation, the base station may indicate to the user equipment that the uplink channel required to carry the channel quality is PUCCH. The reliability can be improved by adopting the PUCCH, and the time delay of channel quality reporting is reduced.

In a specific implementation, when the base station can indicate to the user equipment that the uplink channel required to carry the channel quality is PUCCH, the channel quality is represented by 4 bits.

In a specific implementation, the number of PUCCHs required for carrying channel quality may be multiple, that is, multiple PUCCHs are used for carrying channel quality.

In the embodiment of the present invention, the base station may indicate the number of the plurality of PUCCHs to the user equipment, or the number of the plurality of PUCCHs may be a preset value. The flexibility can be improved by adopting an indication mode, and the signaling overhead can be reduced by adopting a preset value mode. When the base station indicates the number of the plurality of PUCCHs to the user equipment, the base station may indicate the number of the plurality of PUCCHs for carrying channel quality through RRC signaling.

In the embodiment of the present invention, the base station may indicate, to the user equipment, time-frequency location information of multiple PUCCHs for carrying channel quality.

In this embodiment of the present invention, the time-frequency location information of the plurality of PUCCHs may include a carrier index of each PUCCH. In a specific embodiment, the base station may indicate a carrier index of each PUCCH by signaling.

In the embodiment of the present invention, a carrier index corresponding to a first PUCCH is (J +1) mod J, where J is a resource of a PUCCH used for ACK/NACK feedback indicated by a PDCCH, J is an available carrier number of the PUCCH, a carrier index corresponding to a second PUCCH is (J +2) mode J, and so on. Here, the PDCCH may be a PDCCH that schedules a PDSCH carrying signaling, such as MAC CE or RRC signaling, for indicating an uplink channel required to carry channel quality. In this way, the parameters of the PUCCH for ACK/NACK feedback indicated by the PDCCH can be reused, and the signaling overhead is reduced. Wherein mod is a modulus or remainder taking operation, Amod B is a remainder taken by dividing a by B, and the purpose of modulus taking is to make J +1 or J +2 not greater than (or equal to) J after modulus taking, thereby ensuring the validity of operation.

In this embodiment of the present invention, the time-frequency location information of the plurality of PUCCHs may include a time delay of each PUCCH and a repetition number of each PUCCH. In a specific embodiment, the base station may indicate the time delay of each PUCCH and the number of repetitions of each PUCCH through signaling.

In the embodiment of the present invention, the time delay corresponding to the first PUCCH is k0+ M, the number of repetitions is M, where k0 is the time delay of the PUCCH for ACK/NACK feedback indicated by the PDCCH, M is the number of repetitions of the PUCCH for ACK/NACK feedback indicated by the PDCCH, the time delay corresponding to the second PUCCH is k0+ 2M, the number of repetitions is M, and so on. Here, the PDCCH may be a PDCCH that schedules a PDSCH carrying signaling, such as MAC CE or RRC signaling, for indicating an uplink channel required to carry channel quality. In this way, the parameters of the PUCCH for ACK/NACK feedback indicated by the PDCCH can be reused, and the signaling overhead is reduced.

In the embodiment of the present invention, for each PUCCH, there is an information bit corresponding to the PUCCH, and each PUCCH includes at least one information bit. And combining the information bits corresponding to all PUCCHs to obtain the channel quality reported by the user equipment.

In the embodiment of the present invention, the information bits carried by the first PUCCH are Least Significant Bits (LSBs) of the channel quality, the information bits carried by the first PUCCH are second Least Significant bits of the channel quality, and so on.

For example, if the base station indicates to the user equipment that the number of PUCCHs used for carrying channel quality is 4, information bits corresponding to a first PUCCH is 1, information bits corresponding to a second PUCCH is 1, information bits corresponding to a third PUCCH is 1, and information bits corresponding to a fourth PUCCH is 0, the channel quality reported by the user equipment is 0111.

In a specific implementation, since the channel quality reported by the ue may be a level of the channel quality, information bits corresponding to multiple PUCCHs may be combined to obtain the level of the channel quality. Therefore, the level of the channel quality reported by the user equipment is 0110. The base station may look for the corresponding channel quality according to 0110.

In a specific implementation, the base station may indicate to the user equipment that the uplink channel required to carry the channel quality is PUSCH. The use of PUSCH may improve flexibility, i.e. the base station may select PUSCH transmission resources depending on the resource status.

In a specific implementation, when the base station can indicate to the user equipment that the uplink channel required to carry the channel quality is PUSCH, the channel quality is represented by 7 or 8 bits. Therefore, the PUSCH can carry a plurality of bits, and the reporting precision is improved. In a specific implementation, when the base station can indicate to the user equipment that the uplink channel required to carry the channel quality is PUSCH, the channel quality is represented by 6 or 7 or 8 bits. When the channel quality is represented using a 6-bit table, overhead can be more saved.

In the embodiment of the present invention, the base station may indicate the time-frequency location information of the PUCSH for carrying the channel quality to the user equipment.

In the embodiment of the present invention, the time-frequency location information of the PUSCH required for carrying the channel quality may include the starting carrier index and the number of carriers of the PUSCH. In a specific embodiment, the base station may indicate the starting carrier index through the MAC CE and indicate the number of carriers through RRC signaling. In a specific embodiment, the base station may indicate the starting carrier index through the MAC CE and indicate the number of carriers through the MAC CE. In a specific embodiment, the base station may indicate the starting carrier index through RRC signaling, and indicate the number of carriers through RRC signaling.

In the embodiment of the present invention, the time-frequency location information of the PUSCH required for carrying the channel quality may include the time delay and the repetition number of the PUSCH. In a specific embodiment, the base station may indicate the time delay through the MAC CE and indicate the number of repetitions of the PUSCH through RRC signaling. In a specific embodiment, the base station may indicate the time delay through the MAC CE, and indicate the number of repetitions of the PUSCH through the MAC CE. In a specific embodiment, the base station may indicate the time delay through RRC signaling, and indicate the number of repetitions of the PUSCH through RRC signaling.

In the embodiment of the present invention, when indicating the PUSCH to the user equipment, the base station may indicate the MCS information of the PUSCH to the user equipment.

In a specific implementation, the channel quality may be carried by a MAC PDU contained in the PUSCH; the base station may obtain the channel quality from the MAC PDU included in the received PUSCH. The channel quality can also be carried by the MAC CE included in the PUSCH; the base station may obtain the channel quality from the MAC CE included in the received PUSCH. Channel quality may also be carried by RRC signaling contained in PUSCH; the base station may obtain the channel quality from the RRC signaling contained in the received PUSCH.

In a specific implementation, the channel quality may also be encoded as a MAC PDU contained in the PUSCH; and the base station decodes the MAC PDU contained in the received PUSCH to acquire the channel quality. The channel quality may be encoded as the PUSCH-inclusive MACCE; and the base station decodes the MAC CE contained in the received PUSCH to acquire the channel quality. Channel quality may also be encoded as RRC signaling contained in PUSCH; and the base station decodes the RRC signaling contained in the received PUSCH to acquire the channel quality.

In the embodiment of the present invention, when the PUSCH is used to carry the channel quality, the PUSCH can carry a larger data size, and therefore, the channel quality with a larger number of bits can be fed back. In addition, the channel quality can be multiplexed with data on the PUSCH, and the utilization rate of channel resources is improved.

After receiving the channel quality reporting instruction issued by the base station, the ue may perform the channel quality acquisition and reporting operations, that is, perform the following steps S202 to S203.

In the embodiment of the invention, the user equipment can flexibly select more suitable channel quality for reporting according to different coverage enhancement degrees or coverage enhancement modes.

In a specific implementation, the base station may indicate, to the user equipment, the content of the channel quality that the user equipment needs to report through the MAC CE, or may indicate, to the user equipment, the content of the channel quality that the user equipment needs to report through the RRC signaling. The user equipment can obtain the content of the channel quality to be reported through the MAC CE, and can also obtain the content of the channel quality to be reported through the RRC signaling. This may improve system flexibility.

Step S202, calculating channel quality.

In a specific implementation, after acquiring the channel quality reporting indication, the ue may perform an operation of calculating the channel quality.

In particular implementations, the base station may indicate to the user equipment the carrier on which the channel quality calculation is performed. The base station may also indicate, to the user equipment, the carrier on which the channel quality calculation is performed as a carrier corresponding to a PDCCH monitored by the user equipment. The user equipment can know the channel quality corresponding to which carriers are calculated according to the indication of the base station.

In a specific implementation, the ue may also default to a currently monitored PDCCH carrier as a carrier for performing channel quality calculation.

In the specific implementation, if the ue receives the cqi reporting indication, the nth frame of the ue starts to calculate the cqi, where n is a frame number of the ue that completes receiving the cqi reporting indication. Therefore, the user equipment starts to calculate the channel quality only when receiving the indication, and unnecessary calculation is reduced.

In a specific implementation, the ue does not need to report the channel quality from the nth frame to the (n + K) th frame, where n is a frame number indicating that the ue completes receiving the channel quality report, and K is a calculation interval indicated by a higher layer signaling or a preset calculation interval, which takes a frame as a unit. In a specific embodiment, K > 4. Therefore, the interval time between calculation and reporting of the user equipment can be reserved, and the user equipment is prevented from being too late to calculate the channel quality.

Step S203, reporting the channel quality on an uplink channel.

In a specific implementation, the base station indicates an uplink channel required for carrying channel quality, and the user equipment acquires the uplink channel required for carrying channel quality.

In a specific implementation, the ue may report the obtained channel quality to the base station on an uplink channel indicated by the base station. The base station can receive the channel quality reported by the user equipment on the uplink channel indicated to the user equipment, thereby realizing the non-periodic feedback of the channel quality.

In a specific implementation, the base station may indicate, to the user equipment, an uplink channel required for quality of a bearer channel through the MAC CE, and the user equipment may determine, through the MAC CE issued by the base station, the uplink channel required for quality of the bearer channel. The base station can also indicate the uplink channel required by the quality of the bearer channel to the user equipment through the RRC signaling, and the user equipment can determine the uplink channel required by the quality of the bearer channel through the RRC signaling sent by the base station. Therefore, the PDCCH does not need to be indicated, and the PDCCH does not need to be modified, so that the complexity of the communication system can be reduced.

In a specific implementation, the base station may indicate, to the user equipment, the uplink channel required for the bearer channel quality through one bit of the MAC CE, and the user equipment may determine, through one bit of the MAC CE issued by the base station, the uplink channel required for the bearer channel quality. In a specific embodiment, the uplink channel required to carry the channel quality may be selected from one of PUCCH and PUSCH. This can reduce the overhead of the indication information.

In a specific implementation, the base station may indicate that the uplink channel required to carry the channel quality is PUCCH. The user equipment can acquire the uplink channel required for bearing the channel quality as the PUCCH. The reliability can be improved by adopting the PUCCH, and the time delay of channel quality reporting is reduced.

In the embodiment of the present invention, the base station may indicate the number of the plurality of PUCCHs to the user equipment, or the number of the plurality of PUCCHs may be a preset value. The flexibility can be improved by adopting an indication mode, and the signaling overhead can be reduced by adopting a preset value mode. The user equipment can acquire the number of the plurality of PUCCHs according to the indication or the preset value of the base station, so as to further acquire the uplink channel required by the quality of the bearer channel according to the time-frequency position information of the PUCCHs.

In the embodiment of the present invention, the base station may indicate, to the user equipment, time-frequency location information of multiple PUCCHs for carrying channel quality. The user equipment can acquire the time-frequency position information of each PUCCH according to the indication of the base station, so that an uplink channel required by the quality of the bearer channel is acquired.

The time-frequency location information of the plurality of PUCCHs may be a starting carrier index. In a specific embodiment, the user equipment may obtain the carrier index of each PUCCH through signaling.

In the embodiment of the present invention, a carrier index corresponding to a first PUCCH is (J +1) mod J, where J is a resource of a PUCCH used for ACK/NACK feedback indicated by a PDCCH, J is an available carrier number of the PUCCH, a carrier index corresponding to a second PUCCH is (J +2) mod J, and so on. Here, the PDCCH may be a PDCCH that schedules a PDSCH carrying signaling, such as MAC CE or RRC signaling, for indicating an uplink channel required to carry channel quality. In this way, the parameters of the PUCCH for ACK/NACK feedback indicated by the PDCCH can be reused, and the signaling overhead is reduced. Wherein mod is a modulus or remainder taking operation, Amod B is a remainder taken by dividing a by B, and the purpose of modulus taking is to make J +1 or J +2 not greater than (or equal to) J after modulus taking, thereby ensuring the validity of operation.

The time-frequency location information of the plurality of PUCCHs may include a time delay of each PUCCH and a number of repetitions of each PUCCH. In a specific embodiment, the user equipment may acquire the time delay of each PUCCH and the number of repetitions of each PUCCH through signaling.

In the embodiment of the present invention, the time delay corresponding to the first PUCCH is k0+ M, the number of repetitions is M, where k0 is the time delay of the PUCCH for ACK/NACK feedback indicated by the PDCCH, M is the number of repetitions of the PUCCH for ACK/NACK feedback indicated by the PDCCH, the time delay corresponding to the second PUCCH is k0+2 × M, the number of repetitions is M, and so on. Here, the PDCCH may be a PDCCH that schedules a PDSCH carrying signaling, such as MAC CE or RRC signaling, for indicating an uplink channel required to carry channel quality. In this way, the parameters of the PUCCH for ACK/NACK feedback indicated by the PDCCH can be reused, and the signaling overhead is reduced.

For each PUCCH there is an information bit corresponding to it, each PUCCH containing at least one information bit. And combining the information bits corresponding to all PUCCHs to obtain the channel quality reported by the user equipment.

In the embodiment of the present invention, the information bits carried by the first PUCCH are Least Significant Bits (LSBs) of the channel quality, the information bits carried by the second PUCCH are second Least Significant bits of the channel quality, and so on.

In a specific implementation, since the channel quality reported by the ue may be a level corresponding to the channel quality, information bits corresponding to multiple PUCCHs may be combined to obtain the level corresponding to the channel quality. Therefore, the level corresponding to the channel quality reported by the user equipment is 0110. The base station may look for the corresponding channel quality according to 0110.

In a specific implementation, the base station may indicate that the uplink channel required to carry the channel quality is PUSCH. The user equipment can acquire an uplink channel required for bearing the channel quality as a PUSCH. The use of PUSCH may improve flexibility, i.e. the base station may select PUSCH transmission resources depending on the resource status.

In a specific implementation, when an uplink channel required by the user equipment to acquire the bearer channel quality is a PUSCH, the channel quality is represented by 7 or 8 bits. Therefore, the PUSCH can carry a plurality of bits, and the reporting precision is improved. In a specific implementation, when an uplink channel required by the user equipment to acquire the bearer channel quality is a PUSCH, the channel quality is represented by 6 or 7 or 8 bits. Using 6 bits may save more overhead.

In the embodiment of the present invention, the base station may indicate the time-frequency location information of the PUSCH to the user equipment. The user equipment can acquire corresponding PUSCH time-frequency position information according to the indication of the base station.

In the embodiment of the present invention, the time-frequency location information of the PUSCH required for carrying the channel quality may be the starting carrier index and the number of carriers of the PUSCH. In a specific embodiment, the ue may obtain the starting carrier index through the MAC CE indication, and obtain the number of carriers through the RRC signaling indication. In a specific embodiment, the ue may obtain the starting carrier index through the MAC CE indication, and obtain the number of carriers through the MAC CE indication. In a specific embodiment, the ue may obtain the starting carrier index through an RRC signaling instruction, and obtain the number of carriers through an RRC signaling instruction.

In the embodiment of the present invention, the time-frequency location information of the PUSCH required for carrying the channel quality may be the time delay and the repetition number of the PUSCH. In a specific embodiment, the ue may indicate the acquisition time delay through the MACCE, and indicate the number of repetitions of acquiring the PUSCH through RRC signaling. In a specific embodiment, the ue may indicate the acquisition time delay through the MAC CE, and indicate the number of repetitions of acquiring the PUSCH through the MAC CE. In a specific embodiment, the user equipment may indicate the acquisition time delay through RRC signaling, and indicate the number of repetitions of acquiring the PUSCH through RRC signaling.

In a specific implementation, the channel quality may be carried by a MAC PDU contained in the PUSCH; the base station may obtain the channel quality from the MAC PDU included in the received PUSCH. The channel quality may be carried by the MAC CE contained in the PUSCH; the base station may obtain the channel quality from the MAC CE included in the received PUSCH. Channel quality may also be carried by RRC signaling contained in PUSCH; the base station may obtain the channel quality from the RRC signaling contained in the received PUSCH.

In a specific implementation, the channel quality may also be encoded as a MAC PDU contained in the PUSCH; and the base station decodes the MAC PDU contained in the received PUSCH to acquire the channel quality. The channel quality may also be encoded as PUSCH-inclusive MACCE; and the base station decodes the MAC CE contained in the received PUSCH to acquire the channel quality. Channel quality may also be encoded as RRC signaling contained in PUSCH; and the base station decodes the RRC signaling contained in the received PUSCH to acquire the channel quality.
