[0040] The embodiments of the present disclosure provide a channel state information (CSI) report configuration processing method and apparatus, a communication device, a communication system, and a storage medium.

[0041] In a first aspect, an embodiment of the present disclosure provides a method for processing a channel state information (CSI) report configuration, wherein the method includes:

[0042] The network device sends a media access control MAC control unit CE to the terminal; wherein the MAC CE includes a first MAC CE; the first MAC CE carries first information, wherein the first information is used to indicate activation or deactivation of a sub-configuration of a CSI reporting configuration.

[0043] In the above embodiment, the network device sends a first MAC CE to the terminal and uses the first information in the first MAC CE to indicate the activation or deactivation of the sub-configuration of the CSI report configuration, thereby realizing activation or deactivation based on the sub-configuration. Therefore, compared with the CSI report configuration, a finer-grained activation or deactivation is realized, which can reduce the measurement power consumption of the terminal and save bit overhead.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, the first MAC CE includes:

[0045] At least one first-category bit is used to indicate activation or deactivation of the subconfiguration.

[0046] In the above embodiment, at least one first-class bit is carried by the first MAC CE. On the one hand, the CSI report reporting of the terminal is activated by the first MAC CE. On the other hand, the activation or deactivation of the sub-configuration is indicated by at least one first-class bit in the first MAC CE, so as to realize activation or deactivation based on the sub-configuration.

[0047] In combination with some embodiments of the first aspect, in some embodiments, the first MAC CE further includes:

[0048] At least one second type bit, used to indicate activation or deactivation of the CSI reporting configuration;

[0049] Among them, the first type of bits are specifically used to indicate the activation or deactivation of the sub-configuration in the activated CSI reporting configuration.

[0050] In the above embodiment, the first MAC CE also includes at least one second-type bit for indicating the activation or deactivation of the CSI report configuration. Through the first-type bits and the second-type bits, at least one activated CSI report configuration and the activation or deactivation of the sub-configuration within the activated CSI report configuration can be indicated, so that the terminal can more accurately know the CSI report configuration and specific sub-configuration adopted by the CSI report to be reported, reduce the measurement power consumption of the terminal, and save bit overhead.

[0051] In conjunction with some embodiments of the first aspect, in some embodiments, the first MAC CE includes:

[0052] The third type of bit; wherein, the first bit value of the third type of bit is used to indicate that the MAC CE is the first MAC CE.

[0053] In the above embodiment, the first MAC CE also carries a third type of bit, and different bit values ​​of the third type of bit are used to indicate the type of MAC CE, so that after the terminal determines that the MAC CE is the first MAC CE based on the bit value of the third type of bit in the received MAC CE, it further obtains the activation or deactivation of the sub-configuration indicated by the first MAC CE.

[0054] In combination with some embodiments of the first aspect, in some embodiments, the MAC CE also includes a second MAC CE; the second bit value of the third category bit indicates that the MAC CE is the second MAC CE; the second MAC CE is used to indicate activation or deactivation of the CSI reporting configuration.

[0055] In the above embodiment, the network device may also send a second MAC CE to the terminal to indicate the activation or deactivation of the CSI reporting configuration. The second MAC CE also carries a third type of bit. Different bit values ​​of the third type of bit are used to distinguish the first MAC CE and the second MAC CE, so that the terminal can activate or deactivate CSI reporting configurations of different granularities according to the different types of MAC CEs received.

[0056] In combination with some embodiments of the first aspect, in some embodiments, the at least one first-category bit is a bitmap, wherein one bit in the bitmap is used to indicate activation or deactivation of one of the subconfigurations; or

[0057] The at least one first-category bit is joint indication information, wherein a sequence value of the at least one first-category bit is used to indicate a combination relationship of activation or deactivation of multiple sub-configurations, wherein the sequence value can be composed of the bit values ​​of each bit of the at least one first-category bit.

[0058] In the above embodiment, at least one first-category bit may indicate the activation or deactivation of at least one sub-configuration within the CSI reporting configuration via a bitmap, thereby utilizing the correspondence between bits in the bitmap and sub-configurations, effectively reducing the decoding complexity of the first-category bits within the first MAC CE. Alternatively, at least one first-category bit may indicate the activation or deactivation of at least one sub-configuration within the CSI reporting configuration via joint indication information, thereby utilizing a smaller number of first-category bits to indicate a greater number of combined activation or deactivation relationships of sub-configurations, effectively reducing the number of bits occupied by the first MAC CE.

[0059] In conjunction with some embodiments of the first aspect, in some embodiments, the first type of bits and the second type of bits are located in different octets of the first MAC CE;

[0060] The first type of bits carried by one of the octets are used to indicate the activation or deactivation of a sub-configuration of the CSI reporting configuration indicated by one of the second type of bits.

[0061] In the above embodiment, by carrying the first type of bits and the second type of bits in different octets within the first MAC CE, the terminal can first decode the octet containing the second type of bits when decoding the first MAC CE, and then selectively decode the octet carrying the first type of bits based on the decoding result of the second type of bits, thereby reducing the decoding amount of the terminal and improving decoding efficiency.

[0062] In conjunction with some embodiments of the first aspect, in some embodiments, the bits of the first MAC CE constitute N octets: N is a positive integer greater than or equal to 3;

[0063] The first octet of the first MAC CE is used to indicate at least a serving cell identifier and / or a partial bandwidth BWP identifier;

[0064] The second type of bits are located in the second octet of the first MAC CE;

[0065] The first type of bits are located in the nth octet of the first MAC CE;

[0066] Wherein, n is a positive integer greater than or equal to 3 and less than or equal to N.

[0067] In the above embodiment, at least one octet is added to the existing MAC CE, wherein the at least one newly added octet carries the first type of bits. This allows the terminal to determine the activated CSI reporting configuration based on the octet in which the second type of bits are located when decoding the first MAC CE, and to determine the octet associated with the activated CSI reporting configuration among the multiple octets carrying the first type of bits, so as to decode the first type of bits of the octet and obtain the activation or deactivation of the sub-configuration within the activated CSI reporting configuration, thereby reducing the decoding amount of the terminal and improving decoding efficiency.

[0068] In combination with some embodiments of the first aspect, in some embodiments, the identifier corresponding to the CSI report configuration mapped from the third octet to the Nth octet of the first MAC CE gradually increases; or,

[0069] The identifiers corresponding to the CSI reporting configurations mapped from the 3rd octet to the Nth octet of the first MAC CE gradually decrease.

[0070] In the above embodiment, the identifier of the CSI report configuration mapped from the 3rd octet to the Nth octet of the first MAC CE may show a trend of gradually increasing or decreasing, thereby improving the format flexibility of the first MAC CE.

[0071] In conjunction with some embodiments of the first aspect, in some embodiments, the first MAC CE includes M octets; wherein M is a positive integer greater than or equal to 2;

[0072] The first type of bits are located in the mth octet of the first MAC CE; wherein m is greater than or equal to 2 and less than or equal to M;

[0073] The first type of bits in one of the octets are used to indicate activation or deactivation of a sub-configuration in the CSI reporting configuration.

[0074] In the above embodiment, the first MAC CE includes multiple octets, and the first type of bits are located in multiple octets other than the first octet in the first MAC CE. Multiple octets carrying the first type of bits are directly used. On the one hand, the first type of bits are used to indicate the activation or deactivation of a sub-configuration in the CSI report configuration. On the other hand, the activation or deactivation of the CSI report configuration corresponding to the octet can also be indicated. Therefore, there is no need to carry the second type of bits in the first MAC CE, which reduces the number of bits occupied by the first MAC CE and reduces the signaling overhead.

[0075] In combination with some embodiments of the first aspect, in some embodiments, the identifier corresponding to the CSI report configuration mapped from the second octet of the first MAC CE to the Mth octet gradually increases, or,

[0076] The identifiers corresponding to the CSI reporting configurations mapped from the 2nd octet to the Mth octet of the first MAC CE gradually decrease.

[0077] In the above embodiment, the identifier corresponding to the CSI report configuration mapped from the 2nd octet to the Mth octet of the first MAC CE may show a trend of gradually increasing or decreasing, thereby improving the format flexibility of the first MAC CE.

[0078] In combination with some embodiments of the first aspect, in some embodiments, a second-category bit is used to indicate activation or deactivation of the CSI reporting configuration;

[0079] An octet of the first MAC CE includes at least one first-category bit and one second-category bit; wherein,

[0080] The first-category bit adjacent to the nth second-category bit and located in the same octet is used to indicate the activation or deactivation of the sub-configuration in the CSI report configuration corresponding to the nth second-category bit.

[0081] In the above embodiment, by simultaneously carrying the first type of bits and the second type of bits in an octet of the first MAC CE, the first type of bits in the same octet adjacent to the second type of bits are used to indicate the activation or deactivation of the sub-configuration within the CSI reporting configuration corresponding to the second type of bits, so that when the terminal decodes the first MAC CE, it can determine whether the CSI reporting configuration corresponding to the second type of bits is activated based on the second type of bits in an octet. When the CSI reporting configuration corresponding to the second type of bits is activated, at least one first type of bit adjacent to the second type of bits is decoded to determine the activation or deactivation of the CSI reporting configuration corresponding to the second type of bits, thereby improving the decoding efficiency of the terminal.

[0082] In conjunction with some embodiments of the first aspect, in some embodiments, one of the octets includes two bits of the second category;

[0083] The two second-category bits in one octet are spaced apart, and one second-category bit corresponds to X first-category bits; X is a positive integer greater than or equal to 1.

[0084] In the above embodiment, by carrying two second-class bits in an octet within the first MAC CE and distributing the two second-class bits at intervals, the first-class bits adjacent to the second-class bits are used to indicate the activation or deactivation of the sub-configuration within the CSI report configuration indicated by the adjacent second-class bits. This can effectively improve the decoding efficiency of the terminal on the one hand, and on the other hand, effectively reduce the number of bits occupied by the first MAC CE while ensuring that the first MAC CE can indicate the activation or deactivation of more sub-configurations within the CSI report configuration.

[0085] In combination with some embodiments of the first aspect, in some embodiments, the logical channel LCID of the first MAC CE is different from the LCID of the second MAC CE, wherein the second MAC CE is used to indicate activation or deactivation of the CSI reporting configuration.

[0086] In the above embodiment, the first MAC CE and the second MAC CE are distinguished by the LCID carried in the header of the MAC PDU or the header of the MAC sub-PDU where the MAC CE is located. On the one hand, it is convenient for the terminal to directly determine the type of MAC CE according to the LCID, and on the other hand, it does not need to occupy the bits of the MAC CE.

[0087] In combination with some embodiments of the first aspect, in some embodiments, the first type of bits are reserved bits of the first MAC CE.

[0088] In the above embodiment, bits are reserved in the existing MAC CE to enable activation or deactivation of CSI reporting at a sub-configuration granularity, thereby enabling finer-grained configuration of CSI reporting without modifying the format of the existing MAC CE.

[0089] In conjunction with some embodiments of the first aspect, in some embodiments, the first MAC CE has a first octet and a second octet;

[0090] The third type of bits are reserved bits of the first octet; and the first type of bits are reserved bits of the second octet.

[0091] In the above embodiment, the type of MAC CE is indicated by the reserved bit in the first octet in the existing MAC CE, and the activation or deactivation of the sub-configuration in the CSI reporting configuration is indicated by the reserved bit in the second octet in the existing MAC CE. Without modifying the format of the existing MAC CE, it is possible to indicate the type of MAC CE and implement a more fine-grained configuration of the CSI report.

[0146] In some embodiments, for activating or deactivating a MAC CE for SP CSI reporting, as shown in FIG1B , FIG1B is a schematic structural diagram of a MAC CE according to an exemplary embodiment.

[0147] The serving cell ID (Serving Cell ID) indicates the ID of the serving cell to which the MAC CE is applicable; the length of this field is 5 bits.

[0148] Bandwidth Part (BWP) ID indicates the uplink BWP applied by the MAC CE, as the code point of the Downlink Control Information DCI Bandwidth Part Indicator field specified in TS 38.212 [9]. The length of this field is 2 bits;

[0149] Si: This field indicates the activation / deactivation status of the semi-persistent CSI reporting configuration in the CSI reporting configuration (CSIReportConfigToAddModList), as specified in TS 38.331 [5].

[0150] S0 refers to the CSI reporting configuration that includes PUCCH resources for SP CSI reporting in the indicated BWP and has the smallest CSI configuration identifier (ReportConfigId) within the list whose type is set to semi-persistent ON PUSCH.

[0151] S1 refers to a reporting configuration containing PUCCH resources for SP-CSI reporting in the indicated BWP and having a second lower CSI configuration identifier (ReportConfigId), and so on.

[0152] If the number of reporting configurations in the list whose type is set to semi-persistent ON PUSCH in the indicated BWP is less than i+1, the MAC CE shall ignore the Si field.

[0153] When the Si field is set to 1, it indicates that the corresponding semi-persistent CSI reporting configuration should be activated. When the Si field is set to 0, it indicates that the corresponding semi-persistent CSI reporting configuration will be deactivated.

[0154] FIG2 is an interactive diagram illustrating a method for configuring and processing a channel state information (CSI) report according to an exemplary embodiment. As shown in FIG2 , an embodiment of the present disclosure relates to a method for configuring and processing a channel state information (CSI) report, which is used in a communication system 100 and includes:

[0155] Step S2101: The network device sends a MAC CE to the terminal.

[0156] In some embodiments, the terminal receives a MAC CE sent by a network device.

[0157] In some embodiments, the network device may include but is not limited to an access network device.

[0158] In some embodiments, the terminal may be any type of communication device. The terminal may be a mobile terminal or a fixed terminal. For example, the terminal may be a mobile phone, a tablet computer, a smart office device, a smart home device, a vehicle-mounted device, and / or an aircraft device.

[0159] In some embodiments, the MAC CE is used to activate or deactivate reporting of a Semi-Persistent Channel State Information (SP-CSI) report.

[0160] In some embodiments, the MAC CE is used to activate or deactivate the reporting of SP-CSI reports with different configuration granularities.

[0161] In some embodiments, the MAC CE may include one of the following:

[0162] First MAC CE;

[0163] Second MAC CE.

[0164] In some embodiments, the first MAC CE is used to activate or deactivate the reporting of CSI reports with sub-configuration granularity.

[0165] In some embodiments, the second MAC CE is used to activate or deactivate reporting of CSI reports with CSI report configuration as the granularity.

[0166] In some embodiments, a sub-configuration of a CSI reporting configuration corresponds to a spatial pattern (SD) element and / or transmit power consumption.

[0167] It should be noted that each CSI reporting configuration may include multiple sub-configurations; each sub-configuration may be associated with a spatial pattern (SD) and / or multiple power consumption (power) standards.

[0168] The first MAC CE can activate the reporting of CSI reports with sub-configuration granularity, that is, the first MAC CE can be used to activate a part of the sub-configuration within a CSI reporting configuration and deactivate another part of the sub-configuration of the CSI reporting configuration. The second MAC CE can activate the reporting of CSI reports with configuration granularity, that is, the second MAC CE can only activate or deactivate the entire CSI reporting configuration (all sub-configurations within the CSI reporting configuration). The two different types of MAC CEs have different configuration granularities for activating or deactivating CSI reports.

[0169] In order to facilitate the terminal to determine whether the received MAC CE is the first MAC CE or the second MAC CE, in some embodiments, the MAC CE includes: a third type of bit.

[0170] In some embodiments, the first bit value of the third type of bits is used to indicate that the MAC CE is the first MAC CE.

[0171] In some embodiments, the second bit value of the third type of bits is used to indicate that the MAC CE is a second MAC CE.

[0172] It should be noted that the first MAC CE and the second MAC CE can be distinguished by different bit values ​​of the third type of bits.

[0173] In some embodiments, the third type of bits may be reserved bits within a MAC CE.

[0174] It is worth noting that the reserved bits in the MAC CE can be directly used to distinguish the first MAC CE from the second MAC CE by using different bit values ​​of the reserved bits. In this embodiment, the third type of bits can be carried in the MAC CE as the body content of the MAC CE.

[0175] In other embodiments, the first MAC CE and the second MAC CE may be distinguished based on a logical channel identifier (LCID) of the MAC CE.

[0176] In some embodiments, the LCID of the first MAC CE is different from the LCID of the second MAC CE.

[0177] It should be noted that the header of the MAC protocol data unit (Protocol Data Unit, PDU) where the MAC CE is located or the header of the MAC sub-PDU may include an LCID field, and the LCID carried in the LCID field may be used to indicate whether the MAC CE is the first MAC CE or the second MAC CE.

[0178] In some embodiments, the first MAC CE and the second MAC CE may be indicated respectively based on two different reserved code points of the LCID field.

[0179] It should be noted that the LCID field may include multiple bits. For example, the LCID field may include 8 bits, which may have 64 code points. For example, code points 37-42 and 47 of the 64 code points are reserved. In the embodiments of the present disclosure, these reserved code points may be used to indicate the first MAC CE and the second MAC CE.

[0180] In some embodiments, the first MAC CE may include: at least one first type bit, used to indicate activation or deactivation of a sub-configuration.

[0181] In some embodiments, the at least one first type bit is a bitmap, wherein one bit in the bitmap is used to indicate activation or deactivation of one of the subconfigurations.

[0182] It should be noted that at least one first-class bit may indicate the activation or deactivation of at least one subconfiguration within the CSI reporting configuration via a bitmap. Each bit in the bitmap corresponds to a subconfiguration, and different bits carry specific bit values ​​to indicate the activation or deactivation of the subconfiguration corresponding to the bit.

[0183] It is worth noting that the method of indicating the activation or deactivation of the sub-configuration based on the bit map can effectively reduce the decoding complexity of the first type of bits in the first MAC CE. However, since one bit in the bit map corresponds to one sub-configuration, the number of sub-configurations that can be activated or deactivated by the first type of bits in the first MAC CE is limited by the number of first type bits in the first MAC CE.

[0184] For example, the first MAC CE includes: 4 first-category bits, and the first MAC CE can only indicate activation or deactivation of 4 sub-configurations.

[0185] In some embodiments, the at least one first-category bit is joint indication information, wherein a sequence value of the at least one first-category bit is used to indicate a combined relationship of activation or deactivation of multiple sub-configurations, wherein the sequence value can be composed of the bit values ​​of each bit of the at least one first-category bit.

[0186] It should be noted that at least one first-class bit in the first MAC CE constitutes an indicator sequence; different sequence values ​​of the indicator sequence are used to indicate different combination relationships of activation or deactivation of multiple sub-configurations in the CSI reporting configuration.

[0187] In some embodiments, a mapping relationship between different sequence values ​​of at least one first-class bit and different combination relationships of activation or deactivation of multiple sub-configurations within the CSI reporting configuration can be pre-configured; thereby, a sequence value formed by at least one first-class bit is used to indicate a combination relationship of activation or deactivation of multiple sub-configurations within a CSI reporting configuration.

[0188] It is worth noting that the manner in which the activation or deactivation of a subconfiguration is indicated based on the joint indication information can effectively increase the number of different situations in which the at least one first-class bit can indicate the activation or deactivation of multiple subconfigurations. By using a smaller number of first-class bits to indicate more combined relationships of subconfiguration activation or deactivation, the number of bits occupied by the first MAC CE can be effectively reduced.

[0189] For example, the first MAC CE includes: 4 first-class bits, and the 4 first-class bits constitute an indication sequence with 16 different sequence values; thereby, the different sequence values ​​of the indication sequence are used to indicate different combination relationships of activation or deactivation of all sub-configurations within the CSI reporting configuration.

[0190] In some embodiments, the first MAC CE further includes: at least one second-category bit, used to indicate activation or deactivation of the CSI reporting configuration; wherein the first-category bit is used to indicate activation or deactivation of a sub-configuration in the activated CSI reporting configuration.

[0191] It should be noted that the activation or deactivation of the CSI reporting configuration corresponding to the second type of bit can be indicated by different bit values ​​of the second type of bit; further, the activation or deactivation of the sub-configuration corresponding to the first type of bit in the activated CSI reporting configuration can be indicated by different bit values ​​of the first type of bit.

[0192] In some embodiments, the second type of bits may be S bits in an existing MAC CE.

[0193] It should be noted that the S bits in the existing MAC CE may be 4 bits, namely S0 to S3. It is understandable that S0 to S3 correspond to different CSI reporting configurations.

[0194] The first MAC CE may have multiple different optional structures, and several optional embodiments are provided below.

[0195] Optional embodiment one:

[0196] In some embodiments, the first MAC CE has a first octet and a second octet; wherein the third type of bits are reserved bits of the first octet; and the first type of bits are reserved bits of the second octet.

[0197] It should be noted that the first MAC CE shown in the above embodiment can directly use the reserved bits in the existing MAC CE; specifically, the reserved bits in the first octet are used to carry the third type of bits, and the reserved bits in the second octet are used to carry the first type of bits. In this way, the reserved bits in the second octet of the existing MAC CE can be directly used without structural modification to the existing MAC CE to enable or disable CSI reporting at the sub-configuration granularity.

[0198] In some embodiments, the second octet further includes: at least one second type bit.

[0199] In some embodiments, at least one second type bit is used to indicate an activated or deactivated CSI reporting configuration.

[0200] The at least one first-category bit in the second octet is used to indicate activation or deactivation of a subconfiguration within the CSI reporting configuration activated by the second-category bit.

[0201] In some embodiments, the first octet is further used to indicate a serving cell identifier and / or a partial bandwidth BWP identifier.

[0202] In some embodiments, the first octet further includes at least one of the following:

[0203] The first information field carries the serving cell identifier;

[0204] The second information field carries the partial bandwidth BWP identifier.

[0205] It should be noted that the serving cell ID indicates the ID of the serving cell to which the first MAC CE applies; the length of the first information field may be 5 bits. The BWP ID indicates the ID of the uplink BWP applied by the first MAC CE. The length of the second information field may be 2 bits.

[0206] In some embodiments, the first octet of the first MAC CE may carry 1 third class bit; the second octet may carry 4 second class bits and 4 first class bits.

[0207] It is worth noting that when the bit value of the third type of bit is 1, it indicates that the MAC CE is the first MAC CE; when the bit value of the second type of bit is 0, it indicates that the MAC CE is the second MAC CE.

[0208] In some embodiments, the four first-category bits in the second octet indicate at least one of the following:

[0209] The four second-type bits in the second octet indicate activation or deactivation of sub-configurations within all activated CSI reporting configurations;

[0210] Refer to the activation or deactivation of sub-configuration within the CSI reporting configuration.

[0211] It should be noted that the reference CSI reporting configuration may be determined based on a predefined method. For example, the reference CSI reporting configuration may be the CSI reporting configuration corresponding to the minimum CSI configuration identifier in the CSI reporting configuration set.

[0212] In some embodiments, the size of the first MAC CE is 16 bits.

[0213] Optional embodiment 2:

[0214] In some embodiments, the first type of bits are reserved bits for the first MAC CE.

[0215] It should be noted that the disclosed embodiments directly utilize reserved bits within the existing MAC CE to carry the first type of bit to indicate the activation or deactivation of a sub-configuration. This allows activation or deactivation of CSI reporting at the sub-configuration granularity without structural modification to the existing MAC CE.

[0216] In some embodiments, the first MAC CE includes: a first octet and a second octet; wherein the first type of bits are reserved bits in the first octet and the second octet.

[0217] It is worth noting that the reserved bits in the first MAC CE of this embodiment are all used to carry the first type of bits. In other words, the first MAC CE does not include the third type of bits.

[0218] In order to distinguish the first MAC CE from the second MAC CE, in some embodiments, the header of the MAC PDU or the header of the MAC sub-PDU where the first MAC CE is located may include: an LCID field; the LCID field carries the LCID corresponding to the first MAC CE.

[0219] In other embodiments, the first MAC CE and the second MAC CE may be distinguished based on the bit value of the reserved bit in the MAC CE.

[0220] It should be noted that whether the reserved bits of the MAC CE are used to carry the first type of bits can be determined based on whether the bit values ​​of all reserved bits in the MAC CE are preset bit values; thereby determining whether the MAC CE is the first MAC CE.

[0221] Exemplarily, if the bit values ​​of all reserved bits in the MAC CE are 0, it indicates that the MAC CE is the second MAC CE.

[0222] In some embodiments, the second octet further includes: at least one second type bit.

[0223] In some embodiments, at least one second-class bit is used to indicate an activated or deactivated CSI reporting configuration; and at least one first-class bit within the second octet is used to indicate activation or deactivation of a subconfiguration within the activated CSI reporting configuration indicated by the second-class bit.

[0224] In some embodiments, the first octet is further used to indicate a serving cell identifier and / or a partial bandwidth BWP identifier.

[0225] In some embodiments, the first octet further includes at least one of the following:

[0226] The first information field carries the serving cell identifier;

[0227] The second information field carries the partial bandwidth BWP identifier.

[0228] It should be noted that the serving cell ID indicates the ID of the serving cell to which the first MAC CE applies; the length of the first information field may be 5 bits. The BWP ID indicates the ID of the uplink BWP applied by the first MAC CE. The length of the second information field may be 2 bits.

[0229] In some embodiments, the first octet of the first MAC CE may carry 1 first class bit; the second octet may carry 4 second class bits and 4 first class bits.

[0230] In some embodiments, the four first-category bits in the second octet indicate at least one of the following:

[0231] The four second-type bits in the second octet indicate activation or deactivation of sub-configurations within all activated CSI reporting configurations;

[0232] Refer to the activation or deactivation of sub-configuration within the CSI reporting configuration.

[0233] It should be noted that the reference CSI reporting configuration may be determined based on a predefined method. For example, the reference CSI reporting configuration may be the CSI reporting configuration corresponding to the minimum CSI configuration identifier in the CSI reporting configuration set.

[0234] In some embodiments, the size of the first MAC CE is 16 bits.

[0235] Optional embodiment three:

[0236] In some embodiments, the first type of bits and the second type of bits are located in different octets of the first MAC CE; wherein, the first type of bits carried by one of the octets are used to indicate the activation or deactivation of a sub-configuration of the CSI reporting configuration indicated by one of the second type of bits.

[0237] It should be noted that, on the basis of the existing MAC CE, the first MAC CE of this embodiment adds at least one octet for carrying first-class bits; and utilizes the first-class bits carried by an octet to correspond to a CSI report configuration indicated by a second-class bit to indicate the activation or deactivation of the sub-configuration within the corresponding CSI report configuration.

[0238] In some embodiments, the bits of the first MAC CE constitute N octets: N is a positive integer greater than or equal to 3;

[0239] The first octet of the first MAC CE is used to indicate at least a serving cell identifier and / or a partial bandwidth BWP identifier;

[0240] The second type of bits are located in the second octet of the first MAC CE;

[0241] The first type of bits are located in the nth octet of the first MAC CE; wherein n is a positive integer greater than or equal to 3 and less than or equal to N.

[0243] In some embodiments, the identifier corresponding to the CSI reporting configuration mapped from the 3rd octet to the Nth octet of the first MAC CE increases gradually.

[0244] It can be understood that the first type of bits in the third octet are used to activate or deactivate multiple sub-configurations within the CSI reporting configuration indicated by the second type of bits corresponding to the minimum CSI configuration identifier. The first type of bits in the Nth octet are used to activate or deactivate multiple sub-configurations within the CSI reporting configuration indicated by the second type of bits corresponding to the maximum CSI configuration identifier.

[0245] In some other embodiments, the identifiers corresponding to the CSI reporting configurations mapped from the 3rd octet to the Nth octet of the first MAC CE are gradually reduced.

[0248] or,

[0249] The first type of bits in an octet corresponds to multiple sub-configurations in a CSI report configuration in a CSI report configuration set.

[0250] It is worth noting that the number of newly added octets in the first MAC CE can be determined based on the number of activated CSI reporting configurations indicated by the second type of bits in the second octet. It is understood that for each activated CSI reporting configuration, there is a corresponding octet carrying the first type of bits; the first type of bits in an octet are used to indicate the activation or deactivation of a sub-configuration within the corresponding activated CSI reporting configuration.

[0251] Alternatively, the number of newly added octets within the first MAC CE may be determined based on the number of CSI reporting configurations included in the CSI reporting configuration set. It is understood that for each CSI reporting configuration within the CSI reporting configuration set, there is a corresponding octet carrying a first-class bit; that is, for an inactivated CSI reporting configuration, there is also a corresponding octet carrying a first-class bit. The first-class bit within an octet is used to indicate the activation or deactivation of a sub-configuration within the corresponding CSI reporting configuration.

[0252] In some embodiments, the first octet further includes at least one of the following:

[0256] In some embodiments, the first MAC CE may be a MAC CE of variable size.

[0257] In some embodiments, the size of the first MAC CE is N*8 bits.

[0258] It can be understood that the size of the first MAC CE in this embodiment can be determined by the number of octets included in the first MAC CE.

[0259] Optional embodiment four:

[0260] In some embodiments, the first MAC CE includes M octets; wherein M is a positive integer greater than or equal to 2;

[0261] The first type of bits are located in the mth octet of the first MAC CE; wherein m is greater than or equal to 2 and less than or equal to M;

[0262] The first type of bits in one of the octets are used to indicate activation or deactivation of a sub-configuration in the CSI reporting configuration.

[0263] It should be noted that, compared with the first MAC CE shown in optional embodiment three, the first MAC CE in the embodiment of the present disclosure does not include an octet carrying second-type bits; that is, the first MAC CE in the embodiment of the present disclosure does not carry second-type bits.

[0264] In some embodiments, the identifier corresponding to the CSI reporting configuration mapped from the 2nd octet to the Mth octet of the first MAC CE of the embodiment of the present disclosure gradually increases.

[0265] It can be understood that the first type of bits in the second octet are used to activate or deactivate multiple sub-configurations in the CSI reporting configuration corresponding to the minimum CSI configuration identifier in the CSI reporting configuration set. The first type of bits in the Mth octet are used to activate or deactivate multiple sub-configurations in the CSI reporting configuration corresponding to the maximum CSI configuration identifier in the CSI reporting configuration set.

[0266] In some embodiments, the identifiers corresponding to the CSI reporting configurations mapped from the 2nd octet to the Mth octet of the first MAC CE gradually decrease.

The first type of bits in the Mth octet are used to activate or deactivate multiple sub-configurations in the CSI reporting configuration corresponding to the minimum CSI configuration identifier in the CSI reporting configuration set.

[0268] In some embodiments, the first octet in the first MAC CE may indicate at least a serving cell identifier and / or a partial bandwidth BWP identifier.

[0269] In some embodiments, the first octet further includes at least one of the following:

[0270] The first information field carries the serving cell identifier;

[0271] The second information field carries the partial bandwidth BWP identifier.

[0272] It should be noted that the serving cell ID indicates the ID of the serving cell to which the first MAC CE applies; the length of the first information field may be 5 bits. The BWP ID indicates the ID of the uplink BWP applied by the first MAC CE. The length of the second information field may be 2 bits.

[0273] In some embodiments, the third type of bits are reserved bits of the first octet.

[0274] It can be understood that the first MAC CE and the second MAC CE are distinguished directly by using different bit values ​​of the third type of bits.

[0275] In some embodiments, the first MAC CE may be a MAC CE of variable size.

[0276] In some embodiments, the size of the first MAC CE is M*8 bits.

[0277] It can be understood that the size of the first MAC CE can be determined by the number of octets included in the first MAC CE.

[0278] In some embodiments, such a first MAC CE may not include the second type of bits.

[0279] Optional embodiment five:

[0280] In some embodiments, one of the second-category bits is used to indicate activation or deactivation of one of the CSI reporting configurations;

[0281] An octet of the first MAC CE includes at least one first-category bit and one second-category bit; wherein,

[0282] The first-category bit adjacent to the nth second-category bit and located in the same octet is used to indicate the activation or deactivation of the sub-configuration in the CSI report configuration corresponding to the nth second-category bit.

[0283] It should be noted that the first MAC CE shown in the embodiment of the present disclosure can carry the first type of bits and the second type of bits in the same octet, and use the first type of bits adjacent to the second type of bits in the same octet to indicate that the second type of bits indicate the activation or deactivation of the sub-configuration within the activated CSI reporting configuration.

[0284] In some embodiments, one of the octets includes two bits of the second type;

[0285] The two second-category bits in one octet are spaced apart, and one second-category bit corresponds to X first-category bits; X is a positive integer greater than or equal to 1 and less than or equal to 3.

[0286] It can be understood that the two second-class bits within an octet respectively indicate the activation or deactivation of different CSI reporting configurations; the first-class bit adjacent to a second-class bit in the same octet is used to indicate the activation or deactivation of a sub-configuration within an activated CSI reporting configuration indicated by the adjacent second-class bit; and the first-class bit adjacent to another second-class bit in the same octet is used to indicate the activation or deactivation of a sub-configuration within an activated CSI reporting configuration indicated by the adjacent second-class bit.

[0287] In some embodiments, one of the octets includes two bits of the second type;

[0288] The two second-category bits in one octet are spaced apart, and one second-category bit corresponds to three first-category bits.

[0289] In some embodiments, the first octet in the first MAC CE may indicate at least a serving cell identifier and / or a partial bandwidth BWP identifier.

[0290] In some embodiments, the first octet further includes at least one of the following:

[0291] The first information field carries the serving cell identifier;

[0292] The second information field carries the partial bandwidth BWP identifier.

[0293] It should be noted that the serving cell ID indicates the ID of the serving cell to which the first MAC CE applies; the length of the first information field may be 5 bits. The BWP ID indicates the ID of the uplink BWP applied by the first MAC CE. The length of the second information field may be 2 bits.

[0294] In some embodiments, the third type of bits are reserved bits of the first octet.

[0295] It can be understood that the first MAC CE and the second MAC CE are distinguished directly by using different bit values ​​of the third type of bits.

[0296] In some embodiments, the first MAC CE may be a MAC CE of variable size.

[0297] In some embodiments, the size of the first MAC CE is M*8 bits.

[0298] It can be understood that the size of the first MAC CE can be determined by the number of octets included in the first MAC CE.

[0299] In some embodiments, the network device may determine the format of the first MAC CE sent to the terminal based on protocol agreement.

[0300] In some embodiments, the network device may send second information to the terminal, where the second information indicates the format of the first MAC CE.

[0301] It is understandable that the network device can independently determine the format of the first MAC CE sent to the terminal, and inform the terminal through the second information so that the terminal can decode it.

[0302] In some embodiments, the terminal may send third information to the network device, where the third information indicates the format of the first MAC CE.

[0303] It is understandable that the terminal may send third information to the network device to inform the network device of the format of the first MAC CE that the terminal expects to use; the network device may determine the format of the first MAC CE based on the third information.

[0304] It is worth noting that the format of the first MAC CE finally determined by the network device may be the same as or different from the format of the first MAC CE that the terminal expects to use. In order to achieve information alignment, the network device may send second information to the terminal after determining the format of the first MAC CE.

[0305] Step S2102: The terminal determines activation or deactivation of a sub-configuration within the CSI reporting configuration.

[0306] In some embodiments, the terminal determines activation or deactivation of a sub-configuration within the CSI reporting configuration based on a received MAC CE.

[0307] In some embodiments, the terminal determines activation or deactivation of a sub-configuration within the CSI reporting configuration according to the received first MAC CE.

[0308] In some embodiments, the terminal may determine whether the received MAC CE is the first MAC CE based on the third type of bits in the MAC CE.

[0309] It can be understood that since different bit values ​​of the third type of bits can be used to distinguish the first MAC CE from the second MAC CE, the terminal can decode the received MAC CE and determine whether the received MAC CE is the first MAC CE or the second MAC CE based on the bit value of the third type of bits carried in the MAC CE.

[0310] In some embodiments, the terminal may determine whether the received MAC CE is the first MAC CE based on the LCID carried in the header of the MAC PDU where the MAC CE is located or the header of the MAC sub-PDU.

[0311] It should be noted that, since the LCID of the first MAC CE is different from the LCID of the second MAC CE, the terminal can obtain the LCID carried in the header of the MAC PDU or the header of the MAC sub-PDU where the MAC CE is located to determine whether the received MAC CE is the first MAC CE.

[0312] In some embodiments, the terminal may determine activation or deactivation of a sub-configuration of the CSI reporting configuration based on the first type of bits in the first MAC CE.

[0313] In some embodiments, the first type of bits indicates that the activated sub-configuration identifier exceeds the identifier range of the sub-configuration included in the CSI report configuration, and the terminal may ignore the first type of bits.

[0314] In some embodiments, the terminal may determine the activated or deactivated CSI reporting configuration based on the second type of bits in the first MAC CE; and determine the activation or deactivation of the sub-configuration in the activated CSI reporting configuration based on at least one first type of bit.

[0315] In some embodiments, the terminal determines the format of the received first MAC CE.

[0316] It should be noted that the first MAC CE may have different optional formats, and the decoding information of the first MAC CEs of different formats may indicate different contents. Therefore, the terminal needs to first determine the format of the received first MAC CE.

[0317] In some embodiments, the terminal may determine the format of the first MAC CE according to a protocol agreement.

[0318] In some embodiments, the terminal may determine the format of the first MAC CE based on the second information sent by the network device.

[0319] A first optional format for the first MAC CE.

[0320] In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on a reserved bit in the first octet of the MAC CE.

[0322] In some embodiments, the terminal may determine the activated CSI reporting configuration based on the second type of bits of the second octet in the first MAC CE; and determine the activation or deactivation of the sub-configuration within the activated CSI reporting configuration based on the reserved bits of the second octet in the first MAC CE.

[0323] It should be noted that the first MAC CE of the first optional format can indicate to the terminal the activation or deactivation of the sub-configuration within the activated CSI reporting configuration without changing the existing MAC CE format.

[0324] A second optional format for the first MAC CE.

[0325] In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on the LCID carried in the header of the MAC PDU or the header of the MAC sub-PDU where the MAC CE is located.

[0326] In some embodiments, the terminal may determine activation or deactivation of a sub-configuration within the CSI reporting configuration based on all reserved bits within the first MAC CE.

[0327] In some embodiments, the terminal may determine the activated CSI reporting configuration based on the second type of bits of the second octet in the first MAC CE; and determine the activation or deactivation of the sub-configuration within the activated CSI reporting configuration based on all reserved bits in the first MAC CE.

[0328] It should be noted that the first MAC CE of the second optional format can indicate to the terminal the activation or deactivation of the sub-configuration within the activated CSI reporting configuration without changing the existing MAC CE format.

[0329] A third optional format for the first MAC CE.

[0330] In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on a reserved bit in the first octet of the MAC CE.

[0331] In some embodiments, the terminal may determine the identifier corresponding to the activated CSI reporting configuration based on the second type of bits of the second octet in the first MAC CE; determine the corresponding octet based on the identifier corresponding to the activated CSI reporting configuration; and determine the activation or deactivation of the sub-configuration within the activated CSI reporting configuration based on the first type of bits in the corresponding octet.

[0332] It should be noted that the first MAC CE in the third optional format can not only indicate to the terminal the activation or deactivation of the sub-configuration within the activated CSI reporting configuration, but also reduce the decoding amount of the terminal.

[0333] A fourth optional format for the first MAC CE.

[0334] In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on a reserved bit in the first octet of the MAC CE.

[0335] In some embodiments, the terminal may determine activation or deactivation of a sub-configuration within the CSI reporting configuration corresponding to the mth octet based on the first type of bits within the mth octet within the first MAC CE.

[0336] It should be noted that the first MAC CE of the fourth optional format, without carrying the second type of bits, may be able to indicate to the terminal the activated CSI reporting configuration and the activation or deactivation of the sub-configuration within the activated CSI reporting configuration.

[0337] A fourth optional format for the first MAC CE.

[0338] In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on a reserved bit in the first octet of the MAC CE.

[0339] In some embodiments, the terminal may determine the activated CSI reporting configuration based on the second type of bits in an octet; and determine the activation or deactivation of the sub-configuration within the activated CSI reporting configuration based on the first type of bits adjacent to the second type of bits indicating the activated CSI reporting configuration in the same octet.

[0340] It should be noted that the first MAC CE of the fifth optional format can not only indicate to the terminal the activation or deactivation of the sub-configuration within the activated CSI reporting configuration, but also reduce the decoding amount of the terminal.

[0341] In some embodiments, the terminal may perform corresponding measurements based on the activated sub-configuration within the CSI reporting configuration.

[0342] It should be noted that the sub-configuration of the CSI report configuration corresponds to the spatial pattern (SD) element and / or the transmit power consumption. Compared with the way in which the terminal performs measurements based on the CSI report configuration, in the embodiment of the present disclosure, the terminal only performs measurements related to the sub-configuration in which the CSI report configuration is partially activated, which can effectively reduce the measurement power consumption of the terminal.

[0343] Furthermore, the number of measurement results obtained by the terminal based on the measurements related to the sub-configurations activated in the CSI reporting configuration part will be reduced accordingly, thereby reducing the resources required for CSI reporting.

[0344] In some embodiments, the terminal may receive a second MAC CE sent by the network device.

[0345] In some embodiments, the terminal determines to activate or deactivate CSI configuration reporting based on the second MAC CE.

For example, step S3101 may be implemented as an independent embodiment, and step S2103 may be implemented as an independent embodiment, but is not limited thereto.

[0347] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that when the network device sends the second MAC CE, since the second MAC CE can only indicate activation of the CSI reporting configuration, the terminal does not need to activate or deactivate the sub-configuration within the CSI reporting configuration.

[0432] FIG5 is an interactive diagram illustrating a method for configuring and processing a channel state information (CSI) report according to an exemplary embodiment. As shown in FIG5 , an embodiment of the present disclosure relates to a method for configuring and processing a channel state information (CSI) report for a terminal in a non-connected state, the method comprising:

[0433] Step S5101: The network device sends a media access control MAC element CE to the terminal.

[0434] In some embodiments, the MAC CE includes a first MAC CE; the first MAC CE carries first information.

[0435] In some embodiments, the first information is used to indicate activation or deactivation of a sub-configuration of the CSI reporting configuration.

[0436] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc. embodiments, which will not be repeated here.

[0437] In the Rel-18 NES scenario, in order to reduce the power overhead of network devices, network devices can dynamically reduce the number of spatial elements (spatial elements) or transmission power corresponding to downlink data transmission based on the dynamic changes in the transmission load, thereby reducing network energy overhead. Taking into account the spatial adaptation (SD) mode of dynamic adjustment of the spatial elements or transmission power, Rel-18 defines CSI reporting with sub-configuration as the granularity. For the same CSI report config, it can contain L sub-configurations, each sub-configuration is associated with a specific spatial pattern (SD) and / or multiple power consumption (power) standards.

[0438] To improve terminal reporting efficiency and reduce corresponding reporting overhead, the base station can activate / deactivate reporting for N of the configured L sub-configurations through relevant signaling. For SP-type CSI reporting, activation / deactivation can be performed through MAC CE. However, in the existing mechanism, the MAC CE only activates / deactivates reporting at the granularity of the CSI report config. After the introduction of sub-configuration granularity reporting, how to activate / deactivate reporting for N sub-configurations within the L sub-configurations is still under further discussion.

[0439] The technical problem solved by the embodiments of the present disclosure, that is, the core idea of ​​the present invention, as described in the background, is to design a reporting sub-configuration (sub-configuration) with signaling indication activation / deactivation under the condition that a CSI report config contains multiple reporting sub-configurations, thereby improving the efficiency and accuracy of CSI measurement reporting and achieving consistent understanding between the terminal and the base station.

[0440] Under the condition that a CSI report config includes multiple reporting sub-configurations, the terminal receives the indication signaling, determines the activated reporting sub-configuration, and performs the corresponding CSI reporting.

[0441] Recultivate the reserved bit (such as R) field of the existing MAC CE, or introduce a new field, such as Ni; indicate the activation / deactivation status of the corresponding sub-configuration in a bitmap manner.

[0442] N0 corresponds to the sub-configuration ID or the sub-configuration with the smallest position index in the CSI report configuration; Ni corresponds to the sub-configuration ID or the sub-configuration with the (i+1)th smallest position index in the CSI report configuration.

[0443] When Ni is 0, it indicates that the corresponding sub-configuration is deactivated; when Ni is 1, it indicates that the corresponding sub-configuration is activated;

[0444] If the MAC CE is enhanced based on the existing MAC CE, the terminal determines the indication function of the MAC CE based on the R field of Oct 1. That is, if the indication is 0, it is a legacy MAC CE, indicating the activation / deactivation of the CSI report configuration; if the indication is 1, the MAC CE indicates the activation / deactivation of the CSI report sub-configuration.

[0445] If the fixed size of the MAC CE is N bits, N is greater than or equal to 16, or corresponds to a variable size.

[0446] Under the condition that a CSI report configuration includes multiple reporting sub-configurations, the base station determines an activated reporting sub-configuration, transmits corresponding indication signaling, and receives corresponding CSI reporting results.

[0447] The reserved bit (eg, R) field of the existing MAC CE is re-cultivated, or a new field (eg, Ni) is introduced to indicate the activation / deactivation status of the corresponding sub-configuration in a bitmap manner.

[0448] N0 corresponds to the sub-configuration ID or the sub-configuration with the smallest position index in the CSI report configuration; Ni corresponds to the sub-configuration ID or the sub-configuration with the (i+1)th smallest position index in the CSI report configuration.

[0449] When Ni is 0, it indicates that the corresponding sub-configuration is deactivated; when Ni is 1, it indicates that the corresponding sub-configuration is activated.

[0450] If the MAC CE is enhanced based on the existing MAC CE, the terminal determines the indication function of the MAC CE based on the R field of Oct 1. That is, if the indication is 0, it is a legacy MAC CE, indicating the activation / deactivation of the CSI report configuration; if the indication is 1, the MAC CE indicates the activation / deactivation of the CSI report sub-configuration.

[0451] If the MAC CE has a fixed size of N bits, N is greater than or equal to 16, or corresponds to a variable size.

[0452] The following describes the specific implementation of the present invention from the perspectives of a terminal and a base station:

[0453] Assume that the terminal supports the NES feature. To support measurement reporting for multiple spatial patterns (SDs) and / or multiple power standards, NES supports sub-CSI reporting for multiple sub-configurations defined for the same CSI report configuration. Compared to the existing mechanism where one CSI report configuration corresponds to one CSI, Rel-18 NES corresponds to one CSI report configuration for multiple sub-configurations, with each sub-configuration corresponding to a sub-CSI report, effectively improving dynamic CSI measurement and reporting performance.

[0454] Under the condition of configuring multiple sub-configurations, the embodiment of the present disclosure mainly designs corresponding MAC CE indication signaling based on the existing MAC CE (the existing MAC CE is described in the background) to indicate the activation / deactivation of the corresponding sub-configuration. The specific indication method is as follows:

[0455] Implementation 1: Refarming an existing reserved bit, such as "R", to indicate the activation status of the corresponding sub-configuration. It should be noted that the MAC CE indication signaling shown in Implementation 1 may correspond to the MAC CE of the first format and / or the second format of the present disclosure.

[0456] As shown in Figures 6A and 6B, Figure 6A is a schematic diagram of the structure of a MAC CE in a first format according to an exemplary embodiment. Figure 6B is a schematic diagram of the structure of a MAC CE in a second format according to an exemplary embodiment.
