[0106] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0107] In the embodiments of the present disclosure, unless otherwise specified, elements expressed in the singular form, such as "a", "an", "a kind of", "the", "above", "said", "aforementioned", "this", etc., may mean "one and only one", or "one or more", "at least one", etc. For example, when articles such as "a", "an", "the" in English are used in translation, the noun after the article may be understood as a singular expression or a plural expression.

[0108] In the embodiments of the present disclosure, “plurality” refers to two or more than two.

[0109] In some embodiments, the terms "at least one", "one or more", etc. can be used interchangeably.

The statement of the description object refers to the description in the context of the claims or embodiments, and should not constitute unnecessary restrictions due to the use of prefixes. For example, if the description object is a "field", the ordinal number before the "field" in the "first field" and the "second field" does not limit the position or order between the "fields", and the "first" and "second" do not limit whether the "fields" they modify are in the same message, nor do they limit the order of the "first field" and the "second field". For another example, if the description object is a "level", the ordinal number before the "level" in the "first level" and the "second level" does not limit the priority between the "levels". For another example, the number of description objects is not limited by the ordinal number, and can be one or more. Taking the "first device" as an example, the number of "devices" can be one or more. In addition, the objects modified by different prefixes may be the same or different. For example, if the description object is "device", then the "first device" and the "second device" may be the same device or different devices, and their types may be the same or different.

[0274] Hereinafter, the embodiments of the present disclosure are exemplarily described through specific implementation modes.

[0275] In some embodiments, the terminal adopts a mechanism for reporting cache status according to the data category of the data.

[0276] In some embodiments, the data category may be an importance level, or other categories classified according to QoS requirements, such as reliability requirements. In this way, data with a specific category can be sent in a timely manner, which improves communication efficiency and user experience. This article takes importance levels as an example.

[0277] In some embodiments, the cache status report (ie, the first information) includes a BSR report and a DSR report.

[0278] In some embodiments, the importance level (ie, importance grade) may be subdivided into different levels, such as 0 to 15 levels.

[0279] In some embodiments, the importance level may be divided into two categories, such as important and not important.

[0280] In some embodiments, the terminal evaluates whether it is important or not important based on the terminal implementation.

[0281] In some embodiments, the terminal reports the data volume of data of one or more specified data categories in the BSR or DSR.

[0282] In some embodiments, the reported value of the amount of data reported by the terminal may be 0, which means that there is no amount of data of the specified data importance level.

[0283] In some embodiments, the reported value of the data volume reported by the terminal may be 0, which means that there is no data volume of this data category.

[0284] In some embodiments, the terminal may carry a data importance indication field in the BSR or DSR to distinguish the importance level of the cache size of the data.

[0285] In some embodiments, the terminal may carry a data category indication field in the BSR or DSR to distinguish the cache size of the data, so as to inform the base station of which data category the data is reported.

[0286] Fig. 7A FIG. 1 is a schematic diagram of an exemplary implementation of a MAC CE provided according to an embodiment of the present disclosure. Fig. 7A In the example, I=1 means the importance level is high; I=0 means the importance level is low.

[0287] Figure 7B FIG. 1 is a schematic diagram of an exemplary implementation of a MAC CE provided according to an embodiment of the present disclosure. Figure 7B In the DSR MAC CE, the R field is used to indicate the data importance level: R = 1 means the importance level is high; R = 0 means the importance level is low. It should be noted that the R field is only used when packet discard based on packet data unit (PDU) set importance (PSI) is not activated.

[0288] In some embodiments, the terminal may use different reserved LCHIDs to indicate that the BSR MAC CE or DSR MAC CE is used to carry data of a specified importance level.

[0289] In some embodiments, LCHID=x indicates a BSR MAC CE or DSR MAC CE reported for data with a high importance level; LCHID=y indicates a BSR MAC CE or DSR MAC CE reported for the cache size of data with a low importance level; and LCHID=z indicates a BSR MAC CE or DSR MAC CE reported for the cache size of all data.

[0290] In some embodiments, the base station may instruct (ie, the second information) the terminal to report the amount of data of a specified category.

[0291] In some embodiments, the base station instructs the terminal whether to report the cache status of data with a high importance level, the cache status of data with a low importance level, or the cache size of all data to be transmitted.

[0292] In some embodiments, the base station may configure or indicate for each LCG.

[0293] In some embodiments, the indication signaling may be based on RRC signaling or MAC CE, etc.

[0294] In some embodiments, the terminal may simultaneously report the data volume of data of at least one data category.

[0295] In some embodiments, the terminal may report the data volume of at least one data category simultaneously.

[0296] In some embodiments, for an LCG, the terminal may simultaneously report the data volume of at least one data category.

[0297] In some embodiments, for one LCG, the terminal may simultaneously report the amount of data of at least one data importance level.

[0298] In some embodiments, multiple fields are reported from high to low priority (eg, sorted by importance level) to indicate the amount of data of different data importances. If there is no data for the remaining priorities, the next LCG is reported.

[0299] In some embodiments, an indication field may be set to indicate whether the LCG has more data to report.

[0300] In some embodiments, for an LCG, the data with the highest priority level is reported first. If the indication field is 1, it means that the LCG will report data with a lower priority level.

[0301] In some embodiments, if the indication field is 0, it means that the data of the LCG has been reported and the next LCG report will be reported.

[0302] In some embodiments, the amount of data of a specified data importance level reported by the terminal in the BSR or DSR may be reported together with the total amount of data.

[0303] In some embodiments, a percentage may be reported, indicating the amount of data having a specified data importance level in the total amount of data.

[0304] In some embodiments, new terminal capabilities are introduced to support the capability of the mechanism for reporting cache status according to the data category of the data.

[0305] In some embodiments, new terminal capabilities are introduced to support the capability of the mechanism for reporting cache status according to the importance of data.

[0306] In the embodiments of the present disclosure, part or all of the steps and their optional implementations may be arbitrarily combined with part or all of the steps in other embodiments, or may be arbitrarily combined with optional implementations of other embodiments.
