    "1. A wireless communication method, performed by a user equipment (UE) in a network, the method comprising: transmitting a signaling for requesting uplink resources, wherein the signaling carries information for indicating buffer size information or traffic type or Buffer Status Report (BSR) table type information or resource requesting information; and transmitting data on the requested uplink resources scheduled based on the indicated buffer size information or traffic type or BSR table type information. 2. The method of claim 1, wherein the signaling is a scheduling request (SR), and the SR carries zero or one or more bits for indicating the buffer size information or the traffic type or the BSR table type information. 3. The method of claim 2, wherein a state represented by the zero or one or more bits of the SR indicates a range or an upper limit value of the buffer size information. 4. The method of claim 2, wherein a state represented by the one or more bits of the SR indicates that indicates resources for BSR is required to be scheduled. 5. (canceled) 6. The method of claim 2, wherein the SR can be transmitted on different time and/or frequency resources, wherein the time and/or frequency resources of the SR indicate different BSR size or traffic type or BSR table type. 7. The method of claim 2, wherein when a transmission occasion of the SR is overlapped in time domain with Uplink Control Information (UCI) in a resource using a same Physical Uplink Control Channel (PUCCH) format, a priority rule is used to determine which one of the SR and the UCI is to be transmitted if the SR is a positive SR that requests resources for data transmission. 8. The method of claim 7, wherein which one of the SR and the UCI is transmitted is based on the priorities of the SR and the UCI, and a cyclic shift parameter used for the transmission is determined based on the one having a high priority. 9. The method of claim 7, wherein the UCI is transmitted using the PUCCH format for the UCI and a cyclic shift parameter used for the transmission is determined based on the SR. 10. The method of claim 7, wherein the UCI is transmitted using the PUCCH format for the SR and a cyclic shift parameter used for the transmission is determined based on the UCI. 11. The method of claim 2, wherein when a transmission occasion of the SR is overlapped in time domain with UCI in a resource using a same PUCCH format, the UCI and the SR are combined and then transmitted using the PUCCH format, and each sequence from the combination of the UCI and the SR relates to a cyclic shift value. 12. The method of claim 2, wherein when a transmission occasion of the SR is overlapped in time domain with UCI in a resource using a same PUCCH format, which one of the SR and the UCI is transmitted is based on which has an early symbol in the PUCCH format. 13. The method of claim 2, wherein when a transmission occasion of the SR is overlapped in time domain with UCI in a resource using a same PUCCH format, the UCI is transmitted using the PUCCH format, and a cyclic shift parameter used for the transmission is determined based on a parameter different from the UCI. 14. (canceled) 15. The method of claim 2, wherein when a transmission occasion of the SR in a resource using a first PUCCH format is overlapped in time domain with UCI in a resource using a second PUCCH format, a PUCCH with the UCI in the resource using the second PUCCH format is transmitted if the SR is a negative SR; and a PUCCH with the SR in the resource using the first PUCCH format is transmitted if the SR is a positive SR. 16. The method of claim 2, wherein when a transmission occasion of the SR in a resource using a first PUCCH format is overlapped in time domain with UCI in a resource using a second PUCCH format, which one of the SR and the UCI is transmitted is based on which has an early symbol in a corresponding PUCCH format. 17. The method of claim 2, wherein when a transmission occasion of the SR in a resource using a first PUCCH format is overlapped in time domain with UCI in a resource using a second PUCCH format, the UCI and the SR are combined and then transmitted using the first PUCCH format or the second PUCCH format. 18. The method of claim 2, wherein when a transmission occasion of the SR in a resource using a PUCCH format is overlapped in time domain with UCI in a resource using the same PUCCH format, a PUCCH with the UCI in the resource using the PUCCH format for the UCI is transmitted if the SR is a negative SR; and a PUCCH with the SR in the resource using the PUCCH format for the SR is transmitted if the SR is a positive SR. 19. (canceled) 20. The method of claim 2, wherein when a transmission occasion of the SR in a resource using a PUCCH format is overlapped in time domain with UCI in a resource using the same PUCCH format, which one of the SR and the UCI is transmitted is based on length of the SR and UCI in the PUCCH format if a start symbol of the SR and UCI is the same. 21 - 26. (canceled) 27. The method of claim 1, further comprising: receiving a Media Access Control (MAC) Control Element (CE) with a field indicating a type of BSR table that the buffer size information is referred to. 28. A wireless communication method, performed by a base station (BS) in a network, the method comprising: receiving a signaling used to request uplink resources, wherein the signaling carries information for indicating buffer size information or traffic type or Buffer Status Report (BSR) table type information or resource requesting information; and receiving data transmitted on the requested uplink resources scheduled based on the indicated buffer size information or traffic type or BSR table type information. 29 - 53. (canceled) 54. The method of claim 28, further comprising: transmitting a Media Access Control (MAC) Control Element (CE) with a field indicating a type of BSR table that the buffer size information is referred to. 55. A user equipment (UE), comprising a processor and a transmitter, wherein the processor is configured to call and run program instructions stored in a memory, to cooperate with the transmitter to execute operations comprising: transmitting a signaling for requesting uplink resources, wherein the signaling carries information for indicating buffer size information or traffic type or Buffer Status Report (BSR) table type information or resource requesting information; and transmitting data on the requested uplink resources scheduled based on the indicated buffer size information or traffic type or BSR table type information. 56.

  "description_excerpt": "The present application relates to wireless communication technologies, and more particularly, to a wireless communication method, and related devices such as a user equipment (UE) and a base station (BS) (e.g., a gNB).\n\nWireless communication systems, such as the third-generation (3G) of mobile telephone standards and technology are well known. Such 3G standards and technology have been developed by the Third Generation Partnership Project (3GPP). The 3rd generation of wireless communications has generally been developed to support macro-cell mobile phone communications. Communication systems and networks have developed towards being a broadband and mobile system. In cellular wireless communication systems, user equipment (UE) is connected by a wireless link to a radio access network (RAN). The RAN includes a set of base stations (BSs) which provide wireless links to the UEs located in cells covered by the base stations, and an interface to a core network (CN) which provides overall network control. The RAN and CN each conducts respective functions in relation to the overall network.\n\nThe 3GPP has developed the so-called Long-Term Evolution (LTE) system, namely, an Evolved Universal Mobile Telecommunication System Territorial Radio Access Network (E-UTRAN), for a mobile access network where one or more macro-cells are supported by base station knowns as an eNodeB or eNB (evolved NodeB). More recently, LTE is evolving further towards the so-called 5G or NR (new radio) systems where one or more cells are supported by base stations known as a next generation Node B called gNodeB (gNB).",
