Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the invention without undue burden, are within the scope of the invention.
The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

In LTE or NR, if the base station has an uplink scheduling request for the terminal device, but the terminal device does not have any data to transmit at this time, the terminal device can only fill the physical layer resource block with invalid data, and then send the invalid data to the base station. For example, in the case that the terminal device has no data to be transmitted, the data transmitted to the base station is shown in table 1 below:
TABLE 1
In table 1, SFN is a system frame number, sub-FN is a subframe number, grant bytes is an uplink scheduling resource size, and padding bytes is filled invalid data. It can be seen that the base station issues a request for uplink resource scheduling to the terminal device for a long time, but the radio link control (radio link control, RLC) layer of the terminal device does not have any protocol data unit (protocol data unit, PDU) to be transmitted, RLC PDUs is 0 in table 1, the header of the removed medium access control (media access control, MAC) layer occupies 5 bytes, the header of the MAC layer is "MAC hdr+ce" in table 1, and "all other data is padding bytes". For example, the subframe 4 uplink scheduling data (Grant bytes) in the 648 system frame is 173, the mac layer header occupies 5 bytes, and there is no RLC packet (RLC PDUS is 0), so that the padding bytes (called padding data) is 173-5=168. As can be seen from table 1, the base station schedules the uplink resources of the terminal device for a plurality of times for a long time, but the terminal device does not need to transmit data, and the transmission is invalid data, so that the power consumption of the terminal device is necessarily increased.
The embodiment of the invention provides an uplink scheduling indication method, terminal equipment and network equipment, wherein the terminal equipment receives uplink scheduling data requests sent by the network equipment on N continuous subframes; the uplink scheduling data request is used for scheduling uplink resources, and N is an integer greater than or equal to 1; if the terminal equipment does not have data to be transmitted in the N subframes, sending an uplink scheduling indication for indicating that the terminal equipment does not have the data to be transmitted to the network equipment, and receiving the uplink scheduling indication sent by the terminal equipment and used for indicating that the terminal equipment does not have the data to be transmitted by the network equipment. According to the scheme, the network equipment can know that the terminal equipment does not have data and can send the data according to the uplink scheduling indication, so that uplink resources can be not scheduled any more, namely uplink scheduling data requests are not sent to the terminal equipment any more, the situation that the terminal equipment sends invalid data to the base station through filling when the terminal equipment does not have data to be sent can be avoided, and power consumption of the terminal equipment is increased.
The uplink scheduling indication method provided by the embodiment of the invention can be realized based on a wireless communication system. Fig. 1 is a schematic diagram of a wireless communication system. In fig. 1, a terminal device receives uplink scheduling data requests sent by a network device for scheduling uplink resources on N consecutive subframes, and the terminal device does not have data to be transmitted in the N subframes, so that the terminal device may send an uplink scheduling indication for indicating that the terminal device does not have data to be transmitted to the network device, and after receiving the uplink scheduling indication, the network device may not send the uplink scheduling data requests for scheduling uplink resources to the terminal device any more, thereby avoiding that the terminal device sends invalid data to a base station by filling when the terminal device does not have data to be transmitted, and increasing power consumption of the terminal device.
The network device in the embodiment of the present invention may be an LTE system, an NR communication system, or an evolved node b (evolutional node B, abbreviated as eNB or e-NodeB) macro base station, a micro base station (also called "small base station"), a pico base station, an Access Point (AP), a transmission station (transmission point, TP), a new generation base station (new generation Node B, gmodeb), or the like in an licensed assisted long term evolution (LAA-LTE) system. The network device may also be a future 5G communication system or other type of network device in a future evolution network.
The terminal device in the embodiment of the present invention may be referred to as a User Equipment (UE). The terminal device may be a personal communication service (personal communication service, PCS) phone, cordless phone, session initiation protocol (session initiation protocol, SIP) phone, wireless local loop (wireless local loop, WLL) station, personal digital assistant (personal digital assistant, PDA) or the like, or a handset, mobile Station (MS), mobile terminal (mobile terminal), laptop or the like, which may communicate with one or more core networks via a radio access network (radio access network, RAN). For example, the terminal device may be a mobile telephone (or "cellular" telephone) or a computer with a mobile terminal, etc., e.g., a portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile device that exchanges voice and/or data with the radio access network. The terminal device may also be a handheld device, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolving network, etc. with wireless communication functionality. The above is merely an example, and the practical application is not limited thereto.

Optionally, in the embodiment of the present invention, a new MAC CE (UL scheduling indicate MAC CE) indicated by a Control Element (CE) uplink scheduling may be added to the MAC in the standard protocol 38.321 or 36.321, where the CE functions as follows:
if the terminal equipment receives an uplink scheduling data request sent by the network equipment for 3 continuous subframes, no uplink data need to be transmitted to the base station in the RLC layer in the 3 subframes, and then the indication CE of the uplink scheduling of the base station terminal equipment is replied to the base station in the MAC layer when the third uplink scheduling request is sent. If the terminal device does not actively apply for the uplink resource in the subsequent subframe, the network device should not schedule the uplink resource, or the terminal device does not need to fill padding data (i.e. invalid data) for the scheduling request of the uplink of the base station. Therefore, the purpose of reducing padding data is achieved, the transmission of physical layer data is reduced, and the power consumption of terminal equipment and the resources of a base station are saved.
For example, as shown in Table 2, the CE may add a Logical Channel Identification (LCID) value of uplink data and control (UL-SCH), that is, table 6.2.1-2 Values of LCID for UL-SCH, to the standard protocol 38.321Table 6.2.1-2 for the base station to parse the CE.
