Problems solved by technology
However, 2G services on low-band networks may exist for a long time. One possible solution is to reserve part of the 2G network carrier frequency, and the LTE system can only use 5M bandwidth; The bandwidth is less than 10M, and the LTE system can still only use 5MHz bandwidth resources, resulting in waste of spectrum resources and difficulty in system upgrades. Therefore, terminals need to use flexible bandwidth to access cells

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0020] In order to improve the utilization of wireless network resources, the terminal needs to obtain resources scheduled by the network other than the standard bandwidth. When the terminal accesses the system to complete cell search and synchronization, the terminal can transfer to the extended freq...

The invention discloses a flexible bandwidth-based physical uplink control channel scheduling method, system, scheduling equipment and a flexible bandwidth-based terminal, relating to the field of mobile communications. The method includes: the network side device sends a scheduling message to the terminal that accesses the network in a flexible bandwidth mode, and the scheduling message includes indication information that the physical uplink control channel of the terminal is located at both ends of the aggregation frequency band where the terminal works, so that the terminal is at the terminal indicated by the indication information. The physical uplink control information is sent on the physical uplink control channel, and the aggregated frequency band includes a main frequency band and an extended frequency band. Thereby, the scheduling of the physical uplink control channel of the terminal based on the flexible bandwidth is realized.
Description
technical field [0001] The present invention relates to the field of mobile communication, in particular to a flexible bandwidth-based physical uplink control channel scheduling method, system, scheduling equipment and a flexible bandwidth-based terminal. Background technique [0002] Telecom operators have gradually obtained permission to refarm and deploy LTE networks in low-band spectrum resources, such as launching LTE networks on 800MHz and 900MHz 2G networks. However, 2G services on low-band networks may exist for a long time. One possible solution is to reserve part of the 2G network carrier frequency, and the LTE system can only use 5M bandwidth; If the bandwidth is less than 10M, the LTE system can still only use 5MHz bandwidth resources, resulting in waste of spectrum resources and difficulty in system upgrades. Therefore, terminals need to access cells with flexible bandwidth. [0003] How to schedule the physical uplink control channel of the terminal based on t...
