Description
Technical field
This application involves field of communication technology, in particular to a kind of LTE PUCCH channel and place when other channel conflictions
Manage method and system.
Background technique
Currently, Long Term Evolution (Long Term Evolution, LTE) provide the user as 4G mainstream technology
The data transmission service of high speed.It is adopted in some application scenarios based on LTE technology, such as in Power System Intelligent electric network data
Collect in scene, downlink transfer acquisition instructions, the collected various types data of uplink, part intelligent electric meter can be arranged in road
The place that damage is big, covering is weak, for example, under well lid, basement etc., in this case, the signal-to-noise ratio of uplink receiving is very low.
In Power System Intelligent electric network data acquisition net, designed TDD system radio frames frame structure is as shown in Figure 1.
To support the demand, PUCCH channel is also required to design a variety of PUCCH formats, can do design as shown in table 1,
Middle format 0,1,3 occupies 1 radio frames, and format 2 occupies 2 radio frames.
1 PUCCH format of table
| PUCCH format | Modulation system | Information bit Mbit | Occupy OFDM symbol number |
| 0 | BPSK | 1 | 4 |
| 1 | BPSK | 1 | 27 |
| 2 | BPSK | 1 | 54 |
| 3 | BPSK | 1 | 8 |
User can choose different PUCCH formats and be mapped, for being in letter according to the covering grade locating for oneself
Environment preferable user in road, which can choose, occupies the less PUCCH format of resource, and the user poor for channel circumstance can select
It takes and occupies the more PUCCH format of resource.
There are key industrys and national important mechanism (such as army) etc. largely with narrowband system in 230MHz frequency range
System, the 230MHz energy Internet of Things working frequency points based on TD-LTE are dispersed in other between frequency points of wireless communication system, phase
The spectral leakage of adjacent different system may bring strong jamming to other systems.Therefore, it is necessary to solve this system with narrowband system
The coexistence problems of system influence to avoid this system in the normal work with narrowband systems, at the same reduce with narrowband systems to this
It is influenced brought by the interference of system.In order to solve the above technical problems, a solution is the letter when base station side is to uplink
Road environment measures, and discovery uplink has the resource of interference, and carries out evacuation processing in scheduling, defaults in system design
Every 40 radio frames reserve a radio frames and do special quiet frame, do not send uplink signal in the radio frames, which is
No unlatching, is configured by RRC signaling.
In existing LTE protocol and in general private network design, provided if the transmission of PUCCH channel is encountered with other uplinks
The case where source conflicts, it will not generally handle, still be sent and received in original resource, will lead to PUCCH channel in this way and held
The content of load can not correctly be demodulated by base station side.
