The control area is mainly used for transmitting control channels; the data region is mainly used for transmitting a data channel (PDSCH).

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
The invention provides a method and a device for controlling the interference resistance of a channel, aiming at a TDD LTE system, based on a TDD LTE wireless protocol, wherein the uplink interference and the downlink interference are in the same frequency band, and the method and the device can detect the current interference condition in real time, dynamically and adaptively adjust the frequency domain resource position occupied by the downlink control channel, improve the interference resistance of the control channel, optimize the integral performance of a cell and improve the system capacity.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an embodiment of the method of the present application.
The application provides an uplink service channel anti-interference method, which comprises the following steps of 101 to 103:
step 101, in an LTE TDD system, dividing continuous N RBs into M groups, and measuring interference in real time to obtain an interference measurement value of each RB group;
taking a bandwidth 20M (N = 100) as an example, an Operation Maintenance Center OMC (Operation Maintenance Center) configures a system format as TDD, an uplink-downlink ratio, a default system bandwidth 20M (100 RB), a PHICH symbol number, PCI, and CFI.
Preferably, in a preset interference detection period, measuring the interference of the M RB groups for multiple times; the interference measurement value is an average value obtained by carrying out multiple measurements in an interference detection period.
102, comparing the interference measurement value of each RB group with a preset threshold value, wherein the RB group higher than the threshold value is an unavailable RB group, and the RB group lower than the preset threshold value is an available RB group;
and 103, removing the unavailable RB group in the N RBs, and allocating the resource position of the downlink control channel by using the rest RBs.
For example, the physical resource location of each control channel (PCFICH, PHICH, PDCCH) is recalculated according to the existing protocol calculation method, and only the default system bandwidth (e.g. 100 RB) is replaced with the logical system bandwidth after the high-interference unavailable RB group is subtracted. This allows avoiding high interference RBs when the control channel actual physical resource location maps.
In step 103 (or step 201), the "existing protocol" refers to a method for determining the location of the physical resource of the control channel according to the requirements of the system bandwidth and the number of control channel symbols in the prior art, and is described in, for example, 36 series protocols (36.211, 36.212, or 36.213) of the 3GPP protocol.
In steps 101 to 103, preferably, the interference detection period and/or the threshold value are configured by a higher layer signaling. For example, an Operation Maintenance Center OMC (Operation Maintenance Center) configures a system interference detection period and an interference threshold value.
Fig. 2 is a flowchart of an embodiment of a method of the present application for a network device.
The method according to any one of the embodiments of the first aspect of the present application, for a network device, includes the following steps 201 to 204:
At this time, the Operation Maintenance Center OMC (Operation Maintenance Center) configures the system standard to be TDD, the uplink and downlink ratio, the default system bandwidth 20M (100 RB), the PHICH symbol number, PCI, CFI, the interference detection period, and the interference threshold.
preferably, the base station measures the interference of each RB group for multiple times in a preset interference detection period; the interference measurement value is an average value obtained by carrying out multiple measurements in an interference detection period.
For example, take N =100,m =10. And the base station measures the interference (NI) of the uplink PUSCH/PUCCH in real time and records a corresponding interference value according to each RB. The base station averages the interference measurement according to the interference detection period to obtain the interference average value of each RB in the period, and then divides 100 RBs into 10 RB groups for averaging.
Step 203, comparing the interference measurement value of each RB group with a preset threshold value, wherein the RB group higher than the threshold value is an unavailable RB group, and the RB group lower than the preset threshold value is an available RB group;
for example, the base station compares the interference average value of each group of 10 RBs with an interference detection threshold, and determines that the frequency band where the 10 RBs are located is a high interference corresponding value of 1 if the interference average value is greater than the threshold, and otherwise, determines that the frequency band is an interference-free corresponding value of 0.
For example, the base station sends 10 sets of interference values of RB, which total 10 bits, with a bit value of 0 representing no interference, RB available, 1 representing high interference, RB unavailable, and fills in and updates to 10 bits reserved in the MIB message (the default value of 10 bits reserved in the MIB message is 0), to the terminal device.
And step 205, removing the unavailable RB group in the N RBs, and allocating the position of the downlink control channel resource by using the rest RBs.
For example, the base station removes the high interference RB group from 100 RBs according to the 10 groups of RB interference situation, the remaining RBs are logical system bandwidths, and recalculates the physical resource locations of the control channels (PCFICH, PHICH, PDCCH) according to the existing protocol calculation method of step 201, except that the default system bandwidth (100 RBs) is replaced by the logical system bandwidth after the high interference is subtracted. This allows avoiding high interference RBs when the control channel actual physical resource location maps.
Fig. 3 is a flowchart of an embodiment of the method of the present application for a terminal device.
The method in any one embodiment of the first aspect of the present application, applied to a terminal device, includes the following steps:
For example, the terminal receives the MIB message sent by the base station to obtain reserved 10-bit information, where each bit represents the interference situation of 10 RBs.
for example, the terminal updates the interference situation of 100 RBs according to the received 10bit information, and then calculates the position of the control channel physical resource from the new position according to the method operation of step 205.
It should be noted that, according to the methods in steps 205 and 302, the base station and the terminal perform resource allocation based on the recalculated control channel physical resource location, and implement the same allocation scheme. And continuously and circularly executing the steps of the above embodiment in the next interference detection period.
