Method and system for reporting interference information, and UE

A system for reporting interference information, comprising:

• User Equipment (UE) and a network side, wherein
• the UE is configured to report frequency information of a first radio technology or report frequency information of a first radio technology and additional interference information to the network side when the UE detects a change in an interference state of in-device coexistence interference;
• or
• the UE is configured to report frequency information of a first radio technology to the network side when the UE detects a change in an interference state of in-device coexistence interference;
• and to report additional interference information to the network side after the UE receives from the network side an instruction of requiring reporting the additional information;
• and
• the network side is configured to instruct the UE to report the additional interference information;
• wherein the frequency information of the first radio technology is undisturbed frequency information and/or disturbed frequency information, and the disturbed frequency information refers to a disturbed operation frequency range and/or disturbed operation frequencies of the first radio technology which produces in-device coexistence interference with enabled other radio technologies when the first radio technology and other radio technologies operate simultaneously;
• wherein when the UE reports the frequency information of the first radio technology to the network side, the UE is further configured to report the frequency information of the first radio technology to the network side by reporting a lower limit frequency and/or an upper limit frequency of a frequency range or by reporting a disturbed frequency range using an index number of a frequency band, wherein the lower limit frequency is a left end value of an interval of the disturbed frequency range, and the upper limit frequency is a right end value of the interval of the disturbed frequency range;
• wherein
• reporting the lower limit frequency and/or the upper limit frequency of the frequency range comprises:
• reporting a specific value or an Evolved Universal Mobile Telecommunication System (UMTS) Terrestrial Radio Access Absolute Radio Frequency Channel Number (EARFCN);
• and
• reporting the frequency range using the index number of the frequency band comprises:
• searching the index number corresponding to the frequency range in a frequency information list according to the frequency information list pre-determined by the UE and a network or the frequency information list pre-defined by a protocol, and notifying the index number to the network side when the UE reports the frequency information of the first radio technology.

User Equipment (UE) comprising at least a first radio transceiver and a second radio transceiver, wherein the first radio transceiver uses a first radio technology, the second radio transceiver uses a second radio technology, and an operation frequency range of the first radio technology and an operation frequency range of the second radio technology are overlapped or neighbouring at least in part;

• wherein the UE is configured to report frequency information of the first radio technology used by the first radio transceiver or report frequency information of the first radio technology and additional interference information to a network side when the UE detects a change in an interference state of In-device Coexistence Interference;
• or
• the UE is configured to report frequency information of the first radio technology used by the first radio transceiver to a network side when the UE detects a change in an interference state of in-device coexistence interference;
• and to report additional interference information to the network side after receiving from the network side an instruction of requiring reporting the additional information;
• wherein the frequency information of the first radio technology is undisturbed frequency information and/or disturbed frequency information, and the disturbed frequency information refers to a disturbed operation frequency range and/or disturbed operation frequencies of the first radio technology which produces in-device coexistence interference with enabled other radio technologies when the first radio technology and other radio technologies operate simultaneously;
• wherein when the UE reports the frequency information of the first radio technology to the network side, the UE is further configured to report the frequency information of the first radio technology to the network side by reporting a lower limit frequency and/or an upper limit frequency of a frequency range or by reporting a disturbed frequency range using an index number of a frequency band, wherein the lower limit frequency is a left end value of an interval of the disturbed frequency range, and the upper limit frequency is a right end value of the interval of the disturbed frequency range;
• wherein
• reporting the lower limit frequency and/or the upper limit frequency of the frequency range comprises:
• reporting a specific value or an Evolved Universal Mobile Telecommunication System (UMTS) Terrestrial Radio Access Absolute Radio Frequency Channel Number (EARFCN);
• and
• reporting the frequency range using the index number of the frequency band comprises:
• searching the index number corresponding to the frequency range in a frequency information list according to the frequency information list pre-determined by the UE and a network or the frequency information list pre-defined by a protocol, and notifying the index number to the network side when the UE reports the frequency information of the first radio technology.
