Embodiment 1

[0146] Embodiment 1: Termination of non-scheduled period initiated by UE

[0147] Such as Figure 5 As shown in FIG. 1 , it is a schematic flow diagram of a control method for TDM in-device coexistence interference coordination on the base station side in a specific application scenario proposed in Embodiment 1 of the present invention, which specifically includes the following steps:

[0148] In step S501, the UE initiates a non-scheduling cycle termination request to the LTE eNB, which may also be called a TDM interference coordination termination request.

[0149] The request message can be carried by the MAC (Medium Access Control) layer control unit MAC CE (Control Element), or it can be carried by the RRC signaling of the RRC (Radio Resource Control) layer, and can trigger a scheduling request to notify the LTE eNB of the request message Scheduling transmission is performed, and the scheduling request refers to a dedicated scheduling request (if the LTE eNB allocates de...

Embodiment 2

[0164] Embodiment 2: Termination of the non-scheduled period initiated by the UE

[0165] The reason why the UE initiates the termination of the non-scheduling period is the same as that in the first embodiment, but the difference from the technical solution in the first embodiment is that the technical solution in the second embodiment has a process of feedback from the LTE eNB to the UE request.

[0166] Such as Figure 6A with 6B As shown, it is a schematic flow diagram of a control method for TDM in-device coexistence interference coordination on the base station side in a specific application scenario proposed in Embodiment 2 of the present invention, specifically including the following steps:

[0167] In step S601, the UE initiates a non-scheduling cycle termination request to the LTE eNB, which may also be called a TDM interference coordination termination request.

[0168] The request message can be carried by the MAC (Medium Access Control) layer control unit MAC C...

Embodiment 3

[0179] Embodiment 3: TDM mode adjustment initiated by UE

[0180] Such as Figure 7 As shown, it is a schematic flow diagram of a control method for TDM in-device coexistence interference coordination on the base station side in a specific application scenario proposed in Embodiment 3 of the present invention, specifically including the following steps:

[0181] Step S701, the UE sends a TDM mode adjustment request to the LTE eNB.

[0182] The request can carry 1-bit adjustment request information and / or suggested TDM pattern, which can include scheduling period and non-scheduling period length mode, etc., and the request message can be carried by the MAC (Medium Access Control) layer control unit MAC CE (Control Element) , may also be carried by RRC signaling at the RRC (Radio Resource Control) layer, and may trigger a scheduling request to notify the LTEeNB to schedule and transmit the request message.

[0183] Among them, the reason why UE initiates TDM adjustment is:

Abstract

The embodiment of the invention discloses a method and equipment for controlling coexistence interference coordination in time division multiplex (TDM) equipment. By utilizing the technical scheme of the embodiment, coexistence interference coordination in the TDM equipment can be executed, so the coexistence interference coordination in the TDM equipment adopted by terminal equipment can be guaranteed to adjust immediately according to the variation of signal channels of a long term evolution (LTE) system, variation of a data transmission state and variation of current service demand, while the coexistence transmission performance of multiple wireless systems in the equipment can be guaranteed, and the connection property and systematic performance of the LTE system can be better guaranteed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a control method and equipment for co-existence interference coordination in TDM equipment. Background technique [0002] The rapidly growing smart terminal market requires simultaneous support of multiple wireless technologies in one device, such as LTE (Long Time Evolved, Long Term Evolution) and ISM (Industrial, Scientific and Medical), LTE and GPS (Global Positioning System, Global Positioning System) integrated into the same device. ISM originally refers to the frequency band allocated to industry, science and medicine. It is an unlicensed frequency band used for scientific research. Here it refers to the technology using this frequency band, including typical wireless technologies on wireless terminals such as WLAN and Bluetooth (Bluetooth). In-device coexistence may be referred to as ICO (in-device coexistence) for short. [0003] In the existing frequency plannin...
