Method for wireless communication in a device with co-existence radio

摘要

Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are co-existed/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as WiFi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference.

主权项

1. A method comprising:
serving a user equipment (UE) over a serving cell by a serving base station in a wireless communication system; obtaining UE capability information that indicates in-device coexistence (IDC) capability of the UE, wherein the existence of a coexisting radio device is indicated by the UE capability information; forwarding IDC information to a target base station, wherein the IDC information comprises at least the UE capability information; and handing over the UE to a cell in another frequency that is away from a serving frequency of the serving cell if the serving frequency is near the frequency of the coexisting radio device.
