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.

摘要： A power control method to mitigate in-device coexistence (IDC) interference is provided. A wireless communication device (UE) is equipped with a first LTE radio module and a second co-located WiFi/BT/GSNN radio module. Upon detecting coexistence or IDC interference, the UE applies power control method to mitigate the interference. In a first embodiment, the LTE radio module adjusts its power parameters locally without informing the serving eNB. In a second embodiment, the LTE radio module adjusts its power parameters and implicit informs the eNB through existing PHR reporting. In a third embodiment, the LTE radio module changes its power or power class and explicitly informs the eNB through UE capability or new RRC message or MAC CE. Power control can be used as a low cost and lightweight solution before applying other heavyweight solutions that either require more resource or control overhead, or have higher impact on throughput.

摘要： A method of providing Local IP Access (LIPA) indication is proposed. In one novel aspect, an enhanced cell selection method is proposed using LIPA capability information. Based on LIPA capability related information, a UE is able to prioritize LIPA-capable cells and establish a corresponding packet data network (PDN) connection accordingly. In one embodiment, LIPA information is informed to the UE via Non Access Stratum (NAS) signaling. The UE stores LIPA capability information when receiving a NAS message from a mobility management entity (MME). Later on, when the UE performs cell selection or reselection in idle mode, the UE can use the stored LIPA capability information to prioritize LIPA-capable cells.
