Abstract: A coexistence interference mitigation method is provided. In a wireless network, a wireless device is equipped with multiple radios in the same device platform. The wireless device also has a control entity that communicates with the multiple co-located radio modules. A first radio module receives a notification from the control entity. The notification informs a critical signaling status of a second radio module co-located with the first radio module. Upon receiving the notification, the first radio module stops uplink transmission due to coexistence interference and transmits a coexistence indicator to its serving eNB. After a certain period, the first radio module receives a second notification that informs a completion status of the critical signaling of the second radio module. Upon receiving the second notification, the first radio module resumes uplink transmission and transmits a coexistence resume indicator to the eNB.

Abstract: Methods for preventing coexistence interference between a Bluetooth Low Energy (BLE) radio and a collocated LTE radio are provided. In a first solution, the BLE radio adds padding bytes to BLE packets such that the total packet length falls in a specific range to prevent coexistence interference. In a second solution, the BLE radio limits the total BLE packet length to a predefined length to prevent coexistence interference. In a third solution, the data rate for transmitting the BLE packets is higher than a predefined rate to prevent coexistence interference. In a fourth solution, the BLE radio dynamically adjusts the time inter-frame-spacing (T_IFS) value to prevent coexistence interference with the collocated LTE radio.

Abstract: 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.

Abstract: A unified two-stage network entry procedure is provided for OFDM multi-carrier wireless communications systems. During a first stage, a mobile station performs a common network entry procedure using a primary radio frequency carrier and then exchanges multi-carrier capability information with a base station. In one embodiment, the base station transmits a network entry allowance indicator to assist the mobile station in selecting the primary carrier. The network entry allowance indicator comprises information of preference of one or more available carriers. During a second stage, the mobile station enables multi-carrier transmission over multiple frequency channels if both the mobile station and the base station support multi-carrier capability. Before enabling multi-carrier transmission, the mobile station may optionally perform additional ranging by transmitting a ranging request for a secondary carrier. In one embodiment, the base station replies with a ranging response in response to the ranging request through the primary carrier.

Abstract: A method of reducing gray energy consumption and achieving optimal gray energy saving for carbon neutralization is proposed. In a cellular network, each cell or BS (group of cells) has renewable (green) and non-renewable (gray, on-grid power) energy sources. The renewable (green) energy is highly variable and unpredictable, while non-renewable (gray, on-grid power) is stable but is not renewable and thus has more carbon impact. Each cell or BS (group of cells) services is associated UEs when it is on. In one novel aspect, a cell or BS (group of cells) that consumes more non-renewable energy can give some or all of its served UEs to another cell or BS (group of cells) that consumes less non-renewable energy.

Abstract: A method of multi-radio interworking to provide integrated cellular and WLAN access for a multi-radio device is provided. A serving base station in a cellular network first obtains wireless local area network (WLAN) information and then forward the WLAN information to a serving device such that the serving device is capable to connect with both the cellular network and a WLAN. The WLAN information may comprise scanning information, WLAN QoS information, WLAN layer-3 information, or additional WLAN access point information. The WLAN information is forwarded based on triggering events associated with the serving base station information, WLAN coverage information, or the serving device information. Based on the received WLAN information, when entering WLAN coverage, the serving device activates its WLAN access to forward traffic from the cellular access network to the WLAN access network. When leaving WLAN coverage, the serving device deactivates its WLAN access to save power consumption.

Abstract: Various examples and schemes pertaining to enhanced cell selection mechanisms in mobile communications are described. A user equipment (UE) performs a cell selection or reselection procedure to select a cell of a wireless network and establishes a wireless connection with the selected cell. In performing the cell selection or reselection procedure, the UE determines a frequency band and a subcarrier spacing (SCS) configuration by checking a profile, and the UE performs the cell selection or reselection procedure in the frequency band based on the SCS configuration.
