摘要： Solutions pertaining to configuration of spectrum sharing between a terrestrial network (TN) and a non-terrestrial network (NTN) are disclosed. An apparatus implemented in a UE communicates with a non-terrestrial (NT) network node of the NTN by resource sharing with the TN. The resource sharing involves resource sharing with pairing of uplink (UL) and downlink (DL) transmissions of the NTN and the TN.

摘要： The present disclosure proposes schemes, techniques, designs and methods pertaining to timing handling for integration of terrestrial network (TN) and non-terrestrial network (NTN) communications. Communications between a user equipment (UE) and a TN node and communications between the UE and an NTN node are established. The UE compensates for a first propagation delay in the communications between the UE and the NTN node, and the UE is able to obtain a second propagation delay between the UE and the NTN node.

摘要： In a non-terrestrial network (NTN), the propagation delay between satellite/base station and UE is much larger than that in a terrestrial network (TN). In order to well integrate the TN and the NTN in a system, methods and systems for handling timing issues are proposed. By modifying the timing handling mechanisms used in the TN network, the timing handling mechanisms can be used in the NTN network. In this invention, timing compensation mechanisms done by satellite/base station or by UE for NTN network are proposed for both cases that UE has relative location information of UE and satellite and UE has no relative location information of UE and satellite.

摘要： A method of implicit signaling to support In-Device coexistence interference avoidance is provided. A UE sends an IDC interference indication to an eNB. The indication indicates that a serving frequency becomes unusable due to a coexistence interference problem. The indication does not explicitly indicate a frequency index or a frequency location of the unusable serving frequency. The eNB determines the serving frequency as unusable in an implicit manner. The eNB also determines an implied unusable frequency region based on the received IDC indication. The implied unusable frequency region is between the serving frequency and the ISM band. In one advantageous aspect, the eNB configures a condition for the UE, such that the UE is refrained from sending IDC interference indications unless the condition is satisfied.

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 TDM in-device coexistence (IDC) interference avoidance is proposed. In a wireless communication device, a first radio module is co-located with a second radio module in the same device platform. The first radio module obtains traffic and scheduling information of the second radio module. The first radio module then determines a desired TDM pattern based on the traffic and scheduling information to prevent IDC interference with the second radio module. The first radio module also transmits TDM coexistence pattern information based on the desired TDM pattern to a base station. In one embodiment, the TDM coexistence pattern information comprises a recommended TDM pattern periodicity and a scheduling period to maximize IDC efficiency subject to limited level of IDC interference possibility. In one specific example, the TDM coexistence pattern information comprises a set of discontinuous reception (DRX) configuration parameters defined in long-term evolution (LTE) 3GPP standards.

摘要： A method to trigger in-device coexistence (IDC) interference mitigation is provided. A wireless device comprises a first radio module and a co-located second radio module. The first radio module measures a received radio signal based on a plurality of sampling instances. A control entity obtains Tx/Rx activity of the second radio module and informs Tx/Rx timing information to the first radio module. The first radio module determines a measurement result based on the obtained timing information. The first radio module triggers an IDC interference mitigation mechanism if the measurement result satisfies a configurable condition. In one embodiment, the first radio module reports IDC interference information and traffic pattern information of the second radio module to a base station for network-assisted coexistence interference mitigation. The IDC triggering mechanism prevents unnecessary and arbitrary IDC request from the device and thus improves network efficiency.

摘要： A method of multi-radio interworking to provide integrated cellular and wireless local area network (WLAN) access for a multi-radio device is provided. A serving base station in a cellular network first obtains WLAN information and then forwards the WLAN information to a serving device such that the serving device is capable of connecting 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 serving base station information, WLAN coverage information, or serving device information. Based on the received WLAN information, when entering WLAN coverage, the serving device activates its WLAN access to forward traffic from cellular access network to WLAN access network. When leaving the WLAN coverage, the serving device deactivates its WLAN access to save power consumption.

摘要： Carrier pre-assignment is applied in multi-carrier handover operation to mitigate the impact to the user experience during handover and to achieve various objectives of call admission control in wireless multi-carrier OFDM networks. With carrier pre-assignment, a mobile station communicates its multi-carrier information to a target base station. The target base station pre-assigns secondary carriers to fulfill the requirements of the mobile station. In a first embodiment, a break-before-entry (BBE) multi-carrier handover procedure with carrier pre-assignment is provided. In a second embodiment, an entry-before-break (EBB) multi- carrier handover procedures for both inter-FA and intra-FA with carrier pre-assignment are provided. The multi-carrier handover procedures with carrier pre-assignment may be applied to 2-to-2 or N-to-N carriers handover situation. Because target secondary carriers are pre- assigned before handoff, the mobile station is ready for data transmission over multiple carriers after handover without additional carrier assignment procedure.
