摘要： Solutions pertaining to spectrum sharing between a terrestrial network (TN) and a non-terrestrial network (NTN) with interference control 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. There is a requirement on either or both of a directive gain and a directive emission power with respect to a network node of the TN such that interference between TN downlink (DL) transmissions and NTN uplink (UL) transmissions is less than a threshold.

摘要： In a wireless OFDM multi-carrier communication system, a mobile station obtains measurement result of a first received signal strength indication (RSSI) of a first preamble signal transmitted from a base station over a first radio frequency (RF) carrier. The mobile station also obtains signal offset information between the first RF carrier and a second RF carrier of the base station. In response to the measurement result and the signal offset information, the mobile station estimates a second RSSI of a second preamble signal transmitted by the base station over the second RF carrier without performing scanning over the second RF carrier. In one novel aspect, the mobile station identifies a carrier group containing multiple carriers that belong to the same base station. Measurement optimization, initial cell selection and cell reselection optimization, report reduction, and other carrier group based optimization can be achieved in the multi-carrier system based on identified carrier group.

摘要： A method of dynamic resource transaction in wireless OFDMA systems is proposed. In macro-femto overlay network architecture, network and traffic condition varies dynamically. Dynamic resource transaction is a powerful mechanism to achieve effective interference mitigation and flexible radio resource management to enhance resource utilization as well as to improve link performance. Dynamic resource transaction can be performed by signaling or message exchange through backhaul network or air-interface connections. The signal or message through backhaul network can be directly exchanged among multiple base stations or be routed through a centralized self-organizing network (SON) server. In one embodiment, dynamic resource transaction is used to achieve adaptive reservation region configuration, a solution to avoid interference and frequent handover for highspeed mobile stations.

摘要： Solutions pertaining to enhanced support for transmit-receive (Tx-Rx) gap in non-terrestrial network (NTN) communications are proposed. An apparatus implemented in a UE receives from a non-terrestrial (NT) network node of a network an uplink (UL) grant or a configuration that schedules an UL transmission (Tx). The apparatus performs the UL transmission to the NT network node within a transmit-receive (Tx-Rx) transition gap during which no downlink (DL) Tx from the NT network node is expected. The Tx-Rx transition gap includes an UL Tx duration, a pre-UL Tx gap (Gap_start) before a starting time of the UL Tx duration (t_start), and a post-UL Tx gap (Gap_end) after an ending time of the UL Tx duration (t_end). A starting timing of the Tx-Rx transition gap can be expressed as: t_start –timing advance (TA) –Gap_start. An ending time of the Tx-Rx transition gap can be expressed as: t_end –TA + Gap_end.

摘要： The present disclosure proposes schemes, techniques, designs and methods pertaining to frequency synchronization for integration of terrestrial network (TN) and non-terrestrial network (NTN) communications. Communications between a user equipment (UE) and a terrestrial network (TN) and communications between the UE and a non-terrestrial network (NTN) are established. A frequency shift in the communications between the UE and the NTN is compensated regardless of availability of information related to a movement of the UE and a relative location of the NT network node of the NTN with respect to the UE.
