Abstract: Aspects of the disclosure provide a handoff procedure for a satellite communication system such as a broadband low-Earth orbit (LEO) satellite communication system. A gateway and a user terminal (UT) coordinate and schedule a satellite-to-satellite handoff in such a way that there are no messaging round-trip delays between the last return service link (RSL) packet transmitted from the user terminal to the source satellite and the first RSL packet transmitted from the user terminal to the target satellite. Therefore, an outage on the return link (from the user terminal to the gateway) can be limited to the actual time for moving the antenna feed from the source satellite to the target satellite. Furthermore, an outage on the forward link (from the gateway to the user terminal) can be limited to a single round-trip delay in addition to the time for moving the antenna feed.

Abstract translation: 本公开的方面提供了诸如宽带低地球轨道（LEO）卫星通信系统的卫星通信系统的切换过程。 网关和用户终端（UT）协调和调度卫星到卫星的切换，使得在从用户终端发送到源的最后一个返回服务链路（RSL）分组之间不存在消息往返延迟 卫星和从用户终端发送到目标卫星的第一RSL分组。 因此，返回链路（从用户终端到网关）的中断可以限于将天线馈送从源卫星移动到目标卫星的实际时间。 此外，除了移动天线馈送的时间之外，前向链路（从网关到用户终端）的中断可以被限制为单个往返延迟。

Abstract: Techniques of frequency spectrum usage in a wireless communication system include configuring two or more downlink carriers, each having a downlink carrier center frequency, to have a total occupied bandwidth that is constrained within an allocated downlink frequency spectrum. Further, the techniques include transmitting, to a user equipment (UE), two or more downlink carrier center frequency indicators that each identify a downlink carrier center frequency of each of the two or more downlink carriers. Also, the present techniques may include transmitting, to the UE, at least one uplink carrier center frequency indicator that at least relatively identifies at least one uplink carrier center frequency of at least one uplink carrier that is configured to have an independent, variable offset relative to one or more of the more than two downlink carriers. As such, these aspects allow new ways of squeezing carriers into the downlink while not impacting UE transmitter complexity.

Abstract: A method and apparatus for operating a controller for a satellite communications system during inter-beam handovers. In some aspects, the controller may perform an inter-beam handover by switching communications with a user terminal from a first beam to a second beam of a satellite. The controller receives a feedback message form the user terminal, via the first beam, after the inter-beam handover is completed, and may then selectively retransmit data to the user terminal via the second beam based at least in part on the feedback message.

Abstract: Various aspects of the disclosure relate to controlling the transmit power of a satellite by controlling a duty cycle associated with satellite transmission. In some implementations, a satellite network portal (SNP) may send waveforms to a satellite that relays the waveforms to user terminals (UTs). The SNP may control the duty cycle of the waveform transmission (e.g., by transmitting on a subset of a subframe) to thereby control an average transmission power of the satellite when the satellite transmits to the UTs. In some implementations, a satellite or UT may control the duty cycle of transmission by the satellite (e.g., by transmitting on a subset of a subframe) to thereby control an average transmission power of the satellite when the satellite transmits.

Abstract: The present patent application discloses a method and apparatus for activating or de-activating a secondary carrier, comprising informing a serving radio network controller when a secondary carrier was activated or de-activated, receiving a confirmation from the serving radio network controller that non-serving NodeB cells have achieved synchronization, and scheduling a UE upon receiving confirmation. In another example, the present patent application discloses a method and apparatus for de-activating a secondary carrier, comprising controlling de-activation of the secondary carrier using high-speed shared control channel orders, receiving acknowledgement of said high-speed shared control channel orders, and informing a serving radio network controller when the secondary carrier was de-activated.
