摘要： Techniques for transmitting signals using time hopping or time and frequency hopping are described. In one design, a terminal selects different slots to use for transmission in multiple frames with time hopping. Each frame includes multiple slots, and each slot covers a particular time duration. The selected slots are at different time locations in the multiple frames. In another design, a terminal selects different resource units to use for transmission in multiple frames with time and frequency hopping. The selected resource units are at different time and frequency locations in the multiple frames. For both designs, the terminal sends a signal (e.g., a peer discovery signal) in the selected slots or resource units in the multiple frames. The terminal may detect for signals (e.g., peer discovery signals) from other terminals in slots not used for transmission by the terminal.

摘要： Methods and apparatus for increasing power efficiency and decreasing latency of communication of a mobile device operating in an unlicensed spectrum using global timing data are disclosed. The method includes receiving, at the mobile device, the global timing data from an external timing source, the mobile device communicating in the unlicensed spectrum, obtaining, at the mobile device, a time from the global timing data, and determining, at the mobile device, a wake time to switch the mobile device from a sleep state to an active state based on the time obtained from the global timing data.
