    摘要: A guard period for switching between uplink and downlink subframes is created by shortening an uplink subframe, i.e., by not transmitting during one or more symbol intervals at the beginning of the subframe interval. A grant message includes signaling indicating when a shortened subframe should be transmitted. An example method is implemented in a first wireless node configured to transmit data in transmit subframes occurring at defined subframe intervals and having a predetermined number of symbol intervals. This example method includes determining (1620) that a transmit subframe is to be shortened, relative to the predetermined number of symbol intervals and, in response to this determination, shortening (1630) transmission of the transmit subframe by not transmitting during a beginning portion of the subframe interval for the transmit subframe and transmitting during the remainder of the subframe interval.

    摘要: According to certain embodiments, a wireless device (100) is capable of using a synchronization signal block, SSB, for synchronization. The wireless device receives (1502), from a network node (120), an indication whether an additional synchronization signal is available for use. The indication is received via downlink control information, DCI. The indication is received during paging. In response to the indication indicating that the additional synchronization signal is available for use, the wireless device performs synchronization (1510) using the additional synchronization signal. In response to the indication indicating that the additional synchronization signal is not available for use, the wireless device performs synchronization (1512) using the SSB without the additional synchronization signal.
