Abstract: DRS signaling are described herein in which the DRS transmissions may be used in a Long Term Evolution (LTE)-Licensed Assisted Access (LAA) Secondary Cell that is subject to Listen Before Talk (LBT). In some implementations, the DRS transmission may include continuous symbol transmission in order to ensure that other nearby nodes, such as WiFi nodes, do not begin to transmit on the channel.

Abstract: In a Long-Term Evolution Licensed Assisted Access (LTE-LAA) environment, Received Signal Strength Indicator (RSSI) measurements may be taken by a User Equipment (UE) outside of transmission bursts of cells in the LTE-LAA environment. For example, a serving cell may indicate transmission burst timing, of the serving cell, via Radio Resource Control (RRC) signaling. Non-serving cells may align transmission burst timing with the outputting of a Discovery Reference Signal (DRS). The serving cell may provide DRS configuration information, which may indicate the timing of the DRS of the non-serving cells. The UE may use the DRS configuration information to measure the RSSI of the non-serving cells outside of their transmission bursts.

Abstract: When performing a contention protocol, such as Listen-Before-Talk (LBT), an Long Term Evolution (LTE)-Licensed Assisted Access (LAA) node dynamically adapts the ED threshold used by the LTE-LAA node depending on whether other transmission nodes are detected at the frequency components that are to be used by the LTE-LAA node. In one implementation, the ED threshold value may initially be set to a conservative value, and when other transmissions nodes are not detected, the ED threshold value may be set to a more aggressive value. In another implementation, the ED threshold value may initially be set to a more aggressive value, and only when another transmission node is detected, the ED threshold value may be set to a more conservative value. In yet another possible implementation, the ED threshold value and the transmit power may be proportionally modified, for a particular UE, based on a parameter associated with the UE.
