Emergency data transmission over unlicensed radio frequency spectrum band
摘要
說明書
In some examples, the method may include performing a CCA at an adjusted CCA opportunity of the first node. The method may also include transmitting at least a portion of the emergency data, by the first node, during a frame following the adjusted CCA opportunity if the CCA is successful. In some examples, the method may further include allocating all available transmission resources in the frame following the adjusted CCA opportunity to the transmission of the emergency data until the emergency data has completed transmission. In some examples, the method may further include transmitting the emergency data by the first node over a subset of subcarriers. The subset of subcarriers may be determined based on the first operator of the first node. In some examples, the method may further include performing the CCA concurrently with at least a second node associated with a second operator, where the second node has emergency data to transmit.
In some examples, the method may include performing a CCA concurrently with at least a second node associated with a second operator, where the second node has non-emergency data to transmit and a default CCA opportunity of the second node collides with the adjusted CCA opportunity of the first node. In some examples, the method may further include transmitting the emergency data over a joint MBMS including the first operator and the second operator. In some examples, the method may further include forming the joint MBMS in response to a determination that the first node and the second node have the same emergency data to transmit. In some examples, the method may further include transmitting the emergency data according to a coordinated multipoint (CoMP) operation between the first node and the second node.
In some examples of the method, the first node may include a base station or a UE.
