Title
(EN) UPLINK SCHEDULING FOR LICENSE ASSISTED ACCESS
Abstract
(EN)
Uplink scheduling for license assisted access (LAA) mode systems is discussed in which a base station transmits a conditional grant to served user equipments (UEs) that include a transmission configuration for uplink transmissions. The transmission configuration includes the parameters necessary for the UE to perform transmissions. Before the beginning of a uplink transmission opportunity a base station transmits an uplink activation grant over a contention-based shared carrier to the served UEs. The uplink activation grant indicates the transmission opportunity to the UEs and may identify a subset of UEs out of the served UEs that are available for transmission. The base station first secures the channel before transmitting the uplink activation grant. Upon receipt of the uplink activation grant the UEs determine whether they will perform uplink transmissions and if so transmit the uplink data according to the transmission configuration.
