DYNAMIC UPLINK/DOWNLINK CONFIGURATION

摘要

A method comprises monitoring (501 ), in a user terminal (302), a PDCCH channel during an active period of a DRX cycle. For defining a TDD configuration for the terminal when an inactive period of the DRX cycle changes into an active period, the method further comprises monitoring downlink sub-frames and DwPTS sub-frames according to a downlink HARQ reference configuration until an update of the TDD configuration is received; monitoring the PDCCH channel for any sub-frames except for sub-frames scheduled or configured for uplink transmission by the downlink HARQ reference configuration until the update of the TDD configuration is received; and/or monitoring the PDCCH channel for sub-frames when the terminal monitors the PDCCH channel for paging. The method comprises counting (501), in the terminal (302), PDCCH sub-frames for DRX timers, by utilizing the TDD configuration with the least or most downlink sub-frames for the PDCCH sub-frame counting.
