First Claim
Patent Images
1. A method, comprising:
- obtaining timing of one or more uplink/downlink configuration indication bits to be examined from a received indication of the timing of the one or more uplink/downlink configuration indication bits;
examining a value of the one or more uplink/downlink configuration indication bits in a predetermined region in a received downlink time division duplex subframe of wireless data transmission, the predetermined region indicated by the obtained timing; and
determining a time division duplex uplink/downlink configuration for a predetermined configuration period using the examined value of the one or more uplink/downlink configuration indication bits.

Abstract
A method and apparatus which allows dynamic TDD UL/DL configuration that is able to adapt to an instantaneous traffic situation. The values of at least one uplink/downlink configuration indication bit in a predetermined region in a received downlink time division duplex subframe of wireless data transmission are examined. A time division duplex uplink/downlink configuration for a predetermined configuration period is determined based on the examined values.
