Abstract: The invention relates to a method for dynamically indicating a TDD reconfiguration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication.

Abstract: A data transmission method is performed by a first node, and the first node includes X encoding units that perform encoding in a first FEC mode. The method includes: first dividing, by the first node, to-be-encoded data into X groups of initial data, and encoding the X groups of initial data one by one by using the X encoding units, to obtain X groups of encoded data; and then distributing, by the first node, the X groups of encoded data to L links, to send the X groups of encoded data to a second node. Both X×N and X×K are integer multiples of L, N represents a length of a codeword of the first FEC mode, K represents a length of valid information bits in the codeword, and amounts of encoded data distributed to different links are the same.

Abstract: Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.
