摘要： A method for generating a code, a method for encoding and decoding data, and an encoder and a decoder performing the encoding and decoding are disclosed. In an embodiment, a method for lifting a child code from a base code for encoding and decoding data includes determining a single combination of a circulant size, a lifting function, and a labelled base matrix PCM according to an information length and a code rate using data stored in a lifting table. The lifting table was defined at a code generation stage. The method also includes calculating a plurality of shifts for the child code. Each shift is calculated by applying the lifting function to the labelled base matrix PCM with a defined index using the circulant size and using the derived child PCM to encode or decode data.

摘要： Backwards compatibility may be achieved by transmitting an alternating pattern of uplink TPC commands in uplink timeslots. In one example, a served user equipment (UE) receives a downlink TPC command from a serving base station during a downlink timeslot in a sequence of downlink timeslots, and generates an uplink TPC command based on a received power level of the downlink TPC command. The served UE may then transmit the uplink TPC command in an uplink timeslot mapped to the downlink timeslot in which the downlink TPC command was received, as well as transmit an alternating pattern of uplink TPC commands in other uplink timeslots. The alternating pattern of uplink TPC commands may cause a neighboring base station to effectively maintain its transmit power level.

摘要： Transitioning from basic higher order MIMO channel estimation to enhanced higher order MIMO channel estimation (and vice-versa) can be accomplished through the signaling of high-speed downlink packet access (HSDPA) shared control channel (HS-SCCH) orders to next-generation user equipments (UEs). A base station can be configured to send an HS-SCCH order indicating activation of scheduled pilot channels, and then begin transmitting the scheduled pilot channels after receiving an ACK message from at least one next-generation UE. A base station can also be configured to send an HS-SCCH order indicating de-activation of scheduled pilot channels to next-generation UEs scheduled for downlink transmission, and then stop transmitting the scheduled pilot channels after receiving ACK messages from each next-generation UE. Alternatively, scheduled pilot channels may be activated/de-activated without receiving an ACK message from some or all of the next-generation UEs scheduled for downlink transmission.
