摘要： Systems, methods, devices, and computer program products are described for discontinuous multi-carrier uplink management in a wireless communication system. Common timing parameters may be identified for use in relation to discontinuous uplink transmissions on each of a two or more wireless carriers concurrently transmitting from an access terminal. A first operational state is associated with a first wireless carrier, while a second, different state is associated with a second wireless carrier. The first carrier may be operated in the first operational state concurrently with the second carrier being operated in the second operational state, with each carrier operated in accordance with the common timing parameters.

摘要： Techniques for signaling acknowledgment status (e.g., ACK, NACK, or DTX) for up to four detected carriers according to 4C-HSDPA. In an exemplary embodiment, an ACK slot of an HS-DPCCH channel utilizes spreading factor 128 to accommodate two 10-symbol codewords per slot. The codewords may be dual-carrier codewords, enabling the acknowledgment status of up to four carriers to be signaled in each slot. A DTX-DTX codeword may be further provided to signal no detection of two carriers assigned to the same codeword. In an alternative exemplary embodiment, a codeword signaling acknowledgment status for two carriers may be repeated twice over a single slot.

摘要： Systems, methods, devices, and computer program products are described for transmission of downlink channel quality information and acknowledgment information in a multi-carrier wireless communication system. Channel quality information may be estimated for a number of downlink carriers. An uplink control channel may be configured in a flexible manner based on the number of activated carriers and whether those carriers are configured with MIMO. The feedback cycle for the channel quality information may remain constant.

摘要： Systems and methodologies are described that facilitate synthesizing a single baseband waveform from digital signals related to multiple carriers. Digital signals can be received relating to a plurality of carriers. The digital signals can result from spreading data symbols from transport blocks to create chip sequences, which can additionally be pulse shaped. The digital signals can be rotated in a positive or negative direction, such as according to a complex sinusoid or a negative representation thereof. The rotated signals can be combined or added to generate a single baseband waveform. The single baseband waveform can be converted to an analog signal, which can be up-converted and centered at a plurality of frequency carriers, which can be adjacent, assigned for transmitting the signal. In addition, optimizations can be provided to ensure threshold power ratio over the plurality of carriers for effectively transmitting jointly encoded signals.
