摘要： A system and method for wireless communication includes multiplexing an EUDC downlink control channel so that it is transmitted like a downlink dedicated channel (DL-DPCH). The EUDC downlink control channel can be multiplexed with the DL-DPCH by code or by both code and time. The EUDC downlink control channel may be multiplexed with a downlink dedicated physical data channel (DL-DPDCH), a downlink dedicated physical control channel (DL-DPCCH), or both. In one embodiment, the EUDC downlink control channel is multiplexed by adding a multicode channel to a current DL-DPCH and treating the EUDC downlink control channel as a dedicated channel with power control functionality.

摘要： In a method of transmitting control signals for uplink transmission of packet data, a control channel carrying control signal data that is shared by a plurality of users is transmitted in the downlink to the users. The shared control channel includes fields identifiable by, or specified for, different ones of the users, so that each field includes control signal data for a specified user for uplink transmission of packet data. The specified user decodes a corresponding field of the shared control channel to interpret the control signal data, and may transmit packet data in the uplink in accordance with the decoded control signal data.

摘要： In a method of transmitting control signals for uplink transmission of packet data in a communication network, control signal data related to scheduling a user for uplink transmission of packet data is transmitted over a single control channel. The single control channel may be configured based on the transmission mode the user is in for scheduling an uplink transmission from the user to the network, so that only one control channel is used, regardless of the transmission mode the user is in for scheduling the user for the uplink transmission. The control channel may be embodied as a sub-frame adapted to carry control information that is dependent based on the transmission mode the user is in for scheduling an uplink transmission from the user to the network.

摘要： In a method for aligning a plurality of physical channels for uplink transmission two or more physical channels may be aligned based on a timing offset so that the two channels are transmitted in the uplink at a time instant different than a time of uplink transmission for a third physical channel. Accordingly, the two physical channels may be code multiplexed with additional physical channels other than the third physical channel to generate a code-multiplexed signal to be used for uplink transmission. The timing offset information may be assigned to the user from a base station, for example, in order to align the two physical channels. Accordingly, an increase in peak-to-average power ratio my be avoided and/or reduced if multiplexing the two physical channels with other physical channels for uplink transmission.

摘要： An external memory based FIFO (xFIFO) apparatus coupled to an external memory and a register bus is disclosed. The xFIFO apparatus includes an xFIFO engine, a wDMA engine, an rDMA engine, a first virtual FIFO, and a second virtual FIFO. The xFIFO engine receives a FIFO command from the register bus and generates a writing DMA command and a reading DMA command. The wDMA engine receives the writing DMA command from the xFIFO engine and forwards an incoming data to the external memory. The rDMA engine receives the reading DMA command from the xFIFO engine and pre-fetches a FIFO data from the external memory. The wDMA engine and the rDMA engine synchronize with each other via the first virtual FIFO and the second virtual FIFO.

摘要： In the scheduling method of the present invention, scheduling grant messages for a user equipment are transmitted beginning in any time slot of a frame for a channel so long as the scheduling grant message does not exceed the frame. The scheduling grant message indicates user equipment is approved to transmit on an uplink dedicated channel. This downlink transmission and subsequent uplink dedicated channel transmission have a timing relationship such that no more than one user equipment will begin transmitting on a respective uplink dedicated channel at a time.
