    摘要: A method and apparatus allocate acknowledgement channels in a communication network. A linking scheme is established between indices of physical hybrid automatic repeat-request indicator channels (PHICHs), and a combination of indices of control channel elements (CCEs) or indices of physical resource blocks (PRBs) and indices of demodulation reference signals (DMRSs). A scheduling grant is transmitted to a user equipment (UE) by using a plurality of CCEs. In response to receiving a data packet and a DMRS from the UE, an index of a PHICH within the plurality of PHICHs is determined based on at least one index of the CCEs used to transmit the scheduling grant or at least one index of the PRBs used to transmit the data packet, and an index of the DMRS in accordance with the linking scheme established. The BS transmits an acknowledgement signal to the UE using the PHICH indicated by the determined index.

    摘要: Prior to a change in a configuration, such as a change to the carrier frequency, bandwidth, base station type, and so forth of the base station, the base station can inform a subscriber station to prepare for the reconfiguration by sending a message to the subscriber station. The message informs the subscriber station regarding the change in configuration and a timing regarding the change. The base station can command the subscriber station to handover to the serving base station with the new configuration or the subscriber station can choose to handover to the serving base station with the new configuration. The subscriber station can perform network reentry to the serving base station with the new configuration at the time of or after the new configuration is effective. A communication context between the stations can be maintained and the network reentry can be optimized by omitting one or more operation procedures.

    摘要: A base station comprises a transmitter configured to transmit a downlink frame. The downlink frame comprising a first configuration message associated with the configuration of Enhanced-Multicast Broadcast Service (E-MBS). The first configuration message comprises a field with an indicator to indicate a next configuration message to be decoded by a subscriber station. The subscriber station, upon decoding the first configuration message, refrains from decoding subsequent configuration messages that precede the next configuration message to be decoded by the subscriber station in accordance with the indicator.

    摘要: The present invention concerns methods for efficiently supporting Voice over Internet Protocol (VoIP) on the Forward Packet Data Channel (F-PDCH) in CDMA 2000 1xEV-DV systems. Active speech in VoIP is encoded using, for example enhanced variable rate codec (EVRC), which produces 171, 80 and 16 bits per 20 ms of speech for Rate 1, Rate ½ and Rate ⅛, respectively. However, about 60% of the time a user is inactive during a speech session, so an inordinate amount of system bandwidth is comprised of rate ⅛ VoIP packets. In one embodiment of the present invention the apparatus of the present invention identifies the Rate ⅛ voice frame packets and discards them. In another embodiment of the present invention, the apparatus of the present invention identifies the Rate ⅛ voice frame packets and selects some of them for further transmission. In both embodiments the efficiency of channel utilization is increased since the amount of channel band width used to communicate relatively little information, e.g., gaps of silence, is decreased.
