摘要:
Systems and methods for dynamically adjusting the transmission time interval (TTI) for a communications system are presented. The described aspects provide for dynamically adjusting the TTI in a communication session between a base station or nodeB and a wireless device or user equipment between a shorter TTI, which can provide increased data throughput and lower power consumption, and a longer TTI, which can provide more rugged communication link connections. By dynamically adjusting the TTI, the communications link can be optimized for the given communication channel conditions. Determinations, based on indicia related to the communications system conditions, can be employed in dynamic TTI adjustment. These determinations can be formed centrally at the Radio Network Controller (RNC), at the RNC supplemented with user equipment (UE) available information, or formed in a distributed manner between the RNC and UE across a communications system.

A base station can employ a shared resource, such as a control channel, for communication with a mobile device. The mobile device can be granted the exclusive access to the shared resource for a limited time. The exclusive access can be such that there is not a limit in message size that can be transferred across the shared resource. To improve operation, the exclusive grant can be applied until it is determined that appropriate packets are transferred.

Providing for improved wireless communications for user equipment (UE) in a semi-active state is described herein. By way of example, a base station can employ particular wireless channel resources, monitored by a UE in a CELL_FACH state for instance, to trigger channel feedback information from the UE. The trigger can comprise an explicit order instructing the UE to provide data in response, or can include a portion of downlink traffic targeting the UE, where the UE is configured to respond in a suitable manner to receipt of traffic data. The UE can maintain the CELL_FACH state in receiving to and responding to the trigger, and can further receive subsequent traffic data in such state. Accordingly, the subject disclosure provides for improved efficiency and reliability in semi-active state wireless communications.

Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.

摘要:
Systems and methodologies are described that facilitate and/or effectuate transmission of circuit switched voice over packet switched networks. The systems and methodologies provide for the receiving a first packet originating from access terminals and/or user equipment, determining within which hybrid automatic repeat request (HARQ) the first packet is received, ascertaining an amount of delay that is applied to the first packet before the first packet is forwarded into a core circuit switched network; and establishing a periodic time interval within which to convey subsequent packets that originate from the communicating access terminal and/or user equipment.

Techniques for controlling transmission of packets on multiple links are described. In one design, a transmitter may generate packets of data for a receiver, assign the packets with sequence numbers from a single sequence number space, demultiplex the packets into multiple streams for multiple links, and send each stream of packets on the associated link to the receiver. The receiver may receive some packets in error, and the correctly received packets may be out of order. In one design, the receiver may maintain the largest sequence number of correctly received packets for each link. After detecting at least one missing packet, the receiver may send status information conveying the missing packet(s) and the largest sequence numbers for all links to the transmitter. The transmitter may use the largest sequence numbers for all links and its packet-to-link mapping to determine whether to quickly resend each missing packet or wait.
