摘要： Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.

摘要： A wireless communications system includes a shared TDM data channel for communications in different time slots with respective mobile stations (MSs), as well as dedicated channels. A first medium access control (MAC) multiplexing sublayer, provided in a base station controller, maps information of logical channels for communications services to the communications channels. A second MAC multiplexing sublayer maps information, mapped to the shared data channel in the first MAC multiplexing sublayer, to respective data units for communication in respective TDM time slots of the shared channel. The second MAC multiplexing sublayer handles scheduling, adaptive modulation and coding, and automatic retransmission of information on the shared data channel, as well as shared control channels for the shared data channel and channel quality feedback and data acknowledgement channels from the MSs.

摘要： The present invention provides a fast and efficient retransmission technique, which allows a link control layer to request retransmission of frames upon receiving information from an underlying physical layer that an unsuccessful attempt to transmit data was detected. In general, a failed attempt to transmit a frame is detected at a physical layer of a receiver. In response, the physical layer of the receiver sends a message to a link control layer of the receiver to indicate the failed attempt to transmit a frame was detected. Upon receipt of the message, the link control layer sends a retransmission message to a corresponding link control layer of a sender. The retransmission message is configured to cause the sender to retransmit the unrecoverable data associated with the corrupted frame.

摘要： In code division multiple access communication systems, there are three levels for updating locations of dormant mobile stations (MSs) and setting up fast call. In sector and are levels, the dormant MS send a layer 2 message containing a message type and MS identifier to a base transceiver station (BTS). Since the message is associated with the sector where the MS is located, the network is aware of the MS's location from the updated location. The dormant MS sends to the BTS a reconnect message containing a message type and an MS identifier. The MS's dormant to active state transition is initiated by the MS. In the communication network, sub-packet zone ID is broadcasted in the overhead message. The MS reports its location change on R-CSCH and the network with the BSC level control can page the MS within the zone where the MS sends the report.

摘要： A method and system for providing dynamic ARQ, on a per packet basis, in a wireless telecommunications access network. By taking into consideration both per packet QoS based on, for example, packet delay bound, and potential delays caused by retransmission, a dynamic NAK-based ARQ scheme is presented that dynamically adapts the retransmission parameters to the per packet QoS to provide improved radio link quality, particularly for non-delay sensitive services and applications. The ARQ parameters that are dynamically adjusted can include the number of retransmission rounds, and the number of retransmissions in each round.

摘要： Systems and methods for MIMO wireless transmission are provided. At the transmitter, a plurality of encoded packets are modulated, and the symbols are divided between several transmit antennas. The transmitter spreads some of the symbols of each packet using a respective subset of an available Walsh code space. A given transmit antenna then transmits part of each packet spread by the respective subset. In some implementations, this achieves the benefits of the PARC system, and at the same time achieves part of the benefits of the STTD system. Advantageously, only a single reverse link control channel is required if adaptive coding and modulation is to be performed.

摘要： A flexible frame arrangement for a CDMA wireless communications network is disclosed. A signal for transmission in the network includes several frames for transferring data between network nodes. At least one of the frames includes a hierarchical sub-frame structure having a physical layer frame and an interleaver block, a forward error control (FEC) block, and an automatic repeat request (ARQ) block. The sub-frame arrangement may be used in a spread spectrum wireless network such as CDMA2000 or W-CDMA. The FEC blocks transmit error control information and are subdivided into one or more of the ARQ blocks. Each ARQ block includes information bits and overhead bits such as cyclic redundancy code (CRC) bits and zero bits.

摘要： A base station, mobile station, and/or other terminal device includes physical layer (layer 1) protocol and link layer (layer 2) protocol that both include automatic retransmission request (ARQ) operations. The physical layer and link layer include enhancements that interact with one another to cause the link layer to inhibit ARQ operations while error recovery operations are pending at the physical layer. A transmitter packages link layer packet data units into physical layer frames and transmits the physical layer frames. A receiver responds to indicate either successful or unsuccessful transmission. The transmitting physical layer waits for the response and initiates error recovery operations when required. The receiving link layer, when it detects lost data packets, inhibits its ARQ operations to allow physical layer error recovery operations to complete.
