    摘要: The present invention provides techniques for the retransmission of packets of data. One device comprises a transmission unit adapted to retransmit all previously transmitted packets transmitted during a predetermined time interval, instead of just a single packet, when a received signal indicates that at least one previously transmitted packet contains corrupted data.

    摘要: The present invention provides techniques for preventing protocol stalling. A control platform is adapted to generate a predetermined time period, wherein the predetermined time period is reset when an acknowledgement signal is received. The control platform is further adapted to examine stored packets to detect new or negatively acknowledged packets. A transmission platform is adapted to transmit an earliest transmitted packet after the predetermined time period expires when no new or negatively acknowledged packets are detected.

    摘要: The present invention is aimed at techniques for detecting the “partial loss” of an upper layer frame. One technique envisions a detection platform adapted to determine whether a packet is a final packet for a particular upper layer frame. A comparator platform then compares packets received free of transmission errors with variables indicative of whether all received packets in the particular upper layer frame have been received correctly when a final packet is detected. A transmission platform then sends a signal indicative of whether the packets received without transmission errors constitute the particular upper layer frame so that lost packets can be retransmitted quickly.

    摘要: An overload or congestion condition on an access medium (24) of a communication network (22) is indicated by at least one condition that indicates an amount of access attempts on the access medium (24) corresponds to congestion or overload of a capacity of the access medium (24). Example conditions in disclosed embodiments include an occupancy level of the access medium, an average number of access probes associated with successful access attempts, a relationship between received power and interference, an emergency condition and network configuration or maintenance procedures. In a disclosed example, when congestion or overload occurs, at least one technique is implemented to reduce the congestion or overload for stabilizing the access medium. Disclosed example techniques for this include throttling the number of access attempt by reducing the number of users making access attempts or the frequency of user access attempts. Another example technique includes adjusting at least one access medium parameter that will reduce the access attempt traffic.

    摘要: At least a portion of a total spectrum bandwidth of a wireless system may be allocated to each of a plurality of users by assigning at least one unique spreading code to each of the plurality of users. At least two of the plurality of users may have different spectrum capabilities and may transmit simultaneously. Each of the assigned spreading codes may have a different code length. The number and/or the code length of the spreading codes assigned to each user may be indicative of a portion of the total spectrum bandwidth allocated to each user.

    摘要: Methods and systems are provided for improving frame selection in wireless communications networks. During decoding of a frame, a base station generates an error burst representation associated with error bursts and stores the representation within the frame, thus forming an enhanced frame. The base station then transfers the enhanced frame to a network controller. A frame selection unit (“FSU”) within the network controller thereafter applies frame selection to the enhanced frame. The error burst representation can be analyzed to determine the quality of the enhanced frame. A “combined” frame, generated by combining an “acceptable” portion of the enhanced frame and an acceptable portion of a copy of the enhanced frame, can then be generated to substantially eliminate errors. The present frame selection methods and systems enable superior quality frames to be passed on to higher layers in a network's communications protocol (hereafter collectively referred to as “network”).

    摘要: The present invention provides an improved RACH access burst arrangement and frame structure. That is, the invention provides methods and apparatus for supporting more than one access burst length in the UMTS access channel structure. Preferably, two access burst lengths are supported, e.g., 5 ms and 10 ms. Such an arrangement is advantageous in applications where it is beneficial to have fast access latency such as, for example, voice or other forms of real-time traffic. Also, the invention provides methods and apparatus for supporting multiple frame sizes. It is to be appreciated that further enhancement to access latency can be obtained by having the UMTS physical layer support multiple frame sizes. The access burst signal transmitted by a remote terminal over the RACH may be an access request or data packets in the case where the RACH is being utilized for UMTS short message services.

    摘要: In one embodiment, a relationship is determined between radio link protocol (RLP) sequence numbers in received RLP packets and real-time protocol (RTP) sequence numbers in RTP packets decompressed from the received RLP packets. An RTP sequence number associated with a compressed RTP packet is determined based on the determined relationship and at least one of the RLP sequence numbers of the received RLP packet or packets forming the compressed RTP packet. An RTP time stamp may be determined in a similar manner.
