    摘要: Data communication includes an estimate of packet error rate that is useful, for example, when there is insufficient data transmission to provide a direct measurement of packet error rate. At least one pilot channel output provides a basis to determine an estimated packet error rate. One example includes using a pilot channel ratio of an energy-per-chip to a noise spectrum density. Another example includes using a pilot symbol error rate from the pilot channel as the basis for determining the traffic channel packet error rate.

    摘要: In one embodiment, a transmission resource for transmitting data from a number of applications in a multiple carrier communication system is managed. In this embodiment, an aggregate transmission resource available to the number of applications is determined, and the determined aggregated transmission resource is distributed to each carrier based on a load on each carrier. In another embodiment a potential transmission resource for each application on each carrier is determined, and a carrier transmission resource for each carrier is determined based on the determined potential transmission resource for each application on the carrier. Data from at least one of the applications is assigned to at least one of the carriers based on the transmission resource distributed to or determined for the carrier, and the assigned data is transmitted on the carrier.

    摘要: In a Universal Mobile Telecommunications System (UMTS) based wireless system, a channelization code-tree is partitioned into two sets: a permanent set and shared a shared set. Those codes in the permanent set are assigned to low data rate users for the duration of a session, or connection. Those codes in the shared set are assigned to high data rate users on a frame-by-frame basis using a downlink shared (DSCH) channel. The partition boundary between the permanent set and the shared set can be dynamically shifted based on traffic conditions.

    摘要: The present invention provides a method for use in a UMTS receiver of detecting a signal transmitted by a UMTS transmitter which includes determining whether the signal is greater than or equal to at least a first power threshold value when the signal is below an initial detection threshold value, and informing the transmitter when the signal is greater than or equal to the first power threshold value such that the transmitter can increase a signal strength of the signal by a first predetermined amount and re-transmit. In another aspect of the invention, a method for use in a UMTS transmitter of power ramping a signal transmitted by the transmitter and received by a UMTS receiver includes increasing a signal strength of the signal by a first predetermined amount when informed by the receiver that the signal is greater than or equal to a first power threshold value but below an initial detection threshold value, and re-transmitting the signal.

    摘要: System, methods, and networks are disclosed that allow base station systems of a wireless communication network to transmit outgoing traffic over a packet backhaul network to multiple routing elements on the MSC side of the network. A base station system described herein identifies a primary routing element and a backup routing element. The primary routing element is the device to which the base station system transmits outgoing traffic under normal operation, and the backup routing element is an alternate to the primary routing element. To transmit traffic over the packet backhaul network, the base station system monitors the availability of the primary routing element. If the primary routing element is available, then the base station system transmits outgoing traffic over the packet backhaul network to the primary routing element. If unavailable, then the base station system transmits outgoing traffic over the packet backhaul network to the backup routing element.

    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: 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.
