In one embodiment, whether packet loss of link layer packets at a receiver has exceeded a lost threshold is detected. Feedback is sent to a transmitter indicating that a header compressor, for compressing higher layer packets at the transmitter, should send a less compressed header if the packet loss of the link layer packets has exceeded the lost threshold. The higher layer packets are at a higher layer than the link layer and are formed by the link layer packets.

In one embodiment of a method of managing transmission delay in a wireless communication system, a length of time over which a mobile station is permitted to re-transmit a packet or portion of a packet over a channel is controlled such that the length of time depends on at least one of a position of the mobile station, a temporal fading characteristic of the mobile station, and a radio frequency characteristic of the channel.

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.

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.

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.

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.

In the method of flow control, a flow control message, requesting more data, is sent from a first communication device based on an amount of data output by the first communication device and an available data storage capacity of the first communication device.

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.
