An apparatus (18) and method (100) provide RLP data checking. The apparatus (10) includes a frame serialization stage (20) and a bad frame filter (22) that detects possible bad frames and reclassifies these bad frames as erasures. In this manner, bad frame data are not passed to the RLP layer (16), and unnecessary resetting and resynchronization steps are avoided.

Retransmissions of NAK'd frames takes place utilizing a retransmission channel (103-105). In particular, NAK'd frames are retransmitted to requesting remote units (113-115) on a channel (103-105) differing from the channel (109) in which they were originally broadcast to the remote units (113-115). Because retransmission of poorly-received frames occurs utilizing a channel that differs from the downlink multicast channel, the downlink transmission rate of the downlink channel is not reduced when retransmission needs to take place. This greatly improves data transmission to those units not requesting retransmission of data.

To address the need for an interference-efficient method and apparatus to provide CDMA services, embodiments of the present invention adjust the outer loop frame error rate (FER) target on the forward and reverse links (110-113) while providing communication services to remote units (101-102). At times during a service when a link is conveying primarily “empty” eighth rate frames, the FER target for that link is increased. This improves system capacity by effectively reducing the power needed to transmit such frames and thereby reducing the resultant interference.

Rate assignment circuitry (102) detects when a data transmission begins and originally assigns an Orthogonal Variable Spreading Factor (OVSF) code corresponding to low data rate. Over time, a base station controller (101) determines when an OVSF code and/or a repetition rate should be changed (i.e., data rate increased or decreased). The OVSF code and/or the repetition rate is changed in order to gradually increase the data rate, up to a maximum allowable data rate. Once data transmission ceases for a period of time the OVSF code and/or the repetition rate is changed in order to gradually decrease the data rate, down to a lowest allowable data rate.

A method for paging a mobile station where the mobile station (208-212) may be in a dormant state is described. The method begins by sending a first paging message (302) in a first zone (214) of a given area to a selected mobile station wherein the first paging message is sent at the beginning of a paging interval (300). A base station (202-206) then receives a response to the paging message when the mobile station is in the first zone. When the response to the first paging message is not received, a second paging message (306) is sent in a second zone (216) of the given area. The second paging message is sent at a first offset (308) from the sending of the first paging message wherein this first offset occurs less than one paging interval after the sending of the first page message.
摘要:
A method and an apparatus that includes establishing a link (106) between a first node (102) and a second node (104) in a wireless communication network (100). The method continues by setting a discontinuous receive (DRX) transmission mode cycle for the link wherein the DRX cycle includes an on duration (202) followed by an off cycle (204). The duration of the on duration on a downlink is adjusted (610) based on a function of the availability of a channel quality indicator (CQI) channel used on the link.

Disclosed is a method for providing power control using idle-mode user equipment attached to a cell in a wireless communication system. First and second higher power level thresholds for signal transmissions of a cell are defined, wherein the first power level has a defined offset higher than a minimum required power level, and wherein the first and second power level thresholds define an operating power band therebetween. The user equipment measures a signal transmission power level. If the idle-mode user equipment determines that the signal transmission power level falls outside of the operating power band, then a message is sent to affect a change in signal transmission power level.

A method and apparatus for optimizing the mobile media received by a mobile device is disclosed. The apparatus operates with a radio access network, a mobile device operating in the radio access network, and a media server providing mobile media data to the mobile device wherein the mobile device connects to the media server using the radio access network. The apparatus includes a optimization application server coupled to the radio access network. The optimization application server includes positioning indexed performance information based on the positioning information and performance of a plurality of mobile devices operating in the radio access network. The optimization application server triggers adjustments to a parameter at least one of the radio access network, the mobile device and the media server by comparing the location of the mobile device in the radio access network to the optimization application server and sending a message to the radio access network to adjust the parameter.
