摘要： A baseband processing module includes an RX interface, a rake receiver combiner module, and may include additional components. The RX interface receives the baseband signals from an RF front end and creates baseband RX signal samples there from. The rake receiver combiner module includes control logic, an input buffer, a rake despreader module, and an output buffer. The rake despreader module is operable to despread the baseband RX signal samples in a time divided fashion to produce channel symbols including pilot channel symbols and physical channel symbols.

摘要： A method to adapt channel quality indicator (CQI) reports from user equipment (UE) is provided. This involves first determining the presence of a high-speed shared control channel (HS-SCCH) signal. An estimated signal to noise ratio (SNR) is also determined. Next an SNR correction based on the presence or lack thereof of the HS-SCCH signal and the CRC checks for HS-SCCH and HS-DSCH signals are determined and applied to the estimated SNR. The CQI report is then generated based on the corrected estimated SNR. This CQI report which takes into account a corrected estimated SNR may then be used to adjust the HS-SCCH signal in an HSDPA telephony system.

摘要： A method and system to determine when a wireless terminal has been paged by a servicing base station. An encoded paging burst is received on a paging channel and then decoded to produce a decoded paging burst. The decoded paging burst is processed to determine if it is a null page. When the encoded paging burst is a null page, it is processed to produce a null page pattern. The wireless terminal may then enter a sleep mode or reduced functionality mode for a predetermined period of time. The wireless terminal awakes from the sleep mode to receive additional encoded paging bursts. Processing the additional encoded paging bursts produces a processed encoded paging burst, which is compared to the null page pattern. When compared favorably, the encoded paging burst is considered a null page, allowing the wireless terminal to re-enter the sleep mode without fully decoding the paging burst.

摘要： A system for implementing Incremental Redundancy (IR) operations in a wireless receiver includes a baseband processor, an equalizer, a system processor, and an IR processing module. The baseband processor receives an analog signal corresponding to a data block and samples the analog signal to produce samples. The equalizer receives the samples from the baseband processor, equalizes the samples, and produces soft decision bits corresponding to the data block. The equalizer may be implemented as a distinct processing component or may be performed by the baseband processor or system processor. The system processor receives at least the soft decision bits and initiates IR operations. The IR processing module receives the soft decision bits of the data block and performs IR operations on the data block in an attempt to correctly decode a corresponding data block.

摘要： A method to perform DC compensation on a Radio Frequency (RF) burst transmitted between a servicing base station and a wireless terminal in a cellular wireless communication system that first receives the RF burst modulated according to either a first or second modulation format. Samples from the RF burst, or taken from the training sequence, are produced and averaged to produce a DC offset estimate. The DC offset estimate is then subtracted from each of the samples. The modulation format of RF burst may then be identified from the samples. Depending on the identified modulation format, the DC offset estimate may be re-added to the samples when a particular modulation format is identified as the modulation format of the RF burst. This decision is made based on how well various components within the wireless terminal perform DC offset compensation.

摘要： An arrangement where, in addition to the control channels that are used to set up sessions, there is a logically and physically separate and independent set of control channels that can be used as session control channels. Illustratively, the physical GSM frame arrangement that employs 8 logical slots is used, with one slot both in the uplink and downlink dedicated to these separate control channels. In the downlink, such a control channel provides channel grant information, requests to make and transmit power measurements, poll mobile units, etc. In the uplink, such a control channel can be used to request access to a traffic channel, to report on power measurements, to request special hand-off handling, to respond to polling, etc. Because the uplink session control channel does not need to carry a significant amount of information, the GSM slot can be divided into minislots, with each minislot constituting a session control channel for a group of mobile units.

摘要： A method for adaptively switching between the WS and S authentication schemes is based on the customer's usage. A first preferred embodiment provides a 2n-1 state automaton (where n>1), which switches from the WS Scheme to the S Scheme when the automaton passes from state n-1 to state n, and vice versa. At each new registration, the automaton increases one state if more than 1 call was made (i.e., incoming or outgoing) during the cycle; decreases one state if no calls were made during the cycle; and remains the same if 1 call was made during the cycle. The value of n is preferably determined by the PSP based on customer usage. A second preferred embodiment begins each new cycle with the WS Scheme, and will switch to the S Scheme if a call is made during the registration.

摘要： In a TDM/TDMA portable radio communications system, the modulated RF signal transmitted by a portable handset unit is amplified for uplink transmission to a port by an adaptive class AB power amplifier. A class AB amplifier provides the necessary amplification for the low power levels to be output by the portable units, but must be biased just slightly "on" with no signal input for required maximum efficiency and linearity. In order to maintain the amplifier at a proper bias level over changing temperature conditions and free from the effects of device aging and device-to-device variations, the drain current of the amplifier is monitored each frame outside the burst interval in which the portable is transmitting and thus when no signal is present at its input. The drain current is then controlled by adjusting the gate voltage to compensate for any variations.
