摘要： Methods and apparatus for implementing a wireless communication transceiver having receive path performance diversity. The transceiver implements a plurality of signal paths that can be configured as diversity receive paths. Each of the plurality of signal paths includes a distinct RF filter. Each RF filter can be configured to provide a distinct jammer rejection profile. Each receive path also includes a jammer detector, that can be a multiple level jammer detector. Each jammer detector operates to control a level of processing gain applied to the signals in its receive path. The multiple gain scaled receive signals can be combined in a coherent combiner before being routed for further processing.PATENT

摘要： Methods and apparatus for reducing transmit emissions are described herein. The transmit out of band emissions in an adjacent band can be reduced while complying with existing wireless communication standards through utilization of one or more of reduced transmit bandwidth, transmit operating band offset, and channel index remapping. The transceiver can support a receive operating band that is substantially adjacent to a band edge. The transmit operating band can be offset from an adjacent frequency band, and can use a narrower operating band than is supported by the receiver. The transmit baseband signal can have a reduced bandwidth to reduce the amount of noise. The frequency offset can introduce a larger transition band between the transmit operating band edges and the adjacent frequency band of interest. The transceiver can remap channel assignments to compensate for the frequency offset such that the frequency offset introduced in the transmitter is transparent to channel allocation.

摘要： Systems and methods of pre-allocating identifiers to wireless devices for use in requesting resources over a random access channel are described. A wireless communication system includes a random access channel over which wireless devices can anonymously send requests for resources. The base stations receiving and processing the anonymous requests reduces the probability of random access channel collisions and conserves the resources needed to support the anonymous requests by pre-allocating one or more codes to select wireless devices. The wireless devices having the pre-allocated codes can transmit a particular code over the random access channel as a request for resources that uniquely identifies the requester.

摘要： Automatic gain control (AGC) methods and apparatus that implement a dynamically variable AGC setpoint. The variable AGC setpoint can be determined based in part on the type of modulation used to convey information to the receiver. The AGC setpoint can be set higher than a nominal setpoint for higher order modulation types and can be lower than the nominal setpoint for low order modulation types. The manner in which gain is adjusted can also depend on the modulation type. The gains can be increased according to a front to back priority. The gains can be decreased in a priority that is based on the modulation type. For lower order modulation types, the gain controller can decrease gain according to a back to front priority. For higher order modulation types, the gain controller can maintain linearity of front end amplifiers prior to decreasing gain according to a back to front priority.

摘要： A mechanism is provided to allow an HARQ retransmission to more closely match the receiver's need for energy with the additional energy sent over the wireless link. In one aspect, the receiver sends the transmitter qualitative feedback which indicates to the transmitter an approximate amount of additional energy that the receiver needs to successfully decode the transmission.

摘要： Methods and apparatus for identifying a subscriber station which is in motion, determining a mobility metric indicative of a level of mobility of the subscriber station and varying or updating one or more operating parameters based on the mobility metric. An apparatus can determine a measure of mobility based on one or a combination of a plurality of factors, such as variations in signal strength, variations in a channel estimate, or variations in phase or frequency of a particular signal or signal component. The one or more measures of mobility can be combined to form a single measure of mobility, the measure of mobility can be quantized to a predetermined number of mobility levels and one or more operating parameters can be varied or adjusted based on the mobility level.

摘要： Methods and apparatus for implementing a wireless communication transceiver having receive path performance diversity. The transceiver implements a plurality of signal paths that can be configured as space diversity receive paths. Each of the plurality of signal paths includes a distinct RF filter. Each RF filter can be configured to provide a distinct frequency response, and in particular, a distinct jammer rejection profile. One of the RF filters can be configured to provide substantially no in-band jammer rejection. Each additional distinct RF filter can be configured to reject at least one distinct in-band jammer frequency or band of frequencies. A diversity receiver coherently combines the path performance diverse signals from each filter output. A transmitter can time division duplex transmit communications over at least a subset of the signal paths and their associated RF filters.

摘要： Methods and apparatus for control of uplink resource allocation and undesirable transmit emissions from a wireless transceiver in a frequency division duplex (FDD) or hybrid frequency division duplex (H-FDD) wireless system. The bandwidths spanned by the receive band and the transmit band may be symmetric or asymmetric. Additionally, each of the receive band or the transmit band may be contiguous or may be an aggregate of multiple discontinuous frequency bands. The wireless transceiver can control undesirable transmit emissions from occurring in a predetermined frequency band by using an offset LO frequency and restricting transmit signals to frequencies away from the predetermined frequency band. Alternatively, in an asymmetric FDD system where a receive band is larger than a transmit band, the transceiver can limit transmit signal allocation to the transmit band. The transceiver can further limit out of band transmit emissions using an offset LO frequency.
