Implementations related to updating channel adaptation parameters are described. In one implementation, an R2T frame, such as an acknowledgment (ACK) frame, is modified to carry a partial bit allocation table (BAT). The R2T frame may be received by a transceiver apparatus and the partial BAT carried in the header or extended header(s) of R2T frame may be used to update a BAT stored in the transceiver. In another implementation, a message frame is modified to carry a partial BAT. The message frame may be received by a transceiver apparatus and the partial BAT used to update a BAT stored in the transceiver. A unique identification number generated by the receiving transceiver apparatus may be used to synchronize BATs stored in two communicating transceivers without necessity of exchanging additional control messages.

Channel adaptation for multicarrier arrangement

A method for wireless communication is described herein. The method may include advertising support by a wireless device for a first bandwidth mode and a second bandwidth mode, wherein the first bandwidth mode utilizes a single channel and the second bandwidth mode utilizes channel bonding between a plurality of channels. The method may also include switching a current bandwidth mode of the wireless device from one of the bandwidth modes to the other of the bandwidth modes and adjusting a number of multiple-input, multiple-output (MIMO) spatial streams supported by the wireless device in response to the switching.

Techniques for supporting multiple bandwidth modes

In an aspect a transceiver is provided. The transceiver may include a plurality of local oscillator (LO) generators configured to generate a plurality of LO signals, respectively, for mixing with one or more communication signals. The transceiver also includes a first synthesizer configured to generate a first reference signal and a second synthesizer configured to generate a second reference signal. The transceiver also includes a distribution circuit. The distribution circuit is configured to switch an input to at least one of the LO generators between the first and second reference signals for tuning each of the at least one of the LO generators between two different LO frequencies and to input to the other ones of the LO generators the first reference signal for tuning each of the other ones of the LO generators to an LO frequency.

A method and apparatus are disclosed for a wireless communication device capable of scanning for radar signals while detecting and/or receiving a wireless communication signal. The wireless communication device may include a plurality of local oscillator synthesizers to allow distinct frequency bands to be used for wireless communication signals and radar detection. In some embodiments, the wireless communication device may include a radar detection physical layer (PHY) circuit to detect the presence of radar signals within a received RF signal. The radar detection PHY may have limited functionality suitable primarily for radar signal analysis and not suitable for processing (decoding) communication signals.
