摘要： In one embodiment, an apparatus includes memory storing instructions and processing circuitry coupled to the memory. The processing circuitry is to implement the instructions to select a resource block group (RBG) size configuration from a set of RBG size configurations based on a bandwidth part (BWP) size. Each RBG size configuration is to indicate RBG sizes associated with respective ranges of BWP sizes, and the RBG sizes are to indicate a number of frequency-domain physical resource blocks (PRBs) for physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) transmissions. The processing circuitry is further to implement the instructions to allocate PRBs for communication between the gNB device and a user equipment (UE) device via the PDSCH or PUSCH transmissions based on the selected RBG size, and to encode downlink control information (DCI) that indicates the allocated PRBs for transmission to the UE device.

摘要： Disclosed herein are integrated circuit (IC) packages, antenna boards, antenna modules, and communication devices (e.g., for millimeter wave communications). For example, in some embodiments, an antenna module may include: a logic die; a radio frequency front-end (RFFE) die in electrical communication with the logic die; and an antenna patch, wherein the RFFE die is closer to the antenna patch than the logic die is to the antenna patch.

摘要： A method of generating channel estimates of a communication channel in an OFDM system includes receiving references symbols from at least one time frequency observation block of a predetermined block size in frequency and time; generating subspace-transformed reference symbols from the received reference symbols; and subspace filtering the subspace-transformed reference symbols to generate a channel estimate for a communication channel target time; wherein a latency between a communication channel time instant of a currently received reference symbol and the communication channel target time is smaller than the observation block size in time.

摘要： This disclosure describes methods, apparatuses, and systems related to signaling for concurrent operation and/or cancellation capabilities for termination of concurrent operations on networks (e.g., NAN, WLAN networks). In some implementations, systems and methods are provided for handling of time blocks that partially overlaps with the concurrent operations.

摘要： Examples provide a method for clock calibration. A wireless communication device includes a first clock and a second clock. The first clock is turned off but the second clock runs during the inactive state of the wireless communication device. A frequency offset of the first clock is measured with respect to a reference frequency based on a signal received from a network. A virtual timer, which is a software-based timer is updated based on the frequency offset. A drift of the second clock is measured over a predetermined time interval based on the virtual timer. The virtual timer is restored based on the drift after wake-up from the inactive state. Alternatively, a clock frequency relation between the first clock and the second clock may be measured and a phase locked loop (PLL) may be controlled based on the measured clock frequency relation.

摘要： An apparatus for interpolation of polar signals in RF transmitters is disclosed. The apparatus comprises an estimation circuit configured to receive an input in-phase (I) quadrature (Q) signal comprising a plurality of input IQ samples having a first sampling rate associated therewith, and determine a selection metric value indicative of a position of an IQ trajectory associated with one or more input IQ samples of the input IQ signal. The apparatus further comprises a selection circuit configured to receive the input IQ signal and the selection metric value; and adaptively provide the input IQ signal to a first interpolation circuit that implements a first interpolation method or to a second interpolation circuit that implements a second, different interpolation method, for generating interpolated polar samples at a second, different sampling rate, from the input IQ signal, based on the selection metric value.

摘要： Methods, apparatus, and computer-readable media are described for notching a 6 GHz channel. A station associates with an access point on a 6 GHz band. A notching pattern indication is decoded from data received from the AP after associating with the AP. A notching region within a channel within the 6 GHz band is determined based on the notching pattern indication. The notching pattern indicates a width of a notching region and a location of the notching region within the channel. The notching region covers bandwidth occupied by an incumbent system within the channel. A physical layer convergence procedure (PLCP) protocol data unit (PPDU) is encoded for transmission on the channel to the AP. The PPDU is encoded to exclude transmission within the notching region.

摘要： Techniques to enable dynamic bandwidth management at the physical layer level while maintaining backwards compatibility in wireless systems is provided. Furthermore, techniques for reducing the occurrence of exposed nodes are provided. A transmitter may transmit a frame including an indication that a PHY layer sub-header defining a bandwidth associated with a channel is present. Furthermore, the transmitter may transmit a third frame after receiving a second frame from a receiver to indicate to legacy stations that the TXOP was successful.
