Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may wake up from a sleep mode of a discontinuous reception (DRX) cycle based on receipt of uplink data. The UE may determine if an elapsed time between a prior receipt of one or more reference signals and an uplink transmission to the base station after waking up from the sleep mode is less than a threshold time value. If the elapsed time is less than the threshold time value, the UE may transmit an uplink transmission associated with the received uplink data prior to receiving one or more reference signals that may be used to update transmission parameters for uplink transmissions. If the elapsed time is at or above the threshold value, the UE may wait to receive the one or more reference signals and update the transmission parameters prior to the uplink transmission.

A transmitting device may select a scrambling sequence to use per symbol to reduce variance in a non-linearity parameter for a power amplifier (PA) output between a data symbol and a pilot symbol based on a PA model for at least one pilot symbol or one or more parameters of the model.

If the transmitting device does not receive the capability message from the receiving device or if the capability message indicates the receiving device is not capable of blind estimation, the transmitting device may indicate the selected scrambling sequence to the receiving device. Otherwise, the transmitting device may not indicate the selected scrambling sequence to the receiving device, and the receiving device may blindly estimate the scrambling sequence.

Abstract: This disclosure provides methods, devices and systems for enhanced bandwidth negotiation. Some implementations more specifically relate to request-to-transmit (RTS) and clear-to-send (CTS) frame designs that support bandwidth negotiations over a range of bandwidths achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, a bandwidth negotiation frame (such as a CTS or RTS frame) may be configurable to support bandwidths greater than 160 MHz. In some aspects, the bandwidth negotiation frame may conform to a legacy control frame format. More specifically, one or more bits of a service field associated with the legacy control frame format may be repurposed to carry enhanced bandwidth information. In some aspects, a recipient of a bandwidth negotiation frame may interpret one or more bits of the service field to carry enhanced bandwidth information when the frame is transmitted by a non-legacy transmitting device.

Abstract: An asynchronous medium access control layer scheduler increases efficiency for directional mesh networks by removing extra overhead in the time slots. The efficiency is increased by dividing time slots into sub-slots to allow for a receiving node to be offset by at least one sub-slot from the transmitting node. This enables the scheduler to more efficiently schedule operations for the nodes so that nodes can be performing other functions rather than waiting to receive a transmission or waiting after transmitting a transmission. The sub-slots may be sized to approximate the transmission propagation time or time of flight delay.
