摘要： For example, a wireless communication device may be configured to generate, transmit, receive and/or process one or more transmissions of an Extra Range (ER) Physical layer (PHY) Protocol Data Unit (PPDU), which may be configured to be decodable by ER wireless communication stations (STAs). For example, the ER PPDU may include an ER preamble. For example, the ER preamble may be configured to include an ER STF (ER-STF), an ER LTF (ER-LTF) after the ER-STF, and an ER Signal (ER-SIG) field after the ER-LTF. In one example, the ER PPDU may include a non-ER preamble, which may be configured to be decodable by non-ER STAs, which may not be capable of decoding the ER preamble.

摘要： This disclosure describes systems, methods, and devices related to wake-up frame indication. A device may determine a wake up receiver (WUR) wake-up frame to be sent to a first station device of one or more station devices. The device may determine one or more indications associated with the first station device, wherein the one or more indications indicate to the first station device, one or more actions to be taken by the first station device after waking up a primary connectivity radio (PCR) of the first station device. The device may cause a medium access control (MAC) layer to encode the WUR wake-up frame with the one or more indications associated with the first station device. The device may cause to send the WUR wake-up frame to the first station device using a physical layer (PHY).

摘要： Embodiments of the disclosure relate to operational association between communication devices in the presence of a link-budget imbalance between an upstream link and a downstream link at one of the communication devices. The association relies on a request for a narrowband resource block sent from the communication device having the link-budget imbalance to a remote communication device that can schedule and/or allocate the narrowband resource block. The request can be modulated according to an on-off keying modulation scheme or can be encoded according to a multi-repetition encoding scheme. In response to the narrowband resource block being allocated, an association request can be sent to the remote communication device in the narrowband resource block.

摘要： Embodiments of the disclosure provide auto-detection in wireless telecommunications. Certain embodiments provide or otherwise implement a specific sequence of bits and/or symbols for auto-detection. The specific sequence of bits can be embodied in or can include output codebits from an encoder in a communication device that can send a wireless transmission including the specific sequence. In one embodiment, the encoder can compute or otherwise generate cyclic redundancy checks (CRCs) or other types of validation checks at the communication device. The specific sequence can be determined using the payload of a packet frame. Both the manner in which the specific sequence is generated and the temporal order in which the specific sequence is received relative to other payload in the packet frame can provide specificity to the sequence.
