摘要： To address M2M (Machine to Machine), IoT (Internet of Things), energy management, sensor applications, and the like, low-power Wi-Fi is intended to leverage the mass-market WLAN infrastructure for reliable, consistent, and stable access to Internet and "cloud" services. For IEEE 802.11ax OFDMA modes, even when a device transmits a 2 MHz signal, the device is required to first transmit a legacy preamble at 20 MHz. Transmission of this legacy preamble provides coexistence compatibility with legacy devices. This drastically limits the power savings that can achieved if a narrow band mode is defined which is also able to remove the restriction of first having to transmit the legacy preamble at 20MHz. Thus, mechanisms to allow future LP devices to coexist with legacy devices required.

摘要： Devices and methods performing handover with or without the use of random access channel (RACH). An apparatus of a user equipment (UE) can include processing circuitry configured to decode a configuration message to initiate a RACH-less handover from a source eNB to a target eNB, the configuration message including an uplink grant information and a resource type information. Synchronization information is encoded for transmission to the target eNB using a first uplink resource indicated by the uplink grant information. A second uplink resource on an unlicensed wireless band is selected based on the resource type information. A confirmation message indicating completion of the RACH-less handover is encoded for transmission to the target eNB on the unlicensed wireless band using the second uplink resource.

摘要： Methods, systems, and devices for wireless communication are described. Techniques for communicating between an access point and a mobile device via a low-power radio access technology different than a normal radio access technology used for communication are described. During a first negotiation, it is determined whether the access point and the mobile device are capable of communicating via the low-power radio access technology. During a second negotiation, communication parameters for using the low-power radio access technology are agreed upon between the access point and the mobile device. Communications via the low-power radio access technology may be made while the mobile device is in a low-power mode.

摘要： Certain aspects of the present disclosure generally relate to wireless communications and, more specifically, to power savings based on distributed enhanced machine type communication (eMTC) functions, for example, between an applications processor and a modem of an eMTC device. An example method generally includes entering a power saving mode (PSM), wherein entering the PSM includes performing a first power collapse of an applications processor of the wireless node and a modem of the wireless node into a low power state; exiting the PSM at expiry of a wake-up timer, wherein exiting the PSM includes waking up the applications processor and the modem from the low power state to an active power state; and in response to exiting the PSM, performing a second power collapse of the applications processor into the low power state while the modem operates in the active power state.

摘要： Cluster management techniques for wireless data links are described. According to some such techniques, a wireless communication device may maintain proximity information for consideration in conjunction with assigning NAN data links to NAN data clusters. In some embodiments, a wireless communication device may store proximity information for a given NAN data link in an NDL attribute associated with that NAN data link, and may store proximity information for a given NAN data cluster in an NDC attribute associated with that NAN data cluster. In various embodiments, two wireless communication devices may utilize/consider such proximity information in conjunction with assigning a newly-created NAN data link to a NAN data cluster. In some embodiments, two wireless communication devices may utilize/consider such proximity information in conjunction with transferring an extant NAN data link from one NAN data cluster to another NAN data cluster.

摘要： Systems, methods, and apparatuses for dynamic delivery traffic indication message (DTIM) implementations in a wireless communications network are described. In various examples, an access point (AP) may adjust a DTIM period over time based on various criteria, and indicate the adjustment of the DTIM period to stations being served by the AP. A station may adjust its listening period for DTIMs in response to the indication, and update the listening period based on subsequent indications. By adjusting the DTIM period over time, a wireless communications system may more effectively balance performance considerations including latency, power consumption, and synchronization associated with broadcast and/or multicast communications.
