Abstract:
Various embodiments are generally directed to techniques for channel state determination, such as, for instance, determining one or more channel state parameters for a wireless communication channel between a user equipment (UE) and a base station in a mobile network. Some embodiments are particularly directed to a radio access network (RAN) control system that determines one or more channel state parameters for wireless communication channels in a RAN portion of a mobile network based on propagation data in a channel state base (CSB) database. For example, propagation behavior of a wireless communication channel between a UE and a base station may be calculated by the radio access KSPCS based, at least in part, on propagation data in the CSB database and a physical location of the UE.
Abstract:
Machines (110, 112, 114, 116, 118) or networked devices (102, 104, 106,108) such as internet of things, loT, devices operate to generate an unlicensed narrowband, U-NB, loT communication based on time domain multiple carrier aggregation operations with component carriers. These component carriers can comprise a component carrier that is anchored to a long term evolution, LTE, licensed band, or entirely comprise unlicensed carrier components that are unanchored to the LTE component carrier in a standalone configuration. Communication circuitry such as a radio frequency interface can transmit the U-NB loT communication in standalone communications over a low power loT network in an unlicensed band.
Abstract:
Methods, systems, and storage media are provided for user equipment (UE) that supports enhanced coverage and may operate with a voice centric usage setting or a data centric usage setting. When the UE's usage setting is set to voice centric, the UE may not operate in coverage enhancement (CE) mode B. When the UE's usage setting is set to data centric, then the UE may operate in CE mode B. The UE may indicate the UE's usage setting in an Attach or Tracking Area Update (TAU) request message, and a mobility management entity (MME) may indicate to an evolved NodeB that CE mode B is restricted or not restricted based on the usage setting. Other embodiments may be described and/or claimed.
Abstract:
A communication terminal is described comprising a transceiver configured to support radio communication with a cellular radio communication network via a first frequency band using a first bandwidth and a controller configured to control the transceiver to directly communicate with another communication terminal via a second frequency band using a second bandwidth, wherein the second frequency band is located in a spectrum which is license free.
Abstract:
Systems and methods of protecting key frames are generally described. A device detects the key frame based on packet inspection of a protocol header or payload field, a payload size, or a message transmitted between protocol layers. The modulation scheme, coding rate or number of maximum retransmissions is dependent on the frame type. The presence of the key frame may be indicated in a DCI that contains parameters that correspond to whether the key frame is to be encoded in a transparent or non-transparent manner, or which protection to use when the key frame is to be transmitted, or in a BSR, a data volume indication or a MAC Control Element. An uplink grant provides increased robustness for transmission of the key frame compared to robustness of an uplink grant for transmission of a normal frame.

A communication terminal is described comprising a transceiver configured to support radio synchronization, discovery and communication with a cellular radio communication network via a first frequency band using a first bandwidth and a controller configured to control the transceiver to directly communicate with another communication terminal via a second frequency band using a second bandwidth, wherein the second frequency band is located in a spectrum which is license free.
Abstract:
Machines or networked devices such as internet of things (IoT) devices operate to generate an IoT communication based on a number of standards. Enabling IoT devices to operate emergency communications in SOS or emergency distress situations can be done with various techniques and components that increase / enhance the coverage for a period of time. Thus, non-delay sensitive devices, like IoT devise, can be dynamically enabled to support delay-sensitive applications such as Voice over the Internet Protocol (VoIP) or long term evolution (VoLTE) based applications. Further, fallback operations can be generated based on the geography, the communication channel condition, network or specific enhanced coverage obtainable so that at least some human interaction for addressing such emergency situations can occur.
Abstract:
Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods for communication are generally described herein. The UE may compress network protocol headers in accordance with a robust header compression (RoHC), the network protocol headers corresponding to a sequence of voice packets. The UE may transmit a sequence of packet data convergence protocol (PDCP) packets that are based on an encoding of the voice packets and the corresponding compressed network protocol headers in accordance with a predetermined redundancy rate per PDCP packet. The UE may determine that the RoHC is to be resynchronized, and may transmit a resynchronization PDCP packet to resynchronize the RoHC. The resynchronization PDCP packet may be based on a network protocol header without the compression of the RoHC.
