A terminal apparatus transmits capability information. The capability information includes a first capability parameter, a second capability parameter, and a third capability parameter. The first capability parameter indicates whether the terminal apparatus supports Semi-Persistent Scheduling in a primary cell. The second capability parameter indicates whether the terminal apparatus supports skipping of uplink transmission corresponding to a grant configured for a primary cell in a case that there is no available data for transmission in a buffer of the terminal apparatus. The third capability parameter indicates whether the terminal apparatus supports Semi-Persistent Scheduling in an LAA secondary cell, and whether the terminal apparatus supports skipping of uplink transmission corresponding to a grant configured for an LAA secondary cell in a case that there is no available data for transmission in the buffer of the terminal apparatus.

Channel quality information feedback techniques

Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.

RAN based gateway functions

It is provided a method, comprising binding, for a terminal, at least one of an uplink and a downlink bearer to an IP address based on a gateway context, wherein the gateway context is controlled by a control device; and at least one of buffering and idle mode handling; wherein the buffering is adapted to buffer data for the terminal during hard handover of the terminal and to forward the data to the terminal after the hard handover is completed; the idle mode handling is adapted to forward a packet received for the terminal to a control device if the gateway context does not comprise an identification of a base station to which the terminal is attached.

VOICE SERVICE HANDOVER

A user entity (UE) such as a smartphone is configured to connect to both Wi-Fi and a Long Term Evolution (LTE) cellular network for voice and data services. For voice, the UE supports both Voice over LTE (VoLTE) and Voice over Wi-Fi (VoWiFi). When the UE is connected to VoWiFi and roaming from a first Wi-Fi access point to a second Wi-Fi access point, the UE and Mobility Management Entity in the cellular network carry out a preparatory handover to VoLTE to prevent service loss in the event of an unsuccessful VoWiFi connection from the second Wi-Fi access point.

In order to enable the protection of a system in which an abnormality is detected even while restricting the degradation of availability of a service provided by a base station device, a communication system in an exemplary embodiment has a first server which provides a first service, a second server which provides a second service, and a first base station device communicating with the first and second servers, wherein in the case where the second service has a higher priority than the first service, a communication path between the first base station device and the first server is cut off when an abnormality is detected from the first server.

MESSAGE 1 OF A TWO-STEP RANDOM ACCESS PROCEDURE

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is configured to use a two-step random access channel (RACH) procedure. The two-step RACH procedure may include an uplink request message and a downlink response. The UE may transmit the uplink request message as part of the two-step RACH procedure, and the uplink request message may include a preamble portion that is one of a set of predefined sequences and a payload portion that includes a physical uplink shared channel waveform. The UE may receive the downlink response as part of the two-step RACH procedure and in response to the uplink request message.

Methods and systems for a detecting an intruder near or within a vehicle are disclosed. Specifically, a method to detect and identify a person near or within a vehicle as an authorized or an unauthorized user is provided. In the event an unauthorized user is detected within a vehicle, the system may take a number of actions. In one embodiment, the actions comprise providing notice to one or more authorized users of the vehicle, disabling the vehicle, notifying emergency personnel or police, and emitting a visual or audio alarm.

Support of legacy network elements in small cell system

The present invention addresses apparatuses, methods and computer program product for enabling support of legacy user equipment and legacy network elements in small cell system for LTE and beyond systems. Each small cell uses a unique pair of Physical Cell Identifier and E-UTRAN Cell Global Identifier {PCI, ECGI} in the small cell system. In a handover preparation phase, when an enhanced eNB initiates the handover request procedure, the source eNB includes the pair of {PCI, ECGI} in the handover request message. Upon the reception of the {PCI, ECGI} from the handover request message, the associated eNB determines the target small cell based on the received pair of {PCI, ECGI}.
