Abstract: A user equipment (UE) that performs control signal transmission according to a single-segment subframe format is described. In an aspect, the UE selects a single-segment subframe format as an uplink transmission format for a subframe instead of a multi-segment subframe format. This selection may be based on an indication received by a network node that the single-segment subframe format is to be used for transmission of the one or more control signals. In addition, the UE transmits the one or more control signals on an uplink control channel using the single-segment subframe format.

Abstract: A subscriber issues a message to a resource host to request subscription to multiple resources. This message may indicate identifiers of these resources, event notification criteria for each individual resource, and define cross-resource notification criteria, such as time window type and time window size. The resource host issues cross-resource notifications to the subscriber or its designated notification targets when expected changes on the target resources occur within a time window.

Abstract: Systems and methods of providing a NPRACH preamble in a multefire system are described. A UE configured for multefire NB-IoT or eMTC operation receives, from an eNB, access information that includes a SIB on a narrowband channel of an unlicensed band. Based on the access information, the UE transmits a NPRACH preamble in two or six contiguous uplink subframes. The NPRACH preamble is transmitted in two or six contiguous subframes. When two subframes are used, four symbol groups each having a 266.7 ?s CP and two symbols are transmitted without a gap therebetween. When six subframes are used, four symbol groups each having a 266.7 ?s CP and five symbols are transmitted without a gap therebetween.

Abstract: A radio station (2) transmits or receives, to or from a radio terminal (1) in a second cell (23, 24), a CP message containing a NAS message or an RRC message or both, when a predetermined condition is satisfied. The second cell (23, 24) uses a RAT different from that of the first cell, and is used in addition and subordinate to the first cell. The predetermined condition relates to at least one of: (a) a content or type of the CP message; (b) a type of a signalling radio bearer used to transmit the CP message; (c) a transmission cause of the CP message; and (d) a type of a core network associated with the NAS message. It is thus, for example, possible to contributing to efficient transmission of control plane (CP) messages in a radio architecture that provides interworking of two different Radio Access Technologies (RATs).

Abstract: A system and process are provided for remotely viewing a customer screen image and interacting with the customer's device (desktop, laptop, tablet or smartphone) using a standard web browser. In operation, an agent is provided with an account on a server, and can send a link and/or instructions to the customer to provide the agent with access to the customer device. An application installed on the customer device captures image frames to be shared and divides them into subsections, transmitting to the server only those sections that have changed relative to the previously transmitted frame. The agent's browser retrieves tiles from the server as they change, and displays them for the agent. The system and process enable the agent to obtain system information and remotely control various functions of the customer device when authorized by the customer.
