Abstract: A transport block size (TBS) of a first uplink message (RACH Msg3) transmitted on a Physical Uplink Shared Channel (PUSCH) during a random access procedure in a User Equipment (UE) accessing a radio access network may be determined by receiving a pathloss threshold parameter. A downlink pathloss value indicative of radio link conditions between the UE and a base station (eNB) serving the UE is then determined. A smaller value of TBS is selected from a set of TBS values if the determined pathloss value is greater than an operating power level of the UE minus the pathloss threshold parameter. A larger value of TBS is selected if the pathloss value is less than the operating power level of the UE minus the pathloss threshold parameter and the TBS required to transmit the RACH Msg3 exceeds the smaller TBS value.

Abstract: Methods and apparatus are provided for determining acknowledgement/negative acknowledgement (ACK/NACK) resources at a user equipment (UE) in a wireless communication system. Control information is received on a downlink control channel for data transmission and the control information is decoded.

A resource for transmission of an ACK/NACK is determined based on the determined scheduling type of the data channel.

Abstract: A system is proposed to provide handover in a mobile telecommunications environment, particularly applicable to 3GPP networks, which does not increase signalling overhead but minimises user data loss during handover. In the modified system, PDCP SDUs with Sequence numbers are buffered and retransmitted as necessary. At the time of handover, SDUs not received by the user device are forwarded to the target base station for forward transmission to the UE. The handover procedure is designed to minimise packet loss whilst keeping to a minimum the duplication of packet transmission over the air interface.

Abstract: In current approaches to M2M architectures, no interworking application programming interfaces (API's) are exposed to the service layers that are in the local network. Thus, a service layer might not able to make various requests including, for example, that devices be triggered, that the service layer receive notifications when devices are connected to the network, and that the service layer receive notifications when devices are no longer connected to the network. Described herein is a small cell architecture that provides an interworking interface to applications and service layers that reside in the local small cell network. For example, a small cell or eNB may send a notification, for example to a Local Security Capability Exposure Function (L-SCEF) or a core network function, when a UE attaches to or disconnects from a local network.

Abstract: An approach for a dynamic provisioning of multiple RSS engines is provided. In an embodiment, a method comprises monitoring a CPU usage of hardware queues implemented in a plurality of RSS pools, and determining whether a CPU usage of any hardware queue, implemented in a particular RSS pool of the plurality of RSS pools, has increased above a threshold value. In response to determining that a CPU usage of a particular hardware queue, implemented in the particular RSS pool, has increased above the threshold value, it is determined whether the particular RSS pool includes an unused hardware queue (a queue with light CPU usage). If such an unused hardware queue is presented, then an indirection table that is associated with the particular RSS pool is modified to remap one or more data flows from the particular hardware queue to the unused hardware queue.

Abstract: Providing integrated LTE-B network and service management is disclosed. Changes to an LTE or LTE-B network can be propagated in real-time, or near-real-time, to a mapping profile representative of the LTE or LTE-B network.

Abstract: A learning protocol for distributed antenna state selection in directional cognitive small-cell networks is described. Antenna state selection is formulated as a nonstationary multi-armed bandit problem and an effective solution is provided based on the adaptive pursuit method from reinforcement learning. A cognitive small cell testbed, called WARP-TDMAC, provides a useful software-defined radio package to explore the usefulness of compact, electronically reconfigurable antennas in dense small-cell configurations. A practical implementation of the adaptive pursuit method provides a robust distributed antenna state selection protocol for cognitive small-cell networks. Test results confirm that directionality provides significant advantages over omnidirectional transmission which suffers high throughput reduction and complete link outages at above-average jamming or cross-link interference power.
