| 20120136992 | USAGE-SENSITIVE POLICY AND CHARGING CONTROL METHOD, SERVERS, SYSTEMS AND COMPUTER PROGRAMS - In a policy and charging control method carried out by a server including a policy and charging enforcement function (PCEF), identification information for identifying a particular service instance of a particular service type is obtained. When a packet is received, the PCEF determines whether the packet belongs to the particular service instance by using the identification information and by inspection of at least one of Open Systems Interconnection (OSI) layer n control information of the packet, wherein n is an integer equal to or larger than 3, and the packet's payload. If it is determined that the packet belongs to the particular service instance, the PCEF updates a usage parameter representing an accumulated usage associated with the particular service instance. The PCEF then makes available to a policy and charging rules function (PCRF), the usage parameter or information derived therefrom. | 05-31-2012 |
| 20120134327 | SEMI-PERSISTENT RESOURCE ALLOCATION METHOD FOR UPLINK TRANSMISSION IN WIRELESS PACKET DATA SYSTEMS - A wireless telecommunications network supplies a semi-persistent resource that a wireless station can use for special purposes (such as a retransmission of packets for ARQ purposes or a control signal. The semi-persistent resource can be allocated by the system to other terminals if, e.g., a retransmission is not required. Since a retransmission is generally performed in response to a NACK received from a base station, the NACK may itself serve as a token that permits the wireless station to use the semi-persistent allocation. Thus, the technology includes, e.g., a method for resource allocation on a semi-persistent basis and efficient signaling for the usage of such allocation. | 05-31-2012 |

| 20120008563 | Power Backoff for Multi-Carrier Uplink Transmissions - Teachings presented herein provide reduced computational complexity and/or memory requirements for a mobile terminal to determine the power backoff required for a multi-carrier uplink signal. In particular, the mobile terminal determines whether its power headroom falls below a pre-defined power headroom threshold, indicating that it is headroom limited. If so, it5 quantizes power allocated to each carrier of the multi-carrier uplink signal according to a pre-defined quantization policy. In doing so, the mobile terminal thereby reduces the possible configurations that may be selected for the multi-carrier uplink signal. Thus, in one embodiment, the mobile terminal stores the required backoff in a look-up table for only the configurations that may be selected when the mobile terminal is headroom limited. This relieves 10 the memory requirements of the mobile terminal as compared to storing the required backoff for all possible configurations of the multi-carrier uplink signal. | 01-12-2012 |

The service node comprises: a request receiving unit that receives a first user identity that identifies the first user node and a second user identity that identifies the second user node; a determining unit that determines whether a received message includes the first user identity as a destination, or the message includes auxiliary information that corresponds to the first user identity; and a modifying unit that modifies the destination of the message to the second user identity and modifies the source of the message to the first user identity in accordance with the determination result by the determining unit. | 10-06-2011 |
| 20110244915 | SYSTEM AND APPARATUS FOR INTERFERENCE SUPPRESSION USING MACRODIVERSITY IN MOBILE WIRELESS NETWORKS - In a wireless network, plural downlink signals from plural base stations are transmitted to a terminal. The plural downlink signals all carry the same information to the terminal. The terminal provides feedback on the downlink channels. The feedback provides information on the taps of the channels. The amount of information fed back is constrained. Based on the feedback, transmission parameters of the downlink signals are adjusted. The process of transmitting, providing feedback, and adjusting the parameters continue so that the energy of the downlink signal is enhanced at the terminal location and suppressed elsewhere. Beam forming can be used to further suppress the energy signature at locations other than the terminal location. | 10-06-2011 |
