Abstract: A method for transmitting control information in uplink from a mobile terminal to a base station in a wireless mobile communication system is provided. In the method, when no data to be transmitted to the base station is present in the mobile terminal, Scheduling Request (SR) information and Channel Quality Indicator (CQI) information having a predetermined size or greater are multiplexed together and the multiplexed information is transmitted to the base station through a Physical Uplink Shared CHannel (PUSCH). This method prevents waste of uplink transmission resources while avoiding uplink data transmission delay.

Abstract: A bandwidth management system includes a plurality of queues respectively corresponding to a plurality of zones. An enqueuing module receives network traffic from one or more incoming network interfaces, determines a belonging zone to which the network traffic belongs, and enqueues the network traffic on a queue corresponding to the belonging zone. A dequeuing module selectively dequeues data from the queues and passes the data to one or more outgoing network interfaces. When dequeuing data from the queues the dequeuing module dequeues an amount of data from a selected queue, and the amount of data dequeued from the selected queue is determined according to user load of a zone to which the selected queue corresponds.

The method of performing a random access includes transmitting a random access preamble to a network node and receiving a random access response from the network node, wherein the random access response is received through a first subframe if the random access preamble is a dedicated preamble, and the random access response is received through a second subframe which is different from the first subframe if the random access preamble is a non-dedicated preamble.

Abstract: A network/base station broadcasts an indication to direct a user equipment how to prioritize information for inclusion in an uplink message to be sent on a random access channel RACH. By example one value of the indication directs a user equipment UE to prioritize inter-frequency over intra-frequency neighbor cell measurements for inclusion in the uplink message; and another value (or absence) of the indication directs a UE to prioritize intra-frequency over inter-frequency neighbor cell measurements for inclusion in the uplink message. A UE receiving the broadcast indication constructs the uplink message which includes information that is prioritized in accordance with the indication so as not to exceed a maximum message size.

Abstract: Embodiments are directed towards managing network routes using a centralized service on behalf of a network of a plurality of forwarding devices. The centralized service develops a global view of the network based on information from the forwarding devices. The centralized service computes changes to the routing policy for each of the nodes. The centralized service then generates an operational command schedule that is distributed to the forwarding devices using a “make before break” sequence to ensure that transient black holes do not happen as the new routing policy is being implemented.

Within a multi-user packet, information (e.g., partial address information) related to a recipient group of wireless communication devices (e.g., as few as one wireless communication device or any subset of a number of wireless communication devices, sometimes including all of the wireless communication devices) is emplaced within a PHY (e.g., physical layer) header of such a multi-user packet to be communicated within a multi-user (MU) environment. Such recipient indicating information can be encoded with relatively higher robustness (e.g., lower coding rates, lower ordered modulation, cyclic redundancy check (CRC), etc.) that remaining portions of the multi-user packet. Various portions of the remainder of the multi-user packet may respectively correspond to different wireless communication devices (e.g.

More particularly, the present invention relates to a method for performing processes in which a terminal determines control channel allocation, as well as to an apparatus for the method. The method comprises the following steps: monitoring, on a first carrier, a first search space, containing a control channel candidate set, for control channels having no carrier indication information; and monitoring, on a second carrier, a second search space, containing a control channel candidate set, for control channels having carrier indication information.

Abstract: In one embodiment, a routing table of a router is populated with a plurality of prefixes. One or more performance characteristics of the plurality of prefixes are monitored. The router determines that a need exists to split a selected prefix of the plurality of prefixes. The router determines one or more boundaries upon which to split the selected prefix based on the monitored performance characteristics. The router then injects one or more more-specific prefixes into the routing table, each more-specific prefix referring to a smaller subset of nodes than the selected prefix, to split the selected prefix on the one or more boundaries to create a plurality of split prefixes. The split prefixes are controlled to optimize distribution of traffic.

A method for communications device operations includes determining a hybrid automatic repeat request (HARQ) response for each component carrier (CC) in a set of configured CCs, thereby producing a set of HARQ responses, generating an information vector from the set of HARQ responses, encoding the information vector based on a (n, k) linear block code corresponding to the set of configured CCs, and transmitting the encoded information vector.

Abstract: Exemplary methods and systems may generally be implemented to allow a macro-network base station without access to a GPS reference signal to provide some or all of the functionality for which existing macro-network base stations typically rely on GPS. In a first aspect, an exemplary macro-network base station may determine its location using a location-determination technique that is based upon the angles of arrival of FM radio signals from nearby FM stations. In a second aspect, an exemplary macro-network base station may stabilize its local oscillator by phase-locking its local oscillator to an FM radio signal, and periodically adjusting its local oscillator to account for phase drift of the FM radio signal. And in a third aspect, an exemplary macro-network base station may synchronize its frame-start timing with a nearby base station using a frame-start timing signal that the base station has synchronized to frame transmissions from the nearby base station during a setup routine.
