Abstract: Techniques provide additional Hybrid-ARQ indication resources for LTE TDD subframes that are normally without conventional LTE PHICH resources or that have too few LTE PHICH resources. In some embodiments, a modified PHICH is created using unused REGs in the control region of the downlink subframe. In others, a modified PHICH resides within the resources of an AL=1 PDCCH, and is formed using encoding and modulation processes that differ from normal PDCCH processing. In other embodiments, the PUSCH HARQ feedback bits are carried by a conventional LTE PDCCH, which is distinguished from other PDCCHs by scrambling it with a new type of RNTI: HARQ indicator Radio-network temporary identifier (HI-RNTI). In still other embodiments, the modulation symbols of PHICH are then placed on top of those normally reserved for PDCCHs. For such overlapped radio resources, the modulation symbols from the modified PHICH will replace those from normal PDCCHs for transmission.

Abstract: A method, apparatus, computer program product, and processing system provide for dynamic selection of a secondary serving cell among various available secondary serving cells, be they in the same frequency as the primary serving cell (as in SFDC-HSDPA), in a different frequency but in the same band as the primary serving cell (as in DC-HSDPA), or in a different band from the primary serving cell (as in DB-DC-HSDPA). Here, the UE may be preconfigured for each of the available secondary serving cells, and may receive a configuration message to select between one of them based on factors such UE battery consumption, CQIs corresponding to the available secondary serving cells, loading of the secondary serving cells, or UE power headroom limitations. Thus, an advanced UE capable of receiving the plurality of technologies may benefit from dynamically selecting the best available secondary serving cell in accordance with the factors.

Abstract: A wireless device may compute transmission power of an uplink packet employing a first parameter calculated by accumulation of an initial value and at least one power control value corresponding to a sequence of subframes. The sequence of subframes starts from an initial subframe and ends with the first subframe. The initial subframe is identified by the most recent subframe before the first subframe with one of the following events: a predefined transmit power parameter value is updated by higher layers; and a random access response is received corresponding to a transmitted random access preamble on a secondary cell.

Abstract: A first node that transmits TCP packets to and receives TCP packets from a second node splits a target TCP packet throughput across multiple consecutive time slots, each slot having a target throughput value. If a current slot's achieved throughput value does not match the current slot's target throughput value, the target throughput value for the current slot and/or a subsequent slot is adjusted. Transmit throughput from the first node to the second node is controlled by transmitting TCP packets from the first node to the second node according to a target throughput value for the current slot. Receive throughput from the second node to the first node is controlled by dynamically calculating an advertised receive window size according to a target throughput value for the current slot and communicating the advertised receive window size to the second node.

Abstract: The different switch modules making up a distributed virtual switch may route configuration commands for hardware resources to different modules within the distributed switch using a distribution and routing layer. At least one of the switch modules maintains a routing table that defines which switch modules are responsible for which hardware resources. The switch module uses the routing tables to forward the commands on the distribution and routing layer to the responsible switch module which then ensures that the relevant hardware resources are configured.

Abstract: To prevent buffer overflow, a receiving entity may use credits to control the total amount of packets any single transmitting entity can forward. Once the assigned credits are spent, the transmitting entity cannot send data portions to the receiving entity until additional credits are provided. However, the logic in the receiving entity may be designed to manage a maximum number of credits that is less than the capacity of the buffer in the transmitting entity. For example, the receiving entity is designed to manage a maximum of eight credits but the buffer has room for twelve data portions. To use the buffer efficiently, the transmitting entity may identify when extra buffer storage is available and provide additional credits. In addition, the transmitting entity may control when the credits are provided such that the receiving entity is not allocated more credits that it was designed to manage.

Abstract: A virtual chassis system includes a plurality of network nodes configured with a master virtual chassis address. The network nodes are connected by virtual fabric link (VFLs) that provide a connection for exchange of data packets between the network nodes. The data packets include source MAC addresses and associated hardware device information, such as source chassis ID, source network interface identifier and source port identifier information. The network nodes use this information to maintain synchronized MAC address tables for forwarding of data packets in the virtual chassis system. One or more control protocols in the network node are used for topology discovery, master network node election, generation of routing tables, health monitoring and other functions.

The communication system implements at least a first radio access technology via a first base station and a second radio access technology via a second base station. The first and second radio access technologies differ from one another. Information relating to an interference signal received at the first base station via the first radio access technology is received at the second base station from a first device associated with the first base station, At a second device associated with the second base station, an interfering user equipment accessing the second base station via the second radio access technology is identified. The identification is based on the information received from the first device associated with the first base station. Interference caused by the identified interfering user equipment is suppressed by the second base station.

Abstract: A network node receives a Session Initiation Protocol (SIP) or H.323 signaling packet associated with data traffic, and determines if the data traffic originated from a source node or source network as Voice over Internet Protocol (VoIP) traffic. The network node tags a header of the SIP or H.323 signaling packet with a tag that identifies the data traffic as a VoIP originated call based on the determination, and sends the tagged SIP or H.323 signaling packet towards a destination. The network node further sends data identifying the data traffic as a VoIP originated call to an administrative system for at least one of call billing, rating, settlement or taxation purposes.
