Abstract:
Gathering tenant usage data of server resources. A method includes a server in a cluster providing server resources for one or more tenants of the server. Data is stored in a local usage cache at the server. The data characterizes the resources provided to the one or more tenants of the server. At the server, data stored in the local usage cache is aggregated on a tenant basis, such that data is aggregated for given tenants. The aggregated data is sent to a distributed cache. At the server, aggregated data from other servers in the cluster is received from the distributed cache. The aggregated data from other servers in the cluster is globally aggregated and stored at an aggregated usage cache at the server in the globally aggregated form.
Abstract:
The present disclosure provides methods and apparatuses for improved Iub link congestion management based on a dynamic scaling of flow control request message transmission in multiflow wireless environments. For example, in an aspect, methods and apparatuses are provided for receiving, at a NodeB, a data request from one or more user equipment (UE), wherein each data request corresponds to a flow and the one or more UE is served by a plurality of NodeBs, generating a flow control request corresponding to each flow in response to each data request, and sending each flow control request to a radio network controller (RNC). Thereafter, a Node B may receive data in response to each flow control request, determine a congestion state based on a downlink delay from the RNC detected in the received data, and scale a subsequent one or more flow control requests based on the determined congestion state.
Abstract:
A method operable at a user equipment configured for wireless communication over a dual-frequency, dual-cell network is disclosed includes a primary carrier and a secondary carrier. The method includes maintaining an active set corresponding to the primary carrier; maintaining a virtual active set corresponding to the secondary carrier; and transmitting a control signal including a virtual mobility event corresponding to a change in the virtual active set. An apparatus for performing the method is also disclosed.
Abstract:
A method for wireless communications is provided. The method includes generating two or more uplink carrier signals across a wireless network and generating at least one active signal set for the wireless network. The method also includes generating one or more secondary active signal sets in accordance with the two or more uplink carrier signals to facilitate communications across the wireless network.
Abstract:
A method for sending an uplink order to active set base stations is disclosed. A new mode of operation for a wireless communication device is determined. A transmission is sent on an uplink control channel to active set base stations that indicates the new mode. The transmission from the wireless communication device is received on the E-DPCCH. It is determined if the transmission is an uplink order. The new mode of operation is transitioned to. Subsequent transmissions from the wireless communication device are interpreted using the new mode of operation if the transmission is an uplink order.
Abstract:
A method and apparatus for wireless communication may provide a multi-link PDCP sublayer in a radio network controller capable of allocating PDCP PDUs among a plurality of RLC entities for use in a multi-point HSDPA network. Some aspects of the disclosure address issues relating to out-of-order delivery of the PDCP PDUs to a UE, such as unnecessary retransmissions. That is, the disclosed multi-link PDCP may be capable of distinguishing between sequence number gaps that are caused by physical layer transmission failures and those caused merely by skew.
Abstract:
A method of communicating speech comprising time-warping a residual low band speech signal to an expanded or compressed version of the residual low band speech signal, time-warping a high band speech signal to an expanded or compressed version of the high band speech signal, and merging the time-warped low band and high band speech signals to give an entire time-warped speech signal. In the low band, the residual low band speech signal is synthesized after time-warping of the residual low band signal while in the high band, an unwarped high band signal is synthesized before time-warping of the high band speech signal. The method may further comprise classifying speech segments and encoding the speech segments. The encoding of the speech segments may be one of code-excited linear prediction, noise-excited linear prediction or ⅛ frame (silence) coding.
Abstract:
A method for using a flexible size radio link control (RLC) protocol data unit (PDU) on an uplink is described. A request for an RLC PDU is received from a medium access control (MAC) layer. Radio conditions for a first uplink carrier and a second uplink carrier are determined. A size of the RLC PDU is selected based on the radio conditions. The RLC PDU is generated. The RLC PDU is sent to the MAC layer.
Abstract:
A system and method enable handover from a DC-HSUPA-capable node in a cellular wireless network to a non-DC-HSUPA-capable node. According to various aspects of the present disclosure, a handover may implement a legacy serving cell change procedure or an enhanced serving cell change procedure. In either case, signaling from the network to user equipment includes information to enable the user equipment to change or remove an Active Set when undergoing a handover from a cell with two uplink carriers and accordingly two Active Sets, to a cell with one uplink carrier and accordingly one Active Set.
Abstract:
Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switch communications. The de-jitter buffer methods and apparatus presented avoid playback of underflows while balancing end-to-end delay. In one example, the de-jitter buffer is recalculated at the beginning of each talkspurt. In another example, talkspurt packets are compressed upon receipt of all remaining packets.
