  • Patent number: 8902833
    Abstract: A method and apparatus for wireless communication may provide an RLC reset procedure tailored for a multipoint HSDPA system utilizing a plurality of disparate Node Bs to provide an RLC flow from an RNC to a UE. Some aspects of the disclosure provide for a flush request to be provided to each of a plurality of Node Bs utilized as serving cells in the multipoint HSDPA system, so that stale packets are not retained in internal buffers at the Node Bs following the RLC reset procedure. In some examples, the RLC reset procedure is only completed after confirmation that the flush of the internal buffers has been completed. Confirmation may be explicitly provided by each Node B utilizing a backhaul interface, or may be implicitly determined utilizing timers or signaling between the respective Node Bs.

  • Patent number: 8867511
    Abstract: A method, apparatus, and computer program product can provide for procedures at an access terminal for handling the delivery of packets from the MAC entity to the RLC entity, with an aim to reduce the occurrence of RLC resets that might otherwise be caused by out-of-order processing of control packets following a serving cell change. In one example, a MAC entity may insert an identifier into a packet delivered up to the RLC entity, to indicate whether the packet arrived from the current primary serving cell. In another example, a serving cell change procedure may include steps to flush a queue at the MAC entity and kill any running reordering release timers. In these ways potential problems caused by out-of-order control packets can be reduced or avoided.

  • Patent number: 8767625
    Abstract: A method for concurrent bandwidth aggregation (COBA) for a client via multiple wireless networks includes requesting a packet data session for a first path on a first wireless network using a first modem of the multi-modem UE via a packet core network of the first wireless network. The method further includes requesting a packet data session for a second path on a second wireless network via the packet core network of the first wireless network using a second modem of the multi-modem UE. The method also includes receiving packet data over at least the second path on the second wireless network via the packet core network of the first wireless network.

  • Patent number: 8644260
    Abstract: Methods and apparatus are described herein to manage a serving cell change. A HS-SCCH monitored set is maintained to store entries for all pending serving cell change requests. The HS-SCCH for each entry is monitored for a timer period. Once a change request has been confirmed for one entry, monitoring for the other entries continues until expiration of the associated timers.

  • Publication number: 20130250853
    Abstract: The present description provides methods and apparatuses for improved transfer control protocol (TCP) acknowledgement transmission during operation of a slow-start process in wireless environments. For example, in an aspect, the present disclosure presents a method of wireless communication, which may include receiving, at a radio network controller (RNC), a transmission control protocol (TCP) packet for a user equipment (UE) from a server. Furthermore, example methods may include reforming the TCP packet into a set of radio link control (RLC) packets. Additionally, in some examples, such methods may additionally include transmitting the set of RLC packets to a base station. Moreover, such methods may include sending an accelerated TCP acknowledgement message to the server based on the transmitting of the set of RLC packets to the base station.

  • Publication number: 20110317642
    Abstract: Various aspects of the disclosure provide an intra-Node B unsynchronized serving cell change enabling the typical loss of packets resulting from such a procedure to be reduced or eliminated. In one example, when a UE ceases listening to a downlink channel from a first cell provided by a Node B and starts to configure its receiver to listen to a downlink channel from a second cell provided by the Node B, a continued incrementing of a sequence number may be stalled in the transmission of packets to the UE. That is, the TSN space may be stalled, such that HARQ retransmissions recur beyond the preconfigured maximum number of retransmissions, until the UE indicates that the serving cell change is complete. In another example, the transmission of packets to the UE from the first cell may be halted until the UE indicates that the serving cell change is complete.
