摘要： Providing for improved acknowledgment and retransmission protocols for wireless communication is described herein. By way of example, the acknowledgment and retransmission protocols can comprise including a poll element, or reply command, within a data unit that is part of a wireless transmission. A timer is set following sending the wireless transmission, and if a reply is not received within expiration of the timer, retransmission is triggered. According to specific aspects, retransmission comprises resending the data unit that includes the poll element or reply command. In this manner, redundant retransmission can be mitigated, whether because a receiver fails to successfully receive one or more subsets of the wireless transmission, or because the transmitter fails to obtain a reply to the wireless transmission.

摘要： A method, apparatus, and computer program product for wireless communication are provided in which a determination is made of a first power available for transmitting a first signal using a first radio access technology while simultaneously transmitting a second signal using a second radio access technology different from the first radio access technology. An uplink grant is received and a determination is made regarding a second power for transmitting the first signal on uplink using the first radio access technology based on the uplink grant. A determination is made regarding a difference between the first power and the second power. Information related to the difference is reported via the first radio access technology based on a trigger. The reporting information is triggered when the change of a power backoff from a last report exceeds a selected threshold.

摘要： Systems and methodologies are described that facilitate formation and/or dispatch of radio link control (RLC) protocol status reports to a base station. The system can include components that quantify an absence of protocol data units, ascertain whether a number of absent protocol data units exceeds the size of a transmission side grant, insert a sequence number associated with a first absent protocol data unit into an acknowledgement sequence number field associated with a partial status report, incorporates the sequence number associated with the first absent protocol data unit in the partial status report, includes sequence numbers of subsequent absent protocol data units into the partial status report without exceeding the transmission side grant, and sends the partial status report to the base station.

摘要： Explicit signaling of End of Handover (EoH) advantageously indicates when user equipment (UE) has stopped using Packet Data Convergence Protocol (PDCP) handover mode. Radio Link Control (RLC) Acknowledge Mode (AM) delivers in order ensuring that all reordered packets have been received with no risk of delivering a gap packet when no longer in handover mode that would otherwise cause Hyper Frame Number (HFN) to be out of synchronization. Substantially at a time evolved Base Node (eNB) determines a gap will not be filled, eNB can convey an EoH indication to a served UE and can then deliver the PDCP Service Data Units (SDUs) with gaps to upper layers without delay.

摘要： This innovation relates to systems and methods for transmission of protocol data units, and more particularly to processing polling requests from a radio link control peer. A radio link control transmitter can poll a receiver to obtain a report regarding the status of a set of data packets, and the polls can be sent in-band with a data packet. The receiver can determine to wait before sending the status report based on one or more characteristics of the received data packets.

摘要： A transmission entity (e.g., user equipment (UE)) is expected to reduce the segmentation of Radio Link Control (RLC) Service Data Units (SDUs) while also minimizing padding. Signaling or provisioning of a constraint value such as a maximum padding amount or minimum segmentation size is employed in a determinative way in the UE to balance these objectives. A receiving entity (e.g., evolved base node (eNB)) benefits from being able to signal these parameters, whose application to RLC instances can discriminate between data and signaling radio bearers. Compliance can also be voluntary, such as the network entity employing at least a portion of the same approach on the downlink.
