摘要： Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc . can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

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： Systems, methods, and apparatuses are disclosed to facilitate wireless communications. User equipment (UE), such as a mobile device, identifies data congestion and transmits a recommended data rate modification wireless signal (e.g., a recommended reduced data rate) to the base station that is transmitting data to the UE. The base station may reduce the data rate of the down link (DL) to the reduced data rate. The UE may then receive data from the base station at the reduced data rate. Therefore, flow control may be implemented at the base station side (e.g., sometimes referred to as the Network (NW) side) based upon the reduced data rate modification determined and transmitted by the UE to the base station. In this way, the data rate transmission to the UE can be reduced to allow the UE to successfully process received data and successfully perform its functions.
摘要翻译：公开了系统，方法和装置以便于无线通信。诸如移动设备的用户设备（UE）识别数据拥塞，并向正在向UE发送数据的基站发送建议的数据速率修改无线信号（例如推荐的减少数据速率）。基站可以将下行链路（DL）的数据速率降低到降低的数据速率。然后，UE可以以减小的数据速率从基站接收数据。因此，基于由UE向基站确定和发送的减少的数据速率修改，可以在基站侧（例如，有时称为网络（NW）侧）实现流量控制。以这种方式，可以减少到UE的数据速率传输，以允许UE成功地处理接收的数据并成功地执行其功能。

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： 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.

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： An efficient use of downlink (DL) air-interface bandwidth during handoff of user equipment from a source cell to a target is provided. In conjunction with a handoff message to ensure receipt, expedited status exchanges are provided so that initial communications do not require a subsequent retransmission of duplicate data. A method for transmitting a dedicated Random Access Channel (RACH) preamble and cell information, receiving a RACH from the user equipment to start communication, and transmitting a handover message and a radio link control (RLC) status message or an UL grant in response to receiving the RACH is provided. Also, a method for receiving a handover message and target cell information from a source cell to start handover negotiations, initiating communication with target cell using the target cell information, receiving a handover message and (RLC) status message, and using the received information to approximate status reporting is provided.

摘要： Methods, systems, and devices for wireless communications are described. A wireless node may receive one or more data messages which may include a set of packets that may each be associated with a sequence number. The set of packets may be received with a gap in the set of sequence numbers, indicating missing packets. The wireless node may forward the set of packets to a processing layer of the wireless node. The wireless node may then accept, from the processing layer of the wireless node, a set of duplicate (DUP) acknowledgment (ACK) messages based on the set of packets being forwarded to the processing layer while having the gap in the set of sequence numbers. The wireless node may transmit, a subset of the set of DUP ACKs rather than all of the set of DUP ACKs to another wireless node, such as a base station.
