摘要： Provided is a method and device for switching a primary/backup PW. When a primary PW is detected having changed into a Down status by a BFD session corresponding to the primary PW, PE searches for a matching switching information entry. When in the switching information entry indicates transmission switching is supported, and Failover value indicates that a packet is forwarded via a backup PW, the PE updates Failover value in a hardware protection switching entry to the Failover value in the switching information entry. When bRX in the switching information entry indicates reception switching is supported, the PE updates drop identifier in a hardware reception entry to a value indicating that a packet is received, and updates the bFS to a value indicating that transmission switching is not supported; and the PE reports a Down event of the primary PW.

摘要： A method and apparatus for uplink feedback for operating with a large number of carriers are disclosed herein. A method in a wireless transmit/receive unit (WTRU) includes receiving a plurality of transport blocks over a set of a plurality of configured carriers, generating hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for the transport blocks and determining a number of HARQ-ACK feedback bits to use for the HARQ-ACK feedback. Further, the WTRU may apply, to the HARQ-ACK feedback bits, Reed-Muller coding on a condition that the number of HARQ-ACK feedback bits is less than or equal to a threshold or convolutional coding on a condition that the number of HARQ-ACK feedback bits is greater than a threshold. The WTRU may then transmit the encoded HARQ-ACK feedback bits. In addition, the WTRU may conditionally append cyclic redundancy check (CRC) bits onto the HARQ-ACK feedback bits, and encode and transmit the CRC bits.

摘要： Disclosed are a method and a device for recovering an error without the retransmission of a data frame in a wireless LAN. The method for recovering an error in a wireless LAN may comprise the steps in which: a sender STA transmits a data frame to a receiver STA; if the sender STA does not receive a block ACK frame of the data frame from the receiver STA, the sender STA determines the reason for the non-reception of the data frame; if the sender STA determines that the reason for the non-reception of the data frame is the failure of transmission of the block ACK frame after the receiver STA receives the data frame, the sender STA transmits a PBAR data frame to the receiver STA; and the sender STA receives a PBAR block ACK frame from the receiver STA as a response to the PBAR data frame.

摘要： When a condition of handing over user equipment from a cell in which a first network device is located to a cell in which a second network device is located is met, the first network device sends first information to the second network device, where the first information includes at least one of a CWND, a slow start threshold, a window scale factor, a RWND, and a TCP segment length; the slow start threshold is a value of demarcation between a slow start state and a congestion state; the window scale factor is a window scale factor carried in a SYN packet when a TCP connection is set up; the RWND is a maximum data volume that can be received by the user equipment; and the TCP segment length is a length of a maximum TCP segment that can be sent by the first network device.

摘要： According to the present disclosure, CSI and/or a plurality of ACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. Once the trigger is received, the UE may transmit the CSI and/or GACK to the eNB. In this way HARQ feedback and/or CSI may be reliably communicated while reducing payload. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus send, to a UE, data transmissions associated with a first plurality of downlink subframes. In an aspect, the apparatus increments a counter for each data transmission sent to the UE. In a further aspect, the apparatus transmits, to the UE, a first trigger for a first GACK when a counter is greater than or equal to a threshold.

摘要： Some aspects of the disclosure provide for wireless communication systems in which scheduling information is transmitted to a scheduled entity to schedule transmission of uplink feedback control information by the scheduled entity. The feedback control information may be transmitted in short uplink control bursts or long uplink bursts. Selection between short uplink control bursts and long uplink bursts may be based on power headroom at the scheduled entity, interference in the short uplink control burst or the long uplink burst, loading of the short uplink control burst or the long uplink burst or processing capability of the scheduled entity.

摘要： Systems and methods are disclosed for providing efficient downlink Hybrid Automatic Request (HARQ) feedback. In some embodiments, a method of operation of a wireless device in a cellular communications system comprises receiving downlink control information from a radio access node in a first subframe T. The downlink control information comprises an indication of a HARQ timing offset K. The method further comprises transmitting downlink HARQ feedback to the radio access node in a subframe T+K. In this manner, HARQ feedback can be directly scheduled by the network, which in turn enables efficient HARQ feedback.

摘要： Aspects of the present disclosure provide techniques for enhanced transmission time interval (TTI) bundling design for machine type communications (MTC). A method for wireless communications by a wireless device is provided. The method generally includes determining a mapping of one or more uplink or downlink channels to one or more fixed bundling sizes, wherein each of the one or more fixed bundling sizes indicates a number of transmission time intervals (TTIs) over which a channel should be transmitted and processing transmission of the one or more uplink or downlink channels based on the mapping.
