    Abstract: A hybrid automatic repeat request (HARQ) process enables a retransmission to be sent on a carrier (or medium, set of frequencies, band, etc.) different from the carrier on which the previous transmissions (initial transmission and/or retransmissions) were sent. An enhanced HARQ process can improve system performance by aiding user throughput, system throughput, and delay performance by making retransmissions possible even when the unlicensed band is not available (e.g., when occupied by other RATs or the same RAT deployed by another operator). For example, a transmitter sends a subpacket in an unlicensed band. The receiver feeds back a NACK to the transmitter due to the packet decoding failure. If the medium is not idle, the transmitter sends the retransmission in another band or another channel that can be either a licensed band/channel or another unlicensed band/channel. The retransmission can be sent in multiple licensed and/or unlicensed bands/channels at the same time.

    Abstract translation: 混合自动重传请求（HARQ）过程使得能够在与先前发送（初始发送和/或重发）被发送的载波不同的载波（或媒体，频率组，频带等）上发送重传 。 增强的HARQ进程可以通过即使当非许可频带不可用时（例如，当由其他RAT或由另一个运营商部署的相同的RAT占用）时通过使重传成为可能来辅助用户吞吐量，系统吞吐量和延迟性能来提高系统性能。 例如，发射机在非授权频带中发送子分组。 由于分组解码失败，接收机将NACK反馈给发射机。 如果介质不是空闲的，则发射机在另一个频带或可以是许可频带/频道或另一个未许可频带/频道的另一个频道上发送重传。 可以同时在多个许可的和/或未许可的频带/频道中发送重传。

    Abstract: Technology for a user equipment (UE) operable to perform mission critical communications with an eNodeB is disclosed. The UE can transmit a physical random access channel (PRACH) signal to the eNodeB that indicates a mission critical communication to be performed between the UE and the eNodeB. The PRACH signal can be transmitted in accordance with a first transmission time interval (TTI). The UE can receive a random access response (RAR) message from the eNodeB that includes a timing advance (TA) and a resource allocation for the mission critical communication. The RAR message can be transmitted from the eNodeB using a second TTI. The UE can perform the mission critical communication with the eNodeB in an uplink using the TA and the resource allocation indicated in the RAR message. The mission critical communication can be performed using a physical uplink shared channel (PUSCH) and in accordance with the second TTI.
