Abstract: A method includes transmitting, at an LTE device configured to transmit data over an unlicensed band, first synchronization data over a first frequency channel of the unlicensed band during a timeframe. The method further includes transmitting, at one of the first LTE device or a second LTE device, second synchronization data over a second frequency channel of the unlicensed band during the same timeframe. The data transmissions of at least one of the first LTE device or the second LTE device are coordinated based on the synchronization data.

Abstract: TTI bundling is included for Msg3 transmissions in LTE communications. A reserved group of preambles or reserved set of random access preamble transmission opportunities are used to indicate user equipment (UE) need of uplink (UL) transmission of a TTI-bundled Msg3. The UE transmits the same redundancy version for transmissions within a TTI bundle as the eNB expects even if any of the transmissions are dropped due to collisions with an Msg3 transmission. In addition, co-existence of TTI bundling and UL semi-persistent scheduling (SPS) for TDD DL/UL configurations is provided using SPS intervals which are multiples of various fixed time periods.

Abstract translation: TTI捆绑包含在LTE通信中的Msg3传输。 使用保留的前导码组或预留的随机接入前导码传输机会组来指示用户设备（UE）对TTI绑定的Msg3的上行链路（UL）传输的需求。 即使由于与Msg3传输的冲突而导致任何传输丢失，UE也会传输针对TTI束内传输的相同冗余版本。 此外，使用作为各种固定时间段的倍数的SPS间隔来提供用于TDD DL / UL配置的TTI绑定和UL半永久调度（SPS）的共存。

Abstract: A method includes detecting, using a WiFi access point, channel use data indicating traffic on a plurality of channels of an unlicensed LTE band in a wireless network. The method further includes providing the channel use data to a Long Term Evolution (LTE) access point. The method further includes selecting, using the LTE access point, a channel for use in transmitting data by the LTE access point from among the plurality of channels based on the channel use data from the WiFi access point. The method further includes providing, from the LTE access point, an indication of an upcoming transmission configured to transmit data on the channel to the WiFi access point. The method further includes broadcasting one or more messages from the WiFi access point to one or more WiFi nodes, the one or more messages configured to prevent the WiFi nodes from transmitting on the channel.

Abstract: A method includes transmitting, at an access point configured to transmit data over an unlicensed band, a single message prior to transmitting data over a channel of the unlicensed band. The method further includes receiving, at the access point, a plurality of responses from a plurality of user equipment acknowledging the single message in response to the single message.
