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.

LAA-LTE communication in an unlicensed spectrum

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.

WIFI-coordinated LAA-LTE

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.

Synchronization channel structure for a shared channel

TTI bundling is included for Msgtransmissions 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 Msg. 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 Msgtransmission. 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.

Transmission time interval (TTI) bundling operation within communication systems

A method, system, and base station for deterministically selecting a downlink transmission mode and rank in a Long Term Evolution (LTE) configured wireless communication system. The Transmission Mode Selection (TMS) utility receives from a wireless device a request for downlink physical downlink shared channel (PDSCH) service using a particular transmission mode and specific rank. The TMS utility determines an estimate of the throughput corresponding to the request. In addition, the TMS utility obtains throughput estimates of other distinct pairings of transmission mode and rank to compare with the throughput estimate corresponding to the request. The TMS utility utilizes device feedback information and HARQ error information that are already existing/available in order to determine the best transmission mode and rank pair, according to the best Error-Adjusted-Throughput.
