Event triggered multi-link channel quality measurement and report for mission critical applications
摘要
說(shuō)明書
Systems, methods, and apparatuses for event triggered multi-link channel quality measurement and report for mission critical applications are described. A transmitter may allocate resource blocks for a transmission of a data packet and pilot signals on a set of component carriers (CCs). The transmitter may transmit the pilot signals on two or more CCs. A receiver may receive a resource grant that includes an allocation of resource blocks for a downlink transmission on the set of CCs. The receiver may receive a data packet across at least a portion of the set of CCs. The receiver may further receive a pilot signal on two or more CCs and may perform channel quality indicator (CQI) measurements in response to an indication received with the resource grant. The CQI measurements may be based on the pilot signals for the two or more CCs. The indication may be transmitted from the transmitter after determining that a number of the CCs do not have channel measurements which were performed within a time threshold. In some examples, transmitting CQI data includes transmitting CQI data for each of the two or more CCs on a single CC. The transmitter may receive CQI data on a single CC based on measurements of the pilot signals on two or more CCs, the measurements being triggered by the allocation of the resource blocks. The receiver may transmit a negative acknowledgement (NACK) in response to receiving the data packet. The transmitter may reallocate resource blocks for retransmission of the data packet across at least a portion of the set of CCs, the reallocating may be based on the received CQI data. The receiver may receive a second resource grant that includes a reallocation of resource blocks for retransmission of the data packet across at least a portion of the CCs, where the reallocation may be based on the CQI data.
