LOAD BASED LTE/LTE-A WITH UNLICENSED SPECTRUM

摘要

In one aspect of the disclosure, a method of wireless communication includes receiving, at a transmitter, data for transmission over an unlicensed carrier, calculating, at the transmitter, a first available extended clear channel assessment (ECCA) opportunity of the unlicensed carrier after the receiving, wherein the calculating uses at least network information and a pseudo-random number, performing a clear channel assessment (CCA) check, by the transmitter, on the unlicensed carrier at the first available ECCA opportunity, in response to detecting a clear CCA check, transmitting channel reserving signals, by the transmitter, onto the unlicensed carrier, and in response to failing to detect the clear CCA check, calculating, by the transmitter, a next available ECCA opportunity of the unlicensed carrier using at least the network information and another pseudo-random number.

主权项

1. A method of wireless communication, comprising:
receiving, at a transmitter, data for transmission over an unlicensed carrier; calculating, at the transmitter, a first available extended clear channel assessment (ECCA) opportunity of the unlicensed carrier after the receiving, wherein the calculating uses at least network information and a pseudo-random number; performing a clear channel assessment (CCA) check, by the transmitter, on the unlicensed carrier at the first available ECCA opportunity; in response to detecting a clear CCA check, transmitting channel reserving signals, by the transmitter, onto the unlicensed carrier; and in response to failing to detect the clear CCA check, calculating, by the transmitter, a next available ECCA opportunity of the unlicensed carrier using at least the network information and another pseudo-random number.
