Abstract
Embodiments described herein relate to methods and apparatus for performing link adaptation processes in a network. A method in a transmitting node in a wireless local area network comprises obtaining a first traffic flow for transmitting to a receiving node, wherein the first traffic flow is associated with a first category based on a reliability requirement associated with the first traffic flow; selecting a first link adaptation process from a plurality of link adaptation processes based on the first category; and transmitting the first traffic flow to the receiving node based on the first link adaptation process.
Claims18
A method in a transmitting node in a wireless local area network, the method comprising:
- obtaining first and second traffic flows for transmitting to a receiving node, wherein the first traffic flow is categorized into a first category based on a reliability requirement associated with the first traffic flow, wherein the second traffic flow is categorized into a second category based on a reliability requirement associated with the second traffic flow;
- wherein the first and second categories are different;
- selecting a first link adaptation process from a plurality of link adaptation processes for the first category, and a second link adaptation process from the plurality of link adaptation processes for the second category, wherein the first and second link adaptation processes are different and the second category is associated with lower reliability requirement than the first category;
- transmitting the first traffic flow to the receiving node based on the first link adaptation process;
- and
- transmitting the second traffic flow to the receiving node based on the second link adaptation process;
- wherein the second link adaptation process comprises updating information relating to a probability of successful transmission and/or an expected throughput associated with at least one sample data rate tested for the second traffic flow;
- and
- wherein the first link adaptation process comprises selecting a first data rate for the first traffic flow from the at least one sample data rate tested for the second traffic flow based on the updated information from the second link adaptation process.
A transmitting node in a wireless local area network, the transmitting node comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the transmitting node is operative to:
- obtain first and second traffic flows for transmitting to a receiving node, wherein the first traffic flow is associated with a first category based on a reliability requirement associated with the first traffic flow, wherein the second traffic flow is categorized into a second category based on a reliability requirement associated with the second traffic flow;
- wherein the first and second categories are different;
- select a first link adaptation process from a plurality of link adaptation processes for the first category, and a second link adaptation process from the plurality of link adaptation processes for the second category, wherein the first and second link adaptation processes are different and the second category is associated with lower reliability requirement than the first category;
- transmit the first traffic flow to the receiving node based on the first link adaptation process;
- transmit the second traffic flow to the receiving node based on the second link adaptation process;
- and
- wherein the second link adaptation process comprises updating information relating to a probability of successful transmission and/or an expected throughput associated with at least one sample data rate tested for the second traffic flow;
- and
- wherein the first link adaptation process comprises selecting a first data rate for the first traffic flow from the at least one sample data rate tested for the second traffic flow based on the updated information from the second link adaptation process.
