  • Patent Number: 11469,833
  • Publication Date: October 11, 2022
  • Appl. No: 15/097710
  • Application Filed: April 13, 2016
  • Assignees: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) (Stockholm, SE)
  • Claim: 1. A method for limiting Channel Quality Indicator (CQI) reporting from a User Equipment (UE) to a network node, the method comprising: transmitting, by the UE, at least one CQI report to the network node when the UE is operating in a discontinuous reception (DRX) mode, wherein the at least one CQI report is triggered according to one or more CQI reporting trigger rules, at least one of the one or more CQI reporting trigger rules is based on a scaled CQI feedback cycle Ψdefined as Ψ=T×μ, where T is a basic CQI feedback cycle and μ is a scaling factor, enabling dynamic scaling of the CQI feedback cycle, and the scaling factor is provided to the UE by the network node.
  • Claim: 2. The method according to claim 1 , wherein the scaling factor is provided to the UE in any of the following forms: as a cell specific value that is valid for all low activity states in a respective cell, or as at least one state specific value, each of which is valid for a specific state.
  • Claim: 3. The method according to claim 1 , wherein in addition to the scaled CQI feedback cycle, the at least one of the one or more CQI reporting trigger rules is based on a random transmission value to be used by the UE for randomly transmitting a first CQI report.
  • Claim: 4. The method according to claim 3 , wherein the random transmission value is a value between 0 and Ψ.
  • Claim: 5. A method, by a network node, for limiting Channel Quality Indicator (CQI) reporting from a User Equipment (UE) to the network node, the method comprising: configuring, by providing a scaling factor to the UE, a rule for triggering the UE to report CQIs when the UE is operating in a discontinuous reception (DRX) mode, wherein the rule for triggering the UE to report the CQIs is based on a scaled CQI feedback cycle Ψdefined as Ψ=T×μ, where T is a basic CQI feedback cycle and μ is the scaling factor, enabling dynamic scaling of the CQI feedback cycle.
  • Claim: 6. The method according to claim 5 , wherein the scaling factor is provided to the UE in any of the following forms: as a cell specific value that is valid for all low activity states in a respective cell, or as at least one state specific value, each of which is valid for a specific state.
  • Claim: 7. The method according to claim 5 , wherein in addition to the scaled CQI feedback cycle, the rule for triggering the UE to report the CQIs is based on a random transmission value to be used by the UE for randomly transmitting a first CQI report.
  • Claim: 8. The method according to claim 7 , wherein the random transmission value is a value between 0 and Ψ.
  • Claim: 9. A User Equipment (UE) for limiting Channel Quality Indicator (CQI) reporting from the UE to a network node, the UE comprising: a communication unit configured to transmit at least one CQI report to the network node when the UE is operating in a discontinuous reception (DRX) mode, wherein: the at least one CQI report is triggered according to one or more CQI reporting trigger rules, at least one of the one or more CQI reporting trigger rules is based on a scaled CQI feedback cycle Ψdefined as Ψ=T×μ, where T is a basic CQI feedback cycle and μ is a scaling factor, enabling dynamic scaling of the CQI feedback cycle, and the communication unit is configured to be provided with the scaling factor from the network node.
  • Claim: 10. The UE according to claim 9 , wherein the scaling factor is provided in any of the following forms: as a cell specific value that is valid for all low activity states in a respective cell, or as at least one state specific value, each of which is valid for a specific state.
  • Claim: 11. The UE according to claim 9 , wherein in addition to the scaled CQI feedback cycle, the at least one of the one or more CQI reporting trigger rules is based on a random transmission value to be used by the UE for randomly transmitting a first CQI report.
  • Claim: 12. The UE according to claim 11 , wherein the random transmission value is a value between 0 and Ψ.
  • Claim: 13. A network node for limiting Channel Quality Indicator (CQI) reporting from a User Equipment (UE) to the network node, the network node comprising: a communication unit configured to configure, by providing a scaling factor to the UE, a rule for triggering the UE to report CQIs when the UE is operating in a discontinuous reception (DRX) mode, wherein the rule for triggering the UE to report the CQIs is based on a scaled CQI feedback cycle Ψdefined as Ψ=T×μ, where T is a basic CQI feedback cycle and μ is the scaling factor, enabling dynamic scaling of the CQI feedback cycle.
  • Claim: 14. The network node according to claim 13 , wherein the scaling factor is provided to the UE in any of the following forms: as a cell specific value that is valid for all low activity states in a respective cell, or as at least one state specific value, each of which is valid for a specific state.
  • Claim: 15. The network node according to claim 13 , wherein, in addition to the scaled CQI feedback cycle, the rule for triggering the UE to report the CQIs is based on a random transmission value to be used by the UE for randomly transmitting a first CQI report.
  • Claim: 16. The network node according to claim 15 , wherein the random transmission value is a value between 0 and Ψ.
