Abstract
A method, computer program and apparatus operate when resuming data transmission/reception upon activation of a serving cell, or after a long in-device coexistence interference avoidance gap, to determine whether to report to a network access node an in-device coexistence interference indicator value and send the in-device coexistence interference indicator value to the network access node, The in-device coexistence interference indicator value is reported to the network access node for a certain period if any periodic channel quality indication resource is configured for the cell, or if an aperiodic channel quality indication for the cell is requested from the network access node.
Claims28
An apparatus, comprising:
- at least one processor;
- and
- at least one memory storing a computer program;
- in which the at least one memory with the computer program is configured with the at least one processor to cause the apparatus to at least:
- receiving, by Medium Access Control (MAC) signaling from a network access node for a primary serving cell, an activation message specifying that a secondary serving cell is to be activated for the apparatus, wherein the activation message indicates a timing of when a channel quality indication result for the secondary serving cell should be reported, and
- reporting to the network access node for the primary serving cell a valid channel quality indication result for the secondary serving cell following the timing, wherein the valid channel quality indication result for the secondary serving cell is not available until a first subframe that has a reference signal is available after the activation of the secondary serving cell.
A method, comprising:
- receiving, by Medium Access Control (MAC) signaling from a network access node for a primary serving cell, an activation message specifying that a secondary serving cell is to be activated for the apparatus, wherein the activation message indicates a timing of when a channel quality indication result for the secondary serving cell should be reported, and reporting to the network access node for the primary serving cell a valid channel quality indication result for the secondary serving cell following the timing, wherein the valid channel quality indication result for the secondary serving cell is not available until a first subframe that has a reference signal is available after the activation of the secondary serving cell.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory storing a computer program;
- in which the at least one memory with the computer program is configured with the at least one processor to cause the apparatus to at least:
- transmit to a user equipment, by Medium Access Control (MAC) signaling from the apparatus for a primary serving cell, an activation message specifying that a secondary serving cell is to be activated for the user equipment, wherein the activation message indicates a timing of when a channel quality indication result for the secondary serving cell should be reported;
- and
- receive from the user equipment, a valid channel quality indication result for the secondary serving cell following the timing, wherein the valid channel quality indication result for the secondary serving cell is not available until a first subframe that has a reference signal is available after the activation of the secondary serving cell.
