Reporting in wireless communication networks
A method is performed by a wireless device for reporting to a base station, the wireless device being configured with one or more first criteria and one or more second criteria for triggering transmission of a report message, a first timer associated with the one or more first criteria, and a second timer associated with the one or more second criteria. The method comprises: transmitting a first report message to a base station, triggered by fulfilment of one of the first and second criteria; responsive to transmission of the first report message, initiating the first or second timer associated with the one of the first and second criteria; and refraining from transmitting a further report message triggered by fulfilment of the one of the first and second criteria while the initiated first or second timer is active.
1 . A method performed by a wireless device for reporting to a base station, the method comprising:
configuring one or more Maximum Permissible Exposure (MPE)-related criteria for triggering Power HeadRoom (PHR) reporting towards the base station;
configuring one or more non-MPE-related criteria for triggering PHR reporting towards the base station;
controlling a timing of PHR reporting triggered solely by the one or more MPE-related criteria according to a first prohibit timer; and
controlling a timing of PHR reporting triggered solely by the one or more non-MPE-related criteria according to a second prohibit timer that is separate from the first prohibit timer.
2 . The method of claim 1 , wherein controlling the timing of PHR reporting triggered solely by the one or more MPE-related criteria according to the first prohibit timer comprises transmitting a given PHR report that is triggered solely by the one or more MPE-related criteria and correspondingly starting the first prohibit timer, and not transmitting a next PHR report that is triggered solely by the one or more MPE-related criteria until expiration of the first prohibit timer.
3 . The method of claim 1 , wherein controlling the timing of PHR reporting triggered solely by the one or more non-MPE-related criteria according to the second prohibit timer comprises transmitting a given PHR report that is triggered solely by the one or more non-MPE-related criteria and correspondingly starting the second prohibit timer, and not transmitting a next PHR report that is triggered solely by the one or more non-MPE-related criteria until expiration of the second prohibit timer.
4 . The method of claim 1 , wherein the one or more MPE-related criteria comprise any one or more of the following: expiration of a periodic reporting timer, activation of a transmit power limitation at the wireless device for compliance with MPE requirements, a change in MPE-related transmit power limits at the wireless device, or more than a threshold change in MPE-related transmit power limits at the wireless device.
5 . The method of claim 1 , wherein the one or more non-MPE-related criteria comprise any one or more of: expiration of a periodic reporting timer, a change in path loss between the wireless device and the base station, or more than a threshold change in the pathloss.
6 . The method of claim 1 , wherein configuring the one or more MPE-related criteria and the one or more non-MPE-related criteria comprises receiving configuration signaling from the base station, indicating the one or more MPE-related criteria and the one or more non-MPE-related criteria.
7 . The method of claim 6 , wherein the configuration signaling further indicates the first and second prohibit timers.
8 . The method of claim 1 , wherein configuring the one or more MPE-related criteria and the one or more non-MPE-related criteria comprises using configuration information stored in the wireless device.
9 . A wireless device configured for reporting to a base station, the wireless device comprising:
transceiver circuitry for transmitting signals to the base station and receiving signals from the base station; and
processing circuitry configured to:
configure one or more Maximum Permissible Exposure (MPE)-related criteria for triggering Power HeadRoom (PHR) reporting towards the base station;
configure one or more non-MPE-related criteria for triggering PHR reporting towards the base station;
control a timing of PHR reporting triggered solely by the one or more MPE-related criteria according to a first prohibit timer; and
control a timing of PHR reporting triggered solely by the one or more non-MPE-related criteria according to a second prohibit timer that is separate from the first prohibit timer.
