Method, apparatus and system for network energy saving
A wireless device may transmit a wake up request indicating a request to exit an energy saving state for one or more cells. At least one uplink transmission or at least one downlink transmission is not performed during an energy saving state.
1 . A method comprising:
receiving, by a wireless device:
cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration parameters for one or more cells; and
a first radio resource control configuration parameter of a first uplink logical channel indicating that arrival of data of the first uplink logical channel triggers a wake up request;
determining, based on the cell DTX DRX configuration parameters, a network energy saving state for the one or more cells;
transmitting, in response to arrival of data of the first uplink logical channel, a wake up request indicating a request to exit the energy saving state for the one or more cells; and
wherein:
the wake up request is based on one or more of an uplink control information and an uplink reference signal and a medium access control (MAC) control element (CE) and a random access preamble; and
at least one uplink transmission or at least one downlink transmission is not performed during the energy saving state.
2 . The method of claim 1 , wherein a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB) is not transmitted via the one or more cells during the network energy saving state.
3 . The method of claim 1 , wherein the transmitting the wake up request is via a physical uplink control channel or a physical uplink shared channel.
4 . The method of claim 1 , further comprising entering a non-network energy saving state in response to transmitting the wake up request.
5 . The method of claim 4 , wherein, the at least one uplink transmission or the at least one downlink transmission is performed in response to entering the non-network energy saving state.
6 . The method of claim 1 , wherein the at least one uplink transmission or the at least one downlink transmission is performed after exiting the energy saving state.
7 . The method of claim 1 , wherein:
the DTX DRX configuration parameters indicate a pattern; and
the determining is based on the pattern.
8 . A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive:
cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration parameters for one or more cells; and
a first radio resource control configuration parameter of a first uplink logical channel indicating that arrival of data of the first uplink logical channel triggers a wake up request;
determine, based on the cell DTX DRX configuration parameters, a network energy saving state for the one or more cells;
transmit, in response to arrival of data of the first uplink logical channel, a wake up request indicating a request to exit the energy saving state for the one or more cells; and
wherein:
the wake up request is based on one or more of an uplink control information and an uplink reference signal and a medium access control (MAC) control element (CE) and a random access preamble; and
at least one uplink transmission or at least one downlink transmission is not performed during the energy saving state.
9 . The wireless device of claim 8 , wherein a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB) is not transmitted via the one or more cells during the network energy saving state.
10 . The wireless device of claim 8 , wherein the transmitting the wake up request is via a physical uplink control channel or a physical uplink shared channel.
11 . The wireless device of claim 8 , further comprising entering a non-network energy saving state in response to transmitting the wake up request.
12 . The wireless device of claim 11 , wherein, the at least one uplink transmission or the at least one downlink transmission is performed in response to entering the non-network energy saving state.
13 . The wireless device of claim 8 , wherein the at least one uplink transmission or the at least one downlink transmission is performed after exiting the energy saving state.
14 . The wireless device of claim 8 , wherein:
the DTX DRX configuration parameters indicate a pattern; and
the determining is based on the pattern.
15 . A system comprising:
a base station; and
a wireless device comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the wireless device to: receive, from the base station: cell discontinuous transmission (DTX) discontinuous reception (DRX) configuration parameters for one or more cells; and a first radio resource control configuration parameter of a first uplink logical channel indicating that arrival of data of the first uplink logical channel triggers a wake up request; determine, based on the cell DTX DRX configuration parameters, a network energy saving state for the one or more cells; transmit, in response to arrival of data of the first uplink logical channel, a wake up request indicating a request to exit the energy saving state for the one or more cells; and wherein: the wake up request is based on one or more of an uplink control information and an uplink reference signal and a medium access control (MAC) control element (CE) and a random access preamble; and at least one uplink transmission or at least one downlink transmission is not performed during the energy saving state.
