Signaling indication to reduce power consumption for MTC devices
A method for a user equipment, a method for a network equipment, a user equipment and a network equipment is disclosed. The network equipment transmits a signal pertaining to if control information is present in a first time period while the user equipment determines if a signal pertaining to control information is present in a first time period. The network equipment transmits control information to a UE in accordance with the transmitted signal while the user equipment decides whether to attempt to decode the control information depending on the determination.
1. A method for a user equipment, UE, comprising
determining if a signal pertaining to control information is received in a first time period, wherein the signal indicates whether control information is present; and
deciding whether to attempt to decode the control information depending on the determination,
wherein the signal comprises a sequence of symbols, where a length of the sequence depends on the maximum length of a control channel search space of a control channel carrying the control information.
2. The method according to claim 1 , wherein the method comprises receiving an indication whether the signal will be used or not for indicating a presences of control information intended for the UE in a System Information message.
3. A user equipment, UE, comprising processing circuitry and radio circuitry, wherein the UE is configured to:
determine if a signal pertaining to control information is received in a first time period, wherein the signal indicates whether control information is present; and
decide whether to attempt to decode the control information depending on the determination,
wherein the signal comprises a sequence of symbols, where a length of the sequence depends on the maximum length of a control channel search space of a control channel carrying the control information.
4. The UE according to claim 3 , wherein the UE is further configured to receive an indication whether the signal will be used or not for indicating a presences of control information intended for the UE in a System Information message.
