Abstract: There are provided mechanisms for monitoring search spaces. A first method performed by a wireless device comprises receiving an Orthogonal Frequency-Division Multiplexing (OFDM) symbol in a downlink slot. At least part of the OFDM symbol is included in a device-specific search space and in a common search space. The first method comprises monitoring the device-specific search space for at least one device-specific reference signal (RS) and monitoring the common search space for at least one non-device-specific RS. In a second method, a radio access network node transmits an OFDM symbol included in a device-specific search space and in a common search space. The device-specific search space contains a device-specific RS, or the non-device specific search space contains a non-device-specific RS, or both of these apply.

Abstract: A wireless device monitors search spaces by receiving an orthogonal frequency-division multiplexing, OFDM, symbol in a downlink slot. The OFDM symbol is included in a control-resource set, CORESET, of resource elements configured to carry control information. The CORESET is associated with at least one property. The wireless device identifies at least one first property of the at least one property of the CORESET. Then, the wireless device monitors at least one particular search space for a control message related to the wireless device based on the identified at least one first property of the CORESET.

Abstract: According to some embodiments, a wireless device receives (1020) a discovery burst from a network node (115). The same discovery burst includes multiple signals within at least one subframe, each of the multiple signals having one or more associated measurement functions. At least one of the multiple signals is received with multiple repetitions within the same discovery burst and two or more repetitions of the same type of signal can be combined by the wireless device. The wireless device performs (1024) at least one radio measurement based at least in part on a particular one of the signals of the discovery burst. The performed at least one radio measurement corresponds to a measurement function associated with the particular signal of the discovery burst.

Abstract: Systems and methods for performing power control of a physical channel in a communication system are provided. In one exemplary embodiment, a method in a wireless device of performing power control of a physical channel in a wireless communication system may include determining a transmission power for a transmission on the physical channel according to a power control loop. Further, the loop may specify the transmission power based on at least one parameter. Also, a value of the at least one parameter may be dependent on which of different transmission time interval (TTI) lengths defined as usable on the physical channel is selected for the transmission on the physical channel.

Abstract: A user equipment, UE, is configured to receive downlink control information, DCI, transmitted to the UE by a primary cell in a wireless communication system. The UE comprises one or more processing circuits that shall assume that a DCI message which has a common payload size and the same first control channel element index, but different bit fields, in a common search space and a UE-specific search space is transmitted by the primary cell in the common search space or the UE-specific search space, based on radio resource control, RRC, configuration of the UE.
