Abstract:
Embodiments of UE and methods for measurement of Reference Signal Received Quality (RSRQ) are generally described herein. The UE may be configured to determine an RSRQ of a serving cell and an RSRQ of a target cell based on an indicated RSRQ measurement type. The measurement type may be received as part of a measurement configuration Information Element (IE) that indicates a first or second RSRQ measurement type. For the first RSRQ measurement type, the RSRQ may be determined based on a Received Signal Strength Indicator (RSSI) over common reference signals (CRS). For the second RSRQ measurement type, the RSRQ may be determined based on an RSSI that is based on a received power of one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols received at the UE.
Abstract:
Systems and methods for signaling in an increased carrier monitoring wireless communication environment are disclosed herein. In some embodiments, a user equipment (UE) may include control circuitry to configure the UE for increased carrier monitoring; determine, based on a first signal received from a network apparatus, whether a reduced performance group carrier is configured; determine, based on a second signal received from the network apparatus, whether a scaling factor is configured; and in response to a determination that no reduced performance group carrier is configured and a determination that no scaling factor is configured, allow the UE to monitor fewer carriers than required by increased carrier monitoring. Other embodiments may be disclosed and/or claimed.

The UE may include circuitry configured to determine a plurality of signals from one or more cells, determine a first value for a first performance metric associated with a first cell of the one or more cells, wherein the first value is determined from a first measurement, select the first cell for a first communication based on the first value, determine first location information associated with the UE, determine, following the first measurement and using the first location information, that the UE is stationary, and delay, in response to the determination that the UE is stationary, a second measurement of the first performance metric. In various alternate embodiments, different measurement types may be used for mobility and channel quality determinations. In further embodiments, only measurements for unused channels may be delayed.
