The present application relates to devices and components including apparatus, systems, and methods for reference signal indication for idle or inactive user equipments.

Technologies for reference signal indication

The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals or synchronization signal. In an example, timing requirements for performing such measurements can be dynamically changed depending on, at least, a measurement on one of the reference signal or the synchronization signal.

Dynamic measurement period for wireless communications in a high-speed mode

A wake up signal scheme between a network and a user equipment (UE) operating in a Discontinuous Reception (DRX) state. The UE monitors a wake up signal (WUS) occasion to determine whether a WUS is received during the WUS occasion, when the WUS is received, determines whether the WUS identifies the UE, when the WUS is received and identifies the UE, monitors an OnDuration of a Discontinuous Reception (DRX) cycle corresponding to the WUS and when the WUS is not received or the WUS does not identify the UE, remains in a sleep state during the OnDuration corresponding to the WUS.

Wake-up signal for discontinuous reception operations

A user equipment (UE) receives reference signals during a discontinuous reception (DRX) cycle to perform frequency and timing tracking or automatic gain control (AGC). The UE receives configuration information corresponding to a reference signal that is to be transmitted to a user equipment (UE) when the UE is in a first operating state, receives the reference signal from a cell of a network when the UE is in the first operating state, performs one of frequency and timing tracking or automatic gain control (AGC) using the reference signal and receives a signal from the cell during a time window that the UE is scheduled to utilize an active mode of data exchange processing.

Tracking reference signal enhancements for new radio

Systems and methods are provided for a user equipment (UE) to perform frequency offset (FO) delta tracking. For an anchor component carrier (CC), the UE wakes up to perform tracking updates on a plurality of successive DRX cycles. For the non-anchor CC, the UE determines a minimum update interval &#x394;t, and schedules wake-ups on a first subset of the plurality of successive DRX cycles based on the minimum update interval &#x394;t. For the first subset of the plurality of successive DRX cycles with scheduled wake-ups, the UE performs the tracking updates on the non-anchor CC and updates an FO delta between the anchor CC and the non-anchor CC. For a second subset of the plurality of successive DRX cycles without the scheduled wake-ups on the non-anchor CC, the UE applies the FO delta to correct for a frequency error.

Frequency offset delta tracking for NR connected mode discontinuous reception carrier aggregation

Apparatuses (including user equipment (UE) and modem chips for UE), systems, and methods for calculating more accurate Reference Signal Received Power (RSRP) measurements and/or detecting/eliminating ghost cells from a list of (supposed) neighboring cells are described. In one method, the cross-correlations between adjacent Cell-specific Reference Signals (CRSs) are used to calculate the RSRP and to detect any ghost cells in a list of (supposed) neighboring cells. Any detected ghost cell may be deleted from any searches and measurements by the UE, and may also be reported to the network.

System and method for RSRP measurement in an LTE UE receiver

Apparatuses (including user equipment (UE) and modem chips for UE), systems, and methods for reducing false alarms (FAs) and miss-detections (MDs) in cell search results are described. In one method, the minimum of a value for the accumulated metric for a first short code and a value for the accumulated metric for a second short code is used as a pruning metric for each candidate cell. One or more thresholds are applied to the pruning metric to determine whether the candidate cell will be pruned from the final candidate cell list.

System and method for cell search enhancement in an LTE system

Certain aspects of the present disclosure relate to methods and apparatus for Channel Quality Indicator (CQI) reporting after resumption of Long Term Evolution (LTE) after a temporary suspension. In certain aspects, in order to minimize performance penalty to LTE on resumption after an LTE tune away for example to service a different Radio Access Technology, information available from before the LTE tune away may be used in addition to one or more additional parameters for determining how to perform LTE CQI calculation/update after tuning back to LTE. In certain aspects, a decision regarding whether a User Equipment (UE) reports a CQI based on channel conditions before the LTE tune away or reports a CQI based on channel conditions after tuning back to LTE may be based on a value of the Doppler estimate, a time duration of the LTE tune away, or a combination thereof.

Methods and apparatus for determining how to perform operations after communication suspend based on information before the suspend

Implementations and techniques for assigning source nodes to a select group in a wireless communication network are generally disclosed.

Assigning source nodes to a select group in a wireless communication network

A method and apparatus for enhancing uplink operations in a CDMA system is provided. The method may include receiving a rate control value and a transmit power value from a node B, wherein the rate control value is determined through uplink scheduling by the node B, and wherein the transmit power value is selected by the node B to maintain a signal to interference plus noise (SINR) metric within a threshold for a pilot channel, transmitting control channel information at a first power level determined from the transmit power value, and using a first average power tracking unit to generate the first selected transmit power and transmitting data channel information at a second power level determined from both the rate control value and the transmit power value.
