A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Tracking reference signal (TRS) for idle mode user equipment (UE)

Techniques are described herein that allow a user equipment (UE) to configure a subcarrier spacing value while monitoring synchronization signals of neighboring cells. In some wireless communication systems, synchronization signals in given radio frequency spectrum band may be transmitted using one of a plurality of different subcarrier spacings. In some cases, a network entity, such as a base station, may transmit an indication to the UE that indicates the subcarrier spacing used by a cell to transmit a specific set of synchronization signals. In some cases, the UE may select a subcarrier spacing based on a database of subcarrier spacings stored locally by the UE. In some cases, the UE may select the subcarrier spacing based on a predetermined configuration.

Techniques for selecting subcarrier spacing for signal detection

One or more aspects of the disclosure provide an efficient equalization scheme capable of mitigating multi-path interference on channels with large delay spread using short-length equalizers. That is, by dividing stored samples of a signal received on the multi-path channel by time into a plurality of clusters, a short-length equalizer can be utilized in an iterative fashion on each of the clusters, thus eliminating the need for a large length equalizer while still providing improved performance over that of a Rake receiver at large delay spreads. Other aspects, embodiments, and features are also claimed and described.

Apparatus and method for iterative interference cancellation in a wireless communication network

A mobile station that is configured to perform common channel cancellation may include a parameter estimation unit that is configured to estimate parameters for generating a common channel error. The mobile station may also include a common channel generation unit that is configured to generate the common channel error based on the parameters. The mobile station may also include an adder that is configured to subtract the common channel error from received data samples.
