    Abstract: Aspects of the present disclosure generally relate to wireless communication. For example, aspects of the present disclosure provide techniques for determining one or more modulation orders to be used for the communication of control channels and/or data channels. An exemplary method, performed by a UE, may include receiving downlink control information (DCI) that allocates resources for a communication, the DCI may include a first field that indicates a transport block size (TBS) of the communication and a second field, different from the first field, that indicates a modulation order of the communication, wherein the communication includes a transmission or a reception, and processing the communication according to the indicated modulation order. Numerous other aspects are provided.

    Abstract: In order to balance the power requirements of a MIMO receiver with the gains that may be achieved through its use, an apparatus determines whether a current configuration of the UE supports iterative MIMO reception. When it is determined that the current configuration of the UE supports iterative MIMO reception, the apparatus determines whether at least one parameter of the received signal is within a corresponding target condition, respectively, for each of the at least one parameters, e.g., including determining whether a scheduling percentage meets a scheduling threshold and whether an error rate is within an error rate range. When both the configuration supports iterative MIMO reception and the signal parameter(s) meet the corresponding target condition(s), the apparatus uses the iterative MIMO receiver. If not, the apparatus uses a serial receiver.

    Abstract: Methods and apparatus for computing measurement metrics in a wireless communications network are provided. One example method generally includes obtaining a channel impulse response (CIR) from one or more reference signals (RSs) transmitted from one or more antennas of a base station (BS); calculating an absolute square per element of the CIR to generate channel energy response (CER) elements; calculating a threshold value based on a noise variance estimated from a portion of the CER elements; selecting CER elements that exceed the threshold value; and computing a reference signal received power (RSRP) value based on the selected CER elements.

    Abstract: In a wireless network, a base station (BS) may send a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The synchronization signals may be used by user equipments (UEs) for cell detection and acquisition. A typical searching operation may involve first locating the PSS sequences transmitted by neighboring BSs, followed by SSS detection. Described further herein are algorithms that result in the detection of the PSS and the SSS from a BS. A method for detecting a BS generally includes sampling a received signal from receiver antennas to obtain a sampled sequence, analyzing the sampled sequence to detect a PSS in a current half-frame (HF), calculating signal-to-noise ratio (SNR) metrics based on the detected PSS, combining the calculated SNR metrics with SNR metrics from previous HFs, analyzing the combined SNR metrics to obtain timing information, and analyzing the sampled sequence using the timing information to detect a SSS.
