Abstract: Certain aspects of the present disclosure generally relate to techniques for combining a plurality of decision metrics of a scrambled payload in a 5G wireless communications system. For example, in some cases, combining decision metrics of a scrambled payload may generally involve receiving a first payload at a receiver that was scrambled both before and after encoding, generating a second payload at the receiver with selectively set payload mask bits, and using the selectively-set payload mask bits in the second payload to descramble the first payload.

Abstract: According to certain aspects of the present disclosure, indicating which neighbor cells are synchronous or asynchronous with a serving cell may allow a UE to determine whether it can derive neighbor cell RS timing based on the serving cell timing.

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.
