Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a search space configuration for a scheduled cell of the UE based at least in part on one or more active bandwidth parts of the UE, wherein the UE is associated with a scheduling cell, and wherein the one or more active bandwidth parts are associated with at least one of one or more first bandwidth part configurations of the scheduling cell or one or more second bandwidth part configurations of the scheduled cell; and receive information based at least in part on the search space configuration. Numerous other aspects are provided.

Abstract: Systems and methods configured to provide size matching of downlink control information (DCI) formats to restrict a number of DCI format sizes for a set of DCI formats for concurrent use are described. In accordance with embodiments of the present disclosure, size matching at least two DCI formats of a set of DCI formats to restrict a number of DCI format sizes for the set of DCI formats for concurrent use is implemented. Restrictions with respect to the number of DCI format sizes for the set of DCI formats may correspond both to a first number of DCI sizes parameter based on a total number of DCI format sizes per wireless communication slot, and to a second number of DCI sizes parameter based on a total number of DCI format sizes for DCI formats used to carry DCI payload encoded using an identifier per wireless communication slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify a hash value index associated with searching for a physical downlink control channel. The hash value index may be identified based at least in part on an index of an interval of a plurality of intervals within a periodicity. The user equipment may configure, based at least in part on the hash value index, a hash function associated with determining the hash value. Numerous other aspects are provided.

Abstract: A method an apparatus and a computer program product for wireless communication are provided in which a set of time intervals is obtained from a received radio frequency signal. A power profile is determined for a frequency spectrum segment in each time interval. A first list is used to identify frequency spectrum segments that exhibit a power or energy profile over a range of frequencies associated with a downlink channel bandwidth and a second list is used to identify frequency spectrum segments that have a total or average energy greater than a threshold energy relative to a noise floor. An absolute radio frequency channel number (ARFCN) of a wireless communication system is determined based on the frequency spectrum segments identified in the first and second lists.

Abstract: Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows. Semi-uniform pilot spacing in both the frequency and time domains can be utilized. In time domain, a first pilot symbol pair is spaced by a first time interval and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.
