Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may detect interference, in a remote interference management (RIM) scenario, in a set of sub-bands of a plurality of sub-bands of a bandwidth portion. The base station may transmit, to identify the set of sub-bands in which interference is detected, a set of reference signals configured to indicate the set of sub-bands in which the interference is detected. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that at least one condition, of a plurality of conditions, is satisfied with regard to at least one other base station; and perform at least one remote interference management (RIM) operation, the at least one RIM operation selected based at least in part on the at least one condition. In some aspects, a base station may receive an indication regarding interference, the indication regarding interference indicating that at least one condition, of a plurality of conditions, is satisfied with regard to the base station or at least one other base station; and perform at least one RIM operation, the at least one RIM operation selected based at least in part on the at least one condition or the indication regarding interference. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may apply one or more spreading sequences to a set of modulation symbols of a data set to generate spread modulation symbols; apply a scrambling sequence to the spread modulation symbols to generate a set of scrambled symbols; and transmit a waveform based at least in part on the set of scrambled symbols. Numerous other aspects are provided.

Abstract: Sequence selection techniques for Non-Orthogonal Multiple Access (NOMA) are provided. A User Equipment (UE) sends a request to a base station, the request indicating that the UE is to conduct at least one uplink transmission. The UE receives, in response to the request, an indicator of an expected system load, a value of the indicator including a total number of sequences expected to be used at one time for uplink transmissions in the system. The UE detects that at least two different pairs of sequences in a configured set of sequences have different cross correlation values, the sequences in the set configured for scrambling uplink transmissions. The UE selects, in response to the detecting and based on the indicator, at least one sequence with an improved cross correlation with at least one other sequence the at least one sequence and the at least one other sequence to be used for scrambling uplink transmissions within the system.
