Abstract: Wireless communication devices, systems, and methods relate to selecting transmission parameters that optimize a dimension (e.g., time, frequency, and/or spatial) under a set of constraints. A UE may receive a resource allocation mode indication and a traffic parameter indication from a BS. The resource allocation mode indication informs the UE to optimize along a time dimension, a frequency dimension, and/or a spatial domain. The traffic parameter indication informs the UE what constraints to consider for the transmission parameters. The UE may use this information upon receipt of a reference signal in selecting transmission parameters based on the received reference signal, resource allocation mode indication, and traffic parameter indication. The resource allocation mode may correspond to optimization within a single slot or across multiple slots. Once selected, the UE may transmit the transmission parameters to the BS for use in sending the message to the UE.

Numerous other aspects are provided.

Abstract: In some aspects, multi-slot transport block (TB) configurations for communicating data between wireless devices, such as between a base station and a user equipment (UE), in a wireless communication system are described.

In such examples, the wireless device transmitting the large file may utilize a multi-slot TB including multiple TB segments corresponding to respective slots of a transmission. Similarly, a wireless device receiving the large file may utilize the multi-slot TB configuration for receiving the data.

Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: A two stage scrambling design is provided for generating and decoding Resource Spread Multiple Access (RSMA) modulated streams. A User equipment (UE) scrambles each data stream of a set of data streams using a first scrambling sequence to generate a first set of scrambled data streams, and then scrambles the first set of scrambled data streams using a second scrambling sequence to generate a second set of scrambled data streams, wherein the second scrambling sequence is longer than the first scrambling sequence. The UE then transmits the second set of scrambled data streams. A receiving base station determines the first and second scrambling sequences used by the UE and decodes the transmissions received from the UE based on the determined scrambling sequences.

The base station communicates with a UE using periodic uplink traffic bursts and periodic downlink traffic bursts. The base station selects a time offset to at least one of uplink traffic or downlink traffic to increase an overlap between the uplink traffic bursts and the downlink traffic bursts. The base station sends the time offset to an AF.

Abstract: Methods, systems, and devices for wireless communications are described that provide for acknowledging receipt of a transmission, or triggering a retransmission, based on an initial decoding or measurement of the transmission. A user equipment (UE) may receive a downlink transmission and perform initial decoding or a measurement on the downlink transmission to determine an initial feedback for the downlink transmission. The initial feedback may be provided to a base station in a first set of uplink resources configured for initial feedback transmissions. The base station may receive the initial feedback, and may initiate a retransmission of the downlink transmission before a final feedback determination is made at the UE. In cases where a UE transmits an uplink transmission, the base station may perform initial decoding and may allocate retransmission resources to the UE prior to completing a final decoding of the uplink transmission.

Abstract: Some wireless communication systems may attempt to balance frequent transmission opportunities (e.g., where the frequency of the opportunities may refer to gaps in the time domain, frequency domain, etc.) with a desire for communication reliability and/or interference diversity. In accordance with the described techniques, some such systems may apportion communicating devices into groups, where resources are strategically assigned to each group so as to reduce latency without significantly compromising communication reliability or interference diversity (e.g., by allowing a membership of the groups to cycle through all possible combinations before repeating). Such techniques may support delay-sensitive communications, channel sounding procedures, or other similar types of transmissions. Resources may be allocated based on a scheduling parameter transmitted to a user equipment (UE), which may implicitly or explicitly indicate a plurality of resource offsets to the UE.

Abstract: Certain aspects of the present disclosure provide techniques for interference mitigation. Certain aspects provide a method for wireless communication. The method generally includes performing communications, in a first channel, on a first downlink in a first time period based on communications in a second channel adjacent to the first channel being performed on a second downlink in the first time period.

The method further includes refraining from communicating in the first channel on one or more resources in the first time period or the second time period to mitigate cross-link interference with a third channel adjacent to the first channel.
