Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication that a set of occasions for a message occurs over multiple symbols. The multiple symbols may include a set of full-duplex symbols and a set of half-duplex symbols. The UE may select one or more resources for communicating the message via a first occasion of the set of occasions in accordance with a set of rules and based on the first occasion being included in a first slot type or a second slot type. The first slot type may correspond to one or more half-duplex symbols of the set of half-duplex symbols and the second slot type may correspond to one or more full-duplex symbols of the set of full-duplex symbols. The UE may communicate the message using the one or more selected resources.

Description

CROSS REFERENCE The present application for patent claims the benefit of U.S. Provisional Patent Application No. 63/485,125 by MONDET et al., entitled “MULTIPLE TRANSMISSIONS WITH SUBBAND FULL-DUPLEX OPERATION,” filed Feb. 15, 2023, assigned to the assignee hereof, and expressly incorporated by reference herein. FIELD OF TECHNOLOGY The following relates to wireless communications, including multiple transmissions with subband full-duplex operation. BACKGROUND Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE). In some wireless communications systems, a network entity may schedule multiple transmissions at a UE. The network entity may schedule the multiple transmissions in accordance with a subband full-duplex operation. SUMMARY The described techniques relate to improved methods, systems, devices, and apparatuses that support multiple transmissions with subband full-duplex (SBFD) operation. For example, the described techniques provide for a set of rules that modifies scheduling of a message that includes multiple transmissions at a user equipment (UE). In some examples, the UE or a network entity may select resources for communicating the message based on the set of rules indicating that the multiple transmissions of the message are scheduled on a same slot type. The network entity may schedule each of the multiple transmissions of the message on slots configured with SBFD or may schedule each of the multiple transmissions of the message on slots not configured with SBFD. That is, the set of rules may indicate that the network entity is to schedule the multiple transmissions of the message in non-consecutive slots. In other examples, the set of rules may indicate that the network entity is to modify scheduling of subsequent transmissions of the message based on a first transmission of the message occurring in a specified slot type (e.g., configured with SBFD, not configured with SBFD). For example, the network entity may perform a frequency shift on the subsequent transmissions of the message and may indicate the frequency shift to the UE. A method for wireless communication at a user equipment (UE) is described. The method may include receiving an indication that a set of occasions for a message occurs over a set of multiple symbols, where the set of multiple symbols includes a set of full-duplex symbols and a set of half-duplex symbols, selecting one or more resources for communicating the message via a first occasion of the set of occasions in accordance with a set of rules and based on the first occasion being included in a first slot type or a second slot type, the first slot type corresponding to one or more half-duplex symbols of the set of half-duplex symbols and the second slot type corresponding to one or more full-duplex symbols of the set of full-duplex symbols, and communicating the message using the one or more selected resources. An apparatus for wireless communication at a UE is described. The apparatus may include a processor and a memory coupled with the processor. The memory may include instructions executable by the processor to cause the apparatus to receive an indication that a set of occasions for a message occurs over a set of multiple symbols, where the set of multiple symbols includes a set of full-duplex symbols and a set of half-duplex symbols, select one or more resources for communicating the message via a first occasion of the set of occasions in accordance with a set of rules and based on the first occasion being included in a first slot type or a second slot type, the first slot type corresponding to one or more half-duplex symbols of the set of half-duplex symbols and the second slot type corresponding to one or more full-duplex symbols of the set of full-duplex symbols, and communicate the message using the one or more selected resources. Another apparatus for wireless communication at a UE is described. The apparatus may include means for receiving an indication that a set of
