Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that indicates a configuration for subband full duplex (SBFD) slots and a random access channel (RACH) configuration for SBFD slots. The UE may transmit at least one instance of a RACH message in an uplink subband of an SBFD slot in accordance with the RACH configuration. The RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across an SBFD slot and an uplink slot. The RACH configuration may map synchronization signal blocks (SSB)s to RACH occasions in the uplink subband of the SBFD slot. In some examples, the SSBs may be mapped across multiple (e.g., consecutive) SBFD slots. In some cases, the RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across multiple SBFD slots.

Abstract: MAC-CE based dynamic MCS tables switching is introduced to support addition of higher modulation orders and new constellation types. First, a UE receives a RRC configuration indicating a plurality of MCS tables. Next, the UE receives a MAC CE activating a MCS table among the plurality of MCS tables. Doing so allows MCS tables to be dynamically switched via a MAC-CE based activation/reactivation adaptive to current signal to noise (SNR)/spectral efficiency (SPEF) experienced in a downlink and uplink. Finally, the UE communicates data with a base station using a MCS in the activated MCS table.

Abstract: To enable full-duplex communication in a time division duplexing (TDD) band, a network node (e.g., a user equipment (UE)) may be configured to communicate in one or more flexible bandwidth parts (BWPs) using BWP-specific TDD patterns regardless of a TDD pattern configured for the underlying band. However, in some cases, half-duplex communication may offer better performance than full-duplex communication (e.g., when full-duplex communication may cause self-interference or there is a need for high throughput half-duplex communication). Accordingly, some aspects described herein relate to timing considerations and switching indications for indicating an interval in which the network node is to operate in the flexible BWP using the BWP-specific TDD pattern and switching between the BWP-specific TDD pattern and the TDD pattern of the underlying band (e.g., using switching indications based on a number or quantity of transmission time intervals and/or a timer, among other examples).

In a wireless communications system, a user equipment (UE) may use partial frequency sounding with different frequency subhop patterns so that a portion (which may be referred to as a subhop) of configured sounding reference signal (SRS) resources (e.g., a hop) are sounded.

As such, the network entity may configure a repetition factor for the frequency subhop pattern. In some cases, the frequency subhop pattern may introduce a frequency overlap between subhops.
