Abstract: Aspects relate to dynamically changing the slot format of a slot between half-duplex and sub-band full-duplex and/or to changing flexible symbols within a flexible slot between half-duplex and sub-band full-duplex when a base station is configured to operate in a sub-band full-duplex mode. A slot format indicator (SFI) indicating the slot format of the slot may be signaled, for example, via downlink control information (DCI) mapped to a downlink control channel or medium access control (MAC) control element (MAC-CE) mapped to a downlink data channel. To improve reliability, various SFI boosting mechanisms may further be employed. For example, the base station may apply a higher aggregation level to the SFI, transmit repetitions of the SFI across multiple beams, apply a CRC enhancement and/or MCS enhancement to the downlink control channel carrying the SFI, and/or apply a power boost to the SFI.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to adjust a random access message that is transmitted to a base station in an asynchronous uplink transmission. The UE may use a constrained mapping of time and frequency resources for the random access message or transmit all portions of the message in a continuous transmission. The UE may also adjust the timing of the portions of the message. The base station may use a portion of the message, such as a preamble, to perform channel estimation for another portion of the message, such as a payload, to improve decoding of the transmitted message. Additionally, the UE may configure a waveform of the message to improve the continuous transmission of the message, for example by reducing interference between portions of the message.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support marking symbols and validation of non-cell-defining-synchronization signal block (NCD-SSB) and random access channel (RACH) occasions within 5G new radio (NR) networks. In a first aspect, a method of wireless communication includes the UE obtaining an uplink-downlink configuration for one or more slots, an NCD-SSB configuration identifying NCD-SSB transmissions, and a bandwidth configuration identifying a bandwidth part (BWP) allocated to the UE and a configuration for cell-defining-synchronization signal block (CD-SSB) transmissions. The UE can mark a configured flexible symbol as a downlink symbol in response to either an NCD-SSB symbol or a CD-SSB symbol overlapping with the flexible symbol. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating support for multiple configured grant small data transmission (CG-SDT) configurations and may receive one or more downlink messages that collectively indicate a downlink bandwidth part (BWP), an uplink BWP and a set of CG-SDT configurations based on transmitting the capability message. Each CG-SDT configuration may be associated with respective time and frequency resources for use in one or more CG-SDTs. The UE may transition out of a radio resource control (RRC) connected state based on receiving the one or more downlink messages. The UE may transmit an initial CG-SDT that includes a common control channel (CCCH) message using time and frequency resources associated with one or more of the set of CG-SDT configurations based on comparing the respective time and frequency resources associated with the each of the CG-SDT configurations.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) implement a timer (e.g., a round-trip time (RTT) timer) during which it does not monitor a physical downlink control channel (PDCCH). The UE may initiate the timer after transmitting a first random access message or a four-step random access message, or transmitting or retransmitting a third random access message of a four-step random access procedure, or after a physical uplink control channel (PUCCH) resource for hybrid automatic repeat request (HARQ) feedback for a fourth message of a four-step random access procedure. The UE may initiate the timer after transmitting a first message of a two-step random access procedure, or after a PUCCH resource for HARQ feedback for a second message of a two-step random access procedure, or after a fixed offset from the end of a PDSCH of a two-step random access procedure.

Abstract: An apparatus for wireless communication includes a transmitter configured to communicate with a base station based on a first uplink bandwidth part (BWP) that includes a first frequency subset and that further includes a second frequency subset. The apparatus further includes a receiver configured to receive, from the base station, one or more messages including a frequency hopping indicator that specifies whether a frequency hopping mode is enabled or disabled. The transmitter is further configured to transmit, to the base station, an uplink control channel transmission using both the first frequency subset and the second frequency subset based on the frequency hopping indicator specifying that the frequency hopping mode is enabled or using one of the first frequency subset or the second frequency subset based on the frequency hopping indicator specifying that the frequency hopping mode is disabled.

Abstract: Aspects described herein relate to physical downlink control channel (PDCCH) limits for multiple cells scheduling one cell in fifth generation new radio (5G NR). In an example, the aspects may include determining a PDCCH limit corresponding to at least one of a number of blind detections (BDs) and a number of control channel elements (CCEs) used for decoding PDCCH candidates for a first cell that schedules a second cell, and at least a third cell that schedules the second cell, wherein the third cell is the same cell as the second cell or the third cell is different from the second cell; and receiving one or more PDCCH transmissions from the first cell and the third cell based on the PDCCH limit.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for measuring, filtering, and reporting cross-link interference (CLI) in cases where not all aggressor user equipments (UEs) are transmitting signals that can be measured by a victim UE. A UE may obtain a set of CLI measurements by performing CLI measurements during a set of CLI measurement occasions. The UE may determine a first subset of the set of CLI measurements that satisfy a CLI measurement threshold and a second subset of the set of CLI measurements that do not satisfy the CLI measurement threshold. The UE may apply a filter to the first subset of the set of CLI measurements, and suppress the filter for the second subset of the set of CLI measurements, to obtain a filtered CLI measurement value. The UE may transmit the filtered CLI measurement value to a base station.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a first system information message including an indication of a resource configuration for a control resource set (CORESET) from a base station. The CORESET may include a common search space for a downlink control information (DCI) message that schedules a second system information message. The UE may identify a set of parameters from multiple sets of parameters for the CORESET based on the indication received in the first system information message and the UE being a first type of UE. The set of parameters may be different from a second set of parameters for the CORESET associated with a second type of UE different from the first type of UE. The UE may receive, in the CORESET according to the identified set of parameters, the DCI message scheduling the second system information message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, one or more control messages that indicate a configuration for a first downlink bandwidth part (BWP) associated with a first operating mode of the UE, a second downlink BWP associated with a second operating mode of the UE, a first set of resources within the first downlink BWP, and a second set of resources within the second downlink BWP. At least a portion of the configuration may correspond to a capability of the UE. The UE may monitor the first set of resources while in the first operating mode, and may monitor the second set of resources while in the second operating mode. The UE may receive a system information update or a public warning system (PWS) notification from the network entity via the second set of resources.
