Abstract: Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer readable mediums for determining, such as by a user equipment (UE), a bundle size for demodulation reference signal (DMRS) bundling for an uplink random access channel (RACH) message sent with repetition and transmitting the uplink RACH message with DMRS bundling according to the determined bundle size. For example, in some aspects of the present disclosure, the uplink RACH message is sent with a number of repetitions and the bundle size is determined as a function of the number of repetitions. In some aspects, the bundle size is determined based on operation band. In some aspects, the bundle size is determined, based on a duplexing mode in which the UE is operating. In some aspects, the bundle size is determined, at least in part, based on signaling from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may configure a user equipment (UE) to perform demodulation reference signal (DMRS) enhancement whereby the UE may transmit physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) repetitions with different DMRS densities (e.g., a first DMRS density configuration having a first or default DMRS pattern within a transmission time interval (TTI) that is higher than a second DMRS density configuration having fewer DMRSs than the normal DMRS pattern or no DMRSs within the TTI). The UE may identify TTIs (e.g., slots) that satisfy one or more phase continuity rules, and may perform DMRS enhancement in the identified TTIs, and may restart a mapping sequence indicated in the DMRS mapping pattern at each bundle interval boundary or when consecutive uplink symbol periods within a bundling interval do not satisfy a phase continuity condition.

Abstract: Certain aspects of the present disclosure provide techniques for prioritizing overlapping or near overlapping uplink and downlink transmissions for a source base station (BS) and a target BS during a make-before-break handover of a user equipment (UE) from the source BS to the target BS.

Abstract: A base station may configure at least a first downlink transmission in a regular downlink burst with the first numerology for transmitting at least a portion of a data channel to a UE according to a numerology of a service used for data channel transmission. The base station also may configure at least a portion of a second downlink transmission in a regular downlink burst with a second numerology for transmitting a synchronization signal to the UE. A UE that receives the downlink regular burst may demodulate and decode the symbols in the received transmissions according to the numerology associated with each symbol.

Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

Abstract: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media, for a user equipment (UE) to determine and apply limits to physical downlink control channel (PDCCH) processing in a dual active protocol stack handover scenario. In one aspect, the UE utilizes a joint blind decode capability for both a source cell group and a target cell group to determine whether a total limit for PDCCH candidates to monitor or non-overlapped control channel elements (CCEs) to monitor is applicable. The UE may identify a per cell limit for each configured single transmit receive point (TRP) cell and each multiple TRP cell based on a sub-carrier spacing SCS of the cell and the determination. The UE may include an interface configured to obtain a PDCCH for a slot. The UE may perform blind decoding operations on CCEs up to the per cell monitoring limit for each cell.

Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods and apparatus for determining a target base station timing advance value between a user equipment (UE) and target base station in connection with a random access channel (RACH)-less handover procedure. In one aspect, the UE may determine the target base station's timing advance based at least in part on a timing difference between the target base station and the source base station and based at least in part on a timing offset associated with an uplink and a downlink of the UE. In some aspects, the target base station may determine the timing advance using an uplink reference signal of the UE. In some aspects, the UE may report a timing difference between the target base station and the source base station, and the source cell may determine a timing advance based at least in part on the timing difference.

Abstract: Certain aspects of the present disclosure provide techniques and apparats for remaining minimum system information (RMSI) physical downlink control channel (PDCCH) monitoring. A method for wireless communications by a user equipment (UE) is provided. During initial access of a cell, the UE determines a default first periodicity to monitor for at least a first PDCCH scheduling RMSI. After the initial access, the UE determines a second periodicity to monitor at least a second PDCCH scheduling RMSI based on the default first periodicity or based on an indication received in a previous RMSI from the cell. The UE monitors for at least the first PDCCH during initial access at the default first periodicity and monitors for at least the second PDCCH at the second periodicity after the initial access.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a remaining minimum system information control resource set (RMSI CORESET) monitoring configuration based at least in part on information received by the UE in a first frame; and monitor, during a second frame and based at least in part on the RMSI CORESET monitoring configuration, for an RMSI CORESET based at least in part on a synchronization signal block (SSB), associated with the RMSI CORESET, that is received in the first frame.
