Abstract: The described techniques provide for efficiently monitoring for control information from a single transmission-reception point (TRP) after transitioning from a multi-TRP operation mode to a single-TRP operation mode. If a user equipment (UE) is communicating with a first TRP and a second TRP in a multi-TRP operation mode, and the UE is directed to transition to communicating with the first TRP in a single-TRP operation mode, the UE may limit the number of CORESETs monitored in the single-TRP operation mode to a maximum number of CORESETs configured for the single-TRP operation mode. That is, if the number of CORESETs monitored by the UE for control information from the first TRP in the multi-TRP mode exceeds the maximum number of CORESETs configured for the single-TRP operation mode, the UE may identify a subset of the CORESETs to monitor for control information from the first TRP in the single-TRP mode.

Abstract: A user equipment (UE) may receive a downlink control information (DCI) including an antenna port field and a transmission configuration indication (TCI) field for scheduling a physical downlink shared channel (PDSCH). The TCI field may indicate that two or more reference signals apply to two or more demodulation reference signal (DMRS) ports across all resource blocks and symbols for the PDSCH for at least one transmission layer of the PDSCH. The antenna port field may indicate a plurality of indicated DMRS ports. The UE may map two or more DMRS ports of the indicated DMRS ports to at least one transmission layer of the PDSCH. The UE may receive the at least one transmission layer of the PDSCH as a single-frequency-network (SFN) transmission based on the two or more reference signals and the two or more DMRS ports.

Abstract: A base station transmits a first downlink control information (DCI) portion in a physical downlink control channel (PDCCH), wherein the first DCI portion indicates a second DCI portion. The base station jointly encodes multiple component DCIs, each of the component DCIs providing a resource allocation in combination with the first DCI portion. The apparatus transmits the second DCI portion comprising the jointly encoded multiple component DCIs in a physical downlink shared channel (PDSCH).

Abstract: Wireless communications systems and methods related to communicating in a communication medium are provided. A base station (BS) receives from a user equipment (UE), feedback information of the UE. The BS determines a schedule for the UE. The schedule includes a scheduling duty cycle based on the feedback information of the UE. The BS communicates with the UE, a communication signal based on the schedule.

Abstract: PDSCH and PUSCH repetition enhancements are disclosed. A UE may determine configuration data (e.g., transmission parameters, and/or RV data) for PDSCH/PUSCH repetitions which are split across a slot transition within a slot or across a slot boundary based on a quantity of nominal repetitions indicated by a downlink control message (e.g., a downlink control information signal). A quantity of actual repetitions (e.g., splitting of one or more nominal repetitions) may be identified based on the quantity of nominal repetitions and slot configuration parameters. In some aspects, a UE determines a sequence of configuration data for nominal repetitions and generates a second sequence of configuration data for actual repetitions based on the sequence. In other aspects, a UE determines a single sequence of configuration data for actual repetitions based on the quantity of actual repetitions determined from the quantity of nominal repetitions indicated by the downlink control message.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a base station or a user equipment, may identify an energy detection threshold for a sensing beam associated with a channel access procedure, such as a listen-before-talk (LBT) procedure. The wireless device may also identify a set of transmit power parameters for one or more transmit beams. The wireless device may determine a degree of overlap between a beam shape of one or more transmit beams and a beam shape (e.g., a coverage area) of the sensing beam. The wireless device may adjust the set of transmit power parameters, the energy detection threshold, or a combination thereof based on the degree of overlap. The wireless device may perform the channel access procedure based on the determining, the adjusting, or both.

Abstract: Methods, systems, and devices for time domain single carrier (SC) waveform communications are described. A user equipment (UE) may generate an SC waveform by resampling (e.g., up-sampling) mapped information bits prior to insertion of a cyclic prefix (CP) or guard interval (GI). Performing resampling prior to CP/GI insertion allows for resource allocation flexibility and a base station may allocate resources for the SC waveform in accordance with this flexibility. For example, a base station may not be limited or restricted to a certain number of resources for SC waveform communications and may therefore determine a resource allocation for the UE based on the capability of the UE to perform resampling prior to CP/GI insertion. The resampling may be performed according to a set of parameters including a resampling ratio, which may be indicated to the UE via control signaling (e.g., from the base station).
