Abstract: Techniques are provided for Wake up signal monitoring in a radio resource control connected (RRC) mode. An example method can include a base station receiving an indication from a user equipment (UE) of a capability for wake-up signal (WUS) monitoring in a radio resource control (RRC) connected mode while in a sleep state. The base station can configure the UE with a first frequency domain resource for WUS monitoring in the RRC connected mode while in the sleep state. The base station can transmit a WUS using the first frequency domain resource and a first time domain resource, wherein a main radio of the UE is configured to transmit and receive based on the WUS. The base station can transmit a first downlink (DL) transmission.

Abstract: A communication system provides reliable wideband communications with reduced power consumption in a user equipment (UE) receiver. A UE may include receiver circuitry to receive a radio frequency (RF) signal from a wireless network and output an analog baseband signal. The RF signal includes M copies of a duplicated signal in a frequency domain. The analog baseband signal includes the M copies of the duplicated signal uniformly offset from one another in the frequency domain by a bandwidth F and including a gap between adjacent copies. The UE further includes an anti-aliasing analog filter an analog to digital converter (ADC). The ADC samples an output of the anti-aliasing analog filter at a sampling frequency selected to obtain a digital baseband signal comprising a combined digital copy of the M copies of the duplicated signal folded over each other.

Abstract: This disclosure relates to techniques for signaling a quasi-colocation (QCL) update in a wireless communication system. A network or base station may indicate to a UE to change a spatial relationship for transmission/reception. The base station may provide aperiodic reference signals for the UE to use in beam tracking according to the new spatial relationship. Optionally, the base station may also provide aperiodic reference signals for time, frequency, and/or phase tracking. Thus, the network may configure the UE to change to the new spatial relationship and use the aperiodic reference signals to quickly complete initial tracking operations.

Abstract: Apparatus and methods are provided to enhance communications for NTN. In some aspects, a base station (BS) comprises a processor configured to schedule an uplink transmission in response to an uplink transmission request from a user equipment (UE) using one or more subframes ranging from a first uplink subframe to a last uplink subframe. The processor is further configured to determine or receive a timing advance (TA) indicating amount of subframes transmitted during a time delay between the UE and the BS and schedule a downlink transmission aligned with the uplink transmission. The downlink transmission is blocked from subframes ranging from TA plus one or more subframes ahead of the first uplink subframe to TA minus one or more subframes ahead of the last uplink subframe. The processor is further configured to transmit and receive, via a non-terrestrial equipment, the uplink and the downlink.

Abstract: A cellular base station (BS) which transmits more flexible downlink control information (DCI) to the UE, and a UE capable of receiving and processing a received DCI message. The DCI message may have a DCI format of 0_1 or 0_2 and further may comprise an UL-SCH set to 0, a CSI request field of all 0s and an SRS request field having a nonzero value. The DCI message may indicate to the UE that the UE should: 1) transmit an aperiodic SRS corresponding to SRS request; and 2) that the UE should not transmit on the PUSCH. The DCI may include existing fields that specify either a slot offset or beam information useable when transmitting the aperiodic SRS. The base station may also generate a DCI message with an SRS trigger that is targeted to a plurality of UEs in a group, or a plurality of groups of UEs, for greater efficiency.

Abstract: A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.

Abstract: Uplink transmissions of a mobile device (UE) may be improved in a number of ways. Uplink Transmission Time Interval (TTI) bundling, including both Type-A and Type B PUSCH repetitions, may be implemented with variable TTI bundle sizing. The TTI bundle size may be determined by a base station and communicated to the UE explicitly, or may be determined by the UE implicitly, based on an indicated repetition number and frequency hopping number. The UE may also report frequency hopping (FH) assist information to the base station for use by the base station to more efficiently configure FH for the uplink transmissions. Finally, the UE may use (or maintain) the same transmission power, for each TTI transmit occasion of the same TTI bundle in order to improve (cross-slot) channel estimation accuracy. Power allocation may be prioritized to ensure that at the same time a total power for the uplink transmissions of the UE does not exceed a specified threshold.

Abstract: Systems and methods for using hybrid automatic repeat request acknowledgement (HARQ-ACK) codebooks to as part of acknowledgement/negative acknowledgement (ACK/NACK) signaling regarding multiple physical downlink shared channel (PDSCH) transmissions (also termed “multi-PDSCH”) scheduled by a single downlink control information (DCI) corresponding to multiple candidate PDSCH monitoring occasions are discussed herein. Rate matching indicators for one, multiple, or all of the PDSCHs of a scheduled multi-PDSCH are discussed. Effects of invalid symbol signaling, where one or more resources corresponding to a candidate PDSCH monitoring occasion corresponding to the DCI has been indicated for uplink (UL) use or not for DL use by a base station, are discussed. Effects of a bandwidth part change (in UL or downlink (DL)) occurring near or during the DCI, the multi-PDSCH, and a physical uplink control channel (PUCCH) containing the ACK/NACK signaling (e.g., containing or corresponding to all or part of the HARQ-ACK codebook) are discussed.

Abstract: Techniques described here related to a power headroom power headroom report generation trigger. One aspect of the disclosure includes a user equipment (UE) configured to measure a first path loss change of a first physical uplink shared channel (PUSCH) transmission transmitting from the first antenna panel to a first transmission and reception point (TRP). The UE can further measure a second path loss change of a second PUSCH transmission transmitting from the second antenna panel to a second TRP, the second PUSCH transmission transmitting simultaneously to the first PUSCH transmission. The UE can further determine whether to generate a powerhead report (PHR) based on the measured first path loss change and measured second path loss change. The UE can further generate the PHR based on the determination.
