Abstract: Methods, systems, and devices for wireless communications are described and may include a user terminal and a satellite establishing a communication link over a channel having a channel delay and a medium access control-control element (MAC-CE) delay being determined based on the channel delay. The user terminal and the satellite may be within a non-terrestrial network (NTN). The user terminal may receive a MAC-CE command that indicates a communication parameter to be implemented or adjusted. The user terminal may transmit feedback, for example, to the satellite in response to the MAC-CE command, and the user terminal and the satellite may communicate according to the communication parameter in the MAC-CE command after an end of the MAC-CE delay.

Abstract: Disclosed are techniques for paging a user terminal (UT) in a non-terrestrial network (NTN), which may define a plurality of NTN tracking areas (TA). Each NTN TA, served by one or more satellite beams, may move or may be a geographic region. The UT may report its location before changing its connection state with the NTN and may also update its location whenever it moves a threshold distance from the previous reported location. The NTN may estimate UT's current location based on the last reported location and other factors including mobility of the UT. The NTN may determine a UT TA as the NTN TA that corresponds to the current location, and may page the UT through one or more satellite beams corresponding to the UT TA.

Abstract: Certain aspects of the present disclosure relate generally to wireless communications systems, and more particularly, to techniques that may help reduce or eliminate ambiguity in acknowledging multiple physical downlink shared channel (PDSCH) transmissions in a single transmission time interval (TTI). According to aspects, a codebook with fewer fields than a number of PDSCH candidates may be used to provide acknowledgement/negative acknowledgement (ACK/NACK) feedback.

Abstract: In some aspects, a user equipment (UE) may receive a configuration from a base station that indicates whether to use a first channel quality indicator (CQI) table from a first set of CQI tables associated with terrestrial network communications or whether to use a second CQI table from a second set of CQI tables associated with non-terrestrial network communications. The UE may transmit CQI feedback to the base station based at least in part on the configuration. The UE may transmit the CQI feedback using the first CQI table when the configuration indicates that the first CQI table is to be used or may transmit the CQI feedback using the second CQI table when the configuration indicates that the second CQI table is to be used.

Abstract: Control channel decoding can consume a significant amount of power with respect to the device's total power battery lifetime, as well as being a factor in the complexity of device. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of control channel decoding complexity and power requirements by improving the manner in which control channels are decoded. An apparatus configures an initial CORESET having a reduced bandwidth corresponding to a bandwidth capability of a first UE type. The reduced bandwidth having a narrower frequency range than a bandwidth capability of a second UE type. The apparatus may configure a first CORESET for a first UE having a first bandwidth capability and a second CORESET for a second UE having a second bandwidth capability. The apparatus transmits control channel(s) in the configured CORESET(s).

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: Methods, systems, and devices for configuring physical downlink control channel candidates are described. The method may include monitoring, by a UE, an initial set of physical downlink control channel candidates in a first slot, receiving, by the UE, an indication of an adjusted set of physical downlink control channel candidates to monitor in a second slot based on decoding a physical downlink control channel candidate in the initial set, and monitoring, by the UE in the second slot, the adjusted set of physical downlink control channel candidates. The method may also include adaptively (e.g., autonomously) determining, by the UE, the adjusted set of physical downlink control channel candidates, and corresponding determinations by the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a resource configuration for communications with a base station on a multiple sets of resources across multiple component carriers, the resource configuration including at least a first set of resources on a first component carrier and a second set of resources on a second component carrier. The UE may receive, from the base station, a downlink control information (DCI) message on the first component carrier, the DCI message including a DCI format that controls the multiple of sets of resources across the plurality of component carriers. The UE may determine that the first set of resources and the second set of resources are one of activated or released based on a first indication in the DCI message.
