Abstract: Methods, systems, and devices for wireless communications are described. Multiple component carriers may be configured for communications between communication devices, where uplink data channel resources may be scheduled on a component carrier of the component carriers. A communication device may report, over the uplink data channel resources to another communication device, a first report for available transmission power for uplink data transmissions over the component carrier and a second report associated with available transmission power for uplink control transmissions over a second component carrier. The other communication device may use the second report to determine the available transmission power for uplink control transmissions over the second component carrier. The other communication device may schedule communication resources based on the determined available transmission power for uplink control transmissions.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that provide a mechanism for managing a sequential order for performing a deferral procedure and at least one other slot index-dependent procedure in a wireless communication system. In particular aspects, a user equipment, UE, may be configured to perform a first slot index-dependent procedure and a deferral procedure of uplink repetitions. The UE may determine a sequential order for performing the deferral procedure and the first slot index-dependent procedure, and may then perform the deferral procedure and the first slot index-dependent procedure in the sequential order. The sequential order may include performing the deferral procedure before the first slot index-dependent procedure, performing the deferral procedure after the first slot index-dependent procedure, or a sequential order that is based on a type of procedure of the first slot index-dependent procedure.

Abstract: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first rate matching resource indication that indicates that a first rate matching resource is available for use by the UE in reception of a downlink shared channel. The UE may also receive a second rate matching resource indication that indicates that a second rate matching resource is not available for use by the UE in reception of the downlink shared channel. The UE may identify a rate matching resource indication conflict arising from an overlap of at least one resource element included in both the first rate matching resource and the second rate matching resource. The UE may then resolve the rate matching resource indication conflict in accordance with a conflict resolution rule.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more retransmissions of an initial group-common transmission. The UE may receive, in accordance with a first SPS configuration, a group-common transmission of a group-common downlink shared channel, the group-common transmission being associated with a first RNTI. The UE may transmit feedback information for the group-common transmission. The UE may then receive a downlink control information (DCI) message scheduling either a group-common retransmission of the group-common downlink shared channel or a unicast retransmission of the group-common downlink shared channel. The DCI may indicate that either the group-common retransmission is associated with the first RNTI or that the unicast retransmission is associated with a second RNTI that may be different from the first RNTI.

Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites or base stations, or both in a non-terrestrial network. Due to large distances between transmitting devices and receiving devices in a non-terrestrial network, the UE may account for propagation delay and frequency shift of communications with a satellite based on location information of the satellite. The UE may receive first satellite location information from a base station or a satellite, via a broadcast message. The UE may receive second satellite location information from the wireless network node via a unicast message, where both the first satellite location information and the second satellite location information relate to a same satellite. The UE may transmit an uplink communication via the satellite based on at least one of the first satellite location information or the second satellite location information.

Abstract: Certain aspects of the present disclosure provide techniques for adaptive modulo base selection for non-linear precoding. Aspects provide a method for wireless communications that can be performed by a base station (BS). The BS adaptively selects a modulo base for a data stream for at least one user equipment (UE) in a transmission to one or more UEs. The BS selects the modulo base based on one or more parameters. The BS transmits a signal for at least one UE of the one or more UEs to identify the selected modulo base. The BS performs the transmission to the one or more UEs. The UE receives the transmission from the BS and the signal for the identification of the selected modulo base. Based on the signal, the UE determines the modulo base for at least one data stream in the transmission and decodes the data stream using the modulo base.

Abstract: Techniques for monitoring for control information in sets of downlink control channel resources are described, where multiple sets of downlink control channel resources may overlap. The described techniques include monitoring for one or more search spaces in a set of downlink control channel resources by rate matching downlink control channel resources independently of other sets of downlink control channel resources. Alternatively, overlapping sets of downlink control channel resources may be rate-matched accounting for reference signals of overlapping sets of downlink control channel resources.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmission continuity capability reporting. A user equipment (UE) may generate or otherwise determine UE capability information related to a capability of the UE to maintain a transmission continuity for one or more uplink transmissions across a wireless channel. The UE may send an indication of the transmission continuity capability information, which may be based on a parameter of continuity, an accuracy of continuity, or both, to a base station (BS). The UE may transmit the one or more uplink transmissions, including reference signals, data messages, or both, in accordance with the transmission continuity capability. For example, the UE may maintain a transmission continuity, a transmit power, or both for transmissions across multiple resource blocks (RBs). The BS may perform a joint channel estimation procedure based on the one or more uplink transmissions.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of a set of linked physical downlink control channel (PDCCH) candidates if the UE selects to monitor a subset of the linked PDCCH candidates. In one aspect, the UE may monitor the subset of the linked PDCCH candidates, and the UE and the component of the BS may select a reference PDCCH candidate from which to define scheduling information in accordance with the UE monitoring the subset of the linked PDCCH candidates. In some examples, the UE and the component of the BS may select the reference PDCCH candidate in accordance with one or more mutually understood rules or procedures such that the UE and the component of the BS may select a same reference PDCCH candidate.
