Abstract: User Equipment (UE) receives, from a base station (BS), at least one resource block (RB). The RB includes at least one reference signal (RS) resource element (RE) of a first physical channel of the UE. The UE estimates a channel quality of a second physical channel of the UE as a function of the at least one RS RE. In some examples, the BS associates the transmission of a first physical channel reference signal (RS) and the transmission of a second physical channel RS. The BS then signals, BS to the UE, the association between the first physical channel reference signal and the second physical channel reference signal.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission power for an uplink shared channel communication based at least in part on at least one of a code rate parameter, a block length parameter, or a target block error rate parameter associated with the uplink shared channel communication. In some aspects, the user equipment may transmit the uplink shared channel communication using the transmission power based at least in part on determining the transmission power. Numerous other aspects are provided.

Abstract: Some aspects of the present disclosure disclose methods and systems related to separate and joints releases of semi-persistent scheduling (SPS) configured transmission occasions by an SPS release. For example, a user equipment (UE) may receive, from a base station (BS) and via a physical downlink control channel (PDCCH), a semi-persistent scheduling (SPS) release configured to jointly release at the UE a plurality of SPS configurations, each SPS configuration of the plurality of SPS configurations configured to schedule one or more SPS physical downlink shared channel (PDSCH) transmission occasions of a plurality of SPS PDSCH transmission occasions. In some instances, the plurality of SPS PDSCH transmission occasions may occur in a same slot as the SPS release. Further, the UE may not expect to receive, or refrain from receiving, SPS PDSCH via the plurality of SPS PDSCH transmission occasions.

Abstract: Apparatus, methods, and computer program products for flexible uplink transmission are provided. An example method may include receiving a configuration of resources for a PUCCH or a PUSCH associated with UCI, where the configuration of resources may be received from a network entity, where the UCI indicates a set of resources corresponding to a transmission in a first subset of resources associated with the PUSCH and a skipped transmission in a second subset of resources associated with the PUSCH or indicates an MCS for the PUSCH, where the UCI would overlap with an uplink transmission, where the set of resources may include the first subset of resources and the second subset of resources. The example method may further include transmitting at least one of the UCI or the uplink transmission to the network entity.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A user equipment (UE) may receive a first data message in a sub-slot of a slot and in a sub-channel of a sidelink data channel. The UE may select a resource of a sidelink feedback channel based on a first index associated with the slot and a second index associated with the sub-slot within one or more slots comprising the slot. Additionally or alternatively, the UE may select a resource of a sidelink feedback channel from periodic resources having a slot-based periodicity based on an index associated with the sub-slot within one or more slots comprising the slot. The UE may transmit a feedback message associated with the first data message according to the selected resource.

Abstract: Wireless communication devices, systems, and methods related to bundling of uplink communication signals under timing advance (TA) conditions are provided. For example, a method of wireless communication performed by a user equipment can include receiving, from a base station, a timing advance (TA), wherein the TA is scheduled to be implemented by the user equipment at a first time, the first time being after a start of a first uplink communication of a group of bundled uplink communications scheduled with phase coherence and before a start of a second uplink communication of the group of bundled uplink communications; determining whether to implement the TA at the first time or a second time, the second time being after transmission of the second uplink communication; and implementing the TA based on the determining.

Abstract: Techniques for supplementary sidelink resource configuration in full duplex mode may include a first user equipment (UE) transmitting to a base station an interference report indicating sidelink communication interference. The base station may select a resource pool according to the interference report, where the resource pool includes supplementary sidelink subchannels reserved for receiving sidelink communications and conditionally reserved for transmitting sidelink communications based on the interference report. The base station may transmit, to the first UE or a second UE causing the sidelink communication interference, configuration information indicating the resource pool. Based on the configuration information, the first UE and/or the second UE may perform sidelink communications (with each other or with other UEs) using the supplementary sidelink sub channels.

Abstract: Aspects relate to a base station configuring a user equipment (UE) with multiple (e.g., at least two) hybrid automatic repeat request (HARQ) feedback granularities. In some examples, a first HARQ feedback granularity may be for transmitting HARQ feedback in a first quantity of symbols and a second HARQ feedback granularity may be for transmitting HARQ feedback in a second quantity of symbols. The base station may send an indication to the UE that specifies which HARQ feedback granularity the UE is to use for sending HARQ feedback.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.
