Abstract: Aspects provide a mechanism for activating a secondary serving cell (SCell) in a wireless communication network supporting a multi-cell transmission environment. In some examples, a scheduled entity (e.g., a UE) in a connected mode with a primary serving cell (PCell) may synchronize with the SCell to activate the SCell for multi-cell communication with the PCell and the SCell. To enable synchronization with the SCell, the PCell may trigger communication and processing of one or more reference signals between the scheduled entity and the SCell.

Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A scheduled entity (e.g., a user equipment (UE) or child integrated access backhaul (IAB) node) may observe a change in the downlink reception timing of downlink signals transmitted from a scheduling entity (e.g., a base station or parent IAB node). The scheduled entity may then autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. In addition, the scheduled entity may further maintain the same downlink transmission timing irrespective of the change in downlink reception timing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a control channel, control information that provides an indication to skip monitoring of the control channel for a time duration. The UE may monitor the control channel according to the control information. Numerous other aspects are provided.

Abstract: In an embodiment, a base station determines a spatial relationship for a group of PUCCH resources, and transmits a control message that indicates the spatial relationship to a UE. The UE receives the control message and stores an indication of the spatial relationship. In some designs, the control message conveying the spatial relationship identifies the group of PUCCH resources via the PUCCH group index, while in other designs a different identification mechanism may be used. In another embodiment, a base station determines an association between a group of PUCCH resources and a PUCCH group index, and transmits a control message that indicates the association to a UE. The UE receives the control message and stores an indication of the association.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may determine a mobility state. The network node may determine a communication configuration, selected from a plurality of communication configurations associated with a plurality of mobility states, based at least in part on the mobility state. The network node may perform a communication procedure using the selected communication configuration. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure are regarding configuring an Integrated Access and Backhaul (IAB) node of an IAB network to handle forwarding of packets from another device as well as packets originating in the IAB network at the IAB-node. An example method includes retrieving, by a Backhaul Adaptation Protocol (BAP) layer of the IAB-node, a packet from an upper layer or a Radio Link Control (RLC) layer of the IAB-node. The method also includes determining an egress RLC channel of an egress backhaul (BH) link with a second device for transmitting the first packet based on a first configuration in response to retrieving the first packet from the RLC layer or a second configuration in response to retrieving the first packet from the upper layer. The method also includes transmitting the first packet to the second device via the egress RLC channel of the egress BH.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may measure a first reference signal, associated with a frequency band of a long term evolution (LTE) system, and a second reference signal associated with a frequency band of a new radio (NR) system. The frequency band of the NR system may overlap the frequency band of the LTE system. The UE may determine first channel state feedback, associated with the frequency band of the LTE system, and second channel state feedback, associated with the frequency band of the NR system, based at least in part on the first reference signal and the second reference signal, respectively. The UE may report the first channel state feedback or the second channel state feedback in uplink control information (UCI). Other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to system information acquisition over bandwidth parts (BWPs) in communications system operating according to new radio (NR) technologies. In an exemplary method, a user equipment (UE) receives system information (SI) via a transmission in a downlink (DL) bandwidth part (BWP) of a system bandwidth and transmits, to a serving base station (BS) and in response to receiving the SI, an indication that the UE has completed SI acquisition.

Abstract: Aspects relate to a physical cell identifier (PCI) change within a wireless network based on a primary synchronization signal (PSS) waveform. A scheduling entity, such as an integrated-access-backhaul (IAB) node within a radio access network (RAN), may communicate with a set of one or more scheduled entities, such as other IAB nodes and/or user equipment (UEs), utilizing a first PCI. The scheduling entity may then change from the first PCI to a second PCI, where the second PCI corresponds to a different PSS waveform than the first PCI. In some examples, the scheduling entity may change the PCI as a result of a PCI collision and/or PSS collision with a neighboring scheduling entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a first set of resources for an access link communication between the first UE and a base station. The UE may identify a second set of resources for a sidelink communication between the first UE and a second UE. The UE may identify a scheduling conflict between the first set of resources for the access link communication and the second set of resources for the sidelink communication. The UE may drop at least a portion of the first set of resources for the access link communication or the second set of resources for the sidelink communication based at least in part on the identification of the scheduling conflict and a prioritization rule. Numerous other aspects are provided.
