Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit two or more connection requests prior to expiration of a UE connection response window. In some examples, the UE may re-set a UE connection response window each time the UE transmits a connection request. In some examples, the base station and UE may set their respective connection response windows after the UE transmits connections requests in a set of consecutive transmission opportunities. In some examples, the base station and UE may set their respective connection response windows based at least in part on a first available transmission opportunity. In some examples, the UE may include an indication of a position in a transmission sequence in the connection response, and the base station may set the UE connection response window based at least in part on the indication.

Abstract: Provided herein are various techniques and solutions to paging user equipment (UE). In particular, paging at higher levels of granularity, such as a beam level, for low mobility or stationary UEs in inactive and/or idle states are described. An apparatus may be configured to receive, from a network, a message configuring at least one beam notification area associated with positioning of the apparatus. The at least one beam notification area may include a set of beams corresponding to a set of cells identified by the network as candidates for carrying a paging message for the apparatus in the at least one beam notification area. The apparatus may be further configured to receive the paging message from the network via one of the set of beams corresponding to one of the set of cells in which the apparatus is positioned based on the at least one beam notification area.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a base station may support beamforming communication techniques and may communicate using one or more beams. The UE may support a bandwidth part (BWP) hopping pattern and may perform a beam failure detection (BFD) procedure across the supported BWPs. While performing the BFD procedure, the UE may declare beam failure and may determine whether to switch to an anchor BWP to initiate a beam failure recover (BFR) procedure or to remain on an active BWP to initiate the BFR procedure. In some implementations, the UE may determine whether to switch to the anchor BWP or to remain on the active BWP to initiate the BFR procedure based on an indication from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A semi-independent discontinuous reception (DRX) group configuration for a user equipment (UE) configured to communicate on at least a primary DRX group (PDG) and a secondary DRX group (SDG). The UE and a base station may implement a DRX coupling rule to ensure the PDG is in an active mode when the SDG is in an active mode. In some examples, the PDG, the SDG, or both may be configured for DRX long cycles, DRX short cycles, or both. The UE may determine active or inactive mode timers of each semi-independent DRX group. In some cases, the UE may trigger or extend an active mode of the PDG when an SDG active mode is triggered. Additionally, the UE may end an active mode of the SDG when an active mode of the PDG expires.

Abstract: Methods, systems, and devices for wireless communications are described. A first device (e.g., a relay user equipment (UE)) may establish a communication link, where the communication includes establishing a communication link between a second device (e.g., a remote UE) and a base station, the communication link including a first communication link between the second device and the first device and a second communication link between the first device and the base station. The first device may receive, over the first communication link, a transmission corresponding to data stored at the second device. The first device may receive, over the second communication link, an indication of one or more resources for a relay transmission corresponding to the data stored at the second device. The first device may transmit, over the second communication link, the relay transmission over the one or more resources based on receiving the sidelink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure resources on a first communication link for scheduling requests and may transmit an indication of the configured resources over a second communication link to a first device. The first device may relay the indication of the configured resources to a second device via the first communication link. The second device may identify that resources on the first communication link are unavailable for a transmission and may transmit a scheduling request. The first device may receive the scheduling request. The first device may transmit, over the first communication link and based on the scheduling request, an indication of one or more shared channel resources configured by the base station for the transmission. The first device may receive, over the first communication link, the transmission over the one or more shared channel resources.

Abstract: Methods, systems, and devices for wireless communications are described to support relayed sidelink communications. A first device and a base station may communicate via a communication link including a sidelink link between the first device and a second device and a relay link between the second device and the base station. The base station may determine restrictions for the communication link and transmit an indication of the restrictions over the relay link. The restrictions may differentiate data originating from the first device and the second device, restrict the first device to one or more resources, or associate logical channels at the first device with one or more transport block sizes and communication links. The second device may relay the indication of the restrictions to the first device. The first device, the second device, and the base station may communicate over the communication link according to the restrictions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may distinguish between synchronization signal blocks (SSBs) intended for different classes of UEs. For example, a base station may transmit different SSBs in a physical broadcast channel with different configurations or parameters to indicate different UE classes, where UEs may monitor for and receive SSBs for their UE class. A UE may operate according to a UE class (e.g., New Radio (NR) Light) associated with lower bandwidths and may identify SSBs associated with this UE class to connect with a base station. The UE may identify the SSBs associated with the UE class based on a subcarrier-level offset value either implicitly or explicitly indicated to the UE. Additionally, the base station may transmit fields to indicate different parameters for subsequent communications transmitted according to the UE class.

Abstract: A user equipment (UE) may receive a first group downlink control information transmission associated with a UE group, where the first group downlink control information transmission may reference a second group downlink control information transmission (e.g., according to a pre-notification indication). The UE may determine a feedback condition for the second group downlink control information transmission and monitor for the second group downlink control information transmission. Alternatively, the UE may receive a second group downlink control information transmission referencing the first group downlink control information transmission (e.g., according to a post-confirmation indication), and the UE may determine a feedback condition for the first group downlink control information transmission. Based on the feedback condition, the UE may transmit feedback information, for example, indicating that the UE did not correctly receive the indicated group downlink control information transmission.
