In a fourth aspect, the TX UE determines the portion based multiple values of subchannel and length combinations, the multiple values determined by disabling one or more combinations of a total number of subchannel and length combination for contiguous allocation, or for contiguous and non-contiguous allocation.

Abstract: Methods, systems, and devices for wireless communication are described that may enable a user equipment (UE) to monitor a shared spectrum to receive control signaling and data transmissions associated with different transmission time intervals (TTIs). For example, a base station may communicate with a UE according to a first transmission mode during a first, shortened TTI. The base station may transmit a downlink control channel for a shortened TTI based on a subset of a number of blind decodes or control channel elements. Additionally, a downlink control channel for a shortened TTI may contain grants for multiple TTIs. In some cases, the base station may transmit a signaling to the UE via a reference signal, downlink control channel, or radio resource control which may indicate a change from the shortened-TTI transmission mode to a transmission mode with a TTI duration that is longer than the first, shortened TTI duration.

Abstract: Certain aspects of the present disclosure provide techniques for indicating and determining whether one or more of multiple uplink transmissions scheduled by a common downlink control information (DCI) are based on a channel occupancy time (COT) initiated by the UE, a COT initiated by the network entity, or a combination of COTs initiated by the UE and network entity. The determination may be based on a direct indication in the DCI for one or more of the multiple uplink transmissions. The determination may also be based on determining the type of COT for the remaining uplink transmissions not directly indicated by the DCI. For example, the DCI may indicate a COT type for only a first one of the multiple uplink transmissions and the UE determines a COT type for the remaining uplink transmissions based on various conditions and criteria.

Abstract: Certain aspects of the present disclosure provide techniques for determining a relay capability configuration for using a control signal to schedule a physical sidelink shared channel (PSSCH) that carries information to organize sidelink connections. The control signal allows user equipments (UEs) to organize a sidelink network absent base station configurations or vendor configurations. For example, the control signal may schedule a discovery signal (DS) associated with a sidelink synchronization signal block (S-SSB). The control signal may be referred to as DS-physical sidelink control channel (DS-PSCCH), different from a normal PSCCH. The DS-PSCCH may have distinct structure and content to allow UEs to organize sidelink networks.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically indicating or determining channel occupancy time (COT) for uplink transmissions. For example, a user equipment (UE) may determine whether a scheduled uplink transmission is based on CE-initiated COT or sharing a network initiated COT (both generally referred to as “COT types”) based on content in the scheduling downlink control information (DCI) or a rule applied for a configured uplink transmission. The present disclosure provides techniques for determining the COT types by using corresponding fields in the DCI when applicable, or when the corresponding fields are absent, by introducing rules configuring the uplink transmission.
