Abstract: Methods, systems, and devices for wireless communications are described. In wireless communications, operators may coordinate resource sharing over respective carriers. A user interface may receive, by a first network entity associated with a first carrier from a second network entity associated with a second carrier, an indication of a first set of time intervals when the second carrier is available for communications from the first network entity. The first network entity may be associated with a first operator and the second network entity may be associated with a second operator. Both the first network entity and the second network entity may be coupled to a single radio unit. The first network entity may transmit based on receiving the indication, control signaling indicating a carrier aggregation mode associated with the first carrier and the second carrier for one or more user equipment.

Abstract: Methods, systems, and devices for wireless communications are described that provide for dynamic carrier sharing at a radio unit (RU) by multiple operators. Multiple operators may coordinate regarding resource separation such that wireless resources associated with the shared carrier may be split between the operators using, for example, time-division multiplexing, frequency-division multiplexing, and/or spatial-division multiplexing. Signal transmissions to and from the RU, using a carrier that supports multiple operators, may be based on a separation between certain physical layer (PHY) transmissions, where some PHY transmissions to or from the RU may be common for the multiple operators, and other PHY transmissions may use different sets of resources that are respectively associated with the different operators.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions to at least one receiver UE across transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting at least one LBT report to the network entity on a physical uplink control channel (PUCCH) resource that occurs before another PUCCH resource used for transmitting acknowledgment feedback for the PSSCH transmissions.

Abstract: Systems and method for configuring and providing discontinuous reception (DRX) operations in sidelink (SL) mode 1 and mode 2 are disclosed. A first user equipment (UE) may operate in DRX communications with a second UE over a SL while concurrently maintaining DRX communications with a base station. In some embodiments, DRX operations may include the first UE monitoring for either one or both of transmissions in a downlink from a base station and in the SL from the second UE during an active period of a DRX cycle of the DRX configuration. In embodiments, the UE may extend the active period associated with the DRX cycle when control information from either the base station or the second UE is received. Other aspects and features are also claimed and described.

Abstract: Method and apparatus to use different GI sequences for different FDM UEs. The apparatus calculates a GI of each UE from a set of UEs based at least on a delay spread associated with each UE from the set of UEs. The apparatus multiplexes data and the GI of each respective UE from the set of UEs to generate a waveform. The apparatus transmits the waveform to the set of UEs. The apparatus may receive, from each UE from the set of UEs, the delay spread associated with each UE from the set of UEs. The apparatus may multiplex the GI of each respective UE from the set of UEs prior to performing a DFT operation on the GI and the data. The apparatus may multiplex the GI of each respective UE from the set of UEs after performing an IDFT operation to generate the waveform.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may receive a downlink control information (DCI) on a physical downlink control channel (PDCCH). The DCI may include one or more of an indication of a set of transmission configuration indicator (TCI) states related to a physical downlink shared channel (PDSCH), one or more receive beams associated with the set of TCI states, or a physical downlink shared channel (PDSCH) scheme. The UE may decode the DCI and may determine a temporal period associated with the indication of the set of TCI states. The UE may receive, based on the temporal period, the PDSCH according to one or more of the set of TCI states, the one or more receive beams associated with the set of TCI states, the PDSCH scheme, or one or more default receive beams.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sidelink channel access via a floating channel occupancy. In some aspects, a cellular device may operate within a proximity of one or more wireless fidelity (Wi-Fi) devices and may conditionally support a search space associated with a floating sidelink synchronization signal block (SSB). For example, if the cellular device detects that the Wi-Fi devices are precluding the cellular device from acquiring channel access or otherwise making it relatively more difficult for the cellular device to acquire channel access, the cellular device may enable or active a use of the search space associated with the floating sidelink SSB. If enabled or activated, the cellular device may transmit a floating sidelink SSB within the search space independent of slot boundaries upon a successful listen-before-talk (LBT) procedure.
