摘要： Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

摘要： Apparatus, methods, and computer-readable media for facilitating a resource reservation indication for mode 2 resource allocation with power saving are disclosed herein. An example method for wireless communication at a wireless device includes mapping one or more slots of a sidelink resource reservation to physical slots based on periodic on-durations of a power saving mode for sidelink communication. The example method also includes transmitting SCI indicating the sidelink resource reservation that indicates the one or more slots. Another example method for wireless communication at a first wireless device includes receiving SCI indicating a sidelink resource reservation for a second wireless device, the SCI indicating one or more slots of the sidelink resource reservation. The example method also includes mapping the one or more slots to physical slots based on periodic on-durations of a power saving mode for sidelink communication.

摘要： Wireless communications systems and methods related to transmitting sidelink channel state information (CSI) from one user equipment (UE) to another UE using a L1 signal. A first UE requests a CSI report from a second UE. The first UE sends a reference signal which the second UE measures to determine channel characteristics. The second UE forms a CSI report which includes a rank indicator, a channel quality indicator, and potentially a precoding matrix index indicator. The second UE forms the CSI report at the PHY level. The CSI report is included in reserved field(s) of a second stage sidelink control information (SCI-2). The first UE receives and processes the CSI report at a PHY level.

摘要： Methods, systems, and devices for wireless communications are described. Techniques described herein relate to a user equipment (UE) that may include a wakeup radio in addition to a main radio to monitor for wakeup signals while the UE is in a sleep mode. The wakeup radio receiver may use less power than the main radio. In some examples, a first UE may indicate to a wireless node (e.g., a controlling sidelink UE or a network entity) that the UE is capable of sending wakeup signals to a second UE. In such examples, the wireless node may transmit a wakeup signal intended for the second UE to the first UE based on the capability report. The first UE may relay the wakeup signal to the second UE. Responsive to receiving the wakeup signal, the second UE may wake up the main radio of the second UE for communications.

摘要： 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.

摘要： A first UE may receive, from a second UE via a first sidelink, a first TB. The first TB may be associated with a first priority. The first UE may receive, from a third UE via a second sidelink, a second TB. The second TB may be associated with a second priority. The first UE may forward the first TB to a fourth UE and the second TB to a fifth UE via physical layer multiplexing over a third sidelink and a fourth sidelink, respectively, based on the first priority and the second priority. To forward the first TB to the fourth UE and the second TB to the fifth UE, the first UE may perform an AF operation or a DF operation.

摘要： A UE may multiplex first UCI of a first priority with second UCI of a second priority. The first UCI may include at least one of a first modulation order or a first number of MIMO layers, and the second UCI may include at least one of a second modulation order or a second number of MIMO layers. The first modulation order of the first UCI may be greater than or equal to the second modulation order of the second UCI, and the first number of MIMO layers of the first UCI may be greater than or equal to the second number of MIMO layers of the second UCI. The UE may transmit, to a base station, an UL transmission including the first UCI of the first priority multiplexed with the second UCI of the second priority, where the second priority corresponds to a higher priority than the first priority.

摘要： Techniques and devices for wireless communications are described. A user equipment (UE) may receive a configuration from a network entity for multiplexing a reference signal with a data signal in time and in frequency or for multiplexing the reference signal in a Doppler domain. The UE may receive an assignment of multiple time-frequency resources from the network entity for transmission of the reference signal. The UE may multiplex the reference signal across the assigned time-frequency resources in accordance with the received configuration. The UE may transmit the multiplexed reference signal to the network entity.

摘要： Some techniques and apparatuses described herein provide generation of a set of orthogonal sequences for transmission of a signal including a payload using an orthogonal base sequence in a time domain. In one example, the orthogonal base sequence in the time domain may be a pi over 2 (pi/2) binary phase shift keying (BPSK) sequence in the time domain, such as prior to transform precoding for transmission. Some techniques and apparatuses described herein provide for the set of orthogonal sequences to be generated such that the set of orthogonal sequences are orthogonal within a symbol (e.g., an orthogonal frequency division multiplexing symbol) by applying an intra-symbol orthogonal cover code (OCC). Applying the intra-symbol OCC provides intra-symbol orthogonality. Thus, a peak to average power ratio of a user equipment is reduced for uplink transmissions and intra-symbol orthogonality is preserved.
