Abstract: Various aspects of the present disclosure generally relate to wireless communication. A traffic window may be scheduled for a user equipment (UE) base on semi-persistent scheduling (SPS). In various situations, all or a portion of a first communication to be transmitted or received can be transmitted or received during an SPS grant in the traffic window. If useful, additionally, a remainder of the first communication not transmitted or received during the SPS grant may be transmitted in an on-demand grant appended to the SPS grant. The on-demand grant can be in a same subframe as the SPS grant. When the BS appends the on-demand grant to the SPS grant, the BS may transmit, and the UE may receive, an indicator indicating that the on-demand grant has been appended to the SPS grant. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to distributed joint access of an unlicensed sidelink channel. Each sidelink device may perform independent and asynchronous listen before talk (LBT) of the unlicensed sidelink channel with a respective back-off time. The first sidelink device to complete back-off may transmit a joint access synchronization (JAS) signal indicating a duration of time that the unlicensed sidelink channel may be accessed by sidelink devices. Synchronized access sharing of the unlicensed sidelink channel across different active sidelinks may then be achieved through distributed handshake signaling.

Abstract: Methods, systems, and devices for wireless communications are described techniques for configuring channel state information (CSI) process for a coordinated set of transmission reception points. The techniques for configuring channel state information (CSI) process for a coordinated set of transmission reception points may include receiving a sounding reference signal (SRS) and identifying, based at least in part on the SRS, a first CoMP set of TRPs. The techniques for configuring channel state information (CSI) process for a coordinated set of transmission reception points may also include transmitting a CSI-RS to a UE and receiving CSI from the UE. The techniques for configuring channel state information (CSI) process for a coordinated set of transmission reception points may further include identifying, based at least in part on the CSI, a second CoMP set of TRPs.

Abstract: An aspect of the present disclosure includes methods, systems, and computer-readable media for establishing, at a first UE, a network connection with a first BS of a first communication network, transmitting a scheduling request for communication resources in a second communication network by tunneling to a second BS of the second communication network through the first BS of the first communication network, receiving from the first BS via the network connection, in response to the scheduling request, information for configuring the first UE for communicating with a second UE, configuring the first UE using the received information, and transmitting, directly, a message to the second UE using the communication resources in the second communication network.

Abstract: A method for reducing the peak-to-average ratio in an OFDM communication signal is provided. The method includes defining a constellation having a plurality of symbols, defining a symbol duration for the OFDM communication signal, and defining a plurality of time instants in the symbol duration. A plurality of tones are allocated to a particular communication device, and a discrete signal is constructed in the time domain by mapping symbols from the constellation to the time instants. A continuous signal is generated by applying an interpolation function to the discrete signal such that the continuous signal only includes sinusoids having frequencies which are equal to the allocated tones.

Abstract: Various aspects described herein relate to techniques for resource configuration for random access in a wireless communication system (e.g., a cellular vehicle-to-everything (CV2X) communication system). In an aspect, the method includes identifying a set of one or more random access channel (RACH) resources and configuration, sending a first RACH message including the set, and receiving a second RACH message including a resource selected from the set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a client device may receive a discovery signal from a host device; determine whether to use a receive timing from the host device, an internal timing of the client device, or a combination of the receive timing and the internal timing to configure a reference timing; configure the reference timing, for transmission of a response to the discovery signal, using the receive timing from the host device, the internal timing of the client device, or the combination of the receive timing and the internal timing based at least in part on the determination of whether to use the receive timing, the internal timing, or the combination of the receive timing and the internal timing; and transmit the response to the host device using the configured reference timing. Numerous other aspects are provided.

Abstract: Various aspects of the disclosure relate to communicating random access information and uplink control information. In some aspects, a user equipment (UE) or other suitable apparatus transmits physical uplink control channel (PUCCH) information concurrently with random access channel (RACH) information transmitted by another UE or other apparatus. For example, the RACH access information and the PUCCH information may be frequency division multiplexed orthogonal tones. The disclosure relates in some aspects to using downlink-uplink (DL-UL) channel reciprocity to determine symbol and/or tone locations. For example, a base station or other suitable apparatus may initially sweep across different directions in different time slots to transmit signals during a synchronization sub-frame. A UE or other suitable apparatus can then find an appropriate RACH symbol from its best synchronization beam index and transmit PUCCH information in those symbols.

Abstract: The present disclosure relates to an efficient demodulation reference signal (DMRS) design to facilitate a user equipment (UE) in performing blind detection of a DMRS sequence to determine if a transmission includes data for the UE. Specifically, features of the present disclosure implement techniques that use DMRS design to facilitate blind detection of a DMRS sequence in order for the UE to determine whether a packet for the UE was transmitted during a particular SPS slot. By utilizing the techniques described herein, the base station may forego using PDCCH to provide new allocation information each time that a packet misses the assigned SPS slot.
