Abstract: This disclosure provides systems, methods and apparatuses for wireless communication that may allow a user equipment (UE) to determine its relative position and distances to other UEs more accurately than standard vehicle-to-everything (V2X) communications allow. In some implementations, a UE (or other wireless communication device) participating in a positioning operation may transmit and receive positioning signals on an unlicensed radio band, and may transmit and receive non-positioning signals on a V2X channel (or on another suitable channel) of a radio access network (RAN). The positioning signals may include positioning reference signals (PRSs) associated with observed time difference of arrival (OTDOA) positioning operations, ranging signals associated with round-trip time (RTT) positioning operations, or other suitable signals from which the position of the UE can be determined.

Abstract: A method for wireless communications, comprising: signaling, to a user equipment (UE), an indication of one of at least two rules regarding how quasi co-location (QCL) configured for the UE should be applied for one or more DMRS ports; and sending downlink transmission to the UE with the one or more DMRS ports; receiving signaling from a base station and processing signals received on one or more DMRS ports based on the indicated rule. Said method improves communications between access points and stations in a wireless network.

Abstract: Methods and apparatuses for wireless communications are described. The aspects relate to a frame structure for new radio shared spectrum. For instance, the frame structure may provide shared medium access by multiple operators in a new radio shared spectrum system. Specifically, the present aspects provide for utilizing reservation preambles associated with a distinct operator for announcing to other operators a reservation of at least one transmission opportunity of a given frame in the new radio shared spectrum.

Abstract: Techniques for spectrum sharing among operators are provided. A base station (BS) licensed to a first operator monitors, while operating on a first carrier frequency assigned to the first operator, a reservation period on a second carrier frequency assigned to a second operator that shares spectrum with the first operator. The BS determines, based on the monitoring, availability of the second carrier frequency for use by the BS during at least one subsequent data period. The BS determines whether to attempt to reserve access on the second carrier frequency for use during the at least one subsequent data period based on the determined availability.

For example, the method may include obtaining a first timing value from a serving node and a second timing value from each of one or more non-serving nodes of the UE, computing one or more timing differences between the first timing value and each of one or more second timing values, and reporting the one or more timing differences to the serving node. Additionally, the disclosure describes a method, an apparatus and a computer-readable medium for use in providing time alignment in a consolidated multi-point (CoMP) transmission network by obtaining of a CoMP transmission network timing information from a plurality of user equipments (UEs) and storing the timing information for each of the plurality of UEs for communicating with the first node.

Abstract: Suppression of serving cell transmissions directed to second-served UEs may improve channel estimation of a serving cell or a neighbor cell. This may include using scheduling information for second-served UEs to suppress serving cell signals intended for second-served UEs having overlapping MIMO transmissions. Alternatively, this scheduling information may aid in suppressing a serving cell signal for a second-served UE to improve channel estimation of a neighbor cell. Various embodiments described herein, include implementations and techniques to aid channel estimation, and signal scheduling information to a first-served UE to aid in suppression of serving cell signals for second-served UEs.

Abstract: An eNB may determine a root for a sequence to be included in a signal to a UE. The eNB may generate a generalized Chu sequence based on the root and scramble the generalized Chu sequence using a pseudorandom sequence that is common to a plurality of eNBs. The eNB may transmit the scrambled generalized Chu sequence to indicate the beginning of a downlink transmission. The UE may receive this scrambled generalized Chu sequence and determine if a beginning of a downlink transmission from a serving eNB based on the received generalized Chu sequence and an expected generalized Chu sequence.
