Disclosed are techniques for wireless communication. In an aspect, a first UE determines a set of resources for transmission of one or more sidelink PRSs. The first UE transmits a sidelink control message to reserve the set of resources for the transmission of the one or more sidelink PRSs. In another aspect, the second UE may receive the sidelink control message, and may (e.g., transmit and/or receive/measure) the one or more PRSs in accordance with the sidelink control message. In another aspect, a third UE may receive the sidelink control message, and may determine whether a transmission by the third UE on some or all of the set of resources is permitted based on the sidelink control message.

An eNodeB (eNB), user equipment (UE) and method of providing a flexible Radio Access Technology (FRAT) are generally described. The information (resource allocation, partition information and numerology) of at least one of a plurality of RATs used by the eNB is provided to a UE. Each RAT has a flexible subcarrier spacing and symbol duration, which are integer multiples of a base subcarrier spacing and symbol duration, and is associated with at least one of different temporal and frequency resources. The symbol and/or frame structure of each RAT are independent. A Transmission Time Interval (TTI) boundary between the RATs is common, and the RATs comprise a common reference TTI duration. The information of the RATs is provided either via a different RAT than the RAT used by the UE for communication or via a dedicated carrier in the RAT used by the UE for communication.

This application relates to the wireless communications field, and in particular, to a multi-resource unit multi-RU combination indication method and apparatus. The method includes: A sending device determines a physical layer protocol data unit PPDU, where the PPDU includes a signal field, and the signal field includes a combination indication indicating whether to combine a first RU and a neighboring second RU into a multi-RU; the sending device sends the PPDU; and a receiving device determines, based on the signal field, whether the multi-RU is allocated to method station.

Some aspects provide a method for wireless communication by a user equipment (UE). The method generally includes receiving signaling of a spatial preemption indication (PI), identifying, based on the spatial PI, at least one beam that the UE is preempted from using for at least one of transmitting or receiving at least one target signal, and refraining from using the identified beam for transmitting or receiving the target signal, for at least a time period.

Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that different symbol durations coexist.

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Disclosed is a method of defining a resource block or resource element offset for mapping PTRS to a symbol, wherein the offset is determined based on an identifier of a particular user equipment, UE.

Embodiments of this application provide a method for measuring a positioning reference signal. A terminal device receives first configuration information sent by a network device, where the first configuration information includes positioning reference signal (PRS) resource information configured by the network device for the terminal device. The PRS resource information includes: a plurality of frequency layers, a plurality of transmission reception points TRPs at each frequency layer, a plurality of resource sets of each TRP, and a plurality of resources in each resource set. The terminal device measures, based on the PRS resource information and a predetermined rule, a part or all of PRSs configured by the network device for the terminal device.

A base station transmits a signal transmission to a mobile broadband (MBB) user equipment (UE) device and to a machine type communication (MTC) device that is in close proximity to the MBB UE device where the signal transmission includes control channel and a data channel. The control channel includes common location dependent control information that applies to the MTC device and the MBB UE device because they are at the same location.

A technique may include determining, by the ultra low latency user device, a decoder matrix; receiving, by the ultra low latency user device, control information indicating that a scheduled transmission of an ultra low latency data block to the ultra low latency user device is co-scheduled with a transmission of a mobile broadband data block to a mobile broadband user device via a set of shared physical resource blocks using multi-user multiple-input, multiple-output (MU-MIMO); and projecting, by the ultra low latency user device, the decoder matrix of the ultra low latency user device to be substantially orthogonal with a reference spatial subspace in which a precoder matrix for the mobile broadband user device is aligned with the reference spatial subspace, to reduce interference at the ultra low latency user device caused by the transmission of the enhanced mobile broadband data block, when receiving the ultra low latency data block.

An apparatus can include an antenna. The apparatus can include a transceiver coupled to the antenna, the transceiver configured to receive a resource assignment indicating a first set of time-frequency resources associated with a first subframe, the transceiver configured to receive a marker signal from higher layer signaling in a second subframe immediately following the first subframe, where the higher layer signaling indicates a set of orthogonal frequency multiplexed symbols including time-frequency resources used for a second latency data transmission. The apparatus can include a controller coupled to the transceiver, the controller configured to determine the first set of time-frequency resources in the first subframe from the resource assignment, the controller configured to determine a second set of time-frequency resources in the first subframe, and the controller configured to decode a first latency data transmission in the first subframe based on the determined first and second set of time-frequency resources.
