Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to a long uplink burst channel design. In certain aspects, the method includes determining, based on a hopping pattern, a first set of frequency resources available for transmitting uplink control information (UCI) within a first portion of a transmission time interval (TTI) and a second set of frequency resources available for transmitting UCI within a second portion of the TTI. The method also includes transmitting the UCI using the determined first set of frequency resources and the second set of frequency resources.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to utilize a shared spectrum between two or more network operators. Coexistence between the different network operators on the shared spectrum may be provided by reserving resources for exclusive use by each of the network operators within a period of time that is variable based on the number of network operators. Non-exclusive use of resources may further be granted to one or more network operators in accordance with network operator priorities.

Abstract: Wireless communications systems and methods related to reclaiming of resources in a shared frequency spectrum shared by multiple operators are provided. A first wireless communication device associated with a first operator of a plurality of operators identifies a transmission opportunity in a shared frequency spectrum shared by the plurality of operators, wherein the first operator has priority among the plurality of operators for accessing the shared frequency spectrum in the transmission opportunity. The first wireless communication device communicates with a second wireless communication device associated with the first operator, in the transmission opportunity without a prior reservation of the transmission opportunity.

Abstract: Methods and apparatuses for transmitting and detecting channel reservation preamble in a NR shared spectrum are described. An aspect may include determining whether a first reservation preamble of a first operator is received on a first time slot of multiple time slots of a downlink channel from a first network entity, and transmitting a second reservation preamble of the first operator on an uplink channel to the second network entity. Another aspect may include generating a first reservation preamble of a first operator based on at least one of a compressed representation in a signal space, a basis function of the signal space, or a CAZAC sequences; and transmitting, on a first timeslot of multiple time slots of a downlink channel, the first reservation preamble of the first operator to at least a UE. In another aspect, the SFN transmission of the first and second reservation preambles, and the low latency detection methods of the reservation preambles have been disclosed.

A method, a computer-readable medium, and an apparatus are provided. In an aspect, the method, computer-readable medium, or apparatus operates to identify a type of information for transmission, identify a rank associated with the type of information, and perform an SCDD precoding operation based at least in part on the identified type of information or the rank.

Abstract: Half-duplex (HD) operations enable low cost implementations of LTE terminals. Traditionally, HD operations may be linked to a particular frequency band which may not allow a mix of full-duplex (FD) and HD terminals in the same frequency band. Therefore, certain aspects of the present disclosure provide techniques for enabling coexistence, in a given frequency band, of HD and FD terminals, by introducing frequency bands designated for HD operation and overlapping existing frequency bands designated for FD operation.

Abstract: Aspects of the present disclosure provide techniques and apparatus for multiple physical resource block (PRB) operations for narrowband (NB) systems, such as NB internet-of-things (IoT). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE), which may be an NB-IoT device. The method generally includes performing a cell search based on one or more signals received in an anchor RB within a set of RBs available for narrowband communications with a base station (BS); determining a location of at least one additional RB available for the narrowband communications with the BS based on an indication received in the anchor RB; and performing narrowband communications with the BS using at least one of: the anchor RB or the at least one additional resource block.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation, which can be used for stand-alone/in-band/guard-band deployment. An example method is provided for operations which may be performed by a base station (BS). The example method generally includes generating a primary synchronization signal (PSS) utilizing a first code sequence and a cover code applied to the first code sequence over a first number of symbols within one or more subframes, generating a secondary synchronization signal (SSS) based on a second code sequence over a second number of symbols within one or more subframes, and transmitting the PSS and the SSS in the first and second subframes to a first type of a user equipment (UE) that communicates on one or more narrowband regions of wider system bandwidth.
