Abstract: Wireless communications systems and methods related to communicating positioning reference signals (PRSs) for narrowband communication are provided. A first wireless communication device determines a time-frequency PRS pattern based at least in part on a narrowband communication frequency band configuration and a PRS subframe configuration mode associated with a set of subframes. The first wireless communication device communicates, with a second wireless communication device, a plurality of PRSs using the determined PRS time-frequency pattern in the set of subframes. The PRS subframe configuration mode can indicate a first configuration including a bitmap indicating a set of PRS subframes positioned within a group of contiguous subframes, a second configuration indicating a subset of the group of contiguous subframes that may carry the PRSs, or a combination thereof. The first configuration and/or the second configuration can be used to indicate the set of subframes.

Abstract: Methods, systems, and devices for wireless communications are described that support group-based acknowledgment feedback techniques. Two or more different groups of downlink transmissions may each have an associated group-based acknowledgment feedback, and a base station may transmit downlink control information to a UE that indicates one or more parameters that are used to determine which downlink transmissions are to be reported in the group-based feedback. Based on the parameters in the downlink control information, the UE may determine the feedback to be reported, and a timing for when to transmit the feedback to the base station.

Abstract: Wireless communications systems and methods related to uplink (UL) communications in a wireless network are provided. In one embodiment, a first wireless communication device receives a transmission grant indicating a transmission period. The first wireless communication device selects a starting location for transmitting a communication signal from among a plurality of starting locations within the transmission period. The first wireless communication device transmits the communication signal during the transmission period based on the selected starting location. In one embodiment, a first wireless communication device transmits, to a second wireless communication device, a transmission grant indicating a transmission period. The first wireless communication device monitors for a communication signal from the second wireless communication device in the transmission period. The first wireless communication device identifies, upon detection of the communication signal, a starting location of the communication signal from among a plurality of starting locations within the transmission period.

Abstract: There is a need to support narrowband TDD frame structure for narrowband communications. The present disclosure provides a solution by supporting one or more narrowband TDD frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a narrowband TDD frame structure for narrowband communications. The apparatus may also determine a PUSCH format of a group of PUSCH formats for allocating at least one RU to a UE for a NPUCCH. In addition, the apparatus may allocate the at least one RU to the UE using the determined PUSCH format. In one aspect, the RU may include one or more subcarriers in each of one or more slots.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support a determination of user equipment (UE) capabilities, such as a category or a coverage level for broadcast or multicast content. In some cases, a radio interface may be configured to account for an indicated capability of a target UE. For example, a base station may receive an indication of a capability of a particular targeted UE. The capability of the targeted UE may be specified by a service provider to deliver multicast or broadcast content, and subsequently associated with a radio interface between the base station and the target UE. The radio interface may then be configured based on the indicated capability of the target UE, for example, by configuring a transport block size or bandwidth. The base station may then transmit broadcast or multicast content to the UE using the configured radio interface.

Abstract: Wireless communications systems and methods related to sharing a channel occupancy time (COT) associated with a scheduled UL transmission in a frequency spectrum shared by multiple network operating entities are provided. A first wireless communication device communicates, with a second wireless communication device, a first uplink (UL) scheduling grant. The first wireless communication device communicates, with second wireless communication device, a first UL communication signal based on the first UL scheduling grant during a first COT, the first COT based on an extended clear channel assessment (eCCA) associated with the first UL communication signal. The first wireless communication device communicates, with the second wireless communication device, a downlink (DL) communication signal during the first COT based on COT sharing information associated with the first COT.

Abstract: Wireless communications systems and methods related to channel reservations and channel monitoring in a channel shared by multiple network operating entities are provided. A first wireless communication device transmits a first configuration indicating a first set of channel monitoring occasions for a channel. Each channel monitoring occasion of the first set of channel monitoring occasions is aligned to a start of a transmission slot. The first wireless communication device transmits, based on a first listen-before-talk (LBT) in the channel, a first channel reservation signal to reserve a first transmission opportunity (TXOP) in the channel, the first channel reservation signal transmitted during a first channel monitoring occasion of the first set of channel monitoring occasions that is within the first TXOP. The first wireless communication device communicates, with a second wireless communication device, a first communication signal in the channel during the first TXOP.

Abstract: There is a need to support narrowband TDD frame structure for narrowband communications. The present disclosure provides a solution by supporting one or more narrowband TDD frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a narrowband communication frame structure comprising a FDD mode or a TDD mode and a particular TDD frame structure for narrowband communications from a group of narrowband TDD frame structures. The apparatus may determine a periodicity, subframe number, and transmission sequence associated with a SSS based at least in part on the narrowband TDD frame structure. The apparatus may transmit the SSS using the narrowband TDD frame structure determined for the narrowband communications. In one aspect, the SSS may be transmitted in a same subframe within a frame and at a periodicity of 2 or more frames.
