Abstract: Methods, systems, and devices for wireless communication are described. Resources for narrowband communication in an unlicensed radio frequency spectrum band may be configured and allocated based on resource availability, regulatory constraints, and device capability or category. A narrowband wireless device, such as a machine type communication device or other relatively low complexity device, may communicate using one or more narrowband carriers, which may occupy between one tone and multiple resource blocks in an unlicensed spectrum band (e.g., any number of resources between one (1) tone and multiple resource blocks (RBs)). Different device types may thus be configured differently as they move between geographic regions. The base station may then communicate with the narrowband mobile device based on the resource allocation and the carrier configuration.

Abstract: Methods, systems, and devices for wireless communication are described that provide for a base station to use frequency hopping for cell acquisition according to a frequency hopping pattern. The frequency hopping pattern may include a set of anchor channels and a set of non-anchor channels used by a base station to communicate with wireless devices. The base station may occupy an anchor channel more often than a non-anchor channel and may transmit acquisition signals using the anchor channel. The anchor channel may also be used by the base station and a user equipment (UE) to exchange paging information, positioning information, random access resources, location of other channels, etc.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an uplink grant that conveys an indication of a multi-transmission opportunity (TxOP) grant. The UE may transmit, during a first TxOP, a first uplink transmission in one or more subframes in accordance with the multi-TxOP grant. The UE may transmit, during a second TxOP, a second uplink transmission in one or more subframes in accordance with the multi-TxOP grant.

Abstract: Techniques for wireless communication are described. One method includes assigning a downlink subframe that is a first occurring downlink subframe in a data frame; and transmitting an encoded control signal during a first transmission opportunity, the encoded control signal including a common portion for receiving devices, the common portion indicating a structure of the data frame, the encoded control signal further including a device specific portion for a specific receiving device, the device specific portion indicating uplink grants and downlink grants during the data frame for the specific receiving device, where at least the common portion of the encoded control signal is transmitted during the selected downlink subframe.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may transmit, to a secondary user equipment (UE), a first grant to conditionally transmit one or more data messages over a first set of resources upon completion of a detection procedure. The detection procedure may include monitoring a second set of resources for over-the-air (OTA) signals transmitted by a primary UE pursuant to a second grant, where the first set of resources at least partially overlaps the second set of resources. The UE may monitor for the OTA signals from the primary UE, determine that one or more conditions for transmission of the one or more data messages have been satisfied, and transmit the one or more data messages over the first set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a first user equipment (UE) receiving an indication of a set of sidelink resources and an indication of a set of uplink resources for transmitting sidelink feedback information. The first UE may receive a sidelink shared channel transmission from a second UE and upon receiving the sidelink shared transmission, generate feedback information regarding the sidelink shared channel transmission and transmit the feedback information directly to the base station using the set of uplink resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first UE may receive, from a second UE, resource reserving sidelink control information that indicates a transmit beam of the second UE and a sidelink resource of the second UE. The first UE may transmit data on the sidelink resource of the second UE using a transmit beam of the first UE that does not spatially overlap with the transmit beam of the second UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may perform a channel access procedure to gain access to a bandwidth part in a shared spectrum for sidelink communications with a second UE. The first UE may transmit a signal to the second UE using one or more sub-bands of the bandwidth part, and the signal may include one or more sidelink synchronization signal blocks (S-SSBs) multiplexed with frequency resources associated with a physical sidelink shared channel (PSSCH). The one or more S-SSBs may be transmitted using a set of symbol periods of a transmission time interval (TTI) (e.g., a slot) that are preceded by a least four initial symbol periods of the TTI. In some examples, the first UE may transmit a sidelink control information (SCI) message indicating which of the one or more sub-bands include the one or more S-SSBs.
