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. In one aspect, the apparatus may receive information associated with a narrowband TDD frame structure for narrowband communications, the narrowband TDD frame structure including a set of contiguous uplink subframes. The apparatus may also determine an orthogonal sequence length associated with a reference signal (RS) based on at least one of a number of uplink subframes or a number of slots in the set of contiguous uplink subframes. In addition, the apparatus may transmit the RS using the determined orthogonal sequence length.

Abstract: Methods and apparatuses for adaptive subcarrier spacing in wireless communication networks are described. For example, the described aspects include transmitting, from the UE to a network entity, a first PRACH transmission with a first subcarrier spacing; determining, by the UE, that the first PRACH transmission to the network entity is not successful; and transmitting, from the UE, a second PRACH transmission with a second subcarrier spacing in response to determining that the first PRACH transmission is not successful, wherein the first subcarrier spacing is different from the second subcarrier spacing.

Abstract: Certain aspects of the disclosure relate to techniques and apparatus for improving random access for SRS switching in a wireless network. Prior to transmitting a SRS, a UE may interrupt communication on a first carrier to switch from the first carrier to a second carrier to transmit a PRACH. To reduce interruption to the first carrier, the UE may use the beginning symbol(s) of a UpPTS on the second carrier to transmit the PRACH. In addition, to reduce interruption to the first carrier, the UE may monitor for another PDCCH order before transmitting another PRACH. Further, aspects of the present disclosure provide techniques and apparatus for jointly triggering SRS transmissions and performing power control for SRS transmissions. A BS may trigger SRS transmissions from multiple UEs, trigger SRS transmissions from multiple carriers from the same UE at the same time and/or perform power control separately for each carrier.

Abstract: Certain aspects of the present disclosure provide techniques for determination, selection, configuration, and/or indication of resource allocation patterns for scheduling services, such as reliable low-latency services (e.g., ultra-reliable low latency communications (URLLC)) and other services in a wireless network, such as new radio (NR) (e.g., a 5G network). A method of wireless communication by a user equipment (UE) is provided. The method generally includes determining a resource allocation pattern that defines resources, from a plurality of configured resource allocation patterns, wherein at least one of the plurality of configured resource allocation patterns comprises a plurality of resource elements with at least a first resource element associated with a first resource allocation restriction and at least a second resource element associated with a second resource allocation restriction and communicating based on the determined resource allocation pattern.

Abstract: According to aspects, a BS may determine presence of a narrow GB or lack of a GB to separate a first RB used for DL transmission from the BS to a first UE and a second RB used for DL transmission from the BS to a second UE. In response to the determination, the BS may transmit, to the first UE, interference information associated with the transmission from the BS to the second UE. According to aspects, a BS may determine a presence of a narrow GB or lack of a GB to separate a first RB used for UL transmission from a first UE to the BS and a second RB used for UL transmission from a second UE to the BS. In response to the determination, the BS may transmit to the first UE, interference information associated with the UL transmission from the second UE to the BS.

Abstract: Aspects of the present disclosure relate to methods and apparatus for optimizing real time services (e.g., such as a voice over Long Term Evolution (LTE) (VoLTE)) for devices with limited communications resources, such as machine type communication (MTC) devices and enhanced MTC (eMTC) devices. In one aspect, a UE determines a first configuration of subframes within at least one radio frame available for the UE and other UEs to use for bundled communications with a BS. The UE receives an indication of one or more subframes within the at least one radio frame that are unavailable for bundled uplink transmissions, and determines a second configuration of subframes to use for bundled communications based on the indication. The UE overrides the first configuration of subframes with the second configuration of subframes, and communicates with the BS using the second configuration of subframes. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure are generally directed to monitoring different decoding candidates assuming different encoding schemes. For example, certain aspects of the present disclosure are directed to a method for wireless communication. The method generally includes determining a first encoding scheme used to encode first downlink control information (DCI) and a second encoding scheme used to encode second DCI, and monitoring one or more first decoding candidates for the first DCI based on the first encoding scheme and one or more second decoding candidate for the second DCI based on the second encoding scheme.
