Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an uplink communication in an uplink frequency band. The UE may transmit, at an uplink frequency within the uplink frequency band, the uplink communication with a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to downlink (DL) transmissions using various powers and assigning frequency resources based on the powers. An example base station may transmit, to a first user equipment (UE), an indication of a first transmit (Tx) power for a first DL transmission on a first downlink (DL) resource on a carrier, the first DL resource being at a first frequency. The first DL resource may be at a first frequency. The first Tx power may have a power level configured based on a difference between the first frequency for the first DL resource and an uplink (UL) frequency region of the carrier. Then, the base station may transmit the first DL transmission using the first frequency and the first Tx power. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects described herein relate to communicating in a wireless network. A resource grant comprising an indicator of whether to transmit a demodulation reference signal (RS) for an uplink control channel or an uplink data channel can be received from a network entity. It can be determined whether to transmit the RS in at least one transmission time interval (TTI) based at least in part on the indicator.

Abstract: Certain aspects of the present disclosure generally relate to techniques for selecting a base graph to be used for wireless communications. Selection can be based on a variety of factors. Abase graph can be used to derive a low-density parity-check (LDPC) code used for encoding a retransmission of an original transmission. An exemplary method generally includes selecting, based on a modulation and coding scheme (MCS) and a resource allocation (RA) for transmitting a codeword, a base graph (BG), from which to derive a low density parity check (LDPC) code for use in encoding data bits in the codeword (e.g., encoding data bits of a bitstream such that some redundant bits are included in the codeword), encoding the data bits to generate the codeword using the LDPC code derived from the selected BG, and transmitting the codeword using the MCS via resources of the RA.

Abstract: A method and apparatus for adapting uplink transmissions during wireless communications are described. The method and apparatus include transmitting, by a user equipment (UE) operating in a Ultra-Reliable Low-Latency Communications (URLLC) mode, a first transmission to a network entity in a first frequency region, the first frequency region corresponding to a reserved frequency division multiplexing (FDM) region of an uplink channel. The method and apparatus include receiving an downlink grant from the network entity in response to transmitting the first transmission, the downlink grant indicating at least a second frequency region for uplink transmissions different from the first frequency region. The method and apparatus include adapting the first frequency region to the second frequency region for transmitting one or both of a retransmission or a subsequent transmission based on the downlink grant.

Abstract: Various aspects described herein relate to managing ultra low latency (ULL) communications over a plurality of component carriers (CC). A configuration for aggregating a set of CCs can be received, wherein the set of CCs includes at least a primary cell and a secondary cell. Based on the received configuration, at least the primary cell can be communicated with for legacy communications, wherein the legacy communications are based on a first transmission time interval (TTI) having a first duration. Based on the received configuration, the primary cell and the secondary cell can be communicated with for ULL communications, wherein the ULL communications are based on a second TTI having a second duration that is less than the first duration.

Abstract: Various aspects relate to determining whether one or more subframes are multicast-broadcast single-frequency network (MBSFN) subframes. A user equipment (UE) can receive, from a base station, a system information broadcast signal that includes an indication of one or more subframes as MBSFN subframes, and a subsequent system information broadcast signal that indicates at least scheduling information for a multicast control channel (MCCH) in at least a portion of the one or more subframes. The UE can determine, based at least in part on the indication or on the subsequent system information broadcast signal, a numerology for a physical multicast channel (PMCH) corresponding to the MCCH in at least the portion of the one or more subframes, and can process at least the portion of the one or more subframes based at least in part on the scheduling information or the numerology for the PMCH.
