Abstract: Methods, systems, and devices for wireless communications are described that provide for allocation of control channel candidates for multiple component carriers (CCs) in carrier aggregation (CA) communications. A CA limit may correspond to a total number of configurable control channel candidates across multiple CCs. The control channel candidates may include blind decoding (BD) candidates or control channel element (CCE) candidates for channel estimation. A per-CC limit of control channel candidates may correspond to a number of configurable control channel candidates for each CC. An applied set of control channel candidates may be determined by allocating control channel candidates across the multiple CCs based on the CA limit and the per-CC limit. Such techniques may be used in cases where the CCs have a same numerology or mixed numerology, and may also be used for cross-carrier scheduling.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling, such as a control message or radio resource control (RRC) signaling, from a base station indicating a time interval over which to determine available power headroom relative to a transmission power threshold. The UE may calculate the available power headroom relative to the transmission power threshold as a function of UE transmission power during the time interval. The UE may transmit a power headroom report in an uplink transmission to the base station, the power headroom report indicating the calculated available power headroom. The base station may schedule one or more uplink messages at the UE according to the available power headroom.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) configured to receive a downlink in a network configured for full duplex communication. The UE receives from the network an indication of a maximum rank of an uplink from an interfering, aggressor UE. The UE measures interference of a signal from the aggressor UE, and based on the measurement, determines one or more rank values for the aggressor UE, less than or equal to the maximum rank. The UE may further determine one or more channel parameters for downlink transmissions the UE receives, corresponding to the determined rank values. The UE then transmits a channel state information (CSI) report that includes an indication of at least one of the one or more rank values for the aggressor UE. The CSI report may further include the determined channel parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure propose techniques for transmission time interval (TTI) bundling for physical downlink shared channel (PDSCH) in long term evolution (LTE). According to certain aspects a method is provided for wireless communications. The method may be performed, for example, by a user equipment (UE). The method generally includes identifying a transmit time interval (TTI) bundle comprising a subset of subframes from a set of subframes for transmitting data on a physical downlink shared channel (PDSCH) and receiving the data on the PDSCH in the subset of subframes.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) or a base station may select a sequence from a set of sequences for conveying a payload including a set of bits. A length of the selected sequence may be based on a number of time periods for conveying the payload and a number of frequency tones for conveying the payload. The communication device may apply an interleaving function to the selected sequence to generate an interleaved sequence, and transmit the payload including the set of bits using the interleaved sequence. Likewise, the communication device may receive the payload including the set of bits using an interleaved sequence, and apply an interleaving function to de-interleave the interleaved sequence to generate a selected sequence. The communication device may thereby decode the payload based on the selected sequence.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a collision between a first uplink transmission and a second uplink transmission, wherein the first uplink transmission is a high priority uplink transmission and the second uplink transmission is a low priority uplink transmission; and cancel the second uplink transmission during a defined time period, wherein the defined time period has an end point based at least in part on a processing time and an offset, and a start point based at least in part on a triggering event for the first uplink transmission or a UE capability. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for scheduling and triggering aperiodic channel state information (A-CSI) reporting on a physical uplink control channel (PUCCH) using a downlink grant. An example method generally includes receiving, from a network entity, a downlink grant including a trigger to transmit an aperiodic channel state information (A-CSI) report on a physical uplink control channel (PUCCH), generating the A-CSI report, and transmitting the A-CSI report on the PUCCH using timing and resources indicated in the downlink grant.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may monitor a downlink transmission for control information during a set of physical downlink control channel (PDCCH) monitoring occasions. The UE may determine a first configuration for the set of PDCCH monitoring occasions during a slot of the downlink transmission and a threshold number of PDCCH candidates and/or a threshold number of non-overlapping CCEs within the slot. In some cases, the UE may also determine a threshold number of PDCCH candidates and/or non-overlapping control channel elements (CCEs) within a single PDCCH monitoring occasion. The threshold number of PDCCH candidates and non-overlapping CCEs may be fixed, based on the number of PDCCH monitoring occasions during the slot, based on a processing capability of the UE, or a combination thereof. The UE may decode control information contained in one or more of the PDCCH monitoring occasions.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may determine to change a first slot format used when operating in a half-duplex mode based on a traffic pattern or a channel quality, or both, and may transmit a request to change the slot format to a base station. The request may include information relating to a slot format based on the traffic pattern or the channel quality, or both, such as an explicit indication of a slot format or a request for a different resource distribution between uplink symbols, downlink symbols, or flexible symbols, or any combination thereof. The base station may receive the request to change the slot format and may transmit an indication of a second slot format to the UE based on the request. The base station and the UE may communicate using the second slot format.
