Abstract: This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.

Abstract: Methods, systems, and devices for using a common physical downlink control channel (PDCCH) to indicate transmission beams to be used by a base station during a transmission opportunity or a periodicity to monitor search spaces are described. A user equipment (UE) may monitor a search space (in some cases, using a periodicity) for the common PDCCH to determine if transmission beams associated with the UE are to be used during the transmission opportunity. If so, the UE may wake-up during at least a portion of the transmission opportunity to receive additional information. If the common PDCCH indicates that no transmission beams associated with the UE are to be used during the transmission opportunity, the UE may enter or re-enter the sleep state. The UE may switch to a new periodicity for monitoring the search space based on the information transmitted within the common PDCCH.

Abstract: Methods, systems, and devices for wireless communication are described that support overlapping code block groups (CBGs) for multiple codewords. A receiving device may receive multiple codewords from a transmitting device over a set of spatial layers. The receiving device may determine an association between a set of feedback bits and code blocks (CBs) of the multiple codewords. The association may be based on a CBG configuration, which may bundle one or more sets of CBs of the one or more codewords using time boundaries (e.g., symbols) or based on a uniform or proportional CB distribution. Based on whether decoding of the codewords is successful, the receiving device may transmit the set of feedback bits. The number of feedback bits may be the same regardless of whether one or two codewords are received.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may allocate resources for communication with a user equipment (UE). The resources may include one or more subframes, and each subframe may include one or more shortened transmission time intervals (sTTIs). Each sTTI may be assigned a transmission direction according to a time division duplex (TDD) pattern. Based on traffic needs and/or interference from other UEs and/or base stations, the base station may determine to modify the TDD pattern used for communication. Accordingly, a base station may transmit an indicator in a control message or control region of a TTI or sTTI, to indicate to users that a transmission direction of an sTTI in the TDD pattern is being changed. Subsequently, a user may communicate with the base station according to the reconfigured TDD pattern.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to share a shared spectrum with one or more other systems (e.g., other operator networks utilizing the same radio access technology, and/or other networks utilizing different radio access technologies). Coexistence between the different systems on the shared spectrum may be provided by utilizing a technology-neutral signature waveform such as a signature sequence. A device or system may monitor a shared spectrum channel for the signature waveform, and when detected, may determine whether the shared spectrum is available for that system, or busy as occupied by another system. When the shared spectrum channel is idle, the device or system may reserve the channel by transmitting the signature waveform. Other aspects, embodiments, and features are also claimed and described.

Abstract: A user equipment (UE) may transmit a sounding reference signal (SRS) on a component carrier (CC) that is otherwise configured for downlink communications. Due to a carrier aggregation configuration or UE capability, the UE may need to retune certain components to transmit on the CC. If the SRS transmission, including the retuning time, collides with another transmission (e.g., in uplink or downlink) the UE may drop the SRS, drop the other transmission, or puncture the other transmission to facilitate the SRS transmission. The determination about a collision may depend on the retuning time, channel, or type of control information in the other transmission. In some cases, a UE may drop the other transmission if transmitting the SRS would prevent the UE from transmitting a demodulation reference signal, hybrid automatic repeat request (HARQ) feedback. In some cases, the determination may be based upon a prioritization and may also depend on a subsequent subframe.
