Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems operating in unlicensed or shared radio frequency spectrum band may use different modes to manage hybrid automatic repeat request (HARQ) feedback. HARQ feedback may be transmitted autonomously or, in some cases, HARQ feedback may be solicited from a user equipment (UE) for one or several HARQ processes. Solicited feedback may be referred to as polled feedback and autonomous feedback may be referred to as unpolled feedback. Polled and unpolled feedback may be transmitted using different physical channels, and may be grant-based or triggered without an express grant. Buffers for polled and unpolled feedback may be separately maintained and managed. In a multicarrier configuration, uplink control information (UCI) for one or more carriers may be transmitted on a subset of configured uplink carriers. A number of carriers used for UCI may depend on operating conditions of a UE.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may employ a multiplexing configuration based on latency and efficiency considerations. The base station may transmit a resource grant, a signal indicating the length of a downlink (DL) transmission time interval (TTI), and a signal indicating the length of a subsequent uplink (UL) TTI to one or more user equipment (UEs). The base station may dynamically select a new multiplexing configuration by, for example, setting the length of an UL TTI to zero or assigning multiple UEs resources in the same DL TTI. Latency may also be reduced by employing block feedback, such as block hybrid automatic repeat request (HARQ) feedback. A UE may determine and transmit HARQ feedback for each transport block (TB) of a set of TBs, which may be based on a time duration of a downlink TTI.

Abstract: In order to overcome problems that a UE may face in determining CORESETs and beams for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL relationships, UL resources, and/or spatial relationships are selected for a COT. A UE receives an indication of a set of CORESETs selected from a plurality of CORESETs or a set of QCL relationships selected from a plurality of QCL relationships. The UE determines the set of CORESETs from the plurality of CORESETs or the set of QCL relationships from the plurality of QCL relationships based on the indication received. A UE receives an indication of a set of UL resources or a set of spatial relations. The UE determines the set of UL resources or the set of spatial relations based on the indication received.

Abstract: The present disclosure relates generally to uplink procedures on a shared communication medium. In an aspect, an access terminal receives a downlink subframe from an access point on the shared communication medium and, in response to receiving the downlink subframe, transmits uplink control information (UCI) for the downlink subframe on a first uplink subframe of a first UCI channel of a plurality of UCI channels.

Abstract: Techniques for performing listen before talk (LBT) channel contention procedures in a shared radio frequency spectrum band are provided. The LBT techniques may include a shortened LBT procedure that may be selected if a base station has reserved a shared channel for a duration of expected user equipment (UE) uplink transmissions, and a full LBT procedure that may be selected if the base station has not reserved the channel for the duration of expected UE uplink transmissions. The shortened LBT procedure may include detecting energy levels of the channel for a relatively short time period relative to the full LBT procedure. The shortened LBT procedure may be selected if a time period between a UE receiving a grant of uplink resources and the beginning of the uplink resources is less than a threshold time value.

Abstract: Techniques for synchronization on a shared communication medium are disclosed. An access point may select, for example, a common sequence, frequency, and time for a first synchronization signal that is coordinated with one or more other access points. The access point may then transmit the first synchronization signal in accordance with the common sequence, frequency, and time. An access terminal may receive, from an access point, a first synchronization signal having a first sequence and a second synchronization signal having a second sequence. The access terminal may then determine an offset in time between the first synchronization signal and the second synchronization signal, and determine a cell identifier group associated with the access point based on the offset.

Abstract: Techniques are provided for accessing a shared radio frequency spectrum band by selecting a subset of antennas associated with a successful access procedure for accessing the shared radio frequency spectrum. In some examples, a wireless communication device, such as a network node, may perform a listen before talk (LBT) procedure for each of two or more subsets of antennas associated with the network node, and only those subsets of antennas that pass the LBT procedure are used for transmissions during the associated time period, while other antennas are idle, or used for transmissions on another radio frequency spectrum band during the associated time period. In some examples, antennas of a wireless communication device may perform an access procedure utilizing beamforming capabilities of associated antennas to determine one or more different spatial directions that may provide access to the shared radio frequency spectrum band.
