Abstract: Methods, systems, and devices for wireless communication are described. In wireless systems supporting multiple-input, multiple-output (MIMO) transmissions, devices may implement beam-forming to improve reliability of communications. A user equipment (UE) may select a set of beams, and corresponding beam indices, for communication based on reference signals received from a base station. The UE may determine values corresponding to each of the beam indices using a scalable set of tables. For example, the UE may select a subset of the tables based on the number of selected beams, and may determine the values based on these tables. In this way, the UE may efficiently store sets of tables for multiple different configurations. The UE may sum the corresponding values to obtain a combination index value, and may transmit the combination index value to the base station. The base station may determine the selected beams based on this combination index value.

Abstract: Control information may be transmitted for different TTI lengths. Different control information for the different TTIs may be transmitted using control channel resources that are established for communication of control information, such as a physical downlink control channel (PDCCH), for example. Control information for a first TTI may be located in a first set of resources, and control information for a second TTI may be located in a second set of resources. The first set of resources may be located within a first search space that may be searched by a user equipment (UE) to identify the first control information. The second set of resources may be located within a second search space that may be searched by the UE to identify the second control information.

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: Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARD) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.

Abstract: A method in accordance with aspects of the disclosure comprises receiving a plurality of downlink control information (DCI) signals, wherein each DCI signal is associated with a Demodulation Reference Signal (DMRS) Port Group (DMRS-PG) of a plurality of DMRS-PGs, and each DCI signal within the plurality of DCI signals contains a DMRS-PG Identifier (DMRS-PGID) identifying the associated DMRS-PG, performing one or more measurements associated with the each DCI signal, and generating a multi-port-group uplink control information (UCI) signal based on the one or more measurements associated with the each DCI, wherein the multi-port-group UCI signal contains an indication of whether the each DCI is successfully received. The indication can be explicitly contained in the UCI, or implicitly realized using scrambling sequences associated with DMRS-PGs to scramble the UCI.

Abstract: Methods, systems, and devices for wireless communications in a multiple bandwidth part environment are described. In response to a serving beam failure in an active bandwidth part, the UE may determine a level of support provided by the active bandwidth part for a random access procedure, and may determine a contingency (e.g. fallback) bandwidth part that supports the random access procedure. In some cases, the UE may identify the contingency bandwidth as an initial bandwidth part used by the UE for a prior random access procedure. In some cases, the base station may send to the UE, an explicit indication of the contingency bandwidth part. In some cases, the UE may identify the contingency bandwidth part based on a reference signal. Upon determining the contingency bandwidth part, the UE may perform the random access procedure using the contingency bandwidth part.

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 one or more candidate two-dimensional hypotheses for channel state information (CSI) reporting. The UE measures interference of a signal from the aggressor UE, and based on the measurement, determines one or more preferred two-dimensional hypotheses, from the candidate two-dimensional hypotheses. The UE may further determine one or more downlink transmission parameters for a downlink the UE receives, corresponding to the preferred two-dimensional hypotheses. The UE then transmits a CSI report that includes an indication of preferred two-dimensional hypotheses. The CSI report may further include the determined downlink transmission parameters. Other aspects, embodiments, and features are also claimed and described.
