Abstract: Bursty interference or puncturing may be identified, either by a user equipment (UE) or by a base station. In response, a protection scheme may be applied to protect communications from the bursty interference or puncturing. The protection scheme may include using both time and frequency interleaving of code blocks in the communications. The protection scheme may also include modifying the modulation and coding scheme (MCS), coding rate, precoding matrix index (PMI), or rank indicator (RI) used in the communications. The protection scheme may also include using a universal low-density parity check (LDPC) code in the transmission of the communications.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. Various aspects relate to initial physical random access channel (PRACH) power control using multiple PRACH signals, and more particularly to supporting one or more initialization and power control operations between a user equipment (UE) and a network entity prior to an association process. The initial PRACH power control may include the UE transmitting, to the network entity, a first set of PRACH signals at different respective power levels. The network entity may transmit a response message indicating a single set of PRACH signals detected by the network entity, and the UE may detect whether a first PRACH signal, of the first set of PRACH signals, is included in the single set of PRACH signals to select a power level associated with the first PRACH signal for transmitting association messages.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may filter data tones (e.g., in edge subbands of an allocated frequency band) to achieve time domain windowing or shaping. Data tones of edge subbands of a configured frequency band may be filtered to shape a waveform such that it does not extend beyond symbol boundaries (e.g., does not result in emission leakage). In some examples, the transmitter may provide an indication of subband frequency domain shaping filters used to the receiver, to support demodulation on the receiver side. In some examples, the transmitter may indicate a demodulation reference signal (DMRS) comb structure (e.g., of the edge subbands) to the receiver, and the receiver may determine or estimate the filters of the subband frequency domain shaping based on the comb structure or the indication of the filters.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for a user equipment (UE) to share unused antennas dedicated or configured for a one radio access technology (RAT) for communications with a network entity of another RAT. The UE may communicate, via a first set of antennas using a first RAT. The UE may also communicate, via a second set of antennas, using a second RAT. To share the one or more antennas dedicated or configured for the second RAT, the UE may transmit, to the network entity of the first RAT, an indication of a capability to switch the second set of antennas from the second RAT to the first RAT. The UE may communicate with the network entity of the first RAT via the first set of antennas and via the second set of antennas.

Abstract: Methods, systems, and devices for wireless communication are described for dynamic frozen bits of polar codes for early termination and performance improvement. A wireless device may receive a signal comprising a codeword encoded using a polar code. The wireless device may perform decoding of the codeword including at least: parity check of a first subset of decoding paths for making a decision on early termination of decoding of the codeword based on dynamic frozen bits, and generating path metrics for a second subset of the decoding paths that each pass the parity check based on the dynamic frozen bits, and performing error detection on a bit sequence corresponding to one of the second subset of the decoding paths based at part on error detection bits and the generated path metrics. The wireless device may process the information bits based on a result of the decoding.

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 communications are described. The described techniques generally provide for spatially coupled multiple-in multiple-out (MIMO) signaling for a single codeword across multiple layers. A transmitting device may transmit, via multiple time-frequency resources using multiple spatial layers, a set of code blocks associated with a codeword. At a first time-frequency resource, each code block of a first subset of the set of code blocks may be mapped to a respective transmission layer, and at a second time-frequency resource, each code block of a second subset of the set of code blocks may be mapped to a respective transmission layer, where the second set of code blocks is staggered from the first set of code blocks. By staggering code blocks across multiple time-frequency resources, a receiving wireless device may cancel out interference of one or more previously decoded code blocks.
