Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for downlink control information (DCI) communication and processing. One example method generally includes determining a limit, between a transmission time of a control channel carrying a DCI of a plurality of DCI and a time of an event enabled by the DCI, of a quantity of the plurality of DCI in a frame, generating a frame comprising the plurality of DCI in accordance with the determined limit, and transmitting the frame to a user-equipment (UE).

Abstract: Method and apparatus for control signaling for SIC operation in 2-codeword operating mode. The apparatus transmits, to a network entity, a SIC capability indication comprising an indication that the UE supports a SIC operation for 2-CW allocation and an order of processing a first codeword and a second codeword. The apparatus monitors for an ACK to enable the SIC operation between the UE and the network entity. The apparatus receives downlink communication based on the SIC operation in response to receiving the ACK to enable the SIC operation. The apparatus may process the first codeword, within the downlink communication, transmitted based on a first MCS. The apparatus may cancel interference from the downlink communication based on the first codeword to obtain the second codeword, within the downlink communication, transmitted based on a second MCS.

Abstract: Apparatus, methods, and computer program products for DL power allocation in inter-band CA with carriers with no SSB transmissions are provided. An example method may include receiving, from a second network node, SSB transmit power information for at least one carrier of a set of carriers, where the set of carriers may be associated with inter-band carrier aggregation, and where the SSB transmit power information may be indicative of an SSB transmit power or an SSB transmit power offset. The example method may further include determining a set of CSI-RS EPREs based on the SSB transmit power information for the at least one carrier, where the set of CSI-RS EPREs corresponds to a CSI-RS transmission in a first carrier of the set of carriers, where the first carrier is configured without SSB transmission.

Abstract: An apparatus may be configured to receive a polar-encoded transmission comprising at least one intermediate node associated with a first configuration of frozen leaf nodes and information leaf nodes. The apparatus may further be configured to apply an FHT to a first set of values associated with a first intermediate node of the at least one intermediate node to generate a second set of values associated with the first intermediate node. The apparatus may also be configured to select, based on the second set of values, one or more paths associated with the first intermediate node for a SSCL decoding. The apparatus may further be configured to calculate a path metric for each of the selected one or more paths associated with the first intermediate node.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for mitigating interference caused by legacy reference signals from neighbor cells (e.g., LTE cell-specific reference signals) to non-legacy downlink transmissions in a serving cell (e.g., NR/5G PDSCH transmissions).

Abstract: The disclosure relates in some aspects to information encoding. Information encoding may involve puncturing bits of a codeword or repeating bits of a codeword. The disclosure relates in some aspects to selecting a puncturing or repetition pattern. In some aspects, a puncture pattern for data encoding is selected based on a criterion that the output and the repetition input of an XOR are not erased. In some aspects, a repetition pattern for data encoding is selected based on a criterion that repetition not be applied for the output and the repetition input of an XOR.

Abstract: Aspects described herein relate to decoding downlink control information (DCI) based on multiple DCI sizes. A first hypothesis of multiple hypotheses for decoding a communication received in a control channel search space, wherein the multiple hypotheses are based on different corresponding DCI sizes can be determined. The communication received in the control channel search space can be decoded based on the first hypothesis. For each of the multiple hypotheses and based on the different corresponding DCI sizes, information bits can be extracted from the communication as decoded. For each extracting of the information bits, cyclic redundancy check (CRC) can be performed based on one of the different corresponding DCI sizes to determine whether extracting of the information bits yields DCI.

Abstract: Certain aspects of the present disclosure generally relate to techniques for combining a plurality of decision metrics of a scrambled payload in a 5G wireless communications system. For example, in some cases, combining decision metrics of a scrambled payload may generally involve receiving a first payload at a receiver that was scrambled both before and after encoding, generating a second payload at the receiver with selectively set payload mask bits, and using the selectively-set payload mask bits in the second payload to descramble the first payload.
