Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine a scrambling sequence for a control channel, wherein the scrambling sequence is determined using a same identifier irrespective of whether the control channel is associated with a cell radio network temporary identifier (C-RNTI) or another type of RNTI, and wherein the scrambling sequence is determined based at least in part on an identifier associated with the wireless communication device and a value associated with an RNTI of the wireless communication device; and transmit or receive the control channel. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide low-density parity-check (LDPC) codes having pairwise orthogonality of adjacent rows, and a new decoder that exploits the pairwise row orthogonality for flexible decoder scheduling without performance loss. An apparatus includes a receiver configured to receive a codeword in accordance with a radio technology across a wireless channel via one or more antenna elements situated proximal the receiver. The apparatus includes at least one processor coupled with a memory and comprising decoder circuitry configured to decode the codeword based on a LDPC code to produce a set of information bits. The LDPC code is stored in the memory and defined by a base matrix having columns in which all adjacent rows are orthogonal in a last portion of the rows.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine indices associated with m consecutive elements. In an aspect, each of the m consecutive elements may be associated with a different index. In addition, the apparatus may bit reverse a binary sequence associated with each of the m consecutive elements. In an aspect, each of the m consecutive elements may include a different binary sequence. Further, the apparatus may determine a bit-reversed order of the indices based at least in part on the bit-reversed binary sequence associated with each of the m elements. In addition, the apparatus may write each of the m consecutive elements to a different memory bank in parallel based at least in part on the bit-reversed order of the indices.

Abstract: Aspects described herein relate to receiving, from a network node, downlink control information (DCI) including a parameter having a value indicating whether uplink control information (UCI) is to be multiplexed with an uplink control channel or an uplink shared channel, multiplexing, based on the value, UCI with one of the uplink control channel or the uplink shared channel, and transmitting one of the uplink control channel or the uplink shared channel multiplexed with the UCI. Other aspects relate to generating the DCI and demultiplexing the UCI.

Abstract: Disclosed are systems and techniques for wireless communications. For example, a first network device can determine at least one of position accuracy requirements or range accuracy requirements for other network devices to participate in a positioning session with the first network device. The first network device can transmit, to one or more second network devices, accuracy requirement information comprising at least one of the position accuracy requirements or the range accuracy requirements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a resource reservation that indicates a reservation for one or more resources; and transmit an indication that at least one resource of the one or more resources is in conflict with an additional resource reservation, the indication including one or more of an identification of the at least one resource, an identification of the resource reservation, or an identification of the second UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communication device may implement a low-density parity-check (LDPC) code to encode and/or decode bits of a signal. The LDPC code may be defined by a base graph and a lifting scheme. The base graph may include check nodes and variable nodes. The lifting scheme may define a quantity of copies of the base graph used to generate the LDPC code and respective cyclic shifts associated with connected variable nodes and check nodes. The respective cycle shifts may be defined such that one or more cycles associated with a minimum length of the LDPC code are associated with a restriction on second degree variable nodes, nodes associated with least significant bits, or a combination thereof. Additionally, or alternatively, the respective cycle shifts may be defined such that a weighted girth of the LDPC code satisfies a threshold.

Abstract: Methods, systems, and devices for wireless communications are described. An example method for wireless communication at a first user equipment (UE) may include receiving at least a first sidelink transmission from a second UE, wherein at least a second sidelink transmission from a third UE is scheduled contemporaneously with at least the first sidelink transmission from the second UE. The method may also include transmitting an indication in a transmission occasion to at least one of the second UE or the third UE based at least in part on a prioritization of information for the transmission occasion, wherein the indication indicates that at least the first sidelink transmission from the second UE is scheduled contemporaneously with at least the second sidelink transmission from at least the third UE.

Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes, a first user equipment (UE) may receive, from a second UE, a coordination message indicating a set of resources associated with sidelink communications and a preference of the second UE for one or more subsets of the set of resources. The first UE may transmit the sidelink communications using one or more resources of the set of resources based on the preference of the second UE for the one or more subsets of the set of resources. In some examples, the one or more resources may be selected from candidate resources within a resource selection window of the first UE. Additionally, or alternatively, the candidate resources may be based on the preference of the second UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive coordination information for sidelink communication in a distributed scheduling mode. The UE may select, in the distributed scheduling mode, a value for a sidelink communication parameter based at least in part on the coordination information. The UE may transmit a sidelink communication using the value of the sidelink communication parameter that is selected based at least in part on the coordination information. Numerous other aspects are described.
