Abstract: Aspects of the present disclosure relate to retransmissions of data within wireless communication networks. For a retransmission, at least a portion of the encoded bits of an original transmission may be mapped to different bit locations in one or more modulated symbols based on a non-random mapping rule. In some examples, the encoded bits of a symbol may be reversed within the symbol for a retransmission. In other examples, the first and last encoded bits within a symbol may be switched for a retransmission. Other non-random mapping rules, such as a bit location offset, may also be used to map encoded bits to different bit locations in the modulated symbol within a retransmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a multiple physical uplink shared channel (multi-PUSCH) configuration, assign a first hybrid automatic repeat request (HARQ) process identifier (HPID) and one or more redundant version identifiers (RVIDs) to two or more slots associated with a first transport block, and assign a second HPID and the one or more RVIDs to two or more slots associated with a second transport block. The first transport block and the second transport block may be part of a single configured grant period. Assigning the second HPID may include incrementing the first HPID using one or more of a physical slot count, an available slot count, or a repetition number. The UE may transmit a multi-PUSCH communication in accordance with the multi-PUSCH configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating, from multiple sets of resources associated with channel measurement, a first set of resources and a second set of resources. The UE may receive one or more first reference signals of a first set of reference signals via the first set of resources and one or more second reference signals of a second set of reference signals via the second set of resources. The UE may transmit a measurement report, including at least a first measurement associated with at least one of the one or more first reference signals and at least a second measurement associated with at least one of the one or more second reference signals, based on the control message and reception of the one or more first reference signals and the one or more second reference signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may receive second phase tracking reference signal (PTRS) configuration information for a second PTRS that is associated with a second network node. The first network node may transmit a physical downlink shared channel (PDSCH) that includes a first PTRS that is based at least in part on first PTRS configuration information, the PDSCH being based at least in part on cross-PTRS rate matching and the second PTRS configuration information. Numerous other aspects are described.

Abstract: A method for wireless communication at a transmitting wireless device and related apparatus are provided. In the method, the device determines, based on the first parameter associated with a Forward Error Correction (FEC) process and a second parameter associated with a probabilistic shaping process, the transport block (TB) size for a TB associated with a signal to be transmitted, and performs the probabilistic shaping process on a first set of data bits of the signal on the TB to obtain a second set of transmit bits. The TB cyclic redundancy check (CRC) is inserted into the TB before or after the probabilistic shaping process, and the probabilistic shaping process is applied on the TB level across multiple code blocks (CBs) associated with the TB or on the CB level individually inside each CB of the multiple CBs. The device further transmits the signal using the second set of transmit bits.

Abstract: A UE may attempt, based on a first mode, to identify a first opportunity within a preconfigured time period for a measurement associated with at least one SCC when the at least one SCC is deactivated at the UE and the measurement associated with the at least one SCC is due based on a scheduling. Based on the first mode, a radio of the UE may not be tuned to the at least one SCC when the at least one SCC is deactivated at the UE and no measurement associated with the at least one SCC is being performed at the UE. The UE may perform, if the first opportunity is identified within the preconfigured time period, the measurement associated with the at least one SCC at the identified first opportunity.

Abstract: The present disclosure provides solutions to sidelink transmission/reception problems by preparing waveforms for multiple resource blocks (RBs) in a given bandwidth. Upon determining the availability of RBs or sets of RBs the apparatuses and methods of the present disclosure allow for dynamic determination and use of available sidelink frequencies. An apparatus may comprise a memory and at least one processor coupled to the memory and configured to transmit and/or receive sidelink data in at least one contiguous set of RBs within a bandwidth part (BWP) of an unlicensed frequency band, the BWP including a plurality of RB sets, wherein the SL data is transmitted and/or received in a waveform generated for at least one of the plurality of RB sets prior to a listen-before-talk procedure indicating an availability of the at least one contiguous set of RBs for transmission.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer-readable medium for transmitting a capability signal to a network entity, wherein the capability signal indicates whether the UE is capable of supporting an uplink (UL) bandwidth that is equal to or less than a downlink (DL) bandwidth for communication over an unlicensed band; and exchanging a signal between the UE and the network entity over the unlicensed band according to the capability signal. Some alternative or additional aspects include methods, apparatuses, and computer-readable medium for receiving a signal from a network entity, wherein the signal indicates that short control signal exemption (SCSt) is applied to a synchronization signal block (SSB) transmission of one or more network entities over an unlicensed band; and skipping SSB presence detection of the one or more network entities in response to the signal.
