Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit a random access message (e.g., a message 3) associated with a random access procedure. A hybrid automatic repeat request (HARQ) feedback may be disabled for the random access procedure. The UE may initiate a contention resolution window associated with the random access procedure for a first downlink data channel transmission of a set of downlink data channel transmissions associated with the random access procedure. The UE may receive, during the contention resolution window, the first downlink data channel transmission carrying a contention resolution medium access control-control element (MAC-CE). The UE may transmit acknowledgment information for the first downlink data channel transmission carrying the contention resolution MAC-CE based on an indication to enable the HARQ feedback.

Abstract: Methods, systems, and devices for wireless communications are described. A device may identify a transport block (TB) size for a TB that is scheduled across a set of component carriers (CCs) including a first CC and a second CC. The TB may include a first code block (CB) and a second CB. The device may rate match the TB with the set of CCs. Based on the rate matching, the device may identify redundancy portions of the first CB and redundancy portions of the second CB. The device may allocate a first redundancy portion of the first CB and a first redundancy portion of the second CB to the first CC, and may allocate a second redundancy portion of the first CB and a second redundancy portion of the second CB to the second CC. The device may transmit the TB over the set of CCs based on the allocating.

Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a mapping between downlink control information (DCI) codepoint values, multicast configurations, and unicast configurations. A DCI may then signal to the UE to apply one of a multicast configuration or a unicast configuration to receive a shared data channel transmission. For example, for a given DCI field of a group-common downlink control channel for multicast data, one or some DCI codepoint values may be associated with values configured for a multicast configuration, while remaining codepoints are associated with values configured for a unicast configuration. In some implementations, the UE may identify which multicast configuration or unicast configuration to apply based on the mapping, a type of data transmission scheduled by the DCI, specified values for the DCI codepoint values, whether the shared data channel transmission is a retransmission, or a combination thereof.

Abstract: In methods, systems, and devices for wireless communications, a user equipment (UE) may receive a downlink control information (DCI) block including DCI for a set of transport blocks scheduled for the UE, the DCI including a set of fields. The UE may decode the DCI block to obtain the DCI for the set of transport blocks, where at least two fields of the downlink control information are jointly decoded according to an encoding scheme, and where each possible output of the encoding scheme corresponds to a jointly valid combination of the at least two fields. The UE may receive the set of transport blocks from a base station based on the DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a reduced signaling handover condition has occurred. The UE may execute a reduced signaling handover from a source base station to a target base station based at least in part on determining that the reduced signaling handover condition has occurred. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for synchronization signal block (SSB) transmission in different frequency intervals. A method that may be performed by a user equipment (UE) includes receiving a first SSB from an entity in a non-terrestrial network (NTN) at a first time and frequency location. The method generally includes determining one or more time and frequency locations of one or more other SSBs from the entity in the NTN based on the first time and frequency location. The method generally includes monitoring for the one or more other SSBs at the determined one or more time and frequency locations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a multicast channel configuration that indicates a set of multicast channel time domain resources allocated to a multicast channel for a first multicast broadcast area. The UE may receive an indication of a first set of time domain resources, of the set of multicast channel time domain resources, that have a first reference signal pattern that differs in frequency domain density as compared to a second reference signal pattern used for at least one of a second set of time domain resources of the set of multicast channel time domain resources or a second multicast broadcast area. The UE may decode the first set of time domain resources based at least in part on the first reference signal pattern. Numerous other aspects are provided.
