Abstract: Methods, systems, and devices for wireless communications are described. Described techniques provide for mitigating error in time or frequency adjustments for preambles of a random access procedure. A user equipment may use one value for the adjustment when transmitting data to a non-terrestrial network, but then transmit the preamble of a random access procedure according to a preamble-specific time or frequency adjustment based on one or more indications received from the network (e.g., rather than resetting the adjustment to “0”). By using some signaled value for the preamble-specific timing or frequency adjustment rather than resetting the adjustment to “0,” preamble reception performance may be maintained or improved with as many or fewer position measurements for the UE or non-terrestrial network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a differential UE-specific timing advance (TA) based at least in part on a difference between a first UE-specific TA associated with a current global navigation satellite system (GNSS) position fix and a second UE-specific TA associated with a previous GNSS position fix. The UE may transmit, to a non-terrestrial network (NTN) node, an uplink message at a time that is based at least in part on the differential UE-specific TA. Numerous other aspects are described.

Abstract: A UE may receive, from at least one cell via at least one bit in a MIB or a SIB, a barring indication based on a supported network of the at least one cell and a supported network of the UE. The supported network of the at least one cell may correspond to a TN or an NTN, and the supported network of the UE may correspond to a TN or an NTN. The UE may skip, based on the received barring indication, a selection of the at least one cell for communication. Accordingly, the UE may not camp on the at least one cell. The barring indication for NTN-supporting UEs and for TN-supporting UEs may be separately indicated via the MIB or the SIB.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a report of a maximum transport block size supported by the UE for if hybrid automatic repeat request (HARQ) feedback is enabled and a maximum transport block size for is HARQ is disabled. The UE may receive, based at least in part on transmitting the report, one or more transport blocks that have a transport block size that does not exceed the maximum transport block sizes supported by the UE. In some aspects, the UE may receive an indication of a length of a span for receiving a set of bits from channel encoder output for a transport block or a redundancy version of a transport block. Numerous other aspects are provided.

Abstract: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may transmit system information indicating multiple multicast-broadcast network areas, and may further provide configuration information for each multicast-broadcast network area indicating a location of multicast scheduling information (MSI). The MSI may include an indication of frequency resources on which to receive broadcast or multicast services. The MSI may indicate specific services for an multicast-broadcast network area that are provided via the different frequency resources (for example, different cells, carriers, channels, among other examples). In some examples, the base station may schedule broadcast or multicast services across frequency resources via semi-persistent scheduling. The MSI may indicate a redundancy version configuration (for example, time and frequency patterns for combined redundancy version broadcast transmissions).

Abstract: Methods, systems, and devices for wireless communications are described in which random access preambles may be designed to provide for relatively low inter-carrier interference (ICI) of adjacent available frequency resources in a non-terrestrial network (NTN). Random access preambles for NTN random access requests may be selected from a first set of random access preambles that are different from a second set of random access preambles for terrestrial random access requests. The first set of random access preambles may be a subset of the second set of random access preambles. The first set of random access preambles may be provided for contention-based random access (CBRA) and contention-free random access (CFRA) preambles may be configured by a base station from random access preambles that correspond to or are different from the second set of random access preambles.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a frequency resource for a multicast/broadcast service (MBS) for the UE to monitor for one or more group-common downlink control channels. The base station may transmit an indication, such as an explicit indication, of a monitoring condition for the group-common downlink control channels within the frequency resource. The UE may apply the monitoring condition by enabling or disabling the group-common downlink control channel monitoring within the frequency resource. The UE may monitor one or more downlink control channels for scheduling information from the base station according to the monitoring condition.
