Abstract: The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

Abstract: Apparatuses and methods are disclosed for determining a transport block size (TBS) as a function of various parameters without cyclic dependencies between the parameters and TBS. The disclosed function can determine a TBS in a single pass, and the determined TBS allows the use of code blocks with equal code block size (CBS) in a transport block segmentation process. The determined TBS can provide byte-aligned code block lengths and require no padding bits in a transport block.

Abstract: Aspects of the present disclosure provide various hybrid automatic repeat request (HARQ) retransmission indication schemes used in a HARQ retransmission process. The HARQ retransmission indication can implicitly or explicitly indicate which part of a transport block (TB), code block group(s), or code block(s) is/are being retransmitted so that the receiver can associate the retransmitted TB, code block group(s), code block(s) with the correct prior reception, for example, for HARQ combining purposes.

Abstract: Aspects of the disclosure relate to an apparatus and method for wireless communication. The apparatus receives downlink control information (DCI) or a radio resource control (RRC) message indicating a configuration of an uplink burst region of a downlink-centric slot, the configuration allocating resources within the uplink burst region between a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH) or uplink control information (UCI). The PUSCH is multiplexed with at least one of the PUCCH or the UCI in the uplink burst region. The apparatus further generates a feedback signal (e.g., Transmission Control Protocol (TCP) acknowledgement (ACK)) corresponding to a downlink (e.g., TCP) data packet received from a scheduling entity and transmits the feedback signal to the scheduling entity via the PUSCH configured in the uplink burst region of the downlink-centric slot. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described that provide for service indication via downlink control information (DCI) in which different services have a same DCI size. Techniques provide also that a DCI format may be indicated by a masking operation on a cyclic redundancy check (CRC) of the DCI. The DCI may include an indicator field that may indicate the service of the associated operation. The indication may also be provided via different monitoring occasions of the DCI transmissions that are associated with different services. Different DCI search spaces also may be associated with different services and provide the service indication. Additionally or alternatively, different scrambling sequences used on all or a portion of control information or demodulation reference signal transmissions may be associated with different services.

Abstract: Methods, systems, and devices for wireless communications are described. An encoder of a wireless device may receive a transport block (TB) for transmission and segment the transport block into a set of multiple, smaller data segments that respectively correspond to a plurality of code blocks of the TB. The encoder may generate a code block level (CB-level) error detection code (EDC) for a subset of the data segments. The encoder may generate a transport block-level (TB-level) EDC for the TB using the data segments. Each of the code blocks (CBs) may be of the same size and may include one of the data segments. A subset of the CBs may include a data segment from the subset of the data segments and one of the CB-level EDCs. The remaining CBs that are not part of the subset may include a remaining data segments and the TB-level EDC.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a first grant repetition configuration of a plurality of grant repetition configurations for a user equipment (UE). The base station may generate a grant repetition parameter corresponding to the first grant repetition configuration. The base station may transmit the grant repetition parameter to the UE to indicate the first grant repetition configuration. The base station may transmit a repetition of grants in accordance with the first grant repetition configuration. The UE may receive the grant repetition parameter from the base station and determine a grant repetition configuration corresponding to the grant repetition parameter. The UE may monitor for a repetition of grants corresponding to the determined grant repetition configuration.

Abstract: Techniques are described for wireless communication. One method includes identifying a transmission time interval (TTI)-level control region, where the cascaded control region includes a TTI-level common control region and a TTI-level UE-specific control region, and where the TTI-level common control region has a pointer to a location of the TTI-level UE-specific control region; and demodulating at least one of the TTI-level common control region and the TTI-level UE-specific control region. Some techniques enable control information in a first region to point to a second region that includes additional control information. Some techniques enable two-stages of control. Semi-persistent scheduling/prescheduling control may be configured to cause an entity to refrain from demodulating one of the stages of control.

Abstract: Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.
