Abstract: Certain aspects of the present disclosure provide techniques for rate-matching data on a per transmission reception point (TRP) basis for single downlink control information (DCI) multi-TRP transmissions. Transmitters operating according to the present disclosure use a per TRP rate matching technique in which the rate-matching order is to first rate-match across spatial layers transmitted by a TRP, then across frequency, then across time, and then to another TRP, where remaining data is rate-matched across the spatial layers of that other TRP, then across frequency, and then across time. The described per TRP rate-matching technique causes code blocks of a transport block to be transmitted by one TRP, instead of each code block being transmitted by a group of TRPs.

Abstract: Methods, systems, devices, and apparatuses for wireless communication are disclosed. In one aspect, a base station multiplexes services on shared channel resources with preemption. The base station may send one or more control messages with multi-carrier preemption information to user equipment (UE) devices which may be affected by the preemption. The preemption information may relate to a primary component carrier and one or more secondary component carriers designated for the UEs. In some aspects, the control message may comprise an indication of the availability of preemption information for each carrier in a plurality of carriers and may also include variable-size preemption information which is identifiable to the plurality carriers based on the subset of carriers for which preemption information is indicated as available. UEs may adjust the manner in which they send or receive a data transmission based on the preemption information. Additional aspects, embodiments, and features are described and claimed.

Abstract: Certain aspects of the present disclosure provide techniques for slot aggregation in new radio (NR) systems. A method of wireless communication by a user equipment (UE) includes receiving radio resource control (RRC) signaling providing a semi-static configuration for transmission and/or reception of a repeated transport block (TB) and/or a different TB in each of a plurality of aggregated slots. The UE transmits or receives the TBs in the plurality of aggregated slots based on the semi-static configuration. Another method is provided in which the UE transmits and/or receives a demodulation reference signal (DMRS) in each of a plurality of aggregated slots, each DMRS associated with a repeated TB or a different TB in the slot. The UE determines, based on received signaling, whether the DMRS use a same precoder or a different precoder and modulates and/or demodulates the TBs in the plurality of aggregated slots based on the determination.

Abstract: Aspects of the present disclosure describe an indication channel for wireless communications that indicates whether an ultra-reliable low-latency communication (URLLC) transmission is present in an enhanced mobile broad band (eMBB) slot. A user equipment (UE) may receive an indication channel identifying one or more resources defined by time domain parts and frequency domain parts that have been punctured by an Ultra-Reliable Low latency Communication (URLLC) transmission. The number of frequency domain parts may be greater than or equal to two. The UE may determine a number of resource block groups (RBGs) in an active band width part (BWP) of the UE. The UE may map the RBGs in the BWP among each of a number of sub-bands equal to the number of frequency domain parts based on a pre-defined rule.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may transmit, using a plurality of codewords, a plurality of code block groups, wherein the plurality of codewords includes a first codeword associated with a first set of code block groups, of the plurality of code block groups, and a second codeword associated with a second set of code block groups of the plurality of code block groups. The transmitter device may retransmit, after a failure associated with at least one code block group of the first set of code block groups, the at least one code block group using the second codeword. In some aspects, the transmitter may retransmit the at least one code block group using the first codeword and transmit a new transport block using the second codeword. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to share a shared spectrum with one or more other systems (e.g., other operator networks utilizing the same radio access technology, and/or other networks utilizing different radio access technologies). Coexistence between the different systems on the shared spectrum may be provided by utilizing a technology-neutral signature waveform such as a signature sequence. A device or system may monitor a shared spectrum channel for the signature waveform, and when detected, may determine whether the shared spectrum is available for that system, or busy as occupied by another system. When the shared spectrum channel is idle, the device or system may reserve the channel by transmitting the signature waveform. Other aspects, embodiments, and features are also claimed and described.

Abstract: In order to improve the selection of search space candidates for a downlink control channel, an apparatus determines a set of decoding candidates of a lower aggregation level for a downlink control channel based on a random selection from a plurality of potential decoding candidates, wherein the plurality of potential decoding candidates are defined from a second set of decoding candidates of a higher aggregation level. The apparatus then attempts to decode the downlink control channel based on determined sets of decoding candidates of different aggregation levels. The downlink control channel may comprise a PDCCH.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may perform a Listen-Before-Talk (LBT) procedure to obtain access to a wireless communication channel. The base station may then determine a pattern of synchronization signal block (SSB) transmissions based on an outcome of the LBT procedure and transmit the pattern of SSB transmissions after obtaining access to the wireless communication channel. The outcome of the LBT procedure may include obtaining access to the wireless communication channel after a missed opportunity for at least one SSB transmission in a discovery reference signal (DRS) measurement timing configuration (DMTC) window. A user equipment (UE) may determine system timing based on a received SSB transmission.
