Abstract: Methods related to wireless communication systems and transmission and/or reception of synchronization signal block (SSB) transmissions are provided. In some scenarios, communications may occur in one or more full-duplex slots. For example, a wireless communication device receives a synchronization signal block (SSB) transmission schedule. The SSB transmission schedule at least partially overlapping with an uplink (UL) frequency portion of a full-duplex slot. The wireless communication device receives one or more SSBs, where the one or more SSBs are received in at least a slot different than the full-duplex slot or in a DL frequency portion of the full-duplex slot. Other features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an energy per resource element (EPRE) value for a slot based at least in part on whether the slot is associated with a half-duplex configuration or a full-duplex configuration, wherein the EPRE value is a first value when the slot is associated with the half-duplex configuration and a second value when the slot is associated with the full-duplex configuration; and perform a communication in the slot in accordance with the EPRE value. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for randomized frequency locations for uplink grants. The uplink grants may be “Type-1” uplink grants. The uplink grants may be used to schedule resources for ultra-reliable low-latency communications (URLLC) in new radio (NR) or 5G access. Aspects provide a method for wireless communication by a base station (BS). The BS transmits one or more uplink grants configuring a set of user equipments (UEs) with a plurality of transmission opportunities (TOs) available for uplink transmission by the set of UEs and a plurality of frequency locations associated with each TO. The BS configures the set of UEs for randomly determining one of the plurality of associated frequency locations for each of the configured TOs, for uplink transmission. The BS receives uplink transmissions from at least two of the set of UEs in at least one of the configured TOs at different frequency locations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a timing advance (TA) command that includes a timing value for calculating a timing offset to be applied to adjust a timing of an uplink transmission; determine a numerology to be used to calculate the timing offset from the timing value; and calculate the timing offset using the timing value and the numerology, wherein the timing value corresponds to different timing offsets for different numerologies. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for physical downlink control channel (PDCCH) with repetitions, including techniques for signaling the number of PDCCH repetitions, the hybrid automatic repeat request (HARD) timeline processing with PDCCH repetitions, and the demodulation reference signal (DMRS) structure for the repeated PDCCH. A method for wireless communications, by a user equipment (UE), includes determining a number of repetitions of a PDCCH. Each of the PDCCH repetitions has a same downlink control information (DCI) payload, a same aggregation level, and/or a grant for a same data channel allocation. The method includes monitoring for the PDCCH based on the determined number of repetitions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a first sub-slot periodicity for downlink semi-persistent scheduling (SPS). The UE may receive a plurality of transmissions according to the first sub-slot periodicity in a first slot, wherein the first sub-slot periodicity enables receiving the plurality of transmissions within a single slot. The UE may transmit hybrid automatic repeat request acknowledgement (HARQ-ACK) information in a second slot, wherein the second slot includes a plurality of physical uplink control channels (PUCCHs) with a second sub-slot periodicity, and wherein the HARQ-ACK information is associated with the plurality of transmissions. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure provide for enabling at least one opportunity to transmit mission critical (MiCr) data and at least one opportunity to receive MiCr data in a time division duplex (TDD) subframe during a single transmission time interval (TTI). The single TTI may be no greater than 500 microseconds. The TDD subframe may be a downlink (DL)-centric TDD subframe or an uplink (UL)-centric TDD subframe. How much of the TDD subframe is configured for the at least one opportunity to transmit the MiCr data and how much of the TDD subframe is configured for the at least one opportunity to receive the MiCr data may be adjusted based on one or more characteristics of the MiCr data. The MiCr data may have a low latency requirement, a high priority requirement, and/or a high reliability requirement. Various other aspects are provided throughout the present disclosure.

Abstract: Methods, systems, and devices for wireless communications are described. A device may aggregate multiple data bits into a group of data bits associated with an application on the device. The device may determine quality of service parameters associated with the group of data bits. The quality of service parameters may include an error rate associated with the group of data bits, a delay budget associated with the group of data bits, timing information associated with the group of data bits, or content policy information associated with the group of data bits, or a combination thereof. The device may transmit the group of data bits to another device in the wireless communication system. The group of data bits may include group header information including an indication of the quality of service parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) of a group of UEs may receive a groupcast retransmission from one or more UEs of the group. For example, a base station may transmit a groupcast transmission to the group of UEs. A first UE of the group of UEs may fail to receive the groupcast transmission and, in response, may transmit a feedback message via a sidelink feedback resource to a second UE of the group of UEs. The feedback message may include a negative acknowledgement (NACK) that indicates the failed reception of the groupcast transmission by the first UE, and the sidelink feedback resource may be indicated by the base station. The second UE may transmit a retransmission of the groupcast transmission to the first UE via a sidelink resource based on receiving the feedback message.
