Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station and while operating in a dual connectivity mode, an uplink grant in a first subframe of a set of subframes. The uplink grant may schedule transmission of uplink data. The UE may determine a second subframe of the set of subframes to transmit the uplink data and a third subframe of the set of subframes to monitor for feedback associated with transmission of the uplink data. The second subframe and the third subframe may be determined based on combinations of a primary cell time division duplex (TDD) uplink-downlink (UL-DL) configuration and a DL-reference UL-DL configuration. each of the combinations may have at least three uplink transmission subframes or three downlink monitoring subframes within a ten-subframe cycle. The UE may thus perform wireless communications in accordance with the transmission timelines.

Abstract: Aspects described herein relate to retransmission implementations in new radio (NR) wireless communication systems. In one aspect, a network entity may initially perform a multicast transmission and then a multicast retransmission according to a hybrid automatic repeat request (HARQ) process. In another aspect, a user equipment (UE) may initially receive a multicast transmission from a network entity and a subsequent multicast transmission according to a HARQ process. In an additional aspect, a network entity may initially perform a multicast transmission and then a subsequent unicast retransmission according to a HARQ process. In yet another aspect, a UE may initially receive a multicast transmission from a network entity and a subsequent unicast transmission according to a HARQ process.

Abstract: A base station may transmit a multicast transmission to a group of user equipments (UEs) that are each configured with a group radio network temporary identifier (G-RNTI). The UEs may be configured to receive the transmission using the same modulation and coding scheme (MCS) and transport block size (TBS) such that the group of UEs may receive the same transmission. In particular, a UE may receive one or more configurations for multicast transmissions, each configuration associated with a G-RNTI. The UE may determine a MCS table for the G-RNTI. The UE may determine a TBS for a multicast transmission based on an overhead value for the G-RNTI. The UE may receive the multicast transmission based on the MCS table and the TBS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a maximum transmission power for an uplink transmission on a first cell of a first cell group (CG) based on a direction of communications (e.g., uplink, downlink, or flexible) with a separate cell of a second CG during a same duration of the uplink transmission and within a same first frequency range, where the direction of communications is either an actual direction or an assumed direction. The UE may receive an uplink grant scheduling the uplink transmission during a symbol and within the first frequency range, determine the maximum transmission power for the UE based on the direction of communications for the separate cell during the symbol and within the first frequency range, and subsequently transmit the uplink transmission in accordance with the maximum transmission power.

Abstract: Scheduling using downlink control information (DCI) is disclosed. In a particular implementation, a method of wireless communication includes receiving, by a user equipment (UE), downlink control information (DCI) via an entity of a plurality of entities. The method also includes determining, by the UE based on the DCI, scheduling information for multiple transmissions on different entities of the plurality of entities.

Abstract: In one aspect, a method of wireless communication includes receiving, by a mobile communication device during a first cycle, a periodic grant via a first carrier of a plurality of carriers, monitoring, by the mobile communication device during a next cycle after the first cycle, for configured grants (CGs) for multiple carriers of the plurality of carriers based on the periodic grant, and receiving, by the mobile communication device during the next cycle after the first cycle, a first transmission in a first CG of the CGs via a second carrier of the plurality of carriers and a second transmission in a second CG of the CGs via a third carrier of the plurality of carriers. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for configuring for communications on noncontiguous carriers of a single cell. By combining multiple noncontiguous carriers into a single cell, broadcast overhead can be reduced and cell management (i.e., only one cell) can be simplified. For example, a network entity may transmit to a user equipment (UE) configuration information that configures the UE for communications on noncontiguous carriers of a single cell. The network entity and the UE may then communicate on the noncontiguous carriers in accordance with the configuration information.

Abstract: Some aspects of the present disclosure disclose methods and systems related to the use of a periodic reference signal to activate a secondary cell. For example, a user equipment may receive, from a base station on a primary cell, an activation command configured to activate a secondary cell. The user equipment may also receive, from the base station and on the primary cell, a signal indicating an availability of a periodic reference signal on the secondary cell, the periodic RS being for use in activating the secondary cell. The user equipment may then, in response to receiving the signal, perform a tracking function to activate the secondary cell.
