Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain emission control information that indicates a first emission control configuration associated with a first operating configuration and a second emission control configuration associated with a second operating configuration. The UE may transmit, using the first emission control configuration or the second emission control configuration based at least in part on a UE operating configuration associated with the UE, a communication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a group-common physical downlink shared channel (PDSCH), where the group-common PDSCH is repeated for a number of repetitions. Accordingly, the UE may determine this number of repetitions and then monitor for the group-common PDSCH based on the number of repetitions. In some implementations, the group-common PDSCH may include a semi-static repetition scheme, where the number of repetitions is indicated via a group aggregation factor. Additionally or alternatively, the group-common PDSCH may include a dynamic repetition scheme, where the number of repetitions is indicated via a group repetition number. Additionally, the techniques described herein may enable the configuration for the repeated group-common PDSCH to include gaps between each repetition of the group-common PDSCH and for the UE to transmit acknowledgment feedback for the repetitions of the group-common PDSCH.

Abstract: Certain aspects are directed to a user equipment (UE) configured to receive reference signals from a network node via multiple resource element groups (REGs) including at least one REG carrying a downlink transmission. In some examples, the UE may be configured to receive, from the network node, communication parameters for a downlink transmission, the communication parameters indicative of a first resource element group (REG) bundle and a second REG bundle. In some examples, the UE may receive the downlink transmission via the first REG bundle. In some examples, the UE may be configured to perform channel estimation of the downlink transmission based on reference signals transmitted via the first REG bundle and the second REG bundle.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more physical downlink shared channel (PDSCH) communications scheduled by downlink control information (DCI). The UE may transmit, for the one or more PDSCH communications, hybrid automatic repeat request (HARQ) feedback using a sub-codebook of a set of sub-codebooks, wherein the sub-codebook is a single-cell scheduling sub-codebook, of the set of sub-codebooks, or a multi-cell scheduling sub-codebook, of the set of sub-codebooks, based at least in part on whether the DCI is a first format configured for scheduling on a single carrier or a second format configured for scheduling on a plurality of carriers. Numerous other aspects are described.

Abstract: A base station may transmit a broadcast/multicast service in a multicast broadcast single frequency network (MBSFN) area multicast communication. A method of wireless communication at a base station in accordance with an aspect of the present disclosure comprises determining a broadcast/multicast service to be provided to a user equipment (UE) in a multicast broadcast single frequency network (MBSFN) area, and transmitting a tracking reference signal (TRS) to the UE, the TRS indicating information associated with receiving the broadcast/multicast service by the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, where the UE may identify a closed loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission based on the multicast transmission transmitted to multiple UEs. The closed loop power control parameter may be indicated by a base station in a separate message than a downlink control information (DCI) scheduling the multicast transmission. For example, the base station may transmit the indication of the closed loop power control parameter in a group-transmit power control DCI or in a configuration for transmitting sounding reference signals. Additionally, the UE may adjust a transmit power for the acknowledgment feedback based on whether or not a DCI scheduling a retransmission is received in a time window after transmitting the acknowledgment feedback.

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 communication apparatus includes a circuitry and a transmitter. In operation, the circuitry generates a Demodulation Reference Signal (DMRS) and generates downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the transmitter transmits the DMRS and the downlink control information. The plurality of mapping patterns include a first mapping pattern and a second mapping pattern. Resource elements used for the DMRS of the second mapping pattern are same as a part of resource elements used for the DMRS of the first mapping pattern. A number of the resource elements used for the DMRS of the first mapping pattern is larger than a number of the resource elements used for the DMRS of the second mapping pattern.

A user equipment (UE) may establish a connection, with base station, over a first and second component carrier and may monitor a search space configured for scheduling multiple component carriers. In some cases, the UE may be configured to monitor a search space allocated for a virtual component carrier associated with scheduling multiple component carriers, or the UE may be configured to monitor for a subset of physical downlink control channel (PDCCH) candidates in search spaces associated with the first and second component carriers, where the subset of PDCCH candidates may be allocated for multi-component carrier scheduling. The UE may receive downlink control information (DCI) that schedules a set of data transmissions over the first and second component carriers and the UE may perform or receive the set of data transmissions over the first and second component carrier.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently allocating resources for multicast feedback from one or more user equipment (UEs) and efficiently retransmitting information in transport blocks to the one or more UEs. If a UE fails to decode one or more transport blocks of a set of transport blocks from a base station, the UE may report feedback, such as a negative acknowledgment (NACK), to the base station. The base station may receive the feedback from the UE and potentially from other UEs that failed to decode one or more transport blocks of the set of transport blocks, and the base station may multicast one or more outer-coded transport blocks to the UEs. Each of the outer-coded transport blocks may include a different combination (for example, a linear combination) of transport blocks of the set of transport blocks.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARQ) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more retransmissions of an initial group-common transmission. The UE may receive, in accordance with a first SPS configuration, a group-common transmission of a group-common downlink shared channel, the group-common transmission being associated with a first RNTI. The UE may transmit feedback information for the group-common transmission. The UE may then receive a downlink control information (DCI) message scheduling either a group-common retransmission of the group-common downlink shared channel or a unicast retransmission of the group-common downlink shared channel. The DCI may indicate that either the group-common retransmission is associated with the first RNTI or that the unicast retransmission is associated with a second RNTI that may be different from the first RNTI.

A field size of the field may be based on the sets of parameters, and a respective value for the field may indicate a respective set of parameters of the sets of parameters for one or more carriers of the set of carriers. Based on receiving a control message and decoding the associated field, the UE may communicate via at least one carrier of the set of carriers using the respective set of parameters for the at least one carrier.
