Abstract: Aspects presented herein may enable reduced capability UEs to support certain type of services with strict delay but limited throughput, while less parallel hardware or computational resources may be used by the reduced capability UEs. In one aspect, a UE reports, to a base station, a UE capability based on a HARQ process unit (e.g., the UE may indicate to the base station the number of available or maximum HARQ process unit (s) at the UE, etc. ). Then the UE receives downlink communication from the base station. Then the UE processes the downlink communication from the base station and providing HARQ feedback based on the reported UE capability (e.g., based on the number of available HARQ process unit (s) at the UE).

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may monitor a physical downlink control channel (PDCCH) monitoring occasion defined by an active search space (SS) set. The UE may receive, during the PDCCH monitoring occasion, a downlink control information (DCI). In response, the UE may activate at least one deactivated SS set based on the DCI and a mapping that associates an SS set to a DCI type, DCI format, transmission direction, or specific combinations thereof. In another aspect, a UE may monitor a subset less than all of PDCCH monitoring occasions defined by an active SS set. The UE may receive, during a PDCCH monitoring occasion, a DCI. In response, the UE may monitor a larger number of PDCCH monitoring occasions defined by the active SS set.

Abstract: A configuration that enables a UE to process a PDSCH DMRS bundle having a higher density of DMRS symbols at a beginning of the PDSCH DMRS bundle. The apparatus receives a PDSCH and DMRS in each slot of a plurality of slots, the DMRS being bundled across the plurality of slots, a first subset of slots of the plurality of slots each having a higher DMRS symbol density of DMRS than a second subset of slots of the plurality of slots, the second subset of slots being subsequent to the first subset of slots. The apparatus decodes each received PDSCH based on at least a subset of the received DMRS.

Abstract: Aspects of the present disclosure provide techniques configuring half duplex UEs (HD-UEs) to implement supplementary downlink (SDL) in band combination that may be in same or different frequency range designations (e.g., FR1 or FR2). Particularly, in order to compensate for the loss of downlink coverage and improve load balancing, aspects of the present disclosure configure the UE to perform random-access channel (RACH), a procedure that is a shared channel used by wireless terminals to access the mobile network, on the anchor carrier in time division duplex (TDD) band and after initial access, the UE may be configured to switch to SDL to receive subsequent downlink signals.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a downlink control information (DCI) message including an indication to enable discontinuous monitoring of a physical downlink control channel (PDCCH). The UE may enable the discontinuous monitoring of the PDCCH based on the received DCI message, and disable monitoring of the PDCCH during a temporal period in which at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled. The UE may thereby experience power saving by disabling monitoring of the PDCCH while still performing other wireless operations during the temporal period. The UE may, as a result, also include features for improvements to wireless communications and, in some examples, may promote high reliability and low latency wireless communications, among other benefits.

Abstract: Certain aspects of the present disclosure provide techniques for identifying measurement occasions (MOs) to monitor and refrain from monitoring for a repetition of a downlink channel. An example method generally includes determining that, within a monitoring occasion (MO) duration associated with decoding a number of physical downlink control channel (PDCCH) repetitions, the UE should refrain from monitoring at least one MO associated with a first control resource set (CORESET), wherein the MO duration comprises multiple MOs in which the UE is to monitor for repeated PDCCH candidates; refraining from monitoring a first subset of MOs in the MO duration, based on the determination; and monitoring a second subset of MOs within the MO duration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate using demodulation reference signal enhancements for control channel repetitions. The UE and the base station may identify a configuration to use to receive or transmit a set of repetitions of control information on a downlink control channel, each repetition of the set of repetitions including one or more symbol periods for an instance of the repeated control information. The base station may transmit, and the UE may receive, a first set of demodulation reference signals in accordance with a first set of parameter values, a second set of demodulation reference signals in accordance with a second set of parameter values, and instances of the control information during the set of repetitions. The UE may decode the control information based on the received signals and configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that a distance between an end of a first downlink control information (DCI) and a corresponding first physical downlink shared channel (PDSCH) and a distance between an end of a second DCI and a corresponding second PDSCH satisfy a minimum distance threshold for a user equipment (UE). The ends of the DCIs are to be received at the same symbol. The base station may transmit the first DCI, the first PDSCH, the second DCI, and the second PDSCH based at least in part on determining that the distances satisfy the minimum distance threshold. In some aspects, the UE may decode the first and second DCIs in an order that depends on DCI properties. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive a downlink control message from a base station scheduling multiple downlink messages and indicating a first offset for communicating a first feedback message of multiple feedback messages including feedback information for the multiple downlink messages. The UE may additionally receive, from the base station, a second offset for communicating the remaining feedback messages of the multiple feedback messages after communicating the first feedback message. The UE may transmit the first feedback message a quantity of resources equal to the first offset after receiving a first downlink message. The UE may then transmit the remaining feedback messages a quantity of resources equal to the second offset after transmitting the first feedback message. Each of the feedback messages may include feedback information for one downlink message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal mapping each of a plurality of receive port identifiers of the UE to at least one repetition of a multi-repetition downlink transmission, wherein different receive port identifiers are mapped to different repetitions of the multi-repetition downlink transmission. The UE may transmit, based at least in part on the mapping, one or more uplink reference signals using transmission ports corresponding to each receive port identifier that is mapped to at least one repetition of the multi-repetition downlink transmission. The UE may receive the multi-repetition downlink transmission according to the mapping and based at least in part on the one or more uplink reference signals.
