Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as, a base station and a UE may support transmitting and receiving information bits according to one or more index modulation schemes. For example, the communication device may support conveying information bits using a reference signal index modulation scheme, which uses reference signals transmissions using particular resources or reference signal sequences, or both, to convey the information bits. The communication device may improve reference signal resource usage by supporting a multi-mode reference signal index modulation scheme, which utilizes all reference signal resources to convey the information bits. By using the multi-mode reference signal index modulation scheme, the communication device may, as a result, include features for improvements to conveying information bits, among other benefits.

Abstract: Aspects relate to radio link management for a first type of link that is a high reliability, low-latency communication link such as ultra-reliable, low-latency communication (URLLC). Radio link failure (RLF) of the link may be determined in a wireless device that then transmits a link recovery request (LRR) communicating the RLF and a request for link recovery to a network in a reserved resource in an uplink channel using a second type of link that does not have as high priority (e.g., not as high reliability or as low-latency) as the first type of link, such as enhanced mobile broadband (eMBB). The wireless device receives a grant of uplink resources from the network responsive to the LRR, where the uplink resources are used by the wireless device to transmit an RLF report to the network and are also of the second type of link.

A group of user equipments (UEs) may receive an indication of a configuration of a sidelink resource pool. The sidelink resource pool may include one or more slots and one or more subchannels, and a slot of the sidelink resource pool may include a control region allocated for a sidelink control channel and a set of contiguous subslots each allocated for a sidelink data channel. A first UE may transmit sidelink control information (SCI) to a second UE in the control region of a slot to reserve one or more subslot of the same slot or any quantity of different slots for a sidelink message. The first UE may transmit the sidelink message to the second UE in the subslot.

Abstract: Certain aspects of the present disclosure provide techniques that may allow a base station and user equipment (UE) to be in agreement on spatial quasi co-location (QCL) assumptions for transmission in certain scenarios. The techniques may be used, for example, to determine QCL assumptions for downlink transmissions sent in an initial control resource set (CORESET) on an initial downlink bandwidth part (BWP) where dedicated signaling of such assumptions may be lacking. In some cases, the techniques may involve a UE determining a beam to use for monitoring for a physical downlink control channel (PDCCH) transmission on the initial CORESET in the initial downlink BWP that lacks dedicated signaling of QCL information and monitoring for the PDCCH on the initial CORESET in the initial BWP using the determined beam. Other aspects and features are also claimed and described.

In one aspect, a method for wireless communication includes: receiving, from a base station (BS), a first configuration for scheduling in a first cell, the first configuration comprising at least one of a first monitoring periodicity parameter or a first monitoring offset parameter associated with a search space in a second cell different than the first cell; receiving, from the BS, a second configuration for scheduling in the second cell, the second configuration comprising at least one of a different second monitoring periodicity parameter or a different second monitoring offset parameter associated with the search space in the second cell; and monitoring, in the search space in the second cell based on the first configuration and the second configuration, for downlink control information (DCI).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple channel state information (CSI) reports scheduled to be transmitted in a slot on respective physical uplink control channel (PUCCH) resources. For example, the multiple CSI reports may include one or more CSI reports associated with a first service type and one or more CSI reports associated with a second service type.

Accordingly, the UE may transmit, in the slot, one or more PUCCH transmissions that include the one or more selected CSI reports. Numerous other aspects are provided.

In one aspect, a UE can transmit UE capability information to indicate the ability of the UE to support complementary BWP operations, and the network can configure complementary BWP operations based on the UE capability.

Abstract: Methods, systems, and apparatuses for wireless communication are described. In some wireless systems (e.g., new radio (NR) systems), a system may employ fixed or variable length uplink burst regions (e.g., in an uplink-centric slot). The base station may semi-statically or dynamically configure a user equipment (UE) or group of UEs for uplink control channel transmissions within an uplink burst region. In semi-static configuration, the UE may determine the uplink control channel transmission based on values transmitted or indicated via higher-layer signaling or based on default values. In dynamic configuration, the UE may receive an indication of actual resources used by the base station in a physical layer message. The UE may transmit using an uplink control channel transmission based on the indication. In some cases, the base station may allocate code division multiplexing (CDM) groups based on which UEs are semi-statically configured and which are dynamically configured.
