Abstract: Methods, systems, and devices for wireless communications are described. A relay node may establish a control plane connection between the relay node and a base station, wherein establishing the control plane connection comprises receiving from the base station a first network identifier for the relay node. The relay node may receive, via the control plane connection, a relay configuration from the base station. The relay node may monitor grants associated with a set of one or more user equipment (UEs) based at least in part on the relay configuration, each UE comprising a network identifier that is different from the first network identifier. The relay node may relay communications between the base station and the set of one or more UEs according to the monitoring.

Abstract: Methods, systems, and devices for wireless communications are described that support feedback for multicast communications. A user equipment (UE) in a group of UEs may receive multicast information from a base station in a downlink (DL) transmission scheduled by a DL grant. The DL grant may also indicate a set of uplink resources for the group of UEs to use to transmit feedback. The UE may attempt to decode a message containing the multicast information in the DL transmission. If the UE determines the message was successfully decoded, the UE may send no feedback to the base station. If the UE determines the message was not successfully decoded, the UE may transmit a feedback message to the base station to indicate the message was unsuccessfully decoded. The base station may monitor for the feedback message and determine to retransmit the multicast information if the feedback message is received.

Abstract: Techniques are described for wireless communication. One method includes detecting a first reference signal received from a user equipment (UE) in a reference scheduled transmission burst including a plurality of contiguous transmission time intervals (TTIs) received over a shared radio frequency spectrum band; identifying a reference TTI in which the first reference signal is received; determining a contention window size usable by the UE to contend for access to the shared radio frequency spectrum band; and transmitting an indication of the determined contention window size to the UE.

Abstract: Methods, systems, and devices for wireless communication are described. One method may include receiving, at user equipment (UE), a control resource set configuration message from a base station; identifying an overlap between a first control resource set and a second control resource set of a wireless channel; identifying a priority level of the first control resource set and a priority level of the second control resource set based on the control resource set configuration message; and monitoring the first control resource set based on the identified overlap, the priority level of the first control resource set, and the priority level of the second control resource set.

Abstract: Techniques for reporting channel quality information (CQI) in a multi-carrier wireless communication system are disclosed. In one aspect, a user equipment determines one or more reporting groups, each comprising a plurality of component carriers which are configured for the user equipment. The user equipment may detect a trigger from a base station that selects a reporting group and may respond to the trigger by sending CQI for at least the activated component carriers in the selected reporting group.

Abstract: Aspects of the present disclosure relate to deriving spatial receive parameters for quasi-colocation at a user equipment (UE). An exemplary method generally includes receiving a plurality of beams from a base station in a plurality of coarse directions, determining, based on the plurality of beams, a first spatial colocation parameter, transmitting an indication of a coarse direction associated with a beam having a highest receive strength of the plurality of beams, receiving a plurality of second beams from the base station based on the indication, the plurality of second beams having a narrower beam width than the plurality of beams and covering a beam width of the beam associated with the indicated coarse direction, determining, based on the plurality of second beams, a second spatial colocation parameter, transmitting an indication of the second beam having a highest receive strength, and refining at least one of the first or second spatial colocation parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may identify multiple demodulation reference signal (DMRS) symbols corresponding to multiple DMRS ports of a multiple input multiple output configuration. The transmitting device may generate multiple phase-rotated and precoded DMRS symbols by applying an orthogonal cover code, a phase rotation scheme, and a precoding matrix to the identified DMRS symbols. The transmitting device may map the phase-rotated and precoded DMRS symbols to time-frequency resources corresponding to multiple antenna ports, and transmit a DMRS based on the mapped phase-rotated and precoded DMRS symbols. The transmitting device may transmit the DMRS using multiple antennas that correspond to the antenna ports.

Abstract: Methods, systems, and devices for wireless communications are described that provide for transmissions of multiple instances of control information, such as remaining minimum system information (RMSI), that may be used for system access by a user equipment (UE). The multiple instances of the control information may be combined at the UE to enhance the likelihood of successful decoding of the control information. A base station may transmit an indication that combining of multiple instances of control information is supported by the base station, and may transmit the multiple instances of control information via configured downlink transmission resources. A UE may receive the indication that combining of multiple control information instances is supported, may identify two or more instances within downlink transmission resources configured for control information transmissions, and may combine signals received in each of the two or more instances to generate a combined control information signal.

Abstract: Aspects of the present disclosure relate to techniques that may enhance radio link failure (RLF) procedures. In some cases, a UE may perform radio link monitoring (RLM) based on reference signals (RS) transmitted using a first set of beams, perform beam failure recovery (BFR) monitoring based on transmissions using a second set of beams, and adjust one or more radio link failure (RLF) parameters based on both the RLM monitoring and the BFR monitoring.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a limit on a number of concurrently active bandwidth parts, wherein the limit applies per component carrier used by the UE or across component carriers used by the UE. The UE may communicate using one or more bandwidth parts on one or more component carriers used by the UE based at least in part on the limit, wherein at least one bandwidth part of the one or more bandwidth parts is less than a full bandwidth that the UE is capable of using. Numerous other aspects are provided.
