Abstract: A user equipment (UE) may be configured to communicate a number of transmissions that may each have separate feedback processes. A feedback configuration for providing feedback for such separate feedback processes may be determined based on semi-static signaling and dynamic signaling. In some cases, semi-static signaling, such as radio resource control (RRC) signaling and dynamic signaling, such as downlink control information (DCI), may together provide a feedback configuration for a particular transmission. The semi-static signaling may provide a number of bits of feedback information, an interpretation of the bits of feedback information, or combinations thereof, and dynamic signaling may indicate that one or more of the bits are to have one of a number of available interpretations, may indicate that one or more additional bits are to be included with feedback, of combinations thereof. These feedback techniques may be used to provide feedback for uplink or downlink transmissions.

Abstract: Aspects of the present disclosure implement techniques to allow a base station to transmit a “short-page” message (e.g., paging indicators) to one or more UEs. The short-page message may be decoded by all UEs in the paging cycle and identifies a subset of UEs from the full set of UEs that are paged by the base station. Upon decoding the short page transmitted by the base station, the UE may respond with a “short-page response” to the base station on a transmit beam that offers best signal quality (e.g., low signal-to-noise ratio, transmit power, etc.). Thus, in some examples, the UE, in response to receiving a short paging message, may provide feedback to the base station such that the base station may select a transmit beam for transmission for a subsequent message (and other communications).

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive a downlink transmission from at least one beam of a set of beams. The set of beams may be associated with a multi-beam communication between the apparatus and a base station. The apparatus may select a beam, of the set of beams, to report beam related information associated with the at least one beam of the set of beams. The apparatus may report an indication that the beam is a selected beam.

Abstract: Methods, systems, and devices for wireless communications are described. An encoder may utilize a common mother code for encoding control information to each set of control channel resources of a control channel, control channel associated with multiple transmission configuration indication (TCI) states. For example, the common mother code may include utilizing same parameters when constructing the polar code for each set of control channel resources, where the parameters include a block length, a number of information bits, or both. Additionally, rate matching procedures for each control channel resource may differ (e.g., puncturing, shortening, or repetition). Additionally or alternatively, the mother code and rate matching may be determined based on a sum of all available coded bits in each control channel resource and the number of information bits. A decoder may then attempt soft combination of candidates from the different sets of control channel resources to obtain decoded control information.

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: Methods, systems, and devices for wireless communications are described. One method may include receiving, by a user equipment (UE) in a downlink shared data channel, a beam switch command instructing the UE to switch from a first uplink control beam to a second uplink control beam. The UE may select an uplink control beam to transmit acknowledgment feedback based on whether decoding the beam switch command is successful, and transmit, in an uplink control channel via the selected uplink control beam, the acknowledgment feedback indicating whether decoding the beam switch command was successful.

Abstract: A user equipment (UE) may measure signal characteristics of a beam reference signal and determine, based on the measured signal characteristics, a beam repetition and diversity (R/D) mode to be used in communications between the UE and a base station. In some examples, UE feedback to the base station may include an indication of the determined beam R/D mode, as well as channel quality information associated with one or more beams to which the determined beam R/D mode is to be applied and/or operating parameters (e.g., a mixed beam repetition and diversity pattern) associated with the beam R/D mode.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide a mechanism for a user equipment (UE) to identify an uplink transmit beam to be used for communicating with a base station. In some cases, the uplink transmit beam may be based on a recent uplink (or downlink) transmission or set of allocated resources. A base station may allocate communication resources for a UE. The UE may determine, based on the allocated communication resources, a default transmit beam for communicating with the base station. The UE and base station may (e.g., independently) identify a triggering condition for using the default transmit beam. The UE may transmit an uplink communication to the base station using the default transmit beam based on the triggering condition.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink message that includes a control channel monitoring periodicity and control channel offset for a radio frame. A user equipment (UE) may identify a set of slots within a radio frame to monitor for downlink control information (DCI) based on the received downlink message. The UE may identify a control channel candidate within a search space of each slot of the set of slots, and may identify the control channel candidate of a first slot based on calculations that include a current slot and a previous slot. There may be one or more slots that occur between the previous slot and the current slot. The UE may receive DCI that is user-specific based on the identified control channel candidate.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to semi-persistent configuration of reference signals (RSs), such as measurement reference signals (MRSs) for beam refinement. An example method generally includes transmitting, to a user equipment (UE), a reference symbol (RS) configuration, wherein transmitting the RS configuration is independent of activating RS training for the UE, transmitting, to the UE, a message indicating an activation of RS training subsequent to transmitting the RS configuration, transmitting RSs to the UE periodically based on the RS configuration, and receiving, from the UE, measurement reports based on the transmitted RS.
