Abstract: Certain aspects of the present disclosure relate to techniques for determining resource elements REs used for Coordinated Multipoint (CoMP) transmission schemes. The techniques generally include determining, by a User Equipment (UE), a set of data REs used for Coordinated Multipoint (CoMP) operation. The determination is based on a CoMP scheme and data REs available to particular base stations involved in the CoMP operation. The technique further includes processing data received via the CoMP operation on the determined set of data REs.

Abstract: Configured grant (CG) channel occupancy time (COT) sharing procedure is disclosed. A user equipment (UE) sharing a COT may indicate in the uplink control indicator (UCI) the remaining COT duration, an offset indication identifying where the uplink transmission is expected to end, and a channel access priority class (CAPC) which may be used by the base station to determine which type of data may be included in downlink transmissions in the shared COT. Where the energy detection (ED) threshold has not been configured for COT sharing, the UE may reduce the information included in the UCI. The base station may alternatively configured which information for the UE to include in the UCI for potential COT sharing. The COT sharing information may further be compressed by coding such information into tables or leveraging knowledge of transmission characteristics, such as configured end points.

Abstract: Design of robust radio link monitoring framework for unlicensed spectrum is disclosed. The network may configured two different types of radio link monitoring (RLM) reference signal (RS) resources: default resources, which are transmitted throughout a connection, and additional resources, which may be transmitted only when there has been failure of transmission or reception of the default resources. Various criteria may be used by the network to trigger scheduling transmission of the additional RLM-RS. Moreover, different criteria may prompt a user equipment (UE) to begin monitoring the additional RLM-RS resources, including autonomous and network-initiated criteria.

Abstract: This disclosure provides systems, methods, and apparatuses for random access channel (RACH) occasions that overlap each other in time and frequency. In one aspect, the RACH occasions may use different preamble sequence sets. A base station may signal configuration information indicating the preamble sequence sets for the RACH occasions and information indicating a time-frequency resource allocation of the RACH occasions. A UE may perform a random access procedure in accordance with the configuration information.

Abstract: A method, computer-readable medium, and apparatus are provided. In addition, the apparatus may determine a first set of subframes in the narrowband TDD frame structure used for transmitting a downlink control channel to a UE. In one aspect, a last subframe in the first set of subframes may be subframe n. Further, the apparatus may determine a second set of subframes in the narrowband TDD frame structure used for transmitting a downlink data channel to the UE. In certain aspects, a first subframe in the second set of subframes may be delayed based on k0 number of subframes after the subframe n. In certain other aspects, a last subframe in the second set of subframes may be subframe n+k0+x. Additionally, the apparatus may signal first information associated with the k0 number of subframes to the UE in a first delay field in a DCI transmission.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a base station transmitting to a user equipment (UE) a partial bandwidth configuration for uplink transmissions, where the partial bandwidth configuration may indicate a channel interlace and a portion of a channel bandwidth, for example, for autonomous uplink (AUL) transmissions. The base station may also transmit to the UE an AUL configuration including a group identifier. The UE may determine a starting offset with respect to an AUL subframe for a partial bandwidth transmission based on the group identifier. In some cases, different UEs may be grouped into groups of UEs allocated non-overlapping resources, and UEs allocated overlapping resources may have different starting offsets to begin transmitting. According to the determined starting offset, the UE may perform the partial bandwidth transmission over the channel interlace and the portion of the channel bandwidth.
