Abstract: An apparatus may use inactive uplink portions of a downlink CC to transmit SRS to an eNB. At times there may be a collision between the SRS transmission and uplink transmissions or downlink transmissions on another CC. The apparatus receives a carrier aggregation configuration for a first downlink CC and a second CC, determines to transmit an uplink transmission on the second CC or to receive a downlink transmission on the second CC, determines that the SRS would at least partially collide with the uplink transmission or the downlink transmission, and determines to adjust at least one of the uplink transmission, the SRS transmission, or reception of the downlink transmission based on the determination of the collision and an interruption time to transmit the SRS in the uplink portion of the first CC.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A first message can be transmitted, in an inactive or idle state, a on a physical random access channel, where the first message includes a random access preamble. A second message can be received on a downlink channel in response to the first message, where the second message includes a temporary cell radio network temporary identifier and an uplink grant for the user equipment. A request can be transmitted on an uplink channel based on the uplink grant. A common search space of a downlink control channel can be monitored, such as for an acknowledgement message or a negative acknowledgement message corresponding to the request and identifiable based on the temporary cell radio network temporary identifier.

Abstract: An example data structure for managing user equipment communications in a wireless communications system is presented, as well as methods and apparatuses configured to implement the data structure. For instance, the data structure may include a downlink subframe comprising two slots and including one or more quick downlink channels having a single-slot transmission time interval. In addition, the example data structure may include one or more resource element blocks each comprising one or more resource elements into which a frequency bandwidth is divided within one or both of the two slots, wherein each of the one or more resource element blocks comprises a control channel region or a data channel region. Furthermore, the example data structure may include one or more resource grants, located within one or more control channel regions, for one or more user equipment served by the one or more quick downlink channels.

Abstract: Techniques are described for wireless communication. One method for wireless communication at a base station includes contending for access to a shared channel of a shared radio frequency spectrum band, and multiplexing first component carrier (CC) communication windows and second CC communication windows in the shared channel. A duration of orthogonal frequency domain multiplexed (OFDM) symbols of the first CC communication windows may be different from a duration of OFDM symbols of the second CC communication windows, and the multiplexing may occur on the shared channel upon winning contention for access to the shared channel. One method for wireless communication at a user equipment (UE) includes monitoring a shared channel of a shared radio frequency spectrum band for a first CC Listen Before Talk (LBT) frame, and receiving, in a second CC preamble, an indication of the first CC LBT frame.

Abstract: A method for channel state information (CSI) reporting by a wireless communication device is described. The method includes determining a codebook for a CSI report corresponding to four transmit antenna (4Tx) transmissions from a base station. The codebook has a dual codebook structure. The method also includes generating the CSI report using the codebook. The method further includes transmitting the CSI report to a base station.

Abstract: Aspects of the present disclosure provide techniques for design of channel raster for narrowband operation. One example method, performed by a base station, generally includes determining, based on one or more conditions, an exact frequency location of one channel of one or more channels to perform narrowband communications with a user equipment. The method also includes transmitting an indication of the one or more conditions to the user equipment. The method further includes communicating with the UE, based at least in part on the exact frequency location of the one channel.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify a payload size, associated with performing a search for a physical downlink control channel (PDCCH), wherein the payload size is identified based at least in part on an aggregation level, associated with performing the search for the PDCCH, or an offset associated with performing the search for the PDCCH; and perform the search for the PDCCH based at least in part on the payload size. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure describe activating a high speed train (HST) configuration for communicating with a cell in a HST based communications environment. A first signal including an HST activate indication to activate a HST configuration can be received from a cell. The HST configuration can be activated based at least in part on the HST activate indication. One or more subsequent signals can be communicated with the cell using the HST configuration based at least in part on the HST activate indication.

Abstract: A method of wireless communication at a serving base station identifies a potential interference condition based on an uplink/downlink configuration mismatch. The method includes signaling, to a neighbor base station, to restrict transmissions based on the identified potential interference condition. The transmissions may be restricted by beamforming the transmissions into a different direction and/or blocking transmissions on a frequency. The signaling prompts the neighbor base station to restrict downlink transmissions that will potentially interfere with uplink control channel transmissions received at the serving base station, or to restrict uplink transmissions, intended for the neighbor base station, that will potentially interfere with downlink control channel transmissions from the serving base station.

Abstract: Cell selection techniques are provided for network access to cells that may employ one or more coverage enhancement techniques. A user equipment (UE), which may be a machine type communication (MTC) device, upon initial acquisition or upon wakeup may measure a reference signal received power (RSRP), reference signal received quality (RSRQ), or both, and determine a cell selection value based at least in part on the RSRP, RSRQ, or a combination thereof. The cell selection value may be determined based on an offset, which may be selected based on a measurement accuracy capability of the UE. UE sequential access attempts, neighbor cell list information that may include coverage enhancement of neighboring cells transmissions, and cell re-selection measurement frequency adjustments are also described.
