Abstract: A wireless transmit/receive unit (WTRU) (e.g., a millimeter WTRU (mWTRU)) may receive a first control channel using a first antenna pattern. The WTRU may receive a second control channel using a second antenna pattern. The WTRU may demodulate and decode the first control channel. The WTRU may demodulate and decode the second control channel. The WTRU may determine, using at least one of: the decoded first control channel or the second control channel, beam scheduling information associated with the WTRU and whether the WTRU is scheduled for an mmW segment. The WTRU may form a receive beam using the determined beam scheduling information. The WTRU receive the second control channel using the receive beam. The WTRU determine, by demodulating and decoding the second control channel, dynamic per-TTI scheduling information related to a data channel associated with the second control channel.

Abstract: A method performed by a base station may compromise: detecting an interference pattern; determining that the interference pattern impacts one or more code blocks (CBs) within one or more code block groups (CBGs); adjusting a size of the one or more CBGs; and transmitting, to a wireless transmit/receive unit (WTRU), information associated with the adjusting of the size of the one or more CBGs. The interference pattern may be caused by a radio detection and ranging (RADAR) system. The adjusting of the size of the one or more CBGs may compromise increasing or decreasing the number of CBs within the one or more CBGs. The transmitting of the information relating to the adjusting of the size of the one or more CBGs may be performed via master information block (MIB) signaling, radio resource control (RRC) signaling, or downlink control information (DCI) signaling.

Abstract: Methods and apparatuses are described herein for robust bandwidth part (BWP) approaches to mitigate the impact of high power narrow-band interference. For example, a wireless transmit/receive unit (WTRU) may receive, from a base station (BS), configuration information indicating a plurality of initial bandwidth parts (BWPs). The plurality of initial BWPs may comprise a first initial BWP and a second initial BWP. The first initial BWP and the second initial BWP may be separated from each other in a frequency domain to avoid interference on at least one of the plurality of initial BWPs. The WTRU may send, based on failure to decode a transmission received in the first initial BWP, to the BS, an uplink transmission using the second initial BWP. The uplink transmission may include one or more preambles that are sent using a physical random access channel (PRACH).

Abstract: A wireless transmit receive unit (WTRU) and methods are disclosed for mitigating radar interference with transmission and reception of RACH preambles. According to a first aspect, one or more first RACH preambles are transmitted based on a first RACH configuration. The WTRU may receive an RAR with an indication that the first RACH configuration is unavailable. The WTRU may then retrieve a second RACH configuration information. The WTRU may then transmit one or more second RACH preambles based on the second RACH configuration and then completes a random access procedure based on the second RACH configuration.

Abstract: Methods and devices are disclosed to configure a wireless transmit receive unit (WTRU) with multiple physical downlink control channel (PDCCH) control resource sets (CORESETs) including at least a first PDCCH CORESET identifying first frequency resources of a downlink (DL) bandwidth part (BWP) for detection of downlink control information (DCI) and a second PDCCH CORESET identifying second frequency resources of the DL BWP for detection of DCI. The WTRU monitors one or more search spaces linked to active PDCCH CORSETs for transmissions of DCI. On determination that an interferer may impact PDCCH resources, a network sends, and a WTRU receives, signaling to suspend monitoring of search spaces linked to one of the first PDCCH CORSET or the second PDCCH CORESET for a suspend time period. Upon expiration of the suspend time period or sending/receiving unsuspend signaling, the WTRU resumes monitoring search spaces linked to a previously suspended PDCCH CORESET.

Abstract: Splitting data in a wireless communications network. Data may be split to use multiple base stations for transmission to user equipment in order to improve the bandwith if a UE is on a cell edge, or may be split by user equipment for transmission to multiple base stations in order to improve handover. Data splitting may be performed at the Packet Data Convergence Protocol layer, at the Radio Link Control layer, or at the Media Access Control layer on user equipment or on a base station. Data may instead be split in a network node, such as in a serving gateway, in order to reduce X2 interface load or delay carrier aggregation.
