摘要： A method and apparatus are described for a low cost machine-type-communication (LC-MTC) wireless transmit/receive unit (WTRU) to enhance coverage. An example method for physical broadcast channel (PBCH) enhancement includes receiving system information on an enhanced PBCH (ePBCH). The ePBCH is located in a set of radio frames which is a subset of available radio frames, where the subset includes fewer than all the available radio frames. The ePBCH is received in at least one radio frame of the set of radio frames. An example method for physical random access channel (PRACH) enhancement includes receiving configuration of legacy PRACH resources and enhanced PRACH (ePRACH) resources. The WTRU selects one of legacy PRACH resources or ePRACH resources based on a coverage capability. Another example method for PRACH enhancement includes receiving configuration of ePRACH resources. The ePRACH resources include multiple ePRACH resource types, each ePRACH resource type being associated with a coverage capability.

摘要： Communications may be performed in a communications system using multi-dimensional antenna configurations. A WTRU may receive communications from a base station via one or more channels. The communications may be performed using multiple component codebooks. The WTRU may send channel state information (CSI) feedback for each component codebook to the base station for consideration when performing communications with the WTRU. The WTRU may determine the CSI feedback for each component codebook based on channel measurements. The component codebooks may include a horizontal component codebook and/or a vertical component codebook. The WTRU may send the CSI feedback for each component codebook to the base station independently or in the form of a composite codebook. The WTRU may determine a composite codebook a function of the component codebooks.

摘要： Methods and systems for sending and receiving an enhanced downlink control channel are disclosed. The method may include receiving control channel information via an enhanced control channel. The method may also include using the control channel information to receive a shared channel. The method may include detecting the presence of the enhanced control channel in a given subframe. The enhanced control channel may be transmitted over multiple antenna ports. For example, code divisional multiplexing and de-multiplexing and the use of common and UE-specific reference signals may be utilized. New control channel elements may be defined, and enhanced control channel state information (CSI) feedback may be utilized. The presence or absence of legacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.

摘要： Devices and methods are disclosed for a physical sidelink control channel (PSCCH) design in new radio (NR). A wireless transmit receive unit (WTRU) for sidelink communication may receive a resource pool identity (ID). Further, the WTRU may determine whether to include information related to demodulation reference signal (DM-RS) density for a sidelink transmission in sidelink control information (SCI) based on the resource pool ID. On a condition that the information related to DM-RS density is to be included in the SCI, the WTRU may transmit the SCI including the information related to DM-RS density. Also, the SCI may be associated with a PSSCH. Accordingly, the WTRU may transmit the sidelink transmission on the PSSCH with one or more DM-RSs at a first DM-RS density based on the information related to DM-RS density.

摘要： Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

摘要： A wireless transmit receive unit (WTRU) may be configured to transmit uplink control information such as Hybrid Automatic Retransmission Request (HARQ) Acknowledgement or Negative Acknowledgement (ACK/NACK) using a sequence. The HARQ ACK/NACK may comprise one bit or two bits of information, and the WTRU may use a cyclic shift of the sequence to transmit the HARQ ACK/NACK. The WTRU may use different cyclic shifts of the sequence to transmit different HARQ ACK/NACK values and the cyclic shifts may be separated from each other in a manner to facilitate the transmissions. The WTRU may be further configured to receive, from a physical downlink control channel (PDCCH), an indication of a resource block for transmitting the HARQ ACK/NACK.
