Abstract: A wireless transmit/receive unit (WTRU) is configured to receive physical uplink control channel (PUCCH) resource configuration information. The PUCCH resource configuration information comprises information indicating at least two PUCCH resources. Each of the at least two PUCCH resources comprises an indication of at least one physical resource block (PRB). Each of the at least two PUCCH resources is associated with a first type of PUCCH allocation or a second type of PUCCH allocation. The first type of PUCCH allocation is associated with frequency hopping and the second type of PUCCH allocation is not associated with frequency hopping. The WTRU is configured to determine a PUCCH resource from the at least two PUCCH resources based on an indication in a downlink control information (DCI). The WTRU is configured to send a PUCCH transmission with frequency hopping based on the determined PUCCH resource being associated with the first type of PUCCH allocation.

The method also includes determining beam-specific parameters like path loss for each beam, a configurable fractional power compensation factor for each beam, and a configurable maximum transmit power level of the each beam, wherein the fractional power compensation factor and the configurable maximum transmit power level for the each beam are determined dynamically or semi-statically based on at least deployment, WTRU mobility, or interference level. The method further includes transmitting at least one codeword to at least one receiving station using at least one of the multiple beams, which having a transmit power calculated based on the common parameters and the beam-specific parameters.

Abstract: The disclosure pertains to methods and apparatus for performing positioning of wireless transmit and/or receive units (WTRUs) in wireless communication systems. A WTRU may receive configuration information indicating a time window associated with positioning. The configuration information may indicate any of a duration and a periodicity of the time window. The WTRU may receive (1) first scheduling information indicating to transmit a first uplink transmission including a sounding reference signal (SRS) and (2) second scheduling information indicating to transmit a second uplink transmission including a positioning SRS (SRSp). The first uplink transmission may not include any SRSp. On condition that the second uplink transmission is scheduled for transmission during the time window, the WTRU may transmit the second uplink transmission during the time window and may transmit the first uplink transmission only when the first uplink transmission is scheduled for transmission outside of the time window.

Abstract: Methods and apparatus for changing cell range coverage are disclosed. A wireless transmit/receive unit (WTRU) may include circuitry configured to transmit subframes of radio frames using a physical uplink shared channel (PUSCH), where the subframes are divided into first and second sets. The circuitry may include a first power control loop utilized for the first set of subframes and a second power control loop utilized for the second set of subframes. The first power control loop may set transmission power levels for transmission over the PUSCH for the first set of subframes, and the second power control loop may set transmission power levels for transmission over the PUSCH for the second set of subframes. The circuitry may be configured with a first physical uplink control channel (PUCCH) for a first eNodeB and a second PUCCH for a second eNodeB to simultaneously communicate with the first and the second eNodeBs.

Abstract: A method to reserve a directional channel, such as in an unlicensed spectrum for instance, is disclosed. In an example embodiment, the method may be performed by a receiving node, such as a user equipment (UE) for instance. In such method, the receiving node may receive an enhanced directional transmit request message from a transmitting node and transmit an enhanced directional transmit confirmation message using one or more first beams, with at least one first beam being directed in a first direction towards the transmitting node. Further, the receiving node may transmit at least one additional enhanced directional transmit confirmation message using one or more second beams, with at least one second beam being directed in a second direction towards a potentially interfering node. In the method, the second direction is a different direction than the first direction.
