Embodiments of user equipment (UE) and methods for transmit power control for device-to-device (D2D) discovery operations and D2D communication in a cellular network are generally described herein. In some embodiments, the UE may configure a discovery signal for transmission on discovery resources from a configured resource pool for D2D discovery. The discovery signal may be transmitted at a transmit power level based on a relative location of the discovery resources with respect to uplink cellular resources in the frequency domain.

Embodiments described herein relate generally to a device that is to transmit signals using a control channel. The device may be, for example, a user equipment or low-powered radio access node. Before transmitting the signal, the transmitting device may modify symbols associated with the signal. For example, the transmitting device may generate a scrambling sequence and modulate the symbols associated with the signal with the scrambling sequence. In another example, the transmitting device may apply a shifting pattern or hopping pattern to the sequence indices associated with sequences for symbols to be included in the signal. The applied pattern may change one or more sequence indices associated with one or more symbol indices associated with the signal. Other embodiments may be described and claimed.

Embodiments of providing enhanced interference measurements for CSI feedback are generally described herein. In some embodiments, CSI-IM resources are used by UE to perform interference measurements. The serving cell determines a hopping pattern for varying a position of the determined CSI-IM resources in subframes transmitted to the served UE. The determined CSI-IM resources and the determined CSI-IM resources hopping pattern are transmitted to the served UE. The serving node transmits a zero-power (ZP) CSI-RS. The serving node receives an interference measurement from the served UE based on CSI-IM and ZP CSI-RS provided to the served UE from the serving cell. Collisions between the CSI-IM of the serving node and CSI-IM of the non-serving nodes are minimized by the determined CSI-IM resources hopping pattern.

Devices and methods of enhanced coverage (EC) paging are generally described. An evolved Node-B (eNB) may transmit multiple EC paging messages to user equipment (UE) over at least one paging cycle. Each EC paging message may contain the same paging information. The UE may combine the individual EC paging messages to achieve a predetermined link budget and subsequently may decode the EC combined paging message to determine whether the combined paging message is directed to the UE. The EC paging messages may contain information for more than one UE and a legacy P-RNTI or a specific P-RNTI for EC mode UEs. The EC paging messages may be transmitted in legacy occasions over several paging cycles or non-legacy paging occasions over one or more paging cycles. The EC paging messages may be transmitted in continuous or non-continuous subframes in a particular paging cycle.

This application discusses, among other things, methods and apparatus for providing more efficient ways to enable D2D discovery and D2D communication simultaneously. In an example, a method can include assembling device-to device (D2D) discovery data at a wireless device, assembling D2D communication data at the wireless device, assembling a D2D preamble including the discovery data and the communication data, and transmitting the D2D preamble using a wireless transmitter of the wireless device.

Embodiments of a Next Generation Node-B (gNB) and User Equipment (UE) are generally described herein. The gNB may transmit control signaling to configure transmission of position reference signals (PRSs) by a plurality of transmit-receive points (TRPs). The gNB may receive, from the UE, for each of the TRPs, a set of signal location parameters (SLPs). The gNB may perform an iterative process to estimate a position of the UE. For a current iteration, the gNB may: determine a current estimate of the position of the UE based on a current plurality of sets of SLPs; and determine a cost function for each of the current plurality of sets of SLPs. The gNB may determine, based on the cost functions, a next plurality of sets of SLPs for a next estimate of the position of the UE.

The present invention relates to a method for transmitting and receiving data in a wireless access system and a terminal therefor. The method comprises the steps of: receiving an instruction message which instructs transmission of uplink resource allocation information via a physical downlink shared channel (PDSCH) from a base station; determining whether the resource allocation information is a first downlink resource allocation information based on the instruction message, upon receiving resource allocation information set to a flag value that indicates uplink resource allocation information, from the base station via a physical downlink control channel (PDCCH); receiving uplink resource allocation information via the PDSCH according to the first downlink resource allocation information from the base station; and transmitting uplink data to the base station via a physical uplink shared channel (PUSCH) according to the uplink resource allocation information.

The present invention relates a method for a terminal to transmit acknowledgement information including determining a physical uplink control channel (PUCCH) format and resource, in which acknowledgement information is transmitted in response to a downlink transmission in a downlink sub-frame set including M (M≧1) downlink sub-frame; and transmitting the acknowledgement information using the PUCCH format and resource in one uplink sub-frame. Here, one or more serving cells including one PCell and at least one SCell are configured to the terminal. In the determining step, the acknowledgement information may be transmitted using a PUCCH format 1a/1b, when a semi-persistent scheduling release physical downlink control channel (PDCCH) does not exist in the downlink sub-frame set, and one physical downlink shared channel, which is indicated through the detection of a corresponding PDCCH having a downlink assignment index value of one, exists in the downlink sub-frame set.

In dual connectivity, a UE is served by cells are operated in different eNBs with one eNB designated as the master eNB (MeNB) and the other as a secondary eNB (SeNB). A random access procedure is described by which a UE connected to an MeNB may attempt to acquire access to an SeNB cell. The procedure may utilize the backhaul connection between the SeNB and the MeNB so that the random access response may be transmitted over an MeNB cell.

The present invention discloses a method for a terminal to transmit control information in a wireless communication system. The method includes encoding a plurality of pieces of control information and transmitting the plurality of encoded control information and data information through a data channel. During the encoding of the plurality of control information, a channel quality indicator (CQI) and a precoding matrix index (PMI) for an entire frequency band are encoded jointly or separately, and each piece of the plurality of pieces of encoded control information and the data information is mapped into a resource block of the data channel, and is then transmitted.
