Abstract: A random access procedure is described for beam-based cell-less operations in fifth generation radio access technology. In one example a preamble transmission power, a preamble format, and a transmit timing are jointly determined at a user equipment (UE) for respective ones of one or more physical random access channel (PRACH) preamble transmissions. The determined preamble transmission powers, preamble formats, and transmit timing, multiple PRACH preamble transmissions are transmitted each to a target access point (AP). Based on the transmitted PRACH preamble transmissions, the UE the receives at least one random access response (RAR) message with an indication of timing advance (TA) values and beams of each target AP.

Abstract: A user equipment (UE) can process signals including a first synchronization signal (SS) and a second SS. The first SS and the second SS are beamformed with transmit beams and transmitted on subbands in a first set of symbols, for the first SS, and a second set of symbols, for the second SS. The UE can detect the first SS in the first set of symbols, and measure beam qualities of the transmit beams on the subbands in at least one of the first set of symbols or the second set of symbols. The UE can select one or more transmit beams and corresponding one or more subbands based on the measured beam qualities. The UE can detect the second SS on the selected subbands in the second set of symbol, and each of subbands in the first and second sets of symbols is associated with a transmit beam.

Abstract: Briefly, in accordance with one or more embodiments, apparatus of an evolved NodeB (eNB) comprises circuitry to configure one or more parameters for a 5G master information block (xMIB). The xMIB contains at least one of the following parameters: downlink system bandwidth, system frame number (SFN), or configuration for other physical channels, or a combination thereof. The apparatus of the eNB comprises circuitry to transmit the xMIB via a 5G physical broadcast channel (xPBCH) on a predefined resource, the xPBCH comprising a xPBCH. The xPBCH may use a DM-RS based transmission mode, and a beamformed xPBCH may be used for mid band and high band.

Abstract: Radio frame configuration circuitry for use in a device of a wireless communication system is provided. The radio frame configuration circuitry uses control circuitry to select between a plurality of different time-division duplex, TDD, configurations for a radio frame having slots with a configured duration. Transceiver circuitry performs TDD communications based on selections made by the control circuitry such that an average periodicity of switching between transmission of information and reception of information during the TDD communication is the same despite switching between different ones of the plurality of different TDD configurations. The radio frame configuration circuitry can be incorporated in a UE or an eNodeB or a Peer Radio Head. A corresponding method is provided.
