    摘要: Physical layer processing and procedures for device-to-device (D2D) discovery signal generation and transmission and scheduling of D2D discovery signals are described. Detection and measurement of a D2D discovery signal, D2D signal identity management, and monitoring by a wireless transmit/receive unit (WTRU) of PDCCH for D2D discovery scheduling is described, as is a WTRU that may be configured with a D2D-specific transmission/reception opportunity pattern. The discovery signal may carry a payload for explicit information about user and/or service identity, and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.

    摘要: Methods and apparatus for performing device-to-device (D2D) discovery are described. A service discovery process may include a discoverable device (e.g., a wireless transmit/receive unit (WTRU)) sending a discovery request, over a wireless connection, for a radio resource for the purpose of performing a transmission for radio frequency (RF) proximity detection for a given service. The WTRU may receive a discovery response including a configuration for RF proximity detection from a network, which configuration may be associated to the service. The configuration for RF proximity may be received by dedicated signaling, (e.g., physical downlink shared channel (PDSCH)), in particular for a discoverable WTRU. The configuration for RF proximity may be received on a broadcast channel, (e.g., a discovery shared channel (DISCH)), in particular for a monitoring WTRU, and may include one or more service identities, each associated with an RF proximity detection configuration, or a validity information and a measurement configuration.

    摘要: A method and apparatus for performing an enhanced random access procedure in a Cell_FACH state are disclosed. A wireless transmit/receive unit (WTRU) transmits a random access channel (RACH) preamble for random access. If a positive acknowledgement (ACK) is received in response to the RACH preamble, the WTRU enters a contention resolution phase and transmits a message via an enhanced dedicated channel (E-DCH). If contention resolution fails, the RACH preamble is retransmitted. A contention back-off timer may be used for retransmission. A physical random access channel (PRACH) code may be reselected. The RACH preamble may be retransmitted using a reserved PRACH resource so that E-DCH resource is allocated to the collided WTRUs. Data transmitted during the contention resolution phase may remain in a hybrid automatic repeat request (HARQ) buffer. The MAC-i/is entity may be reset. All data sent during the contention resolution phase may be stored in a temporary buffer.

    摘要: A method and apparatus for controlling uplink (UL) multiple-input multiple-output (MIMO) transmission parameters and transmissions are disclosed. A wireless transmit/receive unit (WTRU) may determine parameters, such as block sizes or transport format combinations, for transmission of a plurality of streams. The WTRU may adjust the transmission power to ensure that dedicated physical data channels are transmitted at the same level on both streams while using a WTRU calculated virtual grant on a secondary stream.
