摘要： A method and apparatus for providing for full-duplex (FD) operation in time division duplex (TDD) communications are disclosed herein. A wireless transmit/receive unit (WTRU) may receive an indication of a first, UL heavy, TDD uplink (UL)/downlink (DL) configuration and an indication of a second, DL heavy, TDD UL/DL configuration. The WTRU may also receive a grant in a common DL subframe. The WTRU may apply the hybrid automatic repeat request (HARQ) process timing associated with one of the TDD UL/DL configurations for DL HARQ feedback. Also, the WTRU may monitor a set of subframes for a UL or a DL grant. Further, the WTRU may receive a grant in a subframe which may include an indication of a reference TDD UL/DL configuration. The WTRU may then apply the HARQ process timing associated with the reference TDD UL/DL configuration for DL HARQ feedback.

摘要： Presently disclosed are systems and methods for beamforming training in WLANs. In various embodiments, there are unified MIMO beamforming training procedure, which includes a training period in which an initiator transmits multiple unified training frames for performing a transmit-beamforming training of the initiator and a receive-beamforming training of one or more responders; a feedback period in which each responder replies with a beamforming-feedback response; and an acknowledgement period during which the initiator transmits respective acknowledgement frames to the one or more responders from which responses were received. Rules for restricted random access in various slots of the feedback period may be implemented, to address response contention between multiple qualifying responders.

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： Methods and apparatus are described herein for dynamic allocation of multiple channels and data streams for multi-channel transmission and multiple-input and multiple-output (MIMO). For example, a station (STA) may receive an enhanced poll (EPoll) frame that includes a time offset, a channel offset and antenna/sector settings from an access point (AP). The STA may transmit, based on the received EPoll frame, an enhanced service period request (ESPR) frame that includes a MIMO control field and a multi-channel control field. The MIMO control field may indicate whether the STA supports MIMO transmission. The multi-channel control field may indicate whether the STA supports multi-channel transmission. Upon transmitting the ESPR frame, the STA may receive an enhanced grant frame from the AP. The enhanced grant frame may include an antenna configuration and a multi-channel allocation to enable the STA to perform the MIMO transmission and the multi-channel transmission.

摘要： Techniques for sending an aggregated beacon in a cognitive wireless network are disclosed. A beacon device may segment beacon information and send beacon segments via a plurality of channels simultaneously. A certain information elements of the beacon information may be included in each beacon segment. Each beacon segment may include channel information for other beacon segments that are transmitted simultaneously. Alternatively, a discovery beacon may be transmitted in addition to a regular beacon. The discovery beacon may include information indicating an operating channel on which the regular beacon is transmitted. The discovery beacon may be transmitted using a predetermined channel bandwidth, with a smaller beacon interval than the regular beacon, or in a frequency hopping fashion. The discovery beacon may be sent on a channel selected based on a regulatory class and corresponding channel information. The discovery beacon may be transmitted on a side channel.

摘要： Device-to-device (D2D) cross link power control systems and methods may be disclosed. For example, a device such as a UE or WTRU may determine whether it may have simultaneous transmissions where at least one of the transmissions may include a cross link transmission. The device may further determine whether a total transmit power of the simultaneous transmissions may exceed a maximum transmit power of the device. If the device may have simultaneous transmissions and such transmissions may exceed the maximum transmit power, the device may reallocate power based on a priority or priority setting. The device may further determine a maximum cross link power, a maximum device power, and a cross link transmit power level such that the device may further control the power for transmissions based thereon.

摘要： A method and apparatus for uplink sounding reference signals (SRS) transmissions are disclosed. A WTRU-specific configuration of WTRU-specific SRS subframes for performing SRS transmissions is received. A trigger is received in a subframe from a base station to transmit a first SRS. A first subframe is selected after the subframe in which the trigger is received which is both a WTRU-specific subframe and at least four subframes after the subframe in which the trigger is received. A determination if a maximum power is exceeded in a symbol in the selected first subframe is made. On a condition that the maximum power is not exceeded in the symbol in the selected first subframe, the first SRS is transmitted in the selected first subframe. On a condition that the maximum power is exceeded in the symbol in the selected first subframe and transmission of at least one channel type other than SRS-type at least partially overlaps in the symbol in the selected first subframe, the first SRS is dropped from the selected first subframe and the at least one channel type other than SRS-type is transmitted. On a condition that the maximum power is exceeded in the symbol in the selected first subframe and transmission of at least one other SRS at least partially overlaps in the symbol in the selected first subframe, transmission powers of the first SRS and the at least one other SRS are scaled equally to comply with the maximum power, and the first SRS is transmitted in the selected first subframe in accordance with the scaled transmission powers, and the at least one other SRS is transmitted in accordance with the scaled transmission powers.

摘要： Methods and apparatuses are disclosed for a wireless transmit/receive unit (WTRU) to perform a multi-radio access technology (RAT) access (MRA) operation. The apparatus may include a WTRU comprising a transceiver and a processor configured to send a non-access stratum (NAS) access request message to a network node using a first radio access technology (RAT). The message may indicate that the WTRU can connect to both a network node using the first RAT and a network node using a second RAT. The transceiver may be configured to receive a NAS accept message and a message comprising configuration information for the second RAT. The transceiver and the processor may be further configured to connect to a network node using the second RAT based on the received configuration information and communicate with both the network node using the first RAT and the network node using the second RAT.

摘要： A method for use by an S-REDS may comprise quasi-omni broadcasting a multi-relay channel measurement request to one or more RDSs. The S-REDS may receive a first multi-relay channel measurement report from a first RDS of the one or more RDSs. The first multi-relay channel measurement report may contain first channel measurement information associated with a channel between the first RDS and the S-REDS. The S-REDS may further receive a second multi-relay channel measurement report from the first RDS of the one or more RDSs. The second multi-relay channel measurement report contains second channel measurement information associated with a channel between the first RDS of the one or more RDSs and a D-REDS.
