摘要： An apparatus and method are disclosed for enhancing connection mobility control for small cell networks that may include receiving location information of a wireless transmit/receive unit WTRU. In some embodiments, the method may include determining the location information of the WTRU. The method may include determining a target cell area TCA for the WTRU based on the location information of the WTRU. The TCA comprises one or more target cells. The method may further include transmitting at least one target cell to the WTRU. A method on a WTRU may include receiving a target cell area TCA from a base station. The TCA may include one or more target cells. The method may include responding to a radio link failure (RLF) or handover failure by selecting a target cell from the TCA, and transmitting a connection reestablishment request to the selected target cell. ADDITIONAL DETAILS: The serving BTS calculates a candidate target cell list (TCA, essentially the NCL or a subset thereof) based on a multitude of criteria such as street topology, history of past HO-failures or RLF or UE's speed, location, predicted trajectory or explicit trajectory communicated by the UE to the BTS and transmits it (reference sign 740) to the BTS's of the TCA, together with the UE's context, through the X2 interface (thus, preparing them for HO). The BTS's are prioritized according to the probability of HO occurrence. On HO failure (e. g., T304 timeout), the UE sends a second RACH to the next target cell candidate, which may be prepared or unprepared. If an unprepared cell receives a RACH from the UE, it sends a reset handover to the served cell (paragraph 149).

摘要： Systems, methods and instrumentalities are provided to implement a mechanism of a secondary user (SU) system coexisting with a primary user (PU) system. The SU system may gather information associated with the operation cycle(s) of the PU system of a shared channel. An operation cycle of the PU system may include a quiet phase and a pulse phase. For example the SU system may gather information associated with the operation cycle of the PU system. Such information may include pulse phase duration, pulse duty cycle, and/or allowed hopping sequences, etc. Based on information associated with the operation cycle of the PU system, the SU system may transmit or schedule transmission on the shared channel during the quiet phase of the PU operation cycle. The SU system may perform interference mitigation based on the timing of the pulse phase.

摘要： A method and apparatus for coexistence among wireless transmit/receive units (WTRUs) operating in the same spectrum are disclosed. A WTRU includes a memory, a receive unit, a transmit unit and a control unit. The memory stores coexistence gap patterns. Each of the coexistence gap patterns defines a pattern of transmission periods and silent periods for the WTRU and corresponds to a respective duty cycle. The receive unit receives from a base station information regarding a duty cycle for a wireless cell operated by the base station. The control unit selects one of the coexistence gap patterns based on the received information regarding the duty cycle for the wireless cell and controls the transmit unit to transmit information during the transmission periods and not transmit information during the silent periods of the selected one of the plurality of coexistence gap patterns.

摘要： A method and apparatuses for operation in a shared spectrum (SS) among a primary user (PU) and other users are disclosed. An access point (AP) or station (STA) may determine that a primary user is using SS frequency and only a portion of an 802.11 channel is available for AP/STA use. The AP may receive spectrum usage information of a PU from a database and transmit this information to a STA. The AP and STA may determine PU usage based on the information and change to a fractional spectrum mode. Based on PU usage, the AP and STA may adjust transmissions to suppress subcarriers used by the PU, including subcarriers in an SS-preamble, an SS short orthogonal frequency division multiplexing (OFDM) training field (SS-STF) symbol and an SS long OFDM training field (SS-LTF) symbol, and may reduce the physical (PHY) Layer Convergence Protocol (PLCP) Service Data Unit (PSDU) size.

摘要： Procedures enable multi-site aggregation (MSA) for a wireless transmit/receive unit (WTRU). MSA may be initiated by a macro cell or a small cell. A small cell evaluation procedure may be triggered at a WTRU based on information from a serving macro cell, which may include a list of available small cells within a coverage area of the macro cell. A WTRU may receive discovery signals from one or more small cells, and may perform inter-frequency measurements on the frequencies associated with the small cells in order to rank small cells. Procedures may enable a WTRU to transition between IDLE mode and Connected mode with MSA enabled. Other procedures support MSA including radio resource control (RRC) connection establishment and re-establishment in multi-layer operation, WTRU speed determination, connection request, admission control and resource negotiation, initial access, adding radio bearers across a small cell, and small cell and macro cell handovers.

摘要： A method and apparatus are described for performing channel aggregation to communicate over a non-contiguous spectrum, such as television white space (TVWS), using a plurality of aggregated channels including a primary channel and at least one non-primary channel (e.g., a secondary channel, a tertiary channel or a quaternary channel). Carrier sense multiple access (CSMA) may be performed on the primary channel to obtain access to the primary channel. After waiting an arbitration interframe space (AIFS) and potentially performing backoff on the primary channel, the aggregated channels may be used for transmission. A buffer controller may be used to create, for each of a plurality of access classes (ACs), a logic buffer for each of the channels. A frame controller may be used to provide the buffer controller with aggregated medium access control (MAC) protocol data unit (A-MPDU) frame information, and control aggregation and fragmentation processes.
