Abstract: User equipment determines a transport block size column indicator representative of a number of resource blocks based on a number of allocated resource blocks, an adjustment factor, and a limiting factor. The transport block size column indicator is determined by applying the adjustment factor to the number of allocated resource blocks and comparing a result of applying the adjustment factor to the number of allocated resource blocks to the limiting factor. The transport block size column indicator is selected as either the result or the limiting factor based on the comparison.

Abstract: A method and apparatus provide reception of control signaling in a wireless communication network. A preamble transmission can be detected from a second device in a first set of at least one Orthogonal Frequency Division Multiplexing (OFDM) symbol starting with a first OFDM symbol in a subframe received on a secondary serving cell operating on an unlicensed carrier, the first OFDM symbol having a first Cyclic Prefix (CP). A second OFDM symbol in the subframe can be determined such that the second OFDM symbol immediately follows the first set of OFDM symbols. Downlink Control Information (DCI) containing a Physical Downlink Shared Channel (PDSCH) resource assignment can be decoded in a second set of OFDM symbols beginning with the second OFDM symbol, the second set of OFDM symbols having a second CP. The duration of the first CP is larger than the duration of the second CP.

The PDSCH can be decoded based on at least the determined type of truncation of the subframe.

Abstract: A method and apparatus schedule user equipment uplink transmissions on an unlicensed carrier. A configuration indicating a window length can be received from a higher layer, where the higher layer can be higher than a physical layer. A grant can be received in a subframe, where the grant can be for transmitting a physical uplink shared channel on a serving cell operating on an unlicensed carrier.

Listen before talk can be performed on the unlicensed carrier to determine an earliest unoccupied subframe in the set of subframes. The physical uplink shared channel can be transmitted in the earliest unoccupied subframe in response to receiving the grant.

Abstract: A User Equipment (UE) can receive Downlink Control Information (DCI) from a base station. The DCI can contain a Channel State Information (CSI) request on a physical control channel in a subframe of a first serving cell. The CSI request can direct the UE to perform CSI measurements for at least one aperiodic Channel State Information Reference Signal (CSI-RS) of a second serving cell. The UE can ascertain CSI-RS resources in a subframe of the second serving cell based on at least the DCI contents. The UE can determine CSI based on the ascertained CSI-RS resources. The UE can send the determined CSI to the base station.

Abstract: A UE can receive Zero Power Channel State Information Reference Signal (ZP-CSI-RS) configuration information for an aperiodic ZP-CSI-RS of a serving cell. The UE can receive Downlink Control Information (DCI) on a physical control channel in a subframe of the serving cell. The DCI can indicate whether a Physical Downlink Shared Channel (PDSCH) of the UE in the subframe of the serving cell is rate-matched around resource elements indicated by the ZP-CSI-RS configuration information. The UE can decode the PDSCH in the subframe of the serving cell based on rate-matching around the resource elements indicated by the ZP-CSI-RS configuration when the DCI indicates the PDSCH of the UE is rate-matched around the resource elements indicated by the ZP-CSI-RS configuration.

Abstract: A broadband cellular network (BCN) provides a user equipment (UE) access to TVWS resources. The BCN authorizes the UE to access TVWS resources by conveying a mobile device identifier received from the UE, and a cell identifier associated with the UE's coverage area, to a Federal Communications Commission (FCC)-certified Database and receiving, from the Database, and storing an FCC ID associated with the UE and a set of available TVWS resources. The BCN then conveys, to the UE via a broadband cellular technology, a channel resource information element (CRIE) that includes the cell identifier and identifies the set of available TVWS resources. Subsequently, the BCN re-authorizes the UE to access TVWS resources based on the stored FCC ID and without re-conveying the mobile device identifier to the Database. The BCN further utilizes broadband cellular technology procedures to provide a “virtual” contact verification signal (VCVS) to the UE.

Abstract: Various methods and apparatuses for receiving a control channel involve a communication device monitoring a first control and receiving information from a network regarding the configuration of a second control channel. The communication device receives an uplink grant from the network; transmits a message to the network, in which the message indicates to the network that the communication device is capable of monitoring the second control channel. The communication device monitors the second control channel based on the configuration information receiving via the first control channel.

Abstract: Briefly, the present disclosure is directed to methods and apparatus that allow for the synchronization with, and measurement reporting of, unlicensed frequency carriers. A method and apparatus for synchronizing to an Scell operating on an unlicensed carrier determine, at a UE (108, 116), one or more measurement instances where a discovery signal may be transmitted, for example, by a base station (132), on the Scell from a higher layer configuration message. The method and apparatus may monitor a control channel for a control channel message and determine whether the discovery signal will be transmitted during one or more measurement instances on the Scell. The method and apparatus may detect the discovery signal transmission on the Scell during one or more of the measurement instances. The method and apparatus may also synchronize to and/or measure the Scell based on detected discovery signal transmissions.

Abstract: A system and method for neighbor-cell measurement reporting in a cellular environment supporting multistate cells limits measurement reporting by requiring that state-specific trigger conditions are met. Thus for example, a dormant cell may need to meet more stringent measurement conditions before a report is generated by the user device, since a current primary cell may prefer to hand off to an active cell. In particular, state-specific thresholds, offsets, and hysteresis values may be used to enforce a preference for active cells, for example.

Abstract: A communication system is provided wherein a user equipment (UE) receives control information from a wireless network. The UE monitors control channel candidates using common reference signals (CRS) and monitors enhanced control channel candidates using demodulation reference signals (DMRS) when the UE is configured in a first transmission mode, such as transmission mode 9, for receiving a downlink shared traffic channel based on DMRS. The UE monitors control channel candidates only using CRS when the UE is configured in a second transmission mode, such as any of transmission modes 1-6, for receiving a downlink shared traffic channel based on CRS. The UE then receives downlink control information (DCI) in a subframe in one of the monitored control channel candidates or enhanced control channel candidates in the subframe.

Abstract: A first user equipment (UE) and a second UE communicate with a network element (e.g., an eNB) over a carrier (e.g., an uplink or downlink cellular carrier). The first and second UEs also engage in D2D communication using resources of the carrier that have been allocated to them by the network entity. Using the allocated resources, the first and second UEs communicate using a subframe that has a first set of symbols in during which the first UE transmits, a second set of symbols during which the second UE transmits, and a guard interval between the first and second UEs.

Abstract: Various methods for controlling an aggressor user equipment (UE) can use two transmission power control loops to mitigate UE-to-UE adjacent carrier frequency band interference to a geographically proximal victim UE. The aggressor UE can select between different transmission power parameters based on two (or more) power values. The usage of any particular power value depends on the time period of the transmission. For example, if a proximal victim UE is scheduled to receive when the aggressor UE is scheduled to transmit, a lower power value may be selected as instructed by a co-scheduler or determined by the aggressor UE. The aggressor UE can also send dual power headroom reports to its serving base station based on the two power values.
