In one embodiment, a method for the transmission of information in a wireless communication system comprises receiving a downlink message, wherein the downlink message includes a first control channel element; determining a first index using the location of the first control channel element; determining a second index; determining a first orthogonal resource using the first index; determining a second orthogonal resource using the second index; spreading an uplink message using the first orthogonal resource to form a first spread signal; spreading the uplink message using a second orthogonal resource to form a second spread signal; transmitting the first spread signal using a first antenna; and transmitting the second spread signal using a second antenna. | 07-10-2014 |
20140233495 | Reporting Power Headroom for Aggregated Carriers - A method for reporting power headroom-related information for a plurality of aggregated carriers. The method includes reporting in a bitmap the power headroom-related information for a number of the aggregated carriers that is less than or equal to the total number of aggregated carriers, wherein the power headroom-related information is one of a power headroom for at least one of the aggregated carriers and a path loss for at least one of the aggregated carriers. | 08-21-2014 |
20140233534 | Message Rearrangement for Improved Wireless Code Performance - A system and method for permuting known and unknown message bits before encoding to provide a beneficial rearrangement of bits. Such a method can improve distance properties in the resulting subcode. In various embodiments, the structure of a beneficial rearrangement is dependent on the parameters of how known and unknown bits are grouped and on the specific type of code being used. Given these two parameters, the message bits can be rearranged to more efficiently leverage any apriori knowledge. | 08-21-2014 |
20140247763 | Discontinuous Reception Start Offset Coordinated with Semi-Persistent Scheduling System and Method - An apparatus and method are provided for configuring a user agent to receive semi-persistent scheduling (SPS) transmissions independent of the user agent monitoring a physical downlink control channel (PDCCH). Also provided are an apparatus and method for configuring a user agent to monitor a PDCCH in a subframe to which one of a downlink assignment or an uplink grant is configured. | 09-04-2014 |
20140254521 | System and Method for Multi-Carrier Network Operation - A system and method for configuring a component carrier is presented. A component carrier assignment message is received. The component carrier assignment message may be configured to identify the component carrier and include at least one of, at least one of a downlink carrier frequency, a carrier frequency of a paired uplink carrier, a bandwidth of the component carrier, and a bandwidth of the paired uplink carrier, an indication of whether the component carrier is a control channel monitoring component carrier configured to signal data channel assignment information for the component carrier, and a logical index of the component carrier. The component carrier assignment message may then be used to configure the component carrier on a user equipment (UE). | 09-11-2014 |
20140269585 | Downlink Control Information Set Switching When Using Carrier Aggregation - A method and apparatus for reconfiguring a user equipment configured for multi-carrier operation from a first downlink control information set to a second downlink control information set while carrier aggregation is being used, including receiving a physical downlink control channel with downlink control information formats containing a carrier indicator field. | 09-18-2014 |
20140293883 | COMMUNICATION IN THE PRESENCE OF UPLINK-DOWNLINK CONFIGURATION CHANGE - Data is communicated between a network node and a user equipment in a first frame according to a first uplink-downlink configuration. In response to a configuration change that causes a second frame following the first frame to be according to a second, different uplink-downlink configuration, an acknowledgement indication for the data is sent in the second frame. | 10-02-2014 |
20140307676 | System and Method for Uplink Control Information Transmission in Carrier Aggregation - A method for communicating uplink control information to a base station using a user equipment is presented. The method includes identifying component carriers on the user equipment scheduled for Physical Uplink Shared CHannel (PUSCH) transmissions, and identifying at least one first ranking for each of the component carriers for transmission of uplink control information. Each first ranking is at least partially determined by whether the component carrier is configured for delay-sensitive transmissions. The method includes using the at least one first ranking to select a first component carrier for transmission of uplink control information, and encoding uplink control information into the first component carrier for transmission to the base station. | 10-16-2014 |
