  • Publication number: 20130016694
    Abstract: A method and apparatus for generating a single statically defined downlink reference MCS table consisting of transport block sizes (TBSs) computed for 29 MCSs for each of j PRBs where j=1, . . . , NRBDL. Three entries of the MCS table are reserved for implicit modulation order signaling (e.g. in the downlink) or implicit redundancy version signaling (e.g. in the uplink). Each MCS entry in the table is populated by a TBS and the table entries are accessed based on a 5-bit MCS index and resource allocation information, indicating the number of PRBs is signaled via a scheduling message which may be a grant or assignment message. A grant or assignment message may further include a 5-bit MCS field for each transport block which, along with the resource allocation information, enables the UE to determine the scheduled TBS.

  • Patent number: 8356232
    Abstract: A method and apparatus for turbo coding and decoding is provided herein. During operation, a concatenated transport block (CTB) of length X is received and a forward error correction (FEC) block size KI is determined from a group of available non-contiguous FEC block sizes between Kmin and Kmax, and wherein Kmin?KI<Kmax and wherein KI is additionally based on X. The concatenated transport block of length X is segmented into C segments each of size substantially equal KI. An FEC codeword for each of the C segments is determined using FEC block size KI; and the C FEC codewords are transmitted over the channel.

  • Publication number: 20120281593
    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.

  • Publication number: 20120257519
    Abstract: A method and apparatus for a co-scheduler can mitigate UE-to-UE adjacent carrier frequency band interference by allocating three sets to a first user equipment uplink. Each set has at least one sub-carrier in a first frequency band, at least one uplink time period, and at least one transmission power parameter. The co-scheduler initially allocates the first set. The co-scheduler allocates the second set in response to detecting a second user equipment operating proximal to the first user equipment, and the second set differs from the first set in either at least one sub-carrier or at least one transmission power parameter. The co-scheduler allocates the third set in response to detecting that the second user equipment is no longer operating proximal to the first user equipment, and the third set differs from the second set in either at least one sub-carrier or at least one transmission power parameter.

  • Patent number: 8194603
    Abstract: A wireless base unit (102) supporting carrier aggregation determines a truncation time period (159, 169) in order to create a reduced subframe component (154, 164) on an additional component carrier (120) such that the truncated subframe component (154, 164) does not interfere with the control region (171, 172) of a subframe (170, 180) transmitted on an overlapping component carrier (130) by an uncoordinated second base unit (105). The wireless base unit (102) transmits the truncated subframe component (154, 164) and also transmits truncation time period information within a control region (151, 161) of an anchor carrier (110). A remote terminal (104, 108) that supports carrier aggregation searches a control region (151, 161) of a subframe (150, 160) transmitted on the anchor carrier (110) for truncation information and uses the truncation information to determine a boundary of a data region in a subframe component (154, 164) received on the additional component carrier (120).

The processor encodes the reference signal into a first set of transmission resources, encodes other information into a second set of transmission resources, and multiplexes the two sets of transmission resources into a subframe, such that the first set of transmission resources is multiplexed into at least a portion of a first set of orthogonal frequency division multiplexed (OFDM) symbols based on an identifier associated with the base station and the second set of transmission resources is multiplexed into a second set of OFDM symbols. The transmitter transmits the subframe to the wireless devices. According to one embodiment, transmission resources for carrying the reference signal may be allocated according to a predetermined allocation, a semi-static allocation, a dynamic allocation, and/or an allocation based on higher layer signaling.
