Abstract:
A method and apparatus for performing mobility measurement in a communication network (100) is described. The method comprises of receiving a subframe sequence pattern from a node in the communication network (100). The subframe sequence pattern indicates types of subframes being transmitted by a neighboring cell node (104) in a neighboring cell (112). The method includes receiving a subframe from a sequence of subframes transmitted by the neighboring cell node (104) in the neighboring cell (112), and determining that the received subframe is a multicast subframe based on the subframe sequence pattern. The method then includes performing a single cell-specific reference symbol measurement in response to determining that the received subframe is the multicast subframe.
Abstract:
Disclose is a synchronized wireless communication network (100) operating in single frequency network mode comprising a first base station (502) broadcasting, on a first channel, broadcast data and a common sequence (508) that is generated from a first channel identifier, and wherein the first base station transmits data on a common control channel. A second base station (510), adjacent to the first base station and synchronized with the first base station, the second base station simultaneously broadcasting on the first channel the broadcast data and the common sequence, and wherein the second base station transmits data on a common control channel.
Abstract:
A method of modulation detection. A signal is received (710). A first decision statistic can be generated based on the received signal (720). The received signal can be transformed (725). A second decision statistic can be generated based on the transformed received signal (735). A selected modulation type can be determined based on comparing the first decision statistic with the second decision statistic (740).
Abstract:
A wireless communication device (200) including a first CRC coder that generates a first block of CRC parity bits on a transport block and associates the first block of CRC parity bits with the transport block, a segmenting entity that segments the transport blocks into multiple code blocks after associating, and a second coder that generates a second block of CRC parity bits on each code block and associates a second block of CRC parity bits with each code block. The first and second blocks of CRC parity bits are based on first and second generator polynomials. In one embodiment, the first and second generator polynomials are different. In another embodiment, the generator polynomials are the same and the transport block is interleaved before segmenting or the code block are interleaved before encoding with the second block of CRC parity bits.
Abstract:
The present invention provides a method for transmitting broadcast channel information as part of a broadcast channel signal having one or more transmission intervals, where each transmission interval includes a plurality of transmissions, and one or more of the transmissions are active frames in which broadcast channel information is transmitted. Invariant portions that are present in the broadcast channel information are identified separate from any variant portions and are encoded for transmission, and the variant portions are used to select transmission specific configurations, which can be detected during the decoding by the receiver. Upon detection of the transmission specific configuration used to encode the invariant portions, the value of the variant portion can be identified and reintroduced as part of the received broadcast channel information.
Abstract:
A wireless communication device for receiving a frame (200) corresponding to a transmission time interval, the frame having a control channel (210) including at least two control channel elements (212, 214) and an embedded bit sequence, the location of which indicates a portion of the control channel used for radio resource assignment, wherein the portion of the control channel used for radio resource assignment may be less than the entire control channel of the frame having the embedded bit sequence, and wherein the at least two frames may use different portions of the control channel for radio resource assignment.
Abstract:
An apparatus and method for receiving a message stream on a channel (140). A message (160) is received (320) on the channel. Information regarding the bits of a successfully decoded message is added (340) to a message attributes list (275) if the message is successfully decoded. An attempt is made to decode (330) a subsequent message based on the information in the message attributes list.
Abstract:
A wireless communication network entity (400) and a method therein wherein data is encoded using an error correcting code to form a first codeword, for example, a cyclic redundancy code, including redundancy. A second codeword is generated by encoding additional data on a portion of the first codeword, wherein the portion of the first codeword on which the additional data is encoded being within an error correction capability of the first codeword.
