摘要:
A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (770). A control field (1103) may be sent with a payload field (1105) wherein the control field (1103) and payload field (1105) are sent using a single Orthogonal Variable Spreading Factor or a single Walsh Code (1101) wherein various modulation and coding schemes may be applied to the control field (1103) and payload field (1105) such that different modulation and coding schemes may be used within the single channel. HARQ is handled by sending a single retransmission if a NACK message is received or no ACK/NACK message is received at all.

Disclosed is a method for mobile assisted sleep mode to reduce current drain in packet based mobile systems. The method comprising the step of receiving (102) from a network a channel condition threshold. Then, monitoring (104) a channel condition while in sleep mode. Then exiting (110) sleep mode in response to the determination (108) that the monitored channel condition is greater than the channel condition threshold.

A wireless communication terminal that communicates on a plurality of sub-carriers divided into a plurality of frequency bands, wherein each frequency band includes at least one sub-carrier. The terminal measures a channel quality indicator (CQI) for a plurality of frequency bands, identifies a subset of frequency bands for which the channel quality indicator has been measured based on a subset criterion, and transmits a report identifying a subset of frequency bands for which a channel quality indicator has been measured or frequency bands not in the subset. In some embodiments, the report also includes a subset CQI value associated with at least the subset of frequency bands identified.

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.

A communications system for reducing bit errors in a received data sequence provides a method for generating candidate code-word sequences for evaluation by a CRC decoder. The system may determine a most-likely received sequence using the probable code-word list of candidate sequences. The number of candidate sequences may be reduced using computational complexity reduction methods. A communications device also provides a candidate sequence generator for use with a CRC decoder to determine a most-likely received sequence and to reduce bit errors in a received sequence.

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.
摘要:
An improved turbo code based incremental redundancy includes a first step of puncturing a data stream for a first transmission to provide a set of first unpunctured trellis sections. A next step includes puncturing a data stream for a second transmission to provide a set of second unpunctured trellis sections. A next step includes incremental redundancy combining the first and second transmissions of the trellises to provide non-adjacent first and second unpunctured trellis sections. The above arrangement results in a uniform distribution of punctured and unpunctured bits to provide lower errors.
摘要:
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.
