  • Publication number: 20140204911
    Abstract: A method of wirelessly transmitting control information includes generating control information comprising a plurality of control bits and encoding the control bits using a block code that outputs an encoded bit sequence comprising encoded bits b(0), b(1), . . . , b(19). The control bits are encoded using the block code by generating a linear combination of a plurality of basis sequences. The method also includes dividing the encoded bits into a first group and a second group. The first group includes the encoded bits {b(0), b(1), b(5), b(6), b(8), b(11), b(12), b(14), b(17), b(19)} and the second group includes the encoded bits {b(2), b(3), b(4), b(7), b(9), b(10), b(13), b(15), b(16), b(18)}. Additionally, the method includes transmitting the first group of encoded bits on a first set of carriers and transmitting the second group of encoded bits on a second set of carriers. The second set of carriers have different frequencies from the first set of carriers.

  • Patent number: 8780688
    Abstract: The present invention relates to methods and apparatus in a RBS and a UE for reference signal (RS) measurements in an OFDM system, that enable having a configurable RS transmission bandwidth which is smaller than the system bandwidth. This allows for better interference coordination of RS, which in turn improves the UE RS measurements used for different services such as positioning. The RBS retrieves the RS transmission bandwidth, determines a RS measurement bandwidth based on this RS transmission bandwidth, and transmits the determined bandwidth to the UE. The UE receives the RS measurement bandwidth and measures the RS in a bandwidth determined based on the received measurement bandwidth and the UE capability.

  • Publication number: 20140185589
    Abstract: Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits. The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence across Discrete Fourier Transform Spread-Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The UE further transforms the block-spread sequence, per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.

  • Publication number: 20140153483
    Abstract: A Level-1 (L1) signaling flag is mapped to unused (invalid) bit sequences in Part 1 of the HS-SCCH—that is Part 1 bit encodings that are not defined in the UTRAN specifications—and a corresponding L1 command is encoded in Part 2. This allows UE (18) to detect early that the HS-SCCH is pure L1 signaling, and the UE (18) may avoid, wasting power by not processing an accompanying HS-PDSCH. Alternatively, in CPC HS-SCCH-less mode, the UE (18) may blind decode the HS PDSCH. In one embodiment, a general DRX mode is defined and controlled via L1 signaling. In one embodiment, a UE (18) acknowledgement improves the L1 signaling accuracy. In one embodiment, a L1 signal and UE (18) acknowledgement protocol are utilized to “ping” a UE (18).

  • Patent number: 8744481
    Abstract: Method and arrangement in a first node for providing geographical position related information. The first node and a second node are comprised within a wireless communication system. The first node and the second node are adapted to exchange wireless signals. The method comprises receiving a signal from the second node. Apart of the received signal that has propagated through a first channel path from the second node is detected by using a circular correlator. A timing estimate associated with the propagation time of the part of the signal which is received over the first channel path from the second node is calculated. Thus the calculated timing estimate is provided, which timing estimate is to be used when determining the geographical position.

  • Patent number: 8738983
    Abstract: The present invention relates to methods and arrangements that enable continuous adaptive control of the number of autonomous HARQ retransmissions. This is achieved by a solution, where the UE and the radio base station are using a number of autonomous HARQ retransmissions that can be adjusted based on observations in the UE and/or the radio base station. What is observed is the amount of HARQ retransmissions needed for the radio base station to correctly decode the latest received data packet(s).

  • Publication number: 20140141792
    Abstract: The present invention relates to a base station (BS) and to a method for supporting UE positioning measurements in a wireless communication system. The method comprises transmitting (610) signals associated with a first cell, where the signals comprise positioning reference signals. The method also comprises transmitting (620) signals associated with a second cell, wherein the second cell is configured to have a lower transmission capacity than the first cell, and discontinuing (630) the transmission of at least one signal associated with the first cell except for the positioning reference signals. The energy consumption of the BS may thus be reduced while still supporting accurate positioning measurements.

  • Patent number: 8705434
    Abstract: The present invention relates to methods and arrangements that make it possible to control the delay for the UEs to access the EUL resources in the Enhanced Uplink in CELL_FACH state procedure, independently from the delay for the UEs to access 5 ordinary UL resources in the RACH procedure. This is achieved by a solution where the timing of entering (or re-entering) a transmission procedure for Enhanced Uplink in CELL-FACH state is controlled with the help of a transmission control parameter defined specifically for this transmission procedure, instead of using the same parameter as for the RACH procedure.

  • Publication number: 20140036844
    Abstract: A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—?F—PUCCH(F)—are also provided for use with PUCCH format 3.
