摘要： A method in a node is disclosed. The method comprises receiving a signal, and obtaining a first oversampled received signal by sampling the received signal according to a symbol rate. The method further comprises estimating a first frequency offset based on the first oversampled received signal, the first frequency offset estimated using an estimation range limited to one of a bandwidth of the received signal or the symbol rate of the received signal, and obtaining a second oversampled received signal by sampling the received signal according to N times the symbol rate, wherein N is greater than 1. The method further comprises estimating a true frequency offset based on the first frequency offset estimate and the second oversampled received signal.

摘要： Embodiments presented in this disclosure relate to methods and apparatuses (such as Access Points (AP's), evolved NodeB's (eNB's), etc.) for use in aggregation, or integration, between a Wireless Wide Area Network (WWAN) and a Wireless Local Area Network (WLAN). In one embodiment, an eNB decides that an aggregation between the WWAN and the WLAN is to be performed for at least one bearer of one or more bearers associated with a specific UE. Next, the eNB identifies which one(s) of the at least one bearer of the specific UE that is/are to be aggregated between the WWAN and the WLAN. Also, the eNB schedules each one of the at least one bearer identified to be aggregated between the WWAN and the WLAN.

摘要： A signal is received containing a block of multiple symbols, each symbol containing information bits spread by a spreading sequence of chips. Each spreading sequence is determined by a channelization sequence and a first or second complex-valued scrambling sequence of chips. Each block is processed using a set of spreading sequences using correlations between pairs of spreading sequences in the set. Spreading sequence correlation values between each pair are manipulated and stored in lookup tables. A lookup table address is determined using a first set of reduced basic scrambling bits to retrieve correlation values. The first set of reduced basic scrambling bits is based on manipulation of one set of the basic scrambling bits that reduces a number of bits included in the determined address to less than a number of binary values in the one set of basic scrambling bits. The one set of basic scrambling bits is used to construct one of the first and second complex-valued scrambling sequences. The retrieved correlation values may be used in mitigating spreading sequence correlation interference between spreading sequences in the set.

摘要： The present invention relates to a method of producing a chip block for wireless transmission in a Direct Sequence Code Division Multiple Access (DS-CDMA) communication system. The method comprises spreading a symbol over at least one chip block (17). The method also comprises segmenting the chip block to form a first sub-block (a0) of the chip block. The method also comprises segmenting the chip block to form a second sub-block (a15) of the chip block. The method also comprises arranging a first sub-sequence (18) of chips furthest to a first end of the chip block in the first sub-block. The first sub-sequence is identical to a second sub-sequence (19) furthest to a second end of the chip block in the second sub-block. The method also comprises modifying at least one chip contained in the first sub-block and not being part of the first sub-sequence. The modifying is dependent on said first sub-sequence such that the symbol can be at least partially despread from the chip block.

摘要： In a receive node (230) of a wireless network (100), an iterative multi- user multi-stage interference cancellation receiver (400, 800, 1100) is used. After each stage of interference cancellation, interference characteristics change. An adaptive finger placement strategy is used in which after each stage of interference cancellation, finger delays and combining weights of the receiver (400, 800, 1100) are adapted to reflect the changed interference characteristics.

摘要： In a receive node (230) of a wireless network (100), an iterative multi-user multi-stage interference cancellation receiver (500, 1400, 1700) is used. The receiver (500, 1400, 1700) performs code-averaged equalization and chip chip-level code-specific interference over-cancellation on the received signals. This can result in a unified interference cancellation processing, and can avoid cumbersome calculations of code cross correlations that is required in symbol-level interference cancellation. A symbol-level code-averaged desired signal add-back is performed to address the over- cancellation of some desired signals.
