摘要:
Transmitting a acknowledge/not acknowledge (ACK/NACK) response in a wireless cellular network by mapping the data value into a cyclic shifted version of a reference signal. A subframe is formed with a plurality of symbols with certain symbols designated as reference signal (RS) symbols. The receiver and transmitter both know when an ACK/NACK response is expected. If an ACK/NACK response is not expected, then an RS is inserted in the duration of symbols designated as RS symbols. If an ACK/NACK response is expected, then the ACK/NACK response is embedded in one or more of the symbols designated as RS symbols. The subframe is transmitted to a receiver, and the receiver can determine the ACK/NACK value in the RS symbol, if present, and also use the RS symbol for coherent demodulation of a CQI (channel quality indicator) or data.

Transmission of information in a wireless network is performed by allocating a channel from a transmitter to a receiver. The channel has at least one time slot with each time slot having a plurality of symbols. Each slot contains at least one reference symbol (RS). As information becomes available for transmission, it is classified as prioritized information (PI) and other information. One or more priority symbols are generated using the digital samples of the priority information. Other symbols are generated using the other data. Priority symbols are transmitted on the channel in a manner that separation of priority symbol(s) and a reference symbol does not exceed a time duration of one symbol. For example, Rank Indicator (RI) is transmitted using symbol k, ACKNAK is transmitted using symbol k+1; and the reference signal (RS) is transmitted using symbol k+2, wherein symbols k, k+1, and k+2 are consecutive in time. The other symbols are transmitted in available locations.
摘要:
A transmission within a wireless cellular network may include a first and second type of information. A subframe includes a plurality of symbols, at least one symbol is designated as a data symbol and at least one symbol is designated as a reference signal symbol that contains a pre-defined reference signal. The first type of information is embedded in the data symbols. If the second type of data is expected, then the second type of information is embedded in at least one reference symbol by quadrature amplitude modulating the pre-defined reference signal. The subframe is then transmitted from one node in the network to a second node. If it is determined that the second node is not expecting the second type of information, then a discontinuous transmission (DTX) response is embedded in the reference symbol instead of the second type of information.

A transmission of information within a wireless cellular network may include a first and second type of information. A subframe is produced that includes a plurality of symbols, wherein at least one symbol is designated as a data symbol and at least one symbol is designated as a reference signal symbol that contains a pre-defined reference signal. The first type of information is embedded in the data symbols. If the second type of data is expected, then the second type of information is embedded in at least one reference symbol by quadrature amplitude modulating the pre-defined reference signal. The subframe is then transmitted from one node in the network to a second node. In some embodiments, if it is determined that the second node is not expecting the second type of information, then a discontinuous transmission (DTX) response is embedded in the reference symbol instead of the second type of information.

Within a wireless network, uplink control information (UCI) transmitted by user equipment is received by a base station. The UCI includes a least two elements, a first set of symbols produced using a first information element and a second set of symbols produced using a second information element. At least a first metric is produced using the first set and the second set of received symbols. The first information element may then be detected using the first metric.

A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations. The transmission from the secondary to primary node in a wireless network is performed by first receiving an allocation of M>1 reverse link channels for transmission of N>0 information elements. N information elements are produced. A group of K (possibly only one) reverse link channels is selected from the M allocated reverse link channels, using at least one of the N produced information elements, wherein the group of K reverse link channels comprises at least one channel, such that 0

The links and chains (LNC) of this invention is an applications verification and validation (AVV) methodology. LNC is a hierarchical and systematic approach emphasizing conservation and reuse of effort expended. LNC creates objective metrics for validation. This invention ensures that the device will work in a system environment. LNC is an independent and complementary validation of the design before committing release to tape-out. The chip support library (CSL) and diagnostics used by LNC are natural outputs of the validation and are thus gating items to tape-out release. This ensures a fully tested device.

A method of wireless communication including a plurality of fixed base stations and a plurality of mobile user equipment with each base station transmitting to any user equipment within a corresponding cell a sounding reference signal sub-frame configuration indicating sub-frames when sounding is permitted. Each user equipment recognizes the sounding reference signal sub-frame configuration and sounds only at permitted sub-frames. Differing cells may have differing sounding reference signal sub-frame configurations. There are numerous manners to encode the transmitted information.
摘要:
A method of mapping data in a wireless communication system is disclosed. The method includes forming a first frame (504) having plural positions at a first transmitter (eNB 1, 200). The first frame has a first plurality of reference signals (500). A second frame (508) has plural positions corresponding to the plural positions of the first frame and is formed at a second transmitter (eNB 2, 450) that is remote from the first transmitter. The second frame has a second plurality of reference signals (506). A plurality of data signals (S1, S2) is inserted into the first frame at positions that are not occupied by either the first or second plurality of reference signals. The plurality of data signals (S1, S2) is inserted into the second frame at positions that are not occupied by either the first or second plurality of reference signals. The first and second frames are transmitted to a remote receiver (UE 1, 106).
