CPC Class H04W

A method of encoding a first bit and a second bit for transmission on a transmission band is provided. The method includes receiving a bit stream that includes the first and second bits, mapping the first bit into a first symbol, mapping the second bit into a second symbol, differentially encoding at least the first symbol and the second symbol, and causing the first and second symbols to be transmitted on a transmission band as part of a symbol stream.

A method and apparatus for transmitting a frame on the basis of a sounding procedure is disclosed. The method for transmitting the frame on the basis of a sounding procedure in a wireless LAN may comprise the steps of: transmitting an NDPA frame to each of multiple STAs by an AP wherein the NDPA frame notifies of the transmission of NDP; transmitting the NDP to each of the multiple STAs by the AP; receiving, by the AP, multiple feedback frames transmitted through multiple transmission sources allocated to the multiple STAs in time sources overlapped by the multiple STAs, respectively; and transmitting, by the AP, multiple downlink frames to the multiple STAs respectively.

A method and apparatus for allocating resources for a machine type communication user equipment (MTC UE) in a wireless communication system is provided. A base station indicates a transport block size (TBS) directly, adapts a code rate according to repetition numbers across multiple subframes in a MTC physical downlink shared channel (M-PDSCH) for the MTC UE, and allocates resources for the M-PDSCH by using the indicated transport block size and the adapted code rate. The TBS may be determined based on a modulation and coding scheme (MCS) only.

A system, method (400), and network node (102) is presented for setting the size of a control region, the PDCCH region (201) of a subframe (200). The PDCCH control region may have a size, indicated by the Control Format Indicator, CFI, transmitted on the PCFICH, that varies between 1 and 3 OFDM symbols. The network node (102) may select (402) an initial size for the control region (201), and determine (404) whether the initial size for the control region is less than a predetermined maximum control region size. In response to determining that the initial size is less than the predetermined maximum control region size, the network node (102) selects (406) a final size for the control region (201) based on a data region load. The data region load indicates a load on all physical downlink shared channels, PDSCHs, on all enhanced PDCCHs, ePDCCHs, in the data region. After selecting the final size for the control region, the network node (102) transmits (408) the subframe (200), wherein the control region of the subframe comprises information identifying the selected final size, and the size of the control region is equal to the selected final size.

Techniques described herein assist with indicating whether ACK/NACK signaling is present in an uplink transmission, thereby enhancing performance by permitting use of rate matching while reducing decoding errors. For example, a user equipment may determine whether ACK/NACK signaling is to be included in an uplink transmission in a portion of uplink resources allocated for a data channel, may generate a reference signal that indicates whether the ACK/NACK signaling is present in the uplink transmission, and may transmit the reference signal.

A method, system and apparatus are disclosed. A wireless device (WD) configured to communicate with a network node is provided. The WD configured to, and/or comprising a radio interface and/or processing circuitry configured to receive a Downlink Control Information (DCI) message for scheduling transmission on a Physical Uplink Shared Channel (PUSCH) in which the DCI message not containing an indication of how many resources to reserve for Hybrid Automatic Repeat Request (HARQ) bits, and optionally, transmit on the scheduled PUSCH based on the DCI message.
