Some embodiments provide a method for channel estimation in a wireless device. According to the method, the wireless device obtains (1010) an indication that a set of antenna ports, or antenna port types, share at least one channel property. The wireless device then estimates (1020) one or more of the shared channel properties based at least on a first reference signal received from a first antenna port included in the set, or having a type corresponding to one of the types in the set. Furthermore, the wireless device performs (1030) channel estimation based on a second reference signal received from a second antenna port included in the set, or having a type corresponding to one of the types in the set, wherein the channel estimation is performed using at least the estimated channel properties.

A wireless signal booster system and sensor processor for an IoT network is disclosed. An IoT Node contains one or more sensors, potentially a sensor processor or processing element and an IoT modem that can connect to the internet or a private IoT network to deliver data to an IoT hub application. The IoT node may also include one or more short range wireless links. The IoT node may communicate directly to a base station and through the base station be connected to the IoT network (which could be the Internet). Alternatively, the IoT node may connect to a base station through a repeater.

A network includes an intermediate node to communicate with a child node via a wireless network protocol. An intermediate node synchronizer in the intermediate node facilitates time synchronization with its parent node and with the child node. A child node synchronizer in the child node to facilitates time synchronization with the intermediate node. The intermediate node synchronizer exchanges synchronization data with the child node synchronizer to enable the child node to be time synchronized to the intermediate node before the intermediate node is synchronized to its parent node if the intermediate node has not synchronized to its parent node within a predetermined guard time period established for the child node.

When the base station (10-1) according to the present invention receives Muting Pattern Information which does not contain a Muting Pattern Offset, the base station (10-1) decides that the Muting Pattern Offset requested in a former request has been accepted.

The present disclosure discloses a method and a device in a User Equipment (UE) and a base station used for wireless communication. The UE first receives a first signaling and a second radio signal, and then transmitting a first radio signal on a sidelink. The first signaling is correlated to a first synchronization sequence. The first signaling is used for determining at least one of {first signature sequence, second synchronization sequence}. The first signature sequence is used for generating the first radio signal. The receiving timing of the second radio signal is used for determining the transmitting timing of the first radio signal. The second radio signal is associated with the second synchronization sequence. The first synchronization sequence differs from the second synchronization sequence. The first operation is transmitting, or the first operation is receiving. According to the present disclosure, both system performance and transmission efficiency are improved.

This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for orthogonal multiplexing of high efficiency (HE) and extremely high throughput (EHT) wireless traffic. Devices in a wireless local area network (WLAN) may operate under HE or EHT conditions. An access point (AP) may support both HE and EHT communications with WLAN devices. To enable substantially simultaneous downlink HE and EHT transmissions and substantially simultaneous uplink HE and EHT transmissions, the AP may support orthogonal frequency-division multiple access (OFDMA) of HE and EHT transmissions. For example, pre-HE and pre-EHT modulated fields, HE and EHT modulated fields, and payloads may be aligned in time for the HE and EHT transmissions. The AP may ensure orthogonality for multiplexing the HE and EHT transmissions based on the alignment. In some implementations, a trigger frame may be utilized to indicate uplink transmission alignments.
