Modulated signal A is transmitted from a first antenna, and modulated signal B is transmitted from a second antenna. As modulated signal B, modulated symbols S2(i) and S2(i+1) obtained from different data are transmitted at time i and time i+1 respectively. In contrast, as modulated signal A, modulated symbols S1(i) and S1(i)′ obtained by changing the signal point arrangement of the same data are transmitted at time i and time i+1 respectively. As a result the reception quality can be changed intentionally at time i and time i+1, and therefore using the demodulation result of modulated signal A of a time when the reception quality is good enables both modulated signals A and B to be demodulated with good error rate performances.

A method includes: sending, by a first device, a first bit stream to a second device, where the first bit stream is sent over N logical lanes of a physical layer of the first device; sending, by the first device, a first trigger marker group to the second device, where the first trigger marker group is used to indicate that the sending of the first bit stream ends; and sending, by the first device, a second bit stream to the second device in response to the sending of the first trigger marker group, where the second bit stream is sent over P logical lanes of the physical layer of the first device, and both N and P are positive integers.

A method for data transmission includes: receiving a first indication message from a base station, wherein the first indication message includes first information indicating a Packet Data Convergence Protocol (PDCP) packet duplication function and at least two transmission entities configured for a radio bearer (RB) by the base station; setting a transmission function corresponding to the RB to be the PDCP packet duplication function according to the first indication message; setting a transmission entity corresponding to the RB according to the at least two transmission entities indicated in the first indication message; setting a present state of the PDCP packet duplication function, the present state being one of an activated state or a deactivated state; and performing data transmission according to the present state and the transmission entity.

A method for a user equipment (UE) to receive physical downlink control channels (PDCCHs) with a first sub-carrier spacing (SCS) includes receiving a bitmap indicating symbols of a slot that are first symbols of control resource sets (CORESETs) for PDCCH receptions, determining, based on the bitmap, a first number of symbols that is a smallest number of symbols in between a first symbol of PDCCH receptions in first CORESETs and a first symbol of PDCCH receptions in second CORESETs, determining, based on the first number of symbols and the SCS, a first maximum number of non-overlapping control channel elements (CCEs), and receiving the PDCCHs with the first SCS according to the first maximum number of non-overlapping CCEs.

Disclosed are techniques for wireless communication. In an aspect, a method, performed by a network node, for selection of uplink control information (UCI) transmission format, comprises determining whether to use a coherent transmission; upon determining to use a coherent transmission, selecting a coherent transmission format for UCI transmission. Upon determining not to use a coherent transmission the method further includes determining whether to use an orthogonal sequence: upon determining to use an orthogonal sequence, the method includes selecting a non-coherent transmission format with an orthogonal sequence for UCI transmission; upon determining not to use an orthogonal sequence, the method includes selecting a non-coherent transmission format with a non-orthogonal sequence for UCI transmission. The method further includes using the selected format for UCI transmission. For example, a base station may send the selected format for UCI transmission to a UE, or a UE may select and use the UCI transmission format.

A base station may receive uplink data identifying uplink performance indicators associated with user equipment connected to the base station, and may receive tuning factors associated with shared channel traffic received by the user equipment and quality of service requirements of the user equipment. The base station may determine a total score associated with utilizing a long duration physical uplink control channel (PUCCH) format for uplink control information based on the uplink data and the tuning factors. The base station may determine that the total score satisfies a threshold score and may switch to the long duration PUCCH format for the uplink control information based on the total score satisfying the threshold score. The base station may perform one or more actions based on switching to the long duration PUCCH format for the uplink control information.

Methods, systems and apparatus are described for enhanced node communication within a wireless node network having nodes and a server. The method begins with a first node associating with a second according to a server tracked logical connection authorized by the server. The first node captures relevant node information including shared data from another of the nodes. The first node transmits, when operating in a first connectivity mode, at least the shared data to the server using the second node operating as an intermediary for indirect communication with the server. The first node transmits, when operating in a second connectivity mode, at least the shared data to the server without using the second intermediary node by having the first node transmitting a message with at least the shared data to the server while avoiding the need to first send the message to the second node during transit to the server.

A method and a device for matching a quantization table of data representative of a radio signal received by a radio antenna of a mobile network. The method includes: obtaining an item of information representative of a channel decoding error rate of a decoded quantized demodulated signal from a demodulation of the radio signal received by the antenna, the demodulated radio signal having been quantized by the quantization table, and the quantized demodulated radio signal having undergone a channel decoding; matching the quantization table when the channel decoding error rate is higher than a determined threshold; and transmitting an item of information representative of the matching of the quantization table to a channel decoding device or to a demodulation device.

A distributed radio frequency communication system facilitates communication between a wireless terminal and a core network. The system includes a remote radio unit (RRU) coupled to at least one antenna to communicate with the wireless terminal. The RRU includes electronic circuitry to perform at least a first portion of a first-level protocol of a radio access network (RAN) for communicating between the wireless terminal and the core network. The system also includes a baseband unit (BBU) coupled to the core network, and configured to perform at least a second-level protocol of the RAN. A fronthaul link is coupled to the BBU and the RRU. The fronthaul link utilizes an adaptive fronthaul protocol for communication between the BBU and the RRU. The adaptive fronthaul protocol has provisions for adapting to conditions of the fronthaul link and radio network by changing the way data is communicated over the fronthaul link.
