A method for establishing a communication connection and related products are provided. The method is applicable to a terminal. The terminal is in communication connection with a first earphone of wireless earphones. The first earphone is in communication connection with a second earphone of the wireless earphones. The method includes the following. A first distance between the terminal and the first earphone, a second distance between the terminal and the second earphone, and a third distance between the first earphone and the second earphone are determined. The communication connection between the terminal and the first earphone is disconnected when the first distance is greater than the second distance and the third distance is greater than or equal to a first threshold value. A communication connection between the terminal and the second earphone is established.

Embodiments of the present invention provide a participant of a communication system, wherein the communication system communicates wirelessly in a frequency used by a plurality of communication systems, wherein the participant is configured to transmit data uncoordinatedly with respect to other participants and/or a base station of the communication system, wherein the participant is configured to receive a synchronization data packet of a point-to-multipoint data transfer of the base station of the communication system, wherein the synchronization data packet is transferred in a frequency range of the frequency band of the communication system that is specified or known to the participant, wherein the participant is configured to receive, on the basis of the synchronization data packet, a payload data packet of the point-to-multipoint data transfer that is referenced in time and/or frequency to the synchronization data packet.

Coverage enhancements and coverage mode switching related optimizations are discussed for user equipments (UEs) that may switch between various coverage extension (CE) and non-CE modes of operation. In such enhancements, paging uncertainty and delays may be reduced by sending pages either simultaneously or using historical information over multiple coverage modes available to UEs. Random access procedures may be improved by providing CE mode random access procedures that are available when normal mode random access attempts fail and before declaring radio link failure. Additional aspects include improvements for more advanced UEs to improve coverage within normal mode operations by leveraging techniques used for narrowband CE mode operations, including transmission repetition and gapless transmission scheduling over hopped narrowband frequencies.

Sharing of frequency generator settings in a network are disclosed. In a particular implementation, a method of wireless communication includes determining, by a user equipment (UE), a first frequency setting for a frequency generator of a UE. The first frequency setting is associated with a first frequency. The method includes modifying the first frequency setting to generate a second frequency setting for the frequency generator. The second frequency setting is associated with a second frequency that is different from the first frequency. The method also includes generating a message that indicates the second frequency setting. The method further includes transmitting the message from the UE to a base station.

A method for mitigating interference in a frequency hopping channel system based on codeword metrics obtained during decoding of codewords. The method includes decoding a plurality of codewords using a particular error control coding method. Each of the plurality of codewords includes portions received from plurality of channels in the frequency hopping channel system. For each decoded codeword, one or more codeword metrics are obtained based on the cost of correcting errors during decoding of the plurality of codewords. Based on the codeword metrics, one or more channel metrics are inferred. Based on the inferred one or more channel metrics, a reliability metric of a particular channel is reduced, or incoming symbols received from the particular channel are ignored during decoding.

Aspects presented herein may enable a UE to determine whether phase continuity is to be maintained for one or more uplink transmissions when the UE is configured with a frequency-hopping with zero frequency offset. In one aspect, a UE receives, from a network entity, an indication of frequency hopping with zero frequency offset. The UE determines whether phase continuity is to be applied to UL transmissions based on the indication of the frequency hopping with zero frequency offset. The UE transmits, to the network entity, at least one uplink channel with no phase continuity based on the determination to not apply phase continuity to the UL transmissions.

Techniques providing opportunistic frequency switching for frame based equipment (FBE), such as may be configured to minimize opportunistic frequency switching delay in FBE new radio (NR) unlicensed (NR-U) networks and/or to provide frequency diversity FBE access based on offset sequences of medium sensing occasions for the carrier frequencies are disclosed. Within the FBE mode network, a base station may configure a pattern of sensing locations in each frame for each frequency transmission unit of the plurality of frequency transmission units, wherein an inter-unit delay of sensing locations between a first frequency transmission unit and a next adjacent frequency transmission unit and between a last frequency transmission unit and the first frequency transmission unit is a fixed duration. Opportunistic frequency switching of embodiments may utilize the medium sensing locations for opportunistically switching between a sequence of the frequency transmission units for implementing frequency diversity FBE access.

A wireless network with network-level channel hopping. A wireless network includes a wireless device. The wireless device includes a receiver, a data channel selector, and a transmitter. The receiver is configured to receive a beacon signal comprising a beacon sequence value. The data channel selector is configured to select, as a pseudorandom function of the beacon sequence value, a data channel on which to transmit in an interval following reception of the beacon signal.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for measurement without gaps for narrow bandwidth part (BWP) hopping. A user equipment (UE) may measure one or more synchronization signal blocks (SSBs) while performing BWP hopping according to a hopping pattern. The UE may receive data and measure an SSB in a same frequency hop during a same measurement window without a gap. A base station (BS) may transmit a control message to the UE to configure an active BWP for the UE, a set of measurement windows, a hopping pattern, and a set of SSBs that occur within a set of frequency hops to support the measurement without gaps. The active BWP may be defined for measurement purposes to reduce ambiguity. The control message may support alignment of a measurement window with an active frequency hop to support measurement without gaps.
