Abstract: A transmitter is configured to set a counter to a starting value, sense whether a channel is busy or idle and to update the counter value during sensing. When there is data to be transmitted, the transmitter is configured to determine, based on at least the counter value at a transmit opportunity and a duration the channel has been sensed idle before the transmit opportunity, whether to transmit the data or to continue the sensing the channel to a next transmit opportunity without resetting the counter value to the starting value.

Abstract: Embodiments of the present disclosure relate to bit reduction in resource information. According to embodiments of the present disclosure, the number of bits to indicate the resource allocation is reduced and the network device generate the control information based on an offset associated with the bit reduction. In this way, multiple transmission opportunities for the transmission of Msg3 of the random access procedure are provided without increasing the signaling overhead.

Abstract: There are provided measures for handling of paging messages in communication endpoint to network relaying scenarios. Such measures exemplarily comprise, at a relay terminal connected to a mobile access entity of a cellular network systems, selecting, for a terminal to be relayed, a sidelink communication group of a set of configured sidelink communication groups, monitoring network-served paging indicator resources corresponding to said terminal to be relayed for a network-served paging related identifier indicative of transmission of a network-served paging message and information on network-served paging message resources for said transmission of said network-served paging message, transmitting, if said network-served paging related identifier indicative of transmission of said network-served paging message is detected in said network-served paging indicator resources corresponding to said terminal to be relayed and information indicative of paging of said terminal to be relayed is identified in said network-served paging message transmitted in said network-sewed paging message resources as a result of said monitoring, in inter-terminal paging indicator resources configured for said sidelink communication group and next to said network-served paging message resources including said information indicative of paging of said terminal to be relayed, an inter-terminal paging related identifier indicative of transmission of an inter-terminal paging message and information on inter-terminal paging message resources for said transmission of an said inter-terminal paging message, and transmitting said inter-terminal paging message in said inter-terminal paging message resources for said transmission of said inter-terminal paging message.

Abstract: Systems, methods, apparatuses, and computer program products for cyclic prefix (CP) extension and listen before talk (LBT) type for uplink transmissions. Specifically, certain embodiments may provide for applying a CP and/or an LBT when downlink control information (DCI) schedules two discontinuous uplink transmissions. For example, certain embodiments may provide for determining the LBT type and CP extension for jointly scheduled aperiodic sounding reference signal and physical uplink shared channel/physical uplink control channel transmissions. When the two or more transmissions are non-consecutive, the first one of the transmissions may apply the CP extension and the LBT type indicated by the scheduling DCI. For the second transmission, the CP extension may depend on the CP extension indicated in the DCI.

Abstract: A method may include determining an uplink loss metric for an uplink communication path from a user equipment to a base station in a wireless network based at least on an uplink transmit beam for the user equipment and an uplink receive beam for the base station; determining a downlink loss metric for the downlink communication path from the base station to the user equipment based at least on a downlink transmit beam for the base station and a downlink receive beam for the user equipment; and determining, based on the uplink loss metric and the downlink loss metric, an uplink/downlink beam correspondence misalignment for the user equipment that indicates that the uplink transmit beam for the user equipment is misaligned with the downlink receive beam for the user equipment. For example, see FIGS. 5-6.

CPC classification number: H04W74/0808 , H04W16/14
Abstract: A node configured to support a method of communicating between two nodes in the unlicensed spectrum is disclosed where a channel can be simultaneously used for downlink and uplink communication. The method performed at a node involves assessing at that node, for example, a UE, that there is a transmission to be made to a further node, for example a gNB. The first node receives an indication that communication with the further node is supportable on a channel within an unlicensed spectrum using flexible frequency division duplex (FDD) techniques. The first node determines whether transmission by the further node is being made within a first portion of the channel within the unlicensed spectrum; and if so, transmits to the further node within a second portion of the channel which does not overlap with the first.
