Abstract:
A method comprises receiving in a first subframe of a burst from a base station a downlink transport block for which an acknowledgement is required. A first uplink channel in which an acknowledgement of said transport block to be provided is prepared. The first uplink channel is independent of transmission information. The first prepared uplink channel is transmitted with the acknowledgement in a later burst.
Abstract:
Various communication systems may benefit from improved uplink data transmission. A method may include determining an assignment, at a user equipment, of a first set of physical resource blocks in an unlicensed spectrum to a physical random access channel. The physical random access channel occupies at least one of the physical resource blocks, and wherein the at least one of the physical resource blocks occupied by the physical random channel are distributed into clusters in a frequency domain. The method may also include determining an assignment, when the user equipment transmits data, of a second set of at least one remaining physical resource block of the physical resource blocks to at least one uplink channel. In addition, the method can include transmitting random access preambles through the physical radio access channel or data through of the at least one the uplink channel from the user equipment to a network entity.
Abstract:
Various communication systems may benefit from appropriate scheduling and distribution of control systems. For example, wireless communication systems may benefit from usage of a physical uplink control channel for quasi-periodic control signals. A method can include configuring a quasi-periodic signal resource for a user equipment. The method can also include communicating with the user equipment in accordance with the configured quasi-periodic signal resource.
Abstract:
There is provided a method including receiving information at a user device capable of operating using carrier aggregation, said information including an indication of a first carrier and at least one second carrier to be used for a signalling procedure, causing transmission from the user device of a first signal of the signalling procedure using at least one of the first carrier and the at least one second carrier and monitoring the first carrier and the at least one second carrier for transmission of a second signal of the signalling procedure from an access point.
Abstract:
Systems, methods, apparatuses, and computer program products for a new radio (NR) physical layer arrangement are provided. One method may include receiving, by user equipment, configuration of scheduling request resources on a plurality of resource pools. The method may also include determining a slot type when the user equipment is to transmit a scheduling request in a certain slot, and, based on the determined slot type and the received scheduling request resources configuration, determining whether the user equipment has a scheduling request resource allocated in the plurality of resource pools in the certain slot.
Abstract:
A method comprising including receiving at a user equipment first power information for transmitting to a first base station, receiving at the user equipment second power information for transmitting to a second base station, causing said user equipment to transmit to said first base station with a first power less than or equal to a first maximum power dependent on said first power information and causing said user equipment to transmit to said second base station with a second power less than or equal to a second maximum power dependent on said second power information, such that said first and second power does not exceed a total power allowed for said user equipment
Abstract:
Apparatuses and methods for communication are provided. The solution includes receiving a message from a base station a user terminal is connected to. The message instructs the user terminal to search from a control channel transmitted by the base station an indicator. If the indicator is found, the user terminal operates according to a configuration where given downlink subframes are suspended. If the indicator is not found, the user terminal continues searching and assumes no change in downlink subframe transmission.
Abstract:
A method for network synchronization of a first network element is provided, comprising: receiving, from each of at least two synchronization candidate network elements, a first synchronization accuracy value; determining, for each of the at least two synchronization candidate network elements, a signal quality indicator; determining for each synchronization candidate network element a second synchronization accuracy value based on the signal quality indicator and the first synchronization accuracy value related to the synchronization candidate network element, and selecting a synchronizing network work element, for synchronizing the first network element to, from the at least two synchronization candidate network elements, based on the determined second synchronization accuracy values. The present disclosure enhances the performance of RIB network synchronization by indicating an estimate of an accumulated synchronization error magnitude. The indication is beneficial for RIB source network element or source cell selection and it could help to make the topology of synchronized network elements/cells more reasonable.
Abstract:
Two physical layer user terminal capability alternatives are introduced for device-to-device discovery for FDD mode terminals: a full discovery physical layer capability, and a partial discovery physical layer capability. The full discovery physical layer capability corresponds to an alternative where a discovery-capable user terminal has a capability to perform both Discovery_Scan (on an uplink band) and Discovery_Tx (on a downlink band) operations. A Discovery_Tx operation corresponds to transmission of a discovery signal to another user terminal directly over the air. A Discovery_Scan operation corresponds to reception of the discovery signal from another user terminal directly over the air. The partial discovery physical layer capability corresponds to an alternative where the discovery-capable terminal has a capability to perform either Discovery_Scan operation (on the downlink band) or Discovery_Tx (on the uplink band) operation (or both).
