摘要： A fifth-generation wireless communications network includes a server node, radio network equipment and a wireless device. In an example method, a server node receives first user data in response to (i) the wireless device receiving from the radio network equipment information indicating a plurality of uplink access configurations, each uplink access configuration including a random access configuration; (ii) the wireless device receiving an uplink access configuration index; (iii) the wireless device using the uplink access configuration index to identify an uplink access configuration from among the indicated plurality of uplink access configurations, and (iv) the wireless device transmitting the first user data to the wireless communications network according to the identified uplink access configuration. In the example method, further, the server node initiates transmission of second and third user data. This causes the wireless device to (v) receive from the radio network equipment, in a first downlink subframe, a first OFDM transmission formatted according to a first numerology and carrying the second user data, and (vi) receive from the radio network equipment, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology and carrying the third user data, wherein the numerologies have different subcarrier spacings.

摘要： A method performed by a communication node for transmission of a signal according to a single- or multiple carrier modulation scheme in a wireless communications network. The communication node modulates at least a first part of the signal into at least a first symbol with a shorter duration than a complete symbol according to the modulation scheme. The communication node modulates at least a second part of the signal into at least a second symbol with a shorter duration than a complete symbol according to the modulation scheme. The duration of the at least first and second symbols are equal to the duration of a complete symbol according to the carrier modulation scheme. Then, the communication node transmits the at least first and second symbol as a complete symbol according to the modulation scheme without time domain separation.

摘要： A communications network (10) comprises a base station (28) and a wireless terminal (30) which communicates over an air interface (32) with the base station (28). The base station (28) makes an identification or categorization of the wireless terminal (30) during a ranging procedure. The identification or categorization concerns whether or not the wireless terminal (30) has an enhanced capability. The categorization is made on a basis of a transmission characteristic of the wireless terminal (30). The base station (28) can then communicate with the wireless terminal (30) in a manner to utilize the enhanced capability of the wireless terminal (30).

摘要： Methods, apparatuses, and computer program products provide for routing information between nodes of a radio network. A quality metric is received at a network node that indicates a quality of at least one channel of a plurality of channels in the network. A virtual network is generated that includes one or more routes between a source node and a destination node. A modified virtual network is generated based at least in part on the quality metric and the virtual network, and is then used to determine an optimized route between the source node and destination node. The determination includes a joint selection of one or more of a plurality of network nodes and the plurality of the channels.

摘要： Systems and methods related to distributed route determination through a multi-hop wireless network based on multiple route metrics or properties are disclosed. In some embodiments, a method of operation of a network node comprises identifying a subset of neighbors of the network node in a wireless network based on: (a) link weight(s) for links from the network node to at least some of the neighbors of the network node with respect to route metric(s) and (b) defined limit(s) for the route metric(s). The method further comprises obtaining second link weights for the links from the network node to at least the subset of the neighbors with respect to a second route metric, and identifying from the subset of the neighbors, an optimal next hop neighbor for the network node. In this manner, multiple route metrics are taken into consideration in manner that is computationally efficient.
