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 radio network node for determining a partitioning of a first signal into one or more parts to be transmitted to a first radio node. The radio network node comprises two or more antennas, each associated with a respective radio chain. The radio network node and the radio node operate in a wireless communications network. The radio network node determines a number of radio chains, to be used to send the first signal, and determines a partitioning of the first signal into the one or more parts of the first signal over the determined number of radio chains. The one or more parts are to be transmitted to the first radio node. The radio network node determines the number of radio chains and the partitioning based on a scheduling decision associated with the radio network node, and one or more parameters.

摘要： A signal is received containing a block of multiple symbols, each symbol containing information bits spread by a spreading sequence of chips. Each spreading sequence is determined by a channelization sequence and a first or second complex- valued scrambling sequence of chips. Each block is processed using a set of spreading sequences using correlations between pairs of spreading sequences in the set. Spreading sequence correlation values between each pair are manipulated and stored in lookup tables. A lookup table address is determined using a first set of reduced basic scrambling bits to retrieve correlation values. The first set of reduced basic scrambling bits is based on manipulation of one set of the basic scrambling bits that reduces a number of bits included in the determined address to less than a number of binary values in the one set of basic scrambling bits. The one set of basic scrambling bits is used to construct one of the first and second complex-valued scrambling sequences. The retrieved correlation values may be used in mitigating spreading sequence correlation interference between spreading sequences in the set.
