Abstract: The present disclosure relates to a client device and a network access node for transmitting and receiving a random access preamble which comprises a division of a set of resource blocks available for transmission of the random access preamble into at least two subsets of resource blocks, wherein each resource block in the set of resource blocks comprises a plurality of subcarriers, a first selection of resource blocks within the first subset of resource blocks and a second selection of resource blocks within the second subset of resource blocks, wherein the first selection of resource blocks is different to the second selection of resource blocks, and a mapping of a modulation sequence of the random access preamble onto at least one subcarrier in each selected resource block. Thereby, lower side-lobes of the auto-correlation function is achieved. Furthermore, the present disclosure also relates to corresponding methods and a computer program.

Abstract: Embodiments of this application provide a video service processing method. The method includes: a first device receives a plurality of data blocks of a first video service that are sent by a server based on a plurality of uplink request messages from a client; and determines a quantity of data blocks received between a first group of uplink request messages and a second group of uplink request messages that is adjacent to the first group of uplink request messages in the at least two groups of uplink request messages; and if one data block is received between the first group of uplink request messages and the second group of uplink request messages, and determines the data block received between the first group of uplink request messages and the second group of uplink request messages as an audio/video slice.

Abstract: A client device for wireless communication has a transceiver, and a processor. The transceiver receives frequency resource information to indicate a set of frequency resources for a PRACH preamble transmission. The frequency resource information indicates each frequency resource having: interlace information of B-IFDM allocation, resource element allocation information indicating a subset of resource elements within each block of the B-IFDM interlace, and resource element spacing information, such that a resource element within a block of the B-IFDM interlace is allocated for the transmission of one PRACH preamble according to a T-IFDM allocation. The resource element allocation is repeated in each block of the B-IFDM interlace. The processor is configured to select a frequency resource based on the received frequency resource information, and generate a PRACH preamble to be transmitted on the selected frequency resource. The transceiver transmits the generated PRACH preamble on the selected frequency resource.

Abstract: A client device includes a processor and a memory. The client device is caused to obtain a first indication indicating an outcome of a link monitoring procedure associated with a serving link between a network access node and the client device. The client device is also caused to obtain a second indication indicating an outcome of a link re-configuration procedure associated with the serving link. The client device is further caused to determine a value of a first counter associated with a radio link failure timer based on the first indication and the second indication. The client device is additionally caused to start the radio link failure timer when the value of the first counter is equal to or larger than a first counter threshold value.

Abstract: The present disclosure relates to reference signal design methods and devices. In one example method, a first communication device obtains at least one sequence from a subset of sequences in a set of sequences and obtains at least one reference signal based on the obtained at least one sequence. The sequence is phase rotated during its generation, phase rotated in the frequency domain, or cyclically shifted in the time domain based on a constant value Δq. The first communication device transmits the reference signal to a second communication device.

Abstract: The invention relates to a client device (100) and a network access node (300) for transmitting and receiving a random access preamble. The modulation sequence for the random access preamble is based on a first sequence and a second sequence. The first sequence is a sequence from a set of near-orthogonal sequences and the second sequence is a sequence from a set of constant envelope sequences. Due to its construction, the random access preamble herein provides low PAPR and suppresses the side-lobes in its auto-correlation function while producing a set of preambles with low cross-correlation. Furthermore, the invention also relates to corresponding methods and a computer program.

Abstract: Example wireless communications methods and apparatus with two-way beam failure recovery are disclosed. One example method includes receiving a downlink beam failure recovery request by a network device from a client device indicating at least one new downlink candidate beam determined to replace at least one failed downlink beam. The network device detects at least one failed uplink beam, determines at least one new uplink candidate beam to replace the detected at least one failed uplink beam, and generates uplink redirection information indicating the determined at least one new uplink candidate beam. A response including the generated uplink redirection information is generated by the network device, and transmitted to the client device.

Abstract: A network node for a wireless communication system includes a processor and a transceiver, the processor being configured to generate a set of at least two synchronization signal sequences; construct a synchronization signal for each synchronization signal sequence to create a set of synchronization signals, such that each of the synchronization signals in the set of synchronization signals has an auto correlation and cross correlation below a threshold value with any other synchronization signal in the set of synchronization signals; generate a set of directional beam patterns, wherein each beam pattern in the set of directional beam patterns corresponds to one of the synchronization signals in the set of synchronization signals; and wherein the transceiver is configured to transmit the synchronization signals in the set of synchronization signals using the beam pattern for each synchronization signal over a same time frequency resource.

Abstract: A first communication device determines a DMRS sequence based on a cover code in a set of cover codes; and thereafter determines a DMRS by mapping the DMRS sequence onto one or more PRBs. The cover code is dependent on a DMRS antenna port index, and cover codes in the set of cover codes are orthogonal to each other in each PRB, and wherein a maximum correlation power between two cover codes in the set of cover codes is larger than 0 in each half PRB. Finally, the first communication device transmits the DMRS via a DMRS antenna port having DMRS antenna port index to a second communication device which receive the DMRS and associated data signal. The second communication device demodulates the associated data signal based on the received DMRS and the DMRS sequence.

Abstract: An antenna port configuration method and apparatus are provided. The method includes: obtaining, by an access network device, M reference signal received power RSRP differences, where the M RSRP differences indicate radio signal strengths of N radio remote units RRUs, and both M and N are positive integers greater than 1; determining, by the access network device based on the M RSRP differences, an order of traversing the N RRUs; and for any RRU of the N RRUs, configuring, by the access network device, same antenna ports for two RRUs in the traversal order that are adjacent to the RRU, and configuring different antenna ports for the RRU and the RRUs adjacent to the RRU.
