  • Patent number: 11109237
    Abstract: A first wireless node of a wireless communication system is associated with a first cell having a first cell identity. The first wireless node obtains information relating to a set of wireless nodes which use at least one overlapping communication resource that is also used by at least one second node in the first cell. The first wireless node generates a preamble containing: a first data field designating the first cell identity, and a second data field reflecting a respective identity of the wireless nodes in the set of wireless nodes which use the at least one overlapping communication resource. The first wireless node transmits a preamble signal containing the preamble, over a predefined set of resources in a shared resource structure of the wireless communication system thus informing about the wireless nodes that use overlapping communication resources.

  • Publication number: 20210258822
    Abstract: Apparatus and methods for improving throughput and reliability in a wireless network. In one embodiment, the apparatus and methods provide mechanisms for wireless user device buffer management that mitigate buffer overflow within the device due to overscheduling, such as from different networks with which the device is connected simultaneously. In one variant, a 3GPP-based signaling architecture from wireless device to the multiple networks is provided to enable user device-controlled management buffer overflow. In another variant, potentially buffer-demanding (e.g., HARQ) process management and prioritization rules are defined to avoid buffer overflow. In other variant, buffer size computation is provided considering the number of networks to which the wireless user device can connect.

  • Publication number: 20210250828
    Abstract: According to one configuration, while the user equipment is wirelessly connected to a first wireless base station over a first wireless communication link, a communication management resource in the user equipment receives input (such as a request) to tune-away the user equipment to a second wireless base station providing corresponding wireless services. To facilitate the temporary tune-away to the second wireless network, the communication management resource of the user equipment generates timing information associated with the switchover. In furtherance of the switchover (temporary tune-away) to the second wireless base station, the communication management resource of the user equipment transmits the timing information in a wireless communication over the first wireless communication link to the first wireless base station.

  • Patent number: 11088779
    Abstract: Methods and apparatus for supporting transmission bursts in unlicensed spectrum are described. Different sets of sub-bands within a downlink bandwidth portion of unlicensed spectrum can be, and sometimes are, occupied during different DL transmission bursts depending on channel availability. A user device is configured with channel usage information, e.g. N bitmaps, each bitmap indicating a different control channel resource allocation that may be used for communication with the UE, and/or reference signal information. The UE determines the occupied sub-bands in a DL transmission burst over the bandwidth portion, and determines control channel resource information based on the determined occupied sub-channels. The UE determines CSI-RS measurement locations based on determined sub-band occupancy. In some embodiments, the UE performs in-sync and out-of-sync evaluations based BLER threshold scaling factors, which are based on sub-band occupancy.

  • Patent number: 11088785
    Abstract: Radio Link Control ACK/NACK is conditionally suppressed. A first wireless communications device including a radio transmitter identifies a first packet flow for which end to end packet retransmission is supported. The first wireless communications device identifies a Packet Data Convergence Protocol (PDCP) packet corresponding to Radio Link Control Acknowledged Mode (RLC AM), said identified packet being included in the identified first packet flow. The first wireless communications device generates an Acknowledged Mode Protocol Data Unit (AM PDU) including a No RLC ACK Required (NRAR) indicator set to indicate RLC ACK is not required, and the radio transmitter in the first wireless communications device transmits the AM PDU, e.g., an AMD PDU, to a second wireless communications device. The second wireless communications device receives the transmitted AM PDU, recovers the NRAR indicator value, and based on the communicated value of the NRAR indicator, determines to suppress RLC ACK/NACK.

  • Publication number: 20210243798
    Abstract: Embodiments herein relate to a method performed by a network node 110 of a wireless communication network 100 for communicating at an unlicensed frequency spectrum with a wireless device 121 having a device identity. The network node 110 sends an access grant to the wireless device according to the device identity, granting the wireless device access to an uplink communication channel of the unlicensed frequency spectrum. The network node also receives data from the wireless device 121, on the granted uplink communication channel, the data comprising information on the identity of the wireless device 121, thus enabling the network node 110 to detect whether the wireless device that was granted access on the uplink communication channel is the same wireless device as the wireless device from which the data comprising the information on the uplink communication channel was subsequently received. Embodiments of the network node 110 are also described.

  • Publication number: 20210243769
    Abstract: According to one configuration, a wireless network includes first wireless stations and second wireless stations. The first wireless stations and second wireless stations support different wireless communication protocols and compete to use a wireless channel. Via monitoring of a control channel generated by a management resource associated with at least the first wireless stations, a given wireless station of the second wireless stations determines availability (unused time slots, frames, etc.) of the wireless channel via monitoring of the wireless channel itself and/or a control channel. In the latter instance, the control channel indicates scheduled usage of the shared wireless channel by at least the first wireless stations. In accordance with the scheduled usage as indicated by the control channel, the given wireless station transmits over the wireless channel during free slots, times, gaps, etc., to communicate with a remote wireless station of the second wireless stations.

  • Patent number: 11057944
    Abstract: Systems and methods are disclosed that enable multi-cast transmissions (e.g., Physical Multi-cast Channel (PMCH) transmissions) on carriers in unlicensed spectrum. In some embodiments, a method of operation of a radio access node to enable multi-cast transmissions on a carrier in an unlicensed spectrum comprises performing a Listen-Before-Talk (LBT) procedure on a carrier in an unlicensed spectrum based on random backoff and a contention window size prior to a multi-cast transmission. The method further comprises transmitting the multi-cast transmission if the LBT procedure determines that the carrier in the unlicensed spectrum is Idle. In this manner, multi-cast transmissions on the carrier in the unlicensed spectrum are enabled.

  • Publication number: 20210176794
    Abstract: Apparatus and methods for multi-cell broadcast access channel utilization in a wireless network. In one embodiment, the apparatus and methods provide random access channel (RACH) procedure for a 3GPP-compliant user device (e.g., an enhanced UE or UEe) which attempts to connect to multiple cells simultaneously. In one variant, the UEe employs a multi-step (e.g., 4-step) RACH procedure to connect to the multiple cells. This significantly increases the likelihood of RACH procedure success and UEe access. In another variant, a 2-step RACH process is utilized. Variants of the apparatus and methods utilizing unlicensed spectrum and LBT (listen-before-talk) protocols are also described.
