摘要： Systems and methods are disclosed in which the start time of a downlink transmission to a user equipment (UE) is more flexible. For example, instead of beginning at predetermined starting points in a frame or subframe, a downlink transmission may instead possibly begin every x OFDM symbols, where x may be as small as one OFDM symbol.

摘要： Resources used for downlink communication may be partitioned by the base station so that a portion of the resources is reserved for the downlink transmission of low latency data. However, low latency data may be bursty or sporadic in nature, and may be transmitted in short packets. Therefore, there may not always be low latency data at the base station that needs to be transmitted using all of the low latency resources. System and methods are therefore disclosed in which the base station opportunistically schedules, on the low latency resources, latency tolerant data for one or more latency tolerant UEs. When latency tolerant data is scheduled on the low latency resources, signaling is used to indicate if the latency tolerant transmission on the low latency resources is modified.

摘要： Feedback from a base station is used to reduce retransmissions of a grant-free UE where the SINR of an initial transmission from the grant-free UE is higher than a threshold. Feedback from a base station is also used to adjust transmission by grant-based UEs in resources that overlap with those also available to grant-free UEs.

摘要： In response to receiving a random access channel message from a User Equipment (UE), a network element in a communication network may initiate a random access procedure, for example. The random access channel message includes multiple sequences, such as a first sequence associated with a group of UEs that includes the UE and a second sequence associated with the UE, and may be in any one of multiple different message formats. The random access procedure could include respective search stages for each of the multiple sequences. Power control for random access message transmission is also implemented by the UE in some embodiments.

摘要： Systems and methods for reference signal transmission, such as demodulation reference symbol and CSI-RS. The network transmits a reference signal scrambling ID to the UE, and both the network and the UE use this to calculate an initialization sequence for the reference signal. The, one or the other of the network and the UE transmit the reference signal. Optionally, the reference signal is based on a UE-related ID, or a combination of the UE-related ID and one or more other fields.

摘要： Systems and methods are provided for configuring a bit length of a user equipment identifier (UE ID) used for communications in Layer 1 or Layer 2, or both, between a UE and a network. Multiple mechanisms are provided for the network to provide identifier parameter information (for example bit length and/or an identifier value or a range of values) to the UE to allow the UE to select a particular UE ID based on the identifier parameter information.

摘要： Methods and apparatus are provided for integrated communication and sensing. For example, an electronic device may transmit a radio frequency (RF) pulse signal in the active phase of a periodic sensing cycle, and sense in the passive phase of the sensing cycle, a reflection of the RF pulse signal reflected from an object. The RF pulse signal is defined by a waveform for carrying communication data between electronic devices. The sensed RF pulse signal is at least a portion of the transmitted or reflected RF pulse signal, wherein the portion is equal to or greater than a threshold value for the object being within a sensing range of the first electronic device. The electronic device may also receive a communication signal from another electronic device during the passive phase.
