METHOD AND DEVICE FOR WIRELESS COMMUNICATION IN NODES

TECHNICAL FIELD

This application relates to a transmission method and a device in a wireless communication system, in particular to a transmission scheme and a device for information with different priority levels in wireless communication.

BACKGROUND

The application scenarios for future wireless communication system are becoming increasingly diverse, with different scenarios having different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, it was decided at the 72nd plenary session of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) to conduct research on NR (New Radio) (or 5G). At the 75th plenary session of 3GPP RAN, the WI (Work Item) of NR (New Radio) was approved, after which the standardization work on NR was started. At the 86th plenary session of 3GPP RAN, it was decided to start work on the SI (Study Item) and WI (Work Item) of NR Rel-17.

In the NR technology domain, eMBB (enhanced Mobile Broadband), URLLC (Ultra-reliable and Low Latency Communications), and mMTC (massive Machine Type Communications) are the three main application scenarios.

SUMMARY

URLLC communication features transmission of data or control information with different priority levels. In NR Rel-16, when UCIs (Uplink Control Information) with different priority levels collide in the time domain, lower priority UCIs are discarded to ensure the transmission of higher priority UCIs. In NR Rel-17, it supports the reuse of UCIs with different priority levels onto the same physical uplink control channel (PUCCH).

This application discloses a solution for the reuse problem of UCIs associated with different priority levels. It should be noted that this application only describes URLLC as a typical application scenario or example. This application is also applicable to other scenarios facing similar problems (such as scenarios where a plurality of services coexist, or other scenarios where information with different priorities is reused, or scenarios where services are reused with different QoS requirements, or for different application scenarios, such as Internet of Vehicles and eMBB multiplexing). In these scenarios, a similar technical effect can be achieved. In addition, adopting a unified solution for different scenarios (including but not limited to URLLC scenarios) can also help reduce hardware complexity and costs. Without any conflict, the embodiments and features in the first node of this application can be applied to the second node, and vice versa. Specifically, for the interpretation of terminologies, names, functions, and variables in this application (if not otherwise specified), please refer to the definitions in the TS36 series, TS38 series and TS37 series of standard 3GPP protocols.

This application discloses a method for the first node in a wireless communication system, comprising:

- receiving a first signal, the first signal is used to determine a target resource group, which occupies the target time domain symbol group in the time domain, and the target time domain symbol group comprises at least one time domain symbol;
- sending a first PUCCH in the target resource group. The first bit sequence is used to generate the first PUCCH, and the first bit sequence comprises a plurality of bits in sequential order.

The first bit sequence comprises a first bit subset and a second bit subset. The first bit subset comprises at least one bit after encoding the first bit block, and the second bit subset comprises at least one bit after encoding the second bit block. The priority index value associated with the first bit block is equal to the first priority index value.

The number of target bits is equal to the number of bits comprised in the first bit subset, and the number of bits carried by the target resource group on at least one time domain symbol comprised in the target time domain symbol group is used together with the number of target bits to determine the target interval, which is a positive integer. The target interval is used to determine the distribution of bits comprised in the first bit subset in the first bit sequence.

As an embodiment, the distribution of bits comprised in the first bit subset in the first bit sequence is determined based on the target interval, thereby supporting interleaved multiplexing between high priority bits and low priority bits, achieving greater frequency diversity gain and time domain diversity gain, and improving the transmission performance of the UCI.

As an embodiment, the target interval is determined by combining the number of bits carried by the target resource group on at least one time domain symbol comprised in the target time domain symbol group with the value of the number of target bits. Therefore, while considering the frequency grading gain, the delay of high priority bits is also taken into account, which improves the high priority transmission performance while minimizing the transmission delay as much as possible.

According to an aspect of this application, the above method is characterized in that the target difference is equal to the difference between the target bit numerical value and the second numerical value, and the target interval is equal to the maximum integer not greater than the first ratio. The ratio of the first numerical value to the target difference is used to determine the first ratio.

As an embodiment, in the interleaved multiplexing of high priority bits and low priority bits, interleaved multiplexing only occurs on the latest time-domain symbol mapping the high priority bits, while obtaining frequency diversity gain and reducing the transmission and decoding delay of the high priority bits.

The ratio of the target sum value to the target bit numerical value is used to determine the second ratio.

As an embodiment, the number of RBs occupied is determined based on the encoding rates of high and low priority bits, which matches the allocated resources with the configured bit rate, thus improving resource utilization and transmission performance.

According to an aspect of this application, the above method is characterized in that the first modulation order is equal to the modulation order of the first PUCCH, the target resource group comprises a plurality of REs, and the second time domain symbol is a time domain symbol comprised in the target time domain symbol group. The first modulation order and the number of REs comprised in the target resource group on the second time domain symbol are used together to determine the number of bits carried by the target resource group on the second time domain symbol.
