Problems solved by technology

For PUSCH based on dynamic scheduling, it is easier for the base station to allocate PUSCH resources reasonably, so that uplink data and / or uplink control information can be sent at an ideal modulation and coding rate. How to attach information to PUSCH and send it, there is no effective method
In addition, since the resources for GF uplink transmission are semi-statically configured, and the base station may not be able to determine whether the user terminal will send uplink data, it is difficult for the base station to adjust PUSCH resources according to the uplink control information and uplink data to be sent, and a guarantee is urgently needed Method for effective transmission of uplink data and uplink control information
Moreover, for GF uplink transmission, there is often no need for dynamic uplink scheduling signaling (UL grant), and the base station cannot indicate dynamic adjustment information related to uplink control information, such as the overhead of uplink control information. Therefore, a new mechanism is also needed to Ensure effective transmission of uplink control information

Embodiment 1

[0198] If time slot n is an uplink time slot configured by the base station for uplink transmission, and the user terminal has uplink data to be sent in time slot n, then the user terminal needs to determine whether there is an uplink data that may need to be sent in time slot n control information. If there is uplink control information, the user terminal judges according to predefined rules whether to send the PUSCH carrying uplink data on time slot n, and send all or part of the uplink control information on the PUSCH at the same time; or send only uplink data on time slot n data, but the PUSCH does not carry the uplink control information; or in time slot n, only the PUCCH carrying the uplink control information is sent, and the PUSCH for carrying at least the uplink data is not sent.

[0199] The PUSCH may be the PUSCH of the GF, or the PUSCH based on dynamic UL grant scheduling.

[0200] Sending PUSCH in time slot n may include at least one of the following two situatio...

Embodiment 2

[0302] If time slot n is an uplink time slot configured by the base station for GF uplink transmission, and the user terminal has uplink data to be sent in time slot n, then the user terminal needs to determine whether there is any data that may need to be sent in time slot n Uplink control information. If there is uplink control information, the user terminal judges according to the predefined rules whether to send the GF’s PUSCH to carry uplink data on time slot n, and send all or part of the uplink control information on the PUSCH at the same time; or send only PUSCH on time slot n Carrying uplink data without sending uplink control information; or sending only PUCCH to carry uplink control information on time slot n, without sending a PUSCH for carrying at least uplink data.

[0303] The predefined rule is to determine whether all or part of the control information can be sent on the PUSCH according to the predefined threshold and / or priority.

[0304] Among them, the pre...

Embodiment 3

[0330] Send ACK / NACK on the PUSCH of the GF. When the number of ACK / NACK bits exceeds the predefined threshold, rate matching needs to be performed on the PUSCH. In order to ensure that the base station side and the user side have the same understanding of the rate matching resources, it is necessary to make the user terminal and the base station side have a completely consistent understanding of the number of ACK / NACK bits.

[0331] Different from the scheduling-based PUSCH, the dynamic uplink scheduling signaling (UL grant) of the scheduling-based PUSCH can clearly indicate the number of ACK / NACK bits, while the GF’s PUSCH has no UL grant, so it can only pass the predefined rules and PDSCH The scheduling signaling determines the number of ACK / NACK bits.

[0332]An implementation manner is to limit the number of ACK / NACK bits sent on the PUSCH of the GF to always be an integer multiple of M. Correspondingly, if the base station finds that ACK / NACK may be sent on the PUSCH of...

Abstract

The invention provides an uplink control information processing method and a terminal. The uplink control information processing method comprises the following steps: determining uplink control information overlapped with a PUSCH resource in a time domain according to the PUSCH resource; And determining whether to send the uplink control information, and carrying out corresponding processing basedon a determination result. According to the invention, the uplink control information to be sent is effectively sent, and the sending efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method for processing uplink control information and a terminal. Background technique [0002] With the rapid development of the information industry, especially the growing demand from the mobile Internet and the Internet of Things (IoT, internet of things), unprecedented challenges have been brought to future mobile communication technologies. For example, according to the report ITU-R M.[IMT.BEYOND2020.TRAFFIC] of the International Telecommunication Union (ITU), it can be predicted that by 2020 (compared to the 4G era in 2010), the mobile service volume will increase nearly 1,000 times. The number of user terminal connections will also exceed 17 billion. As a large number of IoT devices gradually penetrate into the mobile communication network, the number of connected devices will become even more astonishing. [0003] To cope with this unprecedented ...
