DETAILED DESCRIPTION

The solutions in the embodiments of the present application are clearly and completely described below in combination with the accompanying drawings of the embodiments of the present application. The described embodiments are a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of the protection of the present application.

At present, in a new radio (NR) communication system, for the same terminal, in order to avoid higher peak to average power ratio (PAPR), a simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission is not supported. In case that time domain resources for PUCCH transmission and PUSCH transmission overlap, the terminal may perform multiplexing or perform selective transmission based on channel priority.

In case that resources for single slot PUCCH and PUSCH with the same physical layer priority overlap in one or more slots, for the single slot PUSCH or PUSCH repetition Type-A, the terminal multiplexes uplink control information (UCI) carried on the PUCCH in transmissions of all PUSCHs that overlap with the PUCCH; or for PUSCH repetition Type-B, the terminal multiplexes the UCI carried on the PUCCH in the first actual PUSCH that overlaps with the PUCCH and has more than one symbols.

In case that resources for multi-slot PUCCH and PUSCH with the same physical layer priority overlap, the PUSCH is dropped in a contention slot and only the multi-slot PUCCH is transmitted in the contention slot.

In case that resources for PUCCH and PUSCH with different physical layer priorities overlap in one or more slots, a channel having a lower priority is dropped and only a channel having a higher priority is transmitted.

At present, both hybrid automatic repeat request acknowledge (HARQ-ACK) and channel state information (CSI) carried on PUCCH may be transmitted through a PUSCH. In case that the number of HARQ-ACK bits is less than or equal to 2, the HARQ-ACK is transmitted by puncturing the PUSCH; or in case that the number of HARQ-ACK bits is greater than 2, the HARQ-ACK is transmitted by rate matching the PUSCH. The CSI is transmitted by rate matching the PUSCH. Both the HARQ-ACK and CSI are mapped to all layers of the transport block (TB) on the PUSCH for transmission.

The HARQ-ACK mapping starts from a first non-demodulation reference signal (DMRS) symbol after a first DMRS on PUSCH. In case that the number of HARQ-ACK bits is less than or equal to 2, a part of resources is reserved. In case that the number of HARQ-ACK bits is 0, 1 or 2, an HARQ-ACK resource is always reserved according to 2 bits. In case that an actual number of HARQ-ACK bit is 1, the HARQ-ACK is mapped to part resource of the reserved resource.

The CSI mapping starts from a first non-DMRS symbol on PUSCH. In case that the number of HARQ-ACK information bits is less than 2, a reserved resource for HARQ-ACK is on the PUSCH, and CSI part 1 is not mapped to the reserved resource, while CSI part 2 may be mapped to the reserved resource. In case that the number of HARQ-ACK information bits is greater than 2, PUSCH is rate-matched for transmission, and neither CSI part 1 nor CSI part 2 is mapped to the HARQ-ACK resource.

UCI frequency domain discrete mapping is performed within a transmission bandwidth of PUSCH in an order of frequency domain first and then time sequence. For a certain type of UCI, an interval d between modulation symbols in an orthogonal frequency division multiplexing (OFDM) symbol is determined as follows. In case that the number of remaining unmapped modulation symbols for the UCI is greater than or equal to the number of available resource elements (RE) in the OFDM symbol, d=1; otherwise, d=floor, where floor is a quotient obtained by dividing the number of available REs in the OFDM symbol by the number of remaining unmapped modulation symbols for the UCI.

However, at present, for a PUSCH transmitting one TB over multiple slots, there is no a UCI multiplexing method on the PUSCH.

Embodiments of the present application provide UCI multiplexing methods and apparatuses, and a storage medium, which may be used for UCI multiplexing on a PUSCH carrying multi-slot TB.

The methods and the apparatuses are based on the same conception. Since the principles of the methods and the apparatuses to solve the problems are similar, the implementation of the apparatuses and methods may be referred to each other, and the similar part is not repeated.

The solutions according to the embodiments of the present application may be applicable to various systems, for example, 5G systems. For example, the applicable systems may be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, etc. These various systems include a terminal device and a network device, and may further include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), and the like.

The terminal device in the embodiments of the present application may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the names of the terminal device may be different. For example, in the 5G system, the terminal device may be called as a user equipment (UE). A wireless terminal device may communicate with one or more core networks (CN) via a radio access network (RAN), and the wireless terminal device may be a mobile terminal device, such as a mobile phone (or cellular phone) and a computer with mobile terminal device, e.g., a portable mobile device, a pocket-sized mobile device, a handheld mobile device, a computer-built mobile device or a vehicle-mounted mobile device, which exchange language and/or data with the radio access network. For example, a personal communication service (PCS) phone, a radio phone, a session initiated protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) and other devices. A wireless terminal device may also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile platform, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or a user device, which is not limited in the embodiments of the present application. Since the terminal device and other network devices (such as a core network device, an access network device (e.g. a base station)) together form a network supporting communication, the terminal device may be regarded as a network device in the present application.

The network device in the embodiments of the present application may be a base station, and the base station may include multiple cells providing services for the terminal. Depending on the specific scenario, the base station may be called an access point, or a device communicating with a wireless terminal device through one or more sectors on the air interface in the access network, or other names. The network device may be used for exchanging received air frames with internet protocol (IP) packets, and acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an IP communication network. The network device may also coordinate attribute management for the air interface. For example, the network device in the embodiments of the present application may be a base transceiver station (BTS) in a global system for mobile communications (GSM) or a code division multiple access (CDMA), or may be a node B in a wide-band code division multiple access (WCDMA), or may be an evolutional node B (eNB or e-Node B) in a long term evolution (LTE) system, or may be a 5G gNB in 5G network architecture (next generation system), or may be a home evolved node B (HeNB), a relay node, a femto, or a pico, etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may be geographically separated.

In addition, it should be noted that the term “an embodiment” or “one embodiment” mentioned throughout the description means that a particular feature, structure or characteristic related to the embodiment is included in at least one embodiment of the present application. Therefore, the phrases “in an embodiment” or “in one embodiment” appearing throughout the description do not necessarily refer to the same embodiment. Furthermore, these specific features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

The following is a detailed illustration for the present application.

In the present application, UCI multiplexing refers to that UCI is multiplexed on PUSCH carrying multi-slot TB.

The PUSCH carrying multi-slot TB is that one TB is encoded based on the total number of symbols corresponding to PUSCHs in multiple slots, and encoded information is scattered across the multiple slots and transmitted through the corresponding PUSCHs.

FIG. 1 is a schematic flowchart showing steps of a UCI multiplexing method applied to a terminal according to an embodiment of the present application.

For a PUSCH carrying a multi-slot TB, in case that the PUSCH and a PUCCH overlap in at least one slot, the UCI multiplexing method includes the following steps:

• • step 101, determining resources required for UCI multiplexing on the PUSCH and an upper limit of resources used for UCI multiplexing on the PUSCH.

In the step 101, before the UCI multiplexing, the terminal needs to first determine the resources required for UCI multiplexing on the PUSCH, and determine a maximum resource, i.e. the upper limit of resources, that may be used for UCI multiplexing on the PUSCH.

Step 102: determining resources used for actual UCI transmission based on the resources required for UCI multiplexing on the PUSCH and the upper limit of resources used for UCI multiplexing on the PUSCH.

Since the upper limit of resources used for UCI multiplexing on the PUSCH does not necessarily meet the resources required for UCI multiplexing on the PUSCH, it is necessary to determine the resources used for actual UCI transmission based on the resources required for UCI multiplexing on the PUSCH and the upper limit of resources used for UCI multiplexing on the PUSCH.

In an embodiment, in the step 102, a smaller of the resources required for UCI multiplexing on the PUSCH and the upper limit of resources used for UCI multiplexing on the PUSCH may be determined to be the resources used for actual UCI transmission, to ensure a validity of the resources used for actual UCI transmission.

Step 103: transmitting the UCI on the PUSCH based on the resources used for the actual UCI transmission.

After the resources used for actual UCI transmission are determined, the UCI may be transmitted on the PUSCH based on the resources used for the actual UCI transmission. As such, for a PUSCH transmitting one TB over multiple slots, UCI multiplexing is supported on such multi-slot PUSCH, ensuring transmission performances of UCI and multi-slot PUSCH.
