Description

Method and device for transmitting uplink control information

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for transmitting uplink control information.

Background

In 5G, one slot is a scheduling unit, and one slot includes 7 or 14 symbols. And there are various slot types, wherein the slot types that can be used for transmitting uplink control (UL control) include the following:

DL domain type: the last 1-2 Orthogonal Frequency Division Multiplexing (OFDM) symbols in a time slot are uplink transmission resources, and the rest symbols are downlink transmission resources and gap;

UL domain type: the first 2-3 symbols in a time slot are downlink transmission resources and gap, and the rest symbols are uplink transmission resources;

UL only type: all symbols in a time slot are downlink transmission resources.

In the future 5G, the types of UL control include short duration (short duration) and long duration (long duration)2 types. Wherein the short duration supports 1-2 symbol lengths; the long duration supports a length of 4 symbols or more; therefore, the number of UL control symbols supported by the long duration in one slot is variable, and the number of symbols that can be supported may be any one of 4,5,6,7,8,9,10,11,12,13, and 14. In addition, in the future 5G, there are a plurality of different subcarrier widths, and the wider the subcarrier, the shorter the duration occupied by the symbol is, so if the PUCCH in length duration needs to reach the coverage (1ms) of LTE, the PUCCH in length duration needs to be supported for transmission in a plurality of slots.

In an existing Long Term Evolution (LTE) system, 2 Physical Resource Blocks (PRBs) at two ends of an Uplink slot band are generally utilized to transmit Physical Uplink Control information (PUCCH), and the PUCCH occupies 14 OFDM symbols in a time domain. In LTE, the uplink control channel has only one configuration, so scheduling is relatively simple, and the subframe for uplink control signal transmission is implicitly indicated.

However, in the future 5G, the symbol length of PUCCH is variable and transmission on multiple slots (slots) is supported, and if one structure is designed for each symbol length of PUCCH, there will be multiple PUCCH structures, which may result in increased complexity of implementation of PUCCH transmission, both for base station scheduling and UE implementation.

Mode a1, after the OFDM symbol for transmitting DMRS is transmitted, a specific format of PUCCH in long duration including M OFDM symbols (symbols) may be as shown in fig. 1A to 1K (fig. 1A to 1K respectively show formats of PUCCH with M symbols being 4 to 14), where M is an integer not less than 4 and not more than 14; mode a2, the specific structure of the OFDM symbol transmitting UCI before the OFDM symbol transmitting DMRS is similar to mode a1, except that the position of the OFDM symbol transmitting DMRS is adjusted to be after the OFDM symbol transmitting UCI.

In the method B, because the channel changes are severe sometimes, for example, greater than 6GHz, more than 2 symbols may be set for transmitting the DMRS in order to improve the reliable transmission of the reception performance guarantee signal, and then the position relationship between the OFDM symbol for transmitting the UCI and the OFDM symbol for transmitting the DMRS may be:

mode B1, the OFDM symbols transmitting UCI are between the OFDM symbols transmitting DMRS; mode B2, if the OFDM symbol transmitting DMRS is between the OFDM symbols transmitting UCI, the corresponding PUCCH format is similar to mode B1 except that the position of the OFDM symbol transmitting DMRS is adjusted between the OFDM symbols transmitting UCI.

In the above mode a and mode B, because the DMRS in the mode B needs to occupy two OFDM symbols, in order to balance the number of symbols of the DMRS and the UCI, in this embodiment, whether the mode a or the mode B is selected for UCI transmission may be determined according to the number of symbols of the PUCCH, and the specific implementation may be:

Optionally, the terminal device and the network device may transmit the positive integer Q through downlink control information DCI signaling or radio resource control RRC signaling or cell broadcast signaling or pre-configuration information.

In the embodiment corresponding to the mode B, when the specific format of the PUCCH including M OFDM symbols is as shown in fig. 2A to 2K, where M is an integer not less than 4 and not greater than 14; in a specific implementation, the first symbol may be used to transmit the DMRS, and then the DMRS may be transmitted every 2 symbols, and a symbol between two DMRSs may be used to transmit UCI. In addition, according to the position relationship between the OFDM symbol occupied by the DMRS and the OFDM symbol occupied by the UCI disclosed in the mode B, the format of the PUCCH may include multiple formats, and examples given in fig. 2A to fig. 2K are only one of the schemes in the embodiment of the present application, and do not limit that the scheme provided in the embodiment of the present application can only be implemented by this mode.

Further, after the PUCCH with the specific format is generated based on the above manner, the UCI may be transmitted on the PUCCH by the following method, and specifically, the UCI may be transmitted on the PUCCH by occupying at least one slot.

For example, if one UE needs to transmit PUCCH including 14 OFDM symbols on 2 slots, PUCCH including 4 OFDM symbols may be transmitted on the first slot, PUCCH including 10 symbols may be transmitted on the second slot, which are 14 symbols in sum, and if the subcarrier bandwidth is 15kHz, 1ms coverage of LTE may be satisfied;

through the above manner, the UE may transmit the PUCCH with 4 OFDM symbols in the first slot and transmit the PUCCH with 10 OFDM symbols in the second slot according to the above scalable structure, where the two slots may be continuous or discontinuous, and specifically, each slot may use one of the PUCCH patterns as described in the first embodiment. The specific transmission implementation scheme may be:

scheme 1: the UCI transmitted in each slot is repeated, and is transmitted according to 144 (or 288) bits that can be supported by the maximum number of symbols (14 symbols), so that 4 symbols of PUCCH need to occupy 6 PRB transmissions in the frequency domain, and so on for PUCCH with other symbol lengths; the calculation formula is that if the number of symbols is X, the number of PRBs required to be occupied is rounded up from [ (14-2)/(X-2) ], and less than 1 PRB is transmitted according to 1 PRB and needs redundant coding;

scheme 2: UCI coding modulation needing to be transmitted on a plurality of slots generates a UCI, and then the modulated UCI is placed in a plurality of symbols used for transmitting the UCI on the plurality of slots to be transmitted according to the number of the symbols required to be placed in each slot.

The content described in the embodiment of the present application is that UCI is transmitted in PUCCH, and when the content is specifically applied, UCI is transmitted according to the method provided in the embodiment of the present application when the content is lower than the terminal device; the network device receives the UCI by the method provided by the embodiment of the present application.

By the method, the PUCCH formats with any length can be generated through one basic PUCCH format, the extensible structure is convenient for a receiving end and a transmitting end to realize, and the realization complexity of transmitting the PUCCHs with different lengths is reduced.

By the adoption of the extensible PUCCH format provided by the embodiment, the UCI can be conveniently transmitted on a plurality of slots.

The content described in the embodiment of the present application is that UCI is transmitted on PUCCH, and when the content is specifically applied, UCI is transmitted to the terminal device according to the method provided in the embodiment of the present application; the network device receives the UCI by the method provided by the embodiment of the present application.

In this embodiment, the terminal device and the network device may transmit the P through downlink control information DCI signaling or radio resource control RRC signaling or cell broadcast signaling or pre-configuration information.

The same as the method provided in the embodiment, in this embodiment, the UCI may also be transmitted on at least one slot occupied on the PUCCH, which facilitates transmission of UCI on multiple slots.

In the method provided in the foregoing embodiment, after the PUCCH is divided into two parts, the two parts may be located at different frequencies, but specifically when UCI is transmitted on the PUCCH, the OFDM symbols corresponding to the first part and the second part of transmission may be arranged at intervals in the time domain; for example, the first part is located at frequency F1, the second part is located at frequency F2, and the PUCCH on the first symbol is located at frequency F1; PUCCH on the second symbol is located at frequency F2; PUCCH on the third symbol is again located at frequency F1; the other symbols are placed sequentially according to the rule, as shown in fig. 5L.

Fig. 5L is an example of a PUCCH with 4 OFDM symbols, and PUCCHs with other symbol numbers may be obtained according to the same rule according to the embodiment shown in fig. 5L, and are not described herein again. In addition, since the frequency hopping scheme of the embodiment shown in fig. 5 does not affect the content format of the symbols in the PUCCH, various PUCCH formats in the first embodiment or the second embodiment may transmit UCI on the PUCCH by using the embodiment shown in fig. 5L.

By the method, two parts of the PUCCH format with any length can be generated through two parts of the basic PUCCH format, the extensible structure is convenient for a receiving end and a transmitting end to realize, and the realization complexity of transmitting the PUCCH with different lengths is reduced. Meanwhile, the embodiment supports various frequency hopping structures in the time slot, and can improve the receiving performance of the UCI transmitted on the PUCCH by using frequency diversity gain.

EXAMPLE III

With reference to the methods described in the first and second embodiments, the method provided in the embodiments of the present application may further support multi-user multiplexing when transmitting the PUCCH in the first and second embodiments, and the specific implementation manner may be:

mode one, support 1 ~ 2 bit UCI transmission (small payload size)

D1, modulating PUCCH to be transmitted into a Quadrature Phase Shift Keying (QPSK) symbol (which may also be modulated into symbols of other formats according to a specific implementation environment, the QPSK in this embodiment is merely for illustration and is not limited to use only this format), and repeatedly placing the modulated QPSK symbol on each of 12 subcarriers for transmitting PUCCH;

d2, when it is determined that multi-user multiplexing is to be supported, the QPSK symbols on the 12 subcarriers of each user are multiplied by a cyclic shift sequence, and the cyclic shift sequences used by each user are different and are orthogonal. Thus, the data of 12 users are superposed on the 12 subcarriers for simultaneous transmission, mutual interference is avoided, and the base station can normally demodulate and decode, thereby realizing multi-user multiplexing;

in a specific example, on 1 PRB, the PUCCH supports multiplexing of 12 users (as shown in fig. 6A); considering the adjacent cell interference, all 12 cyclic shift sequences may not be used in the frequency domain, for example, only 6 cyclic shift sequences are used, and at most 6 user multiplexes are supported.

D3, if it needs to support more user multiplexing, it needs to occupy more PRB number; or, the frequency hopping structure in the timeslot is not supported, and an orthogonal sequence may be used in the time domain, so that two groups of users multiplex resources, specifically, after 12 users are multiplexed in the frequency domain in step D1 and step D2, multiplexing of two groups of users in the frequency domain may be implemented in the time domain by using the orthogonal sequence in the time domain (as shown in fig. 6B), and each group of 12 users may increase the number of multiplexing users to 2 × 12 — 24.

In the second mode, based on the description of the first mode, the method provided in this embodiment may further support 3-24 (or 48) -bit UCI transmission (medium payload size)

In this specific example, the PUCCH occupies 1 PRB, and the PUCCH to be transmitted is modulated into QPSK symbols, and a total of 12 QPSK symbols are respectively placed on 12 subcarriers in 1 PRB. If the frequency hopping structure in the time slot is supported, the frequency hopping mode in the second embodiment is supported, QPSK modulation symbols transmitted on UCI located at different frequencies are repeated, and in this case, the embodiment does not support multi-user multiplexing; if multi-user multiplexing needs to be supported, multiple PRBs may be used to perform spreading in the frequency domain, for example, 2 PRBs support 2-user multiplexing, as shown in fig. 7A; if the frequency hopping structure in the slot is not supported, two parts of the PUCCH transmitted in the second embodiment are different, where UCI transmitted in the first part and UCI transmitted in the second part are different, so that a maximum of 48 bits can be supported, as shown in fig. 7B; or multiplexing 2 users using orthogonal sequences in the time domain, but only supporting 24-bit transmission.

Mode three, support more than 24 (or 48) bit UCI transmission (large payload size)

Based on the description of the mode one, in this embodiment, (as shown in fig. 8A and 8B, taking PUCCH with a length of 4 symbols as an example), PUCCH occupies 1 PRB, and modulates PUCCH to be transmitted into QPSK symbols, where the QPSK symbols are greater than 12, and the modulated QPSK symbols are respectively placed on each subcarrier of each symbol according to a placement principle of first frequency domain and then time domain, or first time domain and then frequency domain;

if a frequency hopping structure in a slot is supported, QPSK modulation symbols transmitted on UCI located at different frequencies are repeated, so that 1 PRB can be used for a PUCCH with 14 symbols, which can support 12 × 6 × 2 — 144 bits at most; if the hopping structure in the slot is not supported, when 1 PRB exists, the PUCCH with 14 symbols can support at most 12 × 6 × 2 ═ 288 bits;

if the mode needs to support multi-user multiplexing, the supported bit number can be reduced, for example, only 6 PRBs are transmitted in the frequency domain, and the other 6 PRBs are repeated, so that cyclic shift is adopted in the frequency domain, and at most 2 user multiplexing can be supported, and at most 144 bits are supported; or orthogonal sequences are adopted in the time domain, 144 bits are supported, and at most 2 user multiplexing can be supported.

By the method, the PUCCH format with any length in the first embodiment and the second embodiment can use the method, and multi-user multiplexing is supported, so that system transmission efficiency is improved, transmission from 1 bit to hundreds of bits can be supported, and the method can be applied to UCI transmission in various scenes.
