Description

Method, equipment and system for transmitting uplink control signaling
Technical Field
The present disclosure relates to the field of wireless communications, and in particular, to a method, an apparatus, and a system for transmitting uplink control signaling.
Background
Compared to LTE (Long Term Evolution ), 5G NR (New Radio) will employ a higher frequency band, such as 3.5GHz, even greater than 6GHz. The NR uplink coverage with high frequency deployment is far worse than that of LTE with low frequency deployment. For this purpose, a less frequent supplemental uplink (Supplementary Uplink, SUL) carrier is introduced to improve NR uplink coverage.
In the related art, the base station transmits on an Uplink (UL) carrier or a SUL carrier through higher layer signaling, such as RRC (Radio Resource Control ) signaling, semi-statically configuring PUCCH (Physical Uplink Control Channel ). In addition, the base station schedules PUSCH (Physical Uplink Shared Channel ) for transmission on UL carrier or SUL carrier by PDCCH (Physical Downlink Control Channel ) signaling.
Disclosure of Invention
The inventor discovers that when the carrier signal of the PUCCH is poor or the transmission congestion occurs, the time delay of switching the transmission carrier of the PUCCH information to other carriers is large, which requires about hundreds of ms, and the normal transmission of the uplink control signaling can be influenced by semi-static configuration of the transmission carrier of the PUCCH through the high-layer signaling.
Furthermore, the inventors have found that PUCCH and PUSCH are transmitted separately, and in some cases UCI (Uplink Control Indicator, uplink control indication) signaling is transmitted over a PUSCH bearer, which may affect successful demodulation of UCI to some extent because PUSCH is a shared channel.
In view of this, on the one hand, the embodiment of the disclosure dynamically configures the transmission carrier of the PUCCH through the physical layer signaling, so that when the carrier signal where the PUCCH is located becomes worse or congestion is sent, the transmission carrier of the PUCCH information can be quickly switched to other carriers, the switching time delay is shortened to a few ms, and the influence on the uplink control signaling transmission is reduced. On the other hand, according to the embodiment of the disclosure, by simultaneously transmitting the PUCCH information and the PUSCH information, UCI signaling is transmitted through a PUCCH bearer, and the PUCCH is a special control channel, so that successful demodulation of UCI is facilitated.

Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
Fig. 1 is a flowchart illustrating some embodiments of a transmission method of uplink control signaling in the present disclosure. As shown in fig. 1, the method of this embodiment includes:
in step 11, the base station transmits PDCCH information, which includes a transmission carrier indicating PUCCH information, for example, an UL carrier or a SUL carrier.
In some embodiments, the transmission carrier of the PUCCH information is indicated by a PDCCH implicit method.
For example, the transmission carrier of the PUCCH information is indicated by identification information of a control resource set (control resource set, CORESET) representing the resources occupied by the PDCCH.
CORESET refers to the resource occupied by PDCCH, and the base station may configure multiple CORESETs for 1 user, each CORESET configured with an ID. The UE can know whether the carrier transmitting the PUCCH information is the UL carrier or the SUL carrier through the CORESET ID.
For another example, the transmission carrier of the PUCCH information is indicated by identification information of a search space (search space) of the PDCCH.
The search space refers to a search space where users blindly detect the PDCCH, and the base station may configure multiple search spaces for 1 user, each search space configured with one ID. The UE can know whether the carrier transmitting the PUCCH information is the UL carrier or the SUL carrier through the search space ID.
In some embodiments, the transmission carrier of the PUCCH information is indicated by a PDCCH explicit method.
For example, the transmission carrier of PUCCH information is indicated as UL carrier or SUL carrier by a field added by PDCCH, e.g., 1 bit.
For another example, the transmission carrier of the PUCCH information is indicated by PUCCH Resource Indicator (PRI, PUCCH resource indication) information, which is an UL carrier or a SUL carrier. That is, the indication information of the transmission carrier of the PUCCH information is encoded in association with the PRI information.
In some embodiments, when a carrier signal where PUCCH information is located is degraded or congestion occurs, a base station dynamically indicates, through PDCCH information, that a transmission carrier of PUCCH information is quickly switched to another carrier, and compared with an indication switching method of higher layer signaling (such as RRC), the indication switching method of physical layer signaling can shorten a switching delay, reduce several hundred ms to several ms, and reduce an influence on uplink control signaling transmission.
For example, when the user is located at the edge of the 5G cell, the UL carrier signal where the PUCCH information is located is degraded or congestion occurs, and the base station dynamically indicates, through the PDCCH information, that the transmission carrier of the PUCCH information is rapidly switched to the SUL carrier. When the user leaves the cell edge and moves to the middle area of the cell, the UL carrier signal is good, and the base station dynamically indicates the transmission carrier of the PUCCH information to be quickly switched back to the UL carrier through the PDCCH information.
Step 12, the ue receives the PDCCH information sent by the base station, and transmits PUCCH information on the carrier indicated by the PDCCH information.
The PUCCH information includes, for example, uplink control signaling such as UCI signaling, that is, UCI signaling is sent through a dedicated control channel PUCCH bearer, which is beneficial to successful demodulation of UCI, compared to UCI signaling sent through a shared channel.
Fig. 2 is a flow chart illustrating some embodiments of a transmission method of uplink control signaling in the present disclosure. As shown in fig. 2, the method of this embodiment includes:
in step 21, the base station transmits higher layer signaling, such as RRC signaling, including a transmission carrier indicating PUCCH information, e.g. UL carrier or SUL carrier.
In step 22, when the carrier signal where the PUCCH information is located is degraded or congestion occurs, the base station transmits PDCCH information, where the PDCCH information includes a transmission carrier indicating the PUCCH information, for example, an UL carrier or a SUL carrier.
Step 23, if the user equipment receives the PDCCH information of the transmission carrier indicating the PUCCH information, transmitting the PUCCH information on the carrier indicated by the PDCCH information, and if the PDCCH information of the transmission carrier indicating the PUCCH information is not received, transmitting the PUCCH information on the carrier indicated by the higher layer signaling according to the indication of the higher layer signaling.
The PUCCH information includes, for example, uplink control signaling such as UCI signaling, that is, UCI signaling is sent through a dedicated control channel PUCCH bearer, which is beneficial to successful demodulation of UCI, compared to UCI signaling sent through a shared channel.
According to the embodiment, on the basis of semi-statically configuring the transmission carrier of the PUCCH by the high-layer signaling, the transmission carrier of the PUCCH is dynamically configured by the physical layer signaling, so that the PUCCH transmission carrier semi-static configuration technology can be compatible, and the requirement of rapid switching of the PUCCH transmission carrier can be met.
Fig. 3 is a flowchart illustrating some embodiments of a transmission method of uplink control signaling according to the present disclosure. As shown in fig. 3, the method of this embodiment includes:
in step 31, the base station transmits scheduling information for PUCCH. The base station may schedule PUCCH through higher layer signaling or physical layer signaling.
For example, the base station may send higher layer signaling, such as RRC signaling, including a transmission carrier indicating PUCCH information, e.g., a UL carrier or a SUL carrier, to enable semi-static configuration of the PUCCH.
For another example, the base station transmits PDCCH information including a transmission carrier indicating PUCCH information, e.g., an UL carrier or a SUL carrier, and dynamic configuration of PUCCH can be achieved. The base station may dynamically schedule PUCCH by PDCCH method, for example, when the carrier signal in which PUCCH information is located is degraded or congestion occurs.
In step 32, the base station transmits the scheduling information for PUSCH. The base station may schedule PUSCH through physical layer signaling.
For example, the base station schedules PUSCH information for transmission on the UL carrier or for transmission on the SUL carrier by PDCCH signaling.
And step 33, the user equipment receives the scheduling information sent by the base station, and adopts a corresponding transmission mode according to the indication of the scheduling information.
The first transmission mode is as follows: and simultaneously transmitting PUCCH information and PUSCH information on corresponding carriers indicated by the scheduling information, wherein the PUCCH information comprises UCI signaling. The transmission carrier of the PUCCH information and the transmission carrier of the PUSCH information may be the same or different. That is, the user equipment may simultaneously transmit PUCCH information and PUSCH information on the same carrier, or may simultaneously transmit PUCCH information and PUSCH information on different carriers (e.g., UL carrier and SUL carrier). The transmission carrier of the PUCCH information is an uplink carrier or a supplementary uplink carrier. The transmission carrier of the PUSCH information is an uplink carrier or a supplemental uplink carrier.
In addition, based on the two scheduling modes of the PUCCH, if the user equipment receives PDCCH information indicating a transmission carrier of the PUCCH information, the user equipment transmits the PUCCH information on the carrier indicated by the PDCCH information, and if PDCCH information indicating a transmission carrier of the PUCCH information is not received, the user equipment transmits the PUCCH information on the carrier indicated by the higher layer signaling.
By simultaneously transmitting the PUCCH information and the PUSCH information, UCI signaling is transmitted through a special control channel PUCCH bearer, and the UCI signaling is transmitted through a shared channel relative to UCI signaling, thereby being beneficial to successful demodulation of UCI.
The second transmission mode is as follows: when there is no PUCCH information that needs to be simultaneously transmitted, UCI signaling and data may be transmitted through PUSCH.
The transmission method of the uplink control signaling in each of the above embodiments may be applicable to, for example, a 5G (fifth generation) mobile communication scenario.
