Detailed Description
In the current 5G system, the base station may instruct the UE to perform data transmission on downlink multiplexing time-frequency resources through the PDCCH based on DCI format 2-1. However, for the uplink, no technical scheme indicates that the UE multiplexes time-frequency resources, so that the UE cannot multiplex the uplink time-frequency resources for data transmission, thereby affecting the performance of the 5G network.
According to the embodiment of the invention, the related information of data multiplexing is acquired, and comprises the following steps: indication information of uplink multiplexing time-frequency resources; or, the indication information of the uplink multiplexing time-frequency resource and the indication information of the downlink multiplexing time-frequency resource indicate the related information of the data multiplexing in a multiplexing indication, and the UE can be indicated to multiplex the uplink time-frequency resource for data transmission, thereby improving the 5G network performance.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides an indication method for uplink data multiplexing, where the method may include the following steps:
step S101, obtaining related information of data multiplexing, wherein the related information of data multiplexing comprises: indication information of uplink multiplexing time-frequency resources; or, the indication information of the uplink multiplexing time-frequency resource and the indication information of the downlink multiplexing time-frequency resource.
In a specific implementation, the related information of data multiplexing may only include the indication information of uplink multiplexing time-frequency resources, and may also include the indication information of uplink multiplexing time-frequency resources and the indication information of downlink multiplexing time-frequency resources.
In a specific implementation, the indication information of the downlink multiplexing time-frequency resource refers to an existing implementation scheme, and is not described herein again.
In a specific implementation, the indication information of the uplink multiplexing time-frequency resource may include: multiplexing mode information; or, the multiplexing mode information and the multiplexed time-frequency resource information, that is, the indication information of the uplink multiplexed time-frequency resource may only include the multiplexing mode information, or may also include the multiplexing mode information and the multiplexed time-frequency resource information.
In a specific implementation, the multiplexing mode may be a preemptive mode or a reduced power transmission mode. The preemption mode represents: the multiplexed time-frequency resources are occupied by other UE, and the current UE cannot send data; the reduced power transmission mode means that data can be transmitted by reducing the transmission power.
For example, UE1 is an eMMB user terminal, UE2 is a URLLC user terminal, and to meet the low latency requirement of UE2, the base station schedules UE2 to multiplex uplink time-frequency resources of UE 1. When the base station determines that the UE2 multiplexes the uplink time-frequency resource of the UE1, the base station issues indication information of the uplink multiplexing time-frequency resource to the UE 1. And when the multiplexing mode of the uplink multiplexing time frequency resource is a preemption mode, indicating that the UE2 preempts the multiplexing time frequency resource to send URLLC data, and prohibiting the UE1 from using the multiplexing time frequency resource to send uplink data. When the multiplexing mode of the uplink multiplexing time-frequency resource is a reduced power transmission mode, it indicates that the UE1 can reduce the transmission power and transmit the eMBB data using the multiplexed time-frequency resource.
In a specific implementation, the multiplexing mode information may include: and uplink power adjustment indication information.
In an embodiment of the present invention, the uplink power adjustment indication information is 1, for example, when the adjustment value corresponding to the uplink power adjustment indication information is 1, the uplink power adjustment information indicates 0 bit, which indicates that the multiplexing mode is a preemption mode; and when a plurality of adjustment values corresponding to the uplink power adjustment indication information are provided, indicating that the multiplexing mode is a reduced power transmission mode, and indicating the adjustment value of the uplink power.
In a specific implementation, the uplink power adjustment indication information may be any one of the following information: a ratio of a Physical Uplink Shared Channel (PUSCH) power reduction, and an absolute value of a PUSCH power reduction.
In an embodiment of the present invention, the ratio of PUSCH power reduction or the absolute value of PUSCH power reduction may be indicated by 2 bits, corresponding to 4 ratio of PUSCH power reduction or the absolute value of PUSCH power reduction.
In a specific implementation, the multiplexed time-frequency resource information is a time-frequency resource in the uplink reference resource, and is used to indicate which symbols in the uplink reference resource are time-frequency resources that can be multiplexed.
In a specific implementation, the uplink reference resource includes: all symbols between the last symbol of the current uplink control resource set and the last symbol of the next uplink control resource set.
In order to make the present invention better understood and implemented by those skilled in the art, the embodiment of the present invention provides a schematic diagram of a reference resource, as shown in fig. 2.
Referring to fig. 2, a downlink reference resource is a downlink reference resource from a first symbol before a current downlink control resource set 21 to a first symbol of a previous downlink control resource set 22; the uplink reference resource is the uplink reference resource after the last symbol of the current uplink control resource set 23 to the last symbol of the next uplink control resource set 24.
In a specific implementation, a Bitmap (Bitmap) mode may be used to indicate the multiplexed time-frequency resource information.
In an embodiment of the present invention, the multiplexed time-frequency resource information includes: and the bits in the bitmap correspond to the time domain symbol groups of the uplink reference resources one to one.
In a specific implementation, the bits of the bitmap may be predetermined as fixed values, or may be indicated through Radio Resource Control (RRC) signaling.
For example, in the mode of a bitmap with frequency domain granularity × time domain granularity, when the total number of bits of the bitmap is 14, the frequency domain granularity is 1, and the time domain granularity is 14. A bit value of 0 in the bitmap indicates that the corresponding symbol group is a multiplexed time-frequency resource, that is, data needs to be transmitted with reduced power or data transmission is prohibited, and a bit value of 1 in the bitmap indicates that the corresponding symbol group does not belong to the multiplexed time-frequency resource, that is, data is transmitted without reduced power or data transmission is prohibited.
In an embodiment of the present invention, the multiplexed time-frequency resource information includes: time domain starting position of uplink reference resource.
For example, log2(K) is used to indicate the time domain starting position of the uplink reference resource, where K is an index of a starting symbol in the uplink parameter resource, and represents that time-frequency resources which are multiplexed from the beginning of K to the end of the uplink reference resource, that is, data needs to be transmitted with reduced power or data is prohibited from being transmitted.
In a specific implementation, when the indication information of the uplink multiplexing time-frequency resource only includes the multiplexing mode information and does not include the multiplexing time-frequency resource information, it may indicate that all uplink reference resources are the multiplexing time-frequency resources, that is, it is required to reduce power to transmit data or prohibit data transmission.
Step S102, in a multiplexing indication, indicating the related information of the data multiplexing.
In a specific implementation, the Group Common information (GC) of the PDCCH may be used to carry a Pre-indication (Pre-indication) on the GC-PDCCH, and multiple multiplexing indications may be carried on one GC-PDCCH. The multiplexing indication (Pre-indication) may also be carried through the PDCCH.

That is, one multiplexing indication includes: and indicating information of the uplink multiplexing time-frequency resource and indicating information of the downlink multiplexing time-frequency resource.
In specific implementation, if only the uplink multiplexing time-frequency resource function is configured, one multiplexing indication only includes indication information of the uplink multiplexing time-frequency resource; if only the downlink multiplexing time-frequency resource function is configured, one multiplexing indication only comprises the indication information of the downlink multiplexing time-frequency resource.
