The XR service not only has requirements on high reliability and low latency, but also has the properties of a high rate, unpredictable jitters, multiple streams and variable packet sizes. For example, the size ratios of an I frame and a P frame are about 3 to 6.
In video compression, each frame is a static image. In actual compression, the capacity of data may be reduced by various algorithms, in which IPB is the most common one:
An I frame is a key frame, which realizes inter-frame compression, and is similar to Audio Video Interleaved (AVI) compression.
A P frame means forward search.
A B frame means bidirectional search.
The P frame and the B frame both realize data compression based on the I frame. An I frame means a key frame, and may be understood that the picture of the frame is completely remained. Decoding can be accomplished with only data of the present frame (because the complete picture is contained). A P frame represents a difference between the current frame and a previous key frame (or P frame); and in decoding, the previously buffered picture is added to the difference defined in the current frame to generate a final picture. (That is to say, the P frame is a difference frame. The P frame does not contain complete picture data, but only data of difference with the picture of the previous frame). A B frame is a bidirectional difference frame. That is to say, the B frame records a difference between the current frame and a previous frame or a next frame, and a difference between the present frame and a following frame. In other words, when decoding a B frame, not only a previously buffered picture needs to be obtained, but also a next picture needs to be decoded; and the final picture is obtained by adding the previous picture and the next picture to data of the current frame. The B frame has a high compression rate, but a central processing unit (CPU) may be tired when performing decoding. Generally, on average, the I frame has a compression rate of 7 (almost the same as JPG), the P frame has a compression rate of 20, and the compression rate of the B frame may reach 50. It can be seen that using B frames can save large space, and the saved space may be used to stored more I frames. As such, under the same code rate, better picture quality can be provided.

Embodiment I: Enhancement of reliability and latency performance of URLLC on FR2, applicable to the scenario illustrated in
In the FR2 frequency range, fast fading of radio signals occur frequently, and the signals are very unstable. In order to improve the reliability of an FR2 Physical Downlink Shared Channel (PDSCH)/Physical Uplink Shared Channel (PUSCH)/Physical Downlink Control Channel (PDCCH)/Physical Uplink Control Channel (PUCCH), UE is configured with different numbers of data beams with different bandwidths according to different service characteristics, and each of the beams is bound to a logical channel or a logical channel group (LCG) and/or is bound to a semi-static configuration resource (such as a configured grant (CG), semi-persistent scheduling (SPS)).
In a case where the UE has 3 concurrent services. One is an XR service requiring high reliability, low latency and large data. Another is a URLLC service requiring high reliability, low latency and small data. Yet another is an enhanced mobile broadband (eMBB) service having no strict requirement on reliability and latency.
When configuring information of a logical channel and/or a logical channel group for the eMBB service of UE, the base station may also bind a downlink beam to the logical channel and/or the logical channel group, for example a downlink beam 5, or may bind no beam to the logical channel and/or the logical channel group, which is indicated by the base station using downlink control information (DCI) in dynamic scheduling.
When configuring information of a logical channel and/or a logical channel group for the XR service of UE, the base station may also bind multiple downlink beams to the logical channel and/or the logical channel group, for example a downlink beam 6, a downlink beam 7 and a downlink beam 4.
When configuring information of a logical channel and/or a logical channel group for the URLLC service of UE, the base station may also bind multiple downlink beams to the logical channel and/or the logical channel group, for example a downlink beam 6, a downlink beam 7, a downlink beam 3, a downlink beam 4 and a downlink beam 2.
To prevent service interruption and jitters caused by fast fading of beam signals during service receiving, the base station indicates no particular beam when performing downlink scheduling, but instead sends same content on one or more downlink beams bound to a logical channel and/or logical channel group corresponding to the service, and/or bound to a semi-static configuration resource (for example, a CG, SPS).
As such, the UE may receive data on one or more downlink beams with good signal quality measured by the UE itself, or the UE may receive data on any one or more downlink beams. If necessary, the UE may feed back a hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK) on corresponding uplink beams.
Alternatively, to prevent service interruption and jitters caused by fast fading of beam signals during service receiving, the base station indicates no particular beam when performing downlink scheduling, but instead selects an available beam from one or more beams bound to a logical channel and/or logical channel group corresponding to the service, and/or bound to a semi-static configuration resource (for example, a CG, SPS), and sends data on the selected beam. Therefore, the UE may perform data receiving detection on the bound beams, and may preferentially select one or more downlink (DL) beams with good signal quality measured by the UE itself and receive data on the selected beams, or the UE may receive data on any one or more DL beams. If necessary, the UE may feed back HARQ ACK/NACK on corresponding uplink beams.
Alternatively, the base station carries a DL beam use priority pattern in the DCI, and the UE receives data sequentially.
When configuring information of a logical channel and/or a logical channel group for the eMBB service of UE, the base station may also bind a beam to the logical channel and/or the logical channel group, for example an uplink beam 8, or may bind no beam, which is indicated by the base station using downlink control information (DCI) in dynamic scheduling.
When configuring information of a logical channel and/or a logical channel group for the XR service of UE, the base station may also bind multiple beams to the logical channel and/or the logical channel group, for example an uplink beam 8 and an uplink beam 9.
When configuring information of a logical channel and/or a logical channel group for the URLLC service of UE, the base station may also bind multiple beams to the logical channel and/or the logical channel group, for example an uplink beam 8, an uplink beam 9 and an uplink beam 10.
To prevent service interruption and jitters caused by fast fading of beam signals during service receiving, the base station indicates no particular beam when performing uplink scheduling, but the UE sends same content on one or more uplink beams bound to a logical channel and/or logical channel group corresponding to the service, and/or bound to a semi-static configuration resource (for example, a CG, SPS).
The UE may receive data on one or more downlink beams with good DL signal quality measured by the UE itself corresponding to uplink beams, or the UE receives data on any one or more downlink beams. Alternatively, the UE sends an uplink signal on multiple uplink beams, and the base station feeds back signal quality information of the uplink beams to the UE according to an uplink measurement result. The UE sends data on a selected subset or set of one or more beams bound to a logical channel and/or logical channel group corresponding to the service, and/or bound to a semi-static configuration resource (for example, a CG, SPS). The base station is unaware about the specific beam on which the UE sends data; thus blind detection is needed.
Then, the UE receives new data transmission scheduling or retransmission scheduling on one or more DL beams bound to a logical channel and/or logical channel group corresponding to the service, and/or bound to a semi-static configuration resource (for example, a CG, SPS).
In the above downlink and uplink receiving/sending, in order to refrain from interruption or jitter of data, when a beam fails, another one or more beams may be switched to promptly, to perform sending/receiving.
Further, the base station configures multiple groups of beams for the UE in advance, for example uplink beams. A non-access stratum (NAS) or a PDCP layer of the terminal is added with a frame type parsing capability. In a case of a packet corresponding to a key frame (namely, an I frame) in an XR service, a combination of multiple beams are configured for such a packet. In a case of a packet corresponding to a P frame and a B frame, the packet is sent only on a single beam.
The base station firstly acquires a frame type of the XR packet from a core network, or the base station itself has a parsing capability. In a case of a packet corresponding to a key frame (namely, an I frame) in an XR service, a combination of multiple beams are configured for such a packet. In a case of a packet corresponding to a P frame and a B frame, the packet is sent only on a single beam.
Additionally, when a packet of a higher layer may form a picture, the higher layer informs the indication information to a radio access side by inner primitive or by adding an indicator to the header (for example, information of a corresponding packet group, whether the packet is a last packet in the group, and information of an allowed time window in which sending of all packets in the group is completed), and the SDAP/PDCP layer needs to parse the indicator field of the packet. The base station associates these packets to a same beam group, and ensures sending of these packets on the same beam group is completed in a certain time window.
Two base stations are configured for UE. One operates in the FR1 frequency range, and the other one operates in the FR2 frequency range. Then two beam sets are configured for the UE. For example, a beam 2 and a beam 3 on the FR1, and a beam 6, a beam 7, a beam 8 and a beam 9 on the FR2. A beam selection rule is issued, for example beam numbers and types (FR1 or FR2) corresponding to different bandwidth levels of services respectively, a threshold corresponding to a channel condition on which a beam is used (downlink is measured by CRI-RS, and uplink is measured by corresponding downlink quality), beam numbers and types corresponding to different reliability levels of services, and beam numbers and types corresponding to different latency/jitter levels of a service.
The AS and the NAS of the UE requests to obtain information such as the latency/jitter, reliability, and a bandwidth requirement of the service, and autonomously selects a number and type of the beams or autonomously selects a beam group based on measured beam channel quality.
For example, a larger number of large-bandwidth beams in FR2 are selected for an XR service requiring high reliability, low latency and large data. Low-frequency FR1 beams are selected to a greatest extent for a URLLC service of small data and an eMBB service having no restrict requirement on reliability and latency. The URLLC service has more beam choices than the eMBB service.
The UE may autonomously select a beam(s) to be used in different situations according to theses preconfigured beam groups and preconfigured rules, and then feeds back the selected rule to the base station through dynamic signaling such as UL MAC signaling or uplink control information (UCI) signaling (it may be sent by an independent PUCCH or MAC signaling, or in a pickup manner of UCI multiplexed with a PUSCH (UCI multiple on PUSCH)).
